Abstract

본 발명은 리밋스위치의 개폐접지구조에 관한 것으로, 종래 기술이 시스템 본체에 결합된 리밋스위치가 인쇄 회로기판에 점프선으로 납땜 마운팅되고, 상기 리밋스위치의 접지단자가 외부 접지벽에 접지되어 동작되는 구조에 따라, 리밋스위치의 접지단자와 외부 접지벽과의 접지간격이 벌어질 경우 접속이 제대로 이루어지지 못하여 시스템의 작동이 불가능해 지는 문제점을 해결하기 위하여, 본 발명은 인쇄회로 기판상에 직접 리밋스위치를 마운팅처리하고 시스템 본체의 저면에 코일스프링과 슬라이드바를 체결하여, 시스템 본체에 체결된 코일스프링이 외부 접지벽면에 압착되면서 슬라이드바가 리밋스위치의 접지단자를 밀게 되어 리밋스위치가 탄력적으로 접지되게 함으로써, 작업공수 및 불량률이 감소되는 것을 물론 접지 단자간의 거리가 일정하지 않을 경우에도 스위치의 온/오프 동작이 원활하게 되는 효과를 갖는다.The present invention relates to an open / close ground structure of a limit switch, in which a limit switch coupled to a system main body is solder-mounted on a printed circuit board by a jump line, and a ground terminal of the limit switch is operated by being grounded to an external ground wall. According to the present invention, in order to solve the problem that the connection is not made properly and the operation of the system becomes impossible when the ground distance between the ground terminal of the limit switch and the external ground wall increases, the present invention provides a limit switch directly on a printed circuit board. By mounting the coil spring and the slide bar on the bottom of the system main body, the coil spring is fastened to the external ground wall and the slide bar pushes the ground terminal of the limit switch so that the limit switch is elastically grounded. Reduced labor and defective rate, as well as the distance between ground terminals Even if not constant has the effect that the on / off operation of the switch is smooth.
