Abstract

본 발명은 음극선관의 후방에 설치되어 전자빔을 발사하는 전자총의 전극에서 주 렌즈역할을 하는 전극의 구성요소인 인너전극을 보다 용이하면서도 정밀하게 가공할 수 있도록 하므로서 포커스특성 및 OCV(Outer beam Convergence Value)특성이 향상되도록 한 전자총용 인너전극의 제조방법에 관한 것이다.The present invention allows the inner electrode, which is a component of the electrode serving as the main lens, to be easily and precisely processed in the electrode of the electron gun that emits the electron beam, which is installed at the rear of the cathode ray tube, so that the focus characteristic and the outer beam convergence value are increased. The present invention relates to a method for manufacturing an inner electrode for an electron gun in which the characteristics are improved.

이를 위해. 본발명은 프레스금형으로 인너전극(1)에 전자빔 통과공(1a)과 공간부(1b) 그리고 브릿지부(1c)를 동시 형성하도록 된 것에 있어서, 브릿지부(1c)의 두께가 감소되도록 상기 브릿지부를 인너전극의 성형과 동시에 단일금형에서 후가공하여 평탄화시키도록 된 것이다.for teeth. The present invention is a press mold to simultaneously form the electron beam through hole (1a), the space portion (1b) and the bridge portion (1c) in the inner electrode (1), the bridge portion (1c) so as to reduce the thickness of the bridge At the same time, the part is flattened by post-processing in a single mold at the same time as forming the inner electrode.
