Description

모니터의 인쇄회로기판 처짐방지구조Monitor's printed circuit board deflection prevention structure

본 발명은 모니터에 관한 것으로, 특히, 소정부위에서의 인쇄회로기판 처짐을 탄력있게 방지할 수 있도록 하는 모니터의 인쇄회로기판 처짐방지구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitor, and more particularly, to a printed circuit board deflection prevention structure of a monitor that can flexibly prevent printed circuit board deflection at a predetermined portion.

일반적으로, 모니터는, 제1도에 도시된 바와 같이, 영상을 재생하는 브라운관(100)과, 상기 브라운관(100)의 작동을 제어할 수 있도록 상부에 수 개의 전장품이 장착되는 인쇄회로기판(200)과, 상기 인쇄회로기판(200) 및 브라운관(100)을 외부로부터 보호할 수 있도록 씌어지는 캐비닛(300)으로 구성되고, 상기 캐비닛(300)은 다시 브라운관(100)의 전면에 씌어지는 프론트커버(310)와, 상기 브라운관(100)의 배면부에 씌어지는 백커버(320)로 분리 구성되는 것으로, 이를 좀 더 구체적으로 살펴보면 다음과 같다.In general, as shown in FIG. 1, the monitor includes a CRT (100) for reproducing an image and a printed circuit board (200) having several electrical components mounted thereon to control the operation of the CRT (100). ) And the cabinet 300 which is covered to protect the printed circuit board 200 and the CRT 100 from the outside, and the cabinet 300 is again covered by the front surface of the CRT 100. It is composed of the 310 and the back cover 320, which is covered on the back portion of the CRT 100, look at this in more detail as follows.

상기 인쇄회로기판(200)은, 제2도및 제3도에 도시된 바와 같이, 테두리(410) 내측벽을 연결하는 보강리브(420)가 형성되고, 상기 테두리(410)의 모서리부분에 인쇄회로기판(200)에 통공된 체결공(431)과 일치되게 나사공(432)이 형성된 보스(430)가 구성되고, 상기 고정베이스(400)의 테두리(410) 내측 소정위치에 상기 인쇄회로기판(200)의 저면을 지지할 수 있도록 수 개의 받침대(440)가 상호 대향되게 수평돌출되고, 상기 각각의 받침대(440)와 대응된 테두리(410) 상단에 소정폭으로 역U자 형상의 탄성누름부(450)가 일체로 형성되고, 상기 테두리(410) 후부 소정위치에 상향으로 연장되고 그 단부가 상기 인쇄회로기판(200)을 고정할 수 있도록 내측으로 절곡되게 걸림편(460)이 형성되는 고정베이스(400)에 안착된다.As shown in FIGS. 2 and 3, the printed circuit board 200 is provided with a reinforcing rib 420 connecting the inner wall of the edge 410, and is printed on the edge of the edge 410. The boss 430 having a screw hole 432 is formed to match the fastening hole 431 through the circuit board 200, and the printed circuit board is located at a predetermined position inside the edge 410 of the fixed base 400. Several pedestals 440 are projected horizontally to face each other so as to support the bottom of the 200, and each of the pedestals 440 and the inverted U-shaped elastic pressing on the upper end of the corresponding edge 410 The unit 450 is integrally formed, and the engaging piece 460 is formed to extend upwardly to a predetermined position at a rear portion of the edge 410 and to be bent inwardly so that an end thereof is fixed to the printed circuit board 200. It is seated on the fixed base 400.

이와 같이 상기 고정베이스(400)에 안착되는 인쇄회로기판(200)은 고정베이스(400)의 상방에 위치된 상태에서 상기 인쇄회로기판(200)을 외곽의 테두리(410)의 소정위치에 상호 대향되게 구비되는 탄성누름부(450) 사이로 하향가압하면, 상기 인쇄회로기판(200)의 양측 단부가 상기 탄성누름부(450)를 외향으로 밀면서 삽입된다.As described above, the printed circuit board 200 mounted on the fixed base 400 faces the printed circuit board 200 at a predetermined position of an outer edge 410 in a state located above the fixed base 400. When pressed downward between the elastic pressing portion 450 is provided, both ends of the printed circuit board 200 is inserted while pushing the elastic pressing portion 450 outward.

상기와 같이 삽입되는 인쇄회로기판(200)이 테두리의 받침대(440)에 접촉하는 순간 탄성누름부(450)의 축적된 탄성이 풀리면서 상기 탄성누름부(450)는 원래의 위치로 복원되어 상기 인쇄회로기판(200)의 상면을 밀착하여 인쇄회로기판(200)은 고정된다.As the printed circuit board 200 inserted as described above contacts the pedestal 440 of the edge, the accumulated elasticity of the elastic pressing part 450 is released and the elastic pressing part 450 is restored to its original position. The printed circuit board 200 is fixed by bringing the upper surface of the printed circuit board 200 into close contact.

이러한 상태에서 상기 인쇄회로기판(200)을 슬라이드로 밀러 인쇄회로기판(200)의 선단부를 상기 걸림편(460)에 삽입시킨 후, 고정베이스(400)의 각 테두리(410)에 구비된 나사공(432)과 인쇄회로기판(200)의 체결공(431)을 나사(S)로 체결하므로써 상기 인쇄회로기판(200)은 고정베이스(400)에 고정되게 된다.In this state, the printed circuit board 200 is pushed into the slide to insert the front end of the printed circuit board 200 into the engaging piece 460, and then screw holes provided in the respective edges 410 of the fixed base 400. The printed circuit board 200 is fixed to the fixed base 400 by fastening the fastening hole 431 of the printed circuit board 200 with the screw 432.

그러나, 상기와 같이 고정베이스에 안착고정되는 인쇄회로기판에 전력용 트랜스와 같이 무거운 전장부품이 장착되면, 상기 인쇄회로기판은 평판상으로 되어 있어 기판 곳곳에서 받는 하중의 정도가 달라 장기적으로 변형을 일으키게 되는 문제점이 있었다.However, when a heavy electric component such as a power transformer is mounted on a printed circuit board fixed to a fixed base as described above, the printed circuit board has a flat plate shape, and thus the degree of load received from various parts of the board is different so that deformation can be made in the long term. There was a problem.

본 발명의 목적은 상기와 같은 종래의 문제점을 해소하기 위한 것으로, 특히, 소정부위에서의 인쇄회로기판 처짐을 탄력있게 방지할 수 있도록 하는 모니터의 인쇄회로기판 처짐방지구조를 제공함에 있다. 상기와 같은 목적을 달성하기 위하여 본 발명 모니터의 인쇄회로기판 처짐방지구조는, 소정위치에 보강리브를 연결하여 원형의 고정리브를 형성하고, 상기 보강리브 및 원형리브의 상부 선단면에 소정간격 이격되게 수 개의 완충돌기가 돌설되는 것을 특징으로 한다.SUMMARY OF THE INVENTION An object of the present invention is to solve the conventional problems as described above, and in particular, to provide a printed circuit board deflection prevention structure of a monitor that can elastically prevent the printed circuit board deflection at a predetermined portion. In order to achieve the above object, the printed circuit board sag prevention structure of the monitor of the present invention connects a reinforcing rib to a predetermined position to form a circular fixed rib, and a predetermined distance from the upper end surface of the reinforcing rib and the circular rib. It is characterized in that several buffer protrusions protrude.
