Leakage current protection device for power plug

A leakage current protection plug comprising:

• a body formed by a top cover and a base;
• a moving assembly disposed in the body, which includes a control circuit board and a detector assembly and a trip assembly disposed on the control circuit board;
• two input insertion plates and two output moving contact arms assembled with the moving assembly;
• and
• output conductor wires,
• wherein each output moving contact arm is formed integrally and fixed to the detector assembly,
• wherein the detector assembly includes a detector coil box, and a detector coil and at least one metal plate disposed inside the detector coil box, and a detector coil cover which covers and fixes the detector coil and the metal plate, wherein the detector coil box defines a through hole for allowing the output moving contact arms to pass through, and wherein the output ends of the output moving contact arms pass through the through hole and are directly connected to the respective output conductor wires.
