Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness wiring structure for an automobile, which is installed inside an instrument panel and supplies electric power to instrument electrical components around the instrument panel.

[0002]

2. Description of the Related Art As a conventional harness wiring structure for an automobile, for example, Japanese Patent Laid-Open No. 58-218451 and Japanese Utility Model Publication No.
As disclosed in Japanese Unexamined Patent Publication No. 0-171768, the harness is fixed along the back surface of the instrument panel with a fastening member such as a clamp and a clip, or is routed to the back of the cowl box at the upper end of the dash panel. The harness along the engine room is fixed by a similar fastening member and routed, the connector at the end of the harness is fixed to the dash side panel, and the harness is penetrated through the dash panel and pulled out into the passenger compartment. The connector at the end or the connector at the end of the harness on the body side for supplying electric power to the rear electrical components of the vehicle body is fitted and connected.

[0003]

In the conventional harness wiring structure, the connector at the harness end wired along the back surface of the instrument panel or the back surface of the cowl box is fixed to the dash side panel as described above. After assembling the instrument panel to the vehicle body, the connectors of the engine room side harness end and the body side harness end are fitted and connected to this connector. It is necessary to work under the instrument panel and work becomes poor.

Further, since the connector connection portion is hidden by the instrument panel and is difficult to see, it is difficult to perform inspection work such as connector connection check.

Therefore, the present invention provides a harness wiring structure for an automobile, which facilitates the harness wiring work and the connector connection work, and the inspection work such as the connector connection check.

[0006]

According to a first aspect of the present invention, there is provided a main harness for supplying electric power to instrument electrical components around an instrument panel along a steering member arranged inside the instrument panel in a vehicle width direction. Along with the wiring, the first connector at the end of the main harness is attached to the bracket fixed to the steering member with the connection port facing upward, and the first connector is attached to the harness end of the engine room side and the body side harness end from above. After the second connector is fitted and connected, the instrument panel is assembled to the vehicle body with the steering member inside.

According to a second aspect of the present invention, the fixed position of the bracket on which the first connector of the main harness according to the first aspect is mounted on the steering member corresponds to the opening for mounting the component of the instrument panel. It is characterized by being set to the position.

[0008]

According to the first aspect of the present invention, before assembling the instrument panel to the vehicle body, the main harness is routed along the steering member existing in the vehicle width direction at the front waist portion in the vehicle compartment. Installation work can be done easily without taking a posture.

Similarly, since the first connector of the main harness is attached to the bracket fixed to the steering member with the connection port facing upward, the harness end of the engine room side and the body side harness end are attached to the first connector from above. The second connector can be easily fitted and connected.

Further, since the inspection such as the connection check of the first connector and the second connector can be visually inspected before the instrument panel is assembled to the vehicle body, the inspection work can be performed easily and accurately.

According to claim 2, the first of the main harness
Since the fixed position of the bracket on which the connector is mounted on the steering member is set to the position corresponding to the opening for mounting the parts of the instrument panel, the first connector is installed after the instrument panel is assembled to the vehicle body. And the second
When checking the connection of the connector or the like, it is possible to easily perform the work through the opening for mounting the component of the instrument panel.

A bracket 7 is fixed to one end of the steering member 3 so as to project toward the front. The bracket 7 has a first connector 8 at the end of the main harness 4.
Is attached with its connection port 8a facing upward.

A plurality of branch lines 4a are branched and drawn out at a required portion of the main harness 4, and a branch line connector 9 for connecting a harness (not shown) to the instrument component side is provided at the end of each branch line 4a. .

Reference numeral 10 penetrates through the dash panel 1 to provide a passenger compartment R
An engine room-side harness 12 that is pulled out inside and fixed to the back surface of a cowl box 11 formed at the upper end portion of the dash panel 1 by a fastening member 6 such as a clamp.
Indicates a body side harness that is routed along the floor side or the like and supplies power to rear body electrical components such as rear speakers, brake lights, and rear lamps (not shown). Each end of these engine room side harness 10 and body side harness 12 is shown. The second connector 13 provided in the section is fitted and connected to the first connector 8 from above before the instrument panel 2 is assembled to the vehicle body.

In this embodiment, the main harness 4 is used.
The fixed position on the steering member 3 of the bracket 7 to which the first connector 8 at the end is attached is defined as an opening for mounting a component of the instrument panel 2, for example, the instrument panel 2 is assembled to the vehicle body, and then the meter 5 is assembled. It is set at a position corresponding to the meter opening 2a to be attached.

The instrument panel 2 is assembled on the vehicle body by fastening both sides of the instrument panel 2 to the dash side panel via brackets (not shown) and fastening the front edge to the rear side of the upper surface of the cowl box 11 with screws or the like.
