Description
L1invention a pour objet un procédé pour la fabrication des câbles électriques plats, à plusieurs conduc dans Xarillètles noya dans un profil extrudé de matière isolante/de section quelconque, dans lesquels cette matière assure à la fois le positionnement et l'isolation des conducteurs entre eux. The invention relates to a process for the manufacture of flat electrical cables, with several conduits in Xarilletles embedded in an extruded profile of insulating material / of any cross-section, in which this material ensures both the positioning and the insulation of the conductors between them .
ta difficulté principale que l'on rencontre dans cette fabrication consiste à conserver ltordonnancement désiré des fils conducteurs qui doivent se trouver dans un même plan avec un espacement déterminé et constant entre fils voisins à l'intérieur du câble terminé. your main difficulty encountered in this manufacture consists in keeping the desired ordering of the conductive wires which must be in the same plane with a determined and constant spacing between neighboring wires inside the finished cable.
Selon le procédé de l'invention, on produit séparément à partir de deux extrudeuses distinctes deux flux de matière électriquement isolante qui sont dirigés dans un premier et dans un deuxième plans parallèles de part et d'autre d'un troisième plan dans lequel est constituée une nappe des fils conducteurs. lies deux flux sont envoyés dès leur sortie des filières dans des directions les rapprochant puis ils se rejoignent à l'état fondu en se recouvrant et en enfermant entre eux la nappe des fils conducteurs,
De préférence, les flux extrudés en matière isolante sont produits d'un cssté et de l'autre de la nappe des fils conducteurs dans des directions faisant chacune un angle avec la direction de la nappe des fils conducteurs.According to the method of the invention, two streams of electrically insulating material are produced separately from two separate extruders which are directed in a first and in a second parallel planes on either side of a third plane in which is constituted a layer of conductive wires. the two streams are sent as soon as they leave the dies in directions bringing them together then they join in the molten state by overlapping and enclosing between them the sheet of conducting wires,
Preferably, the extruded flows of insulating material are produced from one side and from the other of the ply of conductive wires in directions each making an angle with the direction of the ply of conductive wires.
Selon un mode préféré de mise en oeuvre de l'invention, la matière isolante est extrudée d'un côté et de l'autre d'un plan de symétrie passant par la ligne centrale de la nappe des fils conducteurs et perpendiculaire à cette nappe, les deux flux de matière isolante étant d'abord envoyés dans des directions les rapprochant de ce plan de symétrie et les rapprochant eux#meAmes, puis mis sous forme de rubans en étant conduits l'un vers l'autre pour qu'ils se rejoignent en rencontrant la nappe des fils conducteurs. According to a preferred embodiment of the invention, the insulating material is extruded on one side and on the other from a plane of symmetry passing through the central line of the sheet of conductive wires and perpendicular to this sheet, the two insulating material flows being first sent in directions bringing them closer to this plane of symmetry and bringing them closer # meAmes, then put in the form of ribbons by being led towards each other so that they meet by meeting the layer of conductive wires.
L'invention a aussi pour objet une tête d'extrusion servant à la mise en oeuvre du procédé, dont la construction est simplifiée et le réglage facile en conséquence précisément de ce procédé. The invention also relates to an extrusion head used for the implementation of the method, the construction of which is simplified and the easy adjustment consequently precisely of this method.
Pour mieux faire comprendre l'invention, on donnera maintenant une description d'une tête d'extrusion conforme à un mode préféré de réalisation. On se reportera aux dessins annexés dans lesquels
- la figure I est une vue de dessus d'une tête d'extrusion selon l'invention,
- la figure 2 est une vue de l'extrémité de la sortie du câble terminé de la tête de la figure 1,
- la figure 3 est une vue en coupe selon
III-III de la figure 2,
- la figure 4 est une vue partielle agrandie en coupe selon IV-IV de la figure 3.To better understand the invention, a description will now be given of an extrusion head according to a preferred embodiment. Reference is made to the accompanying drawings in which
FIG. I is a top view of an extrusion head according to the invention,
FIG. 2 is a view of the end of the outlet of the finished cable from the head of FIG. 1,
- Figure 3 is a sectional view along
III-III of Figure 2,
- Figure 4 is an enlarged partial view in section on IV-IV of Figure 3.
Une tête d'extrusion permettant la mise en oeuvre du procédé de l'invention selon un mode préféré de réalisation comprend un corps 1 ayant à une extrémité un orifice 2 de sortie d'un câble électrique profilé à multiconducteurs et à l'extrémité opposée trois entrées, respectivement une entrée 3 pour une nappe de fils conducteurs parallèles, une entrée 4 pour un premier flux de matière isolante, une entrée 5 pour un deuxième flux de matière isolante. An extrusion head allowing the implementation of the process of the invention according to a preferred embodiment comprises a body 1 having at one end an orifice 2 for the outlet of a profiled electrical cable with multiconductors and at the opposite end three inputs, respectively an input 3 for a sheet of parallel conductive wires, an input 4 for a first flow of insulating material, an input 5 for a second flow of insulating material.
Sur la figure 2, le plan de coupe III-III est perpendiculaire au plan de la nappe des fils conducteurs qui arrive à l'entrée 3 ; de plus ce plan de coupe passe par la ligne centrale de cette nappe et de l'entrée 3o il constitue donc un plan de symétrie de la nappe des fils et de l'entrée 3. Dans l'exemple décrit ici, les entrées 4 et 5 des flux en matière isolante sont disposées de part et d'autre de ce plan de symétrie qui est symbolisé par un trait mixte 6 sur la figure 1.De plus, les entrées 4 et 5 sont situées chacune respectivement dans un premier et dans un deuxième plan qui sont parallèles au plan de l'entrée 3 de la nappe des fils conducteurs et qui sont situés de part et d'autre de ce plan de l'entrée 3, comme on le voit sur la figure 20 En outre, les entrées 4 et 5 sont disposées dans des directions qui font chacune un angle a de 450 avec le plan de symétrie 6 et qui se rapprochent de ce plan 6 comme le montre la figure 1. In FIG. 2, the section plane III-III is perpendicular to the plane of the ply of the conducting wires which arrives at the inlet 3; in addition, this cutting plane passes through the central line of this ply and of the input 3o, it therefore constitutes a plane of symmetry of the ply of the wires and of the input 3. In the example described here, the inputs 4 and 5 flows of insulating material are arranged on either side of this plane of symmetry which is symbolized by a dashed line 6 in Figure 1. In addition, the inputs 4 and 5 are each located respectively in a first and in a second plane which are parallel to the plane of the input 3 of the sheet of conductive wires and which are located on either side of this plane of the input 3, as seen in FIG. 20 In addition, the inputs 4 and 5 are arranged in directions which each make an angle a of 450 with the plane of symmetry 6 and which approach this plane 6 as shown in FIG. 1.
Les entrées 4, 5 sont destinées à être raccordées chacune directement à la sortie d'une première et d'une seconde extrudeuse de matière Isolante, Grace à la disposition adoptée, on remarquera que la tête d'extrusion de l'invention est de longueur faible et de construction simple. The inputs 4, 5 are intended to be connected each directly to the output of a first and a second insulating material extruder. Thanks to the arrangement adopted, it will be noted that the extrusion head of the invention is of length weak and of simple construction.
Chaque entrée 4, 5 est prolongée à l'intérieur du corps 1 par un canal 7, 8, de section appropriée et, avec l'agencement décrit ci-dessus, il arrive forcément que les deux canaux 7, 8 se croisent dans l'espace et se trouvent disposés symétriquement de part et d'autre d'un passage intérieur 9, rectiligne, de circulation de la nappe des fils conducteurs qui s'étend entre entrée 3 et la sortie commune 2. A partir de cette situation, visible sur la figure 3, les canaux 7 8 se dirigent l'un vers l'autre, en restant symétriquement de part et d'autre du passage 9, de manière à se rejoinre avant la sortie commune 2, ainsi que le montre la figure 4.Sur cette dernière, le passage 9 est limité d'une part par une surface plane 10 et d'autre part par une succession d'encoches Il dont chacune desquelles est destinée à guider un fil conducteur. Each inlet 4, 5 is extended inside the body 1 by a channel 7, 8, of appropriate section and, with the arrangement described above, it necessarily happens that the two channels 7, 8 intersect in the space and are arranged symmetrically on either side of an internal passage 9, rectilinear, for circulation of the sheet of conductive wires which extends between inlet 3 and common outlet 2. From this situation, visible on in FIG. 3, the channels 7 8 point towards each other, remaining symmetrically on either side of the passage 9, so as to meet before the common exit 2, as shown in FIG. 4. On the latter, the passage 9 is limited on the one hand by a flat surface 10 and on the other hand by a succession of notches II, each of which is intended to guide a conductive wire.
On notera que la distance à parcourir par la matière injectée entre chaque entrée 4, 5 et la sortie 2 est courte. De plus, les entrées 4, 5 et les canaux intérieurs 7, 8 sont indépendants, ce qui permet leur alimentation sans difficulté par des extrudeuses différentes. Ainsi, les deux flux de matière isolante destinés à contenir les fils conducteurs pourraient avoir, si on le juge utile, des compositions différentes, et, surtout, on peut leur donner des teintes différentes. Un débit convenable des deux canaux 7, 8 est facile à obtenir et à régler à partir de deux extrudeuses distinctes. En outre, en raison de sa simplicité et de sa longueur réduite, on ne rencontre pas de difficulté à réaliser une tête d'extrusion ayant une étanchéité satisfaisante0
Il ressort de la description donnée cidessus d'une tête d'extrusion préférée, que, conformément -au procédé de l'invention, on part de deux extrudeuses distinctes qui envoient dans deux entrées 4, 5 deux flux qui sont dirigés aussitôt dans deux directions les rapprochant l'un de l'autre0
On n'est pas strictement contraint de prévoir les deux entrées 4 et 5 d'un c8té et de l'autre du plan de symétrie 6 perpendiculaire au plan du passage 9 de la nappe des fils conducteurs,
Il est possible, en restant dans l'esprit de l'invention, de situer les deux entrées 4 et 5 de part et d'autre du plan du passage 9 c'est-à-dire juste au-dessus et en-dessous de lten- trée 3. Ceci revient à dire que, dans ce cas, les angles a auraient une valeur nulle, De toute façon, les flux de matière isolante sont mis au profil désiré, par exemple sous forme de rubans quand la matière rejoint le plan de symétrie 6, dans les canaux 7, 80
n est clair aussi que la valeur préférée de 450 mentionnée dans l'exemple décrit pour chacun des deux angles a n'est pas impérative.On pourrait, à l'inverse, adopter une valeur plus grande, par exemple 700 ou 900 ; toutefois, dans un tel cas, on rend moins direct le trajet que doivent suivre les rubans à l'intérieur du corps 1 et on augmente l'en- combrement général de l'ensemble composé des deux extrudeuses raccordées à la tete d'extrusion.It will be noted that the distance to be traveled by the injected material between each inlet 4, 5 and the outlet 2 is short. In addition, the inputs 4, 5 and the internal channels 7, 8 are independent, which allows them to be fed without difficulty by different extruders. Thus, the two flows of insulating material intended to contain the conductive wires could have, if it is deemed useful, different compositions, and, above all, they can be given different colors. A suitable flow rate of the two channels 7, 8 is easy to obtain and to regulate from two separate extruders. In addition, due to its simplicity and reduced length, there is no difficulty in producing an extrusion head having a satisfactory seal.
It emerges from the description given above of a preferred extrusion head, that, in accordance with the method of the invention, one starts from two separate extruders which send two flows 4, 5 into two inlets which are immediately directed in two directions bringing them closer to each other0
It is not strictly constrained to provide the two inputs 4 and 5 with one side and the other with the plane of symmetry 6 perpendicular to the plane of the passage 9 of the sheet of conductive wires,
It is possible, while remaining in the spirit of the invention, to locate the two entrances 4 and 5 on either side of the plane of passage 9, that is to say just above and below lten- trée 3. This amounts to saying that, in this case, the angles a would have a zero value. In any case, the fluxes of insulating material are set to the desired profile, for example in the form of tapes when the material joins the plane. symmetry 6, in channels 7, 80
It is also clear that the preferred value of 450 mentioned in the example described for each of the two angles a is not imperative. We could, conversely, adopt a larger value, for example 700 or 900; however, in such a case, the path that the ribbons must follow inside the body 1 is made less direct and the overall dimensions of the assembly made up of the two extruders connected to the extrusion head are increased.
Lorsque l'angle a n'a pas une valeur nulle mais une valeur avantageuse en pratique pouvant se situer entre 200 et 600, on notera que chacun des canaux 7, 8 qui guident la matière isolante présente un seul coude de valeur supplémentaire à celle de l'angle a adoptée, Chaque coude assure le raccordement entre deux trajets qui sont substantiellement rectilignes. When the angle a does not have a zero value but an advantageous value in practice which can be between 200 and 600, it will be noted that each of the channels 7, 8 which guide the insulating material has a single bend of value additional to that of the angle adopted, Each bend ensures the connection between two paths which are substantially rectilinear.
Ceci montre bien la simplicité qu'apporte le procédé de l'in Invention
Un autre avantage du procédé de l'invention est qu'il se prête particulièrement bien à l'emploi de résine thermoplastique fluorée comme matière isolante, par exemple ltéthylènetétrafluoroéthylène (ETFE), le fluoréthylènepropylène (FEZ) ou les résines fluorocarbonées perfluoroalkoxy (PFA),
L'invention s'étend donc aussi à tout câble électrique plat à multiconducteurs dont la matière isolante est une résine thermoplastique fluorée, ou dans lequel les conducteurs sont contenus entre deux rubans de matières isolantes différentes par leur nature et/ou par leur couleur, This clearly shows the simplicity brought by the method of the invention
Another advantage of the process of the invention is that it lends itself particularly well to the use of fluorinated thermoplastic resin as an insulating material, for example ethylene tetrafluoroethylene (ETFE), fluorethylenepropylene (FEZ) or perfluoroalkoxy fluorocarbon resins (PFA),
The invention therefore also extends to any flat multi-conductor electric cable whose insulating material is a fluorinated thermoplastic resin, or in which the conductors are contained between two tapes of insulating materials which are different in their nature and / or in their color,
