Abstract
A circuit breaker with the locking device, wherein the locking device comprises an executing lever (1) and a pressing plate (2), wherein a hole shaft of the executing lever (1) is rotatably mounted in a base (3) of a circuit breaker. An elastic piece (111) is arranged between one end of the executing lever (1) and the base (3), and the other end of the executing lever (1) is provided with a locking end which can be connected with a locking portion (210) at one side of the pressing plate (2) in a locking manner. The pressing plate (2) is mounted in the base (3) and can rotatably oscillate relative to the base (3). The locking portion (210) at one side of the pressing plate (2) comprises an unlocking surface (211) and a locking surface (212) which correspond to the locking end (120) respectively and are adjacent to each other, and a sliding step (213) is arranged between the unlocking surface (211) and the locking surface (212). A contact portion (220) which is in contact connection with a circuit breaker operating mechanism is arranged at the other side of the pressing plate (2). A magnetic actuator (5) which can drive the pressing plate (2) to oscillate is also arranged above the pressing plate (2) correspondingly. The circuit breaker with the locking device provided by the invention is firm in locking structure, stable in action process and simple in mechanical structure.
