Abstract
A flexible electrical connector for borehole telemetry apparatus is presented wherein the electrical connector includes an elongated metal tube having an intermediate section coiled around the exhaust shroud of a mud turbine. Electrical conductors are housed within the metal tube, and the tube is internally pressurized with oil, the pressure of the oil being maintained equal to the drilling mud pressure by a bellows exposed to the drilling mud.
