21 : (방폭밴드)의 몸체 22 : (방폭밴드의)고정러그21: Body of (explosion proof band) 22: Fixed lug (of explosion proof band)

본 고안은 음극선관용 방폭밴드에 관한 것으로서, 상세하게는 밴드의 몸체와 고정러그를 일체로 형성하여 그 제작이 용이하도록 개량한 것에 관한 것이다.The present invention relates to an explosion-proof band for a cathode ray tube, and more particularly, to an improved body to easily form the body and the fixing lug of the band.

음극선관용 방폭밴드(10)는 제 1 도에 도시된 바와 같이 음극선관(1)의 최대 외주장력부 즉 음극선관의 패널(2)과 판넬(3)이 접합되는 부위를 소정의 인장응력을 가지고 감쌀수 있도록 사각형으로 형성되어서 음극선관에 큰 충격이 가하여 졌을때 상기 최대 외주장력부에서 발생한 크랙(Crack)의 진행을 억제하여 음극선관(1)의 푹축을 방지할수 있는 것이다. 또한 상기 방폭밴드(10)의 네 모서리에는 고정러그가 부착되어 음극선관(1)의 케이스(도면에는 도시되어 있지 않음)에 용이하게 고정할수 있도록 되어 있다.As shown in FIG. 1, the explosion-proof band 10 for the cathode ray tube has a predetermined tensile stress at the maximum outer tension portion of the cathode ray tube 1, that is, the portion where the panel 2 and the panel 3 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 collapse of the cathode ray tube 1 by suppressing the progress of cracks generated in the maximum outer tension portion. In addition, the four edges of the explosion-proof band 10 is attached to the fixing lug so that it can be easily fixed to the case (not shown) of the cathode ray tube 1.

이러한 종래의 방폭밴드(10)는 기제작된 별개의 밴드몸체(11)의 각 모서리부에 고정러그(12)를 용접 고정하여 제작하도록 되어 있으므로 작업공수가 증가할 뿐만 아니라 음극선관의 케이스에 고정러그(12)를 고정 할때에 음극선관의 하중이 작용하여 밴드몸체(11)에 용접된 고정러그(12)이 용접부위가 떨어져 음극선관의 고정상태가 매우 불량하게 된다.Since the conventional explosion-proof band 10 is manufactured by welding and fixing the fixing lug 12 at each corner of the separate band body 11, which is manufactured, not only increases the labor but also fixed to the case of the cathode ray tube. When the lug 12 is fixed, the load of the cathode ray tube is applied, so that the fixing lug 12 welded to the band body 11 is separated from the welded portion, so that the state of the cathode ray tube is very poor.

따라서 본 고안은 밴드의 몸체와 고정러그를 일체로 형성하여 용접에 의한 취약부위가 발생하지 않도록 하고 작업공수를 대폭 줄일수 있는 음극선관용 방폭밴드를 제공함에 그 목적이 있다.Therefore, the present invention has an object of providing an explosion-proof band for cathode ray tubes that can be formed integrally with the body of the band and the fixing lug so that the weak spots due to welding do not occur and can significantly reduce the labor.

상기 그 목적을 달성하기 위하여 본 고안은 패널의 외주면을 감싸는 몸체와 그 모서리에 고정러그가 구비된 음극선관용 방폭밴드에 있어서, 상기 밴드의 몸체의 각 모서리부에 후단과 동일 평면상으로 연장되도록 복수의 고정러그를 일체로 형성하여 된 점에 그 특징이 있다.In order to achieve the above object, the present invention is a explosion-proof band for cathode ray tube provided with a body surrounding the outer circumferential surface of the panel and a fixing lug at its corner, a plurality of edges extending in the same plane as the rear end at each corner of the body of the band It is characterized by the fact that the fixing lug is formed integrally.

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 음극선관용 방폭밴드(20)는 제 2 도에 도시된 바와 같이 음극선관의 패널과 펀넬이 접합되는 부위의 최대외주 장력부를 감싸는 몸체(21)와 그 모서리부에 결합되는 고정러그(22)를 일체로 형성하되, 고정러그(22)의 상면(22a)하부로부터 점차 적어지는 보강부(22b)가 형성된 구성이다. 이때에 상기 몸체(21)와 고정러그(22)를 일체로 형성하기 위해서는 상기 방폭밴드(20)의 재질이 종래의 스틸(steel)보다는 스틸과 연산율, 인장강도, 굽힌강도 및 열팽창계수가 유사한 난연성 재질을 사용함이 바람직하다.Explosion-proof band 20 for the cathode ray tube according to the present invention is the body 21 surrounding the maximum outer peripheral tension portion of the panel and the funnel is joined to the panel of the cathode ray tube and the fixing lug coupled to the corner ( 22 is formed integrally, but the reinforcement part 22b which gradually decreases from the lower surface 22a of the fixing lug 22 is formed. At this time, in order to integrally form the body 21 and the fixing lug 22, the material of the explosion-proof band 20 is similar to the steel and the calculation rate, tensile strength, bending strength and thermal expansion coefficient similar to the conventional steel (steel) It is preferable to use a flame retardant material.

이와같이 밴드의 몸체(21)와 고정러그(22)와 일체로 형성된 방폭밴드(20)는 제작공수를 대폭 줄일수 있을 뿐만아니라, 용접불량으로 인한 불량을 대폭 줄일수 있다. 즉 밴드의 몸체(21)와 고정러그(22)를 일체로 형성하기 위해서는 일반적으로 다이케스팅(die casting)하거나, 사출 성형하게 되는데 이때에 다이(die)사출금형의 제작시에 밴드의 몸체(21)에 대한 고정러그(22)의 위치가 한정되게 되므로 종래의 고정러그의 위치 불량이나 용접 불량에 의한 불량율을 대폭 줄일수 있는 것이다.In this way, the explosion-proof band 20 formed integrally with the band body 21 and the fixing lug 22 can not only significantly reduce the manufacturing labor but also significantly reduce the defects due to poor welding. That is, in order to integrally form the band body 21 and the fixing lug 22, die casting or injection molding is generally performed. In this case, the band body 21 at the time of manufacturing a die injection mold. Since the position of the fixing lug 22 with respect to is limited, it is possible to drastically reduce the defective rate due to the poor position or welding of the conventional fixing lug.

또한 상기 밴드의 몸체(21)에 일체로 형성된 고정러그(22)는 그 상면으로부터 멀어질수도록 점차 적어지는 보강부(22b)가 형성되어 있으므로 밴드의 몸체(21)에 고정러그(22)가 견고하게 부착될 뿐만 아니라 본 고안의 방폭밴드(20)가 채용된 음극선관을 케이스에 장착한후 흔들림이 발생하지 않게 된다.In addition, since the fixing lugs 22 formed integrally with the band body 21 are formed with a reinforcing part 22b which gradually decreases from the upper surface thereof, the fixing lugs 22 are firmly fixed to the body 21 of the band. In addition, the shake does not occur after the cathode ray tube employing the explosion-proof band 20 of the present invention is attached to the case.

이와같이 본 고안 음극선관용 방폭밴드는 밴드의 몸체와 고정러그를 일체로 형성함으로써 작업공수를 줄일수 있을 뿐만 아니라 양품율을 대폭 향상시킬수 있는 실용적인 고안이다.As described above, the explosion-proof band for the cathode ray tube is a practical design that can not only reduce the labor but also significantly improve the yield rate by integrally forming the band body and the fixing lug.
