Inductive and capacitive coupling balancing electrical connector
First Claim
1. A jack connector for terminating a network cable that includes at least two pairs of conductors, the first pair comprising first and second conductors and the second pair comprising third and fourth conductors, the jack connector comprising:
- a printed circuit board (PCB) with a plurality of electrical traces,wherein first, second, third, and fourth electrical traces are provided respectively for each of the first, second, third, and fourth conductors,wherein each electrical trace passes through at least two inductive coupling zones separated by a neutral zone that is substantially void of any intentionally introduced inductive coupling between adjacent electrical traces,wherein the at least two inductive coupling zones comprise a compensation zone and a crosstalk zone,wherein the compensation zone comprises inductive couplings between the second and third electrical traces and between the first and fourth electrical traces, andwherein the crosstalk zone comprises inductive couplings between the second and fourth electrical traces and between the first and third electrical traces.

Abstract
A network cable jack includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. Using a PCB allows compact trace paths to be formed without significantly increasing manufacturing costs. By including on each trace path two distinct inductance zones separated by a neutral zone, significant gains in degrees of freedom are achieved for designing PCB trace patterns in which a pair of inductive coupling zones jointly offset the inductive coupling caused by a specification plug and the jack contacts, both in magnitude and phase angle. Further, using distinct inductance zones offers more freedom regarding the placement of capacitive plates for use in capacitance balancing as well as the placement of terminals and insulation displacement contacts. Although the magnitude of a capacitive coupling is determined by the length of the capacitor plates parallel to current carrying traces, the approach allows capacitive and inductive coupling to be balanced independently.
