CRT Pin alignment means

Claim 1

In a cathode ray tube-base combination wherein a substantially annular array of tube connector pins exteriorly protrude through a plurality of apertures in the base member whereof at least one pin is isolated by traversing a base aperture encompassed by a spatially related tubular isolation structure integrally formed as part of said base member and having a length exceeding that of the isolated pin positioned therein, an improved removable insert means for assuring positive alignment of said isolated pin within said tubular structure comprising: a longitudinal body member formed of a non-rigid material for insertion into said tubular structure, said member having forward and rearward ends and a length at least approximating the depth of said isolation structure, said member evidencing a lateral configuration similar to the internal cross-section of said tubular structure and being dimensionally compatible to facilitate insertion thereinto; said body member having a longitudinal bore formed therein from the forward end thereof to receive and provide substantially contiguous encompassment of said isolated pin, the outer surface of said member having a compressible retentive protuberance formed thereon in a manner to make pressured contact with the inner wall surface of said tubular structure thereby providing an interference fit when said insert is positioned therein, said member having a substantially central longitudinal open-end cavity formed therein inward from said rearward end to promote degree of resiliency for said retentive protuberance.
