Description

La présente invention concerne un prolongateur d'une âme d'un câble coaxial.The present invention relates to an extension of a core of a coaxial cable.

Elle concerne également un connecteur muni d'un tel prolongateur d'âme.It also relates to a connector provided with such a core extender.

Les âmes de câbles coaxiaux sont constituées, soit d'un tube étiré, ou soit actuellement d'un feuillard mince soudé longitudinalement. Les prolongateurs d'âme de l'art antérieur utilisés dans des câbles coaxiaux dont l'âme est constituée d'un tube étiré, ne conviennent plus pour les câbles fabriqués actuellement dont l'âme est constituée d'un feuillard mince soudé.The coaxial cable cores consist either of a stretched tube, or either currently of a thin strip welded longitudinally. The core extenders of the prior art used in coaxial cables whose core consists of a stretched tube, are no longer suitable for cables currently manufactured whose core consists of a thin welded strip.

Un tel prolongateur de l'art antérieur est décrit dans le document US-A-2 822 418. Ce prolongateur est constitué d'une douille cylindrique présentant sur une partie de sa longueur des fentes longitudinales délimitant des ailettes, l'autre partie étant une extrémité fermée munie en son centre d'un trou taraudé recevant une vis. Cette vis entraîne une bague conique qui écarte les ailettes pour serrer la douille contre l'âme de deux câbles. Mais la tête de cette vis n'est accessible que de l'intérieur et ceci impose que le prolongateur soit creux pour permettre le passage d'un tournevis.Such an extension device of the prior art is described in document US-A-2 822 418. This extension device consists of a cylindrical sleeve having, over part of its length, longitudinal slots delimiting fins, the other part being a closed end provided in its center with a tapped hole receiving a screw. This screw drives a conical ring which spreads the fins to clamp the sleeve against the core of two cables. But the head of this screw is only accessible from the inside and this requires that the extension is hollow to allow the passage of a screwdriver.

La présente invention a pour but de permettre le serrage de la vis par l'extérieur, et d'autoriser ainsi le raccordement de deux câbles de grande longueur ou l'utilisation de toutes formes possibles d'extrémités de reprise.The present invention aims to allow the tightening of the screw from the outside, and thus authorize the connection of two very long cables or the use of all possible forms of recovery ends.

La présente invention a pour objet un prolongateur d'une âme d'un câble coaxial, comprenant une douille cylindrique munie d'une extrémité rendue flexible par des fentes longitudinales, une vis de traction et un élément conique pour écarter la douille, caractérisé en ce qu'il comporte un écrou polygonal dont les arêtes sont introduites dans les fentes longitudinales de la douille, l'élément conique étant un cône faisant partie de l'extrémité flexible, cette extrémité flexible ayant un diamètre externe supérieur au diamètre interne de l'âme de telle sorte que l'introduction de la douille dans l'âme resserre cette extrémité flexible et que la rotation de la vis de traction, en butée sur l'âme, provoque la translation de l'écrou qui écarte et serre l'extrémité flexible sur la paroi intérieure de l'âme.The subject of the present invention is an extension of a core of a coaxial cable, comprising a cylindrical sleeve provided with an end made flexible by longitudinal slots, a traction screw and a conical element for spreading the sleeve, characterized in that that it comprises a polygonal nut the edges of which are introduced into the longitudinal slots of the sleeve, the conical element being a cone forming part of the flexible end, this flexible end having an external diameter greater than the internal diameter of the core so that the introduction of the sleeve into the core tightens this flexible end and that the rotation of the traction screw, in abutment on the core, causes the translation of the nut which spreads and tightens the flexible end on the inner wall of the soul.

Avantageusement, l'écrou est carré, ses quatre arêtes étant enfilées chacune dans une fente longitudinale.Advantageously, the nut is square, its four edges being each threaded into a longitudinal slot.

De préférence, une extrémité de la vis de traction est une extrémité cylindrique guidée dans un alésage de la douille.Preferably, one end of the traction screw is a cylindrical end guided in a bore of the sleeve.

Le connecteur selon l'invention, muni d'un prolongateur d'âme d'un câble comportant du centre vers sa périphérie, une âme centrale, une couche isolante, un conducteur extérieur et une couche isolante externe, est caractérisé en ce que l'autre extrémité de la vis de traction est une extrémité de reprise constituée de deux épaulements lisses.The connector according to the invention, provided with a core extension of a cable comprising from the center towards its periphery, a central core, an insulating layer, an outer conductor and an outer insulating layer, is characterized in that the another end of the traction screw is a recovery end made up of two smooth shoulders.

Avantageusement ce connecteur comporte un tube central enfilé sur l'épaulement lisse de l'extrémité de reprise.Advantageously, this connector comprises a central tube threaded on the smooth shoulder of the recovery end.

Il est décrit ci-après à titre d'exemple et en référence aux figures du dessin annexé, un prolongateur selon l'invention et un connecteur muni d'un tel prolongateur.

  • La figure 1 représente une vue éclatée du prolongateur.
  • La figure 2 représente le prolongateur au cours de sa mise en place dans l'âme du câble coaxial.
  • La figure 3 montre, en coupe suivant III de la figure 2, la forme particulière d'un écrou enfilé dans les fentes longitudinales de la douille du prolongateur.
  • La figure 4 représente le prolongateur dans sa position de serrage.
  • La figure 5 représente un connecteur d'un câble coaxial, muni d'un tel prolongateur d'âme.
It is described below by way of example and with reference to the figures of the appended drawing, an extender according to the invention and a connector provided with such an extender.
  • Figure 1 shows an exploded view of the extender.
  • Figure 2 shows the extension during its installation in the core of the coaxial cable.
  • Figure 3 shows, in section along III of Figure 2, the particular shape of a nut threaded into the longitudinal slots of the sleeve of the extension.
  • Figure 4 shows the extension in its clamping position.
  • FIG. 5 represents a connector of a coaxial cable, provided with such a core extender.

Dans la figure 1, on voit l'âme 21 d'un câble coaxial et sa paroi intérieure 21 On voit également, en vue éclatée, le prolongateur 1 composé d'une douille 2, d'un écrou 10 et d'une vis de serrage 12.In Figure 1, we see the core 21 of a coaxial cable and its inner wall 21 We also see, in exploded view, the extension 1 composed of a sleeve 2, a nut 10 and a screw tightening 12.

La douille 2 comporte deux extrémités distinctes, une extrémité rigide 8 de diamètre extérieur 3 munie d'un alésage interne 3' et d'un alésage de plus grand diamètre 7, une extrémité flexible 4 munie de quatre ailettes 5 séparées par quatre fentes longitudinales 6, mieux visibles en figure 3. Ces ailettes 5 s'inscrivent extérieurement dans un cylindre 9 raccordé au diamètre extérieur 3 de l'extrémité rigide 8 par un cône 9'. L'écrou 10, mieux visible en figure 3, comportent quatre arêtes 11.The sleeve 2 has two separate ends, a rigid end 8 with an outside diameter 3 provided with an internal bore 3 'and a bore with a larger diameter 7, a flexible end 4 provided with four fins 5 separated by four longitudinal slots 6 , better visible in Figure 3. These fins 5 are externally in a cylinder 9 connected to the outer diameter 3 of the rigid end 8 by a cone 9 '. The nut 10, better visible in FIG. 3, has four edges 11.

La vis de traction 12 comporte une tête de serrage 15 hexagonale, une partie filetée 14, une extrémité cylindrique 13 et une extrémité de reprise 16 composée de deux épaulements cylindriques 17,18.The traction screw 12 comprises a hexagonal clamping head 15, a threaded part 14, a cylindrical end 13 and a recovery end 16 composed of two cylindrical shoulders 17,18.

Dans la figure 2, montrant la mise en place du prolongateur dans l'âme du câble, on voit que la partie rigide 8 de la douille 2 est introduite à l'intérieur de l'âme 21, jusqu'au niveau du cône 9, et que l'écrou 10 préalablement vissé sur l'extrémité de la partie filetée 14 de la vis de traction 12, est introduit dans les fentes 6 de la douille jusqu'à ce que celui-ci vienne en butée sur la partie rigide 8.In FIG. 2, showing the positioning of the extender in the core of the cable, it can be seen that the rigid part 8 of the sleeve 2 is introduced inside the core 21, up to the level of the cone 9, and that the nut 10 previously screwed onto the end of the threaded part 14 of the traction screw 12 is introduced into the slots 6 of the sleeve until the latter comes into abutment on the rigid part 8.

Dans la figure 3 en coupe suivant III de la figure 2, on voit que les quatre arêtes 11 de l'écrou 10 sont introduites dans les fentes longitudinales 6 de la douille 2.In FIG. 3 in section along III in FIG. 2, it can be seen that the four edges 11 of the nut 10 are introduced into the longitudinal slots 6 of the sleeve 2.

Dans la figure 4, montrant le prolongateur prêt à être serré dans l'âme 20 d'un câble, on voit que la douille 2 est introduite entièrement dans l'âme et que les ailettes 5, sous l'action du cône 9' sont déformées et diminuent la largeur des fentes 6.In FIG. 4, showing the extender ready to be tightened in the core 20 of a cable, it can be seen that the sleeve 2 is inserted entirely in the core and that the fins 5, under the action of the cone 9 'are deformed and reduce the width of the slots 6.

La mise en place du prolongateur dans l'âme du câble s'effectue donc de la manière suivante:The installation of the extension in the core of the cable is therefore carried out as follows:

L'écrou 10 est vissé sur l'extrémité filetée 14 de la vis de traction 12 puis introduit dans la douille, l'ensemble douille-écrou-vis de traction est alors introduit dans l'âme jusqu'au niveau du cône 9' de la douille, puis par pincement de celles-ci jusqu'à l'extrémité des ailettes 5. Il suffit alors de visser la vis de traction et dès que celle-ci est en butée sur l'âme 21, l'écrou glisse dans les fentes resserrées 6 et serre la douille 2 sur la paroi 21' de l'âme 21 par écartement des ailettes 5.The nut 10 is screwed onto the threaded end 14 of the traction screw 12 and then introduced into the socket, the socket-nut-traction screw assembly is then introduced into the core up to the level of the cone 9 'of the bushing, then by pinching them to the end of the fins 5. It is then sufficient to screw the traction screw and as soon as the latter is in abutment on the core 21, the nut slides in the tightened slots 6 and tightens the sleeve 2 on the wall 21 ′ of the core 21 by spacing the fins 5.

Dans la figure 5, montrant le prolongateur mis en place dans un connecteur, on voit ce prolongateur composé de la douille 2, de l'écrou 10 et d'une vis de traction 12 munie d'une extrémité de reprise composée de deux épaulements cylindriques 17, 18. Ce prolongateur est engagé dans l'âme 21 d'un câble coaxial 20 qui comprend également une couche isolante 22 entourant l'âme 21, puis un conducteur extérieur ondulé 23 re- couvert par une couche externe 24.In Figure 5, showing the extension set up in a connector, we see this extension composed of the sleeve 2, the nut 10 and a traction screw 12 provided with a recovery end composed of two cylindrical shoulders 17, 18. This extension is engaged in the core 21 of a coaxial cable 20 which also includes an insulating layer 22 surrounding the core 21, then an undulating external conductor 23 covered by an external layer 24.

Ce connecteur 30 comprend une douille principale 31 recouvrant l'extrémité de la couche externe 24 du câble 20, une autre douille 34 vissée sur la douille 31 et prenant appui sur la couche isolante 22 du câble, un écrou 40 immobilisé en translation par un jonc 60 monté à demeure dans une gorge 37 de la douille 34, une pièce fendue 43 vissée dans la douille 34 et comportant des ailettes 43', un tube 50 emmanché sur l'épaulement 18 de la vis de traction et comportant un embout 52.This connector 30 comprises a main socket 31 covering the end of the external layer 24 of the cable 20, another socket 34 screwed onto the socket 31 and bearing on the insulating layer 22 of the cable, a nut 40 immobilized in translation by a rod 60 permanently mounted in a groove 37 of the socket 34, a split piece 43 screwed into the socket 34 and comprising fins 43 ′, a tube 50 fitted on the shoulder 18 of the traction screw and comprising a nozzle 52.

Un joint torique 62 est placé entre le conducteur extérieur 23 et la douille 31, et un autre joint torique 33 assure l'étanchéité entre les douilles 31 et 34. Un jonc métallique 65 plaque l'extrémité du conducteur extérieur 23 sur un cône 36 de la douille 34 serrée par l'intermédiaire d'une clé engagée dans les crans 35.An O-ring 62 is placed between the outer conductor 23 and the socket 31, and another O-ring 33 seals between the sockets 31 and 34. A metal rod 65 plates the end of the outer conductor 23 on a cone 36 of the socket 34 tightened by means of a key engaged in the notches 35.

Une rondelle 61 entoure la tête de serrage 15, et une couche isolante 44, par exemple en polytétra- fluoréthylène ou polythène, recouvre l'épaulement 17 de la vis de traction et le tube 50 jusqu'au niveau de son embout 52.A washer 61 surrounds the clamping head 15, and an insulating layer 44, for example made of polytetrafluoroethylene or polythene, covers the shoulder 17 of the traction screw and the tube 50 up to its end 52.

L'embout 52 et les ailettes 43' s'engagent dans une douille de connection normalisée (et non représentée), tandis que l'écrou 40 est vissé sur cette douille. L'étanchéité entre le connecteur 30 et cette douille est assurée par un joint 42 placé dans une gorge 38 de la douille 34.The end piece 52 and the fins 43 ′ engage in a standardized connection socket (and not shown), while the nut 40 is screwed onto this socket. The seal between the connector 30 and this socket is ensured by a seal 42 placed in a groove 38 of the socket 34.

Sans sortir du cadre de l'invention, ce prolongateur peut être utilisé dans tous types de connecteurs de câbles coaxiaux ou servir au raccordement des âmes de deux câbles coaxiaux, en transformant l'extrémité de reprise de la vis de traction en une tige filetée équivalente à la partie filetée de la vis mais de pas inverse, et en ajoutant un autre écrou et une autre douille dans l'âme du deuxième câble.Without departing from the scope of the invention, this extender can be used in all types of coaxial cable connectors or serve to connect the cores of two coaxial cables, by transforming the recovery end of the traction screw into an equivalent threaded rod to the threaded part of the screw but of reverse pitch, and by adding another nut and another socket in the core of the second cable.
