Patent ID: 7976348

Claim:
A jack assembly, comprising: a jack housing defining a plug-receiving space; and an insert device positioned within the jack housing, the insert device including: an insert support member; a plurality of plug interface contacts mounted with respect to the insert support member, wherein at least one plug interface contact of the plurality thereof includes a first length extent extending along a first axial path and defining a first reaction surface that includes a first electrically conductive surface; and a reactance unit including a reactance circuit at least partially disposed within the plug-receiving space of the jack housing and operable to at least one of reduce and compensate for noise associated with signals conducted by the plug interface contacts of the plurality thereof, the reactance circuit further including a printed circuit board having an interconnection section including a plurality of interconnection elements and an end section including a plurality of capacitive elements in electrical communication with the interconnection elements of the plurality thereof, wherein at least one interconnection element of the plurality thereof defines a second reaction surface that includes a second electrically conductive surface; wherein in response to a mating plug being received in the plug receiving space of the jack housing, the insert device is operable to move the reactance circuit, including the interconnection section of the printed circuit board and the end section of the printed circuit board, relative to the at least one plug interface contact, and relative to the insert support member, by sliding the second reaction surface across the first reaction surface along an axial direction corresponding to the first axial path, and to press the second electrically conductive surface against the first electrically conductive surface with a force sufficient to preserve direct electrical communication between the reactance circuit and the at least one plug interface contact; the jack assembly further including: first and second pairs of conductors associated with the plurality of plug interface contacts; a first coupling of compensating crosstalk between the first pair of conductors and the second pair of conductors, wherein the first coupling of compensating crosstalk is provided by the reactance circuit; and a second coupling of compensating crosstalk between only a first conductor of the first pair of conductors and only a first conductor of the second pair of conductors.
