Technical Field

The present invention relates to a socket installation tool and a socket installation method for installing a socket on an electric wire.

Background

A wire cutting method is known. In the wire cutting method, an overhead wire is cut into a 1 st wire and a 2 nd wire. After necessary work is performed on the ground side of the overhead electric wire, the cut 1 st electric wire and the cut 2 nd electric wire can be connected through the sleeve.

As a related art, patent document 1 describes a stringing method. In the stringing method described in patent document 1, the coated portion of one coated electric wire is held by one holder, and the coated portion of the other coated electric wire is held by the other holder in a state where a cylindrical connecting sleeve is mounted on the core wire of the other coated electric wire. Then, the operating section of the retractor is rotated by the remote operation tool, whereby the distance between the one side holder and the other side holder is reduced, and the core wire of the covered wire on the one side is inserted into the connecting sleeve from the one end opening of the connecting sleeve.

Further, patent document 2 describes an inter-post anchor for wire cutting. The tool described in patent document 2 includes a telescopic operation body including an operation shaft, and a pair of telescopic rods each including an inner tube and an outer tube connected to both sides of the telescopic operation body. Further, wire holding members are attached to the free end sides of the inner cylinders on both sides of the telescopic operation body, and female screw portions are formed on the inner circumferential surfaces of the inner cylinders on the base end sides. Coaxial screw shafts are screwed into the female screw portions, respectively, and the screw shafts can cause the inner cylinders on both sides of the telescopic operation body to be symmetrically and simultaneously telescopically operated. When the tool is used, the operating shaft is operated to screw the threaded shaft in a predetermined direction, thereby contracting the telescopic rods on both sides of the telescopic operating body. In this way, the distance between the 2 electric wire holding members can be reduced, and the electric wires held by the 2 electric wire holding members can be loosened to perform a desired cutting operation.

Disclosure of Invention

When the 1 st electric wire and the 2 nd electric wire are connected through the sleeve, generally, the sleeve is disposed between the end of the 1 st electric wire and the end of the 2 nd electric wire, and therefore, the end of the 1 st electric wire and the end of the 2 nd electric wire must be separated by the length of the sleeve or more. When the separating operation is performed using a conventional wire cutting tool, the telescopic rod of the wire cutting tool may be extended by the length of the sleeve or more. However, if the telescopic rod is greatly extended, the slack (i.e., looseness) of the 1 st electric wire and the 2 nd electric wire becomes large, and the loose electric wires may approach or contact the electric wires located therebelow.

Therefore, an object of the present invention is to provide a sleeve installation tool and a sleeve installation method, which can suppress the looseness of the 1 st electric wire and the 2 nd electric wire when the 1 st electric wire and the 2 nd electric wire are connected through the sleeve.

Detailed Description

Hereinafter, the sleeve setting tool 1 and the sleeve setting method according to the embodiment will be described in detail with reference to the drawings. In the present specification, the same or similar reference numerals are attached to members having the same functions. Note that, the same or similar reference numerals are attached to the members, and the overlapping description may be omitted.

(definition of orientation)

In the present specification, a direction from the 2 nd slide bar 5 toward the 1 st slide bar 4 is defined as "1 st direction", and a direction from the 1 st slide bar 4 toward the 2 nd slide bar 5 is defined as "2 nd direction".

(embodiment 1)

A socket attaching tool 1A according to embodiment 1 will be described with reference to fig. 1. Fig. 1(a) to 1(d) are schematic front views of a socket attaching tool 1A according to embodiment 1.

The sleeve attaching tool 1A according to embodiment 1 includes: a base 2, a 1 st slide rod 4, a 2 nd slide rod 5, a slide rod operating part 6, a 1 st wire gripper 7a, a 2 nd wire gripper 7 b.

The base 2 includes: a sleeve support 21 supporting the sleeve SV, and a core wire support 26 supporting the exposed core wire WC.

In the example shown in fig. 1, a 1 st sleeve holder 21a for supporting one end of the sleeve SV is provided at the 1 st direction side end of the base 2, and a 2 nd sleeve holder 21b for supporting the other end of the sleeve SV is provided at the 2 nd direction side end of the base 2. In the example shown in fig. 1, the base portion 2 includes 2 sleeve supports (21a, 21b), but the number of sleeve supports included in the base portion 2 may be 1 or 3 or more. The arrangement of the sleeve holders in the base 2 is not limited to the example shown in fig. 1, and may be any arrangement.

In the example shown in fig. 1, at the end portion on the 1 st direction side of the base portion 2, the 1 st core wire supporter 26a supporting the exposed core wire WC1 of the 1 st wire W1 is provided, and at the end portion on the 2 nd direction side of the base portion 2, the 2 nd core wire supporter 26b supporting the exposed core wire WC2 of the 2 nd wire W2 is provided. In the example shown in fig. 1, the base portion 2 includes 2 core wire supporting members (26a, 26b), but the number of the core wire supporting members provided in the base portion 2 may be 3 or more. In the example shown in fig. 1, the 1 st core wire support 26a is disposed on the 1 st direction side of the sleeve support 21 (more specifically, the 1 st sleeve support 21a), and the 2 nd core wire support 26b is disposed on the 2 nd direction side of the sleeve support 21 (more specifically, the 2 nd sleeve support 21 b). In other words, the sleeve support 21 is disposed between the 1 st core support 26a and the 2 nd core support 26 b.

In the example shown in fig. 1, the sleeve holder 21 and the core holder 26 are separate bodies, but the sleeve holder 21 and the core holder 26 may be integrated. In other words, at least a portion of the sleeve support 21 may also be shared with at least a portion of the core support 26.

Further, the core wire supporter 26 may be omitted when the central axis of the exposed core wire WC and the central axis of the sleeve SV are maintained in an integrated state by a remote operation tool, or when the sleeve supporter 21 has a function of a core wire supporter.

The 1 st slide bar 4 is disposed on one side (the 1 st direction side in the example shown in fig. 1) of the base 2, and is a member that is slidable with respect to the base 2. By operating the slide rod operating portion 6, the amount of projection of the 1 st slide rod 4 from the 1 st direction side end portion 20a of the base 2 can be changed. In the example shown in fig. 1, when the slide bar operating portion 6 (more specifically, the 1 st slide bar operating portion 6a) is operated in the 1 st operating direction R1, the 1 st slide bar 4 is pulled toward the base portion 2. As a result, the amount of projection of the 1 st slide rod 4 from the 1 st direction side end 20a decreases. On the other hand, when the slide bar operating portion 6 (more specifically, the 1 st slide bar operating portion 6a) is operated in the 2 nd operating direction, the 1 st slide bar 4 moves in a direction protruding from the base portion 2 side. As a result, the amount of projection of the 1 st slide rod 4 from the 1 st direction side end 20a increases.

The 2 nd slide bar 5 is disposed on the other side (the 2 nd direction side in the example shown in fig. 1) of the base 2, and is a member that is slidable with respect to the base 2. By operating the slide rod operating portion 6, the amount of projection of the 2 nd slide rod 5 from the 2 nd direction side end portion 20b of the base 2 can be changed. In the example shown in fig. 1, when the slide bar operating portion 6 (more specifically, the 2 nd slide bar operating portion 6b) is operated in the 1 st operating direction R3, the 2 nd slide bar 5 is pulled toward the base portion 2. As a result, the amount of projection of the 2 nd slide bar 5 from the 2 nd direction side end portion 20b is reduced. On the other hand, when the slide bar operating portion 6 (more specifically, the 2 nd slide bar operating portion 6b) is operated in the 2 nd operating direction R4, the 2 nd slide bar 5 moves in a direction protruding from the base portion 2 side. As a result, the amount of projection of the 2 nd slide bar 5 from the 2 nd direction side end 20b increases.

The slide bar operating section 6 is an operating section that can slide the 1 st slide bar 4 and the 2 nd slide bar 5. In the example shown in fig. 1, the slide bar operating section 6 includes: a 1 st slide bar operating part 6a for sliding the 1 st slide bar 4; and a 2 nd slide bar operating part 6b for sliding the 2 nd slide bar 5. The sliding movement of the 1 st slide bar 4 and the sliding movement of the 2 nd slide bar 5 can be independently operated. More specifically, when the 1 st slide rod operating portion 6a is operated, the 1 st slide rod 4 moves relative to the base 2, but the 2 nd slide rod 5 does not move relative to the base 2. When the 2 nd slide rod operating portion 6b is operated, the 2 nd slide rod 5 moves relative to the base 2, but the 1 st slide rod 4 does not move relative to the base 2.

In the case where the socket attaching tool 1A has a mechanism for selectively transmitting the operation force acting on the slide bar operating portion 6 to either the 1 st slide bar 4 or the 2 nd slide bar 5, the 1 st slide bar operating portion 6a and the 2 nd slide bar operating portion 6b may be shared.

The 1 st wire gripper 7a grips the 1 st wire W1 (more specifically, the 1 st wire W1 with the unexposed portion WP 1). The 1 st wire grip 7a is connected to the end of the 1 st slide bar 4. Accordingly, when the 1 st slide rod 4 slides with respect to the base 2, the 1 st wire gripper 7a moves with respect to the base 2. In the example shown in fig. 1, the socket attaching tool 1A includes the 1 st wire grip 7 a. Alternatively, the socket attaching tool 1A may not include the 1 st electric wire gripper 7a in the shipping state or the like, and the socket attaching tool 1A may be configured to be attached to the existing 1 st electric wire gripper.

The 2 nd wire holding piece 7b holds the 2 nd wire W2 (more specifically, a portion WP2 of the 2 nd wire W2 where the core wire is not exposed). The 2 nd wire grip 7b is connected to the end of the 2 nd slide bar 5. Accordingly, when the 2 nd slide rod 5 slides with respect to the base 2, the 2 nd electric wire holder 7b moves with respect to the base 2. In the example shown in fig. 1, the socket attaching tool 1A includes the 2 nd electric wire grip 7 b. Alternatively, the socket attaching tool 1A may not include the 2 nd electric wire gripper 7b in the shipping state or the like, and the socket attaching tool 1A may be configured to be attached to the existing 2 nd electric wire gripper.

In the socket attaching tool 1A according to embodiment 1, the slide bar operating portion 6 can independently operate the sliding movement of the 1 st slide bar 4 and the sliding movement of the 2 nd slide bar 5. Accordingly, when the exposed core wire WC1 of the 1 st wire W1 is inserted into the sleeve SV, the 1 st slide rod 4 is moved by a distance shorter than the length of the sleeve SV (see fig. 1a and 1b), and when the exposed core wire WC2 of the 2 nd wire W2 is inserted into the sleeve SV, the 2 nd slide rod 5 is moved by a distance shorter than the length of the sleeve SV (see fig. 1c and 1 d). Therefore, in the step of connecting the 1 st electric wire W1 and the 2 nd electric wire W2 through the sleeve SV, enlargement of the distance between the 1 st electric wire gripper 7a and the 2 nd electric wire gripper 7b can be suppressed more than in the conventional art. As a result, the entire slack of the 1 st wire W1 and the 2 nd wire W2 can be suppressed.

The base portion 2 of the socket attaching tool 1A according to embodiment 1 may be provided so as to be separable or bendable at a substantially central portion. When the base 2 is made separable, for example, a concave portion may be provided on one side of a split body of the base 2, a convex portion may be provided on the other side of the split body, and the concave portion and the convex portion may be engaged and fixed by a screw or the like. Alternatively, the split bodies may be shaped such that the split bodies are not separated from each other when the force is applied in the 1 st direction and the 2 nd direction, and the split bodies may be coupled and/or separated by moving one split body relative to the other split body in the 1 st direction and the 2 nd direction in the vertical direction. In the case of being bendable, the base 2 may be connected by a hinge or the like so as to be bendable at a substantially central portion. Since the sleeve attaching tool 1A can be folded into 2 pieces by being divided or bent at a substantially central portion of the base portion 2, the sleeve attaching tool 1A can be downsized during transportation or storage.

Further, the distal ends of the exposed core wires WC tend to spread radially outward, and it has been conventionally not easy to insert the exposed core wires WC into the sleeve opening portion having a slightly larger inner diameter than the exposed core wires WC. In contrast, in the embodiment 1, in the case where the sleeve installation tool 1A includes the core wire support 26, in the step of inserting the exposed core wire WC into the sleeve SV, the alignment between the exposed core wire WC and the sleeve SV can be performed relatively easily. Therefore, the work of inserting the exposed core wire WC into the sleeve opening portion becomes easier. More specifically, in a state where the sleeve SV is supported by the sleeve support 21 and the exposed core wire WC is supported by the core wire support 26, the exposed core wire WC can be automatically inserted into the sleeve SV by pulling the slide bar (the 1 st slide bar 4 or the 2 nd slide bar 5) toward the base 2 side. Therefore, the operator can easily insert the exposed core wire WC into the sleeve SV.

(Sleeve installation method)

A sleeve attaching method in embodiment 1 will be described with reference to fig. 1.

In step ST1, the sleeve SV is supported by the sleeve support 21. Fig. 1(a) shows a state after step ST1 of step 1 is executed.

In the 2 nd step ST2, the 1 ST slide bar 4 is pulled toward the base 2 side, and the 1 ST wire W1 gripped by the 1 ST wire gripper 7a is moved in the 2 nd direction, whereby the exposed core wire WC1 of the 1 ST wire W1 is inserted into the 1 ST end portion of the sleeve SV. Fig. 1(b) shows a state after step 2 ST2 is executed. The 2 nd step ST2 is performed by, for example, operating the slide bar operating unit 6 (more specifically, the 1 ST slide bar operating unit 6 a).

In step ST3, the 2 nd slide bar 5 is moved in a direction protruding from the base 2 side, and the 2 nd wire W2 gripped by the 2 nd wire gripper 7b is moved in the 2 nd direction. Fig. 1(c) shows a state after step 3 ST3 is executed. The 3 rd step ST3 is performed by, for example, operating the slide bar operating unit 6 (more specifically, the 2 nd slide bar operating unit 6 b).

After the execution of step ST3, when the end portion of the exposed core wire WC2 and the 2 nd direction side end portion of the sleeve SV do not face each other, the end portion of the exposed core wire WC2 may be moved to a position facing the 2 nd direction side end portion of the sleeve SV by using a remote operation tool. More specifically, using a remote operation tool, it suffices to move the end portion of the exposed core wire WC2 and to cause the 2 nd core wire support member 26b to support the end portion.

In the 4 th step ST4, the 2 nd slide bar 5 is pulled toward the base 2 side, and the 2 nd wire W2 gripped by the 2 nd wire gripper 7b is moved in the 1 ST direction, whereby the exposed core wire WC2 of the 2 nd wire W2 is inserted into the 2 nd end portion of the sleeve SV. Fig. 1(d) shows a state after step 4 ST4 is executed. The 4 th step ST4 is performed by, for example, operating the slide bar operating unit 6 (more specifically, the 2 nd slide bar operating unit 6 b).

As described above, in the sleeve mounting method according to embodiment 1, the entire looseness of the 1 st wire W1 and the 2 nd wire W2 can be suppressed, and the sleeve SV can be mounted on the exposed core wire WC1 of the 1 st wire W1 and the exposed core wire WC2 of the 2 nd wire W2 by a simple operation.

The socket installation tool 1B may also include at least one of a 1 st wire grip 7a, a 2 nd wire grip 7B, a wire support 8, and a socket cover grip 9.

(base 2)

In the example shown in fig. 2, the base 2 includes: a rod-shaped portion 20 extending in the 1 st direction, a sleeve holder 21, a core wire holder 26, a slide rod operating portion 6.

In the example shown in fig. 2, the rod-shaped portion 20 includes a 1 st direction side end portion 20a and a 2 nd direction side end portion 20b, and is a tubular body at least a part of which is hollow. The rod-shaped portion 20 may be made of FRP (fiber reinforced plastic) or metal.

Next, the sleeve holder 21 and the core holder 26 will be described with reference to fig. 3 to 5.

In the example illustrated in fig. 3, the sleeve support 21 includes: a mounting portion 23 mounted on the rod portion 20, and a support portion 210 supporting the sleeve SV and the like. The attachment portion 23 is provided with a through-hole 231 (see fig. 4) for receiving a part of the rod-shaped portion 20. The sleeve holder 21 may also be adjustable in position relative to the rod 20 along the 1 st direction. In this case, the position of the sleeve holder 21 can be adjusted corresponding to the length of the sleeve SV actually used. Accordingly, the versatility of the socket attaching tool 1B can be improved. The sleeve holder 21 may be detachable from the rod-like portion 20. In this case, the sleeve holder 21 that is most suitable can be attached to the rod-shaped portion 20 in accordance with the diameter of the sleeve SV actually used. Accordingly, the versatility of the socket attaching tool 1B can be improved.

A sleeve holder operating portion 212 is provided on the support portion 210, and the sleeve holder operating portion 212 can change the state of the support portion between a closed state and an open state. When the supporting portion 210 is in the closed state, the supporting portion 210 restricts the sleeve SV so that the sleeve SV is substantially unable to move relative to the supporting portion 210. On the other hand, when the support portion 210 is in the open state, the sleeve SV may be placed on the support portion 210 or removed from the support portion 210. In the example illustrated in fig. 3, the sleeve holder operating portion 212 is an eye bolt (eye bolt) or an eye nut (eye nut) having a through hole that can receive the front end of the remote operation tool.

In the example shown in fig. 3, the support portion 210 includes: the 1 st portion 214 of the support sleeve SV may be inserted into the 2 nd portion 216 of the exposed core wire WC. In the example shown in fig. 3, the inner surface of the 2 nd portion 216 includes a tapered surface 216a that decreases in diameter as it goes toward the 1 st portion 214. The 2 nd portion 216 includes a tapered surface 216a, whereby the exposed core wire WC can be smoothly inserted into the 2 nd portion 216 even in the case where the distal end of the exposed core wire WC is expanded or bent. Further, the core wire guide passage 217 defined by the inner surface of the 2 nd portion 216 and the sleeve accommodating portion 215 defined by the inner surface of the 1 st portion 214 communicate with each other. Preferably, the inner surface of the 1 st portion 214 includes an end surface support surface 214a and an outer peripheral surface support surface 214b, wherein the end surface support surface 214a faces the end surface of the sleeve SV, and the outer peripheral surface support surface 214b faces the outer peripheral surface of the sleeve SV.

In the example illustrated in fig. 3, the core wire support member 26 includes: a mounting portion 23 mounted on the rod-like portion 20 of the base portion 2, and a support portion 260 supporting the exposed core wire WC and/or the coated electric wire. In the example illustrated in fig. 3, the mounting portion 23 of the core wire support member 26 is the same as the mounting portion 23 of the sleeve support member 21. In other words, the core wire support 26 and the sleeve support 21 are the shared mount portion 23. In this case, the attachment portion 23 can be attached to the rod-like portion 20 while the positional relationship between the sleeve holder 21 and the core holder 26 is maintained. As shown in the example shown in fig. 1, the attachment portion of the core wire stay 26 and the attachment portion of the sleeve stay 21 may be separate members.

A cord support operating portion 262 is provided on the support portion 260, the cord support operating portion 262 being capable of changing the state of the support portion between a closed state and an open state. When the support portion 260 is in the closed state, the support portion 260 restricts the exposed core wire WC and/or the coated wire so that the exposed core wire WC cannot move relative to the support portion 260 in the direction perpendicular to the 1 st direction. On the other hand, when the support portion 260 is in the open state, the exposed core wire WC and/or the coated electric wire may be placed on the support portion 260 or the exposed core wire WC and/or the coated electric wire may be removed from the support portion 260. In the example shown in fig. 3, the cord support operating portion 262 is an eye bolt (eye bolt) or an eye nut (eye nut) having a through hole that can receive the tip of the remote operation tool.

Preferably, the support portion 260 includes a core wire receiving portion 267 into which the exposed core wire WC and/or the coated wire can be inserted. Although not shown in fig. 3, the inner surface of the core wire receiving portion 267 may include a tapered surface that decreases in diameter as it goes toward the support portion 210 of the sleeve SV. When the core wire accommodating portion 267 includes a tapered surface, the exposed core wire WC can be smoothly inserted into the core wire accommodating portion 267.

In the example shown in fig. 3, a gap G is provided between the support portion 260 of the core wire support 26 and the support portion 210 of the sleeve support 21. With the presence of the gap G, the operator can confirm whether or not the exposed core wire WC inserted from the core wire holder 26 side has reached the sleeve holder 21. In other words, the operator can confirm whether the work of inserting the exposed core wire WC into the sleeve SV is being performed smoothly. Further, the gap G may be eliminated.

The sleeve support 21 is further explained with reference to fig. 4. In the example shown in fig. 4, the support portion 210 of the support sleeve SV includes the 1 st segment 218a and the 2 nd segment 218 b. Further, by operating the sleeve holder operating part 212, the interval between the 1 st segment 218a and the 2 nd segment 218b can be adjusted. In the example shown in fig. 4, the 1 st segment 218a and the 2 nd segment 218b can be moved closer to or away from each other along a direction (3 rd direction) perpendicular to the 1 st direction. The state in which the interval between the 1 st segment 218a and the 2 nd segment 218b is reduced corresponds to the closed state in which the restriction of the sleeve SV is imposed, and the state in which the interval between the 1 st segment 218a and the 2 nd segment 218b is enlarged corresponds to the open state in which the restriction of the sleeve SV is released.

As shown in fig. 4, a guide member 219 (e.g., a guide plate) may be provided in one of the 1 st segment 218a and the 2 nd segment 218b, and the guide member 219 may guide the insertion of the thimble SV into the thimble housing portion 215. One of the 1 st segment 218a and the 2 nd segment 218b includes a guide member 219, so that the sleeve SV can be smoothly inserted into the sleeve accommodating portion 215. Further, in the example illustrated in fig. 4, the guide member 219 includes a guide surface 219c perpendicular to the 3 rd direction.

The core wire support member 26 is further explained with reference to fig. 5. In the example shown in fig. 5, the supporting portion 260 that supports the exposed core wire WC and/or the coated electric wire includes a 1 st segment 268a and a 2 nd segment 268 b. Further, by operating the core wire holder operating part 262, the interval between the 1 st segment 268a and the 2 nd segment 268b can be adjusted. In the example shown in fig. 5, the 1 st segment 268a and the 2 nd segment 268b can be moved closer to or away from each other along a direction (3 rd direction) perpendicular to the 1 st direction. The state in which the interval between the 1 st segment 268a and the 2 nd segment 268b is reduced corresponds to the closed state in which the exposed core wire WC and/or the coated electric wire is restricted, and the state in which the interval between the 1 st segment 268a and the 2 nd segment 268b is enlarged corresponds to the open state in which the restriction of the exposed core wire WC and/or the coated electric wire is released.

As shown in fig. 5, a guide member 269 (e.g., a guide plate) may be provided in one of the 1 st segment 268a and the 2 nd segment 268b, and the guide member 269 can guide the insertion of the exposed core wire WC and/or the coated wire into the core wire accommodating portion 267. One of the 1 st segment 268a and the 2 nd segment 268b includes a guide member 269, whereby the exposed core wire WC and/or the coated electric wire can be smoothly inserted into the core wire accommodating portion 267. Further, in the example illustrated in fig. 5, the guide member 269 includes a guide surface 269c perpendicular to the 3 rd direction.

The sleeve support 21 and/or the core support 26 described in fig. 3 to 5 can be adopted as the 2 nd sleeve support 21b and/or the 2 nd core support 26b described in fig. 2. In addition, the sleeve holder 21 and/or the core holder 26 described in fig. 3 to 5 may be used as the 1 st sleeve holder 21a and/or the 1 st core holder 26a described in fig. 2.

In the example shown in fig. 2 to 5, the sleeve holder operating portion 212 and the core holder operating portion 262 are separate operating portions. Alternatively, the sleeve holder operating portion 212 and the core holder operating portion 262 may be constituted by 1 operating portion. In this case, by operating 1 operation unit, the interval between the 1 st segment 218a and the 2 nd segment 218b and the interval between the 1 st segment 268a and the 2 nd segment 268b can be adjusted simultaneously. Further, the operation portion corresponding to one of the sleeve holder and the cord holder (for example, the 1 st sleeve holder 21a and the 1 st cord holder 26a) may be constituted by one operation portion, and the operation portion corresponding to the other of the sleeve holder and the cord holder (for example, the 2 nd sleeve holder 21b and the 2 nd cord holder 26b) may be constituted by the respective operation portions (212, 262).

(No. 1 slide bar 4)

As shown in fig. 2, the 1 st slide bar 4 is an elongated member extending in the 1 st direction. The 1 st slide bar 4 may be hollow or solid. In the example shown in fig. 2, a part of the 1 st slide bar 4 is inserted into the base 2. The 1 st slide rod 4 and the 1 st slide rod operating portion 6a are configured to be able to transmit an operating force, and the amount of projection of the 1 st slide rod 4 from the base portion 2 can be changed by operating the 1 st slide rod operating portion 6 a. The 1 st slide bar 4 has a 1 st wire holder 7a connected to its tip.

(No. 2 slide bar 5)

The 2 nd slide bar 5 is an elongated member extending in the 2 nd direction. The 2 nd slide bar 5 may be hollow or solid. In the example shown in fig. 2, a part of the 2 nd slide bar 5 is inserted into the base 2. The 2 nd slide rod 5 and the 2 nd slide rod operating portion 6b are configured to be able to transmit an operating force, and the amount of projection of the 2 nd slide rod 5 from the base portion 2 can be changed by operating the 2 nd slide rod operating portion 6 b. The 2 nd wire holder 7b is connected to the tip of the 2 nd slide bar 5.

(slide bar operating part 6)

In the example shown in fig. 2, the 1 st slide rod operating part 6a and the 2 nd slide rod operating part 6b are eye bolts (eye bolts) or eye nuts (eye nuts) having through holes for receiving the tip of the remote operation tool.

An example of a mechanism for sliding the 1 st slide bar 4 with respect to the base 2 by operating the 1 st slide bar operating portion 6a with a remote operation tool will be described. In one example, consider the following: (A) the 1 st slide rod operating portion 6a is provided with a 1 st bevel gear, which is rotatable about the rotation axis AX1 together with the 1 st slide rod operating portion 6a, (B) a 2 nd bevel gear is disposed inside the base portion 2, which is connected to the 1 st bevel gear so as to be able to transmit a load, (C) the 2 nd bevel gear is rotatable about the longitudinal axis of a threaded rod having a male screw disposed on the outer periphery thereof, together with the threaded rod, and (D) the 1 st slide rod 4 is screwed to the threaded rod. In this case, when the 1 st slide rod operating portion 6a is rotated about the rotation axis AX1 by the remote operation tool, the 1 st bevel gear rotates about the rotation axis AX1, and the 2 nd bevel gear and the screw rod rotate about the longitudinal axis of the screw rod. When the threaded rod is rotated, the 1 st slide rod 4 screwed to the threaded rod moves in a direction of being pulled toward the base 2 (or in a direction of protruding from the base 2). Thus, the 1 st slide rod 4 can be relatively slidably moved with respect to the base 2.

As a mechanism for sliding the 1 st slide bar 4 with respect to the base 2 by operating the 1 st slide bar operating portion 6a, any mechanism other than the above-described mechanism may be employed.

As a mechanism for sliding the 2 nd slide bar 5 with respect to the base 2 by operating the 2 nd slide bar operating portion 6b with the remote operation tool, the same mechanism as that for sliding the 1 st slide bar 4 with respect to the base 2 by operating the 1 st slide bar operating portion 6a can be employed.

(electric wire holder 7)

The 1 st wire gripper 7a includes a 1 st gripping piece 71 and a 2 nd gripping piece 72, and grips the 1 st wire W1 (more specifically, a portion of the 1 st wire where the core wire is not exposed) by the 1 st gripping piece 71 and the 2 nd gripping piece 72. In the example shown in fig. 2, the 1 st wire gripper 7a includes a parallel link mechanism. When the 1 st wire W1 disposed between the 1 st gripping piece 71 and the 2 nd gripping piece 72 attempts to move in the 1 st direction with respect to the 1 st wire gripper 7a, the force with which the 1 st gripping piece 71 and the 2 nd gripping piece 72 grip the 1 st wire W1 increases due to the action of the parallel link mechanism.

The 1 st wire grip 7a is connected to the 1 st slide bar 4 through the 1 st connecting portion 74. Further, the connection between the 1 st wire gripper 7a and the 1 st slide bar 4 may be connected to swing about a swing axis perpendicular to the 1 st direction, or may be a non-swing connection. The 1 st electric wire grip 7a may be included in the socket setting tool 1B, or may not be included in the socket setting tool 1B. When the socket attachment 1B does not include the 1 st wire gripper 7a, the conventional 1 st wire gripper may be attached to the socket attachment 1B.

The 2 nd wire holding piece 7b is connected to the 2 nd slide bar 5 through the 2 nd connecting portion 76. Since the configuration of the 2 nd wire gripper 7b is the same as that of the 1 st wire gripper 7a, a redundant description of the 2 nd wire gripper 7b will be omitted. Further, one of the connection between the 1 st wire gripper 7a and the 1 st slide bar 4 and the connection between the 2 nd wire gripper 7b and the 2 nd slide bar 5 may be a connection swingable about a swing axis perpendicular to the 1 st direction, and the other connection may be a connection which is not swingable.

(electric wire support 8)

The wire support 8 is a member that supports the 1 st wire W1 or the 2 nd wire W2 in the region between the 1 st wire grip 7a and the 2 nd wire grip 7 b. The wire support 8 may be a member that supports the wire by directly contacting the wire (the 1 st wire W1 or the 2 nd wire W2), or a member that defines the position of the wire by surrounding the wire.

In the example shown in fig. 2, the number of the wire holders 8 is 3 (1 st wire holder 8a, 2 nd wire holder 8b, 3 rd wire holder 8 c). Alternatively, the number of the wire support 8 may be 1, 2, or 4 or more. In the example shown in fig. 2, each wire support (the 1 st wire support 8a, the 2 nd wire support 8B, the 3 rd wire support 8c, etc.) is attached to the base portion 2 of the socket attachment 1B. The 1 st wire supporter 8a is disposed on the 1 st direction side of the 1 st core supporter 26a, and the 2 nd wire supporter 8b (and the 3 rd wire supporter 8c) is disposed on the 2 nd direction side of the 2 nd core supporter 26 b.

The 1 st wire support 8a may support the end of the 1 st wire W1 (wherein "supporting end" includes "position of specified end") when forming the 1 st wire W1 and the 2 nd wire W2 by cutting the wires. The 2 nd wire support 8b supports the end of the 2 nd wire W2 after the cutting of the wire (wherein the "supported end" includes "the position of the specified end").

The 3 rd wire support 8c is disposed on the opposite side of the 2 nd wire support 8b with respect to the base 2. In other words, when the 2 nd wire support 8b is located above the base 2, the 3 rd wire support 8c is configured to be located below the base 2. The following is envisaged: the 2 nd wire W2 is moved using the remote operation tool, whereby the end position of the 2 nd wire W2 is changed from the position supported by the 2 nd wire support 8b to the position supported by the 3 rd wire support 8 c. In this case, the end portion of the 1 st electric wire W1 supported by the 1 st wire support 8a and the end portion of the 2 nd electric wire W2 supported by the 3 rd wire support 8c can be appropriately separated (for example, separated up and down).

Alternatively, or additionally, the 1 st wire support 8a and/or the 2 nd wire support 8b may also be rotatable about the longitudinal axis of the base 2. In this case, the 1 st wire supporter 8a or the 2 nd wire supporter 8b is rotated about the longitudinal axis of the base 2, whereby the end portion of the 1 st wire W1 supported by the 1 st wire supporter 8a and the end portion of the 2 nd wire W2 supported by the 2 nd wire supporter 8b can be separated (for example, vertically separated). In the case where the 1 st wire supporter 8a and/or the 2 nd wire supporter 8b are rotatable about the longitudinal axis of the base 2, the 3 rd wire supporter 8c may be omitted.

In the example shown in fig. 6, the 2 nd wire support 8b includes a housing space SP for housing a wire (for example, the 2 nd wire W2). In the example shown in fig. 6, the 2 nd wire support 8b includes a frame member 81b and an opening/closing member 82b, and the opening/closing member 82b is capable of opening/closing the opening of the frame member 81 b. The frame member 81b and the opening/closing member 82b define the housing space SP.

In the example shown in fig. 6, the 3 rd wire support 8c includes a housing space for housing a wire (for example, the 2 nd wire W2). In the example shown in fig. 6, the 3 rd wire support 8c includes a frame member 81c and an opening/closing member 82c, and the opening/closing member 82c is capable of opening/closing the opening of the frame member 81 c. The frame member 81c and the opening/closing member 82c define an accommodation space. In the example shown in fig. 2 and 6, the 3 rd wire holder 8c is integrally formed with the 2 nd wire holder 8 b. Alternatively, the 3 rd wire support 8c may be integrally formed with the 1 st wire support 8a, or may be formed separately from the 1 st wire support 8a and the 2 nd wire support 8 b.

The configuration of the 1 st wire support 8a is the same as that of the 2 nd wire support 8 b. Therefore, a detailed description of the 1 st wire support 8a is omitted herein. As shown in fig. 2, the 1 st wire support 8a includes a frame member 81a and an opening/closing member 82a, and the opening/closing member 82a is capable of opening/closing the opening of the frame member 81 a.

(Sleeve cover handle 9)

In the example shown in fig. 2, the socket attaching tool 1B includes a socket cover holder 9 for holding a socket cover SC (see fig. 13 and the like). The boot holder 9 is a boot SC arranged along the 1 st electric wire W1 or the 2 nd electric wire W2. The boot holder 9 is attached to any one of the 1 st slide bar 4, the 2 nd slide bar 5, the 1 st wire holder 7a, and the 2 nd wire holder 7b, for example.

When the sleeve attaching tool 1B includes the sleeve cover holder 9, the movement of the sleeve cover SC is suppressed and the sleeve cover SC does not hinder the work when the exposed core WC1 of the 1 st electric wire and the exposed core WC2 of the 2 nd electric wire are inserted into the sleeve SV. Further, when the sleeve SV into which the exposed core wires WC1 and WC2 are inserted is compressed by the compression tool, the movement of the sleeve cover SC is suppressed, and the sleeve cover SC does not interfere with the work. After compression of the sleeve SV, the sleeve cover SC is moved to a position covering the sleeve SV, and the connection between the sleeve SV and the exposed core wires (WC1, WC2) is protected by the sleeve cover SC.

In the example shown in fig. 2, the shroud holder 9 includes a 1 st shroud holder 9a that holds a 1 st shroud SC1 (see fig. 13 and the like) and a 2 nd shroud holder 9b that holds a 2 nd shroud SC2 (see fig. 15 and the like). The 1 st ferrule holder 9a is attached to, for example, the 1 st slide bar 4 or the 1 st wire holder 7a, and the 2 nd ferrule holder 9b is attached to, for example, the 2 nd slide bar 5 or the 2 nd wire holder 7 b.

When the sleeve cover holder 9 includes the 1 st sleeve cover holder 9a and the 2 nd sleeve cover holder 9b, a split sleeve cover may be used as the sleeve cover, and the split sleeve cover may be divided into the 1 st sleeve cover SC1 and the 2 nd sleeve cover SC 2. In the case of using the split sleeve caps, the length of each sleeve cap (the 1 st sleeve cap SC1, the 2 nd sleeve cap SC2) becomes short. Accordingly, even if the electric wire is slightly bent, the work of moving the sleeve cover along the electric wire (the 1 st electric wire W1 or the 2 nd electric wire W2) can be performed relatively easily. Further, when the 1 st sleeve cover SC1 and the 2 nd sleeve cover SC2 are moved to the position covering the sleeve SV, the 1 st sleeve cover SC1 and the 2 nd sleeve cover SC2 are coupled to each other.

An example of the structure of the sleeve cover holder 9 will be described in more detail with reference to fig. 7.

In the example illustrated in fig. 7, the sleeve cap holder 9 includes: a mounting portion 93 mounted to the slide bar (for example, the 2 nd slide bar 5) or the wire holder (for example, the 2 nd wire holder 7b), and a support portion 95 supporting the sleeve cover SC.

A sleeve cover holder operating portion 952 is provided on the support portion 95, and the sleeve cover holder operating portion 952 can change the state of the support portion 95 between a closed state and an open state. When the support 95 is in the closed state, the support 95 holds the sleeve cover SC. On the other hand, when the support portion 95 is in the open state, the sleeve cover SC may be inserted into the support portion 95, or the sleeve cover SC may be removed from the support portion 95. In the example illustrated in fig. 7, the collet cover holder operating part 952 is an eye bolt (eye bolt) or an eye nut (eye nut) having a through hole that can receive the front end of the remote operation tool.

In the example shown in fig. 7, the support portion 95 supporting the sleeve cover SC includes a 1 st divided body 958a and a 2 nd divided body 958 b. Further, by operating the sleeve cap holder operating part 952, the gap between the 1 st divided body 958a and the 2 nd divided body 958b can be adjusted. In the example shown in fig. 7, the 1 st block 958a and the 2 nd block 958b can be moved closer to or away from each other along a direction (3 rd direction) perpendicular to the 1 st direction. The state in which the distance between the 1 st divided body 958a and the 2 nd divided body 958b has decreased corresponds to the closed state in which the boot SC is gripped, and the state in which the distance between the 1 st divided body 958a and the 2 nd divided body 958b has been enlarged corresponds to the open state in which the gripped state of the boot SC is released.

The sleeve cap holder 9 described in fig. 7 may be adopted as the 2 nd sleeve cap holder 9b described in fig. 2. The mirror image of the sleeve cap holder 9 shown in fig. 7 may be adopted as the 1 st sleeve cap holder 9a shown in fig. 2.

The socket attaching tool 1B according to embodiment 2 can exhibit the same effects as those of the socket attaching tool 1A according to embodiment 1. In addition, when the socket attaching tool 1B according to embodiment 2 includes at least 1 wire holder 8, the end portion of the 1 st wire W1 can be separated from the end portion of the 2 nd wire W2. In this case, unexpected contact (short circuit) between the end of the 1 st electric wire W1 and the end of the 2 nd electric wire W2 can be suppressed. In addition, in the case where the sleeve attachment tool 1B of embodiment 2 includes at least 1 sleeve cap holder 9, the movement of the sleeve cap SC can be prevented. Therefore, the sleeve cover SC does not interfere with the work of inserting the exposed core wire into the sleeve SV or the work of compressing the sleeve SV. Further, the configuration of the wire support member 8 and/or the sleeve cover holder 9 in embodiment 2 may be adopted in embodiment 1.

(Sleeve installation method)

An example of the sleeve mounting method according to embodiment 2 will be described with reference to fig. 8 to 17. Fig. 8 is a flowchart showing an example of the sleeve attaching method according to embodiment 2. Fig. 9 to 17 are views showing a step of the sleeve mounting method, respectively.

In step ST101 of step 1, the socket attaching tool 1B is attached to the electric wire W. This mounting is performed by mounting the 1 st wire gripper 7a and the 2 nd wire gripper 7b to the wire W. In the example shown in fig. 9, the sleeve attachment 1B is attached to the electric wire W so as to face a portion (exposed portion a) where the core wire WC is exposed by peeling off the coating layer of the electric wire W. Alternatively, the exposed portion a may be formed by peeling off the coating of the electric wire W after the sleeve attachment tool 1B is attached to the electric wire W.

In the 1 ST step 101, the wire W is preferably supported by the wire supporter 8 (specifically, the 1 ST wire supporter 8a and the 2 nd wire supporter 8 b). The step of supporting the electric wire W by the electric wire support 8 is performed, for example, by moving the opening and closing members (82a, 82b) to the open position and moving the electric wire W into the frame members (81a, 81b), and then moving the opening and closing members (82a, 82b) to the closed position. In addition, any of the step of supporting the electric wire W by the wire supporter 8 and the step of attaching the 1 st wire gripper 7a and the 2 nd wire gripper 7b to the electric wire W may be performed first.

In step ST102, the interval between the 1 ST wire gripper 7a and the 2 nd wire gripper 7b is narrowed, and thereby a portion of the wire W located between the 1 ST wire gripper 7a and the 2 nd wire gripper 7b is bent (see fig. 10). The 2 nd step ST102 is performed by: the slide bar operating portion 6 (for example, the 1 st slide bar operating portion 6a) is operated to pull the 1 st slide bar 4 toward the base 2 side, and the slide bar operating portion 6 (for example, the 2 nd slide bar operating portion 6b) is operated to pull the 2 nd slide bar 5 toward the base 2 side. In addition, any of the drawing-in step of the 1 st slide bar 4 and the drawing-in step of the 2 nd slide bar 5 may be performed first. Alternatively, the drawing-in step of the 1 st slide bar 4 and the drawing-in step of the 2 nd slide bar 5 may be repeatedly performed alternately.

In step 3 ST103, the electric wire W is cut by a cutting tool between the 1 ST wire gripper 7a and the 2 nd wire gripper 7 b. By this cutting, the wire W is separated into the 1 st wire W1 and the 2 nd wire W2. Further, the cutting position is preferably a portion (exposed portion a) of the wire W where the core wire WC is exposed. In this case, by the cutting, the end of the 1 st wire W1 becomes the exposed core wire WC1, and the end of the 2 nd wire W2 becomes the exposed core wire WC 2. Instead of peeling off the coating of the electric wire before cutting the electric wire, the coating of the end portion of the 1 st electric wire W1 and the coating of the end portion of the 2 nd electric wire W2 may be peeled off after cutting the electric wire. In this case, it is not necessary to peel off the coating of the electric wire before step ST101 of step 1.

The cutting tool used in step ST103 of step 3 is, for example, a cutting tool attached to the tip of a remote operation tool. Fig. 11 shows a state after step ST103 of step 3 is performed.

As shown in fig. 12, in the 4 th step ST104, the end of the 1 ST wire W1 is separated from the end of the 2 nd wire W2 (e.g., separated up and down). The 4 th step ST104 is performed by, for example: the end of the 2 nd wire W2 is moved from the 2 nd wire support 8b toward the 3 rd wire support 8c, and the end of the 2 nd wire W2 is supported by the 3 rd wire support 8 c. Alternatively, step 4 ST104 may also be performed by: the 2 nd wire support 8b supporting the end of the 2 nd wire W2 is rotated about the longitudinal axis of the base 2.

In the 4 th step ST104, as an additional measure, the 1 ST slide rod 4 and/or the 2 nd slide rod 5 may be moved in a direction protruding from the base 2 so as to increase the distance between the end of the 1 ST wire W1 and the end of the 2 nd wire W2. This movement is performed by operating the slide bar operating portion 6 (specifically, the 1 st slide bar operating portion 6a and/or the 2 nd slide bar operating portion 6 b).

After the 4 th step ST104 is performed, an insulating cap IC (see fig. 13) may be attached to one of the end portion of the 1 ST electric wire W1 and the end portion of the 2 nd electric wire W2. Alternatively, the insulating caps may be attached to both the end of the 1 st electric wire W1 and the 2 nd electric wire W2.

In the execution of the above-described steps 1 ST101 to 4 ST104, the sleeve holder 21 and the core holder 26 are preferably in the open state. Similarly, in the execution of the above-described steps 1 ST101 to 4 ST104, the sleeve cover holder 9 is preferably in the open state.

As shown in fig. 13, in step ST105 of 5, the 1 ST ferrule cover SC1 is pushed in, the 1 ST electric wire W1 passes through the inside of the 1 ST ferrule cover SC1, and the 1 ST ferrule cover SC1 is gripped by the 1 ST ferrule cover gripper 9 a. Step ST105 of step 5 is executed by using a remote operation tool such as an insulating clamp.

Further, in the case where the insulation cap is attached to the end of the 1 ST wire W1, the insulation cap is removed from the end of the 1 ST wire W1 before the 5 th step ST105 is executed. Further, as shown by arrow B, before step 5 ST105 is executed, the 1 ST slide rod 4 may be moved in a direction protruding from the base 2.

As shown in fig. 13, in step 6 ST106, the sleeve SV is supported by the sleeve support 21. In step 6 ST106, the sleeve SV is first placed on the sleeve holder 21 using a remote operation tool such as an insulating clamp. Then, the sleeve holder operating unit 212 is operated by the remote operation tool to change the state of the sleeve holder 21 from the open state to the closed state. As a result, the support sleeve SV can be positioned by the sleeve support 21. Furthermore, when the sleeve support 21 includes the 1 st sleeve support 21a and the 2 nd sleeve support 21b, the support sleeve SV is positioned by the 1 st sleeve support 21a and the 2 nd sleeve support 21 b.

As shown in fig. 13, in the 7 th step ST107, the exposed core wires WC1 of the 1 ST wire W1 are supported by the 1 ST core-wire supporter 26 a. In the 7 th step ST107, first, the exposed core wire WC1 is moved into the 1 ST core wire support 26a using a remote operating tool. Then, using the remote operating tool, the 1 st cord support operating portion 262a is operated to change the state of the 1 st cord support 26a from the open state to the closed state. As a result, the exposed core wire WC1 can be restricted by the 1 st core wire support member 26 a. By this restriction, it is possible to perform alignment between the sleeve SV and the exposed core wire WC1 and correct the bending of the 1 st electric wire W1. As a result, the subsequent step (the step of inserting the exposed core wire WC1 into the sleeve SV) can be smoothly performed.

Step 7 ST107 may be executed before step 6 ST 106.

As shown in fig. 14, in the 8 th step ST108, the exposed core wire WC1 of the 1 ST electric wire W1 is inserted into the sleeve SV. The 8 th step ST108 is performed by: the slide bar operating portion 6 (for example, the 1 st slide bar operating portion 6a) is operated to pull the 1 st slide bar 4 toward the base portion 2 side. By executing the 8 th step ST108, the downward bending of the 1 ST wire W1 and the 2 nd wire W2 can be reduced. In addition, through the execution of step 8 ST108, the 1 ST sleeve cover SC1 is accessible to the 1 ST core support member 26 a.

The 1 st ferrule cover SC1 gripped by the 1 st ferrule cover gripper 9a may also function as a limiter for maintaining the 1 st electric wire W1 in a straight shape. Accordingly, in the case where the sleeve installation tool 1B includes the 1 st sleeve cover holder 9a, the step of inserting the exposed core wire WC1 into the sleeve SV can be performed more smoothly.

As shown in fig. 15, in step ST109, the slide bar operating portion 6 (for example, the 2 nd slide bar operating portion 6b) is operated to move the 2 nd slide bar 5 in a direction protruding from the base portion 2. By the execution of step ST109 of step 9, the exposed core wire WC2 of the 2 nd wire W2 can be retracted to the 2 nd direction side of the sleeve SV. Further, the 1 ST wire W1 and the 2 nd wire W2 are bent downward more than necessary by the execution of the 9 th step ST 109.

Further, in the case where the insulation cap is attached to the end of the 2 nd wire W2, the insulation cap is removed from the end of the 2 nd wire W2 before the 9 th step ST109 is executed.

In the 10 th step ST110, the 2 nd ferrule cover SC2 is pushed in, the 2 nd electric wire W2 passes through the inside of the 2 nd ferrule cover SC2, and then the 2 nd ferrule cover SC2 is gripped by the 2 nd ferrule cover gripper 9 b. The 10 th step ST110 is executed by using a remote operation tool such as an insulating clamp. The 10 th step ST110 is executed after the end of the 2 nd wire W2 is moved above the 2 nd slide bar 5. The movement of the end of the 2 nd wire W2 includes: for example, the end of the 2 nd wire W2 is moved from inside the 3 rd wire support 8c to inside the 2 nd wire support 8 b.

In the 11 th step ST111, the exposed core wires WC2 of the 2 nd wire W2 are supported by the 2 nd core wire support 26 b. In the 11 ST111, first, the exposed core wire WC2 is moved into the 2 nd core wire support 26b using a remote operating tool. Then, using the remote operating tool, the 2 nd core wire support operating portion 262b is operated to change the state of the 2 nd core wire support 26b from the open state to the closed state. As a result, the exposed core wire WC2 can be restricted by the 2 nd core wire support member 26 b. By this restriction, it is possible to perform alignment between the sleeve SV and the exposed core wire WC2 and correct the bending of the 2 nd wire W2.

As shown in fig. 16, in the 12 th step ST112, the exposed core wire WC2 of the 2 nd wire W2 is inserted into the sleeve SV. The 12 th step ST112 is performed by: the slide bar operating portion 6 (for example, the 2 nd slide bar operating portion 6b) is operated to pull the 2 nd slide bar 5 toward the base portion 2 side. By performing the 12 th step ST112, the downward bending of the 1 ST wire W1 and the 2 nd wire W2 can be reduced. In addition, by performing step ST112 at step 12, the 2 nd sleeve cover SC2 is accessible to the 2 nd core support 26 b.

The 2 nd sleeve cover SC2 gripped by the 2 nd sleeve cover gripper 9b may also function as a limiter for maintaining the 2 nd electric wire W2 in a straight shape. Accordingly, in the case where the sleeve installation tool 1B includes the 2 nd sleeve cover holder 9B, the step of inserting the exposed core wire WC2 into the sleeve SV can be performed more smoothly.

After the execution of step ST112 at 12, the restraint of the sleeve SV by the sleeve holder (21a, 21b), the restraint of the exposed core by the core holder (26a, 26b), and the restraint of the sleeve cover by the sleeve cover holder (9a, 9b) may be released or reduced. The release or reduction of these restrictions is performed by operating the sleeve holder operating portion 212, the core wire holder operating portion 262, and the sleeve cover holder operating portion 952 by a remote operating tool. In a state where these restrictions are released or reduced, after the 1 st slide bar 4 and/or the 2 nd slide bar 5 are pulled toward the base portion 2 side, the exposed core wire WC1 and the exposed core wire WC2 can be inserted to a deeper position in the sleeve SV. Then, the sleeve SV is compressed by the sleeve compression device, whereby the 1 st electric wire W1 and the 2 nd electric wire W2, which are originally cut, can be connected.

In step ST113 13, the socket attaching tool 1B is removed from the 1 ST electric wire W1 and the 2 nd electric wire W2.

In step 14 ST114, the 1 ST sleeve cap SC1 and the 2 nd sleeve cap SC2 are moved to positions covering the sleeve SV, and the 1 ST sleeve cap SC1 is coupled to the 2 nd sleeve cap SC 2.

The present invention is not limited to the above embodiments, and it should be understood that the embodiments may be modified or changed as appropriate within the scope of the technical idea of the present invention. In addition, any of the components used in the embodiments may be combined with other embodiments, and any of the components may be omitted in the embodiments.

For example, in the example shown in fig. 1 or 2, the slide bar operating portion 6 includes a 1 st slide bar operating portion 6a for sliding the 1 st slide bar 4 and a 2 nd slide bar operating portion 6b for sliding the 2 nd slide bar 5. Alternatively, as shown in fig. 18, the 1 st slide bar 4 and the 2 nd slide bar 5 may be independently operated by 1 slide bar operating portion 6 c.

In the example shown in fig. 18, the slide bar operating portion 6c may be selectively connected to a 1 st load transmission mechanism 61 or a 2 nd load transmission mechanism 62, wherein the 1 st load transmission mechanism 61 may drive the 1 st slide bar 4, and the 2 nd load transmission mechanism 62 may drive the 2 nd slide bar 5. More specifically, the slide bar operating portion 6c includes an operating portion side engaging portion 63, the 1 st load transmission mechanism 61 includes a 1 st engaging portion 61a engageable with the operating portion side engaging portion 63, and the 2 nd load transmission mechanism 62 includes a 2 nd engaging portion 62a engageable with the operating portion side engaging portion 63. The operation portion side engaging portion 63 can be selectively engaged with the 1 st engaging portion 61a or the 2 nd engaging portion 62 a. In this way, the operating force acting on the slide rod operating portion 6c can be selectively transmitted to the 1 st slide rod 4 or the 2 nd slide rod 5 through the 1 st engaging portion 61a or the 2 nd engaging portion 62 a.

In the example shown in fig. 18, the slide bar operating portion 6c is mounted to be movable relative to the base portion 2. A potential energy applying member 64 is provided between the slide rod operating portion 6c and the base portion 2, and the potential energy applying member 64 applies potential energy to the slide rod operating portion 6c in a direction toward the 1 st engaging portion 61a or the 2 nd engaging portion 62 a. In the example shown in fig. 18, a magnet 65 is disposed on the operation portion side engaging portion 63, and the magnet 65 is attracted to the 1 st engaging portion 61a (or the 2 nd engaging portion 62 a). Alternatively or additionally, magnets for attracting the operation portion side engaging portion 63 may be disposed on the 1 st engaging portion 61a and the 2 nd engaging portion 62a, respectively.

In the example shown in fig. 18, the 1 st load transmission mechanism 61 includes: a 1 st bevel gear 61b rotating together with the 1 st engaging part 61 a; and a 2 nd bevel gear 61e rotating together with the 1 st screw rod 61c screwed to the 1 st slide rod 4. Therefore, when the slide bar operating portion 6c is operated to rotate about the 1 st axis AT1, the 1 st engaging portion 61a engaged with the operating portion side engaging portion 63 rotates about the 1 st axis AT1 together with the 1 st bevel gear 61 b. In the example shown in fig. 18, the 1 st bevel gear 61b and the 2 nd bevel gear 61e are engaged with each other. Accordingly, when the 1 st bevel gear 61b rotates about the 1 st axis AT1, the 2 nd bevel gear 61e engaged with the 1 st bevel gear 61b rotates together with the 1 st threaded rod 61c about the 2 nd axis AT2 perpendicular to the 1 st axis AT 1. The threaded portion 61d of the 1 st threaded rod 61c is screwed to the 1 st slide rod 4. Therefore, when the 1 st screw bar 61c is rotated about the 2 nd axis AT2, the 1 st slide bar 4 is slidably moved in the direction along the 2 nd axis AT 2.

Similarly, in the example shown in fig. 18, the 2 nd load transmission mechanism 62 includes: a 3 rd bevel gear 62b rotating together with the 2 nd engaging part 62 a; and a 4 th bevel gear 62e rotating together with a 2 nd screw rod 62c screwed to the 2 nd slide rod 5. Therefore, when the slide bar operating portion 6c is operated to rotate about the 3 rd axis AT3, the 2 nd engaging portion 62a engaged with the operating portion side engaging portion 63 rotates about the 3 rd axis AT3 together with the 3 rd bevel gear 62 b. In the example shown in fig. 18, the 3 rd bevel gear 62b and the 4 th bevel gear 62e are engaged with each other. Accordingly, when bevel gear 3b rotates about axis 3 AT3, bevel gear 4 e, which is engaged with bevel gear 3b, rotates together with threaded rod 2c about axis 4 AT4, which is perpendicular to axis 3 AT 3. The threaded portion 62d of the 2 nd threaded rod 62c is screwed to the 2 nd slide rod 5. Therefore, when the 2 nd threaded rod 62c is rotated about the 4 th axis AT4, the 2 nd slide rod 5 is slidably moved in the direction along the 4 th axis AT 4. The 4 th axis AT4 and the 2 nd axis AT2 are disposed on a straight line.

In the example shown in fig. 18, it is assumed that the engagement target of the operation portion side engaging portion 63 of the slide rod operation portion 6c is switched from the 1 st engaging portion 61a to the 2 nd engaging portion 62 a. In this case, first, the slide rod operating portion 6c is moved in a direction away from the 1 st engaging portion 61a against the energizing force of the energizing member 64 and/or the attracting force of the magnet 65 using the remote operation tool. Next, the slide bar operating portion 6c is slid and moved from a position facing the 1 st engaging portion 61a to a position facing the 2 nd engaging portion 62a using the remote operation tool. It is preferable that a guide portion such as a long hole is provided in the base portion 2 to guide the sliding movement of the slide bar operating portion 6 c. Next, the slide bar operating portion 6c is engaged with the 2 nd engaging portion 62a by the energizing force of the energizing member 64 and/or the attracting force of the magnet 65.

The operation of switching the engagement target of the operation portion side engagement portion 63 of the slide rod operation portion 6c from the 2 nd engagement portion 62a to the 1 st engagement portion 61a is the same as the operation of switching the engagement target of the operation portion side engagement portion 63 of the slide rod operation portion 6c from the 1 st engagement portion 61a to the 2 nd engagement portion 62a, and therefore, a redundant description is omitted.

Fig. 19 shows a modification of the mounting portion 23 for mounting at least one of the sleeve holder 21 and the core holder 26 to the rod-like portion 20 of the base portion 2. In the example shown in fig. 19, the attachment portion 23 is detachable from the rod-like portion 20 of the base portion 2.

In the example shown in fig. 19, the mounting portion 23 includes: a mount base member 23a to which at least one of the sleeve holder 21 and the core holder 26 is mounted; and a grip member 23b that is movable relative to the mounting portion base member 23 a. When the holding member 23b is positioned at the holding position with respect to the mounting portion base member 23a, the mounting portion 23 is fixed to the rod-shaped portion 20 by the holding member 23b and the mounting portion base member 23 a. On the other hand, when the grip member 23b is positioned at the open grip position with respect to the attachment base member 23a, the attachment portion 23 can be removed from the rod portion 20 (or the attachment portion 23 can be attached to the rod portion 20).

In the example shown in fig. 19, the grip member 23b is attached to the attachment base member 23a so AS to be swingable, and the grip member 23b is swingable about the 1 st swing axis AS1 with respect to the attachment base member 23 a. The mounting portion base member 23a and the holding member 23b each have an inner surface (more specifically, an arc-shaped surface) complementary to the outer surface of the rod-shaped portion 20. An elastic body 24a for suppressing sliding with respect to the rod-like portion 20 may be disposed on the inner surface of the attachment base member 23 a. Similarly, an elastic body 24b for suppressing sliding with respect to the rod-shaped portion 20 may be disposed on the inner surface of the grip member 23 b.

In the example shown in fig. 19, a magnet 235 is disposed in the grip member 23b to hold the grip member 23b at the grip position. The magnet 235 is attracted by the mounting portion base member 23a to hold the holding member 23b at the holding position. Alternatively, or additionally, a magnet may be disposed on the mounting portion base member 23a for holding the grip member 23b at the grip position.

In the example shown in fig. 19, the mounting portion 23 includes a lock member 25, and the lock member 25 prevents the grip member 23b from moving from the grip position to the grip open position. The lock member 25 is attached to the attachment base member 23a in a swingable manner, for example. In the example shown in fig. 19, the lock member 25 is swingable about the 2 nd swing shaft AS2 with respect to the mounting base member 23 a.

When the attachment portion 23 is attached to the rod portion 20, first, the attachment base member 23a is disposed around the rod portion 20. Next, the grip member 23b is moved from the grip open position to the grip position. Thus, the attachment portion 23 can be attached to the rod portion 20. Next, the lock member 25 is moved from the lock open position to the lock position, thereby locking the grip member 23b so as not to move from the grip position.

When the attachment portion 23 is removed from the rod portion 20, the operation opposite to the operation of attaching the attachment portion 23 to the rod portion 20 may be performed.

In the example shown in fig. 19, the mounting portion 23 includes a mounting portion base member 23a and a holding member 23 b. Therefore, the attachment portion 23 can be attached to the rod portion 20 of the base 2 by a simple operation, and further, the attachment portion 23 can be detached from the rod portion 20 of the base 2 by a simple operation. The mounting portion 23 can be mounted to the rod portion 20 by a simple operation, and the position of the mounting portion 23 can be changed along the longitudinal direction of the rod portion 20 by a simple operation. In this case, the mounting position of the mounting portion 23 to the rod 20 can be easily adjusted according to the length of the sleeve SV used.

Fig. 20 shows a modification of the opening/closing operation mechanism M for opening/closing at least one of the sleeve holder 21 and the cord holder 26. In the example shown in fig. 4 or 5, the sleeve holder 21 or the core holder 26 is opened and closed by rotating operation portions (212, 262) such as a ring bolt and a ring nut. In contrast, in the example shown in fig. 20, the sleeve holder 21 or the core holder 26 is opened and closed by a swing-type operation lever (212a, 262 a). The operating levers (212a, 262a) are toggle levers (toggle lever), for example.

An example of a mechanism for opening and closing the sleeve holder 21 or the core holder 26 by the swing-type operation levers (212a, 262a) will be described with reference to fig. 20.

In the example shown in fig. 20, when the operating levers (212a, 262a) are located at the 1 st position (for example, the upper position), the supports (21, 26) are in the open state. In the example shown in fig. 20, the open state of the stays (21, 26) is a state in which the 1 st segment (218a, 268a) and the 2 nd segment (218b, 268b) are arranged separately. In the example shown in fig. 20, when the operating levers (212a, 262a) are located at the 2 nd position (for example, the lower position), the support members (21, 26) are in the locked state. In the example shown in fig. 20, the closed state of the stays (21, 26) is a state in which the 1 st divided body (218a, 268a) and the 2 nd divided body (218b, 268b) are disposed close to each other.

In the example shown in fig. 20, when the operating lever (212a, 262a) moves from the 1 st position (upper position) to the 2 nd position (lower position), the 1 st pressing body 27a presses the 1 st divided body (218a, 268a) in the direction toward the 2 nd divided body, and the 2 nd pressing body 27b presses the 2 nd divided body (218b, 268b) in the direction toward the 1 st divided body. In this way, the support members (21, 26) are in the locked state.

In the example shown in fig. 20, the potential energy applying member 28 is disposed between the 1 st segment (218a, 268a) and the 2 nd segment (218b, 268 b). The potential energy applying member 28 applies potential energy to the 1 st segment (218a, 268a) and the 2 nd segment (218b, 268b) in a direction in which the 1 st segment (218a, 268a) and the 2 nd segment (218b, 268b) are separated from each other. Therefore, when the operating lever (212a, 262a) moves from the 2 nd position (lower position) to the 1 st position (upper position), the energizing member 28 presses the 1 st divided body (218a, 268a) in a direction away from the 2 nd divided body, and the energizing member 28 presses the 2 nd divided body (218b, 268b) in a direction away from the 1 st divided body. Thus, the supporting members (21, 26) are in an open state.

In the example shown in fig. 20, the 1 st stem 29a to which the 1 st presser 27a is fixed is pivotally provided to the 1 st pin 29c, and the 1 st pin 29c is attached to the operating lever (212a, 262 a). The 2 nd presser 27b is slidably movable in the longitudinal direction of the 1 st stem 29a, and the 2 nd presser 27b is attached to the operation lever (212a, 262a) through a coupling member CN. More specifically, the coupling member CN is pivotally attached to the 2 nd pressing body 27b through the 2 nd pin 29d, and pivotally attached to the operating levers (212a, 262a) through the 3 rd pin 29 e.

In the example shown in fig. 20, when the operating lever (212a, 262a) is moved from the 1 st position (upper position) to the 2 nd position (lower position) and the operating lever (212a, 262a) is rotated about the 3 rd latch 29e, the 1 st latch 29c is rotated about the 3 rd latch 29 e. As a result, the 1 st stem 29a and the 1 st presser 27a connected to the 1 st pin 29c move in the direction approaching the 2 nd presser 27 b. In this way, the support members (21, 26) are in the locked state.

In the example shown in fig. 20, the support members (21, 26) are provided with positioning stoppers (more specifically, centering pins CP). Therefore, when the supporting piece (21, 26) is in a locking state, the supporting piece (21, 26) can be positioned at the position specified by the positioning stop piece. In the example shown in fig. 20, the position defined by the positioning stopper is a position directly above the central axis of the rod-shaped portion 20.

More specifically, the 1 st segment (218a, 268a) includes an engaging portion EN1 engageable with a positioning stopper. Therefore, the 1 st divided body (218a, 268a) cannot move to the 2 nd divided body side beyond the positioning stopper. The 2 nd divided body (218b, 268b) includes an engaging portion EN2 engageable with the positioning stopper. Therefore, the 2 nd divided bodies (218b, 268b) cannot move beyond the positioning stopper to the 1 st divided body side. Thus, the 1 st divided bodies (218a, 268a) and the 2 nd divided bodies (218b, 268b) come into contact with each other at the position where the positioning stopper is arranged.

The opening/closing operation mechanism M may be a toggle clamp (model: MC02-S2) manufactured by MISUMI corporation.

In the example shown in fig. 20, the supporters (21, 26) are opened and closed by swing-type operation levers (212a, 262 a). Thus, the opening and closing of the support members (21, 26) can be easily performed by using a remote operation tool.
