ABSTRACT:
An electrical plug connector (2) for mating With a receptacle connector (4) mounted to float in a back panel (P2) of a drawer containing a power supply distribution module, comprises polarizing alignment members (68,78) arranged on opposite sides of a forward plug part (42) the connector (2). The polarizing alignment members (68,78) are offset from each other longitudinally of the plug part (42) and unsymmetrically with the longitudinal center of the plug part (42). The receptacle connector (4) has a hood (106) formed with opposite alignment member receiving arcs (136,138) which are offset unsymmetrically with respect to the longitudinal center of the hood (106) in such a way as to be capable of receiving the respective polarizing alignment members (68,78) of the plug connector (2). The plug connector (2) can be mounted to further panel (P1) which may be part of a fixed casing, and which has alignment member receiving recesses (95,96) complimentary with the polarizing alignment members (68,78) of the plug connector (2) and with the alignment member receiving arcs (136,138) of the receptacle connector (4). By virtue of its polarizing to the further panel (P1), the plug connector (2) can only be mounted to the casing in its correct orientation for mating with the receptacle connector (4).
