Abstract
Abstract An electrical connector assembly (10) includes a female connector (12) and more than one male connectors (30) wherein the female connector (12) includes a first insulative housing (14) defining a plurality of cavities (16) for receiving a corresponding number of first contacts therein, respectively, and each of the male connectors (30) includes a second insulative housing (32) forming a plurality of sleeve members (34) thereof for accommodating a corresponding number of second contacts therein. The cavities (16) of the female connector (12) can receive the sleeve members (34) of the respective selected male connector (30) by means that a pair of keys (36) are formed on the two sleeve members (34) located at two opposite ends of the second housing (32) of each selected male connector (30), and a pair of fixed keyways (18) are respectively formed, adjacent to two cavities (16) at two opposite ends in the first housing (14) of the female connector (12), and at least one additional variable keyway (18) is formed, adjacent to one cavity (16), in the first housing (14) of the female connector (12) wherein such additional keyway (18) is positioned between such pair of fixed keyways (18). Therefore, the female connector (12) is adapted to receive not only one specific male connector (12) having the same number of sleeve members thereof corresponding to the cavities (16) of the female connector (12), but also at least one additional selective male connector (30) different from such specific male connector (30).
