Abstract

본 발명은 브라운관 전극부품의 신규한 제조방법을 개시한다.The present invention discloses a novel method for producing CRT electrode components.

인라인형 칼라 전자총의 전극부품에는 측벽효과의 차단을 위해 슬리이브를 형성하는데, 종래에는 이 슬리이브가 갈라지거나 축경되는 문제가 있었다.In the electrode part of the inline type electron gun, a sleeve is formed to block the sidewall effect, which has conventionally been a problem that the sleeve is cracked or reduced.

본 발명에서는 슬리이브를 다단계 성형, 특히 소요길이 보다 작은 깊이의 인입부를 성형한 뒤 다시 이 인입부로 슬리이브를 성형하도록 함으로써 종래의 문제점을 해결하였다.In the present invention, the conventional problem is solved by forming the sleeve in multiple stages, in particular, forming an inlet having a depth smaller than the required length, and then molding the sleeve into the inlet.
