Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for mounting a resin rod on a wire harness, and more specifically, when a wire harness is assembled, a resin rod for restricting the wire harness in a required direction and angle is provided. By positioning and holding the wire in the position and placing it along the wire harness, the workability of mounting the wire harness is improved.

[0002]

2. Description of the Related Art In particular, in a wire harness for an automobile, a complicatedly branched electric wire bundle must be routed along a predetermined route, and therefore, in a specific portion of a main line or a branch line, It may be necessary in advance to regulate the form of the wire harness so as to match the wiring route.
Therefore, a resin rod molded corresponding to the form to be restricted is taped along the wire harness to restrict a specific portion of the wire harness in a predetermined direction and angle.

To attach the resin rod to the wire harness, as shown in FIGS. 9 (A) and 9 (B), the U-shaped electric wire holder 1 is set upright on a predetermined path on the assembly table. In the process of laying the wire harness W / H along the
Indicator rod 2 that serves as a mark corresponding to the place where the attachment of the
To stand. Then, using the position of the indicator rod 2 as a guide,
One end of the resin rod B which should be along the wire harness W / H is positioned, the other end is fixed to the wire harness W / H with the tape T, and then the indicator rod 3 is attached as shown in FIG. 9 (B). Similarly, the end portion on the side is fixed with the tape T.

[0004]

However, since the resin rod is attached only by a standard with the indicator rod as a reference, the resin rod should always be attached accurately along the outer peripheral predetermined position of the wire harness. Was difficult.

The present invention has been made in view of the above problems, and improves the accuracy of the mounting position of the resin rod with respect to the wire harness by preliminarily holding the resin rod in a predetermined position and direction on the assembly table.
