Abstract

A modular electrical connector with separately shielded signal conductor pairs. The connector may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. Modules of different sizes may be assembled into wafers, which are then assembled into a connector. Wafers may include lossy material. In some embodiments, shielding members of two mating connectors may each have compliant members along their distal portions, such that, the shielding members engage at points of contact at multiple locations, some of which are adjacent the mating edge of each of the mating shielding members.

First claim

What is claimed is:

1. A subassembly for an electrical connector, the subassembly comprising:
a plurality of conductive elements each comprising a mating contact portion, a contact tail, and an intermediate portion extending between the mating contact portion and the contact tail; and
a plurality of shield members of electromagnetic shielding material, wherein:
the plurality of conductive elements are disposed in pairs,
at least the intermediate portions of the conductive elements of the pairs are disposed in a column,
the plurality of shield members are aligned in a direction parallel to the column,
the intermediate portions of each pair are at least in part surrounded by a shield member of the plurality of shield members, and
the shield members of adjacent pairs are electrically coupled within the subassembly.

2. The subassembly for an electrical connector of claim 1 , wherein:
adjacent pairs are separated by the electromagnetic shielding material.

3. The subassembly for an electrical connector of claim 1 , wherein:
the shield members of adjacent pairs comprise features that hold together and electrically couple the shield members.

4. The subassembly for an electrical connector of claim 1 , wherein:
the mating contact portions of each pair are at least in part surrounded by the shield member.

5. The subassembly for an electrical connector of claim 1 , comprising:
a plurality of contact tails electrically coupled to the shield members, and
the plurality of contact tails and the contact tails of the pairs form a mounting interface.

6. The subassembly for an electrical connector of claim 5 , wherein:
the plurality of contact tails extend from sides of the shield members and are offset from the sides of the shield members.

7. The subassembly for an electrical connector of claim 1 , further comprising:
lossy material electrically coupling the shield members.

8. A connector module comprising:
a plurality of conductive elements each comprising a mating contact portion, a contact tail, and an intermediate portion extending between the mating contact portion and the contact tail, at least the intermediate portion comprising broadsides joined by edges, the plurality of conductive elements being disposed in pairs that align broadside to broadside; and
electromagnetic shielding material at least in part surrounding each pair and separating adjacent pairs, wherein:
at least the intermediate portions of the conductive elements of the pairs are disposed in a column, and
each pair comprises transition regions between the intermediate portions and the mating contact portions of the conductive elements of the pair such that the mating contact portions of each pair are aligned in a pair direction that is at a non-right angle to the column.

9. The connector module of claim 8 , wherein:
the contact tails of the conductive elements in the pair are edge coupled.

10. The connector module of claim 9 , wherein:
the transition regions comprise jogs toward the broadsides of the intermediate portion of the other conductive element in the pair.

11. The connector module of claim 9 , wherein:
the transition regions comprise jogs away from the edges of the intermediate portions of the other conductive element in the pair.

12. The connector module of claim 8 , wherein:
the mating contact portions of the conductive elements in the pair are edge coupled.

13. The connector module of claim 12 , wherein:
the transition regions in a pair comprise jogs in first conductive elements of the pair toward the broadside of a second conductive element in the pair.

14. The connector module of claim 13 , wherein:
the transition regions in a pair comprise jogs in first conductive elements of the pair away from the edge of the intermediate portion of a second conductive element in the pair.

15. A connector module comprising:
a pair of conductive elements each comprising a mating contact portion, a contact tail, and an intermediate portion extending between the mating contact portion and the contact tail;
first and second shield members, each of the first and second shield members being U-shaped such that the first and second shield members together are disposed on at least three sides of the pair of conductive elements so as to at least partially enclose the pair of conductive elements, the first and second shield members separated by a gap; and
lossy material at least at a portion of the gap and electrically coupling the first and second shield members.

16. The connector module of claim 15 , wherein:
the portion of the gap is adjacent a transition region between the intermediate regions and contact tails of the pair.

17. The connector module of claim 15 , wherein:
the portion of the gap is adjacent a transition region between the intermediate regions and mating contact portions of the pair.

18. The connector module of claim 15 , wherein:
the first and second shield members are at least in part covered by the lossy material.

19. The connector module of claim 15 , comprising:
an insulative member supporting the pair of conductive elements and separating the pair of conductive elements from the first and second shield members.

20. The connector module of claim 15 , wherein:
the lossy material is at least partially between the portion of the gap.
