Abstract

본 발명은 칼라수상관용 전자총에 관한 것으로, 음극(20)에 대하여 일렬로 제어전극(21), 가속전극(22), 양극(24) 및 쉴드컵(25) 이 배열된다. 가속전극(22)과 양극(24)사이에 일정간격을 유지하는 제1전극(23A)과 제2전극(23B)으로 구성도는 4극자렌즈구성전극(23)이 배설되며 제1전극(23A)에 포커스정전압이, 2리그 제2전극(23B)에 포커스 다이아나믹 전압이 인가된다. 각 전극(23A)의 사각 개방부(26)(27)가 형성되고 제1전극(23A)의 사각개방부(26)에 수직측벽(28)이 형성되며 제2전극(23B)의 사각개방부(27)에 수평측벽(29)이 형성되어 이들 수직측벽(28)과 수평측벽(29)이 4극자렌즈를 구성한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electron gun for color water pipes, in which control electrodes 21, acceleration electrodes 22, anodes 24, and shield cups 25 are arranged in a row with respect to the cathode 20. The first electrode 23A and the second electrode 23B, which maintain a constant distance between the acceleration electrode 22 and the anode 24, are arranged in the quadrupole lens composition electrode 23 and the first electrode 23A. ), And a focus dynamic voltage is applied to the two-lead second electrode 23B. Square openings 26 and 27 of each electrode 23A are formed, and vertical side walls 28 are formed on the square opening 26 of the first electrode 23A, and the square openings of the second electrode 23B are formed. Horizontal side walls 29 are formed at 27 so that these vertical side walls 28 and the horizontal side walls 29 constitute a quadrupole lens.
