Abstract

PURPOSE: To stabilize the bundled state of a plurality of flat cables and eliminate shifting and deformation of products by forming common parts with similar shapes in a plurality of respective flat cables and bundling the common parts. CONSTITUTION: A common part 18 is formed in the middle part of a flat cable which is provided with a conductor 12, an insulating film 13, a connector 14, etc. In the same way, a common part 19 is formed also in a flat cable 16 and a common part 17 is formed also in a flat cable and the common parts 17-18 have similar shapes and the wide size is made to be the same. Consequently, in the case these cables and gathered and the common parts 17-19 are bundled by a bundling band, no void is formed and the bundling state is stabilized and shifting and deformation occurrence of products are prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable which is used, for example, in a car interior wiring of an automobile or the like, and in particular, a plurality of sheets are laminated and bound to be used.

[0002]

2. Description of the Related Art Conventionally, a flat cable having a foil-like conductor, which has been used for in-vehicle wiring of an automobile or the like, is often used by laminating a plurality of sheets, and the laminated state is always stable. Must be held. For this reason, the laminated flat cables are used by being wound with an adhesive tape such as a vinyl tape or being bound by a clip band.

[0003]

However, a plurality of flat cables often have different widths, for example, and when flat cables 1 and 2 are stacked as shown in FIG. 5, an intermediate portion to be bound. The width is different in. Here, when the middle portions of the flat cables 1 and 2 are bound by the clip band 3, a gap D as shown in FIG. 6 is generated.

In the gap D, the flat cables 2 and 3 may be displaced from each other, so that the flat cables 1 and 2 are displaced from each other as shown in FIG. 7, and are connected to, for example, the conductor of the terminal portion. The distance between the connectors 4 is shown in FIG.
7 is moved from the regular distance W shown in FIG. 6 to W ′ shown in FIG.

The object of the present invention is to solve the above problems,
An object of the present invention is to provide a flat cable that can be stably held without deviation in a bound state by forming the outer shape of the common part of the intermediate portions having similar shapes in advance to have the same shape.

[0006]

A flat cable according to the present invention for achieving the above object is a flat cable of a plurality of types having a common portion having a partially similar shape in an intermediate portion. It is characterized in that it is formed in substantially the same shape in advance, and a stable bound state is maintained by stacking and binding the common portions.

[0007]

In the flat cable having the above-described structure, the outer shape of the common portion of the flat cable having a similar shape to the intermediate portion is formed to have substantially the same shape in advance, and when the plurality of flat cables are stacked and used, the same shape It binds in the shape part.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 shows a plan view of a first flat cable. In this first flat cable 11, a plurality of conductors 12 made of metal foil are wired along a pattern and sandwiched by an insulating film 13. A connector 14 is connected to the end of the conductor 12.

Further, FIG. 2 shows a second flat cable 15
FIG. 3 shows the third flat cable 16. These second and third flat cables 15, 16
In the same manner, the conductor 12 is sandwiched between the insulating films 13, and the connector 14 is attached to the end of the conductor 12 as in the first flat cable 11.

And the flat cables 11, 15, 16
In, the width of the intermediate binding portions 17, 18, and 19 is the same.

In this way, the outer shapes of the common parts 17, 18, and 19 of the flat cables 11, 15, and 16 are the same, and the common parts 17, 18, and 19 are stacked and bound by the binding band 20. By doing so, the binding state is stable and the flat cable is prevented from being displaced and deformed. For example, the position of the connector 13 at the terminal portion is always kept at the regular position, and the flat cable can be easily and accurately mounted and assembled. can do.

Further, if the outer shape of the other common part is matched with the maximum shape pattern, a margin is generated in the pattern part, so that the design of the pattern has a margin and the product yield is improved, and the pattern is further standardized. By doing so, the number of man-hours for designing and manufacturing can be reduced, and it becomes possible to easily deal with design changes.

[0013]

As described above, in the flat cable according to the present invention, the outer shape of the common portion of the middle portion of a plurality of flat cables is formed into the same shape, and the flat cables that are laminated are bound by this common portion. , It is possible to stabilize the bundling state and eliminate the deviation and deformation of the product.
