Abstract
Abstract An electrical jack assembly for a modular telephone (10) utilizing the combination of a grommet (36), washer (38), and cap (40) to seal the jack opening (30) when a modular telephone cord plug (12) is inserted. The washer (38) includes a pair of projections (86, 88) which pass through slots (64, 66) in the grommet and enter slots (32, 34) within the jack frame (26), whereby the washer (38) and grommet (36) are keyed and prevented from turning. The cap (40) fits over the washer (38) and grommet (36) and couples with a threaded sleeve (28) on the jack frame (26).
