Leakage protection socket with reverse wiring and end of life detection function

Abstract

The invention provides a leakage protection socket with reverse wiring and end of life detection functions, which can mechanically and compulsively trip when the leakage protection function is lost. The leakage protection socket comprises a first contact switch, a second contact switch and a tripper linked with a rest button, wherein the center of the double induction coil of a leakage current detection circuit is provided with an insulating post; the first contact switch and the second switch are both provided with a pair of static sheet metal with a stationary contact and a pair of movable sheet metal with a movable contact; a pair of movable sheet metal of the first contact switch is bent to extend into two guidance through holes of the center insulating post of the double induction coil; a pair of movable sheet metal of the second contact switch is fixed on the tripper; and a pair of movable sheet metal of the first contact switch and a pair of movable sheet metal of the second contact switch are electrically connected by a flexible wire. The utility model has the beneficial effects that the invention has reasonable connection mode of each sheet metal, and reliable contact touch, lightens the burden of the reset spring and has smooth action.

Description

technical field [0001] The invention relates to a leakage protection socket, in particular to a leakage protection socket with the functions of reverse wiring and end-of-life detection. Background technique [0002] The general leakage protection socket on the market does not have the function of preventing reverse wrong wiring. When the installer mistakenly connects the live wire and neutral wire of the wall to the power output terminal of the leakage protection socket, the output jack on the cover of the leakage protection socket will That is, there is power output, and there is no leakage protection circuit for the current flowing through the electrical equipment at this time. Therefore, the leakage protection socket does not play any leakage protection function at this time. If leakage occurs, it is very easy to cause electric shock accidents for users. In addition, the general-purpose leakage protection socket does not have the function of end-of-life detection. When th...

It includes a shell with an output jack, a conductive socket corresponding to the output jack, a power input terminal, a power output terminal, a reset / trip mechanism, a leakage current detection circuit, an electromagnetic tripping mechanism, an analog leakage current generating mechanism, and Power output indication circuit; reset / tripping mechanism includes a reset button, a reset start switch linked with the pressing action of the reset button, a set of first contact switches for conducting the power input and power output, a set of first contact switches for conducting the power input The second contact switch of the terminal and the conductive socket and the release linked with the reset button, etc., the problem of this leakage protection socket is: the first contact switch and the second contact switch have different dynamic and static metal sheet structures and connection methods. As reasonable as possible, the structure is complicated and not flexible enough; it does not have the function of forced tripping, and it may cause electric shock hazard after the reset / trip mechanism or detection electronic components are damaged in the reset state during operation
