Abstract

PURPOSE:To reduce the rotational component of the restoring force of a frame causing the generation of wrinkles when a metal mask is suspended. CONSTITUTION:A pair of elastic arm sections 4, 5 connecting a pair of mating elastic frame sides 2, 3 are branched in the middle, and they are jointed with the elastic frame sides 2, 3 at six or more positions. When a frame is compressed, the magnitude of the rotational component of the restoring force centering on the joint positions can be reduced.

Tension is constantly applied to each strip 11 so as to cancel thermal expansion even if the electron beam impinges upon the temperature rise of the color cathode ray tube during operation. In order to give tension to each strip 11, a compressive force is applied from the outside of the elastic frame sides 2 and 3 of the frame 1 to compress it, and the metal mask plate 1 is kept in this state.
0 is fixed to the elastic frame sides 2 and 3, and then the compressive force is removed. At this time, the tension applied to each strip 11 must be substantially uniform, so that when a compressive force is applied to the frame 1, the frame 1 is stretched in the longitudinal direction of the strip 11 of the metal mask plate 10. It is desirable to have a uniform restoring force only.

In the conventional stretchable color selection electrode of the color cathode-ray tube, since the elastic frame side of the frame and the elastic arm portion are only joined at four points, the difference between the maximum M max and the minimum M min of the rotational component of the restoring force is different. large. As a result, when the metal mask plate is fixed to the frame and the compressive force is removed from the frame, wrinkling occurs in the metal mask plate due to the concentration of the force perpendicular to the length direction of the strip due to the rotational component of the restoring force from the frame. There was a point.
