Description
La présente invention concerne un câble plat comportant au moins deux conducteurs enrobés dans une gaine isolante. Un tel câble est connu du document DE-A-2 811 452.The present invention relates to a flat cable comprising at least two conductors embedded in an insulating sheath. Such a cable is known from document DE-A-2 811 452.
Les câbles plats connaissent un succès commercial de plus en plus important parce qu'ils se prêtent bien à une mécanisation des opérations de raccordement. En effet, la gaine isolante et, le cas échéant, l'isolation périphérique des conducteurs peuvent être perforées au moyen d'un dispositif approprié, et les appareils tels que prises, interrupteurs, etc. peuvent être raccordés directement à travers ces perforations par l'intermédiaire de contacts autodénudants.Flat cables are enjoying increasing commercial success because they lend themselves to mechanization of connection operations. Indeed, the insulating sheath and, if necessary, the peripheral insulation of the conductors can be perforated by means of an appropriate device, and devices such as sockets, switches, etc. can be connected directly through these perforations via insulation displacement contacts.
Ce type de raccordement est utilisé dans un grand nombre d'installations domestiques ou professionnelles, les câbles étant logés dans des goulottes ou des chemins de câble apparents et les appareils étant disposés à proximité ou à cheval sur ces goulottes ou ces chemins de câble. Une telle utilisation ne pose habituellement aucun problème. Les difficultés apparaissent lorsqu'il s'agit d'insérer ces câbles plats dans des conduits tubulaires ou des tubes cylindriques standards. Les frictions sont telles qu'il devient quasiment impossible de les tirer dans ces conduits, ce qui constitue un inconvénient qui limite leur utilisation, par ailleurs fort pratique.This type of connection is used in a large number of domestic or professional installations, the cables being housed in trunking or visible cable trays and the devices being placed close to or straddling these trunking or cable trays. Such use is usually not a problem. The difficulties arise when it comes to inserting these flat cables into tubular conduits or standard cylindrical tubes. Frictions are such that it becomes almost impossible to pull them in these conduits, which constitutes a drawback which limits their use, which is also very practical.
Pour des raisons différentes, en particulier pour protéger les câbles plats qui sont considérés comme étant fragiles, pour réduire leur encombrement et faciliter leur pliage dans une direction quelconque, on a proposé de les enrouler en spirale. Un tel enroulement, décrit dans la publication française N° 2 513 801 A1 ne donne pas satisfaction pour résoudre les problèmes posés parce qu'aucun moyen n'est prévu pour maintenir le câble dans la position enroulée. Or il est évident que l'enroulement en spirale aura tendance à s'ouvrir s'il n'est pas maintenu par des brides ou des moyens de serrage disposés transversalement par rapport à l'axe du câble. De telles brides ne peuvent que gêner l'insertion du câble plat enroulé dans un conduit tubulaire, ce qui va à l'encontre de la solution recherchée.For different reasons, in particular to protect the flat cables which are considered to be fragile, to reduce their bulk and facilitate their folding in any direction, it has been proposed to wind them in a spiral. Such a winding, described in French publication No. 2,513,801 A1 is not satisfactory for solving the problems posed because no means is provided for keeping the cable in the wound position. Now it is obvious that the spiral winding will tend to open if it is not held by flanges or clamping means arranged transversely to the axis of the cable. Such flanges can only hinder the insertion of the flat cable wound in a tubular conduit, which goes against the desired solution.
Le document DE-A-2 811 452 décrit un câble plat comportant une gaine isolante ayant aux extrémités des moyens d'accouplement autorisant un enroulement du câble sur lui-même pour obtenir une forme tubulaire. Un tel tube ne possède pas la rigidité suffisante pour le passage et l'introduction dans un conduit cylindrique.Document DE-A-2 811 452 describes a flat cable comprising an insulating sheath having at the ends coupling means allowing a winding of the cable on itself to obtain a tubular shape. Such a tube does not have sufficient rigidity for passage and introduction into a cylindrical conduit.
L'objet de l'invention consiste à faciliter le passage des câbles dans les conduits.The object of the invention is to facilitate the passage of cables in conduits.
Le câble plat selon l'invention comportant au moins deux conducteurs enrobés dans une gaine isolante, laquelle est équipée de moyens d'accouplement disposés sur ses bords latéraux, ces moyens étant agencés pour lier de façon amovible lesdits bords latéraux lorsqu'ils ont été préalablement juxtaposés suite à un enroulement du câble sur lui-même autour de son axe longitudinal, la gaine isloante comporte des canaux tubulaire de logement des conducteurs, et des ports souples de liaison entre les canaux, est caractérisé en ce que lesdits canaux comportent chacun une série de nervures et de gorges longitudinales ménagées sur une des faces du câble, les nervures étant agençées pour s'engager dans les gorges correspondantes lorsque le câble est enroulé sur lui-même autour de son axe longitudinal.The flat cable according to the invention comprising at least two conductors encased in an insulating sheath, which is equipped with coupling means arranged on its lateral edges, these means being arranged to removably link said lateral edges when they have been previously juxtaposed following a winding of the cable on itself around its longitudinal axis, the insulating sheath comprises tubular channels for housing the conductors, and flexible ports for connection between the channels, is characterized in that said channels each comprise a series longitudinal ribs and grooves formed on one of the faces of the cable, the ribs being arranged to engage in the corresponding grooves when the cable is wound on itself around its longitudinal axis.
Selon un mode de réalisation particulièrement avantageux, lesdits moyens comportent au moins un premier élément disposé sur l'un desdits bords latéraux du câble et au moins un second élément disposé sur l'autre desdits bords latéraux de ce câble, ces deux éléments comportant des organes d'accrochage complémentaires.According to a particularly advantageous embodiment, said means comprise at least a first element disposed on one of said lateral edges of the cable and at least one second element disposed on the other of said lateral edges of this cable, these two elements comprising members additional attachment.

En référence à la figure 1, le câble plat 10 comporte par exemple trois conducteurs 11, 12 et 13 cylindriques entourés d'un champ isolant respectivement 11a, 12a, 13a sous forme d'une gaine de section annulaire. Ces conducteurs isolés sont enrobés dans une gaine isolante 14 qui comporte des moyens d'accouplement disposés sur ses bords latéraux pour permettre, comme le montre plus particulièrement la figure 2, de lier ces bords de façon amovible lorsqu'ils ont été préalablement juxtaposés en enroulant le câble sur lui-même autour de son axe longitudinal.Referring to Figure 1, the
Ladite gaine 14 comporte en fait des canaux tubulaires 14a, 14b et 14c, dont le nombre correspond à celui des conducteurs 11, 12 et 13, chacun de ces derniers étant logé dans un desdits canaux. Ces canaux sont liés deux à deux par des ponts souples 15 dont l'épaisseur est sensiblement réduite par rapport à celle des canaux, afin de faciliter l'enroulement du câble sur lui-même.Said
Les moyens d'accouplement sont avantageusement constitués par un premier élément 16 disposé sur l'un des bords latéraux de la gaine 14 et d'un deuxième élément 17 disposé sur l'autre bord latéral de la gaine 14. Dans l'exemple représenté, le premier élément 16 comporte un organe d'accrochage 16a présentant un profil en forme de crochet qui fait partie ou constitue ledit élément et le second élément 17 comporte un organe d'accrochage 17a comprenant un creux dans lequel peut être encastré l'organe d'accrochage 16a.The coupling means advantageously consist of a
La figure 2 montre bien comment ledit organe d'accrochage 16a s'engage dans ledit organe d'accrochage 17a pour assurer la liaison des bords latéraux du câble, lorsque ce dernier a été enroulé sur lui-même comme mentionné précédemment.FIG. 2 clearly shows how said attachment member 16a engages in said
Il est certain que le nombre de conducteurs n'est pas limité. De même ces conducteurs peuvent être des conducteurs électriques ou des conducteurs de lumière. Enfin, ils peuvent être nus ou isolés. Dans la forme de réalisation décrite, ces conducteurs sont doublement isolés puisqu'ils sont enrobés dans un isolant de section annulaire, lui-même enrobé dans la gaine isolante 14.It is certain that the number of drivers is not limited. Likewise, these conductors can be electrical conductors or light conductors. Finally, they can be naked or isolated. In the embodiment described, these conductors are doubly insulated since they are coated in an insulator of annular section, itself coated in the
Les figures 3 et 4 montrent le câble des figures précédentes dans les deux états dans lesquels il est destiné à être utilisé, à savoir un état déroulé, correspondant à une utilisation classique d'un câble plat et un état enroulé facilitant l'insertion dans un conduit tubulaire.Figures 3 and 4 show the cable of the previous figures in the two states in which it is intended to be used, namely an unwound state, corresponding to a conventional use of a flat cable and a coiled state facilitating insertion into a tubular conduit.
On notera que la gaine 14 présente une face lisse et une face pourvue de nervures longitudinales 18 séparées par des gorges 19. Ces nervures et ces gorges sont prévues pour définir le positionnement relatif des canaux 14a, 14b, 14c lorsque le câble est dans son état enroulé, comme le montrent les figures 2 et 4. Les nervures 18 s'engagent dans les gorges 19, ce qui contribue à maintenir les canaux 14a, 14b et 14c et de ce fait les conducteurs 11, 12 et 13 dans une position stable et parfaitement définie à l'intérieur de la gaine 14 enroulée.It will be noted that the
Les moyens d'accrochage peuvent se présenter sous diverses variantes. Ils peuvent être continus ou discontinus le long des bords latéraux de la gaine 14. Dans le cas où ils sont discontinus, ils peuvent comporter des protubérances et des cavités régulièrement espacées, les protubérances étant agencées pour s'engager dans les cavités correspondantes pour produire un accouplement du type à bouton-pression. Cet accouplement peut également être réalisé au moyen de substances adhésives. Enfin, on peut envisager l'utilisation de surfaces d'accrochage à crochets et boucles miniatures du type Velcro®.The attachment means can come in various variants. They can be continuous or discontinuous along the lateral edges of the
Tous ces moyens permettent d'atteindre le même résultat, à savoir la liaison temporaire ou permanente des bords latéraux d'un câble plat pour le configurer en câble rond afin de faciliter son insertion dans des conduits tubulaires.All these means make it possible to achieve the same result, namely the temporary or permanent connection of the lateral edges of a flat cable to configure it as a round cable in order to facilitate its insertion into tubular conduits.
La figure 5 représente une vue en coupe d'un câble plat dans lequel sont représentés à titre d'exemples, divers modes de réalisation destinés à des utilisations variées. Dans une même gaine 14, qui est similaire à celle décrite ci-dessus, sont logés un câble coaxial 20, un câble téléphonique 21 à quatre paires torsadées et un câble optique 22 à deux fibres optiques. Il est bien entendu que ces différents câbles peuvent se trouver seuls dans une gaine 14 ou en combinaison comme cela est représenté. En outre, la gaine peut être pourvue d'une tresse métallique 23 intégrée qui constitue un blindage presque intégral du câble plat lorsqu'il est amené dans son état enroulé.FIG. 5 represents a sectional view of a flat cable in which are represented by way of examples, various embodiments intended for various uses. In the
Grâce à une combinaison telle que représentée, le câble plat 10 devient un câble multifonction qui se prête bien aux opérations de raccordement automatisé tout en se prêtant à une pose classique dans des conduits cylindriques.Thanks to a combination as shown, the
