Abstract

The utility model discloses a voltage overload protector possessing an automatic recovery function. The protector comprises a box body, a binding post arranged in the box body and a power supply lead connected to the binding post. The box body comprises a PCB board, an electromagnetic coil, a separation plate and an insulation shell. The PCB board is connected with the electromagnetic coil. The power supply lead is formed by an anode lead and a cathode lead. The anode lead is connected in series with a normally-closed switch and a manual switch. According to a technical scheme of the utility model, when an overvoltage detector detects that an external electric appliance is overload, the electromagnetic coil is energized and disconnects the normally-closed switch, and the power supply lead is broken. Through a timer and counter time delay, the electromagnetic coil is outage and closes the normally-closed switch so that the external electric appliance can be used again. The manual switch can be used to connect and disconnect the circuit at any time so that the voltage overload is prevented and the circuit can be automatically recovered. The structure is simple and operation is safe.
