DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp used also as a branching jig for a wire harness and a method of assembling the wire harness using the clamp. More specifically, the present invention relates to a wire harness routed along a required route of a vehicle. The present invention relates to an operation for forming a branch of a wire harness and an improvement in workability of attaching a locking clamp to a vehicle body at the branch position.

[0002]

2. Description of the Related Art Conventionally, a wire harness that is routed along a vehicle body panel or the like of a vehicle is often locked to a vehicle body at a branch position thereof.
After branching the wire group and binding the branched wire group, it is necessary to attach a clamp for locking the vehicle body to the branch position.

In a wire harness with a clamp attached at the branch position, as shown in FIGS. 8A and 8B, a branch portion of the wire harness W / H is wound around a tape 1 and bound, and then formed into a rectangular shape. Both ends of the substrate 2 of the clamp 4 having the vehicle body engaging portion 3 protruding at the center are fixed around the wire harness W / H with tape 5.

The operation of fixing the clamp 4 to the wire harness is performed on a wire harness assembly drawing board 6 (hereinafter simply referred to as a drawing board 6) as shown in FIGS. 9 (A) to 9 (C). I have. The drawing plate 6 is provided with a U-shaped wire holding portion 7b at the upper end of a support shaft 7a and a collapsible branching jig 7 having a hinge portion 7c at the lower end. In addition, FIG.
Is provided with a retractable clamp mounting jig 8 having a wire harness mounting portion 8b at the upper end of the support shaft 8a and a hinge portion 8c at the lower end adjacent to the branch jig 7.

In the fixing operation of the clamp 4, first, as shown in FIG. 10A, the electric wire constituting the wire harness W / H is branched by the branch jig and bound by the tape 1. As shown in (B), the wire harness W / H is detached from the wire holding portion 7b of the branch jig 7, and the branch jig 7 is lowered. Next, as shown in FIG. 10 (C), the clamp mounting jig 8 is raised, and the wire harness mounting portion 8b is set.
Then, the clamp 4 is placed thereon, and as shown in FIG.
A tape 5 is wound around both ends of the substrate 2 of the clamp 4 and fixed to the wire harness W / H.

Since the clamp mounting jig 8 is used to mount the clamp 4 at a branch position of the wire harness W / H, it is preferable that the clamp mounting jig 8 is disposed at the same position as the branch jig 7. It is impossible to arrange the tool 7 and the clamp mounting jig 8 at the same position. Therefore,
As shown in FIGS. 9 and 10, the branch jig 7 and the clamp mounting jig 8 are made to be foldable, and the branch jig 7 and the clamp mounting jig 8 are arranged as close as possible. .

[0007]

However, when the clamp 4 is mounted using the branch jig 7 and the clamp mounting jig 8 as described above, there are two types of the branch jig 7 and the clamp mounting jig 8. And the branching jig 7 and the clamp mounting jig 8 need to be foldable and have a complicated structure, which increases the cost.

Further, the clamp 4 is connected to the wire harness W / H
10 (A) to 10 (A).
As described in (D), since the work of lowering or raising the branching jig 7 and the clamp mounting jig 8 is required, the number of working steps is large, and the workability is not good.

Further, as shown in FIG. 11, for example, when the outer diameter of the wire harness W / H is different on both sides of the branching position, the clamp 4 moves the wire harness W / H with the substrate 2 inclined. H. In this case, when the wire harness W / H is mounted on the vehicle body panel 11, the position of the vehicle body mounting portion 3 of the clamp 4 and the mounting hole 11a on the vehicle body panel 11 side are shifted, and the vehicle body mounting portion 3 is inserted into the mounting hole 11a. It will be difficult to do. Further, when the vehicle body mounting portion 3 is forcibly inserted into the mounting hole 11a, the tape 5 is cut, and the clamp 4 is connected to the wire harness W /.
There is a possibility that the clamp 4 may fall off from the H or the clamp 4 may be damaged.

[0010] The present invention solves the above-mentioned conventional problems, and locks a branch portion of a wire harness to a vehicle body.
