Data Transmission Apparatus Comprising a Helically Wound Conductor

摘要

In one aspect of the present invention, an inductive coupling comprises an inner and outer casing. The inner casing comprises an inner trough formed into an exterior surface with an inner electrical conductor disposed within the inner trough. The outer casing comprises an outer trough formed into the interior surface with an outer electrical conductor disposed within the outer trough. The outer casing is configured to encircle the inner casing such that the inner electrical conductor is in magnetic communication with the outer electrical conductor. A helical geometry is formed in at least one of the inner or outer troughs. The inner and outer casings are configured to move relative to each other.
