Abstract

A connector system is disclosed that is configured to provide terminals that support data rates of 10 Gbps or more. Such a connector system includes a wafer set configured to enable broad-side coupling of a differential pair of terminals across an air channel formed between the terminals.

First claim

I claim:

1. A connector, comprising:
a first card slot, the card slot having a first side and a second side;
a wafer set having a first and second wafer, the first and second wafers being adjacent and each including an insulative frame and a first terminal with a contact, a tail and a body portion extending therebetween, the contacts being positioned in the first card slot on the first side, wherein the first terminals form a first differential pair, the body portions of the first terminals having lengthwise edges and being supported by the insulative frame of each respective terminal along the lengthwise edges of each respective terminal to produce an air channel, the body portions of the first terminals extending in substantial alignment from the contact to the tail of each respective terminal to enable broad-side coupling of the first differential pair across the air channel between the first terminals;
a first shield adjacent a first side of the wafer set, the first shield electrically coupled to a first ground contact and a first ground tail;
a second shield adjacent a second side of the wafer set, the second shield electrically coupled to a second ground contact and a second ground tail; and
a common bar that provides at least a portion of an electrical path between the first shield and the second shield.

2. The connector of claim 1 , wherein the first ground tail, the tails of the first terminals, and the second ground tail have a press-fit configuration.

3. The connector of claim 1 , wherein the first shield comprises a shield plate.

4. The connector of claim 1 , wherein the second shield comprises a shield plate.

5. The connector of claim 1 , wherein the body portions of the first terminals being supported by the insulative frame of each respective terminal along the lengthwise edges of each respective terminal comprises the body portions of the first terminals being supported by insert-molded insulative beams along the lengthwise edges of each respective terminal.

6. The connector of claim 1 , wherein the first and second wafers each include a second terminal with a contact, a tail and a body portion extending therebetween, the contacts being positioned in the first card slot on the second side and the second terminals being configured like the first terminals.

7. The connector of claim 1 , wherein the wafer set is a first wafer set, the connector further including a second wafer set configured like the first wafer set, the second wafer set have a third shield adjacent a first side and a fourth shield adjacent a second side.

8. The connector of claim 1 , wherein the connector includes a second card slot and the wafer set supports four differential pairs of terminals.

9. The connector of claim 1 , wherein the first terminals are configured to support a data rate of 10 Gbps in a non-return to zero (NRZ) encoding.

10. The connector of claim 1 , wherein the terminals in the card slot are on a 0.5 mm pitch.

11. The connector of claim 1 , wherein the first terminals, the first shield and the second shield are configured to enable the first terminals to be preferentially coupled together.

12. The connector of claim 1 , wherein the common bar is positioned in a groove of the first shield and in a groove of the second shield.

13. The connector of claim 1 , wherein the common bar is positioned in a slot of the first shield and in a slot of the second shield.

14. The connector of claim 1 , wherein the first shield is substantially parallel the first side of the wafer set, the second shield is substantially parallel the second side of the wafer set, and the common bar is transversely positioned with respect to both the first shield and the second shield.

15. The connector of claim 1 , further comprising a second common bar that provides at least a portion of an electrical path between the first shield and the second shield, wherein the common bar is a first common bar.

16. The connector of claim 1 , wherein the first common bar and the second common bar are positioned apart such that a portion of the first terminal of the first wafer and a portion of the first terminal of the second wafer each are between the first common bar and the second common bar.
