The invention discloses a power supply connector with electric leakage tripping, surge protection and self fault detection functions. The power supply connector comprises a circuit board, a magnetic ring and an electromagnetic coil which are electrically connected with the circuit board respectively; the upper end of a hook is fixed on a reset button, the lower end extends into a lifter; a first spring is arranged between a middle frame and the reset button; a second spring is arranged between the middle frame and the lifter, a third spring is arranged on the lower side of the lifter, an ironcore is arranged in the electromagnetic coil, the right end of the iron core is connected with a fourth spring, the left end of the iron core is connected with a lock pin, the lock pin extends into the lifter, a window is formed in the lock pin, and a microswitch is arranged on the lower side of the lifter and electrically connected with the circuit board. The power supply connector is used for the connection between a power supply and an electric device, when electric leakage occurs in a load circuit and the current difference exceeds 6mA, the power supply connector is triggered to generate tripping action, the connection between an input end contact and a load end contact is disconnected, the power supply is cut off, and the personal safety of a user is guaranteed.
Description
technical field [0001] The invention relates to the technical field of power connectors, in particular to a power connector with leakage tripping, surge protection and self-fault detection. Background technique [0002] The electrical device needs to be plugged into the power supply and powered on. There is no leakage protection device between the existing electrical device and the power source. If the electrical device leaks due to aging and other reasons during use, it will easily bring users Personal injury, electric shock hazard. Contents of the invention [0003] The invention provides a power connector with leakage tripping, surge protection and self-fault detection. [0004] The purpose of the present invention is to solve the problem that current leakage occurs during the use of existing electrical devices due to aging and other reasons, which may easily cause personal injury to users. [0005] The technical solution adopted by the present invention to solve the ...
