A housing of a connector includes a first section and a second section connected to the first section and extending from the first section. The first section has a first dielectric constant. The second section has a second dielectric constant that is less than the first dielectric constant.

A data cable plug connector for data transmission includes a plug body comprising a cable connection end, a plug connection end and a plug shield. The cable connection end has a first connection channel for a first insulated conductor, a second connection channel for a second insulated conductor, and a shield connection for a conductor shield. The plug connection end has a contact carrier with contact openings for receiving contacts which are connectable to the insulated conductors. The cable connection end has an impedance transmitter made of electrically conductive material disposed adjacent to the contact carrier, the connection channels being formed in the impedance transmitter, and at least one material that is electrically conductive at least in parts being formed between the connection channels channel. Openings of the connection channels facing the contact carrier open into the openings of the contact carrier.

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.

A shielding electrical terminal is presented herein. The shielding electrical terminal includes a securing portion that is configured to attach to an outer shield conductor of a shielded cable and a cylindrical mating portion having an inner surface configured to make electrical contact with a corresponding cylindrical shield terminal inserted within the mating portion. The inner surface of the mating portion defines a plurality of protrusions that extend from the inner surface.

A connector for use with high speed signals. The connector has a housing, which includes a base portion extending in a longitudinal direction and a tongue portion extending from the base portion in a mating direction perpendicular to the longitudinal direction. The housing has slots extending through the base portion to surfaces of the tongue portion and configured to hold terminals. The housing has a lossy material sized and shaped to couple with at least the portions of ground terminals held in the base portion along their lengths. The lossy material may protrude towards spaces between the portions of signal terminals held in the base portion along their lengths. The tail portions of the terminals may jog toward a plane that the lossy material extends. Such a connector may be used to meet signal integrity requirements in connectors designed for 64 Gbps and beyond.

A cable termination that provides low signal distortion even at high frequencies. Conductive elements of the cable are fused to edges of signal conductors in a cable connector or other component terminating the cable. For terminating a differential pair, the conductive elements of the cable may be terminated to opposing edges of a pair of signal conductors in the cable termination. The conductive elements may be shaped such that the spacing between signal paths passing through the conductive elements of the cable and into the signal conductors of the cable termination is uniform.

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.
