【Example】

In FIG. 1, A is a door frame, B is a waterproof sheet, C is a door trim, W is a wire harness, D ₁ is a power window motor, and D ₂ is a door lock actuator.

The door frame A comprises an outer panel A ₁ and an inner panel A _2, and a power window motor D ₁ and a door lock actuator D ₂ are attached to the inner panel A ₂ in the inner space thereof. In the power window motor D ₁ and the door lock actuator D ₂ , a plurality of mounting portions 1 are provided on the mounting surface for the inner panel A ₂ and connectors 2 and 3 are provided in a protruding manner. Packing 4 is provided.

A large number of holes 5 and connector insertion holes 6 are formed at predetermined positions of the inner panel A ₂ , and the power window motor D ₁ and the door lock actuator D ₂ project the respective connectors 2 and 3 from the connector insertion holes 6. In this state, the mounting portion 1 and the fixing hole 5a are aligned with each other and are fixed by bolts or the like. The waterproof sheet B is formed with a connector insertion hole 7 corresponding to the connector insertion hole 6 of the inner panel A ₂ , and the waterproof sheet B is inserted inside the connector insertion hole 7 with the connectors 2 and 3 positioned. Place it on panel A ₂ and temporarily fix it.

A molded mounting portion 9 and a main connector 10 located on a hinge mounting surface 8 of the door frame A facing the vehicle body are provided at an end portion of the flat wire harness W, and an intermediate portion and the other end portion thereof are provided. Mounting boards 11 and 12 having a branch connection structure of wiring are provided. On the mounting surfaces of the mounting boards 11 and 12, connectors 13, 14 and mounting elastic clips 15 and positioning projections 15 'are provided so as to project, and the connectors 13, 14 and mounting elastic clips 15 and positioning projections 15' are provided. A waterproof packing 16 is provided to surround and. On the other side of the mounting board 11, that is, on the door trim side, a rotary connector 17 connected to an operation switch is provided, and on the other side of the mounting board 12, a courtesy lamp 18 is provided.

In the wire harness W, first, the molded mounting portion 9 is fixed in the housing recess 20 by fitting the mounting projection 19 into the engagement hole 21 in the housing recess 20 of the door frame A, and then the mounting board. The positioning projections 15 ′ and the mounting elastic clips 15 of 11, 12 are inserted into the positioning holes 5 b and the clip holes 5 c of the inner panel A ₂ while penetrating the through holes 22 of the waterproof sheet B, and the mounting board 11 is mounted. , 12 are fixed to the inner panel A ₂ , and at this time, the connectors 2 and 3 of the power window motor D ₁ and the door lock actuator D ₂ and the connectors 13 and 14 of the mounting boards 11 and 12 are connected. In this state, the waterproof packings 4 and 16 are pressed against the inner panel A ₂ and the waterproof sheet B around the connector coupling portion to waterproof (FIG. 5).

At this stage, the door trim C with the waterproof packing 30 is put on and waterproofed and fixed. The door trim C is formed with a recess 23 'for accommodating the wire harness W, and the connector 17 and the courtesy lamp 18 are located facing the passenger compartment by fixing the door trim C. That is, in the door trim C, the accommodation recess 23 'is formed in the armrest portion 23, and the connector 17 is located facing the mounting opening 23a formed on the upper surface of the armrest portion 23 (FIG. 2). ..

The connector 17 is rotatably provided by a support shaft 25 in a support frame 24 integrally formed with the mounting board 11 made of synthetic resin, and is provided between the driven part 17 a and the support frame 24. The coil spring 26 biases the connecting end 17b upward toward the mounting opening 23a (FIG. 4). The elastic rubber material may be used instead of the spring.

In FIG. 2, E is a switch unit, which has a switch group 27 on the upper surface, a connector portion 28 on one side, and a mounting leaf spring 29 on the other side that faces the switch portion 27. Therefore, when mounting the switch unit E, the connector portion 28 is inserted downward into the mounting opening 23a so as to be coupled with the connector 17, and then the connector unit 28 is rotated downward to open the other side. It is pushed into the portion 23a and the mounting leaf spring 29 is engaged and fixed to the edge of the opening 23a.

[Effect of the device]

 As described above, the present invention rotatably mounts a connector on a mounting board which is fixed to a door frame and connected to a device inside the door frame, and the connector is positioned at an opening of a door trim to connect a switch unit connector. Since the switch unit is connected to the connector through the opening and the switch unit is fixed in the opening, the mounting of the switch unit in the door trim can be performed easily and quickly in the final stage of the door assembly. In addition, another connector is provided on the mounting board in a protruding manner, and the connector is connected to a connector such as a power window motor through the insertion hole of the door panel. Connection work is also easy.
