An electrical connector includes a first set of conductors, a first overmolding in physical contact with a body portion of each of the first set of conductors, a second set of conductors, a second overmolding in physical contact with the body portion of each of the second set of conductors, and a spacer in contact with the first overmolding and the second overmolding. A gap is present between the spacer and at least one of the first set of conductors and a gap between the spacer and at least one of the second set of conductors.

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.

A shield connector is provided with a dielectric 40 including a plurality of accommodation chambers 44 defined in a width direction by a separation wall portion 43, and a plurality of inner conductors 21 having a shape elongated in a front-rear direction and individually accommodated in parallel in the plurality of accommodation chambers 44. The separation wall portion 43 is formed with a front opening 53 and a rear opening 60 for interposing air layers between the accommodation chambers 44 adjacent via the separation wall portion 43.

An electrical connector includes a bracket having a plurality of mating frames arranged side by side in a lateral direction and opening forward and plural transition modules inserted forward to be at least partially accommodated in the mating frame, wherein the bracket defines plural heat dissipation grooves each located between two adjacent frames and plural heat dissipation fins each located in a corresponding heat dissipation groove, the heat dissipation groove opening through in a front-rear direction.

A connector includes multiple ground terminals, multiple signal terminals, a cable and a ground assembly. The cable includes multiple ground wires and multiple signal wires. The ground assembly includes a plate and multiple protrusion structures. Each protrusion structure is arranged spacedly and extended from the plate. A top of each protrusion structure is higher than a surface of the plate. Each ground wire is electrically connected with each ground terminal and each protrusion structure. Each signal wire is electrically connected with each signal terminal. Each signal wire is formed between any two of the protrusion structures adjacent to each other. Therefore, high-speed transmission of digital signals may be undistortedly implemented.

A plug connector for symmetrical signal transmission includes: at least two connection contacts on a connection side of the plug connector; at least two plug contacts on a plugging side of the plug connector on an opposite side to the connection side; at least two conductors, each of which connects one connection contact to one of the plug contacts in an electrically conductive manner; and a dielectric enclosure of the at least two conductors, the dielectric enclosure having at least one clearance between the conductors.

A terminal structure of a high-frequency signal connector and a manufacturing method thereof, in which multiple first terminals and multiple second terminals, multiple excavation areas and multiple trimming lines are trimmed from a tape, the first terminals and the second terminals are arranged alternately, each of the trimming lines is located between one of the first terminals and one of the second terminals that are disposed next to each other, followed by stamping the first terminals and the second terminals to form a first terminal set and a second terminal set. The first terminals and the second terminals are formed simultaneously on a single tape, and in turn, the period for fabricating dies and developing dies may be reduced, and less metal tapes is wasted after blanking of the first terminals and the second terminals, in order to decrease processes and reduce a manufacturing cost of the connector effectively.

An electrical socket connector includes: an insulation body, first terminals, second terminals, and a metal casing. The insulation body includes a basal part and a tongue plate connected to the basal part. The first terminals each include a first contact part and the second terminals each include a second contact part. Each first contact part comprises a first front contact part and a first rear contact part. Each second contact part comprises a second front contact part and a second rear contact part. The tongue plate defines first and second recesses. Each first recess is positioned between two adjacent first front contact parts. Each second recess is positioned between two adjacent second rear contact parts.
