Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to a plug for preventing electric shock. Background Art

[0002] Plugs are the connectors of general electronic products and the plugs of electrical appliances. They mainly serve to electrically connect electrical appliances to sockets and are standard equipment for powered devices.

[0003] The main function of the existing plug is electrical connection, and the main protection against electric shock is still through leakage protection of leakage protector. However, the plug still has a major safety hazard. Due to the long length of its contacts, it is easy for the hand to slip and come into contact with the contacts when unplugging, thereby causing contact failure. At the same time, infants and young children may cause electric shock accidents due to misuse of the plug without the guidance of a guardian. Since the current tentacles of the plug lack effective protection, infants and young children may eventually be electrocuted after inserting the plug into the socket. In view of this, we propose a plug to prevent electric shock. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a plug for preventing electric shock, which can solve the problem that the existing plug is insufficiently protected and causes electric shock to infants and young children.

[0006] Preferably, the unlocking assembly includes two unlocking buttons, and the two unlocking buttons are respectively slidably connected to the inside of the two second receiving grooves, and the inner walls of the two second receiving grooves are respectively provided with third receiving grooves.

[0007] Preferably, one side surface of the two unlocking buttons that is adjacent to each other is respectively fixedly connected with an unlocking block, and one side surface of the two unlocking blocks that is adjacent to each other is fixedly connected with a return spring.

[0008] Preferably, the adjacent ends of the two return springs are respectively fixedly connected to the inner walls of the two third receiving grooves, and the right side surfaces of the two unlocking blocks are each provided with a second U-shaped sliding groove.

[0009] Preferably, the trigger plate is adapted to the receiving groove, a second return spring is fixedly connected to the left surface of the trigger plate, and a left end of the second return spring is fixedly connected to the inner wall of the receiving groove.

[0010] Preferably, a sliding groove is provided on the right side surface of the plug body, the T-shaped connecting plate is slidably connected to the sliding groove, and a protective collar is fixedly connected to the left side surface of the plug body, and a hole is provided on the surface of the protective collar.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The plug for preventing electric shock, when the plug body needs to be used to connect the socket, the user pinches the plug body with fingers, and the unlocking component is automatically pressed when pinching, thereby canceling the restriction on the U-shaped protective plate. Then, the metal pin is aligned with the socket hole and inserted. When inserted, the trigger plate contacts the socket, thereby causing the trigger plate to move to the left, and then the two U-shaped protective plates are driven to move to the left by the T-shaped connecting plate and enter the inside of the U-shaped slide groove. After insertion, the unlocking component is released. When pulling out, the user pinches the unlocking component again. When pulling out, the subsequent structure pushes out the U-shaped protective plate and covers the metal pin. Through the above structure, when the plug body is plugged in or out, the surfaces on both sides of the metal pin are blocked by the U-shaped protective plate, thereby preventing the metal pin from contacting with the hand due to slippage or other factors, thereby preventing electric shock accidents. The safety of the plug body is effectively improved and the possibility of electric shock accidents is reduced.

[0013] (2) The plug for preventing electric shock has a trigger plate that will compress the second return spring synchronously when inserted. After the insertion is completed, the unlocking button is released, and the unlocking block is reset under the action of the return spring. After the unlocking block moves a short distance, it is blocked by the U-shaped protective plate and cannot be reset. At the same time, the unlocking block will also use friction to limit the U-shaped protective plate. When the plug body is pulled out, the unlocking button is pressed again to move the unlocking block, and then the U-shaped protective plate is pushed out again in cooperation with the second return spring. Through the above structure, not only can the contact with the metal pin be avoided during plugging and unplugging, but the two unlocking buttons can also be used to prevent infants and young children from accidentally inserting the plug body into the socket, thereby reducing the probability of accidents. At the same time, the protective ring can be used to limit the twisting angle of the cable, thereby extending the service life of the cable. BRIEF DESCRIPTION OF THE DRAWINGS
