Abstract
A terminal box, including at least a box (51) having a receiving part (10), a movable control rod (7), multiple electric contacts (8), a thermostat (9) having a terminal (91), and a wiring mechanism (12). The movable control rod (7) is disposed on the box (51) and partially extends therefrom. The electric contacts (8) are disposed in the box (51). The thermostat (9) is disposed on end surface of the box (51). The receiving part (10) operates to receive the thermostat (9). One end of the electric contact (8) extends from the box (51) and forms a connecting part (81). A separating plate (11) is disposed between the connecting part (81) and the thermostat (9). One end of the wiring mechanism (12) is connected to the connecting part (81), and the other end thereof bypasses the outside of the separating plate (11) and is connected to the terminal (91). If the thermostat experiences temperature detection failure, users of the motor can easily remove the wiring mechanism, and timely switch off the power supply connected to the motor via an external protection circuit thereby preventing the motor from being burned out.
