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:

at least one conductive element defining a signal path, each conductive element of the at least one conductive element comprising a mating contact portion, a contact tail, and an intermediate portion extending between the mating contact portion and the contact tail;
one or more shield members disposed on four sides of the signal path so as to at least partially enclose the signal path; and
one or more lossy portions coupled to the one or more shield members at one or more locations along the signal path.

2. The connector module of claim 1 , wherein:
the one or more lossy portions comprise a lossy portion at least partially disposed inside the one or more shield members.

3. The connector module of claim 1 , wherein:
the signal path comprises a transition region between the intermediate portion and the mating contact portion of the at least one conductive element; and
the one or more locations along the signal path comprise the transition region.

4. The connector module of claim 1 , wherein:
the signal path comprises a transition region between the intermediate portion and the contact tail of the at least one conductive element; and
the one or more locations along the signal path comprise the transition region.

5. The connector module of claim 1 , wherein:
the one or more lossy portions comprise a lossy portion elongating along a length of the signal path.

6. The connector module of claim 5 , wherein:
the lossy portion extends along an entire length of the signal path.

7. The connector module of claim 1 , wherein:
the one or more lossy portions comprise a lossy portion at least partially disposed outside the one or more shield members.

8. The connector module of claim 1 , wherein:
the one or more shield members comprise a gap; and
the one or more lossy portions comprise a lossy portion at least partially disposed in the gap.

9. The connector module of claim 8 , wherein:
the one or more shield members comprise a pair of gaps facing each other; and
the lossy portion is at least partially disposed in the pair of gaps.

10. The connector module of claim 1 , wherein:
the one or more shield members are a plurality of shield members that cooperate to at least partially enclosing the signal path.

11. The connector module of claim 1 , wherein:
the one or more shield members comprises a first shield member on a first side of the connector module and a second shield member on a second side of the connector module;
the first shield member comprises segments disposed on three sides of the signal path;
the second shield member comprises segments disposed on three sides of the signal path;
the first shield member and the second shield member are disposed such that the segments of the first shield member and the segments of the second shield member are disposed on four sides of a space comprising the signal path; and
the one or more lossy portions are disposed within the space.
