Electrical connector keying system

摘要

A keying system for an electrical connector arrangement includes a connector plug (18) having a housing (88) with a plurality of keying grooves (90) on at least one side thereof. A face plate (86) is mounted on the housing and includes at least one keying notch (92) in alignment with a respective one of the keying grooves (90). The other of the keying grooves are blocked by the face plate (86). A receptacle (26) is provided for receiving the connector plug (18). The receptacle includes a keying protrusion (48) for extending into the keying notch (92) and the respective one of the keying grooves (90). Therefore, the face plate (86) can be interchanged without changing the housing (88) to accommodate different arrays of keying protrusions (48) on the receptacle.
