Abstract

The invention addresses the problem of aluminum and in particular stranded aluminum wires, which generally do not well bond to other metals such as e.g. copper or brass. In the long term, the transition resistance changes, in particular under the influence of oxygen and due to the energizing with high currents. There is also a need for high-current connectors that can be flexibly strapped and field-wired. The invention relates to a heavy-duty plug-type connector having at least one crimp contact (1), the transition (10) between a crimping region (11) that consists of aluminum and a contact region (12) that consists of copper being shifted to the cylindrical or at least rotationally symmetric crimp contact (1). The stranded wire can thus be crimped with the crimp contact (1) without the aforementioned problems. Furthermore, an additional inner thread (112) and a pin (113) that the can screwed into it are provided in the crimping region (11).

Derartige Steckverbinder und Kontakte werden eingesetzt, um zwischen elektrischen Leitern einen elektrischen Strom mit Stromstärken von beispielsweise 500 bis 650 A zu übertragen. Such connectors and contacts are used to transfer between electrical conductors an electric current with currents of, for example, 500 to 650 A.
Stand der Technik State of the art
Im Stand der Technik ist es bekannt, sowohl Kupferleitungen als auch Aluminiumleitungen zur elektrischen Energieübertragung insbesondere im Hochstrom bereich zu verwenden. Beispielsweise wurde seinerzeit in der DDR zu diesem Zweck vorwiegend Aluminium als verfügbarer Rohstoff eingesetzt. Meist geschah dies in Form relativ starrer Einzelleiter, so dass auch heutzutage in den neuen Bundesländern derartige Energieversorgungsleitungen anzutreffen sind. Dagegen wurden im den alten Bundesländern in der Vergangenheit vorwiegend Litzenleiter aus Kupfer verwendet. Aufgrund der aktuellen Preise und der nur in begrenztem Maße zur Verfügung stehenden Kupferressourcen und weiterhin auch aufgrund des deutlich geringeren spezifischen Gewichtes (AL: 2,73 Kg/dm3 ; CU: 8,9 Kg/dm3) wird heutzutage in vielen Bereichen zunehmend Aluminium als Material für elektrische Hochstromübertragungsleitungen verwendet. Dabei werden bevorzugt die flexibleren, d.h. weniger starren, Litzenleiter eingesetzt. Die Stromübertragung kann dabei sowohl im überirdischen Bereich, z.B. in Windkraftanlagen sowie im Bereich der Eisenbahn, aber auch bei der unterirdischen Energieverteilung, z.B. in Form von Erdleitungen als Bestandteil eines größeren Stromverteilungsnetzes, stattfinden. Der etwas geringere spezifische Leitwert von Aluminium und die daraus resultierenden entsprechend größeren notwendigen Kabelquerschnitte werden zugunsten der vorgenannten Vorteile in Kauf genommen. In the prior art it is known to use both copper cables and aluminum cables for electrical energy transmission, in particular in the high-current area. For example, at that time in the GDR for this purpose predominantly aluminum was used as available raw material. Most of this happened in the form of relatively rigid individual conductors, so that even today in the new federal states such energy supply lines are to be found. By contrast, copper stranded conductors were predominantly used in the old federal states in the past. Due to the current prices and the limited availability of copper resources and also due to the significantly lower specific gravity (AL: 2.73 Kg / dm 3 , CU: 8.9 Kg / dm 3 ) is increasing in many areas today Aluminum used as material for high current electrical transmission lines. In this case, the more flexible, ie less rigid, stranded conductors are preferably used. The power transmission can take place both in the above-ground area, for example in wind turbines and in the railway, but also in the subterranean energy distribution, eg in the form of ground lines as part of a larger power distribution network. The slightly lower specific conductivity of aluminum and the resulting correspondingly larger necessary cable cross sections are accepted in favor of the aforementioned advantages.
Der zunehmende Einsatz von Aluminiumkabeln in Windkraftanlagen ist in der Druckschrift WO 2013 174 581 A1 erwähnt. Weiterhin ist der Einsatz von elektrischen Verbindern zum elektrischen Verbinden von verschiedenen Kabeln beschrieben. Es wird der Einsatz von Crimp- und Schraubverbindungen erwähnt. Um die Nachteile durch die Oxydierung am Übergang der Aluminiumlitzen zum Verbindungsstück zu vermeiden, wird vorgeschlagen, die Kabel an den Anschlussflächen des Verbindungsstücks anzuschweißen, z.B. durch Reibschweißen. The increasing use of aluminum cables in wind turbines is mentioned in document WO 2013 174 581 A1. Furthermore, the use of electrical connectors for electrically connecting different cables is described. The use of crimp and screw connections is mentioned. To avoid the disadvantages of oxidation at the junction of the aluminum strands to the connector, it is proposed to weld the cables to the mating surfaces of the connector, e.g. by friction welding.
Weiterhin wird erwähnt, dass die Verbindung zwischen dem Aluminiumkabel und dem Verbindungsstück durch Reibschweißen, Rotationsreibschweißen, Ultraschallschweißen oder Widerstandsschweißen stattfinden kann. Das Verbindungsstück kann aus Kupfer gebildet sein. Alternativ dazu wird offenbart, dass das Verbindungsstück ebenfalls aus Aluminium gebildet ist, um Übergangswiderstände oder Kontaktkorrosionen an den Übergängen zwischen dem Aluminiumkabel und dem Kontaktstück zu vermeiden. Ferner wird ein Verzinnen oder ein Verzinnen und Vernickeln der Oberfläche der Verbindungsstücke vorgeschlagen. Furthermore, it is mentioned that the connection between the aluminum cable and the connector can take place by friction welding, rotary friction welding, ultrasonic welding or resistance welding. The connector may be formed of copper. Alternatively, it is disclosed that the connector is also formed of aluminum to provide contact resistances or contact corrosion at the junctions between the aluminum cable and the connector To avoid contact piece. Further, tinning or tinning and nickel plating of the surface of the connectors is proposed.
Aus der Druckschrift DE 10 2013 105 669 A1 ist es ebenfalls bekannt, elektrische Verbinder mit einem Litzenleiter durch Widerstandsschweißen zu verbinden. From DE 10 2013 105 669 A1 it is also known to connect electrical connectors to a stranded conductor by resistance welding.
Die Druckschrift EP 1 032 077 A2 schlägt in diesem Zusammenhang vor, einen Litzenleiter aus Aluminium durch Reibschweißen mit einem Kontaktteil aus Kupfer zu verbinden. The document EP 1 032 077 A2 proposes in this connection to connect a stranded conductor made of aluminum by friction welding to a contact part made of copper.
Die Druckschrift EP 2 621 022 A1 beschreibt einen Kabelschuh zum Verbinden eines stromführenden Elements mit einem Aluminiumkabel, wobei ein erster Abschnitt eines dazugehörigen Rohrs an einer Innenseite eine Aluminiumschicht und an einer Außenseite eine Kupferschicht aufweist. Document EP 2 621 022 A1 describes a cable lug for connecting a current-carrying element to an aluminum cable, wherein a first section of an associated tube has an aluminum layer on one inner side and a copper layer on an outer side.
EP 2 662 934 A2 schlägt die Verwendung einer aus Aluminium oder aus einer Aluminiumlegierung bestehenden Verbindungskappe vor. Diese Verbindungskappe wird mit dem Aluminiumleiter verpresst und an das aus Kupfer oder einer Kupferlegierung bestehende Kontaktteil geschweißt. EP 2 662 934 A2 proposes the use of a connecting cap made of aluminum or of an aluminum alloy. This connection cap is pressed together with the aluminum conductor and welded to the existing of copper or a copper alloy contact part.
Grundsätzlich ist die Konfektionierung bei diesen Bauformen, bei denen also der Litzenleiter an den Kontakt direkt oder indirekt angeschweißt wird, leider sehr aufwändig und kann nicht ohne entsprechende Geräte vor Ort vorgenommen werden, so dass bei diesem Bauformen keine Feldkonfektionierbarkeit gegeben ist. Basically, the assembly in these types, in which the stranded conductor is welded directly or indirectly to the contact, unfortunately, very expensive and can not be done without appropriate equipment on site, so that in these designs no Feldauffektionierbarkeit is given.
Die DE 1 1 201 1 103 392 T5 offenbart einen Crimp-Anschluss, der aus zwei verschiedenen Metallwerkstoffen, z.B. Kupfer und Aluminium, be- steht. Der Verbindungsbereich dieser beiden Materialien ist zur Korrosionsvermeidung mit einem Kunststoffformteil bedeckt. DE 1 1 201 1 103 392 T5 discloses a crimp connection made of two different metal materials, eg copper and aluminum. stands. The connection region of these two materials is covered with a plastic molding for corrosion prevention.
Die Druckschrift EP 2 579 390 A1 beschreibt ebenfalls ein Aluminium- Kupfer-Terminal, das ein Kontaktteil aus Aluminium und eine Anschlussteil aus Kupfer besitzt, welche miteinander verschweißt sind, wobei der Verbindungsbereich durch Anbringen einer Primärdichtung, z.B. durch ein Umspritzen mit einem speziellen Thermoplast, gegen Elektrokorrosion geschützt ist, wobei die Litze an das Kontaktteil angeschweißt wird. Document EP 2 579 390 A1 also describes an aluminum-copper terminal having an aluminum contact part and a copper connector part which are welded together, the connecting portion being formed by attaching a primary seal, e.g. protected against electrocorrosion by overmolding with a special thermoplastic, whereby the strand is welded to the contact part.
Somit wird in diesen beiden letztgenannten beiden Druckschriften vorgeschlagen, den betreffenden Übergangsbereich mit einer Dichtung, beispielsweise durch ein Umspritzen mit einem speziellen Thermoplast, abzudichten. Doch zum einen ist dieser Vorgang aufwändig, und zum anderen besitzt eine solche Dichtung üblicherweise eine nur begrenzte Lebensdauer. Ein so gebildeter Verbinder ist nicht als Kontaktelement für einen Steckverbinder geeignet. Thus, it is proposed in these two last two documents to seal the respective transition region with a seal, for example by overmolding with a special thermoplastic. But on the one hand, this process is complex, and on the other hand, such a seal usually has a limited life. A connector thus formed is not suitable as a contact element for a connector.
Die vorgenannten Druckschriften beziehen sich weiterhin auf Verbinder, mit denen ein Versorgungskabel an eine Stromschiene oder an ein anderes Kabel dauerhaft zur Festinstallation angeschlossen wird. Diese Installation wird also einmal montiert und ist grundsätzlich nicht dafür vorgesehen, des Öfteren geändert zu werden. The aforementioned publications also relate to connectors with which a supply cable is permanently connected to a power rail or to another cable for permanent installation. This installation is therefore mounted once and is not intended to be changed frequently.
Im Gegensatz dazu sind im Stand der Technik, beispielsweise aus der Druckschrift EP 892 462 B1 , auch elektrische Schwerlaststeckverbinder bekannt, die Krimpkontakte aufweisen, und deren Kabelanschlusstechnik dadurch deutlich einfacher ist. In contrast, in the prior art, for example from the document EP 892 462 B1, electrical heavy-duty connectors are also known which have crimp contacts, and their cable connection technology is thereby significantly simpler.
Auch dabei bleibt jedoch das Problem bestehen, dass die Litzen des Aluminiumleiters untereinander aufgrund ihrer Oxydierung eine schlech- te sogenannte„Querleitfähigkeit" (d.h. die Leitfähigkeit zwischen den einzelnen Litzen senkrecht zum Verlauf des Kabels) aufweisen, was ebenfalls bei sämtlichen beschriebenen Anordnungen den Übergangswiderstand zum Anschlusskontakt vergrößert. However, there is still the problem that the strands of the aluminum conductor have a bad bond between them due to their oxidation. te so-called "transverse conductivity" (ie, the conductivity between the individual strands perpendicular to the course of the cable), which also increases the contact resistance to the terminal contact in all described arrangements.
Weiterhin besteht weiterhin das Problem, dass Aluminium leicht oxydiert und sich weiterhin mit anderen Metallen wie z.B. Kupfer oder Messing schlecht verbindet. Insbesondere gilt dies aufgrund ihrer großen Oberfläche für Aluminium-Litzenleiter. Im Übergangsbereich zwischen Aluminium und beispielsweise Kupfer entsteht insbesondere unter einer langfristigen Bestromung mit hohen Stromstärken und unter gleichzeitigem Sauerstof- feinfluss eine sogenannte„Elektrokorrosion", und damit eine Schicht, die einen wesentlich höheren spezifischen Widerstand besitzt als jedes der beteiligten Metalle. Durch diesen hohen Widerstand kann im Betrieb aufgrund der hohen Stromstärken eine starke Erwärmung stattfinden, durch die sich dieser Übergangswiderstand in Form einer Wechselwirkung zusätzlich erhöht. Diese Wärmeentwicklung kann außerdem weitere Folgeschäden, beispielsweise an einer Kunststoffisolierung, nach sich ziehen. Furthermore, there is still the problem that aluminum is easily oxidized and continues to react with other metals such as e.g. Copper or brass badly connects. This is especially true due to its large surface area for aluminum stranded conductors. In the transition region between aluminum and, for example, copper, so-called "electrocorrosion" is produced, in particular under long-term current supply with high currents and with simultaneous oxygen flow, and thus a layer which has a much higher specific resistance than any of the metals involved In operation, due to the high current intensities, a high degree of heating may take place, which additionally increases this contact resistance in the form of an interaction.
Beispielsweise im Bereich der Eisenbahn, aber auch in vielen anderen Bereichen, gibt es Anwendungen, die eine häufige Änderung der elektrischen Hochstromverkabelung erfordern. Somit existiert im Stand der Technik ein Bedarf an flexibel rangierbaren Hochstromverbindern, die bevorzugt feldkonfektionierbar oder zumindest mit möglichst geringem Aufwand konfektionierbar sind. For example, in the field of railways, but also in many other areas, there are applications that require frequent change of high-voltage electrical wiring. Thus, there exists in the prior art a need for flexibly assignable high-current connectors, which are preferably field-assemblable or at least can be assembled with the least possible outlay.
Aufgabenstellung task
Die Aufgabe der Erfindung besteht somit darin, einen elektrischen Verbinder anzugeben, der einerseits ein vergleichsweise unaufwändiges Anschließen eines Aluminium-Litzenleiters gestattet, der andererseits auch ein möglichst flexibles Rangieren ermöglicht und der weiterhin auch bei über einen langen Zeitraum wirkenden hohen Stromstärken eine nachhaltig gute elektrische Leitfähigkeit aufweist. The object of the invention is therefore to provide an electrical connector, on the one hand allows a comparatively inexpensive connection of an aluminum stranded conductor, on the other hand also allows the most flexible maneuvering and continues to have a sustainable good electrical conductivity even when acting over a long period of high currents.

In einem zweiten Aspekt wird die Aufgabe mit einem Herstellungsverfahren der eingangs erwähnten Art durch die Merkmale des kennzeichnenden Teils des unabhängigen Nebenanspruchs 9 gelöst. In a second aspect, the object is achieved by a manufacturing method of the type mentioned by the features of the characterizing part of the independent subclaim 9.
In einem dritten Aspekt wird die Aufgabe mit einem Anwendungsverfahren der eingangs erwähnten Art durch die Merkmale des kennzeichnenden Teils des unabhängigen Nebenanspruchs 14 gelöst.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous embodiments of the invention are specified in the subclaims.
Bei der Erfindung handelt es sich gemäß dem ersten Aspekt um einen Schwerlaststeckverbinder mit mindestens einem Crimpkontakt, wobei der Crimpkontakt einen aus Aluminium oder einer Aluminiumlegierung gebildeten Crimpbereich und einen dran angrenzenden, aus Kupfer oder aus einer Kupferlegierung gebildeten Kontaktbereich aufweist, wobei der Kontaktbereich Stift- oder Buchsenförmig ausgeführt sein kann. Somit kann ein Aluminium-Litzenleiter mit dem Crimpbereich vercrimpt werden, ohne dass dadurch eine sogenannte„Elektrokorrosion" entsteht. The invention in the first aspect is a heavy duty connector having at least one crimp contact, the crimp contact having a crimping region formed of aluminum or an aluminum alloy and a contact region formed of copper or copper alloy adjacent thereto, the contact region being pin or pin Can be designed socket-shaped. Thus, an aluminum stranded conductor can be crimped with the crimp without causing so-called "electrocorrosion".
Der Übergang vom Kupfer- zum Aluminiummaterial ist dazu erfindungsgemäß in den Crimpkontakt hinein verlegt. Dies wird ermöglicht, indem der Crimpbereich mit dem Kontaktbereich verschweißt ist. Insbesonde- re wird diese Verbindung bei der Herstellung des Crimpkontaktes durch einen Reibschweißvorgang hergestellt. The transition from copper to aluminum material according to the invention is moved into the crimp contact. This is made possible by the crimping area is welded to the contact area. Insbesonde- In the manufacture of the crimp contact, this connection is produced by a friction welding process.
Bei dem Crimpkontakt kann es sich also um einen hochstromfähigen Kontaktstift oder eine hochstromfähige Kontaktbuchse handeln. Mindestens ein solcher Kontaktstift und/oder eine solche Kontaktbuchse sind in einen Isolierkörper eingeführt und bilden mit diesem zusammen einen Bestandteil des Schwerlaststeckverbinders. The crimp contact can therefore be a high-current-capable contact pin or a high-current-capable contact socket. At least one such contact pin and / or such a contact socket are inserted into an insulating body and together with this form part of the heavy duty connector.
Es ist von besonderem Vorteil, dass der Crimpkontakt zumindest bereichsweise rotationssymmetrisch ausgebildet ist oder zumindest einen oder mehrere Bereiche mit einer zylinderförmigen oder zumindest rotationssymmetrischen Außenkontur besitzt, weil er dadurch formschlüssig in Durchgangsbohrungen oder entsprechenden ebenfalls rotationssymmetrischen Durchgangsöffnungen des Isolierkörpers angeordnet sein kann. It is of particular advantage that the crimp contact is at least partially rotationally symmetrical or has at least one or more areas with a cylindrical or at least rotationally symmetric outer contour, because it can thereby be arranged positively in through holes or corresponding likewise rotationally symmetrical through holes of the insulating.
Es ist weiterhin vorteilhaft, bei der Herstellung, gemäß dem zweiten Aspekt der Erfindung, Aluminium aufgrund seiner leichten Verformbarkeit als Material für den Crimpbereich des Crimpkontaktes zu verwenden. Dies ist zur Vercrimpung eines Aluminiumleiters, insbesondere eines Aluminium-Litzenleiters, besonders vorteilhaft, weil dabei an dem betreffenden Bereich trotz dem unvermeidlichen Kontakt mit Sauerstoff keine Elektrokorrosion und insbesondere auch keine intermetallische Phase entsteht. It is also advantageous, in the manufacture according to the second aspect of the invention, to use aluminum as the material for the crimping area of the crimp contact due to its easy deformability. This is particularly advantageous for crimping an aluminum conductor, in particular an aluminum stranded conductor, because in this case, despite the inevitable contact with oxygen, no electrocorrosion and, in particular, no intermetallic phase are produced at the area concerned.
Zur Aufnahme des Aluminium-Litzenleiters besitzt der Crimpbereich einen Hohlraum mit einer Kabeleinführöffnung. For receiving the aluminum stranded conductor, the crimping region has a cavity with a cable insertion opening.
Weiterhin kann in den Crimpkontakt anschließend an den Hohlraum eine zusätzliche Durchgangsbohrung gebohrt und in diese Durchgangsöffnung kann ein Innengewinde geschnitten werden. Über dieses Innengewinde kann gemäß dem dritten Aspekt der Erfindung ein Dorn, welcher ein dazu passendes Außengewinde sowie daran anschließend eine Spitze aufweist, mit seiner Spitze voran in den Hohlraum, bevorzugt in Richtung der Kabeleinführöffnung, also entgegen der Einführrichtung des Litzenleiters, eingeschraubt werden. Furthermore, an additional through-hole can be drilled in the crimp contact following the cavity, and an internal thread can be cut into this through-opening. About this internal thread can according to the third aspect of the invention, a mandrel, which has a matching external thread and then a tip, with its tip first in the cavity, preferably in the direction of Kabeleinführöffnung, ie against the insertion of the stranded conductor, are screwed.
Dadurch werden die Litzen des zuvor eingeführten Aluminium- Litzenleiters von Innen gegen den Crimpbereich gepresst. Vorteilhafterweise besitzt der Crimpkontakt innerhalb seines Crimpbereichs ein zusätzliches Innengewinde, dann wird der Litzenleiter von innen gegen dieses zusätzlliche Innengewinde gepresst, wobei das zusätzliche Innengewinde durch die erhöhte Reibkraft die Litzen hält. Weiterhin wird die Oxydschicht der Aluminiumlitzen aufgebrochen. Dadurch und durch den Druck gegeneinander nimmt die Querleitfähigkeit des Litzenleiters zu. Somit verringert sich der Übergangswiderstand zwischen dem Litzenleiter und dem Crimpkontakt. Auch nach dem Vercrimpen ist durch den Einsatz des Dorns die Leitfähigkeit nachhaltig verbessert, insbesondere, wenn der Dorn bevorzugt aus Aluminium oder auch einem anderen elektrisch leitfähigen Material, beispielsweise einer Kupferlegierung besteht und sich dadurch die Kontaktfläche des Crimpkontakts gegenüber dem Litzenleiter erhöht. As a result, the strands of the previously introduced aluminum stranded conductor are pressed from the inside against the crimping area. Advantageously, the crimp contact has an additional internal thread within its crimping range, then the stranded conductor is pressed from the inside against this additional internal thread, the additional internal thread holding the strands by the increased frictional force. Furthermore, the oxide layer of the aluminum strands is broken. This and the pressure against each other increases the transverse conductivity of the stranded conductor. Thus, the contact resistance between the stranded conductor and the crimp contact decreases. Even after crimping, the conductivity is sustainably improved by the use of the mandrel, in particular if the mandrel is preferably made of aluminum or else another electrically conductive material, for example a copper alloy, thereby increasing the contact surface of the crimp contact with respect to the stranded conductor.
Bei der Herstellung ist es vorteilhaft, wenn der Innenradius des zylindrischen Hohlraums größer ist als der theoretische Innenradius des hineingeschnittenen zusätzlichen Innengewindes, so dass das in den Hohlraum hineinragende zusätzliche Innengewinde abgeflacht ist. Dies ist besonders vorteilhaft, weil dadurch einerseits zwei gewünschte Effekte des zusätzlichen Innengewindes erhalten bleiben, nämlichIn the production, it is advantageous if the inner radius of the cylindrical cavity is greater than the theoretical inner radius of the cut additional internal thread, so that the protruding into the cavity additional internal thread is flattened. This is particularly advantageous because, on the one hand, two desired effects of the additional internal thread are retained, namely
1 . ) dass die Oxydschicht der Aluminiumlitzen aufgebrochen wird, und1 . ) that the oxide layer of the aluminum strands is broken, and
2. ) dass der Litzenleiter entgegen seiner Einführrichtung mit besonders guter Reibwirkung im Hohlraum gehalten ist, aber dass andererseits 3.) die Litzen nicht beschädigt werden. Zum dritten Punkt ist es weiterhin besonders vorteilhaft, wenn die reale Tiefe des abgeflachten Gewindes kleiner ist als der Durchmesser der Litzen, so dass das Gewinde die Litzen nicht durchtrennen kann. 2.) that the stranded conductor is held contrary to its insertion with particularly good friction in the cavity, but that on the other 3.) the strands are not damaged. For the third point, it is furthermore particularly advantageous if the real depth of the flattened thread is smaller than the diameter of the strands, so that the thread can not cut through the strands.
Aufgrund seiner Stabilität und seiner guten elektrischen Leitfähigkeit ist es ist vorteilhaft, Kupfer als Material für den Kontaktbereich einzusetzen. In einer vorteilhaften Ausgestaltung ist der Kontaktbereich zusätzlich zumindest teilweise beschichtet, beispielsweise versilbert oder vergoldet, und so dauerhaft gegen Korrosion geschützt. Weiterhin ist dadurch vorteilhafterweise auch eine dauerhaft niederohmige Steckverbindung mit anderen Kupferkontakten und darüber mit entsprechenden Kupferleitungen möglich, da der problematische Übergang zwischen Kupfer und Aluminium erfindungsgemäß in das Innere des Crimpkontaktes verlegt wird. Due to its stability and its good electrical conductivity, it is advantageous to use copper as the material for the contact area. In an advantageous embodiment, the contact region is additionally at least partially coated, for example silver-plated or gold-plated, and thus permanently protected against corrosion. Furthermore, this advantageously also a permanently low-impedance connector with other copper contacts and above with corresponding copper lines is possible, since the problematic transition between copper and aluminum according to the invention is moved into the interior of the crimp contact.
Von besonderem Vorteil ist es, dass der als Aluminium bestehende Crimpbereich mit dem aus Kupfer bestehenden Kontaktbereich durch einen Reibschweißvorgang verbunden ist, weil auf diese Weise das Entstehen einer Elektrokorrosion verhindert ist. Schließlich befindet sich die Kontaktfläche so im Inneren des Kontakts und kommt auf diese Weise nicht mit Sauerstoff in Berührung. Dadurch ist eine gute Leitfähigkeit auch nachhaltig, d.h. auch über einen langen Zeitraum, gewährleistet. It is particularly advantageous that the crimping area existing as aluminum is connected to the contact area made of copper by a friction welding process, because in this way the formation of an electrocorrosion is prevented. Finally, the contact surface is so inside the contact and does not come in this way in contact with oxygen. As a result, good conductivity is also sustainable, i. even over a long period of time, guaranteed.
Weiterhin sorgt das Verschweißen, insbesondere das Reibschweißen, für eine besonders stabile Verbindung, so dass der Crimpkontakt auch mechanisch stabil ist. Furthermore, the welding, in particular the friction welding, ensures a particularly stable connection, so that the crimp contact is also mechanically stable.
Bei der Herstellung bietet sich gemäß dem zweiten Aspekt der Erfindung die Verwendung zylinderförmiger Kupfer- und Aluminiumrohlinge an, welche in axialer Richtung aneinander, insbesondere durch Reib- schweißen, verschweißt werden. Für den Reibschweißvorgang erscheint dementsprechend zunächst das Rotationsschweißen sinnvoll. Vorteilhafterweise kann der Crimpbereich mit dem Kontaktbereich aber auch durch Vibrationsschweißen verbunden sein. In der Praxis hat sich eine Kombination aus Rotationsschweißen und Vibrationsschweißen als besonders vorteilhaft erwiesen, da beim reinen Rotationsschweißen der Nachteil besteht, dass die inneren Bereiche der Kontaktfläche eine geringere Reibung erfahren als die äußeren Bereiche, so dass die Elemente zumindest im Kontaktbereich ein zentrales sogenannte„Sackloch" aufweisen müssten. Beim etwas aufwändigeren Vibrationsschweißen erfahren dagegen sämtliche Bereiche die gleiche Reibenergie, so dass auch die inneren Bereiche der Kontaktfläche verschweißt werden können. In der Kombination können sich die Vorteile beider Verfahren sinnvoll ergänzen. In the production according to the second aspect of the invention, the use of cylindrical copper and aluminum blanks, which in the axial direction against each other, in particular by friction welded, welded. Accordingly, for the friction welding process, first of all the rotational welding makes sense. Advantageously, the crimping area may be connected to the contact area but also by vibration welding. In practice, a combination of spin welding and vibration welding has proved to be particularly advantageous, since in pure spin welding there is the disadvantage that the inner regions of the contact surface experience less friction than the outer regions, so that the elements have a central so-called "so-called" In the case of somewhat more complex vibration welding, on the other hand, all areas experience the same friction energy, so that the inner areas of the contact area can also be welded together.
Durch Drehen und Bohren kann der Kontaktbereich zum Stift- oder Buchsenkontakt ausgebildet werden und in den Crimpbereich kann der Hohlraum mit der Kabeleinführöffnung gebohrt werden. Bevorzugt kann in den Hohlraum das zusätzliche Innengewinde geschnitten werden, das der Erhöhung der auf den Litzenleiter wirkenden Reibkraft dient. By turning and drilling, the contact area can be formed for pin or socket contact, and in the crimp area, the cavity can be drilled with the cable entry opening. Preferably, the additional internal thread can be cut into the cavity, which serves to increase the frictional force acting on the stranded conductor.

Die Fig. 1 a zeigt einen Querschnitt und die Fig. 1 b zeigt eine perspektivische Darstellung eines als Stiftkontakt 1 ausgeführten ersten Crimpkon- taktes. Der Stiftkontakt 1 besitzt einen ersten Crimpbereich 1 1 und einen ersten Kontaktbereich 12, welche mit einander an einem ersten Übergangsbereich 10 in Kontakt stehen, beispielsweise indem sie, insbesondere durch einen Reibschweißvorgang, aneinander verschweißt sind. Dazu können bei der Herstellung beispielsweise zwei zylinderförmige Rohlinge, von denen einer aus Kupfer und der andere aus Aluminium besteht, in axialer Richtung aneinander angefügt und , z.B. durch Rotationsschweißen und/oder Vibrationsschweißen, aneinander verschweißt werden. Durch Drehen und Bohren kann in darauffolgenden Arbeitsschritten der aus Kupfer bestehende erste Kontaktbereich 12 einen Kontaktstift 121 erhalten, so dass es sich bei diesem Crimpkontakt um einen Stiftkontakt 1 handelt. 1 a shows a cross section and FIG. 1 b shows a perspective view of a first crimp contact designed as a pin contact 1. The pin contact 1 has a first crimping area 1 1 and a first contact area 12, which are in contact with each other at a first transition area 10, for example by being welded together, in particular by a friction welding process. For this purpose, for example, two cylindrical blanks, one of which is made of copper and the other of aluminum, joined together in the axial direction and, for example by spin welding and / or vibration welding, are welded together. By turning and drilling can be obtained in subsequent steps of the existing copper first contact portion 12 a contact pin 121 so that it is a pin contact 1 in this crimp contact.
In den aus Aluminium bestehenden ersten Crimpbereich 1 1 kann ein erster Hohlraum 1 1 1 hineingebohrt werden. Der erste Crimpbereich 1 1 besitzt dadurch an seinem freistehenden Ende angrenzend an den Hohlraum eine erste Kabeleinführöffnung 1 10. In the existing first aluminum crimp region 1 1, a first cavity 1 1 1 are drilled. The first crimping area 1 1 thereby has at its freestanding end adjacent to the cavity a first cable insertion opening 1 10th
Die Fig.2a zeigt einen Querschnitt und die Fig. 2b zeigt eine perspektivische Darstellung eines als Buchsenkontakt 2 ausgeführten zweiten FIG. 2 a shows a cross section and FIG. 2 b shows a perspective view of a second designed as a socket contact 2
Crimpkontaktes. Der Buchsenkontakt 2 besitzt einen zweiten Crimpbereich 21 und einen zweiten Kontaktbereich 22, welche mit einander an einem zweiten Übergangsbereich 20 in Kontakt stehen, beispielsweise indem sie, insbesondere durch einen Reibschweißvorgang, aneinander verschweißt sind. Dazu können bei der Herstellung beispielsweise zwei zylinderförmige Rohlinge, von denen einer aus Kupfer und der andere aus Aluminium besteht, in axialer Richtung aneinander angefügt und , z.B. durch Rotationsschweißen und/oder Vibrationsschweißen, aneinander verschweißt werden. Durch Drehen und Bohren kann in darauffolgenden Arbeitsschritten der aus Kupfer bestehende zweite Kontaktbereich 22 eine Kontaktbuchse 221 erhalten, so dass es sich bei diesem Crimpkontakt um einen Buchsenkontakt 2 handelt. Naturgemäß weist die Buchse 221 einen Buchsenhohlraum 221 1 auf, der ebenfalls bevorzugt durch Bohren entsteht. Crimp contact. The socket contact 2 has a second crimping region 21 and a second contact region 22, which are in contact with each other at a second transition region 20, for example by being welded together, in particular by a friction welding process. For this purpose, for example, two cylindrical blanks, one made of copper and the other made of aluminum, may be joined together in the axial direction and, e.g. are welded together by spin welding and / or vibration welding. By turning and drilling, the second contact region 22 consisting of copper can receive a contact socket 221 in subsequent working steps, so that this female contact 2 is in this crimp contact. Naturally, the bushing 221 has a bushing cavity 221 1, which is also preferably formed by drilling.
In den aus Aluminium bestehenden zweiten Crimpbereich 21 kann weiterhin ein Hohlraum 21 1 hineingebohrt werden. Der zweite Crimpbereich 21 besitzt dadurch an seinem freistehenden Ende angrenzend an den zweiten Hohlraum 21 1 eine zweite Kabeleinführöffnung 210. In the existing second aluminum crimp region 21, a cavity 21 1 can continue to be drilled. The second crimping region 21 has thereby at its free-standing end adjacent to the second cavity 21 1, a second cable entry opening 210th
Die Fig. 3a und 3b stellen in vergleichbarer Weise den Stiftkontakt 1 in einer modifizierten Ausführung dar, in welcher der Stiftkontakt 1 zusätzlich eine erste Durchgangsöffnung 101 besitzt, die eine zylindrische Form besitzt um darin einen hier nicht dargestellten Dorn 1 13 (dargestellt in Fig. 6a) aufnehmen zu können. Weiterhin besitzt der modifizierte Stiftkontakt 1 einen Stifthohlraum 121 1 , der über die erste zylindrische Durchgangsöffnung 101 mit dem ersten Hohlraum 1 1 1 verbunden ist. Bei der Herstellung wird die erste Durchgangsöffnung 101 bevorzugt durch Bohren erzeugt, so dass es sich bei der ersten Durchgangsöffnung 101 um eine Durchgangsbohrung handelt. Weiterhin kann in die erste Durchgangsöffnung 101 ein Innengewinde 103 geschnitten sein, so dass der Dorn 1 13, welcher ein dazu passendes Außengewinde 2132 besitzt, in die erste Durchgangsöffnung 101 und darüber in den ersten Hohlraum 1 1 1 hineingeschraubt werden kann. Figures 3a and 3b illustrate in a comparable manner the pin contact 1 in a modified embodiment, in which the pin contact 1 additionally has a first through-opening 101 which has a cylindrical shape to therein a mandrel 1 13 (shown in FIG. 6a) to be able to record. Furthermore, the modified pin contact 1 has a pin cavity 121 1, which is connected via the first cylindrical passage opening 101 with the first cavity 1 1 1. During production, the first through-opening 101 is preferably produced by drilling, so that the first through-opening 101 is a through-hole. Furthermore, an internal thread 103 can be cut into the first through-opening 101, so that the mandrel 1 13, which has a matching external thread 2132, can be screwed into the first through-opening 101 and above into the first cavity 1 1 1.
Weiterhin besitzt der erste Crimpbereich 1 1 in dieser modifizierten Ausführung in seinem ersten Hohlraum 1 1 1 ein erstes zusätzliches Innengewinde 1 12, das bei der Herstellung des Stiftkontakts 1 von innen in den ersten Crimpbereich 1 1 hineingeschnitten wird. Dieses erste zusätzliche Innengewinde 1 12 dient dazu, einen in den ersten Hohlraum 1 1 1 eingeführten Litzenleiter in diesem durch eine erhöhte Reibkraft zu halten, auch wenn der Dorn 1 13 in den ersten Hohlraum 1 1 1 in Richtung der ersten Kabeleinführöffnung 1 10, also entgegen der Einführrichtung des Litzenleiters, hineingeschraubt wird. Furthermore, the first crimping area 1 1 in this modified embodiment has in its first cavity 1 1 1, a first additional internal thread 1 12, which is cut from the inside into the first crimping area 1 1 in the manufacture of the pin contact 1. This first additional internal thread 1 12 serves to hold a introduced into the first cavity 1 1 1 stranded conductor in this by an increased frictional force, even if the mandrel 1 13 in the first cavity 1 1 1 in the direction of the first Kabeleinführöffnung 1 10, ie against the insertion direction of the stranded conductor is screwed into it.
Eine vorteilhafte Ausführung des ersten zusätzlichen Innengewindes 1 12 ist in der Fig. 3c vergrößert dargestellt. Es ist offensichtlich, dass der theoretische Innendurchmesser DT des ersten zusätzlichen Innengewindesl 12 kleiner ist als der reale Innendurchmesser DR des ersten Hohlraums 1 1 1 . Der reale Verlauf dieses Innengewindes 1 12 ist durch den schraffierten Bereich dargestellt. Dagegen gibt der nicht schraffierte Bereich den darüber hinausgehenden theoretischen Verlauf an, den ein theoretisches Innengewinde mit der theoretischen Gewindetiefe TT und dem theoretischen Gewindeinnendurchmesser DT hätte. Der reale Hohlrauminnendurchmesser DR ist jedoch größer als der theoretische Gewindeinnendurchmesser DT, der als Maßgabe für das hineinzuschneidende Innengewinde verwendet wird. Dadurch besitzt dieses Innengewinde 1 12 eine reale Gewindetiefe TR, die kleiner ist als die theoretische Gewindetiefe TT und der reale Verlauf des Gewindes 1 12 ist stärker als üblich abgeflacht. An advantageous embodiment of the first additional internal thread 1 12 is shown enlarged in Fig. 3c. It is obvious that the theoretical inner diameter D T of the first additional internal thread 12 is smaller than the real inner diameter D R of the first cavity 1 1 1. The real course of this internal thread 1 12 is represented by the hatched area. On the other hand, the non-hatched area indicates the theoretical course beyond that which a theoretical internal thread would have with the theoretical thread depth T T and the theoretical thread internal diameter D T. However, the real internal cavity diameter D R is greater than the theoretical internal thread diameter D T , which is used as a proviso for the internal thread to be cut into it. As a result, this internal thread 1 12 has a real thread depth T R , which is smaller than the theoretical thread depth T T and the real course of the thread 1 12 is flattened more than usual.
Mit anderen Worten wird bei der Herstellung nur der äußere Teil des theoretischen Innengewindes in den ersten Crimpbereich 1 1 geschnitten und das dadurch gebildete, real existierende, zusätzliche Innengewinde 1 12 besitzt somit eine besonders abgeflachte Form. In other words, during production, only the outer part of the theoretical internal thread is cut into the first crimping region 11 and the additional internal thread 12 formed as a result, thus having a particularly flattened shape.
Die Fig. 4a und 4b stellen in vergleichbarer Weise den Buchsenkontakt 2 dar, der modifiziert wurde, um einen hier noch nicht dargestellten Dorn 213 (dargestellt in Fig. 6b) aufnehmen zu können. Dazu ist der Buchsenhohlraum 221 1 über eine zweite zylindrische Durchgangsöffnung 201 mit dem zweiten Hohlraum 21 1 verbunden. Bei der Herstellung wird diese zweite Durchgangsöffnung 201 bevorzugt durch Bohren erzeugt, so dass es sich bei der zweiten Durchgangsöffnung 201 um eine Durchgangsbohrung handelt. Auch kann in die zweite Durchgangsöffnung 201 ein zweites zusätzliches Innengewinde 203 geschnitten sein, so dass der Dorn 213, der ein dazu passendes Außengewinde 2132 besitzt, in die zweite Durchgangsöffnung 201 und darüber in den zweiten Hohlraum 21 1 hineingeschraubt werden kann. FIGS. 4a and 4b represent, in a comparable manner, the socket contact 2, which has been modified in order to be able to receive a pin 213 (shown in FIG. 6b) not shown here. For this purpose, the socket cavity 221 1 is connected via a second cylindrical passage opening 201 to the second cavity 21 1. During production, this second through-opening 201 is preferably produced by drilling, so that the second through-opening 201 is a through-hole. Also, in the second through hole 201, a second additional internal thread 203 may be cut, so that the mandrel 213, which has a mating external thread 2132, can be screwed into the second through hole 201 and above in the second cavity 21 1.
Weiterhin besitzt der zweite Crimpbereich 21 im zweiten Hohlraum 21 1 ein zweites zusätzliches Innengewinde 212, das bei der Herstellung von innen in den Crimpbereich 21 des Buchsenkontaktes 2 hineingeschnitten wird. Dieses zweite zusätzliche Innengewinde 212 dient dazu, einen in den zweiten Hohlraum 21 1 eingeführten Litzenleiter in diesem durch eine erhöhte Reibkraft zu halten, auch wenn der Dorn 213 in den zweiten Hohlraum 21 1 in Richtung der zweiten Kabeleinführöffnung 210, also entgegen der Einführrichtung des Litzenleiters, hineingeschraubt wird. Furthermore, the second crimping region 21 in the second cavity 21 1 has a second additional internal thread 212, which is cut into the crimping region 21 of the socket contact 2 during manufacture from the inside. This second additional internal thread 212 serves to retain a stranded conductor introduced into the second cavity 21 1 in this by an increased frictional force, even if the mandrel 213 in the second cavity 21 1 in the direction of the second Kabeleinführöffnung 210, ie opposite to the insertion of the stranded conductor , is screwed into it.
Eine vorteilhafte Ausführung des zweiten zusätzlichen Innengewindes 212 ist in der Fig. 4c vergrößert dargestellt. Der reale Verlauf dieses Innengewindes 212 ist durch den schraffierten Bereich dargestellt. Dagegen gibt der nicht schraffierte Bereich den weiteren theoretischen Verlauf an, den ein theoretisches Innengewinde mit der theoretischen Gewindetiefe TT und dem theoretischen Gewindeinnendurchmesser DT hätte. Der Hohlrauminnendurchmesser DR ist demnach größer als der theoretische Gewindeinnendurchmesser DT, der jedoch als Maßgabe für das hineinzuschneidende Innengewinde verwendet wird. Dadurch besitzt dieses Innengewinde 212 eine reale Gewindetiefe TR, die kleiner ist als die theoretische Gewindetiefe TT und der reale Verlauf des Gewindes 212 ist stärker als üblich abgeflacht. An advantageous embodiment of the second additional internal thread 212 is shown enlarged in FIG. 4c. The real history of this internal thread 212 is represented by the hatched area. In contrast, the non-hatched area indicates the further theoretical course that a theoretical internal thread would have with the theoretical thread depth T T and the theoretical thread internal diameter D T. The cavity internal diameter D R is therefore greater than the theoretical internal thread diameter D T , which is however used as a proviso for the inner thread to be cut into it. As a result, this internal thread 212 has a real thread depth T R , which is smaller than the theoretical thread depth T T and the real course of the thread 212 is flattened more than usual.
Mit anderen Worten wird bei der Herstellung nur der äußere Teil des theoretischen Innengewindes in den zweiten Crimpbereich 21 geschnitten und das dadurch gebildete, real existierende, zusätzliche Innengewinde 212 besitzt somit eine besonders abgeflachte Form. In other words, during production, only the outer part of the theoretical internal thread is cut into the second crimping region 21, and the additional existing internal thread 212 formed as a result thus has a particularly flattened shape.
In den Fig. 5a und 5b sind der Stiftkontakt 1 und der Buchsenkontakt 2 mit der jeweiligen zylindrischen Durchgangsöffnung 101 , 201 in einer geschnittenen 3D-Darstellung einander gegenüber gestellt. In FIGS. 5a and 5b, the pin contact 1 and the socket contact 2 with the respective cylindrical through-opening 101, 201 are compared with one another in a sectional 3D representation.

Jede der Durchgangsöffnungen 101 , 201 besitzt ein dazu gehöriges Innengewinde 103, 203. Der jeweilige Dorn 1 13, 213 besitzt jeweils ein dazu passendes Außengewinde 1 132, 2132, mit dem er in die jeweilige Durchgangsöffnung 101 , 201 eingeschraubt ist. Weiterhin kann der Dorn 1 13, 213 einen Schraubkopf 1 131 , 2131 besitzen, der das Einschrauben aus dem Stift- oder Buchsenhohlraum 121 1 , 221 1 heraus ermöglicht. 6a and 6b show the pin contact 1 and the socket contact 2 with the respective through hole 101, 201 and a corresponding first and second mandrel 1 13, 213. Each of the through holes 101, 201 has an associated internal thread 103, 203rd Der respective Mandrel 1 13, 213 each has a matching external thread 1 132, 2132, with which it is screwed into the respective passage opening 101, 201. Furthermore, the mandrel 1 13, 213 have a screw head 1 131, 2131, which allows screwing out of the pin or socket cavity 121 1, 221 1 out.
Die Fig.7 zeigt einen kompletten Schwerlaststeckverbinder in einer Explosionsdarstellung. Exemplarisch wird ein Stiftkontakt 1 dargestellt. Ebenso gut könnte es sich aber auch um einen Buchsenkontakt 2 handeln. FIG. 7 shows a complete heavy duty connector in an exploded view. By way of example, a pin contact 1 is shown. But it could just as well be a socket contact 2.
Weiterhin ist ein Isolierkörper 3 dargestellt, der dazu vorgesehen ist, den Stiftkontakt 1 aufzunehmen. Dieser Isolierköper 3 kann seinerseits über Befestigungselemente 31 in dem Steckverbindergehäuse 4 befestigt werden. Furthermore, an insulating body 3 is shown, which is intended to receive the pin contact 1. This Isolierköper 3 can in turn be fastened via fasteners 31 in the connector housing 4.
