Example Embodiment

[0054] As shown in FIG. 1 , the leakage protection socket disclosed in the present invention is mainly composed of a casing and a circuit board 18 installed in the casing to realize the leakage protection socket with or without power output.

[0055] The casing is composed of an upper cover 2, an insulating middle layer bracket 3 and a base 4; a metal grounding mounting plate 1 is arranged between the upper cover 2 and the insulating middle layer bracket 3; There is a circuit board 18 .

[0056] 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 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 and the insulating intermediate support 3 Contacts components on circuit board 18 . Four snap ...

Abstract

The invention discloses a leakage protection socket for automatically detecting life termination and displaying detecting result, which is characterized in that a pair of elastic metal sheets connected with a power supply output terminal are added on a socket circuit board; the metal sheets are provided with a pair of moving contacts; a power supply conductor is provided with two pairs of static contacts; the two pairs of static contacts on the power supply output conductor respectively correspond to a moving contact on a power supply input metal sheet and a moving contact on the elastic metal sheets so as to form two groups of and four pairs of switches. A circuit for detecting the life termination is added on the circuit board. When the socket is connected with the power supply, the detection function for leakage protection can be automatically operated. If the termination of socket life is found, a reset button is prevented from resetting so that no power supply can be output from a loading terminal of the socket or from an output hole of the power supply. The invention has complete function and good safety and can ensure personal safety of users and electrical apparatus safety indeed.

Description

technical field [0001] The invention relates to a leakage protection socket, in particular to a safety device that can automatically perform life-end detection on the leakage protection socket and display the detection results without operating any components after the power input end of the leakage protection socket is connected with 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 use 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.
