Communications jacks having conductive paths with the same current direction that inductively and capacitively couple

摘要

Communications jacks include a housing having a plug aperture that is configured to receive a mating RJ-45 plug along a longitudinal axis and eight jackwire contacts that are arranged as four differential pairs of jackwire contacts, each of the jackwire contacts including a plug contact region that extends into the plug aperture. A first of the jackwire contacts is configured to engage a longitudinally extending surface of a first blade of a mating RJ-45 plug when the mating RJ-45 plug is fully received within the plug aperture.

1. A communications jack, comprising:
a first conductive path electrically connecting a first input of the jack and a first output of the jack; a second conductive path electrically connecting a second input of the jack and a second output of the jack, wherein the first and second conductive paths comprise a first differential pair of conductive paths for transmitting a first information signal; a third conductive path electrically connecting a third input of the jack and a third output of the jack; a fourth conductive path electrically connecting a fourth input of the jack and a fourth output of the jack, wherein the third and fourth conductive paths comprise a second differential pair of conductive paths for transmitting a second information signal; and a return loss improvement circuit that comprises a first section of the first conductive path and a second section of the second conductive path that has the same instantaneous current direction as the first section of the first conductive path, wherein the first section and the second section are positioned to both capacitively and inductively couple with each other.
