Embodiment Construction

[0033] Such as figure 1 As shown, the novel leakage protection socket disclosed by the present invention is mainly composed of a housing and a control circuit board 18 installed in the housing to realize whether the leakage protection socket has power output or not.

[0034] The housing is composed of an upper cover 2, an insulating middle bracket 3 and a base 4; a metal grounding mounting plate 1 is provided between the upper cover 2 and the insulating middle bracket 3; between the insulating middle bracket 3 and the base 4 A control circuit board 18 is provided therebetween.

[0035] Such as figure 1 , figure 2 As shown, there are power output jacks 5, 6, a reset button hole 8-A, a test button hole 7-A and a status indicator hole 30-A on the upper cover 2. A reset button (RESET) 8 and a test button (TEST) 7 are arranged 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...

Abstract

The invention discloses a novel electric leakage protection socket, which is characterized in that: input ends of a live wire and a zero line of a power supply are respectively extended with a right-angled triangular point discharge metal sheet used for discharge; and points of the two metal sheets are oppositely arranged and spaced at a certain interval. In a concrete embodiment of the invention,power input connection pieces connected with input metal sheets of the live wire and the zero line of the power supply and input terminal screws of the live wire and the zero line of the power supplyare respectively extended with a point discharge metal sheet for discharge, and points of the two metal sheets are oppositely arranged and spaced at a certain interval. The live wire of the power input end of the electric leakage protection socket is also connected with the zero line at the power input end through a tripping coil and a voltage dependent resistor. The novel electric leakage protection socket can prevent thunder and lightening and the damage caused by high transient voltage due to other causes, and also prevent loads connected with the electric leakage protection socket, namelyhousehold appliances such as refrigerators, color TVs, air conditioners and the like from being stricken by high voltage.

Description

technical field [0001] The invention relates to a novel electric leakage protection socket, in particular to a novel electric leakage protection socket with the lightning protection function. 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 be reset, and the load of the earth leakage protection socket The single-phase three-wire power output jack on the surf...
