Description

La présente invention concerne une ligature pour la fixation d'un câble dans la gorge supérieure d'un isolateur rigide.The present invention relates to a ligature for fixing a cable in the upper groove of a rigid insulator.

On connaît par la. demande de brevet français n° 81 15 205 déposée le 5 août 1981 par la Demanderesse une ligature pour la retenue d'un câble dans la gorge latérale d'un isolateur rigide.We know by. French patent application no. 81 15 205 filed on August 5, 1981 by the Applicant a ligature for retaining a cable in the lateral groove of a rigid insulator.

Elle comporte deux branches sensiblement symétriques par rapport à un plan de symétrie de l'isolateur orthogonal au câble ; chaque branche présente une partie intermédiaire en arc de cercle dont le rayon de courbure est sensiblement celui du fond de la gorge latérale, passe dans un anneau commun aux deux branches, puis est enroulée en spirale autour du câble. L'autre extrémité de chacune des branches a sensiblement la forme d'une boucle, les deux boucles étant disposées de part et d'autre d'une pièce logée dans ladite gorge, et l'ensemble étant maintenu par un moyen de serrage.It comprises two branches which are substantially symmetrical with respect to a plane of symmetry of the insulator orthogonal to the cable; each branch has an intermediate part in an arc, the radius of curvature of which is substantially that of the bottom of the lateral groove, passes through a ring common to the two branches, then is wound in a spiral around the cable. The other end of each of the branches has substantially the shape of a loop, the two loops being arranged on either side of a part housed in said groove, and the assembly being held by a clamping means.

Selon un mode d'exécution, chaque branche est constituée par au moins un fil métallique replié en son milieu de manière à former ladite boucle. Après celle-ci, les deux fils métalliques peuvent être solidarisés l'un à l'autre formant ainsi un ruban qui est spiralé autour du câble.According to one embodiment, each branch is formed by at least one metal wire folded in the middle so as to form said loop. After this, the two metal wires can be joined to one another, thus forming a ribbon which is spiraled around the cable.

Le but de la présente invention est d'adapter la ligature préeé- dente à un isolateur dont le diélectrique présente une gorge latérale et une gorge supérieure, le câble étant situé dans la gorge supérieure.The object of the present invention is to adapt the preceding ligature to an insulator, the dielectric of which has a lateral groove and an upper groove, the cable being located in the upper groove.

L'invention a pour objet une ligature pour la retenue d'un conducteur électrique dans la gorge supérieure d'un isolateur rigide présentant également une gorge latérale, comportant deux branches sensiblement symétriques par rapport à un plan de symétrie de l'isolateur orthogonal audit câble, chaque branche présentant sa première extrémité sous la forme d'une attache spiralée pour ledit câble, caractérisée par le fait que la seconde extrémité de chaque branche a sensiblement la forme d'une boucle et est maintenue dans la gorge latérale de l'isolateur par un moyen de serrage, la première extrémité de la branche destinée à être spiralée sur le câble passant au travers d'un premier anneau logé dans la gorgé latérale de l'isolateur puis dans un second anneau logé dans la gorge supérieure.The subject of the invention is a ligature for retaining an electrical conductor in the upper groove of a rigid insulator also having a lateral groove, comprising two branches substantially symmetrical with respect to a plane of symmetry of the insulator orthogonal to said cable , each branch having its first end in the form of a spiral attachment for said cable, characterized in that the second end of each branch has substantially the shape of a loop and is held in the lateral groove of the insulator by a clamping means, the first end of the branch intended to be spiraled on the cable passing through a first ring housed in the lateral groove of the insulator then in a second ring housed in the upper groove.

Selon un mode d'exécution, chaque branche est constituée par au moins un fil métallique replié en son milieu de manière à former ladite boucle.According to one embodiment, each branch consists of at least one metal wire folded in the middle so as to form said loop.

Selon une caractéristique de l'invention, le premier anneau occupe sensiblement une demi-circonférence de ladite gorge latérale.According to a characteristic of the invention, the first ring occupies substantially a half-circumference of said lateral groove.

Selon une autre caractéristique, les anneaux sont constitués par repli d'un fil métallique et à chaque extrémité desdits anneaux, il y a superposition d'au moins un repli en épingle à cheveux et d'une spire ouverte.According to another characteristic, the rings are formed by folding a metal wire and at each end of said rings, there is a superposition of at least one hairpin fold and an open turn.

Avantageusement les parties extrêmes du fil métallique formant les anneaux sont légèrement cintrées de manière à ne pas faire saillie.Advantageously, the end portions of the metal wire forming the rings are slightly curved so as not to protrude.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description suivante d'un mode de réalisation en référence au dessin annexé dans lequel :

  • - la figure 1 montre schématiquement en perspective un isolateur muni d'une ligature selon l'invention, portant un câble dans sa gorge supérieure,
  • - la figure 2 est une vue de dessus très schématique de la ligature de la figure 1, l'isolateur n'étant pas représenté, le câble ayant été coupé dans la partie centrale pour une meilleure compréhension du dessin,
  • - la figure 3 montre plus en détail un anneau faisant partie de la ligature selon l'invention.
Other characteristics and advantages of the invention will appear during the following description of an embodiment with reference to the appended drawing in which:
  • FIG. 1 schematically shows in perspective an isolator provided with a ligature according to the invention, carrying a cable in its upper groove,
  • FIG. 2 is a very schematic top view of the ligature of FIG. 1, the insulator not being shown, the cable having been cut in the central part for a better understanding of the drawing,
  • - Figure 3 shows in more detail a ring forming part of the ligature according to the invention.

La ligature est en fil formant ressort, préférentiellement en acier inoxydable ou en alumoweld, et se compose de deux branches 5 terminées à une extrémité par une boucle 6 et à l'autre par une partie en spirale 7. Un premier anneau 8 incurvé en demi-cercle est disposé dans la gorge latérale de l'isolateur, ses extrémités étant sensiblement diamétralement opposées. Un deuxième anneau 9 de forme allongée est disposé dans la gorge supérieure. Chaque branche 5 traverse une boucle de l'anneau 8 et la boucle de l'anneau 9 correspondante.The ligature is made of spring wire, preferably made of stainless steel or alumoweld, and consists of two branches 5 terminated at one end by a loop 6 and at the other by a spiral part 7. A first ring 8 curved in half -circle is arranged in the lateral groove of the insulator, its ends being substantially diametrically opposite. A second ring 9 of elongated shape is arranged in the upper groove. Each branch 5 crosses a loop of the ring 8 and the loop of the corresponding ring 9.

Les anneaux peuvent être constitués par repli d'un fil métallique, et à chaque extrémité il y a superposition d'au moins un repli en épingle à cheveu et d'une spire ouverte.The rings can be formed by bending a metal wire, and at each end there is a superposition of at least one fold in hairpin and an open turn.

La figure 3 illustre un tel anneau.Figure 3 illustrates such a ring.

A chaque extrémité le fil métallique constituant l'anneau forme un repli 22, 23 en épingle à cheveu qui est superposé avec une spire ouverte 24, 25. Le changement de direction de l'attache du câble se fait donc en prenant appui sur deux sections du fil de l'anneau, ce qui diminue le risque d'endommagement de la ligature.At each end, the metal wire constituting the ring forms a fold 22, 23 in a hairpin which is superimposed with an open turn 24, 25. The change of direction of the cable tie is therefore made by resting on two sections ring wire, which reduces the risk of damage to the ligation.

En outre les deux parties extrêmes 26, 27 du fil formant l'anneau 1 sont légèrement cintrées de manière à se trouver sensiblement dans un même plan vers "l'intérieur" de l'anneau, pour que les pointes extrêmes 28, 29 ne blessent ni le câble, ni le verre de l'isolateur. Le fil utilisé pour constituer l'anneau peut être de l'alumoweld (aluminium + acier), ou de l'acier inoxydable, ou de l'Almelec.In addition, the two end parts 26, 27 of the wire forming the ring 1 are slightly bent so as to lie substantially in the same plane towards the "inside" of the ring, so that the end points 28, 29 do not injure neither the cable nor the insulator glass. The wire used to constitute the ring can be alumoweld (aluminum + steel), or stainless steel, or Almelec.

De même, chaque branche de la ligature peut être constituée par un fil de même nature replié en son milieu de manière à former la boucle 6. Après celle-ci, les deux fils métalliques peuvent être solidarisés, formant ainsi un ruban qui est spiralé autour du câble 10.Similarly, each branch of the ligature can be formed by a wire of the same kind folded in the middle so as to form the loop 6. After this, the two metal wires can be joined, thus forming a ribbon which is spiraled around cable 10.

Ainsi que représenté sur les figures 1 et 2, le moyen de serrage destiné à maintenir les boucles dans la gorge latérale de l'isolateur comprend une tige 2 filetée à ses extrémités et des écrous 11. Eventuellement, cette tige filetée peut porter au moins une pièce en élastomère prenant avantageusement appui dans le fond de la gorge latérale de l'isolateur.As shown in Figures 1 and 2, the clamping means for holding the loops in the lateral groove of the insulator comprises a rod 2 threaded at its ends and nuts 11. Optionally, this threaded rod can carry at least one elastomer part advantageously supported in the bottom of the lateral groove of the insulator.

Comme dans le cas de la ligature décrite dans la demande de brevet français n° 81 15 205 précitée cette pièce en élastomère peut . être formée par un cylindre de section appropriée.As in the case of the ligature described in the aforementioned French patent application No. 81 15 205, this elastomer part can. be formed by a cylinder of appropriate section.

On pourrait également utiliser dans un but d'économie plusieurs rondelles présentant des diamètres différents de manière à épouser sensiblement le fond de la gorge latérale.One could also use, for the purpose of economy, several washers having different diameters so as to substantially match the bottom of the lateral groove.

Pour la mise en oeuvre du dispositif conforme à l'invention, on place celui-ci desserré sur l'isolateur, le câble 10 vient sur l'anneau 9, les parties spiralées 7 des branches 5 sont enroulées autour du câble ; on serre les écrous 11, ce qui a pour effet de bloquer dans la gorge latérale la partie de la ligature située entre la tige 2 et l'anneau 8, et simultanément d'appliquer l'anneau 9 contre la gorge supérieure de l'isolateur et de maintenir le câble 10 contre cet anneau 9.For the implementation of the device according to the invention, place it loosened on the insulator, the cable 10 comes on the ring 9, the spiral parts 7 of the arms 5 are wound around the cable; the nuts 11 are tightened, which has the effect of blocking in the lateral groove the part of the ligature located between the rod 2 and the ring 8, and simultaneously applying the ring 9 against the upper groove of the insulator and hold the cable 10 against this ring 9.

L'invention présente en particulier les avantages suivants :The invention has in particular the following advantages:

Le dispositif, empêche les déplacements oscillatoires relatifs du câble et de la ligature par rapport au diélectrique et évite donc son usure ainsi que celle du câble et de la ligature.The device prevents relative oscillatory movements of the cable and the ligature with respect to the dielectric and therefore prevents its wear as well as that of the cable and the ligature.

Il permet d'avoir même moyen de serrage pour la disposition du câble 10 soit dans la gorge latérale, soit dans la gorge supérieure.It makes it possible to have the same clamping means for the arrangement of the cable 10 either in the lateral groove or in the upper groove.

Il assure une meilleure retenue résiduelle du câble sur l'isolateur en cas de fragmentation de sa tête.It ensures better residual retention of the cable on the insulator in the event of fragmentation of its head.

En supprimant le jeu entre ligature et diélectrique, il donne de meilleures performances à l'égard des perturbations radiophoniques.By eliminating the play between ligature and dielectric, it gives better performances with regard to radio disturbances.

On peut remplacer un isolateur sans avoir à dégager la ligature du câble et donc sans avoir à refaire le réglage de la ligne et cette opération est possible sous tension.You can replace an isolator without having to release the cable tie and therefore without having to redo the line adjustment and this operation is possible under voltage.

Bien entendu l'invention n'est pas limitée aux modes de réalisation décrits et représentés qui n'ont été donnés qu'à titre d'exemples.Of course, the invention is not limited to the embodiments described and shown which have been given only by way of examples.

En particulier, on peut sans sortir du cadre de l'invention, apporter des modifications de détail, changer certaines dispositions, ou remplacer certains moyens par des moyens équivalents.In particular, without departing from the scope of the invention, it is possible to make detailed modifications, change certain provisions, or replace certain means with equivalent means.
