Abstract

Electrical connector including a plurality of mating conductors. Each of the mating conductors extends between an engagement portion and an interior portion. The engagement portions of the mating conductors are configured to engage contacts of the mating connector. The engagement portions are located proximate to one another at a first nodal region. The interior portions are located proximate to one another at a second nodal region. The electrical connector also includes a first open-ended conductor electrically connected to the engagement portion of a first mating conductor of the plurality of mating conductors and extending from the first nodal region. The electrical connector also includes a second open-ended conductor electrically connected to the interior portion of a second mating conductor of the plurality of mating conductors and extending from the second nodal region. The first open-ended conductor is capacitively coupled to the second open-ended conductor.

6. The electrical connector of claim 1, wherein the plurality of mating conductors form a first compensation region and the first and second open-ended conductors form a second compensation region, the first and second compensation regions being parallel to each other between the first and second nodal regions.

7. The electrical connector of claim 1, further including a third open-ended conductor electrically connected to the first terminal of a third mating conductor of the plurality of mating conductors and a fourth open-ended conductor electrically connected to the second terminal of a fourth mating conductor of the plurality of mating conductors, wherein the third open-ended conductor is capacitively coupled to the fourth open-ended conductor.

8. The electrical connector of claim 1, wherein the connector body has an interior chamber configured to receive the plug connector when the plug connector is inserted therein in a mating direction, the plug connector having plug contacts that engage the plurality of mating conductors in the interior chamber.
