3 : 실드케이스 4 : 기판고정접지부3: shield case 4: substrate fixing ground portion

본 고안은 모니터 또는 회로특성상 차폐가 요구될 때 이용되는 실드케이스와 회로기판의 결합장치에 관한 것이다.The present invention relates to a coupling device of a shield case and a circuit board used when shielding is required due to monitor or circuit characteristics.

종래에는 제3도에서와 같이 수평회로기판(31)내에 기판고정용 접지구멍을 제1도와 같이 형성하고 이 구멍의 주위에 있는 동막에 실드케이스(32)의 측벽 상단에 있는 기판고정접지부를 기판의 접지구멍에 삽입함과 동시에 저면부의 동막에 영구적으로 납땜을 실시하였으나 큰 차폐효과를 얻을 수 없고 제작 또는 수리시 납땜을 제거하거나 반복적으로 제납땜을 해야 하는 번거로움이 발생되었다.Conventionally, as shown in FIG. 3, a substrate fixing ground hole is formed in the horizontal circuit board 31 as shown in FIG. 1, and the substrate fixing ground portion at the top of the sidewall of the shield case 32 is formed on the copper film around the hole. Although the solder was permanently soldered to the copper film of the bottom part at the same time as inserting into the ground hole of the ground hole, it was not possible to obtain a large shielding effect and it was troublesome to remove the solder or repeatedly solder the solder during manufacture or repair.

따라서 이러한 문제점을 해결하기 위하여는 실드케이스의 면적을 최대한 이용할 수 있도록 상기 실드케이스의 기판 고정 접지부를 연장시켜 기판에 꽂은 다음 그 반대편으로 한번 절첩할 수 있도록 하며 기판이 타측은 실드케이스에 형성한 봉입탄성편에 걸리도록 실드케이스내에 삽입하고 기판의 해체 동작을 간편하게 하는데 있다.Therefore, in order to solve this problem, in order to make full use of the area of the shield case, the board fixing ground portion of the shield case is extended and plugged into the board so that it can be folded once to the other side, and the other side of the shield is formed in the shield case. It is inserted in the shield case so as to be caught by the elastic piece, and the disassembly operation of the substrate is simplified.

이하에서 본 고안의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail.

제1도는 모니터의 수평회로기판(1)과 실드케이스(3)를 분해한 것이다.1 is an exploded view of the horizontal circuit board 1 and the shield case 3 of the monitor.

수평회로기판(1)의 아래측 가장자리에 접지삽입공(2)과 그 이면에 동막(2a)이 형성되어 있고 이와 대응하도록 실드케이스(3)의 측벽상단에 단형을 이루는 기판고정접지부(4)가 길게 연장되어 있다.A ground insertion hole 2 is formed at the lower edge of the horizontal circuit board 1 and a copper film 2a is formed on the rear surface thereof, and the substrate fixed ground portion 4 is formed on the upper sidewall of the shield case 3 so as to correspond thereto. ) Is long.

상기 기판고정접지부(4)는 폭이 좁은 삽입단부(5)와 폭이 넓은 힌지부(6)로 대별된다.The substrate fixed ground portion 4 is roughly divided into a narrow insertion end portion 5 and a wide hinge portion 6.

상기 삽입단부(5)는 수평회로기판(1)의 접지삽입공(2)에 삽입시켜 동막(2a)에 납땜시키고 힌지부(6)는 수평회로기판(1)의 이면을 카바할 수 있도록 접을 수 있는데 필요한 길이를 갖어야 한다.The insertion end 5 is inserted into the ground insertion hole 2 of the horizontal circuit board 1 to be soldered to the copper film 2a, and the hinge part 6 is folded to cover the back surface of the horizontal circuit board 1. It must have the required length.

제2도는 수평회로기판에 실드케이스를 결합시킨 상태이다.2 is a state in which a shield case is coupled to a horizontal circuit board.

먼저 실드케이스(3)에 형성한 단형의 기판고정접지부(4)의 끝부분에 있는 삽입단부(5)를 기판의 접지 삽입구멍(2)에 삽입시킨 후 동막(2a)에 납땜하여 그라운드 시킨다.First, the insertion end 5 at the end of the short type substrate fixed ground portion 4 formed in the shield case 3 is inserted into the ground insertion hole 2 of the substrate, and then soldered to the copper film 2a to ground. .

이어서 점선위치에 있는 실드케이스(3)를 화살표방향으로 돌려 실드케이스 내측의 봉입걸림편(7)에 기판이 걸리도록 한다.Subsequently, the shield case 3 located at the dotted line position is turned in the direction of the arrow so that the substrate is caught by the encapsulation engaging piece 7 inside the shield case.

이때 실드케이스의 기판고정접지부의 힌지부(6)가 접히게 되며 수평회로기판(1)은 완전히 실드케이스(3) 내에 위치하여 차폐효과가 증대된다.At this time, the hinge part 6 of the substrate fixed ground part of the shield case is folded, and the horizontal circuit board 1 is completely located in the shield case 3, thereby increasing the shielding effect.

도면중 (8)은 CRT이다.(8) in the figure is a CRT.

이상과 같이 본 고안은 회로기판에 접지부를 끼우고 약 270˚정도 회전시켜 회로기판을 실드케이스내에 간단히 수용되게 하여 외부의 전파를 완전히 차단할 수 있게 하고 분리시에는 실드케이스의 봉입탄성편을 눌러 간단히 기판과 실드케이스를 해체할 수 있는 장점이 있는 것이다.As described above, the present invention inserts a grounding part into a circuit board and rotates it about 270 ° so that the circuit board can be easily accommodated in the shield case to completely block external radio waves. There is an advantage to dismantle the substrate and the shield case.
