<p>The invention relates to a contact set for connecting a multi-pair communication cable having wire pairs, in particular individually shielded four wire pairs. The set comprises a male connector provided to be plugged into a female connector, the male connector comprising a first (1), a second (2), a third (3) and a fourth (4) pair of connection pins provided for being connected to corresponding wires of the wire pairs. According to the invention, the male connector further comprises a central (5) and a further (6) pairs of connection pins forming an aligned series of pins with the third and fourth pairs of pins, wherein the central pair is located in the middle of the series and the two pins of the further pair of pins are located on both sides of the central pair of pins, the third and fourth pairs of pins being each located at a respective extremity of the series. The central and further pairs of pins are respectively connected to electrical contacts (18, 19) connecting them, preferably by default, to the first pair and second pairs of pins, in such a manner that upon connection into a female connector of a first type ("category 7") having corresponding first and second pairs of pins, the electrical contacts are released, whilst upon connection into a standard RJ-45 female connector ("category 5 or 6'') consisting of four aligned pairs of pins mating in the series of first second, central and further pairs of pins, the electrical contacts are held. The electrical contacts may be operated automatically by means of a protrusion (8) or manually by means of a switch or protuberance (7). <IMAGE></p> |
