DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a door wire harness to a door panel of an automobile or the like.

[0002]

2. Description of the Related Art In general, electric parts such as a switch, a window regulator, and a speaker are mounted on a door of a car and the like, and a door wire harness for supplying power to these electric parts is mounted. Here, the door panel of the door is generally provided with a weather strip for the door for preventing rain and wind from entering the passenger compartment. It is necessary to devise the wiring harness for the door.

As a structure for this purpose, for example, Japanese Utility Model Application
Japanese Patent Publication No. 54849 discloses a structure as shown in FIGS. The door panel 70 shown in FIG. 7 includes an outer panel 71 outside the vehicle and an inner panel 72 inside the vehicle. The inner panel 72 includes an inner side wall 72b that covers the outer panel 71 from the inside of the vehicle (a front side in FIG. 7), a front side wall (hinge side wall) 72a adjacent to a door hinge (not shown), and a peripheral wall (bottom) other than the front side wall. (A wall and a rear wall), and a through hole 78 for inserting a harness and a through hole 82 for attaching various electric components are formed in the inner wall 72b.

A portion of the peripheral wall of the inner panel 72 near the inner wall 72b and the door sash 74 include:
A weather strip mounting portion 76 is formed, and the weather strip 100 can be mounted on the weather strip mounting portion 76 over the entire periphery of the door. Further, a fitting groove 77 is formed in a region extending between the inner side wall 72b and the front side wall 72a so as to cross the weather strip mounting portion 76, and the fitting groove 77 is formed on the inner side wall 7a.
2b. Further, mounting bolt holes 79 are provided above and below the portion formed on the front side wall 72a side in the fitting groove 77.

[0005] In this structure, the door wire harness W is mounted using a mounting tool 90 as shown in FIGS. 8 (a) and 8 (b). The attachment 90 has a front side portion 91 that can be fitted to a portion of the fitting groove 77 located on the side of the front wall 72a, and an inner side that can be fitted to a portion of the fitting groove 77 located on the side of the inner wall 72b. It has an L-shape integrally having a portion 92, and a wire groove 93 is formed on the back side thereof.
The thickness of the front side portion 91 and the inner portion 92 is determined by the fitting groove 7.
7 and the surfaces of both portions 91 and 92 are
a and 72b are set to be flush with the surface.
Further, a through hole 94 penetrating the front part 91 forward and backward is provided.
Are formed, and a projection 95 having a bolt insertion hole 96 is formed above and below the front side.

On the other hand, in the door wire harness W, a plurality of electric wires 81 are arranged in a flat shape, and all the electric wires 81 are gathered in a grommet 84 provided at one end thereof.
The terminal is provided with a connector 86 connected to a power supply (not shown). The grommet 84 is inserted into the through hole 9.
4 (specifically, the periphery of the through hole 94 is fitted into the circumferential groove 84a on the outer peripheral surface of the grommet 84).
At the same time, by attaching a lid 98 to the back surface of the front side portion 91 in a state where all the electric wires 81 are arranged along the electric wire groove 93,
The door wire harness W is fixed to the fixture 90.

According to this structure, the fitting 90 is fitted into the fitting groove 77, and the bolt 99 is inserted into the bolt insertion hole 96 and the mounting bolt hole 79 to fix the fitting 90. By fixing the weather strip 100 thereon by bonding or the like, the door wire harness W can be disposed inside and outside the weather strip 100 while securing the sealing property of the weather strip 100.

At the other end (inside of the room) of the door wire harness, each electric wire 81 is branched appropriately and connected to a plurality of connectors 80, and these connectors 80 are attached to the respective through holes 82. It is designed to be electrically connected to each electrical component.

[0009]

The above structure has the following problems to be solved.

A) As shown in FIG. 10, when the surface of the front side portion 91 of the fixture 90 and the surface of the front side wall 72a are exactly flush with each other, the weather strip 100 is placed thereon.
A good sealing property can be obtained by mounting the rim, but if the thickness of the front side portion 91 has an error, the weather strip 100 may not be able to reliably prevent rain and wind from entering. For example, as shown in FIG. 11A, when the front side portion 91 projects forward from the surface of the front side wall 72a, the weather strip 100 is placed thereon.
When the weather strip 100 is mounted, the weather strip 100 rises to form a gap 41 between the weather strip 100 and the surface of the front side wall 72a. Conversely, when the front side portion 91 is immersed behind the surface of the front side wall 72a as shown in FIG. Therefore, a gap is formed between the front side portion 91 and the weather strip 100, and in any case, there is a possibility that rain and wind may enter the vehicle interior through the gap 41.

B) In the above structure, the fitting 90 is inserted into the fitting groove 7 for the purpose of replacing or repairing the door wire harness W.
7, the weather strip 100 must be removed separately from the weather strip 100 before the work, and after the fitting 90 is re-fitted into the fitting groove 77, the weather strip 100 is further removed. An operation of reattaching the strip 100 is required. That is, when attaching and detaching the attachment 90, the weather strip 100 must be attached and detached without fail. Such a work of attaching and detaching the weather strip 10 is very troublesome, and hinders improvement in workability of maintenance.

In view of such circumstances, the present invention can ensure good sealing performance even if there is a slight error in the shape of a fixture for a door wire harness, and can also be used to replace a door wire harness. It is another object of the present invention to provide a door wire harness mounting structure that does not require a weather strip attaching / detaching operation.

[0013]

According to the present invention, there is provided a door panel having an inner wall facing inward of a vehicle body and a hinge side wall to which a door hinge is connected. A door wire harness for mounting the door wire harness in a region extending between the door panel and the inner wall, and arranging a weather strip over the entire periphery of the door panel. A harness mounting member having a first cover portion covering at least a region corresponding to a wiring region of the door wire harness on the outer peripheral portion of the shape and the inner wall, and a second cover portion covering at least a part of the hinge side wall; The harness mounting member is provided with the second
A harness insertion hole is provided in the cover portion from a surface opposite to the surface facing the hinge side wall to a surface of the first cover portion opposite to the surface facing the inner wall, and the harness insertion hole is provided in the harness insertion hole. Insert the wire harness,
A wire harness for a door was routed on the first cover portion, and the weather strip was provided on the outer periphery of the harness mounting member over the entire circumference while passing through a location inside the vehicle from the harness insertion hole. In this state, the outer peripheral portion of the harness mounting member is fixed to the outer peripheral portion of the door panel.

In this structure, if the weather strip is provided by previously arranging the door wire harness on the harness mounting member, the door wire harness and the weather strip are then simply fixed to the door panel. Mounting can be performed simultaneously and easily. In addition, at the time of maintenance of the door wire harness, the entire harness mounting member may be attached to and detached from the door panel, and troublesome work of attaching and detaching the weather strip is unnecessary. Moreover, since the outer peripheral portion of the harness mounting member, which is the mounting portion of the weather strip, corresponds to the outer peripheral portion of the door panel and has a shape that is continuous over the entire circumference, the sealing performance of the weather strip is kept high.

Further, if the first cover portion is provided with a connector mounting portion for mounting the connector of the door wire harness, the position of the connector is stabilized, and the connector and the mating connector on the electrical component side are connected. Connection work can be performed more smoothly.

As the connector mounting portion, it is preferable that the first cover portion is provided with a through hole penetrating the first cover portion in a thickness direction, and a connector mounting tongue piece is extended from a peripheral portion of the through hole. According to this structure, in a state where the connector is fixed to the connector mounting tongue, the electric wires connected to the connector can be smoothly routed by using the through holes.

Although the specific material of the harness mounting member is not particularly limited, if the harness mounting member and the weather strip are integrally formed of an elastic material, the number of parts is reduced,
Also, the assembly process is simplified.
