Connector provided with contacts mounted in an adapted insulator

A connector including a body to be mounted on a quadriaxially twisted cable and including at least four contacts and an insulator, said insulator receiving at a first end wires of the cable, and receiving sockets of said contacts at a second end of the insulator, each wire is able to be connected with a respective socket, characterized in that said insulator includes channels in which the wires and the sockets extend, and in that a geometry of symmetrical disposition of the channels in the insulator is determined according to a characteristic impedance of the cable, and

• characterized in that the insulator includes three parts, a rear part around the wires of the cable, a central part in a region of which the wires of the cable are linked to the contacts, and a front part in a mating region of the contacts, and
• characterized in that the rear part includes a socket and an optional intermediate piece, such that an inner diameter of the socket and the intermediate piece are substantially identical to the diameter of the twisted wires.
