Creepage protecting socket

Abstract

This invention discloses a leakage protection socket with functions of testing the end of life automatically and displaying the test result characterizing in adding a pair of elastic metal plates connected with the output of a supply on the CB of a socket, in which, a pair of moving contactors is set on the metal plates and two pairs of static contactors are set on the output conductor of the supply and correspond to the moving contactors on the input metal plates of the supply and the elastic metal plates to constitute two sets of four pairs of switches, further more, a test circuit for end of life is added on the CB to test the leakage protection automatically and holds back reset of a reset button if it finds out the life of the socket is end when a socket is plugged to the supply and stops the load end of the socket and the output hole of the supply outputting power and reminds users to exchange the socket by a reset indication lamp.

Description

technical field [0001] The invention relates to a leakage protection socket, 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. button to cut off the output of the power supply. 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, when its internal components fail and lose the leakage protection function, the user can be reminded in time to replace it with a new product. [0003] However, the common earth leakage protection sockets on the market not only do not have the end-of-life detection function, but also do not have any reminder function for the user when their life ends, and th...

Problems solved by technology

[0003] However, the common earth leakage protection sockets on the market not only do not have the end-of-life detection function, but also do not have any reminder function for the user when their life ends, and the reset button can still be reset, and the load of the earth leakage protection socket The single-phase three-wire power output jack on the surface of the output terminal and the socket still has power output, misleading users to continue to use

When there is a leakage phenomenon, the leakage protection socket can not play any protective role, and it is very easy to cause the user to be electrocuted and die.
