Description
본 고안은 회로차단기의 가동접촉자에 관한 것으로, 특히 가동접촉자의 하부에 삽입된 스프링을 삭제하고, 차단시 신속한 차단에 도움을 주기 위하여 스프링 대신에 가동자의 형상을 U 자형으로 만들어 U 자의 탄성이 스프링의 역할을 대신하도록 함으로써, 조립성을 향상시키도록 한 회로차단기의 가동접촉자에 관한 것이다.The present invention relates to a movable contactor of a circuit breaker. In particular, the spring inserted in the lower portion of the movable contactor is deleted, and the shape of the mover is U-shaped instead of the spring to assist in quick disconnection in case of breaking. It relates to a movable contactor of a circuit breaker to improve the assemblability by replacing the role of.
본 고안은 소형 누전 혹은 배선용 차단기에 적용되는 기술로서, 차단기는 누전이나 과전류에 의한 감전이나, 화재를 예방하는데 그 사용목적이 있다. 누전이나, 과전류 발생시 누전 검출부 혹은 과전류 감지장치에서 감지된 이상신호를 기구부를 통하여 차단시켜 주는 가동접촉자에 적용되는 기술로서 보다 신속한 차단을 위하여 고안된 기술이다.The present invention is a technology applied to a small leakage circuit or a circuit breaker, and the circuit breaker has a purpose of preventing electric shock or fire caused by an electrical leakage or an overcurrent. It is a technology that is applied to a movable contactor that cuts off an abnormal signal detected by an earth leakage detector or an overcurrent detection device through a mechanism part when a short circuit or an overcurrent occurs.
종래의 기술에 의한 회로차단기에는 제1도 및 제2도에 도시한 바와 같이, 차단부가 가동접촉자(1)와 고정접촉자(2) 그리고, 가동접촉자의 아래부분에 연결된 스프링(3)으로 구성되며, 크로스바(5)가 가동접촉자(1)의 위에 연결되어 있다. 가동접촉자의 일측단에는 리드와이어(4)가 설치되어 부하측과 연결된다.In the circuit breaker according to the prior art, as shown in FIGS. 1 and 2, the breaker comprises a movable contactor 1, a fixed contactor 2, and a spring 3 connected to a lower portion of the movable contactor. The crossbar 5 is connected on the movable contact 1. One end of the movable contact is provided with a lead wire 4 is connected to the load side.
이와 같이 구성된 회로차단기는 누전이나 과전류 발생시 검출부에서 받은 신호에 의하여 크로스바(5)가 상하운동을 하면서 투입과 차단이 이루어 졌다. 크로스바가 아래 방향으로 이동시 가동접촉자(1)가 같이 움직이면서 고정접촉자(2)와 접촉이 되며, 크로스바(5)가 윗방향으로 움직이면 가동접촉자의 아래부분에 있는 스프링(3)의 복원력에 의하여 가동접촉자(1)를 윗방향으로 밀어줌으로써 고정접촉자(2)와 이격되어 차단이 되는 원리이다.The circuit breaker configured as described above was closed and closed while the crossbar 5 moved up and down by a signal received from the detection unit when a short circuit or an overcurrent occurred. When the crossbar moves downward, the movable contactor 1 moves together to come into contact with the fixed contactor 2. When the crossbar 5 moves upward, the movable contactor is moved by the restoring force of the spring 3 located below the movable contactor. By pushing (1) upwards, it is a principle of being blocked from being spaced apart from the fixed contact (2).
