Description
Die Erfindung betrifft Verfahren und eine Verbindung zur Kontaktierung eines isolierten Kabels, das aus Einzelleiten aus Aluminium oder Aluminiumlegierung besteht, mit einer metallischen, verzinnten Kontaltklemme.The invention relates to methods and a connection for contacting an insulated cable, the consists of individual conductors made of aluminum or aluminum alloy, with a metallic, tin-plated clamp.
Auf den Gebieten des Flugzeugbaus und der Fahrzeugtechnik gewinnen im Zuge von Gewichtseinsparungen und damit einhergehend der Senkung des Kraftstoffverbrauchs elektrische Aluminiumleitungen eine größere Bedeutung und ersetzen zunehmend die relativ schweren Kabel aus Kupfer. Die intrinsischen Eigenschaften des Aluminiums erfordern jedoch, daß, um eine dauerhafte, leistungsstarke Kontaktierung der Aluminiumdrähte zu gewährleisten, bestimmten Vorkehrungen getroffen werden müssen. So wird Aluminium stets von einer isolierenden Aluminiumoxid-Schicht (Al2O3) umschlossen, die eine erhebliche Erhöhung des elektrischen Übergangswiderstandes bewirkt. Um Leitungsverluste und um die damit einhergehende unzulässige Erwärmung eines Aluminiumkabels aufgrund des Übergangswiderstandes der Oxidschicht zu reduzieren, müssen besondere Maßnahmen ergriffen werden, die eine Kontaktierung des „reinen" Aluminiums ermöglichen und die isolierende Wirkung der Oxidschicht weitestgehend ausschließen. Dies insbesondere auch deshalb, weil zur Erzielung einer höheren Flexibilität solche Kabel verwendet werden, die aus mehreren Einzelleitern wie Litzen aufgebaut sind und ein jeder Einzelleiter von einer Oxidschicht umschlossen wird und dadurch der Übergangswiderstand weiter erhöht wird.In the fields of aircraft construction and vehicle technology, in the course of weight savings and the associated reduction in fuel consumption, electrical aluminum lines are becoming increasingly important and are increasingly replacing the relatively heavy copper cables. However, the intrinsic properties of aluminum require that certain precautions be taken to ensure permanent, high-performance contacting of the aluminum wires. For example, aluminum is always enclosed in an insulating aluminum oxide layer (Al 2 O 3 ), which causes a considerable increase in the electrical contact resistance. In order to reduce line losses and the associated inadmissible heating of an aluminum cable due to the contact resistance of the oxide layer, special measures must be taken that allow contacting the "pure" aluminum and largely exclude the insulating effect of the oxide layer In order to achieve greater flexibility, cables can be used that are made up of several individual conductors such as strands and each individual conductor is surrounded by an oxide layer, thereby further increasing the contact resistance.
Unter Verwendung von Kupfertechnik werden Kontaktklemmen an Kabeln üblicherweise durch Verpressen befestigt: Dies ist im Zusammenhang mit Aluminiumkabeln nur bedingt geeignet, da ein auf Aluminium ausgeübter Druck mit der Zeit durch sog. „Setzen", also einem langsamen Abbau der Druckspannungen im Aluminium abgebaut wird. Dies führt dazu, daß eine Klemmverbindung locker wird und auf diese Weise der Übergangswiderstand an der Kontaktstelle ebenfalls steigt.Using copper technology are usually contact terminals on cables attached by crimping: this is related to aluminum cables only suitable to a limited extent, as a pressure exerted on aluminum over time so-called "setting", ie a slow one Reduction of the compressive stresses in the aluminum is reduced. This leads to, that a Clamp connection becomes loose and in this way the contact resistance also rises at the contact point.
Ein weiteres Problem bei der Nutzung von Aluminium bei elektrisch leitenden Verbindungen stellt die Kontaktkorrosion dar. Eine solche galvanische Korrosion tritt immer dann auf, wenn Metalle mit stark unterschiedlichem Normalpotential in direktem Kontakt miteinander stehen. Kupfer, aus dem üblicherweise Kontaktklemmen gefertigt sind, ist ein „edles" Metall mit einem positiven Normalpotential, wogegen 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.Another problem with usage of aluminum in electrically conductive connections is contact corrosion Such galvanic corrosion always occurs when Metals with very different normal potential in direct contact stand together. Copper, from which usually contact terminals are made is a "noble" metal with a positive normal potential, whereas the "base" aluminum has a strongly negative normal potential has. At the interface of Aluminum and copper occur due to the large potential difference Equipotential bonding, which means that the less noble metal, that is Aluminum, destroyed becomes.
In der
Trotzdem ist dieses Verfahren zur Kontaktierung eines Aluminiumkabels nur bedingt geeignet. Um den elektrischen Übergangswiderstand zwischen den einzelnen Litzen des Kabels zu verringern, wird der Kontakt zwischen benachbarten Litzen dadurch verbessert, daß diese aneinandergepreßt und in dieser Position dauerhaft fixiert werden. Abhilfe gegen die isolierende Wirkung der Aluminiumoxid-Schicht und den hohen Übergangswiderstand wird hierdurch jedoch nicht geschaffen. Weiterhin trägt das offenbarte Verfahren dem elektrochemischen Verhalten zwischen den unterschiedlichen Materialien keine Rechnung und ermöglicht somit Kontaktkorrosion an Grenzflächen zwischen unterschiedlichen Metallen, also beispielsweise am Übergang Kabel-Kabelschuh oder Kabelschuh-Anschlußstelle, sofern keine absolut luftdichte Abdichtung besteht, was in der Praxis nie gegeben ist. Weiterhin können keine verläßlichen Angaben über die Dauerhaftigkeit einer solchen Klebverbindung gemacht werden. Da handelsübliche Kleber altern, ist davon auszugehen, daß die auf den Kleber einwirkenden extremen Bedingungen bei der Nutzung eines Fahrzeuges, wie z.B. starke Temperaturschwankungen und hohe mechanische Beanspruchung durch Vibrationen, während der langen Lebensdauer eines Fahrzeugs nachteilig auf die Verbindung Einfluß nehmen.Even so, this procedure is Contacting an aluminum cable is only suitable to a limited extent. To the electrical contact resistance between the individual strands of the cable, the Contact between neighboring strands is improved by the fact that these against one another and be permanently fixed in this position. Remedy against the insulating effect of the aluminum oxide layer and the high contact resistance is not created by this. Furthermore, the disclosed carries Process the electrochemical behavior between the different Materials do not charge and therefore allow contact corrosion at interfaces between different metals, for example at the transition Cable lug or cable lug connection point, unless there is an absolutely airtight seal, which never happens in practice given is. Can continue no reliable information about durability be made of such an adhesive connection. Because commercial glue aging, it can be assumed that those acting on the adhesive extreme conditions when using a vehicle, such as strong temperature fluctuations and high mechanical stress through vibrations while the long life of a vehicle detrimental to the connection To influence.

Obwohl der Stromtransport direkt von der Stirnseite des Kabels in das Anschlußteil erfolgt, stellt die offenbarte Verbindung keine befriedigende Lösung für das Verbinden von Aluminiumkabel mit Kupferanschlußteil dar. Denn ebenso wie der Stromtransport direkt über die Stirnseite des Kabels verläuft, wirken mechanische Belastungen beispielsweise durch Zug am Kabel, da keine Zugentlastung vorgesehen ist, auf die Verbindung an der Stirnseite des Kabels ein. Aus mechanischen Zusammenhängen ergibt sich, daß hier Zugkräfte direkt in Zugrichtung auftreten und nicht quer zur Zugrichtung verteilt und somit abgeschwächt werden. Infolgedessen hat die vorgeschlagene Verbindung nur eine unzureichende mechanische Festigkeit.Although the electricity transport directly done from the front of the cable into the connector, provides the disclosed Connection not a satisfactory solution for the Connecting aluminum cable with copper connector part. Because just like the electricity transport directly over the end of the cable runs act mechanical loads, for example by pulling the cable, since no strain relief is provided, on the connection at the Face of the cable. From mechanical relationships yourself that here tensile forces occur directly in the direction of pull and not distributed across the direction of pull and thus weakened become. As a result, the proposed connection has only one insufficient mechanical strength.

In Erkenntnis der Unzulänglichkeiten des Standes der Technik ist es Aufgabe der Erfindung, ein Verfahren und eine Verbindung zur Kontaktierung und Befestigung eines Aluminiumkabels anzugeben, bei dem der Übergangswiderstand zwischen den Litzen und zwischen Hülse und Kontaktklemme weiter reduziert wird und Kontaktkorrosion zwischen den Einzelleitern untereinander und mit der Hülse vermieden wird.Realizing the shortcomings In the prior art, the object of the invention is a method and a connection for contacting and fastening an aluminum cable specify at which the contact resistance between the strands and between the sleeve and contact terminal further reduced contact corrosion between the individual conductors and with the sleeve is avoided.
Diese Aufgabe wird erfindungsgemäß durch die in den Ansprüchen 1, 3 und 5 angegebenen Merkmale gelöst. Danach wird ein Aluminiumkabel, das aus Einzelleitern wie Drähten oder Litzen aufgebaut ist, in der Weise kontaktiert, daß ein Ende des Kabels abisoliert wird und über dieses Ende eine metallische, vorzugsweise kupferne und zumindest an seiner Innenseite verzinnte Hülse geschoben wird, und zwar soweit, daß ein Ende der Hülse bündig mit der Stirnseite des Kabels abschließt oder daß das Ende der Hülse über die Stirnseite des Kabels hinaussteht. Mittels Ultraschall-Verzinnung wird die Hülse mit den Einzelleitern am Ende des Kabels dauerhaft metallisch verbunden. Schließlich wird eine Kontaktklemme aus Kupfer, die vorzugsweise ebenfalls verzinnt ist, über das verzinnte Ende des Kabels geschoben und mit dem Kabel verpreßt.This object is achieved by the in the claims 1, 3 and 5 specified features solved. After that, an aluminum cable that from individual conductors such as wires or strands is constructed in such a way that one end contacts the cable is stripped and over this end a metallic, preferably copper and at least tinned sleeve on the inside is pushed so far that one end of the sleeve is flush with the Completes the end of the cable or that the end the sleeve over the End of the cable protrudes. Using ultrasonic tinning becomes the sleeve permanently connected to the individual conductors at the end of the cable. Finally is a contact terminal made of copper, which is also preferably tinned is about pushed the tinned end of the cable and pressed it with the cable.
Die Ultraschall-Verzinnung der einzelnen Al-Leiter wird in einem flüssigen Zinnbad durchgeführt, und zwei so, daß das zu verzinnende Ende des Kabels stirnseitig frontal gegenüber einer Ultraschall erzeugenden Sonotrode positioniert wird. Durch den erzeugken Schalldruck wird die Flüssigkeit des Zinnbades auf die Stirnseite des Kabels zubeschleunigt und bewirkt, daß die Aluminiumoxid-Schicht aufgebrochen wird. Das geschieht sowohl stirnseitig als auch im Innenbereich des Kabels zwischen den Einzelleitern. An den Stellen, wo die Oxidschicht aufgerissen wurde, lagert sich an freiliegendem, „reinem" Aluminium Material des Zinnbades an und baut so leitende Zinnverbindungen zwischen den Einzelleitern bzw. zwischen diesen und der Hülse auf. Die auf diese Weise aufgebauten leitenden Zinnverbindungen werden durch eine mögliche Oxidation des Aluminiums nicht beeinträchtigt.Ultrasonic tinning of the individual Al conductors is in a liquid Tin bath performed, and two so that the The end of the cable to be tinned frontally opposite one Ultrasound generating sonotrode is positioned. By generating Sound pressure becomes the liquid accelerates the tin bath towards the front of the cable and causes that the Alumina layer is broken up. This happens both on the front and in the Inner area of the cable between the individual conductors. In the places where the oxide layer was torn open, exposed, "pure" aluminum material of the tin bath and builds conductive tin connections between the individual conductors or between them and the sleeve. That way built up conductive tin compounds are caused by a possible oxidation of the aluminum is not affected.
Die Ultraschall-Verzinnung bewirkt, daß sich stirnseitig am Ende des Kabels eine deckelartige, dauerhafte Zinnverbindung bildet, welche die Einzelleiter untereinander bzw. mit der Hülse leitend verbindet. Eine solche elektrisch leitende Zinn verbindung kann sich auch teilweise in die Tiefe des abisolierten Endes des Kabels erstrecken und dort die Einzelleiter mit der Hülse verbinden.Ultrasonic tinning causes that face up at the end of the cable a lid-like, permanent tin connection forms which the individual conductors with each other or with the sleeve conductive combines. Such an electrically conductive tin compound can also extend partially into the depth of the stripped end of the cable and connect the individual conductors to the sleeve there.
Als letzter Verfahrensschritt wird schließlich eine Kontaktklemme, die sich in ihrer Endposition über die Hülse hinweg auf den anschließenden isolierten Teil des Kabels erstreckt, mit der Hülse und der anschließenden Isolierung formschlüssig verpreßt. Dabei werden Kontaktklemme und Hülse so miteinander verpreßt, daß der Bereich, über den sich die Zinnverbindung in der Hülse erstreckt, von der Verpressung ausgenommen wird.The last step is finally one Contact terminal, which in its end position isolated over the sleeve on the subsequent one Part of the cable extends, with the sleeve and the subsequent insulation form-fitting pressed. The contact clamp and sleeve so pressed together that the Area, about which the tin connection extends in the sleeve, from the pressing is excluded.
In einem alternativen Verfahren zur Kontaktierung eines aus Einzelleitern wie Drähten oder Litzen aufgebauten Aluminiumkabels wird eine gegenüber Kupfer bevorzugte Hülse aus Aluminium über das abisolierte Ende des Kabels geschoben und mit den Einzelleitern am Ende des Kabels stirnseitig mittels Wolfram-Inertgasschweißen oder Metall-Inertgasschweißen dauerhaft verschweißt. Schließlich wird eine verzinnte Kontaktklemme über das verschweißte Ende des Kabels geschoben und mit diesem verpreßt. Die weiteren Verfahrensschritte entsprechen den Schritten, wie sie bereits im vorher beschriebenen Verfahren angegeben wurden.In an alternative method for contacting an aluminum cable made up of individual conductors such as wires or strands, an aluminum sleeve, which is preferred over copper, is pushed over the stripped end of the cable and permanently welded to the individual conductors at the end of the cable by means of tungsten inert gas welding or metal inert gas welding. Finally, a tinned contact clamp is pushed over the welded end of the cable and pressed with it. The further process steps correspond to the steps as described above NEN procedures were specified.
Eine erfindungsgemäße Verbindung zur Kontaktierung und Befestigung eines aus Einzelleitern wie Drähten oder Litzen aufgebauten Aluminiumkabels weist eine zumindest an der Innenseite verzinnte Hülse auf, die über ein abisoliertes Kabelende geschoben ist und mit den Einzelleitern dauerhaft durch eine stirnseitige, deckelartige Zinn- oder Schweißverbindung verbunden ist, wobei sich die Zinn- oder Schweißverbindung zusätzlich oder ausschließlich teilweise in das Innere des Kabelendes erstrecken kann. Weiterhin weist die Verbindung eine vorzugsweise verzinnte Kontaktklemme aus Kupfer bzw. aus Kupferlegierung aus, die das Kabelende mit der Hülse und einen Teil der an die Hülse angrenzenden Isolation umschließt und formschlüssig mit Hülse und Isolation verpreßt ist. Dabei ist der Teil der Hülse, in dem die Zinn- bzw. Schweißverbindung ausgebildet ist, von der Verpressung ausgenommen.A compound according to the invention for contacting and fastening one made of individual conductors such as wires or Stranded aluminum cable has a tin-plated at least on the inside Sleeve on, the above a stripped cable end is pushed and with the individual conductors permanent thanks to a cover-like tin or weld connection on the front is connected, the tin or welded joint being additionally or exclusively can extend partially into the interior of the cable end. Farther the connection has a preferably tinned contact terminal Copper or copper alloy made of the cable end with the sleeve and part of the to the sleeve encloses adjacent insulation and form-fitting with sleeve and Insulation pressed is. The part of the sleeve in the tin or welded joint is trained, excluded from the pressing.
