Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure of a vehicle such as a wire harness connected to an electrical component and a relay wire harness connecting the wire harnesses.

[0002]

2. Description of the Related Art Conventionally, a wire harness of an electric component of a vehicle is inserted through a hollow portion formed in a body panel of the vehicle or interposed between a body panel and a trim mounted on the body panel. For example, in the case where electric components such as a rear glass defogger, a high-mount stop lamp, and an electric open / close curtain are mounted on a back door of a vehicle, a wire harness of these electric components is attached to the back door. Is inserted through a hollow part formed in the door panel, and only each connection terminal or connector is led out from an opening formed in the door panel and connected to the connection terminal or the like of each electrical component.

[0003] Recently, in view of the fact that the above-mentioned wiring structure which requires insertion work into a hollow portion makes the work of assembling the wire harness extremely inefficient, the wiring harness is used for interior materials such as door trims. And a wiring structure in which a wire harness is integrally mounted with the door trim by assembling the wiring harness with a door panel.

[0004]

However, in the wiring structure integrated with the interior material as described above, simply integrating the wire harness into the interior material can reduce the thickness of the interior material.
In some cases, the integration may be limited by the area or shape due to space limitations.For example, when the wiring harness is complicated due to a large number of branches and connectors, the wiring harness is bulky and relatively It becomes difficult to integrate a wire harness with a thin interior material. In addition, in such a complicated wire harness, an assembling work to an interior material is complicated, and the demand for automation is not met.

Further, in recent years, different types of vehicles, such as grades and presence / absence of optional equipment, have been differentiated. Therefore, it is necessary to form an interior material by integrating a dedicated wire harness for each grade. There is also a concern that the types of interior materials will increase, and it will not be possible to meet the demand for the common use of components.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a vehicle wiring structure that can efficiently integrate a wire harness into an interior material.

[0007]

A wiring structure for a vehicle according to the present invention is a wiring structure for a vehicle in which a wiring harness constituting wiring of electrical components is integrally provided in an interior material, wherein the wiring harness has a built-in wiring circuit. And a wiring member for connecting the connection member and the power distribution member, respectively, and the wiring member is formed of one or more unbranched single wires. These single wires are provided integrally with the interior material (claim 1).

According to such a wiring structure, a complicated branch structure necessary for wiring is incorporated in the wiring circuit of the power distribution member, so that even a complicated wiring structure having many branches can be connected to the power distribution member. Since the simple structure of connecting the members with a single-wire wiring member can be maintained, the thickness of the interior material is not easily restricted when the wire harness is integrated into the interior material, and the assembly to the interior material is easy. Becomes

In the above wiring structure, the wiring harness constitutes a wiring selected from a plurality of types of wiring according to the specifications of the vehicle, and the wiring member and the connecting member can correspond to wiring of various specifications. The power distribution member has a built-in wiring circuit for configuring the selected wiring and is detachable with respect to the wiring member. When the power distribution member is mounted on the wiring member in a fixed positional relationship, the power distribution member is selected as described above. (Claim 2).

According to such a wiring structure, parts other than the power distribution member can be shared, so that wiring having different specifications can be configured only by selectively mounting the power distribution member corresponding to the specification. Becomes possible. For this reason, it is possible to suppress an increase in the types of interior materials, and to suitably meet the demand for common use of components.

On the other hand, the door trim 50 is fixed to the door panel 12 of the back door 10 by a resin clip or the like.

The door trim 50 includes a door lock device 22.
The wire harness 52 for the electrical components such as is provided integrally. The wire harness 52 includes a connector 54
And a connector 58 connected to the joint box 56 via a wiring member 57 made of an electric wire.

The connectors 54 and the connectors (connection members) 58 are connected to the connectors 18, 24, 30 on the right side of the door panel 12 and the connectors 38, 4 on the left side, respectively.
4, and each has a single connector structure, but is configured to be integrally fitted with the connectors 18, 24, 30 and the connectors 38, 44, respectively.

The joint box 56 includes an ECU
And the like. When the connectors 54 and 58 are connected to the connectors 18 and the like of the door panel 12, the wiring circuit connects the electric components such as the door lock device 22 mounted on the back door 10 to the main harness 14 and the roof side wire. The circuit is configured to be electrically connected to a controller or the like on the vehicle main body side via a harness.

In the wiring harness 52, all the branching structures necessary for wiring are formed in the joint box 56.
The wiring member 57 for connecting the connector 58 and the joint box 56 has a simple configuration composed of a plurality of single wires without branching as shown in FIG.

The wire harness 52 is, for example, integrated with the door trim 50, and is fixed to the door trim 50 with only the connectors 54 and 58 exposed on the side to be attached to the door panel 12, or the surface of the trim. Mounted on The connectors 54 and 58 are fixed toward the rear of the vehicle so as to correspond to the connectors 18, 24 and 30 on the right side of the door panel 12 and the connectors 38 and 44 on the left side of the door panel 12. 12, the connector 54 of the door trim 50 and the connectors 18, 24, 30 on the right side of the door panel 12 are fitted together, and the connector 58 of the door trim 50 and each of the connectors on the left side of the door panel 12 are correspondingly fitted. The connectors 38 and 44 are fitted. Further, as for the wiring member 57, the single wires are arranged in parallel with each other and linearly along the surface of the door trim 50, and are fixed between the pad members.

According to the back door 10 configured as described above, when the door trim 50 is attached to the door panel 12, the connector 18 and the like of each electrical component attached to the door panel 12 and the connector of the wire harness 52 are attached. 54, 58 are fitted to each other, thereby
Each electrical component such as the door lock device 22 mounted on the vehicle harness 0 is electrically connected to a controller or the like on the vehicle body via the joint box 56 of the wire harness 52 and the main harness 14. That is, by attaching the door trim 50 to the door panel 12, the wiring of all the electrical components mounted on the back door 10 is completed.
Therefore, for example, the wire harness can be easily assembled in comparison with a conventional structure of this type of back door in which a wire harness is inserted into a hollow portion of a body panel of a vehicle and then connectors are fitted together. Therefore, the assembling time of the back door 10 can be greatly reduced.

Moreover, in the back door 10, a necessary branch structure for wiring of the wire harness 52 is incorporated in a wiring circuit of the joint box 56, whereby the wire harness 52 is connected to the joint box 56 and the connector 5.
8 is linearly connected by a wiring member 57 made of a single wire, so that the wiring harness 52 is complicated while configuring the wiring of a plurality of electrical components such as the door lock device 22 as described above. It is not bulky. Therefore, the wire harness 52
When the wire harness 52 is provided on the door trim 50, the wire harness 52 is not easily restricted by the thickness, area, shape or the like of the door trim 50.
Can be integrated. In addition, because of the simple configuration as described above, the work of attaching the wire harness 52 to the door trim 50 can be easily performed, and therefore, it is possible to sufficiently respond to a request for automation.

The back door 10 described above is
This is a typical example of a door structure to which the wiring structure of the vehicle according to the present invention is applied, and the specific structure can be appropriately changed without departing from the gist of the present invention.

For example, in the back door 10, the connectors 24 and the like of the electrical components such as the door lock device 22 and the like are concentrated and arranged at two places on the left and right sides of the door panel 12, and two corresponding connectors 54 and 58 are connected to the wire harness 52. Although the connector is provided to fit each connector, that is, the connector fitting is performed at two places, the number of fitting places of the connector is not necessarily limited to two places, for example, one place or There may be three or more places.
However, when connector fitting is performed at one place, the door panel 1
If each electrical component and the connector mounting position in 2 are separated from each other, there is a problem that the wire connecting the electrical component and the connector becomes long and the wiring becomes complicated. In the case where the door trim 50 is attached to the door panel 12, there is a problem that it is difficult to align the connectors when the door trim 50 is attached to the door panel 12. Therefore, it is most convenient to perform the connector fitting at two places as in the case of the back door 10 from the viewpoint of the wiring of the electrical component and the connector and the assemblability of the door trim 50.

Also, depending on the specifications of the vehicle, etc., the back door 1
In the case where each of the above-mentioned electrical components mounted on the wiring harness 52 can be selectively attached, the connector 58 and the wiring member 57 in the wire harness 52 are configured to correspond to the wiring of all the electrical components, and the joint box A wiring circuit in which the wiring member 57 is configured to be detachable from the wiring member 57 and a joint box 56 corresponding to each specification is provided, that is, a wiring harness 52 corresponding to each specification is configured by being attached to the wiring member 57. Are provided for each specification, and these joint boxes 56 are selectively connected to the wiring member 5 according to the specification.
7 may be attached. According to such a configuration, in the door trim 50, the joint box 56
Since all other parts can be shared, parts can be suitably shared even when the number of specifications is large. In the case of this configuration, the wiring member 5
If the joint box 56 is assembled in advance from the outside of the door trim 50 in the assembling process, the time required to manage the door trim 50 for each specification during component management can be increased. In addition, there is an advantage that the maintenance can be improved when the joint box 56 is damaged or the like. In the case of this configuration, for example, when each single line of the wiring member 57 is formed of a band-shaped metal plate or the like, and the joint box 56 is mounted on the door trim 50, the terminals provided on the joint box 56 are connected to a predetermined metal plate. Can be adopted.

Further, in the wire harness 52,
The connector 54 is provided integrally with the joint box 56,
The connector 54 is integrally connected to the connectors 18 on the right side of the door panel 12. For example, as shown in FIG. 3, the connectors correspond to the connectors 18 on the right side of the door panel 12, respectively. 62, 64,
66 may be connected to the joint box 56 via electric wires. The connector 58 of the wire harness 52 is also connected to the door trim 50 as described above.
It is not always necessary to provide the wiring member 57 to the outside from the door trim 50 to some extent, so that the connector 58 may hang down from the door trim 50.

As the wiring member 57, a bus bar, an FPC, a bare conductor, or the like can be employed in addition to the electric wire.
