Electrical connectors with linear springs and related methods
Connector assemblies having a housing, a pin, and a spring length having two free ends are used as a mechanical connector to secure two objects or components together or an electrical connector for placing two sources in electrical communication with one another. The spring length can be a canted coil spring in which the two free ends are not connected to one another and the coils can have an elliptical shape or a complex coil shape. The spring length can be used with a retaining component, can be used in a recessed slot formed with the housing or the pin, or both with a retaining component and with a recessed slot.

a pin with a tapered insertion end is positioned through the ring; and
wherein the spring length with two free ends contacts the pin and the finger.
2. The connector assembly of claim 1 , wherein the pin comprises a recessed slot and the spring length is positioned, at least in part, in the recessed slot.
3. The connector assembly of claim 2 , wherein the recessed slot comprises two sidewalls, a bottom wall located between the two sidewalls, and two end walls connected to the two sidewalls.
4. The connector assembly of claim 3 , wherein at least one of the two sidewalls is a tapered sidewall and is tapered relative to the bottom wall.
5. The connector assembly of claim 4 , wherein the recessed slot is a first recessed slot, and further comprising a second recessed slot located on the pin, said second recessed slot comprising two sidewalls.
6. The connector assembly of claim 1 , wherein the ring of the retaining component has a gap.
7. The connector assembly of claim 1 , wherein the finger is a first finger and the spring length is a first spring length; and further comprising a second finger connected to the ring and a second spring length; and wherein the second spring length is located with the second finger.
8. The connector assembly of claim 1 , wherein the ring contacts an interior surface of the housing before the pin is inserted in a bore of the housing or the ring contacts the pin before the pin is inserted in a bore of the housing.
9. The connector assembly of claim 1 , wherein the finger is unitarily formed with the ring.
10. The connector assembly of claim 9 , wherein the finger has a first bend, a second bend, and a free end that points in a direction of the ring and away from the second bend.
11. The connector assembly of claim 1 , wherein the spring length is a canted coil spring length comprising a plurality of interconnected coils all canted in a same general direction and the housing has a round housing wall or has a polygonal shaped housing wall.
12. The connector assembly of claim 1 , wherein the retaining component is formed from a wire or by stamping a metal sheet with one or more cutting dies.
13. The connector assembly of claim 1 , wherein the finger has a bend connected to the ring and a free end pointing away from the ring and having a bent retaining tip.
14. The connector assembly of claim 1 , wherein the housing comprises a body with a wall thickness, an exterior surface, and an interior surface defining a bore; and wherein a recessed slot is formed with the housing or the pin.
15. The connector assembly of claim 14 , wherein the pin is rotatable about a lengthwise axis of the pin to separate from the bore of the housing.
16. A connector assembly comprising:
a housing comprising a body with a wall thickness, an exterior surface, and an interior surface defining a bore, the bore having a lengthwise axis;
a pin comprising a tapered insertion end and an exterior surface defining an exterior diameter;
a canted coil spring length comprising a plurality of interconnected coils all canted along a same direction, the canted coil spring length having free ends that are not connected positioned in a slot, and wherein the spring length is aligned substantially parallel to the lengthwise axis of the bore and located between and in contact with the housing and the pin to complete an electrical path; and
wherein the pin, the housing, and the canted coil spring length are made from a same electrically conductive material or from different electrically conductive materials, and wherein the slot is recessed from the interior surface defining the bore of the electrically conductive housing or from the exterior surface of the electrically conductive pin.
17. The connector assembly of claim 16 , wherein the slot comprises two sidewalls and a bottom wall located therebetween, a V-shape groove, or a V-shape groove with a subtended surface between two slanted surfaces.
18. The connector assembly of claim 17 , wherein the two sidewalls are generally parallel to one another or at least one of the two sidewalls is a tapered sidewall and is tapered relative to the bottom wall.
19. The connector assembly of claim 16 , wherein the slot is a first slot and further comprises a second slot spaced from the first slot with a spring length located in the second slot.
20. The connector assembly of claim 16 , wherein the housing has a unitarily formed finger and the canted coil spring length is located on the finger.
21. The connector assembly of claim 16 , wherein the pin is rotatable about a lengthwise axis of the pin to compress the plurality of interconnected coils of the canted coil spring length from a first canting angle to a second canting angle.
22. The connector assembly of claim 16 , wherein the pin has a round cross-sectional shape or a polygonal shape.
23. A method of using a connector assembly comprising:
inserting a singular piece pin having an exterior surface defining an exterior diameter and a tapered insertion end into a bore of a singular piece housing, said housing having an exterior surface, an interior surface defining the bore, and a lengthwise axis or inserting a pin having a tapered insertion end into a bore of a ring retaining component having two fingers extending from the ring such that each of the two fingers is aligned substantially parallel to a central axis of the ring;
placing and contacting a canted coil spring length having two free ends that are not connected with a slot recessed from the interior surface of the housing or from the exterior surface of the pin, wherein the canted coil spring length is aligned substantially parallel to the lengthwise axis of the housing and the pin or contacting two spring lengths each with two free ends and each mounted on a respective one of the two fingers of the retaining component with the pin;
wherein the spring length or the two spring lengths each is a canted coil spring comprising a plurality of interconnected coils.
24. The method of claim 23 , wherein the ring of the retaining component is fastened to a hardware.
