First Claim
1. 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 material, the electrical contact and dielectric material forming a polished, planar mating surface;
the planar mating surface being spring-loaded by a resilient material;
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.

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.
