The present invention relates to an LCD plate fixing device for an electric and electronic device for stabilizing an unstable cooking state such as being connected again.
종래에는 전기전자기기 또는 정보통신기기에 LCD판을 설치함에 있어서 주로 외부 하우징은 샤시물로 많이 사용하여 형성하였다.Conventionally, in installing an LCD plate in an electrical or electronic device or an information communication device, an outer housing is mainly formed using a chassis.
그러나, 조립된 샤시들 간에는 조립공차 범위가 커서 LCD판의 조립상태가 안정하지 못한 문제점이 발생하였고, 그러한 샤시물간의 조립공차를 LCD판과 하우징 사이로 설치되는 반사경의 두께로 해결하였으나 이 경우에도 LCD판판이 유동할 수 있는, 여유가 존재하므로 이에따른 이동량은 프론트 회로기판과 LCD판의 접점 시이를 연결하고 있는 고무접점판에 휨이 발생되었고 이때의 훔은 접점들간의 접속상태를 나쁘게 하느 영향을 주었던 것이다.However, there was a problem in that the assembly state of the LCD plate was not stable because of the large assembly tolerance range between the assembled chassis, and the assembly tolerance between chassis objects was solved by the thickness of the reflector installed between the LCD plate and the housing. Since there is a margin to allow the plate to flow, the amount of movement is caused by the warpage of the rubber contact plate connecting the contact seam between the front circuit board and the LCD plate, which adversely affects the connection state between the stolen contacts. will be.
상기의 휨에 의한 영향력들은 통하는 전원의 흐름을 원활하게 하지 못하게 방해하므로, LCD판에서의 표시는력이 저하되는 것이다. LCD판에서의 불완전한 표시능력을 제품의 성능을 소비자가 신뢰하지 못하게 되는 문제점을 발생시키는 것이었다.The influences caused by the warping prevent the smooth flow of power through the display, so that the display force on the LCD panel is reduced. The incomplete display ability of the LCD panel caused a problem that the consumer did not trust the performance of the product.
이러한 문제점을 해결하기 위하여는 LCD판 접점과 프론트 회로기판 접점간의 조립공차가 존재하지 않도록 하는 구성이 요구되고 이러한 구성에서는 외부에서 기기에 가해지는 충격을 흡수할 수 있어야 함이 요구된 뿐만 아니라, 조립과 분해가 용이한 구성도 동시에 요구되었다.In order to solve this problem, a configuration is required such that there is no assembly tolerance between the LCD panel contacts and the front circuit board contacts, and in such a configuration, it is required to absorb shocks applied to the device from the outside. At the same time, an easy disassembly and a disassembly were also required.
