Description
Die Erfindung betrifft ein elektrisches Kontaktelement und ein Verfahren zur Herstellung eines elektrischen Kontaktelementes.The The invention relates to an electrical contact element and a method for producing an electrical contact element.
In neuester Zeit werden für Batterieleitungen in Kraftfahrzeugen vermehrt Aluminiumkabel verwendet. Insbesondere hat sich die Verwendung von Aluminiumflachbandleitern als vorteilhaft herausgestellt. Die B+ Leitung wird bevorzugt im Hauptstrang als Aluminiumflachbandleiter geführt. Dieser Aluminiumflachbandleiter wird vorzugsweise am Unterboden oder in der Mittelkonsole eines Kraftfahrzeugs geführt, und Abgänge zu Verbrauchen zweigen von dieser Aluminiumflachbandleitung ab.In latest time will be for Battery cables in motor vehicles increasingly used aluminum cables. In particular, the use of aluminum flat ribbon conductors has proved to be advantageous. The B + line is preferred in Main line led as aluminum flat strip conductor. This aluminum flat ribbon conductor is preferably on the underbody or in the center console of a Motor vehicle, and disposals To consume branches off this aluminum flat ribbon cable.
Die Kontaktierung von Abgriffen an Aluminiumleitungen ist jedoch problematisch, da sich auf der Oberfläche von Aluminiumleitungen eine Aluminiumoxidschicht bildet. Diese Aluminiumoxidschicht verhindert eine gute elektrische Kontaktierung mit Anschlussleitungen.The Contacting taps on aluminum pipes is problematic, as it is on the surface of aluminum lines forms an aluminum oxide layer. This aluminum oxide layer prevents good electrical contact with connection cables.
Darüber hinaus ist es in Feuchträumen von Kraftfahrzeugen von Nachteil, wenn eine Kontaktfläche zwischen einem Aluminiumflachbandleiter und einer aus einem anderen Metall gebildeten Anschlussleitung Feuchtigkeit ausgesetzt ist. Die Feuchtigkeit führt zu verstärkter Korrosion, insbesondere auch aufgrund unterschiedlicher Elektronegativitäten der miteinander verbundenen Metalle.Furthermore it is in wet rooms of motor vehicles of disadvantage when a contact surface between an aluminum ribbon conductor and one of another metal formed connecting line is exposed to moisture. The humidity leads to reinforced Corrosion, in particular due to different electronegativities of interconnected metals.
Daher lag der Erfindung die Aufgabe zugrunde, eine Kontaktierung einer Batterieleitung mit hoher elektrischer Güte zur Verfügung zu stellen, wobei die Kontaktierung stabil gegenüber Umwelteinflüssen ist.Therefore The invention was based on the object, a contacting of a To provide battery line with high electrical quality, the contacting stable opposite environmental influences is.
Diese Aufgabe wird gemäß eines Gegenstandes durch ein Verfahren zur Herstellung eines elektrischen Kontaktelements gelöst, bei dem ein Aluminium-Flachteil mit einem aus Übergangsmetall gebildeten Flachteil stoffschlüssig verbunden wird, und bei dem eine Nahtstelle zwischen dem Aluminium und dem Übergangsmetall isoliert wird.These Task is done according to a Object by a process for producing an electrical Contact element solved, in which an aluminum flat part with a formed of transition metal flat part cohesively and where there is an interface between the aluminum and the transition metal is isolated.
Das entstehende Kontaktelement weist zwei Anschlussfahnen aus unterschiedlichen Metallen auf. Eine erste Anschlussfahne ist aus Aluminium gebildet und eine zweite Anschlussfahne aus einem Übergangsmetall, vorzugsweise Kupfer oder einer Legierung davon. Die Anschlussfahne aus Aluminium kann besonders einfach mit einem Aluminiumleiter, bevorzugt mit einer Aluminiumflachbandleitung als B+ Leitung kontaktiert werden. Da das Kontaktelement aus Flachteilen gebildet ist, eignet sich dieses besonders gut für die Kontaktierung mit einer Flachbandleitung, die beispielsweise als Batteriehauptleitung genutzt wird. Die zweite, aus Übergangsmetall gebildete Anschlussfahne hat sehr gute elektrische und mechanische Eigenschaften und ermöglicht eine leichte Kontaktierung mit einer Anschlussleitung aus Kupfer. Um Korrosionen der Nahtstelle zwischen Aluminium und Übergangsmetall zu verhindern, wird vorgeschlagen, diese Nahtstelle zu isolieren.The resulting contact element has two terminal lugs of different Metals on. A first connection lug is made of aluminum and a second terminal lug of a transition metal, preferably Copper or an alloy thereof. The connecting lug made of aluminum Can be particularly easy with an aluminum conductor, preferably with an aluminum ribbon cable to be contacted as B + line. Since the contact element is formed from flat parts, is suitable this is especially good for the contacting with a ribbon cable, for example is used as a battery main line. The second, made of transition metal Terminal lug has very good electrical and mechanical properties and allows a slight contact with a connecting cable made of copper. To corrosion of the interface between aluminum and transition metal It is proposed to isolate this interface.
Ein kontinuierlicher Herstellungsprozess, insbesondere bei dem die Flachteile erheblich größer sind, als die daraus zu formenden Kontaktelemente, wird dadurch zur Verfügung gestellt, dass aus den miteinander stoffschlüssig verbundenen Flachteilen das Kontaktelement quaderförmig herausgetrennt wird. So kann beispielsweise in einem kontinuierlichen Prozess die stoffschlüssige Verbindung zwischen den Flachteilen hergestellt werden und im unmittelbaren Anschluss an die stoffschlüssige Verbindung zwischen den Flachteilen das Kontaktelement gebildet werden.One continuous manufacturing process, especially where the flat parts are considerably larger, as the contact elements to be formed therefrom, is thereby provided that from the cohesively connected flat parts the Contact element cuboid is cut out. For example, in a continuous Process the cohesive Connection between the flat parts are made and in the immediate Connection to the cohesive Connection between the flat parts formed the contact element become.
Bevorzugt ist dabei, dass das Aluminium-Flachteil und/oder das aus Übergangsmetall gebildete Flachteil als Bandware bereitgestellt wird. So können die als Bandware zur Verfügung gestellten Vormaterialien in einfacher Weise für die Herstellung des erfindungsgemäßen Kontaktelementes verwendet werden. Bevorzugt ist die Verwendung von Bändern aus Aluminium und/oder Übergangsmetall, die eine Breite von 1–10cm und einer Stärke von 1–50mm haben.Prefers is doing that the aluminum flat part and / or the transition metal formed flat part is provided as a tape product. So can the as a bandware available Asked materials in a simple manner for the production of the contact element according to the invention be used. The use of bands is preferred Aluminum and / or transition metal, the width of 1-10cm and a strength from 1-50mm to have.
Besonders bevorzugt ist die Verwendung von Bändern, die von einem Coil abgewickelt werden. In diesem Falle lassen sich in einem Zwischenschritt stoffschlüssig miteinander verbundene Bänder aus Aluminium und Übergangsmetall von einer Länge bis zu mehreren hundert Metern, bevorzugt 200m, herstellen. Die von einem Coil abgewickelten Flachteile werden kontinuierlich stoffschlüssig miteinander verbunden, und können danach erneut aufgecoilt werden, oder dem weiteren Verarbeitungsprozess zugeführt werden.Especially preferred is the use of tapes unwound from a coil become. In this case, can be materially interlocked with each other in an intermediate step connected bands off Aluminum and transition metal of a length up to several hundred meters, preferably 200m. The flat parts unwound from a coil are continuously bonded together and can be recharged afterwards, or be fed to the further processing process.
Gute mechanische Eigenschaften weisen Bänder auf, die gewalzt oder gezogen sind. Daher ist bevorzugt, dass das Aluminium-Flachteil und/oder das aus Übergangsmetall gebildete Flachteil aus gewalztem oder gezogenem Halbzeug bereitgestellt wird.Quality Mechanical properties include tapes rolled or are drawn. Therefore, it is preferable that the aluminum flat part and / or the transition metal formed flat part of rolled or drawn semi-finished product is provided.
Zur Herstellung eines flachen Kontaktelementes mit zwei Anschlussfahnen wird vorgeschlagen, dass die Flachteile entlang ihrer langen, schmalen Seite stoffschlüssig miteinander verbunden werden. So ist es möglich, dass die von einem Coil abgewickelten Bänder über geeignete Führungen mit ihren schmalen Seitenkanten gegeneinander gedrückt werden und kontinuierlich miteinander stoffschlüssig verbunden werden. Für die kontinuierliche stoffschlüssige Verbindung eignen sich bevorzugt Reibschweißen, Multi-Orbital-Schweißen, Rührreibschweißen oder Elektronenstrahlschweißen. Andere Schweißverfahren eignen sich jedoch ebenfalls für die Kontaktierung der Flachteile miteinander.To produce a flat contact element with two terminal lugs, it is proposed that the flat parts be joined together in a material-locking manner along their long, narrow side. Thus, it is possible that the unwound from a coil tapes are pressed against each other via suitable guides with their narrow side edges and continuously connected to one another cohesively. For the continuous cohesive connection are preferably friction welding, multi-orbital welding, friction stir welding or electron beam welding. However, other welding methods are also suitable for contacting the flat parts with each other.
Während des kontinuierlichen Herstellungsprozesses kann, nachdem die Flachteile kontinuierlich miteinander stoffschlüssig verbunden wurden, das Kontaktelement aus den miteinander verbundenen Bändern herausgetrennt werden. Hierzu eignen sich besonders bevorzugt Stanzen, Sägen, Erodieren, Laserschneiden, Wasserstrahlschneiden. Mit Hilfe dieser spanenden oder spanlosen Trennverfahren lassen sich Kontaktelemente geeigneter Größe aus den Bändern heraustrennen. Bei der Herstellung der Bänder aus von Coils abgewickelten Bändern können so in einem kontinuierlichen Prozess mehrere hundert bis mehre tausend einzelne Kontaktelemente in einem kontinuierlichen Prozess nacheinander hergestellt werden. Die Bänder werden von Coils abgewickelt, stoffschlüssig miteinander verbunden, und die Kontaktelemente werden herausgetrennt. Kontaktelemente mit Kantenlängen zwischen 1 und 5cm sind besonders bevorzugt.During the continuous manufacturing process can after the flat parts were continuously connected to each other cohesively, the Contact element to be separated from the interconnected bands. Particularly suitable for this purpose are punching, sawing, eroding, Laser cutting, water jet cutting. With the help of this cutting or non-cutting separation process, contact elements can be more suitable Size out of the bands Cut out. In the production of tapes unwound from coils Bands can do that in a continuous process several hundred to several thousand individual contact elements in a continuous process in succession getting produced. The bands are unwound from coils, firmly bonded together, and the contact elements are cut out. Contact elements with edge lengths between 1 and 5cm are particularly preferred.
Während oder nach dem Heraustrennen der Kontaktelemente ist es notwendig, die Nahtstelle zwischen Aluminium- und Übergangsmetall gegen Korrosion zu schützen. Daher wird vorgeschlagen, dass die Nahtstelle des Kontaktelementes zwischen dem Aluminium und dem Übergangsmetall mittels Kunststoff umspritzt wird. Diese Kunststoffumspritzung kann unmittelbar nach dem Heraustrennen des Kontaktelementes aus den Bändern erfolgen. Da die gesamte Verarbeitung in einem kontinuierlichen Prozess erfolgt, wird vermieden, dass die Nahtstelle über einen längeren Zeitraum Umwelteinflüssen ausgesetzt ist.While or After removing the contact elements, it is necessary to Interface between aluminum and transition metal against corrosion to protect. Therefore, it is suggested that the interface of the contact element between the aluminum and the transition metal is encapsulated by plastic. This plastic extrusion can immediately after the separation of the contact element from the bands respectively. Because the whole processing in a continuous Process, it is avoided that the interface over a longer Period environmental influences is exposed.
Dass durch das zuvor beschriebene Verfahren hergestellte Kontaktelement eignet sich in besonders guter Weise für die Kontaktierung mit einem Aluminiumflachbandleiter. Daher wird vorgeschlagen, dass die aus Aluminium gebildete Seite des Kontaktelements stoffschlüssig mit einem Flachbandleiter verbunden wird. Möglich ist beispielsweise die Kontaktierung entlang der schmalen Seite der Anschlussfahne aus Aluminium. So ist es beispielsweise möglich, dass das Kontaktelement mit einer gleichen Stärke hergestellt wird, wie der Flachbandleiter. Dann kann in besonders einfacher Weise eine Kontaktierung zwischen Kontaktelement und Flachbandleiter erfolgen. Es ist jedoch auch möglich, dass das Kontaktelement mit der breiten Seite der Aluminium-Anschlussfahne mit dem Flachbandleiter stoffschlüssig verbunden wird.That Contact element produced by the method described above is particularly suitable for contacting with a Aluminum ribbon cables. Therefore it is suggested that the Aluminum formed side of the contact element cohesively with a ribbon cable is connected. Possible, for example, the Contacting along the narrow side of the connection lug Aluminum. For example, it is possible that the contact element with an equal strength is made, such as the ribbon conductor. Then in particular easy way a contact between contact element and ribbon conductor respectively. However, it is also possible that the contact element with the wide side of the aluminum terminal lug is materially connected to the ribbon conductor.
Gemäß eines vorteilhaften Ausführungsbeispiels ist es jedoch auch möglich, die Aluminium-Anschlussfahne des Kontaktelementes mit einem Aluminium-Rundleiter stoffschlüssig zu verbinden. Beispielsweise bei der Verwendung von Aluminium-Rundleitern kann somit eine einfache und kostengünstige Verbindungstechnik für die Verbindung eines Aluminiumleiters mit einem Kupferleiter zur Verfügung gestellt werden. Die Verbindung zwischen Aluminium-Anschlussfahne und Aluminiumleitung wird bevorzugt mittels eines Schrumpfschlauches vor Umwelteinflüssen geschützt. Da die Aluminium-Aluminium-Verbindung nur wenig vor Korrosion geschützt werden muss, reicht ein Schrumpfschlauch und eine Umspitzung ist nicht notwendig.According to one advantageous embodiment but it is also possible the aluminum terminal lug of the contact element with an aluminum round conductor cohesively connect to. For example, when using aluminum round conductors Thus, a simple and inexpensive connection technology for the connection of a Aluminum conductor can be provided with a copper conductor. The connection between aluminum terminal lug and aluminum line is preferred Protected against environmental influences by means of a heat-shrinkable tube. Because the aluminum-aluminum compound is little protected against corrosion must be a shrink tube and a Umspitzen is enough unnecessary.
Ein weiterer Gegenstand ist ein elektrisches Kontaktelement mit einer aus einem Aluminium-Flachteil gebildeten ersten Anschlussfahne und einer aus einem aus Übergangsmetall gebildeten Flachteil gebildeten zweiten Anschlussfahne, wobei die Anschlussfahnen stoffschlüssig miteinander verbunden sind, und wobei eine Nahtstelle zwischen der ersten Anschlussfahne und der zweiten Anschlussfahne isoliert ist. Dieses Kontaktelement hat den Vorteil, dass es eine einfache Kontaktierung zwischen Aluminium und Übergangsmetallen ermöglicht, in dem es zwischen einem Aluminiumleiter und einem Leiter, beispielsweise aus Kupfer, angeordnet wird. Durch die Isolation an der Nahtstelle zwischen der ersten Anschlussfahne und der zweiten Anschlussfahne ist die Verbindung zwischen Aluminium und Übergangsmetall gut vor Korrosionen geschützt. Das Kontaktelement lässt sich besonders einfach herstellen und ermöglicht eine kostengünstige, einfach handhabbare Kontaktierung.One Another object is an electrical contact element with a from a flat aluminum part formed first terminal lug and a from one of transition metal formed flat part formed second terminal lug, wherein the Connection lugs cohesive connected to each other, and wherein an interface between the first Terminal lug and the second terminal lug is isolated. This Contact element has the advantage that it is a simple contact between aluminum and transition metals allows in which it is between an aluminum conductor and a conductor, for example made of copper, is arranged. Due to the insulation at the interface between the first terminal lug and the second terminal lug The connection between aluminum and transition metal is good against corrosion protected. The contact element leaves easy to manufacture and enables cost-effective, easy to handle contacting.

Diese Lösung ist ebenfalls bereits eigenständig erfinderisch.Also possible is a production of a contact element, in which the flat parts not from ribbons be shaved off, but from bulk material of flat copper parts and aluminum, which were produced in a pre-process. The flat parts will be then preferably welded together by means of a welding process. This For example, by means of multi-orbital welding in a pallet production respectively. This solution is also already independent inventive.
