- a transformation of the initially round individual conductor cross-sections on honeycomb-shaped cross sections as in Figure 9 can be seen, whereby the gaps between the individual conductors are reduced.
- the compression also causes the contact sleeve 7 and the individual conductors 3 are firmly connected to each other, which greatly simplifies the further production of the connecting element according to the invention, in particular the handling of cable 4 and contact sleeve 7, so that in a next step on the front side in this stage of the process , still free end of the contact sleeve 7, a solder 12 can be inserted into the contact sleeve 7, as in Figure 6 is shown.

- the penetration depth of the solder 12 can be influenced by the design of the electrodes and their position on the contact sleeve 7 together with the soldering parameters.
- Figure 7 finally shows the pressed with the end portions 6 of the individual conductors 3 and soldered contact sleeve. 7
- connection section 14 is also converted into a connection section 14. It should again be mentioned explicitly at this point that the manner of forming, in particular the resulting geometry of this connection portion 14 of the contact sleeve 7 is flexibly selectable and can be turned off on the contact element 16 and its purpose or geometry. However, the formation of a planar connection section 14 with at least one, preferably two, planar contact surface 15a, 15b has proven to be advantageous in practice, since a versatile reference surface can be formed which facilitates the welding process, in particular in combination with projection welding.

Dabei kommen in der Praxis mittlerweile immer öfter Kupferverbindungselemente zum Einsatz, wobei darauf zu achten ist, dass die Aluminiumdrähte mit dem Kupfer nicht in direkten Kontakt kommen, um die sonst auftretende Kontaktkorrosion zu vermeiden.A challenge in the use of aluminum cables is to ensure the durable and high-performance contacting of the aluminum wires.

- Aufschmelzen des Lotes und Herstellung einer Verlötung zwischen den kontaktbauteilseitigen Endabschnitten (6) der Einzelleiter (3) sowie der Innenfläche der Kontakthülse (7)
- Umformen der Kontakthülse (7) in einem zweiten, die kontaktbauteilseitigen Endabschnitte (6) der Einzelleiter (3) überragenden Bereich
- Attaching a contact sleeve (7) on the stripped end of the cable (4) such that the contact sleeve (7) receives the contact-member side end portions (6) of the individual conductors (3) in it
- Pressing the contact sleeve (7) with the contact-component-side end sections (6) of the individual conductors (3) in a first region (8) of the contact sleeve (7)
- Introduction of heat into the pressing location (s) of the compression while at the same time supplying a solder through the contact-component-side end face of the contact sleeve (7)
- Melting of the solder and production of a soldering between the contact component-side end portions (6) of the individual conductors (3) and the inner surface of the contact sleeve (7)
- Forming the contact sleeve (7) in a second, the contact-member-side end portions (6) of the individual conductors (3) projecting area
Die Herstellung der Verlötung erfolgt erfindungsgemäß mittels Widerstandslötverfahren, wodurch das erfindungsgemäße Verbindungselement kostengünstig herstellbar ist.The preparation of the soldering is carried out according to the invention by means of Widerstandslötverfahren, whereby the connecting element according to the invention is inexpensive to produce.
Gemäß einer bevorzugten Ausführungsvariante der Erfindung werden dabei die im Widerstandslötverfahren eingesetzten Elektroden während fades Lötvorgangs im ersten Bereich der Kontakthülse aufgesetzt bzw. während des Lötvorgangs in jener Hälfte des ersten Bereichs aufgesetzt, welcher näher zu Stirnflächen der Endabschnitte verläuft, wobei die Elektroden vorzugsweise weniger als die Hälfte der Länge des ersten Bereichs überdecken. Dadurch kann sichergestellt werden, dass kein flüssiges Lot über die Kontakthülse hinaus in das Kabel und unter die Isolierung fließt, wodurch diese zerstört werden könnte.In accordance with a preferred embodiment of the invention, the electrodes used in the resistance soldering method are placed in the first region of the contact sleeve during a fade soldering operation. placed during the soldering operation in that half of the first region which is closer to end faces of the end portions, wherein the electrodes preferably cover less than half the length of the first region. This can ensure that no liquid solder flows beyond the contact sleeve into the cable and under the insulation, which could destroy it.
Die Erfindung wird nun anhand von Ausführungsbeispielen näher erläutert. Die Zeichnungen sind beispielhaft und sollen den Erfindungsgedanken zwar darlegen, ihn aber keinesfalls einengen oder gar abschließend wiedergeben.The invention will now be explained in more detail with reference to exemplary embodiments. The drawings are exemplary and are intended to illustrate the inventive idea, but in no way restrict it or even reproduce it.

Grundsätzlich ist der Anschlussabschnitt 14 beliebig umformbar und damit ausgestaltbar, so dass unterschiedlich ausgeformte Kontaktelemente 16 daran befestigbar sind. Die Form des Anschlussabschnittes 14 kann dabei an die Form des Kontaktelementes 16 angepasst werden bzw. umgekehrt. Die Ausbildung des Kontaktelementes 16 als Steckkontakt, wie im vorliegenden Ausführungsbeispiel dargestellt, ermöglich die rasche und sichere Herstellung einer elektrischen Verbindung mit dem nicht dargestellten Kontaktteil eines Verbrauchers.In principle, the
Das Kabel 4 ist dabei mit einer Isolierung 2 versehen, die mehrere Einzelleiter 3 umgibt. Die Einzelleiter 3 sind als Drähte oder Litzen ausgeführt und aus einem Leichtmetall, im vorliegenden Ausführungsbeispiel Aluminium oder einer Aluminiumlegierung gefertigt. Das in
Die Kontakthülse 7 besteht aus Kupfer oder einer Kupferlegierung und ist mit einer Nickelbschichtung 10 an ihrer Innenseite versehen, um einen direkten Kontakt zwischen Aluminiumleiter 3 und Kontakthülse 7 zu verhindern und damit Kontaktkorrosion zu vermeiden.The
Die Kontakthülse 7 ist in dem weiter oben bereits erwähnten ersten Bereich 8 mit den Endabschnitten 6 der Einzelleiter 3 verpresst. Durch die damit einhergehende Querschnittsverengung der Kontakthülse 7 kommt es in den Randbereichen 21 des ersten Bereichs 8 zu einem Formschluss zwischen der Kontakthülse 7 und den Endabschnitten 6.The
Zusätzlich sind Endabschnitte 6 der Einzelleiter 3 in ihren Endbereichen und stirnseitig miteinander und mit der Kontakthülse 7 verlötet. Dabei ist die die Verpressung bewirkende Presskraft im ersten Bereich 8 derart gewählt, dass zwischen den Einzelleitern 3 ausreichend Platz bleibt, so dass das flüssige Lot 12 in diese Zwischenräume eindringen kann. Gleichzeitig ist der Zwischenraum aber so gering gehalten, dass das flüssige Lot 12 das Kabel nicht in Richtung Isolierung 2 bzw. über die Isolierung 2 hinweg rinnen kann. Derart entsteht eine Verlötung, welche sowohl die Stirnflächen der Einzelleiter 3 überdeckt, als auch die Zwischenräume zwischen den Einzelleitern 3 entlang eines Teils der Endabschnitte 6, sowie die Innenfläche der Kontakthülse 7 in diesem Bereich.In addition,
Der über die Stirnflächen der Endabschnitte 6 überstehende Abschnitt der Kontakthülse 7 ist in einem zweiten Bereich 9 nach Fertigstellung der Lötung zu einem Anschlussabschnitt 14 umgeformt. Im vorliegenden Ausführungsbeispiel führt die Umformung dazu, dass sich zwei ebene Kontaktflächen 15a,15b ausbilden. An eine dieser Kontaktflächen 15a,15b ist das weitere oben bereits beschriebene Steckkontaktelement 16 befestigt, konkret, angeschweißt und zwar mittels Buckelschweißverfahren, wobei die dafür vorgesehenen Buckel mit 22 gekennzeichnet sind. Die Verformung führt auch dazu, dass die Lötstelle im Inneren der Hülse von äußeren Einflüssen weitgehend abgeschirmt werden kann, insbesondere dann, wenn in einer bevorzugten Ausführungsvariante der Erfindung die innere Nickelbeschichtung 10 der Kontakthülse 7 mit einer weiteren Schicht aus Zinn beschichtet ist. In diesem Fall würde sich durch die Buckelschweißung im Anschlussabschnitt 14 im zweiten Bereich der Kontakthülse 7, also dort wo diese umgeformt ist, auf der Innenseite der Kontakthülse 7 durch den Schweißvorgang eine gasdichte Sperrschicht ausbilden.The over the end faces of the
