Patent number: 8128432Abstract: 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.Type: GrantFiled: July 28, 2009Date of Patent: March 6, 2012Assignees: Legrand France, Legrand SNCInventors: Jean-Marc Jaouen, Didier Revol, Vincent Laroche, Nathalie Foratier, Jean-Pierre Cousy

Patent number: 7985100Abstract: 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.Type: GrantFiled: July 25, 2008Date of Patent: July 26, 2011Assignees: Legrand France, Legrand SNCInventors: Jean-Marc Jaouen, Didier Revol, Vincent Laroche, Nathalie Foratier

Patent number: 7758372Abstract: 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.Type: GrantFiled: November 11, 2008Date of Patent: July 20, 2010Assignees: Legrand France, Legrand SNCInventors: Jean-Marc Jaouen, Didier Revol, Vincent Laroche, Nathalie Foratier

Patent number: 7721319Abstract: 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.Type: GrantFiled: April 30, 2004Date of Patent: May 18, 2010Assignee: Legrand FranceInventor: Vincent Laroche
