Description

La présente invention concerne le domaine des câbles de transmission de puissance ou de signaux de données, tels que des câbles électriques et optiques, et plus particulièrement les câbles destinés à être enterrés.The present invention relates to the field of power transmission cables or data signals, such as electrical and optical cables, and more particularly the cables intended to be buried.

ETAT DE LA TECHNIQUESTATE OF THE ART

Généralement, un câble comprend une âme conductrice destinée à transporter de l'électricité ou de la lumière (âme en cuivre ou aluminium, ou fibre optique par exemple) entourée d'un isolant et d'une gaine protégeant le câble des contraintes mécaniques auquel celui-ci est exposé lors de son installation (abrasion, objets tranchants en fond de tranchée). Cette gaine est parfois entourée d'une couche externe destinée à renforcer la protection mécanique du câble lors de sa pose dans des milieux dont la granulométrie est forte, permettant ainsi d'éviter d'avoir à poser le câble sur lit de sable et autorisant donc la réalisation des tranchées moins profondes. Lorsque le câble doit être raccordé à une installation ou lors de sa remontée le long d'un poteau, il est nécessaire de procéder au retrait de cette couche externe sur une longueur pouvant s'élever à une dizaine de mètres. Cette opération a généralement lieu à l'aide d'une pince dénude-câble dans laquelle on place le câble. La pince est équipée d'une lame dont l'enfoncement dans la couche externe est réglé manuellement pour correspondre à l'épaisseur de celle-ci. La pince est ensuite déplacée sur la longueur de câble à dénuder réalisant une fente longitudinale dont les flancs sont séparés afin de retirer la couche externe. Le réglage manuel de la profondeur d'enfoncement de la lame est à l'origine de nombreux problèmes car un enfoncement insuffisant oblige l'opérateur à exercer une force importante pour écarter les bords de la fente découpée tandis qu'un enfoncement trop important endommage la gaine de protection.Generally, a cable comprises a conductive core intended to carry electricity or light (copper or aluminum core, or optical fiber for example) surrounded by an insulator and a sheath protecting the cable from mechanical stresses to which the it is exposed during its installation (abrasion, sharp objects in trench bottom). This sheath is sometimes surrounded by an outer layer intended to reinforce the mechanical protection of the cable when it is laid in media with a large grain size, thus avoiding the need to lay the cable on a sand bed and thus allowing making the trenches shallower. When the cable is to be connected to an installation or when it goes up along a pole, it is necessary to remove this outer layer over a length of up to ten meters. This operation usually takes place using a cable stripper in which the cable is placed. The clamp is equipped with a blade whose depression in the outer layer is manually adjusted to match the thickness thereof. The gripper is then moved along the length of the stripping cable forming a longitudinal slot whose flanks are separated in order to remove the outer layer. Manual adjustment of the depth of insertion of the blade is at the root of many problems because an insufficient depression forces the operator to exert a strong force to spread the edges of the cut slot while a depression too important damages the protective shealth.

Enfin, il est également connu de la demande de brevet FR2831703 des couches externes comprenant des reliefs présentant généralement un pas d'hélice résultant du mode de fabrication. Cette configuration contraint l'opérateur à faire tourner la pince dénude-câble autour de la couche externe au fur et à mesure de son déplacement longitudinal compliquant encore la manoeuvre de découpe et de dépose de la couche externe.Finally, it is also known from the patent application FR2831703 outer layers comprising reliefs generally having a helical pitch resulting from the method of manufacture. This configuration forces the operator to rotate the cable stripper around the outer layer as its longitudinal movement further complicating the cutting operation and removal of the outer layer.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Un but de l'invention est de faciliter les opérations de retrait d'une couche externe d'un câble tout en préservant l'intégrité de la gaine de protection.An object of the invention is to facilitate the operations of removing an outer layer of a cable while preserving the integrity of the protective sheath.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

A cet effet, on prévoit un câble comportant au moins une âme conductrice s'étendant dans une gaine recouverte d'une couche externe cannelée comportant des reliefs longitudinaux séparés les uns des autres par des cannelures. Selon l'invention, au moins un des reliefs longitudinaux est de plus forte largeur que les autres reliefs et la couche externe comporte, en regard de chaque cannelure jouxtant le relief de plus forte largeur, une zone longitudinale ayant une épaisseur inférieure à une épaisseur de la couche externe en regard des autres cannelures.For this purpose, a cable is provided comprising at least one conductive core extending in a sheath covered with a corrugated outer layer comprising longitudinal protrusions separated from each other by splines. According to the invention, at least one of the longitudinal reliefs is of greater width than the other reliefs and the outer layer has, opposite each groove adjoining the relief of greater width, a longitudinal zone having a thickness less than a thickness of the outer layer facing the other flutes.

Ainsi, lorsque l'on souhaite dénuder une portion d'un tel câble, il suffit de saisir, par exemple à l'aide d'une pince, le relief de plus forte épaisseur qui permet une bonne prise, et d'exercer une traction selon une direction sensiblement radiale. Les portions de plus faible épaisseur entourant le relief de plus forte largeur se déchirent et permettent ainsi de réaliser une ouverture large dans la couche externe sans utiliser d'outil coupant susceptible d'endommager la gaine de protection du câble ou de blesser un utilisateur.Thus, when it is desired to strip a portion of such a cable, it suffices to grasp, for example using a clip, the thicker relief that allows a good grip, and to exert traction in a substantially radial direction. The smaller thickness portions surrounding the larger width relief tear and thus allow for a wide opening in the outer layer without using a cutting tool that could damage the protective sheath of the cable or injure a user.

Selon une version avantageuse de l'invention, le relief de plus forte largeur possède au moins un flanc bombé.According to an advantageous version of the invention, the higher width relief has at least one bulging flank.

Ainsi, le flanc s'étend partiellement au dessus de la zone longitudinale de plus faible épaisseur de la cannelure et protège celle-ci des sollicitations mécaniques telles que le poinçonnement ou l'abrasion. Cette protection contre le poinçonnement peut également être renforcée lorsque le relief de plus forte largeur est séparé des reliefs adjacents d'une distance inférieure à une distance séparant les autres reliefs les uns des autres.Thus, the flank extends partially above the longitudinal region of smaller thickness of the groove and protects it from mechanical stresses such as punching or abrasion. This protection against punching can also be enhanced when the relief of greater width is separated from the adjacent reliefs by a distance less than a distance separating the other reliefs from each other.

D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention.Other features and advantages of the invention will become apparent on reading the following description of a particular non-limiting embodiment of the invention.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

En référence aux figures 1 et 2, le câble électrique généralement désigné 1 comporte, de façon connue en soi, une âme conductrice 2, en métal tel que le cuivre ou l'aluminium, qui s'étend selon un axe longitudinal X et qui est recouverte d'une couche conductrice 3, elle-même recouverte d'une couche isolante 4. La couche isolante 4 est à son tour recouverte d'une couche conductrice 5 sur laquelle est disposé un blindage métallique 6 recouvert d'une gaine de protection 7, cette dernière étant généralement en polyéthylène ou en polychlorure de vinyle.With reference to figures 1 and 2 , the generally designated electric cable 1 comprises, in a manner known per se, a conductive core 2, made of metal such as copper or aluminum, which extends along a longitudinal axis X and which is covered with a conductive layer 3 it is itself covered with an insulating layer 4. The insulating layer 4 is in turn covered with a conductive layer 5 on which is disposed a metal shield 6 covered with a protective sheath 7, the latter being generally made of polyethylene or polychloride vinyl.

Le câble comporte en outre une couche externe 8 qui recouvre la gaine de protection 7 et comprend des cannelures 9 séparant des reliefs longitudinaux, ici des créneaux 10 de même hauteur, c'est-à-dire dont les surfaces les plus éloignées de l'axe longitudinal X appartiennent à une même surface cylindrique d'axe X.The cable further comprises an outer layer 8 which covers the protective sheath 7 and comprises grooves 9 separating longitudinal reliefs, here crenellations 10 of the same height, that is to say the surfaces farthest from the longitudinal axis X belong to the same cylindrical surface of axis X.

Selon l'invention, la couche externe 8 comprend un relief de largeur plus importante que les créneaux 10, ici un pavé de marquage 11 destiné à recevoir un marquage identifiant le câble, sa composition et/ou le type de conducteur(s) qu'il contient. Ce pavé de marquage 11 a une hauteur identique à la hauteur des créneaux 10. Les portions de la couche externe 8 en regard des cannelures 12 et 13 jouxtant le pavé de marquage 11 sont d'épaisseur plus faible que l'épaisseur de la couche externe 8 en regard des cannelures 9. Le pavé de marquage 11 possède, ici, deux flancs bombés 14 et 15 qui, en surplombant partiellement les cannelures 12 et 13, protègent celles-ci des impacts et par exemple du poinçonnement. Un autre mode de protection contre le poinçonnement des cannelures 12 et 13 consiste à agencer le pavé de marquage 11 de manière à ce que les créneaux 10 adjacents soient séparés de celui-ci par une distance inférieure à la distance séparant les autres reliefs les uns des autres.According to the invention, the outer layer 8 comprises a relief of greater width than the crenellations 10, here a marking block 11 intended to receive a marking identifying the cable, its composition and / or the type of conductor (s) that it contains. This marking block 11 has a height identical to the height of the crenellations 10. The portions of the outer layer 8 facing the flutes 12 and 13 adjacent to the marking pad 11 are of a thickness smaller than the thickness of the outer layer 8 opposite the flutings 9. The marking pad 11 has, here, two curved flanks 14 and 15 which, partially overlying the flutes 12 and 13, protect them from impacts and for example punching. Another way of protecting the grooves 12 and 13 against punching is to arrange the marking block 11 so that the adjacent slots 10 are separated from the latter by a distance less than the distance separating the other reliefs from each other. other.

Avantageusement, la couche externe 8 est réalisée en une matière présentant une élasticité plus élevée que la gaine de protection 7 et dont l'adhérence à la gaine de protection 7 est inférieure à la résistance au déchirement de la couche externe 8. La couche externe 8 est par exemple réalisée en élastomère réticulé, ou en matière thermoplastique élastomère c'est-à-dire un polymère multiphasique comportant une phase thermoplastique et une phase polymère mélangées, le polymère obtenu pouvant être soit sous forme massique soit sous forme cellulaire, et n'adhérant pas naturellement à la gaine de protection 7. Ainsi la couche externe 8 assure, par son élasticité, un amortissement des contraintes auquel est soumis le câble 1, l'adhérence limitée de la couche externe 8 sur la gaine de protection 7 facilite également sa dépose.Advantageously, the outer layer 8 is made of a material having a higher elasticity than the protective sheath 7 and whose adhesion to the protective sheath 7 is lower than the tear resistance of the outer layer 8. The outer layer 8 is for example made of crosslinked elastomer, or thermoplastic elastomer material that is to say a multiphasic polymer comprising a thermoplastic phase and a mixed polymer phase, the polymer obtained can be either in bulk or cellular form, and not naturally adhering to the protective sheath 7. Thus, the outer layer 8 provides, by its elasticity, a stress damping to which the cable 1 is subjected, the limited adhesion of the outer layer 8 to the protective sheath 7 facilitates also his removal.

Selon un mode particulier de réalisation détaillé en figure 1, les créneaux 10 et le pavé de marquage 11 s'étendent en hélice autour de la gaine, procurant une protection multidirectionnelle au câble et facilitant la flexion du câble 8 lors des opérations de pose et d'enroulage.According to a particular embodiment detailed in figure 1 the slots 10 and the marking pad 11 extend helically around the sheath, providing multidirectional protection to the cable and facilitating bending of the cable 8 during laying and winding operations.

En référence aux figures 1 à 3, la couche externe 8 comporte des fibres de renforts 16, par exemple des fibres en aramide, s'étendant selon une direction sensiblement longitudinale du câble 1, à l'aplomb des cannelures 9. Ces fibres permettent de reprendre les efforts de tirage exercés sur le câble et de répartir les effets d'un choc radial ponctuel sur l'ensemble du câble ce qui réduit grandement le risque d'endommagement de celui-ci.With reference to Figures 1 to 3 , the outer layer 8 comprises reinforcing fibers 16, for example aramid fibers extending in a substantially longitudinal direction of the cable 1, in line with the grooves 9. These fibers allow to resume the drawing forces exerted on the cable and distribute the effects of a radial shock point on the entire cable which greatly reduces the risk of damage to it.

En référence à la figure 3, lorsqu'il souhaite déposer la couche externe 8 du câble 1, un opérateur saisit, à l'aide d'une pince, le relief 11 en une extrémité libre du câble 1 et exerce sur celui-ci une traction dans une direction sensiblement radiale. Les sous-épaisseurs en regard des cannelures 12 et 13 situées de part et d'autre du relief 11 cèdent sous l'effort exercé et se déchirent, ouvrant ainsi la couche externe 8 afin d'en permettre la dépose. On obtient ainsi un câble 1 comprenant une couche externe 8 qui assure une protection aux chocs et aux agressions mécaniques, autorisant alors sa pose dans une tranchée sans nécessiter la mise en oeuvre d'un matériau à texture fine. Le retrait de cette couche externe 8 se fait aisément, sans outil spécifique et garantit l'intégrité de la gaine de protection 7. L'absence d'utilisation d'outil coupant pour les opérations de retrait de la couche externe 8 permet également de réduire les risques de blessures des opérateurs par coupure.With reference to the figure 3 when it wishes to deposit the outer layer 8 of the cable 1, an operator grasps the relief 11 at a free end of the cable 1 with a pincer and exerts on the latter a traction in a substantially radial direction . The under-thickness facing the grooves 12 and 13 located on either side of the relief 11 yield under the force exerted and tear, thus opening the outer layer 8 to allow removal. A cable 1 is thus obtained comprising an outer layer 8 which provides protection against shocks and mechanical aggression, thereby allowing it to be laid in a trench without requiring the use of a fine-textured material. The removal of this outer layer 8 is easy, without specific tools and guarantees the integrity of the protective sheath 7. The absence of use of cutting tool for the withdrawal operations the outer layer 8 also reduces the risk of injury to operators by cutting.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit mais englobe toute variante entrant dans le champ de l'invention telle que définie par les revendications.Of course, the invention is not limited to the embodiment described but encompasses any variant within the scope of the invention as defined by the claims.
