ABSTRACT:
An internal electrical interconnect coupler of an electrical conductor assembly for use with a tubular fluid conductor composed of lengths of pipe having their ends interconnected in spaced relationship by external couplers wherein an electrical conductor for said assembly is provided by thin ductile electrically conductive tubes disposed within the pipe lengths and electrically insulated therefrom by complementary pliant dielectric sheaths which envelope said tubes. Flared extremities of each sheathed tube conform to internal end portions of each pipe length so as to anchor said tube against relative displacement. Internal interconnect coupler is adapted to be mounted in box end of each pipe length or its external coupler and has an electric conductor body for electrically connecting the end portions of adjacent inner conductor tubes, and an elastic dielectric collar is mounted on the body for engaging the contiguous box and pin ends of adjacent pipe lengths to electrically insulate said tube extremities from adjacent pipe and external coupler interior surfaces. When coupled, external couplers of adjacent pipe lengths deform elastic collar between box and pin pipe ends into fluid tight sealing engagement with tube extremities and adjacent pipe and coupler internal surfaces. The inner end portion of each electrical conductor body is expandable into engagement with the bore of the tube within each pipe length inwardly adjacent its box to secure internal interconnect coupler therein.
