ABSTRACT:
A color cathode ray tube shadow mask assembly includes a panel having a screen; a shadow mask positioned within the panel; a frame supporting the shadow mask; and a self-compensating hook spring which is fixed to the frame within the panel, suspending the shadow mask assembly within the panel, the hook spring including a fixed planar portion welded to the frame, a coupling part for receiving a stud pin, and a connecting part connecting the coupling part with the fixed planar portion, wherein the distance between the planar portion and the coupling part increases with the distance from the connecting part whereby the fixed planar portion of the hook spring welded to the frame is inclined at a predetermined angle relative to the coupling part. The bending portion between the connecting part and the fixed planar portion is plastically deformed with a smaller force and the angle between the connecting part and the planar portion is smaller than in the conventional hook spring so that the resilience at the bend is not decreased so much. Through the resilience at the bend, the shadow mask frame assembly is flexibly and resiliently supported and the hook spring withstands vibrations better.
