본 고안은 음극선관의 방폭밴드에 관한 것으로서, 특히 음극선관에 결합될때에 압축력이 증가되고, 미끄럼이 방지될 수 있도록 개량한 것에 관한 것이다.The present invention relates to an explosion-proof band of a cathode ray tube, and more particularly, to an improvement in that the compressive force is increased when the cathode ray tube is coupled and slippage is prevented.
일반적으로 음극선관의 방폭밴드(B)는 제1도에 도시된 바와 같이 음극선관의 최대 외주 장력부 즉, 음극선관의 패널(P)와 펀널(F)이 접합되는 부위를 소정의 장력을 가지고 감쌀 수 있도록 사각형으로 형성되어서 음극선관에 큰 충격이 가해졌을 때 상기 최대 외주 장력부에서 충격으로 발생한 크랙(crack)의 진행을 억제하여 음극선관의 폭축을 방지할 수 있는 것이다. 또한 상기 방폭밴드(B)의 네 모서리부에서는 고정러그(L)가 부착되어 음극선관의 케이스(도면에는 도시되어 있지 않음)에 용이하게 고정할수 있도록 되어 있다.In general, the explosion-proof band B of the cathode ray tube has a predetermined tension at the maximum outer peripheral tension portion of the cathode ray tube, that is, the portion where the panel P and the funnel F of the cathode ray tube are joined. It is formed in a rectangular shape so as to wrap, and when a large impact is applied to the cathode ray tube, it is possible to prevent the shrinkage of the cathode ray tube by suppressing the progress of a crack generated by the impact at the maximum outer peripheral tension portion. In addition, at four corners of the explosion-proof band (B), a fixing lug (L) is attached so that it can be easily fixed to the case (not shown) of the cathode ray tube.
이러한 방폭밴드(B)는 대체로 음극선관의 제조 공정의 말기에 음극선관에 설치되게 되는바, 상기 방폭밴드를 충분히 가열하여 전체적으로 열팽창되게 한 후 패널(P)과 펀널(F)이 접합부에 압입시키면 냉각과 함께 밴드(B)가 수축되어 견고히 고정된다.Such an explosion-proof band (B) is generally installed in the cathode ray tube at the end of the cathode ray tube manufacturing process. When the explosion-proof band is sufficiently heated to thermally expand overall, the panel (P) and the funnel (F) are pressed into the joints. With cooling, the band B is contracted and fixed firmly.
그러나 이와 같은 방폭밴드(B)는 일정두께를 갖는 판상의 몸체로 형성되어 있기 때문에 패널 외측면과 접촉 고정될때에 고 인장력에 의한 미끄럼이 발생되어 정확한 위치에 고정되지 못하는 경우가 많았다. 이와 같이 되면 소정의 고정부(즉 케이스)에 대한 음극선관의 장착 상태가 불안정하고 부정확하게 된다.However, since the explosion-proof band (B) is formed of a plate-like body having a certain thickness, when the contact with the panel outer surface is fixed by the high tension force is often generated because it is not fixed in the correct position. In this case, the mounting state of the cathode ray tube to the predetermined fixing part (namely, case) becomes unstable and inaccurate.
따라서 본 고안은 음극선관과 밴드간의 미끄럼을 방지하여 이들의 조립시 상대적 위치가 정확하게 위치될수 있도록 하며, 음극선관의 안전도를 향상시킨 음극선관의 방폭밴드를 제공함에 그 목적이 있다.Therefore, the present invention is to prevent the slip between the cathode ray tube and the band so that the relative position can be accurately positioned during their assembly, and to provide an explosion-proof band of the cathode ray tube to improve the safety of the cathode ray tube.
상기 목적을 달성하기 위하여 본 고안은 패널의 외주면을 감싸도록 된 음극선관의 방폭밴드에 있어서, 상기 패널의 외주면과 접촉하는 밴드에 몸체 내측면에 요철부를 형성하여된 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that in the explosion-proof band of the cathode ray tube to surround the outer circumferential surface of the panel, an uneven portion is formed on the inner surface of the body in the band in contact with the outer circumferential surface of the panel.
이하 첨부된 도면을 참조하여 본 고안의 한 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 따른 음극선관의 방폭밴드(B)는 제2도 및 제3도에 도시된 바와 같이 음극선관의 패널(P)의 외주면을 감싸는 띠상의 밴드몸체와 그 모서리부에 고정러그(L)가 용접되어 구성되는데, 상기 패널(P)의 외주면에 접촉하는 상기 밴드몸체(Ba)의 내측면에는 요철부(E)가 형성되어 있다.Explosion-proof band (B) of the cathode ray tube according to the present invention is a band-like band body surrounding the outer circumferential surface of the panel (P) of the cathode ray tube as shown in Figs. Is welded, and an uneven portion E is formed on an inner side surface of the band body Ba in contact with the outer circumferential surface of the panel P.
이와 같이 구성된 음극선관의 방폭밴드(B)는 패널(P)의 외주면에 열박음 된후 미끄럼에 의한 이탈을 방지할 수 있다.Explosion-proof band (B) of the cathode ray tube configured as described above can be prevented from slipping after being shrinked to the outer peripheral surface of the panel (P).
즉 밴드몸체(Ba)를 충분히 가열하여 열팽창 시킨 후 패널(P)의 외주면에 압입하면 방폭밴드(B)는 냉각되면서 상기 패널(P)의 외주면에 견고하게 고정되게 되는데, 이때에 패널(P)의 외주면에 접촉하는 밴드 몸체(Ba)의 내측면에는 요철부(E)가 형성되어 있으므로 패널 외주면과의 마찰력이 증대되어 미끄럼을 방지할 수 있는 것이다.That is, when the band body Ba is sufficiently heated and thermally expanded and pressed into the outer peripheral surface of the panel P, the explosion-proof band B is cooled and firmly fixed to the outer peripheral surface of the panel P. At this time, the panel P Since the concave-convex portion E is formed on the inner surface of the band body Ba in contact with the outer circumferential surface thereof, the frictional force with the outer circumferential surface of the panel is increased to prevent slippage.
또한 충격에 의하여 음극선관에 크랙이 발생 되었을때 크랙이 발생 되었을때 크랙이 넓어지려는 역방향으로 가열 후 수축된 방폭밴드(B)에는 항 인장력이 작용하고 있어 크랙의 진행을 방지할 수 있다. 그리고 음극선관의 패널(P) 외주면과 방폭밴드(B)의 미끄럼이 발생되지 않으므로 인하여 밴드의 모서리부에 고착된 고정러그(L)의 상대적 위치가 정확하게 유지되어 도면에는 도시되어 있지 않으나, 케이스에 상기 고정러그(L)가 고정될때에 음극선관의 장착 상태가 정확하게 된다.In addition, when the crack is generated in the cathode ray tube due to the impact, the anti-tensile force is applied to the explosion-proof band (B) contracted after heating in the reverse direction to expand the crack when the crack is generated, thereby preventing the progress of the crack. And since the sliding of the panel (P) outer peripheral surface of the cathode ray tube and the explosion-proof band (B) does not occur, the relative position of the fixing lug (L) fixed to the edge of the band is accurately maintained and not shown in the drawing, When the fixing lug (L) is fixed, the mounting state of the cathode ray tube is accurate.
이와 같이 본 고안은 패널의 외주면과 접촉하는 방폭밴드의 내측면에 요철부를 형성함으로써 방폭에 대한 한층 높은 안전도를 얻을 수 있다.In this way, the present invention can obtain a higher degree of safety against explosion by forming an uneven portion on the inner surface of the explosion-proof band in contact with the outer peripheral surface of the panel.
