[embodiment]
Below in conjunction with accompanying drawing the present invention is elaborated:
Plug with creepage protection function; Include shell 1; On shell 1, be provided with SR 11 and testing button 12, on shell 1, also be provided with and import live wire pin 21 and zero line pin 22 that power supply is electrically connected, riveted joint has fixed contact 31 respectively on described live wire pin 21 and zero line pin 22; In shell 1, be provided with fixing body 4; Said fixing body 4 is provided with the movable contact spring 51 that is connected with the out-put supply line, is provided with the moving contact 32 that contacts with fixed contact 31 at an end of described movable contact spring 51, and the other end is fixed on the fixing body 4; In shell 1, also be provided with the trip gear 6 that described fixed contact 31 of control and moving contact 32 are switched on or switched off; Described trip gear 6 includes the cross-arm 61 that is located in the fixing body 4, and described SR 11 is movably arranged in the cross-arm 61 and promotes cross-arm 61 swings, the inclined thrust surface 622 that described SR 11 is provided with trip 621 and cooperates with cross-arm 61; Be arranged with back-moving spring 63 on the top of SR 11, in shell 1, also be provided with the relay assembly 7 that triggers outage by testing button 12.
The standing part that described movable contact spring 51 is fixed on the fixing body 4 forms convex character shape through bending; Because the shape of the standing part of movable contact spring 51 is convex character shape; Can directly insert between two parts, need not riveted joint, go up technology such as tin, just fixing movable contact spring 51; Meet present advanced person's environmental protection assembly technology, thereby reach energy saving purposes.
In described cross-arm 61, be provided with the convexity 611 that cooperates with SR 11; Described SR 11 moves downward to make described inclined thrust surface 622 roof pressures and promote protruding 611 and makes its swing, and described protruding 611 bottom surfaces place trip 621 tops and fasten trip 621.
