Abstract

본 발명은 음극선관용 전자총 구체에 관한 것으로 특히 전극들이 절연지지체에 안정되게 고정되어 흔들림을 방지하여 열화를 방지하도록 한 것으로써, 전자빔을 발생시키는 음극과 제어전극과, 가속전극으로 구성되는 심극부와 전자빔을 가속, 접속하여 형광면에 맺히게 하는 제1가속/집속전극과 제2가속/집속전극과 제3가속/집속전극과 제4가속/집속전극으로 이루어진 주렌즈부로 구성된 인라인형 전자총의 전극중 하나 이상의 전극이 절연지지체와의 함몰부의 끝단부위에 삽입이 용이하도록 중앙공의 중심과 일치하는 부위에 절취부를 형성하고, 상기 절취부의 좌, 우측에 전극공과 평행한 수평방향으로 긴 횡장공을 형성하고, 절취부와 전극의 중앙공 사이에는 상기 횡장공(24)과 수직방향으로 긴 종장공을 형성한 전극으로 구성하였다.The present invention relates to an electron gun sphere for a cathode ray tube, and in particular, the electrodes are stably fixed to an insulating support to prevent shaking, thereby preventing deterioration. One of the electrodes of an inline type electron gun composed of a main lens portion consisting of a first acceleration / focusing electrode, a second acceleration / focusing electrode, a third acceleration / focusing electrode, and a fourth acceleration / focusing electrode for accelerating and connecting an electron beam to form a fluorescent surface. The above electrode forms a cutout at a portion coinciding with the center of the central hole so that the electrode is easily inserted into the end of the depression with the insulating support, and long horizontal holes are formed in the horizontal direction parallel to the electrode hole at the left and right sides of the cutout. The electrode was formed between the cutout and the center hole of the electrode by forming a long longitudinal hole in the vertical direction with the horizontal hole 24.
