본 고안은 음극선관용 전자총 구체에 관한 것으로서, 특히 타원 대구경 전자총의 주렌즈부를 구성하는 외주전극의 형상을 개선하여 극판의 후퇴량을 일정하게 하고 용접위치를 변경하여 용접작업성을 향상시키는데 적합하도록 한 것이다.The present invention relates to an electron gun sphere for a cathode ray tube, in particular to improve the shape of the outer electrode constituting the main lens portion of the elliptical large-diameter electron gun to uniformly retreat the pole plate and to change the welding position to improve the welding workability will be.
일반적으로 포커스 특성에 영향을 주는 요인의 하나로 전자총의 주렌즈 구경이 있는데 양호한 포커스 특성을 얻을려면 주렌즈 구경이 큰 것이 바람직하다.In general, one of the factors affecting the focus characteristics is the main lens aperture of the electron gun. In order to obtain good focus characteristics, the main lens aperture is preferably large.
그러나 인라인형 전자총에서는 제1도에서와 같이 적,녹,청의 3색 각각에 대응하는 3개의 전자총을 동일 수평면에 배열하여 일체화 되어 있으므로, 내경이 한정된 네트관 내에 전자총을 수용하면 각 전자총의 주렌즈를 구성하는 원통의 구경 및 주렌즈 간격을 취할 수 있는 치수는 크게 제약을 받게 되어 주렌즈 구경을 증대하고자 하는 요구를 충족시키지 못하였다.However, in the inline type gun, as shown in Fig. 1, three electron guns corresponding to each of the three colors of red, green, and blue are arranged in the same horizontal plane so that when the electron gun is accommodated in a net tube having a limited inner diameter, the main lens of each gun is used. The diameters of the cylinders and the dimensions that can take the main lens spacing are greatly constrained and do not meet the demand for increasing the main lens diameter.
이를 해결하기 위한 종래의 개선방법으로서는 제2도에서와 같이 타원 대구경 전자총의 주렌즈부를 구성하였는데, 여기서 극판(12)(22)은 중앙비임에 대해서는 타원 개공(13)(23)을 가지고 있으나 양측 비임에 대해서는 타원개공이 절반으로 절단되어 좌우 양단부에서 외주전극(11)(21)과 접하는 부분이 제거되어 있다.As a conventional improvement method for solving this problem, as shown in FIG. 2, the main lens portion of the elliptical large-diameter electron gun is configured, wherein the pole plates 12 and 22 have elliptical openings 13 and 23 for the center beam. As for the beam, the elliptical opening is cut in half so that the portions in contact with the outer circumferential electrodes 11 and 21 at both ends are removed.
즉 중앙비임의 통로는 극판(12)(22)에 각각 형성된 개공(13)(23)에 의해서 둘러싸여 있으나 양측비임의 통로는 극판(12)(22)의 단부에 의해서 부분적으로 둘러싸이며 나머지부분은 외주전극(11)(21)에 의해서 둘러싸여져 있다.That is, the passage of the central beam is surrounded by the openings 13 and 23 formed in the pole plates 12 and 22, respectively, but the passages of both beams are partially surrounded by the ends of the pole plates 12 and 22, and the remaining portions are It is surrounded by outer circumferential electrodes 11 and 21.
이와같은 타원 대구경 전극의 조립방법은 제3도와 같이 용접용 조립지그(3)에 외주전극(11)(21) 및 극판(12)(22)을 끼우면 이때 극판(12)(22)의 후퇴량(d)은 조립지그(3)에 의해 결정되고, 이 상태에서 레이저 발생기에서 발생된 레이저 빔(1)을 렌즈(2)로 집속시켜서 외주전극과 극판을 용융하여 용접하게 된다.The method of assembling the elliptical large-diameter electrode is the retraction amount of the pole plates 12 and 22 when the outer electrodes 11, 21 and the pole plates 12 and 22 are inserted into the welding assembly jig 3 as shown in FIG. (d) is determined by the assembling jig 3, and in this state, the laser beam 1 generated by the laser generator is focused on the lens 2 to melt and weld the outer circumferential electrode and the electrode plate.
그러나 이와같은 조립방법은 극판(12)(22)과 외주전극(11)(21)의 선접촉이 이루어져 레이저빔(1)의 용접위치를 맞추기가 어려울 뿐만 아니라, 극판(12)(22)의 후퇴량(d)은 순전히 용접용 조립지그(3)에 의존하게 되어 다량의 용접지그가 필요함에 따라 제품간에 산포가 커지게 되고 그에 따라 정(正)콘버젼스 특성이 나빠지게 되었다.However, this assembly method is not only difficult to match the welding position of the laser beam 1 by the line contact between the pole plates 12, 22 and the outer circumferential electrodes 11, 21, but also of the pole plates 12, 22. The amount of retraction (d) is purely dependent on the welding assembly jig 3, so that a large amount of welding jig is required, resulting in a large dispersion between products, and thus a positive convergence characteristic is worsened.
본 고안은 상기의 문제점들을 개성하기 위해 안출한 것으로서 타원 대구경 주렌즈 전극의 외주전극에 극판과의 겹치기 용접이 가능하게 되고 극판의 후퇴량을 결정하게 한 절곡부를 형성시키는 것을 특징으로 한다.The present invention has been made to solve the above problems, it characterized in that the overlapping welding with the pole plate is possible on the outer circumference electrode of the elliptical large-diameter main lens electrode to form a bent portion to determine the amount of retreat of the pole plate.
제4도에서와 같이 본 고안은 타원 대구경 주렌즈 전극의 극판(12)(22)의 후퇴량(d)을 결정지우고 극판(12)(22)의 용접위치와의 겹치기 용접이 이루어지도록 외주전극(11)(21)의 측면일부를 절개하여 전극내부로 구부린 형태의 절곡부(14)를 형성하여 구성한다.As shown in FIG. 4, the present invention determines the amount of retreat d of the pole plates 12 and 22 of the elliptical large-diameter main lens electrode, and the outer electrode so that the overlap welding with the welding positions of the pole plates 12 and 22 is performed. A portion of the side surfaces of (11) and (21) is cut out to form a bent portion 14 bent into the electrode.
제5도에서와 같이 외주전극(11)(21)의 절곡부(14)에 의해 형성된 홈(15)에 극판(12)(22)이 끼워지는 형태로 조립되어 이와같이 구성되는 본 고안은 극판(12)(22)의 후퇴량(d)이 외주전극(11)(21)의 절곡부 높이(d1)에 따라 항상 일정하게 유지되며, 또한 외주전극(11)(21)의 절곡부(14)와 극판(12)(22)과의 면접촉이 이루어져 겹치기 용접이 가해지므로 용접위치의 결정도 훨씬 용이해질 뿐만 아니라 보다 확실한 용접강도를 유지할 수가 있게 된다.As shown in FIG. 5, the present invention is constructed in such a way that the pole plates 12 and 22 are fitted into the groove 15 formed by the bent portion 14 of the outer circumferential electrodes 11 and 21. 12) The retraction amount d of the 22 is always kept constant according to the bend height d1 of the outer electrode 11, 21, and the bent portion 14 of the outer electrode 11, 21. Since the surface contact with the pole plates 12 and 22 is applied, the overlap welding is applied, so that the determination of the welding position is much easier and the more reliable welding strength can be maintained.
이상에서와 같이 본 고안은 외주전극(11)(21)의 절곡부(14)와 극판(12)(22)이 면접촉 되므로써 용이하게 용접위치를 변경하여 용접작업성을 향상시킬 수 있는 유용한 고안인 것이다.As described above, the present invention is useful to improve the welding workability by easily changing the welding position by the surface contact between the bent portion 14 and the pole plates 12 and 22 of the outer electrodes 11 and 21. It is
