A cable connector that includes a substrate having a plurality of conductive pads and at least one grounding pad. The cable connector further includes twin axial cable that includes a first conductor and second conductor, a first insulator that surrounds the first conductor, and a second insulator that surrounds the second conductor. The twin axial cable further includes a ground shield that surrounds the first and second insulator. The first conductor is electrically connected to one conductive pad and the second conductor is electrically connected to another of the conductive pads. The ground shield is electrically connected to the grounding pad. A shielding structure is mounted to the substrate and is electrically connected to the grounding pad. The shielding structure includes a cap and a plurality of sidewalls extending from the cap to the substrate. The twin axial cable is positioned between the side walls.
