Abstract
A circular or plate wave spring that maintains high conductivity under high operating temperatures is provided herein. This is possible due to, at least in part, the conductor being made from a bi-metallic or multi-metallic material which can include a high tensile strength material, such as steel, that maintains strength properties at elevated temperatures cladded with a layer of highly conductive metal, such as copper. The high tensile strength material helps maintain the contact force needed for good conductivity since highly conductive metals and alloys tend to lose their tensile properties at elevated temperatures. The connector is presented here as a wave spring providing inward or outward protrusions for a conductive pin and housing.
