Leakage protection socket

Abstract

The invention discloses a novel leakage protection socket, which is characterized in that: when a reset button is pressed down, the reset button and a test button are linked; an elastic sheet metal is arranged below the test button, and a test resistor is arranged below the elastic sheet metal; one end of the elastic sheet metal is positioned below the test button, while the other end is connected with a power live wire or a power zero line passing through a differential transformer; one end of the test resistor is positioned below the elastic sheet metal in a hanging way, while the other endis connected with the power zero line of a power input end; when the reset button is in a released state and a reset state, the test resistor and the elastic sheet metal are not contacted; and when the reset button is pressed down, the test resistor and the elastic sheet metal are contacted. When the power input end of the leakage protection socket is connected with a power cord in a wall, the test button is linked when the reset button is pressed, and the test button automatically detects timely whether the leakage protection socket still has a leakage protection function or not and displaysa detection result.

Description

technical field [0001] The invention relates to a novel earth leakage protection socket which can automatically detect whether the service life of the earth leakage protection socket is terminated by pressing the reset button in conjunction with a test button at the first time and display the detection result. Background technique [0002] With the continuous development of the leakage protection socket 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 the reset button can still ...

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, which misleads the user to continue using it, and the safety and reliability are poor.

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.
