  • Patent number: 7758372
    Abstract: The invention concerns a connector designed to be fitted to a multi-conductor cable and which comprises at least one socket, a cable grip formed by a portion connected to the socket and a free portion articulated on the connected portion, and assembly means. The assembly means comprise a lever articulated around an articulation axis, held by the socket and distant from the articulation axis of the grip, wherein this lever has a curved end that may exert on the external surface of the free portion of the grip a thrust force which solicits the grip when closing in response to the application, on the lever, of a rotational torque around the articulation axis.

  • Patent number: 7721319
    Abstract: A system for distributing television signals comprises a first terminal which receives a coaxial cable, at least one second terminal which receives a twisted pair of conductors, and an amplifier system comprising a unit for selecting either a first slope or a second slope of increasing gain as a function of frequency between a signal present at the first terminal and a signal present at the second terminal. A method of distributing television signals includes a step of obtaining a system of the above kind, a step of determining a threshold for the length of the pair, and a step of selecting the first slope when the twisted pair has a length less than the threshold and the second slope when the twisted pair has a length greater than the threshold.

  • Publication number: 20080257582
    Abstract: The sleeve for an electric cable comprises two bodies (2, 3) and a hinge (4). Each body (2, 3) is flexible in the profile thereof, has, in the absence of mechanical stress, a position of rest in which it is curved whereas it is designed for being bent from the position of rest. The sleeve has an open position in which the bodies (2, 3) are separated from one another when in the position of rest, has a first stable closed position in which a first body (3) receives the second body (2) and has a second stable closed position in which the second body (2) receives the first body (3). The sleeve is designed for being deformed by folding the hinge (4) and to flex in the profile of these bodies (2, 3) in order to pass from the open position into one or other said stable closed positions.
