An electrical connector assembly (1) includes an insulating housing (2) and an electrical subassembly (3) disposed within the housing. The housing defines a receiving space (23) in a rear face (202), and at least one groove (26) and recess (28) extending in a back-to-front direction beside the receiving space. The electrical subassembly includes first and second printed circuit boards (320, 340) each having at least one side conductor (325, 345) attached thereon, a pair of magnetic modules (300, 300′) respectively connecting with the first and second PCBs for suppressing noise, and a metal plate (4) sandwiched between the magnetic modules. The metal plate has at least one projection (48). When the electrical subassembly is assembled to the housing through the receiving space, the at least one side conductor and projection are respectively received in the at least one groove and recess, thereby ensuring the electrical subassembly being accurately inserted into the housing.

An electrical connector (1) includes an insulative housing (10) and a number of contacts (28) attached to the housing. The contacts each have a contact tail (36) downwardly extending beyond a mounting surface (32) of the insulative housing for inserting into throughholes (42) of a PCB (40). The contact tails are overlapped in pairs and each pair of contact tails is inserted into the same throughhole of the PCB. Some pairs of contact tails, called retention contact tails (68), have protrusions (52) deviating from each other for bearing against peripheral walls of the throughholes of the PCB thereby producing retention force. The other pairs of contact tails, called non-retention contact tails (70), do not have protrusions and do not interfere with peripheral walls of the other throughholes thereby reducing the insertion force. The retention contact tails can be modified to the non-retention contact tails by severing the protrusions therefrom.

An electrical connector (100) mounted on a main printed circuit board (PCB), includes an insulative housing (1) defining at least one cavity (11, 12), an insert module (3) received in the housing, a rear ground plate (4), and an outer shell (2). The insert module includes a plurality of contacts (31, 32) extending into the cavity of the housing, and at least one internal PCB (53) containing at least one ground pad. The rear ground plate is coupled to a rear portion of the insert module and includes at least one upper grounding contact (41) electrically connecting with ground pad of the internal PCB and at least one lower grounding contact (43) extending downwardly for engaging with a ground pad of the main PCB. The outer shell is provided for surrounding the insulative housing with the rear ground plate sandwiched therebetween.
