Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch structure of a protector, and more particularly, to a protector for protecting a wire bundle such as a wire harness arranged in a vehicle body, electric equipment, etc. The present invention relates to a branch structure of a protector that branches.

[0002]

2. Description of the Related Art Generally, a wire harness mounted on a vehicle body or an electric device is connected to a battery or a plurality of electric circuits. Therefore, a wire harness branch line is branched from a predetermined portion of the wire harness to be connected to another electric circuit. By connecting to, the battery and a plurality of electrical circuits are connected to each other. For this reason, a protector which holds the wire harness and is arranged in a vehicle body, an electric device, or the like is provided with a branch portion for branching the wire harness branch line from the wire harness.

As a conventional branch structure of this type of protector, for example, a structure described in Japanese Utility Model Laid-Open No. 64-37319 is known, and is shown in FIGS. 5 (a) and 5 (b). Be done. In FIG. 5A, 1 is a protector body, and the protector body 1 has a wire harness 2
Are held and fixed by a tape (not shown).

A wire harness branch line 3 is branched from a predetermined position of the wire harness 1, and the wire harness branch line 3 is branched and guided by a branch plate 4 fixed to the protector main body 1 and a tape 5 is provided. It is fixed to the branch plate 4 by. Further, as shown in FIG. 5B, a branch plate 6 is swingably provided on the protector body 1 via a hinge 6 a, and the wire harness branch wire 3 is branched and guided by the branch plate 6. At the same time, it is fixed to the branch plate 6 by the tape 7.
