본 고안은 TV등에 설치하는 튜너의 차폐장치에 관한 것으로서, 특히 금속판의 일체형으로 된 차폐케이스의 산하판 덮개는 경첩으로 연결하여 덮개에 형성된 걸림고리는 차폐케이스 몸체의 걸림고리에 맞물려서 덮개는 밀봉되게 하고, 회로기판은 고정돌기와 지지편으로 고정할 수 있도록 한 튜너 차폐장치에 관한 것이다.The present invention relates to a shielding device of a tuner installed in a TV, etc. In particular, the cover of the lower part of the shielding case integrally formed of a metal plate is connected with a hinge so that the hook formed on the cover is engaged with the hooking ring of the shielding case body so that the cover is sealed. In addition, the circuit board relates to a tuner shield that can be fixed by a fixing projection and a support piece.
종래 TV등에 사용하는 차폐케이스는 4각형의 몸체 상하에 별개로된 상판과 하판을 덮어서 용접이나 납땜하여 밀봉하였다.The shielding case used in conventional TVs and the like is sealed by welding or soldering the upper and lower plates separated by upper and lower sides of a quadrilateral body.
그러므로 상판과 하판의 주위면을 구부려서 납땜부위를 형성해야 하고 고정작업에 많은 시간이 소요되었다.Therefore, it is necessary to bend the peripheral surface of the upper plate and the lower plate to form a soldering part, and a lot of time was required for fixing.
또한 차폐 케이스 내부에 설치하는 회로기판은 별도의 고정편으로 고정하였으므로 고정해야 할 부분이 많아서 고정작업이 번거로워서 생산 능률이 저하되는 문제점이 있었다.In addition, since the circuit board to be installed inside the shielding case is fixed by a separate fixing piece, there are a lot of parts to be fixed, which is troublesome to fix the work, and there is a problem that the production efficiency is lowered.
본 고안은 이와 같은 문제점을 해결하기 위하여 차폐 케이스의 몸체는 일체로 형어하되 상하판 덮개는 걸림고리로 고정할 수 있게하고, 회로기판을 내부 돌기에 지지되고 덮개를 덮으면 지지편이 지지 고정될 수 있도록 하여 차폐케이스의 고정 작업을 손쉽게 할 수 있어서, 작업능률을 향상하여 원가 절감을 기할 수 있게 한 것이다.The present invention is to solve the problem, the body of the shield case is integrally formed, but the upper and lower cover can be fixed by the hook, and the circuit board is supported on the inner projection and the cover so that the support piece can be supported and fixed It is possible to easily fix the shielding case, thereby improving the work efficiency to reduce the cost.
본 고안의 구성과 작용효과를 도면 참조하면서 설명하면 다음과 같다.Referring to the configuration and effect of the present invention with reference to the drawings as follows.
제1도에 의하여 본 고안의 구성은 4각형 차폐케이스 몸체(1) 상하 일측에 상하판(2, 3)을 경첩형으로 일체로 연결하고, 몸체 타측면(4)에 뚫어진 다수개의 장공(5)에 회로기판(6)의 접속핀(7)이 끼워지며, 몸체 내면의 돌기(8) 들과 상판(2) 내면의 다수개의 지지편(9)은 회로기판을 지지하고 상하판(2, 3) 양측의 걸림고리(10, 11)는 몸체 양측 외면의 걸림고리(10', 11')와 맞물려서 고정되게 한 것이다.The configuration of the present invention by FIG. 1 is connected to the upper and lower plates (2, 3) integrally hinged on the upper and lower sides of the quadrangular shielding case body (1), a plurality of holes (5) perforated on the other side of the body (5) The connecting pins 7 of the circuit board 6 are inserted into the circuit board 6, and the protrusions 8 on the inner surface of the body and the plurality of support pieces 9 on the inner surface of the upper plate 2 support the circuit board and the upper and lower plates 2, 3) Both sides of the hook ring (10, 11) is to be fixed by engaging with the hook ring (10 ', 11') of the outer surface on both sides of the body.
미설명 부호 12 : 칸막이판으로서 회로기판을 지지해준다.Unexplained Symbol 12: A partition board that supports the circuit board.
이와같이 구성된 본 고안의 차폐케이스의 재질은 금속판이며, 차폐케이스 몸체(1)와 상하판(2, 3)은 일체로 되어 있다.The shielding case of the present invention configured as described above is made of a metal plate, and the shielding case body 1 and the upper and lower plates 2 and 3 are integrated.
차폐케이스 몸체(1) 내부에 회로기판(6)을 몸체 내면의 양측돌기(8) 밑에 끼우고, 상하판(2, 3)을 덮어서 상하판의 걸림고리(10,11')와 몸체 양측 외면의 걸림고리(10,11')에 끼워서 고정하게 되면 제2도와 같이 상판(2) 내면의 다수개의 지지편(9)은 회로기판(6)면을 압압고정하므로 차폐케이스 내에 회로기판을 밀봉하게 된다.Insert the circuit board 6 into the shielding case body 1 under the both side protrusions 8 of the inner surface of the body, and cover the upper and lower plates 2 and 3 to catch the hooks 10 and 11 'of the upper and lower plates and the outer surfaces of both sides of the body. When it is fixed to the hooks (10, 11 ') of the plurality of support pieces (9) of the inner surface of the upper plate (2) as shown in Fig. 2 by pressing the circuit board 6 surface fixed to seal the circuit board in the shielding case do.
본 고안은 종래와 같이 별개의 구성된 상판과 하판을 차폐케이스에 납땜 등으로 고정하지 않고 일체로 된 차폐케이스이므로 고정공정이 간단하여 작업능률이 향상되어 제조원가를 절감할 수 있게 된 것이다.The present invention is a shielding case that is integrated without fixing the separate upper and lower plates to the shielding case by soldering as in the prior art, so that the fixing process is simple and the work efficiency is improved, thereby reducing the manufacturing cost.
