Safety plugging-connection mechanism for electrical appliance energization

Abstract

The invention provides a safety plugging-connection mechanism for electrical appliance energization. The safety plugging-connection mechanism comprises a plugging-connection seat and a plugging-connection head; a sliding-connection cavity is defined in the plugging-connection seat; plugging-connection grooves which are communicated with the outside and are distributed symmetrically in a vertical direction are formed in the right end surface of the sliding-connection cavity; a sliding-connection frame is mounted in the sliding-connection cavity in a leftward-and rightward-slideable manner; through grooves which extend in a left-and-right direction and are distributed symmetrically in a vertical direction are formed in the sliding-connection frame; a threaded rod is mounted in the sliding-connection frame through screw-thread fit; the right end of the threaded rod is rotatably installed in the right end wall of the sliding-connection cavity; the left end of the threaded rod is in matchedconnection with a motor fixedly installed in the left end wall of the sliding-connection cavity; first grooves which are symmetrically arranged in a vertical direction are formed in the left end wallof the sliding-connection cavity; power supply blocks connected with mains supply are fixedly mounted in the first grooves; plugging-connection openings facing the sliding-connection frame are formedin the power supply blocks; conductive blocks which are matched with the plugging-connection openings and are symmetrically distributed in a vertical direction are arranged on the left end surface ofthe sliding-connection frame; elastic conductive blocks are fixedly mounted in the inner side end walls of the plugging-connection grooves; second grooves are formed in the outer side end surfaces ofthe through grooves; and contact switches connected with the motor are mounted in the second grooves.

Description

Technical field [0001] The invention relates to the field of electrical appliances for household appliances, in particular to a safety plug-in mechanism for electrical appliances. Background technique [0002] Since electricity has entered human life for more than 200 years, it has brought great convenience to people’s lives. In modern home life, the number of electrical appliances is also increasing. When in use, electrical appliances need to be powered on before they can run. The connector and the socket are matched to complete. In the traditional socket, the power supply sheet is almost exposed in the socket. Therefore, this kind of power supply sheet is easy to be touched by the outside metal rod, due to the curiosity of young children , They will use some metal rods to insert into the socket, and the metal rod will contact the power supply sheet when inserted into the socket. Therefore, accidents will occur. The accident will cause tissue damage and dysfunction. In severe ca...

[0002] Since electricity has been in human life for more than 200 years, it has brought great convenience to people's life. In modern home life, the number of electrical appliances is also increasing. When electrical appliances are in use, they need to be powered on before they can run. Electrical appliances rely on plug-in The cooperation between the connector and the socket is completed. In the traditional socket, the power supply piece is almost exposed in the socket slot. Therefore, this power supply piece is easy to be touched by the external metal rod. Due to the curiosity of young children , they will use some metal rods to insert into the sockets, and the metal rods will be in contact with the power strips when inserted into the sockets, so accidents will occur, which will cause tissue damage and dysfunction, and heartbeat in severe cases and respiratory arrest, therefore, the traditional socket has a great potential safety hazard; and when the traditional power supply socket cooperates with the power supply plug, it only relies on the clamping of the power supply sheet to maintain the power supply state, but this state is not stable enough. When someone accidentally touches the power plug or the wire, it will cause the power plug to loosen or fall off. Therefore, it will cause an unexpected power outage and easily affect the home appliances.
