Definitions

  • the present invention relates to a shape memory element for braid connection or shielding conductor of a cable on a conductor.
  • connection of the metallic braids constituting the shielding conductor of an electric cable, is generally carried out by means of a copper or copper alloy ring subjected to a magnetostriction treatment.
  • the metal braid having been previously suitably placed on the zone or rear part of the connector intended for this purpose, the aforementioned ring, surrounding the braid, is brought to this zone.
  • the magnetostriction treatment has the effect of causing sufficient shrinkage or contraction of the ring on the braid and thus ensures the electrical contact and the mechanical retention of the braid on the rear region of the connector.
  • this type of connector has the disadvantage of being unable to reuse the rings used, due to the absence of reversibility of the passage from the memorized state of shape allowing the mounting of the braid on the rear zone of the connector to the end state in which the electrical contact and the maintenance of the braid on the rear area of the connector are ensured.
  • this type of ring in any case only allows an overall radial deformation of the order of 8%, which, in certain cases, can cause inconvenience in use during assembly of the braided.
  • the present invention relates to the implementation of a shape memory element for braid connection on a connector which does not have the aforementioned drawbacks.
  • Another object of the present invention is the implementation of a shape memory element for braid connection on a connector capable of being reused after dismantling the connector.

  • the so-called transition temperature Ms is in fact the temperature at the start of transformation of the material in the crystallographic state of martensitic type.
  • the material can also be brought, preferably, to a temperature situated below its end of martensitic state temperature Mf.
  • the second memorized shape state II allows engagement and / or disengagement of the braid and the rear area of the aforementioned connector.
  • the wound element 3 is shown as formed, without limitation, so as to constitute a substantially cylindrical winding.
  • the winding can consist of turns of the same diameter.

  • the rear region or part of the connector 20 can be provided with protruding parts intended to ensure good electrical contact and good mechanical support of the braid 1 thereon.
  • Figure 1b there is shown by way of example, the projecting parts of the area or rear part 20 of the connector 2, in the form of a sharp edge thread, in which the metal wires constituting the braid 1 can be engaged by jamming, under the effect of the pressure exerted by the element when the latter has returned to its state of memorized form I.

  • the rod is then brought to room temperature, with or without quenching, so as to allow the actual shaping.
  • the actual shaping that is to say the shaping in the final state constituting the final state, beyond the transition temperature Ms of the material, is then carried out by plastic deformation of the rod at room temperature.

  • the element 3 can of course be introduced into the die, by traction.
  • the amplitude of the stress applied to the winding 3 is chosen such that it does not substantially exceed the elastic deformation limit of the winding at the temperature above the transition temperature Ms. Then, the stress being maintained, the winding is cooled and brought to a temperature below its transition temperature Ms, and preferably below its end of martensitic state temperature Mf.
  • the winding 3, under the effect of the stress deforms by plasticity of deformation, in the direction imposed by the stress. It deforms by a number of turns per rotation of the turns which depends of the constraint imposed, of the characteristics of the winding including the initial number of turns, and the modification of the diameter of the turns results in a change in the number of turns or turns, without appreciable change in the length of the winding 3.
  • the winding 3 is then brought back to a temperature higher than the Ms temperature, the stress being maintained.
  • the aforementioned education process does not prejudge the deformation applied to the winding 3.
  • the tool allowing the implementation of the education process previously designated by a sector, can be replaced by a cylindrical element mounted for rotation and translation on a threaded axis, and on which a motor torque is applied.
  • the setting in motion in rotation and in translation of the cylinder, at least one end of the winding 3 being integral with the cylinder, has the effect of causing the corresponding education of the winding 3, along a path resulting from the composition of the movements of rotation and translation mentioned above.
