본 고안은 인라인형 전자총에 관련된 것으로서 특히 비드그라스와 네크부사이의 방전형상을 제거하여 내전압 특성을 향상시키기 위한 비드그라스의 구조에 관한 것이다.The present invention relates to an inline electron gun, and more particularly, to a structure of bead glass for improving the breakdown voltage characteristics by removing the discharge shape between the bead glass and the neck portion.
종래의 인라인형 전자총에서는, 제1도에 도시된 바와 같이, G1전극(4), G2전극(5), G3전극(6) 및 G4전극(7)이 단일체로 이루어진 비드그라스(BEAD GLASS, 1)에 음극(3)과 일정간격을 유지한채로 융착 고정되었다.In the conventional inline electron gun, as shown in FIG. 1, the beadgrass G 1 electrode 4, G 2 electrode 5, G 3 electrode 6 and G 4 electrode 7 are formed in a single body. BEAD GLASS, 1) was fused and fixed while maintaining a constant distance from the cathode (3).
그러므로 인라인형으로 배열된 3개의 음극(3)에서 히터(2)의 가열에 의해 전자를 방출하면, 제어전극인 G1전극(4)에서 방출된 전자를 제어하고, 가솔전극인 G2전극(5)에서 전자를 가속시켰다.Therefore, when electrons are emitted by the heating of the heater 2 from the three cathodes 3 arranged inline, the electrons emitted from the control electrode G 1 electrode 4 are controlled and the G 2 electrode serving as a gasoline electrode ( In 5) the electrons were accelerated.
그리고, G1전극(4) 및 G2전극(5)을 통과한 전자는 주렌즈 형성 전극인 G3전극(6)과 G4전극(7)에서 주렌즈부를 통과한 후 실드컵부(SHIELD CUP, 8)를 통과하여 형광면을 발광시켰다.The electrons passing through the G 1 electrode 4 and the G 2 electrode 5 pass through the main lens part at the G 3 electrode 6 and the G 4 electrode 7 which are the main lens forming electrodes, and then the shield cup part (SHIELD CUP). , 8) and the fluorescent surface was emitted.
상기 전자의 이동과정중에서 전자가 주렌즈를 통과하기 위해서는 G3전극(6)과 G4전극(7)에 서로다른 전압이 인가되는데 G4전극(7)에는 도전피막(13)에 의해 도전된 약 20∼25KV의 고정압이 인가되고, G3전극(6)에는 약 4.5∼6.5KV 정도의 중간전압이 인가되었다.In a moving process of the electrons e is conductive in order to pass through the main lens is a different voltage to G 3 electrode 6 and G 4 electrode 7, there is G 4 electrode 7 is provided by a conductive coating (13) A fixed voltage of about 20 to 25 KV was applied, and an intermediate voltage of about 4.5 to 6.5 KV was applied to the G 3 electrode 6.
종래의 인라인형 전자총에서는 이와같이 G3전극(6)과 G4전극(7)사이에 현격한 전압차가 일어나 비드그라스(1)와 네크부(9)사이에 방전현상이 발생하거나 네크부(9)의 내벽에 있는 이물질에 의해서 방전이 발생하므로써 음극(3)에서 방출된 전자가 형광면상에 도달하는 과정중에서 방전현상에 의해 전자의 진행이 나쁜영향을 받아 STC DRIFT, 컨버전스(CONVERGENCE)등의 특성에 나쁜 영향을 미치고, 음극선관의 불량율이 높아지는 문제점이 있었다.In the conventional in-line type electron gun, a sharp voltage difference occurs between the G 3 electrode 6 and the G 4 electrode 7 so that a discharge phenomenon occurs between the bead glass 1 and the neck portion 9 or the neck portion 9. As the discharge is caused by foreign matter on the inner wall of the electrons, the electrons emitted from the cathode 3 reach the fluorescent surface, and the progress of the electrons is adversely affected by the discharge phenomenon. Therefore, the characteristics of STC DRIFT, CONVERGENCE, It had a bad effect, there was a problem that the failure rate of the cathode ray tube is increased.
따라서 본 고안은 현격한 전압차가 일어나는 음극선관에서 내전압의 특성을 개선시킬 수 있는 비드그라스의 구조를 제공함에 그 목적이 있다.Therefore, an object of the present invention is to provide a structure of bead glass that can improve the characteristics of the withstand voltage in the cathode ray tube in which a significant voltage difference occurs.
본 고안은 이를 위하여 단일체인 비드그라스를 복수개로 분리시키고, 분리된 각각의 비드그라스편을 금속판으로 연결하며, 금속판에 리드선(11)을 연결하여 하나의 일관된 비드그라스를 형성함으로써 불필요한 전자가 상기 금속판에 모이도록한 후 리드선(11)에 의해 음극등이 있는 쪽으로 내려가도록 하여 특성상 나쁜 영향을 미치지 않도록 한 것으로서 이를 첨부한 도면에 도시된 본 고안의 실시예에 따라 상술하면 다음과 같다.The present invention separates a plurality of single bead glass for this purpose, connects each of the separated bead glass pieces with a metal plate, and by connecting the lead wire 11 to the metal plate to form a single consistent bead glass by unnecessary electrons to the metal plate After gathering in the lead wire 11 to be lowered to the negative light is to have a negative effect on the characteristics as described in accordance with an embodiment of the present invention shown in the accompanying drawings as follows.
네크부(9)의 내부는 약 10-7Torr의 진공상태를 유지시키고, 네크부(9)의 확대되는 부분에는 고정압이 인가되는 도전피막(13)을 도포한다.The inside of the neck portion 9 maintains a vacuum of about 10 −7 Torr, and a conductive film 13 to which a fixed pressure is applied is applied to the enlarged portion of the neck portion 9.
여러전극이 융착 고정되는 비드그라스는 2개의 비드그라스편(12, 14)으로 분리하고, 분리된 양 비드그라스편(12, 14)은 금속판(10)으로 연결한다.The bead glass, in which several electrodes are fused and fixed, is separated into two bead glass pieces 12 and 14, and the separated bead glass pieces 12 and 14 are connected to the metal plate 10.
또한 양 비드그라스편(12, 14)중에서 하나의 비드그라스편(14)에는 상호 마주보도록 위치하여 주렌즈부를 형성하는 G4전극(7)과 G3전극(6)을 고정하되 G3전극(6)은 상기 비드그라스편(14)과 연결된 금속판(10) 및 다른쪽의 비드그라스(12)에도 고정한다.Also, one of the bead glass pieces 12 and 14 is fixed to one bead glass piece 14 so as to face each other and to fix the G 4 electrode 7 and the G 3 electrode 6 which form the main lens part, but the G 3 electrode ( 6) is also fixed to the metal plate 10 and the other bead glass 12 connected to the bead glass piece 14.
금속판(10)에는 리드선(11)을 연결하여 불필요한 전자가 금속판(10)에 모인후 음극(3)이 있는 쪽으로 이동할 수 있도록 한다.The lead wire 11 is connected to the metal plate 10 so that unnecessary electrons can be collected on the metal plate 10 and then moved toward the negative electrode 3.
그리고, 또 한편 비드그라스(12)에는 가속전극인 G2전극(5)과 제어전극인 G1전극(4)을 일정한 간격을 유지하는 상태로 고정함과 동시에 G1전극(4)의 하단부에는 연전자를 방사하는 음극(3)을 고정한다.On the other hand, the bead glass 12 is fixed to the G 2 electrode 5, which is an acceleration electrode, and the G 1 electrode 4, which is a control electrode, while maintaining a constant interval, and at the lower end of the G 1 electrode 4, The cathode 3 emitting the soft electrons is fixed.
그러므로, 음극(3)에서 전자가 방사되면 G4전극(7)에는 약 20∼25KV의 고압이 인가되고, G3전극(6)에는 약 4.5∼6.5KV 정도의 중간전압이 인가된다.Therefore, when electrons are emitted from the cathode 3, a high voltage of about 20 to 25 KV is applied to the G 4 electrode 7, and an intermediate voltage of about 4.5 to 6.5 KV is applied to the G 3 electrode 6.
그리고, 상기와 같이 현격한 전압치에 의해 G3전극(6)에서 불필요한 전자가 발생하나 이러한 불필요한 전자는 금속판(10)에 모이게 되고, 이어서 리드선(11)에 의해 음극(3)이 있는 쪽으로 이동하게 되어, 네크부(9)의 내벽과 각 전극사이 사이에서 방전현상이 발생하지 않게 된다.As described above, unnecessary electrons are generated at the G 3 electrode 6 due to the sharp voltage value, but these unnecessary electrons are collected on the metal plate 10, and then the lead wire 11 is moved toward the cathode 3. As a result, a discharge phenomenon does not occur between the inner wall of the neck portion 9 and each electrode.
이와 같이 본 고안은 비드그라스를 복수개의 비드그라스편으로 분리한 후 개개의 비드그라스편을 금속판으로 연결하여 사용하므로써 G3전극과 G4전극 사이의 현저한 전압차에 의해 발생하는 불필요한 전자를 모아 흡수함으로써 네크부내벽과 각각의 전극사이에 발생하는 방전현상을 방지하여 내전압의 특성을 향상시키는 작용효과가 있다.As such, the present invention separates bead glass into a plurality of bead glass pieces, and then connects the individual bead glass pieces with a metal plate to collect and absorb unnecessary electrons generated by the remarkable voltage difference between the G 3 electrode and the G 4 electrode. As a result, there is an effect of preventing discharge from occurring between the neck portion inner wall and each electrode, thereby improving the characteristics of the withstand voltage.
