Abstract
PURPOSE:To improve the vibration-resistance characteristic by coupling between the shadow mask of a color picture tube and the inner wall of a funnel through at least two kind of conductive springs thereby providing different natural frequencies. CONSTITUTION:The anode voltage of a color picture tube 1 is applied onto an anode button 11 provided on a funnel 4 then transmitted on a graphite film 12 on the inner face of the funnel and provided through at least two kind of conductive springs 14, 15 having different shape to a frame 7 while furthermore transmitted through a shadow mask 6, spring 8 and a pin 9 to an aluminium deposition film 10. Since the natural frequencies at the side of the shadow mask 6 and the inner wall 12 side of the funnel are made different, the high voltage from the anode button 11 can be transmitted continuously and reliably to the film 10 and the deterioration of the picture quality due to the vibration can be prevented.
