ABSTRACT OF THE DISCLOSURE This disclosure depicts and describes a unitized, in-line electron gun for television cathode ray tubes having a bead-type structure for mechanically supporting, spacing, aligning and electrically isolating gun components. This disclosure is particularly directed to an improved system of electrode support that absorbs stress induced during the mounting process to leave the gun structure substantially free of residual stress, thus reducing the incidence of bead fracture and electrode displacement. The electrodes are supported as a coherent unit in spaced tandem succession along the gun's central axis by electrode support tabs extending from each electrode with the support tabs embedded in two elongated, axially oriented structural beads positioned on opposite sides of the electrodes The tabs on one of the electrodes comprise on each side thereof a pair of tabs spaced transversely to the gun's central axis. The support tabs have a distal end and a stress-absorbing section, the distal end of each of the tabs being embedded in one of said structural beads, with the stress-absorbing section at most partially embedded in the structural bead. The stress-absorbing section is of such composition, shape and dimension as to deflect beyond its elastic limit during embedment of the tab in the structural bead and to thereby yield and set permanently in a deformed but supportive attitude substantially free of any residual stress.
