Abstract
A mask frame damper has a vibration absorbing member installed between a mask frame and a stud pin formed in a panel of a CRT. This member has a mounting part to be fixed on a frame and a first and a second absorption part extending therefrom and each bent at a predetermined angle. A bending joint formed between the first and second absorption part is in contact with a stud pin and the end of the second absorption part is in contact with the mounting part. Balls are installed at the first and second absorption parts. The first and second vibration absorption parts, in one embodiment, are formed by a plate spring with balls having a predetermined weight installed therein.
Claims16
In a cathode ray tube having an electron gun, a display panel receiving electrons from the gun, a shadow mask, a mask frame for supporting the shadow mask, and means for fixing the mask frame in position with respect to the panel, including a first mounting element fixed to the panel and a second mounting element extending from the mask frame, the improvement wherein damping means for absorbing vibrations is disposed between the mask frame and the first mounting element, wherein the damping means comprises an elongate element including a base fixed to the mask frame, a first shock absorption part extending from the base, a second shock absorption part extending from the first shock absorption part, and a first ball and a second ball installed on the first and second absorption parts, respectively.
A damping element for minimizing vibrations between a display panel and a mask frame attached to the panel for supporting a shadow mask in position with respect to the panel, the damping element comprising a vibration-absorbing member fixed to the mask frame and in contact with a mounting element fixed to the panel for attaching the mask frame to the panel, wherein the vibration-absorbing member comprises an elongate member having a base fixed to the frame, a first absorption part extending from the base, a second absorption part extending from the first absorption part, and first and second balls installed on the first and second absorption parts, respectively.
