A phone plug (10) for substantially noiseless electrical engagement with a phone jack (50) having a neck (52) includes a tip assembly (20), a stem assembly (30), and a terminal assembly (40), all disposed coaxially along a longitudinal axis (15). Stem assembly (30) includes a sleeve (31), a base (32) having a cavity (33) formed in the end thereof flared into sleeve (31), a substantially cylindrical, movable collar (34) having an annular shaped flange (35) formed at one end thereof, and a biasing coil spring (36). Coil spring (36) is placed coaxially over sleeve (31) with one of its ends seated within cavity (33). Movable collar (34) is placed coaxially over sleeve (31) with flange (35) in contact with the end of coil spring (36) opposite that seated within cavity (33). Coil spring (36) acts against one side of flange (35) to bias movable collar (34) into electrical engagement with tip assembly (20). When phone plug (10) is fully seated in phone jack (50), neck (52) acts against the other side of flange (35) to overcome the bias and electrically disengage movable collar (34) from tip assembly (20). |
