Abstract
A downhole electrical transmission system having first and second tubular bodies coupled together by mating threads, each tubular body having a bore. An electrical conductor assembly is disposed within the bore of each tubular body. At least one end of each assembly has an electrical contact surrounded by a dielectric material, the electrical contact and dielectric material forming a polished, planar mating surface. The mating surfaces span an entire cross section of the end and are perpendicular to a central axis of the tubular bodies. The mating surfaces of each electrical conductor assembly are substantially engaged at a compressive load when the tubular bodies are fully mated.

A downhole electrical transmission system comprising:
- first and second tubular bodies coupled together by mating threads, each tubular body comprising a bore;
- an electrical conductor assembly disposed within the bore of each tubular body;
- and
- at least one end of each assembly comprising an electrical contact surrounded by a dielectric naterial, the electrical contact and dielectric material forming a polished, planar mating surface;
- wherein the mating surfaces span an entire cross section of the end and are perpendicular to a central axis of the tubular bodies;
- and wherein the mating surfaces of each electrical conductor assembly are substantially abutted under a compressive load when the tubular bodies are fully mated.
The system of claim 7, wherein the stainless steel armoring is flared on at least one end.
An electrical transmission system comprising:
- a plurality of electrical conductor assemblies, each disposed within a bore of individual components of a downhole drill string;
- each end of the assemblies comprising an electrical contact surrounded by a dielectric material, the electrical contact and dielectric material forming a polished, planar surface;
- the mating surfaces of the electrical conductor assemblies being substantially engaged at a compressive load of at least 1000 psi at mated interfaces of adjacent components;
- and
- at least one antenna attached to a downhole component and in direct electrical communication with the plurality of electrical conductor assemblies, wherein the plurality of electrical conductor assemblies is also in direct electrical communication with surface equipment.
