  • Patent number: 4100453
    Abstract: An electron gun system constructed of three electron guns for a color television display tube comprises at least one electrode in each gun located alongside, and electrically connected to, the corresponding electrodes in the other guns. The electrodes are positioned with respect to each other by means of metal braces which are secured thereto and the free ends of which are secured in pairs in insulating supporting members. The electrical interconnection of at least one group of such electrodes is achieved by means of at least two contact springs which are each inserted between one pair of braces secured to adjacent electrodes in the group and to a common insulating member. The springs are inserted after assembly of the guns and are held in place by physical interference with the braces they engage.
