Shroud-to-board polarization and keying system

摘要

An alignment and blind mate assist shroud (22) having a body section securable to a connector housing (24) has a protrusion (150) adapted to extend beyond the mounting face (48,50) of the connector housing (24) to key the connector assembly (62) to a particular one of several possible assembly receiving locations on the circuit board (154) on which the assembly (62) is mounted. The polarization protrusion (150) cooperates with an aperture (152) in the circuit board (154) on which the connector assembly (62) is adapted to be mounted to assure that the appropriate connector assembly (62) is mounted at the corresponding location on the circuit board. The polarization protrusion may be provided at any one of several locations to also provide a connector assembly to board keying function.
