Abstract

A connector can be provided that allows for improved route-out including straight-back routing. Signal and ground terminal tails can be arranged in a single row to help facilitate such functionality. A commoning member can connect ground tails to ground terminals. Consequentially, a connector with two vertically stacked card slots can be provided that allows for straight back routing of the signal traces in four layers while still providing a compact connector design.

First claim

We claim:

1. A connector, comprising:
a housing with a mating face and a mounting face; and
a ground wafer with a first frame that supports a plurality of ground terminals, the ground wafer supported by the housing, each of the plurality of ground terminals including a contact aligned with the mating face, the plurality of ground terminals electrically connected to a first junction aligned with the mounting face;
a signal wafer positioned in the housing adjacent the ground wafer, the signal wafer including a second frame that supports a plurality of signal terminals, each of the plurality of signal terminals having a contact that is aligned with the mating face and a tail aligned with the mounting face, the signal wafer including a ground tail with a second junction, the second junction aligned with the mounting face; and
a flat plate positioned in the first and second junction.

2. The connector of claim 1 , wherein the ground wafer and the signal wafer define a channel and the flat plate is positioned in the channel.

3. The connector of claim 1 , wherein the flat plate is vertically aligned.

4. The connector of claim 3 , wherein the flat plate extends to an edge of the supporting frames.

5. The connector of claim 1 , wherein the signal terminals each include a body that extends from the tail to the contact, the body extending vertically past the flat plate and then extending transverse to the flat plate.

6. The connector of claim 1 , wherein the plurality of ground terminals are connected to an end and the first junction is a plurality of first junctions, each of the plurality of first junctions positioned in the end.

7. The connector of claim 6 , wherein the signal wafer supports a plurality of ground tails and each ground tail includes a second junction, wherein a plurality of flat plates connect the plurality of first junctions to the corresponding second junctions.

8. A method, comprising:
providing a connector with a mounting face and a mating face, the mating face including contacts for mating to another connector and the mounting face including tails for mating with a circuit board, the mounting face including a plurality of rows of channels, each of the plurality of rows of channels including a first junction and a second junction, the first junction connected to a ground tail and the second junction connected to a ground terminal; and
inserting a commoning member into each of the plurality of rows of channels, the commoning member electrically connecting the ground terminal to the ground tail.

9. The method of claim 8 , wherein the commoning member is a flat plate.

10. The method of claim 9 , wherein the first and second junctions are slots and the inserting step slides the flat plate into the corresponding slots.

11. The method of claim 8 , further comprising the step of mounting the connector on a circuit board.

12. The method of claim 8 , wherein the tails are press-fit tails and the step of mounting the connector on the circuit board include inserting the tails into vias on the circuit board.
