Description

Die Erfindung betrifft einen system mit einem Anschluss einer elektrischen Leitung mit mehreren einzelnen elektrischen Leitern an einem Kontaktelement und mit einer Lötverbindung oder Schweißverbindung der elektrischen Leiter an dem Kontaktelement. Weiterhin betrifft die Erfindung eine elektrische Baugruppe mit einem solchen Hochstromkontakt und mit einem Gehäuse.The invention relates to a system with a connection of an electrical line with a plurality of individual electrical conductors to a contact element and with a solder joint or welded connection of the electrical conductors to the contact element. Furthermore, the invention relates to an electrical assembly with such a high current contact and with a housing.

Die DE 28 12 089 B1 offenbart ein Anschlussblech mit einem Teil zum Anschluss mindestens eines Leiters und mit Lötkämmen, an denen Lötstützpunkte angeordnet sind. Die Schraubklemmen der Leiter sind übereinander gelegt und mit dem einen Teil des Anschlussblechs verschraubt. Damit dann das über die Leiter dem Anschlussblech zugeführte Potential auf die einzelnen Lötstützpunkte verteilt werden.The DE 28 12 089 B1 discloses a connection plate with a part for connecting at least one conductor and soldering combs, at which soldering points are arranged. The screw terminals of the conductors are placed one above the other and screwed to one part of the connection plate. So that the potential supplied via the conductors to the connection plate can be distributed to the individual soldering points.

Die FR 2 471 681 offenbart ein metallisches Kontaktelement mit mehreren Anschlüssen für verschiedene Leitungen.The FR 2 471 681 discloses a metal contact element with multiple terminals for different lines.

Weiterhin ist aus der FR 2 888 679 A ein Hochstromkontakt bekannt. Bei diesem Hochstromkontakt werden die elektrischen Leiter flach auf das Kontaktelement aufgebracht und mit diesem elektrisch leitend verbunden. Die elektrisch leitende Verbindung ist anschließend von den elektrischen Leitern verdeckt.Furthermore, from the FR 2 888 679 A a high current contact known. In this high current contact, the electrical conductors are applied flat to the contact element and connected to this electrically conductive. The electrically conductive connection is then covered by the electrical conductors.

Weiterhin ist aus der US 2007/0015052 A1 ein Kontaktelement mit zwei Stutzen bekannt geworden. Die Stutzen haben unterschiedliche Durchmesser für unterschiedlich starke Leiter.Furthermore, from the US 2007/0015052 A1 a contact element with two nozzles has become known. The nozzles have different diameters for different strength ladder.

Bei einem aus der Praxis bekannten Hochstromkontakt hat das Kontaktelement einen topfförmigen Abschnitt, an dem sich eine Schraubfahne anschließt. Die Schraubfahne dient zur Verschraubung mit einer weiterführenden elektrischen Leitung. In den topfförmigen Abschnitt wird zur Montage ein Bündel der elektrischen Leiter eingeführt. Der topfförmige Abschnitt wird mit Lot ausgefüllt und damit die Lötverbindung zwischen den elektrischen Leitern und dem Kontaktelement erzeugt.In a high-current contact known from practice, the contact element has a cup-shaped section, followed by a screw flag connects. The screw flag is used for screwing with a continuing electrical line. In the pot-shaped section, a bundle of electrical conductors is inserted for mounting. The cup-shaped portion is filled with solder and thus generates the solder joint between the electrical conductors and the contact element.

Nachteilig bei den bekannten Hochstromkontakten ist, dass die Lötverbindung beispielsweise nicht auf eingeschlossene Luftblasen überprüfbar ist. Solche eingeschlossenen Luftblasen führen jedoch zu einer Beeinträchtigung der Lötverbindung, was sich im ungünstigsten Fall erst nach einiger Zeit des Betriebes des Hochstromkontaktes mit hohen Stromstärken zeigt. Die Stabilität des bekannten Hochstromkontaktes bei mechanischen Belastungen ist ebenfalls gering, da das Lot große Spalte zwischen dem Bündel der elektrischen Leiter und dem topfförmigen Abschnitt ausfüllen muss. Die großen Spalte erfordern zudem eine hohe Temperatur des Lotes. Weiterhin führt das Ausfüllen des topfförmigen Abschnitts mit Lot zu einem sehr hohen Verbrauch an dem Lot.A disadvantage of the known high current contacts is that the solder joint, for example, is not verifiable to trapped air bubbles. However, such trapped air bubbles lead to an impairment of the solder joint, which in the worst case only after some time of operation of the high-current contact with high currents shows. The stability of the known high-current contact under mechanical loads is also low because the solder must fill large gaps between the bundle of electrical conductors and the cup-shaped section. The large gaps also require a high temperature of the solder. Furthermore, the filling of the pot-shaped portion with solder leads to a very high consumption of the solder.

Bei einer Schweißverbindung von mehreren Leitern einer elektrischen Leitung besteht ebenfalls das Problem, dass nur ein Teil der Leiter mit dem Kontaktelement verbunden ist.In a welded joint of a plurality of conductors of an electrical line, there is also the problem that only a part of the conductors is connected to the contact element.

Der Erfindung liegt das Problem zugrunde, einen system der eingangs genannten Art so weiterzubilden, dass er eine zuverlässige elektrische Verbindung der elektrischen Leiter mit dem Kontaktelement ermöglicht und dass die Lötverbindung oder die Schweißverbindung überprüfbar ist. Weiterhin liegt der Erfindung das Problem zugrunde, eine elektrische Baugruppe mit einem solchen Hochstromkontakt zu schaffen, welche besonders einfach aufgebaut ist.The invention is based on the problem, a system of the type mentioned in such a way that it allows a reliable electrical connection of the electrical conductors with the contact element and that the solder joint or the welded joint is verifiable. Furthermore, the invention is based on the problem to provide an electrical assembly with such a high current contact, which is particularly simple.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass das Kontaktelement mehrere Ausnehmungen aufweist und dass die einzelnen elektrischen Leiter der einen elektrischen Leitung auf die Ausnehmungen verteilt sind.This problem is inventively solved in that the contact element has a plurality of recesses and that the individual electrical conductors of an electric line are distributed to the recesses.

Durch diese Gestaltung wird eine Bündelung aller elektrischen Leiter der elektrischen Leitung vermieden. Die elektrischen Leiter werden vielmehr auf mehrere Ausnehmungen aufgeteilt und in den Ausnehmungen verlötet. Damit wird die Gefahr einer großen Luftblase in der Verbindung zwischen dem Kontaktelement und den elektrischen Leitern vermieden. Durch die Anordnung von mehreren Ausnehmungen für die elektrischen Leiter hat das Kontaktelement im Vergleich zu einer einzigen Ausnehmung eine besonders große, den elektrischen Leitern gegenüberstehende Oberfläche. Damit führen selbst kleinere Luftblasen in den Lötverbindungen nicht zur Beeinträchtigung der Lötverbindung. Die Lötverbindung teilt sich in mehrere kleinere Lötstellen an den Ausnehmungen auf und kann daher einfach optisch überprüft werden. Bei einer Schweißverbindung führt die Aufteilung der Leiter auf den Ausnehmungen zu einer Verringerung der Gefahr, dass einige Leiter nicht mit dem Kontaktelement verbunden sind. Auch ist hierdurch die Schweißverbindung einfach überprüfbar. Ein weiterer wesentlicher Vorteil der Erfindung besteht darin, dass die Verteilung der einzelnen elektrischen Leiter auf die Ausnehmungen zu einer besonders geringen Bauhöhe des Kontaktelementes führt. Der erfindungsgemäße Hochstromkontakt lässt sich hierdurch auch besonders kompakt gestalten.By this design, a bundling of all electrical conductors of the electrical line is avoided. The electrical conductors are rather divided into a plurality of recesses and soldered in the recesses. This avoids the risk of a large bubble in the connection between the contact element and the electrical conductors. Due to the arrangement of a plurality of recesses for the electrical conductors, the contact element has a particular compared to a single recess large surface facing the electrical conductors. Thus, even smaller air bubbles in the solder joints do not affect the solder joint. The solder joint is divided into several smaller solder joints on the recesses and therefore can be easily checked visually. In a welded joint, the division of the conductors on the recesses leads to a reduction in the risk that some conductors are not connected to the contact element. Also, this makes the weld easily verifiable. Another essential advantage of the invention is that the distribution of the individual electrical conductors leads to the recesses to a particularly low height of the contact element. The high-current contact according to the invention can thus be made particularly compact.

Der erfindungsgemäße system weist eine besonders hohe mechanische Stabilität auf, wenn jeder der einzelnen elektrischen Leiter in einer eigenen Ausnehmung verlötet oder verschweißt ist. Hierdurch werden Hohlräume an dem Kontaktelement vermieden, die von Lot ausgefüllt werden müssen. Bei der Lötverbindung lässt sich der Verbrauch an Lot besonders gering halten, da das Lot erfindungsgemäß ausschließlich einzelne Lötspalte zwischen den Leitern und den Ausnehmungen ausfüllen muss.The system according to the invention has a particularly high mechanical stability when each of the individual electrical conductors is soldered or welded in a separate recess. As a result, cavities are avoided on the contact element, which must be filled by solder. In the solder joint, the consumption of solder can be kept particularly low, since the solder according to the invention must fill only individual solder gaps between the conductors and the recesses.

Die Lötverbindung oder die Schweißverbindung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach optisch überprüfen, wenn die Ausnehmungen und die elektrischen Leiter das Kontaktelement durchdringen. Durch diese Gestaltung lässt sich flüssiges Lot bei der Verlötung an einer Seite des Kontaktelementes zuführen und beobachten, wenn das Lot an dem anderen Ende des Kontaktelementes austritt. Die Beobachtung des Austretens des Lotes ist ein deutlicher Hinweis dafür, dass die Lötverbindung durchgängig ist. Die Schweißverbindung kann an einer Seite des Kontaktelementes erfolgen.According to another advantageous development of the invention, the solder connection or the welded connection can be checked optically simply when the recesses and the electrical conductors penetrate the contact element. As a result of this design, liquid solder can be supplied to one side of the contact element during soldering and observed when the solder emerges at the other end of the contact element. The observation of the leakage of the solder is a clear indication that the solder joint is consistent. The welded connection can take place on one side of the contact element.

Eine Verbindung des erfindungsgemäßen systemes mit einer weiteren elektrischen Leitung gestaltet sich besonders einfach, wenn das Kontaktelement eine Schraubseite mit einem Gewinde und eine Kontaktseite mit den Ausnehmungen zur Aufnahme der einzelnen elektrischen Leiter hat und wenn die Kontaktseite eine geringere Höhe aufweist als die Schraubseite. Vorzugsweise sind das Gewinde und die Ausnehmungen zur Aufnahme der einzelnen elektrischen Leiter parallel zueinander angeordnet.A connection of the system according to the invention with a further electrical line is particularly simple if the contact element has a screw side with a thread and a contact side with the recesses for receiving the individual electrical conductors and if the contact side has a lower height than the screw side. Preferably, the thread and the recesses for receiving the individual electrical conductors are arranged parallel to one another.

Nachbearbeitungen zur Entfernung der überstehenden Enden der elektrischen Leiter lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn das Kontaktelement auf einer Seite eben und auf der anderen Seite zur Erzeugung der unterschiedlichen Höhen der Schraubseite und der Kontaktseite stufig gestaltet ist und wenn die freien Enden der elektrischen Leiter an der stufigen Seite überstehen. Hierdurch wird zudem eine Einengung des Bereiches an dem Gewinde durch die durch das Kontaktelement hindurch geführten elektrischen Leiter vermieden.Reworking to remove the protruding ends of the electrical conductors can be easily avoided according to another advantageous embodiment of the invention, when the contact element is designed level on one side and on the other side to produce the different heights of the screw side and the contact side and if the free End of the electrical conductors on the stepped side. In this way, a narrowing of the area on the thread is avoided by the guided through the contact element electrical conductor.

Das Kontaktelement lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach auf vorgesehene Bauräume anpassen, wenn die Ausnehmungen in einer oder mehreren Reihen angeordnet sind.According to another advantageous development of the invention, the contact element can be easily adapted to intended installation spaces if the recesses are arranged in one or more rows.

Eine Korrosion der elektrischen Leiter und des Kontaktelementes lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zuverlässig vermeiden, wenn die stufige Seite der Kontaktseite mit einer aushärtenden Masse bedeckt ist. Als aushärtende Masse eignet sich vorzugsweise ein Harz.Corrosion of the electrical conductor and the contact element can be reliably avoided according to another advantageous embodiment of the invention, when the stepped side of the contact side is covered with a hardening mass. As a hardening composition is preferably a resin.

Das zweitgenannte Problem, nämlich die Schaffung einer elektrische Baugruppe mit einem vorgenannten system , welche besonders einfach aufgebaut ist, wird erfindungsgemäß dadurch gelöst, dass die stufige Seite des Kontaktelementes der Außenseite des Gehäuses zugewandt ist und wenn das Kontaktelement mit der Schraubseite aus dem Gehäuse herausragt und wenn die mit einer Lötverbindung oder einer Schweißverbindung verbundenen elektrischen Leiter vollständig innerhalb des Gehäuses angeordnet sind. Durch diese Seite wird vermieden, dass bei einer Verschraubung des Hochstromkontakts die Enden der innerhalb des Gehäuses angeordneten elektrischen Leiter bei der Verschraubung des Kontaktelementes mit einer weiterführenden Leitung stören.The second-mentioned problem, namely the creation of an electrical assembly with an aforementioned system, which is particularly simple, is inventively achieved in that the stepped side of the contact element faces the outside of the housing and when the contact element protrudes with the screw side of the housing and when the electrical conductors connected to a solder joint or a welded joint are disposed completely within the housing. Through this side it is avoided that interfere with a screw connection of the high-current contact, the ends of the arranged inside the housing electrical conductor in the screwing of the contact element with a secondary line.

Hierbei ist zu erkennen, dass wie bei der Ausführungsform nach den Figuren 2 und 3 jeweils ein elektrischer Leiter 19 in einer der Ausnehmungen 15 mittels einer Lötverbindung 20 befestigt ist.
