Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible flat cable used in a vehicle such as an automobile, and a bending auxiliary plate attached to the flexible flat cable to follow the bending operation of the flexible flat cable. Related to the support structure.

[0002]

2. Description of the Related Art Conventionally, a supporting structure of this type is shown in FIG.
9 is known. That is, 1 indicates a flexible flat cable, and FIG.
In, the two are stacked to form the circuit body 2. The circuit body 2 is, for example, interposed between a vehicle body of a vehicle (not shown) and a slide door slidably attached to the vehicle body, and is arranged in a power supply device capable of supplying power from the vehicle body to the slide door. It is designed to move while bending as it is opened and closed. When the circuit body 2 moves while bending, the flexibility of the flexible flat cables 1 and 1 may cause the circuit body 2 to hang down. A follow-up bending assist plate 3 is provided.

The bending assisting plate 3 is formed with a plurality of grooves 3b, 3b, ... Which face each other on both side edge portions 3a, 3a of the bending assisting plate 3, and a retaining thread is provided for each pair of grooves 3b, 3b. 4 is wound to support the circuit body 2. Also, both ends of the bending assisting plate 3 in the longitudinal direction (not shown) are
It is attached to a fixed portion of a vehicle (not shown) by appropriate fixing means.

[0004]

In the above-mentioned prior art, the flexible flat cables 1, 1 and the circuit body 2 and the bending assisting plate 3 are arranged so that the circuit body 2 can be smoothly bent. They are not glued or fixed together. That is, as shown in FIG.
2 pieces of the flexible flat cable 1'are stacked (not fixed) with their ends fitted exactly together, and then, as shown in FIG.
As shown in FIG. 1, when bent at the intermediate portion, both ends of the three flexible flat cables 1 ′ are displaced from each other by ΔL due to the bending, and if the displacement is not allowed, the circuit body 2 This is because the bending motion of is not performed smoothly.

Therefore, at present, as shown in FIG. 19, a structure for supporting the circuit body 2 on the bending assisting plate 3 by using the retaining thread 4 is adopted. Further, as shown in FIG. 22, the circuit body 2 is placed on the bending assisting plate 3, and the pair of grooves 3b,
A support structure in which the clip 5 is externally fitted every 3b is also adopted.

However, according to the above support structure, the retaining thread 4 (see FIG. 19) and the clip 5 (see FIG. 22), which are separate members, must be attached to each of the grooves 3b and 3b forming a pair. There is a problem that the number of work steps for assembling is very large, which affects the entire work.

Further, when the stopper thread 4 (see FIG. 19) is used, unless it is always wound with a constant winding force, a portion where the stopper thread 4 is loosened is generated, and the stopper thread 4 comes off from the groove 3b. There is also a problem that it ends up. In addition, if the wrapping force is large, the bending of the bending assisting plate 3 as shown in FIG. 19 becomes large, which may affect the bending operation.

Further, since the circuit body 2 and the bending assisting plate 3 and the like are not fixed to each other, there is a problem that the retaining thread 4 and the like are difficult to assemble. Further, it is very difficult to control whether or not the bending motion is impaired, which makes the work more complicated.

In order to solve the above-mentioned problems, it is an object of the present invention to provide a support structure for a flexible flat cable which allows a flexible flat cable to be easily and quickly attached to a bending assist plate. To do.
