Abstract
A high speed electrical connector configured to reduce the incidence of cross-talk is disclosed. The connector includes a connector housing and a plurality of columns of differential contact pairs and ground contacts. Each column of differential contact pairs and ground contacts is offset from an adjacent column such that multi-active cross-talk is reduced with respect to each differential contact pair.
Claims22
An electrical connector comprising:
- a connector housing;
- a plurality of columns of differential contact pairs disposed within the housing, each differential contact pair including a first signal contact for transmitting a signal having a first polarity and a second signal contact for transmitting a signal having a second polarity, opposite to said first polarity;
- and
- a plurality of ground contacts wherein a ground contact is disposed between each differential contact pair within each column of differential contact pairs;
- wherein each column of differential contact pairs and ground contacts is offset from an adjacent column such that multi-active cross-talk is reduced with respect to each differential contact pair.
