Abstract
The utility model relates to a novel circuit breaker tripping device, comprising a cover and a base which are vertically buckled with each other, wherein the base is internally provided with a tripper and a rotating mechanism, the tripper comprises a movable iron core, a coil sleeved on the iron core and an iron yoke sleeved outside the coil, the rotating mechanism comprises a buckle hinged on a shaft, the buckle is connected to a narrow part at the outer end of the movable iron core, and an outer contact of the buckle stretches out of a rectangular hole in the base and is matched with a breaking contact piece in a circuit breaker. The novel circuit breaker tripping device provided by the utility model is very convenient for mass production and debugging, and debugging can be carried out conveniently without assembling the circuit breaker in production. When remote control breaking or automatic signal control breaking is required to be carried out after the circuit breaker is assembled, the coil is electrified through a connector at the outer side of the base, the coil and the iron yoke sleeved outside the coil generate an electromagnetic force to attract the movable iron core, the movable iron core drives the buckle to rotate around the shaft, and the outer contact of the buckle is contacted with the breaking contact piece in the circuit breaker, thereby accomplishing remote control breaking or automatic signal control breaking.
