Multi-latching mechanisms and related methods
View Patent ↗Dual directional latch devices or connectors are described wherein a first connector component and a second connector component have a first latched position and a second latched position when moving in a first direction and wherein movement in a second direction is also possible when a restriction feature is overcome. As described, opposing magnetic forces, pneumatic pressure, spring force, and a crushable force may be incorporated so that further movement in the second direction must overcome the restriction feature. The dual direction latch devices may be used with articles of manufacture such as with implantable medical devices, door panels, airplane panels, and drilling devices to name a few.
1. A connector comprising a first connector component mated 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 bottom wall;
the pair of grooves comprises a first groove having a first depth and a second groove having a second depth, which has a larger value than the first depth;
an axial canted coil spring comprising a plurality of coils positioned in the first groove and the groove and is movable to be seated in the second groove and the groove; each of said plurality of coils having a major axis and a minor axis and being loaded along the major axis by the first groove and the groove; and
wherein a restriction feature prevents the first connector component from moving relative to the second connector component until overcome by an insertion force to restrict the canted coil spring from being engaged by the second groove and the groove; said restriction feature being selected from the group consisting of magnets creating opposed magnetic forces, electromagnetic forces, a fluid pressure relief bore and a seal, a spring, a shear pin, a collapsible structure, a deflectable structure, a switch trigger, a normally open contact switch, a conductive section, a conductive insert, fluted surfaces, and an inner pin having a groove with a spring.
2. The connector of claim 1 , wherein the first connector component is a pin or a housing and the second connector component is the other one of the pin or the housing.
3. The connector of claim 2 , wherein the housing has a bore and the bore has a constant inside diameter.
4. The connector of claim 3 , wherein the housing has an end wall covering one end of the bore.
5. The connector of claim 1 , wherein the second connector component is attached to an article of manufacture.
6. The connector of claim 1 , further comprising an implantable medical device and wherein the first connector component is located in a header of the implantable medical device.
7. The connector of claim 1 , further comprising an article of manufacture attached to the first connector component or the second connector component.
8. A connector comprising:
a housing comprising a bore and a housing groove having a housing groove depth;
a pin comprising a pin groove having a pin groove depth;
a second groove located adjacent the housing groove or the pin groove, the second groove having a second groove depth that differs from the housing groove depth and the pin groove depth;
an axial canted coil spring comprising a plurality of coils disposed in the bore in a first spring position in a first common groove defined by a combination of the housing groove and the pin groove and is movable relative to the pin and the housing to a second common groove defined by a combination of the housing groove and the second groove or a combination of the pin groove and the second groove; each of said plurality of coils having a major axis and a minor axis and being loaded along the major axis by the housing groove and the pin groove; and
wherein a restriction feature is provided to restrict relative movement between the housing and the pin to restrict the axial canted coil spring from moving to the second common groove until overcome by an insertion force; said restriction feature being selected from the group consisting of magnets creating opposed magnetic forces, electromagnetic forces, a fluid pressure relief bore and a seal, a spring, a shear pin, a collapsible structure, a deflectable structure, a switch trigger, a normally open contact switch, a conductive section, a conductive insert, fluted surfaces, sub-connector assembly, and an inner pin having a groove with a spring.
9. The connector of claim 8 , further comprising an article of manufacture attached to the pin or the housing.
10. The connector of claim 8 , further comprising an implantable medical device and wherein the first housing is located in a header of the implantable medical device.
11. The connector of claim 8 , wherein the second groove comprises a ring and a conductive section disposed therein for electrical communication with the axial canted coil spring.
12. The connector of claim 8 , further comprising an electrical wire connected to the first connector component, the second connector component, or both.
13. The connector of claim 8 , wherein the sub-connector assembly comprises a sub-connector pin having an external groove latched to a sub-connector bore comprising an inner groove and a canted coil spring.
14. The connector of claim 8 , wherein the housing has a bore and the bore has a constant inside diameter.
15. The connector of claim 14 , wherein the housing has an end wall covering one end of the bore.
