Description

  The present invention relates to a protector for a wire harness, and more specifically, in order to branch a part of a wire harness accommodated in the protector, an opening for leading the branched wire harness to the outside is provided in the protector by secondary processing. There is no need, and the branch position of the wire harness can be easily changed.

Conventionally, in order to protect a wire harness used for wiring of various electrical components mounted on an automobile, a protector made of a synthetic resin that houses the wire harness is provided.
As the protector, for example, in Japanese Patent Application Laid-Open No. 9-117032, as shown in FIG. 6 (A), a cover 1b that can freely open and close the upper surface opening is provided on an upper portion of a bowl-shaped protector body 1a having an upper surface opened. When the wire harness W / H is accommodated in the protector main body 1a and the cover 1b is closed as shown in FIG. 6B, the lock claw 1d of the cover 1b is secured to the protector main body 1a. The protector 1 having a configuration in which the cover 1b is locked to the protector body 1a by being locked in the lock hole 1e is shown.
Further, an opening (notch) 1f for leading the branch wire w to the outside is provided on the side surface of the protector body 1A in order to branch the partial wire w of the wire harness W / H accommodated in the protector 1. It is provided at the branch position (Patent Document 1).

On the other hand, when the protector that accommodates the wire harness is used in a straight portion such as a rocker portion of an automobile floor panel, an protector made of an extruded product is suitable from the viewpoint of mold cost. However, since the opening 1f for branching as in Patent Document 1 cannot be formed at the branch position by extrusion molding, it is necessary to provide the opening 1f by secondary processing such as punching after extrusion molding. There arises a problem that the manufacturing cost increases due to the secondary processing.
Further, when the branch position of the wire harness changes, the position of the opening 1f itself must be changed, and the branch position is changed after the opening 1f is once formed by punching or the like. There is also a problem that is not easy.
