Abstract

A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.

First claim

What is claimed is:

1. A connector comprising:
a unitary housing comprising dividers and spaces between the dividers; and
a plurality of conductive elements held by the unitary housing, each conductive element comprising a mating contact portion, a contact tail opposite the mating contact portion, and an intermediate portion between the mating contact portion and the contact tail, wherein:
the mating contact portions of the plurality of conductive elements are of a same type,
the contact tails of the plurality of conductive elements comprise first contact tails configured for attachment to a printed circuit board and second contact tails configured for attachment to a cable, and
each space of the spaces between the dividers of the unitary housing is configured to receive two columns of the intermediate portions coupled to the first contact tails and two columns of the intermediate portions coupled to the second contact tails, whereby each space of the spaces is configured to have either two columns of the intermediate portions coupled to the first contact tails or two columns of the intermediate portions coupled to the second contact tails.

2. The connector of claim 1 , wherein:
the mating contact portions of the plurality of conductive elements are disposed in an array with a plurality of subarrays, with each subarray comprising a same pattern of mating contact portions, and
each subarray comprises at least one column of mating contact portions of the plurality of conductive elements.

3. The connector of claim 2 , wherein:
each subarray comprises two columns of mating contact portions of the plurality of conductive elements, and
for each pattern, the mating contact portions aligned in a direction perpendicular to the columns form a differential pair.

4. The connector of claim 3 , wherein:
the two columns in a subarray are separated by a first distance equal to a distance between two wires of the cable.

5. The connector of claim 1 , wherein:
the mating contact portions of the plurality of conductive elements are inside the unitary housing, and
the first contact tails of the plurality of conductive elements are outside the unitary housing.

6. The connector of claim 1 , wherein:
the mating contact portions of the plurality of conductive elements are configured as pins.

7. The connector of claim 1 , wherein:
the intermediate portions between respective mating contact portions and second contact tails are arranged in pairs, and
each pair is held by a module housing.

8. A connector comprising:
a plurality of cables, each cable comprising a dielectric portion and a pair of wires, each wire of the pair of wires comprising a first portion insulated by the dielectric portion and a second portion joining the first portion and disposed outside the dielectric portion; and
a plurality of pairs of conductive elements aligned in a column, each conductive element comprising a mating contact portion, a contact tail opposite the mating contact portion and comprising broadsides and edges joining the broadsides, and an intermediate portion between the mating contact portion and the contact tail, the contact tails of each pair of the plurality of pairs of conductive elements aligned in a plane, wherein, for each cable of the plurality of cables;
the second portions of the pair of wires are aligned in the plane in which the contact tails of a respective pair of the plurality of pairs of conductive elements are aligned; and
the second portions of the pair of wires are attached to respective edges of the contact tails of the respective pair of conductive elements without jogging out of the plane in which the contact tails of the respective pair of conductive elements are aligned.

9. The connector of claim 8 , wherein:
each cable comprises a shield surrounding the first portions of the pair of wires.

10. The connector of claim 8 , wherein:
the plurality of pairs of conductive elements are held by a unit housing in the column, and
the contact tails of the plurality of pairs of conductive elements are inside a wafer housing.

11. The connector of claim 10 , wherein:
the intermediate portions of each pair are held by a module housing, and
at least a portion of each module housing is inside the wafer housing.

12. The connector of claim 10 , wherein:
the wafer housing also holds the plurality of cables in a column.

13. The connector of claim 8 , wherein:
the plurality of pairs of conductive elements are a first plurality of pairs of conductive elements,
the connector comprises a second plurality of pairs of conductive elements, each conductive element comprising a mating contact portion, a contact tail opposite the mating contact portion, and an intermediate portion between the mating contact portion and the contact tail, and
the contact tails of the second plurality of pairs of conductive elements are configured for attachment to a printed circuit board.

14. The connector of claim 13 , wherein:
the first and second plurality of pairs of conductive elements are held by first and second wafer housings in two parallel columns.

15. A connector comprising:
a mating interface comprising a plurality of mating contact portions, the plurality of mating contact portions being of a same type;
a first mounting interface comprising a plurality of first contact tails extending opposite and coupled to respective mating contact portions of a first portion of the plurality of mating contact portions, the plurality of first contact tails configured for attachment to a printed circuit board;
a second mounting interface comprising a plurality of second contact tails extending opposite and coupled to respective mating contact portions of a second portion of the plurality of mating contact portions, the plurality of second contact tails configured for attachment to a cable; and
a housing encircling the plurality of mating contact portions, the housing comprising dividers and spaces between the dividers,
wherein each space of the spaces between the dividers of the housing is configured to receive two columns of the mating contact portions of the first portion and two columns of the mating contact portions of the second portion, whereby each space of the spaces is configured with either two columns of the mating contact portions of the first portion or two columns of the mating contact portions of the second portion.

16. The connector of claim 15 , wherein:
the second mounting interface is perpendicular to the first mounting interface.

17. The connector of claim 15 , wherein:
the second mounting interface is parallel to the mating interface.

18. An electronic system, comprising:
