Abstract
본 발명은 유선/무선방송 선택스위치 내장튜너에 관한 것으로, 종래 전자식 유선/무선방송 절환스위치가 구성된 튜너는 전자식 유선/무선방송 절환스위치, 제어신호선, 연결케이블등이 필요해 부품비 및 작업공수가 증가하고 연결케이블에서 신호강도가 약해지는 문제점이 있고, 종래 기구식 유선/무선방송 절환스위치가 투너의 안테나 입력단까지 2 내지 3데시벨 정도 신호 강도가 약해지고 사용자가 수동으로 발송절환 스위치를 조작하므로 사용상 불편함이 따르는 문제점이 있다. 본 발명은 이와같은 종래회로의 문제점을 감안하여 전자식 또는 기구식 유선/무선방송 절환스위치를 튜너와 일체화시켜 연결케이블은 인쇄회로기판상에서 패턴으로 신호선을 처리한 유선/무선방송 선택스위치 내장튜너를 창안한 것이다.The present invention relates to a built-in tuner for wired / wireless broadcasting selection switch, and the tuner configured with a conventional electronic wired / wireless broadcasting switching switch requires an electronic wired / wireless broadcasting switching switch, a control signal line, a connection cable, etc. There is a problem that the signal strength is weak in the connecting cable, and the conventional mechanical wired / wireless broadcasting switching switch has a weak signal strength of about 2 to 3 decibels up to the antenna input of the tuner, and the user manually operates the sending switching switch, thereby causing inconvenience. There is a problem that follows. In view of the problems of the conventional circuit, the present invention integrates an electronic or mechanical wired / wireless broadcasting switching switch with a tuner, and thus, a connection cable has a built-in tuner with a wired / wireless broadcasting selection switch in which signal lines are processed in a pattern on a printed circuit board. It is.
