Abstract

A socket contact having a mating portion, a crimp portion, and a transition region connecting the mating portion with the crimp portion. The mating portion includes a top wall and a bottom wall joined by two opposing sidewalls, wherein the top, bottom and two opposing sidewalls forming a contact box open at, at least one end and configured to accept a pin contact. The contact box includes a first contact beam and a second contact beam. Each of the first contact beam and second contact beam includes a free end and a fixed end. The free end has a plurality of contact fingers. Each of the first contact beam and the second contact beam has a plurality of contact points.

Claims

1. A socket contact comprising:

a mating portion, a crimp portion, and a transition region connecting the mating portion with the crimp portion, the mating portion comprising;

a top wall and a bottom wall joined by two opposing sidewalls, wherein the top, bottom and two opposing sidewalls form a contact box with at least one open end, the contact box being configured to accept a mating pin contact through the open end;

the contact box comprises a first contact beam and a second contact beam, each of the first contact beam and second contact beam having a free end and a fixed end, the free end comprising a plurality of contact fingers,

the first contact beam having its fixed end located proximate an end of the contact box which is opposite the open end of the contact box,

wherein each of the first contact beam and the second contact beam having a plurality of contact points.

2. The socket contact of claim 1, wherein the contact fingers each comprise at least one contact point.

3. The socket contact of claim 1, wherein each of the first contact beam and second contact beam comprise at least three contact points.

4. The socket contact of claim 1, wherein the contact points are arranged and disposed to physically contact a pin contact positioned within the contact box at up to six points.

5. The socket contact of claim 1, wherein the first contact beam is cantilevered to provide reduced pin contact insertion force.

6. The socket contact of claim 1, wherein the second contact beam is cantilevered to provide pin contact stability.

7. The socket contact of claim 1, wherein the contact fingers are flexible.

8. The socket contact of claim 1, wherein the first or second contact beam comprises an embossment rib for achieving a predetermined beam stiffness and normal force.

9. The socket contact of claim 1, wherein the contact box comprises an opening configured to project a light beam through the opening to determine a separation distance between the first contact beam and the second contact beam.

10. An electrical connection system comprising:

a socket contact having a mating portion, a crimp portion, and a transition region connecting the mating portion with the crimp portion, the mating portion comprising;

a top wall and a bottom wall joined by two opposing sidewalls, wherein the top, bottom and two opposing sidewalls form a contact box, the contact box having at least one open end, the contact box being configured to accept a pin contact through the open end;

the contact box comprises a first contact beam and a second contact beam, each of the first contact beam and second contact beam having a free end, the free end and a fixed end comprising a plurality of contact fingers,

the first contact beam having its fixed end located proximate an end of the contact box which is opposite the open end of the contact box;

wherein each of the first contact beam and the second contact beam having a plurality of contact points; and

the pin contact inserted into the contact box, the pin contact being in physical contact with each of the contact points.

11. The electrical connection system of claim 10, wherein the contact fingers each comprise at least one contact point.

12. The electrical connection system of claim 10, wherein each of the first contact beam and second contact beam comprise at least three contact points.

13. The electrical connection system of claim 10, wherein the contact points are arranged and disposed to physically contact the pin contact at up to six points.

14. The electrical connection system of claim 10, wherein the first contact beam is cantilevered to provide reduced pin contact insertion force.

15. The electrical connection system of claim 10, wherein the second contact beam is cantilevered to provide pin contact stability.

16. The electrical connection system of claim 10, wherein the contact fingers are flexible.

17. The electrical connection system of claim 10, wherein the first or second contact beam comprises an embossment rib for achieving a predetermined beam stiffness and normal force.

18. The electrical connection system of claim 10, wherein the contact box comprises an opening configured to project a light beam through the opening to determine a separation distance between the first contact beam and the second contact beam.
