Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door harness assembly structure for arranging a wire harness on a door trim side of an automobile and connecting a centralized connector of the wire harness and a standby connector on a door panel side. .

[0002]

2. Description of the Related Art FIGS. 18 to 20 show a conventional door harness assembling structure. In FIG. 18, reference numeral 81 denotes a door panel of an automobile, 82 denotes a waterproof sealing screen attached to the door panel 81, and 83 denotes a door panel 8
1 shows a door trim to be mounted on the vehicle.

[0003] A wire harness (door harness) 84 is routed inside the door panel 81. The wire harness 84 is led out from an opening 85 of the door panel 81, and a male connector 86 is provided at the end of each branch line 84a.
As shown in FIG. 19, the distal end side of the wire harness 84 is led out of the front panel through the insertion hole at the front end of the door panel 81 together with the elastic grommet 87 for waterproofing, and is connected to the wire harness (not shown) on the vehicle body side. In the figure, reference numeral 88 denotes a speaker mounting hole, and 89 denotes a connector for connecting a speaker.

Further, in FIG. 18, a door panel 81 is provided with an auxiliary device such as a speaker 90, a power window motor and a door lock unit (not shown). Also,
The sealing screen 82 is formed with a slit hole 91 for inserting a wire harness. The sealing screen 82 is attached to the door panel 81, and the wire harness 84 is led out of the slit hole 91 to the door trim 83 side.

[0005] The door trim 83 is provided with a switch unit 93 for power window on an armrest 92.
A speaker cover 94 is provided below the armrest 92. As shown in FIG. 20, when assembling the door trim 83, the male connector 86 of the wire harness 84 is connected to the female connector of the switch unit 93.

However, in the above-described conventional structure, as shown in FIG. 19, the leading end side of the wire harness 84 is led out from the inside of the door panel 81 by using the panel hole 8.
The work had to be performed by groping (blind work) by putting in a hand from 5, 88, and the workability was extremely poor. Further, as shown in FIG. 20, in order to connect the male connector 86 of the wire harness 84 to the female connector of the switch unit 93, both connectors must be joined in the armrest 92 of the door trim 83 in a groping state. Similarly, workability is poor,
There is also a concern that the fitting between the two connectors is likely to be incomplete. Since there are many groping operations as described above, there is a serious problem that the working efficiency is reduced in the vehicle assembly line.

Various proposals have been made to solve this problem, and FIG. 21 shows a conventional door harness assembling structure described in Japanese Utility Model Laid-Open No. 5-19014. In this structure, a flat wire harness (flat harness) 96 is surface-mounted on the door panel 95, and
The flat harness 98 is mounted on the back of the door trim 97,
At the same time that the door trim 97 is assembled to the door panel 95, the connectors 99,
100 are mutually connected.

The flat harness 96 on the door panel 95 side
Is bent at a right angle at the front end 101 of the door panel 95, and has a waterproof elastic grommet 10 on its outer periphery.
2 is attached, and a connector 103 for the vehicle body is provided at the front end of the harness. The grommet 102 is a door panel 81 (FIG. 19) as in the previous example.
It is not necessary to derive from the holes.

The connectors 99 and 100 of the flat harnesses 96 and 98 have a plurality of terminals (not shown) inside. The flat harness 96 on the door panel side is connected to auxiliary equipment such as a power window motor, and the flat harness 98 on the door trim side is connected to a switch unit (not shown) by, for example, contact between flat terminals. By connecting the two connectors 99 and 100, the switch unit and each auxiliary device are electrically connected.

However, in the above-described conventional structure, since the connectors 99 and 100 for connecting the door panel side and the door trim side are integrated with the flat harnesses 96 and 98, for example, a plurality of door harnesses on the door panel 95 side are provided. If one of the auxiliary machines fails, only the desired terminal of the flat harness 96 connector cannot be replaced, and the entire flat harness 96 must be replaced, which is costly and requires less maintenance. There was a problem that the work was also troublesome.

[0011]
