Description

회로 차단기Circuit breaker

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도-제3도는 본 발명의 일실시예를 나타낸 것이며,1 to 3 show an embodiment of the present invention,

제1도는 부분 종단면도.1 is a partial longitudinal cross-sectional view.

제2도 및 제3도는 각각 고정단자와 스페이서의 분리상태 사시도와 조합상태의 사시도.2 and 3 are a perspective view of a separated state and a combined state of the fixed terminal and the spacer, respectively.

Claims (1)

접점(26)이 부설되어 몰드 케이스(21)의 저부 내벽면과 일정간격을 띄워서 배설된 고정단자(22)와 선단에 부설된 접점(28)이 상기 고정단자(22)의 접점(26)과 접리되도록 회동가능하게 설비된 가동아암(24)과 이 가동아암(24)의 선단측에 상기 가동아암(24)의 대략 회동범위 전체에 걸쳐서 배설된 자성그리드판(30a)으로 된 소호장치(30)와 상기 고정단자(22)에 연결되고, 상기 소호장치(30)를 향하는 단부를 갖는 아크런너(32)를 구비하는 회로 차단기에 있어서 상기 고정단자(22)와 상기 몰드 케이스(21)의 저부 내벽면간의 간격을 규제하여 삽입설치되는 스페이서(23)와 일체물로서 형성된 상기 아크런너(32)를 설비한 것을 특징으로 하는 회로 차단기.The contact terminal 26 is disposed to be spaced apart from the inner wall surface of the bottom of the mold case 21 and the fixed terminal 22 and the contact 28 installed at the tip are connected with the contact 26 of the fixed terminal 22. A extinguishing device 30 comprising a movable arm 24 provided to be foldable and a magnetic grid plate 30a disposed on the front end side of the movable arm 24 over the entire rotation range of the movable arm 24. ) And a bottom of the fixed terminal 22 and the mold case 21 in a circuit breaker having an arc runner 32 connected to the fixed terminal 22 and having an end facing the arc extinguishing device 30. A circuit breaker, characterized in that the arc runner (32) formed as an integral part with a spacer (23) inserted and installed by restricting the interval between inner wall surfaces. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
