An electrical connector (100) includes a number of conductive contacts (21-28), a first capacitive plate (31) and an insulator (40) fixing the number of conductive contacts (21-28) and the capacitive plate (31). The number of conductive contacts further include a first pair of conductive contacts (21, 22) to form a first signal channel and a second pair of conductive contacts (23, 26) to form a second signal channel. The first capacitive plate (31) is electrically connected with one conductive contact (23) of the second pair. The first capacitive plate (31) is disposed closer to one conductive contact (21) of the first pair than the conductive contact (23) which the first capacitive plate (31) is electrically connected to. The insulator (40) is partially hollowed out between the first capacitive plate (31) and the corresponding conductive contact (21) of the first pair to improve the crosstalk between the first and the second signal channels.
