DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness protector for accommodating and protecting a plurality of wire harnesses, and more particularly, to a structure for enabling three-dimensional wiring of a wire harness in the protector.

[0002]

2. Description of the Related Art A conventional wire harness protector disclosed, for example, in Japanese Utility Model Laid-Open Publication No. Hei 2-142215 will be described with reference to FIGS. 6 and 7. As shown in FIG. It comprises a protector body 61 formed in a letter shape and a cover 62 put on the protector body 61. Further, the protector main body 61 and the cover 62 are provided with tongue pieces 63 extending in the wiring direction of the wire harness 70 at the ends on the opening side in the wiring harness wiring direction. Then, in a state where the cover 62 is detached from the protector main body 61, the wire harness 70 is stored in the protector main body 61, and then the cover 62 is covered. Then, tie tape 7
2, the tongue pieces 63 of the protector body 61 and the cover 62 and the converged wire harness 70 are simultaneously wound. As a result, the protector 60 can fix the wire harness 70 while preventing displacement, and at the same time, firmly fixes the protector body to the cover.

[0003]

However, since the wire harness 70 is fixed to the protector main body 61 and the tongue piece 63 of the cover 62 by the binding tape 72, the plurality of wire harnesses 70 are connected to the opening end in the wiring harness wiring direction. However, there is a problem that it is impossible to perform a three-dimensional arrangement such as a multi-stage arrangement in a part. In addition, since the wire harness 70 is fixed using the binding tape 72, a great deal of time is required for removing the wire harness 70 from the protector 60, for example, for maintenance work.

[0004] The present invention has been made in view of the above circumstances,
The aim is to provide a protector that enables the wiring harness to be routed, protects the wire harness, and secures the wire harness to the protector body, and is easy to handle in maintenance work and the like. I do.

[0005]

According to a first aspect of the present invention, there is provided a wire harness protector having a three-dimensional housing having an upper opening for accommodating the wire harness. A protector body disposed at least in two stages, a cover fitted to the protector body to close the upper opening surface, and locked to the protector body and the cover with the wire harness inserted therethrough. Accordingly, the wire harness is held in each of the housing portions of the protector main body, and the wire harness is detachably disposed between the three-dimensionally arranged housing portions so that the wire holding device can be locked. A spacer for attaching an electric wire holding means.

[0006] The wire holding means is locked by the protector body and the cover with the wire harness inserted therethrough, so that the wire harness is held in each accommodating portion of the protector body. In addition, since the wire holding means mounting spacer is removably disposed between the three-dimensionally arranged receiving portions, the wire holding means can be three-dimensionally routed, and the wire holding means can be protected. Can be locked to the body. Thus, the wire harness is securely held in each of the housing portions of the protector body via the wire holding means.

According to a second aspect of the present invention, there is provided the wire harness protector according to the first aspect, wherein the wire holding means has an annular recess formed on a peripheral surface thereof along a longitudinal direction. The protector body, the cover, and the spacer for attaching the wire holding means are provided with tube locking ribs which can be engaged with the annular concave portions of the wire holding means, respectively. The means may be characterized in that the wire harness is held in each accommodating portion of the protector body by engaging the tube locking rib in the annular concave portion with the wire harness inserted. .

[0008] The wire holding means comprising a flexible tube,
With the wire harness inserted, the tube locking ribs provided on the protector body, the cover, and the spacer for attaching the wire holding means are respectively engaged with the annular concave portions. Thereby, the flexible tube is attached to the protector body and the cover at the end on the opening side in the wiring harness wiring direction. Therefore, the wire harness is securely held in each housing section of the protector body via the flexible tube.
