An electrical interconnection system comprising one or more insulative projecting members. The electrical interconnection system may comprise a first connector and a second connector. Each connector may comprise one or more projecting members extending along the mating direction. When the connectors are mated, the projecting member(s) may be configured to affect the impedance of the signal conductors of the connectors. In a partially mated position, the projecting member(s) may be configured to fill at least a portion of the region separating the connectors, thereby replacing air that might otherwise exist in that separation with a dielectric member. Because this dielectric constant is closer to what would be experienced in the fully mated position, the magnitude of the change in impedance as a result of separation may be less than had the entire space been filled with air.

A terminal module includes: a conductive terminal to be contacted and cooperated with a mating terminal, the conductive terminal including a base and a mating end at a front of the base, the mating end including a contact portion to be contacted and cooperated with the mating terminal and a front end portion at a front end of the contact portion; and a plastic part, wherein the plastic part is arranged at the front end portion so that a gap between the contact portion of the conductive terminal and the mating terminal is less than 0.1 mm after cooperated.

An electrical connector includes an insulating body having a first insulator and a second insulator, and multiple terminals disposed on the insulating body. A gap space is formed between the first and second insulators. The gap space is filled with air. Each terminal has a mating segment located above the first insulator, a first fixing segment extending downward from the mating segment and insert-molded into the first insulator, a connecting segment extending downward from the first fixing segment and exposed to the gap space, a second fixing segment extending downward from the connecting segment and insert-molded into the second insulator, and a positioning segment extending downward from the second fixing segment and located below the second insulator. The width of the first and second fixing segment is less than the width of at least one of the mating segment, the connecting segment and the positioning segment.

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.

For a connector including a terminal and a housing into which the terminal is inserted, the degrees of freedom of design are raised for a retaining portion that retains the terminal, and adjustment of connector characteristics such as impedance is facilitated.

A connector is configured including terminals (signal terminals and power source terminals) and housings into which the terminals are inserted. The housings are configured including a first housing (the fitting housing) and a second housing (the mounted housing). The first housing includes first side retaining portions (signal terminal retaining portions and power source terminal retaining portions of the fitting housing) that retain portions of the terminals. The second housing includes second side retaining portions (signal terminal retaining portions and power source terminal retaining portions of the mounted housing) that retain other portions of the terminals.

An electrical connector comprising a terminal module and a housing. The terminal module comprises a plurality of terminals. The housing comprises an accommodating groove in which the terminal module is disposed. The accommodating groove comprises a first groove wall and a second groove wall opposite to the first groove wall. The terminal module is disposed between the first groove wall and the second groove wall. A wall surface of the first groove wall and a wall surface of the second groove wall are disposed close to a structural contour of the plurality of terminals. Since the groove wall is designed as a wall surface close to the structural contours of the plurality of terminals, the dielectric constant of the groove wall can be greater than that of the air. In this way, the relative dielectric constant around the plurality of terminals would be increased to reduce the impedance.

An electrical connector includes first and second adjacent electrical contacts that each define respective first and second mating ends, the first mating end of a first one of the first and second adjacent electrical contacts defines a first contact surface, the second mating end of a second one of the first and second adjacent electrical contacts defines a second contact surface electrically isolated from the first contact surface; and a dielectric material positioned between the first and second adjacent electrical contacts. When a mating connector applies a force to the first contact surface and the second contact surface, the first and second mating ends and the dielectric material all move in a first direction.

A plug connector having a contact support (2), wherein at least one contact chamber is provided in the contact support (2) and a contact partner (3) is inserted into the contact chamber and primarily locked therein, wherein each contact partner is allocated a throughgoing hole on one side of the contact support (2) for the primary latch formation and so as to increase the transmission rate, and a further single throughgoing hole is provided on the opposite side of the contact support (2), wherein the throughgoing holes have an elongated rectangular shape.
