DE FABRICATION D'UN PANNEAU DE VITRAGE  FOR MANUFACTURING A GLAZING PANEL
1. Domaine de l'invention 1. Field of the invention
Le domaine de l'invention est celui des panneaux de vitrage comprenant des feuilles de verre délimitant des espaces internes. L'invention concerne notamment un tel panneau comprenant au moins un composant prévu pour être alimenté au moyen d'un signal électrique ou électronique. The field of the invention is that of glazing panels comprising glass sheets delimiting internal spaces. The invention particularly relates to such a panel comprising at least one component intended to be powered by means of an electrical or electronic signal.
Ces panneaux peuvent être utilisés dans tout type d'applications tels que les vitrages utilitaires, les vitrages pour véhicules ou pour bâtiments. These panels can be used in all types of applications such as utility glazing, glazing for vehicles or buildings.
2. Solutions de l'art antérieur 2. Solutions of the prior art
Un panneau de vitrage concerné par l'invention est par exemple un panneau de vitrage isolant (ou "Insulating glass units" en anglais). A glazing panel concerned by the invention is for example an insulating glass panel (or "Insulating glass units" in English).
Un tel panneau de vitrage isolant comprend de manière classique une première et une seconde feuille de verre associées ensemble par l'intermédiaire d'un cadre intercalaire qui les maintient parallèles à une certaine distance l'une de l'autre. Le panneau est refermé en sa périphérie grâce à un joint périphérique de sorte que l'espace entre les feuilles de verre, également appelé espace interne est complètement fermé. Such an insulating glazing panel conventionally comprises a first and a second glass sheet associated together via a spacer frame which holds them parallel at a distance from one another. The panel is closed at its periphery through a peripheral seal so that the space between the glass sheets, also called internal space is completely closed.
L'espace interne peut être vidé de tout gaz, on parle alors de vitrage sous vide. Le transfert d'énergie à travers un panneau de vitrage isolant sous vide est grandement réduit par l'espace de vide. L'espace interne peut également emprisonner une lame de gaz, de l'air sec traditionnellement. Le transfert d'énergie à travers un panneau isolant selon cette structure classique est réduit, du fait de la présence de la lame d'air dans l'espace interne par rapport à une simple feuille de verre. Le transfert d'énergie peut encore être réduit en augmentant l'épaisseur de l'espace interne pour augmenter l'isolation produite par la lame d'air. Il y a cependant une valeur limite de l'épaisseur de l'espace interne à partir de laquelle la convection dans la lame d'air entre les feuilles de verre fait augmenter le transfert d'énergie. The internal space can be emptied of any gas, it is called vacuum glazing. Energy transfer through a vacuum insulating glazing panel is greatly reduced by the vacuum space. The internal space can also trap a gas blade, traditionally dry air. The energy transfer through an insulating panel according to this conventional structure is reduced, because of the presence of the air gap in the inner space with respect to a single sheet of glass. Energy transfer can be further reduced by increasing the thickness of the internal space to increase the insulation produced by the air gap. There is, however, a limit value of the thickness of the internal space from which convection in the air gap between the glass sheets increases the energy transfer.
Le transfert d'énergie peut encore être réduit en ajoutant des couches supplémentaires sous la forme d'espaces internes additionnels entourés par des feuilles de verre additionnelles. Par exemple, trois feuilles de verre parallèles séparées par deux espaces internes et scellées en leurs périphéries grâce à un joint. De cette manière, les épaisseurs des espaces internes peuvent être maintenues en dessous de la limite maximale imposée par les effets de convection dans les lames d'air et ainsi le transfert d'énergie peut être encore réduit. Energy transfer can be further reduced by adding additional layers in the form of additional internal spaces surrounded by additional glass sheets. For example, three parallel glass sheets separated by two internal spaces and sealed at their periphery through a seal. In this way, the thicknesses of the internal spaces can be kept below the maximum limit imposed by the convection effects in the air knives and thus the energy transfer can be further reduced.
Par ailleurs, le transfert d'énergie peut également être réduit en substituant l'air (N2, 02) par un gaz plus dense et moins conducteur thermique. Des gaz adéquats doivent être incolores, non toxiques pour l'homme (au moins en deçà de concentrations raisonnables), non corrosifs, non inflammables, insensibles à l'exposition aux radiations ultraviolettes, plus dense que l'air et présentant une conductivité thermique plus faible. L'argon (Ar), le krypton (Kr), le xénon (Xe) et l'héxafluorure de soufre (SF6) sont des exemples de tels gaz qui sont communément substitués à l'air dans les panneaux de vitrage isolants, μ Moreover, the energy transfer can also be reduced by replacing the air (N 2 , O 2 ) with a gas that is denser and less thermally conductive. Adequate gases must be colorless, non-toxic to humans (at least below reasonable levels), non-corrosive, non-flammable, insensitive to exposure to ultraviolet radiation, denser than air and have a higher thermal conductivity. low. Argon (Ar), krypton (Kr), xenon (Xe) and sulfur hexafluoride (SF 6 ) are examples of such gases that are commonly substituted for air in insulating glazing panels, μ
On connaît également (par exemple de EPI 840449) des panneaux de verre intégrant des composants électroniques, tels que des diodes électroluminescentes (ou LED pour « Light Emitting Diode »), par exemple pour afficher de l'information ou pour des applications dans l'éclairage. Dans le cadre de ces applications, la fabrication d'un panneau de vitrage intégrant des composants électroniques comprend typiquement une étape de dépôt d'une couche conductrice transparente sur la première feuille de verre, une étape de réalisation des pistes conductrices du circuit conducteur interne à partir de la couche conductrice transparente et une étape de dépôt et solidarisation (par exemple au moyen d'une colle conductrice) des composants électroniques sur les pistes conductrices du circuit conducteur interne. Le panneau de vitrage est obtenu par application de la seconde feuille de verre sur le cadre intercalaire, l'ensemble étant refermé en sa périphérie grâce à un joint périphérique de sorte que l'espace interne entre les feuilles de verre est complètement fermé. Also known (for example from EPI 840449) are glass panels incorporating electronic components, such as light emitting diodes (or LEDs for "Light Emitting Diode"), for example for displaying information or for applications in the field. lighting. In the context of these applications, the manufacture of a glazing panel incorporating electronic components typically comprises a step of depositing a transparent conductive layer on the first glass sheet, a step of producing the conductive tracks of the internal conductive circuit. from the transparent conductive layer and a step of depositing and joining (by example by means of a conductive glue) electronic components on the conductive tracks of the internal conductive circuit. The glazing panel is obtained by applying the second glass sheet to the spacer frame, the assembly being closed at its periphery by a peripheral seal so that the internal space between the glass sheets is completely closed.
Dans le cas de ce panneau à LEDs, pour connecter le circuit conducteur interne à un circuit électrique externe (on entend par là externe au panneau de verre) tel qu'une alimentation électrique externe, il est nécessaire d'intégrer, avant la fermeture du panneau, un élément conducteur électrique, par exemple un fil électrique, dont une extrémité est connectée électriquement à l'intérieur du panneau de vitrage et l'autre extrémité s'étend au-delà des bords du panneau. In the case of this LED panel, to connect the internal conductor circuit to an external electrical circuit (here we mean external to the glass panel) such as an external power supply, it is necessary to integrate, before closing the panel, an electrical conductive element, for example an electrical wire, one end of which is electrically connected to the inside of the glazing panel and the other end extending beyond the edges of the panel.
Le document EP I 529922 illustre d'un tel élément conducteur électrique sous la forme d'un connecteur dans un panneau de double vitrage. Le connecteur permet d'amener des signaux électriques depuis l'extérieur vers l'intérieur du panneau de double vitrage via l'intercalaire. Tel qu'illustré notamment par la figure 1 de ce document, ce connecteur consiste en une pièce de coin qui est prévu pour être interconnecté entre deux branches du cadre intercalaire 3 du double vitrage. EP I 529922 illustrates such an electrically conductive element in the form of a connector in a double glazing panel. The connector allows electrical signals to be supplied from the outside to the inside of the double glazing panel via the spacer. As illustrated in particular in Figure 1 of this document, this connector consists of a corner piece which is intended to be interconnected between two branches of the intermediate frame 3 of the double glazing.
Ce type de connecteur sous la forme d'une pièce moulée prévu pour s'insérer dans deux branches d'un cadre intercalaire est spécialement conçu pour un cadre intercalaire donné et ne peut donc s'adapter à d'autres cadres intercalaires présentant par exemple des dimensions différentes. Or, le marché des panneaux de double vitrage est tel que l'espace entre les première et seconde feuilles de verres est généralement variable entre 6 et 27mm suivant la demande du client. De même, il existe différentes coupes et dimensions de cadres intercalaires suivant le pays de vente ou l'application. Cela implique donc de faire un moule de pièce pour chaque type d'intercalaire et chaque espace de panneau de double vitrage afin de pouvoir fournir une gamme large de produit incluant cette pièce. This type of connector in the form of a molded part intended to fit into two branches of a spacer frame is specially designed for a given spacer frame and therefore can not adapt to other intermediate frames having for example different dimensions. However, the market for double glazing panels is such that the space between the first and second sheets of glass is generally variable between 6 and 27mm depending on the customer's request. Similarly, there are different cuts and sizes of infill frames depending on the country of sale or application. So this involves making a room mold for each type of interlayer and each panel space double glazing in order to provide a wide range of products including this piece.
En outre, un tel connecteur est généralement conçu pour s'insérer dans une zone périphérique déterminée du vitrage et ne laisse pas beaucoup de liberté de placement de la pièce dans le vitrage. In addition, such a connector is generally designed to fit into a given peripheral zone of the glazing and does not allow much freedom of placement of the piece in the glazing.

4. Exposé de l'invention Conformément à un mode de réalisation particulier, l'invention concerne un panneau de vitrage, en particulier panneau de vitrage isolant, comprenant au moins une première et une seconde feuilles de verre associées ensemble par l'intermédiaire d'un cadre intercalaire qui les maintient à une certaine distance l'une de l'autre et, entre lesdites au moins deux feuilles de verre, au moins un espace interne comprenant une lame d'un gaz isolant fermé par le cadre intercalaire disposé autour dudit espace interne. 4. DESCRIPTION OF THE INVENTION In accordance with a particular embodiment, the invention relates to a glazing panel, in particular an insulating glazing panel, comprising at least a first and a second glass sheet associated together via an intermediate frame which keeps them at a distance from each other and, between said at least two sheets of glass, at least one internal space comprising a blade of an insulating gas closed by the spacer frame disposed around said space internal.
Selon l'invention, dans un tel panneau de vitrage, le cadre intercalaire comprend une ouverture faisant communiquer l'espace interne avec l'extérieur du panneau. Selon l'invention encore, le panneau comprend au moins un élément conducteur électrique inséré dans l'ouverture, une première extrémité de l'élément conducteur étant située dans l'espace interne et une seconde extrémité de l'élément conducteur étant situé à l'extérieur de l'espace interne According to the invention, in such a glazing panel, the spacer frame comprises an opening communicating the internal space with the outside of the panel. According to the invention, the panel comprises at least one electrically conductive element inserted in the opening, a first end of the conductive element being located in the internal space and a second end of the conductive element being located at the outside the inner space
Selon l'invention encore, le panneau comprend également un premier bouchon de matériau élastomère thermoplastique fermant l'ouverture autour de l'élément conducteur électrique. According to the invention, the panel also comprises a first plug of thermoplastic elastomer material closing the opening around the electrically conductive element.
Le principe général de l'invention repose sur la création dans le cadre intercalaire existant d'un panneau de vitrage classique d'une ouverture faisant communiquer l'espace interne avec l'extérieur du panneau qui permet l'insertion d'élément(s) conducteur(s) assurant la connexion électrique depuis l'extérieur vers l'intérieur d'un panneau. Le premier bouchon de matériau élastomère thermoplastique assure l'étanchéité et permet donc, dans le cas d'un panneau de vitrage isolant, de préserver les éventuelles bonnes propriétés d'isolation thermique du panneau. The general principle of the invention is based on the creation in the existing spacer frame of a conventional glazing panel of an opening communicating the internal space with the outside of the panel which allows the insertion of element (s) conductor (s) providing the electrical connection from the outside to the inside of a panel. The first plug of thermoplastic elastomer material ensures the seal and therefore allows, in the case of a insulating glass panel, to preserve the possible good thermal insulation properties of the panel.
Ainsi, du fait que le trou peut être réalisé dans tout type de cadre intercalaire, une telle technique de connexion peut s'adapter à tout type de panneau de vitrage multiple à cadre intercalaire. En outre, une telle technique ne nécessite pas la conception d'une pièce spécifiquement adaptée aux dimensions du panneau et notamment aux dimensions d'un intercalaire séparant les deux feuilles de verre. Thus, because the hole can be made in any type of spacer frame, such a connection technique can be adapted to any type of multi-glazed glazing panel. In addition, such a technique does not require the design of a part specifically adapted to the dimensions of the panel and in particular to the dimensions of an interlayer separating the two sheets of glass.
Par ailleurs, du fait que le trou peut être réalisé à tout endroit du cadre intercalaire, une telle technique de connexion selon l'invention autorise une importante liberté de positionnement de la connexion électrique dans le panneau et/ou permet d'assurer autant de connexions électrique depuis l'extérieur vers l'intérieur du panneau que nécessaire. Furthermore, because the hole can be made at any location of the spacer frame, such a connection technique according to the invention allows a large freedom of positioning of the electrical connection in the panel and / or ensures as many connections electrical from the outside to the inside of the panel as needed.
En outre, par rapport aux techniques classiques mettant en œuvre des connecteurs conçus spécifiquement tel que décrit dans le document EPI 529922, la technique de connexion selon l'invention est simple est peu coûteuse. In addition, compared with conventional techniques using specifically designed connectors as described in EPI 529922, the connection technique according to the invention is simple and inexpensive.

For example, the sheath is a sheath referenced RBK-ILS-125-NR3-0-65MM and marketed by Tyco Electronics.
Ainsi, on obtient une très bonne étanchéité du fait que la combinaison de ces trois matériaux de la gaine présente une excellente adhésion avec le polyiso butylène du premier bouchon. Thus, a very good seal is obtained because the combination of these three materials of the sheath has excellent adhesion with the polyisobutylene of the first plug.
Selon un mode de réalisation avantageux de l'invention, la première extrémité du câble électrique est enrobée dans un second bouchon de matériau élastomère thermoplastique.

6. Description d'un mode de réalisation de l'invention 6. Description of an embodiment of the invention
On présente, en relation avec les figures 1 et 2, une vue en coupe d'une portion d'un panneau de vitrage 100 selon un mode de réalisation de l'invention. Le panneau de vitrage 100 est un panneau de double vitrage comprenant une première et une seconde feuilles de verre 10, 11 (par exemple des feuilles de verre sodo-silico-calcique de 4 mm d'épaisseur) associées ensemble par l'intermédiaire d'un cadre intercalaire 12 qui les maintient à une certaine distance l'une de l'autre. Entre les deux feuilles de verre 10, 11, se trouve un espace interneWith reference to FIGS. 1 and 2, a sectional view of a portion of a glazing panel 100 according to one embodiment of the invention is presented. The glazing panel 100 is a double glazing panel comprising a first and a second glass sheet 10, 11 (for example 4 mm thick soda-silico-calcium glass sheets) associated together via an intermediate frame 12 which keeps them at a distance from one another. Between the two sheets of glass 10, 11, there is an internal space
15 comprenant une lame d'un gaz isolant et fermé par le cadre intercalaire disposé autour de l'espace interne. Préférentiellement, un joint périphérique 13 assure l'étanchéité entre l'espace interne et l'extérieur. 15 comprising a blade of an insulating gas and closed by the spacer frame disposed around the internal space. Preferably, a peripheral seal 13 seals between the internal space and the outside.
Le cadre intercalaire 12 (également appelé espaceur) s'étend en périphérie des feuilles de verre et est par exemple constitué d'acier galvanisé de 0,4 mm d'épaisseur. Le cadre intercalaire 12 comprend une section creuse transversale qui a, par exemple, la forme d'un carré. Par exemple, une tablette de matière dessicative (non représentée sur les figures) est disposée à l'intérieur du cadre intercalaire 12. Le joint périphérique 13 comprend des couches d'étanchéité de polyisobutylène 13 disposées respectivement entre le cadre intercalaire 12 et chacune des première et seconde feuilles de verre 10, 11. Par exemple, le polyisobutylène utilisé a une perméabilité d'environ 0, 1 1 g d'eau par mm d'épaisseur par m2 x 24 h x kPa de vapeur d'eau. Avantageusement, le joint périphérique 13 comprend également un cordon de polysulfure ou de résine silicone disposé en contact avec les couches d'étanchéité 13 entre chacune des feuilles 10, 11 et le cadre intercalaire 12. On peut également mettre en œuvre un joint périphérique plus étanche encore, par exemple à base de soudure de verre. The spacer frame 12 (also called spacer) extends at the periphery of the glass sheets and is for example made of galvanized steel 0.4 mm thick. The spacer frame 12 comprises a transverse hollow section which has, for example, the shape of a square. For example, a tablet desiccant material (not shown in the figures) is disposed inside the spacer frame 12. The peripheral seal 13 comprises polyisobutylene sealing layers 13 disposed respectively between the spacer frame 12 and each of the first and second sheets of glass 10, 11. For example, the polyisobutylene used at a permeability of about 0.11 g of water per mm of thickness per m 2 x 24 hx kPa of water vapor. Advantageously, the peripheral seal 13 also comprises a bead of polysulfide or silicone resin disposed in contact with the sealing layers 13 between each of the sheets 10, 11 and the spacer frame 12. It is also possible to implement a leaktight peripheral seal still, for example based on glass solder.
Par exemple, le panneau de double vitrage 100 comprend en outre un revêtement 16, par exemple une couche réfléchissant les rayonnements infrarouges, par exemple, une couche « Stopsol Super Silver » commercialisée par la société AGC Glass Europe. For example, the double glazing panel 100 further comprises a coating 16, for example a layer reflecting infrared radiation, for example, a layer "Stopsol Super Silver" marketed by AGC Glass Europe.
Bien entendu, le revêtement peut également être situé par exemple sur toute la surface interne de la seconde feuille de verre 11 , ou seulement sur une partie de la face interne de l'une des feuilles de verre 10, 11. Of course, the coating may also be located for example on the entire inner surface of the second glass sheet 11, or only on a portion of the inner face of one of the glass sheets 10, 11.
Par exemple, l'espace interne 15 comprend une lame de gaz isolant comprenant par exemple un mélange 90 % d'argon et 10% Air sec en volume. For example, the internal space 15 comprises an insulating gas blade comprising for example a mixture of 90% argon and 10% dry air by volume.
Préférentiellement, la lame de gaz isolant est comprise entre 10 et 15mm. Par exemple, dans la suite, la lame de gaz fait 11 mm d'épaisseur. Preferably, the insulating gas blade is between 10 and 15 mm. For example, in the following, the gas blade is 11 mm thick.
Le cadre intercalaire 12 comprend une ouverture 122 faisant communiquer l'espace interne 15 avec l'extérieur du panneau. Le panneau comprend au moins un élément conducteur électrique 14 inséré dans l'ouverture 122, une première extrémité 141 de l'élément conducteur étant située dans l'espace interne et une seconde extrémité 142 de l'élément conducteur étant situé à l'extérieur de l'espace interne 15. The spacer frame 12 includes an opening 122 communicating the internal space 15 with the outside of the panel. The panel comprises at least one electrically conductive element 14 inserted in the opening 122, a first end 141 of the conductive element being located in the internal space and a second end 142 of the conductive element being located outside the the internal space 15.
L'ouverture peut être réalisée en toute position sur le cadre intercalaire (au niveau d'une longueur du vitrage, au niveau d'une largeur du vitrage ou même au niveau d'un coin). La figure 2 représente une portion du cadre intercalaire 12 ayant été foré de part et d'autre pour réaliser l'ouverture 122. The opening can be made in any position on the spacer frame (at a length of the glazing, at a width of the glazing or even at a corner). FIG. 2 represents a portion of the spacer frame 12 having been drilled on both sides to make the opening 122.
Le panneau comprend également un premier bouchon 17 de matériau élastomère thermoplastique fermant l'ouverture 122 autour de l'élément conducteur électrique 14. Le premier bouchon 17 selon l'invention peut prendre toute forme adéquate pour fermer l'ouverture 122. The panel also comprises a first plug 17 of thermoplastic elastomer material closing the opening 122 around the electrically conductive element 14. The first plug 17 according to the invention can take any form suitable for closing the opening 122.
Préférentiellement, le matériau élastomère thermoplastique est constitué au moins partiellement de caoutchouc synthétique. De manière encore plus préférée, le matériau élastomère thermoplastique est du polyisobutylène. On illustre en relation avec la figure 3, un mode de réalisation particulier du panneau de vitrage selon l'invention selon lequel l'élément conducteur électrique est un câble électrique 14 comprenant au moins un élément conducteur longiligne, par exemple trois fils métalliques conducteur, protégés par une gaine isolante 143. Bien entendu un nombre quelconque d'éléments conducteurs longilignes peut être mis en œuvre, par exemple un nombre compris entre 1 et 10, voir même un plus grand nombre. Preferably, the thermoplastic elastomer material consists at least partially of synthetic rubber. Even more preferably, the thermoplastic elastomer material is polyisobutylene. FIG. 3 illustrates a particular embodiment of the glazing panel according to the invention according to which the electrically conductive element is an electric cable comprising at least one elongated conductive element, for example three conductive, protected wires. by an insulating sheath 143. Of course, any number of elongated conductive elements can be implemented, for example a number between 1 and 10, or even a larger number.
Préférentiellement, le diamètre du câble électrique n' est pas supérieur à 60% de l'épaisseur (séparant les deux feuilles de verre 10, 1 1) du cadre intercalaire. Preferably, the diameter of the electric cable is not greater than 60% of the thickness (separating the two glass sheets 10, 1 1) from the spacer frame.
Par exemple, la gaine isolante 143 est constituée au moins en partie de polyéthylène basse densité (aussi désigné par l'acronyme PEBD et défini en ce que sa densité avoisine la valeur de 0,92), de polyéthylène haute densité (également désigné par l'acronyme PEHD et défini en ce que sa densité avoisine la valeur de 0,95) et de polyamide. Par exemple, la gaine est une gaine référencée RBK-ILS-125-NR3-0-65MM et commercialisée par la société Tyco Electronics. Par ailleurs, selon un mode de réalisation préférentiel de l'invention, dans l'espace interne 15 du panneau 100 est logé au moins un substrat isolant 18, par exemple un substrat isolant qui est revêtu, au moins partiellement, d'au moins une piste conductrice reliée électriquement avec la première extrémité 141 du câble électrique. Avantageusement, le substrat isolant 18 revêtu, au moins partiellement, d'au moins une piste conductrice est une carte de circuit imprimée 18 qui est relié électriquement avec la première extrémité 141 du câble électrique. For example, the insulating sheath 143 is formed at least in part of low density polyethylene (also referred to by the acronym LDPE and defined in that its density is close to 0.92), high density polyethylene (also referred to as acronym HDPE and defined in that its density is close to 0.95) and polyamide. For example, the sheath is a sheath referenced RBK-ILS-125-NR3-0-65MM and marketed by Tyco Electronics. Furthermore, according to a preferred embodiment of the invention, in the internal space 15 of the panel 100 is housed at least one insulating substrate 18, for example an insulating substrate which is coated, at least partially, with at least one conductive track electrically connected with the first end 141 of the electric cable. Advantageously, the insulating substrate 18 coated, at least partially, with at least one conductive track is a printed circuit board 18 which is electrically connected with the first end 141 of the electrical cable.
La première extrémité 141 du câble électrique est enrobée dans un second bouchon 20 de matériau élastomère thermoplastique. Préférentiellement, le matériau élastomère thermoplastique est constitué au moins partiellement de caoutchouc synthétique. De manière encore plus préférée, le matériau élastomère thermoplastique est du polyisobutylène. The first end 141 of the electrical cable is embedded in a second plug 20 of thermoplastic elastomer material. Preferably, the thermoplastic elastomer material consists at least partially of synthetic rubber. Even more preferably, the thermoplastic elastomer material is polyisobutylene.
Le panneau 100 comprend un réservoir 19 solidarisé dans l'espace interne 15 sur le cadre intercalaire 12 de sorte à être positionné en regard avec l'ouverture 122, le réservoir 19 comprenant un trou traversant (non représenté) permettant le passage de la première extrémité 141 du câble électrique 14. The panel 100 comprises a reservoir 19 secured in the internal space 15 on the spacer frame 12 so as to be positioned facing the opening 122, the reservoir 19 comprising a through hole (not shown) allowing the passage of the first end 141 of the electric cable 14.
L'ouverture 122 peut être réalisée par exemple par forage du cadre intercalaire sur toute son épaisseur de sorte à obtenir un trou traversant. Du fait que le cadre intercalaire comprend une section creuse transversale carrée, le forage est préférentiellement réalisé sur la paroi de l'intercalaire 12 du côté intérieur au panneau de vitrage 100 et également sur la paroi de l'intercalaire 12 du côté extérieur au panneau de vitrage 100. The opening 122 may be made for example by drilling the spacer frame over its entire thickness so as to obtain a through hole. Because the spacer frame comprises a square cross-section, the drilling is preferably carried out on the wall of the insert 12 on the inside of the glazing panel 100 and also on the wall of the insert 12 on the outside of the panel. glazing 100.
Préférentiellement, le premier trou dans la paroi du côté intérieur au panneau de vitrage est dimensionné pour accueillir le réservoir 19 et le second trou dans la paroi du côté extérieur au panneau de vitrage est dimensionné pour pouvoir insérer la première extrémité 141 du câble d'alimentation 14 avec un degré d'inclinaison entre le câble 14 et le cadre intercalaire 12, par exemple, compris entre 30 et 90°. Le second trou est foré en décalé par rapport au premier trou afin de pouvoir insérer le câble 14 avec son degré d'inclinaison tout en plaçant l'extrémité du câble 14 dans le fond du réservoir 19 le plus proche de sa face arrière. Preferably, the first hole in the wall on the inner side of the glazing panel is sized to receive the reservoir 19 and the second hole in the wall of the outer side of the glazing panel is sized to insert the first end 141 of the power cable. 14 with a degree of inclination between the cable 14 and the spacer frame 12, for example, between 30 and 90 °. The second hole is drilled offset from the first hole in order to insert the cable 14 with its degree of inclination while placing the end of the cable 14 in the bottom of the tank 19 closest to its rear face.
Par exemple le réservoir 19 est réalisé en matériau plastique, par exemple en PA6. Préférentiellement, le réservoir 19 est de forme rectangulaire et prévoit un petit renfoncement à sa base pour pouvoir s'insérer dans le cadre intercalaire 12 foré. Une alternative au mode de réalisation de ce réservoir 19 est de concevoir un réservoir formé par deux coques s'emboitant l'une dans l'autre afin de faciliter l'insertion du circuit imprimé 18 relié au câble 14 dans ce réservoir 19. For example the reservoir 19 is made of plastic material, for example PA6. Preferably, the reservoir 19 is of rectangular shape and provides a small recess at its base to be inserted into the infill 12 interfered frame. An alternative to the embodiment of this reservoir 19 is to design a reservoir formed by two shells interlocking one inside the other to facilitate the insertion of the printed circuit 18 connected to the cable 14 in the reservoir 19.
Dans la phase d'assemblage, le câble 14 et le circuit imprimé 18 sont connectés ensemble dans un premier temps. Le réservoir 19 est positionné sur le cadre intercalaire 12 au-dessus du premier trou. La carte de circuit imprimé 18, reliée au câble 14, est introduite dans une fente 191 prévue dans un coté du réservoir 19 de sorte qu'une portion du circuit imprimé (préférentiellement la portion du circuit comprenant la piste électrique sur laquelle doit être connectée électriquement la première extrémité 141 du câble électrique 14) est localisé dans le réservoir 19. In the assembly phase, the cable 14 and the printed circuit 18 are connected together in a first step. The reservoir 19 is positioned on the spacer frame 12 above the first hole. The printed circuit board 18, connected to the cable 14, is introduced into a slot 191 provided in one side of the reservoir 19 so that a portion of the printed circuit (preferably the portion of the circuit comprising the electrical track on which must be electrically connected the first end 141 of the electric cable 14) is located in the reservoir 19.
Le polyisobutylène du second bouchon 20 est injecté via la face supérieure du réservoir 19 afin de combler l'espace vide dans le réservoir 19. Ce polyisobutylène vient surmouler les composants situés à l'intérieur du réservoir ainsi qu'une partie du câble 14 au dos du cadre intercalaire 12 côté extérieur au panneau de vitrage. The polyisobutylene of the second plug 20 is injected via the upper face of the reservoir 19 in order to fill the empty space in the reservoir 19. This polyisobutylene overmoulds the components located inside the reservoir and a portion of the cable 14 at the back of the spacer frame 12 on the outside of the glazing panel.
Préférentiellement, la largeur de la fente 191 correspond sensiblement à la largeur de la carte de circuit imprimé 18 pour ne laisser s'échapper de polyisobutylène lors du remplissage du réservoir 19. Preferably, the width of the slot 191 corresponds substantially to the width of the printed circuit board 18 to allow escape of polyisobutylene during filling of the tank 19.
Selon une caractéristique avantageuse de l'invention, un couvercle peut être placé pour refermer le réservoir 19 pour obtenir un meilleur rendu esthétique après injection du polyisobutylène du second bouchon 20 à l'intérieur du réservoir 19. According to an advantageous characteristic of the invention, a cover can be placed to close the reservoir 19 to obtain a better rendering aesthetic after injection of the polyisobutylene of the second plug 20 inside the reservoir 19.
On a décrit ci-avant un mode de réalisation de l'invention selon lequel les premier et second bouchons sont distincts. Bien entendu, l'invention s'applique également dans le cas d'un unique bouchon global (par exemple en polyisobutylène) qui à la fois ferme l 'ouverture 122 autour de l' élément conducteur électrique 14 et enrobe la première extrémité 141 du câble électrique. An embodiment of the invention has been described above according to which the first and second plugs are distinct. Of course, the invention also applies in the case of a single overall plug (eg polyisobutylene) which both closes the opening 122 around the electrical conductor element 14 and covers the first end 141 of the cable electric.
On illustre en relation avec la figure 4, un procédé de fabrication d'un panneau de vitrage, en particulier panneau de vitrage isolant, selon un mode de réalisation de l'invention. FIG. 4 illustrates a method of manufacturing a glazing panel, in particular an insulating glazing panel, according to one embodiment of the invention.

- fermeture 403 de l'ouverture autour de l'élément conducteur électrique au moyen d'un premier bouchon de matériau élastomère thermoplastique. Bien entendu, l'invention n'est pas limitée aux exemples de réalisation mentionnés ci-dessus. En particulier, si l'invention a été ci-dessus illustrée au moyen de panneaux de vitrage isolants, elle fonctionne également avec tout type de panneau de vitrage et notamment avec des panneaux de vitrage non isolants. L'invention pourrait par exemple s'applique dans le cas d'un vitrage à deux feuilles de verre séparées par un cadre intercalaire prévu pour contenir des matériaux qui ne doivent pas entrer en contact avec l'atmosphère extérieur (par exemple des virus, bactéries, des gaz toxiques, ...). closing 403 of the opening around the electrically conductive element by means of a first plug of thermoplastic elastomer material. Of course, the invention is not limited to the embodiments mentioned above. In particular, if the invention has been illustrated above by means of insulating glazing panels, it also works with any type of glazing panel and in particular with non-insulating glazing panels. The invention could for example apply in the case of a glazing with two glass sheets separated by an intermediate frame intended to contain materials that must not come into contact with the outside atmosphere (for example viruses, bacteria , toxic gases, ...).
Par ailleurs, l'Homme du Métier pourra apporter toute variante dans les panneaux de vitrage selon l'invention décrit dans les figures précédentes. Par exemple, le panneau de vitrage peut comprendre plusieurs espaces internes (e.g. triple vitrage), chacun comprenant par exemple une lame de vide ou une lame de gaz (tout type de gaz y inclus l'air ainsi que leur mélanges) ou même une lame de liquide (le cas échéant des solides peuvent également être contenus dans l'un ou plusieurs des espaces internes), les feuilles de verres des panneaux de vitrage selon l'invention peuvent être constitués de tout type de verre, peuvent être texturés en surface, peuvent comprendre tout type de revêtements destinés à réaliser toute fonction, ou peuvent être eux-mêmes constitués de panneaux de vitrage laminés au moyen d'intercalaires plastiques... Moreover, the skilled person can make any variant in the glazing panels according to the invention described in the previous figures. For example, the glazing panel may comprise several internal spaces (eg triple glazing), each comprising for example a vacuum blade or a gas blade (any type of gas including air and mixtures thereof) or even a blade of liquid (where appropriate solids may also be contained in one or more of the internal spaces), the glass sheets of the glazing panels according to the invention may be made of any type of glass, may be textured on the surface, may include any type of coverings intended to perform any function, or may themselves consist of glazed panels laminated with plastic interleaves ...
Un panneau de vitrage selon l'invention peut être mis en œuvre dans tout type d'application tel que les fenêtres de bâtiments ou de véhicules, les cloisons, les mûrs, les baies vitrées (e.g. vérandas, éléments de toit, ...), les sols, escaliers, ... A glazing panel according to the invention can be implemented in any type of application such as windows of buildings or vehicles, partitions, ripe, bay windows (eg verandas, roof elements, ...) , floors, stairs, ...
