Abstract

본 발명은 자동차의 전자 회로에 메인 파워 릴레이를 통하여 전원을 공급할 경우 상기 파워 내부에 전류 차단 소자(CIRCUIT BRAKE)를 부착하여 부하가 단락 또는 과부하가 걸려 메인 파워 릴레이의 접점에 과도한 전류가 흐름으로써 파워 릴레이가 손상되는 것을 방지하기 위한 파워 릴레이 손상 방지 장치에 관한 것으로, 파워 릴레이 내부에 전류 차단 소자(CIRCUIT BRAKE)를 부착하고, 상기 전류 차단 소자의 전류 차단값은 상기 파워 릴레이의 접점의 허용 전류 용량과 동일하게 설정하며, 상기 전류 차단 소자를 상기 퍼워 릴레이의 접점과 부하사이에 직렬로 접속하여, 부하에 허용치 이상의 과전류가 흐르면 자동으로 상기 파워 릴레이의 접점과 부하를 차단함으로써 파워 릴레이의 접점을 보호하는 효과를 가진다.According to the present invention, when a power is supplied to an electronic circuit of an automobile through a main power relay, a current breaking element (CIRCUIT BRAKE) is attached to the inside of the power, so that a load is shorted or overloaded so that excessive current flows to a contact of the main power relay. The present invention relates to a power relay damage preventing device for preventing damage to a relay, wherein a current breaking element (CIRCUIT BRAKE) is attached to a power relay, and the current breaking value of the current blocking element is a permissible current capacity of a contact of the power relay. The current blocking element is connected in series between the contact point of the relay and the load, and the contact point of the power relay is protected by automatically cutting off the contact point of the power relay and the load when an overcurrent exceeding the allowable value flows to the load. Has the effect of
