본 고안은 음극선관의 폭축을 방지하기 위해 방폭성능을 보강한 방폭보강형 음극선관의 보강밴드에 관한 것이다.The present invention relates to a reinforcing band of explosion-proof reinforced cathode ray tube reinforced with explosion-proof performance in order to prevent the shrinkage of the cathode ray tube.

음극선관의 제조과정에서는 음극선관의 내부에 들어있는 공기 또는 개스를 제거하여 음극선관의 내부를 고진공상태로 만들어주는 것이 필요하다. 그리고, 음극선관은 유리재질로 제조되기 때문에 유리의 응고후에도 수축하려고 하는 잔류응력이 음극선관내에 잔존하게 된다.In manufacturing the cathode ray tube, it is necessary to remove the air or gas contained in the cathode ray tube to make the inside of the cathode ray tube high vacuum. In addition, since the cathode ray tube is made of a glass material, a residual stress that tries to contract after glass solidification remains in the cathode ray tube.

반면에 음극선관의 외부에는 대기압이 작용하고 있어서, 결국 음극선관은 압축되어 파괴되려 하는 경향이 생기게 되는 것이다.On the other hand, atmospheric pressure is applied to the outside of the cathode ray tube, so that the cathode ray tube tends to be compressed and destroyed.

전술한 음극선관의 폭축 방지를 위해서 방폭보강형 음극선관의 보강밴드를 사용하는 경우가 많다. 제1도는 종래의 방폭보강형 음극선관의 보강 밴드를 음극선관에 장착한 상태를 도시한 도면이고, 제2도는 종래의 방폭보강형 음극선관의 보강 밴드를 도시하는 사시도이며, 또한 제3도는 제2도의 부분발췌 단면도로서, 제3a도는 버가 하향하여 형성되어 있는 경우를 도시한 도면이고, 제3b도는 버가 상향하여 형성되어 있는 경우를 도시한 도면이다.In order to prevent the deflation of the above-described cathode ray tube, a reinforcing band of an explosion-proof reinforcing cathode ray tube is often used. FIG. 1 is a view showing a state in which a reinforcing band of a conventional explosion-proof reinforcing type cathode ray tube is mounted on a cathode ray tube, and FIG. 2 is a perspective view showing a reinforcing band of a conventional explosion-proof reinforcing type cathode ray tube, and FIG. FIG. 3A is a partial cross-sectional view of FIG. 3A, and FIG. 3A is a diagram showing a case where the bur is formed downward, and FIG. 3B is a diagram showing a case where the bur is formed upward.

참조번호1은 음극선관을 지시한다. 상기 음극선관(1)은 패털(2)과 펀늘(3)로 구성되어 있다. 전술한 패널(2)의 측벽부에는 방폭보강형 음극선관의 보강밴드(4)가 장착된다. 상기 방폭보강형 음극선관의 보강밴드(4)는 기재(4')의 단부를 서로 맞대 놓은 상태에서 덮판(5)을 덮고 용접하여 이어준다. 그런데, 전술한 방폭보강형 음극선관의 보강밴드(4)의 기재(4')를 서로 맞대어 장착할 수 있도록 전달하는 과정에서는 방폭보강형 음극선관의 보강밴드(4)의 기재(4') 단부에 버(6, Burr)가 상향 또는 하향으로 형성되게 된다.Reference numeral 1 designates a cathode ray tube. The cathode ray tube 1 is composed of a pattern 2 and a funnel 3. Reinforcing band 4 of the explosion-proof reinforcing cathode ray tube is mounted on the side wall of the panel 2 described above. The reinforcing band 4 of the explosion-proof reinforcing cathode ray tube covers and welds the cover plate 5 while the ends of the substrate 4 'are opposed to each other. However, in the process of transferring the base material 4 'of the reinforcement band 4 of the explosion-proof reinforcement type cathode ray tube to be mounted against each other, the end portion of the base material 4' of the reinforcement band 4 of the explosion-proof reinforcement type cathode ray tube Ever 6 (Bur) is formed to be upward or downward.

방폭보강형 음극선관의 보강밴드(4) 기재(4')의 단부에 버가 형성되는 경우에는 덮판(5)을 덮어서 용접하는 것이 어려울 뿐만 아니라 균일하게 용접이 이루어지지 않게 된다. 한편으로, 방폭보강형 음극선관의 보강밴드(4) 기재(4')의 단부에 형성된 버(6)에 의해서 음극선관 패널(2)에 손상이 발생된다.When the burr is formed at the end of the base 4 'of the reinforcing band 4 of the explosion-proof reinforcing cathode ray tube, the cover plate 5 is not only difficult to weld but also uniformly welded. On the other hand, damage is caused to the cathode ray tube panel 2 by the burr 6 formed at the end of the base 4 'of the reinforcing band 4 of the explosion-proof reinforced cathode ray tube.

본 고안은 전술한 종래의 문제점을 해결하기 위해서 안출된 것으로서, 본 고안의 목적은 방폭보강형 음극선관의 보강밴드 기재 단부에 형성되어 있는 버를 제거함으로써 버에 의해 용접이 되지않거나 용접이 불량하게 되는 것을 방지함과 동시에 버에 의한 음극선관의 파손을 방지할 수 있는 방폭보강형 음극선관의 보강밴드를 제공하는 것이다.The present invention has been made to solve the above-mentioned conventional problems, the object of the present invention is to remove the burr formed at the end of the reinforcing band base material of the explosion-proof reinforcement cathode ray tube is not welded or poorly welded by the burr It is to provide a reinforcing band of explosion-proof reinforcement type cathode ray tube that can prevent the damage and at the same time prevent breakage of the cathode ray tube by the burr.

진술한 본 고안의 목적을 달성하기 위해서, 본 고안은, 기재의 단부를 맞대고 덮판을 용접하여 결합하는 방폭보강형 음극선관의 보강밴드에 있어서, 상기 기재의 양단부를 둥글게 형성하여 구성한 것을 특징으로 하는 방폭보강형 음극선관의 보강밴드를 제공한다.In order to achieve the stated object of the present invention, the present invention, in the reinforcing band of the explosion-proof reinforcing cathode ray tube which is joined to the end of the substrate by welding the cover plate, characterized in that the both ends of the substrate is formed rounded Provides a reinforcing band of explosion-proof reinforced cathode ray tube.

상기한 구성의 본 고안에 따르면, 방폭보강형 음극선관의 보강밴드 기재 단부에 형성된 버에 의해 용접이 잘되지 않거나 용접이 불량해지는 것을 방지할 수 있음과 동시에 전기 버에 의해 음극선관의 패널이 파손되는 것을 방지할 수도 있다.According to the present invention of the above configuration, it is possible to prevent poor welding or poor welding by the burr formed at the end of the reinforcing band base member of the explosion-proof reinforced cathode ray tube, and at the same time, the panel of the cathode ray tube is broken by the electric burr. It can also be prevented.

이하, 첨부도면을 참조하여 본 고안의 양호한 일실시예를 살펴본다.Hereinafter, with reference to the accompanying drawings looks at a preferred embodiment of the present invention.

제4도는 본 고안에 따른 방폭보강형 음극선관의 보강밴드에 대한 단면도이다. 참조번호 7은 방폭보강형 음극 선관의 보강밴드를 구성하는 기재이다. 전술한 기재(7)의 단부(8)는 절단하여 연삭 숫돌로 그라인딩을 한 후 금속재 브러쉬로 브러슁하는 등의 방법으로 둥글게 만들어 준다. 이와같이 둥글게 형성한 기재(7)의 단부(8)는 서로 맞대어 놓은 상태에서 덮판(9)을 덮은 후 덮판(9)과 기재(7)를 용접함에 의해서 서로 연결된다.4 is a cross-sectional view of the reinforcing band of the explosion-proof reinforced cathode ray tube according to the present invention. Reference numeral 7 is a substrate constituting the reinforcing band of the explosion-proof reinforced cathode ray tube. The end 8 of the above-mentioned base material 7 is cut and ground by grinding with a grinding wheel after grinding with a grinding wheel. The end portions 8 of the substrate 7 rounded in this way are connected to each other by welding the cover plate 9 and the substrate 7 after covering the cover plate 9 in a state in which they face each other.
