Abstract

본 발명은 텔레비젼 수상기나 영상 표시기등에 사용되는 브라운관용 전자총에 관한 것으로서, 좀더 구제척으로는 전자비임을 발생시키는 캐소드와 제1그리드 사이의 간격을 일정하게 유지시킬수 있도록 한 것이다.The present invention relates to a CRT gun used for television receivers, video displays, and the like, and more specifically, to maintain a constant distance between a cathode and a first grid which generate an electron beam.

종래에는 정전용량이나 압력변화에 의해 캐소드와 제1그리드 사이의 간격을 유지시킨 상태에서 용접고정하였으므로 외부전하의 영향이나 기류 압력으로 인해 간격을 정확히 유지시키기가 곤란하였다.In the related art, welding is fixed while the gap between the cathode and the first grid is maintained by capacitance or pressure change, so it is difficult to accurately maintain the gap due to the influence of external charge or air flow pressure.

본 발명은 이를 개선하기 위해, 한개 또는 복수개의 전자비임을 스크린측으로 방출시켜 화상을 맺게하는 캐소드(11)와 제1그리드(14)사이를 절연지지체(15)로 일정간격 유지시킬수 있도록 하여서된 것이다.In order to improve this, the present invention is to maintain a predetermined interval between the cathode 11 and the first grid 14 to form an image by emitting one or a plurality of electron beams to the screen side with an insulating support (15). .
