Abstract

Abstract A contact retention assembly for an electrical connector comprising a retention disc having a passage therethrough receiving an electrical contact. Radially resilient retention fingers integral with the disc have inwardly extending ribs which engage within an annular groove in the contact to retain the contact in the passage. A relatively rigid collar is mounted over the retention fingers in front of the disc to restrain the fingers against outward movement thereby locking the contact in place. The collar may be slidably removed to allow removal of the contact from the contact passage from the rear.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 227 words
A rear insertion front release electrical connector contact retention assembly comprising: an insulator having a passage therethough from a front face to a rear face thereof; a contact having a forward contact engaging end, a rear termination end for connection to a wire and an annular groove between said ends, said contact being mounted in said passage with said contact engaging end and groove forward of said front face; radially resilient contact retention means integral with said insulator extending forwardly from said front face adjacent to said passage, said retention means having an outer surface and a rib on the inner surface thereof engaged with said groove to limit axial movement of said contact in said passage in opposite directions; a relatively rigid support collar having an opening therein slidably receiving said retention means, the wall of said opening firmly engaging said outer surface of said retention means at least in the region surrounding said rib to provide a rigid support therefor restraining said retention means against radially outward movement thereof; and said collar being slidably removable in the forward direction from said retention means allowing said contact to be removed rearwardly from said passage; said retention means comprises a plurality of spaced fingers; and the wall of said opening in said collar embodies a plurality of spaced inwardly extending ridge members interleaved between said spaced fingers.
