Abstract

The present disclosure provides an improved leakage protection socket with reverse connection protection function. The electromagnetic tripping mechanism comprises a trip coil, an iron core and a permanent magnet that fit with a return spring, the iron core has, in its front end, a boss to pull the lock for horizontal movement, the movable input contacts are clamped by a rib slot of an upper tripper that can moves upward and downward along with the reset button. There is also provided a reverse connection trip device, which has a slope that coordinates with the boss of the iron core, upon reverse connection, the trip coil generates a magnetic field in the same orientation with the permanent magnet.

Description

technical field [0001] The invention relates to a leakage protection socket, in particular to an improved leakage protection socket with reverse wiring protection function. Background technique [0002] The existing leakage protection socket generally includes a housing, a pair of output conductors with conductive sockets, a reset button, a power input terminal, a power output terminal, a pair of input movable contacts connected to the power input terminal, and a power supply output terminal. A pair of output moving contacts connected to each other, double induction coils and circuit boards for detecting leakage currents, and a lock for positioning the reset button hook to make the input moving contacts and output conductors conduct An electromagnetic tripping mechanism that separates the reset button from the lock when there is a leakage current, for example, the invention patent application with application number 201110048951.2. The electromagnetic tripping mechanism incl...
