Technical Field

The present invention relates to a connecting tool for connecting wire harnesses to each other.

Background

Conventionally, a wire harness wired to a vehicle or the like is added (add-on) in which an optional wire harness is added to a base wire harness (base wire harness) as a reference in accordance with the grade of the vehicle or the like. In this case, a method of fixing the optional harness indirectly to the vehicle body by fastening and fixing the optional harness to a base harness fixed to the vehicle body is adopted. The optional harness is fixed to the base harness by a tape, or a binding tool having a clamp arm is provided to the optional harness (see, for example, patent document 1). The clamping arm is arranged as follows: the two sets are assembled from the radially outer side of the base harness to clamp the base harness, and two sets are provided in the longitudinal direction of the base harness, and the two sets are assembled with a band clip (band clip) fixed to the base harness interposed therebetween.

Disclosure of Invention

Problems to be solved by the invention

However, in the above-described structure using the binding tool, a process such as a tape winding operation is not necessary, and there is a possibility that the optional wire harness moves (is shifted) relative to the base wire harness in the longitudinal direction thereof due to a gap between the clamp arm and the tape clip, the strength of the clamp arm which needs to be bent, and the like. In addition, this becomes a cause of contact between the optional wire harness and other components, for example.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a connecting tool capable of preventing the 2 nd wire harness from moving relatively in the longitudinal direction of the 1 st wire harness.

Means for solving the problems

The connecting tool for connecting and fixing the 1 st wire harness and the 2 nd wire harness includes: a 1 st coupling tool having a coupled portion and fixed to the 1 st wire harness; and a 2 nd coupling tool having a coupling portion assembled to the coupled portion and fixed to the 2 nd wire harness; the connecting portion is attached to the connected portion in a direction along an outer surface of the 1 st wire harness when viewed in the longitudinal direction of the 1 st wire harness, and engages with the connected portion in the longitudinal direction of the 1 st wire harness.

According to this configuration, the 1 st wire harness and the 2 nd wire harness are connected and fixed by assembling the connection portion of the 2 nd connector fixed to the 2 nd wire harness to the connection portion of the 1 st connector fixed to the 1 st wire harness. Then, the coupling portion is assembled to the coupled portion in a direction along an outer surface of the 1 st wire harness when viewed in the longitudinal direction of the 1 st wire harness, and engages with the coupled portion in the longitudinal direction of the 1 st wire harness, thereby preventing the 2 nd wire harness from moving relatively in the longitudinal direction of the 1 st wire harness.

In the above coupling tool, it is preferable that one of the coupling portion and the coupled portion is provided with a locking claw which engages with the other to function as a coming-off preventing portion in an assembled state.

According to this configuration, since the engagement claw that engages with the other of the connecting portion and the coupled portion and functions as the coming-off prevention portion in the assembled state is provided on one of the connecting portion and the coupled portion, the 2 nd wire harness is prevented from moving relatively in the direction of the outer surface of the 1 st wire harness.

In the above-described coupling tool, it is preferable that the coupling portion includes a guide portion that guides the coupling portion to be assembled to the coupled portion in a state where the guide portion is displaced in a direction orthogonal to a direction of an outer surface of the 1 st wire harness when viewed from a longitudinal direction of the 1 st wire harness.

According to this configuration, since the coupling portion has the guide portion that guides the assembly of the coupling portion to the coupled portion in a state where the coupling portion is displaced in a direction orthogonal to the direction of the outer surface of the 1 st wire harness as viewed in the longitudinal direction of the 1 st wire harness, the assembly work is easy.

In the above coupling tool, it is preferable that the guide portion includes a harness sliding guide portion that slides on an outer surface of the 1 st harness to guide the harness.

According to this configuration, since the guide portion includes the harness sliding guide portion that slides on the outer surface of the 1 st harness to guide the harness, the harness sliding guide portion of the connection portion can be assembled by sliding on the outer surface of the 1 st harness to guide the harness, and the assembly work is easy.

In the above coupling tool, it is preferable that the wire harness sliding guide part is one of a pair of wire harness sliding guide parts provided at both ends of the coupling part corresponding to the longitudinal direction of the 1 st wire harness.

According to this configuration, since the harness sliding guide portions are provided at both ends of the connecting portion corresponding to the longitudinal direction of the 1 st harness, the pair of harness sliding guide portions of the connecting portion can be assembled by sliding and stably guiding the pair of harness sliding guide portions and the outer surface of the 1 st harness, and therefore, the assembly work is easy.

Effects of the invention

According to the connector of the present invention, the 2 nd wire harness can be prevented from moving relatively in the longitudinal direction of the 1 st wire harness.

Detailed Description

An embodiment of a composite harness fastened and fixed by a fastening tool will be described below with reference to fig. 1 to 8.

As shown in fig. 1 and 2, a connector 1 is a member that forms a composite harness by connecting and fixing an optional harness 3 as a 2 nd harness to a base harness 2 as a 1 st harness wired to a vehicle. The base harness 2 and the optional harness 3 of the present embodiment are formed in a substantially circular shape in cross section, and the optional harness 3 is smaller in diameter than the base harness 2.

The connector 1 includes: a 1 st connector 5 having a connected portion 4 and fixed to the base harness 2; and a 2 nd connecting tool 7 which is assembled to the connecting portion 6 of the connected portion 4 and fixed to the optional harness 3.

The coupling portion 6 is configured to: the base harness 2 is assembled to the coupled portion 4 from a direction along an outer surface of the base harness 2 (in the present embodiment, a direction along a wire connection of the outer periphery of the base harness 2) when viewed from the longitudinal direction of the base harness 2 (see fig. 2), and engages with the coupled portion 4 in the longitudinal direction of the base harness 2 (a direction perpendicular to the paper surface in fig. 2).

Specifically, as shown in fig. 3 and 4, the 1 st coupling tool 5 includes the coupled portion 4 and the binding portion 8 fixed to the base wire harness 2. The band portion 8 has a substantially rectangular tubular band locking box portion 8b having a claw portion 8a on the inner surface and a band portion 8c extending from the back surface (the right surface in fig. 3 and 4) of the band locking box portion 8b, and is fixed to the base harness 2 by winding the band portion 8c around the base harness 2 and inserting the tip end thereof into the band locking box portion 8b to tighten the same. The coupled portion 4 includes a front side protruding portion 4a protruding from the front side of the band locking box portion 8b to both sides (upper and lower sides in fig. 4), and a rear side protruding portion 4b protruding from the rear side of the band locking box portion 8b to both sides, and has an assembly groove 4c formed by the front side protruding portion 4a, the side surface of the band locking box portion 8b, and the rear side protruding portion 4 b. The coupled portion 4 includes a locking claw 4d protruding from the front surface of the binding band locking box portion 8 b.

As shown in fig. 5 to 7, the 2 nd connector 7 includes the connection portion 6 and a harness fixing portion 9 fixed to the optional harness 3. The wire harness fixing portion 9 is formed in a plate shape, extends from a side surface (lower surface in fig. 1) of the connecting portion 6 along another surface (lower surface in fig. 1) in the longitudinal direction of the optional wire harness 3, and is wound with a tape 10 together with the optional wire harness 3 to be fixed to the optional wire harness 3. The coupling portion 6 includes a base wall 6a facing the front surface of the band locking box portion 8b of the first coupling tool 5, a pair of facing walls 6b projecting from the base wall 6a and facing the side surfaces of the band locking box portion 8b, and a coupling wall 6c coupling the tip end sides of the facing walls 6b and facing the upper surface (upper surface in fig. 3) of the band locking box portion 8 b. The coupling portion 6 includes a pair of assembly extending portions 6d extending downward from both sides of the coupling wall 6c along the opposing wall 6b and fitted in the assembly grooves 4c, respectively. Further, a claw fitting recess 6e (see fig. 5) into which the locking claw 4d is fitted is formed in the base wall 6a of the coupling portion 6.

The coupling portion 6 is assembled to the coupled portion 4 from a direction along the outer surface of the base wire harness 2 (in the present embodiment, a direction along the wiring of the outer periphery) in such a manner that the assembly extending portion 6d is fitted into the assembly groove 4c of the coupled portion 4 and the front side protruding portion 4a is fitted between the base wall 6a and the assembly extending portion 6d (see fig. 4). At this time, the coupling portion 6 is assembled so that the upper surface of the strap locking box portion 8b abuts against the coupling wall 6c, and the coupling portion 6 in this state is prevented from being detached from the coupled portion 4 by the engagement of the engagement claws 4d with the claw fitting recesses 6e (in the direction opposite to the assembling direction). In the coupling portion 6 in the assembled state, the opposing wall 6b and the assembly extension portion 6d are engaged with the front side protruding portion 4a and the assembly groove 4c of the coupled portion 4 in the longitudinal direction (vertical direction in fig. 4) of the base harness 2.

The coupling portion 6 of the present embodiment includes an opening guide portion 6f as a guide portion for guiding the assembly of the coupling portion 6 to the coupled portion 4 from a state where the guide portion is displaced in a direction (left-right direction in fig. 8) orthogonal to a direction along an outer surface of the base wire harness 2 when viewed in the longitudinal direction of the base wire harness 2, and a wire harness sliding contact guide portion 6 g. In addition, the guidance described herein is: when the coupling portion 6 moves in the direction of the outer surface (the assembly direction, downward in fig. 8) in a state of being displaced in the orthogonal direction (the left-right direction in fig. 8), the position in the orthogonal direction is moved to the position where assembly is possible. The opening guide portion 6f is formed on the lower end side (lower end side in fig. 8) of the base wall 6a and the assembly extension portion 6d, and is inclined so that the interval becomes larger toward the lower end. The harness sliding guide 6g is formed at the lower end of a bulging portion 6h bulging from the front end of the opposing wall 6b, and is formed by bending so that the angle thereof is R-shaped. That is, as shown by the two-dot chain line in fig. 8, when the harness sliding guide portion 6g moves downward from the position of contact with the base harness 2, it slides against the outer peripheral surface of the base harness 2, and guides the coupling portion 6 (leftward in fig. 8) as shown by the solid line in fig. 8. When the opening guide portion 6f moves downward from the arrangement state shown by the solid line in fig. 8, it comes into contact with (slides on) the front side protruding portion 4a, and guides the coupling portion 6 (leftward in fig. 8) so that the front side protruding portion 4a fits between the base wall 6a and the assembly extending portion 6 d.

Next, the operation of the coupling tool 1 configured as described above will be described.

For example, when the optional harness 3 is additionally provided to the base harness 2 in accordance with the grade of the vehicle or the like, the base harness 2 and the optional harness 3 are connected and fixed by assembling the connection portion 6 fixed to the 2 nd connector 7 of the 1 st connector 5 fixed to the base harness 2 to the connected portion 4. In this way, for example, only the base harness 2 may be fixed to the vehicle body, and the optional harness 3 may also be fixed to the vehicle body via the base harness 2.

Next, the effects of the above embodiment will be described.

(1) The base harness 2 and the optional harness 3 are connected and fixed by assembling the connection portion 6 of the 2 nd connector 7 fixed to the optional harness 3 to the connected portion 4 of the 1 st connector 5 fixed to the base harness 2. The coupling portion 6 is attached to the coupled portion 4 in a direction along the outer surface of the base harness 2 (in a direction along the outer periphery of the wiring) when viewed in the longitudinal direction of the base harness 2, and engages with the coupled portion 4 in the longitudinal direction of the base harness 2, thereby preventing the optional harness 3 from moving relatively in the longitudinal direction of the base harness 2. As a result, for example, the optional harness 3 is prevented from being displaced from a predetermined position and coming into contact with another member.

(2) The fastened portion 4 is provided with a locking claw 4d that engages with the fastening portion 6 and functions as a drop-off prevention portion from the assembled state, and therefore, the optional harness 3 is prevented from moving relatively in a direction along the outer surface of the base harness 2.

(3) The coupling portion 6 includes an opening guide portion 6f as a guide portion for guiding the assembly of the coupling portion 6 to the portion to be coupled 4 from a state displaced in a direction (left-right direction in fig. 8) orthogonal to the direction along the outer surface of the base harness 2 when viewed in the longitudinal direction of the base harness 2, and a harness sliding guide portion 6g, which facilitates the assembly operation.

(4) Since the guide portion includes the wire harness sliding guide portion 6g which is guided in sliding contact with the outer surface of the base wire harness 2, the wire harness sliding guide portion 6g of the connection portion 6 can be assembled in sliding contact with and guided by the outer surface of the base wire harness 2, and therefore the assembly work is easy. That is, as shown by the two-dot chain line in fig. 8, even if the assembly work is started by largely shifting the position of the coupling portion 6 in the orthogonal direction (right direction in fig. 8), the wire harness sliding guide portion 6g can be easily assembled to the coupled portion 4 by sliding the wire harness sliding guide portion 6g on the outer peripheral surface of the base wire harness 2.

(5) Since the harness sliding guide portions 6g are provided at the opposite ends of the connecting portion 6 corresponding to the longitudinal direction of the base harness 2, that is, the opposing walls 6b, the pair of harness sliding guide portions 6g of the connecting portion 6 can be slid to the outer surface of the base harness 2 to be stably guided and assembled, and therefore, the assembly work is easier.

(6) The 2 nd connecting tool 7 has a wire harness fixing portion 9 extending from the connecting portion 6 in one of the longitudinal directions of the optional wire harness 3, and is fixed to the optional wire harness 3 only by this wire harness fixing portion 9, so that the other direction side of the optional wire harness 3 in the longitudinal direction can be bent from a position corresponding to the connecting portion 6 (see fig. 1).

The above embodiment may be modified as follows.

In the above embodiment, the coupling target portion 4 is provided with the locking claw 4d which engages with the coupling portion 6 and functions as a slip-off prevention portion in the assembled state, but the execution function locking claw may be provided on the coupling portion 6 side in the same manner, or the assembled state may be maintained by other configurations such as press fitting without providing the locking claw.

In the above embodiment, the coupling portion 6 has the guide portions (the opening guide portion 6f and the harness sliding contact guide portion 6g) that guide the assembly of the coupling portion 6 to the coupled portion 4 in a state where the coupling portion 6 is displaced from the direction (the left-right direction in fig. 8) orthogonal to the direction along the outer surface of the base harness 2 when viewed in the longitudinal direction of the base harness 2. The guide portion may be constituted by only one of the split guide portion 6f and the wire harness sliding guide portion 6g, or may be constituted by another guide portion having the same function.

In the above embodiment, the 2 nd coupling tool 7 has the harness fixing portion 9 extending from the coupling portion 6 in one of the longitudinal directions of the optional harness 3, and is fixed to the optional harness 3 only by the harness fixing portion 9, but is not limited thereto, and may be fixed to the optional harness 3 by another configuration. For example, a wire harness fixing portion extending from the connecting portion 6 in the other longitudinal direction of the optional wire harness 3 may be further provided, and both the wire harness fixing portions may be fixed to the optional wire harness 3. The 1 st connector 5 may be fixed to the base harness 2 by a structure other than the binding band portion 8.

In the above embodiment, the base harness 2 and the optional harness 3 have a substantially circular cross section, but the present invention is not limited thereto, and may be embodied by a base harness or an optional harness having a cross section other than a circular shape.

The technical idea that can be grasped from the above-described embodiments is described below.

A connector is characterized in that: the 2 nd coupling tool has a harness fixing portion extending from the coupling portion in one of the longitudinal directions of the 2 nd wire harness, and is fixed to the 2 nd wire harness only by the harness fixing portion.

According to this configuration, since the 2 nd coupling tool has the harness fixing portion extending from the coupling portion in one of the longitudinal directions of the 2 nd wire harness and is fixed to the 2 nd wire harness only by the harness fixing portion, the other longitudinal direction side of the 2 nd wire harness can be bent from the position corresponding to the coupling portion.

It is obvious to a person skilled in the art that the invention can be embodied in other specific ways without departing from the scope of the technical idea thereof. For example, a part of the components described in the embodiment (or 1 or more modes thereof) may be omitted, or a plurality of components may be combined. The scope of the invention should be determined, with reference to the appended claims, by all ranges of equivalents to which the claims are entitled.
