Abstract

The invention discloses a safety plug, which comprises a casing, the inner wall of the casing is connected to a rotating shaft through a torsion spring, the upper end of the rotating shaft is fixed with a turntable, and the turntable is connected to the side wall of the casing through rotation. The upper end is inserted with two symmetrical poles, and the inside of the two poles is equipped with an anti-off mechanism, and the ends of the two poles close to the rotating shaft are fixed with conductive poles that pass through the turntable. The inner wall of the housing is rotatably connected with a power-off post which respectively abuts against the two conduction posts through a torsion spring. The advantage lies in: through the volume change caused by the shape change of the electrorheological fluid in the expansion chamber after electrification, the push plate and the push block are pushed, so that the block moves out of the chute to form a protrusion to effectively block the movement of the connecting column , so that the connecting column cannot be separated from the socket, avoiding the separation of the plug and the socket during the power consumption process, and can accept the pull of the outer wall to a certain extent, so that users can feel more at ease without worrying about the plug falling off easily.

Description

technical field [0001] The invention relates to the technical field of plugs, in particular to a safety plug. Background technique [0002] The connectors of general electronic products and the plugs of electrical appliances are called plugs, household AC power plugs and sockets, with rod-shaped or copper-plate-shaped protruding male connectors, which are physically inserted into female connector-type power sockets with slots or recesses. [0003] The plug is generally used in conjunction with the socket to complete the power supply to the electrical appliance. After the plug of the electrical appliance is inserted into the jack during use, it directly contacts the metal reed connected to the zero live wire in the socket. After the reed has been used for a long time Poor contact is prone to occur, which will lead to unstable power connection process or even short circuit, and the existing plug will heat up after long-term use, especially when the power of external electrical...
