Description

Die Erfindung betrifft ein elektrisches Verbindungselement für eine Scheibe, die mit elektrischen Leiterkomponenten ausgestattet sind, wie etwa elektrische Anschlussflächen leitender Strukturen, die auf der Oberfläche der Scheibe der Art Antennenfeld oder Heizungsfeld aufgebracht sind, welche durch leitende bedruckte Drähte oder der Art elektrisch leitender Schichten gebildet sind. Das Verbindungselement dient dazu, die leitenden Strukturen der Scheibe mit einem elektrischen System oder elektrischen Systemen elektrisch zu verbinden, welche außerhalb der Scheibe angeordnet sind (Verstärker, Steuereinheiten, Spannungsquelle). Die Erfindung findet insbesondere bei Heizscheiben oder Antennen Anwendung.The invention relates to a disk electrical connector provided with electrical conductor components, such as electrical pads of conductive structures, deposited on the surface of the antenna array or heater panel disk formed by conductive printed wires or the nature of electrically conductive layers are. The connecting element serves to electrically connect the conductive structures of the disc with an electrical system or electrical systems which are arranged outside the disc (amplifiers, control units, voltage source). The invention finds particular application in heating disks or antennas application.

Zur Ausgestaltung einer Heizscheibe der Art Heckscheibe eines Autos wird mittels Siebdruck die Ablagerung eines Glasfilms einer Reihe von schmalen Widerstandsbändern, die aus einer teigigen Suspension gefertigt sind, in einem organischen Bindemittel aus metallenem Silber und einer Glasmasse, anders ausgedrückt einem Glas mit niedrigem Schmelzpunkt, vorgenommen. Nach dem Brennen wird ein Netz aus feinen elektrisch leitenden Bändern erhalten, welche auf größere Sammelbänder aus einer analogen Zusammensetzung zulaufen, die in der Nähe der Kanten des Glasfilms angeordnet sind, um die Sicht des Fahrers nicht zu behindern. Auf diese seitlichen Sammelbänder werden anschließend metallische Verbindungsteile geschweißt, die Kabelschuhe für das Stromnetz des Fahrzeugs bilden.To form a rear window of a car type automobile, screen printing is used to deposit a glass film of a series of narrow resistance bands made of a doughy suspension in an organic binder of metallic silver and a glass mass, in other words a low melting point glass , After firing, a net of fine electroconductive tapes is obtained, which run on larger collection tapes of an analogous composition, which are arranged in the vicinity of the edges of the glass film, so as not to hinder the driver's view. On this lateral collecting bands then metallic connecting parts are welded, forming the cable lugs for the power network of the vehicle.

Diese metallenen Verbindungsteile sind zum Beispiel aus steifen Platten aus Kupfer in T-Form ausgebildet, deren zwei Zweige durch Füße verlängert sind, unter denen die Lötung abgelagert ist. Das Verbindungsteil wird mittels eines beliebigen bekannten Verfahrens erhitzt, wie etwa mittels Leitung oder Konvektion, um die Lötung schmelzen zu lassen und nach der Auskühlung eine permanente Verbindung zwischen dem Sammelband und dem Verbindungsteil zu gewährleisten.These metal connecting parts are formed, for example, of rigid plates of T-shaped copper, the two branches of which are extended by feet, among which Solder is deposited. The connector is heated by any known method, such as by conduction or convection, to melt the braze and, after cooling, to provide a permanent connection between the collector and the connector.

Seit Langem weist die benutzte Lötung aufgrund ihrer zweckmäßigen duktilen Eigenschaft eine Basis von Blei auf. Tatsächlich ermöglicht dieses Metall die Minimierung der Spannungen, die im Scheibenglas in der Lötungszone während schneller Auskühlungsvorgänge und Temperaturanstiegen der Scheibe, die mit ihrem steifen Verbindungsteil versehen ist, auftreten können, zum Beispiel während Wärmewiderstandstests, für welche die Scheiben in einem geschlossenen Gehäuse Temperaturschwankungszyklen in diesem Gehäuse zwischen -40 °C und +90 °C unterzogen werden.For a long time, the solder used has a base of lead because of its proper ductile property. In fact, this metal allows for the minimization of the stresses that can occur in the glass pane in the soldering zone during rapid cooling and temperature increases of the disk provided with its rigid connection part, for example during thermal resistance tests, for which the disks in a closed casing have variations in temperature therein Housing between -40 ° C and +90 ° C be subjected.

Aus Umweltschutzgründen ist es notwendig, das Blei durch andere Materialien zu ersetzen, wie etwa Legierungen auf Zinnbasis. Jedoch ist Zinn ein viel weniger duktiles Material. Seine Anwesenheit zwischen einem steifen metallenen Verbindungsteil und dem Glasfilm, der mit der Komponente zum Verbinden versehen ist, dient sicherlich der Gewährleistung eines elektrischen Anschlusses und einer mechanischen Erhaltung des Teils, führt aber schließlich zu einem direkten Kontakt zwischen dem steifen Teil und dem Glasfilm. Beim Zurückziehen des metallenen Teils, insbesondere, wenn es einer starken Temperaturauskühlung unterzogen wird, bringt dieser direkte Kontakt zwischen dem Teil und dem Glas grundsätzlich das Auftreten von Spannungen im Glas mit sich. In Verbindung mit der Tatsache, dass das benutzte Glas immer dünner wird und dass es nicht gehärtet (also weniger widerstandsfähig) sein kann, führen die Spannungen im Glas meistens zum Bruch der Scheibe.For environmental reasons, it is necessary to replace the lead with other materials, such as tin based alloys. However, tin is a much less ductile material. Its presence between a rigid metal connection part and the glass film provided with the component for connection certainly serves to ensure electrical connection and mechanical preservation of the part, but eventually leads to direct contact between the rigid part and the glass film. Upon retraction of the metal part, especially when subjected to severe temperature cooling, this direct contact between the part and the glass basically results in the occurrence of stresses in the glass. In connection with the fact that the glass used becomes thinner and thinner and that it can not be hardened (ie less resistant), the stresses in the glass usually lead to breakage of the glass.

Eine weitere Lösung des Verbindungselements kann darin bestehen, einen flachen Träger aus Kunststoff zu benutzen, der durch Kleben auf dem Glasfilm befestigt wird, wobei metallene Elemente in diesen Träger eingeschlossen sind und an einem freien Ende elektrische Anschlussstellen umfassen, die von dem Träger hervorstehen, um mit den elektrischen Komponenten der Scheibe fest verbunden zu werden, wobei die elektrische Verbindung mit einem steifen Teil eines Leistungssteckers am entgegengesetzten Ende der metallenen Elemente und des Trägers aus Kunststoffmaterial stattfindet. Der Träger aus Kunststoff gestattet die Befestigung der Verbindungselements und führt nicht zu direktem Kontakt zwischen dem steifen Teil und den elektrischen Komponenten der Scheibe.Another solution of the fastener may be to use a flat plastic support which is adhesively secured to the glass film, with metal elements enclosed in this support and comprising at a free end electrical terminals protruding from the support to be firmly connected to the electrical components of the disc, wherein the electrical connection takes place with a rigid part of a power connector at the opposite end of the metal elements and the carrier made of plastic material. The plastic carrier allows the attachment of the connecting element and does not lead to direct contact between the rigid part and the electrical components of the disc.

Eine derartige Konfiguration ist zum Beispiel in den Patenten EP 766 338 B1 oder EP 1 657 964 A1 beschrieben. Diese Lösung hat sich jedoch als kostspielig erwiesen, insbesondere aufgrund der Notwendigkeit des Trägers aus Kunststoff und der Umhüllung der metallenen Elemente in diesem Träger.Such a configuration is for example in the patents EP 766 338 B1 or EP 1 657 964 A1 described. However, this solution has proved costly, in particular due to the need for the plastic carrier and the wrapping of the metallic elements in this carrier.

Es ist daher eine Aufgabe der Erfindung, eine Lösung der elektrischen Verbindung auf einer Scheibe bereitzustellen, die ohne Benutzung von Blei die Nachteile der Erzeugung von Spannungen im Glas minimiert, während die Scheibe Temperaturschwankungen unterzogen wird, ohne dabei die Herstellungskosten dieser Verbindung und schließlich diejenigen der Scheibe zu erhöhen.It is therefore an object of the invention to provide a solution of the electrical connection on a disc that minimizes the disadvantages of generating stresses in the glass without the use of lead, while the wafer is subjected to temperature fluctuations, without losing the manufacturing cost of this compound and finally those of Increase disc.

Erfindungsgemäß ist das elektrische Verbindungselement, das zum Verbinden mit mindestens einer elektrisch leitenden Komponente einer Scheibe bestimmt ist und einen elektrisch leitenden Körper umfasst, dadurch gekennzeichnet, dass der elektrisch leitende Körper mindestens einen elektrisch leitenden Film umfasst, der eine Dicke von zwischen 1 und 500 µm aufweist, wobei der Film mindestens eine elektrische Anschlussfläche aufweist, die dazu bestimmt ist, mit der Komponente in Kontakt zu sein, und mindestens eine Befestigungsfläche, die dazu bestimmt ist, das Verbindungselement auf der Scheibe zu befestigen, und dadurch, dass der Körper einen elektrisch leitenden steifen Abschnitt oder ein elektrisch leitendes steifes Teil umfasst, der/das an den Film angeschlossen ist oder an diesen angeschlossen werden soll, wobei der Körper Zwischenmittel aufweist, sodass der steife Abschnitt oder das steife Teil nicht dazu bestimmt ist, direkt mit der Scheibe über die einzige Dicke des Films in Kontakt zu sein.According to the invention, the electrical connection element, which is intended for connection to at least one electrically conductive component of a pane and comprises an electrically conductive body, is characterized in that the electrically conductive body comprises at least one electrically conductive film having a thickness of between 1 and 500 μm having, the film has at least one electrical pad intended to be in contact with the component and at least one mounting surface intended to secure the connector to the disk and in that the body has an electrically conductive rigid portion or an electrically conductive rigid part connected to or to be connected to the film, the body having intermediate means such that the rigid portion or the rigid part is not intended to be directly with the disc over the single thickness to be in contact with the film.

Der elektrisch leitende Film ermöglicht somit gleichzeitig den elektrischen Anschluss des Verbindungselementes sowie seine Befestigung. Somit dient er direkt als Träger zur Befestigung des Elements auf der Scheibe.The electrically conductive film thus simultaneously enables the electrical connection of the connecting element and its attachment. Thus, it serves directly as a carrier for fixing the element on the disc.

Außerdem ermöglicht seine geringe Dicke, die weniger als 500 µm beträgt, vorzugsweise zwischen 1 und 200 µm und insbesondere zwischen 1 und 100 µm liegt, dass keine starken Spannungen über das Glas erzeugt werden, wenn das Verbindungselement Temperaturschwankungszyklen unterzogen wird.In addition, its small thickness, which is less than 500 microns, preferably between 1 and 200 microns, and more preferably between 1 and 100 microns, that no strong stresses are generated on the glass when the connecting element is subjected to temperature fluctuation cycles.

Dieses Verbindungselement ermöglicht des Weiteren mittels Zwischenmitteln das Verhindern eines direkten Kontaktes zwischen der Scheibe und dem steifen Abschnitt oder dem steifen Teil, das Verbinden außerhalb der Scheibe und ist anfällig für Wärmespannungen. Daher besteht keine Übertragung von Wärmespannungen im Glas.This connecting element further allows by means of intermediate means the prevention of direct contact between the disc and the rigid portion or the rigid part, the connection outside the disc and is susceptible to thermal stresses. Therefore, there is no transfer of thermal stress in the glass.

Nach einer Charakteristik sind die Zwischenmittel stoßdämpfende Zwischenmittel; sie sind nicht aus reinem Metall und verhindern somit das Ausbilden einer steifen Verbindung, die zur Übertragung von Spannungen zwischen dem steifen Abschnitt des Körpers des Verbindungselements oder des steifen angeschlossenen Teils und der Scheibe fähig ist. Die Zwischenmittel bilden somit eine ausreichend duktile mechanische Verbindung.According to one characteristic, the intermediate means are shock-absorbing intermediate means; they are not made of pure metal and thus prevent the formation of a rigid connection, which is responsible for the transmission of stresses between the rigid portion of the body of the connecting element or the rigidly connected part and the disc. The intermediate means thus form a sufficiently ductile mechanical connection.

Die Zwischenmittel bestehen aus einem stoßdämpfenden Material oder aus einer Luftschicht, die auf einer der Oberflächen des elektrisch leitenden Films angeordnet ist oder angeordnet werden soll, wobei sie gegenüber dem steifen Abschnitt oder dem steifen Teil befindlich ist.The intermediate means consist of a shock-absorbing material or of an air layer which is arranged or should be arranged on one of the surfaces of the electrically conductive film, being located opposite the stiff portion or the rigid part.

Das stoßdämpfende Material ist zum Beispiel auf Kunststoffbasis. Das stoßdämpfende Material kann dennoch elektrisch leitend sein, indem es zum Beispiel Metallteilchen enthält.The shock absorbing material is for example based on plastic. The shock-absorbing material may nevertheless be electrically conductive, for example by containing metal particles.

Nach einer weiteren Charakteristik weisen die Zwischenmittel eine Dicke von 1 bis 2500 µm auf.According to another characteristic, the intermediate means have a thickness of 1 to 2500 microns.

Vorteilhafterweise ist der elektrisch leitende Film ein biegsamer metallener Film; wobei das Metall den Vorteil hat, formbar zu sein, einen hohen Schmelzpunkt und eine hohe elektrische Leitfähigkeit aufzuweisen. Der Film kann insbesondere auf Silber-, Kupfer-, Gold- oder Aluminiumbasis vorliegen.Advantageously, the electrically conductive film is a flexible metallic film; wherein the metal has the advantage of being malleable, having a high melting point and high electrical conductivity. In particular, the film may be silver, copper, gold or aluminum based.

Als Beispiel kann der elektrisch leitende Film eine oder mehrere Metallschichten umfassen, insbesondere mindestens eine Kupferschicht und mindestens eine Schicht, die Silber, Zinn und/oder Kupfer enthält, wobei diese Schicht dazu bestimmt ist, mit der Komponente der Scheibe in Kontakt zu sein.By way of example, the electrically conductive film may comprise one or more metal layers, in particular at least one copper layer and at least one layer containing silver, tin and / or copper, which layer is intended to be in contact with the component of the disk.

Nach einer weiteren Charakteristik der Erfindung ist die Befestigungsfläche des elektrisch leitenden Films von der elektrischen Anschlussfläche getrennt oder aus der elektrischen Anschlussfläche gebildet.According to a further characteristic of the invention, the attachment surface of the electrically conductive film is separated from the electrical connection surface or formed from the electrical connection surface.

Vorzugsweise ist die elektrische Anschlussfläche dazu bestimmt, elektrisch leitenden Kleber aufzunehmen oder dazu bestimmt, verlötet oder verschweißt zu werden.Preferably, the electrical pad is intended to receive electrically conductive adhesive or to be soldered or welded.

Vorteilhafterweise umfasst die Befestigungsfläche Befestigungsmittel.Advantageously, the attachment surface comprises attachment means.

Die Befestigungsmittel können durch ein doppelseitiges Klebeband ausgebildet sein, das vorzugsweise auf der Oberfläche, die derjenigen gegenüber der Befestigungsfläche entgegengesetzt ist, mit einer Schutzbeschichtung versehen ist.The fastening means may be formed by a double-sided adhesive tape, which is preferably provided with a protective coating on the surface opposite to that opposite the fastening surface.

Die Befestigungsfläche kann auch zur Aufnahme des Klebstoffs vorgesehen sein.The attachment surface may also be provided for receiving the adhesive.

Nach einer Ausführungsform ist ein stoßdämpfendes Material gegenüber dem steifen Abschnitt oder dem steifen Teil auf der entgegengesetzten Oberfläche des Films, welcher diesen Abschnitt oder dieses Teil trägt, angeordnet, wobei das stoßdämpfende Material fest mit der Befestigungsfläche verbunden ist und dazu bestimmt ist, an der Scheibe befestigt zu werden.In one embodiment, a shock-absorbing material is disposed opposite the rigid portion or the rigid portion on the opposite surface of the film carrying that portion or portion, the shock-absorbing material being fixedly connected to the attachment surface and destined to the disk to be attached.

Das stoßdämpfende Material kann des Weiteren Befestigungsmittel bilden, wenn es zum Beispiel ein doppelseitiges Klebeband umfasst.The shock-absorbing material may further form fasteners when it includes, for example, a double-sided adhesive tape.

Nach einer weiteren Ausführungsform ist ein stoßdämpfendes Material gegenüber dem steifen Abschnitt oder dem steifen Teil und auf der Oberfläche des Films, welcher diesen Abschnitt oder dieses Teil trägt, angeordnet.According to a further embodiment, a shock-absorbing material is arranged opposite to the rigid portion or the rigid part and on the surface of the film carrying this portion or part.

Nach einer weiteren Charakteristik ist der steife Abschnitt oder das steife Teil dicker als der Film und ist mit einem elektrischen Leiter, der außerhalb der Scheibe geführt wird, verbunden oder soll damit verbunden werden.According to another characteristic, the rigid portion or the rigid portion is thicker than the film and is provided with an electrical conductor outside the Disc is connected, connected or is to be connected to it.

Vorzugsweise ist der steife Abschnitt oder das steife Teil Metall, wie Kupfer enthält.Preferably, the rigid portion or member is metal, such as copper.

Nach einer Ausführungsform des Films ist dieser derart gefaltet, dass er einen Umschlag ausbildet, der eine innere Aufnahmeunterkunft umfasst, um die Zwischenmittel, wie etwa ein stoßdämpfendes Material, unterzubringen.In one embodiment of the film, it is folded to form an envelope comprising an inner containment housing to accommodate the intermediate means, such as a shock-absorbing material.

Vorteilhafterweise weist mindestens die Oberfläche des Films, der dazu bestimmt ist, mit der Scheibe in Kontakt zu sein, eine polygonale Form mit runden Ecken auf, was das Risiko des Durchzugs von Spannungen ferner minimiert.Advantageously, at least the surface of the film intended to be in contact with the disk has a polygonal shape with rounded corners, further minimizing the risk of stress traction.

Das Verbindungselement der Erfindung wird daher vorteilhafterweise in Scheiben, vorzugsweise in Heizscheiben oder mit Antenne benutzt, sowie in Gebäuden oder in Fortbewegungsmaschinen, insbesondere Automobilen oder Eisenbahnen oder Flugzeugen oder auch Seefahrzeugen.The connecting element of the invention is therefore advantageously used in slices, preferably in heating disks or with an antenna, and in buildings or in locomotion machines, in particular automobiles or railways or aircraft or even sea vehicles.

Wenn das oben beschriebene Verbindungselement nach der Erfindung somit zur Montage bereit und daher leicht umzusetzen ist, ist es ebenfalls möglich, alle Bestandteile, welche das Verbindungselement bereitstellen, getrennt auf der Scheibe zu montieren.Thus, if the connecting element according to the invention described above is ready for assembly and therefore easy to implement, it is also possible to mount all the components which provide the connecting element separately on the pane.

Außerdem betrifft die Erfindung eine Scheibe, umfassend mindestens einen Glasfilm, mindestens eine elektrisch leitende Komponente, die auf dem Glasfilm abgelagert ist, und mindestens ein elektrisches Verbindungselement, das einen elektrisch leitenden Körper umfasst, der mit der Komponente verbunden ist, dadurch gekennzeichnet, dass der elektrisch leitende Körper mindestens einen elektrisch leitenden Film umfasst, der eine Dicke zwischen 1 und 500 µm aufweist, wobei der Film mindestens eine elektrische Anschlussfläche umfasst, die mit der Komponente in Kontakt ist, und mindestens eine Befestigungsfläche, die fest mit der Scheibe verbunden ist, und dadurch, dass der Körper einen steifen Abschnitt umfasst, der mit dem Film verbunden ist, oder dadurch, dass ein elektrisch leitendes steifes Teil auf dem Film angeschlossen ist, wobei Zwischenmittel derart mit dem Körper in Verbindung stehen, dass der steife Abschnitt oder das steife Teil nicht direkt mit der Scheibe über die einzige Dicke des Films in Kontakt ist.Moreover, the invention relates to a pane comprising at least one glass film, at least one electrically conductive component deposited on the glass film, and at least one electrical connection element comprising an electrically conductive body connected to the component, characterized in that the electrically conductive body comprises at least one electrically conductive film having a Thickness between 1 and 500 microns, wherein the film comprises at least one electrical connection surface, which is in contact with the component, and at least one mounting surface, which is fixedly connected to the disc, and in that the body comprises a rigid portion which is connected to the film, or in that an electrically conductive rigid part is connected to the film, wherein intermediate means are so in communication with the body, that the rigid portion or the rigid part is not directly with the disc over the single thickness of the film is in contact.

Gemäß einer bevorzugten Ausführungsform sind die Zwischenmittel aus einem stofdämpfenden Material ausgebildet, das durch eine seiner Oberflächen auf der Befestigungsfläche des Films und durch seine entgegengesetzte Oberfläche fest mit der Scheibe verbunden ist.According to a preferred embodiment, the intermediate means are formed of a cushioning material which is fixedly connected to the disc by one of its surfaces on the mounting surface of the film and by its opposite surface.

Schließlich betrifft die Erfindung auch ein Verfahren zur Montage eines wie oben beschriebenen Verbindungselements, wobei die Zwischenmittel aus einem stoßdämpfenden Material ausgebildet sind, das auf der Befestigungsfläche des elektrisch leitenden Films des Körpers des Verbindungselements angeschlossen ist,

  • Befestigen des stoßdämpfenden Materials auf der Scheibe, wie etwa durch Kleben, wobei die elektrische Anschlussfläche des Films gegen die Komponente gestellt wird,
  • Löten des Films an die Komponente der Scheibe oder Schweißen oder Kleben des Films, der zuvor mit der Oberfläche des fest zu verbindenden Films, der zu löten ist, der Lötung bzw. des elektrisch leitenden Klebers in Verbindung gebracht wurde,
  • und Schweißen des steifen Teils, das zur Verbindung in Richtung der Außenseite der Scheibe bestimmt ist, wenn dieses nicht Teil des Verbindungselements ist oder noch nicht angeschlossen wurde, an den Film gegenüber dem stoßdämpfenden Material.
Finally, the invention also relates to a method for assembling a connecting element as described above, wherein the intermediate means are formed of a shock-absorbing material which is connected to the mounting surface of the electrically conductive film of the body of the connecting element,
  • Attaching the shock absorbing material to the disc, such as by gluing, placing the electrical pad of the film against the component;

  • and welding the rigid member intended for connection towards the outside of the disk, if not part of the connector or not yet connected, to the film opposite the shock-absorbing material.

Die Figuren sind zur Erleichterung des Lesens nicht maßstabgetreu.The figures are not to scale for ease of reading.

Figur 1 zeigt eine Scheibe 1, umfassend mindestens einen Glasfilm 10, mindestens eine elektrisch leitende Komponente 11, zum Beispiel ein leitendes Band auf Basis von Silber, das die elektrische Verbindung einer leitenden Struktur, wie etwa mehrere Heizdrähte 12 oder eine in die Scheibe integrierte Antenne zusammenfasst. FIG. 1 shows a disc 1, comprising at least one glass film 10, at least one electrically conductive component 11, for example, a conductive tape Base of silver, which summarizes the electrical connection of a conductive structure, such as several heating wires 12 or an integrated into the disc antenna.

Ein elektrisches Verbindungselement 2 nach der Erfindung ist auf der Scheibe angeordnet, indem es elektrisch mit der Komponente 11, zum Beispiel im Hinblick auf seine Stromversorgung, verbunden wird.An electrical connection element 2 according to the invention is arranged on the pane by being electrically connected to the component 11, for example with regard to its power supply.

Wie schematisch in Figur 2 und 3 dargestellt, umfasst das Verbindungselement 2 nach der Erfindung einen elektrisch leitenden Körper 20, der einen elektrisch leitenden biegsamen Film 21 und einen elektrisch leitenden steifen Abschnitt 22 oder ein elektrisch leitendes steifes Teil 3, das bezüglich des Körpers 20, des Abschnitts 22 oder des Teils 3, welches mit dem Film 21 verbunden ist, angeschlossen ist oder dazu bestimmt ist, daran angeschlossen zu werden, umfasst.As schematically in FIGS. 2 and 3 1, the connecting element 2 according to the invention comprises an electrically conductive body 20 comprising an electrically conductive flexible film 21 and an electrically conductive rigid portion 22 or an electrically conductive rigid portion 3 relative to the body 20, the portion 22 or the part 3 which is connected to, connected to or intended to be connected to the film 21.

Der Abschnitt 22 und der Film 21 bilden im Ausführungsbeispiel von Figur 2 eine Monoblockstruktur, wobei der Abschnitt 22 dicker als der Film 21 ist.The section 22 and the film 21 form in the embodiment of FIG. 2 a monoblock structure wherein the portion 22 is thicker than the film 21.

Im anderen Beispiel von Figur 3 wird das Teil 3 gegen den Film 21 angeschlossen, wie etwa mittels Schweißen, crimpen, löten, nieten, clinchen.In the other example of FIG. 3 the part 3 is connected against the film 21, such as by means of welding, crimping, soldering, riveting, clinching.

Der Film 21 ist dazu bestimmt, mit der Komponente 11 der Scheibe über eine elektrische Anschlussfläche 21a verbunden zu werden, wohingegen der Abschnitt 22 oder das Teil 3 dazu bestimmt ist, mit einem elektrischen Versorgungsleiter 4 in Richtung der Außenseite der Scheibe verbunden zu werden. Dieser Leiter 4 kann sich außerhalb des Verbindungselementes 2 befinden und lässt sich schließlich nach der Befestigung des Verbindungselements an der Scheibe anschließen oder ist vorzugsweise Teil des Verbindungselements 2.The film 21 is intended to be connected to the component 11 of the disk via an electrical connection surface 21a, whereas the portion 22 or the part 3 is intended to be connected to an electrical supply conductor 4 towards the outside of the disk. This conductor 4 may be located outside of the connecting element 2 and may finally be connected after the attachment of the connecting element to the disc or is preferably part of the connecting element. 2

Das Verbindungselement 2 ist dazu bestimmt, über eine Befestigungsfläche 21b des Films 21, der von der elektrischen Anschlussfläche 21a getrennt oder nicht getrennt sein kann, an der Scheibe befestigt zu werden.The connecting element 2 is intended to be secured to the disc via a fixing surface 21b of the film 21, which may or may not be separate from the electrical connection surface 21a.

Der elektrisch leitende Film 21 ist metallisch. Er weist eine Dicke zwischen 1 und 500 µm, insbesondere zwischen 1 und 200 µm und vorzugsweise zwischen 1 und 100 µm auf. Seine geringe Dicke ermöglicht, dass er biegsam und somit bei Bedarf leicht zu falten ist, um die Anordnung des Verbindungselements auf der Scheibe anzupassen. Und vornehmlich ermöglicht er, dass keine starken Spannungen auf das Glas übertragen werden.The electrically conductive film 21 is metallic. It has a thickness of between 1 and 500 μm, in particular between 1 and 200 μm, and preferably between 1 and 100 μm. Its small thickness allows it to be pliable and thus easy to fold when needed to accommodate the arrangement of the fastener on the disc. And most importantly, it does not allow strong tensions to be transmitted to the glass.

Der Film 21 besteht aus einer oder mehreren Metallschichten, wie etwa einem Laminatverbund mit zum Beispiel einer oder zwei Schichten aus einer Silberlegierung, insbesondere Zinn, und mindestens einer Zwischenschicht aus Kupfer, einer Silberlegierungsschicht, die dazu bestimmt ist, auf die Komponente 11 gelötet zu werden.The film 21 consists of one or more metal layers, such as a laminate composite with, for example, one or two layers of a silver alloy, in particular tin, and at least one intermediate layer of copper, a silver alloy layer, which is intended to be soldered onto the component 11 ,

Der steife Abschnitt 22 oder das steife Teil 3 weist eine viel größere Dicke auf als der Film 21, um für den Leiter 4 eine ausreichend steife Auflagefläche zu bilden. Der Abschnitt 22 oder das Teil 3 ist vorzugsweise aus Kupfer und weist eine Dicke von zum Beispiel 800 µm auf.The rigid portion 22 or the rigid portion 3 has a much greater thickness than the film 21 to form a sufficiently rigid support surface for the conductor 4. The section 22 or the part 3 is preferably made of copper and has a thickness of, for example, 800 μm.

Figuren 4 bis 7 stellen beispielhaft unterschiedliche Ausführungsvarianten von Verbindungselementen dar. FIGS. 4 to 7 represent exemplified different embodiments of fasteners.

Figuren 4 und 5 stellen Körper 20 eines Verbindungselements mit ebener parallelepipedförmiger Form dar, während dasjenige aus Figur 6 scheibenförmig ist. Figur 7 zeigt den Körper 20 in Form eines parallelepipedförmigen Umschlags. FIGS. 4 and 5 represent body 20 of a connecting element with a plane parallelepiped-shaped form, while that of FIG. 6 is disc-shaped. FIG. 7 shows the body 20 in the form of a parallelepipedic envelope.

In Figuren 5 und 7 ist ersichtlich, dass der Leiter 4 Teil des Verbindungselements 2 ist, zum Beispiel handelt es sich um einen Multifilamentleiter 41 aus Kupfer, der in einem zylindrischen oder flachen Isolierschlauch 42 angeordnet ist, wobei der Leiter ein Ende 43, das an das Teil 3 des elektrisch leitenden Körpers 20 geschweißt ist, und ein entgegengesetztes freies Ende 44, zum Beispiel der Art zum Aufstecken, aufweist.In FIGS. 5 and 7 It can be seen that the conductor 4 is part of the connecting element 2, for example, it is a copper multifilament conductor 41, which is arranged in a cylindrical or flat insulating 42, wherein the conductor has an end 43 which is connected to the part 3 of the electrically conductive body 20 is welded, and an opposite free end 44, for example, the type of attachment has.

In Figur 4 ist der nicht dargestellte Leiter 4 hingegen nicht Teil des Verbindungselements 2, zum Beispiel wird er zu einem späteren Zeitpunkt nach einer mechanischen Schnittstelle durch gegenseitige Zusammenarbeit von Formen angeschlossen.In FIG. 4 on the other hand, the conductor 4, not shown, is not part of the connecting element 2, for example it is connected at a later time to a mechanical interface by mutual cooperation of molds.

In Figur 6 wird der Leiter 4 ebenfalls hinsichtlich Teil 3 angeschlossen, wobei er dagegen lediglich durch Druck darauf aufgetragen wird, wobei das Ende 45 des Leiters die Form eines Federblatts aufweist.In FIG. 6 the conductor 4 is also connected with regard to part 3, whereas it is merely applied thereto by pressure, the end 45 of the conductor being in the form of a spring leaf.

Der Abschnitt 22 oder das steife Teil 3 bilden den Versorgungseingang des Verbindungselements 2, wobei der Strom vom Leiter 4 kommt, wohingegen der Film 21 den Versorgungsausgang des Verbindungselements bildet, um die Stromversorgung der Komponente 11 der Scheibe zu gewährleisten.The portion 22 or the rigid part 3 forms the supply input of the connecting element 2, the current coming from the conductor 4, whereas the film 21 forms the supply output of the connecting element to ensure the power supply of the component 11 of the disc.

Der elektrische Anschluss zwischen dem Verbindungselement 2 und der Komponente 11 der Scheibe ist dazu bestimmt, mit einem einzelnen Kontakt zwischen dem Film 21 und der Komponente 11 an einer elektrischen Anschlussfläche 21a des Films 21 verwirklicht zu werden. Dieser Anschluss wird durch Löten, Schweißen oder selbst Kleben mithilfe eines elektrisch leitenden Klebers der Anschlussfläche 21a erreicht.The electrical connection between the connecting element 2 and the component 11 of the disc is intended to be realized with a single contact between the film 21 and the component 11 on an electrical connection surface 21 a of the film 21. This connection is achieved by soldering, welding or even bonding by means of an electrically conductive adhesive of the connection surface 21a.

Nach der Erfindung ist das Verbindungselement 2 dazu bestimmt, mechanisch auch mittels des Metallfilms 21 an einer Befestigungsfläche 21b an der Scheibe befestigt zu werden, wobei der Metallfilm an sich einen Träger zur Befestigung bildet.According to the invention, the connecting element 2 is intended to be fixed mechanically to the disc also by means of the metal film 21 on a fixing surface 21b, the metal film itself forming a support for attachment.

Da der Metallfilm 21 zugleich den elektrischen Anschluss und die Befestigung des Verbindungselements gewährleistet und mit dem Abschnitt 22 oder dem Teil 3 verbunden ist, ist es nach der Erfindung wichtig, dass der steife Abschnitt 22 oder das steife Teil 3 nicht mit der Scheibe über die einzige Dicke der Folie 21 in direktem Kontakt sind. Tatsächlich verhindert diese Charakteristik, dass die Wärmespannungen, welche im steifen Abschnitt 22 oder dem Teil 3 erzeugt wurden, sich nicht direkt in der Scheibe verteilen.Since the metal film 21 at the same time ensures the electrical connection and the attachment of the connecting element and is connected to the portion 22 or the part 3, it is important according to the invention that the rigid portion 22 or the rigid part 3 not with the disc on the single Thickness of the film 21 are in direct contact. In fact, this characteristic prevents the thermal stresses generated in the rigid portion 22 or part 3 from being distributed directly in the disk.

Nach der Erfindung umfasst das Verbindungselement Zwischenmittel, insbesondere stoßdämpfende Zwischenmittel, die gegen eine der Oberflächen des Films 21, und hinsichtlich dieses Abschnitts 22 oder dieses Teils 3, angeordnet sind oder angeordnet werden sollen. Somit ist der steife Abschnitt 22 oder das Teil 3 nicht dazu bestimmt, über die Dicke des einzigen Metallfilms 21, welcher dazu bestimmt ist, auf der Scheibe befestigt zu werden, mit der Scheibe in direktem Kontakt zu sein.According to the invention, the connecting element comprises intermediate means, in particular shock-absorbing intermediate means, which are arranged or should be arranged against one of the surfaces of the film 21, and with respect to this portion 22 or this part 3. Thus, the rigid portion 22 or portion 3 is not intended to be in direct contact with the disk through the thickness of the single metal film 21 which is intended to be secured to the disk.

Die Zwischenmittel sind mit einem stoßdämpfenden Material 5 oder einer Luftschicht 6 gebildet.The intermediate means are formed with a shock-absorbing material 5 or an air layer 6.

Ausführungsbeispiele mit einer Luftschicht 6 sind jedoch nicht Teil der Erfindung.However, embodiments with an air layer 6 are not part of the invention.

Die Dicke der Zwischenmittel liegt vielmehr zwischen 1 und 2500 µm.The thickness of the intermediate means is rather between 1 and 2500 microns.

Das stoßdämpfende Material 5 weist zum Beispiel die Form eines Polymerschaums auf, der klebend ist, um mit dem Metallfilm 21 fest verbunden zu werden. Es kann sich auch um ein standardmäßiges doppelseitiges Klebeband handeln, dessen geläufige Dicke zwischen 0,05 mm und 2,3 mm liegt.The shock-absorbing material 5 has, for example, the shape of a polymer foam, which is adhesive to be firmly bonded to the metal film 21. It can also be a standard double sided tape act whose common thickness is between 0.05 mm and 2.3 mm.

Es können verschiedene Ausführungsvarianten zur Anordnung des stoßdämpfenden Materials 5 oder der Luftschicht 6 danach, ob die elektrische Anschlussfläche 21a von der Befestigungsfläche 21b getrennt ist oder nicht, unterschieden werden.Various embodiments for disposing the shock-absorbing material 5 or the air layer 6 according to whether or not the electrical connection surface 21a is separated from the attachment surface 21b can be discriminated.

Ausführungsvarianten mit Luftschicht sind jedoch nicht Teil der Erfindung.Embodiments with air layer are not part of the invention.

Das stoßdämpfende Material kann bevorzugt werden, wenn der Körper 20 eine ebene parallelepipedförmige Form aufweist (Figur 4 und 5). Das Material wird auf der Oberfläche entgegengesetzt zum Film 21 und hinsichtlich des Teils 3 an der Befestigungsfläche 21b des Films 21 angeordnet, um seinerseits dem Verbindungselement eine Befestigungsfläche bereitzustellen.The shock-absorbing material may be preferred when the body 20 has a plane parallelepiped shape ( FIGS. 4 and 5 ). The material is placed on the surface opposite to the film 21 and, with respect to the part 3, on the mounting surface 21b of the film 21, to provide the fastener with a mounting surface.

Auf Figuren 8 und 9 sind zwei Varianten von Schnittansichten der Figur 6 dargestellt. Wie in Figur 8 gezeigt, ist es möglich, ein stoßdämpfendes Material 5 vorzusehen, das auf der Oberfläche gegenüber dem Film 21 und hinsichtlich des Teils 3 in der Mitte des Kreises, der die Befestigungsfläche 21b bildet, angeordnet ist, um seinerseits mittels Verbindungsmitteln 7 an der Scheibe befestigt zu werden. Die Fläche 21a des elektrischen Anschlusses ist ihrerseits auf der Peripherie des Kreises in einem Ring angeordnet, um mit der Komponente 11 der Scheibe, zum Beispiel mittels einer Lötung 8, verbunden zu werden.On FIGS. 8 and 9 are two variants of sectional views of the FIG. 6 shown. As in FIG. 8 As shown, it is possible to provide a shock absorbing material 5 which is disposed on the surface opposite to the film 21 and with respect to the part 3 in the center of the circle constituting the mounting surface 21b, to be fastened to the disk by means of connecting means 7 become. The face 21a of the electrical terminal is in turn disposed on the periphery of the circle in a ring to be connected to the component 11 of the disc, for example by means of soldering 8.

In Figur 9 wird kein stoßdämpfendes Material benutzt, wobei eine Luftschicht 6 den Nicht-Kontakt des Teils 3 mit der Scheibe bereitstellt. Die Dicke der Lötung 8 der Anschlussfläche 21a gegen die Komponente 11 der Scheibe, wobei diese Fläche als Ring auf der einzigen Peripherie des Kreises und nicht hinsichtlich des Teils 3 vorgesehen ist und die Befestigungsfläche 21b bildet, reicht aus, um die entsprechende Dicke der Luftschicht 6 zwischen dem Film 21 und der Scheibe hinsichtlich des Teils 3 bereitzustellen.In FIG. 9 no shock absorbing material is used, with an air layer 6 providing non-contact of the part 3 with the disk. The thickness of the solder 8 of the pad 21a against the component 11 of the disc, which surface is provided as a ring on the single periphery of the circle and not with respect to the part 3 and forms the mounting surface 21b, is sufficient to provide the appropriate thickness of the air layer 6 between the film 21 and the disc with respect to the part 3 to provide.

Für Figur 7 besteht der Körper 20 aus einem Umschlag, der in seinem Inneren eine Aufnahmeunterkunft 23 bereitstellt, wobei die Anschlussfläche 21a die Befestigungsfläche 21b bildet, die dazu bestimmt ist, gegen die Komponente 11 der Scheibe geschweißt oder gelötet zu werden. Das Teil 3 ist mit dem Umschlag 21 in Kontakt, jedoch kann das Teil 3, da die Aufnahmeunterkunft 23, in welcher sich das stoßdämpfende Material 5 und das Teil 3 befindet, das gegenüber diesem stoßdämpfenden Material ist, nicht mit der Scheibe nach der einzigen Dicke des Films 21 in Kontakt sein.For FIG. 7 The body 20 consists of an envelope which provides a housing for accommodation 23 inside, the terminal surface 21a forming the attachment surface 21b intended to be welded or soldered against the component 11 of the disc. The part 3 is in contact with the envelope 21, however, since the accommodating accommodation 23 in which the shock absorbing material 5 and the part 3 are located, the part 3 can not be the single thickness one with respect to this shock absorbing material the film 21 in contact.

Das Material 5, das vorzugsweise auf einem Kunststoffmaterial basiert, weist die Eigenschaft auf, aufgrund seines Kontaktes mit dem Film 21, der sich während der Schweißvorgänge erwärmen kann, wärmebeständig zu sein.The material 5, which is preferably based on a plastic material, has the property of being heat-resistant due to its contact with the film 21, which may heat up during the welding operations.

Figur 10 stellt eine Ausführungsvariante im Schnitt der Figur 7 dar, wobei der Umschlag des Körpers 20 nach seiner größten Ausdehnung nicht vollkommen geschlossen ist, sondern eine U-Form aufweist. Das stoßdämpfende Material 5 ist in der Aufnahmeunterkunft 23 angeordnet, die durch die Vertiefung von U ausgebildet ist, und das Teil 3 wird direkt über das Material 5 gesetzt, wobei die elektrische Verbindung zwischen dem Film 21 und dem Teil 3 seitlich mittels der Flügel von U stattfindet. FIG. 10 represents a variant in the section of FIG. 7 is, wherein the envelope of the body 20 is not completely closed after its greatest extent, but has a U-shape. The shock absorbing material 5 is disposed in the accommodation housing 23 formed by the recess of U, and the part 3 is placed directly over the material 5, the electrical connection between the film 21 and the part 3 being laterally by means of the wings of U takes place.

Figuren 11 und 12 zeigen ferner zwei weitere Varianten im Schnitt eines Verbindungselements, dessen Film 21 die Form eines halb geschlossenen Umschlags aufweist, wobei die Befestigung des Elements über das stoßdämpfende Material 5 und Verbindungsmittel 7 für Figur 11 stattfindet, während sie durch die direkte feste Verbindung des Films 21 mit der Lötung 8 für Figur 12 erreicht wird. FIGS. 11 and 12 also show two further variants in the section of a connecting element whose film 21 has the shape of a semi-closed envelope, the attachment of the element via the shock-absorbing material 5 and connecting means 7 for FIG. 11 takes place while passing through the direct solid connection of the film 21 with the solder 8 for FIG. 12 is reached.

Wenn die Befestigungsfläche 21b die elektrische Anschlussfläche 21a bildet, wird die Befestigung des Verbindungselements durch Schweißen, Löten oder Kleben mittels elektrisch leitendem Kleber des Films 21 gegen die Komponente 11 der Scheibe durchgeführt.When the mounting surface 21b forms the electrical connection surface 21a, the attachment of the connection element is performed by welding, soldering or gluing by means of electrically conductive adhesive of the film 21 against the component 11 of the disk.

Wenn die Befestigungsfläche 21b von der elektrischen Anschlussfläche 21a getrennt ist, wird die Befestigung des Verbindungselements mittels Verbindungsmitteln 7 durchgeführt, die auf dem stoßdämpfenden Material 5 angeordnet sein können oder durch dieses stoßdämpfende Material gebildet sein können, wobei das Material gegen die Befestigungsfläche 21b des Films 21 angeschlossen ist oder die Verbindungsmittel direkt auf der Befestigungsfläche des Films angeordnet sind.When the attachment surface 21b is separated from the electrical connection surface 21a, the attachment of the connection element is performed by connecting means 7 which may be disposed on the shock absorbing material 5 or formed by this shock absorbing material, the material bearing against the attachment surface 21b of the film 21 is connected or the connecting means are arranged directly on the mounting surface of the film.
