Abstract: An insert for a multi-channel connector comprising a plurality of main contacts for carrying signals, said plurality of main contacts being arranged according to a main arrangement on a first face of said insert. The insert comprises a plurality of secondary contacts for carrying further signals, in particular for carrying data control signals. Said plurality of secondary contacts are arranged according to a secondary arrangement at empty spaces of said first face of said insert. Moreover, said secondary contacts are configured in such a way as to be operational and allow the carrying of said further signals when said insert for said multi-channel connector is coupled to a further reciprocal insert for a reciprocal multi-channel connector at respective first faces, said further reciprocal insert having the same main arrangement of a reciprocal plurality of main contacts and the same secondary arrangement of a reciprocal plurality of secondary contacts.

Abstract: The present invention relates to a multi-channel connector for cables for the transportation of both power lines and data signals, the connector comprising a plurality of phase contacts or hot/live contacts, a corresponding plurality of neutral contacts, and at least a corresponding plurality of earth contacts. The contacts are configured in such a way as to transmit electric current to power electrical devices. Furthermore, at least one of the earth contacts is a coaxial contact configured in such a way as to transmit data signals.

Abstract: A unipolar safety electric connector includes a male connector, shell, and a female connector shell, corresponding male and female inner electric contacts being provided within the male and female connectors, the female connector shell providing on its outer portion a “L” shaped guide groove, having one arm along the longitudinal coupling direction of the shells and the other arm along the transverse direction, a key being insertable within the “L” shaped groove, the key being provided on the edge of the male connector shell, the key, once introduced longitudinally at the bottom of the “L” shaped guide groove, engaging, by rotation of one shell with respect to the other one, with the transverse arm of the “L” shaped guide groove.

Abstract: A self-propelled member or carriage runs along a stationary surface-conducting cable formed of alternately disposed conducting and insulating turns. The carriage is provided with a rotor extending around the cable and having contacts in a conductive relation with the conducting turns of the cable. At least two pulleys are rotatably mounted to the carriage with the cable interposed between the pulleys. An electric motor is operatively electrically connected to the contacts of the rotors and is drivingly connected to the pulleys. Electric power is transmitted from the cable by the rotor to the motor whereupon the motor drives the pulleys to propel the carriage along the cable.
