Abstract
Abstract A connector for impedance matched, low capacitance connection to coaxial cable is disclosed. The connector includes a conductive housing which supports in electrical isolation an insulation displacing electrical contact. A clamping element forces the center conductor of the coaxial cable down onto the insulation displacing portion contact for electrical termination. An assembly nut supports the drain wire of the coaxial cable, in electrical engagement therewith, to place the connector housing in electrical continuity with the drain wire of the cable.
