Description

1. Domaine technique de l'invention1. Technical field of the invention

L'invention concerne une ligne d'alimentation électrique, un réseau d'alimentation électrique comprenant une telle ligne d'alimentation et un procédé de fabrication d'une telle ligne d'alimentation. En particulier, l'invention concerne une ligne d'alimentation électrique destinée à un réseau d'alimentation domestique.The invention relates to a power supply line, a power supply network comprising such a power line and a method of manufacturing such a power line. In particular, the invention relates to a power supply line for a domestic power supply network.

2. Arrière-plan technologique2. Technological background

Les lignes d'alimentation électrique sont généralement formées par des câbles électriques en cuivre cylindriques, c'est-à-dire ayant une section circulaire, chaque câble étant entouré d'une gaine isolante en plastique. Ces câbles sont fréquemment utilisés pour des raisons de coût faible, et de résistance mécanique relativement importante pour une utilisation courante.The power supply lines are generally formed by cylindrical copper electrical cables, that is to say having a circular section, each cable being surrounded by a plastic insulating sheath. These cables are frequently used for reasons of low cost, and relatively high mechanical strength for common use.

Néanmoins, ils présentent plusieurs inconvénients, notamment lors de leur utilisation dans un réseau d'alimentation domestique, par exemple dans un appartement ou une maison. Notamment, le volume occupé par le câble cylindrique engendre des problèmes d'installation, de sécurité et d'esthétique. Par exemple, lors de l'installation des câbles sur des parois telles que des murs, le câble doit être fermement fixé pour éviter tout risque d'arrachage volontaire ou accidentel présentant des risques de sécurité. Les gaines isolantes en plastique peuvent donc être abimées et le cuivre devenir apparent. Ces risques sont accentués au niveau d'installations sur plusieurs parois formant des angles droits, le rayon de courbure du câble entraînant la formation d'un espace vide entre le câble et la paroi amplifiant lesdits risques. Ces inconvénients entraînent des difficultés d'installation de câbles pour former un réseau d'alimentation électrique. Pour résoudre ces problèmes de sécurité, les câbles sont soit solidement fixés, soit installés à l'intérieur des murs ou dans des gouttières, ce qui rend difficile toute modification de l'installation qui nécessiterait de lourds travaux.Nevertheless, they have several disadvantages, especially when used in a home power network, for example in an apartment or a house. In particular, the volume occupied by the cylindrical cable causes problems of installation, safety and aesthetics. For example, when installing cables on walls such as walls, the cable must be securely fastened to prevent any risk of accidental or accidental pulling with security risks. Plastic insulating sleeves can therefore be damaged and the copper becomes apparent. These risks are accentuated at installations on several walls forming right angles, the radius of curvature of the cable resulting in the formation of a gap between the cable and the wall amplifying said risks. These disadvantages lead to difficulties in installing cables to form a power supply network. To solve these security problems, the cables are either firmly fixed, or installed inside the walls or in gutters, which makes difficult any modification of the installation which would require heavy work.

De plus, la forme du câble et la présence de la gaine isolante autour du câble réduisent la vitesse refroidissement du câble, notamment au niveau de l'axe du câble où la matière est compacte.In addition, the shape of the cable and the presence of the insulating sheath around the cable reduce the cooling speed of the cable, especially at the cable axis where the material is compact.

Enfin, l'utilisation de cuivre dans le câble rend celui-ci non-adapté à l'utilisation à proximité de denrées alimentaires (dans un réfrigérateur, à proximité d'un plan de travail, etc.), notamment du fait de l'oxydation du cuivre.Finally, the use of copper in the cable makes it unsuitable for use in the vicinity of foodstuffs (in a refrigerator, close to a worktop, etc.), especially because of the oxidation of copper.

Le document DE 34 19 579 A1 décrit un câble plat consistant en un support flexible et des conducteurs connectés à ce support.The document DE 34 19 579 A1 discloses a flat cable consisting of a flexible support and conductors connected to this support.

Il existe donc un besoin pour l'Homme du métier de disposer de lignes d'alimentation plus pratiques à installer et utiliser.There is therefore a need for those skilled in the art to have more convenient feed lines to install and use.

1. Objectifs de l'invention1. Objectives of the invention

L'invention vise à pallier au moins certains des inconvénients des lignes d'alimentation connues.The invention aims to overcome at least some of the disadvantages of known feed lines.

En particulier, l'invention vise aussi à fournir, dans au moins un mode de réalisation de l'invention, une ligne d'alimentation permettant une installation facile d'un réseau d'alimentation électrique.In particular, the invention also aims to provide, in at least one embodiment of the invention, a power line for easy installation of a power supply network.

L'invention vise aussi à fournir, dans au moins un mode de réalisation, une ligne d'alimentation permettant un refroidissement rapide de ses composants.The invention also aims to provide, in at least one embodiment, a feed line for rapid cooling of its components.

L'invention vise aussi à fournir, dans au moins un mode de réalisation de l'invention, une ligne d'alimentation adaptée à un usage à proximité de denrées alimentaires.The invention also aims to provide, in at least one embodiment of the invention, a feed line suitable for use in the vicinity of foodstuffs.

L'invention vise aussi à fournir, dans au moins un mode de réalisation de l'invention, une ligne d'alimentation adaptée pour être repositionnable.The invention also aims to provide, in at least one embodiment of the invention, a feed line adapted to be repositionable.

2. Exposé de l'invention2. Presentation of the invention

Pour ce faire, l'invention concerne une ligne d'alimentation électrique, comprenant :

  • deux conducteurs,
  • un revêtement isolant, protégeant les conducteurs,
  • les conducteurs sont chacun formés d'un ruban plat en aluminium,
  • le revêtement isolant est formé d'une première bande plane et d'une deuxième bande plane, la première bande plane et la deuxième bande plane prenant en sandwich les conducteurs,
  • la première bande plane comprend en outre une couche adhésive de sorte à pouvoir coller la ligne d'alimentation sur un support,
caractérisée en ce qu'elle comprend au moins une bandelette de protection, disposée entre chaque conducteur et la deuxième bande plane dudit revêtement isolant.To do this, the invention relates to a power supply line, comprising:
  • two drivers,
  • an insulating coating, protecting drivers,
  • the conductors are each formed of an aluminum flat ribbon,
  • the insulating coating is formed of a first flat strip and a second flat strip, the first flat strip and the second flat strip sandwiching the conductors,
  • the first flat strip further comprises an adhesive layer of so that you can stick the power line on a support,
characterized in that it comprises at least one protective strip disposed between each conductor and the second flat strip of said insulating coating.

Une ligne d'alimentation selon l'invention est donc composée d'éléments plats superposés qui permettent d'obtenir une ligne d'alimentation plate, pouvant être installée facilement et présentant un encombrement faible lorsqu'elle est collée sur un support. La ligne d'alimentation présente donc une sécurité accrue, due à la réduction des risques d'arrachage de la ligne du fait de sa forme plate, ainsi qu'une esthétique et une discrétion améliorée. La ligne d'alimentation peut ainsi par exemple être recouverte facilement de peinture, d'une tapisserie ou de carrelage.A feed line according to the invention is therefore composed of superposed flat elements which make it possible to obtain a flat feed line that can be easily installed and has a small footprint when it is glued to a support. The supply line therefore has increased security, due to the reduced risk of tearing the line because of its flat shape, as well as improved aesthetics and discretion. The supply line can for example be easily covered with paint, a tapestry or tiling.

De plus, le fait que la ligne d'alimentation soit composée uniquement d'éléments plats permet de faciliter la découpe de celle-ci. En effet, si l'épaisseur de la ligne d'alimentation est suffisamment faible, la ligne d'alimentation peut être découpée à l'aide de ciseaux ou d'un cutter. De préférence, la ligne d'alimentation présente une épaisseur inférieure à 1 mm.In addition, the fact that the feed line is composed only of flat elements makes it easier to cut it. Indeed, if the thickness of the supply line is sufficiently low, the feed line can be cut with scissors or a cutter. Preferably, the feed line has a thickness of less than 1 mm.

La ligne d'alimentation découpée à la longueur souhaitée peut ainsi être connectée à un appareil électrique nécessitant une alimentation, soit directement si l'appareil est adapté, soit via une conversion, par exemple vers un câble cylindrique classique ou par la connexion de la ligne d'alimentation à une prise électrique sur laquelle sera branché l'appareil électrique.The power line cut to the desired length can thus be connected to an electrical device requiring a power supply, either directly if the device is adapted, or via a conversion, for example to a conventional cylindrical cable or by the connection of the line. power supply to an electrical outlet to which the electrical appliance will be connected.

Les rubans plats formant les conducteurs transmettent le courant avec une efficacité semblable aux câbles cylindriques classiques, mais disposent d'une plus grande surface de refroidissement que lesdits câbles cylindriques. De préférence, la largeur des conducteurs est au minimum de 8 mm.The flat ribbons forming the conductors transmit the current with an efficiency similar to conventional cylindrical cables, but have a larger cooling surface than said cylindrical cables. Preferably, the width of the conductors is at least 8 mm.

De plus, chaque conducteur est protégé de la deuxième bande plane par la bandelette de protection, dont le matériau peut être choisi spécialement pour interagir le moins possible avec les conducteurs. En outre, dans une variante de l'invention où la deuxième bande plane est reliée à la première bande plane par exemple par de la colle, la bandelette de protection permet d'éviter que les conducteurs soient en contact avec cette colle et donc de réduire les risques de dégradations.In addition, each conductor is protected from the second flat strip by the protective strip, the material of which can be selected specifically to interact as little as possible with the conductors. In addition, in a variant of the invention where the second flat strip is connected to the first flat strip for example by glue, the protective strip prevents the conductors from being in contact with this glue and thus reducing the risks of damage.

Avantageusement, une ligne d'alimentation selon l'invention comprend une bandelette de protection par conducteur, chaque bandelette étant disposée entre un conducteur et la deuxième bande plane et étant de même largeur que ce conducteur.Advantageously, a feed line according to the invention comprises a protective strip by conductor, each strip being arranged between a conductor and the second flat band and being of the same width as this conductor.

Avantageusement et selon l'invention, la couche adhésive est une couche adhésive repositionnable.Advantageously and according to the invention, the adhesive layer is a repositionable adhesive layer.

Selon cet aspect de l'invention, la ligne d'alimentation est ainsi repositionnable, permettant ainsi la mise en place et la modification rapide et facile d'un réseau d'alimentation.According to this aspect of the invention, the power line is repositionable, allowing the establishment and the quick and easy modification of a power supply network.

Avantageusement et selon l'invention, la deuxième bande plane est translucide.Advantageously and according to the invention, the second flat strip is translucent.

Selon cet aspect de l'invention, les conducteurs sont ainsi visibles à travers la deuxième bande plane, ce qui facilite les opérations de pose de la ligne d'alimentation, notamment au niveau des découpes et des connexions des lignes d'alimentation aux appareils à alimenter.According to this aspect of the invention, the conductors are thus visible through the second flat strip, which facilitates the laying operations of the supply line, particularly at the cutouts and connections of the supply lines to the apparatuses. feed.

L'invention concerne également un réseau d'alimentation caractérisé en ce qu'il comprend au moins une ligne d'alimentation selon l'invention reliée d'une part à une source d'alimentation électrique et d'autre part à une prise électrique.The invention also relates to a power supply network characterized in that it comprises at least one power supply line according to the invention connected on the one hand to a power supply source and on the other hand to an electrical outlet.

Un réseau d'alimentation selon l'invention permet donc de relier un appareil électrique à une source d'alimentation via un réseau électrique comprenant des lignes d'alimentation selon l'invention, permettant ainsi une installation aisée et une sécurité accrue.A power supply network according to the invention thus makes it possible to connect an electrical appliance to a power source via an electrical network comprising supply lines according to the invention, thus allowing easy installation and increased safety.

De préférence, au moins une ligne d'alimentation et une prise électrique à laquelle la ligne d'alimentation est reliée sont repositionnables, permettant ainsi de reconfigurer à volonté le réseau électrique, afin de satisfaire à un besoin temporaire ou permanent d'alimentation électrique dans une zone particulière d'une habitation par exemple.Preferably, at least one power supply line and an electrical outlet to which the supply line is connected are repositionable, thus allowing the electrical network to be reconfigured at will, in order to satisfy a temporary or permanent power supply requirement in a particular area of a dwelling for example.

Les réalisations suivantes sont des exemples. Bien que la description se réfère à un ou plusieurs modes de réalisation, ceci ne signifie pas nécessairement que chaque référence concerne le même mode de réalisation, ou que les caractéristiques s'appliquent seulement à un seul mode de réalisation. De simples caractéristiques de différents modes de réalisation peuvent également être combinées pour fournir d'autres réalisations. Sur les figures, les échelles et les proportions ne sont pas strictement respectées et ce, à des fins d'illustration et de clarté.The following achievements are examples.

The power line 10 can thus be easily installed in a kitchen for example, at a work plane.

Le fait que les rubans soient plats permet en outre un refroidissement plus efficace des conducteurs 12a, 12b, par rapport à un câble de l'art antérieur dont la forme entraine une difficulté de refroidissement du fait de la concentration de la masse du câble.The fact that the tapes are flat also allows a more efficient cooling of the conductors 12a, 12b, compared to a cable of the prior art whose shape causes a difficulty of cooling due to the concentration of the mass of the cable.

Sur le mode de réalisation représenté sur la figure 1, les conducteurs 12a, 12b sont chacun recouverts d'une bandelette de protection 16a, 16b sur toute leur longueur. Les bandelettes 16a, 16b de protection sont par exemple en plastique et présentent des caractéristiques permettant de limiter la dégradation des conducteurs 12a, 12b. Les parties hachurées représentent, une partie des conducteurs 12a, 12b n'étant pas recouverte de bandelettes de protection. Cette partie est située au bout d'une ligne de transmission et est adaptée pour être connectée à d'autres éléments électriques, tel que par exemple des prises électriques, comme décrit plus loin en référence avec la figure 3.In the embodiment shown on the figure 1 , the conductors 12a, 12b are each covered with a protective strip 16a, 16b along their entire length. The strips 16a, 16b of protection are for example plastic and have characteristics to limit the degradation of the conductors 12a, 12b. The hatched portions represent, a portion of the conductors 12a, 12b not being covered with protective strips. This part is located at the end of a transmission line and is adapted to be connected to other electrical elements, such as electrical sockets, for example, as described later with reference to FIG. figure 3 .

Les conducteurs 12a, 12b et les bandelettes 16a, 16b de protection sont pris en sandwich par la première bande 14 plane et une deuxième bande plane, représentée en référence avec la figure 2, la première bande 14 plane et la deuxième bande plane formant un revêtement isolant, permettant de protéger les conducteurs 12a, 12b de l'environnement extérieur (corrosion, découpe accidentelle, etc.) et l'environnement extérieur des conducteurs 12a, 12b, du fait du passage d'électricité dans les conducteurs 12a, 12b lorsque que la ligne 10 d'alimentation alimente un appareil électrique. La deuxième bande plane recouvrant les conducteurs 12a, 12b et les bandelettes 16a, 16b de protection, elle n'est pas représentée sur la figure 1 pour des raisons de clarté.The conductors 12a, 12b and the protective strips 16a, 16b are sandwiched by the first flat strip 14 and a second flat strip, shown with reference to FIG. figure 2 , the first flat strip 14 and the second flat strip forming an insulating coating, making it possible to protect the conductors 12a, 12b from the external environment (corrosion, accidental cutting, etc.) and the external environment of the conductors 12a, 12b, makes the passage of electricity in the conductors 12a, 12b when the power supply line 10 supplies an electrical device. The second flat strip covering the conductors 12a, 12b and the strips 16a, 16b protection, she is not represented on the figure 1 for the sake of clarity.

La figure 2 représente schématiquement en coupe selon X-X la ligne 10 d'alimentation représentée en référence avec la figure 1. Sur cette figure 2, les épaisseurs des éléments représentés sont accentuées pour des raisons de clarté. En pratique, les conducteurs 12a, 12b, la première bande 14 plane, la deuxième bande 18 plane et les bandelettes 16a, 16b de protections ont généralement une épaisseur inférieure à 0,5 mm, et la ligne 10 d'alimentation a une épaisseur totale inférieure à 1 mm pour une largeur supérieure à 8 mm.The figure 2 represents schematically in section along XX the feed line 10 represented with reference to FIG. figure 1 . On this figure 2 , the thicknesses of the elements represented are accentuated for the sake of clarity. In practice, the conductors 12a, 12b, the first flat strip 14, the second flat strip 18 and the strips 16a, 16b of protections generally have a thickness of less than 0.5 mm, and the supply line 10 has a total thickness less than 1 mm for a width greater than 8 mm.

La deuxième bande 18 plane est visible sur cette figure 2, et forme avec la première bande 14 plane un revêtement isolant prenant en sandwich les conducteurs 12a, 12b et les bandelettes 16a, 16b de protection. Sur la figure 2, la deuxième bande 18 plane est légèrement courbée du fait de la présence des conducteurs 12a, 12b et des bandelettes 16a, 16b de protection formant deux excroissances sur la première bande 14 plane. En pratique, ces excroissances ont une épaisseur faible par rapport à la largeur de la deuxième bande 18 plane, et la courbure est donc négligeable.The second flat strip 18 is visible on this figure 2 and forms with the first strip 14 an insulating coating sandwiching the conductors 12a, 12b and the strips 16a, 16b protection. On the figure 2 , the second flat strip 18 is slightly curved due to the presence of the conductors 12a, 12b and the strips 16a, 16b protection forming two protuberances on the first strip 14 plane. In practice, these protuberances have a small thickness relative to the width of the second flat strip 18, and the curvature is negligible.

La deuxième bande 18 plane peut être opaque ou translucide, selon l'utilisation visée. Dans un mode de réalisation où la deuxième bande 18 plane est transparente, les bandelettes 16a, 16b de protection sont visibles à travers la deuxième bande 18 plane, comme représenté par exemple sur les lignes d'alimentation d'un réseau d'alimentation décrit en référence avec la figure 3. La possibilité de voir la position des bandelettes 16a, 16b de protection et des conducteurs 12a, 12b permet de faciliter les interventions techniques sur la ligne telle que par exemple les découpes et la détection de défaut sur la ligne 10 d'alimentation. Les bandelettes 16a, 16b de protection peuvent en outre être colorées pour différencier les deux conducteurs qu'ils protègent.The second flat strip 18 may be opaque or translucent, depending on the intended use. In one embodiment where the second flat strip 18 is transparent, the protective strips 16a, 16b are visible through the second flat strip 18, as shown for example on the supply lines of a supply network described in FIG. reference with the figure 3 . The possibility of seeing the position of the protective strips 16a, 16b and the conductors 12a, 12b makes it possible to facilitate technical interventions on the line such as, for example, the cuts and the fault detection on the supply line. The strips 16a, 16b of protection may also be colored to differentiate the two conductors that they protect.

La deuxième bande 18 plane est par exemple fixée à la première bande 14 plane et aux bandelettes 16a, 16b de protection grâce à de la colle. Les bandelettes 16a, 16b de protection permettent ainsi d'éviter que les conducteurs 12a, 12b soient en contact avec cette colle, garantissant ainsi leur efficacité électrique.The second flat strip 18 is for example fixed to the first flat strip 14 and the strips 16a, 16b of protection by glue. The protective strips 16a, 16b thus make it possible to prevent the conductors 12a, 12b from being in contact with this adhesive, thereby guaranteeing their electrical efficiency.

Selon un autre mode de réalisation de l'invention, la ligne 10 d'alimentation ne comprend pas de bandelette de protection. Les conducteurs 12a, 12b sont ainsi directement en contact avec la deuxième bande 18 plane.According to another embodiment of the invention, the supply line does not include a protective strip. The conductors 12a, 12b are thus directly in contact with the second flat strip 18.

Selon un autre mode de réalisation de l'invention, la ligne 10 d'alimentation comprend une seule bandelette de protection, suffisamment large pour recouvrir les deux conducteurs 12a, 12b.According to another embodiment of the invention, the feed line comprises a single protective strip, sufficiently wide to cover the two conductors 12a, 12b.

La première bande 14 plane comprend en outre, sur une de ses faces opposée à une face où se trouvent les conducteurs 12a, 12b, une couche 19 adhésive permettant de coller la ligne 10 d'alimentation sur un support. De préférence, cette couche 19 adhésive est repositionnable, de façon à ce que la ligne 10 d'alimentation soit repositionnable permettant ainsi une grande flexibilité d'installation.The first flat strip 14 further comprises, on one of its faces opposite a face where the conductors 12a, 12b are located, an adhesive layer 19 for bonding the supply line 10 to a support. Preferably, this adhesive layer 19 is repositionable, so that the supply line is repositionable thereby allowing great flexibility of installation.

La ligne d'alimentation est ainsi fabriquée selon le procédé suivant :

  • les rubans plats en aluminium formant les conducteurs 12a, 12b sont déposés sur la première bande 14 plane,
  • les conducteurs 12a, 12b sont recouverts par les bandelettes 16a, 16b de protection,
  • les conducteurs 12a, 12b et les bandelettes 16a, 16b de protection sont pris en sandwich par le première bande 14 plane et la deuxième bande 18 plane,
  • la couche 19 adhésive est fixée sur la première bande 14 plane.
The feed line is thus manufactured according to the following method:
  • the flat aluminum strips forming the conductors 12a, 12b are deposited on the first flat strip 14,
  • the conductors 12a, 12b are covered by the strips 16a, 16b of protection,
  • the conductors 12a, 12b and the protective strips 16a, 16b are sandwiched by the first flat strip 14 and the second flat strip 18,
  • the adhesive layer 19 is fixed on the first flat strip 14.

La figure 3 représente schématiquement un réseau 20 d'alimentation selon un mode de réalisation de l'invention.The figure 3 schematically shows a power supply network according to one embodiment of the invention.

Le réseau 20 d'alimentation comprend deux prises 21a, 21b électriques de type femelle, reliées à une source 22 d'alimentation par le biais de lignes 10a, 10b, 10c, 10d d'alimentation selon le mode de réalisation de l'invention décrit en référence aux figures 1 et 2. Pour permettre l'alimentation de deux prises 21a, 21b électriques par une seule source 22 d'alimentation, le réseau 20 d'alimentation comprend en outre un boitier 24 de dérivation. Le réseau 20 d'alimentation comprend aussi un boitier 26 de contact permettant de relier deux lignes 10c, 10d d'alimentation formant un angle droit. La source 22 d'alimentation est par exemple une source autonome, ou bien est reliée au réseau central d'un logement. Le boitier 24 de dérivation, le boitier 26 de contact et les prises 21a, 21b électriques sont spécifiquement adaptées pour la connexion avec la ligne de transmission.The power supply network comprises two female-type electrical sockets 21a, 21b, connected to a supply source 22 via supply lines 10a, 10b, 10c, 10d according to the embodiment of the invention described. with reference to Figures 1 and 2 . To allow two power sockets 21a, 21b to be powered by a single supply source 22, the supply network 20 further comprises a branch box 24. The power supply network 20 also comprises a contact housing 26 for connecting two feeder lines 10c, 10d forming a right angle. The power source 22 is for example an autonomous source, or is connected to the central network of a housing. The branch box 24, the contact housing 26 and the electrical sockets 21a, 21b are specifically adapted for connection with the transmission line.

Les prises 21a, 21b électriques, la source 22 d'alimentation, les lignes 10a, 10b, 10c, 10d d'alimentation et les boitiers 24, 26 sont disposés sur un support 28, par exemple un mur ou un meuble.The electrical jacks 21a, 21b, the supply source 22, the supply lines 10a, 10b, 10c, 10d and the boxes 24, 26 are arranged on a support 28, for example a wall or a piece of furniture.

De préférence, les prises 21a, 21b électriques et les boitiers 24, 26 sont chacun fixés au support 28 par un adhésif repositionnable (non représenté), et la couche adhésive des lignes 10a, 10b, 10c, 10d d'alimentation est repositionnable. Ainsi, les éléments du réseau 20 d'alimentation peuvent être facilement déplacés afin de former différentes configurations du réseau 20 d'alimentation. En outre, d'autres boitiers de dérivation, boitiers de contact, lignes d'alimentation et prise électrique peuvent être facilement ajoutés, retirés ou déplacés en fonction des besoins.Preferably, the electrical sockets 21a, 21b and the boxes 24, 26 are each fixed to the support 28 by a repositionable adhesive (not shown), and the adhesive layer of the supply lines 10a, 10b, 10c, 10d is repositionable. Thus, the power grid elements can be easily moved to form different configurations of the power grid. In addition, other bypass boxes, contact boxes, power lines, and electrical outlets can be easily added, removed, or moved as needed.

La figure 3 représente également, relié à la source 22 d'alimentation, un câble 30 cylindrique selon l'art antérieur. Le câble 30 est maintenu au support par une attache 32, difficilement détachable, et le câble 30 n'est pas totalement en contact du support ce qui entraine des risques d'arrachage. La ligne 10 d'alimentation selon l'invention est donc plus avantageuse que le câble 30 de l'art antérieur.The figure 3 also shows, connected to the supply source 22, a cylindrical cable 30 according to the prior art. The cable 30 is held in the support by a fastener 32, hardly detachable, and the cable 30 is not fully in contact with the support which causes risks of tearing. The supply line 10 according to the invention is therefore more advantageous than the cable 30 of the prior art.
