Shielded USB connector system

The present invention relates to a universal serial bus (USB) connector for use in a base unit in a car kit comprising at least two pairs of shielded connection lines. It further relates to a USB cable for providing a shielded connection between a mobile unit and a car kit adaptor. The USB connector for use in a base unit in a car-kit comprises two twin axial connectors including two inner contacts separated by a dielectric and further adapted to be connected to respective complementary connectors and two pairs of shielded connection lines ( and ′). Each pair is connected to a twin axial connector. Further, a shielded USB bridge connects the two pairs of connection lines ( and ′) to four cable terminations to form a USB line. The bridge is mounted in the base unit (′) with the twin axial connectors located in modified guide gins that extend from the base unit.
