As shown in Fig. 1, Fig. 2 and Fig. 3, in the first embodiment of the safety socket of the present utility model, it includes a socket housing 100, a terminal pin arranged on the socket housing, and the terminal pin includes a live wire terminal pin 110 and a set Fire wire conductive shrapnel 120 on the live wire terminal pin 110; the first embodiment of the safety socket of the present utility model also includes a protection device 200 sleeved on the live wire terminal pin 110, and the protection device 200 includes a protective shell 210, which is arranged in the protective shell The movable connecting block 230 of 210, the spring 220 used for resetting the connecting block 230, and the limit block 240 which limits the movable range of the connecting block. The connecting block 230 is a metal block with a protrusion in the middle, which is a copper block in this embodiment. One side of the protrusion is matched with the live wire pin 310 of the plug 300, and the other side is matched with the live wire conductive shrapnel 120. The connecting block 230 is rotatably connected with the protective shell 210 The two sides of one end of the connection block 230 are provided with a protrusion 233 used as a rotating shaft, and the protective shell 210 is provided with a turntable 211 that cooperates with the protrusion, and the other end is resisted by the spring 220 set in the protective shell 210 to limit the position. Block 240 on. When the plug 300 is inserted into the socket housing 100, under the push of the live wire pin 310, the connection block 230 moves toward the live wire conductive shrapnel 120, and finally contacts the live wire conductive shrapnel 120, and conducts the live wire pin 310 and the live wire conductive shrapnel 120; When going out, under the action of the spring 220, the connection block 230 resets. This design ensures that the connection block 230 and the live wire conductive shrapnel 120 can be connected only under a certain force, and lightly touching the live wire jack will not cause an electric shock, which increases the safety of the socket.
