TENSION MASK FRAME ASSEMBLY FOR COLOR CATHODE RAY TUBE

摘要

PURPOSE: A tension mask frame assembly is provided to reduce vibrations of tension mask by winding a wire or mounting a reinforcement member on the support body interconnecting first and second support members. CONSTITUTION: A tension mask frame assembly(100) comprises a frame(120) including a first support member(121) and a second support member(122) spaced apart from each other and a first strength member(123) and a second strength member(124) interposed between the first and second support members so as to support the first and second members; a tension mask(110) mounted to apply tension forces to the first and second support members, wherein the mask has a plurality of electron beam passing holes; a support body(130) having both ends fixed to the ends of the first and second support members in such a manner that the support body prevents a deformation of the tension mask caused due to the difference of thermal expansion between the support body and the first and second strength members and the first and second support members; and a vibration damping member(200) which is wound on the support body or fixes the support body so as to damp vibrations of the support body.
