Flexing poke home contact
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.
1. An electrical contact comprising:
a wire inlet portion;
a wire connecting portion connected to the wire inlet portion, the wire connecting portion comprising a first contact tine and a second contact tine that define a pinch-point; and
a flexing contact portion connected to the wire connecting portion, the flexing contact portion comprising:
an end wall;
an elastic portion extending from the end wall toward the wire inlet portion; and
an extension portion extending from the elastic portion.
2. The electrical contact of claim 1 , wherein the flexing contact portion further comprises a nose portion extending from 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 an end of 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 extends 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 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 wire inlet portion and the wire connecting portion.
13. The electrical contact of claim 12 , wherein the wire inlet portion comprises a plurality of sidewalls, and wherein the base portion comprises at least one sidewall of the plurality of sidewalls.
14. The electrical contact of claim 13 , wherein the base portion connects to the end wall of the flexing contact portion.
15. The electrical contact of claim 12 , wherein the end wall is perpendicular to the base portion.
16. The electrical contact of claim 1 , wherein the wire inlet portion is located at a first end of the electrical contact, wherein the end wall is located at a second end of the electrical contact, and wherein the elastic portion extends from the second end toward the first end.
17. The electrical contact of claim 1 , wherein the wire inlet portion comprises a first sidewall and a second sidewall, wherein the first contact tine extends from the first sidewall, and wherein the second contact tine extends from the second sidewall.
18. A system comprising:
an electrical contact comprising:
a wire inlet portion;
a wire connecting portion comprising:
a first contact tine extending from the wire inlet portion; and
a second contact tine extending from the wire inlet portion to define a pinch-point between the first contact tine and the second contact tine; and
a flexing contact portion connected to the wire connecting portion, wherein the flexing contact portion comprises an extension portion that is cantilevered over at least a portion of the wire connecting portion;
a printed circuit board connected to the electrical contact; and
an electrical component comprising a contact pad, wherein the flexing contact portion is conductively coupled to the contact pad.
19. The system of claim 18 , wherein the flexing contact portion further comprises:
an end wall;
an elastic portion extending from the end wall; and
a nose portion extending from the extension portion, wherein the extension portion extends from the elastic portion and creates a force compressing the nose portion against the contact pad.
20. The system of claim 18 , further comprising a wire positioned within the wire inlet portion, wherein the wire includes a conductive core that is electrically coupled to the first contact tine and the second contact tine.
