Spring latching connectors radially and axially mounted
View Patent ↗A spring latching connector includes a housing having a bore therethrough, a piston slidably received in said bore, circular groove formed in one of said bore and piston and a circular coil spring disposed in said groove for latching said piston and housing together. The groove is sized and shaped for controlling, in combination with a spring configuration, disconnect and connect forces of the spring latching connection.
1. A spring latching connector comprising:
a housing having a bore therethrough;
a piston slidably received in said bore;
a groove formed in one of said bore and piston;
a coil spring disposed in said groove for latching said piston and housing together, said groove being sized and shaped for controlling, in combination with a spring configuration, disconnect and connect forces of said spring latching connector, said coil spring having coils with a major and a minor axis; and
a cavity formed in said groove for positioning a point of coil/groove contact in relation to an end point of the coil major axis in order to determine the disconnect and connect forces between the spring and the housing.
2. The connector according to claim 1 wherein said groove and coil spring are circular.
3. The connector according to claim 1 wherein the groove cavity positions the point of contact proximate the coil major axis in order to maximize the disconnect force.
4. The connector according to claim 1 wherein the groove cavity positions the point of contact proximate to the end point of the minor axis in order to minimize the disconnect force.
5. The connector according to claim 1 wherein a coil height and a groove width are adjusted to control the disconnect and connect forces.
6. The connector according to claim 1 wherein a position between a coil centerline along the minor axis in relation to a groove depth is adjusted to control disconnect and connect forces.
7. The connector according to claim 1 wherein said spring is turnable in said groove for enhancing electrical conduction between said piston and said housing by removing oxidation on said spring.
8. The connector according to claim 6 wherein said groove includes an uneven bottom for scraping said spring as said spring turns therepast.
9. The connector according to claim 1 wherein said spring is a counterclockwise radial spring.
10. The connector according to claim 1 wherein said spring is a clockwise radial spring.
11. The connector according to claim 1 wherein said spring is an axial spring having a back angle at an inside diameter of spring coils and a front angle on an outside diameter of the spring coils.
12. The connector according to claim 1 wherein said spring is an axial spring having a back angle on an outside diameter of spring coils and a front angle on an inside diameter of the spring coils.
13. The connector according to claim 1 wherein said spring is an axial spring and the groove has a width smaller than a coil height in order to increase both spring retention force and increase insertion force.
14. The connector according to claim 13 wherein the axial spring has offset coils in order to decrease insertion force.
15. The connector according to claim 1 wherein said groove has a tapered bottom.
16. The connector according to claim 13 wherein said spring is axial spring having a back angle at an inside diameter of spring coils and a front angle on an outside diameter of the spring coils.
17. The connector according to claim 13 wherein said spring is an axial spring having a back angle at an outside diameter of spring coils and a front angle on an inside diameter of the spring coils.
18. The connector according to claim 1 wherein said groove has a flat bottom.
19. The connector according to claim 1 wherein said groove has a V-bottom.
20. The connector according to claim 1 wherein said groove has a tapered V-bottom groove.
21. The connector according to claim 1 wherein said groove has a semi-tapered bottom.
22. The connector according to claim 1 wherein said groove has a round bottom with a shoulder therein.
23. The connector according to claim 1 wherein said groove has an inverted V-bottom.
24. The connector according to claim 1 wherein said groove has a V-bottom with different angle subtending sides of said grooves.
25. The connector according to claim 1 wherein said groove is a dovetail groove.
26. The connector according to claim 1 wherein the groove is threaded.
27. The connector according to claim 26 wherein a groove width is smaller than a coil height.
28. The connector according to claim 1 further comprising a plurality of circular grooves formed in one of said bore and piston and a plurality of coil springs, one disposed in each of the grooves.
29. The connector according to claim 1 further comprising a plurality of coil springs disposed in the groove.
30. The connector according to claim 1 further comprising a elastomer disposed with said spring in said groove for providing both conductivity and environmental sealing.
31. The connector according to claim 30 wherein said elastomer coats coils of said spring.
32. The connector according to claim 30 wherein said elastomer fills coils of said spring.
33. The connector according to claim 32 wherein said elastomer is solid.
34. The connector according to claim 32 wherein said elastomer has a hollow core.
35. The connector according to claim 32 wherein perimeters of the spring coils are not covered by said elastomer.
