Abstract

The invention discloses an opening and closing device of a circuit breaker, which comprises a housing, a static contact, a movable contact and a closing rod. The static contact is installed in the housing, and the movable contact is slidably installed in the housing. The closing rod is rotatably installed in the housing and extends out of the outer wall of the housing. The housing is rotatably equipped with a closing shaft. The outer wall of the closing shaft is fixed with a closing cam. The outer wall of the closing cam is equipped with a cam lever and a movable contact. The end of the cam rod is connected with the cam rod. When the closing cam rotates to the working position, the movable contact and the static contact can be disconnected or connected by the movement of the cam rod. The cooperation of the closing cam and the cam lever of the present invention controls the contact between the static contact and the movable contact, so that the micro circuit breaker can be closed and opened, and the closing cam is driven by the power component to rotate, so that the circuit breaker can be closed smoothly. Therefore, the problem that the operating handle is extremely prone to twisting in the existing circuit breaker can be avoided.

Description

technical field [0001] The invention relates to the field of circuit breaker opening and closing devices, in particular to a circuit breaker opening and closing device. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. When the side-operated circuit breaker is operated, because its force is a unilateral thrust, the operating handle is easily twisted and deformed, and its internal structure is easily broken after a long period of time. Contents of the invention [0003] In view of this, the object of the present invention is to propose an opening and closing device for a circuit breaker to solve all or one of the problems in the background technology. [0004] Based on the above purpose, the present invention provides an opening and closing device for a circuit breaker, which includes a...
