L'invention concerne une liaison entre au moins un point de connexion électrique, en particulier pour un système de capteur, et une piste conductrice appliquée sur une plaque, en particulier sur une The invention relates to a connection between at least one electrical connection point, in particular for a sensor system, and a conductive track applied to a plate, in particular to a
plaque de verre ou de vitrocéramique. glass or glass-ceramic plate.
Dans le document DE 40 22 845 C2, il est indiqué que des couches métalliques appliquées par un procédé de sérigraphie sur une plaque de vitrocéramique peuvent être reliées à des contacts électriques par brasure ou par collage. Cependant, on a constaté que le In document DE 40 22 845 C2, it is indicated that metal layers applied by a screen printing process to a glass ceramic plate can be connected to electrical contacts by soldering or by bonding. However, it was found that the
brasage ou le collage ne permettaient pas d'obtenir une liaison électro- soldering or gluing did not allow to obtain an electro-
conductrice parfaitement fiable dans le temps. conductor perfectly reliable over time.
Le document DE 197 07 664 A1 décrit une piste conductrice qui est appliquée sur une plaque de vitrocéramique. Etant donné que la réalisation des points de connexion sur la plaque de vitrocéramique utilisée comme plaque de cuisson est une opération complexe et chère, il est proposé une connexion mécanique au moyen de doigts de contact. Il est connu, de par le document WO 88/05 428 A1, de relier un composant électronique (puce) à une carte à circuit imprimé au moyen Document DE 197 07 664 A1 describes a conductive track which is applied to a glass-ceramic plate. Since the realization of the connection points on the glass ceramic plate used as a cooking plate is a complex and expensive operation, a mechanical connection is proposed by means of contact fingers. It is known from document WO 88/05 428 A1 to connect an electronic component (chip) to a printed circuit board by means
de bouts de fil soudés par un procédé de soudage par ultrasons. ends of wire welded by an ultrasonic welding process.
Des capteurs de température disposés sur une plaque de cuisson en vitrocéramique sont décrits dans les documents US 4 237 368 et DE 40 22 845 C2. Des pistes conductrices sont aménagées sur la plaque de vitrocéramique. L'agencement des points de connexion est Temperature sensors arranged on a ceramic hob are described in documents US 4,237,368 and DE 40 22,845 C2. Conductive tracks are arranged on the glass ceramic plate. The arrangement of connection points is
laissé ouvert.left open.
Par le document DE 197 11 541 A1, on apprend que l'on peut coller un film métallique sur la face inférieure pourvue de reliefs en From document DE 197 11 541 A1, we learn that we can stick a metal film on the underside provided with reliefs
forme de boutons d'une plaque de cuisson en vitrocéramique. shaped like buttons on a ceramic hob.
Le document DE 692 04 564 T2 décrit un procédé de métallisation sans courant électrique d'un modèle en un matériau autre que du verre, appliqué sur un support en verre. La métallisation doit permettre la réalisation de liaisons avec des éléments électriques, en particulier par soudage par ultrasons. Le but de la présente invention est de proposer une liaison du type indiqué en introduction, qui soit résistante à la corrosion, résistante aux chocs thermiques, résistante à la traction et Document DE 692 04 564 T2 describes a metallization process without electric current of a model made of a material other than glass, applied to a glass support. The metallization must allow the creation of connections with electrical elements, in particular by ultrasonic welding. The object of the present invention is to provide a connection of the type indicated in the introduction, which is resistant to corrosion, resistant to thermal shock, resistant to traction and
électriquement conductrice.electrically conductive.
Ce but est atteint conformément à l'invention par le fait que la piste conductrice est appliquée sur une surface de la plaque pourvue de reliefs en forme de boutons et que l'élément de liaison est soudé par ultrasons à l'ensemble composite formé de la piste conductrice et de la This object is achieved in accordance with the invention by the fact that the conductive track is applied to a surface of the plate provided with reliefs in the form of buttons and that the connecting element is welded by ultrasound to the composite assembly formed of the conductive track and the
plaque, au niveau d'un vallon entre boutons. plate, at the level of a valley between buttons.
Avec le soudage par ultrasons de l'élément de liaison sur l'ensemble composite formé de la piste conductrice et de la plaque, la fixation de l'élément de liaison sur la piste conductrice n'est pas seulement superficielle, comme c'est le cas dans une liaison soudée ou dans une liaison collée. Au contraire, on obtient avec le soudage par ultrasons une liaison qui traverse la piste conductrice très fine et implique celle- ci. On a ainsi, en plus de la liaison résultant de l'application de la couche conductrice sur la plaque, une force de liaison supplémentaire entre la piste conductrice et la plaque. Avec le soudage par ultrasons, les trois éléments de la liaison, à savoir la plaque, la piste conductrice et l'élément de liaison, sont assemblés de manière homogène. Il s'ensuit que l'élément de liaison est fixé d'une manière durable, résistante à la traction et aux chocs thermiques, à l'ensemble composite formé de la plaque et de la piste conductrice, et With ultrasonic welding of the connecting element on the composite assembly formed of the conductive track and the plate, the fixing of the connecting element on the conductive track is not only superficial, as is the case in a welded connection or in a bonded connection. On the contrary, with ultrasonic welding, a connection is obtained which crosses the very fine conductive track and involves it. There is thus, in addition to the bond resulting from the application of the conductive layer on the plate, an additional bonding force between the conductive track and the plate. With ultrasonic welding, the three elements of the connection, namely the plate, the conductive track and the connection element, are assembled in a homogeneous manner. It follows that the connecting element is fixed in a durable manner, resistant to traction and to thermal shock, to the composite assembly formed by the plate and the conductive track, and
plus particulièrement à la plaque en tant qu'élément de support stable. more particularly to the plate as a stable support element.
Malgré les coefficients de dilatation thermique très différents de la plaque et de la piste conductrice, aucun décollement de la liaison n'est Despite the very different thermal expansion coefficients of the plate and the conductive track, no separation of the bond is
à craindre.to fear.
Avec le soudage par ultrasons, on obtient automatiquement une With ultrasonic welding, you automatically get a
conductivité élevée entre l'élément de liaison et la piste conductrice. high conductivity between the connecting element and the conductive track.
La liaison réalisée par soudage par ultrasons offre également une résistance à la corrosion nettement plus élevée qu'une liaison soudée The connection produced by ultrasonic welding also offers a significantly higher corrosion resistance than a welded connection
traditionnelle ou une liaison collée. traditional or a bonded bond.
Avec le soudage par ultrasons, à la différence d'une liaison soudée, on évite que la plaque, en particulier la plaque en vitrocéramique, soit soumise localement à une sollicitation thermique With ultrasonic welding, unlike a welded connection, it is avoided that the plate, in particular the glass-ceramic plate, is locally subjected to a thermal stress
élevée, pouvant nuire à sa tenue dans le temps. high, which could affect its durability over time.
La plaque présente une surface pourvue de reliefs en forme de boutons, la ou les pistes conductrices étant appliquées sur la surface portant les reliefs en forme de boutons. Pour améliorer la structure et obtenir une liaison sûre, l'élément de liaison est soudé par ultrasons à l'ensemble composite formé de la plaque et de la piste conductrice au The plate has a surface provided with reliefs in the form of buttons, the conductive track or tracks being applied to the surface carrying the reliefs in the form of buttons. To improve the structure and obtain a secure connection, the connection element is ultrasonically welded to the composite assembly formed by the plate and the conductive track at the
niveau d'un vallon entre boutons.level of a valley between buttons.
L'élément de liaison qui, par exemple, est un fil (fil de jonction) en un matériau de type Al-Si s'étend jusqu'au point de connexion fixé à la plaque et est connecté électriquement et relié mécaniquement audit point de connexion, ce qui peut être réalisé par The connecting element which, for example, is a wire (connecting wire) made of an Al-Si type material extends to the connection point fixed to the plate and is electrically connected and mechanically connected to said connection point , which can be achieved by
soudage traditionnel ou par soudage par ultrasons. traditional or ultrasonic welding.
De préférence le point de connexion est disposé sur une platine de connexion - comme cela est courant en électronique - la platine de Preferably the connection point is arranged on a connection plate - as is common in electronics - the connection plate
connexion étant fixée à la plaque, en particulier étant collée à celle-ci. connection being fixed to the plate, in particular being glued to the latter.
Du point de connexion concerné, un cable électrique, par exemple, mène à un circuit électronique dont les détecteurs sont constitués par From the connection point concerned, an electric cable, for example, leads to an electronic circuit, the detectors of which consist of
la ou les pistes conductrices.the conductive track or tracks.
La piste conductrice, dont l'épaisseur est considérablement plus faible que celle de la plaque et est par exemple d'environ 100 nm, est appliquée sur la plaque de préférence par un procédé de sérigraphie, The conductive track, the thickness of which is considerably smaller than that of the plate and is for example around 100 nm, is applied to the plate preferably by a screen printing process,
par projection cathodique ou par dépôt en phase vapeur. by cathodic projection or by vapor deposition.
Pour protéger l'élément de liaison, plus particulièrement pour le protéger de la corrosion, ledit élément de liaison est noyé dans une To protect the connecting element, more particularly to protect it from corrosion, said connecting element is embedded in a
masse de protection qui s'étend depuis le point de connexion jusqu'au- protective mass which extends from the connection point to
delà du point de soudage par ultrasons. La masse de protection est par exemple une résine époxyde thermodurcissable, sélectionnée en vue beyond the point of ultrasonic welding. The protective mass is for example a thermosetting epoxy resin, selected in view
d'obtenir une bonne adhérence sur l'ensemble composite plaque-piste conductrice. to obtain good adhesion on the composite plate-conductive track.
La liaison décrite peut être appliquée par exemple à une plaque de vitrocéramique faisant partie d'une plaque de cuisson, les pistes conductrices constituant dans ce cas des surfaces sensibles et les points de connexion étant reliés à un système de capteur électronique. La liaison décrite peut aussi être appliquée à des plaques de verre, qui constituent par exemple les vitres de The described connection can be applied for example to a glass-ceramic plate forming part of a cooking plate, the conductive tracks constituting in this case sensitive surfaces and the connection points being connected to an electronic sensor system. The described bond can also be applied to glass plates, which constitute for example the panes of

Une plaque de vitrocéramique 1 présente une surface 2 formant surface de pose pour des casseroles. Sur son autre surface 3 sont prévues des conformations ou reliefs en forme de boutons 4. La hauteur des boutons est par exemple comprise dans une plage allant de gm à 200 im. Des dispositifs de chauffage rayonnants courants sont associés à la plaque de vitrocéramique 1. Au moins une piste conductrice 5 est appliquée par sérigraphie, par projection cathodique ou par dépôt en phase vapeur sur la surface 3. La piste conductrice 5, dans les plaques de cuisson, sert de surface sensible de détection pour détecter les casseroles ou pour la mesure de température. La piste conductrice, dans une porte de four à micro-ondes, peut servir de blindage électromagnétique. Dans les portes de four de cuisson et les hublots de cheminées, la piste conductrice peut être prévue pour des A vitroceramic plate 1 has a surface 2 forming a laying surface for pans. On its other surface 3 are provided conformations or reliefs in the form of buttons 4. The height of the buttons is for example in a range from gm to 200 im. Common radiant heaters are associated with the ceramic hob 1. At least one conductive track 5 is applied by screen printing, by cathode spraying or by vapor deposition on the surface 3. The conductive track 5, in the cooking plates , serves as a sensitive detection surface for detecting pans or for temperature measurement. The conductive track, in a microwave oven door, can serve as electromagnetic shielding. In baking oven doors and chimney windows, the conductive track can be provided for
raisons de sécurité, pour la mesure de la température. security reasons, for temperature measurement.
De préférence, la piste conductrice 5 est formée d'une couche de métal précieux, en particulier à base d'or ou de platine, dont le coefficient de dilatation thermique est sensiblement plus élevé que celui de la plaque 1. La piste conductrice 5 est appliquée sous forme de pâte à base de résine, par un procédé de Preferably, the conductive track 5 is formed of a layer of precious metal, in particular based on gold or platinum, whose coefficient of thermal expansion is substantially higher than that of the plate 1. The conductive track 5 is applied in the form of a paste based on resin, by a process of
sérigraphie. La piste conductrice 5 à une épaisseur d'environ 100 nm. screen printing. The conductive track 5 has a thickness of about 100 nm.
Elle suit le relief des boutons et des vallons entre boutons (voir figure) . Une platine de connexion 6 est fixée à la surface 3 au moyen d'un adhésif 7. La platine de connexion 6 s'étend sur deux boutons ou plus, les vallons entre boutons étant comblés avec de l'adhésif 7. La It follows the relief of the buttons and valleys between buttons (see figure). A connection plate 6 is fixed to the surface 3 by means of an adhesive 7. The connection plate 6 extends over two or more buttons, the valleys between buttons being filled with adhesive 7. The
platine de connexion 6 porte plusieurs surfaces de connexion 8 électro- connection plate 6 carries several connection surfaces 8 electro-
conductrices, dont une seulement est visible sur la figure. Un câble 9 électrique est relié à la surface de connexion 8, ou aux surfaces de connexion, dans une zone 10. Le câble 9 mène à un circuit électronique. Une liaison soudée ou une liaison à enfichage peut être prévue dans la zone 10, un des éléments de la liaison à enfichage étant conductive, only one of which is visible in the figure. An electric cable 9 is connected to the connection surface 8, or to the connection surfaces, in a zone 10. The cable 9 leads to an electronic circuit. A welded connection or a plug connection may be provided in zone 10, one of the elements of the plug connection being
alors fixé à la platine de connexion 6. then fixed to the connection plate 6.
Pour relier la surface de connexion 8 à la piste conductrice 5, il est prévu un élément de liaison qui est formé d'un bout de fil. Le bout de fil 11 est un fil de jonction en un matériau de type Al-Si. Le fil a To connect the connection surface 8 to the conductive track 5, there is provided a connecting element which is formed of a piece of wire. The end of the wire 11 is a connecting wire made of an Al-Si type material. The wire has
par exemple un diamètre d'environ 0,1 mm. for example a diameter of about 0.1 mm.
L'une des extrémités du bout de fil 11 est soudée par un procédé à ultrasons à l'ensemble composite formé de la plaque de vitrocéramique 1 et de la piste conductrice 5. Le point de soudage est désignée de manière symbolique 12. Le bout de fil 11 lié par soudage ou le point de soudage 12 se termine de préférence sur la surface, ou de manière avantageuse dans la piste conductrice 5, car les informations doivent être transmises à travers celle-ci. Le point de soudage 12 est situé dans un vallon entre boutons, ce qui évite une dégradation de la piste conductrice 5, particulièrement sensible dans la région des sommets des boutons. Avec le soudage par ultrasons, on ne se limite pas seulement à connecter le bout de fil 11 à la piste conductrice 5 qui adhère exclusivement par l'effet de liaison résultant de l'application de ladite piste conductrice 5 sur la plaque de vitrocéramique. Par le procédé de soudage par ultrasons, on obtient une liaison supplémentaire entre la piste conductrice 5 et la plaque de vitrocéramique 1, dans la région du point de soudage 12 et au final, l'extrémité du bout de fil 11 est soudée à la plaque de vitrocéramique 1 dans la région du point de soudage 12. La résistance à la traction est d'au moins 200 cN. La résistance élevée de la liaison est obtenue grâce au soudage par ultrasons malgré des coefficients de dilatation thermique très différents pour la plaque de vitrocéramique 1 et pour la piste conductrice 5 soient. Dans la liaison bout de fil en un matériau de type Al-Si 11 - piste conductrice 5, en particulier piste conductrice en or, les matériaux mis en oeuvre sont très ductiles et -la finesse de la couche aidant - ils absorbent les différences de dilatation. La conductibilité thermique de la vitrocéramique est faible. Elle est de l'ordre de 1,5 W/mK. En revanche, la conductibilité thermique de la One of the ends of the end of the wire 11 is welded by an ultrasonic process to the composite assembly formed by the glass-ceramic plate 1 and the conductive track 5. The welding point is symbolically designated 12. The end of wire 11 bonded by welding or the welding point 12 preferably ends on the surface, or advantageously in the conductive track 5, because the information must be transmitted through it. The welding point 12 is located in a valley between buttons, which prevents degradation of the conductive track 5, which is particularly sensitive in the region of the tops of the buttons. With ultrasonic welding, it is not limited solely to connecting the end of the wire 11 to the conductive track 5 which adheres exclusively by the bonding effect resulting from the application of said conductive track 5 on the glass-ceramic plate. By the ultrasonic welding process, an additional connection is obtained between the conductive track 5 and the glass-ceramic plate 1, in the region of the welding point 12 and in the end, the end of the wire end 11 is welded to the plate. of ceramic glass 1 in the region of the welding point 12. The tensile strength is at least 200 cN. The high resistance of the connection is obtained by ultrasonic welding despite very different thermal expansion coefficients for the glass ceramic plate 1 and for the conductive track 5 are. In the end-of-wire connection of a material of Al-Si 11 type - conductive track 5, in particular conductive track in gold, the materials used are very ductile and - the thinness of the layer helping - they absorb the differences in expansion . The thermal conductivity of the glass ceramic is low. It is around 1.5 W / mK. However, the thermal conductivity of the
piste conductrice 5 est élevée.conductive track 5 is high.
La résistance électrique de contact entre la piste conductrice 5 et le bout de fil 11 est faible, du fait du soudage par ultrasons. Elle est The electrical contact resistance between the conductive track 5 and the end of the wire 11 is low, due to ultrasonic welding. She is
inférieure à 0,1 Ohm.less than 0.1 Ohm.
La soudure réalisée par ultrasons est également résistante aux chocs thermiques et à la corrosion, ce qui est avantageux notamment lorsque, comme c'est le cas dans des appareils de cuisson, la liaison The ultrasonic welding is also resistant to thermal shock and corrosion, which is advantageous in particular when, as is the case in cooking appliances, the connection
est exposée à des températures élevées et à l'humidité. is exposed to high temperatures and humidity.
Le bout de fil 11l s'étend sur un ou plusieurs boutons 4, en formant un arc libre, jusqu'à la surface de connexion 8 et est relié à celle-ci en un point 13. Une liaison par brasage, par soudage, par soudage par ultrasons ou par serrage peut être prévue en ce point. La flexion libre du bout de fil 11 entre les points 12 et 13 apporte une certaine élasticité ou flexibilité, avantageuse pour compenser les tolérances et également compenser les différences de dilatation thermique. Afin de protéger le bout de fil 11 et les points de connexion 12 et 13 des influences extérieures, il est prévu une masse de protection 14, sous la forme d'un bourrelet qui entoure le bout de fil 11 et recouvre les points de connexion 12 et 13. La masse de protection 14 adhère à la plaque de vitrocéramique 1 et à la piste conductrice 5. La masse de protection 14 est formée par exemple d'une résine époxyde thermodurcissable. La piste conductrice 5 peut servir de surface sensible pour divers cas d'applications. Elle peut servir à détecter une casserole dans le cas d'une table de cuisson ou bien être utilisée comme capteur de température, auquel cas, elle présente une résistance qui varie en fonction de la température. The end of the wire 11l extends over one or more buttons 4, forming a free arc, up to the connection surface 8 and is connected to the latter at a point 13. A connection by soldering, by welding, by ultrasonic or clamp welding may be provided at this point. The free bending of the end of the wire 11 between the points 12 and 13 provides a certain elasticity or flexibility, advantageous for compensating for the tolerances and also compensating for the differences in thermal expansion. In order to protect the end of the wire 11 and the connection points 12 and 13 from external influences, a protective mass 14 is provided, in the form of a bead which surrounds the end of the wire 11 and covers the connection points 12 and 13. The protective mass 14 adheres to the glass ceramic plate 1 and to the conductive track 5. The protective mass 14 is formed for example from a thermosetting epoxy resin. The conductive track 5 can serve as a sensitive surface for various application cases. It can be used to detect a pan in the case of a hob or be used as a temperature sensor, in which case, it has a resistance which varies depending on the temperature.
