[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is based on the concept that 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.
The present invention relates to an improvement in a mounting structure of a vehicle combination switch.

[0002]

2. Description of the Related Art Conventionally, as a mounting structure of a vehicle combination switch of this type, for example, Japanese Utility Model Publication No. 64-3
No. 54, the technology of which is generally used. In this method, a plurality of switch units each having a multi-pole connector connected by a communication line are detachably mounted from a lateral direction of a housing.

[0003]

However, in the above-mentioned conventional technology, each switch unit is provided with a multi-pole connector, and each switch unit is connected to an external wiring.
There is a problem that the number of connection steps increases. 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 mounted on the column body, as in the technique according to Japanese Utility Model Application Laid-Open No. 57-36634. A configuration in which the two are connected by a connector is also conceivable. However, the switch built in the column body is very difficult to repair or replace when connected to the steering shaft.

In recent years, a control circuit unit for performing load control based on a switch signal of each switch has been mounted on a column body which is a switch body, as disclosed in Japanese Utility Model Laid-Open Publication No. 2-79534. Have been. Therefore, as with these conventional technologies, the range of connection with external wiring is wide, and even if the connection is made individually to external wiring or only a specific part is connected with a connector, an increase in the number of connection steps with external wiring is prevented. Can not. The present invention has been made in view of the above problems, and has as its object to provide a mounting structure for a vehicle combination switch in which the number of steps for connecting to an external wiring is reduced.

[0005]

According to the present invention, in order to achieve the above object, two left and right switch units, a load control based on switch signals of the switch units, and
And a control circuit unit ing from the case body by interposing an electronic component mounting board in central cross section is detachably mounted on the upper plate of a substantially U-shaped base, said control circuit unit, its
The switch unit in the left and right openings of the base
An input connector for connecting to a vehicle is disposed facing the input connector, and an output connector for connecting to an external wiring is provided.

d is formed. On the other hand, a pair of guide ridges 2a, 2a or 3a, 3a to be inserted into the guide grooves 1d, 1d are provided on the outer wall surfaces of the switch units 2, 3, respectively.

The side walls 1b, 1b of the base 1 are provided with a pair of screw holes 1e, 1e on the end faces of the switch units 2, 3 in the mounting direction. Each of the switch units 2, 3 has a flange 2c, 3c provided with a through hole 2b, 3b corresponding to each screw hole 1e, 1e. Accordingly, the switch units 2 and 3 are guided by fitting the guide ridges 2a and 3a into the guide grooves 1d and 1d, and are mounted on the base 1 by screwing the set screw 4 and the screw holes 1e and 1e. Is done. As a result, the switch units 2 and 3 are detachably mounted on the base 1.

Here, the first switch unit 2 incorporates, for example, a wiper switch and a washer switch,
By performing a switch operation with the lever 2d, a switch signal is output from the switch connector 2e fixed to the upper portion. The second switch unit 3 includes, for example, a headlight switch and a direction indicating switch, and outputs a switch signal from a switch connector 3e fixed to an upper portion by operating a switch with a lever 3d. The switch connectors 2e, 3e are arranged in the mounting direction of the first and second switch units 2, 3.
