Switch device {SWITCH APPARATUS}

The present invention relates to a switch device suitable for use in doors of automobiles and the like.

9 is an exploded perspective view of a conventional switch device, FIG. 10 is related to a conventional switch device, a cross-sectional view showing a terminal plate, and FIG. 11 is a first connection structure of a conventional switch device. 12 is a perspective view showing a second connection structure of a conventional switch device.

9 and 10, the housing 51 is formed integrally with the cover part 51a and the cover part 51a, and is inserted through the central part. It has the threaded part 51c in which the hole 51b was formed.

The operating body 52 inserted through the insertion hole 51b has a cam portion 52a at an end thereof, and an operating body 54 pressurized by the coil spring 53 is provided at the center of the operating body 52. It is inserted, and the cam part 54a of the actuator 54 is in the state engaged with the cam part 52a.

And when the operating body 52 is pressed against the coil spring 53 and pressurized, the operating body 54 is made to rotate by the cam parts 52a and 54a.

The rotating body 56 provided with the movable contact 55 is formed in a spline manner with the working body 54, and is rotated by the rotation of the working body 54. As shown in FIG.

A plurality of terminal plates 58 made of metal plates are embedded in the insulating gas 57.

The terminal plate 58 is formed at each of the contact portion 58a exposed on the upper surface of the insulator gas 57, the terminal portion 58b protruding in a line state from the insulator gas 57, and each of the terminal portions 58b. It has an annular contact part 58c.

And the contact point 58a is contact-separated with the movable contact 55 which rotates, and switching of a contact is made, and this switching signal is derived from the terminal part 58b or the contact part 58c.

In the conventional switch device having such a configuration, as illustrated in FIG. 11, a linear external terminal 59 is connected and connected to the annular contact portion 58c, or bent as shown in FIG. 12. The terminal portion 58b is inserted into the printed circuit board 60 and connected to a conductive pattern (not shown), thereby making the connection of the switch device flexible (for example, Japanese Patent Publication No. 2779951).

However, since the annular contact portion 58c is formed in the connection with the external terminal 59 in the conventional switch device, the processing is cumbersome, the productivity is low, the cost is high, and the annular contact portion 58c is Since they are arranged in parallel in a row, the direction in which the external terminals 59 are plugged becomes constant and there is no flexibility.

In addition, since the contact portion 58c is formed in an annular shape, the spring property is small, the contact with the external terminal 59 is not stabilized, and since the contact portion 58c is exposed outside the housing 51, the dust Etc., the contact became unstable.

In the conventional switch device, as described above, since the annular contact portion 58c is formed in the terminal plate 58, the processing is cumbersome, the productivity is lowered, the cost is increased, and the annular contact portions 58c are in a line. Since they are arranged in parallel with each other, the plugging direction of the external terminals 59 becomes constant, which causes a problem of inflexibility.

In addition, since the contact portion 58c is formed in an annular shape, the spring property is small, the contact with the external terminal 59 is not stabilized, and since the contact portion 58c is exposed outside the housing 51, dust or the like. As a result, there is a problem that the contact becomes unstable.

Therefore, an object of the present invention is to provide a switch device having good productivity, low cost, stable contact, and flexible connection.
