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.

Protective means for CRT base

Structural means are provided in an electron tube base for expeditiously controlling the flow of dielectric adhesive material relative to designated lead positions therein. This is accomplished by barrier means in the form of a centralized rim, extending from the crown portion of the base, which isolates the low voltage leads from the flow of dielectric material. In conjunction therewith, a trough-like channel is formed in the floor of the base flange to expedite flow of the dielectric material from the central cavity of the base to the vicinity of the high voltage leads.
