Abstract
Abstract A contact pin having a collar is removably retained within a housing cavity by a retention bushing comprising a longitudinally split cylindrical sleeve encircling the connector terminal of the pin. The collar of the pin is held between a shoulder at the rear of the cavity and the rear end of the sleeve. The walls of the cavity radially compress the sleeve so as to retain the contact pin and the sleeve within the housing.

Total Claims: 4
Claim 1
Independent Claim
294 words
A connector assembly comprising: a contact pin including a collar portion and a shank portion for use as a connector terminal; a retention bushing comprising a radially resilient sleeve having an axial opening extending from one end to the other end of said sleeve, said shank portion extending through said opening; a housing having a cavity including a shoulder means abutting the side of said collar portion opposite said shank portion and cavity walls radially compressing said sleeve, said sleeve bearing against the other side of said collar portion, said sleeve and said collar portion being held in position by a retention force due to the radial load of the resilient sleeve factored by the coefficient of friction between said sleeve and said cavity walls; said housing has an opening between said cavity and the mating side of said housing with the connector terminal extending therethrough, said opening permitting insertion and removal of said sleeve and said collar portion therethrough without damage to the housing; said housing has another opening between said cavity and the rear side of said housing, said another opening substantially precluding insertion and removal of said sleeve and said collar portion therethrough; and said assembly further comprises a tubular feedthrough low pass filter concentrically disposed about a portion of said shank portion of said connector terminal, said filter being spaced from said collar portion by said retention bushing; and said housing, in addition to the sleeve receiving cavity section, further includes a filter receiving cavity section comprising said first mentioned opening, said filter receiving cavity section having a larger diameter than said sleeve receiving cavity section, said cavity walls between said sleeve receiving cavity section and said filter receiving cavity section being tapered inwardly toward said sleeve receiving cavity section.
