Electromagnetic socket and magnetic plug

Abstract

The invention relates to an electromagnetic socket and magnetic plug. The electromagnetic socket comprises a socket base, a socket contact, a magnetic conversion circuit and a touch switch, wherein the socket contact is arranged in the socket base, the socket is matched with the magnetic plug, the magnetic conversion circuit is arranged in the socket base, and the touch switch is arranged on the surface of the socket base. By the aid of the electromagnetic conversion circuit on the socket and a magnetic area arranged on the plug, the problem of loosening of the plug and the socket is solved by the aid of the principle that unlike poles attract each other while like magnetic poles repel each other in magnetism is solved, and the plug is conveniently pulled out of the socket. In addition, electromagnetic polarity and magnetic strength can be conveniently changed by the aid of the touch switch arranged on the socket, and the magnetic conversion circuit can be controlled to be in a nonmagnetic state, so that energy is saved.

Description

technical field [0001] The invention belongs to the technical field of switches, and in particular relates to an electromagnetic socket and a magnetic plug. Background technique [0002] Most of the plugs and sockets used at present rely on the metal posts or inserts on the plug to be inserted into the metal holes of the socket to realize the connection of the power cord. There is no mutual fixing device in this connection mode, and only rely on the elasticity of the elastic element of the socket to clamp the plug or the friction force between the socket and the plug to clamp the plug. After long-term use, once the elasticity of the elastic element decreases, or the friction between the jack and the plug decreases, it will cause poor contact between the pin and the socket or the plug will fall off. [0003] In order to prevent the phenomenon that the elastic element cannot clamp the plug tightly or even the plug during use, when designing plugs and sockets, the elasticity o...

Problems solved by technology

[0004] However, when using high power, due to the existence of the contact resistance between the plug and the elastic element, the contact resistance between the socket and the wire, a certain amount of heat will be generated, resulting in the thermal expansion of the structure of the plug and the socket, coupled with the suction force of the magnet, it is difficult for the plug to be removed from the socket. unplugged from the socket
