In one aspect of the invention, a downhole electrical connection system comprises first and second tubular bodies adapted for threaded connection to each other, each tubular body comprising an inner and an outer diameter. First and second electrical conductor assemblies are disposed within the inner diameters of the tubular bodies and are substantially coaxial with the tubular bodies and generally extend the length of the tubular bodies. The first electrical conductor assembly comprises a first electrical contact adapted to abut a second electrical contact of the second electrical conductor assembly when the first and second tubular bodies are coupled together. The first electrical contact is disposed within an elastically deformable wiper, and the elastically deformable wiper is adapted to expose the first electrical contact as it is engaged by the second electrical contact under an axially compressive load.
