  • Publication number: 20240006822
    Abstract: Electrical connectors for very high speed signals, including signals at or above 112 Gbps. Effectiveness of shielding along the signal paths through the mating electrical connectors may be enhanced through the use of one or more techniques, including enabling two-sided shielding, connections between shield members and between shield members and grounded structures of printed circuit boards to which the connectors are mounted, and selective positioning of lossy material. Such techniques may be simply and reliably implemented in high density connector using one or more techniques. An electrical connector may include core members held by a housing together with leadframe assemblies attached to the core members. The core members may include features that would be difficult to mold in a housing and may include both shields and lossy materials in locations that would be difficult to incorporate in a leadframe assembly.

  • Patent number: 11817657
    Abstract: A direct mate orthogonal connector for a high density of high speed signals. The connector may include right angle leadframe assemblies with signal conductive elements and ground shields held by a leadframe housing. High frequency performance may be achieved with members on the leadframe that transfer force between a connector housing, holding the leadframe assemblies, and a portion of the leadframe housing holding the signal conductive elements and the shields near their mounting ends. Core members may be inserted into the housing and mating ends of the conductive elements of ground shields may be adjacent the core members, enabling electrical and mechanical performance of the mating interface to be defined by the core members. The core members may incorporate insulative and lossy features that may be complex to form as part of the connector housing but may be readily formed as part of a separate core member.

  • Patent number: 11791585
    Abstract: Electrical connectors for very high speed signals, including signals at frequencies at or above 112 GHz, with high density. Such connectors may be formed with fine features molded into portions of the connector housing to support closely spaced signal conductors. The signal conducts may nonetheless be accurately positioned, which leads to uniform impedance and other electrical characteristics that enable high frequency operation through the use of skeletal members that restrain bowing and twisting of housing components that position, directly or indirectly, the signal conductors. The skeletal members may be simply incorporated into the housing components by stamping a metal skeleton from a metal sheet in conjunction with one or more carrier strips. The housing component may be overmolded around the skeleton and then severed from the carrier strips.
