Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat electric wire which can be used for wiring vehicles and various electric devices.

[0002]

2. Description of the Related Art Conventionally, for example, in a wire harness for an automobile, it is usual that a large number of covered electric wires are bundled with a vinyl tape or the like and a connector or the like is attached to a required place to produce a circuit network for use. .

[0003]

However, a wire harness is manufactured by arranging a large number of covered electric wires in a pattern shape on a wiring board having substantially the same size as the car body so as to fit the car body. Fold the wire harness and transport it to the car manufacturer.

At the time of assembling to a car body in an automobile manufacturer, an operator has to adjust the shape of the wire harness so that the bent wire harness is expanded and attached to the car body.
Without sufficient knowledge of the structure, it is not possible to three-dimensionally restore a wire harness having a complicated structure. Therefore,
It is extremely difficult to automate the assembly of this wire harness to the vehicle body.

The object of the present invention is to solve the above problems,
It is to provide a flat electric wire which is easy to manufacture and assemble and which can be freely processed according to the shape to be assembled.

[0006]

A flat electric wire according to the present invention for attaining the above object comprises a plurality of covered electric wires arranged in a pattern shape and fixed on a sheet having shape retention. Characterize.

[0007]

In the flat electric wire having the above structure,
A large number of covered electric wires are arranged in a pattern shape and fixed on the sheet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on the illustrated embodiments. FIG. 1 is a plan view of a pattern electric wire for an automobile,
For example, synthetic resin sheet 1 that is relatively thick and has shape retention
The covered electric wires 2 composed of a large number of single wires or stranded wires are arranged in parallel on the upper side in accordance with a predetermined pattern shape to be wired on the vehicle body, and these covered electric wires 2 are bonded at required places as shown in FIG. It is fixed on the sheet 1 by the agent 3. Then, the sheet 1 is punched or cut into an appropriate shape along the covered electric wire 2.

At the connection portion of the covered electric wire 2 to, for example, a connector, the covered electric wire 2 is projected from the sheet 1 as shown in FIG. 3, the covering 4 of the covered electric wire 2 is peeled off, and the core wire 5 is exposed. A metal terminal 6 is welded to the core wire 5 by, for example, ultrasonic welding. The metal terminal 6 has a flat shape, several metal terminals 6 are integrally fixed by the mold resin 7, and the end portion on the side opposite to the core wire 5 has a flat blade shape so as to be easily inserted into, for example, a connector. .

In the embodiment, the covered electric wire 2 is directly fixed onto the sheet 1 by the adhesive 3, but the covered electric wires 2 are fixed to each other by using the synthetic resin member, and then the synthetic resin member is fixed. It may be adhered onto the sheet 1.
Alternatively, it can be fixed on the sheet 1 by means other than an adhesive, for example, a hot melt adhesive, an adhesive tape, ultrasonic bonding, metal fittings, or the like.

Further, although the embodiment has been described with respect to the case where the molded metal terminal 6 is connected to the core wire 5, the molded metal terminal 6 is not necessarily connected.
For example, the metal terminals 6 may be individually connected directly to the core wire 5. Although the metal terminal 6 has been described as a male terminal, it may be a female terminal.

Further, the covered electric wires 2 are not always arranged in parallel, but may be arranged in an appropriate pattern. Further, for the efficiency of wiring, the sheet 1 to which the covered electric wire 2 is adhered may have a crease, and the sheet 1 may be partially folded and used.

Further, by partially intersecting the covered electric wire 2 on the sheet 1, it is possible to make the wiring multi-layered. Further, the covered electric wires 2 can be arranged on both sides of the sheet 1, and in that case, a hole can be provided in the sheet 1 and the covered electric wire 2 can be dipped in this hole.

In such a flat electric wire, a large number of covered electric wires are arranged in a pattern shape and fixed on a sheet having a shape-retaining property. Therefore, when the electric wire is attached to the vehicle body, the flat electric wire is simply applied to a necessary portion of the vehicle body. It can be installed as it is, requires little skill and time, and has the possibility of automation. The present invention can be applied to various electric devices that require wiring other than automobiles.

[0015]

As described above, in the flat electric wire according to the present invention, a large number of covered electric wires are arranged in a pattern shape and fixed on a sheet having shape retention property. It is extremely easy to attach.
