Electrical connector

1. A connector, comprising:

a housing having a mating face and a mounting face;

a plurality of wafers disposed within the housing;

a plurality of ground and signal conductive terminals being supported by the plurality of wafers, each of the terminals including a contact portion disposed at one end, a tail portions disposed at an opposite end thereof and a body portion interconnecting the contact and tail portions together, each of the wafers defining a frame that supports a respective set of terminals; and

a first of the plurality of wafers supporting a plurality of ground terminals and a second of the plurality of wafers supporting a plurality of first signal terminals and a third of the plurality of wafers supporting a plurality of second signal terminals, the first and second signal terminals having body portions having substantially a first width and the ground terminals having a body portion with a second width that is greater than the first width substantially the entire length of the body portion of the ground terminal, the second and third wafers being disposed adjacent each other such that the first and second signal terminals face each other and are broadside coupled together so as to carry differential signals thereacross, wherein the first wafer is disposed adjacent the second wafer.

2. The connector of claim 1 , wherein at least one of the ground terminals in the first wafer includes at least one notch to facilitate the over molding of the first wafer over the ground terminals.

3. The connector of claim 1 , wherein the second and third wafers include channels disposed therein that extend widthwise through the second and third wafers, thereby creating horizontal air pockets within the wafers that separate differential signal pairs within the second and third wafers.

4. An electrical connector, comprising:

a housing including a mating face and a mounting face, the mating face including two slots, each of the slots configured to receive an edge of a circuit card from an opposing, mating connector, the mounting face configured for press fit termination to a circuit board;

a plurality of pairs of signal wafers positioned adjacent one another in the housing, each of the signal wafers including a plurality of conductive signal terminals supported thereby for position within the respective edge-card receiving slot, each signal terminal including a contact, a tail and a body with a first width extending therebetween, each signal wafer including a mating edge having four contacts extending therefrom proximate to the housing mating face, the four contacts directed to opposite sides of the respective slots, and each of the signal wafers further including a mounting edge having a row of tails extending therefrom;

a plurality of ground wafers each including a plurality of conductive ground terminals supported thereby, each ground terminal including a contact, a tail and a body with a minimum width extending therebetween, each ground wafer further including a mating edge having four contacts extending therefrom proximate to the housing mating face and on opposite sides of the slots, and a mounting edge having a row of tails extending therefrom,

one ground wafer being associated with each pair of signal wafers, wherein first width is less than the minimum width, some of the ground terminal body portions having angled parts.

5. The connector of claim 4 , wherein for each pair of adjacent signal wafers, the signal terminals are aligned with each other in a broadside fashion from the housing mating face to proximate the housing mounting face.

6. The connector of claim 4 , wherein at least one of the ground terminals has no ground terminal notches.
