Patent number: 7481681Abstract: An electrical connector with improved crosstalk compensation is disclosed. By including at least one coupling with a different frequency dependency than other couplings in the connector, crosstalk compensation performance is improved over a greater frequency range. The different frequency dependency may, for example, be used to compensate for phase shifts caused by distances between compensation circuitry and the plug/jack interface. Embodiments for decreasing these distances are also disclosed.Type: GrantFiled: October 29, 2007Date of Patent: January 27, 2009Assignee: Panduit Corp.Inventors: Jack E.

Patent number: 7477069Abstract: The invention relates to a method and a device for transmission with reduced crosstalk in interconnections used for sending a plurality of signals, such as the interconnections made with flat multiconductor cables, or with the tracks of a printed circuit board, or inside an integrated circuit. An interconnection with four parallel transmission conductors plus a reference conductor has each of its ends connected to a termination circuit. The transmitting circuit receives at its input the signals of the four channels of the source and its output terminals are connected to the conductors of the interconnection. The receiving circuit(s) input terminals are connected to the conductors of the interconnection, and its four output channels are connected to the destination. The signals of the four channels of the source are sent to the four channels of the destination, without noticeable crosstalk.Type: GrantFiled: February 18, 2004Date of Patent: January 13, 2009Assignee: ZXtalk Assets, LLCInventors: Frederic Broyde, Evelyne Clavelier

Patent number: 7473138Abstract: An electrical connector includes a dielectric housing provided with a plurality of contact modules. Each of the contact modules is provided with a lead frame having mounting contacts electrically connected to mating contacts by signal conductors and ground conductors that extend along a predetermined path within the contact module. The lead frames in adjacent contact modules alternate between a first pattern and a second pattern. The first pattern and the second pattern each have pairs of signal conductors and individual ground conductors arranged in an alternating sequence. Each of the ground conductors has a width transverse to the predetermined path that is substantially equal to a combined width transverse to the predetermined path across the pair of signal conductors in the adjacent contact module such that the ground conductor shields the pair of signal conductors in the adjacent contact module.Type: GrantFiled: May 24, 2006Date of Patent: January 6, 2009Assignee: Tyco Electroics Nederland B.V.Inventors: Jacobus Nicolaas Tuin, Yves Braem, Johannes Marcelus Broeksteeg, Marcus Mybrand Wilhelmus Gosselink

Patent number: RE40575Abstract: A telecommunications electrical connector positions the contacts in a manner to reduce crosstalk problems. An insert assembly positions the spring contacts within a jack for electrical contact with the contacts of a plug. The insert assembly staggers the relative positions of adjacent spring contacts in the y-direction, and staggers the spring contact pivot points in the x-direction, yet maintains a common contact region for all the spring contacts for contacting the contacts of the plug. The distal ends of alternating spring contacts are positioned so as to increase the isolation between adjacent springs. The insert assembly includes selected air passages between spring contacts mounted to the insert assembly to increase isolation and selected dielectric to increase crosstalk cancellation.Type: GrantFiled: February 25, 2005Date of Patent: November 18, 2008Assignee: ADC Telecommunications, Inc.Inventors: John David Schmidt, Chansy Phommachanh, Roy Henneberger

Patent number: RE41052Abstract: A forward-reverse crosstalk compensation method is provided for compensating capacitance/inductance on a printed circuit board of a connector. The method includes a forward compensation process and a reverse compensation process. The forward compensation process compensates the unbalanced capacitance in the plug of the connector by using the parallel conductive lines or wires. The reverse compensation process can be used to compensate the unbalance capacitance/inductance caused by the forward compensations in the same pair combination of the connector. In both forward compensation and reverse compensation processes, electro-magnetic fields, such as capacitors, can be formed to balance the capacitance/inductance on the printed circuit board of the connector.Type: GrantFiled: April 2, 2007Date of Patent: December 22, 2009Assignee: ADC Telecommunications, Inc.Inventor: Chansy Phommachanh
