Abstract
A method and apparatus for securing a deflection yoke onto a cathode ray tube includes forming pockets having deformable, resilient inner walls along a circumferential surface of the deflection yoke. When the deflection yoke is mounted on the cathode ray tube, the inner walls deform slightly to conform to a contact portion of the cathode ray tube. The position of the deflection yoke with respect to the cathode ray tube it then adjusted into proper alignment. Once the deflection yoke and cathode ray tube are properly aligned, fast curing epoxy is poured into each of the plastic pockets, wedging the deflection yoke permanently into its desired orientation on the cathode ray tube. The pockets can either be integrally formed with the deflection yoke or they can be manufactured and attached to the deflection yoke in a separate operation.
