    摘要: Multilayered canted coil springs and methods that improve mechanical, electrical and thermal properties of canted coil springs. In some embodiments, properties of dissimilar materials are combined into the spring using various material layers. For example, in one embodiment a protective or high strength outer layer material shields a more sensitive inner core material from harsh environments and conditions. The inner core material may be a highly electrically conductive material, with the outer layer material having an electrical conductivity lower than the core. In various embodiments the following characteristics of the spring are improved: electrical and/or thermal conductivity, corrosion resistance, biocompatibility, temperature resistance, stress relaxation, variable frictional force, and wear resistance in harsh environments and conditions.

    摘要: A coil spring for use in a cavity, such as in a groove of a pin, a housing, or both. The cavity can also be part of a seal assembly. The coil spring can have a longitudinal component positioned within the plurality of interconnected coils that runs along the spring coil axis in order to increase rigidity of the coil spring. The longitudinal component applies a load against the coil spring and/or provides restriction against the coil spring taking a shape or size different than that of the coil spring retaining groove.
