Abstract

본 발명은 칼라 음극선관용 새도우마스크 프레임 조립체를 개시한다.The present invention discloses a shadowmask frame assembly for a color cathode ray tube.

본발명은 패널의 내부에 고정설치되는 것으로 다수의 전자빔통과공이 형성된 유공뷰와 상기 유공부의 가장자리로 부터 소정길이 연정되며 비이드가 형성된 무공부와, 상기 무공부의 가장자리로 부터 직각 방향으로 절곡 형성된 스커트브를 가지는 새도우마스크와, 사기 새도우마스크의 스커트부와 결합되어 이를 지지하는 프레임, 을 구비하여 된 칼라 음극선관용 새도우마스크 프레임 조립체에 관한 것으로, 상기 비이드의 깊이가 0.8 내지 2.5mm의 범위 내에서 형성된 것에 그 특징이 있으며, 이는 새도우마스크의포밍시 전자빔통과공의 변형과 도밍현상을 극소화 할 수 있는 이점을 가진다.The present invention is fixedly installed in the interior of the panel is a hole length view from which the plurality of electron beam through hole is formed and the predetermined length is fixed from the edge of the hole and the bead is formed, and bent in a direction perpendicular to the edge of the non-hole A shadow mask frame assembly for a color cathode ray tube comprising a shadow mask having a skirt formed therein, and a frame coupled to and supporting a skirt portion of a fraudulent shadow mask, wherein the depth of the bead is in the range of 0.8 to 2.5 mm. It is characterized in that it is formed in the inside, which has the advantage of minimizing the deformation and the doming phenomenon of the electron beam through hole when forming the shadow mask.
