Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flexible flat harness including a flexible printed circuit (hereinafter abbreviated as FPC) and a flexible wiring circuit (hereinafter abbreviated as FWC) used for vehicles and the like.

[0002]

[Prior art]

 Recently, a copper foil is punched out to form a circuit and the conductive member is coated on both sides with a resin film such as polyethylene terephthalate or polyimide, or a conductive member consisting of a large number of thin conductive wires is coated on both sides with the resin film. Flat harnesses such as FWCs are provided, and these flat harnesses are advantageous in that they do not take up space and are easy to install.

[0003]

[Problems to be solved by the device]

 In the flat harness, as shown in FIG. 5, usually, a plurality of required conductive circuits A to D arranged at the same location are provided in the inner portion of one harness 1. Since the circuit is provided, the flat harness has a large area, that is, the width is wide. Depending on the installation location, the flat harness may be too wide to be installed.

Further, when the above circuit is formed by punching out a copper foil, if a flat harness is manufactured for each grade of a vehicle model, the number of product numbers increases, and the product number of the flat harness becomes complicated, which makes management difficult. . Therefore, we usually do not manufacture flat harnesses by grade, but roughly classify them so that several grades are included. Among them, the high-grade car model has a flat harness with all circuits punched from a single copper foil. Therefore, the area of the flat harness is inevitably large, and there arises a problem that the flat harness cannot be installed in the narrow place.

Further, since the circuit required for the vehicle type is provided as described above, depending on the vehicle type, unnecessary circuits are not energized, but in that case, expensive copper foil is used. There is also the problem that is wasted.

The present invention has been made in view of the above problems, and it is possible to reduce the area of a flat harness, that is, the width of the flat harness so that it can be installed even in a narrow space, and waste copper foil. The purpose is to prevent the occurrence of wiring mistakes by making it easier to identify the electrical system to which the circuit provided in the flat harness is connected.

[0007]

[Means for Solving the Problems]

 That is, according to the present invention, a flat harness composed of a flexible printed circuit or a flexible wiring circuit in which a conductive member is sandwiched between insulating films is formed separately for each electric equipment system, and these divided parts are formed. The present invention provides a flat harness characterized in that the insulating film of the flat harness formed as described above is provided with different hues depending on the electrical system.

[0008] Further, the flat harnesses in which the colors of the insulating film are different and are divided for each electrical system are stacked and arranged.

The insulating film may have different hues on both sides, or may have different hues on only one side. The insulating film may be colored or formed by mixing the insulating film itself with a paint, or may be attached with a tape or the like having a different hue on the entire surface of the transparent insulating film or at a required position. .

[0010]

[Action]

 As described above, when the conductive member is formed by dividing each electric component system and the conductive member is covered with the insulating film, the area, that is, the width of the flat harness can be reduced. Moreover, the waste of copper foil can be eliminated by using only a flat harness equipped with a necessary conductive circuit according to the vehicle type.

[0011] Furthermore, if flat harnesses formed by being divided according to the electrical system are stacked and arranged, the wiring space can be reduced. Moreover, since the hue of the insulating film of the flat harness is changed for each electrical system when arranging the layers, it is possible to easily prevent wiring mistakes.

[0012]

【Example】

 Hereinafter, the present invention will be described with reference to the embodiments shown in the drawings. The flat harnesses 10A, 10B, 10C, and 10D shown in FIG. 1 are obtained by dividing a plurality of conductive circuits A to D having different electrical system provided in the flat harness 1 shown in FIG. It is provided with one conductive circuit. That is, the flat harness 10A has a conductive circuit A, the flat harness 10B has a conductive circuit B, the flat harness 10C has a conductive circuit C, and the flat harness 10D has a conductive circuit D. Therefore, the width W1 of the flat harnesses 10A to 10D is about half the width W2 of the conventional flat harness 1.

As shown in FIG. 2, in each of the flat harnesses 10 A to 10 B, a conductive member 11 formed by punching out a copper foil is covered with insulating films 12 and 13 on both sides, and the hues of the insulating films 12 and 13 are different from each other. Is changed for each flat harness 10A to 10D. That is, the colors of the insulating films 12 and 13 are red in the flat harness 10A, blue in the flat harness 10B, yellow in the flat harness 10C, and green in the flat harness 10D.

The colors of the insulating films 12 and 13 are obtained by mixing paint on the insulating films themselves, and are preferably transparent red, blue, yellow and green, respectively. Incidentally, tapes having different hues may be attached to identifiable portions such as side edges of the insulating film.

When the flat harnesses 10A to 10D are to be installed on a vehicle door, the conductive circuit A is a door lock system, the conductive circuit B is a door mirror system, and the conductive circuit C is a power system. The window system and the conductive circuit D are respectively connected to the electrical system that composes the step lamp system.

As described above, the flat harnesses 10A to 10D, which are formed by being divided according to the electrical equipment system, are stacked and arranged as shown in FIG. These flat harness harnesses 10A to 10D are arranged by inserting one end on the power source side into one connector 20 and connecting different connectors (not shown) to the other end on the electrical component side. ing.

As shown in FIG. 4, when it is necessary to fold and arrange the flat harnesses, the flat harnesses 10X and 10Y that need to be folded are positioned at both ends of the laminated flat harnesses. And it can be stacked without problems.

At the time of the above-mentioned stacking arrangement, the flat harnesses 10A to 10D can be easily identified by the hue of each electrical equipment system, and the occurrence of wiring mistakes can be reliably prevented.

[0019]

[Effect of device]

 As is clear from the above description, since the flat harness according to the present invention is formed by being divided according to the electrical system, the area of the flat harness, that is, the area of the flat harness, The width can be reduced. Further, when the divided flat harnesses are stacked and arranged, they can be arranged in the same place as in the case of forming one flat harness. Therefore, there is an advantage that it can be installed in a place where the installation space is narrow and that the installation space is not required.

Further, since the hue of the insulating film of the flat harness divided according to the electrical equipment system is different, it is possible to prevent the occurrence of wiring mistakes.

Furthermore, since flat harnesses having necessary circuits are laminated and used, there are advantages that unnecessary circuits can be eliminated and waste of copper foil can be eliminated.
