[0002]

2. Description of the Related Art A wire harness of this type is required to be able to be bent three-dimensionally in accordance with the shape of a vehicle wiring position. As a protector that meets the above-mentioned demands, an actual Kaihei 1-150411 is proposed.
As shown in (A) and (B), six gutter-shaped main bodies 1 each having a lid 2 are connected in parallel in two rows by a thin film portion 3 so that the thin film portion 3 can be bent. There is.

In the protector 4, the wire harness W / H is inserted through the main body 1 and the lid 2 is closed, as shown in FIG.
As shown in FIG. 4, the protector 4 is attached to a required portion of the vehicle body in a state of being bent by the thin film portion 3 according to the wiring position of the protector 4.

[0004]

However, in the protector 4 described above, two main bodies 1 are arranged side by side, and three thin film portions 3 having a wide width and arranged in two rows are connected to each other in the longitudinal direction. Therefore, in each thin film portion 3, as shown in FIG. 6 (B), it is possible to refract only upward or downward, and there is a drawback that it is difficult to refract or twist in the lateral direction.

As described above, in the structure in which the main body 1 can be bent only in the vertical direction and three main bodies 1 are provided in series in the lengthwise direction through the thin film portion 3, as shown in FIG. It can be attached along the convex portion 5 only when there is one convex portion 5 at the position, but when it is necessary to bend the wire harness three-dimensionally and route it,
If two convex parts are located close to each other, the protector 4
I can't handle it. That is, the usable position of the protector 4 is limited, and if the shape of the wiring position is different, a plurality of protectors are required, which results in high cost.

The present invention has been made in view of the above-mentioned drawbacks, and can be bent vertically and horizontally and can be twisted, and the shape of the gutter-shaped body and the number of connecting portions between them can be arbitrarily set. It is an object of the present invention to provide a protector for wireness that can be applied to a rope position.

[0007]

To achieve the above object, the present invention provides a protector made of resin for accommodating and protecting a wire harness, the protector being provided between a plurality of gutter-shaped main bodies and the main bodies. , A constricted portion that connects the bottom wall portions of the adjacent main bodies and reduces the width and thickness to enable vertical bending and twisting, and corresponds to the shape of the wiring position of the wire harness. (EN) Provided is a wire harness protector configured to bend or twist in a required direction at a constricted portion.

A body in which the main body and the constricted portion are alternately continuous is molded in advance, and is cut at a position having a required number of the main body and the constricted portion in accordance with the shape of the wiring position to form one protector. May be provided.

In the above-mentioned protector, the tape winding fixing portion is provided so as to project from the tip of the bottom wall of the main body at both ends in the lengthwise direction, and the wire harness is wound on the tape winding fixing portion and fixed to the protector. Further, it is preferable that a lid for closing the upper end opening of each of the main bodies is provided integrally or separately. In addition,
The outer peripheral surface of the main body may be tape-wound after the wire harness is inserted into the main body without providing the lid. Further, a clip for locking the vehicle body is provided on the outer surface of each of the main bodies so as to project therefrom.

[0010]

According to the wire harness protector of the present invention, since the constricted portion has a small width and a small thickness, it can be bent in the vertical direction and can be twisted in the horizontal direction or in an arbitrary inclined direction. Therefore, the protector can be along the wiring position by bending or twisting the necked portion between the main bodies according to the shape of the wiring position of the wire harness. Further, the numbers of the main body and the constricted portion are not limited, and the number can be set arbitrarily according to the shape of the wiring position, so that the usable range is widened. For example, like the conventional example of FIG. 6, after being bent in a convex shape, it can be twisted in the horizontal direction, and in particular, it can be suitably used at a position where the shape of the installation position changes intricately.

Further, by fixing the wire harness by tape winding on the tape winding fixing portion projecting from the main body at both ends in the length direction, the wire harness can be fixed along the entire length of the protector. In that case, if the lid that closes the opening of the main body is not provided, wrap the tape around the main body containing the wire harness to prevent the electric wire from protruding from the main body, and to protect the deformer more securely. The harness can be routed.

Further, after the wire harness is inserted through the protector, the upper end opening of each body is closed with a lid, so that the wire harness can be easily prevented from jumping out from each body by one-touch operation.

Furthermore, when a clip for locking the vehicle body is provided on the outer surface of each main body so as to be locked to the vehicle body, the shape of the protector which is deformed by being bent or twisted at the constricted portion can be fixed.
