Abstract
Coil springs with a plurality of interconnected coils each being defined by a wire path that results in a coil cross section that, when viewed along the coil axis, has at least two differentiated spaces each confined by the wire. Assemblies using such coil springs are also disclosed.
Claims22
A coil spring comprising:
- a plurality of interconnected canted coils comprising a coil axis;
- each coil being defined by a wire having a wire path that results in a coil cross section that, when viewed along the coil axis, comprises at least a first space and a second space differentiated from each other and each confined by the wire;
- and
- wherein each coil has a coil width that is greater than a coil height to increase surface contact areas of the coil.

A method for forming a coil spring comprising:
- coiling a wire to form a plurality of interconnected canted coils comprising a coil axis, each coil being defined by a wire having wire path that results in a coil cross section that, when viewed along the coil axis, comprises at least a first space and a second space differentiated from each other and each confined by the wire;
- repeating the coiling to produce at least three interconnected coils;
- and
- wherein each coil has a coil width that is greater than a coil height to increase surface contact areas of the coil.
1 more element
A connector assembly comprising:
- a housing having a bore;
- a pin located in said bore of said housing;
- a groove in said housing or on said pin;
- a coil spring in said groove to connect said pin to said housing;
- wherein said coil spring comprises a plurality of interconnected canted coils comprising a coil axis, each coil being defined by a wire having a wire path that results in a coil cross section that, when viewed along the coil axis, comprises at least a first space and a second space differentiated from each other and each confined by the wire;
- and
- wherein each coil has a coil width that is greater than a coil height to increase surface contact areas of the coil.
