20110256763 | MITIGATION OF CROSSTALK RESONANCES IN INTERCONNECTS - In an electrical connector, a non-grounded, electrically conductive material (such as copper foil or other sheet of metal) may be located adjacent to at least one differential signal pair. An example includes a ring of material that circumscribes a leadframe assembly. Ring-shaped structures placed around, but not in contact with, the signal and ground contacts effectively mitigate cross-talk resonances in the interconnection structure. | 10-20-2011 |
20110318945 | ELECTRICAL CONNECTOR WITH GROUND PLATES - An electrical connector and leadframe assemblies for use therein are provided. Each leadframe assembly can be constructed with at least one electric contact having a ground plate. A first type of leadframe assembly includes an uppermost electrical contact defining a ground plate. A second type of leadframe assembly includes a lowermost electrical contact defining a ground plate. The ground plates can reduce the level of crosstalk exhibited by the electrical connector. | 12-29-2011 |
20110318962 | SIGNAL TRANSMISSION FOR HIGH SPEED INTERCONNECTIONS - A connector assembly includes a substrate and a connector. The substrate includes a ground layer and a trace layer. The substrate defines a substrate edge, and the ground layer defines a ground edge. The connector is mounted on the substrate such that a portion of the connector overhangs the substrate edge of the substrate. The connector includes a first signal contact that defines a mating portion, a mounting portion, a first transition portion connected to the mating portion, and a second transition portion connected to the first transition portion and the mounting portion. The first transition portion of the signal contact at least partially crosses the ground edge such that a gap is defined between the ground edge and the first transition portion and a substantial portion of the second transition portion extends over the gap when the electrical connector is mounted on the substrate. | 12-29-2011 |
20120058684 | LOW-CROSS-TALK ELECTRICAL CONNECTOR - An electrical connector includes a plurality of leadframe assembly, each having a leadframe housing and a plurality of contacts carried by the leadframe housing. At least a pair of adjacent leadframe assemblies includes respective first and second conductive member portions that are seated in the leadframe housing at a desired location with respect to the corresponding electrical contacts. | 03-08-2012 |
20130309906 | High Speed Edge Card Connector - A connector for connection between a circuit board and a further electronic component is disclosed. The connector includes an insulating housing having a board slot open towards a mating direction for accommodating the circuit board, and a plurality of terminals. The terminals have a rear portion, an intermediate portion and a tip portion, the intermediate portion including a contact portion for contacting a surface portion of the circuit board when accommodated in the board slot. The housing includes a window such that for a number of adjacent terminals housing material is absent between the intermediate portions. A shield member may be arranged in between the rear portions of the terminals. Improved circuit boards are also disclosed. | 11-21-2013 |
20140057493 | HIGH SPEED ELECTRICAL CONNECTOR - An electrical connector assembly includes a first electrical connector and a second electrical connector. Each electrical connector can include an electrical ground shield that at least partially surrounds respective differential signal pairs. | 02-27-2014 |
20140182891 | GEOMETRICS FOR IMPROVING PERFORMANCE OF CONNECTOR FOOTPRINTS - In accordance with the various embodiments disclosed herein, an improved electrical connector footprint, such as on printed circuit boards (PCB), is described. For example, antipads can have a variety of sizes and pairs of differential signal traces can define centerlines that are spaced apart from each other. | 07-03-2014 |
20150372427 | Connector Assembly - A connector is provided having a plurality of leads generally arranged in columns extending substantially parallel each other in a column direction and being adjacent each other in a row direction. At least one first column includes at least one first pair of signal leads substantially parallel each other in a first pair direction to form a first differential pair. In at least a portion of the connector the first pair direction extends at an acute angle to the column direction. Further, an assembly, and a circuit board are provided. | 12-24-2015 |
