Abstract

A self-aligning electrical connector for providing electrical communication between two electrical devices includes an electrical contact. A terminal system is resiliently coupled to the electrical contact by a resilient frame. The resilient frame is capable of allowing the electrical contact to move relative to the terminal system along X and Y axes.

1. A self aligning electrical connector for providing electrical communication between two electrical devices comprising:

an electrical contact; and

a terminal system resiliently coupled to the electrical contact by a resilient frame, the resilient frame having a planar portion from which the electrical contact extends with a vertical side wall extending from the planar portion, and a resilient beam extending from the side wall, the resilient frame capable of allowing the electrical contact to move relative to the terminal system along X and Y axes.

2. The connector of claim 1 in which the terminal system comprises two terminal pins.

3. The connector of claim 2 in which the resilient frame comprises two resilient beams each resiliently coupled between a respective terminal pin and the electrical contact.

4. The connector of claim 3 in which each terminal pin extends downwardly from a respective resilient beam.

6. The connector of claim 5 in which the proximal beam portion and the distal beam portion are formed at right angles relative to each other.

7. The connector of claim 6 in which the electrical contact comprises two opposing grippable contact tabs angled upwardly and separated by a gap, the contact tabs capable of deflecting upwardly.

8. The connector of claim 7 in which the contact tabs each have two pointed contact tips.

9. The connector of claim 1 in which the side wall is one of a pair of vertical side walls extending upwardly from opposite edges of the planar portion, and the resilient beam is one of two resilient beams extending from at least one side wall.

10. The connector of claim 9 in which the planar portion is capable of resiliently bowing upwardly and the side walls are capable of resiliently twisting when the contact tabs are resiliently deflected upwardly.

11. The connector of claim 10 in which a portion of the resilient beams extend over the planar portion, thereby limiting the amount of bowing of the planar portion.

12. A self-aligning electrical connector for providing electrical communication between two electrical devices comprising:

a planar portion having edges;

an electrical contact extending from the planar portion, the electrical contact comprising two opposed contact tabs located between two openings in the planar portion, the contact tabs being angled upwardly and separated by a gap;
