ABSTRACT:
In a shielded electrical connector assembly (2) for mating with a mating electrical connector (206) and including a connector receiving shell, a metal back shell (12 or 14) and an insulating cover (8 or 10) therefor, a coding key (18) has a keying part (184) projecting forwardly from the assembly and a keying abutment (190) which is of regular polygonal cross section. The abutment (190) is connected to the keying part (184) by means of a neck (189) to define a rib (106) which receives a flange (114) on the back shell (14) and a flange (42) on the connector receiving shell (6), the key (18) being thereby held against axial movement. The key (18) defines a through passage (194) for receiving a jack screw (16) with a mating end (202) thereof in the keying part (184). The shaft (199) of the jack screw is accommodated in recesses (164) in the back shell cover (19). A flat (192) of the abutment (190) engages a flat (182) in the cover (10) and a further flat (192) of the abutment (190) engages a side wall (76) of the back shell (14), so that the key (18) is retained in a predetermined angular orientation.
