Abstract
외부로부터의 고주파잡음에 대한 전파장해내성 대책을 손감되는 일이 없이, 솔레노이드 구동등에 기인하는 신호입력 출력시스템의 그라운드전위의 변동방지를 도모한다. 제1그라운드패턴(57)과, 이 패턴에 EMI용 콘덴서(63)를 개재하여 접속되는 제2그라운드패턴(58)을 설치하고, 제2그라운드패턴(58)에 신호입력선(47∼49)을 EMI용 콘덴서(67∼69)을 개재하여 접속함과 동시에 소전류용 접지선(52)을 EMI용 콘덴서를 개재하지 않고 직접접속하고, 제1그라운드패턴(57)에 대전류용 접지선(55)를 EMI용 콘덴서(65)를 개재하여 접속한다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 차에 적재용 제어장치의 EMI용 접지구조를 나타낸 종래예, 제2도는 본 발명의 실시형태의 한예를 나타낸 구성도.
