Definitions

  • the contact member then produced by cutting and folding, has an S-shaped structure.
  • these lips are each connected respectively to the shells to which they belong by a constriction, which, radially affecting one and the other of these shells, leads to a reduction in their spacing relative, and, on the other hand, at the free end of the floating shell, they are jointly bevelled at an angle, by a chamfer, counting from the base of this constriction.
  • the two elements E, E ′ constituting the contact member 11 are each respectively leaning against one another by a flange 20 extending on either side of the 'axis A.
  • the two lips L1, L2 which it comprises for the definition of a slot F each belong respectively to two shells C1, C2, which each generally form at least one portion of cylinder, and one of which at least, said here for simple convenience floating shell, extends circularly in overhang from a root generator and is thus elastically deformable radially around the latter.
  • the height H of the floating shell C2 decreases steadily from its root generatrix G to its free end 21.
  • the floating shell C2 also has, at its free end 21, a height H1 which is not zero.
