A cable connector includes a contact module enclosed within a case. The contact module includes an upper part and a lower part stacked with each other. The upper part includes an upper insulator and plural upper contacts and a metallic upper shield attached upon the upper insulator. The wires include inner conductors connected to differential-pair signal contacts of the plural upper contacts. The upper shield defines a plurality of front spring fingers respectively connected to the corresponding grounding contacts and a plurality of rear spring fingers respectively connected to the braiding layers of the corresponding wires.
