Creepage protecting socket with life end checking function

Abstract

The present invention discloses an electric leakage protection socket which automatically carries out life-span termination detection and displays detection results. The present invention is characterized in that: a pair of elastically connected output metal sheets in connection with an output end of a power source is arranged on a socket circuit board; a pair of moving contacts is arranged on the metal sheets; two pairs of fixed contacts are arranged on a power output conductor; two pairs of fixed contacts on the power output conductor are vertically corresponding to the moving contact on a power input metal sheet and the moving contact on the elastically connected output metal sheets respectively, forming two groups and four pairs of switches. A life-span termination detection circuit is also arranged on the circuit board. When the socket is switched into the power source, the detection on electric leakage protection function can be automatically carried out; if the life-span termination of the socket is discovered, a reset button is prevented from resetting, ensuring that both a loading end of the socket and a power output hole have no power output, and users are reminded to replace the electric leakage protection socket in time through a reset indicator light. The present invention is full in functions, good in safety and capable of guaranteeing the personal safety of users as well as electric appliance safety indeed.

Description

technical field [0001] The invention relates to a leakage protection socket, especially a leakage protection socket that can automatically detect the end of life of the leakage protection socket and display the detection result without operating any parts after the power input end of the leakage protection socket is connected to the power line in the wall At the same time, the leakage protection socket can also be forcibly tripped through the mechanical structure to cut off the power output of the leakage protection 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, 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. ...

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.
