  • Method for engaging support studs into shadow mask spring apparatus
    Patent number: 4604072
    Abstract: A CRT has a spring for mounting the shadow mask assembly of the CRT onto a stud of the CRT panel. The spring has a circular flange contered on a stud receiving hole. Thus the stud hole is always straight up and at a fixed distance from a locator of an insertion machine regardless of any tilt of the spring, and therefore the shadow mask assembly is always correctly inserted into the panel.
