[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0035] One aspect of the present invention provides an anti-electric shock socket, comprising: a shell assembly, a terminal 52, a rotating arm 59, a plug connection clip, and an elastic reset element 63, wherein the plug connection clip and the elastic reset element 63 are fixedly installed in the shell assembly, the rotating arm 59 is rotatably connected to the plug connection clip, the rotating arm 59 includes a first end for mating with a plug, and a second end for conductively connecting or disconnecting with the terminal 52, when the plug is not inserted into the plug connection clip, the rotating arm 59 is acted upon by the elastic reset element 63 to disconnect the second end from the terminal 52, and when the plug is inserted into the plug connection clip, the rotating arm 59 overcomes the action of the elastic reset element 63 to conductively connect the second end to the terminal 52. The plug connection clip, the rotating shaft 60, the rotating arm 59, the contact 41, and the elastic reset element 63 constitute the electrical connection component 20 of the first embodiment; the plug connection clip, the rotating shaft 60, the rotating arm 59, the elastic reset element 63, the movable spring 62, and the contact 41 constitute the electrical connection component 20 of the second embodiment.

[0036] Please refer to Figure 5 , 7 , 10, 13, when the plug is not inserted, under the action of the elastic reset element 63, a pressure is applied to the rotating arm 59, so that one end of the rotating arm 59 is pressed. Since the rotating arm 59 is rotatably arranged, the other end of the rotating arm 59 is lifted up and disconnected from the terminal 52.

[0037] Please refer to Figure 6 , 8 , 11, 14, when the plug is inserted, the plug is inserted into the plug connecting clip and is in conductive contact with it. Under the action of the plug, the elastic force of the elastic reset element 63 is overcome, so that the left end of the rotating arm 59 is lifted upward. Since the rotating arm 59 is rotatably arranged, the other end of the rotating arm 59 moves downward and is in conductive contact with the terminal 52 directly or indirectly.

[0038] Due to the adoption of the above technical solution, the present invention uses the elastic reset element 63 to keep the rotating arm 59 and the terminal 52 in a normally open state. Only when a standard plug is inserted can the rotating arm 59 rotate and make conductive contact with the terminal 52 to achieve electrical conduction. The use of foreign objects or iron wires cannot make the contacts come into place, thereby achieving an anti-electric shock function.

[0039] exist Figure 5-6In the first embodiment shown in Figures 9-11, the present invention can achieve connection or disconnection with the terminal 52 only by the lever movement of the rotating arm 59. When the plug is inserted, the rotating arm 59 moves clockwise around the rotating shaft 60, so that the contacts on the rotating arm 59 contact the contacts 41 on the live wire fixing spring 40 and the contacts 41 on the neutral wire fixing spring 39 respectively, so that electricity is connected. When the plug is inserted, the elastic reset element 63 is compressed backward; when the plug is pulled out, the elastic reset element 63 makes the highest part of the arc surface on the rotating arm 59 fit to one side of the plug connection clip, so that the rotating arm 59 moves in the direction away from the two contacts, so that electricity is disconnected. One side of the rotating shaft 60 adopts a stamping and flanging process, and has a stamping flanging 61 at the end of the rotating shaft to prevent the rotating shaft from coming out.

[0040] In the first embodiment, the rotating arm 59 is connected to the plug connection clip through the rotating shaft 60, and the existence of the movement gap may cause a potential problem of unreliable electrical conduction. Figure 7-8 In the second embodiment shown in 12-14, preferably, the anti-electric shock socket further comprises a movable spring piece 62 which is conductively connected to the plug connection clip, one end of the movable spring piece 62 is fixedly mounted in the housing assembly, and the second end of the rotating arm 59 presses the movable end of the movable spring piece 62 to be conductively connected to the terminal 52. When the plug is inserted, the rotating arm 59 moves clockwise around the rotating shaft 60, thereby driving the movable spring piece 62, so that the contacts on the movable spring piece 62 contact the contacts 41 on the live wire fixed spring piece 40 and the contacts 41 on the neutral wire fixed spring piece 39, respectively, so that electricity is turned on. When the plug is inserted, the elastic reset element 63 is compressed backward; when the plug is pulled out, the elastic reset element 63 makes the highest part of the arc surface on the rotating arm 59 fit to one side of the plug connection clip, so that the movable spring piece moves in the direction where the two contacts are away from each other, so that electricity is disconnected.
