2. Description of the Related Art Generally, in various electronic and electrical devices,
Plugs and jacks are typical examples of connection terminals that perform electrical connection by male and female fitting or concave and convex fitting. In many cases,
Insert and remove the plug from the jack provided on the main unit side.

When the plug is removed from the jack and not used, the center conductor pin on the jack side is protected,
Further, in order to prevent foreign substances such as dust from accumulating in the concave portions around the conductor pins, the entire jack may be closed with an open / close cover for protection.

On the other hand, when a slide switch for turning on / off the electrical connection is separately provided in connection with the connection terminal of the plug and the jack, a slide member by a knob operation of the slide switch and the jack described above are connected. Conventionally, it is customary that the protective cover is manufactured completely independently of the protective cover.

[0005]

However, separately manufacturing and providing the sliding member on the slide switch side and the opening / closing cover for protecting the jack is disadvantageous in cost due to an increase in the number of parts and the number of manufacturing steps. In terms of operability, there is an inconvenience that both operations are performed independently.

Therefore, an object of the present invention is to improve the operability by interlocking a linearly operating knob in a slide switch so that an electric connection terminal such as a plug and a jack can be protected from being closed when not in use. An object of the present invention is to provide a slide switch structure capable of reducing costs by reducing the number of parts.

[0007]

A slide switch structure according to the present invention is a slide switch that switches on / off by linearly sliding a switch operation knob protruding from a housing case of an apparatus to a switch body. Having a concave female terminal portion which is an electrical connection terminal disposed in the housing case in the vicinity of the slide switch,
A structure in which a convex male terminal portion is inserted into the concave female terminal portion through an insertion hole provided in the housing case and electrically connected to the concave female terminal portion. A slide plate that moves linearly in a predetermined direction integrally with the operation is provided, and a communication hole is provided to penetrate a protruding tip portion of the slide plate, and the communication hole is formed by movement of the slide plate. And, it is configured so that the convex male terminal portion can be inserted coaxially with each of the insertion holes of the housing case, or the communication hole is shifted to close and protect the concave female terminal portion. ing.

In this case, when the concave female terminal portion is a jack and the convex male terminal portion is a plug, when the slide plate is moved to one end in a predetermined direction by a switch operation knob, the communication hole is connected to the jack. The state of communication with the insertion hole on the housing case side is, for example, a switch-on position. Also,
When the communication hole is displaced from the jack due to the movement of the slide plate, the jack is closed by the slide plate, and a protection state is established.

That is, the slide plate also serves as the conventional jack protection opening / closing cover, and the number of parts can be reduced accordingly.
