Abstract

The invention aims to solve problems existing in the prior art, and discloses a tripping mechanism component. The tripping mechanism component comprises a shell, wherein a lock catch mechanism and an electromagnetic system are arranged on the shell; the lock catch mechanism comprises a tripping cam and a reset button; a jump fastener and a reset spring are arranged on the reset button; the tripping cam comprises a lock catch part at the upper part, a rotating part at the middle part and a cam part at the lower part; the tripping cam is connected onto the shell in a rotating manner through the rotating part; the tripping cam is connected with the jump fastener through the lock catch part; a brake spring for preventing the tripping cam from rotating is arranged on the tripping cam; and a push rod for pushing the cam part is arranged on the electromagnetic system. The tripping mechanism component has the beneficial effects that a tripping function is realized by using a simple structure, and the structure is simpler and stabler compared with the structure in the prior art.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a tripping mechanism assembly. Background technique [0002] The tripping mechanism of a leakage circuit breaker with the publication number of 104701108A includes a connecting rod, a pull rod, a tripping coil for inducing leakage current, and a tripping piece. One end of the pulling rod is arranged inside the tripping coil, and the other end is Connected with the tripping piece, the tripping piece is provided with a through hole, one end of the connecting rod is connected with the current main circuit, and the other end is provided with a bending portion, and the bending portion is arranged in the through hole. In the tripping mechanism of the leakage circuit breaker disclosed in the present invention, when the circuit generates a sufficiently large leakage current, the tripping coil is energized, and due to the effect of electromagnetic induction, the ...
