Abstract

본 발명은 음극선관용 전자총 스템에 관한 것으로 특히 음극선관의 내부 진공도를 유지하기 위한 배기공정후의 진공도를 유지하도록 밀봉하는 공정인 스템의 배기관을 잘라내는 공정을 용이하게 하기 위하여 배기관에 잘라내는 부위에 비디부를 설치한 스템의 배기관에 관한 것으로써, 전자총을 음극선관의 내부에 내장, 고정시켜 주고 각 전기들에 일정전압을 인가해 주는 스템의 구조가 음극선관의 내부 진공도 유지를 배기시키는 통로인 배기관인 형상이 내측은 일직선 형태를 유지하면서 외측면에 비디부를 구비한 것이다.The present invention relates to an electron gun stem for a cathode ray tube, and in particular, to a cut portion in an exhaust pipe to facilitate a process of cutting an exhaust pipe of a stem, which is a process of sealing to maintain a vacuum degree after an exhaust process for maintaining an internal vacuum degree of the cathode ray tube. It is about the exhaust pipe of the stem with the part installed.The structure of the stem that embeds and fixes the electron gun inside the cathode ray tube and applies a constant voltage to each electricity is the exhaust pipe which is the passage through which the internal vacuum degree maintenance of the cathode ray tube is exhausted. The inner side of the shape is provided with a video portion on the outer side while maintaining the straight form.
