Abstract
본 발명은 얇은 금속판과 같은 가동자 도체(13b)로 구성된 가동자(13)에 필요한 기계적 강도가 충분히 높고, 가동자 도체(13b)에 용접되는 가동 접점(13a)의 접합 강도의 신뢰성이 높으며, 종래 가동자와 비교하여 제조 비용이 저렴한 가동자를 구비한 회로 차단기에 관한 것이다. 이 가동자(13)는 하기와 같이 설계된다. 금속판으로 제조된 가동자 도체(13b)의 일단부는 소정폭을 갖는 판형부(13e)에 형성되고, 이 가동 접점(13a)은 이 판형부(13e)에 설치되어 있다. 가동자 도체(13b)는 그 다른 단부가 케이싱(1)의 바닥(1c)과 수직하도록 중간부에서 90° 비틀려져 있다.According to the present invention, the mechanical strength required for the mover 13 composed of the mover conductor 13b such as a thin metal plate is sufficiently high, and the reliability of the bonding strength of the movable contact 13a welded to the mover conductor 13b is high. A circuit breaker having a mover having a lower manufacturing cost compared to a conventional mover. This mover 13 is designed as follows. One end of the movable conductor 13b made of a metal plate is formed in the plate portion 13e having a predetermined width, and the movable contact 13a is provided in the plate portion 13e. The mover conductor 13b is twisted 90 degrees at the middle so that its other end is perpendicular to the bottom 1c of the casing 1.
