Description

Die Erfindung bezieht sich auf ein Verfahren zum Befestigen eines Kontaktelements am Ende eines elektrischen Leiters, der aus einer Vielzahl von miteinander verseilten Einzeldrähten aus einem Aluminium enthaltenden Material besteht, mit welchem um das Ende des Leiters eine rohrförmige, als Kontaktelement dienende und aus einem Metall bestehende Hülse herumgelegt und mit dem Leiter verpreßt wird ( DE 199 08 031 B4 ).The invention relates to a method for attaching a contact element at the end of an electrical conductor, which consists of a plurality of stranded individual wires made of an aluminum-containing material with which around the end of the conductor a tubular, serving as a contact element and made of a metal Wrapped around the sleeve and pressed with the conductor ( DE 199 08 031 B4 ).

Die Hülse kann aus einem Metall auf Aluminiumbasis bestehen, und zwar entweder aus Aluminium oder aus einer Aluminiumlegierung. Das gilt auch für die Einzeldrähte des Leiters. Im Folgenden wird nur das Material "Aluminium" berücksichtigt.The sleeve may be made of aluminum-based metal, either aluminum or an aluminum alloy. This also applies to the individual wires of the conductor. In the following, only the material "aluminum" is considered.

Leiter aus Aluminium werden insbesondere aus Gewichts- und Kostengründen vermehrt als Ersatz für Kupferleiter verwendet. Haupteinsatzgebiete derartiger Leiter sind beispielsweise die Automobil- und die Flugzeugtechnik. Die geringere elektrische Leitfähigkeit des Aluminiums gegenüber Kupfer spielt für die meisten Anwendungen keine Rolle, da sie gegebenenfalls durch eine Querschnittsanpassung kompensiert werden kann. Probleme ergeben sich aber beim Anbringen von Kontaktteilen an den Leitern, da Aluminiumleiter von einer elektrisch sehr schlecht leitenden Oxidschicht umgeben sind. Dieser Mangel macht sich besonders bei aus einer Vielzahl von Einzeldrähten bestehenden, auch als Litzenleiter bezeichneten Leitern bemerkbar, von denen jeder von einer ohne Sonderbehandlung nicht zu vermeidenden Oxidschicht umgeben ist. Diese Problematik ist seit langem bekannt und in zahlreichen Druckschriften beschrieben, von denen im Folgenden drei Schriften erwähnt sind.Ladders made of aluminum are increasingly being used, in particular for reasons of weight and cost, as a replacement for copper conductors. Main applications of such conductors are, for example, the automotive and aircraft technology. The lower electrical conductivity of the aluminum over copper is irrelevant for most applications, as it may be compensated for by cross-sectional matching. However, problems arise when attaching contact parts to the conductors, since aluminum conductors are surrounded by an electrically very poorly conductive oxide layer. This deficiency is particularly noticeable in existing from a variety of individual wires, also referred to as stranded conductors conductors, each of which is surrounded by an unavoidable without special treatment oxide layer. This problem has long been known and described in numerous publications, of which three documents are mentioned below.

Aus der DE 102 23 397 B4 geht ein Verfahren hervor, mit dem ein Kontaktelement elektrisch gut leitend an einem Litzenleiter aus Aluminiumdrähten angebracht werden soll. Dazu wird auf das Ende des Litzenleiters zunächst eine an der Innenseite verzinnte metallische Hülse aufgeschoben. Die Einzeldrähte werden dann an ihren Stirnseiten untereinander und mit der Hülse mittels Ultraschalls oder Schutzgasschweißens verzinnt oder verschweißt. Die die Einzelleiter umgebenden Oxidschichten sollen dabei aufgebrochen werden. Es ergibt sich eine deckelartige Verzinnung bzw. Verschweißung am Ende des Litzenleiters. Abschließend wird das Kontaktelement aufgeschoben und mit dem Ende des Litzenleiters verpreßt. Die deckelartige Verzinnung bzw. Verschweißung wird vom Verpressen ausgenommen.From the DE 102 23 397 B4 goes out a method by which a contact element is to be mounted electrically good conduction on a stranded wire of aluminum wires. For this purpose, a tin-plated on the inside of metallic sleeve is first pushed onto the end of the stranded conductor. The individual wires are then tinned or welded at their ends with each other and with the sleeve by means of ultrasound or inert gas welding. The oxide layers surrounding the individual conductors should thereby be broken up. This results in a cover-like tinning or welding at the end of the stranded conductor. Finally, the contact element is pushed and pressed with the end of the stranded conductor. The lid-like tinning or welding is excluded from the pressing.

Die DE 103 46 160 B3 beschreibt ein Verfahren zur Kontaktierung eines als Litzenleiter ausgeführten Aluminiumleiters, bei welchem auf das Ende des Aluminiumleiters eine an der Innenseite verzinnte, beispielsweise aus Kupfer bestehende Kontaktklemme aufgeschoben wird. Die rohrförmig ausgeführte Kontaktklemme wird an der Stirnseite des Aluminiumleiters mittels Ultraschall-Verzinnung gemeinsam mit demselben verzinnt oder mittels eines bekannten Schweißverfahrens metallisch mit demselben verschweißt.The DE 103 46 160 B3 describes a method for contacting an aluminum conductor designed as a stranded conductor, in which a tinned on the inside, for example made of copper contact terminal is pushed onto the end of the aluminum conductor. The tube-shaped contact terminal is tinned on the front side of the aluminum conductor by means of ultrasonic tinning together with the same or welded by means of a known welding process metallically with the same.

Bei dem Verfahren nach der DE 103 57 0418 A1 wird auf das Ende eines aus Aluminium bestehenden Litzenleiters ein Vorrat eines Kontaktierungsmittels aufgebracht und zumindest bis in den Bereich seiner Schmelztemperatur erwärmt. Dabei soll über das Kontaktierungsmittel zur Ausbildung einer elektrischen Kontaktierung eine stoffliche Verbindung zwischen dem Litzenleiter und einem gleichzeitig oder anschließend aufgeschobenen, topfartigen Kontaktelement hergestellt werden. Zum Aufbringen des Kontaktierungsmittels kann der Litzenleiter in ein Zinnbad eingetaucht werden. Dabei kann ein Teil des Litzenleiters zur Bildung einer frischen Trenn- oder Schneidfläche im Zinnbad abgetrennt oder abgeschnitten werden. Das Kontaktelement wird mit zugentlastender Wirkung um den Litzenleiter herumgepreßt.In the method of the DE 103 57 0418 A1 A supply of a contacting agent is applied to the end of a stranded conductor made of aluminum and heated at least to the region of its melting temperature. In this case, a material connection between the stranded conductor and a simultaneously or subsequently deferred, pot-like contact element is to be produced via the contacting means for forming an electrical contact. For applying the contacting agent of the stranded conductor can be immersed in a tin bath. In this case, a part of the stranded conductor can be separated or cut off in the tin bath to form a fresh separating or cutting surface. The contact element is pressed with zugentlastender effect around the stranded conductor.

Auch aus der eingangs erwähnten DE 199 08 031 B4 geht ein Verfahren hervor, mit dem ein Kontaktelement am Ende eines aus Einzeldrähten aus Aluminium bestehenden elektrischen Leiters angebracht wird. Dazu wird zunächst eine beispielsweise aus Kupfer bestehende Stützhülse um das Ende des Leiters herumgelegt und mit demselben verpreßt. Danach wird ein Kontaktelement mit der Stirnseite des Leiters so verschweißt, dass auch die Stützhülse mit erfaßt ist. Das Verschweißen kann durch einen Reibschweißvorgang realisiert werden, in welchem das Kontaktelement mit hoher Geschwindigkeit um seine Achse gedreht und gegen die Stirnseite des Leiters gedrückt wird. Dieses Verfahren erfordert für das Verschweißen von Leiter und Kontaktelement einen hohen apparativen Aufwand.Also from the aforementioned DE 199 08 031 B4 shows a method by which a contact element is attached to the end of an individual wires made of aluminum electrical conductor. For this purpose, an existing example of copper support sleeve is first placed around the end of the conductor and pressed with the same. Thereafter, a contact element with the end face of the conductor is welded so that the support sleeve is detected with. The welding can be realized by a friction welding process in which the contact element is rotated at high speed about its axis and pressed against the end face of the conductor. This method requires for the welding of conductor and contact element a high expenditure on equipment.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs geschilderte Verfahren zu vereinfachen.The invention has for its object to simplify the initially described method.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • dass nach der Festlegung der aus einem Metall auf Aluminiumbasis bestehenden Hülse am Leiter die Stirnseite desselben und das Ende der Hülse mechanisch so bearbeitet werden, dass sich eine durchgehende plane Fläche ergibt, und
  • dass auf die plane Fläche unmittelbar nach der mechanischen Bearbeitung eine geschlossene Schicht aus einem lötfähigen Material aufgetragen wird.
This object is achieved according to the invention characterized
  • that after fixing the sleeve made of an aluminum-based metal on the conductor, the end face thereof and the end of the sleeve are machined so as to give a continuous plane surface, and
  • that a closed layer of solderable material is applied to the flat surface immediately after the mechanical processing.

Bei Einsatz dieses Verfahrens wird am Ende des Leiters nach der Festlegung des als Hülse ausgeführten Kontaktelements in einem einfachen Arbeitsschritt zunächst eine plane Fläche an der Stirnseite erzeugt, in welcher auch die Hülse erfaßt ist, welche eine glatte, ebene Grundlage für das Aufbringen einer Schicht aus lötfähigem Material darstellt. Als lötfähiges Material wird insbesondere und mit Vorteil Zinn verwendet. Statt der Worte "lötfähiges Material" wird daher im Folgenden das Wort "Zinn" verwendet, stellvertretend für alle verwendbaren lötfähigen Materialien. Durch die mechanische Bearbeitung der Stirnfläche des Leiters werden dort vorhandene Oxidschichten abgetragen, so dass das auf die Stirnfläche aufgebrachte Zinn mit dem leitfähigen Material aller Einzeldrähte des Leiters verbunden wird. Ein an dem Kontaktelement und insbesondere an der Schicht aus Zinn angebrachter elektrischer Kontakt, der mit dem Zinn durch Wärmezufuhr verbunden wird, hat dementsprechend einen elektrisch leitfähigen Kontakt zum Gesamtquerschnitt des Leiters.When using this method, at the end of the conductor after the definition of the contact element designed as a sleeve in a simple step initially produces a flat surface on the front side, in which also the sleeve is detected, which is a smooth, flat basis for the application of a layer represents solderable material. The solderable material used is, in particular and advantageously, tin. Instead of the words "solderable material", the word "tin" is therefore used below, representing all usable solderable materials. Due to the mechanical processing of the end face of the conductor existing oxide layers are removed there, so that the tin applied to the end face is connected to the conductive material of all the individual wires of the conductor. An electrical contact attached to the contact element and in particular to the layer of tin, which is connected to the tin by supplying heat, accordingly has an electrically conductive contact with the overall cross section of the conductor.

Mit Vorteil und in bevorzugter Ausführungsform werden die mechanische Bearbeitung der Stirnfläche des Leiters, beispielsweise mittels eines Fräsers, und die Beschichtung derselben mit dem Zinn unter Schutzgas durchgeführt. Es kann sich dann vor dem Beschichten der Stirnfläche mit dem Zinn keine neue Oxidschicht auf der Stirnfläche des Leiters bilden. Dabei kann das Zinn beispielsweise durch Eintauchen des bearbeiteten Leiterendes in ein Zinnbad aufgebracht werden.Advantageously and in a preferred embodiment, the mechanical processing of the end face of the conductor, for example by means of a milling cutter, and the coating of the same with the tin are carried out under protective gas. It may then form no new oxide layer on the end face of the conductor before coating the end face with the tin. In this case, the tin can be applied for example by immersing the processed conductor end in a tin bath.

Das Zinn kann aber auch ohne den Einsatz von Schutzgas nach dem mechanischen Bearbeiten des Leiterendes auf dasselbe aufgebracht werden, wenn das Leiterende nach der mechanischen Bearbeitung direkt und möglichst schnell in ein Zinnbad eingetaucht wird. Eine nach dem mechanischen Bearbeiten der Stirnfläche des Leiters doch noch entstandene dünne Oxidschicht kann in dem Zinnbad mittels Ultraschalls zerstört werden, so dass das Zinn dann an der blanken Stirnfläche des Leiters haftet.The tin can also be applied to the same without the use of inert gas after mechanical processing of the conductor end when the conductor end is immersed directly and as quickly as possible in a tin bath after mechanical processing. A thin oxide layer still formed after the mechanical working of the end face of the conductor can be destroyed in the tin bath by means of ultrasound, so that the tin then adheres to the bare end face of the conductor.

Durch den Tauchvorgang des Leiterendes in ein Zinnbad bleibt gleichzeitig an der Umfangsfläche des Kontaktelements bzw. der Hülse ebenfalls Zinn haften. Durch die so erweiterte Zinnschicht kann der Kontakt zu einem an dem Kontaktelement bzw. der Hülse anzubringenden elektrischen Kontakt weiter verbessert werden.By the dipping process of the conductor end in a tin bath, tin likewise simultaneously adheres to the peripheral surface of the contact element or the sleeve. By the tin layer thus expanded, the contact with an electrical contact to be attached to the contact element or the sleeve can be further improved.

Das Verfahren nach der Erfindung wird anhand der Zeichnungen im Ausführungsbeispiel erläutert.The method according to the invention will be explained with reference to the drawings in the embodiment.

In Fig. 1 ist das Ende einer elektrischen Leitung 1 dargestellt, die einen von einer Isolierung 2 umgebenen elektrischen Leiter 3 aufweist. Der Leiter 3 ist aus einer Vielzahl von Einzeldrähten 4 aufgebaut, die aus Aluminium bestehen und vorzugsweise miteinander verseilt sind. Ein solcher Leiter wird auch als Litzenleiter bezeichnet. Die Isolierung 2 ist am Ende der Leitung 1 entfernt, so dass der Leiter 3 freiliegt.In Fig. 1 the end of an electrical line 1 is shown, which has an electrical conductor 3 surrounded by an insulation 2. The conductor 3 is constructed from a plurality of individual wires 4, which are made of aluminum and are preferably stranded together. Such a conductor is also referred to as a stranded conductor. The insulation 2 is removed at the end of the line 1, so that the conductor 3 is exposed.

Auf dem Ende des Leiters 3 ist eine als Kontaktelement vorgesehene Hülse 5 aus Aluminium angebracht. Die Hülse 5 wird durch mechanische Bearbeitung um den Leiter 3 herumgepreßt, so dass die Einzeldrähte 4 desselben fest zusammengedrückt werden und die Hülse 5 den Leiter 3 fest und lückenlos umgibt. Der Preßvorgang ist durch Pfeile 6 angedeutet. Er wird so durchgeführt, dass die Umfangsfläche der Hülse 5 auch nach dem Verpressen mit dem Leiter 3 zumindest annähernd zylindrisch ist.On the end of the conductor 3 is provided as a contact element sleeve 5 made of aluminum. The sleeve 5 is pressed around the conductor 3 by mechanical processing, so that the individual wires 4 of the same are pressed together and the sleeve 5, the conductor 3 tightly and completely surrounds. The pressing process is indicated by arrows 6. It is carried out so that the peripheral surface of the sleeve 5 is at least approximately cylindrical even after being pressed with the conductor 3.

Nach dem Verpressen der Hülse 5 mit dem Leiter 3 wird dessen Stirnfläche mechanisch bearbeitet. Das ist in Fig. 3 durch Pfeile 7 angedeutet. Dabei wird beispielsweise mittels eines Fräsers eine Schicht vom Leiterende und von der dasselbe umgebenden Hülse 5 abgetragen, so dass sich eine plane Stirnfläche ergibt. Bei diesem Vorgang werden auch Oxidschichten vom Leiterende entfernt, so dass das Aluminium der Einzeldrähte 4 metallisch blank vorliegt.After pressing the sleeve 5 with the conductor 3 whose end face is machined. Is in Fig. 3 indicated by arrows 7. In this case, for example, by means of a milling cutter, a layer is removed from the conductor end and from the sleeve 5 surrounding the same, so that a planar end surface results. In this process, oxide layers are removed from the conductor end, so that the aluminum of the individual wires 4 is present bright metallic.

Das so behandelte Leiterende wird danach in ein Zinnbad 8 (Fig. 5 und 6) eingetaucht. Es wird dadurch auf der planen Stirnfläche des Leiters 3 eine Zinnschicht 9 erzeugt, die sich entsprechend der Darstellung in Fig. 4 bis über die Umfangsfläche der Hülse 5 erstreckt. Die Zinnschicht 9 hat metallischen und damit elektrisch leitenden Kontakt zum Aluminium aller Einzelleiter 4 des Leiters 3.The thus treated conductor end is then placed in a tin bath 8 ( FIGS. 5 and 6 immersed). It is characterized on the flat end face of the conductor 3, a tin layer 9 is generated, which, as shown in FIG Fig. 4 extends beyond the peripheral surface of the sleeve 5. The tin layer 9 has metallic and therefore electrically conductive contact with the aluminum of all individual conductors 4 of the conductor 3.

Die mechanische Behandlung des Leiterendes mit dem geschilderten Abtragen einer Schicht kann mit Vorteil unter Schutzgas durchgeführt werden, so dass sich auf der erzeugten planen Stirnfläche keine neue Oxidschicht bilden kann. Die Schutzgasatmosphäre kann auch das Zinnbad 8 mit abdecken. Das Leiterende kann nach dem Erzeugen der planen Stirnfläche entsprechend Fig. 5 direkt in das Zinnbad 8 eingetaucht werden. Die Zinnschicht 9 haftet dann am Leiterende, ohne dass eine Oxidschicht entstanden ist.The mechanical treatment of the conductor end with the described removal of a layer can be advantageously carried out under protective gas, so that no new oxide layer can form on the plane generated end face. The protective gas atmosphere can also cover the tin bath 8 with. The conductor end can according to the generation of the flat end face accordingly Fig. 5 be immersed directly in the tin bath 8. The tin layer 9 then adheres to the conductor end, without an oxide layer has formed.

Wenn bei der Bearbeitung des Leiterendes kein Schutzgas eingesetzt wird, dann kann das Leiterende nach dem geschilderten Abtragen der Schicht von demselben ebenfalls direkt und möglichst schnell in das Zinnbad 8 eingetaucht werden. Das Zinnbad 8 wird bei dieser Ausführungsform des Verfahrens mit Ultraschall beaufschlagt, so dass eine eventuell doch noch auf dem Leiterende entstandene Oxidschicht zerstört und von demselben entfernt wird. Eine entsprechende Ultraschallquelle ist in Fig. 6 durch einen Pfeil 10 angedeutet. Auch so ist die Zinnschicht 9 gemäß Fig. 4 am Leiterende angebracht.If during the processing of the conductor end no inert gas is used, then the conductor end of the described removal of the layer of the same can also be immersed directly and as quickly as possible in the tin bath 8. In this embodiment of the method, the tin bath 8 is subjected to ultrasound, so that any oxide layer that may still be formed on the conductor end is destroyed and removed from it. A corresponding ultrasound source is in Fig. 6 indicated by an arrow 10. Even so, the tin layer 9 is according to Fig. 4 attached to the end of the ladder.
