Description

Die Erfindung betrifft ein Verfahren zum Verbinden eines massiven Metallstückes, insbesondere einer Metallschiene aus Kupfer oder Aluminium, die beispielsweise mit einer Leiterplatte verbunden ist, mit einem flexiblen Metallband, beispielsweise einer Kupferlitze oder einem Masseband aus Kupfer.The invention relates to a method for connecting a solid metal piece, in particular a metal rail made of copper or aluminum, which is connected for example to a printed circuit board, with a flexible metal strip, such as a copper wire or a ground strap made of copper.

In der Kraftfahrzeugelektronik fließen aufgrund der geringen Bordnetzspannung und trotzdem geforderter höherer Leistungen Ströme, die einige zehn Ampere bis über 100 Ampere betragen können. Hierfür sind Leitungen mit entsprechend großem Querschnitt erforderlich, um den Widerstand der Leitungen und die damit verbundene Erwärmung gering zu halten. Außerdem stellt sich das Problem, solche Leitungen miteinander zu verbinden. Aufgrund der hohen Ströme müssen die Verbindungen einerseits großflächig sein und außerdem über eine lange Zeit beständig und korrosionsfrei bleiben. Daher werden die Metallleitungen zumeist miteinander verschweißt, um diese Anforderungen erfüllen zu können.In the automotive electronics flow due to the low vehicle electrical system voltage and still required higher power currents, which can be several tens of amps to over 100 amps. For this purpose, lines with a correspondingly large cross section are required to keep the resistance of the lines and the associated heating low. In addition, there is the problem of connecting such lines with each other. Due to the high currents, the compounds must be both large-scale and also remain resistant and corrosion-free over a long time. Therefore, the metal lines are usually welded together to meet these requirements.

Die DE 10 2004 015 128 A1 offenbart eine Kontaktierungsvorrichtung, die einen Draht umfasst, vorzugsweise aus Kupfer, und ein Kontaktelement. Der Draht ist massiv, d. h. es handelt sich nicht um eine Litze mit mehreren dünnen Drähten. Vorzugsweise ist der Draht starr. Dies bedeutet, dass der Draht eine Form, in die er gebogen wird beibehält, wobei natürlich eine gewisse minimale Flexibilität vorhanden ist. Der Draht ist mit einer Lackschicht isoliert. An wenigstens einem Drahtende weist der Draht einen Crimpbereich auf. Die Lackschicht des Crimpbereichs ist vollständig entfernt. Das Kontaktelement hat vorzugsweise einen zylindrischen Steckkontakt und einen sich daran anschließenden Crimpabschnitt. Der Crimpabschnitt hat die Form einer Hülse und weist ein Innengewinde auf. Der Crimpabschnitt umgreift den Crimpbereich des Drahtendes und ist gequetscht. Dadurch dringen die Erhöhungen des Innengewindes in die Oberfläche des Crimpbereichs ein.The DE 10 2004 015 128 A1 discloses a contacting device comprising a wire, preferably copper, and a contact element. The wire is solid, ie it is not a strand with several thin wires. Preferably, the wire is rigid. This means that the wire retains a shape to which it is bent, with, of course, some minimal flexibility. The wire is insulated with a varnish layer. At least one wire end, the wire has a crimping area. The lacquer layer of the crimping area is completely removed. The contact element preferably has a cylindrical plug contact and an adjoining crimp section. The crimp section is in the form of a sleeve and has an internal thread. The crimping section engages around the crimping area of the wire end and is crushed. As a result, the elevations of the internal thread penetrate into the surface of the crimping area.

Diese bekannten Verbindungstechniken sind jedoch einerseits aufwendig und führen andererseits dazu, dass die Dicke der Verbindungsstelle größer ist als die Dicke des Metallstückes, was häufig unerwünscht ist.However, these known connection techniques are on the one hand consuming and on the other hand lead to the fact that the thickness of the joint is greater than the thickness of the metal piece, which is often undesirable.

Die Aufgabe vorliegender Erfindung ist es daher, diese Nachteile zu vermeiden.The object of the present invention is therefore to avoid these disadvantages.

Die Aufgabe wird durch ein Verfahren zum Verbinden eines massiven Metallstückes mit einem flexiblen Metallband gelöst, bei dem zunächst in dem Metallstück eine Öffnung angebracht wird, in die anschließend das Metallband eingeführt wird. Danach wird das Metallstück derart verpresst, dass das Metallband mit dem Metallstück formschlüssig verbunden wird und die Verbindungsstelle und das Metallstück nahezu die gleiche Dicke aufweisen.The object is achieved by a method for connecting a solid metal piece to a flexible metal strip, in which first an opening is made in the metal piece, into which the metal strip is then inserted. Thereafter, the metal piece is pressed so that the metal strip is positively connected to the metal piece and the joint and the metal piece have almost the same thickness.

Die Innenseite der Öffnung kann in vorteilhafter Weiterbildung vor dem Einführen des Metallbandes strukturiert werden.The inside of the opening can be structured in an advantageous development prior to insertion of the metal strip.

Das Anbringen der Öffnung in dem Metallstück kann in vorteilhafter Weise durch Schlitzen und Aufspreizen eines Endes des Metallstücks erfolgen.The attachment of the opening in the metal piece can be done advantageously by slitting and spreading one end of the metal piece.

Durch das erfindungsgemäße Verfahren kann auf einfache Weise eine beständige und sichere Verbindung zwischen einem Metallstück und einem Metallband hergestellt werden, wobei die Dicke der erhaltenen Verbindungsstelle nicht größer ist als die des Metallstückes.By the method according to the invention can be easily produced a stable and secure connection between a metal piece and a metal strip, wherein the thickness of the obtained joint is not greater than that of the metal piece.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels mit Hilfe von Figuren näher erläutert.The invention will be explained in more detail using an exemplary embodiment with the aid of figures.

Dabei zeigen:Showing:

2 die erfindungsgemäß fertig gestellte Verbindungsstelle. 2 the inventively completed joint.

1 zeigt ein Metallstück 1, das beispielsweise eine mit einer Leiterplatte verbundene Kontaktfahne für Hochstromverbindungen sein kann. Für das Material des Metallstückes 1 kommen alle üblichen Metalle wie Kupfer und Aluminium in Frage. Am Ende des Metallstückes 1 ist eine Öffnung 3 angebracht, die zwei Schenkel 4 beispielsweise durch Aufspreizen eines zuvor angebrachten Schlitzes entstehen lässt. Die Öffnung 3 kann sich dabei über die gesamte Breite des Metallstückendes 1 erstrecken, jedoch ebenso nur in einem Abschnitt des Metallstückendes 1 angebracht sein. 1 shows a piece of metal 1 which may be, for example, a contact lug for high current connections connected to a printed circuit board. For the material of the metal piece 1 All common metals such as copper and aluminum come into question. At the end of the piece of metal 1 is an opening 3 attached, the two thighs 4 for example, by spreading open a previously attached slot. The opening 3 can be over the entire width of the metal piece end 1 extend, but also only in a portion of the metal piece end 1 to be appropriate.

In die Öffnung 3 ist ein Metallband 2 eingeführt, wobei sowohl ein massives, jedoch biegsames Metallband als auch ein Geflecht oder eine Litze in Frage kommen. Im aufgespreizten Zustand weist die spätere Verbindungsstelle 6 eine größere Dicke auf, als das Metallstück 1.In the opening 3 is a metal band 2 Both a solid but flexible metal band as well as a braid or a strand are possible. In the spread state, the later connection point 6 a greater thickness than the piece of metal 1 ,

In vorteilhafter Ausbildung der Erfindung kann die Innenseite der Öffnung 3 Strukturen aufweisen, um einen besseren Formschluss des Metallstücks 1 mit dem Metallband 2 zu erreichen.In an advantageous embodiment of the invention, the inside of the opening 3 Have structures to better fit the metal piece 1 with the metal band 2 to reach.

1 zeigt zwei Stempel 5, mit deren Hilfe das Metallstück 1 mit dem Metallband 2 verpresst wird, bis die Verbindungsstelle 6 die gleiche Dicke aufweist wie das Metallstück 1. Diesen Endzustand der Verbindungsstelle 6 zeigt die 2, die erkennen lässt, dass auf einfache Weise eine saubere und beständige Verbindung der beiden Teile erreicht werden kann. 1 shows two stamps 5 , with the help of which the piece of metal 1 with the metal band 2 is pressed until the junction 6 the same thickness like the piece of metal 1 , This final state of the junction 6 show the 2 , which shows that a simple and clean connection between the two parts can be achieved.
