Description
Technical field
The utility model relates to a kind of switch, particularly relates to a kind of flame-proof switch.
Background technology
At present, its contact of common electric switch all communicates with air, if this kind of switch is when there being the occasion of flammable and explosive substance electrically to cut off, because its contact can produce electric spark, so time when electrically switching be and danger, very dangerous, easy appearance blast, the hidden danger that fire etc. are large, had a strong impact on the useful life of electric switch, security performance is low.Therefore, for solving the problem, spy provides a kind of new technical scheme to meet the demand of people.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of flame-proof switch, simplicity of design, and fail safe is high.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flame-proof switch, comprise panel, conducting strip, described panel is provided with shift knob, described shift knob is connected with described conducting strip by a guide rod, the back of described panel is provided with terminal box, described terminal box is provided with binding post, the back of described panel is provided with conductive contact, described conductive contact is connected with described binding post, a U-type groove is connected with bottom described terminal box, the bottom of described U-type groove offers the first connecting hole, supporting bracket is provided with in described terminal box, position corresponding with described first connecting hole in described supporting bracket is provided with the second connecting hole, elastic supporting member for supporting optical member is provided with between described first connecting hole and described second connecting hole, be connected by described elastic supporting member for supporting optical member between described conducting strip with described terminal box.
Further, the upper end of described elastic supporting pipe is provided with locating piece, and the bottom of described locating piece and conducting strip is inconsistent.
Further, the quantity of described conductive contact and described binding post is 2.
Further, described terminal box outer wrap has one deck resin glue.
Further, described guide rod is hollow metallic rod.
The advantage that the utility model has and good effect are: the utility model effectively solves the situation of loose contact, sparking and blast, ensure that the safety of the person and electrical equipment.
