Color picture tube having improved shadow mask-frame assembly support

摘要

The improved color picture tube includes an evacuated glass envelope having a rectangular faceplate panel. The panel includes a shadow mask assembly mounted therein by support means located at the four corner of the panel. Each support means includes a stud attached to the glass envelope. The improvement comprises the support means also including, at each of the four corners, a first spring and a second spring. Each spring is elongated, with a first portion thereof attached to the mask assembly and a second portion thereof cantilevered away from the assembly. The first spring extends peripherally in a first direction with respect to the assembly, and the second spring extends peripherally in a second direction with respect to the assembly. The first spring includes an aperture within the second portion that engages a respective stud. A section of the second portion of the second spring overlaps the second portion of the first spring. The overlapped portions of the first and second springs are attached together.
