Grounding system for a heated hose

摘要

A sturdy electrical power circuit and grounding circuit for an electrically-heated hose is formed by electrically connecting a grounding wire extending along the length of the hose to a pair of fluid couplings fitted on opposite ends of the hose. The grounding wire is mechanically clamped against the inner wall of the hose by radially-outwardly expanding a tube on each coupling against the grounding wire to secure the grounding wire in place while simultaneously forming an electrical connection between the grounding wire and the fluid couplings.
