A high-speed communication connector capable of improving transmission quality and of controlling transmission characteristics is disclosed. The connector is a board-to-board-type connector for high-speed data communication in band of 10 to 25 GHz, and is constructed so as to reduce signal interference by virtue of a finger body having a PCB structure and shield structures between signal lines of a receptacle body filled with a dielectric material and to realize matching between impedances by virtue of the dielectric material and the signal lines.

An electrical connector for high frequency data signal transmission includes a housing, at least one tunnel extending through the housing and at least one electrical lead extending through the at least one tunnel. At least a portion of the electrical lead in the tunnel is embedded in a surrounding material having a relative permittivity which is less than 2.

An electrical connector assembly which has a housing formed of a first photocurable polymer composition. Signal contacts are positioned in the housing for transmitting signals at a determined signal speed. A dielectric constant of the photocurable polymer composition is tuned to have a higher or lower dielectric constant to be compatible with the desired signal performance characteristics of the signals transmitted over the signal contacts in the housing.

A connector housing includes a receiving chamber having a pair of opposite side walls, a support rib disposed in a lower portion of the receiving chamber and extending in the longitudinal direction, a row of first receiving compartments disposed in each of the pair of opposite side walls of the receiving chamber, and a partition wall disposed between each pair of adjacent first receiving compartments. The receiving chamber extends in a longitudinal direction and a height direction and is adapted to receive a mating connector. The row of first receiving compartments face the support rib and position a plurality of conductive terminals. Each partition wall extends from an outer side of the first receiving compartments in a lateral direction and is connected to the support rib.

A connector assembly for connecting a cable to an electrical component includes a plug unit and a mating plug unit, which each have an outer conductor element, an insulator element and an inner conductor element. The insulator element is disposed within the outer conductor element and includes an inner conductor channel in which the inner conductor element is disposed. The insulator element of the plug unit forms a plug profile that extends around the inner conductor channel and has at least one projection and/or depression. The insulator element of the mating plug unit forms a mating plug profile that corresponds to a negative of the plug profile. The plug unit and the mating plug unit are connectable to one another in such a way that the plug profile and the mating plug profile rest against each other, at least in some areas.

A coaxial terminal includes a signal terminal, a tubular ground terminal that covers the signal terminal, and an insulating member interposed between the signal terminal and the ground terminal. The signal terminal includes a main body that is covered by the insulating member, an upper contact piece that extends from the main body to +Z direction side, and a lower contact piece that extends from the main body to −Z direction side. The insulating member has an opening through which a part of the main body is exposed. A following formula (1) is satisfied:
L.sub.2≥½×L.sub.1  (1)
where L.sub.1 is a length of the insulating member along an axial direction of the coaxial terminal, L.sub.2 is a length of the opening along the axial direction.

A contact terminal includes a terminal shield, a contact carrier, and a contact element for conducting electrical signals of a high-frequency data transmission. The contact carrier retains the contact element in a fixed position within the terminal shield. The terminal shield has a discontinuity that affects an impedance of the contact element. At least one of the contact carrier and the contact element has an impedance control feature configured to adjust the impedance of the contact element to a predefined desired value according to a frequency of the data transmission.

A cable connector arrangement includes a cable connector and an electrical cable with a plurality of individual lines each having a respective insulation and electrical conductor. The connector may include a front section configured for connection to a mating connector, a rear section in which the individual lines are surrounded by a cable sheath, and a central section. The electrical conductors of two individual lines have a first mutual distance in the rear section and a greater, second mutual distance in the front section with the mutual distance being increased in the central section. At least one pressing means in the central section may press at least the two individual lines together such that their insulations undergo mechanical deformation in a region of common contact.
