본 고안은 브라운관의 진공배기장치에 관한 것으로, 특히 진공펌프의 작동으로 브라운관을 진공시키는 배기카트의 이물 유입 방지관에 관한 것이다.The present invention relates to a vacuum exhaust device of the brown tube, and more particularly to a foreign material inflow prevention tube of the exhaust cart to vacuum the brown tube by the operation of the vacuum pump.

브라운관의 제조시에는, 그 네크부에 전자총을 장착한 후 스템으로 부터 외측으로 연장하는 배기세관을 배기카트의 배기매니폴드에 기밀상태로 끼워서 진공펌프에 의해 배기시키게 된다.In the production of the CRT, the exhaust tubule extending outward from the stem after attaching the electron gun to the neck portion is inserted into the exhaust manifold of the exhaust cart in an airtight state and exhausted by a vacuum pump.

그런데, 종래 이와같은 브라운관의 배기 공정시에 배기세관을 단순히 배기매니폴드에 기밀상태로 끼워 배기 함으로써, 배기공정 말기에 세관을 용융시켜 밀봉할때, 절단된 세관 끝부분이 매니폴드내부로 유입되거나, 배기세관의 용융절단부의 유리파편이 유입된다.However, in the conventional brown tube exhaust process, by simply exhausting the exhaust tubules in an airtight manifold, the tubular ends are introduced into the manifold when the tubules are melted and sealed at the end of the exhaust process. In this case, glass fragments are introduced into the molten cut portion of the exhaust pipe.

이러한 배기세관 또는 유리파편은 배기카트의 배기관을 폐쇄하거나 진공 펌프의 챔버내에 유입되어 배기카트의 성능을 저하시키고 빈번하게 청소하여야 하는 문제를 발생시켰다.Such exhaust tubules or glass fragments have a problem that the exhaust pipe of the exhaust cart is closed or flows into the chamber of the vacuum pump, which degrades the performance of the exhaust cart and frequently needs to be cleaned.

이러한 단점을 개선하기 위하여 종래, 매니폴드의 배기관을 만족시키거나 배기관의 초입부에 가로바를 설치하여 배기세관이 유입되는 것을 방지하도록 된 것이 있었으나, 이들 모두의 경우 유리파편의 유입은 막을 수 없었으며, 전자의 경우는 배기관의 만곡부에 배게세관이 누적되어 이를 제거하기 위해서는 배기카트를 분해하여야 하였고, 후자의 경우는 가로바와 배기관 내벽 사이에 입도가 큰 유리파편이 끼이게 되는 문제가 있었다.In order to improve this disadvantage, conventionally, to satisfy the exhaust pipe of the manifold or to install a horizontal bar at the beginning of the exhaust pipe to prevent the inflow of the exhaust customs, in all cases, the inflow of glass fragments could not be prevented. In the former case, the exhaust pipe was accumulated in the curved portion of the exhaust pipe to remove the exhaust cart, and in the latter case, the glass fragments were caught between the horizontal bar and the inner wall of the exhaust pipe.

따라서, 본 고안은 전술한 문제점을 해소하기 위하여 안출된 것으로, 그 목적은, 브라운관의 진공배기시 발생되는 이물이 진공매니폴드의 배기관이나 진공펌프의 내부로 유입되는 것을 방지하는 브라운관용 배기카트의 이물 유입 방지장치를 제공하는 것이다.Accordingly, the present invention has been made in order to solve the above problems, the object of the exhaust pipe for the brown tube to prevent foreign matter generated during the vacuum exhaust of the brown tube flows into the exhaust pipe or vacuum pump of the vacuum manifold. It is to provide a foreign material inflow prevention device.

이와같은 목적을 달성하기 위하여 본 고안은 배기카트의 진공펌프와 브라운관의 배기세관을 연결하는 매니폴드내에 분리가능하게 설치되고, 배기세관삽입공과, 주배기공 및 보조 배기공을 가지며, 배기세관의 유입방지턱이 마련된 이물유입방지관을 제공한다.In order to achieve the above object, the present invention is detachably installed in the manifold connecting the vacuum pump of the exhaust cart and the exhaust tubing of the brown tube, and has an exhaust tubing insertion hole, a main exhaust hole and an auxiliary exhaust hole. It provides a foreign material inflow prevention pipe provided with a jaw.

이하, 첨부된 도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도와 제2도에 도시된 바와같이, 본 고안의 유입방지관(10)은 외관이 일반적으로 원통형인 관의 내부 상부에 브라운관의 배기세관이 끼워지는 세관삽입공(11)보다 작은 직경으로 되고 하향으로 가면서 넓어지는 주배기공(12)이 마련되며, 세관삽입공(11)의 측벽에는 복수의 보조배기공(13)이 마련된 것이다. 세관삽입공(11)과 주배기공(12) 사이의 경계부에는 배기세관의 유입방지턱(14)이 형성된다. 그리고, 이물유입방지관(10)의 상단부에는 그보다 큰 직경의 플랜지(15)가 마련된다. 적합하기로는, 주배기관(12)의 상부, 즉 배기세관의 유입방지턱(14)에 인접한 부분의 직경은 2∼4Φ범위로 되는데, 필요에 따라서는 그보다 작거나 크게할 수도 있음은 물론이다.As shown in FIG. 1 and FIG. 2, the inflow prevention tube 10 of the present invention has a diameter smaller than that of the customs insertion hole 11 in which the exhaust tube of the brown tube is fitted on the inner upper portion of the tube, which is generally cylindrical in appearance. The main exhaust hole 12 is widened downwardly and is provided, and a plurality of auxiliary exhaust holes 13 are provided on the sidewall of the customs insertion hole 11. At the boundary between the customs insertion hole 11 and the main exhaust hole 12, an inflow prevention jaw 14 of the exhaust customs pipe is formed. And, the upper end of the foreign material inflow prevention tube 10 is provided with a flange 15 of a larger diameter. Suitably, the diameter of the upper portion of the main exhaust pipe 12, that is, the portion adjacent to the inflow stop 14 of the exhaust pipe, is in the range of 2 to 4 φ, of course, may be smaller or larger if necessary.

제3도는 본 고안에 의한 이물 유입 방지관(10)의 사용상태 개략도로서, 이물 유입방지관(10)은 매니폴드(20)의 내부에 분리가능하게 설치되는데, 이를 위하여 매니폴드(20)내의 배기관(21) 상단부에는 이물유입방지관(10)의 플랜지를 안치시키는 안치부(22)가 마련되어 있다. 본 고안의 이물유입 방지관(10)의 의경은 배기관(21)의 내경보다 작게되어 있다. 도면부호 "23"은 브라운관의 스템으로부터 연장하는 배기 세관이고, "24"는 밀봉 가스켓 또는 2-링이며, "25"는 매니폴드(20)의 상부에 나사결합되는 캡이다.3 is a schematic view of the use state of the foreign matter inflow prevention tube 10 according to the present invention, the foreign matter inflow prevention tube 10 is detachably installed in the manifold 20. An upper end portion of the exhaust pipe 21 is provided with a settling portion 22 for placing the flange of the foreign matter inflow prevention tube 10. The inner diameter of the foreign matter inflow prevention tube 10 of the present invention is smaller than the inner diameter of the exhaust pipe 21. Reference numeral 23 denotes an exhaust capillary extending from the stem of the CRT, 24 denotes a sealing gasket or 2-ring, and 25 denotes a cap that is screwed onto the top of the manifold 20.

본 고안의 사용시에는, 제3도에 도시된 바와 같이, 매니폴드(20)의 배기관(21)의 상단부에 형성된 안치부(22)에 이물유입 방지관(10)의 그 플랜지(16)을 안시켜 설치한 다음, 밀봉 가스켓(24)과 캡(25)을 차례로 끼우고, 배기세관(23)을 상부로부터 본 고안의 세관삽입공(11)에 끼운후, 캡(25)을 조임으로써 밀봉가스켓(24)이 압착되어 본 고안과 배기세관(23)을 기밀상태로 밀봉시켜 준다.In the use of the present invention, as shown in FIG. 3, the flange 16 of the foreign matter inflow prevention tube 10 is placed in the settled portion 22 formed at the upper end of the exhaust pipe 21 of the manifold 20. After installation, the sealing gasket 24 and the cap 25 are inserted in turn, and the exhaust pipe 23 is inserted into the capillary insertion hole 11 of the present invention from the top, and then the cap 25 is tightened to seal the gasket. (24) is crimped to seal the present invention and the exhaust tubing (23) in an airtight state.

배기세관(23)을 통한 브라운관의 배기공정말기에 배기세관을 가열 용융시켜 밀봉하게 되는데, 이때 절단된 세관(23)의 끝부분이 배기 매니폴드(20)내로 흡입되더라도 본 고안의 배기세관 방지턱(14)에 걸리게 되므로 더이상 유입이 방지되고, 공정완료후 쉽게 제거할 수 있게 된다. 또한, 배기세관(23)의 밀봉부로부터 발생된 유리파편중, 주배기공(12)의 직경보다 작은 것은 주배기공(12)을 통과하지 못하고 그 상부에 걸리게 되므로 공정완료후 본 고안을 분리하여 쉽게 제거할 수 있게 된다.At the end of the brown tube through the exhaust pipe 23, the exhaust pipe is sealed by heating and melting. At this time, even if the end of the cut pipe 23 is sucked into the exhaust manifold 20, the exhaust pipe of the present invention ( 14) is prevented from entering any more, and can be easily removed after completion of the process. In addition, among the glass fragments generated from the sealing portion of the exhaust pipe 23, smaller than the diameter of the main exhaust hole 12 is caught in the upper portion of the main exhaust hole 12 does not pass through, so that the present invention can be easily separated after completion of the process. It can be removed.

본 고안 이물유입방지관(10)의 보조배기공(13)은 수㎜정도로 되어 있는 주배기공(12)의 배기 효율이 낮기 때문에, 그에 보조하여 배기작용을 함으로써 배기효율을 정상수준으로 높여주는 역할을 한다.The auxiliary exhaust hole 13 of the foreign material inflow prevention tube 10 of the present invention has a low exhaust efficiency of the main exhaust hole 12, which is about several millimeters, and serves to increase the exhaust efficiency to a normal level by assisting the exhaust operation. Do it.

상술한 바와같이 본 고안은 브라운관 내부에 진공을 위한 배기시 이물이 진공펌프내부로 유입되는 것을 방지하게 되는 것이다.As described above, the present invention is to prevent foreign matter from flowing into the vacuum pump when evacuating the vacuum inside the CRT.
