Modular jack contact assembly having controlled capacitive coupling positioned within a jack housing
Patent number: 10637196Abstract: A modular jack connector compensates for plug characteristics via a controlled primary compensation in the immediate vicinity of the connector interface. A jack contact assembly is positioned within a jack housing and includes first and second sets of elongate contacts each having a plug contact portion and a signal output portion. Each elongate contact is configured such that their respective plug contact portions are coplanar and a signal path is defined between their plug contact portions and their signal output portions. A flexible circuit board is coupled proximate to the plug contact portions, and configured to provide capacitance compensation between respective contacts engaged thereby, wherein the capacitance compensation is offset from a signal path defined between the plug contact portions and the corresponding signal output portions.Type: GrantFiled: January 28, 2019Date of Patent: April 28, 2020Assignee: Bel Fuse (Macao Commercial Offshore) LimitedInventors: Andrew David Baum, Yakov Belopolsky, David Henry Gutter, Derek Imschwseiler, Richard D.

Patent number: 10530106Abstract: A modular RJ45-type plug apparatus is provided for forming a connector interface with a connector jack in a high speed data transmission network. A housing comprises an insulative front portion and a conductive shield portion attachable to define an interior, within which is positioned a contact subassembly including a first PCB having cable mounting pads on one end and through holes for elongate plug contacts on the other end. The contacts are connected on one end to the first PCB and on a second end to a second PCB, with bridge portions therebetween collectively defining a jack contact interface. The second PCB comprises desired electrical characteristics which provide the apparatus with certain capacitance compensation properties, wherein the capacitance compensation is offset from a signal path defined between the jack-plug connector interface and the cable pairs.Type: GrantFiled: January 30, 2019Date of Patent: January 7, 2020Assignee: Bel Fuse (Macao Commercial Offshore) LimitedInventors: Andrew David Baum, Richard D.

Patent number: 10439329Abstract: A modular connector plug includes controlled capacitances to compensate for near end cross talk at the connector interface created by interaction of signals having signal frequencies in a data transmission bandwidth. A printed circuit board (PCB) is configured to receive cable pairs, and a connector assembly includes first and fourth plug contacts corresponding to the first cable pair and second and third plug contacts corresponding to the second cable pair. First ends of each contact are connected to the PCB, and second ends extend in parallel with each other and transversely to the PCB length, collectively defining a contact interface proximate the contact end. Each contact has a maximum width at the contact interface, with at least one plug contact having a maximum width greater than the maximum width of another plug contact. Each contact accordingly defines an electrode of a compensating capacitance formed between adjacent pairs of plug contacts.Type: GrantFiled: October 18, 2017Date of Patent: October 8, 2019Assignee: Bel Fuse (Macao Commercial Offshore) LimitedInventors: Richard D.
