Dual directional latch
View Patent ↗The present device, system, and method pertain to locking and/or latching mechanisms that utilize canted coil springs and specific groove geometries in connecting parts to achieve locking and/or latching. In specific locking and/or latching embodiments, built in release features are provided to enable unlatching even after being locked, such as by moving in the opposite direction as when moving the connector to lock. Unlatching can implemented by rotating the spring to permit moving in the opposite direction.
1. A connector comprising a first connector component for mating with a second connector component, a groove located in or on the first connector component or the second connector component and a pair of grooves located in or on the other one of the first connector component or the second connector component;
the groove having two sidewalls and a flat bottom wall;
the pair of grooves comprises a first groove having a first depth and a second groove having a second depth, which differs from the first depth; and
wherein a canted coil spring is positioned in the first groove and the groove and is movable to be seated in the second groove and the groove.
2. The connector of claim 1 , wherein the first connector component is in electrical communication with a first source and the second connector component is in electrical communication with a second source.
3. The connector of claim 2 , wherein the canted coil spring is made from a copper material, a copper alloy material, a high tensile strength steel, or combination thereof.
4. The connector of claim 2 , wherein the canted coil spring is coated with a conductive material.
5. The connector of claim 1 , wherein the first connector component is a pin and the second component is a housing, which has a bore for receiving the pin.
6. The connector of claim 1 , wherein the first component is a housing and the second component is a pin, and wherein the housing comprises a bore for receiving the pin.
7. The connector of claim 1 , wherein the second groove comprises at least one tapered side wall.
8. The connector of claim 1 , wherein the second groove is both wider and deeper than the first groove.
9. A method for using a connector comprising
moving a first connector component relative to a second connector component to position a canted coil spring in a first groove for locking;
moving the canted coil spring to a location adjacent the first groove for holding,
moving the canted coil spring to a second groove for latching,
moving the canted coil spring back to the first groove; and
wherein the first connector component or the second connector component comprises a groove having two side walls and a flat bottom groove.
10. The method of claim 9 , further comprising separating the first connector component from the second connector component.
11. The method of claim 9 , wherein the second component comprises both the first groove and the second groove.
12. The method of claim 11 , wherein the second groove has a larger depth than the first groove.
13. The method of claim 9 , wherein the first component comprises both the first groove and the second groove.
14. The method of claim 9 , wherein the first component, the second component, and the spring all comprise an electrically conductive material.
15. A connector comprising:
a housing comprising a bore and a housing groove having a housing groove configuration;
a pin comprising a pin groove having a pin groove configuration;
an axial canted coil spring disposed in the bore in a first spring position defined by a combination of the housing groove and the pin groove;
a second groove located adjacent the housing groove or the pin groove, the second groove having a second groove configuration with a second groove depth that differs from the housing groove configuration and the pin groove configuration; and
wherein the canted coil spring is movable relative to the pin and the housing.
16. The connector of claim 15 , wherein the second groove is located on the pin and adjacent the pin groove.
17. The connector of claim 15 , wherein the second groove is located in the bore of the housing, adjacent the housing groove.
18. The connector of claim 15 , wherein the canted coil spring is rotatable relative to the housing by rotating from a first turn angle when in the first spring position to a second turn angle when in a second spring position.
19. The connector of claim 15 , wherein the pin is movable in a first direction but not a second, opposite, direction when the canted coil spring is in the first spring position.
20. The connector of claim 19 , wherein the pin is movable in the second direction when the canted coil spring is in a second spring position, which is defined at least in part by the second groove.
21. The connector of claim 15 , wherein the housing groove configuration comprises a bottom wall and two sidewalls.
22. The connector of claim 21 , wherein the two sidewalls are generally parallel to one another.
23. The connector of claim 22 , wherein the bottom wall is angled relative to the two sidewalls.
24. The connector of claim 15 , wherein the pin has a round cross-section, a square cross-section, a rectangular cross-section, an oval cross-section, a polygonal cross-section, or a triangular cross-section.
