Abstract
A receptacle connector (10) has a plurality of plug-receiving cavities (24) defined along major sides by either outer major walls (36,38) of the receptacle hood (20) or by lengths of polarizing walls (28) parallel thereto, and along minor sides or ends thereof by minor walls (42) of the hood (20). Individual plug connector modules (100) such as single-row modules (100) receivable into the cavities (24) each include along one major side (124) thereof an elongate polarizing recess (128) to receive a polarizing wall (28). One outer major wall (38) of the hood (20) includes an elongate inward boss (44) shaped to act as a polarizing wall portion (144) from an end module, and the plug connector modules (100) when ganged together (210) will enter the receptacle section defined by the hood (20) only when in a proper polarized orientation. Key members (50) at each end of each cavity (24) correspond to key members (50 ) at each end of each plug connector module (100) to permit mating of a module (100) in the cavity (24) only when the opposing keys (50,50) are in proper keying relationship to each other. The polarizing and keying system practically eliminates mating of ganged plug connector m…
