ABSTRACT:
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.
