Quick connect collet retainer with self-centering structure

摘要

A collet quick connect fluid coupling includes a self-centering structure that is received within a channel ( 36 ) in a pilot ( 32 ). The channel and self-centering leg ( 28 ) ensures the collet ( 26 ) is approximately centered within the housing ( 22 ) as a tube ( 38 ) is moved into the housing. This prevents misalignment of the collet relative to the tube ( 38 ). In a preferred embodiment, the collet ( 26 ) has a ramp ( 30 ) on an inwardly facing surface that cams along a surface on the pilot ( 32 ), assisting the collet ( 26 ) in expanding when a tube ( 38 ) is moved into a housing ( 22 ).
