Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for electrically connecting wire harnesses arranged in an automobile.

[0002]

2. Description of the Related Art Conventionally, in order to connect a wire harness arranged on the engine room side of an automobile to a wire harness arranged on various devices and switches installed in the vehicle compartment, the wire harness is arranged on the engine room side. The installed wire harness was pulled into the passenger compartment and the connector was connected at a location where connection work was easy.

[0003]

However, when the wire harness disposed on the engine room side is pulled into the vehicle compartment as described above, not only the path length of the wire harness becomes longer and the weight increases, but also the wire harness. There is a problem in that it is wasteful and uneconomical, and that the wiring system is complicated and connection work and maintenance and inspection work are extremely difficult.

The present invention has been made in view of the above problems, and an object thereof is to provide a method for connecting a wire harness which is excellent in workability and economy.

[0005]

According to the present invention, a bolt insertion hole 3 and a connector 1 in which a nut 4 is embedded at the open end of the bolt insertion hole 3 are attached to a terminal portion of one wire harness W to be connected,
The tip portion of the connector 1 is fitted and locked to the edge of the fitting opening a formed in the vehicle panel A, and then the nut provided on the connector 1 at the end portion of the other wire harness W ′ to be connected. A bolt 11 screwed into 4 is rotatably fitted, a connector 10 incorporated in a mounting member 15 is mounted, and the mounting member 15 is fixed to the vehicle panel A in a state where the connector 10 is half-fitted to the connector 1. After that, the bolt 11 rotatably fitted in the connector 10 is screwed and tightened to the nut 4 provided in the connector 1 to connect the wire harnesses W and W ′ to each other, thereby eliminating the conventional problems. It is a thing.

[0006]

The wire harness W arranged on the engine room side is modularized according to the specifications of various devices and switches installed in the vehicle compartment, and the bolt insertion hole 3 is formed at the terminal portion thereof.
The connector 1 having the nut 4 embedded in the open end is attached, and the tip of the connector 1 is fitted and locked in the fitting opening a formed in the vehicle panel A. Next, a bolt 11 that is screwed into the nut 4 provided on the connector 1 is rotatably fitted and inserted into a terminal portion of a vehicle interior wire harness W ′ arranged in various devices and switches, and an instrument panel or the like is attached. The connector 10 incorporated in the attachment member 15 is attached.
Then, the mounting member 15 is screwed and fixed to the vehicle panel A with the tip of the connector 10 half-fitted to the connector 1, and the bolt 1 is rotatably fitted into the connector 10.
By connecting the wire harnesses 1 to the nuts 4 provided on the connector 1 and tightening them to electrically connect the wire harnesses to be connected to each other, the connection work and maintenance / inspection work of the wire harnesses are simplified, and the wire harness The route length of is set to the minimum required length to reduce waste.

[0007]

The method of the present invention will be described below with reference to the drawings. 1 to 3 are explanatory views showing an embodiment of the method of the present invention.

According to the method of the present invention, first, as shown in FIG. 1, one wire harness W to be connected, which is arranged on the engine room side, is connected in accordance with the specifications of various devices and switches installed in the vehicle compartment. A bolt insertion hole 3 is formed through a modularized end portion from the bottom surface of the fitting opening 2 into which the tip portion of the mating female connector 10 is fitted to the base end, and a nut is provided at the open end of the bolt insertion hole 3. Male connector 1 with 4 embedded
The male connector 1 is mounted on the vehicle panel A by fitting and locking the locking projection 4 provided on the outer peripheral surface of the distal end of the male connector 1 to the edge of the fitting port a formed in the vehicle panel A. Install.

Next, at the terminal portion of the wire harness W'connected to various devices and switches installed in the passenger compartment,
A bolt 11 screwed into a nut 4 provided on the male connector 1 is rotatably fitted, and a female connector 10 incorporated in a mounting member 15 such as an instrument panel is attached.

After that, as shown in FIG. 2, the mounting member 15 is screwed to the vehicle panel A with the front end of the female connector 10 half-fitted into the fitting port 2 of the male connector 1. As shown in FIG. 3, a bolt 11 fixed and rotatably fitted in the female connector 10 is screwed into a nut 4 provided in the male connector 1 and the bolt 11 is tightened using a tool such as an impact wrench. As described above, the two connectors 1 and 10 are completely connected, and the wire harnesses W and W'are electrically connected to each other.

As described above, by connecting the one wire harness W to be connected, which is arranged on the engine room side, and the other wire harness W ', which is arranged inside the vehicle compartment, the wire harnesses are connected to each other. The connection can be made extremely easily and quickly, the maintenance and inspection work can be facilitated, and the route length of the wire harness can be minimized to reduce waste.

The male connector 1 is attached to the terminal portion of one wire harness W to be connected arranged on the engine room side, and the terminal portion of the other wire harness W'arranged in the vehicle compartment is described above. The female connector 10 incorporated in the mounting member 15 is attached to the both wire harnesses W, W '.
The method of the present invention is not limited to this, but the female connector 10 is attached to the terminal portion of one wire harness W to be connected arranged on the engine room side. It is also possible to attach the male connector 1 incorporated in the attachment member 15 to the terminal portion of the other wire harness W'arranged in the vehicle compartment and connect the wire harnesses W, W'by the method described above. Of course.

[0013]

As described above, according to the method of the present invention, not only the wire harnesses to be connected can be modularized and the wire harnesses to be connected can be connected by an extremely simple operation of connecting the connectors. The maintenance and inspection work is easy, and the path length of the wire harness can be set to the minimum necessary length, which is extremely economical and has other excellent advantages.
