Description

Die vorliegende Erfindung betrifft ein elektrisches Anschlusselement gemäß dem Oberbegriff des Anspruchs 1, wie es beispielsweise aus der US 3,259,869 , der JP 58 081870 U oder der JP 61 019979 U bekannt geworden ist.The present invention relates to an electrical connection element according to the preamble of claim 1, as it is known for example from US 3,259,869 , of the JP 58 081870 U or the JP 61 019979 U has become known.

Um mit den in der EP 2 065 982 A1 beschriebenen Anschlusselementen eine elektrische Verbindung herstellen zu können, werden zwei identische Anschlusselemente mit ihren einander zugewandten Vorderseiten beabstandet zueinander angeordnet, wobei die beiden Anschlusselemente jeweils etwa 45° in eine erste, entgegen den frei auskragenden Enden der Verriegelungsflügel zeigende Richtung relativ zueinander verdreht und derart miteinander in Anlage gebracht werden, dass die Hintergreifungsabschnitte des einen elektrischen Anschlusselements mit den Speichen des anderen Anschlusselements in Anlage gelangen. Anschließend werden die beiden Anschlusselemente in einer der ersten Drehrichtung entgegengesetzten zweiten Richtung derart relativ zueinander verdreht, dass die frei auskragenden Enden der Hintergreifungsabschnitte eines jeden elektrischen Anschlusselements in den lichten Abstand eintaucht, den jeder der Hintergreifungsabschnitte des jeweils anderen Anschlusselements zu dem Zentralabschnitt, dem Ringabschnitt sowie den Speichen aufweist. Bei weiter anhaltender Drehbewegung reiten schließlich die frei auskragenden Enden der Hintergreifungsabschnitte auf den Rampenabschnitten des jeweils anderen Anschlusselements auf, was bei anhaltender Drehbewegung dazu führt, dass sich die elektrischen Anschlusselemente und insbesondere deren Ring- und Zentralabschnitte in axialer Richtung aufeinander zu bewegen, wodurch die Anschlusselements gegeneinander verspannt werden. Um also eine elektrische Verbindung unter Verwendung zweier Anschlusselemente herstellen zu können, wie sie in der EP 2 065 982 A1 beschrieben werden, müssen die Anschlusselemente einer kombinierten Steck-Dreh-Bewegung unterworfen werden, wobei die beiden Anschlusselemente bei anhaltender Drehbewegung in axialer Richtung aufeinander zu bewegt und gegeneinander verspannt werden.To deal with those in the EP 2 065 982 A1 described two connecting elements with their facing front sides spaced from each other, wherein the two connection elements each about 45 ° in a first, against the cantilevered ends of the locking wings pointing direction relative to each other and twisted together in such a way Be brought system that the Hintergreifungsabschnitte of one electrical connection element with the spokes of the other connection element come into abutment. Subsequently, the two connection elements are rotated relative to each other in a second direction opposite to the first direction of rotation, that the freely projecting ends of the Hintergreifungsabschnitte of each electrical connection element immersed in the clearance, each of the Hintergreifungsabschnitte the other connection element to the central portion, the ring portion and has the spokes. With continuing rotation, finally, the freely projecting ends of the Hintergreifungsabschnitte ride on the ramp sections of the other connection element, which leads to sustained rotational movement that the electrical connection elements and in particular their ring and central sections in the axial direction to each other to move, whereby the connection element are braced against each other. So to be able to produce an electrical connection using two connection elements, as shown in the EP 2 065 982 A1 be described, the connection elements of a combined plug-and-turn movement must be subjected, wherein the two connection elements are moved toward each other in the axial direction with continued rotational movement and braced against each other.

Da das in der EP 2 065 982 A1 beschriebene Anschlusselement einer Drehbewegung unterworfen werden muss, um eine elektrische Verbindung herzustellen, eignet sich dieses Anschlusselement nicht zur Herstellung einer reinen Steckverbindung.Since that in the EP 2 065 982 A1 described connection element must be subjected to a rotational movement to produce an electrical connection, this connection element is not suitable for the production of a pure connector.

Ferner kommt hinzu, dass zwei miteinander zu koppelnde elektrische Komponenten nur über jeweils ein Paar von Anschlusselementen, wie sie in der EP 2 065 982 A1 beschrieben werden, gekoppelt werden können, was auf die erforderliche Drehbewegung zurückzuführen ist, der die Anschlusselemente zur Herstellung einer elektrischen Verbindung unterworfen werden müssen. Falls über ein derartiges Anschlusselement somit stärkere Ströme übertragen werden sollen, als ein einzelnes Anschlusselement zu übertragen in der Lage ist, ist es nicht möglich, einfach mehrere gleiche Anschlusselemente nebeneinander an einem elektrischen Bauteil vorzusehen, da sich die erforderliche Drehbewegung stets nur in Bezug auf eines der Anschlusselemente erzeugen lässt. Mit anderen Worten lässt sich das Anschlusselement der EP 2 065 982 A1 nicht mehrfach nebeneinander an einem elektrischen Bauteil vorsehen, um so auch sehr große Ströme übertragen zu können.In addition, two electrical components to be coupled to one another can only be connected via a respective pair of connecting elements, as shown in FIG EP 2 065 982 A1 can be coupled, which is due to the required rotational movement, which must be subjected to the connection elements for making an electrical connection. If, therefore, stronger currents are to be transmitted via such a connection element than a single connection element is capable of transmitting, it is not possible simply to provide a plurality of identical connection elements next to one another on an electrical component, since the required rotary movement always occurs only in relation to one can produce the connection elements. In other words, the connection element of EP 2 065 982 A1 do not provide multiple side by side on an electrical component, so as to be able to transmit very large currents.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Anschlusselement derart weiterzuentwickeln, dass es zur Übertragung möglichst großer Stromstärken geeignet ist.The invention has for its object to further develop a generic connection element such that it is suitable for transmitting the largest possible currents.

Diese Aufgabe wird erfindungsgemäß durch ein elektrisches Anschlusselement mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by an electrical connection element with the features of claim 1.

Um die Klemmkraft zwischen zwei miteinander gekoppelten Anschlusselementen gezielt beeinflussen zu können und um definierte Strompfade zwischen den beiden Anschlusselementen vorzusehen, weist jeder Finger des erfindungsgemäßen Anschlusselements zwei lokal begrenzte Kontaktauswölbung auf, welche sich auf der ersten Seite des Blechs erstrecken, aus dem das erfindungsgemäße Anschlusselement gefertigt ist. Durch die in Rede stehenden Kontaktauswölbungen werden somit definierte Kontaktstellen geschaffen, an denen zwei miteinander zu verbindende elektrische Anschlusselemente in Kontakt gelangen. Durch gezielte Anordnung der Kontaktauswölbungen an den Fingern lässt sich dabei die Verteilung des Stromflusses und der Erwärmung über die Anschlusselemente in der gewünschten Weise beeinflussen, wodurch die Stromfestigkeit der Anschlusselemente erhöht werden kann. Die Kontaktauswölbungen sind dabei derart über das Anschlusselement und insbesondere über die Finger desselben verteilt, dass die einzelnen Kontaktauswölbungen im mit einem identischen Anschlusselement verbundenen Zustand annähernd gleich große Klemmkräfte erfahren.In order to be able to influence the clamping force between two connection elements coupled to one another in a targeted manner and to provide defined current paths between the two connection elements, each finger of the connection element according to the invention has two locally limited contact convexities which extend on the first side of the sheet from which the connection element according to the invention is made is. Defined contact points are thus created by the contact bulges in question, at which two electrical connection elements to be connected to one another come into contact. Through targeted arrangement of the contact bulges on the fingers, the distribution of the current flow and the heating via the connection elements can be influenced in the desired manner, whereby the current resistance of the connection elements can be increased. The contact bulges are distributed over the connecting element and in particular over the fingers of the same, that experience the individual contact bulges in the connected state with an identical connection element approximately equally large clamping forces.

Die Kontaktauswölbungen sind dabei vorzugsweise derart verteilt über die jeweiligen Finger angeordnet, dass die Kontaktauswölbungen der beiden Anschlusselemente im miteinander verbundenen Zustand zweier identischer Anschlusselemente aufeinander zu liegen kommen und in Kontakt miteinander stehen. Da sich die Kontaktauswölbungen von der erstenThe contact bulges are preferably distributed over the respective fingers so arranged that the contact bulges of the two connecting elements in the interconnected state of two identical connection elements come to rest on each other and are in contact. Since the contact bulges of the first

Seite des Blechs aus in die Höhe erstrecken, reiten einander zugeordnete Kontaktauswölbungen zweier miteinander zu verbindender Anschlusselemente während des Zusammensteckens aufeinander auf, wodurch die Finger elastisch verformt und somit vorgespannt werden. Durch die so erzielte Vorspannung wird ein gezielter Reibschluss zwischen zwei miteinander zu verbindenden elektrischen Anschlusselemente geschaffen.Side of the sheet extend into the height, ride each other associated contact bulges of two connecting elements to be connected together during the mating on each other, whereby the fingers are elastically deformed and thus biased. As a result of the pretensioning thus achieved, a targeted frictional engagement is created between two electrical connection elements to be connected to one another.

Die zwei in Steckrichtung des Anschlusselements frei auskragenden Finger definieren zwischen ihnen einen am vorderen Ende des Anschlusselements offenen Spalt, welcher durch die aus der Blechebene herausgebogene, frei auskragende Zunge überdeckt ist. Beim Zusammenstecken zweier miteinander zu verbindender (identischer) Anschlusselemente dienen die Finger eines Anschlusselements bzw. der durch diese gebildete Spalt als Führung für die Zunge des jeweils anderen Anschlusselements, wodurch ein passgenauer Sitz zweier miteinander zu verbindender (identischer) Anschlusselemente sichergestellt werden kann.The two freely projecting in the insertion direction of the connecting element fingers define between them a gap open at the front end of the connecting element, which is covered by the bent out of the sheet plane, cantilevered tongue. When mating two (identical) connection elements to be connected to one another, the fingers of one connection element or the gap formed thereby serve as guides for the tongue of the respective other connection element, whereby a snug fit of two (identical) connection elements to be connected can be ensured.

Dadurch, dass sich die beiden frei auskragenden Finger wie die frei auskragende Zunge in Steckrichtung des Anschlusselements erstrecken und dabei das vordere Ende desselben bilden, können zwei um 180° zueinander verdrehte identische Anschlusselemente mit den freien Enden der frei auskragenden Finger voraus durch eine lineare Steckbewegung miteinander in Eingriff gebracht werden, was zur Folge hat, dass das Metallblech, aus dem das jeweilige Anschlusselement gestanzt ist, zwischen den beiden Fingern und der frei auskragenden Zunge des jeweils anderen Anschlusselements reibschlüssig festgeklemmt wird.Characterized in that the two cantilevered fingers such as the cantilevered tongue extend in the insertion direction of the connecting element while the same form the front end, two 180 ° to each other twisted identical connection elements with the free ends of the cantilevered fingers ahead by a linear insertion movement with each other be brought into engagement, which has the consequence that the metal sheet from which the respective connection element is punched, between the two fingers and the cantilevered tongue of the other connection element is frictionally clamped.

Die beiden Anschlusselemente lassen sich somit in der gewünschten Weise durch eine lineare Steckbewegung miteinander koppeln, wobei sie dann über Reibschluss aneinander gesichert sind. Bei diesem Steckvorgang dienen die beiden frei auskragenden Finger eines jeden Anschlusselements gewissermaßen als Führung für das jeweils andere Anschlusselement, da während des Steckvorgangs die frei auskragende Zunge mit ihrem freien Ende voraus in den Schlitz zwischen den beiden frei auskragenden Fingern des anderen Anschlusselements eintaucht, welche durch das Herausbiegen der Zunge des anderen Anschlusselements aus der Blechebene entstanden sind.The two connection elements can thus be coupled together in the desired manner by a linear plug movement, wherein they are then secured by friction against each other. In this plug-in operation, the two freely projecting fingers of each connection element serve as a guide for each other connection element, since during the plugging operation, the freely projecting tongue with its free end protrudes into the slot between the two freely projecting fingers of the other connection element, which passes through the bending out of the tongue of the other connection element from the sheet plane have arisen.

Bevorzugte Ausführungsformen des erfindungsgemäßen Anschlusselements ergeben sich aus den Unteransprüchen, der folgenden Beschreibung sowie den Zeichnungen.Preferred embodiments of the connecting element according to the invention will become apparent from the dependent claims, the following description and the drawings.

So ist es gemäß einer Ausführungsform vorgesehen, dass das Anschlusselement einen Kontaktierungsabschnitt zur Anbindung eines elektrischen Leiters aufweist, der sich an einem den frei auskragenden Enden der Zunge und der Finger gegenüberliegendem Ende des Anschlusselements befindet. Der Kontaktierungsabschnitt dient dabei zur Anbringung eines elektrischen Leiters an dem Anschlusselement, was beispielsweise durch Crimpen, Schweißen oder Löten erfolgen kann. Dadurch, dass sich der Kontaktierungsabschnitt an dem in Steckrichtung hinterem Ende des Anschlusselements befindet, wird das Zusammenstecken zweier identischer Anschlusselemente durch den Kontaktierungsabschnitt nicht beeinträchtigt. Vielmehr gestattet es diese Ausgestaltung, dass sich zwei identische Anschlusselemente mit dem jeweiligen vorderen Ende der frei auskragenden Finger voraus durch eine reine lineare Steckbewegung miteinander verbinden lassen. Hierzu benötigt ein Monteur keine Sicht auf das Anschlusselement, wodurch es sich vorzugsweise auch zur Blindmontage eignet.Thus, according to one embodiment, provision is made for the connection element to have a contacting section for connecting an electrical conductor, which is located on an end of the connection element opposite the free-projecting ends of the tongue and the fingers. The contacting section serves to attach an electrical conductor to the connection element, which can be done for example by crimping, welding or soldering. Characterized in that the contacting portion is located at the rear end in the insertion direction of the connection element, the mating of two identical connection elements is not affected by the contacting section. Rather, this configuration allows two identical connection elements with the respective front end of the cantilevered Finger can be connected by a pure linear plug movement. For this purpose, a fitter needs no view of the connection element, whereby it is preferably also suitable for blind mounting.

Gemäß einer weiteren Ausführungsform können die freien Enden der beiden frei auskragenden Finger durch einen Stegabschnitt miteinander verbunden sein, der sich auf der der ersten Seite des Blechs gegenüberliegenden zweiten Seite des Blechs befindet. Der Stegabschnitt ist dabei aus dem Metallblech gefertigt und aus der Blechebene herausgebogen, so dass der zwischen den beiden Fingern gebildete Spalt in Steckrichtung nach vorne offen ist. Durch den in Rede stehenden Stegabschnitt erfolgt eine Stabilisierung und Kopplung der Finger, so dass beide Finger stets annähernd gleich große Kontaktkräfte erfahren.According to a further embodiment, the free ends of the two cantilevered fingers may be interconnected by a web portion located on the second side of the metal sheet opposite the first side of the metal sheet. The web portion is made of the metal sheet and bent out of the sheet metal plane, so that the gap formed between the two fingers in the insertion direction is open to the front. The web section in question stabilizes and couples the fingers so that both fingers always experience approximately equal contact forces.

Gemäß einer weiteren bevorzugten Ausführungsform kann die frei auskragende Zunge einen aus der Blechebene herausgebogenen Rampenabschnitt und einen sich in einer zur Blechebene parallelen Ebene erstreckenden Hintergreifungsabschnitt aufweisen, der von dem Rampenabschnitt frei auskragt. Der Hintergreifungsabschnitt bildet somit in Verbindung mit dem Rampenabschnitt einen Federarm, welcher dazu dient, eine Klemmkraft auf ein mit dem erfindungsgemäßen Anschlusselement zu koppelndes (identisches) Anschlusselement auszuüben. Während des Zusammensteckens zweier identischer Anschlusselemente dringen dabei zunächst die Hintergreifungsabschnitte in den Spalt ein, der zwischen den beiden Fingern des jeweils anderen Anschlusselements gebildet wird, bis der Hintergreifungsabschnitt des jeweiligen Anschlusselements auf den Rampenabschnitt des jeweils anderen Anschlusselements aufreitet und durch diesen ausgelenkt wird. Bei weiter fortschreitendem Steckvorgang wird somit das jeweilige Anschlusselement zwischen der Zunge und den beiden Fingern des jeweils anderen Anschlusselements festgeklemmt, wodurch die beiden Anschlusselemente reibschlüssig aneinander gesichert sind.According to a further preferred embodiment, the cantilevered tongue can have a ramp section bent out of the plane of the sheet metal and a rear engagement section extending in a plane parallel to the sheet plane and projecting freely from the ramp section. The Hintergreifungsabschnitt thus forms in conjunction with the ramp portion a spring arm, which serves to exert a clamping force on a to be coupled with the connecting element according to the invention (identical) connection element. During the mating of two identical connection elements penetrate the first Hintergreifungsabschnitte in the gap, which is formed between the two fingers of the other connection element until the Hintergreifungsabschnitt of the respective connection element aufreit on the ramp portion of the other connection element and is deflected by this. As the plugging process progresses, the respective connecting element between the tongue and the tongue is thus released clamped fingers of each other connecting element, whereby the two connection elements are frictionally secured together.

Gemäß einer bevorzugten Ausführungsform kann der Hintergreifungsabschnitt an seinem freien Ende ebenfalls mit einer schrägen Fläche ausgebildet sein, die in die gleiche Richtung geneigt ist, wie der aus der Blechebene herausgebogene Rampenabschnitt der Zunge. Diese Ausführungsform erweist sich dahingehend als vorteilhaft, dass beim Zusammenstecken zweier identischer Anschlusselemente die am freien Ende des Hintergreifungsabschnitts vorgesehene schräge Fläche auf dem aus der Blechebene herausgebogenen Rampenabschnitt des anderen Anschlusselements aufreitet. Hierdurch wird bei fortgesetzter Steckbewegung die Zunge des Anschlusselements zunehmend ausgelenkt, so dass das jeweils andere Anschlusselement zwischen der ausgelenkten Zunge und den beiden Fingern des einen Anschlusselements festgeklemmt wird.According to a preferred embodiment, the Hintergreifungsabschnitt may also be formed at its free end with an inclined surface which is inclined in the same direction as the bent out of the plane of the sheet ramp portion of the tongue. This embodiment proves to be advantageous in that when mating two identical connection elements provided at the free end of the Hintergreifungsabschnitts inclined surface on the bent out of the sheet plane ramp section of the other connection element treads. As a result, the tongue of the connection element is increasingly deflected with continued insertion movement, so that the respective other connection element between the deflected tongue and the two fingers of a connection element is clamped.

Da die Kontaktauswölbung leicht schräg stehende Flanken aufweisen, kann es passieren, dass zwei Anschlusselemente, die sich nur entlang dieser schräg stehenden Flanken berühren, wieder voneinander infolge der Federvorspannung lösen, welche von den Fingern des jeweils einen Anschlusselements über die schräg stehenden Flanken auf das jeweils andere Anschlusselement ausgeübt wird. Um dieser Gefahr eines unbeabsichtigten Lösens zweier miteinander verbundender Anschlusselemente entgegenzuwirken, kann jede der Kontaktauswölbungen eine längliche Gestalt aufweisen und so ausgerichtet sein, dass die jeweiligen einander zugeordneten Kontaktauswölbungen zweier Anschlusselemente gekreuzt aufeinander zu liegen kommen und somit einen Überschneidungsbereich bilden, in dem sie sicher in Reibschluss miteinander stehen. Beispielsweise kann jeder Finger zwei in Fingerlängsrichtung zueinander beabstandete längliche Auswölbungen aufweisen, welche schräg, vorzugsweise unter 45° in der Längsrichtung ausgerichtet sind oder welche derart ausgerichtet sind, dass eine Auswölbung unter 0° und die andere Auswölbung unter 90° zur Fingerlängsrichtung ausgerichtet ist.Since the contact bulge have slightly inclined flanks, it may happen that two connection elements, which only touch along these inclined flanks, again from each other due to the spring preload dissolve, which of the fingers of the one connecting element on the inclined flanks on each other connection element is exercised. To counteract this risk of unintentional release of two interconnected connection elements, each of the contact bulges may have an elongated shape and be aligned so that the respective mutually associated contact bulges of two connection elements come crossed to lie on one another and thus form an overlap area in which they are safe in frictional engagement standing together. For example, each finger two spaced apart in the finger longitudinal direction have elongated bulges, which are aligned obliquely, preferably at 45 ° in the longitudinal direction or which are aligned such that a bulge is oriented at 0 ° and the other bulge at 90 ° to the longitudinal direction of the finger.

Da dadurch, dass während des Zusammensteckens zweier miteinander zu verbindender Anschlusselemente die Flanken der an den jeweiligen Fingern vorgesehenen Kontaktauswölbungen aufeinander aufreiten, die Steckkraft, die erforderlich ist, um die Finger der Anschlusselemente auseinander zu spreizen, sprunghaft ansteigt, ist es gemäß einer weiteren Ausführungsform vorgesehen, dass jeder Finger zwei in Fingerlängsrichtung zueinander beabstandete längliche Kontaktauswölbungen aufweist, wobei die beiden in Steckrichtung vorderen Kontaktauswölbungen der beiden Finger und/oder die beiden in Steckrichtung hinteren Kontaktauswölbungen der beiden Finger unterschiedlich weit vom freien Ende des jeweiligen Fingers beabstandet sind. Hierdurch kann sichergestellt werden, dass die schräg stehenden Flanken zweier einander zugeordneter Kontaktauswölbungen zweier miteinander zu verbindender Anschlusselemente während des Zusammensteckens nicht gleichzeitig sondern nacheinander aufeinander treffen, wodurch die erforderlichen Steckkräfte klein gehalten werden können.Since, as a result of the fact that, during the mating of two connection elements to be connected, the flanks of the contact protrusions provided on the respective fingers are ratcheting, the insertion force which is required to spread apart the fingers of the connection elements increases sharply, it is provided according to a further embodiment in that each finger has two elongate contact bulges spaced apart from one another in the longitudinal direction of the fingers, wherein the two contact bulges of the two fingers in the insertion direction and / or the two contact protrusions of the two fingers are spaced differently far from the free end of the respective finger. In this way it can be ensured that the inclined flanks of two mutually associated contact bulges of two connecting elements to be connected to one another do not simultaneously but successively hit one another during the mating, whereby the required insertion forces can be kept small.

Gemäß einer weiteren Ausführungsform ist es vorgesehen, dass die frei auskragende Zunge an ihrem freien Ende eine Auswölbung aufweist, welche sich auf der zweiten Seite des Blechs erstreckt. Somit ist auch an der frei auskragenden Zunge eine definierte Kontaktstelle vorgesehen, über die die Kontaktierung und Stromübertragung zu dem jeweils anderen Anschlusselement erfolgen kann. Die Kontaktierung zweier miteinander zu verbindender elektrischer Anschlusselemente erfolgt somit ausschließlich punktuell über die an den Fingern und den Zungen vorgesehenen Auswölbungen, wodurch die quantitative Verteilung des Stromflusses über das Anschlusselement gezielt beeinflusst werden kann.According to a further embodiment, it is provided that the cantilevered tongue has at its free end a bulge which extends on the second side of the sheet. Thus, a defined contact point is also provided on the cantilevered tongue, via which the contacting and power transmission to the respective other connection element can take place. The contacting of two electrical connection elements to be connected to each other is thus exclusively punctual on the provided on the fingers and the tongues Bulges, whereby the quantitative distribution of the current flow through the connection element can be selectively influenced.

Im Falle, dass über das erfindungsgemäße Anschlusselement mehr Strom übertragen werden soll, als eine einzige Anordnung aus Zunge und Fingern zu übertragen in der Lage ist, ist es gemäß einer weiteren Ausführungsform vorgesehen, dass das Anschlusselement mehrere nebeneinander und/oder hintereinander befindliche Anordnungen aus Zunge und Fingern gemäß den voranstehenden Ausführungen aufweist. Da hierbei alle Finger und Zungen gleich orientiert sind und parallel zueinander verlaufen, können auf die einzelnen Anordnungen aus Zunge und Fingern entweder mehrere separate Anschlusselemente gemäß der vorliegenden Erfindung oder ein Anschlusselement eingesteckt werden, welches ebenfalls mehrere nebeneinander befindliche Anordnungen aus Zunge und Fingern aufweist. Beispielsweise ist es möglich, eine Stromschiene mit einer Vielzahl nebeneinander befindlicher Anordnungen aus Zunge und Fingern auszubilden, wobei auf jede dieser Anordnungen aus Zunge und Finger dann ein erfindungsgemäßes Anschlusselement aufgesteckt werden kann, welches zumindest eine Anordnung aus Zunge und Fingern aufweist.In the event that more power is to be transmitted via the connecting element according to the invention than a single arrangement of tongue and fingers is able to transmit, it is provided according to a further embodiment that the connecting element a plurality of side by side and / or successively located arrangements of tongue and fingers as described above. Since in this case all fingers and tongues are oriented the same and run parallel to one another, either several separate connection elements according to the present invention or a connection element can be plugged into the individual arrangements of tongue and fingers, which also has several juxtaposed arrangements of tongue and fingers. For example, it is possible to form a bus bar with a plurality of juxtaposed arrangements of tongue and fingers, wherein each of these arrangements of tongue and finger then a connection element according to the invention can be plugged, which has at least one arrangement of tongue and fingers.

Bei der Ausführungsform, bei der das Anschlusselement mehrere hintereinander befindliche Anordnungen aus Zunge und Fingern aufweist, kann es sich als vorteilhaft erweisen, dass sich eine in Steckrichtung hintere Anordnung aus Zunge und Fingern oberhalb der davor befindlichen Anordnung aus Zunge und Fingern erstreckt. Die Zunge der hinteren Anordnung aus Zunge und Fingern wird somit nicht durch die Zunge der vorderen Anordnung aus Zunge und Fingern in Steckrichtung verdeckt, so dass auch auf die hintere Anordnung aus Zunge und Fingern ein erfindungsgemäßes Anschlusselement ungehindert durch eine rein lineare Steckbwegung aufgesteckt werden kann.In the embodiment in which the connecting element has a plurality of successively arranged arrangements of tongue and fingers, it may prove to be advantageous that extends in the insertion direction rear arrangement of tongue and fingers above the front of the arrangement of tongue and fingers. The tongue of the rear arrangement of tongue and fingers is thus not covered by the tongue of the front arrangement of tongue and fingers in the insertion direction, so that even on the rear arrangement of tongue and fingers an inventive Connection element unhindered by a purely linear Steckbwegung can be plugged.

Gemäß einer weiteren Ausführungsform ist das erfindungsgemäße Anschlusselement von einem in Steckrichtung offenen Gehäuseelement umgeben, welches ausgebildet ist, um in Steckrichtung eine Kopplung mit einem identischen Gehäuseelement zu ermöglichen. Das Gehäuseelement kann dabei geeignete Formschlusselemente wie beispielsweise Rasthaken oder dergleichen aufweisen, um zusätzlich zu der Reibschlussverbindung, die über das erfindungsgemäße Anschlusselemente erreicht wird, einen Formschluss zwischen zwei miteinander zu verbindender Anschlusselementen zu erzeugen.According to a further embodiment, the connection element according to the invention is surrounded by a housing element which is open in the plug-in direction and which is designed to enable a coupling with an identical housing element in the insertion direction. In this case, the housing element may have suitable form-locking elements, such as catch hooks or the like, in order to produce a positive connection between two connection elements to be connected to one another in addition to the frictional connection, which is achieved via the connection elements according to the invention.

Dadurch, dass sich die Zunge und die Finger des erfindungsgemäßen Anschlusselements jeweils in die gleiche Richtung erstrecken, kann das erfindungsgemäße Anschlusselement mit einem identischen Anschlusselement durch einen rein linearen Steckvorgang gekoppelt werden. Darüber hinaus kann das erfindungsgemäße Anschlusselement in der zuvor erläuterten Art und Weise mit mehreren Anordnungen aus Zunge und Fingern ausgestaltet werden, so dass über das erfindungsgemäße Anschlusselement stärkere Ströme übertragen werden können, als dies mit einem Anschlusselement mit einer einzigen Anordnung aus Zunge und Fingern möglich wäre. Darüber hinaus lässt sich das erfindungsgemäße Anschlusselement kostengünstig produzieren, da es sich als Stanzteil aus einem einzigen Metallblech fertigen lässt und somit über keine zusätzlichen Teile wie beispielsweise Kontaktfedern oder dergleichen verfügt.Due to the fact that the tongue and the fingers of the connecting element according to the invention each extend in the same direction, the connecting element according to the invention can be coupled to an identical connecting element by a purely linear plugging operation. In addition, the connection element according to the invention can be configured in the manner previously described with multiple arrangements of tongue and fingers, so that over the connection element according to the invention stronger currents can be transmitted, as would be possible with a connection element with a single arrangement of tongue and fingers , In addition, the connection element according to the invention can be produced inexpensively, since it can be produced as a stamped part from a single metal sheet and thus has no additional parts such as contact springs or the like.

Die Fig. 1 zeigt zwei identische, erfindungsgemäße elektrische Anschlusselemente 10, welche mit ihrem in Steckrichtung vorderen Ende 12 einander zugewandt und senkrecht zur Blechebene des Blechs 16, aus dem die beiden Anschlusselemente 10 gefertigt sind, versetzt zueinander sind. Die beiden Anschlusselemente 10 sind aus einem elektrisch leitfähigen Metallblech 16 mit federnden Eigenschaften aus beispielsweise Kupfer- oder Aluminiumlegierungen durch Ausstanzen gefertigt und weisen jeweils eine frei auskragende Zunge 14 auf, die aus Blechebene auf eine erste Seite A des Blechs herausgebogen ist und sich in einer zur Blechebene parallelen Ebene erstreckt. Durch das Herausbiegen der Zunge 14 aus der Blechebene werden zwei in Steckrichtung des Anschlusselements 12 frei auskragende Finger 17, 18 gebildet, welche durch einen länglichen Spalt 20, der am vorderen Ende 12 des Anschlusselements 10 offen ist, zueinander beabstandet sind. Die beiden Finger 17, 18 erstrecken sich somit in der Blechebene parallel zu der frei auskragenden Zunge 14 und definieren in Steckrichtung das vordere Ende 12 des Anschlusselements 10.The Fig. 1 shows two identical, electrical connection elements 10 according to the invention, which with their front end in the insertion direction 12 facing each other and perpendicular to the sheet metal plane of the sheet 16, from which the two connection elements 10 are made offset from each other. The two connection elements 10 are made of an electrically conductive metal sheet 16 with resilient properties of, for example, copper or aluminum alloys by punching and each have a cantilevered tongue 14, which is bent out of sheet metal plane on a first side A of the sheet and extending in a plane parallel to the sheet plane. By bending the tongue 14 out of the plane of the sheet, two fingers 17, 18 projecting freely in the insertion direction of the connection element 12 are formed, which are spaced apart by an elongated gap 20 which is open at the front end 12 of the connection element 10. The two fingers 17, 18 thus extend in the sheet plane parallel to the cantilevered tongue 14 and define in the insertion direction, the front end 12 of the connecting element 10th

An dem gegenüberliegenden hinteren Ende 13 weist das Anschlusselement 12 einen flächigen Kontaktierungsabschnitt 22 auf, welcher zur Anbindung eines elektrischen Leiters (nicht dargestellt) dient, der daran beispielsweise durch Crimpen, Löten oder Schweißen befestigt werden kann.At the opposite rear end 13, the connecting element 12 has a flat contacting section 22, which serves for the connection of an electrical conductor (not shown), which can be attached thereto, for example by crimping, soldering or welding.

Die in Steckrichtung X vorderen Enden der beiden frei auskragenden Finger 17, 18 der beiden Anschlusselemente 10 sind in der dargestellten Ausführungsform durch einen Stegabschnitt 24 miteinander verbunden, der sich auf der der ersten Seite A des Blechs 16 gegenüberliegenden zweiten Seite B des Blechs 16 befindet. Der Stegabschnitt 24 wird dabei durch Umbiegen des vorderen Endes des Blechs 16 gebildet und definiert somit zusammen mit den freien Enden der Finger 17, 18 das vordere Ende 12 des Anschlusselements 10. Da sich der Stegabschnitt 24 auf der zweiten Blechseite B unterhalb der Blechebene erstreckt, ist der Spalt 20 zwischen den Fingern 17, 18 am vorderen Ende 12 des Anschlusselements 10 offen und dient somit gewissermaßen als Aufnahmeöffnung für die Zunge 14 des jeweils anderen Anschlusselements 10.The front in the insertion direction X ends of the two cantilevered fingers 17, 18 of the two connecting elements 10 are connected in the illustrated embodiment by a web portion 24 which is located on the first side A of the sheet 16 opposite second side B of the sheet 16. The web portion 24 is formed by bending the front end of the sheet 16 and thus defines together with the free ends of the fingers 17, 18, the front end 12 of the connecting element 10. Since the web portion 24 extends on the second sheet side B below the plane of the sheet, the gap 20 between the fingers 17, 18 at the front end 12 of the connection element 10 is open and thus effectively serves as a receiving opening for the tongue 14 of the respective other connection element 10th

Die Zunge 14 des Anschlusselements 10 weist einen aus der Blechebene herausgebogenen Rampenabschnitt 26 und einen sich in einer zur Blechebene parallelen Ebene erstreckenden Hintergreifungsabschnitt 28 auf, der von dem Rampenabschnitt 26 frei auskragt. Die Zunge 14 bildet somit einen elastischen Federarm, welcher dazu dient, um das andere Anschlusselement 10 zwischen den beiden Fingern 17, 18 und der Zunge 14 selbst festzuklemmen, wie dies nachfolgend genauer erläutert wird. In der dargestellten Ausführungsform weist der Hintergreifungsabschnitt 28 an seinem freien Ende eine schräge Fläche 30 auf, welche in die gleiche Richtung geneigt ist, wie der aus der Blechebene herausgebogene Rampenabschnitt 26 der Zunge 14.The tongue 14 of the connecting element 10 has a bent out of the plane of the sheet ramp portion 26 and extending in a plane parallel to the plane parallel to the rear engaging portion 28 which projects freely from the ramp portion 26. The tongue 14 thus forms an elastic spring arm, which serves to clamp the other connecting element 10 between the two fingers 17, 18 and the tongue 14 itself, as will be explained in more detail below. In the illustrated embodiment, the Hintergreifungsabschnitt 28 at its free end on an inclined surface 30 which is inclined in the same direction as the bent out of the plane of the sheet ramp portion 26 of the tongue 14th

Außerdem weist die Zunge 14 an ihrem freien Ende eine Auswölbung auf, welche sich auf der zweiten Seite B des Blechs 16 erstreckt, aus dem die Zunge 14 gebogen wurde.In addition, the tongue 14 at its free end on a bulge, which extends on the second side B of the sheet 16, from which the tongue 14 has been bent.

Auch die Finger 17, 18 weisen Kontaktauswölbungen 34 auf, welche in Fingerlängsrichtung zueinander beabstandet sind. Die Kontaktauswölbungen 34 der Finger 17, 18 erstrecken sich dabei auf der ersten Seite A des Blechs 16, in das sie ausgehend von der zweiten Seite B eingeprägt wurden, wie dies anhand des rechten Anschlusselements 10 der Fig. 1 erkannt werden kann. Diese Kontaktauswölbungen 34 weisen dabei eine längliche, ovale Gestalt auf und sind jeweils unter 45° zur Fingerlängsrichtung ausgerichtet, wodurch sichergestellt werden kann, dass die jeweiligen einander zugeordneten Kontaktauswölbungen 34 zweier Anschlusselemente 10 gekreuzt aufeinander zu liegen kommen und somit einen Überschneidungsbereich bilden, in dem die Anschlusselemente 10 sicher in Reibschluss miteinander stehen.The fingers 17, 18 have contact bulges 34, which are spaced apart in the finger longitudinal direction. The contact bulges 34 of the fingers 17, 18 extend on the first side A of the sheet 16, in which they were embossed starting from the second side B, as shown by the right-hand connection element 10 of the Fig. 1 can be recognized. These contact bulges 34 in this case have an elongated, oval shape and are each aligned at 45 ° to the finger longitudinal direction, which can ensure that the respective associated contact bulges 34 of two connection elements 10 come crossed to lie on each other and thus form an overlap region in which the Connection elements 10 are securely in frictional engagement with each other.

Im Folgenden wird nun die Herstellung einer elektrischen Verbindung unter Verwendung zweier identischer Anschlusselemente 10 erläutert. Wie in der Fig. 1 dargestellt ist, werden hierzu zunächst zwei identische Anschlusselemente 10 mit ihren vorderen Enden 12 beabstandet zueinander angeordnet, wobei die erste Blechseite A des einen Anschlusselements 10 der ersten Blechseite A des anderen Anschlusselements 10 zugewandt ist. Die beiden Anschlusselemente 10 sind dabei annähernd derart orientiert und ausgerichtet, dass das freie Ende der Zunge 14 des jeweiligen Anschlusselements 10 in den Spalt 20 zwischen den Fingern 17, 18 des jeweils anderen Anschlusselements 10 gelangt, wenn damit begonnen wird, die beiden Anschlusselemente 10 in Steckrichtung X aufeinander zu zu bewegen. Im Falle, dass hierbei die beiden Anschlusselemente 10 etwas zu stark versetzt zueinander angeordnet sein sollten, wie dies in der Fig. 1 dargestellt ist, gelangen dabei die schrägen Flächen 30 der Zungen 14 der beiden Anschlusselemente 10 in Anlage, wodurch bei fortgesetzter Steckbewegung die beiden Anschlusselemente 10 senkrecht zur Blechebene aufeinander zu bewegt werden, so dass die Zunge 14 des jeweiligen Anschlusselements 10 in dem Spalt 20 des jeweils anderen Anschlusselements 10 zu liegen kommt, wie dies in der Fig. 2 dargestellt ist. Die schrägen Flächen 30 fungieren somit gewissermaßen als Einführhilfe, wodurch sich das erfindungsgemäße Anschlusselement 10 auch zur Blindmontage eignet.The production of an electrical connection using two identical connection elements 10 will now be explained below. Like in the Fig. 1 For this purpose, two identical connection elements 10 with their front ends 12 are arranged at a distance from one another, wherein the first sheet-metal side A of one connection element 10 faces the first sheet-metal side A of the other connection element 10. The two connection elements 10 are approximately oriented and aligned such that the free end of the tongue 14 of the respective connection element 10 passes into the gap 20 between the fingers 17, 18 of the other connection element 10 when it starts, the two connection elements 10 in Plug direction X to each other to move. In the case that in this case the two connection elements 10 should be slightly too offset from each other, as in the Fig. 1 is shown, thereby reach the inclined surfaces 30 of the tongues 14 of the two connecting elements 10 in abutment, whereby the two connecting elements 10 are moved perpendicular to the sheet plane toward each other with continued insertion movement, so that the tongue 14 of the respective connection element 10 in the gap 20 of each other terminal element 10 comes to rest, as shown in the Fig. 2 is shown. The inclined surfaces 30 thus effectively act as an insertion aid, whereby the connecting element 10 according to the invention is also suitable for blind mounting.

Wird ausgehend von der in der Fig. 2 dargestellten Stellung damit fortgefahren, die beiden Anschlusselemente 10 in Steckrichtung X aufeinander zu zu bewegen, führt dies dazu, dass die schräge Fläche 30 der Zunge 14 des jeweiligen Anschlusselements 10 auf dem Rampenabschnitt 26 der Zunge 14 des jeweils anderen Anschlusselements aufreitet. Hierdurch werden die Zungen 14 der beiden Anschlusselemente 10 elastisch ausgelenkt und erzeugen somit eine Klemmkraft auf den Kontaktierungsabschnitt 22 des jeweils anderen Anschlusselements 10, so dass das jeweilige Anschlusselement 10 zwischen den Fingern 17, 18 und der Zunge 14 des jeweils anderen Anschlusselements 10 durch Klemmung bzw. über Reibschluss gesichert ist.Is based on the in the Fig. 2 shown position continued to move the two connection elements 10 in the insertion direction X to each other, this causes the inclined surface 30 of the tongue 14 of the respective connection element 10 on the ramp portion 26 of the tongue 14 of the respective other connection element treads. As a result, the tongues 14 of the two connection elements 10 are elastically deflected and thus generate a clamping force on the contacting section 22 of the respective other connection element 10, so that the respective connection element 10 between the fingers 17, 18 and the tongue 14 of the respective other connection element 10 is secured by clamping or by frictional engagement.

In der in der Fig. 3 dargestellten Endstellung befinden sich die länglichen, ovalen Kontaktauswölbungen 34 der beiden Anschlusselemente 10 kreuzweise übereinander, wodurch die beiden Anschlusselemente 10 senkrecht zur Blechebene entgegen der Federkraft der beiden Zungen 14 auseinandergepresst werden, wodurch der Reibschluss zwischen den beiden Anschlusselementen 10 gesteigert wird. Durch die definierten Kontaktstellen in Form der Kontaktauswölbungen 32, 34 wird jedoch nicht nur in der gewünschten Weise der Reibschluss zwischen den beiden elektrischen Anschlusselementen 10 erhöht; vielmehr kann durch die gezielte Anordnung der Kontaktauswölbungen 32, 34 ein gleichmäßig verteilter Stromfluss über die elektrischen Anschlusselemente 10 erreicht werden, wodurch deren Stromfestigkeit gezielt beeinflusst werden kann.In the in the Fig. 3 illustrated end position, the elongated, oval contact bulges 34 of the two connection elements 10 are crosswise one above the other, whereby the two connection elements 10 are pressed against the spring force of the two tongues 14 perpendicular to the sheet plane, whereby the frictional engagement between the two connection elements 10 is increased. Due to the defined contact points in the form of the contact bulges 32, 34, however, not only in the desired manner, the frictional engagement between the two electrical connection elements 10 is increased; Rather, a uniformly distributed current flow over the electrical connection elements 10 can be achieved by the targeted arrangement of the contact bulges 32, 34, whereby their current strength can be influenced in a targeted manner.

Da durch das gleichzeitige Aufeinandertreffen der schräg stehenden Flanken der Kontaktauswölbungen 32, 34 sprunghaft die Kraft, die zum Zusammenstecken der beiden Anschlusselemente 10 erforderlich ist, zunimmt, können die beiden in Steckrichtung vorderen Kontaktauswölbungen 34 der beiden Finger 17, 18 unterschiedlich weit vom freien Ende des jeweiligen Fingers 17, 18 beabstandet sein, wie dies bei der in der Fig. 4 dargestellten Ausführungsform vorgesehen ist. Wie dieser Darstellung entnommen werden kann, ist die Kontaktauswölbung 34 des Fingers 17 etwas weiter vom vorderen Ende des Anschlusselements 10 beabstandet als die Kontaktauswölbung 34 des Fingers 18, wie dies in der Figur anhand der gestrichelten Linie ohne weiteres erkennbar ist. Dieser Versatz der vorderen Kontaktauswölbungen 34 hat zur Folge, dass beim Zusammenstecken zweier identischer Anschlusselemente 10 die hinteren Kontaktauswölbungen 34 des jeweiligen Anschlusselements 10 nacheinander mit den versetzt zueinander angeordneten vorderen Kontaktauswölbungen 34 des jeweils anderen Anschlusselements 10 in Kontakt gelangen, wodurch die erforderliche Steckkraft zweier miteinander zu verbindender Anschlusselemente 10 weniger stark zunimmt.Since by the simultaneous meeting of the inclined flanks of the contact bulges 32, 34 abruptly increases the force required for mating the two connection elements 10, the two front in the insertion direction Kontaktauswölbungen 34 of the two fingers 17, 18 different far from the free end of the each finger 17, 18 spaced, as in the in the Fig. 4 illustrated embodiment is provided. As can be seen from this illustration, the contact protrusion 34 of the finger 17 is spaced slightly farther from the front end of the terminal 10 than the contact protrusion 34 of the finger 18, as readily apparent from the broken line in the figure. This offset of the front contact bulges 34 has the consequence that when mating two identical connection elements 10, the rear contact bulges 34 of the respective connection element 10 in succession with the mutually offset front contact bulges 34 of the other connecting element 10 come into contact, whereby the required insertion force of two connecting elements 10 to be interconnected increases less.

Da die vorderen Kontaktauswölbungen 34 gemäß der Fig. 4 unterschiedlich weit vom freien Ende der jeweiligen Finger 17, 18 entfernt sind, ist es bei dieser Ausführungsform vorgesehen, dass diese Kontaktauswölbungen 34 unter 90° zur Fingerlängsrichtung ausgerichtet sind, wohingegen die hinteren Kontaktauswölbungen 34 parallel zur Fingerlängsrichtung ausgerichtet sind. Der Versatz der vorderen Kontaktauswölbungen 34 wird somit durch die Längenerstreckung der hinteren Kontaktauswölbungen 34 des jeweils anderen Anschlusselements 10 ausgeglichen, wodurch sichergestellt werden kann, dass im Endzustand eine Kontaktierung über alle Kontaktauswölbungen 34 erfolgt.Since the front contact bulges 34 according to the Fig. 4 are far away from the free end of the respective fingers 17, 18, it is provided in this embodiment that these contact bulges 34 are aligned at 90 ° to the finger longitudinal direction, whereas the rear contact bulges 34 are aligned parallel to the finger longitudinal direction. The offset of the front contact bulges 34 is thus compensated by the longitudinal extent of the rear contact bulges 34 of the other connecting element 10, which can be ensured that in the final state contacting over all contact bulges 34 takes place.

Sollte es erforderlich sein, über das in der Fig. 4 dargestellte Anschlusselement einen stärkeren Strom zu übertragen, als dieses zu übertragen in der Lage ist, kann das Anschlusselement 10 mehrere nebeneinander befindliche Anordnungen aus Zunge und Finger aufweisen, wie dies in der Fig. 5 dargestellt ist.Should it be necessary over that in the Fig. 4 The connecting element 10 can have a plurality of juxtaposed arrangements of tongue and finger, as shown in FIG Fig. 5 is shown.

Um stärkere Ströme über das erfindungsgemäße Anschlusselement 10 übertragen zu können, kann das Anschlusselement 10 auch mehrere hintereinander befindliche Anordnungen aus Zunge und Fingern aufweisen, wie dies in der Fig. 6 dargestellt ist. In diesem Falle erstreckt sich die in Steckrichtung X hintere Anordnung aus Zunge und Fingern oberhalb der davor befindlichen Anordnung aus Zunge und Fingern, da andernfalls die freie Zugänglichkeit der hinteren Anordnung aus Zunge und Fingern in Steckrichtung X durch die vordere Zunge 14 eingeschränkt werden würde.In order to be able to transmit stronger currents via the connection element 10 according to the invention, the connection element 10 can also have a plurality of arrangements of tongue and fingers located one behind the other, as shown in FIG Fig. 6 is shown. In this case, the rear in the insertion direction X arrangement of tongue and fingers extends above the front of the arrangement of tongue and fingers, otherwise the free accessibility of the rear arrangement of tongue and fingers in the insertion direction X would be limited by the front tongue 14.

Auch wenn dies nicht dargestellt ist, lassen sich die in den Fig. 5 und 6 dargestellten Ausführungsformen miteinander kombinieren, wodurch ein Anschlusselement entsteht, das mehrere nebeneinander und hintereinander befindliche Anordnungen aus Zunge und Fingern aufweist, wobei auch in diesem Falle die jeweils hintere Anordnung aus Zunge und Fingern sich oberhalb der davor befindlichen Anordnung aus Zunge und Fingern erstreckt.Even if this is not shown, can be in the Fig. 5 and 6 combined embodiments, whereby a connection element is formed, which has a plurality of juxtaposed and successively located arrangements of tongue and fingers, in which case the respective rear arrangement of tongue and fingers extends above the front of the arrangement of tongue and fingers.

Eine elektrische Verbindung lässt sich mit dem in der Fig. 5 dargestellten Anschlusselement beispielsweise herstellen, indem es mit einem identischen Anschlusselement gekoppelt wird. Alternativ dazu lässt sich das in der Fig. 5 dargestellte Anschlusselement auch mit zwei Anschlusselementen gemäß Fig. 4 koppeln, wodurch das in der Fig. 5 dargestellte Anschlusselement gewissermaßen als Stromschiene dient.An electrical connection can be with the in the Fig. 5 For example, manufacture connecting element shown by being coupled to an identical connection element. Alternatively, this can be in the Fig. 5 shown connection element with two connection elements according to Fig. 4 couple, which in the Fig. 5 shown connecting element effectively serves as a busbar.

Auch das in der Fig. 6 dargestellte Anschlusselement lässt sich entweder mit einem identischen Anschlusselement koppeln. Alternativ dazu kann auch das in der Fig. 6 dargestellte Anschlusselement mit zwei einzelnen Anschlusselementen gemäß Fig. 1 gekoppelt werden, wodurch das Anschlusselement der Fig. 6 gewissermaßen als Stromschiene dient. Selbstverständlich können auch mehr als zwei Anordnungen aus Zunge und Fingern nebeneinander und/oder hintereinander an einem einzigen Anschlusselement vorgesehen werden, wodurch dessen Stromschienencharakter noch deutlicher in Erscheinung tritt.Also in the Fig. 6 shown connection element can be coupled either with an identical connection element. Alternatively, also in the Fig. 6 illustrated connection element with two individual connection elements according to Fig. 1 be coupled, whereby the connecting element of the Fig. 6 effectively serves as a busbar. Of course, more than two arrangements of tongue and fingers can be provided side by side and / or one behind the other on a single connection element, whereby its busbar character occurs even more clearly in appearance.
