A cable connector includes a base and a mating portion extending downwardly from a lower side of the base, and an upper and a lower platform around an upper side of the base. First and second rows of contacts include connecting sections. The connecting sections of the first row are exposed upon the lower platform and the connecting sections of the second row are exposed upon the upper platform. Upper and lower rows of wires are located above the housing. Two grounding brackets are mounted upon the upper and lower platforms. Each bracket includes bulged sections and tails. Inner conductors of the wires are connected to the connecting sections of the differential-pair contacts, the braiding layers of the wires are sandwiched between the bulged sections and the housing in the vertical direction, and the tails are connected to the connecting sections of the grounding contacts.
