Methods and apparatus for reducing crosstalk in electrical connectors
First Claim
1. A communication jack configured to receive a plug to form a communication connection, comprising:
- a plurality of jack contacts, which consist of metal cantilever beams, the plurality of jack contacts at least partially disposed within a plug receiving cavity in the jack, wherein each contact has at least a first surface and a second surface, wherein, upon the plug being received by the jack, a plurality of plug contacts interface with the first surface of the plurality of jack contacts; and
a first capacitive coupling connected between at least one pair of the plurality of jack contacts, wherein the first capacitive coupling is electrically and mechanically connected to the at least one pair of jack contacts such that the first capacitive coupling is suspended at least partially within the plug receiving cavity by the plurality of jack contacts.

Abstract
A communication jack having crosstalk compensation features for overall crosstalk interference reduction is disclosed. In one embodiment, the jack is configured to receive a plug to form a communication connection, and comprises jack contacts disposed in the jack, with each contact having at least a first surface and a second surface. Upon the plug being received by the jack, the plug contacts interface with the first surface of the jack contacts. The jack further includes a first capacitive coupling connected between two pairs of jack contacts to compensate for near end crosstalk, with the first capacitive coupling being connected to the pairs of jack contacts along the second surface adjacent to where the plug contacts interface with the jack contacts. A far end crosstalk compensation scheme is also set forth.
