Abstract
The utility model provides an electric leakage protection power plug with an improved circuit. The electric leakage protection power plug comprises a housing, an insert pin, a test device, a reset device and a controller, wherein the test device and the reset device are connected with the controller, and the controller comprises a circuit board, residual current detection special integrated circuits IC1 and IC2, a ground wire voltage detection comparator IC3 and a trip driving protection circuit. The electric leakage protection power plug is characterized in that the residual current detection special integrated circuits IC1 and IC2 and the ground wire voltage detection comparator IC3 are integrated into a whole, the residual current detection special integrated circuits IC1 and IC2 and the ground wire voltage detection comparator IC3 are packed by the housing, and a plug on the housing is in inserted connection with a jack in the circuit board are and is communicated with a circuit. After the structure is adopted, the residual current detection special integrated circuits IC1 and IC2 and the ground wire voltage detection comparator IC3 are integrated into a whole and are detachably connected with the circuit board, and welding points are reduced, so that parts can be preferably protected, and the service life of the electric leakage protection power plug can be prolonged.
