DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable arranging structure of a door opening / closing section in which, for example, an electric component on a door side of an automobile and a power supply section on a body side are connected by a flat cable.

[0002]

2. Description of the Related Art A conventional cable arranging structure of this type is disclosed in, for example, Japanese Patent Application Laid-Open No. 6-278460.
As shown in FIG. 6, the rear part of the flat harness 2 is disposed on the door 1 between the inner panel 3 and the door trim 4, and the front part of the flat harness 2 passes through the room 6 side of the weather strip 5 and the body 7. Is introduced in the pillar 8 of the first embodiment. Then, as shown in FIG. 7, the flat cable 2 has a helical expansion / contraction part 2 extending in the vertical direction in the pillar 8.
The extension portion 2a is extended when the door 1 is opened, and is a margin portion that allows the flat cable 2 to follow the door 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a perspective view of an embodiment in which, for example, a door 21 of an automobile is opened, FIG. 2 is a horizontal sectional view showing the door 21 closed, and the door 21 is attached to a body 23 via a hinge 22. A weather strip 24 for waterproofing between the door 21 and the body 23 is attached to 21. Door 21 is outer panel 2
5, an inner panel 26 and a door trim 27, a window glass (not shown), a drive motor thereof, and the like are provided between the outer panel 25 and the inner panel 26, and a speaker 28, between the door trim 27 and the inner panel 26,
The door trim 27 is provided with a power window switch 29 and the like.

[0007] A flexible flat cable 30 is connected to electrical components such as the drive motor, the speaker 28 and the power window switch 29. The flat cable 30 has a structure in which a plurality of flat conductors are protected on both sides by an insulating sheet, and the insulating sheet is cut out in a strip shape. The rear portion of the flat cable 30 is disposed between the inner panel 26 and the door trim 27, and is fixed to the inner panel 26 by screws 31, for example.

The front portion of the flat cable 30 is led out from a cutout window 27 a formed in the door trim 27, passes through the room 32 of the weather strip 24, and passes through the body 23.
Side, for example, in the front pillar 33. The lower trim 34 is attached to the room 32 side of the pillar 33, and the flat cable 30 is connected to the lower trim 3.
4 is introduced into the pillar 33 through a cutout window 34a.

In the pillar 33, the flat cable 30 is introduced with a curved margin, and a front end thereof is connected with a connector 30a.
0a is connected to the connector 35a of the main harness 35. The flat cable 30 has a braided tube 36
Is mounted between the fixing screw 31 and the connector 30a. A flat cable 30 is provided on the inner surface of the pillar 33.
Cushioning member 37 for preventing generation of abnormal noise due to collision of
Is attached. The notch window 27a of the door trim 27 and the notch window 34a of the lower trim 34
A protector 38 such as a ring protector and a protector 39 for protecting the flat cable 30 are provided.

A guide 40 for guiding the flat cable 30 is provided near the cutout window 34a in the pillar 33.
Are attached to the pillar 33 via the attachment 41. As shown in FIG. 3, the guide 40 has side walls 40a and 40b opposed to each other on both sides of the flat cable 30 with a space between them. A curved surface 40c for changing the direction is formed. Further, as shown in FIG. 4, the main harness 35 is guided vertically from the connector 35a,
It is supported by.

With such a configuration, when the door 21 is opened as shown in FIG.
Following the movement of No. 1, it is pulled out from inside the pillar 33. At this time, the connectors 30a and 35a
The main harness 35 rotates in the direction A while moving toward the guide 40 following 0.

On the other hand, when the door 21 is closed,
Pushes the rear part of the flat cable 30 forward, and the curved surface 40c of the guide 40
Guide to the 3rd side. Thereby, the front portion of the flat cable 30 bends in the pillar 33, and at the same time, the connectors 30a, 35a and the main harness 35 return to the original positions shown in FIG.

As described above, in the embodiment, the guide 40 for changing the moving direction of the flat cable 30 is provided near the notch window 34a in the pillar 33, so that when the door 21 is closed, the extra space of the flat cable 30 is provided. Can be absorbed by curving into the pillar 33. Accordingly, it is not necessary to install the flat cable 30 in the vertical direction, and it is not necessary to form a spiral portion in the flat cable 30.
It is possible to reduce the deviation of the installation space with respect to 0 and the waste of the length of the flat cable 30. Incorporation of these members into the pillar 33 is performed by the lower trim 3.
4 can be removed, so that the mounting workability can be improved.

In the embodiment, since the main harness 35 is rotatably supported in the pillar 33 in the vertical direction, the connector 30 connected to the main harness 35
a and 35 a can be made to follow the moving direction of the flat cable 30, and the stress applied to the flat cable 30 can be reduced. In addition, flat cable 3
Since the braided tube 36 is mounted at 0, the life and appearance of the flat cable 30 can be improved. Also,
Since the buffer member 37 is provided on the inner surface of the pillar 33, generation of abnormal noise due to the abutment of the flat cable 30 can be prevented.

Further, since the flat cable 30 is disposed inside the weather strip 24, a waterproof structure can be made unnecessary, and a through hole of the flat cable which is conventionally required is formed. The work, the work of attaching the grommet to the flat cable, the work of designing the grommet, and the like can be omitted, and the number of parts and the manufacturing cost can be reduced.

Although the flat cable 30 is fixed to the inner panel 26 of the door 21 in the embodiment, it may be fixed to a water proof (not shown). Further, although the front part of the flat cable 30 is curved in the pillar 33, the rear part of the flat cable 30 may be curved in the door 21. Further, although the flat cable 30 is bent, the flat cable 30 may be bent.
It can also be deformed into an arbitrary shape according to the zero habit.

[0017]

As described above, in the cable arranging structure of the door opening / closing section according to the present invention, the moving direction of the flat cable is changed by the guide member, and the surplus portion of the flat cable is accommodated in the extra room. Therefore, the vertical installation space in the extra space can be reduced, and the assembling operation process can be shortened.
