Abstract:
A connector is provided for compensating crosstalk with respect to an adjacently placed connector. Each of the connectors includes a printed circuit board (PCB), a plurality of pairs of contacts on the PCB, a plurality of pads disposed at edge portions of the PCB for compensating crosstalk, and a plurality of connecting parts for connecting electrically the pads to the pairs of contacts.
Abstract:
A communications jack includes: a jack frame having a plug aperture; a plurality of contact wires, the contact wires having free ends that extend into the plug aperture, the free ends of the contact wires being arranged serially in side-by-side relationship; a plurality of insulation displacement connectors; a dielectric mounting substrate, the mounting substrate including a plurality of mounting locations for contact wires and a plurality of mounting locations for insulation displacement connectors; and a plurality of conductors mounted on the substrate, each of the conductors extending, defining a path, and establishing electrical connection between a contact wire mounting location and an insulation displacement connector mounting location. At least one of the conductors includes two self-coupling sections that are immediately adjacent to each other and that have identical instantaneous current direction such that the sections self-couple and cause a localized increase in inductance.

A communications jack includes: a jack frame having a plug aperture; a plurality of contact wires, the contact wires having free ends that extend into the plug aperture, the free ends of the contact wires being arranged serially in side-by-side relationship; a plurality of electrical terminals, the terminals being arranged in pairs, each pair defining a communication channel; a dielectric mounting substrate, the mounting substrate including a plurality of mounting locations for contact wires and a plurality of mounting locations for the electrical terminals; and a plurality of conductors mounted on the substrate, each of the conductors extending, defining a path, and establishing electrical connection between a contact wire mounting location and an electrical terminal mounting location. First and second of the conductors that are connected to one of the pairs of terminals each include a coupling section, the coupling sections being immediately adjacent to each other and having identical instantaneous current direction such that the sections couple and cause a localized increase in inductance.
Abstract:
A communications connector includes: a dielectric mounting substrate; at least four pairs of conductors mounted on the mounting substrate, each of the conductors including a free end segment, each of the free end segments being positioned in side-by-side and generally parallel relationship; and at least four pairs of terminals mounted on the mounting substrate, wherein each of the pairs of terminals is electrically connected to a respective pair of conductors. A first pair of conductor free end segments is immediately adjacent each other, a second pair of conductor free end segments is immediately adjacent each other and positioned one side of the first pair, a fourth pair of conductor free end segments is immediately adjacent each other and positioned on an opposite side of the first pair, and a third pair of conductor free end segments sandwiches the first pair, with one of the conductor free end segments of the third pair being disposed between the first and second pairs, and the other of the conductor free end segments being disposed between the first and fourth pairs. Each of the first, second and fourth pairs of conductors includes a crossover between the conductors of the pairs, and the third pair of conductors includes three crossovers between its conductors.
