BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle electric wire connecting device for connecting a signal line and a power supply line of an optional circuit to an existing signal line and a power supply line.

[0002]

2. Description of the Related Art A conventional method for connecting a signal line and a power supply line of an option circuit to an existing signal line and a power supply line is shown in FIG.
This will be described with reference to FIG. The power line 3 (3-1, 3-1) of the conventional vehicle
3-2 ...) from the power supply box 1 and the signal line 4 (4-
1, 4-2...) Connect required devices via a connection box 2 or the like. Therefore, when the dealer requests that the optional circuit be attached to the vehicle, the power supply line and the signal line required for the optional circuit from the standard power supply line 3 and the signal line 4 shown in FIG. The processing is performed to take out the optional circuit wires 5.

[0003]

As described above, the connection of the power supply line and the signal line of the conventional optional circuit is performed by selecting the necessary power supply line and the signal line provided in the vehicle and performing splice processing. I try to connect.
This work had to be performed in the vehicle actually equipped, and the mounting work was very difficult. SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric wire connecting device for a vehicle which can easily connect a power supply line and a signal line of an optional circuit.

[0004]

According to a first aspect of the present invention, there is provided a vehicle electric wire connecting apparatus for connecting a signal line and a power supply line of an option circuit to an existing signal line and a power supply line. A connector for detachably attaching at least one of the terminals of the existing electric wire, and a detachable intermediate connector provided between the electric wires connected to the connector. One end of the existing electric wire is made to be a detachable connector connection, and a detachable intermediate connector is provided in the middle of the electric wire connected to the connector. The wire can be easily selected and spliced.

In the second invention, the connector and the intermediate connector are separated into a power line and a signal line. Since the electric wires connected to the connector and the intermediate connector are separated into a power supply line and a signal line, it is easy to select necessary electric wires.

In a third aspect of the present invention, the wires connected to the connector and the intermediate connector are only wires that are expected to be used in an optional circuit in advance. Since only the wires expected to be used in the optional circuit are connected to the connector and the intermediate connector in advance, the number of wires is reduced, and the required wires can be easily selected. A connector with a small number of connections can be used.

In a fourth aspect of the present invention, the electric wires connected to the connector and the intermediate connector include electric wires used only for optional circuits. Since the electric wire used only for the optional circuit is included between the connector and the intermediate connector in advance, the connection of the electric wire of the optional circuit can be all performed by splicing between the connector and the intermediate connector.

[0008] In a fifth aspect of the present invention, a second intermediate connector is provided which is detachable from an electric wire connected to the connector and the intermediate connector. Since the second intermediate connector is provided between the connector and the intermediate connector, the connection between the second intermediate connector and the intermediate connector can be taken out, and the connection of the wires of the optional circuit can be performed at the optimum connection position. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific example of the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a configuration diagram of an embodiment of the present invention. In FIG. 1, 1 is a power supply box, and 2 (2-
1, 2 and 2) are connection boxes, 3 is a power line, 4 is a signal line, 5 is an optional circuit wire, and 6 (6-1, 6-2).
Is a connector, and 7 (7-1, 7-2) is an intermediate connector.

The power supply lines 3 (3-1, 3-2...) And the signal lines 4 (4-1, 4-2...) Are previously separated into wires required by various optional circuits and wires not required. . FIG. 1 shows a case where required power supply lines are 3-2, 3-5 and 3-6, and required signal lines are 4-2 and 4-4.

These required electric wires are separated into a power supply line and a signal line, and detachable connectors 6-1 and 6-2 are provided on at least one of the terminals to provide a power supply box 1, a connection box 2, etc. Connect to The electric wires connected to the connectors 6-1 and 6-2 are provided with detachable intermediate connectors 7-1 and 7-2 between the electric wires.

When there is a request for an optional circuit and it becomes necessary to connect the wires of the optional circuit, the middle of the wire group is pulled out of the mating connector by pulling out the connector 6 and the intermediate connector 7 as shown in FIG. The optional circuit wire 5 is spliced to the wires required for the wires (power supply line 3 or signal line 4) connected to the connector 6 and the intermediate connector 7 taken out when the connection is completed. Return to the previous position and connect both connectors 6,7.

[0013] Between the connector 6 and the intermediate connector 7,
As shown in FIG. 3A, if there is a dedicated line used only for the optional circuit, the dedicated line 8 for the optional circuit is also connected in advance. By doing so, it is possible to simultaneously connect the wires of the optional circuit.

Further, as shown in FIG. 3B, a second intermediate connector 9 may be connected between the connector 6 and the intermediate connector 7. By providing the second intermediate connector 9 in this manner, the connection position between the second intermediate connector 9 and the intermediate connector 7 is free, and the second intermediate connector 9 and the intermediate connector 7 can be provided at an optimal position for electric wire connection of an optional circuit.

[0015]

As described above, according to the present invention, the following effects can be obtained. Since one of the terminals of the existing electric wire is made to be a detachable connector connection, and a detachable intermediate connector is provided in the middle of the electric wire connected to the connector,
The connector and the intermediate connector can be taken out at a position having better workability than the mounting position, and the selection and splicing of the electric wire can be easily performed (claim 1).

According to the second aspect of the present invention, since the electric wires connected to the connector and the intermediate connector are separated into the power supply line and the signal line, the required electric wires can be easily selected. According to the third aspect of the present invention, since the wires connected to the connector and the intermediate connector are only wires that are expected to be used in the optional circuit in advance, the number of wires is reduced, and the required wires are reduced. A connector that can be easily selected and that has a small number of connections can be used.

Further, according to the invention of claim 4, since the electric wire used only for the optional circuit is previously included between the connector and the intermediate connector, the connection of the electric wire of the optional circuit is performed by a splicing process between the connector and the intermediate connector. Everything can be done. According to the fifth aspect of the present invention, since the second intermediate connector is provided between the connector and the intermediate connector, it is possible to take out the space between the second intermediate connector and the intermediate connector, and to connect the wires of the optional circuit. Can be performed at the optimum connection position.
