Abstract

Claims (31)

1. An electrical connector comprising:

a back end sub-assembly including a back end housing extending along a longitudinal axis between a forward side and a rearward side, the back end housing defining a plurality of contact zones arranged in quadrants;

at least one contact held in each of the quadrants of the plurality of contact zones; and

an electrical shield provided within each of the plurality of contact zones, each shield at least partially surrounding the at least one contact in the corresponding contact zone, wherein each shield is non-common with and does not electrically engage any other shield in the back end housing.

2. The electrical connector of claim 1 , wherein each contact zone includes a single pair of contacts carrying differential signals.

3. The electrical connector of claim 1 , wherein each shield is arranged at least partially between the associated contact zone and at least two other contact zones.

4. The electrical connector of claim 1 , wherein each contact zone includes more than two contacts.

5. The electrical connector of claim 1 , wherein each quadrant contains a single contact zone, each shield being arranged between at least two adjacent quadrants.

6. The electrical connector of claim 1 , wherein each contact zone is separated from each other contact zone by at least two shields.

7. The electrical connector of claim 1 , wherein each shield is separated from each other shield by a dielectric barrier.

8. The electrical connector of claim 1 , wherein the back end housing includes a plurality of shield channels, each shield being received in a corresponding shield channel.

9. The electrical connector of claim 1 , wherein each shield is securely held by the back end housing.

10. The electrical connector of claim 1 , wherein the contacts extend along a contact axis, the contacts are arranged in the corresponding contact zone such that the contact axes of contacts in adjacent contact zones are aligned in a contact plane, wherein at least one shield extends along and within the contact plane.

11. The electrical connector of claim 10 , wherein each shield includes a wing extending outward therefrom, the wing extending along and within the contact plane.

12. The electrical connector of claim 1 , wherein each shield extends proximate to an external side of the back end housing to provide shielding for at least one of the contacts from alien cross-talk.

13. An electrical connector comprising:

a housing having a forward mating end and an opposite rearward cable receiving end;

a connector assembly having an array of mating contacts arranged within the housing at the forward mating end for mating engagement with a mating connector;

a back end sub-assembly held in the housing proximate the cable receiving end, the back end sub-assembly including a back end housing extending along a longitudinal axis between a forward side and a rearward side, the back end housing being configured to receive individual wires of a multi-wire cable through the rearward side, the back end housing defining a plurality of contact zones;

a pair of back end contacts held in each contact zone, the back end contacts being discrete from the mating contacts and being electrically connected to corresponding mating contacts of the connector assembly, each of the back end contacts being electrically connected to corresponding wires of the multi-wire cable; and

a conductive shield held in each contact zone, the shield positioned between the contacts in the corresponding contact zone and at least one contact in at least one other contact zone, wherein each shield is a floating shield that does not electrically engage any other shield in the back end housing.

14. The electrical connector of claim 13 , wherein the back end housing is arranged in quadrants, each quadrant containing a single contact zone, each shield being arranged between at least two adjacent quadrants.

15. The electrical connector of claim 13 , wherein each shield is separated from each other shield by a dielectric barrier.

16. The electrical connector of claim 13 , wherein the back end housing includes a plurality of shield channels, each shield being received in a corresponding shield channel.

17. An electrical connector comprising:

a housing having a forward mating end and an opposite rearward cable receiving end;

a back end sub-assembly held in the housing proximate the cable receiving end, the back end sub-assembly including a back end housing holding back end contacts and a conductive shield positioned between selected ones of the back end contacts, the back end housing extending along a longitudinal axis between a forward side and a rearward side, the back end housing including an alignment member extending toward the cable receiving end of the housing; and

a lacing cap attached to the cable receiving end of the housing, the lacing cap configured to receive a multi-wire cable and including lacing stations configured for holding the individual wires of the multi-wire cable to terminate to the back end contacts, the lacing cap including an alignment slot that receives the alignment member to align the lacing stations with the back end contacts.

18. The electrical connector of claim 17 , wherein the alignment member is centrally positioned between opposite sides of the back end housing.

19. The electrical connector of claim 17 , wherein the back end housing defines a plurality of contact zones and the alignment member is positioned between an adjacent pair of contact zones.

20. The electrical connector of claim 17 , wherein the alignment slot is formed between adjacent lacing stations.
