Abstract

본 발명은 셀프에서 방출되는 전자파를 차단하기 위한 것으로, 특히 셀프에 일정간격으로 배설된 유니트들 간의 틈새로 방출되는 전자파를 차단하여 전자파에 의한 주변의 전자기기들의 오동작을 효과적으로 방지함과 동시에 EMI 규제에 효과적으로 대처할 수 있도록 하는 유니트에 전자파 차폐스프링이 설치된 셀프에 관한 것이다.
상기한 본 발명의 구조는 상기 셀프(10)에 일정간격 배설되는 유니트(20)에 구성되는 전면판(30)의 배면 일측에 세로방향으로 길게 돌출형성되고, 그 일측면에 길이방향으로 고정홈(112)이 형성된 돌출편(111)과, 상기 돌출편(111)의 외주의 전면에 차폐스프링(20)이 씌워져 셀프의 전방으로 방출되는 전자파를 차단하도록 한 것을 특징으로 한다.
