The state of being fixed by and protected by the lid 1 and the main body 2 is obtained. (See FIG. 5 (b)) (Problems to be solved by the invention) However, in the above-described conventional protector,
When the wire harness 5 is housed in the main body 2 and the lid 1 is mounted, a considerable force is required to press the lid 1 and thus the workability is inferior while the lid 1 is attached to the main body 2 Once attached to the wire harness 5, the wire harness 5 is strongly fixed by the ribs 3, 4, 4'and axial movement is prohibited, so that dimensional accuracy is strictly required, or the wire harness 5 is finely adjusted in the axial direction. There was a problem when trying to do so.

That is, if it is absolutely necessary to adjust the position of the wire harness 5, the troublesome work of releasing the locking mechanism of the lid 1 and removing the lid 1 from the main body 2 again is required.

Then, the subject of this invention is solving the problem in the fixing structure of the said conventional wire harness to the protector.

Therefore, an object of the present invention is to provide a protector for a wire harness that can easily perform a fixing operation of the wire harness and a position adjustment of the wire harness after the wire harness is incorporated into the protector, and further improve fixing reliability. To provide a fixed structure.

In a protector in which wire harness fixing means are provided on the bottom of the main body and the inner surface of the lid so as to be displaced from each other in the longitudinal direction, at least one of the fixing means is a member provided on the main body and / or the lid. It consists of a stop hole and a locking body that is separate from the protector. First, the wire harness is stored in the main body, then the lid is mounted on the main body, and then the locking body of the fixing means is locked. It is characterized by being attached to the section.

(Operation) The present invention allows the wire harness to be moved in the axial direction of the protector even after the wire harness is housed in the body of the protector and the lid is attached, unless the fixing means is used. The wire harness can be fixed by finely adjusting the wire harness and then fitting the locking body of the fixing means into the locking hole.

Further, since the wire harness fixing means may be applied after the cover body of the protector is attached to the main body, the work of attaching the cover body does not require a large force and the workability can be improved.

Moreover, when applying the wire harness fixing means, it is sufficient to push the locking body into the locking hole which constitutes the fixing means, and the locking body has a small area, and can be easily locked by the sliding force of the clip, for example. Since it fits into the hole, it does not require a large force for fixing the wire harness.

Therefore, according to the structure for fixing the wire harness to the protector of the present invention, the position adjustment of the wire harness and the fixing work of the wire harness after the wire harness is incorporated into the protector can be easily performed.

(Embodiment) An embodiment of a structure for fixing a wire harness to a protector according to the present invention will be described below in detail with reference to the drawings.

In the first embodiment shown in FIGS. 1A to 1C, the protector 10 of the present invention comprises a main body 20 having a U-shaped cross section, and a lid 30 formed to cover the main body 20. , The main body
A wire harness fixing means E is provided on the bottom of 20 and the inner surface of the lid 30.

The wire harness fixing means E is different from the ribs 21A and 21B projectingly provided in the bottom width direction on the main body 20 side, the locking hole 31 provided at the center of the lid 30 side width direction, and the protector 10. It is composed of a body locking body (clip) 32.

In the above structure, the ribs 21A and 21B on the main body 20 side and the lid body
The locking hole 31 on the 30 side is arranged so that the locking hole 31 is located at the center of the ribs 21A and 21B.

The work of housing and fixing the wire harness 40 in the protector 10 is performed as follows.

First, with the clip 32 not inserted into the locking hole 31 of the lid body 30, the lid body 30 is opened, the wire harness 40 is housed in the main body 20, and then, as shown in FIG. 1 (b). The lid 30 is attached to the main body 20.

In this state, since the fixing means E does not act, the wire harness 40 can move in the axial direction, and the lid body 30 can be moved.
The fine adjustment of the position of the wire harness 40 can be easily performed while being attached to the wire harness 20 as needed.

Thus, after securely positioning the wire harness 40,
When the clip 32 is pushed into the locking hole 31 of the lid body 30, the clip 32 and the locking hole 31 are firmly fitted and the tip of the clip 32 presses the wire harness 40 as shown in FIG. 1 (c). Therefore, the structure for fixing the wire harness 40 to the protector 10 is completed.

In this fixing structure of the wire harness to the protector, the ribs 21A and 21B on the main body 20 side and the clip 32 on the lid 30 side are provided.
Both of them press the wire harness 40, and excellent fixing reliability is obtained.

Next, in the second embodiment shown in FIG. 2, a locking hole 22 and a clip 23 are provided on the body 20 side of the protector 10, and a rib is provided on the lid 30 side.
The point that 33A and 33B are provided is different from the first embodiment described above.

Therefore, in order to fix the wire harness 40 in the second embodiment, after the wire harness 40 is housed in the main body 20 and the lid 30 is mounted, and then the position of the wire harness 40 is adjusted as necessary, Clip 23 in the locking hole 22 on the body 20 side
It suffices if they are fitted together, and thereby the same effect as that of the above-described first embodiment can be obtained.

In the third embodiment shown in FIG. 3, the protector 10 has locking holes 22A and 22B and clips 23A and 23B on the body 20 side, and a locking hole 31 and clip 32 on the lid 30 side. The provision of the wire harness fixing means is different from the above-described first and third embodiments.

Therefore, in order to fix the wire harness 40 in the third embodiment, the wire harness fixing means E of either the main body 20 or the lid 30 is not inserted, or the clip is not inserted at all. By accommodating the harness 40 in the main body 20 and mounting the lid 30, and then adjusting the position of the wire harness 40 as necessary, by fitting the remaining clips or all the clips into the locking holes, It is possible to obtain the same wire harness fixing effect as that of the first and second embodiments described above.

Further, the fourth embodiment shown in FIG. 4 is the same as the first embodiment described above, except that the clip 32 on the lid 30 side is provided on the panel 50 for mounting the protector 10. 1
This is different from the embodiment.

In this way, if the clip 32 is integrated with the panel 50, the wire harness 40 is stored, and after adjusting its position as necessary, the protector 10 is simply pressed against the panel 50, and the The fixing and the mounting and fixing of the protector 10 to the panel 50 can be performed at the same time, and the work of incorporating the wire harness 40 can be further rationalized.

Further, in the above-mentioned fourth embodiment, the clip 32 on the lid 30 side is provided integrally with the panel 50 for attaching the protector 10, but this has a shape in which two clips are integrated back to back. The protector 10 can be easily attached to the panel 50 by using a clip (not shown). In this case, it goes without saying that the panel 50 is provided with a clip mounting hole in advance.

In addition, in each of the above-described embodiments, the locking body as the wire harness fixing means is described as a clip, but the invention is not limited to this. For example, a bracket or a screwing means may be used instead of the clip. Of course, you can also do it.

[Effects of the Invention] Since the present invention is configured as described above, the wire harness is housed in the body of the protector, even after the lid is attached, unless the fixing means is used. It is possible to fix the wire harness by finely adjusting the wire harness and then fitting the locking body constituting the fixing means into the locking hole.

Further, since the wire harness fixing means may be attached after the lid of the protector is attached to the main body, a large force is not required for attaching the lid, and workability can be greatly improved.

Moreover, when attaching the wire harness fixing means, it suffices to push the locking body into the locking hole which constitutes the fixing means, and the locking body has a small area and can be easily engaged by the sliding force of the clip, for example. It can be fitted into the stop hole and does not require a large amount of force to fix the wire harness.

Therefore, according to the structure for fixing the wire harness to the protector of the present invention, the position adjustment of the wire harness and the fixing work of the wire harness after the wire harness is incorporated into the protector can be easily performed.
