An electrical connector assembly having a housing and a terminal alignment and protection plate. A mating surface of the housing has terminal alignment member receiving channels. The terminal alignment member receiving channels have first retention projections and second retention projections which extend into the terminal alignment member receiving channels. Rigid support members extend from a first surface of the terminal alignment and protection plate in a direction away from a second surface. The support members extend perpendicular to a planar portion of the terminal alignment and protection plate. The support members have flexible support beams which extend between the support members. The flexible support beams extend essentially parallel to the planar portion of the terminal alignment and protection plate.
