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.

A data connector adapter includes a plug body having first and second plug connection ends, an electrically conductive plug shield and a contact carrier. The first and second plug connection ends respectively have first and second plug contact connection patterns for connecting first and second data connectors. The contact carrier is arranged between the plug connection ends and carries two first contacts and two second contacts respectively forming the first and second plug contact connection patterns. One of the first contacts in each case is electrically conductively connected to one of the second contacts via a contact connection section. The first and second contacts are surrounded at least in sections respectively by electrically insulating first and second carrier bodies having first and second dielectric constants ε.sub.R1, ε.sub.R2. Outer circumferential surfaces of the carrier bodies bear against an inner wall surface of the plug shield at least in sections.

One example includes a signal connector system. The system includes a first connector comprising a first housing and first contacts formed from a self-passivating transition metal and configured to conduct an AC signal. The system also includes a second connector comprising a second housing and second contacts formed from the self-passivating transition metal and configured to electrically couple to a respective one of the first contacts to conduct the AC signal. The first and second housings can be coupled to enclose the signal connector and to create at least one fluid-filled channel between each of the electrically-connected first and second contact pairs in response to fastening the first and second connectors while submerged in a respective fluid to provide a resistive path in the at least one fluid-filled channel for providing signal isolation between each of the electrically-connected first and second contact pairs.

A dielectric member for controlling impedance for use in an electrical connector. The dielectric member including a housing made of dielectric material and a dielectric rib. The dielectric rib extends from a conductor receiving end of the housing in a direction away from a mating end. The rib is spaced equidistant from each of the conductor receiving openings. The rib extends in a direction which is essentially parallel to a longitudinal axis of the housing. Conductor engaging surfaces are provided on the rib, with a first conductor engaging surface of the conductor engaging surfaces being opposed to a second conductor engaging surface of the conductor engaging surfaces. The first conductor engaging surface and the second conductor engaging surface are spaced apart a distance, wherein the impedance of the conductors proximate the rib is approximately the same as the impedance of the cable.

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.

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.
