Operating mechanism of circuit breaker

Abstract

The invention relates to the field of low-voltage electric appliances, in particular to an operating mechanism of a circuit breaker. The operating mechanism comprises a handle, a connecting rod, a jump fastener, a lock fastener, a moving contact piece and an arc-shaped sliding groove which are arranged in a shell of the circuit breaker. The handle is arranged on the shell in a pivoted mode, one end of the handle protrudes out of the shell to be operated by a user, and the other end of the handle is rotationally connected with the front end of the connecting rod; the rear end of the connecting rod is inserted into a kidney-shaped connecting hole formed in the jump fastener and is in sliding fit with the sliding groove; the hasp end at one end of the jump fastener is in hasp fit with the hasp table of the lock fastener, and the other end of the jump fastener is rotatably connected with one end of the moving contact piece to form a jump buckle rotating center; the lock fastener is pivotally arranged on the shell; the moving contact piece is rotatably arranged on the second rotating shaft through a kidney-shaped hole formed in the middle of the moving contact piece; and the other end of the moving contact piece is provided with a moving contact matched with the static contact. The operating mechanism of the circuit breaker is simple in structure and easy to assemble, and the assembling space is saved.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an operating mechanism of a circuit breaker. Background technique [0002] The existing circuit breakers have complex structures and complex processes, making it difficult to realize automatic production. Moreover, the operating mechanism of the existing circuit breaker takes up a large space, which cannot meet the needs of the development trend of intelligent and miniaturized circuit breakers; once the circuit breaker needs to add product functions, such as detection modules, communication modules, etc. The volume increases. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide an operating mechanism for a circuit breaker, which has a simple structure, is easy to assemble, and saves assembly space. [0004] To achieve the above object, the present invention adopts the following technical...
