Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a switch having a connection terminal connected to a connector for harness connection.

[Conventional technology]

A conventional switch of this type is, for example, Shoukaisho 63-269.
There is one disclosed in Japanese Patent Publication No. 35-35.

This is mounted on the lower surface of a rotor that is rotatably pivoted in a cylindrical case so that a movable contact consisting of a downwardly bulging leaf spring is attached so as to rotate integrally with the rotor.
In addition, the fixed contact is fixed to the bottom surface of the case so as to face the movable contact, and at the end of the fixed contact, the connection terminal protruding from the foot portion extended and formed on the case is continuously provided. By wiring to the drive device, when the movable contact rotates and comes into contact with the fixed contact at an arbitrary position, the fixed contact conducts and is turned on to drive the drive device.

[Problems to be solved by the device]

However, in the case of the conventional switch as described above, when connecting the harness to the switch, the copper wire of the harness has to be connected by soldering to the connection terminal protruding from the foot of the case. Was being lowered.

In order to improve the work efficiency of the connection, for example, it is conceivable to integrally form a connector for connecting the harness connector to the switch with one touch. However, since the connector is extremely complicated in shape,
Since there are a plurality of directions in which the mold for resin molding is removed, the shape of the mold becomes complicated, resulting in an increase in cost, which is not practical.

Therefore, when the case and the connector are integrally formed, in order to fix the fixed contact and the connection terminal to the switch by insert molding so as to be integrated with the case, the resin molding die becomes more complicated. Since it is difficult, after molding the case into a predetermined shape, it is necessary to fit the fixed contact and the connection terminal to the predetermined mounting position and fix them with an adhesive, which results in poor work efficiency. Since the fixed position is not fixed, there is a problem that the detection accuracy is affected.

SUMMARY OF THE INVENTION In view of the above problems of the conventional technique, the present invention enables a switch and a harness connector to be easily connected, and a fixed contact to be easily and reliably fixed to a case. An object of the present invention is to provide a switch provided with such a connection terminal.
