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.

A compliant contact array for interconnecting conductive components in an electrical interconnect. The compliant contact array may include a plurality of features for contacting the conductive components. These and other features of the contact array may be relatively fine, such that contact arrays may make connections in a high density interconnection system or position metal to improve signal integrity, enabling high speed connectors. Further, features of the contact array may be shaped or positioned to provide desired mechanical properties such as a desired range of compliance and/or contact pressure. Features may control wall thickness of contact regions or enable telescoping or control the direction of flow of an elastomeric base region. The contact regions may be convex on one side and concave on another side. The compliant contact array may have a conductive layer applied thereon for electrically connecting the electrical connector to the conductive components.

High speed, high density I/O connector assemblies. An I/O connector assembly includes a cage and a heat dissipation member. The cage includes a top wall having an opening and a channel accessible from the front. The heat dissipation member includes a base disposed at the top of the cage, multiple sections separated by gaps, and a contact portion protruding from the base in a first direction into the channel through the opening of the top wall. Each section includes fins protruding from the base in a direction opposite to the first direction. The heat dissipation member comprises a layer of micro thermal interface material at a contact interface. Techniques described herein, including the structure and material composition of components, can provide sufficient heat dissipation to enable high speed, high density I/O connector assemblies that nonetheless can be economically manufactured and meet the dimensional requirements of an OSFP-XD standard.

A twin-axial cable is provided. The twin-axial cable includes a first conductor having a length along a longitudinal direction and a second conductor parallel to the first conductor along the longitudinal direction. The twin-axial cable further includes a primary insulation including a first core and a second core, the first core surrounding the first conductor and the second core surrounding the second conductor, each of the first core and the second core being shaped as a horizontal cylindrical segment comprising a surface extending along the longitudinal direction. The surfaces of the first core and the second core are disposed in contact with one another, and a ratio between a first distance, c, between the first conductor and the second conductor to a distance, a, between the first conductor and an edge of the primary insulation in the plane and opposite the second conductor is 1.8 or less.

A connector assembly includes an electrical connector including a plurality of electrical contacts and a backplane connector electrically connectable to the electrical connector. The backplane connector is positioned along an axis with the electrical connector and is movable within a plane arranged at an angle relative to the axis. An interposer member is mechanically connected to and electrically connectable to the plurality of electrical contacts and is positioned along the axis. The interposer member is positioned between the electrical connector and the backplane connector.
