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: four active contacts are arranged on a power input metal sheet, a power output conductor and a power output metal sheet are provided with four static contacts together. The four pairs of active and static contacts form four pairs of power switches which are parallelly arranged. The leakage protection socket is further provided with a trip gear which can enable four pairs of active and static contacts to contact / break off. 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 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 user to change the leakage protection socket through displaying the life-span stop by a fault state indication lamp. 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 power socket with leakage protection function, in particular to a leakage protection socket that can automatically perform end-of-life detection on the power socket without operating any components and display the detection result; in addition, the leakage protection socket can also be mechanically The structure is forcibly tripped to cut off the power output of the socket. Background technique [0002] With the continuous development of the leakage protection socket (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, its internal components fail and the leakage protection function is lost, the user can be reminded in time to replace the new product. [0003] However, the common leakage protection sockets currently on the market basically do not have the end-of-life detection funct...

AI Technical Summary

Problems solved by technology

[0003] However, the common leakage protection sockets currently on the market basically do not have the end-of-life detection function. Users cannot detect whether the leakage protection socket has expired before using it. Therefore, it often happens that the leakage protection socket has expired, but The user is still unaware, continues to use, presses the reset button, the reset button can still be reset, the load output terminal of the leakage protection socket and the single-phase three-wire power output jack on the surface of the socket still have power output, misleading the user to continue to use

When leakage occurs, since the leakage protection socket has expired, it can no longer play any protective role, so it is very easy to cause the user to be electrocuted and killed.
