    Abstract: A mechanical assembly of a multi-strand cable including a plurality of strands and a substrate, the plurality of strands being aligned at the substrate in a first direction and the substrate having a convex edge in a plane perpendicular to the first direction. The plurality of strands is assembled on the substrate by swaging the strands around the convex edge, leading to the deformation of a portion of the strands around said convex edge. The substrate also includes an opening in a plane substantially parallel to the first direction, the edge of which forms at least one portion of the convex edge. The swaging operation is carried out on the portion of the strands positioned between the edges of the opening such that a portion of the plurality of punched strands passes through the opening and projects around the convex edge onto the top and bottom sides thereof.

  • 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.
