Abstract

An electrical contact for use in connecting electrical wires is disclosed. The electrical contact includes a cage-like structure, a wire connecting portion, and a flexing contact portion. The cage-like structure includes a plurality of sidewalls and is configured to receive a wire. The wire connecting contact portion includes at least two contact tines that are configured to conductively couple with a corresponding wire. The flexing contact portion includes an end wall, an elastic portion, an extension portion, and a nose portion. The flexing contact portion can store elastic energy and apply a force to a corresponding electrical component.

First claim

What is claimed is:

1. An electrical contact comprising:
a cage-like structure comprising a plurality of sidewalls, the plurality of sidewalls defining a wire inlet at a proximal end of the electrical contact;
a wire connecting portion coupled to the cage-like structure, the wire connecting portion comprising:
a first contact tine extending from a first sidewall of the plurality of sidewalls;
a second contact tine extending from a second sidewall of the plurality of sidewalls, wherein a pinch-point is created between the first contact tine and the second contact tine; and

a flexing contact portion coupled to the wire connecting portion, the flexing contact portion comprising:
an end wall at a distal end of the electrical contact;
an elastic portion that extends from the end wall toward the proximal end; and
an extension portion that extends from the elastic portion.

2. The electrical contact of claim 1 , wherein the flexing contact portion further comprises a nose portion extending from a distal end of the extension portion.

3. The electrical contact of claim 2 , wherein the nose portion is gold-plated.

4. The electrical contact of claim 2 , wherein the nose portion extends from the extension portion at a different direction than a direction at which the extension portion extends from the elastic portion.

5. The electrical contact of claim 2 , wherein the nose portion extends from the extension portion toward the wire connecting portion.

6. The electrical contact of claim 2 , wherein the extension portion comprises a straight segment extending between the elastic portion and the nose portion.

7. The electrical contact of claim 1 , wherein the elastic portion comprises a curved portion between the end wall and the extension portion.

8. The electrical contact of claim 1 , wherein the elastic portion and the extension portion are cantilevered from the end wall.

9. The electrical contact of claim 8 , wherein at least a portion of the extension portion is cantilevered over the wire connecting portion.

10. The electrical contact of claim 1 , wherein a width of the end wall is greater than a width of the elastic portion and the extension portion.

11. The electrical contact of claim 1 , wherein the electrical contact consists of a single conductive element.

12. The electrical contact of claim 1 , further comprising a base portion shared by the cage-like structure and the wire connecting portion, wherein the base portion comprises at least one of the pluralities of sidewalls of the cage-like structure and connects to the end wall of the flexing contact portion.

13. The electrical contact of claim 12 , wherein the end wall is perpendicular to the base portion.

14. A system comprising:
an electrical contact comprising:
a cage-like structure comprising a plurality of sidewalls, the plurality of sidewalls defining a wire inlet at a proximal end of the electrical contact;
a wire connecting portion comprising:
a first contact tine extending from a first sidewall of the plurality of sidewalls;
a second contact tine extending from a second sidewall of the plurality of sidewalls, wherein a pinch-point is created between the first contact tine and the second contact tine; and

a flexing contact portion comprising:
an end wall at a distal end of the electrical contact;
an elastic portion that extends from the end wall toward the proximal end; and
an extension portion that extends from the flexing portion;

a printed circuit board connected to the electrical contact, wherein at least one sidewall is mounted to the board; and
an electrical component comprising a contact pad, wherein the flexing contact portion is conductively coupled to the contact pad.

15. A method comprising:
inserting a wire into a wire inlet opening at a proximal end of an electrical contact, wherein the electrical contact further comprises a flexing contact portion at a distal end opposite the proximal end;
extending a conductive core of the wire into a wire connecting portion of the electrical contact such that the conductive core of the wire is compressed between a first contact tine and a second contact tine of the electrical contact;
mounting the electrical contact on a printed circuit board; and
positioning the electrical contact adjacent a contact pad of an electrical component such that the flexing contact portion is conductively coupled to the contact pad and the contact pad is conductively coupled to the conductive core of the wire, wherein positioning the electrical contact comprises decreasing a distance between the printed circuit board and the electrical component to compress the flexing contact portion of the electrical contact.

16. The method of claim 15 , wherein the positioning of the electrical contact causes compression of the flexing contact portion of the electrical contact.

17. The method of claim 16 , wherein the positioning of the electrical contact causes a force to be exerted by the flexing contact portion on the contact pad.

18. The method of claim 15 , wherein the positioning of the electrical contact comprises compressing the electrical contact into a receptacle.

19. The method of claim 15 , wherein the positioning of the electrical contact comprises conductively coupling a nose portion of the flexing contact portion to the contact pad.
