ABSTRACT:
The invention provides a one-piece protective cap, discretely formed of semi-rigid material, which encloses the major area of a CRT base. The cap, which maintains alignment of the connector pins of the tube, completely shields the vulnerable areas of the base from possible contamination, and thereby prevents the possible development of resultant leakage and arcing thereacross. The cap is retained on the base by the utilization of a plurality of spatially-related nubbins in the cap interacting with the sidewall of the base to provide a plurality of pressured retention areas.
