Description

L'invention se rapporte à un câble électrique doté d'un moyen de dissuasion de vol. La partie conductrice des câbles électriques, qui est constituée par un arrangement de plusieurs brins métalliques, pouvant par exemple être composés de cuivre, est particulièrement recherchée par les voleurs, car elle s'écoule très bien à la revente, à cause de son prix élevé. Le cadre de l'invention est de proposer des câbles électriques, non pas dotés d'un moyen de dissuasion de vol actif, qui pourrait empêcher physiquement un voleur de dérober sur le terrain lesdits câbles, mais de proposer un moyen de dissuasion, qui permettrait à des câbles volés de pouvoir être identifiés, et qui permettrait donc à un acheteur de détecter une origine frauduleuse desdits câbles.The invention relates to an electric cable with a deterrent theft. The conductive part of the electric cables, which is constituted by an arrangement of several metal strands, which may for example be composed of copper, is particularly sought after by thieves, because it flows very well on resale, because of its high price. . The scope of the invention is to propose electrical cables, not equipped with an active flight deterrent device, which could physically prevent a thief from stealing the cables from the ground, but to propose a deterrent, which would allow stolen cables to be identified, and that would allow a buyer to detect a fraudulent origin of said cables.

Des câbles dotés de moyens de dissuasion de vol existent, et ont déjà fait l'objet de brevets. On peut, par exemple, citer le brevet US2010/0264206 , qui se rapporte à des câbles dont les brins de cuivre ont subi sur leur surface un marquage par gravure laser. De cette manière, lesdits câbles se retrouvent directement marqués par l'intermédiaire de traces en relief, laissées au niveau de leur surface, et pouvant représenter indifféremment un code alphanumérique, ou une série de chiffres ou une série de lettres. Cette technique demeure peu efficace vis-à-vis d'agressions malveillantes, comme par exemple un brûlage intentionnel par les voleurs, car les résidus se déposeraient sur les traces peu profondes du marquage, et rendraient ce marquage illisible. De plus, les empreintes réalisées dans le cadre de ce marquage sont assez complexes, dans la mesure où elles représentent chacune un chiffre, une lettre ou tout autre signe cabalistique.Cables with flight deterrents exist, and have already been patented. One can, for example, quote the patent US2010 / 0264206 , which refers to cables whose copper strands have undergone laser etching marking on their surface. In this way, said cables are found directly marked by means of relief traces, left at their surface, and can represent indifferently an alphanumeric code, or a series of numbers or a series of letters. This technique is not very effective against malicious attacks, such as an intentional burning by thieves, because the residues would be deposited in shallow traces of marking, and make the mark illegible. In addition, the prints made as part of this marking are quite complex, in that they each represent a figure, a letter or any other cabalistic sign.

Le document DE409794 décrit un câble selon le préambule de la revendication 1.The document DE409794 discloses a cable according to the preamble of claim 1.

D'autres techniques de marquage ont déjà été utilisées, comme le dépôt d'une encre ou d'un matériau de marquage sur la surface du câble ou d'une gaine isolante, mais les marques ainsi produites, ne résistent pas à un brûlage des câbles, et s'effacent sans laisser de traces, rendant impossible toute identification du câble.Other marking techniques have already been used, such as the deposition of an ink or marking material on the surface of the cable or an insulating sheath, but the marks thus produced do not resist burning. cables, and disappear without leaving any traces, making it impossible to identify the cable.

Les câbles électriques selon l'invention, possèdent des moyens de dissuasion de vol, fondés sur un marquage inaltérable pouvant résister à tout type d'agression, comme par exemple un brûlage, ledit marquage ayant la particularité d'être assimilable à un code-barres en relief. De cette manière, les empreintes en relief constituant ce marquage, ont une géométrie simple et à peu près répétitive, et sont donc rapides à mettre en oeuvre, au moyen d'un outillage largement éprouvé, et donc bien maîtrisé. En effet, un code-barres en relief peut, par exemple, être constitué d'une série de traits plus ou moins en relief, ou d'une série de perforations plus ou moins importantes, et ne nécessite donc pas que chaque empreinte le constituant ait un motif compliqué de type chiffre ou lettre.The electric cables according to the invention have a flight deterrent, based on an unalterable marking that can withstand any type of aggression, such as a burning, said marking having the distinction of being comparable to a bar code embossed. In this way, the raised imprints constituting this marking, have a simple and almost repetitive geometry, and are therefore quick to implement, by means of tools that are widely tested and therefore well controlled. Indeed, a raised bar code may, for example, consist of a series of more or less raised lines, or a series of more or less important perforations, and therefore does not require that each imprint constituting it has a complicated figure or letter pattern.

L'invention a pour objet un câble électrique comprenant au moins deux brins conducteurs et des moyens de dissuasion de vol sous la forme d'un marquage. La principale caractéristique d'un câble selon l'invention, est que le marquage consiste en une série d'empreintes en relief assimilable à un code-barres. Le fait que le marquage soit assimilable à un code-barres, signifie que chaque empreinte laissée ne doit pas obligatoirement représenter un signe distinctif et/ou figuratif en elle-même, mais doit être incluse avec les autres empreintes, afin que l'ensemble de ces empreintes constitue une signature distinctive du câble. Elles peuvent donc n'avoir qu'une configuration simple et facilement reproductible, comme par exemple un trait ou un cercle, lesdites empreintes pouvant être réalisées rapidement les unes à la suite des autres, au moyen d'une technique simple et largement éprouvée. De plus, puisque le marquage peut par exemple être réalisé au moyen d'un outillage mécanique, les empreintes laissées peuvent avoir une profondeur ou une hauteur importante, accentuant leur caractère d'inaltérabilité et rendant difficile leur effacement. Une empreinte en relief peut consister en un creux, un évidement, ou un trou. Mais elle peut également se traduire par une protubérance saillante. Le marquage peut indifféremment être réalisé sur au moins un brin métallique du câble, ou sur toute autre partie dudit câble, existante ou rapportée. Le terme « câble » est général, et peut désigner par exemple, aussi bien un simple assemblage de brins conducteurs sans agencement particulier, qu'un arrangement de brins conducteurs dans une structure dotée d'éléments isolants et respectant une certaine géométrie.The subject of the invention is an electrical cable comprising at least two conductive strands and means of deterring theft in the form of a marking. The main characteristic of a cable according to the invention is that the marking consists of a series of embossed prints similar to a barcode. The fact that the marking is similar to a barcode means that each impression left must not necessarily represent a distinctive and / or figurative sign in itself, but must be included with the other prints, so that the whole these fingerprints constitute a distinctive signature of the cable. They can therefore have only a simple and easily reproducible configuration, such as a line or a circle, said fingerprints can be made quickly one after another, using a simple and widely proven technique. In addition, since the marking may for example be achieved by means of mechanical tools, the impressions left may have a depth or a large height, accentuating their character of inalterability and making it difficult to erase them. A relief imprint can consist of a recess, a recess, or a hole. But it can also result in a prominent protuberance. The marking can indifferently be carried out on at least one metal strand of the cable, or on any other part of said cable, existing or reported. The term "cable" is general, and may designate, for example, a simple assembly of conductive strands without a particular arrangement, an arrangement of conductive strands in a structure with insulating elements and respecting a certain geometry.

Avantageusement, la série d'empreintes est répétitive sur toute la longueur du câble. De cette manière, le marquage est étalé et ne peut donc pas être retiré ou effacé par un voleur potentiel, au moyen d'une opération simple et rapide.Advantageously, the series of impressions is repetitive over the entire length of the cable. In this way, the marking is spread and can not be removed or erased by a potential thief by means of a simple and fast operation.

Selon un premier mode de réalisation préféré d'un câble selon l'invention, le câble comprend une pluralité de brins métalliques, le marquage étant réalisé sur au moins l'un desdits brins. Dans le cas d'un arrangement de brins conducteurs présentant un brin central, le marquage est préférentiellement réalisé sur le brin central, afin qu'il se retrouve peu accessible par un voleur ayant la volonté de l'effacer ou de le modifier. De façon avantageuse, le brin central est marqué par crantage, le marquage résultant étant constitué par une série de crans successifs le long du brin.According to a first preferred embodiment of a cable according to the invention, the cable comprises a plurality of metal strands, the marking being formed on at least one of said strands. In the case of an arrangement of conductive strands having a central strand, the marking is preferably carried out on the central strand, so that it is not very accessible by a thief having the will to erase or modify it. Advantageously, the central strand is marked by notching, the resulting marking being constituted by a series of successive notches along the strand.

Selon l'invention, le marquage est réalisé dans une pièce rapportée, solidarisée au câble. De cette manière, la pièce rapportée sert de support de marquage et évite ainsi aux brins d'avoir à être marqués directement, de manière à préserver leur intégrité structurelle. Le terme « rapportée » appliqué à la pièce, signifie que cette pièce est spécialement dédiée au support d'un marquage, et qu'elle n'a pas d'autres fonctions au sein du câble.According to the invention, the marking is made in an insert, secured to the cable. In this way, the insert serves as a marking medium and thus prevents the strands from having to be marked directly, so as to preserve their structural integrity. The term "reported" applied to the part means that this part is specifically dedicated to the support of a marking, and that it has no other functions within the cable.

Avantageusement, la pièce rapportée s'étend sur toute la longueur du câble, afin d'éviter d'avoir des zones du câble non marquées, et susceptibles d'être découpées frauduleusement afin d'être revendues. Selon un autre mode de réalisation préféré d'un câble selon l'invention, la pièce rapportée est un écran entourant au moins partiellement ledit câble. En plus de servir de support de marquage pour identifier le câble, la pièce peut ainsi assurer une fonction de protection dudit câble.Advantageously, the insert extends over the entire length of the cable, to avoid having unmarked cable areas, and may be cut fraudulently to be resold. According to another preferred embodiment of a cable according to the invention, the insert is a screen at least partially surrounding said cable. In addition to serving as marking support for identifying the cable, the part can thus provide a protection function of said cable.

Selon l'invention, la pièce rapportée est intimement mêlée aux brins de façon désordonnée, pour empêcher son extraction dudit câble. En effet, le risque de réaliser un marquage sur une pièce rapportée, est de pouvoir retirer simplement et rapidement ladite pièce rapportée afin de ne pas pouvoir identifier l'origine du câble. Le fait de placer cette pièce dans le câble, sans ordonnancement particulier, et de manière à sinuer de façon anarchique entre les brins conducteurs du câble, la rend inviolable.According to the invention, the insert is intimately mixed with the strands in a disordered manner, to prevent its extraction of said cable. Indeed, the risk of making a marking on a patch, is to simply remove and quickly said insert so as not to be able to identify the origin of the cable. The fact of placing this piece in the cable, without particular scheduling, and in order to sin disordered between the conductive strands of the cable, makes it inviolable.

De façon préférentielle, la ligne comprend plusieurs brins périphériques entourant un brin central, la pièce rapportée étant insérée entre le brin central et au moins un brin périphérique. Il est en effet important que la pièce marquée soit « enfouie » dans le câble électrique, afin qu'elle ne puisse pas être facilement accessible de l'extérieur, pour être ensuite retirée, coupée ou arrachée de façon malveillante.Preferably, the line comprises a plurality of peripheral strands surrounding a central strand, the insert being inserted between the central strand and at least one peripheral strand. It is indeed important that the marked part is "buried" in the electric cable, so that it can not be easily accessible from the outside, then to be removed, cut or torn off maliciously.

Selon un premier mode de réalisation préféré d'un câble électrique selon l'invention, la pièce rapportée est insérée entre le brin central et tous les brins périphériques. De cette manière, chaque pièce est étroitement mélangée aux brins, rendant son accessibilité encore plus difficile.According to a first preferred embodiment of an electric cable according to the invention, the insert is inserted between the central strand and all the peripheral strands. In this way, each piece is closely mixed with the strands, making its accessibility even more difficult.

Selon un autre mode de réalisation préféré d'un câble électrique selon l'invention, la pièce rapportée entoure complètement le brin central. Il s'agit d'une configuration simplifiée, permettant à la pièce ajoutée d'avoir une géométrie cylindrique, et d'être assimilable à une gaine pour le brin central, pouvant enserrer, de façon étroite ou plus lâche, ledit brin central.According to another preferred embodiment of an electric cable according to the invention, the insert completely surrounds the central strand. This is a simplified configuration, allowing the added part to have a cylindrical geometry, and to be comparable to a sheath for the central strand, which can grip, narrowly or loosely, said central strand.

Préférentiellement, la pièce est un feuillard métallique de faible épaisseur. En effet, la pièce ajoutée ne doit pas être encombrante, et doit pouvoir s'immiscer dans le câble, sans provoquer de modification dommageable à ses propriétés électriques. Un feuillard est par définition une pièce très fine, et répond à cette exigence de faible encombrement. De plus, une pièce métallique est solide, et résiste facilement à des contraintes mécaniques ou thermiques. De cette manière, elle ne se dégrade pas dans le temps.Preferably, the piece is a thin metal strip. Indeed, the added part must not be bulky, and must be able to interfere in the cable, without causing a damaging change to its electrical properties. A strip is by definition a very fine piece, and meets this requirement of small size. In addition, a metal part is solid, and easily withstands mechanical or thermal stresses. In this way, it does not deteriorate in time.

Selon un autre mode de réalisation préféré d'un câble électrique selon l'invention, le feuillard est en cuivre.According to another preferred embodiment of an electric cable according to the invention, the strip is made of copper.

Avantageusement, le marquage consiste en une série de perforations réalisées dans la pièce rapportée. Il s'agit d'un marquage simple, rapide à mettre en oeuvre et bien maîtrisé. Ces perforations peuvent être obtenues par différentes techniques, comme le poinçonnage ou le crantage. Ces perforations ont des formes simples et peuvent, par exemple, être représentées par une fente, un trou circulaire ou ovale.Advantageously, the marking consists of a series of perforations made in the insert. It is a simple marking, quick to implement and well controlled. These perforations can be obtained by different techniques, such as punching or notching. These perforations have simple shapes and can, for example, be represented by a slot, a circular or oval hole.

De façon préférentielle, une série de perforations comporte plusieurs perforations alignées selon une direction longitudinale dudit câble. De cette manière, le marquage pourra être effectif sur une zone importante de la ligne électrique, permettant de multiplier le nombre de perforations et de rendre le marquage très spécifique du câble ou de la ligne auquel il se rapporte.Preferably, a series of perforations comprises several perforations aligned in a longitudinal direction of said cable. In this way, the marking can be effective over a large area of the power line, to multiply the number of perforations and make the very specific marking of the cable or the line to which it relates.

Préférentiellement, les perforations sont de tailles et de formes différentes. Cette diversité des perforations accroît encore les combinaisons de marquage.Preferably, the perforations are of different sizes and shapes. This diversity of perforations further increases the marking combinations.

De façon avantageuse, le feuillard est une bande comprenant des encoches supplémentaires sur au moins l'un de ses bords. Il s'agit d'un marquage supplémentaire, facile à réaliser.Advantageously, the strip is a strip comprising additional notches on at least one of its edges. It is an additional marking, easy to achieve.

L'invention a également pour objet un procédé de fabrication d'un câble électrique conforme à l'invention, dont la principale caractéristique est que les empreintes sont réalisées au moyen d'une technique à choisir parmi le poinçonnage mécanique, le crantage mécanique, le rayonnement laser et le jet d'eau sous pression.The subject of the invention is also a method for manufacturing an electric cable according to the invention, the main characteristic of which is that the impressions are made by means of a technique to be chosen from mechanical punching, mechanical notching, laser radiation and the jet of water under pressure.

Les câbles électriques selon l'invention présentent l'avantage de posséder un moyen de dissuasion sous la forme d'un code-barres en relief, pouvant être facilement et rapidement réalisé au moyen d'un outillage bien maîtrisé. L'avantage d'un code-barres en relief, est que chaque empreinte le constituant n'a pas à posséder une géométrie particulière et complexe, reconnaissable en elle-même, puisque c'est l'ensemble des empreintes qui va constituer la signature du câble. Enfin, les techniques mises en oeuvre pour la réalisation d'un marquage sur les câbles selon l'invention, ont l'avantage de pouvoir réaliser des reliefs de forte amplitude, rendant lisible ledit marquage en toutes circonstances.The electric cables according to the invention have the advantage of having a deterrent means in the form of a bar code in relief, which can be easily and quickly achieved by means of well-controlled tools. The advantage of an embossed barcode is that each imprint on constituent does not have to have a particular geometry and complex, recognizable in itself, since it is the set of footprints that will constitute the signature of the cable. Finally, the techniques used for carrying out marking on the cables according to the invention have the advantage of being able to produce high amplitude reliefs, making said marking legible in all circumstances.

En se référant aux figures 1 et 2, un câble électrique 1,10 selon l'invention comprend un brin conducteur central 2 entouré de sept brins conducteurs périphériques 3, régulièrement espacés autour dudit brin central 2, chaque brin conducteur 2,3 étant réalisé en cuivre. Chaque câble électrique 1,10 comporte un moyen de dissuasion de vol, sous la forme d'une pièce rapportée 6,16 marquée et entremêlée avec les brins conducteurs 2,3. Cette pièce rapportée 6,16 s'étend sur toute la longueur du câble 1,10, et demeure donc intimement liée auxdits brins 2,3.Referring to Figures 1 and 2 , an electric cable 1,10 according to the invention comprises a central conductor wire 2 surrounded by seven peripheral conductive strands 3, regularly spaced around said central strand 2, each conducting strand 2,3 being made of copper. Each electrical cable 1.10 has a flight deterrent in the form of a marked insert 6.16 intermingled with the conducting strands 2, 3. This insert 6.16 extends over the entire length of the cable 1.10, and therefore remains intimately linked to said strands 2, 3.

En se rapportant à la figure 3, la pièce rapportée 6 est constituée par un feuillard 7,17 en cuivre, de faible épaisseur pouvant facilement être inséré entre plusieurs brins conducteurs 2,3 du câble électrique 1,10. Ce feuillard 7,17 présente la particularité d'être marqué au moyen d'une série de perforations 8 pouvant, soit être toutes identiques entre elles, soit posséder des formes et des dimensions différentes. Ces perforations 8 sont préférentiellement alignées entre elles sur le feuillard 7,17 selon un axe longitudinal dudit feuillard 7,17, et donc selon un axe longitudinal du câble 1,10 dans lequel il est incorporé. Le marquage distinctif du câble 1,10 est réalisé au moyen d'une série de perforations 8, ladite série étant répétée de façon identique le long dudit câble 1,10, à des intervalles réguliers. Une série de perforations 8 dans le feuillard 7,17 matérialise ainsi une signature, permettant d'identifier l'origine du câble électrique 1,10. Chaque marquage correspondant à une série particulière de perforations 8, et est donc représentatif d'un seul câble 2,3. De cette manière, un voleur potentiel ayant dérobé un câble électrique 1,10 selon l'invention, aurait des difficultés à l'écouler, puisque un acheteur potentiel pourrait connaitre l'origine de ce câble 2,3, par le biais de ce marquage, et ainsi apprécier le caractère illicite de la revente. Une série de perforations 8 réalisée dans le feuillard 7,17 peut ainsi être assimilée à un code-barres.By referring to the figure 3 , the insert 6 is constituted by a thin copper strip 7,17, which can easily be inserted between several conducting strands 2,3 of the electric cable 1,10. This strip 7,17 has the particularity of being marked by means of a series of perforations 8 that can either be all identical to each other, or have different shapes and dimensions. These perforations 8 are preferably aligned with each other on the strip 7,17 along a longitudinal axis of said strip 7,17, and therefore along a longitudinal axis of the cable 1,10 in which it is incorporated. The distinctive marking of the cable 1.10 is achieved by means of a series of perforations 8, said series being repeated identically along said cable 1.10 at regular intervals. A series of perforations 8 in the strip 7,17 materializes a signature, to identify the origin of the electric cable 1,10. Each marking corresponds to a particular series of perforations 8, and is therefore representative of a single cable 2,3. In this way, a potential thief having stolen an electrical cable 1,10 according to the invention, would have difficulty in selling it, since a potential buyer could know the origin of this cable 2,3, through this marking , and thus appreciate the unlawful nature of the resale. A series of perforations 8 made in the strip 7,17 can thus be likened to a barcode.

En se référant à la figure 1, selon un premier mode de réalisation préféré d'un câble électrique 1, selon l'invention, le feuillard 7 entoure complètement le brin central 2. Il peut alors être assimilé à une gaine métallique pour le brin central 2, soit en enserrant étroitement ledit brin central 2 en demeurant à son contact, soit en étant maintenu à distance de celui-ci en minimisant les zones de contact avec lui.Referring to the figure 1 according to a first preferred embodiment of an electric cable 1, according to the invention, the strip 7 completely surrounds the central strand 2. It can then be likened to a metal sheath for the central strand 2, or by tightly enclosing said central strand 2 by remaining in contact with it, or by being kept at a distance from it by minimizing the areas of contact with it.

En se référant à la figure 2, selon un deuxième mode de réalisation préféré d'un câble électrique 10 selon l'invention, le feuillard 17 peut être entremêlé aléatoirement entre les brins conducteurs 2,3 constituant le câble électrique 1,10, de façon à demeurer « enfoui » dans ledit câble 10, et donc inaccessible pour une personne mal intentionnée désirant retirer ou arracher ce feuillard 17 du câble 10.Referring to the figure 2 according to a second preferred embodiment of an electric cable 10 according to the invention, the strip 17 may be intermixed randomly between the conductive strands 2,3 constituting the electric cable 1,10, so as to remain "buried" in said cable 10, and therefore inaccessible to an ill-intentioned person wishing to remove or tear the strap 17 of the cable 10.

Pour les deux modes de réalisation préférés d'un câble électrique 1,10 selon l'invention et précédemment décrits, il est important de préciser que le feuillard 7,17 doit demeurer intimement « mélangé » aux brins 2,3 du câble électrique 1,10, de manière à rester inextricable, et à dissuader un voleur potentiel de le retirer.For the two preferred embodiments of an electric cable 1,10 according to the invention and previously described, it is important to specify that the strip 7,17 must remain intimately "mixed" with the strands 2,3 of the electric cable 1, 10, so as to remain inextricable, and to deter a potential thief from removing it.

Les câbles électriques 1,10 selon l'invention possèdent ainsi une signature inviolable, permettant d'identifier leur origine, ladite signature demeurant parfaitement efficace vis-à-vis d'actes intentionnels et malveillants de type brûlage, en raison de l'amplitude importante des reliefs pratiqués. L'origine des câbles 2,3 est constituée par un certain nombre d'informations, pouvant inclure la date de fabrication, le lieu de fabrication, le numéro de lot, etc.The electric cables 1.10 according to the invention thus have an inviolable signature, making it possible to identify their origin, said signature remaining perfectly effective with respect to intentional and malicious acts of the burning type, because of the large amplitude. reliefs practiced. The origin of the cables 2,3 is constituted by a certain number of information, which can include the date of manufacture, the place of manufacture, the lot number, etc.
