Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a vehicle combination switch mounting structure in which various switch units such as a headlight switch and a wiper switch are detachably mounted on a base arranged on a steering column of a vehicle.

[0002]

[Prior Art]

 Conventionally, as a mounting structure for a vehicle combination switch of this type, for example, the technique disclosed in Japanese Utility Model Publication No. 64-354 is generally used. This is to install a plurality of switch units, each of which has a multi-pole connector connected by a connecting wire, in a detachable manner from the side of the housing.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, each switch unit is provided with a multi-pole connector, and each switch unit is connected to an external wiring, which causes a problem of increasing the number of connection steps. In order to solve such a problem, a turn signal switch or the like is built in the column body and a wiper switch unit is detachably attached to the column body, as in the technique disclosed in Japanese Utility Model Laid-Open No. 57-36634. A configuration may also be considered in which both are connected by a connector. However, the switch built into the column body is extremely difficult to repair or replace while it is connected to the steering shaft.

In recent years, as in the technique disclosed in Japanese Utility Model Laid-Open No. 2-79534, a control circuit unit for performing load control based on a switch signal of each switch is attached to a column body which is a switch body. It's coming. Therefore, like these conventional technologies, the range of connection with external wiring is wide, and even if individual external wiring is connected or only a specific part is connected with a connector, the number of connection steps with external wiring is increased. It cannot be prevented. The present invention has been made in view of the above problems, and an object of the present invention is to provide a mounting structure for a vehicle combination switch, which reduces the number of connection steps for connecting to external wiring.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention detachably mounts a switch unit and a control circuit unit for performing load control based on a switch signal of the switch unit on the base, and the switch unit includes the base. A combination switch mounting structure for a vehicle, characterized in that it is connected to the control circuit unit with a connector in conformity with a mounting direction to the control circuit unit, and the control circuit unit has a connector for connecting to external wiring. ..

【Example】

 A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Reference numeral 1 is a base plate, and a through hole 1a is formed at a central position for inserting into a steering column (not shown) of the vehicle. The base 1 has a pair of side walls 1b and 1b and an upper upper plate 1c in a substantially U shape so as to form a space for inserting the two switch units 3 and 4 from the left and right lateral directions in FIG. Is forming. A pair of guide grooves 1d, 1d facing each other is formed on the inner wall surface of each side wall 1b, 1b in the direction in which each switch unit 2, 3 is mounted. On the other hand, a pair of guide ridges 2a, 2a or 3a, 3a fitted in the guide grooves 1d, 1d are provided on the outer wall surfaces of the switch units 2, 3 so as to project therefrom.

Further, the side walls 1b and 1b of the board 1 are provided with a pair of screw holes 1e and 1e, respectively, at end faces of the switch units 2 and 3 in the mounting direction. The switch units 2 and 3 are provided with flange portions 2c and 3c provided with through holes 2b and 3b which match the screw holes 1e and 1e, respectively. Therefore, each switch unit 2 and 3 is guided by inserting the guide ridges 2a and 3a into the guide grooves 1d 1 and 1d, and is attached to the base 1 by tightening the set screw 4 and the screw holes 1e and 1e. To be done. As a result, the switch units 2 and 3 are detachably attached to the base 1.

Here, the first switch unit 2 has, for example, a wiper switch, a washer switch, etc. built therein, and a switch signal is output from the switch connector 2e fixed to the upper portion by operating the switch with the lever 2d. .. Further, the second switch unit 3 has, for example, a headlight switch, a direction indicating switch, etc. built therein, and a switch signal is output from the switch connector 3e fixed to the upper portion by operating the switch with the lever 3d. The switch connectors 2e and 3e are arranged in the mounting direction of the first and second switch units 2 and 3.

A control circuit unit 5 is fixed to the inside of the upper plate 1c of the base 1 with a set screw 6. Therefore, the control circuit unit 5 is detachably attached to the board 1. This control circuit unit 5 uses a transistor, a relay, etc. to control various loads (not shown) such as a wiper motor, a headlight, and a direction indicator light based on the switch signals of the first and second switch units 2 and 3. The built-in electronic circuit 5a is composed.

On the lower surface of the control circuit unit 5, the input side connectors 5b and 5c for connecting the switch connectors 2e and 3e of the first and second switch units 2 and 3 and the connector 7a of the external wiring 7 are connected. The output side connector 5d is fixed. Each of the connectors 5b to 5d is electrically connected to the electronic circuit 5a. The first and second switch units 2 and 3 match the mounting direction to the board 1 and connect the switch connectors 2e and 3e to the input side connectors 5b and 5c. The external wiring 7 is connected to the above various loads.

Next, a procedure for assembling the vehicle combination switch having the above configuration will be described. First, the control circuit unit 5 is attached to the inside of the board 1 with the set screw 6. After that, the guide grooves 1d, 1d and the guide ridges 2a, 3a are guided from the lateral direction of the base 1, and the first and second switch units 2, 3 are inserted. Then, in the process of inserting the first and second switch units 2 and 3, the switch connectors 2e and 3e are connected to the input side connectors 5b and 5c. The first and second switch units 2 and 3 are attached to the base 1 with screws 4 via the flange portions 2c and 3c. The vehicle combination switch thus assembled is installed in the steering column of the vehicle. Then, the connector 7a of the external wiring 7 is connected to the output side connector 5d.

In the vehicle combination switch assembled in this way, the switch signals output from the switch units 2 and 3 based on the operation of the levers 2 d and 3 d are the switch connectors 2 e and 3 e and the input side connector 5 b. Input to the electronic circuit 5a via 5c. Then, the control signal of the electronic circuit 5a is output to various loads through the external wiring 7 through the output side connector 5d and the connector 7a of the external wiring 7.

[Effect of the device]

 As described above in detail, according to the configuration of the present invention, when the detachable switch unit is mounted on the base, it is simply and quickly connected to the control circuit unit mounted on the base by the connector. Then, the control signals collected by the control circuit unit are connected to the external wiring by a single output connector. Therefore, only one connection with the external wiring is required, and the number of connection steps is reduced. In addition, since each switch unit has no connection line to the external wiring, the assemblability to the board is improved.
