The invention discloses an electric closing mechanism of a miniature circuit breaker. The electric closing mechanism comprises a shell, a control circuit board, a transmission mechanism, a tripping separation mechanism and a drive motor, wherein the shell comprises a base and a cover; the transmission mechanism comprises a worm wheel, a worm and a transmission gear set; and the tripping separation mechanism comprises an incomplete gear drive wheel and a deflecting cam. A drive handle is rotated in the meshing process by ingeniously using an incomplete gear on a drive wheel and an incomplete gear on the drive handle; a drive handle square shaft and a drive handle and a rail shaft arranged in the drive handle simultaneously act on a circuit breaker handle to complete closing operation on the circuit breaker. Meanwhile, a cam groove is arranged in the incomplete gear drive wheel and the deflecting cam is arranged in the cam groove, so that the deflecting cam can be switched between an upper stop position and a lower stop position due to the rotation position of the incomplete gear drive wheel.
Description
technical field [0001] The invention relates to the technical field of small circuit breakers, in particular to an electric closing mechanism of a small circuit breaker. Background technique [0002] At present, electric closing mechanisms are widely used in prepaid meter miniature circuit breakers and photovoltaic power generation circuit breakers. The electric closing mechanism is spliced together with miniature circuit breakers as a driving mechanism for automatic closing and automatic opening of miniature circuit breakers. [0003] The driving mode of the electric closing mechanism in the prior art is to use the drive handle square shaft or triangular shaft to drive the circuit breaker to perform closing and opening operations. Since the drive shaft is made of metal, the handle of the circuit breaker is made of plastic. In the process of driving, it must bear a large torque, and the hardness of the material between the two is very different. Therefore, after repeated o...
