Abstract
Description
Claims (2)
- 과전류 및 단락전류 발생시 회동하여 고정접촉자로부터 이격되는 가동접촉자(2)와, 상기 가동접촉자가 회동가능하게 설치되는 메인 샤프트(3)를 구비한 배선용 차단기에 있어서;상기 메인 샤프트 양측면을 연결하는 메인 샤프트의 중앙면과 전로의 개로시 상기 메인 샤프트의 중앙면에 부딪히게 되는 가동접촉자의 접점 부착면 사이에 차단기의 온·오프 동작시 상기 가동접촉자가 메인 샤프트에 부딪힐 때의 충격을 완화시키기 위한 압축 코일스프링(4)을 설치하여서 된 것을 특징으로 하는 배선용 차단기.
- 제 1 항에 있어서,상기 압축 코일스프링은 메인 샤프트의 중앙면에 형성된 돌기(6)와 상기 돌기와 대응하도록 가동접촉자의 접점 부착면 상에 형성된 돌기(7)사이에 결합된 것을 특징으로 하는 배선용 차단기.
