JPH0779518A - Fixing metal for flat cable - Google Patents

Abstract

PURPOSE:To provide a fixing metal for a flat cable which accommodates bending or elongation of the flat cable sufficiently when a plurality of laminated flat cables are fixed while realizing rigid fixing. CONSTITUTION:The metal 3 for fixing a plurality of laminated flat cables 1 to a panel 2 comprises a head part 4, a leg part 5 and a counter boring part 7, wherein a flat cable 1 is clamped between the leg part 5 and the counter boring part 7. The leg part 5 is provided, at the intermediate part thereof, with a top part 5a coming into contact with the flat cable 1. Since the end part 5b comes into contact with the fixing face of the panel 2 and elastic deformation takes place from a state shown by a dot line to a state shown by a solid line when the flat cable 1 is clamped, the flat cable 1 is secured rigidly by the recovery force.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable fixing device used for assembling a flexible flat cable to, for example, a vehicle body of an automobile.

[0002]

2. Description of the Related Art Conventionally, as a means for fixing a flat cable, a clip-shaped means as disclosed in, for example, Japanese Utility Model Laid-Open No. 63-2652, Shokai 63.
A method of inserting a locking member into an engaging member attached to a panel as disclosed in Japanese Patent Laid-Open No. 93715 or a combination of a holding plate as shown in Japanese Utility Model Laid-Open No. 61-44888. Various means are known. In addition, fixing by taping, stapler or the like is also performed.

[0003]

Such a conventional flat cable fixing means has insufficient followability to bending or stretching when, for example, assembling a plurality of laminated flat cables to a vehicle body of an automobile. However, there are problems that it is difficult to perform the assembling work, that there are variations among workers, or that the function of preventing misalignment between layers in the assembled state is insufficient.

The object of the present invention is to solve the above-mentioned problems,
To provide a fixture for a flat cable capable of sufficiently following bending or stretching when assembling a plurality of laminated flat cables, and reliably preventing interlayer displacement in the assembled state. Especially.

[0005]

A fixture for a flat cable according to the present invention for achieving the above object allows a certain degree of misalignment between layers when assembling a plurality of laminated flat cables. In the assembled state, the flat cable is firmly tightened.

[0006]

The flat cable fixing device having the above-described structure allows a certain degree of gap between layers when assembling a plurality of laminated flat cables, and firmly fixes the flat cable after once assembling. To be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on the illustrated embodiments. FIG. 1 shows a first embodiment of a fixture for a flat cable according to the present invention, and shows a state in which a plurality of laminated flat cables 1 are fixed to a panel 2 for attachment by a fixture 3. The fixture 3 is made of an elastic material such as a synthetic resin material or a metal, and is attached to the mounting hole 2 of the panel 2.
a head 4 that is forcibly fitted to a and a plurality of pieces that extend inward from the inside of the step 4a at the lower part of the head 4 and that have a top portion 5a and an end portion 5b in a substantially V shape. Book legs 5 and head 4
Has a seat surface 7 formed at an end of a rod-shaped connecting portion 6 extending from the inner center of the flat cable 1 and the flat cable 1 is sandwiched between the seat surface 7 and the leg 5. There is.

Since the head portion 4 has a space 8 inside, the head portion 4 is recessed so that the space 8 is small, and the head portion 4 is inserted into the mounting hole 1a provided in the flat cable 1, and the panel 2 is further lowered from below. It is possible to fit by fitting the mounting hole 2a, and after fitting, it is restored to its original shape by elasticity and the step portion 4
The state a is locked to the peripheral edge of the mounting hole 2a. The top portion 5a of the leg portion 5 is in contact with the flat cable 1, the end portion 5b is in contact with the back surface of the panel 2, and the flat cable 1 is sandwiched between the original shape shown by the dotted line and the compressed and expanded shape shown by the solid line. Elastically deforms.

Therefore, when the fixture 3 is assembled to the panel 2, the flat cables 1 that are stacked can be displaced to some extent from each other by providing a margin in the mounting hole 1a. Although the flat cable 1 can be sufficiently followed by bending and stretching, the flat cable 1 is strongly pressed against the seat surface 7 by the elasticity of the legs 5 in the assembled state, so that the interlayer displacement is prevented.

FIG. 2 shows a second embodiment. In this case, an appropriate number of cuts or convex pieces are provided on the outer edge portion of the flat cable 11, and a step portion 12a is provided on one side and a taper portion 12b is provided on the other side.
Formed on the inner surface of the fixture 13 made of a synthetic resin material or the like.
The retaining claw 14 that is retained by a is elastically deformable to the support piece 1
5, the fixture 13 is slidable with respect to the flat cable 11 in the direction of arrow A, and is reversely stopped in the opposite direction by the engagement of the engagement piece 12 and the engagement claw 14. is there.

Therefore, when fixing a plurality of laminated flat cables 11, it is possible to sufficiently follow bending and elongation, and it is possible to prevent interlayer displacement in the fixed state. Instead of the locking piece 12, the flat cable 11 may be provided with a locking hole 16 as shown in FIG.

FIG. 4 shows a third embodiment, in which a plurality of laminated flat cables 21 are fixed by bushes 24 made of an elastic material such as rubber and having flanges 23 provided at both ends of a shaft portion 22. An example is shown.

In this case, the elasticity of the bush 22 itself is used to attach the shaft portion 22 to the mounting hole 21a of the flat cable 21.
Since the flat cable 21 is sandwiched by the flange 23 and the flat cable 21 is sandwiched by the flange 23, the same effect as in the first embodiment can be obtained, so that the follow-up fixation is possible.

In the fourth embodiment shown in FIG. 5, in order to fix the flat cable 31, a hair clip-shaped fixture 33 having a reversible curved portion 32 near the center is used.

In this case, the fixture 33 is attached to the vehicle body with the flat cable 31 held at a predetermined position,
For example, the curved portion 32 is sandwiched between the panel and the trim,
By being inverted as shown by the dotted line 32 ', the flat cable 31 can be firmly fixed.

In this case as well, the flat cables 31 can be displaced from each other to some extent during assembly, but once assembled, interlayer displacement is prevented.

[0017]

As described above, the fixture for a flat cable according to the present invention can fix the flat cable by sufficiently following the bending and stretching of the flat cable when assembling a plurality of laminated flat cables. Therefore, the assembling work is easy, and the variation in the work can be reduced. Further, the pattern design of the flat cable is facilitated, and moreover, it is possible to cope with the displacement between layers of the flat cable and to firmly fix the flat cable.
