Conductive elastic component for electrically connecting an electronic device with a cradle
View Patent ↗A conductive elastic component for electrically connecting an electronic device with a cradle includes a plurality of fingers, a first metallic plate connecting first ends of the plurality of fingers, and a second metallic plate connecting second ends of the plurality of fingers. Each finger has a first end for being mechanically connected to the cradle, a first segment spanning between the first end and a first point, and a second segment spanning between the first point and a second end. The second segment of each finger has a curved contact region for contacting the input node of the electronic device. An angle between a line connecting the first point and the first end and a line connecting the first point and the second end is an acute angle. In addition, the centerline along the lengths of the first and second segments resides in a same plane.
1. A conductive finger for electrically connecting an input node of an electronic device with an input node of a cradle comprising:
a first end for being mechanically connected to the cradle;
a first segment, spanning between the first end and a first point, the first segment comprising an S-bend, wherein none of convex or concave sides of the S-bend face an opposite side of the conductive finger; and
a second segment, spanning between the first point and a second end, the second segment having a curved contact region for contacting the input node of the electronic device, an angle between a line connecting the first point and the first end and a line connecting the first point and the second end being an acute angle, a concave side of the curved contact region facing the first segment;
wherein centerlines along the lengths of the first and second segments reside in a same plane.
2. The conductive finger of claim 1 wherein the first segment further comprises a bend between the S-bend and the first point, wherein the bend is of an obtuse angle.
3. The conductive finger of claim 2 wherein a concave side of the bend of the first segment faces the second segment.
4. The conductive finger of claim 2 wherein a concave side of the bend and the concave side of the curved contact region face inward toward an opposite side of the conductive finger.
5. The conductive finger of claim 1 wherein the acute angle is between 15 and 45 degrees.
6. The conductive finger of claim 1 wherein the first and second segments and have widths substantially perpendicular to the plane and have thicknesses substantially perpendicular to their respective widths, and a width-to-thickness ratio of the first and second segments is greater than 10 to 1.
7. The conductive finger of claim 1 being made of metal.
8. The conductive finger of claim 1 wherein the second segment further comprises a flat portion between the second end and the curved contact region for resting against an interior surface of the cradle.
9. A conductive elastic component for electrically connecting an electronic device with a cradle comprising:
a plurality of conductive fingers, each conductive finger comprising:
a first end for being mechanically connected to the cradle;
a first segment, spanning between the first end and a first point, the first segment comprising an S-bend, wherein none of convex or concave sides of the S-bend face an opposite side of the conductive finger; and
a second segment, spanning between the first point and a second end, the second segment having a curved contact region for contacting an input node of the electronic device, an angle between a line connecting the first point and the first end and a line connecting the first point and the second end being an acute angle, a concave side of the curved contact region facing the first segment, wherein centerlines along the lengths of the first and second segments reside in a same plane; and
a first metallic plate connecting first ends of the plurality of conductive fingers; and
a second metallic plate connecting second ends of the plurality of conductive fingers.
