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.

We claim: 1. A connector comprising: an insulative cover member, the cover member including a front mating face and an open rear face; a plurality of connector units coupled to the cover member, each connector unit including an insulative support frame supporting a plurality of conductive terminals
We claim: 1. A connector comprising: an insulative cover member, the cover member including a front mating face and an open rear face; a plurality of connector units coupled to the cover member, each connector unit including an insulative support frame supporting a plurality of conductive terminals in two, spaced-apart columns of terminals, the support frame including a plurality of spoke members extending radially within the support frame from a front corner of the frame, the support frame further being formed from first and second support frame halves, separate from the cover member which holds the connector units, a single column of the terminals being supported by each of the first and second support frame halves, the first and second support frame halves spacing the two terminal columns apart from each other, widthwise, within each of the connector units; each of the terminals including tail portions for mounting to a circuit board, contact portions for mating with an opposing connector and body portions interconnecting the terminal tail and contact portions together, the terminals including distinct signal terminals and ground shield terminals, the signal terminals being aligned edge-to-edge to form differential signal terminal pairs within their respective terminal body portions within each of the two columns, the differential signal terminal pairs being separated from each other within a column by a single ground shield terminal, the ground shield terminals being alternatingly spaced apart within the columns such that the ground shield terminals in each column are spaced apart from and face a differential signal terminal pair of an opposing column, each of said ground shield terminals being wider than the differential signal terminal pair within the connector unit; and respective columns of the terminals being attached to the connector unit along the spoke members of respective first and second support frame halves, the ground shield terminals of the first support frame half including open windows formed in their body portions, the windows being filled with material of the spoke members of one of the first support frame half for attachment to the differential signal pairs of terminals of the second support frame half facing the ground shield terminals of the first support frame half being narrowed in their widths proximate to the windows so as to increase edge-to-edge spacing between the differential signal terminal pair in order to decrease broadside coupling between the differential signal terminal pairs and the ground shield terminals and to control edge coupling between the differential signal terminal pair. 2. The connector of claim 1, wherein the spoke members include interior spoke portions on one of the frame halves, the interior spoke portions extending across open, interior surfaces of the first support frame half terminals. 3. The connector of claim 2, wherein one of the interior spoke portions bisects the frame half. 4. The connector of claim 2, wherein the interior spoke portion define two V-shaped channels on an inner face of the one frame half. 5.

The connector of claim 1, wherein the narrowed differential signal terminal portions begin and end within an area defined by edges of the ground shield terminal windows. 7. The connector of claim 1, wherein some of the ground shield terminals are narrowed proximate to the windows. 8. The connector of claim 1, wherein one of the frame halves includes a plurality of engagement posts projecting therefrom, each of the posts being located proximate to the differential signal terminal narrowed edge portions. 9. The connector of claim 8, wherein the other of the frame halves includes a plurality of recesses for receiving the engagement posts, the recesses being disposed within the ground shield terminal windows. 10. The connector of claim 2, wherein the interior spoke portions serve to space apart the terminal columns. 11. A high speed differential signal connector, comprising: a plurality of connector units, each connector unit including a first and second subunit, the first and second subunit each including a plurality of conductive terminals arranged in a linear array, such that each of the connector units includes a first terminal array and a second terminal array spaced apart from each other, the first terminal array being supported by the first subunit and the second terminal array being supported by the second subunit, wherein the terminals are arranged within each terminal array as distinct pairs of differential signal terminals with a ground shield terminal interposed between the pair of differential signal terminals, the terminals of the two terminal array being arranged such that each ground shield terminal of the first terminal array opposes a differential signal terminal pair in the second terminal array and each ground shield terminal of the second terminal array opposes a differential signal terminal pair in the first terminal array; first and second spoke provided in each of in the first and second subunit, the first and second spoke of the first subunit extending along only an outer side of the first terminal array and the first and second spoke of the second subunit extending along an opposing outer side and an inner side of the second terminal array, the first and second spoke supporting the corresponding terminal arrays; and openings in the ground shield terminals formed and aligned with the spokes, wherein the pairs of differential signal terminals have reduced width portions disposed therein adjacent to and in opposition to the openings in the ground shield terminals. 12. The connector of claim 11, wherein the first and second spokes extend linearly within the first and second connector subunits. 13. The connector of claim 11, wherein the first and second spokes extend in a radial direction within the first and second connector subunits. 14. The connector of claim 11, wherein the second spoke extends along a line defined by selected ground shield terminal openings. 15. The connector of claim 11, wherein the second spoke extends through the ground shield terminal openings of the second terminal array. 16. The connector of claim 11, wherein the first and second spoke of the second subunit space the first and second terminal array apart from each other. 17. The connector of claim 11, wherein the first and second terminal array both include a column of terminals.
