Grounding system for a heated hose

摘要

A grounded electrical circuit in a heated hose is provided. In one embodiment, the heated hose assembly includes: a flexible hose body; a first and a second heating wires and a hose ground wire each extending longitudinally and parallel to an axis of the hose body and within an inner wall; a first fluid coupling provided on the first end portion of the flexible hose body, the first fluid coupling comprising a stem inserted into the flexible hose body and radially clamping an end of the hose ground wire against an inner surface of the inner wall, such that a contact between the first fluid coupling and the end of the hose ground wire grounds the hose ground wire; a power cord electrically connected to the first and second heating wires and to the hose ground wire; and a thermostat electrically connected to the first and second heating wires.
