An electrical connector includes a terminal module having a circuit board having first through eighth conductive traces sequentially arranged in a transverse direction and corresponding first through eighth terminals, the third terminal and the sixth terminal being configured for transmitting a pair of differential signals, the fourth terminal and the fifth terminal being configured for transmitting another pair of differential signals, the first through eighth conductive traces being respectively electrically connected to corresponding first through eighth terminals, each of the third conductive trace and the fifth conductive trace including a coupling portion, a size of the coupling portion in the transverse direction is larger than a size of the other part of the corresponding conductive trace in the transverse direction, wherein the coupling portion of the third conductive trace and the coupling portion of the fifth conductive trace overlap in an up and down direction to increase mutual coupling.

A compression connector comprises a connector body comprising an inner surface and a threaded clamp at least partially positioned within the connector body and configured to slide relative to the connector body. A contact cone is positioned within the connector body and comprises an outer surface configured to engage with the inner surface of the connector body. An insulator is positioned proximate the contact cone and defines an aperture. An inner conductor comprises a contact component comprising an inner conductor basket and a cylindrical portion extending from the conductor basket, and an interface component defining an opening configured to engage with the cylindrical portion of the contact component. The contact component, the interface component, and the insulator are held together such that they form a rigid three-piece assembly when the threaded clamp couples an end of a cable.

A connector assembly which controls impedance. The connector assembly includes a first metallic outer housing and a second metallic outer housing. The second metallic housing has a conductor receiving portion. A rib is formed in the conductor receiving portion, the rib extends in a direction which is parallel to a longitudinal axis of the second metallic outer shell. A terminal positioned in the connector assembly has a conductor receiving section and a mating terminal receiving section. The mating terminal receiving section has a lead-in portion and securing projections. At least one longitudinally extending opening is positioned about the circumference of the mating terminal receiving section, the opening reduces the cross section of the terminal. The opening provides impedance tuning to allow for a defined pitch of the terminal to be maintained without an impedance drop because of the close proximity of the terminal to an adjacent terminal.

An electrical connector includes an insulating body and multiple differential signal terminal pairs, each having two differential signal terminals. Each differential signal terminal has a main body portion, a strip connecting portion extending upward from an outer side of the main body portion, an elastic arm extending upward from the main body portion, and a contact portion extending upward from the elastic arm. A through slot runs through the elastic arm, forming an inner elastic arm and an outer elastic arm at two opposite sides of the through slot. The outer elastic arm is adjacent to the strip connecting portion. A consistent pitch is formed between the contact portions of the differential signal terminals. A first distance between two adjacent inner elastic arms in each differential signal terminal pair is less than a second distance between two adjacent outer elastic arms in two adjacent differential signal terminal pairs.

A circuit board for use in a modular electrical connector. The circuit board has a first surface and an oppositely facing second surface. Signal pathways are provided on the first surface. The signal pathways have signal pathway ends abutting a mounting end of the circuit board. First ground pathways are provided on the first surface. The first ground pathways are positioned adjacent at least one of the signal pathways. The first ground pathways have first ground pathway ends abutting the mounting end of the circuit board.

The positioning of the signal pathway ends, the first ground pathway ends and the second ground pathway ends abutting the mounting end reduces crosstalk between signal pairs.

An electrical plug-in connector for differential signal transmission, having an external conductor contact element, a dielectric and at least one internal conductor contact element pair for differential signal transmission. The dielectric extends along a longitudinal axis through the external conductor contact element. The internal conductor contact element pair has a first internal conductor contact element and a second internal conductor contact element which extend along the longitudinal axis through the dielectric. The external conductor contact element and/or the dielectric have a compensation geometry in order to compensate for an asymmetry of the internal conductor contact element pair with respect to the longitudinal axis. As an alternative or in addition, it is provided that the internal conductor contact element pair has a compensation geometry in order to compensate for an asymmetry of the external conductor contact element and/or of the dielectric with respect to the longitudinal axis.
