Abstract

컬러 TV, 컴퓨터등의 브라운관에는 전자총으로부터 방출되는 R(빨강색), G(녹색), B(검정색)의 3가지 전자빔의 운동량을 미세조정하는 역할을 하는 콘버어젠스 퓨리티 마그네트(convergence purity magnet)가 전자총의 입구에 부착되어 있다. 콘버어젠스 퓨리티 마그네트는 보통 수십 가우스(gauss)의 크기를 갖는 2극, 4극, 6극의 링형태의 영구자석 조합으로 구성되어 있으며, 이들의 위치를 회전시키므로써, 전자빔의 운동방향을 미세조정한다. 콘버어젠스 퓨리티 마그네트는 수십개씩 적층시킨후 다극착자를 행하여 대량생산되고 있으나, 착자후 착자요오크의 길이방향에 따라 마그네트의 표면자속밀도의 크기가 불균일하고, 요오크 극간 폭이 큰 경우는 극간의 표면 자속 밀도 분포 왜곡현상이 발생하는 문제점이 있다. 따라서, 본 발명에서는 요오크의 단부에 존재하는 리턴코일의 형상과 그외 부분의 코일위치를 결정하여, 이와 같은 문제점을 해결하므로써, 품질의 균일화와 콘버어젠스 퓨리티 마그네트의 기능을 향상시켰다.In tube tubes such as color TVs and computers, a convergence purity magnet is used to fine-tune the momentum of three electron beams, R (red), G (green), and B (black). Is attached to the inlet of the electron gun. The Convergence Purity Magnet is composed of a combination of two-pole, four-pole and six-pole ring-shaped permanent magnets, usually of several tens of Gauss size, and by rotating their positions, the direction of movement of the electron beam is fine. Adjust Convergence purity magnets are mass-produced by stacking dozens of multi-pole magnetizers.However, the surface magnetic flux density of magnets is uneven along the longitudinal direction of the magnetizing yoke after magnetizing, and the gap between the yoke poles is large. Surface magnetic flux density distribution distortion occurs. Therefore, in the present invention, the shape of the return coil present at the end of the yoke and the coil position of the other portion are determined, thereby solving the above problems, thereby improving the uniformity of quality and the function of the convergence purity magnet.
