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.

Abstract translation: 本发明涉及用于在具有相对较高压力的工具室和具有相对较低压力的另一工具室之间传递电流（优选高频AC电流）的井下高电流低阻抗馈通连接器。 本发明的主要目的在于将射频发射机/接收机天线连接到天线的调谐电容器，但是本发明可应用于需要高电流传输通过具有高压差的屏障的任何井下应用。 本发明通过提供优选地具有波状横截面或多翅片横截面的导体来最小化由于高压差而作用在连接器上的力，从而最小化连接器的整个横截面面积 提供足够的导体横截面面积来承载必要的电流量。
