Abstract
An overvoltage protector assembly utilizes a gas tube having an electrically conductive terminal and an electrically conductive end cap for being selectively brought into electrical contact with the terminal to divert surges to ground. A toroidal non-conductive element having a central hole is disposed between an end cap and the terminal of the gas tube. A fusible element formed of a fluxed solder pellet is also disposed between the end cap and the terminal of the gas tube. The end cap includes at least one aperture and a raised projection on its outer surface so that axial forces applied by a spring clip are centrally applied to the end cap. Molten solder flows through the central hole in the non-conductive element and the aperture in the end cap when the overvoltage protector assembly overheats so that the end cap and the terminal are in electrical contact.
