Abstract:
The present disclosure relates to a telecommunications jack including a housing having a port for receiving a plug. The jack also includes a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing, and a plurality of wire termination contacts for terminating wires to the jack. The jack further includes a circuit board that electrically connects the contact springs to the wire termination contacts. The circuit board includes a multi-zone crosstalk compensation arrangement for reducing crosstalk at the jack.
Abstract:
Die Erfindung betrifft einen mehrpoliger Steckverbinder (10a, 10b) zur Kontaktierung mit einer Multilayerplatine (40), der Signal-Kontakte (11a, 11b; 12a, 12b) aufweist, denen ein erstes und wenigstens ein zweites Abschirm-Kontaktelement (17a, 17b, 17a', 17b'; 18a, 18b, 18a', 18b') zugeordnet und benachbart zum Signal-Kontakt (11 a, 11 b; 12a, 12b) angeordnet sind. Der Steckverbinder (10a, 10b) zeichnet sich dadurch aus, dass zumindest auf der obersten Schicht (41) der Multilayerplatine (40) Ausnehmungen (54, 54', 54") vorgesehen sind, welche zur Aufnahme und Durchführung von wenigstens zwei Abschirm-Kontaktelementen (17a', 17b'; 18a, 18b) bemessen sind, die benachbarten Signal-Kontakten (11a, 11b; 12a, 12b) zugeordnet sind.
Abstract:
The invention concerns a system (10) for transmitting differential signals, characterized in that it comprises at least a first and a second pairs of electrically conductive paths (12 -15), at least a path (13; 14) of the first pair being arranged between the paths (12, 14; 13, 15) of the second pair.
Abstract:
A printed circuit board ("PCB") includes a first pattern structure, a second pattern structure, a third pattern structure, and a fourth pattern structure. The first pattern structure includes a first ground pattern. The second pattern structure includes a first line pattern overlapping the first ground pattern and a second ground pattern electrically insulated from the first line pattern. The third pattern structure includes a third ground pattern overlapping the first line pattern and a second line pattern overlapping the second ground pattern. The fourth pattern structure includes a fourth ground pattern overlapping the second line pattern. Therefore, the PCB may decrease noise.
Abstract:
A wired circuit board (1) has an insulating layer (2) extending in a longitudinal direction, a conductive layer (3) having a plurality of signal wirings (4) covered with the insulating layer and arranged in mutually spaced-apart and parallel relation in a perpendicular direction to the longitudinal direction and a thickness direction of the insulating layer, and connecting terminals (5) provided on both longitudinal ends of each of the signal wirings and exposed from the insulating layer, and a ground layer (7) covered with the insulating layer and formed to surround each of the signal wirings in a perpendicular direction to the longitudinal direction. A slit (8) along the longitudinal direction is formed between each of the signal wirings in the insulating layer.
Abstract:
A printed circuit board includes a base (40) and a signal trace (47) formed on the base. The signal trace includes a plurality of straight line segments (C1,C2,C3,C4) parallel to the first fibers (41). The signal trace is formed on the base in such a manner that the line segments partially superpose the first fibers (41) and partly superpose gap between adjacent first fibers.
