The L-pole conductive ring 13 is provided with an L-pole movable spring 9 and an L-pole plug-in terminal 12 in sequence. The pole conductive ring 14 is sequentially provided with an N pole movable reed 8 and an N pole plug-in terminal 11, between the N pole movable reed 8 and the N pole plug-in terminal 11, the L pole movable reed 9 and the L pole The plug-in terminals 12 are in contact with each other, and the N-pole plug-in terminals 11 and L-pole plug-in terminals 12 are respectively fixedly assembled with the appliance input socket 2;

[0021] The thermal bimetal 4, the porcelain rod ejector 7 and the porcelain rod ejector 7 are each provided with two, the ceramic rod ejector 7 pushes the L pole movable reed 9 and the N pole through the thermal bimetal 4 respectively. Polar reed 8;

[0022] The housing is provided with an N pole reed 22, an L pole reed 23, a third signal reed 24, a second signal reed 19, a first signal reed 20, and a grounding reed 21. Between the second signal reed 19 and the second signal ring 15, between the L pole reed 23 and the L pole conductive ring 13, the N pole reed 22 and the N pole conductive ring 14, the first signal column 10 and the first signal spring The plates 20, the third signal reed 24 and the third signal ring 16, and the ground ring 17 and the ground reed 21 are all in contact with each other. The terminal of the third signal ring 16 is added to the traditional circuit structure. 25. Multi-path function to facilitate power input. The circuit connectors are arranged in the longitudinal direction, and are located in the housing of the corresponding appliance input socket 2 or connector 3 to avoid the misalignment of the opposite reeds and the contact points of the reeds. Displacement, causing no electricity to occur.
