Patent number: 6786775Abstract: A terminal module is provided, such as for use in a modular jack assembly. The module includes a dielectric body having a pair of body halves with opposing faces. A plurality of terminals have mounting portions embedded in the opposing faces of the body halves. The terminals are securely captured in the dielectric body when the mounting portions are sandwiched between the body halves.Type: GrantFiled: June 10, 2003Date of Patent: September 7, 2004Assignee: Molex IncorporatedInventors: Mark Hanrahan, Chansy Phommachanh, James Roberts, John C. Kiezulas

Patent number: 6629862Abstract: 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: December 17, 2001Date of Patent: October 7, 2003Assignee: ADC Telecommunications, Inc.Inventors: John David Schmidt, Chansy Phommachanh

Patent number: 6520806Abstract: The present disclosure relates to an electrical connector including a plurality of contact springs having contact regions aligned generally along a single line of contact. The contact springs include rearwardly and forwardly facing contact springs that are positioned next to one another. The rearwardly facing contact spring includes a distal portion positioned behind the contact line and a proximal portion positioned in front of the contact line. The forwardly facing contact spring includes a distal portion positioned in front of the line of contact and a proximal portion positioned behind the line of contact.Type: GrantFiled: August 20, 1999Date of Patent: February 18, 2003Assignee: ADC Telecommunications, Inc.Inventor: Chansy Phommachanh

Patent number: 6504726Abstract: A telecommunications module with a circuit board including pairs of connectors mounting on both sides of the circuit board held within a housing by structure that holds the circuit board offset from the front and rear of the module and connectors accessible openings in the rear wall of the module. A telecommunications patch panel including one or more modules mounted to the rear of a faceplate, each module with a circuit board including pairs of electrically linked connectors mounting on both sides of the circuit board held within the module by structure that holds the circuit board offset from the front and rear of the module with connectors accessible through a rear wall of the module and through the faceplate. A method of assembling a telecommunications module and a method of assembling a telecommunications patch panel including one or more modules attached to the rear of a faceplate.Type: GrantFiled: November 16, 2001Date of Patent: January 7, 2003Assignee: ADC Telecommunications, Inc.Inventors: Cory Lee Grabinger, Chansy Phommachanh

Patent number: 6482039Abstract: A modular jack assembly for connecting and switching computer network cables. The jack assembly includes at least one jack module with two sets of connectors for linking wires from cables to the module and at least one jack. The modules within jack assembly slide between a first position and a second position. In the first position, the two sets of connectors linked to cables are electrically connected to each other, allowing normal through signals transmission. In the second position, the electrical connection between the connector sets is broken and the plug contacts within each jack are linked to one of the sets of connectors, allowing pass-through connections, such as a cross-connection, to be made.Type: GrantFiled: January 2, 2002Date of Patent: November 19, 2002Assignee: ADC Telecommunications, Inc.Inventors: Chansy Phommachanh, Roy Lee Henneberger, Gregory D. Spanier, David DeYoung

Patent number: 6428362Abstract: 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: June 6, 2000Date of Patent: August 6, 2002Assignee: ADC Telecommunications, Inc.Inventor: Chansy Phommachanh
