Abstract
A tripping mechanism for a circuit breaker comprises a connecting rod assembly and a control assembly, wherein one end of the connecting rod assembly is connected with a rotating shaft assembly for driving the circuit breaker to be switched off in a driving manner, and the other end of the connecting rod assembly is provided with a jump pin which can be connected with the control assembly in a latching manner, and the jump pin is also provided with a U-shaped groove. The control assembly comprises a switching-off latch which is rotatably mounted. The end part of the switching-off latch can be connected with the U-shaped groove in a latching and limiting manner, and the circuit breaker triggers the end part of the switching-off latch to be tripped from the U-shaped groove when being switched off, and therefore the rotating shaft assembly connected with the connecting rod assembly drives the circuit breaker to be switched off. The tripping mechanism for the circuit breaker, which is provided by the present invention, is stable in latching, simple in structure and accurate in action.
