Abstract

본 발명은 칼라 음극선관용 전자총에 관한 것으로 특히 집속전극의 길이를 정확하게 유지할 수 있도록 이를 형성하는 전극간의 정확하게 할 수 있도록 하기 위하여,The present invention relates to an electron gun for a color cathode ray tube, in order to be able to precisely inter-electrode forming it to maintain the length of the focusing electrode,

집속전극을 구성하는 캡형상부와 컵형상부중 한 전극은 전자빔 공통공에서 인라인방향과 평행한 부분의 일부분을 관축방향으로 일정 길이만큼 연장하고, 그 연장된 부분의 끝부분은 비드글래스가 용접가능하도록 넥크쪽으로 꺾으며, 나머지 한 전극은 공통공에서 인라인방향과 평행한 부분의 일부분을 관축방향으로 일정 길이만큼 연장하고 집속전극을 구성하는 캡형상부와 컵형상부중 한 전극은 전자빔 진행방향에 수직되는 면에 상기의 전극이 관통할 수 있는 적어도 두쌍의 구멍을 구비하였다.One of the cap-shaped portion and the cup-shaped portion constituting the focusing electrode extends a portion of the portion parallel to the in-line direction in the electron beam common hole by a predetermined length in the tube axis direction, and the end portion of the extended portion allows the bead glass to be welded. One electrode of the cap-shaped portion and the cup-shaped portion constituting the focusing electrode extends a part of the portion parallel to the inline direction in the common direction in the tube axis direction, and the other electrode is perpendicular to the electron beam traveling direction. At least two pairs of holes were provided in which the electrode can penetrate.
