Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren und eine Verbindung zur Kontaktierung eines isolierten Kabels, das aus Einzelleitern aus Aluminium oder einer Aluminiumlegierung besteht, mit einer metallischen, an den Innenseiten verzinnten Kontaktklemme, vorzugsweise aus Kupfer oder einer Kupferlegierung.The The invention relates to a method and a connection to Contacting an insulated cable made of single conductors Aluminum or an aluminum alloy, with a metallic, on the inner sides tinned contact terminal, preferably made of copper or a copper alloy.
Auf dem Gebiet des Automobilbaus und auch des Flugzeugbaus gewinnt die Frage der Gewichtseinsparung und der damit verbundenen, erwünschten Senkung des Kraftstoffverbrauchs durch den Ersatz der schweren Kupferkabel durch Aluminiumkabel zunehmende Bedeutung. Aluminium kann jedoch für eine dauerhafte und gute Kontaktierung nicht ohne besondere vorbereitende Maßnahmen verwendet werden. Nachdem Aluminium und auch die Einzelleiter eines Aluminiumkabels stets von einer Aluminiumoxidschicht umschlossen sind, die eine erhebliche Erhöhung des Übergangswiderstandes bewirkt, muß die Wirkung der Oxidschicht ausgeschaltet oder zumindest reduziert werden. Bei den Einzelleitern von Aluminiumkabeln tritt natürlich das Problem der isolierenden Oxidschichten zwischen den Einzelleitern gegenüber einem Vollkabel noch mehr in den Vordergrund, sodaß hier die Übergangswiderstände wegen der Erwärmung des Kabels bei Stromfluß nicht tolerierbar sind.On In the field of automobile construction and also the aircraft industry wins the Question of weight saving and the associated, desirable Reduce fuel consumption by replacing heavy copper cables due to aluminum cable increasing importance. Aluminum, however, can for one permanent and good contact not without special preparatory Measures used become. After aluminum and also the single conductors of an aluminum cable are always enclosed by an aluminum oxide layer, the one significant increase the contact resistance causes, must Effect of the oxide layer turned off or at least reduced. Of course, the problem is with the single conductors of aluminum cables the insulating oxide layers between the individual conductors compared to a Full cable even more in the foreground, so here the contact resistance because the warming of the cable when current is not flowing are tolerable.
Der Anschluß von Aluminiumkabeln an das Bordnetz von Fahrzeugen erfolgt über Kontaktklemmen aus Kupfer, die über die Aluminiumkabel geschoben werden. Um einen guten Kontakt zwischen der Kupferkontaktklemme und dem Aluminiumkabel zu gewährleisten, sind zwei Probleme zu lösen. Das übliche Verpressen der Kontaktklemme auf dem Kabel ist bei Aluminiumkabeln deswegen nur bedingt geeignet, da sich Aluminium bei einem auf ihn ausgeübten Druck in seinem Gefüge „setzt", wodurch die inneren Spannungen im Aluminium mit der Zeit abgebaut werden. Aufgrund dieses „setzens" wird jedoch die Klemmverbindung mit der Zeit locker, was zum einen den Übergangswiderstand erhöht und zum andern die Aufnahmefähigkeit für die auf die Verbindung ausgeübten Zugkräfte reduziert. Das zweite, und noch größere Problem stellt die Kontaktkorrosion zwischen Aluminium und Kupfer dar. Eine solche galvanische Korrosion tritt immer dann auf, wenn Metalle mit stark unterschiedlichem Normalpotential in direktem Kontakt miteinander stehen. Kupfer ist ein „edles" Metall mit einem positiven Normalpotential, wohingegen das „unedle" Aluminium ein stark negatives Normalpotential besitzt. An der Berührungsfläche von Aluminium und Kupfer kommt es infolge der großen Potentialdifferenz zu einem Potentialausgleich, was zur Folge hat, daß das unedlere Metall, also Aluminium, zerstört wird. Zur Vermeidung der Kontaktkorrosion muß daher bei dem Aluminium zunächst das Aluminiumoxid entfernt und dann das Aluminium verzinnt werden, sodaß kein Aluminium mit der Außenluft oder mit der Kupferkontaktklemme in Kontakt kommen kann. Um eine bessere Kontaktverbindung zu erhalten, werden die Kupferkontaktklemmen an ihrer Innenseite ebenfalls verzinnt.Of the Connection of Aluminum cables to the on-board network of vehicles via contact terminals made of copper, over the aluminum cables are pushed. To get a good contact between the To ensure copper contact terminal and the aluminum cable, There are two problems to solve. The usual Pressing the contact terminal on the cable is on aluminum cables therefore only conditionally suitable, since aluminum at one on him exerted Pressure in its structure "sets", causing the inner Tensions in the aluminum are degraded over time. Due to this "setting", however, the Clamp connection with time loose, which on the one hand the contact resistance elevated and on the other hand the receptivity for the exercised on the connection tensile forces reduced. The second, and even greater problem is the contact corrosion between Aluminum and copper. Such galvanic corrosion occurs always on, when metals with strongly different normal potential in direct contact with each other. Copper is a "noble" metal with one positive normal potential, whereas the "base" aluminum has a strong negative normal potential has. At the contact surface of Aluminum and copper are due to the large potential difference to one Equipotential bonding, which has the consequence that the less noble metal, ie Aluminum, destroyed becomes. To avoid the contact corrosion must therefore at first the aluminum Remove alumina and then tin the aluminum so that no aluminum with the outside air or can come into contact with the copper contact terminal. To one To get better contact connection, the copper contact terminals also tinned on its inside.

In der älteren Anmeldung DE 103 46 160.4.-34 ist eine Lösung beschrieben, welche ohne Hülse und ohne eine Verpressung auskommt. Die dort dargestellten fakultativen Lösungen mit Hülse und Verpressung sind Sonderfälle, bei denen es um die Erfüllung besonderer Bedingungen geht. Bei dieser Ausführung gemäß der älteren Patentanmeldung wird eine oben offene Kontaktklemme über die abisolierten Einzelleiter des Alu miniumkabels geschoben und durch die vom Kabelende abgewandte Bohrungsöffnung vermittels einer Sonotrode ultraschallverzinnt. Die Befestigung der Kontaktklemme auf dem Kabelende erfolgt durch Widerstands- oder induktive Erwärmung.In the older one Application DE 103 46 160.4.-34 describes a solution which without sleeve and works without a compression. The facultative presented there solutions with sleeve and Compression are special cases, when it comes to fulfillment special conditions. In this embodiment according to the earlier patent application is an open top contact terminal over pushed the stripped individual conductors of the aluminum cable and through the hole opening facing away from the cable end by means of a sonotrode ultraschallverzinnt. The attachment of the contact terminal on the cable end done by resistance or inductive heating.
Die im Zusammenhang mit der Erfindung bestehende Problematik bei den Gegenständen gemäß den beiden vorbeschriebenen Patentanmeldungen besteht in dem Außendurchmesser über der Kontaktklemme. Bei der Lösung gemäß der erstgenannten Patentanmeldung sind Kontaktklemmen aus Kupfer verwendet, welche keine durchgehende Bohrung sondern eine Sacklochbohrung aufweisen. In diesen Fällen muß über das abisolierte Ende des Aluminiumkabels eine Hülse geschoben sein, mittels der später eine Verbindung mit der Kontaktklemme erfolgt. Letztere hat somit einen Außendurchmesser, der in etwa 4mm, nämlich 2mal die Wandstärke der Kontaktklemme größer ist als der Durchmesser der Hülse und des Kabels.The in connection with the invention existing problems in the objects according to the two above-described patent applications consists in the outer diameter above the Contact terminal. At the solution according to the first-mentioned patent application are contact terminals made of copper, which are not continuous Bore but have a blind hole. In these cases must over the stripped end of the aluminum cable to be pushed a sleeve by means of the later a connection with the contact terminal takes place. The latter has thus an outer diameter, the in about 4mm, namely 2 times the wall thickness the contact terminal is larger as the diameter of the sleeve and the cable.
Bei der zweitgenannten Patentanmeldung, bei der die Hülse entfallen kann, weil die Kontaktklemme eine durchgehende Bohrung besitzt und die Verzinnung durch die Öffnung der Bohrung erfolgen kann, ist eine Hülse nicht erforderlich. Infolgedessen kann der Durchmesser der Kontaktklemme kleiner sein als in dem vorbeschriebenen Fall. Oftmals spiet der Außendurchmesser der Kontaktklemme eine wichtige Rolle, wenn es nämlich um die Anpassung an bereits vorhandene Systeme geht. Wenn das vorhandene System jedoch nur Kontaktklemmen mit einer Sacklochbohrung anbietet, jedoch ein kleiner Durchmesser gewünscht ist, sind die beiden vorbeschriebenen Lösungen nicht verwendbar.at the second-mentioned patent application, in which the sleeve omitted can because the contact terminal has a through hole and the tinning through the opening the bore can be done, a sleeve is not required. As a result, can the diameter of the contact terminal be smaller than in the above Case. Often the outside diameter spits the contact clamp an important role, when it comes to adapting to already existing systems goes. However, if the existing system only contact terminals offers a blind hole, but a small diameter required is, the two solutions described above are not usable.
Aufgabe der Erfindung ist es nun, ein Verfahren und eine Verbindung zur Kontaktierung eines Aluminiumkabels vorzuschlagen, bei der Kontaktklemmen zum Einsatz kommen, die keine durchgehende Bohrung sondern eine Sacklochbohrung aufweisen und bei denen das Vorhandensein einer Hülse nicht Voraussetzung ist, sondern darauf verzichtet werden kann.task The invention is now a method and a compound for Contacting an aluminum cable to suggest, at the contact terminals are used, the no through hole but a Have blind hole and where the presence of a Sleeve not required is, but it can be waived.
Zur Lösung dieser Aufgabe schlägt die Erfindung zwei alternative Verfahren vor, die in den Ansprüchen 1 und 2 gekennzeichnet sind.to solution this task strikes the invention provides two alternative methods, which in the claims 1 and 2 are marked.
Wesentlich in beiden Fällen ist eine allseitige Ultraschallverzinnung des abisolierten und aus Einzelleitern bestehenden Ende eines Aluminiumkabels, wobei „allseitig" eine Verzinnung an der Stirn- und den Wandseiten des Kabels bedeutet. In beiden Fällen wird in die Sacklochbohrung der Kontaktklemme Lötpaste eingefüllt und anschließend die Kontaktklemme über die verzinnten Einzelleiter geschoben und dort soweit erwärmt, daß das auf den Einzelleitern abgeschiedene Zinn bzw. die Lötpaste flüssig werden und bei ihrem Erkalten eine sehr gute und feste Verbindung von Kontaktklemme und Kabelende erzeugen.Essential in both cases is an all-round ultrasonic tinning of the stripped and off Single conductors existing end of an aluminum cable, with "all sides" a tinning on the front and the wall sides of the cable means. In both make is filled in the blind hole of the contact terminal solder paste and subsequently the contact terminal over pushed the tinned individual conductors and there so far heated that on the individual conductors separated tin or solder paste are liquid and when they cool create a very good and firm connection of contact terminal and cable end.
Die Zinndicke auf dem Kabelende hängt von der Einwirkungszeit der Sonotroden ab. Wenn eine ausreichende Zinndicke auf das Kabelende aufgebracht werden kann und die Anforderungen an die Zugfestigkeit der Kontaktverbindung nicht zu hoch sind, kann das Einbringen der Lötpaste in die Sacklochbohrung bei den beiden vorbeschriebenen alternativen Lösungen entfallen. Durch die Erwärmung der aufgeschobenen Kontaktklemme wird eine ausreichend feste Zinnverbindung in einem solchen Fall erzeugt. Dieser Sonderfall des Entfalls der Lötpaste ist eine weitere Ausbildung der Erfindung und insoweit auch ausdrücklich erfindungswesentlich.The Tin thickness hangs on the cable end from the exposure time of the sonotrodes. If sufficient Tin thickness can be applied to the cable end and the requirements to the tensile strength of the contact connection are not too high, can the introduction of the solder paste in the blind hole in the two above-alternative solutions omitted. By warming the deferred contact terminal is a sufficiently strong tin compound generated in such a case. This special case of the cancellation of the Solder paste is a further embodiment of the invention and to that extent also expressly essential to the invention.
In einer Weiterbildung der Erfindung ist vorgesehen, daß anstelle der Lötpaste Zinn oder eine Zinnlegierung in fester Form in die Sacklochbohrung der Kontaktklemme eingebracht und dort kurzzeitig erwärmt wird, ehe die Kontaktklemme dann über das verzinnte Kabelende geschoben wird. Für den Entfall von Zinn oder Zinnlegierung in der Sacklochbohrung gilt natürlich das Gleiche wie für den Entfall der Lötpaste.In a development of the invention is provided that instead the solder paste Tin or a tin alloy in solid form in the blind hole of the Contact terminal is introduced and heated there for a short time, before the contact terminal over the tinned cable end is pushed. For the removal of tin or Tin alloy in the blind hole, of course, the same applies as for the elimination the solder paste.
Gemäß einer Weiterbildung der Erfindung ist vorgesehen, daß die Ultraschallverzinnung durch eine stirnseitig zum Kabelende und mehrere, vorzugsweise 3, in gleichmäßigen Abständen um den Umfang des Kabelendes angeordnete Sonotroden erfolgt.According to one Further development of the invention is provided that the ultrasonic tinning through a front end to the cable end and a plurality, preferably 3, evenly spaced around The circumference of the cable end arranged sonotrodes takes place.
Weitere Ausbildungen des erfindungsgemäßen Verfahrens sind in den weiteren Unteransprüchen gekennzeichnet.Further Embodiments of the method according to the invention are in the further subclaims characterized.
Eine Verbindung, die nach einem der beiden alternativen Verfahren hergestellt ist, ist in den Ansprüchen 8 und 9 gekennzeichnet.A Compound prepared by one of the two alternative methods is in the claims 8 and 9 marked.
