Claims

[Claims for Utility Model Registration] A charge cam that is rotationally driven, a charge arm that engages with the charge cam and is rotationally displaced, a closing spring that is charged by the rotation of the charge arm, and a contact opening/closing mechanism. and a closing toggle link mechanism, which rotates the charging cam to charge the closing spring, and then closes and opens the contact opening/closing mechanism with the stored force by giving a command. In the circuit breaker, first and second pins provided on the charging cam, and a first pin that engages with the first and second pins, respectively, are provided.
, a cam stopper having a second engaging portion and provided to reciprocate within a certain angle, and a return spring biasing the cam stopper to one stop position of the reciprocating movement; When the charging cam is rotated when closing with stored force, the first pin collides with the first engaging portion and rotates the cam stopper against the return spring, and the cam stopper is closed. Due to the rotation of the second engaging portion, the second engaging portion
A circuit breaker characterized in that the charging cam is stopped by colliding with the pin of the circuit breaker.
