20090011620 | Differential signal connector with wafer-style construction - Stacked receptacles in a connector that each provide side-by-side differential signal contacts, are attached to a circuit board without additional width to accommodate multiple layers of differential signals by using connector wafer inserts that rotate the side-by-side positioned differential signal contacts to front-to-back contacts. | 01-08-2009 |
20110223805 | CONNECTOR SHIELD WITH INTEGRATED FASTENING ARRANGEMENT - A shield for a connector that can provide a card-receiving slot is disclosed. The shield includes sides that provide an enclosure. The shield includes a fastener that is held in place by a retaining notch in a bottom of the shield. The retaining notch is configured to support the fastener in place and restrain it from unintended translation or rotation. | 09-15-2011 |
20110223810 | CONNECTOR WITH IMPROVED MANUFACTURABILITY - An I/O connector has a housing that contains a plurality of individual terminal wafers containing terminal dedicated to either ground signals or differential signals. The terminals are arranged in widthwise order to define broadside coupled differential signal terminal pairs. The ground terminals are wider than the signal terminals to provide shielding to the differential signal pairs. The body portions of the ground terminals include pairs of opposed notches that provide for increased retention of the ground terminals in the wafer and provide increased flow for molding material during the formation of the wafers. | 09-15-2011 |
20110269346 | RESONANCE MODIFYING CONNECTOR - A connector assembly is provided that is suitable for controlling the resonance frequency of ground terminals used to shield high-speed differential pairs. Ground terminals may be commonized so as to provide ground terminals with a predetermined maximum electrical length. Reducing the electrical length of the ground terminal can move a resonance frequency of the ground terminals of the connector outside the range of frequencies at which signals will transmitted. | 11-03-2011 |
20110300757 | RESONANCE MODIFYING CONNECTOR - A connector assembly is provided that is suitable for modifying the resonant frequency of ground terminals used in conjunction with high data rate signal terminals. Ground terminals may be interconnected with a conductive bridge so as to provide ground terminals with a predetermined maximum effective electrical length. Reducing the effective electrical length of the ground terminal can move the resonance frequencies of the connector outside the operational range of frequencies at which signals will be transmitted. | 12-08-2011 |
20120003848 | HIGH DATA RATE CONNECTOR SYSTEM - A connector and circuit board assembly includes terminals in a connector that are mounted to vias in a circuit board. Signal and ground terminals are thus coupled to signal traces and ground planes in the circuit board. Additional pinning vias that are aligned with the ground vias may be provided in a circuit board to help improve electrical performance at the interface between the terminals in the connector and the signal traces in the circuit board. A signal collar may allow pairs of signal traces to be split and routed around two difference sides of a via before rejoining while maintaining close electrical proximity that provides for relatively consistent electrical coupling between the traces in the pair of signal traces. | 01-05-2012 |
20130072062 | CONNECTOR SHIELD WITH INTEGRATED FASTENING ARRANGEMENT - A shield for a connector that can provide a card-receiving slot is disclosed. The shield includes sides that provide an enclosure. The shield includes a fastener that is held in place by a retaining notch in a bottom of the shield. The retaining notch is configured to support the fastener in place and restrain it from unintended translation or rotation. | 03-21-2013 |
20130141181 | RESONANCE REDUCING CIRCUIT BOARD - A circuit card is provided that includes ground traces that extend from a resistor to a commoning bar, where a resultant electrical length between the resistor and the commoning bar and is configured to reduce energy carried on the ground terminals that could otherwise result in cross-talk. In an embodiment, the ground trace may be configured in a meandering manner. In another embodiment, the ground trace may be split and joined by an inductor. | 06-06-2013 |
20130157512 | ELECTRICAL CONNECTOR - An I/O connector has a housing that contains a plurality of individual terminal wafers containing terminal dedicated to either ground signals or differential signals. The terminals are arranged in widthwise order to define broadside coupled differential signal terminal pairs. The ground terminals are wider than the signal terminals to provide shielding to the differential signal pairs.

20130196550 | DIFFERENTIALLY COUPLED CONNECTOR - A connector is provided with a pair of terminals configured to provide a differential signal pair. A ground terminal is positioned on opposing sides of the differential pair. The body of the differential pair is configured so as to bring the differential pair closer together. In an embodiment, the % coupling on the differential pair is increase at least 10% more than a design where the four terminals are positioned at a constant pitch between the tail and the contact. | 08-01-2013 |
20130340251 | RESONANCE MODIFYING CONNECTOR - A connector assembly is provided that is suitable for modifying the resonant frequency of ground terminals used in conjunction with high data rate signal terminals. Ground terminals may be interconnected with a conductive bridge so as to provide ground terminals with a predetermined maximum effective electrical length. Reducing the effective electrical length of the ground terminal can move the resonance frequencies of the connector outside the operational range of frequencies at which signals will be transmitted. | 12-26-2013 |
20140065856 | GROUND TERMINATION WITH DAMPENED RESONANCE - A system of dampening resonance is provided. In an embodiment, ground traces may be coupled to a common or ground plane via dampening elements such as resistors a predetermined distance from a non-dampened coupling. Ground terminals in a connector have with a separated electrical length that allows for a potential to exist between the ground terminal and a common ground. When the ground terminals are coupled to the ground traces, the dampening element, which may be a resistor, helps convert energy traveling over ground terminal into heat, thus reducing or preventing resonance conditions in the connector. | 03-06-2014 |

Ground terminals may be interconnected with a conductive bridge so as to provide ground terminals with a predetermined maximum effective electrical length. Reducing the effective electrical length of the ground terminal can move the resonance frequencies of the connector outside the operational range of frequencies at which signals will be transmitted. | 10-16-2014 |
