Abstract: An electrical connector assembly (1) includes an insulating housing (11), a number of mating ports (17), a first terminal group (12), a second terminal group (13) and a third terminal group (14). The insulating housing defines a number of receiving spaces (111) alternately arranged. A number of first, second and third slots (112,114,113) are respectively defined in the housing and communicate with corresponding cavities. The first terminal group comprises a plurality of terminal units each comprising a pair of contacting portions (124) exposed into the receiving spaces and a number of tail portions respectively received in the third slots. The second terminal group is received in the second slots. The third terminal group is received in the third slots and electrically connects with the tail portions of the first terminal group.
