본 고안은 모니터의 CRT(CATHODE-RAY TUBE)앞에 설치되는 보안경을 겸하는 전자파차단휠터에 있어 휠터프레임에 휠터판이 결합되도록 하는 구조에 관한 것으로서, 특히 외부와의 완전한 밀폐가 이루어지게 하고, 보다 수월한 휠터판 결합작업을 도모하도록 하므로서 제조비용의 절감을 도모할 수 있도록 고안된 모니터용 전자파차단휠터의 휠터판결합구조에 관한 것이다. 종래, 모니터에는 보안경만이 설치되어 사용되었으므로 전자파가 CRT로부터 방출되어 건강훼손을 초래하였기 때문에 최근 보안경을 겸하는 전자파차단휠터가 모니터 전면에 설치되도록 하므로서 전자방출에 따른 건강훼손을 미연에 방지하도록 개발되고 있다. 따라서 보안경만이 설치되는 종래의 경우 그의 프레임과 완전히 밀폐되지 않는 구조를 이루어도 본연의 기능수행을 할 수 있었기 때문에 보안경판이 프레임의 이탈방지편내에 끼워 결합시키는 수단이 사용되었다. 그러므로 보안경의 결합시 많은 노력이 필요로 되었을 뿐만 아니라 이탈방지편 내측으로 보안경이 쉽게 끼워지지 않으므로서 작업능률의 저하를 비롯하여 생산성 저하가 초래되었다.The present invention relates to a structure in which a filter plate is coupled to a filter frame in an electromagnetic shielding filter that also serves as a safety glasses installed in front of a CRT (CATHODE-RAY TUBE) of a monitor. The present invention relates to a filter plate coupling structure of an electromagnetic wave blocking filter for a monitor designed to reduce manufacturing costs by promoting a plate coupling operation. Conventionally, since only the safety glasses are installed and used in the monitor, electromagnetic waves are emitted from the CRT, causing health damage. Therefore, the electromagnetic wave blocking filter, which also serves as a safety glasses, is recently installed on the front of the monitor to prevent health damage due to electromagnetic emission. have. Therefore, in the conventional case where only the safety glasses are installed, even if the frame is not completely enclosed with its frame, it is possible to perform its original function, and thus the means for fitting the safety glasses into the separation prevention piece of the frame is used. Therefore, not only a lot of effort was required when the safety glasses were combined, but the safety glasses were not easily fitted inside the separation prevention piece, resulting in a decrease in productivity and productivity.

또한, 프라스틱 재질인 모니터의 캐비넷트 및 보안경 자체에 돌기와 결착용의 슬라이드 홀이 형성되는 구조를 가지므로서 상기 돌기와 홀을 형성하기 위한 복잡한 사이드 코어(side core)를 구비하는 사출 금형으로 프레임을 형성하여야 하였기 때문에 사출 금형자체에 사이드코어가 필요로 되므로 고가의 금형비가 소요되고 사출생산성이 저하되므로서 제조원가상승이 초래되었고, 따라서 제품가격 상승을 야기하게 하였다. 그러므로 종전의 보안경 결합수단과 동일한 수단으로 보안경을 겸하는 전자 차단휠터판을 결합시키게 되면 휠터프레임과 틈새가 발생되어 외부로 전자파 방출이 발생하는 한편 외부공간으로부터 먼지나 습기등의 이물질이 내부로 침투하게 되고 조립성 저하 및 금형비 상승에 따른 제조원가 상승으로 인해 경쟁력의 약화가 초래될 뿐만 아니라 제품신뢰성이 극해 저조하게 되는 문제점을 수반하게 된다.In addition, the frame is formed of an injection mold having a complex side core for forming the protrusions and holes, since the slide holes for protrusions and binding are formed in the cabinet of the plastic monitor and the safety glasses themselves. Since side cores are required in the injection mold itself, expensive mold costs are required and injection productivity is reduced, resulting in an increase in manufacturing cost, thus causing a rise in product prices. Therefore, when the electronic shielding filter plate that serves as the safety glasses is combined with the same means as the conventional safety glasses coupling means, a gap is generated between the filter frame and the electromagnetic wave to the outside, and foreign matter such as dust or moisture from the external space penetrates into the interior. In addition, the manufacturing cost increases due to the decrease in assemblability and the increase in the mold cost, which leads to the weakening of the competitiveness and the extremely low product reliability.

본 고안은 상기한 점을 감안하여 보안경을 겸하는 전자파차단휠터의 휠터판이 휠터프레임에 완전밀폐되는 상태로 결합되도록 하므로서 전자파 방출이 야기되지 않게 되는 휠터판결합 구조를 제공하려는 데 그 주된 목적이 있는 것이고, 다른목적은 양호하고 손쉬운 조립을 도모하게 하여 생산성 향상을 도모하는 한편 사이드코어를 사용하지 않는 금형으로도 제조가능하게 하여 제조비 절감에 따른 저렴한 제품을 보급시킬수 있게 하려는데 있다. 본 고안은 이러한 목적을 달성시키기 위하여 휠터판과 휠터프레임이 강력양면 접착테이프로 접착되는 수단으로 결합되는 구조를 이루도록 하되 휠터프레임의 정위치에 접착결합될 수 있도록 하므로서 보다 신속 간편하게 결합시킬수 있고 휠터프레임가 밀폐 기능을 완벽히 수행할 수 있도록 한 것으로, 이하 첨부된 실시도면에 의거하여 보다 상세히 설명하면 다음과 같다.The present invention has been made in view of the above point, and the main purpose of providing a filter plate coupling structure in which electromagnetic wave emission is not caused by allowing the filter plate of the electromagnetic shielding filter which also serves as a safety goggle to be completely enclosed to the filter frame. Another purpose is to improve productivity by facilitating good and easy assembly, and to make it possible to manufacture a mold without using side cores, so that it is possible to spread a cheap product by reducing manufacturing costs. In order to achieve the above object, the present invention has a structure in which the filter plate and the filter frame are joined by means of bonding with strong double-sided adhesive tape, but can be easily and quickly combined by allowing the filter to be bonded to the right position of the filter frame. In order to fully perform the sealing function, it will be described below in more detail based on the accompanying drawings.

본 고안은 모니터(1)의 CRT(2)앞쪽으로 설치되는 전자파차단휠터(10)의 휠터프레임(11)에 사각공(12)이 뚫려있고 이 사각공(12)이 밀폐되도록 휠터판(13)이 부착 설치된다. 휠터프레임(11)의 사각공(12) 내주면은 평내주면(14)을 이루도록 되어 있고 그 외측으로는 접착홈(15)이 형성되도록 가이드편(16)이 돌출형성되어 있다. 상기 접착홈(15)에는 큐션(cusion)특성을 가진 양면테이프(17)가 접착되도록 되어있고 상기 양면테이프(17)는 두 개의 테이프를 서로 붙일 수 있는 또 다른 테이프가 중간에 부가되어 만들어져 있기 때문에 큐션 특성을 가진다. 또한, 상기 양면 테이프의 외측으로는 투명한 휠터판(13)의 외주면이 접착되어 고정되도록 되어 있다. 양면 테이프(17)는 접착홈(15)의 깊이와 동일한 두께의 것이 접착되므로 여기에 휠터판(13)이 접착 고정되면 휠터판(13)의 주면과 휠터프레임(11)의 평내주면(14)은 상호 밀접되어 틈새없이 결합되게 된다. 미설명 부호(3),(3')는 결착구이고, (4)는 상부마운트, (5)는 나사보스이며, (6)은 고정나사이다. 이와같이 구성된 본 고안은 접착홈(15)에 양면테이프(17)를 붙이고 그 위쪽으로 휠터판(13)이 접착되도록 가압하여 부착시키는 것이므로 휠터프레임(11)에 휠터판(13)을 결합시키는 작업을 매우 신속 간편하게 할 수 있다.According to the present invention, a square hole 12 is drilled in the filter frame 11 of the electromagnetic wave blocking filter 10 installed in front of the CRT (2) of the monitor (1), and the filter plate (13) is sealed. ) Is attached to the installation. The inner circumferential surface of the square hole 12 of the filter frame 11 is to form a flat inner circumferential surface 14, and the guide piece 16 protrudes from the outer side so that the adhesive groove 15 is formed. Since the double-sided tape 17 having the cushion characteristic is adhered to the adhesive groove 15, and the double-sided tape 17 is made by adding another tape in the middle to attach two tapes to each other. It has a curation characteristic. In addition, the outer circumferential surface of the transparent filter plate plate 13 is bonded to and fixed to the outside of the double-sided tape. Since the double-sided tape 17 has a thickness equal to the depth of the adhesive groove 15, when the wheeler plate 13 is adhesively fixed thereto, the main surface of the wheeler plate 13 and the flat inner surface 14 of the wheeler frame 11 may be bonded thereto. Are closely related to each other and combined without gaps. Reference numerals (3) and (3 ') are binding holes, (4) is an upper mount, (5) is a screw boss, and (6) is a fixing screw. The present invention configured as described above attaches the double-sided tape 17 to the adhesive groove 15 and presses and attaches the filter plate 13 so that the filter plate 13 is adhered thereon so that the work of coupling the filter plate 13 to the filter frame 11 is performed. It's very quick and easy.

또한, 휠터판(13) 결합작업에 있어 접착홈(15)이 있으므로 양면테이프(17)를 정확한 위치에 접착시킬 수 있게 되며, 아울러서 휠터판(13)은 접착홈(15) 바깥위치에 가이드편(16)이 있기 때문에 상기 가이드편(16) 내측으로 휠터판(13)을 삽입시켜 양면테이프(17)에 접착되도록 하므로서 사각공(12)의 정위치에 휠터판(13)을 결합시킬 수 있다. 그리고 양면테이프(17)는 강력한 접착력을 가진 것이 사용되며 접착홈(15) 깊이만큼의 두께를 가지므로 어느 정도의 큐션력을 가지게 되는 한편 접착시키기 위하여 휠터판(13)을 가압시킬 때 가압력을 일부 흡수하는 동시에 역반발력이 작용되므로서 틈새 발생됨이 없이 강력한 접착이 도모되고, 전외곽면이 모두가 접착되므로서 외부와의 완벽한 밀폐를 도모할 수 있게 된다. 한편, 휠터판(13)이 안쪽에서 그대로 접차되어 결합되는 구조를 이루기 때문에 휠터프레임(11)의 구조가 사이드코어를 사용하지 않아도 되는 금형으로 사출성형시킬 수 있는 구조로 형성시킬 수 있게 되므로 금형비 절감을 도모할 수 있게 된다.In addition, since there is an adhesive groove 15 in the coupling operation of the filter plate plate 13, the double-sided tape 17 can be adhered to the correct position. In addition, the filter plate plate 13 is a guide piece in the outside position of the adhesive groove 15. Since there is a 16, the filter plate 13 may be coupled to the double-sided tape 17 by inserting the filter plate 13 into the guide piece 16 so as to adhere to the double-sided tape 17. . And since the double-sided tape 17 has a strong adhesive force is used and has the thickness as much as the depth of the adhesive groove 15 has a certain degree of cushioning force while pressing the filter plate 13 in order to adhere to a part of the pressing force At the same time, the repulsive force is absorbed and strong adhesion is achieved without generating a gap, and the front and outer surfaces are all bonded together, thereby achieving a perfect seal with the outside. On the other hand, since the filter plate 13 is folded in contact with the inside to form a structure, the structure of the filter frame 11 can be formed into a structure that can be injection molded into a mold that does not require a side core, thereby reducing mold cost It becomes possible to plan.

이상의 설명에 따르면 본 고안에 의해 휠터판(13)을 휠터프레임(11)에 보다 신속 간편하게 결합시킬 수 있는 작업성을 제공하게 되므로 생상성 향상을 도모하게 되는 한편 외부와의 밀폐기능이 부여되므로 모니터(1)에 전자파차단휠터(10)의 설치시 외부로부터 사각공(12)을 통해 먼지나 습기등 이물질의 유입이 봉쇄되기 때문에 제품 신뢰향상을 꾀할 수 있게 하는 효과를 제공하게 되는 동시에 금형비절감에 따른 원가절감을 도모하게 하는 효과를 제공하게 된다.According to the above description, since the present invention provides workability that allows the filter panel plate 13 to be coupled to the filter frame 11 more quickly and easily, the productivity can be improved while the sealing function is provided to the outside. 1) Since the inflow of foreign matter such as dust or moisture is blocked from the outside through the square hole 12 when the electromagnetic wave blocking filter 10 is installed, it provides an effect of improving the reliability of the product and at the same time reducing the mold cost. It will provide the effect of cost reduction.
