A tension mask frame assembly for a CRT

摘要

A tension mask frame assembly (24) for a color cathode-ray-tube (10) comprising a frame (48) having four respective sides, two of the sides paralleling each other and having insert receiving brackets (56) for supporting strand termination inserts (58) therein and vertical mask strands (44) welded to said termination inserts. The strands have a plurality of cross-wires (46) extending perpendicular to the strands and attached thereto by a conductive bonding material (50). The wires and termination inserts are composed of materials having a first coefficient of thermal expansion. The frame and receiving brackets are composed of materials having a second coefficient of thermal expansion. The termination inserts thermally expand and contract independently of the frame and receiving brackets, whereby movement of the strands in the horizontal dimension is controlled by thermal expansion and contraction of the termination inserts and cross-wires. <IMAGE>
