Abstract

An electrical connector for connecting a conductor of a daughter card connector wafer with a blade in the housing of a backplane connector. The daughter card conductor has a body with two elongated beams extending outward from the body. The two elongated beams each have an outer edge and an inner edge, whereby an opening is defined between the inner edges. The backplane conductor has a body with a narrowed tab portion extending outward from said second conductor body. The narrowed tab portion having outer opposite edges and is sized so that the narrowed tab portion fits between at least a portion of the outer edges of the two elongated beams, and in some cases between at least a portion of the inner edges of the two elongated beams.

First claim

The invention claimed is:

1. An electrical connector assembly comprising:
a first connector having a first conductor with a body and two elongated beams extending outward from said first conductor body, said two elongated beams each having an outer edge and a tip; and,
a second connector having a second conductor with a body having a top surface, a bottom surface, and a narrowed tab portion extending outward from said second conductor body, said narrowed tab portion having a top surface, a bottom surface and outer opposite side edges, wherein said narrowed tab portion fits between at least a portion of the outer side edges of said two elongated beams, and wherein the tips of said two elongated beams both contact the top surface of the body and/or tab portion.

2. The connector assembly of claim 1 , wherein said narrowed tab portion is substantially rectangular in shape.

3. The connector assembly of claim 1 , each of said two elongated beams further having an inner edge opposite the outer edge, wherein an opening is defined between the inner edges of the two elongated beams and said narrowed tab portion is received in at least a portion of said opening.

4. The connector assembly of claim 1 , each of said two elongated beams further having an inner edge opposite the outer edge, wherein an opening is defined between the inner edges of the two elongated beams and said narrowed tab portion is received in the entire said opening.

5. The connector assembly of claim 1 , each of said two elongated beams further having an inner edge opposite the outer edge, wherein said narrowed tab portion fits between at least a portion of the inner edges of said two elongated beams.

6. The connector assembly of claim 1 , each of said two elongated beams further having an inner edge opposite the outer edge, wherein said narrowed tab portion fits between the entire of the inner edges of said two elongated beams.

7. The connector assembly of claim 1 , each of said two elongated beams further having a central longitudinal axis, wherein said narrowed tab portion fits between at least a portion of the central longitudinal axes of said two elongated beams.

8. The connector assembly of claim 1 , each of said two elongated beams further having a central longitudinal axis, wherein said narrowed tab portion fits between the entire of the central longitudinal axes of said two elongated beams.

9. The connector assembly of claim 1 , wherein said two elongated beams have a proximal end connected to the first conductor body and a distal end connected to said second conductor and an intermediate portion therebetween.

10. The connector assembly of claim 9 , wherein said distal end is turned inward with respect to said intermediate portion.

11. The connector assembly of claim 9 , wherein said distal end comprises a bend section which is turned inward with respect to said intermediate portion, and a contact end which is turned outward with respect to said bend section, wherein said contact end has a tip that contacts said second conductor.

12. The connector assembly of claim 11 , wherein said tips of said two elongated beams are substantially parallel to the intermediate portions of said two elongated beams.

13. The connector assembly of claim 11 , wherein said tip is curved downward and transverse with respect to the inwardly turned bend section and said intermediate portion, said tip forming a contact point with said second conductor.

14. The connector assembly of claim 13 , wherein said second conductor has a half-circular cross-section.

15. The connector assembly of claim 11 , wherein the tips of said two elongated beams are narrower than the narrowed tab portion of said second conductor.

16. The connector assembly of claim 15 , wherein said tips are slidably engaged with said narrowed tab portion and said second conductor body.

17. The connector assembly of claim 1 , wherein said two elongated beams extend substantially perpendicular to said first conductor body.

18. The connector assembly of claim 1 , wherein said second conductor has a half-circular cross-section.

19. The connector assembly of claim 1 , wherein said narrowed tab portion fits between the entire outer edges of said two elongated beams.

20. The connector assembly of claim 1 , wherein said first conductor is substantially coplanar with said second conductor, and said first conductor has a distal end which connects to a major facing surface of said second conductor and a reverse bend which moves the distal end out of plane with the second conductor.

21. The connector assembly of claim 1 , wherein said first connector comprises a daughter card connector and said second connector comprises a backplane connector.

22. The connector assembly of claim 21 , wherein said first conductor comprises a wafer and said second conductor comprises a blade.

23. The connector assembly of claim 1 , wherein said first conductor has an intermediate portion which is at least partially embedded in an insulative housing.

24. The connector assembly of claim 1 , wherein said elongated beams arc coplanar.

25. The connector assembly of claim 1 , wherein said elongated beams are integrally formed from a same material.

26. The connector assembly of claim 1 , wherein the tips of said two elongated beams are substantially parallel to one another.

27. The connector assembly of claim 1 , wherein the tab portion has a flat rectangular shape.

28. The connector assembly of claim 1 , wherein said two elongated beams each have a longitudinal axis and extend downward with respect to the longitudinal axis and said second conductor.

29. An electrical connector assembly comprising:
a first connector having a first conductor with a body and two elongated beams extending outward from said first conductor body, said two elongated beams each having an outer edge, wherein said two elongated beams have a proximal end connected to the first conductor body and a distal end connected to said second conductor and an intermediate portion therebetween, further comprising a cross member connecting said distal ends of the two elongated beams; and
a second connector having a second conductor with a body and a narrowed tab portion extending outward from said second conductor body, said narrowed tab portion having outer opposite edges, wherein said narrowed tab portion fits between at least a portion of the outer edges of said two elongated beams.

30. An electrical connector comprising:
a first connector having a first conductor with a body and two elongated beams extending outward from said first conductor body, said two elongated beams each having an outer edge, an inner edge, and a tip, wherein the outer edges are separated by a first distance and an opening is defined between the inner edges of the two elongated beams; and,
a second connector having a second conductor with a body having a top surface and a bottom surface opposite the top surface, and a narrowed tab portion extending outward from said second conductor body, said narrowed tab portion having a top surface, a bottom surface opposite the top surface, and outer opposite side edges separated by a second distance, wherein the first distance is greater than the second distance and the tips of said two elongated beams both contact the top surface of the body and/or tab portion.
