Creepage protecting socket

Abstract

The present invention discloses a leakage protection socket with automatic life-span stop detection and detection result displaying functions, which is characterized in that: a pair of elastic metal sheets are arranged on the socket circuit board and connected with the output of the power source and a pair of active contacts is arranged on the metal sheets. Two pairs of static contacts are arranged on a power output conductor. Two pairs of static contacts on the power output conductor are corresponding to the active contact on the power input metal sheet and the active contact of the elastic metal sheet, thereby forming four pairs in two groups of matching switches. A life-span stop detection circuit is further arranged on the circuit board to detect the leakage protection function automatically when the socket is inserted into the power source, and then stop the reset of a resetting button if finding out that the life-span of the socket is stopped so that the load end and the power output hole of the socket have no power output and remind user to change the leakage protection socket by a reset indication light. The present invention is of full functions and good safety and can indeed guarantee human body safety and appliance safety for users.

Description

technical field [0001] The invention relates to a leakage protection socket, especially 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 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. [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...

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.
