Abstract
Description
Claims (1)
- 접속단자(3)(3')와 접지봉(4)이 몸체(2) 저면으로 접속되어 연결편(5) 사이에 위치되는 어레스터(6)에 이상전기 발생으로 방열될대 접지편(7)을 통해 접지봉(4)으로 접지토록 유도케 된 통상의 플러그(1)를 구성함에 있어서, 연결편(5)의 중간부로 절결부(5a)에 끼워진 금속피막저항(8)의 일측 단자핀(8a)을 통해 연결된 전기가 타측 단자핀(8b)에 저온납(9)으로 융착된 탄동스프링(10)이 중공형의 접속단자(3')내부로 접속되어 이상 전기 발생시 금속피막저항(8)의 발열로 저온납(9)이 용융됨과 동시에 탄동스프링(10)이 복원되며 단락토록 된 것을 특징으로 하는 보안기용 플러그의 과전압 및 과전류 단락장치.
