ABSTRACT:
A high speed connector with reduced crosstalk utilizes individual connector support frames that are assembled together to form a block of connector units. Each such unit supports a column of conductive terminals in two spaced-apart columns. The columns have differential signal terminal pairs separated from each other by larger intervening ground shields that serve as ground terminals. The ground shields are arranged in alternating fashion within the pair of columns and they are closely spaced together so as to face a differential signal terminal pair. In areas where the terminals are mounted to the connector units, window-like openings are formed in the large ground shield terminals to reduce the amount of broadside coupling between the differential signal terminal pair and the signal terminal pair are narrowed to increase their edge-to-edge distance to account for the change in dielectric constant of the connector unit material filing in the area between the signal terminal pair.
