Abstract
An electrical connector assembly is provided including a plurality of wafers having ground and signal traces with the signal traces being arranged in differential pairs, a first connector housing including channels adapted to retain a first group of wafers, and a second connector housing including channels adapted to retain a second group of wafers. The electrical connector assembly also includes signal contacts joining the differential pairs of the signal traces on the first group of wafers with corresponding differential pairs of the signal traces on the second group of wafers. The first and second connector housings join the first group of wafers in a non-parallel relationship to the second group of wafers.
Claims25
An electrical connector assembly comprising:
- wafers having arranged in at least one differential pair on each of at least first and second wafers;
- a first connector housing retaining a first group of wafers;
- a second connector housing retaining a second group of wafers;
- and
- signal contacts joining said differential pairs of said signal traces on said first wafer with a corresponding differential pairs of said signal traces on said second wafer said first and second connector housing joining said first group of wafers in a non-parallel relationship to said second group of wafers.
An electrical connector assembly comprising:
- first and second wafers each having signal traces arranged in differential pairs;
- a first connector housing adapted to retain said first wafer;
- a second connector housing adapted to retain said second wafer;
- and
- signal contacts joining at least one differential pairs of said signal traces on said first wafer with a corresponding differential pair of said signal traces on said second wafer, said first and second connector housings joining said first wafer in a non-parallel relationship to said second wafer.
An electrical connector assembly comprising:
- a plurality of wafers having ground and signal traces, said signal traces being arranged in differential pairs;
- a first connector housing including channels adapted to retain a first group of wafers;
- a second connector housing including channels adapted to retain a second group of wafers;
- a wafer interface secured to one of said first and second connector housings, said wafer interface including cavities;
- ground and signal contacts loaded into said cavities for connection to corresponding ground and signal traces, said signal contacts being arranged in differential pairs with corresponding ground contacts located therebetween along a first axis, each ground contact and signal contact including ground beams and signal beams, respectively, each ground beam being located immediately adjacent and facing a corresponding signal beam;
- and
- said wafer interface holding said signal beams in a biased state to deflect said signal beams away from corresponding ground beams to define gaps therebetween.
An electrical wafer configuration for carrying differential pairs of signals, comprising:
- a first wafer having a differential pair of signal traces thereon;
- a second wafer having a differential pair of signal traces thereon, said first and second wafers being joined in a non-parallel relationship with one another;
- and
- signal contacts joining said differential pair of signal traces on said first wafer with said differential pair of signal traces on said second wafer.
