Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Field of Application The present invention relates to a method of attaching a door wire harness to a door in a wire harness used in an electrical circuit of an automobile.

BACKGROUND OF THE INVENTION Automobile doors are mainly composed of an outer door frame and an inner cover plate called a trim cover.
As shown in FIG. 1, a door wire harness W having a converged shape is arranged in a space within a door frame A. The door wire harness W has a connector cl at the end.
Branch line Wl, W, 2, W3 * w4 with y C2y C3, C4, C5...
g W5...... is provided, and the branch line W
1 and w2 are connected to the power window motor and auto door lock solenoid in the door frame A through connectors Cl l and C2, respectively, and branch wires W3 and W2 are connected to the power window motor and auto door lock solenoid in the door frame A, respectively.
4gw5 are pulled out from the work window H and connected to a courtesy lamp, a trunk open switch, a power window switch, etc. provided on the trim cover B through connectors C33C4y' and C5, respectively. The end of the door wire harness W is pulled out through a grommet G and connected to a cowl side harness on the vehicle body side through a connector C.

Then, this door wire harness W is inserted into the door frame A through the working window H, and the grommet G fixed in advance is led out to the outside through the hole in the door frame A. The clamp K is inserted into the hole at the bottom of the door frame and fixed to a predetermined wiring path. Next, connect connectors CI and C2 to the electrical components in door frame A, and then connect connectors C3 and C4.

Connect C5.... to the electrical equipment of trim cover B,
The trim cover B is fixed to the door frame A.

However, with this method, it takes a lot of time to insert the door wire harness W into the door frame A and fasten it to the clamp, which is blind work in a narrow space.
This is an obstacle to speeding up automobile production lines.

Therefore, according to the applicant's prior order, Utility Application No. 58-5397
In the above, by joining a wire harness in advance to a sealing sheet that is attached to a door frame, and attaching the sealing sheet to the door frame, the labor and time of installing the wire harness inside the door frame is reduced. Karuji: Attempts to reduce this have been proposed.

Problems to be Solved by the Invention In the above-mentioned method of attaching a door wire harness to a door via a sealing sheet, the branch wire connector is connected after the sealing sheet is joined to the door frame via the peripheral edge. Connects to the electrical equipment in the door frame, then connects the connector of another branch line to the electrical equipment on the trim cover, and fixes the trim cover to the door frame. Connection of branch lines in automobile manufacturing lines. All work remains to be done, and since the sealing sheet is made of soft synthetic resin, it takes time to attach it using adhesive means, and it is difficult to maintain its shape during storage and transportation, causing branch lines to become tangled. Furthermore, in environments with strong vibrations during use, the wire harness may not be held sufficiently by the sealing sheet.
It requires work such as fixing it to the donor frame in advance.

In contrast, in the present invention, the door wiring harness is provided flat on a cover plate provided inside the door frame, and the door wiring harness is attached to the door frame via the cover plate.

[Structure of the invention]

Means for Solving the Problems In order to achieve the above object, in the present invention, a door wire harness is provided in a flat shape to the inner cover plate of an automobile door, and a part of the branch line is connected to the cover plate. A configuration was adopted in which the cover plate was connected to the electrical equipment provided on the plate in advance, the remaining branch lines were connected to the electrical equipment inside the door frame, and the cover plate was fixed to the door frame.

Embodiment In Fig. 2, A is a door frame of an automobile door, B is a cover plate provided inside the door frame, and the cover plate B has each conductor of the door wire harness W' in parallel and is coated with a bonding agent or a bonding agent. It is fixed in a flat shape with tape, etc.

The door wire harness W', which is arranged flat, has connectors cl'g C2', C3 at the ends.

It is also possible to configure the focusing lead-out section W'' with a connector and have the connector also serve as a waterproof section.

The flat wire harness W' may use strips in addition to ordinary electric wires, and in this case, the branch wires Wl', W2

The cover plate B is provided with a courtesy lamp L, a trunk opening switch 2, and a power window switch 3 as electrical components, and branch lines W3', W4', and W5' are connected through connectors 03', 04', and 05'. Connected in advance.

The cover plate B in this state is combined with the automobile door frame A on the production line, and the connectors are connected.

02' to the branch lines Wl' and W2' to the door frame A.
In addition to connecting the power window motor 4 and the automatic door lock solenoid 5 in the interior, the waterproof part such as the grommet G in the rear lead-out part W'' is connected to the lead-out hole 6 of the door frame A.
Then, cover plate B is fixed to door frame A.

The outlet hole 6 has a structure in which seven parts are cut out on the side of the cover plate B, and it is also possible to push a waterproof part such as a grommet G in the focusing outlet W'' into the outlet hole 6 from the side.

〔Effect of the invention〕

As described above, the present invention provides a wire harness for a door in a flat manner to an inner cover plate of an automobile door, a part of a branch line is connected in advance to an electrical component provided on the cover plate, and the remaining branches are Since the wire is connected to the electrical equipment inside the door frame and the cover plate is fixed to the door frame, the installation work of the door wire harness on the automobile manufacturing line is much simpler than before. The wire harness is laid out flat and does not take up much space, so there is no need to leave any space like in the past.
Unlike the case of finding extra space to route the cable, the cable can be routed in the shortest distance in a straight line, and since it is installed on a cover plate with a fixed shape, it is easy to branch when transporting, storing, or attaching to the door frame. It has the advantage that the wires are less likely to get entangled, and can stably support the wire harness even under conditions of use where there is a lot of vibration.
