Abstract: An electrical connector includes a dielectric housing, a plurality of electrical signal contacts carried by the dielectric housing, and a ground plate carried by the dielectric housing. The electrical signal contacts are arranged along a first plane, wherein the signal contacts define signal pairs such that a respective gap is disposed between adjacent signal pairs. The signal contacts further define respective mating and mounting ends. The ground plate includes a ground plate body oriented in a second plane that is substantially parallel to the first plane and offset from the first plane. The ground plate body defines first and second opposed surfaces. The ground plate includes at least one rib that defines first and second opposed surfaces, wherein the first surface of the rib projects from the first surface of the ground plate body in a direction toward the gap, and the second surface is recessed into the second surface of the ground plate body.

Abstract: An electrical connector is provided having an electrically insulative connector housing that supports a plurality of signal contacts, as well as a plurality of ground contact networks. The ground contact networks include a conductive ground coupling bar supporting a plurality of ground contacts along a pair of columns that are spaced apart along a row direction.

Abstract: An electrical connector assembly includes a first electrical connector and a second electrical connector that can be mated so as to establish an electrical connection across the electrical connectors at a mating region. One of the electrical connectors includes a perforated common ground shield at the mating region that reduces crosstalk while substantially matching impedance at the mating region to a desired impedance of the electrical connector assembly.

Abstract: An electrical connector includes a dielectric housing, a plurality of electrical signal contacts supported by the dielectric housing, and an electrically conductive ground plate supported by the dielectric housing. The dielectric hosing defines at least one protrusion, and the ground plate defines at least one aperture that receives the protrusion. The apertures can define a first dimension along a select direction and a second dimension along the select direction, wherein the first dimension is greater than the second dimension so as to define a lead-in for the protrusion. The protrusion can be press-fit to the electrically conductive ground plate at the second dimension of the aperture so as to secure the ground plate to the dielectric housing.

Abstract: An electrical connector includes a conductive connector housing that supports a plurality of contact modules that includes electrical ground contacts and electrical signal contacts electrically isolated from each other in the respective contact modules. The electrical ground contacts are in electrical communication with the connector housing so as to electrically common the ground contacts together.
