  • Patent number: 12212100
    Abstract: A connector for use with high speed signals. The connector may include lead frame assemblies in a connector housing. A lead frame assembly may include signal conductive elements and ground conductive elements disposed in a repeating pattern, and one or more corrugated sheets attached to the ground conductive elements. The corrugated sheets may extend more than half of the length of the signal conductive elements. Valleys of the corrugated sheets may be welded to the ground conductive elements with line welds. The line welds may extend over a large percentage of the length of the conductive elements. Such a configuration enables accurately and repeatedly establishing signal to ground spacing and therefore promotes high signal integrity, even for miniaturized connectors. Such a connector may be used to meet signal integrity requirements in connectors designed for 112 GBps and beyond.

  • Publication number: 20240388023
    Abstract: A high frequency, high density electrical connector with structures that shorten ground loops in regions of the connector in which shorter ground loops results in less crosstalk and/or less insertion loss at high frequencies. The connector may multiple conductive elements including one or more signal conductors in line with ground conductors. The structures may be near the distal ends of the ground conductors and may divide larger ground loops into smaller ground loops in regions of the connector where the ground conductors are separated from a ground conductor in the complementary mating structure by a small distance. These structures may include a ground strip attached to extensions from a shield within the connector and/or a secondary beam extending from the ground conductors and positioned to contact the ground conductors in the complementary mating structure.

  • Patent number: 12150240
    Abstract: A printed circuit board includes a dielectric substrate; first and second conductive traces disposed on the dielectric substrate; and a compensation structure disposed in the first conductive trace. The compensation structure includes a compensation segment connected in line with the first conductive trace; and a dielectric layer on all or part of the compensation segment. The first and second conductive traces may form a differential signal pair. The compensation segment may limit one or more of signal skew, mode conversion from differential mode to common mode, and impedance variations caused by a bend in the differential signal pair.

  • Patent number: 10871119
    Abstract: A motor vehicle is disclosed having an internal combustion engine and an integrated starter-generator drivingly connected to a crankshaft of the internal combustion engine by a belt drive. Operation of the internal combustion engine and the integrated starter-generator is controlled by an electronic controller in response to a number of inputs. The electronic controller is arranged to use the internal combustion engine and the integrated starter-generator to actively reduce driveline shuffle in one of a number of shuffle reduction modes that are selected by the electronic controller based on at least the current rotational speed of the internal combustion engine.

  • Patent number: 10566719
    Abstract: A connector includes terminals with contacts. In an embodiment the contacts are positioned in a vertical connector similar to an edge card connector but with a differential pair aligned in a vertical direction. Thus the connector can provide edge-coupled differential pair in a high-density configuration.

  • Patent number: 10230192
    Abstract: A connector includes a housing with a plurality of electrically conductive terminals therein. Some terminals may include a terminal support projection that engages the housing to maintain the position of a contact section of the terminals relative to the housing. Others terminals may have a tool engaging shoulder configured to be engaged by a tool to force press-fit tails of all of the terminals into a circuit member. The housing may include a locking structure for certain the terminals that permits the terminals to be inserted into the housing with little or no force and then securely lock the terminals in the housing. One or more ground plates may be included for electrically connecting a plurality of the terminals. The ground plates may have resilient tabs that contact at least some of the terminals and the tabs may be thinner than a body portion of the ground plate.
