Electrical connector using a canted coil multi-metallic wire

摘要

A canted coil spring made from multi-metallic wire to achieve combinations of desired material characteristics of different metals is discussed. Wire to be used in canted coil springs can have two or more metals oriented co-axially along such wire, such as an outer layer of one metal having one set of properties, and a core of a different metal having a different set of properties, that will achieve a single solid, multi-metallic wire with enhanced performance over a single material canted coil spring. Such features may be found advantageous in electrical applications, such as where both high electrical conductivity and high strength properties are desired.

1. A method for connecting and conducting electricity between a first body and a second body in an application above 200 degrees Celsius comprising:
inserting an elongated body of the second body comprising an external groove into a bore of the first body comprising an internal groove; positioning a canted coil spring comprising a plurality of coils in a common groove defined by the first body and the second body so that the plurality of coils contact the external groove and the internal groove; and applying electrical current between the first body and the second body and through the spring; exposing the first body and the second body to a temperature greater than 210 degrees Celsius; and wherein said spring comprising an inner core made from a highly electrically conductive material with a circumference and a secondary layer outside the core and completely surrounding the circumference of the core; said secondary layer comprising a high modulus and high tensile strength material.
