Abstract

The connector has a tension spring (1) bent into a tubular shape with a clamping arm and a contact arm (2,3). A current rail (busbar) (4) in contact with the spring passes through a window (5) in the clamping arm (2). The lower surface (7) of the window opening forms a clamping region for clamping a conductor (11) which is pressed against the current rail. The end region (8) of the clamping arm immediately following the lower side of the window opening is cropped.

Description

Die vorliegende Erfindung betrifft einen Zugfederanschluß für elektrische Leiter gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a tension spring connection for electrical conductors the preamble of claim 1.

Ein Zugfederanschluß ist beispielsweise aus der DE-OS-39 11 459 bekannt.A tension spring connection is known for example from DE-OS-39 11 459.

Solche Zugfederanschlüsse finden mehr und mehr Verwendung, da sie gegenüber Schraubanschlüssen erhebliche Vorteile bieten.Such spring-cage connections are used more and more because they face each other Screw connections offer considerable advantages.

So ist neben einer einfacheren Handhabung vor allem zu erwähnen, daß, unabhängig vom Fließverhalten des Leiters, auf diesen ein ständiger Druck ausgeübt wird, der auftretenden Auszugskräften entgegenwirkt.In addition to simpler handling, it should above all be mentioned that, independently from the flow behavior of the conductor, on which a constant pressure is exerted counteracting pull-out forces.

Darüber hinaus besteht eine weitere Forderung darin, eine gasdichte Verbindung zwischen der Zugfeder bzw. der Stromschiene und dem Leiter zu schaffen, was neben den aufzubringenden Federkräften auch durch eine entsprechende Formgebung im Berührungsbereich erzielt wird. Another requirement is a gas-tight connection between the tension spring or the conductor rail and the conductor to create what next the spring forces to be applied also by appropriate shaping is achieved in the contact area.

Dabei ist eine möglichst hohe Flächenpressung gewünscht, die jedoch nicht zur Beschädigung des Leiters führen darf.The highest possible surface pressure is desired, but not to damage it of the leader.

Vor allem bei den immer kleiner werdenden Zugfederanschluß-Elementen kann die Federkraft der Zugfeder nicht beliebig erhöht werden, so daß zur Erhöhung der Flächenpressung die Minimierung der Druckflächen als einzige Alternative verbleibt.Especially with the increasingly smaller tension spring connection elements, the The spring force of the tension spring cannot be increased arbitrarily, so that to increase the surface pressure minimizing the printing area remains as the only alternative.

Allerdings ist zu beachten, daß, wie erwähnt, die Verbindung gasdicht sein soll.However, it should be noted that, as mentioned, the connection should be gas-tight.

Mittels der bekannten Zugfederanschlüsse ist eine Vergrößerung der Flächenpressung im Sinne einer Optimierung nicht möglich.The known tension spring connections increase the surface pressure not possible in the sense of optimization.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Zugfederanschluß der gattungsgemäßen Art so zu gestalten, daß die Flächenpressung im Verbindungsbereich zwischen der Zugfeder bzw. der Stromschiene und dem Leiter bei unveränderter Federkraft der Zugfeder, auch bei kleinsten Zugfederanschluß-Elementen, größtmöglich ist.The present invention is therefore based on the object of a tension spring connection of the generic type so that the surface pressure in Connection area between the tension spring or the busbar and the conductor with unchanged spring force of the tension spring, even with the smallest tension spring connection elements, is as big as possible.

Diese Aufgabe wird durch einen Zugfederanschluß gelöst, der die Merkmale des Anspruchs 1 aufweist.This object is achieved by a tension spring connection, which has the features of the claim 1 has.

Nunmehr erfolgt die Klemmung zwischen dem Klemmschenkel der Zugfeder und dem Leiter durch eine Klemmkante, die sich durch die Kröpfung des Klemmschenkels ergibt und die sich in den Leiter durch die Federbelastung eingräbt.Now the clamping between the clamping leg of the tension spring and the conductor through a clamping edge, which is characterized by the offset of the clamping leg results and which digs into the conductor by the spring load.

Gegenüber den bekannten Zugfederanschlüssen ist die Anpreßfläche erheblich verringert, so daß sich bei gleichbleibender Federkraft der Zugfeder eine um ein vielfaches erhöhte spezifische Flächenpressung ergibt.Compared to the known tension spring connections, the contact surface is considerably reduced, so that with constant spring force of the tension spring a multiple results in increased specific surface pressure.

Nach einem vorteilhaften Gedanken der Erfindung ist vorgesehen, daß die Stromschiene auf ihrer dem Leiter zugewandten Seite ebenfalls einen scharfkantigen Bereich aufweist, der quer zur Längsachse des Leiters verläuft und der sich gleichfalls beim Anpressen des Leiters in diesen eingräbt.According to an advantageous concept of the invention, it is provided that the busbar a sharp-edged area on the side facing the conductor has, which runs transversely to the longitudinal axis of the conductor and which is also digs into the conductor when pressed against it.

Diese scharfkantige Ausbildung kann beispielsweise dadurch erreicht werden, daß die Stromschiene eine zungenartige Ausstanzung aufweist, deren freies Ende in Richtung des Leiters gebogen ist, wodurch sich eine scharfe Klemmkante ergibt.This sharp-edged design can be achieved, for example, in that the busbar has a tongue-like punching, the free end in Is bent towards the conductor, which results in a sharp clamping edge.

Nach einem weiteren Gedanken der Erfindung ist vorgesehen, daß diese Klemmkante der Zunge im Verhältnis zur Klemmkante des Fensterausschnitts versetzt angeordnet ist. According to a further idea of the invention it is provided that this clamping edge the tongue is offset in relation to the clamping edge of the window opening is.

Hierdurch ergibt sich, bei Einkerbung des Leiters, keine unzulässige Querschnittseinschnürung, so daß die geforderte Belastungsfähigkeit des Leiters voll erhalten bleibt.This results in no inadmissible cross-sectional constriction when the conductor is notched, so that the required load capacity of the conductor is fully maintained.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment of the invention is described below with reference to the accompanying Described drawings.

In den Figuren ist ein Zugfederanschluß gezeigt, der aus einer Zugfeder 1 und einer Stromschiene 4 besteht.In the figures, a tension spring connection is shown, which consists of a tension spring 1 and a Busbar 4 exists.

Die Zugfeder 1 ist schlaufenförmig gebogen und weist einen Klemmschenkel 2 sowie einen Anlageschenkel 3 auf. An diesem ist die Stromschiene 4 festgelegt, die im weiteren Verlauf einen im Klemmschenkel 2 vorgesehenen Fensterausschnitt 5 durchtritt.The tension spring 1 is loop-shaped and has a clamping leg 2 and a contact leg 3. On this, the busbar 4 is fixed, which in a window cut 5 provided in the clamping leg 2 passes.

Der sich unmittelbar an die untere Laibung 7 des Fensterausschnitts 5 anschließende Endbereich des Klemmschenkels 2 ist unter einem bestimmten Winkel gekröpft, wobei die Kröpfkante etwa mit der Laibung 7 zusammenfällt.The one immediately following the lower reveal 7 of the window section 5 End region of the clamping leg 2 is cranked at a certain angle, wherein the cranking edge coincides approximately with the reveal 7.

Durch die Kröpfung und der damit verbundenen Schrägstellung der Laibung 7 im Querschnitt wird eine Klemmkante 9 gebildet, durch die ein stiftförmiger Leiter 11, der wie aus der Figur 3 ersichtlich, durch den Fensterausschnitt führbar ist, an die Stromschiene 4 gepreßt wird.Due to the offset and the associated inclination of the reveal 7 in Cross section, a clamping edge 9 is formed through which a pin-shaped conductor 11, the as can be seen from FIG. 3, can be guided through the window cutout to the Busbar 4 is pressed.

Dabei gräbt sich die Klemmkante 9 in den Leiter 11 ein, wodurch dieser sicher gegen ein Herausziehen gehalten wird.In this case, the clamping edge 9 digs into the conductor 11, as a result of which it is securely opposed pulling out is held.

Die Stromschiene 4 weist eine ausgeprägte Zunge 6 auf, die sich unter einem bestimmten Winkel in Richtung des Endbereiches 8 des Klemmschenkels 2 neigt und deren freie Außenkante gleichfalls eine Klemmkante 10 bildet, die sich in Gebrauchsstellung, also bei eingeführtem Leiter 11, an der der Klemmkante 9 gegenüberliegenden Seite des Leiters 11 abstützt und sich dort aufgrund der durch den Klemmschenkel 2 aufgebrachten Federkraft, die den Leiter 11 gegen die Klemmkante 10 drückt, eingräbt.The busbar 4 has a pronounced tongue 6, which is under a certain Angle in the direction of the end region 8 of the clamping leg 2 inclines and whose free outer edge also forms a clamping edge 10, which is in the use position, that is, with the conductor 11 inserted, on the clamping edge 9 opposite Side of the conductor 11 is supported and there due to the clamping leg 2 applied spring force, which presses the conductor 11 against the clamping edge 10, digs in.

Als besonders vorteilhaft hinsichtlich der Vermeidung einer durch die Klemmkanten 9, 10 verursachten Kerbwirkung im Bereich des Leiters 11 und einer damit verbundenen Schwächung der Zugfestigkeit, hat sich eine versetzte Anordnung der Klemmkanten 9, 10 zueinander erwiesen.To be particularly advantageous with regard to avoiding the clamping edges 9, 10 caused a notch effect in the area of the conductor 11 and a related one Weakening the tensile strength, there has been an offset arrangement of the clamping edges 9, 10 to each other.

Der Kröpfwinkel des Endbereiches 8 sowie der Neigungswinkel der Zunge 6 sind den jeweiligen Erfordernissen, die abhängig vom Leiterquerschnitt sind, festzulegen.The crank angle of the end region 8 and the angle of inclination of the tongue 6 are the to determine the respective requirements, which depend on the conductor cross-section.

Zweckmäßig ist es, den Endbereich 8 in Einschieberichtung des Leiters 11 zu kröpfen, wodurch ein einfacheres Einschieben des Leiters 11 gewährleistet ist. In diese Richtung sollte auch die Schräge der Zunge 6 verlaufen. It is expedient to crank the end region 8 in the direction of insertion of the conductor 11, whereby an easier insertion of the conductor 11 is ensured. In these The slope of the tongue 6 should also run in the direction.
