Dual insulation structure for a heating device

Abstract

This utility model relates to the field of electric heating equipment technology, and in particular to a double insulation structure for a heating device, including an electrode and a connector. The connector includes a conductive plate with a mounting hole, and further includes: a fixing hole on the electrode; an insulating component adapted to be interference-fitted into the fixing hole, the insulating component having a raised ring, the mounting hole and the raised ring being clearance-fitted, and an insulating chamber forming inside the raised ring; and a pressing component that is movably engaged with the raised ring and can slide along the axial direction of the raised ring, one side of the pressing component being located inside the insulating chamber and having a pressing ring. This utility model, by interference-fitting the insulating component into the fixing hole on the electrode, ensures that when a screw is connected to the insulating component, the raised ring on the insulating component isolates the screw from external contact, and the nut position of the screw is completely embedded in the insulating chamber, achieving full-coverage insulation. The raised ring structure of the raised ring is equivalent to forming an insulating barrier around the screw.
