[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
A kind of plug with creepage protection function; include shell 1; be provided with reset button 11 and testing button 12 at shell 1; on shell 1, also be provided with the live wire pin 21 and the zero line pin 22 that are electrically connected with input power; 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; be provided with the movable contact spring 51 that is connected with the out-put supply line at described fixing body 4; end at described movable contact spring 51 is provided with the moving contact 32 that contacts with fixed contact 31; the other end is fixed on the fixing body 4; in shell 1, also be provided with the trip gear 6 that the 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; described reset button 11 is movably arranged in the cross-arm 61 and promotes cross-arm 61 and swings; the inclined thrust surface 622 that is provided with snap fit 621 and cooperates with cross-arm 61 in described reset button 11; be arranged with back-moving spring 63 on the top of reset button 11, in shell 1, also be provided with the relay assembly 7 that is triggered 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 by 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 the techniques such as riveted joint, upper tin, fixing movable contact spring 51 just, meet present advanced person's environmental protection assembly technology, thereby reach energy-saving and cost-reducing purpose.
