Description

  

  Borne de     traversée    du     type        condensateur       La présente invention a pour objet une  borne de traversée du type condensateur, com  prenant un manchon en     matière    moulée.  



  Dans une telle borne de traversée, il est  dangereux de prévoir dans le manchon en ma  tière moulée un cylindre     métallique    lui confé  rant la propriété     d'électrode        condensateur,    car  il en résulte des tensions     internes,    lors des  échauffements par exemple,     pouvant        produire     des fissures.  



  La borne de traversée suivant l'invention  est caractérisée en ce que l'effet de capacité est  obtenu au moyen d'une électrode constituée  par une toile métallique en forme de cylindre  insérée dans le     manchon.     



  La     figure    du     dessin        annexé        représente,    à  titre d'exemple, une forme d'exécution de la  borne de traversée faisant l'objet de     l'inven-          tion.     



  L'enveloppe à traverser d'un appareil élec  trique est désignée par E. La borne de traversée  comprend     un    manchon M en matière moulée  traversé par une tige conductrice T.         L'effet    de capacité est obtenu au moyen  d'une électrode t     constituée    par une toile mé  tallique, en forme de     cylindre    entourant la tige  T, et insérée dans le manchon M.

   L'électrode  t est reliée par un conducteur c à une     douille          métallique    a entourant un des boulons d'assem  blage de la borne à l'enveloppe E de l'appareil       électrique.    L'électrode t est donc reliée de cette  façon à la masse de     l'appareil.     



  Lors d'échauffements éventuels, la toile       métallique        constituant    l'électrode t peut se di  later avec le manchon     M,    sans y créer de ten  sions     dangereuses.  



  A capacitor-type feed-through terminal The present invention relates to a capacitor-type feed-through terminal, comprising a molded material sleeve.



  In such a feed-through terminal, it is dangerous to provide a metal cylinder in the molded material sleeve giving it the property of a capacitor electrode, since this results in internal stresses, during heating for example, which can produce cracks. .



  The feed-through terminal according to the invention is characterized in that the capacitance effect is obtained by means of an electrode constituted by a metallic wire in the form of a cylinder inserted in the sleeve.



  The figure of the appended drawing shows, by way of example, an embodiment of the feed-through terminal forming the subject of the invention.



  The casing to be passed through an electrical device is designated by E. The feed-through terminal comprises a sleeve M of molded material traversed by a conductive rod T. The capacitance effect is obtained by means of an electrode t constituted by a wire mesh, cylinder-shaped surrounding the rod T, and inserted into the sleeve M.

   Electrode t is connected by a conductor c to a metal sleeve a surrounding one of the bolts connecting the terminal to the casing E of the electrical apparatus. The electrode t is therefore connected in this way to the ground of the device.



  In the event of possible heating, the metal mesh constituting the electrode t can expand with the sleeve M, without creating dangerous voltages therein.
