Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure for a wiring harness for a vehicle, and more particularly to a method for preventing the wiring harness from interfering with a component mounted on the vehicle by a simple method.

[0002]

2. Description of the Related Art Wire harnesses routed to automobiles are designed on routes that do not interfere with other parts mounted on the automobile. However, after the wire harness is assembled to the vehicle body at the automobile assembly line, it is assembled to the vehicle body. In some cases, interference may occur with parts that are installed or parts that are assembled at a dealer.

For example, in the case shown in FIG. 7, the wire harness W / H routed along the front surface of the vehicle body panel 1 is located at the position of the clip holes 2, 3, and 4 provided in the vehicle body panel 1. Clips 5A and 5
B and 5C are inserted and locked, and are routed along the vehicle body panel 1. In this wiring harness W / H wiring configuration,
The wire harness W / in the X section between the clips 5A and 5B
H-1 is laid in a straight line, and the wire harness W / H-2 in the section Y between the clips 5B and 5C is laid in a curved shape.

[0004] When a retrofit component 6 shown in FIG. 9 is attached to the vehicle body panel 1 with respect to the wire harness W / H arranged on the vehicle body panel 1 as described above, the component 6
The bracket 6a protruding upward hits the wire harness W / H-1 in the straight section X routed upward, causing interference.

[0005]

Therefore, the component 6 cannot be mounted. However, if the component 6 is forcibly mounted, the wire harness W / H comes into contact, and the wire harness W / H is contacted.
/ H may be broken.

In such a case, the wiring harness W / H may be moved upward so that the wiring harness W / H does not interfere with the component 6, but the projecting portion 1 a of the vehicle body panel 1 is located above the clip holes 3 and 4. , 1b, and the clip holes 3, 4 cannot be set upward.

[0007] In addition to the above-described situation, the wire harness may be prevented from interfering with other parts to cause disconnection or the like.
In general, it is passed through a protector made of a resin molded product. However, since the protector is a dedicated part having a shape corresponding to a wiring path of a wire harness and is molded by a metal mold, the cost is very high. Further, if the configuration is such that the protector is protected, a space for installing the protector is required, and a large space is required as compared with a wiring space for the wiring harness.

The present invention has been made in view of the above problems, and has as its object to provide a wiring harness routing structure that can easily avoid interference with components without using a protector.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a method of attaching a resin rod to a required section of a wire harness along a longitudinal direction, and fixing both ends of the resin rod together with the wire harness to a vehicle body. The distance between the clips on both sides is set to be longer than the linear dimension between the clip holes drilled on the vehicle body, and the clips on both sides are inserted into the clip holes on the vehicle body panel when the vehicle is mounted. The wire harness routing structure is characterized in that the resin rod is bent in an arch shape by stopping the wire harness to prevent the wire harness from interfering with other components.

That is, in the wiring route of the wire harness, if the wiring harness is laid out in a straight line, causing interference with other components, the clip to be attached to the wire harness with the section interfering with the other components interposed therebetween. It is fixed to the wire harness and the resin bar at a position where a required dimension is opened in a direction away from the hole position. With this configuration, when the vehicle body is mounted, the clip on both sides becomes a fulcrum, and the resin bar curves neatly into an arch shape, and the wire harness also curves with the curve of the resin bar, thereby preventing interference with other components.

The above-mentioned resin rod is fixed to the wire harness by winding the tape together with the electric wire group of the wire harness. Alternatively, a resin rod is disposed at an outer peripheral position of a wire harness in which a group of electric wires is wound with a tape, and the resin rod and the wire harness are further fixed by winding a tape.

Since the clip serves as a bending fulcrum of the resin rod, it must be firmly fixed to the resin rod and the wire harness. Therefore, a band-type clip is preferably used.

The section adjacent to the section in which the wire harness is bent together with the resin rod is a straight section in which the wiring harness is routed linearly in the direction opposite to the bending direction. The wire harness is pulled to bend in a required direction, and the clip hole provided in the vehicle body panel is a round hole so that the clip can be rotated during bending.

As described above, when the wire harness in the section to be bent is pulled in a straight line opposite to the bending direction in the section adjacent to the section to be bent, the bending in the required direction may be caused. it can. That is, when it is desired to bend upward, by arranging at least one section adjacent to the section downward linearly, the wire harness in the section to be bent upward can be reliably bent upward. . Conversely, when the wire harness of the adjacent section is laid straight up, it can be bent downward.

Further, the clip hole on the vehicle body panel side for inserting and locking the clip serving as a fulcrum to be bent is rotated as the resin rod and the wire harness are bent. I have. This round hole is applied when the section adjacent to the section to be bent is set to be short, and the section is bent in a required direction by pulling the wire harness in the adjacent section as described above.

Further, the clip hole at a position serving as a fulcrum to be bent may be a long hole having a required angle, and the wire harness may be directed in a required direction when the clip is locked in the clip hole. In this case, it is not necessary to set the adjacent section as a straight section and to pull the wire harness in the direction of bending.

As described above, when the resin rod is attached to the wire harness and the dimension between the clip attaching positions is set longer than the linear dimension between the clip holes, when the clip is locked in the clip hole, the resin rod and the The wire harness can be bent in a required direction, and this bending can easily eliminate interference with other components.
