摘要： A backplane connector includes a number of conductive terminals, an insulating frame, a first metal shield and a second metal shield. Each conductive terminal includes a connection portion. The conductive terminals include differential signal terminals, a first ground terminal and a second ground terminal. The first metal shield and the second metal shield are respectively in contact with two opposite side surfaces of the first ground terminal and the second ground terminal. As a result, a shielding cavity surrounding the connection portions of the differential signal terminals is formed. This arrangement can provide better shielding for the differential signal terminals over the length of the connection portion, reduce crosstalk, and improve the quality of signal transmission.
