Abstract

An orthogonal electrical connector system includes vertical electrical connectors that are configured to be mated to each other so as to place respective pluralities of first and second substrates that are oriented orthogonal to each other in data communication with each other through the mated electrical connectors. Other connector systems are also disclosed.

First claim

What is claimed is:

1. An electrical cable connector comprising:
electrical contacts not defined as PCB pads or PCB contacts, wherein the electrical contacts comprise a plurality of signal contacts that are arranged along respective columns that extend in a transverse direction; and
a connector housing that supports the electrical contacts, wherein the connector housing does not contain or receive an edge card;
a twin axial cable electrically connected to respective ones of the electrical contacts; and
a ground plate that includes a plate body and a plurality of ground mating ends and ground mounting ends that extend out from the plate body, wherein the plate body, the ground mating ends, and the ground mounting ends are all monolithic with each other,
wherein the ground plate defines a plurality of recessed regions that are recessed into the plate body along a lateral direction that is perpendicular to the transverse direction, respective ones of the recessed regions being aligned with respective pairs of mating ends of the signal contacts along the lateral direction, and
wherein the electrical cable connector is configured to transmit electrical signals at data transfer speeds of 56 gigabits/sec NRZ or 112 gigabits/sec PAM-4 signaling.

2. The electrical cable connector as recited in claim 1 , wherein the twin axial cable is devoid of drains.

3. The electrical cable connector as recited in claim 2 , wherein the ground plate comprises a plurality of ground plates, the signal contacts are arranged along respective columns that extend in a transverse direction, and columns of mounting ends of the signal contacts are aligned with the ground mounting ends of respective ones of the plurality of ground plates along the transverse direction.

4. The electrical cable connector as recited in claim 2 , wherein the recessed regions are spaced from each other along the transverse direction.

5. The electrical cable connector as recited in claim 2 , wherein the respective pairs of mating ends of the signal contacts face the respective ones of the recessed regions along the lateral direction, such that the mating ends of the signal contacts can flex toward the recessed regions, respectively, without contacting the ground plate when the electrical cable connector mates with a complementary electrical connector.

6. The electrical cable connector as recited in claim 1 , wherein the electrical contacts are arranged in two or more linear arrays.

7. The electrical cable connector as recited in claim 6 , wherein the electrical contacts are arranged in three or more linear arrays.

8. The electrical cable connector as recited in claim 1 , wherein the electrical contacts include electrical signal contacts and electrical grounds.

9. The electrical cable connector as recited in claim 8 , configured to produce a differential insertion loss between 0 dB and −1 dB when transmitting electrical signals along the signal contacts at all frequencies up to 27 GHz.

10. The electrical cable connector as recited in claim 8 , configured to produce a differential insertion loss between 0 dB and −2 dB while transferring electrical signals along the signal contacts at all data transfer frequencies up to 45 GHz.

11. The electrical cable connector as recited in claim 8 , wherein a differential TDR at 17 picosecond rise time (10% to 90%) has an impedance confined between 85 and 100 Ohms at all times from 0 picoseconds to 200 picoseconds.

12. The electrical cable connector as recited in claim 11 , wherein the ground plate comprises a plurality of ground plates, the signal contacts are arranged along respective columns that extend in a transverse direction, and columns of mounting ends of the signal contacts are aligned with the ground mounting ends of respective ones of the plurality of ground plates along the transverse direction.

13. The electrical cable connector as recited in claim 11 , wherein the recessed regions are spaced from each other along the transverse direction.

14. The electrical cable connector as recited in claim 11 , wherein the respective pairs of mating ends of the signal contacts face the respective ones of the recessed regions along the lateral direction, such that the mating ends of the signal contacts are flexible toward the recessed regions, respectively, without contacting the ground plate when the electrical cable connector mates with a complementary electrical connector.

15. The electrical cable connector as recited in claim 8 , configured to produce differential near end cross talk (NEXT) between −40 dB and −100 dB when transferring electrical signals along the electrical signal contacts at all frequencies up to 35 GHz.

16. The electrical cable connector as recited in claim 8 , configured to produce differential near end cross talk (NEXT) between −30 dB and −100 dB at while transferring electrical signals along the electrical signal contacts at all frequencies between 35 GHz and 45 GHZ.

17. The electrical cable connector as recited in claim 8 , configured to produce differential far end cross talk (FEXT) between −40 dB and −100 dB when transferring electrical signals along the electrical signal contacts at all frequencies up to 30 GHz.

18. The electrical cable connector as recited in claim 8 , configured to produce differential far end cross talk (FEXT) between −30 dB and −100 dB at while transferring electrical signals along the electrical signal contacts at all frequencies up to 45 GHZ.
