Multi deflection canted coil springs and related methods
Canted coil springs with a plurality of interconnected coils that can deflect in at least two different directions with respect to a centerline are disclosed. The ability to deflect in at least two different directions may be utilized in applications that include electrical/mechanical connectors and rotary/static seals. The ability to deflect in at least two different directions may bring increased benefits in terms of geometrical requirements, tolerances, spring orientation, and spring force.
1. A connector assembly comprising a first body and a second body wherein the second body is inserted into the first body;
the first body or the second body having a spring groove comprising two or more walls and a canted coil spring located within the spring groove; and
the canted coil spring comprising a plurality of coils interconnected with one another in a spaced-apart relationship and having a coil centerline passing through the plurality of coils; each coil comprising a plurality of coil sections that are canted at a first preselected angle a with respect to the coil centerline and with respect to a first canting plane that is parallel to the coil centerline and the plurality of coil sections of each of said plurality of coils being canted at a second preselected angle b with respect to the coil centerline and with respect to a second canting plane that is parallel to the coil centerline, said second canting plane being rotated relative to the first canting plane;
wherein each coil of said plurality of coils is deflectable from said first preselected angle a to a further canted angle a′ in a first direction with respect to the first canting plane and from said second preselected angle b to a further canted angle b′ in a second direction with respect to the second canting plane, the first direction and the second direction being generally perpendicular to said coil centerline;
wherein the first direction and the second direction are angled to one another; and
wherein angle a and angle a′ represent angle values with respect to the first canting plane and angle b, and angle b′ represent angle values with respect to the second canting plane.
2. The connector assembly according to claim 1 , wherein the canted coil spring is constrained within the spring groove.
3. The connector assembly according to claim 1 , wherein the two or more walls of the spring groove comprise two sidewalls and a bottom wall located therebetween.
4. The connector assembly according to claim 1 , wherein at least five coils of the plurality of coils each has a bent section to form the second preselected angle b with respect to the coil centerline.
