BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door harness for an automobile, and more particularly, to a structure in which a harness made of a flexible flat conductor cable also serves as a sealing sheet, thereby reducing the weight of the harness and mounting the harness. This is for facilitation and the like.

[0002]

2. Description of the Related Art Generally, an automobile door comprises an outer door frame 1 and an inner trim cover 2 as shown in FIG.
Conventionally, the above door frame 1
The wire harness 3 was arranged in the space inside.

[0003] The wire harness 3 includes branch lines 5a, 5b, 5 provided with connectors 4a, 4b, 4c, 4d, 4e, respectively.
c, 5d and 5e, of which the branch lines 5a and 5b are connected to a power window motor and an automatic door lock solenoid (not shown) in the door frame 1 via connectors 4a and 4b, respectively. .

Further, branch lines 5c and 5d are drawn out from working holes 1a of the door frame 1,
They are connected via c and 4d to a trunk open switch and a power window switch provided on the trim cover 2 (not shown).

Further, an end of the wire harness 3 is pulled out to the outside via a grommet 6 and is connected to a cowl side harness (not shown) on the vehicle body side by a main connector 4.

At the time of mounting work of the automobile harness having the above configuration, first, the wire harness 3 is inserted into the space in the door frame 1 from the work hole 1a, and the grommet 6 previously fixed to the wire harness 3 is inserted. The main connector 4 is led out to the outside through the hole of the door frame 1, and the clamp 7 previously fixed to the wire harness 3 is also locked in the hole at the bottom of the door frame 1 and fixed to a predetermined routing path. . After that, the connectors 4a and 4b are connected to the power window motor and the automatic door lock solenoid in the door frame 1, and the connectors 4c and 4d are connected to the trunk open switch and the power window switch of the trim cover 2 and the like. To the door frame 1.

However, in the above-mentioned harness for automobiles,
Connect the wire harness 3 to the door frame 1 through the work hole 1a.
A large amount of time is required for the work of inserting the clamp 7 in the narrow space and the work of locking the clamp 7 by groping in this space, which is an obstacle to speeding up the production line of the automobile.

No. 720)

[0009]

However, in the configuration according to the above proposal, since the sealing sheet is formed of a soft synthetic resin sheet (for example, polyvinyl chloride), the wiring harness is heavy and the sealing sheet is made of a heavy material. Since it is difficult to maintain the shape of the seat, the work of attaching the seat to the door frame is not easy, and the branch wires of the wire harness may be entangled during storage or transportation. Further, in the above-described configuration, since the heavy wire harness is held only by the soft sealing sheet, the wire harness is not sufficiently held against the vibration during the running of the automobile, and the wire harness is not attached to the door frame. It is necessary to separately provide means such as fixing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the conventional automobile harness, and is intended for an automobile which can be easily attached to a door frame and has a sufficient harness. It is intended to provide a door harness.

[0011]

According to the present invention, in order to solve the above-mentioned problems, the present invention comprises a flexible flat conductor cable, and the flexible insulating film covers the inside of the door frame. We provide door harnesses for automobiles that are used as sealing sheets.

Specifically, in the harness, the first flexible insulating film of the flexible flat conductor cable has substantially the same outer shape as the inside of the door frame vehicle, and the surface of the first flexible insulating film is A second conductor having a predetermined outer shape on the surface of the conductor is adhered to the conductor so as to form a predetermined wiring route.
The first flexible insulating film is adhered and fixed to the door frame by an adhesive injected into a peripheral concave portion inside the door frame,
The structure also serves as a sealing sheet that closes the space inside the door frame.

A conductor is bonded to the first flexible insulating film having flexibility, and a metal foil having the same shape as the first flexible insulating film is bonded to the first flexible insulating film. It is preferable to use the conductive insulating film and the metal foil as a sealing sheet for covering the inside of the door of the vehicle (claim 2).

More specifically, a metal foil is bonded between first and second flexible insulating films having substantially the same outer shape as the inside of the door frame, and the first and second flexible insulating films are bonded. While the film and the metal foil also serve as a sealing sheet, a conductor is adhered to the surface of the first flexible insulating film so as to form a predetermined wiring path, and a second wiring is formed on the surface of the conductor. Are bonded to each other.

[0015]

With the automobile door harness having the above-mentioned structure, it is not necessary to prepare a wire harness and a sealing sheet separately from each other and bond them when manufacturing the harness. A harness for an automobile door can be obtained only by making the shape of the flexible insulating film into the shape of the sealing sheet when manufacturing the flexible flat conductor cable.

Further, since the harness and the sealing sheet are formed only by the flexible flat conductor cable, the weight of the wiring harness, which is a conventional heavy object, is reduced and the shape of the sealing sheet is maintained as compared with the structure in which the wiring sheet is adhered to the sealing sheet. It is possible to prevent the branch lines from being entangled in an accordion curtain shape or a roll shape during storage and transportation.

Further, since the harness and the sealing sheet are constituted only by the flexible flat conductor cable, the weight is reduced as compared with the conventional structure in which a heavy wire harness is adhered to the sealing sheet, and the vibration during driving of the automobile is reduced. The harness can be securely held only by the sealing sheet.

Further, in a state in which a part of the flexible insulating film (sealing sheet) of the flexible flat conductor cable is attached to the door frame, the connector of the branch line and each device can be connected. Since the remainder of the sealing sheet can be attached to the door frame, the work of attaching to the door frame becomes easy.

In the case where the metal foil is provided as described above, in addition to the above-described operation, the periphery of the flexible flat conductor cable can be formed only by attaching a sealing sheet to a door frame at a ground potential with screws or the like. , EM associated with computerization (multiplex transmission)
Can be set to ground potential for I (electromagnetic shielding effect) measures. In addition, if a magnetic metal foil is used, the operation of attaching the harness using a magnet can be easily automated.
