    Abstract: The present invention is directed to a downhole, high-current, low-impedance, feed-through connector for passing electrical current, preferably high frequency AC current, between a tool compartment having relatively high pressure and another tool compartment having relatively low pressure. The primary intended application of the present invention is to connect a radio frequency transmitter/receiver antenna to the antenna's tuning capacitors, but the present invention is applicable to any downhole application requiring the transmission of high electrical current across a barrier having a high pressure differential. This invention minimizes the force acting on the connector due to the high pressure differential by providing a conductor preferably having either a wave-like cross-section or a multi-finned cross-section, thereby minimizing the overall cross-sectional area of the connector yet providing sufficient cross-sectional area of the conductor to carry the necessary amount of electrical current.
