Problems solved by technology

[0004] 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.

Embodiment Construction

[0038] like figure 1 As shown, the novel leakage protection socket disclosed in the present invention is mainly composed of a casing and a control circuit board 18 installed in the casing to realize the leakage protection socket with or without power output.

[0039] The casing is composed of an upper cover 2, an insulating middle support 3 and a base 4; a metal grounding mounting plate 1 is installed between the upper cover 2 and the insulating middle support 3; between the insulating middle support 3 and the base 4 A control circuit board 18 is mounted therebetween.

[0040] like figure 1 , figure 2 As shown, the upper cover 2 is provided with power output jacks 5 and 6, a reset button hole 8-A, a test button hole 7-A and a status indicator hole 30-A. A reset button (RESET) 8 and a test button (TEST) 7 are installed in the reset button hole 8-A and the test button hole 7-A, and the reset button 8 and the test button 7 pass through the metal grounding mounting plate 1 and...

Abstract

The invention discloses a novel earth leakage protection socket which is characterized in that the output terminals of a live conductor and a zero conductor of a power source are respectively providedwith two static contacts; two springs are sleeved on a reset guide pole, wherein one spring is a reset spring, and the other spring is a fast trip spring; and an analog leakage current generating switch and a reset start switch are arranged below a release. The invention has the advantages of long service life and stable, reliable and safe operation and has the functions of automatically detecting end of life and preventing lighting strike.

Description

technical field [0001] The invention relates to a leakage protection socket, in particular to a novel leakage protection socket with long service life, stable operation, reliability, good safety and anti-lightning function. [0002] The leakage protection socket disclosed in the present invention can automatically perform the end-of-life detection on the leakage protection socket and display the detection result without operating any components after its power input end is connected with the power line in the wall. Background technique [0003] With the continuous development of the leakage protection socket industry, people have higher and higher requirements for the safety and service life of leakage protection sockets. 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 the new product. At the same time, people...
