Abstract
Abstract A board-to-board connector assembly (10) includes a plug connector (12) and a receptacle connector (14), each of which includes an insulative housing (16, 60) and a plurality of contacts (26, 64) therein. A pair of grounding shields or grounding plates (39) are positioned on two sides of the housing (16) of the plug connector (12) wherein a plurality of grounding pins (44) of each grounding plates (39) are selectively connected to some of the contacts (26) of the plug connector (12), and a corresponding number of engagement arms (42) are positioned opposite to such grounding pins (44), respectively. Correspondingly, a corresponding number of grounding contacts (72) are disposed in the housing (64) of the receptacle connector (14) wherein an outer portion or the engagement section (77) of each grounding contact (72) engages the corresponding engagement arm (42) of the grounding plate (39), and an inner portion or the abutment section (78) thereof engages the corresponding contact of the receptacle connector (14). Thus, EMI or the undesired noises can be eliminated from such selected contacts (26, 64) and grounding pins (44) and grounding contacts (72) through the plates (39).
