  • Patent number: 8128432
    Abstract: The insert includes at least three contacts having essentially linear parts and at least one three-pole capacitance between three of the contacts. One of the contacts of each three-pole capacitance is connected to a central armature. A first dimension of the central armature, in the direction perpendicular to the substantially linear parts, is greater than a second dimension, in a direction parallel to the substantially linear parts, the second dimension defining the widths of the zones of the central armature. The mean width of the central armature, between the zones where it faces other armatures, connected to the other contacts of the three-pole capacitance, is greater than one third of the mean length of the central armature in these regions. Preferably, in at least one three-pole capacitance, the mean width of the central armature between the regions where it faces the lateral armatures is greater than one third of the distance between the lateral armatures.

  • Patent number: 7985100
    Abstract: A connector includes an insert including contacts having free parts to receive homologous flat contacts of a plug. The insert further includes a rotation axis about which the insert can be rotated and spring means urging the insert toward the position that it assumes when no plug is present. The insert can include, at the sides, long curved contacts and, in a central portion, shorter curved contacts, the points of contact of the contacts of the insert with the flat contacts of a plug being substantially aligned over all the contacts.

  • Patent number: 7905743
    Abstract: The invention relates to a socket to be mounted on a multi-conductor cable and including a removable comb (1) having a central channel (5) extending therethrough, a connection terminal block (2), and a screw (3) and nut (4) assembling device. According to the invention, the screw (3) is fixedly mounted on the comb (1) for axial translation therewith and capable of rotation relative to the comb about the axis (X) of the socket, the terminal block (2) including two columns (22) that prevent the rotation of the comb about the axis (X) and in which helical notches (41) are formed that define a portion at least of the nut (4).

  • 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: 7625224
    Abstract: The invention concerns a connector for an armoured cable, this connector comprising a socket body and a conductive earthing member, the socket body being designed to receive a multi-conductor plug and comprising a wall element conformed so as to be in contact with this plug, and the earthing member comprising a band gripping the armouring of the cable and an elongate element electrically connecting the band to the socket body. According to the invention, the elongate element is flexible and the band takes the form of an open elastic clamp designed so as to be forcibly fitted on the armouring of the cable.
