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 depending on a stop feature. As described, a combination key and key way, a movable sleeve, a stop flange, and a threaded sleeve may be provided to stop movement in the second direction. 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 comprising a cylindrical bore with a cylindrical second connector component received in the cylindrical bore, an annular first connector groove located in or on an inner surface of the bore of the first connector component and an annular second connector groove located in or on an outer surface of the second connector component;
the first connector groove having at least one of a bottom wall and two tapered side walls that are tapered relatively to a lengthwise axis of the first connector component;
the first connector groove of the first connector component and the second connector grove of the second connector component defining a first common groove having a first common groove shape and size;
an additional annular groove located on the first or second connector component adjacent one of the first connector groove and the second connector groove; the first connector groove or the second connector groove together with the additional groove defining a second common groove having a second common groove shape and size;
a canted coil spring positioned in the first common groove and loaded along a major axis of the canted coil spring in a first position, the canted coil spring being positionable in the second common groove in a second position in which the canted coil spring is not loaded along the major axis;
a removable stop feature comprising a removable or a multi-part shoulder member having opposing first and second surfaces positioned on the second connector component with the first surface abutting the first connector component to prevent the canted coil spring from moving to the second position from the first position; and
an extended feature extending from the outer surface of the second connector component having a surface for abutting the second surface of the removable stop feature to prevent relative movement of the second component into the first component when the canted coil spring is in the first position.
2. The connector of claim 1 , wherein the additional annular groove is located in the cylindrical bore of the first connector component.
3. The connector of claim 1 , wherein the canted coil spring is rotatable when in the second position.
4. 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.
5. The connector of claim 1 , wherein the extended feature is a flange, a pin, a rod, or a sleeve.
6. A connector comprising a first connector component comprising a cylindrical bore mated with a cylindrical second connector component received in the cylindrical bore, an annular first connector groove provided in or on an inner surface of the bore of the first connector component and an annular second connector groove provided in or on an outer surface of the second connector component; the first connector groove of the first connector component and the second connector groove of the second connector component defining a first common groove having a first common groove shape and size;
an additional annular groove located on the first or second connector component adjacent one of the first connector groove and the second connector groove; the first connector groove or the second connector groove together with the additional groove defining a second common groove having a second common groove shape and size;
a canted coil spring positioned in the first common groove and loaded along its major axis in a first position, and is positionable in the second common groove in a second position;
a stop feature comprising abutting surfaces disposed on the first and second connector components to prevent relative movement between the connector components to thereby prevent the canted coil spring from moving to the second common groove, said abutting surfaces comprising a surface on an extended feature extending from the outer surface of the second connector component being blocked by another surface disposed on the first connector component; and
wherein the canted coil spring is not loaded along its major axis and is rotatable to its relaxed position inside the second common groove when the extended feature is aligned with a keyway or recess in the first connector component allowing the canted coil spring to be moved to the second common groove such that the surface of the extended feature on the second connector component is no longer blocked by the another surface.
7. The connector of claim 6 , wherein the extended feature is a flange, a pin, a rod, or a sleeve.
8. The connector of claim 6 , wherein the extended feature abuts against the first connector component to limit movement of the first connector component in a first direction towards the second connector component when the canted coil spring is in the second common groove but not in a second direction, opposite the first direction.
