Kind Code:
A1
Abstract:
The present invention provides a circuit breaker, comprising a housing, a contact support member, a counterforce elastic member, a movable contact, a static contact, a lock fastener, a handle, a connecting rod, and a tripper. The contact support member comprises a body portion, a drive portion, and an elastic energy storage portion; the body portion is rotatably connected to the housing by means of a fulcrum rotation shaft; the drive portion and the elastic energy storage portion are respectively located at both sides of the fulcrum rotation shaft; the drive portion is connected to the handle by means of the connecting rod. The movable contact is connected to the elastic energy storage portion; during overrun rotation of the handle, the movable contact abuts against the static contact, and the body portion moves relative to the movable contact; a displacement difference is generated between two ends of the elastic energy storage portion, and the two ends are bent to generate a rebound force directing to the static contact, so as to press the movable contact against the static contact.
