ABSTRACT:
An electrical connector assembly has a first and a second electrical connector. Each electrical connector includes a housing having electrical contacts therein wherein each contact of the first electrical connector mates or connects with a corresponding contact of the second electrical connector. A keying arrangement has keying surfaces for inhibiting the mating except for mating a first electrical connector to a designated second electrical connector. Another keying arrangement is provided by two pairs of electrical contact housings fitted within interior cavities of the first and second electrical connectors. Each electrical contact housing includes a key sized to slip fit into an opposing opening of an electrical contact housing fitted within an interior cavity of either the first or second electrical connector. Each key is arranged so that the first and second electrical connector housings will mate only when the four keys are in mating alignment with their respective opening.
