본 고안은 모니터 또는 터미널등 브라운관을 이용하는 제품에 있어서 금속제로된 보호체로서 브라운과 기판의 전자파를 차단 폐쇄하기 위해 설치 사용할 수 있게 된 것으로 결착을 용이하게 할 수 있을 뿐만 아니라 종래의 경우와 같이 고정시 납땜이나 또는 뒤틀거나 하는 작업을 하지 않고도 브라운관 기판을 안전히 고정, 보호할 수 있게 된 브라운관 기판보호장치에 관한 것이다.The present invention can be installed and used to block and close the electromagnetic waves of Brown and the board as a protector made of metal in a product using a CRT tube such as a monitor or a terminal. The present invention relates to a CRT substrate protection device which can securely fix and protect CRT substrates without soldering or twisting.

종래의 경우 브라운관 기판의 전자파를 차단폐쇄하고자 금속제 보호판을 사용하는데 있어서는 브라운관기판에형 홈을 형성하고 그 홈으로 금속제로된 보호판의형 돌출부위를 끼운 후 금속제 보호판이형상으로 브라운관 기판에 끼워진 상태에서 그 상단 돌출부위를 90°비틀어 고정하였었고 또한 금속제 보호판이 납땜이 가능한 석판등의 재질인 경우에는 브라운관 기판에 끼워진 상태에서 상단 돌출부위를 브라운관 기판 동박면에 납땜을 하여 완전히 고정하였거나 또 다른 방법으로는 아프터 서비스시 작업성이 좋게 하기 위해 금속제 보호판 안쪽에돌기를 만들어 브라운관 기판을 눌러 끼우고 잡아당겨서 이탈시킬 수 있게 한 것도 있었으나 이들은 금속제 보호판의 돌출부위를 비틀거나 납땜을 하였으므로 작업공수가 많아 시간이 다소 많이 걸렸으며 납땜으로 인해 작업성이 좋지 못했고 또한 아프터 서비스시 브라운관 기판으로부터 금속제 보호판을 이탈시키기가 어려웠을 뿐만 아니라 여러번 착탈할 경우 금속제 보호판을 새것으로 교체해야하는 번거로움이 있으며 금속제 보호판 안쪽에 돌기를 만들어 브라운관 기판을 착탈할 경우 완전히 고정이 안되는 경우가 다발하여 작업자가 한번씩 더 눌러주는 확인 과정이 필요하고 또한 돌기 부위에 따라서 브라운관 기판 삽입시 힘이 많이 들어 금속제 보호판 양편을 손으로 벌린후 브라운관 기판을 삽입하는 작업상 어려움이 있던 결점이 있었다.In the conventional case, in order to block and close the electromagnetic wave of the CRT board, in order to use a metal protective plate, Forming a groove and forming a metal After inserting the protrusion, the metal protective plate When the upper projection is fixed by 90 ° while being inserted into the CRT board in the shape, and if the metal protection plate is made of a slab or the like that can be soldered, the upper protrusion is soldered to the copper foil surface of the CRT board while it is inserted into the CRT board. To be fully secured, or alternatively, to protect the workability during after-sales service. Some of them made projections so that they could be pushed out and pulled out of the CRT board, but these were twisted or soldered on the protruding parts of the metal protection plate, which took a lot of time due to the high labor time and poor workability due to soldering. Not only was it difficult to detach the metal protective plate from the CRT board during service, but it also has the trouble of replacing the metal protective plate with a new one when it is detached several times, and when the CRT board is removed by making a protrusion inside the metal protective plate, it is often impossible to fix it completely. Therefore, the operator needed to confirm the pressing process once more, and there was a drawback in the difficulty of inserting the CRT board after opening both sides of the metal protection plate by hand due to a lot of force when inserting the CRT board according to the projection part.

따라서 본 고안은 이와같은 종래의 결점을 해결하기 위해 안출된 것으로 금속제로된 보호체의 내측면에 한쪽이 자유롭고 탄성력을 가지도록 약간의 벤딩작업을 하여 탄성편을 형성하여 브라운관 기판을 삽입시 탄성에 의해 이 탄성편이 눌리도록 하며 브라운관 기판 삽입후 원상태로 복원되어 브라운관 기판이 빠지지 않도록 하였으며 이 탄성편 밑에는 브라운관 기판이 더이상 삽입되지 않도록 지지하는 반달형 돌출부위를 형성시킨 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.Therefore, the present invention was devised to solve such a conventional drawback, and a slight bending operation was performed on one of the inner surfaces of the metal protective body so as to have a free and elastic force to form an elastic piece so that the CRT substrate could be elastically inserted. This elastic piece is pressed and restored to its original state after insertion of the CRT board so that the CRT board is not pulled out. A half-moon protrusion is formed under the elastic piece to support the CRT board from being inserted anymore. The following describes the working effect.

제품의 전면 캐비네트(1) 내로 브라운관(2), 기판(3), 보호체(4), 보호판(5)이 설치되어지는 것에 있어서, 상, 하면 후부로 보호판 고정구멍(6), (6'), (6"), (6"')이 뚫려진 금속제로된 보호체(4)에 양 내측면 상하부로는 내향되게 탄성편(7), (7'), (7"), (7"')을 각각 절곡형성시키고 또한 보호체(4)의 내측 상, 하, 좌, 우면에는 내향되게 반달형 돌출부(8), (8'), (8"), (8"')를 각각 형성시켜 보호체(4)의 보호판 고정구멍(6), (6'), (6"), (6"')내로는 보호판(5)의 상, 하단부로 돌출된 돌출편(9), (9'), (9"), (9"')을 삽입하여 보호판(5)을 고정시킨 다음, 기판(3)을 보호체(4) 내로 삽입, 탄성편(7), (7'), (7"), (7"')과 돌출부 (8), (8'), (8"), (8"')의 사이에 끼워서 결합시킨 구성인 것이다.In the case where the CRT 2, the substrate 3, the protector 4, and the protector 5 are installed into the front cabinet 1 of the product, the protector fixing holes 6 and 6 are disposed on the upper and lower surfaces. '), (6 "), (6"') and the inner side of the upper and lower sides of the metal protector (4) perforated elastic pieces (7), (7 '), (7 "), ( 7 "') are bent, respectively, and half-moon-shaped protrusions 8, 8', 8 ', and 8' 'are respectively inwardly disposed on the inner, upper, lower, left and right sides of the protector 4, respectively. Protruding pieces 9, which protrude from the upper and lower ends of the protective plate 5 into the protective plate fixing holes 6, 6 ', 6 ", and 6 " 9 '), (9 "), (9"') to fix the protection plate 5, and then insert the substrate 3 into the protection body 4, elastic pieces (7), (7 '), (7 "), (7" ') and protrusions (8), (8'), (8 "), and (8" ').

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

상기와 같은 본원은 모니터 또는 터미널 등 브라운관을 이용하는 제품중 브라운관 기판(3)의 전자파 차폐수단으로 이용되는 보호체를 금속제로 사용하는 것에 있어서 제품전면 캐비네트(1)에 브라운관(2)이 고정되어 있으며 이 브라운관(2)의 후단 끝부에는 브라운관 기판(3)에 끼워져 있을 때 브라운관 기판(3)을 보호하기 위해 금속제로된 본원의 보호체(4)를 장착하고자 할 경우에는 우선 도면 제8도에 도시된 바와같이 보호판(5)을 그 상, 하부로 돌출된 돌출판(9), (9'), (9"), (9"')을 이용, 보호체(4)의 상, 하면 후부에 뚫려진 보호판 고정구멍(6), (6'), (6"), (6"')내로 삽입시켜 보호체(4)의 내부 후면에 보호판(5)을 삽지고정시킨 다음 금속제로된 보호체(4)를 손으로 잡고 기판(3)에 눌러끼우는데 이때 기판(3)이 금속제 보호체(4)의 탄성편(7), (7'), (7"), (7"')을 눌러 양외측으로 벌어지게 하면서 밀며 점점 삽입되어져 일단 완전히 삽입되어 금속제 보호체(4)의 돌출부(8), (8'), (8"), (8"')면에 밀착되어지면 양외측으로 밀려져 있던 탄성편(7), (7'), (7"), (7"')은 복원력에 의해 다시 원래 상태로 되어 기판(3)에 걸치게 되는데 여기에서 일단 삽입된 기판(3)은 보호체(4)의 돌출부(8), (8'), (8"), (8"')에 의해 더이상 보호체(4) 안으로 삽입되지 않으며 보호체(4)의 탄성편(7), (7'), (7"), (7"')과 보호체(4)의 돌출부(8), (8'), (8"), (8"')사이에서 도면 제 10도에 도시된 바와같이 기판(3)이 완전히 고정되게 되고 또한 아프터 서비스시 기판(3)으로부터 보호체(4)를 이탈시키고자 할 때는 탄성편(7), (7'), (7"), (7"')을 양손으로 밀면서 보호체(4)를 잡아당기면 되는 것으로 본원은 종래의 경우와 같이 납땜을 하거나 뒤틀거나 하는 작업공수 삭제로 인하여 작업성이 향상되었을 뿐만 아니라 아프터 서비스시 보호체 착탈이 가능하므로 아프터 서비스 작업성이 우수하고 또한 재사용이 가능하므로 원가가 절감되게 된 것이다.As described above, the present invention uses a protective material used as an electromagnetic shielding means of the CRT board 3 of a CRT product such as a monitor or a terminal, and the CRT 2 is fixed to the front cabinet 1 of the product. At the rear end of the CRT 2, when the protection body 4 of the present application is made of metal to protect the CRT substrate 3 when it is fitted to the CRT substrate 3, it is first shown in FIG. As shown in the figure, the upper and lower rear portions of the protective member 4 are formed by using the upper and lower protruding plates 9, 9 ', 9', and 9 ', as shown. Insert the protective plate (5), (6 '), (6 "), (6"') into the protective plate (2), and insert and insert the protective plate (5) in the inner rear of the protective member (4). Hold the sieve 4 by hand and press it into the substrate 3, where the substrate 3 is the elastic pieces 7, 7 ', 7', 7 '' of the metal protective member 4 '. Press Pushed outwards and gradually inserted, once completely inserted and pushed outwards on both sides of the protrusions 8, 8 ', 8', and 8 'of the metal protector 4 The elastic pieces (7), (7 '), (7 "), and (7"') were brought back to their original state by the restoring force and span the substrate (3), where the substrate (3) once inserted is protected. The projections 8, 8 ′, 8 ″, 8 ′ of the sieve 4 are no longer inserted into the protector 4 and the elastic pieces 7, (of the protector 4) ( 7 '), 7 ", 7"' and the projections 8, 8 ', 8 ", 8"' of the protector 4 are shown in FIG. As described above, when the substrate 3 is completely fixed and the protective member 4 is to be detached from the substrate 3 during the after-service, the elastic pieces 7, 7 ', 7 ", and 7" ') By pulling the protector (4) while pushing with both hands, the present application is due to the removal of the labor maneuvering soldering or twisting as in the conventional case Not only has the workability improved, but also the detachable protection body can be removed during the after-sales service, so the after-sales service workability is excellent and can be reused, thereby reducing the cost.
