Detailed Description

[ description of embodiments of the present disclosure ]

First, embodiments of the present disclosure will be described.

The wiring member of the present disclosure is as follows.

(1) The wiring member includes a plurality of electric wires including power supply lines and communication lines extending in the same direction, and a holding member holding the plurality of electric wires, the holding member includes a plurality of electric wire holding portions capable of holding the electric wires at a certain position, respectively, the power supply line is held at a 1 st electric wire holding portion among the plurality of electric wire holding portions, the communication line is held at a 2 nd electric wire holding portion among the plurality of electric wire holding portions, and at least 1 electric wire holding portion among the plurality of electric wire holding portions is formed to be capable of adding and holding the electric wire. The power line and the communication line can be positioned by the holding member. This stabilizes the positional relationship between the power line and the communication line. In addition, at least 1 wire holding part among the plurality of wire holding parts can add and can hold the electric wire. This makes it possible to add the electric wire later and to stabilize the positional relationship of the plurality of electric wires.

(2) The plurality of wire holding portions may include a 3 rd wire holding portion, and the 3 rd wire holding portion may add and hold parallel wires extending in the same direction as the power supply line and the communication line among the plurality of wires. Thus, the holding member can hold the parallel wires parallel to the power line and the communication line, and can stabilize the positional relationship of the parallel wires in addition to the power line and the communication line. In addition, parallel wires can be added later. Therefore, after the wiring including the power supply line and the communication line and the wiring including the parallel electric wires are separately assembled, the parallel electric wires can be held by the holding member.

(3) The holding member may further include a stabilizing mechanism that contacts the parallel wires in a state corresponding to the number of the parallel wires to hold the parallel wires at a certain position with respect to the 3 rd wire holding portion. Thus, even when the number of parallel wires is different, the positional relationship of the parallel wires can be stabilized.

(4) The holding member may be provided at a plurality of locations spaced apart in a longitudinal direction of the power line and the communication line. Thus, the power line and the communication line can be bent after the holding member is attached to the power line and the communication line.

(5) The holding member may be provided at a portion where the power line and the communication line are bent, and may restrict the power line and the communication line to a bent state. Thus, the power supply line and the communication line can be restrained in a bent state by the holding member.

(6) The power supply line may include a core wire and an insulating cover portion covering the core wire, and the core wire and the insulating cover portion may be formed flat. Thereby, the height dimension of the wiring member can be reduced.

(7) The core may also be a stranded wire. This makes it easy to bend the power supply line formed flat.

[ details of embodiments of the present disclosure ]

Specific examples of the wiring member of the present disclosure will be described below with reference to the drawings. The present disclosure is not limited to these examples, but is defined by the claims, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.

[ embodiment 1]

The wiring member of embodiment 1 will be described below. Fig. 1 is a plan view illustrating a wiring member 10 of embodiment 1. Fig. 2 is a sectional view taken along line II-II of fig. 1.

The wiring member 10 includes a plurality of wires 20 and a holding member 30. The holding member 30 holds a state in which the plurality of electric wires 20 are positioned at a certain position.

Here, the plurality of wires 20 are insulated wires, respectively. The insulated wire has a core wire 21 and an insulating coating 22 covering the core wire 21. In the wiring member 10, a cable in which a plurality of insulated wires are covered with a sheath may be provided.

The core wire 21 is made of a conductive material such as copper, copper alloy, aluminum alloy, or the like. The core wire 21 may be a single core wire made of 1 wire. The core wire 21 may also include a plurality of wire rods. In the case where the core wire 21 includes a plurality of wires, the plurality of wires may be twisted or may not be twisted.

The insulating coating 22 is made of an insulating material. Typically, the insulating cover 22 is formed of a resin such as polyvinyl chloride (PVC) or Polyethylene (PE). The insulating coating 22 may be formed by extrusion molding of resin around the core wire 21, or may be formed by applying an insulating coating such as enamel paint to the periphery of the core wire 21. The insulating coating 22 is formed in a shape corresponding to the shape of the core wire 21. The insulating coating 22 is preferably formed to have the same thickness around the core wire 21.

The plurality of electric wires 20 include a power supply line 23 and a communication line 24. The power supply line 23 and the communication line 24 extend in the same direction. In the following description, when it is necessary to distinguish between the power supply line 23 and the communication line 24, the reference numerals 23 and 24 are referred to, and when it is not necessary to distinguish between them, they may be collectively referred to as the electric line 20.

Fig. 3 is a front view showing the power supply line 23 of embodiment 1. The power supply line 23 is an electric wire that supplies electric power to the connection partner of the wiring member 10. The core wire 21 and the insulating coating 22 in the power supply wire 23 are formed flat. The core wire 21 in the power supply wire 23 is a stranded wire 21 a. The stranded wire 21a is formed by stranding a plurality of (7 in the example shown in fig. 3) wire members 21 b. The strands 21a include 1 or more (8 in the example shown in fig. 3). In the example shown in fig. 3, the plurality of strands 21a are gathered to constitute 1 conductive path. Here, each of the strands 21a is not flat. The plurality of wires 21b are twisted so that the cross-sectional shape of the strand 21a is a nearly circular shape. Here, the core wire 21 becomes flat by arranging the plurality of strands 21a flat. However, the stranded wire 21a may be formed flat. In the example shown in fig. 3, 8 strands 21a are arranged in a row. The plurality of strands 21a may be arranged in a flat manner, or may be arranged in a plurality of rows. The strands 21a are in contact with each other inside the insulating coating 22. However, the strands 21a may be separated from each other inside the insulating cover 22, and may be in contact with each other at portions where the insulating cover 22 is not present, such as the end of the power supply line 23. The flat core wire 21 in the power supply wire 23 may also be a flat plate. The flat core wire 21 in the power supply wire 23 may be a core wire in which a plurality of wire materials 21b are arranged so as to extend in parallel.

The communication line 24 is an electric wire that transmits signals between the partners connected to the wiring member 10. The communication wire 24 is not formed flat. The communication line 24 is a round wire. The communication wire 24 may be a flat wire.

Here, the allowable current value in the power supply line 23 is set higher than the allowable current value in the communication line 24. Therefore, the cross-sectional area of the core wire 21 in the power supply line 23 is larger than the cross-sectional area of the core wire 21 in the communication line 24.

In the example shown in fig. 2, the power supply line 23 is 1 line. The 1 power supply line 23 is, for example, a negative power supply line. However, the number of power supply lines is not limited thereto. The number of power lines may be 2 or more. The number of power supply lines may be 2 or more, and only the power supply line on the negative side. That is, a plurality of power supply lines for different circuits may be included. The number of power supply lines may be 2 or more, including the positive side power supply line. That is, a closed circuit power line may also be included. The negative-side power supply line may be referred to as a power supply line only, and the positive-side power supply line may be referred to as a ground line.

In the example shown in fig. 2, 2 communication lines 24 are provided. The 2 communication lines 24 are, for example, communication lines 24 for CAN (Controller Area Network) communication. However, the number of communication lines is not limited thereto. The number of communication lines may be 1, or 3 or more. In the case of 1 communication line, such a communication line is, for example, a communication line for LIN (Local Interconnect Network) communication. The above is an example of a case where the communication line includes 1 bus (bus) wiring. The communication line may also include a plurality of bus wirings.

Fig. 4 is a front view showing the holding member 30 of embodiment 1. The holding member 30 includes a plurality of wire holding portions 32. The plurality of wire holding portions 32 can hold the wires 20 at predetermined positions, respectively. The wire holding portion 32 has a housing space capable of holding the wire 20 at a certain position. The plurality of wire holding portions 32 include a 1 st wire holding portion 33 and a 2 nd wire holding portion 34. In the following description, when the 1 st wire holding portion 33 and the 2 nd wire holding portion 34 need to be distinguished, reference numerals 33 and 34 are referred to, and when no particular distinction is required, they may be collectively referred to as a wire holding portion 32. The 1 st wire holding portion 33 holds the power supply wire 23. The 2 nd wire holding unit 34 holds the communication wire 24. The holding member 30 is a member integrally molded with a mold using resin or the like as a material, for example.

At least 1 wire holding part 32 of the plurality of wire holding parts 32 is formed to be able to add and hold the wire 20. Here, the 1 st wire holding portion 33 and the 2 nd wire holding portion 34 are formed to be able to add and hold the wire 20. The post-feedable wire 20 means that the post-feedable wire 20 and the holding member 30 are not integrally formed. The electric wire 20 can be added later, and it can be understood that the holding member 30 can hold the electric wire 20 formed separately from itself. The wire holding portion 32 to which the electric wire 20 can be added may be formed to be detachable and to hold the electric wire 20. Here, the 1 st wire holding portion 33 and the 2 nd wire holding portion 34 are formed to be detachable and to be able to hold the electric wire 20. The detachable electric wire 20 means: the electric wire 20 can be post-attached, and the electric wire 20 held by the holding member 30 can be detached from the holding member 30 without breaking the holding member 30. Thus, the add-on-capable wire 20 includes: the case where the electric wire 20 can be attached and detached; and when the electric wire 20 held by the holding member 30 is detached from the holding member 30, the holding member 30 needs to be broken.

The 1 st wire holding portion 33 is formed in a groove shape. The 1 st holding portion includes a bottom wall 33a and a pair of side walls 33 b. The pair of side walls 33b are provided so as to stand on both ends of the bottom wall 33 a. The side wall 33b opens between the top ends thereof. So that the power supply line 23 can be inserted from the opening. The housing space in the 1 st electric wire holding part 33 is formed in a shape corresponding to the power supply wire 23. Here, the side wall 33b is formed longer than the bottom wall 33 a. That is, the dimension from the opening to the bottom wall 33a is longer than the dimension between the pair of side walls 33 b. The bottom wall 33a is formed in a length corresponding to the thickness dimension of the power supply line 23. The side wall 33b is formed to a length corresponding to the width dimension of the power supply line 23. However, the side wall may be formed shorter than the bottom wall. That is, the dimension from the opening to the bottom wall may be shorter than the dimension between the pair of side walls. In this case, the bottom wall is formed in a length corresponding to the width dimension of the power supply line 23. The sidewall is formed to a length corresponding to the width dimension of the power supply line 23.

The 1 st wire holding portion 33 is provided with a pressing piece 36. The pressing piece 36 is provided at the top end of the side wall 33 b. The pressing piece 36 protrudes so as to close the opening of the 1 st wire holding portion 33. The pressing piece 36 protrudes toward the opposite side wall 33 b. The pressing piece 36 is provided in the pair of side walls 33b at a position separated from the bottom wall 33a by the same length dimension. However, the pressing piece 36 may be formed only on one of the pair of side walls 33 b.

The pressing pieces 36 are provided at a plurality of positions at different intervals from the bottom wall 33 a. As a result, as shown in fig. 4, the power supply line 23 of plural kinds having different width dimensions can be stored at a fixed position. That is, the pressing pieces 36 provided at a plurality of positions are the pressing pieces 36A, 36B, and 36C in order from a position close to the bottom wall 33 a. The power lines 23 of plural kinds having different width dimensions are referred to as power lines 23A, 23B, and 23C in order of smaller width dimension. In this case, when the power cord 23A is accommodated deep in the 1 st wire holding portion 33, the pressing piece 36A becomes a click of the power cord 23A. Similarly, when the power cord 23B is accommodated deep in the 1 st cord holding portion 33, the pressing piece 36B becomes a click of the power cord 23B. Similarly, when the power cord 23C is stored deep in the 1 st cord holding portion 33, the pressing piece 36C becomes a click of the power cord 23C. The pressing pieces 36A and 36B close to the bottom wall 33a are preferably elastically deformable toward the side wall 33B connected to the base end portion when the power supply line 23C corresponding to the pressing piece 36C is housed in the 1 st wire holding portion 33. Thus, when the power cord 23C is housed in the 1 st cord holding portion 33, the side wall 33b is less likely to bulge outward.

The 2 nd wire holding portion 34 is provided on the outer surface of the 1 st wire holding portion 33. Here, the 2 nd wire holding portion 34 is provided on the outer surface of the side wall 33b, but may be provided on the outer surface of the bottom wall 33 a. The 2 nd wire holding part 34 has a 1 st wall 34a protruding from the 1 st wire holding part 33 and a 2 nd wall 34b protruding from a tip of the 1 st wall 34 a. The 2 nd wire holding portion 34 is formed in an L-shape. The 2 nd wall 34b extends along the outer surface of the 1 st wire holding part 33 at a position separated from the outer surface of the 1 st wire holding part 33. The tip of the 2 nd wall 34b is open to the outer surface of the 1 st wire holding portion 33. The communication wire 24 is formed so as to be inserted through the opening. The 2 nd wire holding portion may be formed to have a plurality of walls provided at intervals on the outer surface of the 1 st wire holding portion 33. In this case, the outer surface of the 1 st wire holding part 33 constitutes the bottom of the housing space in the 2 nd wire holding part.

The housing space in the 2 nd wire holder 34 is formed in a shape capable of housing 2 communication wires 24 collectively. Here, the 2 nd wall 34b is formed longer than the 1 st wall 34 a. That is, the dimension from the opening to the 1 st wall 34a is longer than the dimension between the 2 nd wall 34b and the outer surface of the 1 st wire holding part 33. However, the 2 nd wall may be formed shorter than the 1 st wall. That is, the dimension between the 2 nd wall and the outer surface of the 1 st wire holding part 33 can also be formed short compared to the dimension from the opening to the 1 st wall.

The 2 nd wire holding unit may be a wire holding unit that separately accommodates a plurality of communication wires 24 constituting a plurality of bus lines. In this case, the 2 nd wire holding portion has, for example, a 3 rd wall extending in the opposite direction of the 2 nd wall 34b, and is formed in a T-shape.

The 2 nd wire holding portion 34 is provided with a pressing piece 37. The pressing piece 37 is provided on the top end of the 2 nd wall 34 b. The pressing piece 37 protrudes so as to close the opening of the 2 nd wire holding portion 34. The pressing piece 37 protrudes toward the outer surface of the 1 st wire holding part 33. The pressing piece 37 may be formed on the outer surface of the 1 st wire holding part 33.

The 1 st wire holding unit 33 and the 2 nd wire holding unit 34 are held in a state where the power line 23 and the communication line 24 are separated from each other. Thus, the noise applied from the power line 23 to the communication line 24 is likely to be a constant value. At this time, the power line 23 and the communication line 24 may be separated to such an extent that shielding is not necessary. A shield may also be provided between the power supply line 23 and the communication line 24. At least one of the power supply line and the communication line may be a shielded wire in which the periphery of the core wire 21 is covered with a shield.

The holding member 30 is provided with a fixing portion 39 for fixing the wiring member 10 to an object to be mounted. In the example shown in fig. 2, the fixing portion 39 is a clip 39. The clip 39 can be inserted into a hole formed in an object and locked. Clip 39 includes post 39a and retaining tab 39 b. The post 39a is formed so as to protrude from the wire holding portion 32. The locking piece 39b is provided at the tip of the column 39 a. The locking piece 39b is provided so as to spread laterally from the column 39 a. The engaging piece 39b is formed larger than the hole. When the clip 39 is inserted into the hole and the locking piece 39b abuts against the peripheral edge of the hole, the locking piece 39b is elastically deformed so as to be smaller than the hole by receiving a force from the peripheral edge of the hole. The locking piece 39b can elastically return to be larger than the hole after passing through the hole. Thus, the clip 39 can be inserted into and locked to the hole.

The fixing portion 39 is provided on the outer surface of the side wall 33 b. The fixing portion 39 may be provided on the outer surface of the bottom wall 33 a. The fixing portion 39 is provided on the side wall 33b opposite to the side wall 33b provided with the 2 nd electric wire holding portion 34. The fixing portion 39 may be provided on the same side wall 33b as the side wall 33b provided with the 2 nd electric wire holding portion 34.

The post 39a in the clip 39 extends in the thickness direction of the flat power supply cord 23. The post of the clip may be provided so as to extend in the width direction of the flat power supply line 23.

However, the fixing portion 39 is not necessarily provided in the holding member 30. Even in the case where the holding member 30 is provided with the fixing portion, the fixing portion does not need to be the clip 39. The fixing portion may be a hole, for example. The holding member 30 is fixed to the object by inserting a bolt or a clip into the hole.

The holding members 30 are provided at a plurality of locations spaced apart in the longitudinal direction of the power line 23 and the communication line 24. The power supply line 23 and the communication line 24 are bent between the 2 holding members 30. In the example shown in fig. 1, the power line 23 and the communication line 24 are bent in a direction along the main surface of the power line 23 formed flat. However, the power line 23 and the communication line 24 may be bent in other directions. The power line 23 and the communication line 24 may be bent in a normal direction with respect to a main surface of the power line 23 formed flat. The power line 23 and the communication line 24 may be bent in a direction in which the power line 23 is twisted. The power supply line 23 and the communication line 24 may be bent at a plurality of positions. The plurality of positions may be between 1 group of holding members 30 or between other groups of holding members 30. The direction of the bending may be the same or different at each position. In the example shown in fig. 1, the power supply line 23 and the communication line 24 are bent by 90 degrees, but the bending angle may be other values.

< modification of wiring Member >

Fig. 5 is a front view showing a modification of the wiring member 10 of embodiment 1. The wiring member 110 of the modification includes a plurality of wires 20 and a holding member 130. The plurality of electric wires 20 of the present embodiment are different from the plurality of electric wires 20 of embodiment 1 in that they further include parallel electric wires 25. The holding member 130 is different from the above-described holding member 30 in that the plurality of wire holding portions 32 further include the 3 rd wire holding portion 35.

The parallel wire 25 is a wire extending in the same direction as the power supply line 23 and the communication line 24. The parallel electric wires 25 are provided with 1 or more (7 in the example shown in fig. 5). The parallel electric wire 25 may include an electric wire to which electric power is supplied similarly to the power supply line 23, may include an electric wire to which a signal is transmitted similarly to the communication line 24, or may include both of them. In the example shown in fig. 5, the plurality of parallel wires 25 are the same size, but may be different sizes.

The 3 rd wire holding portion 35 can add and hold the parallel wires 25. The 3 rd wire holding portion 35 is formed in an L-shape having a 1 st wall 35a and a 2 nd wall 35b, similarly to the 2 nd wire holding portion 34. Here, the 2 nd wire holding portion 34 is provided on the outer surface of the bottom wall 33a, and the 3 rd wire holding portion 35 is provided on the outer surface of the side wall 33 b. Therefore, in the 2 nd wire holding portion 34, the 1 st wall 34a protrudes from the outer surface of the bottom wall 33a, and the 2 nd wall 34b extends along the outer surface of the bottom wall 33a at a position separated from the outer surface of the bottom wall 33 a. In the 3 rd wire holding portion 35, the 1 st wall 35a protrudes from the outer surface of the side wall 33b, and the 2 nd wall 35b extends along the outer surface of the side wall 33b at a position separated from the outer surface of the side wall 33 b. However, the 2 nd wire holding portion 34 and the 3 rd wire holding portion 35 may be provided on the outer surface of the same side wall 33 b.

The 2 nd wall 35b in the 3 rd wire holding part 35 is formed longer than the 2 nd wall 34b in the 2 nd wire holding part 34. Thereby, the 3 rd wire holding part 35 can hold a larger number of wires than the 2 nd wire holding part 34.

The retaining member 30 also includes a stabilizing mechanism 40. The stabilizing mechanism 40 is provided in the 3 rd wire holding portion 35. The stabilizing mechanism 40 contacts the parallel electric wires 25 in a state corresponding to the number of the parallel electric wires 25, and holds the parallel electric wires 25 at a certain position with respect to the 3 rd electric wire holding part 35. In the example shown in fig. 5, the stabilizing mechanism 40 includes a plurality of sheeting 42. A plurality of pressing pieces 42 are provided on the inner surface of the 2 nd wall 35 b. The plurality of pressing pieces 42 are provided at a plurality of positions with different intervals from the 1 st wall 35 a. Thus, even when the number of the parallel wires 25 is different, the parallel wires 25 can be stored at a predetermined position.

More specifically, the pressing pieces 42 provided at a plurality of positions are the pressing pieces 42A, 42B, and 42C in order from a position close to the 1 st wall 35 a. 4 parallel wires 25 can be accommodated between the 1 st wall 35a and the pressing piece 42A. 2 parallel wires 25 can be accommodated between the pressing pieces 42A and 42B. 1 parallel wire 25 can be housed between the pressing pieces 42B and 42C. Thus, even when the parallel wires 25 are different, the different numbers of the parallel wires 25 can be appropriately held at the fixed positions by the 3 rd wire holding portion 35.

Specifically, when the number of the parallel wires 25 is 1, the parallel wires are accommodated between the pressing pieces 42B and 42C. When the number of the parallel wires 25 is 2, the parallel wires are accommodated between the pressing pieces 42A and 42B. In the case of 3 parallel wires 25, 2 wires are housed between the pressing pieces 42A and 42B, and 1 wire is housed between the pressing piece 42B and 42C. When the number of the parallel wires 25 is 4, the parallel wires are accommodated between the 1 st wall 35a and the pressing piece 42A. In the case of 5 parallel wires 25, 4 wires are housed between the 1 st wall 35a and the pressing piece 42A, and 1 wire is housed between the pressing piece 42B and the pressing piece 42C. In the case of 6 parallel wires 25, 4 wires are housed between the 1 st wall 35a and the pressing piece 42A, and 2 wires are housed between the pressing piece 42A and the pressing piece 42B. In the case of 7 parallel wires 25, 4 wires are housed between the 1 st wall 35a and the pressing piece 42A, 2 wires are housed between the pressing piece 42A and the pressing piece 42B, and 1 wire is housed between the pressing piece 42B and the pressing piece 42C.

Of course, the number and arrangement of the plurality of pressing pieces 42 constituting the stabilizing mechanism 40 in the 3 rd wire holding portion 35 are not limited to the above. For example, the number of the pressed sheets 42 may be 2, or 4 or more. In addition, the number of wires to be housed between the pressing pieces 42 and the 1 st wall 35a can be set as appropriate.

< effects of embodiment 1, etc. >

According to the present embodiment, the power cord 23 and the communication cord 24 can be positioned by the holding members 30, 130. This stabilizes the positional relationship between the power line 23 and the communication line 24. In addition, at least 1 wire holding portion 32 of the plurality of wire holding portions 32 can add and hold the wire 20. This enables the electric wire 20 to be added later, and the positional relationship of the plurality of electric wires 20 to be stabilized. Since the positional relationship between the power line 23 and the communication line 24 is stable, the manner of applying noise to the communication line 24 by the power line 23 is stable. Therefore, a simple configuration can be provided regardless of whether noise measures are not required or required.

The holding members 30 and 130 are provided at a plurality of locations spaced apart from each other in the longitudinal direction of the power line 23 and the communication line 24. This allows the power line 23 and the communication line 24 to be bent after the holding member 30 is assembled.

Since the power supply line 23 is formed flat, the height dimension of the wiring member 10 can be reduced. Since the core wire 21 in the power supply wire 23 is the twisted wire 21a, the power supply wire 23 formed flat becomes easy to bend.

In addition, according to the holding member 130, the 3 rd electric wire holding part 35 in the holding member 130 can hold the parallel electric wires 25. This stabilizes the positional relationship of the parallel wires 25 in addition to the power supply line 23 and the communication line 24. The 3 rd wire holding portion 35 can be added later and can hold the parallel wires 25. Therefore, after the wiring including the power supply line 23 and the communication line 24 and the wiring including the parallel electric wires 25 are separately assembled, the parallel electric wires 25 can be held by the holding member 130. Since the stabilizing mechanism 40 is formed in the 3 rd wire holding portion 35, the positional relationship of the parallel wires 25 can be stabilized even when the number of the parallel wires 25 is different.

[ embodiment 2]

The wiring member of embodiment 2 will be explained. Fig. 6 is a plan view showing the wiring member 210 of embodiment 2. Fig. 7 is a sectional view taken along line VI-VI of fig. 6. In the description of the present embodiment, the same reference numerals are given to the same components as those described so far, and the description thereof will be omitted.

In this example, the shape of the holding member 230 is different from the shapes of the holding members 30 and 130. Specifically, the holding member 230 is the same as the holding member 130 described above in that the 3 rd wire holding part 235 can add the electric wire 20 later. The holding member 230 is different from the holding members 30 and 130 in that the 1 st wire holding portion 233 and the 2 nd wire holding portion 234 are formed so as to be able to add the wire 20. The holding member 230 is integrally formed with the power line 23 and the communication line 24.

Specifically, 2 power supply lines 23 are provided in this example. The 2 power supply wires 23 are held by the holding member 230 at positions separated in the thickness direction. The communication line 24 is located between the power supply lines 23. The 2 communication lines 24 are arranged in the same direction as the arrangement direction of the 2 power lines 23. The communication line 24 is located at a widthwise intermediate portion of the power supply line 23.

The holding member 230 is integrally formed in an H-shape having 3 plate-like portions. 2 of the 3 plate-like portions are formed as the 1 st wire holding portion 233, and the remaining 1 is formed as the 2 nd wire holding portion 234. The 21 st wire holding portions 233 can be provided separately. It can be understood that the 2 nd wire holding portion 234 is provided at a position where the intermediate portions of the 21 st wire holding portions 233 are connected. However, the holding member 230 may be configured to be able to be energized with at least one of the power line 23 and the communication line 24. In this case, for example, a groove capable of accommodating the power supply line 23 or the communication line 24 from behind may be formed in the plate-like portion.

The 21 st wire holding portions 233 open between the widthwise ends thereof. A space surrounded by the 21 st wire holding parts 233 and the 2 nd wire holding part 234 is formed as a 3 rd wire holding part 235. The 3 rd wire holding part 235 is provided with 2. The 2 rd wire holding portions 235 can accommodate the parallel wires 25.

The 3 rd wire holding portion 235 is provided with a stabilizing mechanism 240. The stabilizing mechanism 240 is different from the above-described stabilizing mechanism 40 in that the parallel electric wires 25 are held in an elastically deformed state. Specifically, the stabilization mechanism 240 has an elastic sheet 44. The elastic sheet 44 may be formed of an elastic material such as an elastomer including rubber. The elastic sheet 44 may be formed to be porous and have elastic structure, such as foamed resin including sponge. The elastic piece 44 may be formed in a plate spring shape and have elasticity. The elastic pieces 44 are arranged in an opposed manner. The elastic pieces 44 are respectively provided on the inner surfaces of the 21 st wire holding parts 233. The parallel electric wires 25 can be sandwiched between the elastic pieces 44. However, the elastic piece may be provided only on one of the 21 st wire holding portions 233. The opposing resilient tabs 44 are spaced apart in a non-contacting manner. However, the opposing elastic pieces may also be in contact.

The elastic pieces 44 are provided in a plurality in an inner surface of a 1 st wire holding portion 233 so as to be aligned from the 2 nd wire holding portion 234 side toward the opening side. However, only 1 elastic piece may be provided on the inner surface of the first 1 st wire holding portion 233. In addition, one elastic piece may have the same size as the interval of the 21 st wire holding parts 233 and be formed in a shape to be entirely accommodated in the 3 rd wire holding part 235. In this case, the elastic piece is preferably formed with a slit extending from the opening of the 3 rd wire holding portion 235 toward the bottom. The parallel electric wires 25 are inserted and held in the slits.

Fig. 8 is an explanatory diagram illustrating a case where the holding member 230 accommodates the parallel electric wires 25. In the example shown in fig. 8, 6 parallel wires 25 are stored in one of the 23 rd wire holding portions 235, and 3 parallel wires 25 are stored in the other. In this case, the amount of deformation of the elastic piece 44 in the 3 rd wire holding part 235 that houses 6 parallel wires 25 is larger than the amount of deformation of the elastic piece 44 in the 3 rd wire holding part 35 that houses 3 parallel wires 25. That is, the stabilizing mechanism 240 can hold different numbers of parallel wires 25 at a certain position by changing the amount of deformation of the elastic piece 44.

As shown in fig. 6, the holding member 230 is provided at a portion where the power line 23 and the communication line 24 are bent. The holding member 230 restricts the power cord 23 and the communication cord 24 to a bent state. The holding member 230 can receive the reaction force of the power cord 23 and the communication cord 24 to return from the bent state to the straight state. For example, after the holding member 230 is formed in a linear shape integrally with the power line 23 and the communication line 24, the holding member 230 is bent and deformed at a temperature at which it is easily deformed, and is further cooled and solidified in this state, so that the holding portion can be held in a bent and deformed state. Of course, the holding member 230 need not be provided at a portion where the power line 23 and the communication line 24 are bent, but may be provided only at a portion where the power line 23 and the communication line 24 linearly extend.

< effects of embodiment 2, etc. >

According to embodiment 2, the same operational effects as those of embodiment 1 can be obtained in addition to the operational effects obtained by scattering the holding members 30 and 130.

According to embodiment 2, the holding member 230 is provided at a portion where the power line 23 and the communication line 24 are bent. The power cord 23 and the communication cord 24 are constrained by the holding member 230 to be bent.

[ application example to vehicle ]

Fig. 9 is an explanatory diagram illustrating an example in which the wiring member 10, 110, 210 is applied to a vehicle. In the example shown in fig. 9, one end and the other end of the power line 23 and the communication line 24 are connected to the same devices 80 and 81. The power supply line 23 and the communication line 24 are the same path from one end to the other end. The holding members 30, 130, 230 are provided at least in part of intermediate portions of the power cord 23 and the communication cord 24 except for end portions (portions of the connector C) connected to the devices 80, 81. Here, holding members 130, 230 capable of holding the parallel wires 25 are provided.

One end of the parallel wires 25A is connected to the power line 23 and the communication line 24 to the same machine 80. The other end of the parallel wire 25A is connected to a device 82 different from the devices 80 and 81 connected to the power line 23 and the communication line 24. One end and the other end of the parallel wire 25B are connected to devices 83 and 84 different from the devices 80 and 81 connected to the power line 23 and the communication line 24. Therefore, some of the paths of the parallel electric wires 25A, 25B are the same paths as those of the power supply line 23 and the communication line 24. The other path of the parallel electric wires 25A, 25B is different from the paths of the power supply line 23 and the communication line 24. However, one end and the other end of the parallel wire may be connected to the same devices 80 and 81 as the power supply line 23 and the communication line 24.

It is preferable that holding members 130 and 230 capable of accommodating the parallel wires 25 be attached to portions of the power line 23 and the communication line 24 that overlap with the paths of the parallel wires 25A and 25B. Thereby, the holding members 130, 230 can hold the parallel wires 25. The holding member 30 that cannot accommodate the parallel electric wires 25 may be attached to a portion of the path of the power line 23 and the communication line 24 that does not overlap the path of the parallel electric wires 25.

For example, the devices 80 and 81 connected to the power line 23 and the communication line 24 may be power communication relay devices. The power supply communication relay device is a device that distributes power supply to 1 or a plurality of devices 82 connected to the device, or relays communication between 1 or a plurality of devices 82 connected to the device and another device. In this case, the power supply line 23 may be a wire that supplies power to the power supply communication relay apparatus. That is, the power supply line 23 is an electric wire for supplying electric power to the power distribution equipment 80, 81. Therefore, a relatively large current flows through the power supply line 23. In addition, a voltage of 12 volts is applied to the power supply line 23, for example. In addition, the communication line 24 may be a communication trunk (bus wiring).

For example, the parallel wire 25A is a wire connecting the device 80 and the device 82 as the power communication relay device. As such a machine 82, for example, a vehicle-body-based machine, an information/entertainment-based machine, or the like can be assumed. The vehicle-body-based device and the information/entertainment-based device are devices that are not directly related to the traveling of the automobile. The vehicle-body-based devices include various lighting devices, various actuators, and operation switches thereof, which are mounted on the automobile. As the lighting equipment, a headlamp, a position lamp, a brake lamp, a fog lamp, an interior lamp, and the like can be assumed, and as the actuator, an actuator such as an electric window, an electric sliding door, and the like can be assumed. Examples of the information and entertainment apparatus include a music or video reproducing apparatus, a speaker, a display device, an external communication apparatus, and a navigation apparatus. The parallel wires 25A may include either power lines or communication lines, and may be wires corresponding to the functions of the machine 82.

For example, the parallel wire 25B is a wire for connecting devices 83 and 84 other than the power communication relay device. Examples of such machines 83 and 84 include a travel-based machine, a safety-based machine, and an unmanned-vehicle-based machine. The travel-related machine is, for example, a machine related to steering, acceleration, and braking. The safety system equipment is, for example, equipment related to a safety driving support function such as an automatic brake system, an airbag, and the like. The unmanned system machine is a machine related to unmanned operation, such as a sensor (a periphery monitoring camera, a radar sensor, or the like) for monitoring the periphery of the vehicle. The parallel wires 25B may include power lines or communication lines, and wires corresponding to the machines 83 and 84 may be used.

It is preferable that the vehicle-body-based device, the information/entertainment-based device, and the like are easily changed according to the preference of the user, that is, easily customized. From this viewpoint, the 3 rd wire holding portions 35 and 235 of the holding members 130 and 230 are preferably configured to be able to attach and detach the parallel wires 25A. Travel-related devices, safety-related devices, unmanned-related devices, and the like have low necessity for easy customization as compared with vehicle-related devices, information/entertainment-related devices, and the like. From this viewpoint, the 3 rd wire holding portions 35 and 235 of the holding members 130 and 230 need only be able to add the parallel wires 25B later, and the need for detachable attachment is low. Of course, the 3 rd wire holding portions 35 and 235 may be configured to detachably hold the parallel wires 25B. In this case, maintenance of the parallel wires 25B becomes easy. As the 3 rd wire holding portion, both a detachable wire holding portion and a wire holding portion that can be added later and is not detachable may be provided. The parallel wires 25A may be held by a detachable wire holding portion, and the parallel wires 25B may be held by an undetachable wire holding portion that cannot be added later.

[ modified examples ]

Although the power supply line 23 is described above as being flat, the power supply line 23 does not have to be flat. For example, the power supply line 23 may be a round wire.

The configurations described in the embodiments and the modifications can be combined as appropriate as long as they do not contradict each other.
