Modular galvanic current control resistor assembly for mounting on an electric immersion heater

摘要

A modular galvanic current control resistor assembly for application to a metallic sheathed heating element of a domestic water heating tank to prevent heating element corrosion includes a circular metallic disc adapted to fit over the sheath ends of a U-shaped immersion heating element protruding in electrically insulated relationship through a metallic screw plug or the like mounting means used to affix the heating element to the tank, an electrically insulating gasket coextensive with the disc and a galvanic current control resistor having a pair of leads. The sheath ends of the heating element extend through the gasket and disc with portions of the disc around each sheath end crimped, compressed or friction fitted into electrical contact therewith. The galvanic current control resistor is received in aligned openings in the disc and gasket and has one lead positioned between the disc and gasket and in electrical contact with the disc and its other lead extending through the opening to the other side of the gasket for electrical contact with the screw plug or like mounting means when the assembly is mounted thereon.
