Un tel film présente une mince- épaisseur et est susceptible de recouvrir une surface donnée. Il peut être incorporé dans des éléments, par exemple des murs, des plafonds ou des planchers de locaux.

In the case of a three-phase current according to FIG. 1, there are three supply circuits PI, P2 and P3 and in the case of FIG. 2 there are five supply circuits PI, P2 and P'2, P3 and P'3.
Les figures 1 et 2 présentent un film chauffant composé de trois blocs respectivement Bl, B2 , B3 et Cl, C2, C3. La figure 1 montre un mode de réalisation d'un branchement triphasé en étoile équilibré avec un bloc par phase tandis que la figure 2 illustre un mode de réalisation d'un branchement triphasé en étoile équilibré comportant un bloc alimenté avec les trois phases.  Figures 1 and 2 show a heating film composed of three blocks respectively Bl, B2, B3 and C1, C2, C3. FIG. 1 shows an embodiment of a balanced three-phase star-phase connection with a block per phase whereas FIG. 2 illustrates an embodiment of a balanced three-phase star-shaped connection comprising a block powered with the three phases.
Aux deux figures, pour une meilleure vision des circuits d'alimentation du raccordement 6, ces circuits sont dessinés en gras de même que leur connexion à un élément résistif respectif, ceci tant que ces circuits ne sont pas interrompus.  In both figures, for a better view of the power supply circuits of the connection 6, these circuits are drawn in bold as well as their connection to a respective resistive element, as long as these circuits are not interrupted.
Ces circuits PI, P2, P3, P'2 et P'3 présentent des connexions respectives à un élément résistif 2a, 2b, 2c ou 3a à 3c, 4a à 4c, 5a à 5c qui s' étendent perpendiculairement à la longueur du raccordement 6 et traversent celui-ci plus ou moins profondément selon que le circuit porteur de cette connexion est plus ou moins éloigné par rapport au film 1 chauffant, donc plus ou moins interne ou externe à ce film.  These circuits PI, P2, P3, P'2 and P'3 have respective connections to a resistive element 2a, 2b, 2c or 3a to 3c, 4a to 4c, 5a to 5c which extend perpendicular to the length of the connection 6 and pass through it more or less deeply depending on whether the carrier circuit of this connection is more or less distant from the film 1 heating, so more or less internal or external to this film.
L'élément résistif est avantageusement formé d'au moins une résistance électrique souple en un matériau conducteur recouvert d'un film en matière plastique.  The resistive element is advantageously formed of at least one flexible electrical resistance of a conductive material covered with a plastic film.
Avantageusement, le matériau conducteur est l'aluminium et la matière plastique de recouvrement est un film de polyester. Les figures 1 et 2 vont maintenant être décrites séparément. Advantageously, the conductive material is aluminum and the plastic covering material is a polyester film. Figures 1 and 2 will now be described separately.
A la figure 1, le raccordement électrique 6 est muni de trois circuits PI, P2, P3 d'alimentation électrique à une phase électrique, respectivement les phases 1, 2, 3 mais ceci n'est pas limitatif. Les trois circuits Pl, P2, P3 s'étendent parallèlement dans la longueur du raccordement électrique 6 sur un côté du film chauffant, avantageusement sur un de ses côtés longitudinaux, le circuit Pl étant le plus interne et le circuit P3 étant le plus externe dans ce raccordement 6 par rapport au film 1.  In Figure 1, the electrical connection 6 is provided with three circuits PI, P2, P3 electric power supply to an electrical phase, respectively phases 1, 2, 3 but this is not limiting. The three circuits P1, P2, P3 extend parallel in the length of the electrical connection 6 on one side of the heating film, advantageously on one of its longitudinal sides, the circuit P1 being the innermost and the circuit P3 being the outermost in this connection 6 with respect to the film 1.
Comme le film 1 chauffant de cette figure 1 est composé de trois blocs Bl, B2, B3 comprenant respectivement un élément résistif 2a, 2b, 2c avec une phase par bloc, le bloc Bl est relié au circuit Pl, le bloc B2 est relié au circuit P2 tandis que le bloc B3 est relié au circuit P3.  Since the heating film 1 of this FIG. 1 is composed of three blocks B1, B2, B3 respectively comprising a resistive element 2a, 2b, 2c with a phase per block, the block B1 is connected to the circuit P1, the block B2 is connected to the circuit P2 while the block B3 is connected to the circuit P3.
Le but de la présente invention est de rendre le raccordement 6 le moins épais possible en le laissant avantageusement en deux dimensions.  The purpose of the present invention is to make the connection 6 as light as possible by leaving it advantageously in two dimensions.
Selon l'invention, les circuits d'alimentation Pl, P2, P3 s'étendent parallèlement les uns à côté des autres le long d'au moins un côté du film chauffant comme précédemment mentionné et des moyens 7, 8, 9 sont prévus pour éviter le chevauchement d'au moins un circuit d'alimentation, à la figure 1 Pl puis Pl et P2 par une connexion partant d'un autre circuit, à la figure 1 le circuit P2 pour le circuit Pl, puis le circuit P3 pour les circuits P2 et Pl, cet autre circuit P2 ou P3 alimentant un élément résistif 2b ou 2c respectif.  According to the invention, the supply circuits P1, P2, P3 extend parallel to one another along at least one side of the heating film as previously mentioned and means 7, 8, 9 are provided for avoid the overlap of at least one power supply circuit, in Figure 1 Pl and P1 and P2 by a connection from another circuit, in Figure 1 the circuit P2 for the circuit P1, then the circuit P3 for the circuits P2 and P1, this other circuit P2 or P3 supplying a respective resistive element 2b or 2c.
Selon la présente invention, l'alimentation du film 1 chauffant est en courant triphasé et ne dépasse de l'épaisseur du film chauffant 1. Cela a été rendu possible par la nouvelle disposition des circuits d'alimentation Pl, P2, P3 non superposés mais disposés les uns à côté des autres et l'utilisation de moyens permettant le passage d'une connexion d'un circuit d' alimentation donné à un élément résistif à travers un ou des circuits d'alimentation se trouvant plus proches de l'élément résistif que ledit circuit d'alimentation donné. Cela évite le chevauchement par une ou des connexions de circuits d'alimentation disposés sur son passage vers l'élément résistif, les connexions s' étendant perpendiculairement auxdits circuits d' alimentation . According to the present invention, the supply of the heating film 1 is in three-phase current and does not exceed the thickness of the heating film 1. This has been made possible by the new arrangement of the supply circuits P1, P2, P3 not superposed but arranged next to one another and the use of means allowing the passage of a connection of a given supply circuit to a resistive element through one or more supply circuits located closer to the resistive element than said given supply circuit. This avoids overlap by one or more power circuit connections disposed in its path to the resistive element, the connections extending perpendicular to said power supply circuits.
Avantageusement, les moyens évitant le chevauchement des connexions et des circuits d'alimentation sont sous forme d'au moins une interruption 7, 8, 9 dans au moins un circuit d'alimentation, respectivement à la figure 1 le circuit PI au bloc B2 puis les circuits PI et P2 au bloc B3. Ces interruptions sont avantageusement sous forme de perçages . 7, 8, 9 diminuant ou rendant nulle localement l'épaisseur ' dudit circuit mais ceci n'est pas obligatoire. Il n'est pas nécessaire que le ou les perçages traversent complètement le raccordement du film chauffant 1, seulement qu'ils diminuent localement l'épaisseur dudit raccordement pour permettre le passage de la ou des connexions .  Advantageously, the means avoiding the overlap of the connections and supply circuits are in the form of at least one interruption 7, 8, 9 in at least one supply circuit, respectively in Figure 1 the PI circuit block B2 and then PI and P2 circuits at block B3. These interruptions are advantageously in the form of holes. 7, 8, 9 decreasing or locally voiding the thickness of said circuit but this is not mandatory. It is not necessary that the hole or holes completely through the connection of the heating film 1, only they locally reduce the thickness of said connection to allow the passage of the connection or connections.
Un exemple d'un tel raccordement avec différents circuits PI, P2, P3 va maintenant être plus précisément décrit en regard de la figure 1.  An example of such a connection with different circuits PI, P2, P3 will now be more precisely described with reference to FIG.
A la figure 1, le circuit Pl est interrompu après l'alimentation de l'élément résistif 2a du premier bloc Bl. Pour l'alimentation de l'élément résistif 2b du bloc B2, il est avantageusement effectué une interruption 7 dans le circuit Pl permettant le passage de la connexion d'alimentation de l'élément résistif 2b du bloc B2 partant du circuit P2.  In FIG. 1, the circuit P1 is interrupted after the supply of the resistive element 2a of the first block B1. For the supply of the resistive element 2b of the block B2, an interruption 7 in the circuit P1 is advantageously carried out. allowing the passage of the supply connection of the resistive element 2b of the block B2 from the P2 circuit.
Le circuit P2 est interrompu après l'alimentation de l'élément résistif 2b du second bloc B2 et pour l'alimentation de l'élément résistif 2c du bloc B3, il est avantageusement effectué deux perçages 8 et 9 respectivement dans le circuit PI et dans le circuit P2 permettant le passage de la connexion du circuit P3 à l'élément résistif 2c du bloc B3, les circuits PI et P2 étant alors interrompus avec une épaisseur faible ou nulle pour le passage de ladite connexion partant du circuit P3 à travers les circuits Pl et P2. The circuit P2 is interrupted after the supply of the resistive element 2b of the second block B2 and for the supply of the resistive element 2c of the block B3, it is advantageously carried out two holes 8 and 9 respectively in the circuit PI and in the circuit P2 allowing the passage of the connection of the circuit P3 to the resistive element 2c of the block B3, the circuits PI and P2 then being interrupted with a low or zero thickness for the passage of said starting connection of the circuit P3 through the circuits P1 and P2.
La figure 2 va maintenant être détaillée. Cette figure 2 concerne une alimentation avec trois phases par bloc Cl, C2 ou C3.  Figure 2 will now be detailed. This figure 2 relates to a supply with three phases per block C1, C2 or C3.
Ce qui a été mentionné précédemment en regard du mode de réalisation de la figure 1 est aussi valable pour le mode de réalisation de la figure 2, à savoir qu'au moins une partie des circuits d'alimentation P2, P3, P'2, P'3 s'étendent parallèlement le long d'au moins un côté du film 1 chauffant, des moyens 11 à 19 étant prévus pour éviter le chevauchement d'au moins un circuit, d'alimentation par une connexion partant d'un autre circuit P2, P3, P'2 alimentant un élément résistif respectif. What has been mentioned previously with regard to the embodiment of FIG. 1 is also valid for the embodiment of FIG. 2, namely that at least a part of the supply circuits P2, P3, P'2, P'3 extend parallel along at least one side of the film one heating means 11-19 are provided to avoid duplication of at least one circuit power by a connection starting from another circuit P2, P3, P'2 supplying a respective resistive element.
Le raccordement, pris dans un sens large, dans le cas de la figure 2 comprend cinq circuits Pl, P2 et P'2, P3 et P' 3 pour permettre une alimentation en trois phases des trois éléments résistifs 3a, 4a et 5a du bloc Cl, des trois éléments résistifs 3b, 4b et 5b du bloc C2 et des trois éléments résistifs 3c, 4c et 5c du bloc C3.  The connection, taken in a wide direction, in the case of Figure 2 comprises five circuits P1, P2 and P'2, P3 and P '3 to allow a three-phase supply of the three resistive elements 3a, 4a and 5a of the block C1, of the three resistive elements 3b, 4b and 5b of the block C2 and the three resistive elements 3c, 4c and 5c of the block C3.
Le circuit Pl est un circuit d'alimentation particulier étant donné qu'il ne s'étend pas dans la longueur du raccordement 6 et s'arrête après la connexion pour l'alimentation de son élément résistif 3a associé dans le premier bloc Cl.  The circuit P1 is a particular power supply circuit since it does not extend in the length of the connection 6 and stops after the connection for the supply of its associated resistive element 3a in the first block C1.
En fait, le raccordement 6 proprement dit comprend quatre circuits P2 et P'2, P3 et P'3 qui s'étendent parallèlement dans la longueur du raccordement 6 sur un côté du film chauffant 1, avantageusement la longueur de celui-ci. Du circuit le plus interne P2 au film 1 chauffant au circuit le plus externe P'3, leur succession des circuits dans le raccordement 6 à la figure 2 est P2, P3, P'2, P'3, les circuits P2 et P'2 étant relatifs à la phase 2 et les circuits P3 et P' 3 étant relatifs à la phase 3. In fact, the connection 6 itself comprises four circuits P2 and P'2, P3 and P'3 which extend parallel in the length of the connection 6 on one side of the heating film 1, advantageously the length thereof. From the innermost circuit P2 to the heating film 1 to the outermost circuit P'3, their succession of circuits in the connection 6 in FIG. 2 is P2, P3, P'2, P'3, the P2 and P'2 circuits being relative to the phase 2 and the circuits P3 and P '3 being relative to the phase 3.
Les circuits P2 et P'2 respectivement P3 et P'3 des seconde et troisième phases sont doublés, tandis que la première phase présente un unique circuit Pl.  The P2 and P'2 circuits respectively P3 and P'3 of the second and third phases are doubled, while the first phase has a single circuit P1.
Pour le bloc Bl, c'est le circuit PI de la première phase qui alimente le premier élément résistif 3a du bloc Cl. Ce circuit PI ne se prolonge pas plus loin que sa connexion à l'élément résistif 3a correspondant.  For the block B1, it is the circuit PI of the first phase which feeds the first resistive element 3a of the block C1. This circuit P1 does not extend further than its connection to the corresponding resistive element 3a.
Comme l'alimentation en phase 1 du courant doit aussi être possible pour les blocs C2 et C3 suivant le bloc Cl, il est prévu un circuit d'alimentation auxiliaire 10 qui s'étend à l'intérieur du film 1 chauffant en faisant partiellement le tour du bloc Cl puis celui du bloc C2 à l'exception de son côté , comportant le raccordement 6. Ce circuit d'alimentation auxiliaire 10 intérieur au film s'étend ensuite à l'intérieur des blocs C2 et C3 de manière similaire à celle précédemment indiquée. Ce circuit d'alimentation, auxiliaire 10 interne au film relie l'extrémité de l'élément résistif 3a du bloc Cl alimentée par le circuit PI à l'extrémité de l'élément résistif 3b du bloc C2 à alimenter en phase 1 puis cette extrémité de l'élément résistif 3b du bloc C2 à l'extrémité de l'élément résistif 3c du bloc C3 aussi à alimenter en phase 1. Ainsi un élément résistif 3a, 3b, 3c faisant partie respectivement d'un bloc Cl, C2 ou C3 est alimenté en phase 1.  Since the phase 1 supply of the current must also be possible for the blocks C2 and C3 following the block C1, an auxiliary supply circuit 10 is provided which extends inside the heating film 1 while partially turn of the block Cl and that of the block C2 except for its side, having the connection 6. This auxiliary supply circuit 10 inside the film then extends inside the blocks C2 and C3 in a manner similar to that previously indicated. This auxiliary power supply circuit 10 internal to the film connects the end of the resistive element 3a of the block C1 fed by the circuit PI to the end of the resistive element 3b of the block C2 to supply phase 1 and then this end of the resistive element 3b of the block C2 at the end of the resistive element 3c of the block C3 also to supply phase 1. Thus a resistive element 3a, 3b, 3c belonging respectively to a Cl block, C2 or C3 is powered in phase 1.
En ce qui concerne les deux autres éléments résistifs 4a et 5a du bloc Cl, ceux-ci sont respectivement alimentés en phase 2 par le circuit P2 et en phase 3 par le circuit P3. Le passage du courant dans le circuit P2 est ensuite interrompu tandis que le circuit P3 d'alimentation en phase 3 se prolonge sans interruption pour alimenter le bloc C2. Pour laisser passer la connexion du circuit P3 à son élément résistif 5a associé, la partie du circuit P2 non traversée par la phase 2 est munie d'une interruption 11, avantageusement un perçage au moins partiel du circuit P3 n'autorisant plus le passage du courant à travers lui. As regards the other two resistive elements 4a and 5a of the block C1, they are respectively supplied in phase 2 by the circuit P2 and in phase 3 by the circuit P3. The passage of the current in the circuit P2 is then interrupted while the phase supply circuit P3 3 continues without interruption to supply the block C2. To pass the connection of the circuit P3 to its associated resistive element 5a, the portion of the circuit P2 not traversed by the phase 2 is provided with an interruption 11, advantageously at least a partial piercing of the circuit P3 no longer allowing the passage of the running through him.
Pour le second bloc C2 du film 1 chauffant, celui- ci présente aussi trois éléments résistifs 3b, 4b et 5b. Le premier élément résistif 3b est alimenté électriquement en phase 1 par le circuit d'alimentation auxiliaire 10 interne au film s' étendant entre les blocs Cl et C2.  For the second block C2 of the film 1 heating, it also has three resistive elements 3b, 4b and 5b. The first resistive element 3b is electrically supplied in phase 1 by the auxiliary power supply circuit 10 internal to the film extending between the blocks C1 and C2.
Le second élément résistif 4b est alimenté électriquement en phase 3 par le circuit P3 du raccordement 6, une connexion de ce circuit P3 à l'élément résistif 4b passant à travers le circuit P2 interrompu et qui a été percé par une interruption 12.  The second resistive element 4b is electrically powered in phase 3 by the circuit P3 of the connection 6, a connection of this circuit P3 to the resistive element 4b passing through the interrupted circuit P2 and which has been pierced by an interruption 12.
Le passage du courant dans le circuit P3 est ensuite interrompu dans le raccordement 6, ce circuit étant muni d'une interruption 13 dans la partie du raccordement 6 adjacente au bloc C2 pour permettre l'alimentation électrique de l'élément résistif 5b du bloc C2 par la phase 2, ceci par l'intermédiaire d'une connexion électrique partant du second circuit P'2 d'alimentation en phase 2. Le circuit P2 est également muni d'une interruption 14 pour le passage de la connexion partant du circuit P'2. Le troisième circuit P' 2 du raccordement 6 alimente donc le troisième élément résistif 5b.  The passage of the current in the circuit P3 is then interrupted in the connection 6, this circuit being provided with an interruption 13 in the part of the connection 6 adjacent to the block C2 to allow the electrical supply of the resistive element 5b of the block C2 by the phase 2, this through an electrical connection from the second phase supply circuit P'2 2. The circuit P2 is also provided with an interruption 14 for the passage of the connection from the circuit P '2. The third circuit P '2 of the connection 6 thus supplies the third resistive element 5b.
Pour le troisième bloc C3 du film chauffant 1, celui-ci présente aussi trois éléments résistifs 3c, 4c et 5c. Le premier élément résistif 3c est alimenté électriquement en phase 1 par le circuit d'alimentation auxiliaire 10 interne au film 1 chauffant et s' étendant entre les blocs Cl et C2 puis entre les blocs C2 et C3.  For the third block C3 of the heating film 1, it also has three resistive elements 3c, 4c and 5c. The first resistive element 3c is electrically supplied in phase 1 by the auxiliary supply circuit 10 inside the heating film 1 and extending between the blocks C1 and C2 and between the blocks C2 and C3.
Le second élément résistif 4c est alimenté électriquement en phase 2 par le circuit P'2 du raccordement 6, la connexion de ce circuit P'2 au second élément résistif 4c passant à travers les circuits P2 et P3 interrompus comme précédemment mentionné et qui ont été munis localement d'une interruption respective 16 et 15 pour le passaqe de ladite connexion du circuit P' 2 vers le bloc C3. The second resistive element 4c is electrically powered in phase 2 by the circuit P'2 of the connection 6, the connection of this circuit P'2 to the second resistive element 4c passing through the circuits P2 and P3 interrupted as previously mentioned and which have been locally provided with a respective interruption 16 and 15 for the passaqe of said circuit connection P '2 to block C3.
Ce circuit P'2 est ensuite interrompu dans le raccordement 6 en étant muni d'une interruption 18 dans la partie du raccordement 6 adjacente au bloc C3 pour permettre l'alimentation électrique du bloc C3 en phase 3 par l'intermédiaire du quatrième circuit P' 3 d'alimentation en phase 3. Le quatrième circuit P' 3 en phase 3 alimente le troisième élément résistif 5c par sa connexion traversant le circuit P'2 ainsi que les circuits P2 et P3 également munis d'une interruption, respectivement 19 et 17.  This circuit P'2 is then interrupted in the connection 6 by being provided with an interruption 18 in the part of the connection 6 adjacent to the block C3 to enable the supply of the block C3 in phase 3 via the fourth circuit P The fourth circuit P '3 in phase 3 feeds the third resistive element 5c through its connection through the circuit P'2 as well as the circuits P2 and P3 also provided with an interruption, respectively 19 and 17.
La figure 3 montre un mode de réalisation de l'alimentation électrique en triphasé d'un film chauffant 1. A cette figure, le raccordement électrique principal du film chauffant 1 se trouve sur le côté supérieur du panneau sur sa droite. Conformément à l'invention, les différents raccordements électriques Pcl, Pc2 et Pc3 composant ce raccordement électrique principal et attribués à une phase respective sont disposés parallèlement les uns aux autres et alimentent les circuits respectifs PI, P2 et P3.  Figure 3 shows an embodiment of the three-phase power supply of a heating film 1. In this figure, the main electrical connection of the heating film 1 is on the upper side of the panel on its right. According to the invention, the various electrical connections Pcl, Pc2 and Pc3 composing this main electrical connection and assigned to a respective phase are arranged parallel to each other and feed the respective circuits PI, P2 and P3.
Pour éviter le chevauchement des circuits respectifs Pl, P2 et P3, il est prévu des moyens, ces moyens incluant des connexions respectives dans chaque circuit Pl, P2 et P3 ainsi qu'une disposition spécifique desdits circuits permettant d'éviter ce chevauchement.  To avoid overlapping of the respective circuits P1, P2 and P3, means are provided, these means including respective connections in each circuit P1, P2 and P3 and a specific arrangement of said circuits to avoid this overlap.
A la figure 3, il est à noter que les circuits Pl, P2 et P3 sont dessinés exagérément espacés les uns des autres et que le rapport entre leurs longueurs respectives a aussi été fortement agrandi.  In Figure 3, it should be noted that the circuits P1, P2 and P3 are drawn excessively spaced from each other and that the ratio between their respective lengths has also been greatly enlarged.
Dans le mode de réalisation montré à la figure 3, ce mode étant susceptible de modifications tant que celles-ci contribuent à empêcher le chevauchement des circuits PI, P2 et P3, ces modifications pouvant concerner notamment une autre disposition des phases l'une ou les unes par rapport aux autres, la première partie du circuit P3 s'étend sur une plus longue longueur du film chauffant 1 que la première partie du circuit P2 et la première partie du circuit P2 s'étend aussi sur une plus longue longueur du film chauffant 1 que la première partie du circuit Pl. In the embodiment shown in FIG. 3, this mode being able to be modified as long as these contribute to preventing the overlap of the circuits PI, P2 and P3, these modifications being able to concern in particular another arrangement of the phases one or the ones with respect to the others, the first part of the circuit P3 extends over a longer length of the heating film 1 that the first part of the circuit P2 and the first part of the circuit P2 also extends over a longer length of the heating film 1 than the first part of the circuit P1.
A la fin de la première partie d'un circuit PI, P2 ou P3, cette première partie est reliée à une seconde partie du circuit respectif PI, P2 ou P3 s' étendant dans la direction opposée à la première partie pour se diriger vers le côté du film 1 portant le raccordement électrique principal du film chauffant 1. La liaison entre chaque première partie et leur seconde partie associée se fait par un raccord respectif 21, 22, 23.  At the end of the first part of a circuit PI, P2 or P3, this first part is connected to a second part of the respective circuit PI, P2 or P3 extending in the opposite direction to the first part to go towards the side of the film 1 carrying the main electrical connection of the heating film 1. The connection between each first part and their associated second part is via a respective connector 21, 22, 23.
Séquentiellement, en partant du bord du film chauffant présentant le raccordement principal et par rapport auquel les parties consécutives des circuits Pl, P2 et P3 s'étendent parallèlement et en descendant vers la portion médiane du film chauffant 1, la disposition des circuits Pl, P2 et P3 comprend à la figure 3 la première partie du circuit P3, la première partie du circuit P2 et la première partie du circuit Pl. Ensuite cette première partie du circuit Pl est suivie par la seconde partie dudit même circuit Pl, puis par la seconde partie du circuit P2 et la seconde partie du circuit P3, ceci pour éviter les chevauchements d'un ou de circuits par un ou des autres circuits Pl, P2 et P3.  Sequentially, starting from the edge of the heating film having the main connection and with respect to which the consecutive portions of the circuits P1, P2 and P3 extend parallel and down to the middle portion of the heating film 1, the arrangement of the circuits P1, P2 and P3 comprises in FIG. 3 the first part of the circuit P3, the first part of the circuit P2 and the first part of the circuit P1. Then this first part of the circuit P1 is followed by the second part of the same circuit P1, then by the second part of the circuit P2 and the second part of the circuit P3, this to avoid overlapping of one or circuits by one or the other circuits P1, P2 and P3.
Du fait, premièrement, de la différence entre les longueurs de la première partie respective des circuits Pl, P2 et P3, il n'y a pas chevauchement desdits circuits Pl, P2 et P3. Ceci est aussi obtenu, secondement, par la disposition des secondes parties des circuits Pl, P2 ou P3 les unes par rapport aux autres. En effet, comme déjà mentionné, la seconde partie du circuit Pl est placée juste après la première partie du circuit PI et reliée à celle-ci par le raccord 21. Comme la première partie du circuit PI est la plus courte des premières parties des circuits Pl, P2 et P3, il ne peut y avoir chevauchement d'un circuit P2 ou P3 par la seconde partie du circuit Pl. First, because of the difference between the lengths of the respective first part of the circuits P1, P2 and P3, there is no overlap of said circuits P1, P2 and P3. This is also obtained, secondly, by the arrangement of the second parts of the circuits P1, P2 or P3 relative to each other. Indeed, as already mentioned, the second part of the circuit Pl is placed just after the first part of the circuit PI and connected thereto by the connector 21. As the first part of the circuit PI is the shortest of the first parts of the circuits P1, P2 and P3, there can be no overlap of a P2 or P3 circuit by the second part of the circuit Pl.
Il en va de même pour la seconde partie du circuit P2 qui ne chevauche pas le circuit P3 en étant dirigée vers le raccordement électrique principal du film chauffant 1.  The same goes for the second part of the circuit P2 which does not overlap the circuit P3 while being directed towards the main electrical connection of the heating film 1.
Similairement aux premières parties, les secondes parties s'étendent dans la direction du raccordement principal du film chauffant 1 avec des longueurs différentes, la seconde partie du circuit Pl s' étendant plus vers le bord droit du film chauffant que la seconde partie du circuit P2, elle-même s' étendant plus vers le bord droit du film chauffant que la seconde partie du circuit P3.  Similarly to the first parts, the second parts extend in the direction of the main connection of the heating film 1 with different lengths, the second part of the circuit P extending more towards the right edge of the heating film than the second part of the circuit P2 itself extending more towards the right edge of the heating film than the second part of the circuit P3.
Ces secondes parties sont respectivement reliées aux troisièmes parties correspondantes du circuit Pl, P2 ou P3 par un raccord respectif 31, 32, 33.  These second parts are respectively connected to the corresponding third parts of the circuit P1, P2 or P3 by a respective connection 31, 32, 33.
Il en va de même pour les parties successives des circuits Pl, P2 et P3. Ainsi, le chevauchement d'au moins un circuit Pl, P2 ou P3 par au moins un autre circuit Pl, P2 ou P3 est évité pour toutes les parties desdits circuits Pl, P2 et P3.  The same goes for the successive parts of the circuits P1, P2 and P3. Thus, the overlap of at least one circuit P1, P2 or P3 by at least one other circuit P1, P2 or P3 is avoided for all the parts of said circuits P1, P2 and P3.
A la figure 3, seules les trois premières parties des circuits Pl, P2 et P3 ont été entièrement représentées, les quatrièmes l'étant seulement partiellement tandis que les autres parties desdits circuits Pl, P2 et P3 n'ont pas été représentées.  In Figure 3, only the first three parts of the circuits P1, P2 and P3 have been fully represented, the fourth being only partially while the other parts of said circuits P1, P2 and P3 have not been shown.
Les avantages de la présente invention sont, en plus de garantir une alimentation en triphasé d'un film chauffant avec un raccordement électrique ne dépassant pas de l'épaisseur du film, de permettre un équilibrage de l'alimentation triphasée, un gain de fil par rapport à trois films monophasés, un gain de place, un point milieu interne et la possibilité d' avoir soit trois phases imbriquées dans un bloc ou trois phases par bloc. The advantages of the present invention are, in addition to guaranteeing a three-phase supply of a heating film with an electrical connection not exceeding the thickness of the film, to allow a balancing of the three-phase power supply, a gain of wire by compared to three single-phase films, space saving, a midpoint internal and the possibility of having either three nested phases in one block or three phases per block.
