Description

  

  Tube de contact destiné à être glissé sur un fil d'aluminium,  et procédé<B>pour</B> sa fabrication.    La présente invention comprend un tube  de contact destiné à être glissé sur un fil  d'aluminium. Ce tube est caractérisé en ce  qu'il     présente    une     fente    en spirale sur     toute     sa longueur, ce qui le rend souple et lui per  met d'épouser un fil d'aluminium de forme  et de profil quelconques,     tout    en reposant sur  toute la surface du filet en formant un con  tact intégral avec celui-ci.  



       L'invention    comprend en outre un procédé  pour la fabrication dudit     tube,    caractérisé en  ce que l'on utilise un     ruban.    métallique que  l'on     eniroule    en spirale sur un mandrin.  



  Le -dessin     annexé    représente, à titre  d'exemple, une forme d'exécution du tube que  comprend l'invention, ainsi qu'une mise en       oeuvre    du procédé que comprend aussi l'in  vention.  



       Fig.    1     montre,        en,élévation,    un fragment  d'une forme d'exécution du tube que -com  prend l'invention, monté sur un fil de     section     circulaire.         Fig.    2 montre, à plus petite échelle, ledit       tube    monté sur un fil d'aluminium.  



       Fig.    3 est une vue analogue à la     fig.    2,  le tube étant représenté en coupe.  



       Fig.    4 montre un fil d'aluminium muni  dudit tube et placé sous une vis de serrage.       Fig.    5 montre un fil d'aluminium     re-          courb6afin    d'être placé sous une vis de     ser-          rage    et muni dudit tube.  



       Fig.    6 montre     en:    coupe le fil de la     fig.    à  et son tube de contact placés sous une vis de  serrage.  



       Fig.    7 montre un tube de contact glissé  sur un fil d'aluminium de section polygo  nale.  



       Fig.    8 illustre une mise en     couvre    du  procédé que     comprend        l'invention    et montre  un ruban au cours de son enroulement sur  un mandrin polygonal, qui peut être, par  exemple,     constitué    par le fil d'aluminium  devant recevoir ledit tube.  



  Le tube représenté     en;        fig.    1 est destiné  à être glissé sur un fil d'aluminium, afin      d'améliorer le contact de ce fil. Ce tube est  constitué en un métal ne formant pas de  couple électrique avec l'aluminium et n'atta  quant pas ce dernier. Il présente une     fente    en  spirale 1 sur toute sa longueur. Cette fente a  l'avantage de rendre le tube parfaitement  souple et lui permet d'épouser un fil d'alu  minium de forme et de profil quelconques       tout    en     reposant    sur     toute    la surface du fil et  en formant un contact intégral avec celui-ci.  



       La        fig.    2 montre le tube monté sur un fil  d'aluminium 2 de forme rectiligne et de sec  tion ronde.  



  La     fig.        3-est    une vue analogue à la fi--. 2,  mais dans     laquelle    le tube est représenté en  coupe.  



  Grâce à sa souplesse, le tube peut être  glissé sur un fil de forme quelconque, par  exemple sur un fil d'aluminium en forme de  crochet, comme représenté en     fig.    5, un tel fil  étant destiné à être serré sous une vis de ser  rage, comme le montre la     fig.    6.  



  La souplesse du tube permet de le, glis  ser ;sur un fil d'aluminium dont la section  est, par exemple,     carrée    ou rectangulaire, au  lieu d'être ronde. La     fig.    7 montre une forme  d'exécution du tube glissé sur un tel fil.  



  La.     fig.    8 illustre une forme d'exécution  du procédé que comprend l'invention, pour la  fabrication du tube.  



  Un ruban métallique est enroulé en spi  rale sur un mandrin 3 qui peut, par exemple,  être constitué par le fil d'aluminium sur le  quel le tube doit être glissé.  



  De     préférence,    on utilisera un mandrin  d'un diamètre plus petit que le diamètre du  fil sur lequel le tube devra être glissé. Aussi,  grâce à sa souplesse, le tube épousera parfai  tement le fil et fera corps avec lui.    Dans ses formes d'exécution préférées, le  tube sera. très mince, afin de ne pas augmen  ter sensiblement la section du fil d'alumi  nium sur lequel il sera glissé.  



  Dans une mise en     oeuvre    particulière du  procédé, le ruban     métallique    sera enroulé en  spires     jointives    de     façon    -à ce qu'il n'y ait pas  d'espace entre les spires.



  Contact tube intended to be slipped on an aluminum wire, and method <B> for </B> its manufacture. The present invention includes a contact tube intended to be slid over an aluminum wire. This tube is characterized in that it has a spiral slit along its entire length, which makes it flexible and allows it to follow an aluminum wire of any shape and profile, while resting on the entire surface. net by forming an integral contact with it.



       The invention further comprises a method for manufacturing said tube, characterized in that a tape is used. metal that is wound in a spiral on a mandrel.



  The appended drawing represents, by way of example, an embodiment of the tube which the invention comprises, as well as an implementation of the method which also comprises the invention.



       Fig. 1 shows, in, elevation, a fragment of an embodiment of the tube that -com takes the invention, mounted on a wire of circular section. Fig. 2 shows, on a smaller scale, said tube mounted on an aluminum wire.



       Fig. 3 is a view similar to FIG. 2, the tube being shown in section.



       Fig. 4 shows an aluminum wire provided with said tube and placed under a tightening screw. Fig. 5 shows an aluminum wire bent to be placed under a clamping screw and provided with said tube.



       Fig. 6 shows in: cut the wire of fig. à and its contact tube placed under a tightening screw.



       Fig. 7 shows a contact tube slipped on an aluminum wire of polygo nal section.



       Fig. 8 illustrates an implementation of the method that comprises the invention and shows a tape during its winding on a polygonal mandrel, which can be, for example, constituted by the aluminum wire to receive said tube.



  The tube shown in; fig. 1 is intended to be slipped on an aluminum wire, in order to improve the contact of this wire. This tube is made of a metal which does not form an electrical couple with the aluminum and does not attack the latter. It has a spiral slit 1 along its entire length. This slot has the advantage of making the tube perfectly flexible and allows it to match an aluminum wire of any shape and profile while resting on the entire surface of the wire and forming full contact with the latter.



       Fig. 2 shows the tube mounted on an aluminum wire 2 of rectilinear shape and round section.



  Fig. 3-is a view similar to fi--. 2, but in which the tube is shown in section.



  Thanks to its flexibility, the tube can be slipped on a wire of any shape, for example on an aluminum wire in the form of a hook, as shown in FIG. 5, such a wire being intended to be clamped under a clamping screw, as shown in FIG. 6.



  The flexibility of the tube makes it possible to slide it on an aluminum wire whose section is, for example, square or rectangular, instead of being round. Fig. 7 shows an embodiment of the tube slipped on such a wire.



  Fig. 8 illustrates an embodiment of the process that the invention comprises, for the manufacture of the tube.



  A metal tape is wound in a spiral on a mandrel 3 which may, for example, be constituted by the aluminum wire on which the tube is to be slid.



  Preferably, a mandrel will be used with a diameter smaller than the diameter of the wire on which the tube will have to be slid. Also, thanks to its flexibility, the tube will perfectly match the wire and become one with it. In its preferred embodiments, the tube will be. very thin, so as not to significantly increase the section of the aluminum wire on which it will be slipped.



  In a particular implementation of the method, the metal tape will be wound in contiguous turns so that there is no space between the turns.
