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 (430) 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 (104 and 104'). Each pair is connected to a twin axial connector (430). Further, a shielded USB bridge (100) connects the two pairs of connection lines (104 and 104') to four cable terminations (106) to form a USB line (108).
