A backplane electrical connector electrically and physically connects a daughter card printed circuit board to a backplane printed circuit board. The electrical connect can be of a two-piece construction including a daughtercard connector mateable with a pin header. The daughtercard connector can be assembled from a plurality of wafers which each can include a plurality of conductive leads. The wafers can have an attachment edge that lies adjacent to the daughtercard and a mating edge that is directed toward the pin header. Each conductive lead can include a bifurcated contact extending from the mating edge and each can have a first arm and a second arm. The first and second arms can provide two redundant points of contact with a corresponding conductive pin disposed in the pin header.

We claim: 1. An electrical connector assembly comprising: a pin header adapted to be mounted to a backplane board, said pin header including an insulative body and a plurality of conductive pins retained in and projecting from said insulative body, said plurality of pins arranged in rows and columns, each of the plurality of pins having a first side facing a first direction; and a daughter card connector mateable with said pin header, said daughter card connector including a mating face and a plurality of conductive leads extending through said daughter card connector, said contact leads including first and second arms extending in parallel relation to each other, said second arm having an “L” shaped terminal end with a portion extending transversely to the first arm, the first arm having a first contact protuberance and the second arm having a second contact protuberance, the first and second contact protuberance configured to engage the first side of the pins in the pin header. 2. The electrical connector of claim 1, in which said first arm extends a first distance from the mating face and said second arm extends a second distance from the mating face, said first distance being less than said second distance. 3. The electrical connector of claim 2, in which said first arm includes a first contact protuberance and said second contact arm includes a second contact protuberance, the second contact protuberance being spaced apart from said second contact arm and linearly aligned with the first contact protuberance. 4. The electrical connector of claim 1, in which said daughter card connector is comprised of a plurality of wafers, each wafer retaining a plurality of said adjacent conductive leads. 5. The electrical connector of claim 4, in which said conductive leads are formed from a conductive sheet material. 6. The electrical connector of claim 1, in which said plurality of conductive leads includes at least one ground contact lead and at least one differential signal pair of contact leads. 7. The connector of claim 1, wherein the plurality of conductive leads comprises first contact leads and second contact leads, the first contact leads extending a different distance than the second contact leads, wherein the contact protuberances are configured to provide at least three different points of engagement with the pins in the pin header. 8. A stamped lead frame of conductive material comprising: a plurality of conductive leads, each said conductive lead having a complaint terminal at a first end, a bifurcated contact at a second end, and a conductive portion extending between the complaint terminal and the bifurcated contact, said conductive leads being arranged in a co-planar, parallel and spaced relationship; said bifurcated contact includes a first cantilevered arm with a first contact protuberance and a second cantilevered “L” shaped arm with a second contact protuberance, said first cantilevered arm and a main linear extension of said second “L” shaped arm being joined to and extending from the conductive portion in a co-planar, spaced apart relation and the first and second contact protuberances being configured to engage a mating pin on a first side. 9. The stamped lead frame of claim 8, in which said first arm has a first length and said second arm has a second length greater than said first length. 10. The stamped lead frame of claim 9, in which said second “L” shaped arm extends back toward said first cantilevered arm in the configuration of a hook, but is spaced apart from said first cantilevered arm. 11. An electrical connector comprising: a plurality of conductive leads adjacently arranged in at least one or more columns, said leads each including a bifurcated contact extending generally perpendicularly through a mating face of the connector, said bifurcated contacts each including a first arm extending from the mating face a first distance and having a first contact protuberance and a second arm extending from the mating face a second distance longer than the first distance and having a second contact protuberance, said first and second arms being co-planar to an imaginary plane oriented normal to the mating face, said first contact arm being disposed in a recess delineated by said second contact arm and configured to sequentially engage a first side of a mating pin with the first contact protuberance and the second contact protuberance. 12. The electrical connector of claim 11, in which the distal end of said first arm includes a first contact protrusion and the distal end of said second arm includes a second contact, said first and second contact protrusions linearly aligned along an imaginary line oriented normal to the mating face. 13. The electrical connector of claim 12, further comprising at least one wafer, said wafer including an insulative support frame, said columns of conductive leads being disposed in said insulative support frame. 14. The electrical connector of claim 13, in which said wafer includes a first side and an opposing second side, the mating edge extending orthogonally between said first and second sides. 15. The electrical connector of claim 14, in which said first and second contact protuberances are directed toward the first side of said wafer.
