Each node 50 has a length that is significantly smaller than the length of the first connecting portion 40. The nodes 50 extend in the same plane as the corresponding first connecting portion 40. In an embodiment, the node 50 has an arcuate profile that matches the arcuate profile of the first connector 40.

The annular second connecting portion 42 has a first end 42a and an opposite second end 42b, a first side edge 42c extending between the first end 42a and the second end 42b, and at the first end 42a A second side edge 42d extends between the second end 42b. The contact beam 38 extends from the first end 42a of the second connecting portion 42. The annular second connecting portion 42 is discontinuous such that a gap 52 is formed between the first side edge 42c and the second side edge 42d of the second connecting portion 42. The plurality of second connecting portions 42 substantially fall on an imaginary circle, so that an inner diameter is defined by the second connecting portion 42, as shown in FIG. The inner diameter defined by the second connecting portion 42 is larger than the diameter of the shaft 34. The second connecting portion 42 extends in a longitudinal direction parallel to the center line 44.

The second connecting portion 42 has a plurality of spaced apart nodes 54 extending therefrom. In an embodiment, the plurality of nodes 54 extend in a longitudinal direction parallel to the centerline 44. Each node 54 has a length that is significantly smaller than the length of the second connecting portion 42. In an embodiment, the nodes 54 extend in the same plane as the second connection 42. In an embodiment, the node 54 has an arcuate profile that matches the curved contour of the second connecting portion 42.

In an embodiment, the first diameter defined by the first connection portion 40 is the same as the second diameter defined by the second connection portion 42.

Each contact beam 38 has a first arm 56a extending at an angle from its first connecting portion 40 at a corner 60a, a second arm 56b, and a second arm 56b at a corner 60b1 or 60b2. Extending from the first arm 56a at an angle and at an angle 60c from the second connecting portion 42 at an angle. each The corners 60a, 60b1, 60b2, 60c may be rounded. In each of the contact beams 38, the first arm 56a is inclined inward toward the center line 44 and the second arm 56b is outwardly inclined with respect to the center line 44.

As described herein, the first arm 56a is at an angle a1 or α2 with respect to the centerline 44 of the resilient contact member 30. As described herein, the second arm 56b is at an angle a3 or [alpha]4 with respect to the centerline 44 of the resilient contact member 30. As shown, the angles α1, α2, α3, α4 are taken from the side of the first and second arms 56a, 56b adjacent to the centerline 44.

The first arm 56a and the second arm 56b are at an angle β relative to each other. The angle β is greater than 90 degrees and less than 180 degrees, and more preferably, the angle β is 137 degrees. As shown, the angle β is taken from the side of the first and second arms 56a, 56b opposite the centerline 44.

Some of the contact beams 38 (ie, the first portion) have the first arms 56a having a shorter length than the second arms 56b such that the corners (here defined as "plurality of corners 60b1" or "corners 60b1") are formed adjacent to the respective resilient contacts 30. The first end 30a, while the other contact beams 38 (ie, the second portion) cause the first arm 56a to have a length that is longer than its second arm 56b and thus a corner (here defined as "plurality of corners 60b2" or "corner 60b2" ) is formed adjacent to the second end 30b of each of the elastic contacts 30. Therefore, the corner 60b1 is offset from the corner 60b2 along the longitudinal axis of the resilient contact member 30.

In the case of an unflexed, contact beam 38 having corners 60b1 defines an angle α1, angle α1 is less than 90 degrees and more preferably less than 45 degrees, and defines an angle α3, angle α3 is less than 90 degrees and more preferably Less than 45 degrees. In an undeflected condition, the contact beam 38 having the corner 60b2 defines an angle α2, the angle α2 being less than 90 degrees and more preferably less than 45 degrees, and defining an angle α4, the angle α4 being less than 90 degrees and more preferably less than 45 degrees .

A plurality of corners 60b1 are aligned around the circumference of the resilient contact member 30 and fall within an imaginary circle and define an inner diameter. In an undeflected condition, the inner diameter defined by the plurality of corners 60b1 is smaller than the diameter of the shaft 34. A plurality of corners 60b2 are aligned around the circumference of the resilient contact member 30 and fall into an imaginary circle and define an inner diameter. In an undeflected condition, the inner diameter defined by the plurality of corners 60b2 is smaller than the diameter of the shaft 34.
