Abstract

PROBLEM TO BE SOLVED: To make a laminate film the same width as circuit conductors so as to avoid loss, and require no cutting facility by sticking in independently formed fitting piece to the laminate film insulation protecting flat circuit conductors. SOLUTION: In an electric wiring in which a plurality of copper rows are arranged in parallel so as to comprise flat circuit conductors 3 and the same is insulation protected by a laminate film 1, a fitting piece 2 independently formed of the laminate film 1 is stuck thereto. The fitting piece 2 equipped with a hole for fixture fitting 2A is made of a plastic film similar to the laminate film 1, is formed into predetermined width and length, preferably in thicker, and is stuck to the laminate film 1 in a lengthwise direction. The fitting piece 2 is arranged between the conductors 3 and the laminate film 1, or on the outer face of the laminate film 1, or a U-shaped fitting piece is arranged between the conductors 3 and the laminate film 1, or on the outer face of the laminate film 1, and is stuck thereto. The fitting piece 2 may be formed of a resin-made plate or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat electric wiring used for an internal wiring of an automobile or the like.

[0002]

2. Description of the Related Art In recent years, flat electric wiring is used as an internal wiring of an automobile, in which a flat circuit conductor formed by arranging a plurality of copper strips, bare wires, covered wires and the like in parallel is insulated and protected by a laminate film. ing. The flat electric wiring is fixed to a vehicle body or the like after being wired inside an automobile or the like.

[0003] Conventionally, in order to fix a flat electric wiring to a vehicle body or the like, as shown in FIG. In FIG. 3, reference numeral 3 denotes a flat circuit conductor formed by arranging a plurality of copper strips in parallel.

In order to manufacture the flat electric wiring as described above, first, as shown in FIG. 4, the circuit conductor 3 is covered with the laminate film 1 and then the unnecessary part A of the laminate film 1 is cut out to attach the mounting piece 2. Had formed.

[0005]

However, according to the method of cutting out the unnecessary portion A of the laminated film 1 and forming the mounting piece 2 as described above, the wide laminated film 1 must be used. However, there was a problem that it was large and uneconomical. Further, there is a problem that expensive cutting equipment is required to form the mounting pieces 2.

[0006]

SUMMARY OF THE INVENTION The present invention provides a flat electric wiring which solves the above-mentioned problems. The flat electric wiring comprises a flat circuit conductor insulated and protected by a laminate film. The flat electric wiring is characterized in that it is formed separately from the laminate film and includes a mounting piece fixed to the laminate film.

The mounting piece is formed separately from the laminate film, and the mounting piece formed separately from the laminate film is fixed to the laminate film, so that the width of the laminate film is substantially the same as the width of the circuit conductor. Can be used. Therefore, the cost of the laminated film is reduced. Also, no cutting equipment is required, and equipment costs are reduced. Further, it is not necessary to separately prepare a fixing tool for fixing the flat electric wiring to the vehicle body or the like.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of the flat electric wiring according to the present invention. This flat electric wiring is a flat circuit conductor 3 composed of a plurality of copper strips arranged in parallel.
Is insulated and protected by the laminate film 1 in the same manner as the conventional flat electric wiring. However, in the present invention, the mounting piece 2 is formed separately from the laminate film 1 and separate from the laminate film 1. It is characterized in that the mounting piece 2 formed of a body is fixed to the laminate fill 1.

That is, the mounting piece 2 is formed in advance with a predetermined width and a predetermined length from a plastic film similar to a laminate fill. The thickness is preferably larger than the thickness of the plastic film from the viewpoint of strength.
The mounting piece 2 is provided with a hole 2A for mounting a fixture. The mounting piece 2 is fixed to a predetermined position in the longitudinal direction of the laminate fill 1 in advance. The number of the mounting pieces 2, the mounting intervals, and the laminating film 1
The length of the protruding portion and the like are appropriately determined in consideration of the attachment position to the vehicle body and the like.

In order to fix the mounting piece 2 at a predetermined position in the longitudinal direction of the laminate fill 1, the mounting piece 2 is arranged between the laminate fill 1 and the circuit conductor 3 as shown in FIG. As shown in FIG.
A configuration in which the mounting piece 2 is arranged and fixed on the outer surface of the laminate fill 1, as shown in FIG. 2C, the U-shaped mounting piece 2 is arranged so as to wrap the circuit conductor 3, and the laminate fill 1 is provided on the outer periphery thereof. 2 (d), a U-shaped mounting piece 2 is attached to the outer surface of the laminate fill 1.
Any configuration can be adopted, such as a configuration in which is disposed and fixed.

The mounting piece 2 used in the present invention may be formed of a resin plate or the like. The material and number of the circuit conductors 3 are appropriately selected, and the material and the like of the laminate fill 1 are also appropriately selected. Further, the flat circuit conductor used in the present invention may be bent, or may be a copper strip, a bare wire, a covered wire, or a copper conductor formed by etching.

[0012]

As described above, in the flat electric wiring according to the present invention, the attachment piece is formed separately from the laminate film, and the attachment piece formed separately from the laminate film is fixed to the laminate film. Therefore, a film having a width approximately equal to the width of the circuit conductor can be used as the laminate film. Therefore, the cost of the laminated film is reduced. Also, no cutting equipment is required, and equipment costs are reduced. Further, since the mounting piece is fixed to the laminate film, it is not necessary to separately prepare a fixing tool for fixing the flat electric wiring to the vehicle body or the like.
