Abstract

가동 접촉자부 및 이를 포함하는 직류 릴레이가 개시된다. 본 발명의 실시 예에 따른 가동 접촉자부는 하부 요크를 포함한다. 하부 요크는 가동 접촉자와 고정 접촉자 사이에서 발생되는 전자기적 반발력을 상쇄하는 자기력을 형성한다. 하부 요크는 가동 접촉자를 지지하는 지지부 및 지지부와 연결되는 윙부를 포함한다. 윙부는 지지부보다 작은 두께를 갖게 형성된다. 일 실시 예에서, 윙부는 지지부보다 짧은 길이를 갖게 형성된다. 따라서, 하부 요크의 전체 무게가 감소되면서도, 하부 요크의 면적이 증가되고, 지지부의 두께 및 길이가 유지될 수 있다. 결과적으로, 하부 요크의 자기력의 세기, 작동 신뢰성, 진동 또는 충격에 대한 내구성이 향상될 수 있다.
