Description

La présente invention concerne un vitrage automobile pourvu d'une structure de conducteurs placée sur une surface de verre, qui comprend des conducteurs imprimés et cuits en place sur cette surface de verre ainsi que d'autres conducteurs, disposés dans un deuxième plan et isolés par rapport aux précédents.The present invention relates to automobile glazing provided with a conductor structure placed on a glass surface, which comprises printed conductors baked in place on this glass surface as well as other conductors, arranged in a second plane and insulated by compared to the previous ones.

Les vitrages automobiles équipés de conducteurs électriques cuits en place dans la surface du verre et constitués d'une encre à cuire contenant de l'argent métallique sont utilisés surtout comme vitrages chauffants (DE-AS 19 11 561) ou comme vitrages à antennes (DE 21 45 968 C3). En outre, on connaît des vitrages automobiles pourvus d'une structure de conducteurs cuite en place dans lesquels cette structure est une boucle d'alarme reliée à un transmetteur de signaux (BE 0 418 123 A1). Il est également connu que l'on peut réaliser des structures de conducteurs cuites en place dans la surface du verre en tant que détecteurs d'humidité (DE-PS 22 07 230), et placer directement sur la surface du verre, sous la forme de structures de conducteurs cuites en place, des inductances, des capacités et des câbles de blindage (DE 20 14 643).Automobile glazing fitted with electric conductors baked in place in the glass surface and made of a baking ink containing metallic silver is used mainly as heating glazing (DE-AS 19 11 561) or as antenna glazing (DE 21 45 968 C3). In addition, automobile glazings are known which are provided with a structure of conductors baked in place in which this structure is an alarm loop connected to a signal transmitter (BE 0 418 123 A1). It is also known that conductive structures baked in place in the surface of the glass can be produced as humidity detectors (DE-PS 22 07 230), and placed directly on the surface of the glass, in the form conductor structures baked in place, inductors, capacitors and shielding cables (DE 20 14 643).

Dans la pratique, les structures de conducteurs sur les surfaces de verre sont habituellement imprimées par sérigraphie et cuites en place, à une température élevée. Avec cette technique, on peut réaliser, à moindres frais, des structures de conducteurs relativement complexes dans un plan.In practice, the conductor structures on the glass surfaces are usually screen printed and baked in place at a high temperature. With this technique, it is possible to produce, relatively inexpensively, relatively complex conductor structures in a plane.

Dans bon nombre de cas, toutefois, il n'est pas suffisant de rester dans un plan. Par exemple, dans le cas de croisements de conducteurs où ceux-ci doivent être isolés les uns par rapport aux autres, ces conducteurs doivent être disposés dans des plans diférents aux points de croisement. Par le document DE 25 52 049 B2, on connaît une structure de conducteurs qui se croisent et qui sont isolés les uns par rapport aux autres. Avec cette structure de conducteurs connue, le problème du croisement est résolu du fait que des surfaces de connexion conductrices cuites en place sont reliées par des tronçons de conducteurs isolés du conducteur, cintrés en forme de pont, et mécaniquement solides, qui passent par-dessus les conducteurs cuits en place que l'on croise, en formant un arc en demi-cercle.In many cases, however, it is not enough to stay in a plan. For example, in the case of crossovers of conductors where these must be isolated from each other, these conductors must be arranged in diferent planes at the crossing points. By document DE 25 52 049 B2, a structure is known conductors that cross and are isolated from each other. With this known conductor structure, the crossing problem is solved by the fact that conductive connection surfaces baked in place are connected by sections of conductors isolated from the conductor, bent in the form of a bridge, and mechanically solid, which pass over conductors baked in place that we cross, forming an arc in a semicircle.

Il est également connu que l'on peut, à l'aide de la technique d'impression, réaliser des pistes conductrices multicouches, avec des couches isolantes placées entre les couches conductrices et ce, en plusieurs opérations d'impression successives (DE 39 11 178 C2). Cependant, ce procédé ne donne de résultats satisfaisants que si chaque couche est cuite séparément après l'opération d'impression. Dans la fabrication de vitrages automobiles, une telle cuisson multiple n'est pas possible, pour des raisons économiques et aussi pour des raisons techniques. En pratique, dans la réalisation de couches multiples sur des vitrages automobiles, on procède simplement à un séchage intermédiaire après chaque opération d'impression et, après la dernière de ces opérations d'impression, tout le paquet de couches est cuit en place en une seule opération. Toutefois, avec ce procédé, des courts-circuits se produisent sans cesse aux points de croisement, de sorte que cette méthode donne des déchets importants.It is also known that it is possible, using the printing technique, to produce multilayer conductive tracks, with insulating layers placed between the conductive layers, in several successive printing operations (DE 39 11 178 C2). However, this process only gives satisfactory results if each layer is cooked separately after the printing operation. In the manufacture of automotive glazing, such multiple baking is not possible, for economic reasons and also for technical reasons. In practice, in the production of multiple layers on automobile glazing, an intermediate drying is simply carried out after each printing operation and, after the last of these printing operations, the entire packet of layers is baked in place in one single operation. However, with this method, short circuits constantly occur at the crossing points, so that this method gives significant waste.

L'invention a pour but de procurer un vitrage automobile pourvu de conducteurs qui s'étendent en partie dans au moins deux plans, vitrage avec lequel, d'une part, le risque de courts-circuits aux croisements des conducteurs soit exclu de manière sûre, et qui, d'autre part, soit d'une fabrication simple dans les conditions de production habituelles.The object of the invention is to provide an automotive glazing provided with conductors which extend partly in at least two planes, glazing with which, on the one hand, the risk of short circuits at the crossings of the conductors is safely excluded , and which, on the other hand, is simple to manufacture under the usual production conditions.

Suivant l'invention, ce but est atteint du fait que les conducteurs placés dans un autre plan sont des rubans métalliques conducteurs qui se trouvent à l'intérieur d'un élément préfabriqué multicouche, comprenant au moins une couche isolante, qui est fixé à demeure par une couche d'adhésif sur la surface du vitrage pourvue des conducteurs cuits en place, et au-dessus de ceux-ci.According to the invention, this object is achieved because the conductors placed in another plane are metallic conductive ribbons which are located inside a prefabricated multilayer element, comprising at least one insulating layer, which is permanently fixed by a layer of adhesive on the surface of the glazing provided with baked conductors in place, and above these.

Les conducteurs ou les structures de conducteurs nécessaires dans un deuxième plan et, le cas échéant, dans d'autres plans de conducteurs, sont donc préfabriqués, suivant l'invention, sur un support fait d'une pellicule isolante monocouche ou multicouche, et les éléments préfabriqués multicouches sont appliqués, par laminage, à l'endroit voulu de la surface de verre, à la fin du processus de fabrication du vitrage. Les éléments préfabriqués sont pourvus de surfaces de connexion appropriées, par exemple de surfaces de connexions à souder, qui permettent de connecter électriquement les conducteurs de l'élément préfabriqué à la structure de conducteurs cuite en place et/ou aux câbles de connexion.The conductors or the structures of conductors necessary in a second plane and, where appropriate, in other plans of conductors, are therefore prefabricated, according to the invention, on a support made of a monolayer or multilayer insulating film, and the Prefabricated multilayer elements are applied, by rolling, to the desired location on the glass surface, at the end of the glazing manufacturing process. The prefabricated elements are provided with suitable connection surfaces, for example soldering connection surfaces, which allow the conductors of the prefabricated element to be electrically connected to the baked conductor structure and / or to the connection cables.

  • la Fig. 2 est une vue en coupe suivant la ligne II-II de la Fig. 1;

  • la Fig. 4 est une vue en coupe suivant la ligne IV-IV de la Fig. 3.
Different embodiments of the invention will be described in more detail below with reference to the appended drawings, in which:
  • Fig. 1 shows a part of a glazing provided with heating conductors, with a crossing of conductors in accordance with the invention;
  • Fig. 2 is a sectional view along line II-II of FIG. 1;
  • Fig. 3 represents a part of an automobile glazing provided with heating conductors, with an electronic module placed in the heating zone and an element which crosses the heating conductors and which is glued to the surface of the glass, and
  • Fig. 4 is a sectional view along the line IV-IV of FIG. 3.

Les Fig. 1 et 2 représentent un premier mode de réalisation d'un vitrage automobile conforme à l'invention. Le vitrage automobile représenté en partie ici est une lunette arrière à chauffage électrique dans laquelle des conducteurs chauffants (2) horizontaux sont imprimés et cuits en place sur le verre (1), et qui présente, en outre, un ou plusieurs conducteurs d'antenne séparés galvaniquement de ces conducteurs chauffants (2) et qui sont eux aussi imprimés et cuits en place. Les conducteurs d'antenne eux-mêmes ne sont pas représentés dans les figures. Le conducteur d'antenne placé au-dessus du conducteur chauffant (2) représenté est relié à un élément (3) d'enfichage analogue à un bouton-pression, qui est fixé près du bord inférieur de la lamelle de verre (1), c'est-à-dire au-dessous du conducteur chauffant (2), et auquel se connecte le câble menant à l'amplificateur d'antenne ou au récepteur.Figs. 1 and 2 show a first embodiment of an automotive glazing according to the invention. The automotive glazing shown in part here is an electrically heated rear window in which horizontal heating conductors (2) are printed and baked in place on the glass (1), and which also has one or more antenna conductors galvanically separated from these heating conductors (2) and which are also printed and baked in place. The antenna conductors themselves are not shown in the figures. The antenna conductor placed above the heating conductor (2) shown is connected to a plug-in element (3) similar to a press button, which is fixed near the lower edge of the glass strip (1), that is to say below the heating conductor (2), and to which the cable leading to the antenna amplifier or receiver is connected.

Le passage par-dessus le conducteur chauffant (2) se fait au moyen de l'élément multicouche séparé (6). Cet élément (6) présente, en tant que constituant conducteur de l'électricité, un mince ruban métallique (7) dont l'épaisseur est par exemple de 30 à 80 µm et la largeur de 1 à 10 mm. Au lieu du ruban métallique (7), le constituant conducteur de l'électricité peut aussi être un fil de cuivre de 0,1 à 1 mm de diamètre. Le ruban métallique (7), qui est de préférence en cuivre, est entouré d'une gaine isolante plate (8) faite d'une matière plastique appropriée résistant à la rupture. L'extrémité inférieure de l'élément (6) s'élargit en une section terminale (10) circulaire qui présente un oeillet central de soudage (11). Près de l'oeillet de soudage (11), la gaine isolante (8) est supprimée au-dessus et au-dessous du ruban métallique (7), formant un espace dégagé circulaire, et le ruban métallique (7) présente un trou concentrique (12). L'élément (6) est collé à la plaque de verre (1) par une couche d'adhésif (13).The passage over the heating conductor (2) is done by means of the separate multilayer element (6). This element (6) has, as an electrically conductive constituent, a thin metallic strip (7) whose thickness is for example from 30 to 80 μm and the width from 1 to 10 mm. Instead of the metallic strip (7), the electrically conductive constituent can also be a copper wire of 0.1 to 1 mm in diameter. The metal strip (7), which is preferably made of copper, is surrounded by a flat insulating sheath (8) made of a suitable plastic material resistant to breakage. The lower end of the element (6) widens into a circular end section (10) which has a central welding eyelet (11). Near the welding eyelet (11), the insulating sheath (8) is removed above and below the metal strip (7), forming a circular open space, and the metal strip (7) has a concentric hole. (12). The element (6) is bonded to the glass plate (1) by a layer of adhesive (13).

Comme matière pour la gaine isolante (8) de l'élément (6), gaine qui est fixée à demeure et durablement au ruban métallique (7), une matière plastique à base de polyimide, par exemple, a donné satisfaction, tandis que, comme adhésif pour la fixation de cet élément à la surface du verre, ce sont en particulier des adhésifs à base d'isoprène ou d'acrylate qui ont fait leurs preuves.As a material for the insulating sheath (8) of the element (6), a sheath which is permanently and permanently fixed to the metal strip (7), a plastic material based on polyimide, for example, has given satisfaction, while, as an adhesive for fixing this element to the surface of the glass, it is in particular adhesives based on isoprene or acrylate which have proved their worth.

La section terminale circulaire (10) de l'élément (6) repose sur une couche (15) d'émail conducteur et soudable à l'étain, qui, par exemple, est constituée de la même encre à cuire que les conducteurs chauffants (2) et le conducteur d'antenne et qui a été appliquée sur la surface de verre lors de la même opération d'impression que pour ceux-ci. L'élément d'enfichage ressemblant à un bouton-pression, d'une part, et l'oeillet de soudage (11) de l'élément (6), d'autre part, sont soudés à l'étain à cette couche d'émail conducteur (15). La soudure entre l'oeillet de soudage (11) et la couche d'émail conducteur (15) se fait, après la mise en place de l'élément (6) sur le vitrage (1), en déposant de la soudure à l'étain (16) à l'emplacement de l'oeillet de soudage (11); elle coule par le trou (12) du ruban métallique (7) et elle se soude à la couche d'émail conducteur (15).The circular terminal section (10) of the element (6) rests on a layer (15) of conductive enamel and solderable with tin, which, for example, consists of the same baking ink as the heating conductors ( 2) and the antenna conductor which was applied to the glass surface during the same printing operation as for these. The plug-like element, on the one hand, and the welding eyelet (11) of the element (6), on the other hand, are soldered with tin to this layer d conductive enamel (15). The welding between the welding eyelet (11) and the conductive enamel layer (15) is done, after the element (6) is placed on the glazing (1), by depositing solder on the 'tin (16) at the location of the welding eyelet (11); it flows through the hole (12) of the metallic tape (7) and it is welded to the layer of conductive enamel (15).

Les Fig. 3 et 4 représentent un autre mode de réalisation de l'invention. Dans ce cas, il s'agit également d'un vitrage automobile pouvant être chauffé électriquement, avec des conducteurs chauffants (19) imprimés et cuits en place sur le vitrage (18). Un module électronique doit être fixé sur le verre dans la zone de la surface chauffée. Ce module électronique peut être par exemple un détecteur d'humidité ou un autre montage électronique quelconque. Les conducteurs aboutissant à ce module, lequel n'est pas représenté dans les dessins en tant que tel, doivent de préférence être amenés, d'une façon respectant l'esthétique, au bord supérieur du vitrage (18), où il est prévu de connecter un câble compact assurant le reste de la liaison.Figs. 3 and 4 show another embodiment of the invention. In this case, it is also an automotive glazing that can be heated electrically, with heating conductors (19) printed and baked in place on the glazing (18). An electronic module must be attached to the glass in the area of the heated surface. This electronic module can be for example a humidity detector or any other electronic assembly. The conductors leading to this module, which is not shown in the drawings as such, should preferably be brought, in a manner that respects aesthetics, to the upper edge of the glazing (18), where provision is made for connect a compact cable ensuring the rest of the link.

Dans ce cas, le croisement des conducteurs chauffants (19) se fait au moyen d'un élément complexe (20) qui est laminé ou collé sur le vitrage (18). Cet élément (20) présente, à l'une de ses extrémités, une surface de montage (21) destinée au module et, à son autre extrémité, une surface de montage (22) destinée à un élément d'enfichage avec lequel la liaison au câble compact est établie. Le module électronique peut, à l'endroit de la surface de montage (21), être intégré directement à l'élément (20) ou bien, en tant que module distinct, être mis en place sur la surface de montage (21) à un moment ultérieur. De même, le cas échéant, l'élément d'enfichage peut, à l'endroit de la surface de montage (22), être intégré à l'élément (20) ou être mis en place plus tard sur cette surface de montage (22). L'élément (20) possède trois conducteurs, à savoir un conducteur d'alimentation (24), un conducteur de signalisation (25) et un conducteur de commande (26), qui sont reliés aux points de connexion correspondants, sur les surfaces de montage (21 et 22).In this case, the crossing of the heating conductors (19) is done by means of a complex element (20) which is laminated or glued to the glazing (18). This element (20) has, at one of its ends, a surface of mounting (21) intended for the module and, at its other end, a mounting surface (22) intended for a plug-in element with which the connection to the compact cable is established. The electronic module can, at the location of the mounting surface (21), be integrated directly into the element (20) or, as a separate module, be placed on the mounting surface (21) at a later time. Likewise, where appropriate, the plug-in element can, at the location of the mounting surface (22), be integrated into the element (20) or be placed later on this mounting surface ( 22). The element (20) has three conductors, namely a supply conductor (24), a signal conductor (25) and a control conductor (26), which are connected to the corresponding connection points, on the surfaces of mounting (21 and 22).

La Fig. 4 montre la structure multicouche de l'élément (20). Outre le conducteur d'alimentation (24), le conducteur de signalisation (25) et le conducteur de commande (26), qui, dans ce cas, sont disposés dans un plan, entre deux couches isolantes (27), à l'intérieur d'une couche d'adhésif (28), l'élément (20) présente, au-dessous du plan des conducteurs, une feuille métallique (29) qui s'étend de préférence sur toute la largeur de ce même élément (20). Cette feuille métallique (29) est reliée à la borne de masse (30), sur la surface de montage (21). La feuille métallique (29) sert de conducteur de masse et, en même temps, de conducteur de blindage. Au-dessus de la couche isolante supérieure (27), se trouve une autre couche d'adhésif (28) au milieu de laquelle est placé un autre ruban métallique (32) qui sert de conducteur de blindage supérieur pour le conducteur de signalisation (25) sousjacent. L'ensemble des couches est entouré d'une gaine isolante (34) faite d'une matière plastique résistant à la rupture, par exemple à base de polyimide. Cet élément (20) est collé solidement, à demeure, à la surface du vitrage (18), au moyen d'une couche d'adhésif (35).Fig. 4 shows the multilayer structure of the element (20). In addition to the supply conductor (24), the signal conductor (25) and the control conductor (26), which in this case are arranged in a plane, between two insulating layers (27), inside of a layer of adhesive (28), the element (20) has, below the plane of the conductors, a metal sheet (29) which preferably extends over the entire width of this same element (20) . This metal sheet (29) is connected to the ground terminal (30) on the mounting surface (21). The metal sheet (29) serves as a ground conductor and, at the same time, as a shield conductor. Above the upper insulating layer (27) is another layer of adhesive (28) in the middle of which is placed another metal strip (32) which serves as the upper shielding conductor for the signaling conductor (25 ) underlying. All of the layers are surrounded by an insulating sheath (34) made of a plastic material resistant to breakage, for example based on polyimide. This element (20) is permanently bonded securely to the surface of the glazing (18), by means of a layer of adhesive (35).

Les structures multicouches de ce genre sont connues, dans la technique des cartes à circuits imprimés, sous le nom de multicouches (en anglais : "multi-layer"). Les conducteurs peuvent être réalisés dans le cadre de procédés d'impression, par impression des feuilles isolantes (27), par application de minces rubans métalliques, par doublage sur les feuilles isolantes (27), ou bien par doublage d'une feuille isolante sur toute sa surface au moyen d'une feuille de cuivre et structuration de la feuille de cuivre à l'aide de la technique de gravure par attaque chimique. A l'aide de telles techniques connues, on réalise un câble plat et, par estampage ou formage à chaud, on obtient à partir de ce câble plat l'élément (20) dans sa forme souhaitée.Multilayer structures of this kind are known, in the technique of printed circuit boards, under the name of multilayers (in English: "multi-layer"). The conductors can be produced in the context of printing processes, by printing the insulating sheets (27), by applying thin metallic ribbons, by doubling on the insulating sheets (27), or by doubling an insulating sheet on its entire surface by means of a copper foil and structuring of the copper foil using the etching technique by chemical attack. Using such known techniques, a flat cable is produced and, by hot stamping or forming, the element (20) is obtained from this flat cable in its desired shape.

Après la fabrication du vitrage (18), l'élément (20) est collé sur la surface de ce vitrage.After the glazing (18) has been produced, the element (20) is bonded to the surface of this glazing.
