Abstract
Cathode-ray tube comprising a frame/colour selection mask assembly, in which the free end of the skirt of the mask is constrained by lugs integral with the frame, in such a way as to minimize the nuisance movements of the skirt of the mask under the influence of vibrations generated by the environment of the tube.
Claims5
Colour cathode-ray tube comprising:
- a substantially rectangular faceplate on the inner surface of which is deposited a luminescent screen, the said faceplate being practically perpendicular to the longitudinal axis Z of the tube,
- a colour selection mask disposed facing the luminescent screen, the said mask comprising a perforated surface substantially perpendicular to the longitudinal axis Z and a peripheral skirt bent in a direction substantially parallel to the longitudinal axis Z,
- a substantially rectangular frame comprising a pair of long sides and a pair of short sides, each side of the frame exhibiting a flange substantially parallel to the longitudinal axis Z, the peripheral skirt of the mask being welded to the said flange at several points
- wherein the frame comprises lugs disposed on the flange of the side in contact with the skirt of the mask, the said lugs at least partially overlapping the free end of the said skirt.
