(57) An electrical connector member includes a cylindrical outer shell (1) which encloses
a bonded insulating insert assembly (2) having a plurality of axial passages (7) for
electrical contacts. The insert assembly includes a rigid main insert (3), a rigid
wafer (4), a rubber grommet (6) and a rubber seal (5). The shell has an internal shoulder
(8) which provides a stop for a collar (9) provided on the insert (3). A dish shaped
resilient beryllium copper retention ring (11) having a plurality of axially directed
slots (12) is placed in an internal annular recess (10) in the shell before the insert
assembly is inserted into the shell. When the insert assembly is inserted, the smaller
diameter edge (16) of the retention ring slides over the collar (9) until, on full
insertion, the edge (16) snaps firmly against the shoulder (14) of the collar. The
insert is then firmly supported in the shell by the spring force of the retention
ring and requires no encapsulation.
