摘要： A printed circuit board (100) exit arrangement is disclosed for use in high speed connector mounting applications. A ground plane (104) has one or more open areas (105) formed in it that surround pairs of signal vias (102) formed in the board (100) that are used to convey differential signals. The ground plane (104) has a thin interconnecting strip (107), or web, that passes between the two vias (102) of each pair and which divides the open areas (105) into sub-areas (105a, 105b), each sib-area containing a single via.

摘要： Termination assemblies for terminating high-frequency data signal transmission lines include housings with one or more cavities that receive ends of the transmission line therein. The transmission line typically includes a dielectric body and a plurality of conductive elements disposed thereon, with the plurality of conductive elements being arranged in pairs for differential signal transmission. The termination assemblies, in one embodiment include hollow end caps that are formed from a dielectric and which have one or more conductive contacts or plated surfaces disposed on or within the cavity so that they will frictionally mate with the conductive traces on the transmission line. In another embodiment, a connector housing is provided with a center slot and a plurality of dual loop contacts to provide redundant circuit paths and low inductance to the termination assembly. A coupling element may be utilized in the slot to achieve a desired level of coupling between the termination contacts.

摘要： A connector that is particularly suitable for use in high speed data transmission is provided in the form of a plug connector (104) that may be terminated to the end of a high speed cable (105). The connector has a plurality of terminals (140, 141, 150, 253, 254) for terminating to respective signal wires, ground wires and power wires of the cable, and also has an additional terminal (252) that serves to detect and identify status information about the cable to circuits on a circuit board to which the cable is connected through the plug connector and a mating receptacle connector (110). This detection terminal is shorted to another terminal of the connector, preferably a power ground, or return, terminal (254). The shorting is done with an electronic component that modifies the voltage passing from the shorted terminal through the detection terminal. The modified voltage may be easily read on the circuit board to determine the status of the cable (such as the speed of the cable), or an electronic device attached thereto.

摘要： A determination structure for mating a cable connector to a circuit board includes a plurality of associated sets of terminals, each terminal set including a pair of differential signal terminals and a ground reference terminal. Each associated set of terminals is arranged in triangular pattern through the connector in order to reduce the impedance through the connector, and adjacent associated terminal sets are inverted so that the ground reference terminals of alternating associated terminal sets are located along one row of the connector along with signal terminals of intervening terminal sets, while the ground refence terminals of intervening terminal sets are located along a second row of the connector, along with the signal terminals of alternating associated terminal sets. This inverted arrangements increases the density of the connector.

摘要： A reduced-cross-sectional area, triad transmission line is formed by plating or metallizing surface area of a substrate, along the edge of a slot cut through the substrate. The cross-sectional area of such conductors that faces each other is reduced, reducing the signal coupling between them when they are carrying high-frequency signals. An intervening ground plane between them is provided by metallization on the slot bottom that is held at ground potential.

摘要： A circuit board (200, 300, 400) design is disclosed that is useful in high speed differential signal applications uses either a via arrangement or a circuit trace exit structure. In the via arrangement, sets of differential signal pair vias (301, 303, 401, 402) and an associated ground (302) are arranged adjacent to each other in a repeating pattern. The differential signal vias (301, 303, 591) of each pair are spaced closer to their associated ground via (302a, 593a) than the spacing between the adjacent differential signal pair associated ground (302b, 593b) so that differential signal vias exhibit a preference for electrically coupling to their associated ground vias. The circuit trace exit structure involves the exit portions of the circuit traces (420, 550) of the differential signal vias (401, 402, 591) to follow a path where the traces then meet with and join to the transmission line portions (552) of the conductive traces.

摘要： A transmission line for high-frequency differential signals and having a transforming impedance is formed into a substrate. The transmission line is comprised of a first slot, the opposing surfaces of which carry a conductive surface capable of carrying electrical signals. By virtue of their dimensions, spacing and dielectric filler, the conductive surfaces constitute a transmission line. A second slot, also with opposing surfaces, each of which also carry a conductive surface but which are spaced differently than the opposing surfaces of the first slot, provide a second transmission line but with a different impedance. The impedances between the two transmission lines are transformed by an impedance transition section of transmission line that is slot section the dimensions of which are tapered to meet the different slot dimensions of the two different transmission line segments.

摘要： A terminal contact arrangement for a connector promotes reduction in deviation of the impedance of the connector when mated to an opposing connector and energized. The connector has an insulative housing with a plurality of terminal-receiving passages disposed in it. Conductive terminals are supported in some, but not all of the passages. The terminal contain distinct terminal sets that include a pair of differential signal terminals and at least two associated ground reference terminals. The two associated ground reference terminals are interconnected together so that electrically, they act as a single ground terminal having a width equal to the sum of the widths of the two connected ground reference terminals. The ground reference terminals of the sets are disposed in a single row of terminals, while the differential signal terminals of the same terminal set are disposed in another row of terminals spaced apart from the row of ground reference terminals. The differential signal terminals are separated from each other within their terminal row by an empty passage so that the two differential signal terminals of each terminal set are spaced farther apart from each other than they are spaced apart from their associated ground reference terminals.

摘要： A termination structure for a cable connector (104) having a pair of differential wire pairs and an associated ground wire utilizes a series of nests (183, 193), or solder cups, that have their dimensions tailored to maintain a desired level of electrical performance. These nests are also arranged in a configuration to maintain the aforementioned electrical performance, and also position the ground (650) and signal (653) conductors of the cable in the termination area in the same position and orientation as they take in the cable.
