An engaging claw portion 10 for the door panel 1 is provided on the bottom of the resistance board 4, and an engaging hole 11 is formed in the door panel 1 to assemble the circuit body 12 on the surface of the panel 1. With the attachment, the lock switch 3 can be locked and connected to the main body 8. The switch 3 and the harness body 2 are joined by a connector 13.

The structure shown in FIG. 2 is characterized in that the motor mechanism portion 15 of the power window is integrally disposed and connected to the intermediate branch harness 14 of the circuit body 12 via the connector 16. The motor mechanism unit 15 includes a motor 17 and the motor 1.
The reduction gear 18 driven by the motor 7 is housed in a resin case 19. The drive shaft 21 of the regulator main body 20 can be engaged with the center of the gear 18.
The drive shaft 21 includes an internal drum 23 that drives a wire 22.
As shown in FIG. 3, the wire 22 has a function of moving the carrier plate 25 of the window up and down along the guide rail 24.

Further, a locking claw portion 26 is provided on the bottom of the case 19, and an engaging hole 27 is provided in the door panel 1, respectively. By assembling the case 19 on the surface of the door panel 1, a drive shaft is provided. 21 and the center of the gear 18 are united. In the figure, 28 is a case cover, and 29 is a nut for fixing the regulator body 20 to the door panel 1.

3 to 5 show an example in which the configuration of the second embodiment of the circuit body for an automobile door according to the present invention, that is, the previous example, is more concretely shown. As shown in FIG. 3, this structure uses an inner side panel frame (steel plate) 32 that is joined to the central portion of the door panel 31, and a flat harness 33 is joined to the surface of the inner side panel frame 32. The motor mechanism portion 15 'of the power window is arranged and connected through the circuit board 34.

As shown in FIG. 4 which is an enlarged exploded view of portion A of FIG. 3, the joint circuit board 34 is a flat harness 3
3 is electrically connected to a joint connector 35 provided on the base plate 3, and one of the connecting brackets 36 of the motor mechanism portion 15 'is fixedly connected to the end of the substrate 34 with a screw 37, and the other side of the bracket 36' and the mechanism portion. The main body 15 'is screwed to the panel frame 32.

A drive shaft 38 is projectingly provided on the motor mechanism portion 15 ', and as shown in FIG. 5, the drive shaft 38 penetrates a hole 39 of the frame 32 and projects to the outside. Then, by assembling the circuit body 41 on the surface of the door panel 31 via the waterproof sheet 40, the drive shaft 38 is attached to the waterproof sheet 40.
It is connected to the regulator drum 43 in the door panel 31 through the seal hole 42 of the.

In the case of a manual window, the circuit body 4
It suffices to remove the motor mechanism portion 15 ′ from 1 and connect a manual lever (not shown) to the regulator drum 43, and it is not necessary to do anything on the door panel 31 side. In FIG. 3, 4
Reference numeral 4 denotes a main connector for body connection, and 45 denotes a joint circuit board which is connected to the joint connector 46 and on which the lock switch 3 and the like can be arranged.

According to the above embodiment, since it is not necessary to route the harnesses 2, 33 inside the door panels 1, 31,
Assembling work can be easily performed, and the harness 3 can be installed linearly in the center of the door panel 31.
It is possible to eliminate the loss by making the installation length of 3 the shortest.
Moreover, it is not necessary to enhance the waterproofness of the connector as in the door panel. In addition, the circuit body 41 is provided on the waterproof sheet 40.
The waterproof connector can be dispensed with by arranging the.

More notable is the door panels 1 and 31.
Since the electrical components (the lock switch 3 and the motor mechanism parts 15 and 15 ') are assembled at the same time when the circuit bodies 12 and 41 are mounted on the surface, troublesome connector connection work to the electrical components (8, 20) is required. It is unnecessary. Further, there is an advantage that the regulator main body 43 in the door panel 31 can be shared in the manual / automatic setting of the window.

6 to 8 show a third embodiment of a circuit body for an automobile door according to the present invention. With this structure, the flat harness 48 can be divided into blocks (three divisions in the embodiment) so that the flat harness 48 can be appropriately assembled and used according to the vehicle specifications, and the relay 49 for the lock detection circuit of the power window and the lock switch 3 can be used. ′ Is arranged in the branch box 52, 53 on the harness main body 48 via the joint circuit boards 50, 51.

The harness main body 48 is composed of three blocks, namely, a first harness 48a for a power window and a door lock mechanism, a second harness 48b for a driver's seat main switch, and a third harness 48c for an electric mirror and audio. Composed.

7, the relay 49 is disposed and connected to the joint circuit board 50, and the board 50 is connected to the harnesses 48a and 48b through the joint connectors 54 and 55. As shown in FIG. The conductor exposed portions 56 and 57 are connected. The board 50 is additionally provided with a main switch connection connector 58 and a power window regulator connection connector (not shown). Then, a front and rear split type box main body 52 made of a synthetic resin is covered from above. The box body 52 has a regulator connector insertion opening 59 and a main switch connector insertion opening 60.
Etc. are provided.

A main switch 61 for opening and closing a window is directly connected to the opening 60 by a connector. Here, since the relay 49 is built in the branch box 52, the power line processing in the main switch 61 is unnecessary (only the signal line is required), and the main switch 52 can be made compact.

On the other hand, as shown in the exploded view of the D portion of FIG. 6 in FIG. 8, the lock switch 3'is formed by the joint circuit board 5
It is rotatably disposed and connected to the terminal portion of No. 1 and is connected to the conductor exposed portion 63 of the harness 48a via the joint connector 62 on the substrate 51. Then, the split-type box body 53 is covered from above.

The branch boxes 52 and 53 are mounted with a circuit body 66 on a central portion of a surface of a door panel 64 (via an auxiliary door panel 65) via a waterproof sheet (not shown), and at the same time as a regulator connector 67 on the door panel 64 side. It is coupled and connected to the lock operating rod 9 '. A mirror connector 68 and a speaker connector 69 are disposed and connected to the harness 48c, and these are also connected to the respective connectors 70 and 71 on the door panel 64 side. In the figure, 72
Indicates a connector on the body side.

According to the present embodiment, the harness 48 can be made into blocks so that productivity can be improved and selection and sharing can be made for each vehicle specification. Further, since the relay is built in the branch box 52, the circuit length between the regulators can be increased. And the main switch 61 can be made thin. Moreover, the branch boxes 52 and 53 can protect the relay 49, the switch 3'and their connecting portions from water, dust and the like.

[0026]

As described above, according to the present invention, the circuit body is mounted not on the inside of the door panel but on the surface thereof.
The conventional blind work is eliminated and the assembly work becomes easier. Furthermore, since the electrical components such as the door lock switch, the power window motor and the relay can be assembled at the same time when the circuit body is mounted, the troublesome connector connection work to the electrical equipment is not required, and the assembling workability is significantly improved. Can be improved.
