Description

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

Ein derartiger Zugfederanschluß ist beispielsweise aus der EP 0 597 190 A bekannt.Such a tension spring connection is known for example from EP 0 597 190 A.

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

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

Es besteht darüber hinaus die weitere Forderung, 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. Dabei ist eine möglichst hohe Flächenpressung gewünscht, die jedoch nicht zu einer Beschädigung des Leiters führen darf.There is also a further requirement for 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 in Contact area is achieved. The highest possible surface pressure is desired which, however, must not damage the conductor.

Vor allem bei den immer kleiner werdenden Zugfeder-Anschlußelementen kann die Federkraft der Zugfeder nicht beliebig erhöht werden, da zur Erhöhung der Flächenpressung die Minimierung der Druckflächen als einzige Alternative verbleibt. Dabei ist allerdings zu beachten, daß, wie erwähnt, die Verbindung gasdicht sein soll.Especially with the increasingly smaller tension spring connection elements, the The spring force of the tension spring cannot be increased arbitrarily, since this increases the surface pressure minimizing the printing area remains as the only alternative. However, it should be noted that, as mentioned, the connection is gas-tight should.

Bei dem genannten bekannten Zugfederanschluß verläuft der Klemmschenkel der Zugfeder in einem leicht gekrümmten Verlauf, der sich über den Bereich des Fensterausschnittes und in gleicher Weise über den auf der Unterseite des Fensterausschnittes folgenden Endbereich erstreckt.In the known tension spring connection, the clamping leg runs Tension spring in a slightly curved course that extends over the area of the window opening and in the same way over that on the underside of the window opening extends the following end region.

Hierdurch steht eine Kante der unteren Laibung in einem kleinen Winkel zum eingesteckten Leiter, der allenfalls zu einer sehr kleinen Einkerbung des Leiters und damit nur zu einer geringen Klemmung des Leiters führt.As a result, an edge of the lower reveal is at a small angle to the inserted one Conductor, which leads to a very small indentation of the conductor and thus only leads to a slight clamping of the conductor.

Die DE-A 35 04 317 zeigt eine Klemme für elektrische Leiter mit einer Zugfeder, die in einer fensterartigen Unterbrechung eine Laibung hat, deren eine Kante ebenfalls in einem kleinen Winkel zum eingesteckten Leiter steht. Gegenüber dieser Kante ist eine gekrümmte Stütznase der Stromschiene angeordnet, um eine zusätzliche Sicherung zu gewährleisten.DE-A 35 04 317 shows a clamp for electrical conductors with a tension spring, which has a reveal in a window-like interruption, one edge of which is also is at a small angle to the inserted conductor. Opposite this Edge is a curved support tab of the busbar arranged to provide an additional To ensure backup.

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 und 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 the connection area between the tension spring and the busbar and the conductor unchanged spring force of the tension spring, even with the smallest tension spring connection elements, is as big as possible.

Die Aufgabe wird durch einen Zugfederanschluß mit den Merkmalen des kennzeichnenden Teiles des Anspruches 1 gelöst.The task is carried out by a tension spring connection with the characteristics of the characteristic Part of claim 1 solved.

Nunmehr erfolgt die Klemmung sowohl zwischen dem Klemmschenkel der Zugfeder und dem Leiter mittels einer sich deutlich in den Leiter eingrabenden Klemmkante und ferner zusätzlich die weitere sich ebenfalls eingrabende Klemmkante am freien Ende der Zunge der Stromschiene.Now the clamping takes place both between the clamping leg of the tension spring and the conductor by means of a clamping edge that clearly digs into the conductor and also additionally the further also digging-in clamping edge on free end of the tongue of the busbar.

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 the spring force of the tension spring remaining a multiple results in increased specific surface pressure.

Gemäß einer vorteilhaften Ausgestaltung ist die Klemmkante an der Zunge im Verhältnis zu der Klemmkante an der Laibung des Fensterausschnittes versetzt angeordnet. Daraus ergibt sich, daß bei Einkerbungen des Leiters sich keine unzulässigen Querschnittseinschnürungen ergeben, so daß die geforderte Belastungsfähigkeit des Leiters erhalten bleibt.According to an advantageous embodiment, the clamping edge on the tongue is in proportion offset to the clamping edge on the reveal of the window opening. The result of this is that there are no impermissible notches in the conductor Cross-sectional constrictions result, so that the required resilience of the leader remains.

Weiter vorteilhafte Ausführungen 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.

Es zeigen:

Show it:
Figure 1
a tension spring connection according to the invention in a partially sectioned side view;
Figure 2
a greatly enlarged partial section of the tension spring connection according to Figure 1;
Figure 3
a tension spring connection with mounted conductor in a perspective view.

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 is made.

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.

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 in terms of 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.
