  • Publication number: 20190326703
    Abstract: A cage for a stacked I/O connector that provides heat dissipation sufficient to support operation of QSFP-DD transceivers with a conventionally-sized cooling fan. The cage includes a second channel, between a first and a third channel that are sized and positioned adjacent ports of a connector so as to receive two transceivers. A face of the second channel may have a pattern of openings that enables a high airflow yet blocks electromagnetic radiation that would otherwise contribute to EMI. An element, adjacent the channel that similarly has a pattern of holes enabling high airflow, may further block EMI.

  • Publication number: 20190319402
    Abstract: An interconnection system including a pluggable transceiver and a connector disposed in a cavity of a conductive cage. The pluggable transceiver may include a latching mechanism for locking to the conductive cage. The latching mechanism may include a pair of latches positioned on opposite sides of the pluggable transceiver. The latches may be spatially offset from each other along a longitudinal and/or vertical direction. Corresponding latching tabs in the conductive cage may be disposed in the same relationship, even in a ganged configuration when latching tabs for adjacent cavities are formed in a common wall between cavities. Cammed surfaces of a release mechanism, centered between latching edges of the transceiver latches may impart a latch releasing force at a central portion of the latching tab forcing the lathing tab back into the common wall, reducing rotational moment applied in prior designs, such as QSFP ganged cages.

  • Publication number: 20190260147
    Abstract: Embodiments related to electrical connectors including superelastic components are described. The high elastic limit of superelastic materials compared to conventional connector materials may allow for designs which provide reliable connections and high frequency operation. Superelastic components also may enable connector designs with higher densities of connections. In some embodiments, a connector includes one or more superelastic elongated members forming the mating contacts of the connector. The superelastic elongated members deform within one or more conductive receptacles to generate a suitable contact force. The conductive receptacles may include a plurality of protrusions arranged to deflect the superelastic elongated members during mating.

  • Publication number: 20190252832
    Abstract: A cable assembly comprising a termination with at least one conductive, compressible member and a conductive ground shield. The conductive, compressible member may be held within a connector module forming the termination such that the conductive compressive member is pressed against, and therefore makes electrical contact with, both an outer conductive layer of the cable and ground structures within the connector module. In some embodiments, these connections may be formed using a conductive, compressible member with an opening configured to receive the end of the cable therethrough. The conductive ground shield may be configured to compress the conductive, compressible member, and to cause the conductive, compressible member to electrically contact the cable's conductive layer. The conductive, compressible member may be formed from a compressible material and may comprise a plurality of conductive particulates configured to provide electrically conductive paths.

  • Patent number: 10381767
    Abstract: A cable connector with improved performance and ease of use. The connector has staggered ports to reduce crosstalk and to prevent incorrect insertion of a plug into a receptacle. The plug may be constructed with subassemblies, each of which has a lossy central portion. Conductive members embedded within an insulative housing of the subassemblies may be used to electrically connect ground conductors within the subassemblies. Further, the connector may have a quick connect locking screw that can be engaged by pressing on the screw, but requires rotation of the screw to remove. Additionally, a ferrule may be used in making a mechanical connection between a cable bundle and a plug and making an electrical connection between a braid of the cable bundle and a conductive shell of the plug. The ferrule may be in multiple pieces for easy attachment while precluding deformation of the cable, which disrupts electrical performance.

  • Publication number: 20190221973
    Abstract: An electrical connector for high speed signals. The connector has multiple conductive elements that may serve as signal or ground conductors. A member formed with lossy material and conductive compliant members may be inserted in the connector. The conductive compliant members may be aligned with conductive elements of the connector configured as ground conductors. For a connector configured to carry differential signals, the ground conductors may separate pairs of signal conductors. The member may further include a conductive web, embedded within the lossy material, that interconnects the conductive compliant members. For a receptacle connector, the conductive elements may have mating contact portions aligned along opposing surfaces of a cavity. The conductive elements may have contact tails for attachment to a printed circuit board and intermediate portions connecting the mating contact portions and the contact tails. The conductive compliant members may press against the intermediate portions.

  • Publication number: 20190173236
    Abstract: An interconnection system with a compliant shield between a connector and a substrate such as a PCB. The compliant shield may provide current flow paths between shields internal to the connector and ground structures of the PCB. The connector, compliant shield and PCB may be configured to provide current flow in locations relative to signal conductors that provide desirable signal integrity for signals carried by the signal conductors. In some embodiments, the current flow paths may be adjacent the signal conductors, offset in a transverse direction from an axis of a pair of conductors. Such paths may be created by tabs extending from connector shields. A compliant conductive member of the compliant shield may contact the tabs and a conductive pad on a surface of the PCB. Shadow vias, running from the surface pad to internal ground structures may be positioned adjacent the tip of the tabs.

  • Patent number: 10305224
    Abstract: An electrical interconnection system comprising one or more insulative projecting members. The electrical interconnection system may comprise a first connector and a second connector. Each connector may comprise one or more projecting members extending along the mating direction. When the connectors are mated, the projecting member(s) may be configured to affect the impedance of the signal conductors of the connectors. In a partially mated position, the projecting member(s) may be configured to fill at least a portion of the region separating the connectors, thereby replacing air that might otherwise exist in that separation with a dielectric member. Because this dielectric constant is closer to what would be experienced in the fully mated position, the magnitude of the change in impedance as a result of separation may be less than had the entire space been filled with air.
