Electric leakage protection socket

Abstract

The invention discloses an electric leakage protection socket, which comprises a base and a cover plate for sealing an opening of the base, and is characterized in that the base is provided with a movable contact spring, a wiring terminal for being electrically connected with an external power line, a circuit board electrically connected with the wiring terminal, and a switching mechanism for driving the movable contact spring to be in contact with or separated from the wiring terminal; the circuit board is electrically connected with a transmission mechanism used for locking or unlocking theswitch mechanism, the movable contact spring is electrically connected with a plug bush, the cover plate is provided with a cover plate jack used for inserting a pin of a plug into the plug bush, andthe circuit board is further electrically connected with a mutual inductor used for detecting whether the socket leaks electricity or not. The electric leakage protection function is integrated on thesocket, automatic power-on and power-off of the socket are achieved through the switch mechanism and the transmission mechanism, the structure is simple, operation is convenient, a good electric leakage protection effect on an electric appliance is achieved, and practicability is high.

Description

[technical field] [0001] The invention relates to a leakage protection socket. [Background technique] [0002] Leakage protection plugs are widely used and can be used for leakage protection of various electrical equipment, with high safety performance, which can avoid damage to electrical equipment and reduce the occurrence of safety accidents. However, due to the high cost of leakage protection plugs, it is not suitable for all electrical plugs to be made into leakage protection plugs. Leakage protection plugs are generally large in size and will occupy a whole socket when in use, which greatly hinders the use of other electrical appliances. And some electrical appliances that are already in use are inconvenient to replace the ordinary plug with the leakage protection plug, but these electrical appliances also need the leakage protection function. [0003] The present invention is produced based on the above problems. [Content of the invention] [0004] The purpose of...
