Abstract

본 발명은 칼라 음극선관용 전자총의 전극을 개시한다.The present invention discloses an electrode of an electron gun for a color cathode ray tube.

본 발명은 상호 소정의 간격을 세개의 전자빔 통과공이 인라인상으로 형성되며 상기 전자빔 통과공의 주위에 일측 방향으로 돌출된 비이드가 형성된 칼라 음극선관용 전자총의 전극에 관한 것으로, 상기 양측의 전자빔 통과공 가장자리에 형성된 양측의 비이드의 높이가 중앙부에 형성된 비이드의 높이보다 높게 형성된 것에 그 특징이 있으며, 이는 전극의 조립시 비이드부가 손상되어 내전압 특성이 저하되는 것을 방지할 수 있다.The present invention relates to an electrode of an electron gun for a color cathode ray tube, in which three electron beam through holes are formed in an inline shape at a predetermined distance from each other, and beads formed to protrude in one direction around the electron beam through holes are provided. The height of the bead on both sides formed at the edge is characterized by being formed higher than the height of the bead formed in the central portion, which can prevent the bead portion is damaged when assembling the electrode to prevent the withstand voltage characteristics from deteriorating.
