Abstract

Abstract This invention is directed to an improved system for reducing crosstalk in an electrical connector, where a typical connector is a multi-contact electrical connector comprising a pair of intermatable connector members, where each connector member is adapted to be terminated to plural conductors. A typical connector comprises a housing formed of an insulative material having a conductor receiving side, a mating side, and a plurality of contact receiving cavities extending from the conductor receiving side to said mating side. The cavities are arranged in rows on a spaced-apart parallel axes, where adjacent rows are separated by an insulative housing wall. An array of electrical contact terminals are provided in the cavities. A preferred system hereof is the provision of an electronic device in the form of a thin dielectric film, having plural discrete electrically conductive traces along a first surface thereof, where the first surface is arranged adjacent the insulating wall underlying the contact terminals. By this arrangement capacitive coupling of energy between selected pairs of contact terminals is achieved.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 210 words
In a multi-contact electrical connector comprising a pair of intermatable connector members, where each said connector member is adapted to be terminated to plural conductors, and each said commuter member comprises a housing formed of an insulative material and having a conductor receiving side and a mating side, a plurality of contact receiving cavities extending from said conductor receiving side to said mating side, said cavities being arranged in rows on spaced-apart parallel axes, where adjacent rows are separated by an insulative housing wall, and an array of electrical contact terminals mounted in said cavities, each of said contact terminals having contact means at its forward end proximate to said mating side and conductor terminating means proximate to said conductor receiving side, the improvement comprising in combination therewith the provision of incorporating an electronic device between the insulative housing wall and said contact terminals mounted within said cavities, said electronic device comprising a thin dielectric film having plural discrete electrically conductive traces along a first surface thereof, where said first surface is arranged adjacent said insulative housing wall, whereby selected pairs of said contact terminals are non-ohmically coupled together via said conductive traces to improve connector performance through capacitive coupling of energy between said selected pairs of said contact terminals.
Claim 2
Dependent Claim 210 words
In a multi-contact electrical connector comprising a pair of intermatable connector members, where each said connector member is adapted to be terminated to plural conductors, and each said commuter member comprises a housing formed of an insulative material and having a conductor receiving side and a mating side, a plurality of contact receiving cavities extending from said conductor receiving side to said mating side, said cavities being arranged in rows on spaced-apart parallel axes, where adjacent rows are separated by an insulative housing wall, and an array of electrical contact terminals mounted in said cavities, each of said contact terminals having contact means at its forward end proximate to said mating side and conductor terminating means proximate to said conductor receiving side, the improvement comprising in combination therewith the provision of incorporating an electronic device between the insulative housing wall and said contact terminals mounted within said cavities, said electronic device comprising a thin dielectric film having plural discrete electrically conductive traces along a first surface thereof, where said first surface is arranged adjacent said insulative housing wall, whereby selected pairs of said contact terminals are non-ohmically coupled together via said conductive traces to improve connector performance through capacitive coupling of energy between said selected pairs of said contact terminals.
Claim 3
Dependent Claim 19 words
