  • Publication number: 20240097360
    Abstract: A modular high speed, high density electrical connector configurable for use in multiple configurations, including a direct attach orthogonal configuration. The connector is assembled with modules that include shielded pairs of signal conductors with mating ends that are rotated approximately 45 degrees with respect to intermediate portions of the signal conductors. The connector may have a mating interface with receptacles in one connector and pins in the mating connector. The pins may be small diameter and may be implemented with superelastic wires so as to resist damage despite having very small effective diameter. A compact mating interface resulting from small diameter mating contact portions may enable other portions of the connector, including the shielding surrounding the signal conductors to be smaller, which may raise the resonant frequency of the connector and extend its bandwidth.

  • Patent number: 11924202
    Abstract: Systems and methods are provided for establishing a secure communication link between a first client and a second client. One exemplary computer-implemented method for establishing a secure communication link between a first diem and a second client includes accessing, from a storage, identification information of a user of the first client. The method further includes receiving a Domain Name Service (DNS) request from the first client requesting a secure network address corresponding to a secure domain name associated with the second client. The method further includes authenticating the user based on the user identification information. The method also includes transmitting the secure computer network address in response to the DNS request based on a determination that the user has been authenticated. A secure communication link between the first diem and the second client is established based on the secure computer network address.

  • Publication number: 20240030660
    Abstract: A modular electrical connector with separately shielded signal conductor pairs. The connector may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. Modules of different sizes may be assembled into wafers, which are then assembled into a connector. Wafers may include lossy material. In some embodiments, shielding members of two mating connectors may each have compliant members along their distal portions, such that, the shielding members engage at points of contact at multiple locations, some of which are adjacent the mating edge of each of the mating shielding members.

  • Publication number: 20240014609
    Abstract: A modular electrical connector with broad-side coupled signal conductors in a right angle intermediate portion. Broadside coupling provides balanced pairs for very high frequency operation. The connector may be assembled with multiple subassemblies, each of which may have multiple pairs of signal conductors. The subassemblies may be formed from an insulative portion having grooves in opposite sides into which the intermediate portions of signal conductors. Covers, holding the signal conductors in the grooves, may establish the position of the signal conductors relative to reference conductors at the exterior of subassembly, so as to provide a controlled impedance. Lossy material may be positioned between the pairs in a subassembly and/or may contact the reference conductors of the subassemblies, and the lossy material of the subassemblies may in turn be connected with a conductive structure.

  • Publication number: 20230420874
    Abstract: An electrical interconnect for passing high speed signals through an electronic system with a high density of signals and high signal integrity. The interconnect includes an electrical connector and a transition portion of a printed circuit board to which the connector is mounted. Signal conductors are connected to pads on the surface of the PCB using edge-to-pad mounting. The pads align with intermediate portions of the signal conductors such that transitions within the connector that could degrade signal integrity are avoided. The signal conductors may be positioned as individually shielded broadside coupled pairs extending in rows within the connector. Surface traces on the PCB connect the pads to signal vias aligned for vertical routing out of the connector footprint. Ground planes underlying the surface traces facilitate a transition from the signal paths in the connector to those in the PCB with low mode conversion avoiding resonances in the connector shields.

  • Patent number: 11837814
    Abstract: A modular electrical connector with modular components suitable for assembly into a right angle connector may also be used in forming an orthogonal connector or connector in other desired configurations. The connector modules may be configured through the user of extender modules. Those connector modules may be held together as a right angle connector with a front housing portion, which, in some embodiments, may be shaped differently depending on whether the connector modules are used to form a right angle connector or an orthogonal connector. When designed to form an orthogonal connector, the extender modules may interlock into subarrays, which may be held to other connector components through the use of an extender shell. The mating contact portions on the extender modules may be such that a right angle connector, similarly made with connector modules, may directly mate with the orthogonal connector.

  • Patent number: 11824311
    Abstract: A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.

  • Patent number: 11764523
    Abstract: A modular electrical connector with separately shielded signal conductor pairs. In some embodiments, the connector is may be assembled from modules, each containing a pair of signal conductors with surrounding partially or fully conductive material. In some embodiments, the modules may have projecting portions, of conductive and/or dielectric material, that are shaped and positioned to reduce changes in impedance along the signal paths as a function of separation of conductive elements, when the connectors are separated by less than the functional mating range.

  • Publication number: 20230187861
    Abstract: A dense, high-speed interconnection may be formed with a mating header and receptacle connector. The header connector may have groups of mating contact portions extending from the connector housing. Structural projections may extend from the housing adjacent some or all of the groups of mating contact portions. The groups of mating contact portions may be signal and ground mating contact portions associated with a signal pair. The groups may be arranged in an array and the structural projections may be arranged in an array intercalated with the array of the groups of mating contact portions. A receptacle connector may include an array of apertures configured to receive the structural projections. The structural projections may be shaped and positioned to reduce damage to the mating contact portions of the header connector, enable reliable manufacture, and to provide a high-density mating interface.

  • Patent number: 11637401
    Abstract: A cable termination that provides low signal distortion even at high frequencies. Conductive elements of the cable are fused to edges of signal conductors in a cable connector or other component terminating the cable. For terminating a differential pair, the conductive elements of the cable may be terminated to opposing edges of a pair of signal conductors in the cable termination. The conductive elements may be shaped such that the spacing between signal paths passing through the conductive elements of the cable and into the signal conductors of the cable termination is uniform.
