Claims
- 1. A connector assembly for use in connecting differential signal circuits on two different circuit boards together, comprising:
an insulative housing including a plurality of cavities defined in said housing, the cavities extending completely through said housing between opposite surfaces thereof; said housing having a conductive coating formed on at least some exterior surfaces thereof including on the surfaces of said plurality of cavities for providing a reference ground surrounding each of said cavities, said housing further including a plurality of ground terminal members associated therewith which are in electrical contact with said conductive exterior surfaces for electrically connecting said conductive surfaces to ground circuits on said circuit boards; and, a plurality of terminal assemblies received in said plurality of cavities, each of the terminal assemblies including at least one differential signal terminal pair, said at least one signal terminal pair including tail portions at each end of the terminal assembly for connecting the terminal pairs to circuits on said circuit boards, and intermediate portions which interconnect said tail portions together, said terminal assemblies being at least partially held within said cavities.
- 2 The connector assembly of claim 1, wherein said tail portions of each terminal pair are compliant.
- 3. The connector assembly of claim 1, wherein an insulative material is formed about said terminal pairs between the tail portions.
- 4. The connector assembly of claim 3, wherein recesses are defined in said insulative material along said terminal pairs to tune the high frequency impedance of the terminal pairs.
- 5. The connector assembly of claim 1, wherein said connector assembly is elongated, thereby defining a centerline along the length of said connector assembly and said cavities defined in the connector assembly in one surface thereof are elongated in a direction transverse to that of the centerline, and a plurality of smaller cavities are defined in an opposite surface of the connector assembly, said plurality of smaller cavities in communication with each of said elongated cavities to define a plurality of passages through said connector assembly.
- 6. The connector assembly of claim 5, wherein said terminal assemblies each comprise an insulative and elongated base portion adapted to fit into one of said elongated cavities and a plurality of insulative leg portions extending from each base portion adapted to fit into respective ones of said plurality of smaller cavities, with one terminal signal pair disposed in each of said leg portions and through the elongated base portion, said terminal pairs having tail portions extending from the leg portions and from the elongated base portion at opposite surfaces of said connector assembly.
- 7. A terminal assembly for use in a connector which connects circuits on two different circuit boards together, comprising:
an insulative base portion having a plurality of surfaces, one of the surfaces of the base portion defining a bottom surface of the terminal assembly; a plurality of leg portions extending from said base portion, one of the surfaces of the leg portions defining a top surface of the terminal assembly; at least one terminal disposed in each leg and extending through said base portion, the terminal having a body portion and two opposing compliant pin tail portions that projecting out from said terminal assembly top and bottom surfaces for mating with holes in said circuit boards.
- 8. The terminal assembly of claim 7, wherein said base portion includes a plurality of openings formed therein that expose said terminal body portions in order to define air gaps between said terminal body portions and a connector into which said terminal assembly is inserted.
- 9. The terminal assembly of claim 8, wherein said terminal assembly is formed from two interengaging halves, each of the two halves having engagement means for joining the two halves together into said terminal assembly.
