Leakage protection socket

Abstract

The invention provides a leakage protection socket which comprises a shell, output conductors, power input ends, power output ends, a resetting button and an electromagnetic tripping mechanism, wherein a main loop switch comprises a pair of movable metal sheets; the movable metal sheets are elastically arranged in a clamping piece in a penetrating manner; a positioning base plate is arranged below the clamping piece; a convex ridge and a limiting groove are arranged and formed between the clamping piece and the positioning base plate; movable contact ends are arranged on the two sides, extending out of the clamping piece, of the movable metal sheets; the output conductors and the power input ends are led out to form fixed contact ends; the power output ends are led out to form fixed contact ends; the electromagnetic tripping mechanism comprises an iron core, a lock catch and a tripper; the iron core is provided with a driving disk and a lifting piece; a lifting piece window is provided with a slope and rib slots; the movable metal sheets are clamped in the lifting piece rib slots. The leakage protection socket has the beneficial effects that the clamping piece drives the movable metal sheets to swing, and the operation is successful and reliable; no transitional conductive element is needed, and the processing cost is low; the resetting button is pressed down to turn on the main loop switch, and the operation is quick and stable.

Description

technical field [0001] The invention relates to the field of power sockets, in particular to a leakage protection socket. Background technique [0002] Existing leakage protection sockets, for example (invention patent with patent number 201010248157.8), generally include a housing, an output conductor, a power input terminal, and a power output terminal, which are used to close the main circuit switch and cooperate with the locking mechanism to maintain the closed state of the main circuit switch. Furthermore, the reset button that keeps the power supply input terminal, the power supply output terminal and the output conductor conducting, and the electromagnetic tripping mechanism used to disconnect the main circuit switch when a leakage current is generated, etc., the metal sheets drawn from the input terminal and the output terminal must be at least one For the elastic metal sheet, the length of the elastic metal sheet is long and one end is positioned and the other end i...

AI Technical Summary

Problems solved by technology

The mains power supply includes neutral wire and live wire. The elastic metal sheets must appear in pairs. It is difficult to achieve the same bending degree of the two elastic metal sheets during processing, and the repeated elastic lifting of the free end will easily lead to strain and deformation after long-term use. The left and right elastic metal sheets are difficult to keep consistent and the repeated elastic lifting will lead to difficulty in ensuring the reliability of the contact and conduction, and there are certain safety hazards; moreover, the processing and assembly process of the elastic metal sheets is relatively complicated, using a lot of materials, and the yield is relatively low

[0003] The invention patent application with application number 201410499136.1 discloses an improved leakage protection socket, the moving metal sheet is elastically arranged in the lifting plate through the reset button and the lock hook After the buckle fits and pops up, the lifting plate is lifted to make the moving metal piece and the static contact end contact and conduct. Metal sheets, etc., have a complex structure and high processing costs; 3. The on-off method of lifting and closing needs to overcome the resistance of the reset spring on the reset button to close, which takes a relatively long time and is easy to cause spring strain; Block shape, no anti-extrusion structure, easy to escape from the locking piece mounting seat
