Abstract

The invention discloses a clutch mechanism and a circuit breaker, and relates to the technical field of circuit breakers. The clutch mechanism is used for being connected with an operating mechanism and comprises a driving assembly, a connecting rod and a rotating shaft, wherein the rotating shaft is used for being connected with the operating mechanism and provided with a kidney-shaped groove, the driving end of the connecting rod extends into the kidney-shaped groove, the driving assembly drives the driving end of the connecting rod to slide in the kidney-shaped groove to enable the rotatingshaft to rotate in the first direction so as to switch on the operating mechanism, and the driving assembly drives the rotating shaft to rotate along the second direction so as to switch off the operating mechanism. According to the clutch mechanism, through mutual cooperation of the driving assembly, the connecting rod and the rotating shaft, automatic switching-on and switching-off of the operating mechanism can be achieved in the power-on state, and manual switching-on and switching-off of the operating mechanism can be achieved by manually controlling the connecting rod in the power-off state, so that safety and reliability are achieved.

Description

technical field [0001] The present invention relates to the technical field of circuit breakers, in particular to a clutch mechanism and a circuit breaker. 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. Circuit breakers can effectively improve the safety of electrical equipment and are classified according to installation methods, including plug-in type, fixed type and drawer type. With the miniaturization of electrical equipment, the overall structure and operation mode of the matching circuit breaker also needs to be gradually upgraded. Among them, the plug-in circuit breaker is widely used in communication because of its compact structure, space saving and convenient installation. With the development of Internet of Things technology, plug-in circuit breakers are required to have r...
