An electrical connector is made repairable by providing a front insert (16) which is removable from and retained in the shell by an O-ring. The shell includes an undercut (34) in which the O-ring is mounted, and the insert includes a circumferential elliptical groove (31). In use, as the insert assembly is inserted into the shell, the O-ring mounted on the undercut of the shell is compressed by the insert until it reaches the groove, whereupon it expands into the groove in a direction parallel to the direction of insertion, which constitutes the major axis of the elliptical profile of the groove, and thus provides positive retention and sealing without the need for additional retention mechanisms. Removal is facilitated by a removal tool which includes hooks extending from a front circumference of a sleeve of the removal tool. The hooks are inserted through slots (26) in the insert and past a collar (29) provided around the mating interface (17) of the insert. The tool is then rotated a short distance to cause the hooks to engage a back surface of the collar, while a piston provides a biaising force to lock the insert against the connector during removal. <IMAGE> |
