Die vorliegende Erfindung betrifft weiterhin eine Stromschiene für eine solche Anordnung sowie ein Verfahren zum elektrischen Verbinden von mindestens zwei solchen Stromschienen.The present invention relates to an arrangement of a first busbar and a second busbar for electrically connecting electrical conductors and / or assemblies, wherein the busbars each have at least one surface which are spanned in a longitudinal direction and an extension direction. The present invention further relates to a busbar for such an arrangement and to a method for electrically connecting at least two such busbars.
Stromschienen werden zum Verbinden von elektrischen Leitern und/oder Baugruppen genutzt. An den Verbindungsstellen der Stromschienen untereinander sowie zu den Leitern und/oder Baugruppen muss der elektrische Kontakt dauerhaft zuverlässig sichergestellt sein. In Abhängigkeit vom Anwendungsgebiet, beispielsweise in der Fertigungsindustrie, soll das Verbinden zudem einfach und schnell durchführbar sein, um ein schnelles Umrüsten der Baugruppen und Anlagen zu ermöglichen.Busbars are used to connect electrical conductors and / or assemblies. At the junctions of the busbars with each other and to the conductors and / or assemblies of the electrical contact must be permanently ensured reliable. Depending on the field of application, for example in the manufacturing industry, the connection should moreover be simple and quick to carry out, in order to enable rapid conversion of the assemblies and installations.
Untereinander werden Stromschienen dafür regelmäßig verschraubt, verschweißt oder vernietet. Dabei muss auf die verwendeten Materialien, insbesondere der Schrauben und/oder Hülsen, geachtet werden, damit die Kontaktierung bei gegebenenfalls unterschiedlichen Materialen trotz verschiedenen Temperatur- und Korrosionsverhaltens langfristig gewährleistet ist. Die Kontaktierung zu elektrischen Leitern wird oftmals mittels einer Quetschverbindung hergestellt. Verschrauben, verschweißen oder vernieten sind relativ teure Verbindungstechniken.Bus bars are regularly bolted, welded or riveted to one another. Care must be taken to the materials used, in particular the screws and / or sleeves, so that the contact is guaranteed in the long term, if different materials despite different temperature and corrosion behavior. The contact with electrical conductors is often produced by means of a crimp connection. Screwing, welding or riveting are relatively expensive joining techniques.
Bekannt ist es auch, die Stromschienen untereinander sowie Leiter und/oder Baugruppen mittels Federn zu verbinden. Die Druckschrift
Die Nutzung von Federn ist gegenüber einer Verschraubung schneller montierbar sowie lösbar, kann sich jedoch bei einer insbesondere erheblichen Vibrationsbelastung gegebenenfalls auf Dauer selbsttätig lösen. Dabei ist die Lösbarkeit der Verbindung je nach Anwendungsbereich nicht immer erforderlich.The use of springs is compared to a screw faster mountable and solvable, but may eventually solve automatically in a particularly significant vibration load permanently. The solubility of the compound depending on the application is not always required.

Es ist aber ebenfalls bevorzugt, dass Stromschienen miteinander kombiniert werden, die einen verschiedenen Querschnitt aufweisen, und/oder deren Anzahl Kontaktlaschen und/oder Kontaktaufnahmen unterschiedlich sind. Besonders bevorzugt weist die erste Stromschiene nur eine oder mehrere Kontaktaufnahmen auf, wobei die zweite Stromschiene nur eine oder mehrere Kontaktlaschen aufweist. weiterhin bevorzugt sind die Stromschienen jeweils flächig, linienförmig oder im Querschnitt L-, S- oder U- förmig ausgebildet. Bei im Querschnitt L-, S oder U- förmiger Ausbildung weisen die Stromschienen zumindest zwei Flächen auf, die zum Anordnen zumindest einer Kontaktlasche und/oder zumindest einer Kontaktaufnahme nutzbar sind. Dabei können die flächig, linienförmig, L-, S- oder U- förmig ausgebildeten Stromschienen beliebig miteinander kombiniert werden.For the busbars are constructed identical in a first preferred embodiment. However, it is also preferred that bus bars are combined with each other, which have a different cross-section, and / or their number of contact tabs and / or contact receptacles are different. Particularly preferably, the first bus bar on only one or more contact receptacles, wherein the second bus bar has only one or more contact tabs. Furthermore, the busbars are each preferably flat, linear or L-shaped, S-shaped or U-shaped in cross-section. In cross-section L, S or U-shaped design, the busbars on at least two surfaces, which are available for arranging at least one contact tab and / or at least one contact. In this case, the flat, linear, L, S or U-shaped busbars can be combined with each other as desired.
Vorzugsweise ist eine Breite der Kontaktlasche zumindest punktuell oder bereichsweise nahezu gleich oder nur unwesentlich kleiner als eine Breite der Kontaktaufnahme. Dadurch passt die Kontaktlasche in diesem Bereich nahezu passgenau in die Kontaktaufnahme. Beim Verprägen wird der mechanische Formschluss sowie elektrische Kontakt zumindest in diesem Bereich hergestellt. Dadurch können, insbesondere zwei einander gegenüberliegende, Kontaktpunkte oder Kontaktbereiche gezielt definiert werden. Der Stromweg wird dann von der einen Stromschiene durch definierte Kontaktpunkte oder -Bereiche in die zweite Stromschiene geleitet.Preferably, a width of the contact tab is at least selectively or partially almost equal to or only slightly smaller than a width of the contact. As a result, the contact tab in this area fits almost exactly in the contact. When stamping the mechanical positive connection and electrical contact is made at least in this area. As a result, in particular two opposing contact points or contact areas can be specifically defined. The current path is then passed from the one bus bar through defined contact points or areas in the second bus bar.
Um die Montage der Stromschienen miteinander zu vereinfachen, ist es bevorzugt, dass die Kontaktlasche und/oder die Kontaktaufnahme der Stromschienen jeweils einen Kontakthals aufweisen, an dem ein Kontaktkopf angeordnet ist. Bei einem Einschieben, Einlegen oder Einrasten der Kontaktlasche in eine Fügerichtung in die Kontaktaufnahme rastet die Kontaktlasche aufgrund der sich am Kontakthals verjüngenden Kontur in die Kontaktaufnahme ein. Sie wird dann ohne bereits verprägt zu sein verliersicher gehalten und kann sich nicht selbsttätig gegen die Fügerichtung aus der Kontaktaufnahme lösen.In order to simplify the mounting of the busbars with one another, it is preferred that the contact tab and / or the contact receptacle of the busbars each have a contact neck on which a contact head is arranged. When inserting, inserting or locking the contact tab in a joining direction in the contact, the contact tab snaps due to the tapering at the contact neck Contour into the contact. It is then without being embossed to be held captive and can not solve automatically against the joining direction from the contact.
Dabei ist es besonderes bevorzugt, dass jeweils der Kontaktkopf der Kontaktaufnahme der Stromschienen in der Fügerichtung länger als der Kontaktkopf der Kontaktlasche der Stromschienen ausgebildet ist. Dadurch kann die Kontaktlasche in und gegen die Fügerichtung verschoben werden, bevor die Stromschienen miteinander verprägt werden. Dies ermöglicht bei der Montage der Stromschienen miteinander einen Toleranzausgleich in Fügerichtung.It is particularly preferred that in each case the contact head of the contact of the busbars in the joining direction is formed longer than the contact head of the contact tab of the busbars. As a result, the contact tab can be moved in and against the joining direction before the busbars are stamped together. This allows for the mounting of the busbars with each other a tolerance compensation in the joining direction.
In einer besonders bevorzugten Ausführungsform umfassen die Stromschienen jeweils zwei Flächen, an denen jeweils zumindest eine Kontaktlasche, vorzugsweise zwei Kontaktlaschen, und/oder in denen zumindest eine Kontaktaufnahme, vorzugsweise zwei Kontaktaufnahmen, angeordnet sind. Dabei ist es weiterhin bevorzugt, dass die zumindest eine Kontaktlasche und/oder die zumindest eine Kontaktaufnahme der einen der beiden Flächen in Längsrichtung gegenüber der zumindest einen Kontaktlasche und/oder der zumindest einen Kontaktaufnahme der anderen der beiden Flächen versetzt angeordnet ist. Dadurch ist eine Verschachtelung mehrerer Stromschienen möglich.In a particularly preferred embodiment, the busbars each comprise two surfaces, on each of which at least one contact tab, preferably two contact tabs, and / or in which at least one contact, preferably two contact receptacles, are arranged. It is further preferred that the at least one contact tab and / or the at least one contact receiving one of the two surfaces in the longitudinal direction relative to the at least one contact tab and / or the at least one contact receiving the other of the two surfaces is arranged offset. As a result, nesting of multiple busbars is possible.
Dabei ist eine U- förmige Ausbildung der Stromschienen ganz besonders bevorzugt. Zwei U- förmige Stromschienen sind dann übereinander anordbar. Ein von den Stromschienen jeweils umgebener Innenraum wird dabei bevorzugt zum elektrisch kontaktierenden Befestigen von elektrischen Leitern genutzt.In this case, a U-shaped design of the busbars is particularly preferred. Two U-shaped busbars can then be arranged one above the other. One of the busbars each surrounded interior is preferably used for electrically contacting attaching electrical conductors.
Die Aufgabe wird weiterhin gelöst mit einer Stromschiene für eine solche Anordnung. Die Stromschiene weist zumindest eine Fläche auf, die in eine Längsrichtung und eine Erstreckungsrichtung aufgespannt ist. Weiterhin weist sie zumindest eine sich von einem Rand der Fläche aus erstreckende Kontaktlasche und/oder zumindest eine in der Fläche angeordnete Kontaktaufnahme auf. Die Kontaktlasche und/oder die Kontaktaufnahme der Stromschiene sind zum Verprägen mit einer Kontaktaufnahme und/oder einer Kontaktlasche einer anderen korrespondierenden Stromschiene vorgesehen.The object is further achieved with a busbar for such an arrangement. The bus bar has at least one surface which is spanned in a longitudinal direction and an extension direction. Furthermore, it has at least one contact lug extending from one edge of the surface and / or at least one contact arranged in the surface. The contact tab and / or the contact of the busbar are provided for embossing with a contact and / or a contact tab of another corresponding busbar.
Die Aufgabe wird weiterhin gelöst mit einem Verfahren zum elektrischen Verbinden von mindestens zwei solchen Stromschienen miteinander, bei dem
- die Stromschienen zueinander geschoben werden, bis die zumindest eine Kontaktlasche der einen Stromschiene in der zumindest eine Kontaktaufnahme der anderen Stromschiene angeordnet ist, vorzugsweise eingerastet ist, und
- die Kontaktlasche dann mit einem Prägewerkzeug mit der Kontaktaufnahme verprägt wird,
- the busbars are pushed towards each other until the at least one contact tab of the one busbar is arranged in the at least one contact receiving the other busbar, is preferably engaged, and
- the contact tab is then embossed with a stamping tool with the contact,
Das Prägen kann vorteilhaft und einfach mit einem Prägestempel erfolgen, der senkrecht zur Fläche der Kontaktlasche auf die Kontaktlasche zugestellt wird und sie radial aufweitet, so dass sie sich radial innen an den Innenumfang der Kontaktaufnahme anlegt, die entsprechend niedergehalten werden kann.The embossing can be carried out advantageously and simply with an embossing die which is delivered perpendicular to the surface of the contact tab on the contact tab and radially expands so that it applies radially inward to the inner periphery of the contact, which can be held down accordingly.

Beide Stromschienen 1, 1' weisen zwei Flächen 12, 13, 12', 13' auf, hier auch Schenkelflächen genannt, die sich jeweils in die Längsrichtung 31 und eine Fügerichtung 32 erstrecken. Die Schenkelflächen 12, 13, 12', 13' der Stromschienen 1, 1' sind jeweils durch eine Verbindungsfläche 11, 11' miteinander verbunden, die sich in die Längsrichtung 31 und eine Querrichtung 33 erstreckt. Die Stromschienen 1, 1' sind einstückig als Stanzbiegebauteil aus einem Blech gebildet. Dabei sind die Schenkelflächen 12, 12', 13, 13' durch Biegen des Bleches um etwa einen rechten Winkel (nicht gezeigt) gegenüber der Verbindungsfläche 11, 11' gebildet. Daher sind die Schenkelflächen 12, 13, 12', 13' jeweils an einer Biegekante 171, 172, 171', 172', die sich in Längsrichtung 31 erstreckt, mit der Verbindungsfläche 11, 11' verbunden.Both
In den Schenkelflächen 12, 13 der ersten Stromschiene 1 sind jeweils zwei Ausnehmungen angeordnet, die als Kontaktaufnahmen 14 vorgesehen sind und zur Aufnahme von Kontaktlaschen 15' der zweiten Stromschiene 1' dienen. Dafür ist eine Kontur der Kontaktlaschen 15' der zweiten Stromschiene 1' korrespondierend zu einer Kontur der Kontaktaufnahmen 14 der ersten Stromschiene 1 ausgebildet, so dass die Kontaktlaschen 15' jeweils in die Kontaktaufnahmen 14 passen.In the leg surfaces 12, 13 of the
Die Kontaktaufnahmen 14 erstrecken sich jeweils von der Biegekante 171, 172 aus in die Schenkelfläche 12, 13 der ersten Stromschiene 1 hinein. Die Kontaktaufnahmen 14 der gegenüberliegenden Schenkelflächen 12, 13 weisen jeweils den gleichen Abstand A1, A2 zueinander auf. Jedoch sind die Kontaktaufnahmen 14 der einen der beiden Schenkelflächen 12, 13 in Längsrichtung 31 gegenüber den Kontaktaufnahmen 14 der anderen der beiden Flächen 12, 13 um einen Versatz ΔA zueinander versetzt angeordnet.The contact receptacles 14 each extend from the bending
An einem Rand 161', 162' der Schenkelflächen 12', 13' der zweiten Stromschiene 1' sind in analoger Weise jeweils zwei Kontaktlaschen 15' angeordnet. Auch die Kontaktlaschen 15' weisen an den Schenkelflächen 12', 13' jeweils den gleichen Abstand A1', A2' zueinander auf. Jedoch sind auch die Kontaktlaschen 15' der einen der beiden Schenkelflächen 12', 13' in Längsrichtung 31 gegenüber den Kontaktlaschen 15' der anderen der beiden Flächen 12', 13' um einen Versatz ΔA' zueinander versetzt angeordnet.At an
Der Versatz ΔA, ΔA' ist hier bei beiden Stromschienen 1, 1' gleich. Dadurch sind die Stromschienen 1, 1' übereinander anordbar. Zudem sind sie so auch miteinander verschachtelbar, so dass sie schräg untereinander angeordnet sind. Beim verschachtelten Anordnen können auch noch weitere Stromschienen (nicht gezeigt) mit diesen beiden Stromschienen 1, 1' verbunden werden. Dabei werden jeweils nur die Kontaktlaschen 15' einer der beiden Schenkelflächen 12', 13' der zweiten Stromschiene 1' mit den Kontaktaufnahmen 14 einer der beiden Schenkelflächen 13, 12 der ersten Stromschiene 1 miteinander verbunden.The offset .DELTA.A, .DELTA.A 'is the same here for both
Sichtbar ist, dass eine Länge L der beiden Stromschienen 1, 1' sowie eine Breite B der beiden Stromschienen 1, 1' hier gleich sind. Prinzipiell können auch verschieden breite und/oder verschieden lange Stromschienen 1, 1' miteinander verbunden werden, solange der Abstand A1, A2, A1', A2' der Kontaktlaschen 15' und der Kontaktaufnahmen 14 zueinander passend ausgebildet ist, und die Konturen der Kontaktlaschen 15' und der Kontaktaufnahmen 14 zueinander korrespondieren.It can be seen that a length L of the two
Bei dieser Ausführungsform der Stromschienen 1, 1' weisen sowohl die Kontaktlaschen 15' als auch die Kontaktaufnahmen 14 jeweils einen Kontaktkopf 152', 142 und einen Kontakthals 151', 141 auf. Der Kontakthals 151', 141 ist gegenüber dem Kontaktkopf 152', 142 jeweils schmaler ausgebildet. Dabei weist die Kontaktlasche 15' insgesamt eine kleinere Kontur auf als die Kontaktaufnahme 14, so dass sie in die Kontaktaufnahme 14 einlegbar oder einrastbar ist. Nach dem Einlegen oder Einrasten der Kontaktlasche 15' in die Kontaktaufnahme 14 kann die Kontaktlasche 15' aufgrund der Verjüngung der Kontaktaufnahme 14 an ihrem Kontakthals 141 nicht mehr gegen die Fügerichtung 30 aus der Kontaktaufnahme 14 rutschen. Die zweite Stromschiene 1' ist dann bereits auch ohne ein Verprägen verliersicher an der ersten Stromschiene 1 befestigt.In this embodiment of the
Im zweiten Ausschnitt (II) sind die erste der beiden Kontaktlaschen 15' und ihre Kontaktaufnahme 14 beim Verprägen mit einem Prägewerkzeug 2 dargestellt. Beim Verprägen wird im Innenraum 100 (hier nicht sichtbar) ein Konterwerkzeug (nicht gezeigt) angeordnet, dass die Kontaktlasche 15' in der Kontaktaufnahme 14 hält. Das Prägewerkzeug 2 wird dann mit Druck, beispielsweise mit einem Hammer (nicht gezeigt), auf die Kontaktlasche 15' gedrückt. Dabei verformt sich die Kontaktlasche 15' und wird gegen die Kontaktaufnahme 14 gedrückt. Dadurch wird sie formschlüssig und vorzugsweise auch kraftschlüssig und dazu gut elektrisch leitend mit der Kontaktaufnahme 14 verbunden.In the second section (II), the first of the two contact tabs 15 'and their
Der dritte Ausschnitt (III) zeigt die zweite der beiden Kontaktlaschen 15' der Schenkelfläche 13' der zweiten Stromschiene 1' in der Kontaktaufnahme 14 der ersten Stromschiene 1 vergrößert. Diese Kontaktlasche 15' und Kontaktaufnahme14 sind bereits miteinander verprägt. Der dritte Ausschnitt (III) zeigt daher den Verbindungszustand V.The third section (III) shows the second of the two contact lugs 15 'of the leg surface 13' of the second busbar 1 'in the
Eine Breite b5' des Kontaktkopfes 152' der Kontaktlasche 15' in seiner Mitte M5' ist hingegen nur unwesentlich geringer als eine Breite b4 des Kontaktkopfes 142 der Kontaktaufnahme 14, so dass beim Verprägen in diesem Bereich ein mechanischer Formschluss, und somit ein elektrischer Verbindungspunkt, definiert herstellbar ist.A width b5 'of the contact head 152' of the contact tab 15 'in its center M5', however, is only slightly smaller than a width b4 of the

Beim Fügen der beiden Stromschienen 1, 1' aneinander werden hier jeweils zwei Kontaktlaschen 15, 15' eines Randes 162, 161' der Stromschienen 1, 1' in zwei Kontaktaufnahme 14', 14 eines Randes 161', 162 der anderen Stromschiene 1, 1' eingelegt und dann miteinander verprägt. Dadurch kann mit diesen Stromschienen 1, 1' beispielsweise eine Potentialfläche gebildet werden, die als Abschirmung dienen kann.When joining the two

Dabei sind an den gegenüberliegenden Rändern 161, 162 der ersten Stromschiene 1 jeweils zwei Kontaktlaschen 15 angeordnet, während an den gegenüberliegenden Rändern 161', 162' der zweiten Stromschiene 1' jeweils zwei Kontaktaufnahmen 14' angeordnet sind. Um ein Verschachteln mehrerer Stromschienen (nicht gezeigt) zu ermöglichen, sind die an den gegenüber liegenden Rändern 161, 162, 161', 162' derselben Stromschiene 1, 1' angeordneten Kontaktlaschen 15 beziehungsweise Kontaktaufnahmen 14' zueinander versetzt.In each case, two contact lugs 15 are arranged at the
Auch mit dieser Ausführungsform der Stromschienen 1, 1' kann eine abschirmende Potentialfläche gebildet werden. Die Anordnung ist jedoch auch zum elektrisch leitenden Verbinden mit elektrischen Leitern nutzbar.Even with this embodiment of the
