A modular high speed, high density electrical connector configurable for use in multiple configurations, including a direct attach orthogonal configuration. The connector is assembled with modules that include shielded pairs of signal conductors with mating ends that are rotated approximately 45 degrees with respect to intermediate portions of the signal conductors. The connector may have a mating interface with receptacles in one connector and pins in the mating connector. The pins may be small diameter and may be implemented with superelastic wires so as to resist damage despite having very small effective diameter. A compact mating interface resulting from small diameter mating contact portions may enable other portions of the connector, including the shielding surrounding the signal conductors to be smaller, which may raise the resonant frequency of the connector and extend its bandwidth.

An electrical connector includes: an insulating body; and a first row of terminals and a second row of terminals housed in the insulating body, each terminal in the first row of terminals having a tail portion, a contact portion, and a body portion, the first row of terminals including a signal terminal pair having a pair of signal terminals and a ground terminal arranged on one side of the signal terminal pair, wherein a first center distance between the contact portions of the signal terminal pair is different from a second center distance between the contact portion of the ground terminal and the contact portion of an adjacent signal terminal.

An electrical connector is used to electrically connect a first component and a second component, including: an insulating body, having an insertion slot for the first component to insert backward therein; multiple terminals, having at least one pair of first signal terminals. Each terminal has a contact portion and a tail portion provided in the front-rear direction. The contact portion is provided relatively in front of the bottom surface and protrudes into the insertion slot to be electrically connected to the first component. The tail portion is electrically connected to the second component. Each terminal further has a connecting portion located between the contact portion and the tail portion. An insulating block is used to fix the terminal. The connecting portion of each terminal extends forward from the front surface of the insulating block and passes beyond the bottom surface. A portion of the connecting portion of each terminals not passing forward beyond the bottom surface is defined as an adjusting portion. A medium between the two adjusting portions of each pair of first signal terminals is completely a first medium. A dielectric coefficient of the first medium is less than a dielectric coefficient of the insulating body.
