Abstract:
1. A circuit breaker, comprising a box body, the box body comprising an upper cover, a bottom box, a travel switch, and a circuit breaker actuating mechanism, a wire inlet end, and a wire outlet end being arranged in the box body; wherein: an automatic closing function part is arranged inside the box body and comprises an automatic closing mechanical unit and an automatic closing control unit; the automatic closing mechanical unit comprises a motor and an intermediate transmission mechanism; the motor is adapted to rotate in a first direction or a second direction; the first direction is opposite to the second direction; the intermediate transmission mechanism is adapted to transform a rotating action of the motor into a reciprocating action of the circuit breaker actuating mechanism between a first position and a second position; the circuit breaker actuating mechanism is adapted to connect the wire inlet end to the wire outlet end when the circuit breaker actuating mechanism is in the first position; the circuit breaker actuating mechanism is adapted to disconnect the wire inlet end from the wire outlet end when the circuit breaker actuating mechanism moves away from the first position and towards the second position; the travel switch is adapted to contact the circuit breaker actuating mechanism and stop the rotation of the motor when the circuit breaker actuating mechanism is in the first position; and the travel switch is adapted to reverse a direction of the rotation of the motor when the circuit breaker actuating mechanism moves away from the first position and towards the second position.
