ABSTRACT:
The invention relates to an improved one-piece electrode member for use in an in-line multi-beam cathode ray tube electron gun assembly. The improved electrode has a plurality of spaced apart in-line apertures individually oriented in cup-like depressions which are collectively encompassed by a configurated continuous rim forming a cup encompassing unitized portion within the member. Formed contiguously with each side of the unit is a substantially longitudinal rib embossment having at least one complementary rib projecting therefrom in an angular manner to extend through supporting projections of the electrode. The discretely located conjunctive embossing configurations of the member provide marked strengthening to the in-line structure.
