Abstract: A stacked electrical connector includes a front mating face, an insulative housing comprising and a plurality of contacts. The insulative housing has a first housing and a second housing arranged in an up-to-down direction. The first housing defines a plurality of inserting ports. The second housing defines a receiving space. The contacts include a plurality of first contacts and second contacts. The first contacts each has a first contact portion extending into the inserting port and a first soldering tail extending out of the insulative housing downwardly. The second contacts each has a second contact portion extending into the receiving space and a second soldering tail extending out of the insulative housing downwardly. All the first soldering tails are arranged closer to the mating face than the second soldering tails.

Abstract: A power socket (100) includes an insulative housing (1), a first contact (21) and a plurality of second contacts (22) attached to the insulative housing (1) and means (185); the insulative housing (1) defines an annular first groove (16) and a first cylinder (18) disposed within the first groove (16); the first groove (16) defines a first inner surface (161) and a first outer surface (162); the first cylinder (18) defines a first passageway (181) extending through a centre portion thereof along the front to back direction; the first contact (21) has a first contact portion (211) extending into the first passageway (181); each second contact (22) has a second contact portion (221) extending into the first groove (16); the means (185) extending into the first groove (16) for preventing a familiar round power plug from being inserted into the first groove (16).

Abstract: A stacked electrical connector (1) includes an insulative housing (2) and a number of contacts (3) retained in the insulative housing (2). The insulative housing (2) includes a first housing (21) and a second housing (22) arranged in an up-to-down direction. The first housing (21) defining a number of inserting ports (213) recessed from a front end thereof. The second housing (22) defines a receiving space (224) to receive a standard USB 2.0 B type plug. The contacts (3) include a number of first contacts (31) retained in the first housing (21) and a number of second contacts (32) retained in the second housing (22). Each first contact (31) has a first contact portion (311) extending into the inserting port (213). Each second contact (32) has a second contact portion (321) and a second soldering portion (324) being arranged in a row in a level direction.
