Title: 동축 릴레이
IPC: H01H50/10
Filed: 2000-04-21
Abstract: 동축 릴레이는 접촉 블록과 전자석 블록으로 이루어진다. 접촉 블록은 각각이 코어 도체와 그 코어 도체를 둘러 싸고 있는 차폐 도체로 구성된 복수의 동축 커넥터을 보유하고 있다. 코어 도체는 각각의 동축 접촉부를 한정하기 위해 차폐실 안쪽으로 연장 된다. 적어도 하나의 가동 철편은 두 인접 동축 접촉부를 개패(開閉)하기 위한 차폐실내의 배치되어 있다. 가동 철편에는 접촉 블록의 상부면 위로 돌출하고 동축 접촉부접촉부향시키는 방향으로 가동 철편에 가압하기 위한 접촉 블록에 고정된 복귀 스프링과 맞물린 절연 액추에이터가 재공된다. 전자석 블록은 적어도 하나의 전자석과 하나의 접극자를 보유하고 있으며, 접극자는 전자석 블록이 접촉 블록에 결합될 경우 액추에이터와 연결될 수 있다. 접극자는 동축 접촉을 개방하는 제 1위치로 부터 그 동축 접촉을 폐쇠하는 제 2위치 까지 피벗 축을 중심으로 움직인다. 전자석은 전자석과 접촉 블록에 고정된 아래 단을 갖고있는 비-자성 도체의 프레임을 포함한다. 프레임은 접극자를 피벗 방식으로 지지 하는 리테인너 메카니즘(Retainer Mechanism)을 구비한다. 따라서, 전자석과 접극자 사이의 자석 갭의 거리을 고정할수 있으며, 전자석 블록을 접촉 블록에 결합하는 시간을 변화시키지 않게 되어, 릴레이는 상기 전자석의 여기에 응답하여 신뢰성 있는 접극자의 움직임을 가질수 있다.
