Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for holding and fixing a flat plate material, for example, a structure capable of holding and fixing a flat plate material such as a flexible printed circuit in a mounting hole with one touch.

[0002]

2. Description of the Related Art Conventionally, in order to connect electric devices, for example, a wire harness of a wire bundle is routed and held and fixed in a vehicle, and a copper plate is used instead of the wire harness. Flexible printed circuit (hereinafter referred to as F
Also called PC. ) Has also been used. In addition,
A flat material such as an FPC includes a flexible flat cable (hereinafter, referred to as an FPC) in which a plurality of electric wires are arranged in a plate shape.
Also called FC. ), But the following describes the case of FPC as an example.

[0003] This FPC also needs to be held and fixed to the vehicle similarly to the wire harness.
For example, as shown in FIG. 4, the area S without the conductive pattern P is aligned with the mounting hole H formed in the vehicle panel.
In general, a through-hole h is formed in the region S, and the through-hole h and the mounting hole H are aligned with each other and screwed with a bolt B.

[0004]

However, in such a conventional FPC made of a flat plate material, when the FPC is held and fixed to a vehicle, a state in which the through hole h is aligned with the mounting hole H of the vehicle panel. It is necessary to insert the bolt B and screw it in while maintaining it. In the actual machine, the through hole h may be slightly displaced from the mounting hole H, and there is a problem that the burden of the screwing work is large.

Accordingly, an object of the present invention is to realize holding and fixing of a flat plate material by means other than screwing, thereby facilitating the work of holding and fixing the flat plate material.

[0006]

SUMMARY OF THE INVENTION The invention for solving the above-mentioned problem is a structure in which a flat plate material is held and fixed by a holding fixture at a position where an attachment hole is opened, and the flat plate material is held at a separated position. While forming a plurality of areas for holding and fixing, while forming a pair of through-holes that open at adjacent positions in each of the areas, the holding fixture, the substrate formed into a shape over the area for holding and fixing, A clip portion provided on one surface side of the substrate and attached to the mounting hole, a band portion formed on the substrate so as to be able to penetrate from one side to the other through the through hole of the flat plate material and to be rewound; And a locking portion formed on the substrate so as to lock engagement with and return to the band portion that has been pierced and rewound.

According to the present invention, the band portion formed on the substrate of the holding fixture is inserted into one of the pair of through-holes in each of the holding and fixing regions of the flat plate material, and is engaged with the pull-out locking portion from the other. By locking, the band portion wound back by the through hole can be bound and fixed, and the flat plate material can be held at a plurality of locations. Can be fixed to a panel of a vehicle or the like in which is formed. Therefore, it is possible to hold and fix the flat plate material such as the FPC by separately performing the holding by the band portion and the fixing by the clip portion without screwing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of a holding and fixing structure for a flat plate material according to the present invention. In the present embodiment, the same components described in the above-described conventional example will be described with the same reference numerals.

In FIG. 1, a holding fixture 10 is an FPC (a flat plate material) punched out after a conductive pattern P made of a copper plate or a metal foil for connecting electrical devices shown in FIG. ) Is held and fixed, for example, at the position of a mounting hole H shown in FIG.

The holding fixture 10 includes a substrate 11 formed to have a length approximately equal to the width of the FPC (a length extending over a holding and fixing region S described later), and an arrow-shaped portion provided on one surface of the substrate 11. When the clip 12a is inserted into the mounting hole H from the head, the clip portion 12 is elastically deformed and then elastically returns to engage the edge of the mounting hole H so that the clip portion 12 can be mounted and fixed.
An elastic piece 13 provided between the clip portion 12 and the substrate 11 and formed into a bowl shape so as to sandwich the periphery of the mounting hole H between the clip portion 12 and the substrate 11;
A band portion 14 engraved with an engagement groove 14a on one surface side thereof and wound around the mounting member;
And an engaging claw (not shown) formed therein and engaged with the engaging groove 14a to limit the movement in the returning direction by integrally forming the engaging claw 14a. I have.

In the FPC, holding and fixing regions S without the conductive patterns P are formed at both sides in the extending direction adjacent to the conductive patterns P, and each of the regions S A pair of through holes h that open adjacently
1 and h2 are formed. When the holding fixture 10 is brought into surface contact with the other surface of the substrate 11 in a posture orthogonal to the extending direction, the FPC is formed in the holding and fixing region S. Are designed so that the band portion 14 and the locking portion 15 are located on both sides.

Therefore, as shown in FIG. 3, the holding fixture 10 allows the band portion 14 to penetrate from one of the through holes h1 and h2 formed in each of the holding and fixing regions S of the FPC to the other. The band portion 14 and the locking portion 15 can be held while restricting rotation of a plurality of portions of the holding and fixing region S while being held by the rewinding locking portion 15. The clip portion 12 erected on one surface side is inserted into the mounting hole H, and the elastic piece 13 is inserted.
The vehicle panel can be sandwiched between and fixed with one touch.

As described above, in this embodiment, the FPC is held by the band portion 14 and the locking portion 15 at a plurality of positions in the holding and fixing region S, and the mounting hole H is formed by the clip portion 12 and the elastic piece 13. The fixing of the FPC to the formation position can be performed separately, and the FPC can be easily held and fixed. Therefore, without using screws
Can be easily held and fixed.

In this embodiment, an FPC will be described as an example. However, it is needless to say that the present invention is not limited to this. For example, a flat plate material such as an FFC can be similarly held and fixed.

The holding and fixing regions S of the FPC are formed at two places on both sides, but are not limited thereto. For example, a region without the conductive pattern P is formed at the center of the FPC to form a pair of regions. Needless to say, a through hole may be formed, and the substrate and the band portion of the holding fixture may be formed according to the arrangement and the number of the through hole.

[0016]

According to the present invention, a plurality of flat plate materials can be formed by rewinding a band formed on a substrate of a holding fixture by a through hole in a corresponding holding and fixing region and engaging and locking the locking portion. It can be held in place and can be fixed by attaching the clip portion of the substrate to the attachment hole. Therefore, the flat plate material can be easily held and fixed without screwing.
