본 고안은 칼라수상관의 인라인형 전자총구체에 관한 것으로 특히 G1전극과 G2전극의 휘어짐을 방지하고 전극간 간격설정을 용이하도록하여 컷 오프(cut off)특성을 향상토록 한 칼라수상관의 전자총구체에 관한 것이다.The present invention relates to an inline type electron barrel of a color receiver, and in particular, an electron gun sphere of a color receiver to prevent the warpage of the G1 electrode and the G2 electrode and to easily set the gap between the electrodes. It is about.
일반적인 인라인형 전자총구체는 제1도와 같이 음극(2)과 히터(3)를 포함하는 음극부(1)와 G1전극(4), G2전극(5), G3전극(6), G4전극(7)간에 전자렌즈를 형성하는데 상기 전극(4,5,6,7)은 3개의 전자빔에 대응하여 각각 3개씩의 전자빔통과공인 개공이 형성되어 있다.A general inline electron gun body has a cathode part 1 including a cathode 2 and a heater 3, a G1 electrode 4, a G2 electrode 5, a G3 electrode 6, and a G4 electrode 7 as shown in FIG. Electron lenses are formed between the electrodes 4, 5, 6, and 7, each of which has three electron beam through holes corresponding to three electron beams.
이러한 구조의 전자총은 G1전극(4)에서 G4전극(7) 및 음극부(1)의 서포터등을 지그에서 조립할때 상기 전극지지체(8)인 비드유리에 고정한 다음 제2도와 같이 스팬세트(span set)작업을 행하는데 주지된 바와 같이 G2전극(5)의 면을 기준으로 하여 노즐(9)을 전극내에 삽입한 후 고압의 에어를 이용하여 G2전극(5)과 음극(2)의 간격을 규정치에 설정하고 음극부(1)의 서포터에 음극(2)을 용접고정하여 조립한다.The electron gun of this structure is fixed to the bead glass which is the electrode support 8 when assembling the supporter of the G4 electrode 7 and the cathode portion 1 from the G1 electrode 4 to the jig, and then a span set as shown in FIG. As is well known in the art, the nozzle 9 is inserted into the electrode with respect to the surface of the G2 electrode 5, and then the gap between the G2 electrode 5 and the cathode 2 is adjusted using high pressure air. It is set to the prescribed value and assembled by welding and fixing the cathode 2 to the supporter of the cathode 1.
여기서 G1, G2전극(4,5)은 제3a,b도에 도시한 것과 같이 판상구조물로 되어 있고 공지와 같이 각각 전자빔통과공인 개공(4R,4G,4B), (5R,5G,5B)이 형성되어 있으며, 제3도에서와 같이 종래의 판상구조로된 그리드전극은 평탄도가 나쁘게 되고 이 때문에 전극조립시 각 전극간 간격을 규정치에 맞게 설정하기가 곤란하였다.Here, the G1 and G2 electrodes 4 and 5 have a plate-like structure as shown in Figs. 3a and b, and the openings 4R, 4G, 4B, and 5R, 5G, 5B, which are electron beam through holes, respectively, are known as As shown in FIG. 3, the grid electrodes having a conventional plate-like structure have poor flatness, and thus, it is difficult to set the spacing between electrodes according to a prescribed value when assembling the electrodes.
즉 제4a,b,c,d도와 같이 G1, G2전극(4,5)의 양 끝단이 스페이서(10)로부터 떨어져 있거나 개공과 스페이서(10)가 서로 접촉되어 있어서 스페이서(10)를 전극으로부터 분리할때 상기 개공과 스페이서(10)의 마찰로 인해 G1, G2전극(4,5)의 변형이 발생되게 되어 이로인해 G2전극(5)과 음극(2)의 간격이 변동되게 되고 3개의 전자빔간의 컷 오프(cut off)조정이 곤란하게 되며 따라서 고품질의 관구조작이 용이하지 않게되어 전자총구체의 왜곡현상이 있게된다.That is, as shown in FIGS. 4a, b, c, and d, both ends of the G1 and G2 electrodes 4 and 5 are separated from the spacer 10 or the opening and the spacer 10 are in contact with each other to separate the spacer 10 from the electrode. At this time, the deformation of the G1 and G2 electrodes 4 and 5 occurs due to the friction between the openings and the spacers 10, which causes the gap between the G2 electrode 5 and the cathode 2 to fluctuate between the three electron beams. Cut-off adjustment is difficult, and therefore, high-quality tube structures are not easily produced, resulting in distortion of the electron muzzle.
본 고안은 상기의 문제를 해소코저 안출된 것으로 전극과 스페이서의 접촉이 전극의 양끝단부에서 이루어지게 하여 스페이서의 인출시 변형을 방지하고 전극의 평탄도 또한 계속유지케 된 것으로서, 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention solves the above problems, and the contact between the electrode and the spacer is made at both ends of the electrode to prevent deformation during extraction of the spacer and to maintain the flatness of the electrode as well. The explanation is as follows.
제5도는 본 고안의 구조를 나타낸 것인데 G1, G2 전극(4)(5)의 각 개공(4R,4G,4B), (5R,5G,5B)과 그 주변부를 스페이서를 중심으로 외향 돌설하는데 양외측개공 (4R,4B)(5R,5B)을 상기 중아의 개공(4G)(5G)보다 더 돌출되게 형성하였다.5 shows the structure of the present invention, and each opening (4R, 4G, 4B), (5R, 5G, 5B) and its periphery of the G1 and G2 electrodes (4) and (5) are turned outward with respect to the spacer. Outer openings 4R, 4B (5R, 5B) were formed to protrude more than the openings 4G (5G) of the middle-aged.
또한 G1, G2전극(4,5)의 양외측 개공(4R,4B), (5R,5B)과 그 주변의 돌출부는 각 중앙의 개공(4G)(5G)과 그 주변의 돌출부보다 크게 형성하여서 전극의 양 끝단부를 스페이서(10)에 접촉시켰다.In addition, the outer and outer openings 4R and 4B and 5R and 5B of the G1 and G2 electrodes 4 and 5 and the protrusions around them are formed larger than the openings 4G and 5G in the center and the protrusions around them. Both ends of the electrode were in contact with the spacer 10.
따라서 G1전극(4)과 G2전극(5)은 전극의 경사가 없는 양호한 형태를 가지고 전자빔의 통과공인 개공(4R,4G,4B), (5R,5G,5B)과 그 주변부가 스페이서(10)에 직접 접촉하고 있지 않기 때문에 스페이서(10)을 빼낼때 개공과 그 주변부에 어떠한 영향도 미치지 않으므로 전극의 변형을 방지하여 전극간 간격을 안정하게 설정할 수 있으므로 양 외측 전자빔에 관해서는 동일한 특성을 얻는것이 용이하다. 또한 중앙 전자빔이 통과하는 개공의 간격보다 양외측 개공의 간격이 넓게 되어 있어 음극과의 간격이 좁게 설정됨으로서 3개의 전자빔의 특성을 일치하는 것이 적당하다.Therefore, the G1 electrode 4 and the G2 electrode 5 have a good shape without the inclination of the electrode, and the openings 4R, 4G, 4B, 5R, 5G, 5B, which are the through holes of the electron beam, and the periphery thereof have the spacer 10. Since there is no direct contact with the opening and its periphery when the spacer 10 is pulled out because it is not in direct contact with, the gap between the electrodes can be set stably by preventing the deformation of the electrode. It is easy. In addition, since the distance between the outer and outer openings is wider than the gap between the openings through which the central electron beam passes, it is appropriate to match the characteristics of the three electron beams by setting the gap with the cathode narrow.
상기와 같은 구조에서는 전자빔의 통과공인 중앙측 개공과 양외측 개공은 서로 전극간 간격이 다르기 때문에 스팬세트작업에서 노즐(9)의 치수등을 설정하는데 보다 용이하며 판상 일체화된 전극을 대상으로 하는 캡형 일체화 전극에도 적용가능하여 제1도에 도시한 것과 같은 전자총의 구조에만 한정되지는 않는다.In the above structure, since the center opening and the outside opening of the electron beam are different from each other, the gap between the electrodes is different, so it is easier to set the dimensions of the nozzle 9 in the spanset operation, and the cap type for the plate-shaped integrated electrodes. Applicable to an integrated electrode, it is not limited only to the structure of the electron gun as shown in FIG.
이상과 같이 본 고안에 의하면 전극의 휘어짐의 발생과 변형 및 스페이서(10)에 의한 홈 발생 방지로 균일한 평탄도를 유지할 수 있고 전극간 간격 설정이 용이하게 되며 전극의 경사짐의 발생을 방지 할 수 있다.As described above, according to the present invention, it is possible to maintain uniform flatness and to easily set the spacing between the electrodes by preventing the occurrence of deformation and deformation of the electrode and the generation of grooves by the spacer 10. Can be.
상술한 바와 같이 본 고안은 G1전극(4)와 G2전극(5) 사이에서 스페이서(10)를 뺄때 3개의 전자빔이 통과하는 G1, G2전극(4,5)의 개공(4R,4G,4B), (5R,5G,5B)과 그 주변부가 스페이서(10)와의 접촉이 없고 G1, G2전극(4,5)의 양 끝단부만 상기 스페이서(10)에 접촉되므로 스페이서(10)의 인출로 인해 전극이 경사지게 될 염려가 없고 흠발생의 우려가 없게되며, 전극간의 간격설정이 용이하게 되고, 전극간의 간격변동이 생기지 않는다.As described above, according to the present invention, when the spacer 10 is pulled out between the G1 electrode 4 and the G2 electrode 5, the openings 4R, 4G and 4B of the G1 and G2 electrodes 4 and 5 through which three electron beams pass. , (5R, 5G, 5B) and its periphery have no contact with the spacer 10 and only the both ends of the G1 and G2 electrodes 4, 5 are in contact with the spacer 10 due to the withdrawal of the spacer 10. There is no fear that the electrodes will be inclined, there is no possibility of flaws, the spacing between the electrodes becomes easy, and the spacing between the electrodes does not occur.
또한 3개의 전자빔간의 컷 오프 특성의 조정이 용이하게 되고 각 전자빔에 있어서도 컷오프 변동이 발생하지 않는 효과가 있는 유용한 고안이다.In addition, it is a useful design that the adjustment of the cut-off characteristic between three electron beams becomes easy, and the cut-off fluctuation does not generate | occur | produce also in each electron beam.
