Leakage protection socket

Abstract

A protection socket of electric leakage is prepared as adding a pair of elastic metal plates connected with power supply output end on socket circuit board, setting a pair of active contactors on said metal plates and two pairs of static contactors on power supply output conductor, setting two pairs of static contactors on power supply output conductor to correspond separately to active contactors on power supply input metal and elastic metal sheets for forming two sets of four pairs of switches and adding life-end detection circuit on said circuit board for reminding user timely to replace said protection socket when service life time of said protection socket is ended.

Description

technical field [0001] The invention relates to a power socket with leakage protection function, in particular to a leakage protection socket which can automatically detect the end of life of the leakage protection socket and display the detection result without operating any parts. In addition, the leakage protection socket can also be forcibly tripped through the mechanical structure to cut off the power output of the socket. Background technique [0002] With the continuous development of the leakage protection socket (referred to as GFCI) industry, people have higher and higher requirements for the safety of the leakage protection socket. It is hoped that during the use of the leakage protection socket, when its life ends, that is, its internal components fail, and when the leakage protection function is lost, the user can be reminded in time to replace it with a new product. However, the current leakage protection sockets that are common in the market do not have the e...

Problems solved by technology

However, the common leakage protection sockets on the market do not have the end-of-life detection function. Users cannot detect whether the leakage protection socket has expired before using it. Therefore, when the leakage protection socket has expired, the user still does not know , continue to use, press the reset button, the reset button can still be reset, the load output terminal of the leakage protection socket and the single-phase three-wire power output jack on the surface of the socket still have power output, misleading users to continue to use

When there is a leakage phenomenon, since the leakage protection socket has no protective effect, it is very easy to cause the user to be electrocuted and die.
