Abstract

A compressible electrical contact, manufactured from a tube, includes a first contact end, a second contact end opposing the first contact end, and a medial portion disposed between the first contact end and the second contact end. The medial portion includes a plurality of divaricated cut sections based on at least one divaricating pattern cut into the tube. The at least one divaricating pattern preferably includes an upper tapered section and a lower tapered section such that a plurality of tapered slots are formed after the tube is cut and when the compressible electrical contact is substantially compressed.

First claim

What is claimed is:

1 . A compressible electrical contact, comprising:
a first contact end; a second contact end opposing the first contact end; and a plurality of divaricated-cut sections positioned between the first contact end and the second contact end, each of the plurality of divaricated-cut sections being defined by at least one cut angle measured between a pair of outwardly extending opposing inner surfaces, an innermost cut distance, and an outermost cut distance, wherein the innermost cut distance is smaller than the outermost cut distance, wherein in a substantially relaxed state, each pair of opposing inner surfaces extends outwardly toward ends of the compressible electrical contact, wherein in a substantially compressed state, each pair of opposing inner surfaces collapses inwardly to form a tapered slot, and wherein the plurality of divaricated-cut sections is included in a medial portion.

2 . The compressible electrical contact of claim 1 , wherein the compressible electrical contact is manufactured from a tube.

3 . The compressible electrical contact of claim 2 , wherein the tube comprises a material selected from the group consisting of brass, copper, beryllium copper, and stainless steel.

4 . The compressible electrical contact of claim 1 , wherein the at least one of the plurality of divaricated-cut sections is based on at least one divaricating pattern.

5 . The compressible electrical contact of claim 4 , wherein the at least one divaricating pattern comprises an upper tapered section and a lower tapered section.

6 . The compressible electrical contact of claim 1 , wherein the medial portion is disposed between the first contact end and the second contact end.

7 . The compressible electrical contact of claim 6 , wherein the plurality of divaricated-cut sections comprises a plurality of inner divaricated-cut sections disposed between the first contact end and the second contact end.

8 . The compressible electrical contact of claim 5 , wherein the medial portion comprises a plurality of medial elements, and wherein at least some of the plurality of medial elements are adjacent to the divaricated-cut sections.

9 . The compressible electrical contact of claim 1 , wherein the at least one cut angle is about 5 degrees.

10 . The compressible electrical contact of claim 1 , wherein the outermost cut distance is about 0.002 inches.

11 . The compressible electrical contact of claim 1 , wherein the innermost cut distance is about 0.001 inches.

12 . The compressible electrical contact of claim 1 , wherein the plurality of divaricated-cut sections comprises a first end cut positioned adjacent to the first contact end.

13 . The compressible electrical contact of claim 12 , wherein the plurality of divaricated-cut sections comprises a second end cut, opposing the first end cut, positioned adjacent to the second contact end.

14 . The compressible electrical contact of claim 1 , wherein the compressible electrical contact has an effective outer diameter of about 0.010 inches.

15 . A compressible electrical contact, comprising:
a first contact end; a second contact end opposing the first contact end; and a plurality of divaricated-cut sections positioned between the first contact end and the second contact end, each of the plurality of divaricated-cut sections being defined by at least two cut angles measured between pairs of outwardly extending opposing inner surfaces, an innermost cut distance, and an outermost cut distance, wherein the innermost cut distance is smaller than the outermost cut distance, wherein in a substantially relaxed state, each pair of opposing inner surfaces extends outwardly toward ends of the compressible electrical contact, and wherein in a substantially compressed state, each pair of opposing inner surfaces collapses inwardly to form a tapered slot.

16 . The compressible electrical contact of claim 15 , wherein the compressible electrical contact is manufactured from a tube.

17 . The compressible electrical contact of claim 15 , wherein the at least one of the plurality of divaricated-cut sections is based on at least one divaricating pattern.

18 . The compressible electrical contact of claim 17 , wherein the at least one divaricating pattern comprises an upper tapered section and a lower tapered section.

19 . The compressible electrical contact of claim 15 , wherein the plurality of divaricated-cut sections is included in a medial portion disposed between the first contact end and the second contact end.

20 . The compressible electrical contact of claim 15 , wherein the upper cut angle is about 5 degrees.

21 . The compressible electrical contact of claim 15 , wherein the outermost cut distance is about 0.002 inches.

22 . The compressible electrical contact of claim 15 , wherein the innermost cut distance is about 0.0006 inches.
