Description
Die vorliegende Erfindung betrifft eine elektrische Anschlussklemme zum Anschließen wenigstens eines Leiters und insbesondere eine elektrische Anschlussklemme, welche sich auch zum Anschließen von Leitern mit großen Querschnitten eignet.The present invention relates to an electrical terminal for connecting at least one conductor and in particular an electrical terminal, which is also suitable for connecting conductors with large cross-sections.
Im Stand der Technik sind verschiedene Anschlussklemmen bekannt geworden, die sich auch zum Anschluss von Leitern großer Durchmesser eignen. So können beispielsweise Leiter mit großen Querschnitten an Schraubklemmen angeschlossen werden. Dabei wird der Leiter über eine Schraubverbindung an der elektrischen Anschlussklemme festgeklemmt. Nachteilig bei solchen Schraubklemmen ist es allerdings, dass ein einfaches Einschwenken des abisolierten Leiters von oben nicht ohne Weiteres möglich ist. Dies führt insbesondere bei großen und massiv ausgebildeten Leitern dazu, dass die Montage erheblich erschwert wird, da der Leiter umgebogen und axial von vorne in die Schraubklemme eingeführt werden muss, bevor der Leiter geklemmt werden kann.In the prior art various terminals have become known, which are also suitable for the connection of conductors of large diameter. For example, conductors with large cross-sections can be connected to screw terminals. The conductor is clamped to the electrical terminal via a screw connection. A disadvantage of such screw terminals, however, is that a simple pivoting of the stripped conductor from above is not readily possible. This leads in particular to large and solid conductors to the fact that the assembly is considerably more difficult because the conductor has to be bent over and inserted axially from the front into the screw terminal before the conductor can be clamped.
Leichter ist demgegenüber die Montage bei einer elektrischen Anschlussklemme, welche das Einschwenken eines anzuschließenden Leiters von oben erlaubt. Dabei kann der anzuschließende Leiter zuvor auf die passende Länge gekürzt werden und wird dann bei der Montage eingeschwenkt.In contrast, mounting is easier with an electrical connection terminal, which allows the pivoting of a conductor to be connected from above. In this case, the conductor to be connected can be shortened beforehand to the appropriate length and is then pivoted in during assembly.
Mit der
Vor dem bekannten Stand der Technik ist es deshalb die Aufgabe der vorliegenden Erfindung, eine elektrische Anschlussklemme zur Verfügung zu stellen, welche weniger kompliziert aufgebaute Einzelteile benötigt und einen ähnlich großen oder noch größeren Öffnungsbereich des Klemmhebels bei einer relativ geringen oder wohlmöglich geringeren Betätigungskraft zur Verfügung stellt.Prior to the known prior art, it is therefore the object of the present invention to provide an electrical connection terminal, which requires less complicated components and provides a similarly large or even larger opening area of the clamping lever at a relatively low or probably lower actuation force available ,
Diese Aufgabe wird durch eine elektrische Anschlussklemme mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Weiterbildungen der erfindungsgemäßen Anschlussklemme sind Gegenstand der Unteransprüche. Weitere Vorteile und Merkmale der vorliegenden Erfindung ergeben sich aus der allgemeinen Beschreibung und der Beschreibung des Ausführungsbeispiels.This object is achieved by an electrical terminal with the features of claim 1. Preferred developments of the terminal according to the invention are the subject of the dependent claims. Further advantages and features of the present invention will become apparent from the general description and the description of the embodiment.
Eine erfindungsgemäße elektrische Anschlussklemme dient zum elektrisch kontaktierenden Anschluss wenigstens eines Leiters eines an einer Halterung aufgenommenen Strombalkens. Es ist wenigstens eine Klemmfeder zum Aufbringen einer Klemmkraft vorgesehen. Ein schwenkbarer Klemmhebel dient zum Klemmen des Leiters. Dabei weist die Klemmfeder einen ersten Schenkel und wenigstens einen zweiten Schenkel auf. Die Klemmfeder ist mit dem ersten Schenkel gelenkig an den Klemmhebel gekoppelt. Die Klemmfeder ist mit dem zweiten Schenkel gelenkig an den Hilfshebel gekoppelt. Der Hilfshebel und der Klemmhebel sind verschwenkbar an der Halterung angeordnet.An electrical connection terminal according to the invention serves for the electrically contacting connection of at least one conductor of a current bar accommodated on a holder. At least one clamping spring is provided for applying a clamping force. A pivoting clamping lever is used to clamp the conductor. In this case, the clamping spring has a first leg and at least one second leg. The clamping spring is pivotally coupled to the first leg of the clamping lever. The Clamping spring is pivotally coupled to the second leg to the auxiliary lever. The auxiliary lever and the clamping lever are pivotally mounted on the holder.
Die erfindungsgemäße elektrische Anschlussklemme hat viele Vorteile, da sie einen Aufbau mit weniger Bauteilen und mit einfach aufgebauten Bauteilen erlaubt. Dadurch, dass ein Kraftschluss von der Halterung über den Klemmhebel, die Klemmfeder und den Hilfshebel erfolgt, kann mit relativ wenigen und konstruktiv einfachen Bauteilen einerseits sogar eine noch höhere Klemmkraft und andererseits sogar ein noch größerer Öffnungswinkel erreicht werden.The electrical terminal according to the invention has many advantages, since it allows a structure with fewer components and with simple components. The fact that a frictional connection of the holder via the clamping lever, the clamping spring and the auxiliary lever, can be achieved with relatively few and structurally simple components on the one hand even an even higher clamping force and on the other hand even an even larger opening angle.
Die Halterung kann auch als Klemmkörper bezeichnet werden und dient zu Aufnahme des Strombalkens und zur schwenkbaren Befestigung des Klemmhebels.The holder can also be referred to as a clamping body and serves to receive the current bar and the pivotal attachment of the clamping lever.
Die erfindungsgemäße elektrische Anschlussklemme stellt eine Kipp-Hebelklemme mit dynamischer Hebelübersetzung zur Verfügung.The electrical terminal according to the invention provides a tilting lever clamp with dynamic leverage available.
Vorzugsweise beträgt ein Öffnungswinkel zwischen dem Strombalken und der Klemmkante im Öffnungszustand wenigstens 45°. Insbesondere ist der Öffnungswinkel bzw. der maximale Öffnungswinkel größer 60° und vorzugsweise größer 75°. Öffnungswinkel von 90° und sogar mehr als 90° sind möglich und bevorzugt. Durch große Öffnungswinkel und einen nach oben hin frei zugänglichen Einschwenkbereich wird eine einfache Montage auch von Leitern mit großen Querschnitten ermöglicht, da die Leiter einfach von "oben", d.h. von der dem Strombalken gegenüberliegenden Seite in die Anschlussklemme eingeschwenkt werden können. Ein Umbiegen und Zurückschieben der in der Regel starren Leiter, um den Leiter dann von vorn in die Anschlussklemme einzuschieben, ist nicht nötig.Preferably, an opening angle between the current bar and the clamping edge in the open state is at least 45 °. In particular, the opening angle or the maximum opening angle is greater than 60 ° and preferably greater than 75 °. Opening angles of 90 ° and even more than 90 ° are possible and preferred. By large opening angle and a freely accessible upwardly swiveling range, an easy assembly of conductors with large cross sections is made possible, since the conductors can be easily swiveled into the terminal from "above", ie from the side opposite the current bar. A bending and pushing back which usually stare Ladder to then insert the conductor from the front into the terminal is not necessary.
Vorzugsweise sind an dem Klemmhebel eine erste Schwenkachse und wenigstens eine davon beabstandete zweite Schwenkachse vorgesehen. Insbesondere verfügt die Klemmfeder über eine erste Achsaufnahme und wenigstens eine davon beabstandete und insbesondere parallele zweite Achsaufnahme. Vorzugsweise ist der Hilfshebel mit einer ersten Dreheinheit und wenigstens einer davon beabstandeten und insbesondere parallelen zweiten Dreheinheit ausgerüstet. Das bedeutet, dass der Klemmhebel, die Klemmfeder und vorzugsweise der Hilfshebel jeweils über zwei voneinander entfernte separate und insbesondere parallele Gelenkstellen verfügen.Preferably, a first pivot axis and at least one second pivot axis spaced therefrom are provided on the clamping lever. In particular, the clamping spring has a first axle receptacle and at least one second axle receptacle spaced therefrom and in particular parallel. Preferably, the auxiliary lever is equipped with a first rotary unit and at least one spaced apart and in particular parallel second rotary unit. This means that the clamping lever, the clamping spring and preferably the auxiliary lever each have two mutually remote separate and in particular parallel joints.
Vorzugsweise ist der Klemmhebel über die erste Schwenkachse verschwenkbar an der Halterung befestigt. Insbesondere ist die erste Achsaufnahme der Klemmfeder an dem ersten Schenkel der Klemmfeder vorgesehen und es ist die zweite Achsaufnahme der Klemmfeder an dem zweiten Schenkel der Klemmfeder vorgesehen. Vorzugsweise ist die an dem ersten Schenkel angeordnete erste Achsaufnahme der Klemmfeder mit der zweiten Schwenkachse des Klemmhebels gekoppelt.Preferably, the clamping lever is pivotally mounted on the holder via the first pivot axis. In particular, the first axle receiving the clamping spring is provided on the first leg of the clamping spring and it is provided the second axle receiving the clamping spring on the second leg of the clamping spring. Preferably, the arranged on the first leg first axle receiving the clamping spring is coupled to the second pivot axis of the clamping lever.
Vorteilhafterweise weist die erste Dreheinheit des Hilfshebels eine Achse auf, die schwenkbar mit der zweiten Achsaufnahme an dem zweiten Schenkel der Klemmfeder verbunden ist. Insbesondere ist die zweite Dreheinheit des Hilfshebels schwenkbar an der Halterung angeordnet.Advantageously, the first rotary unit of the auxiliary lever has an axis which is pivotally connected to the second axle receptacle on the second leg of the clamping spring. In particular, the second rotary unit of the auxiliary lever is pivotally mounted on the holder.
Vorzugsweise weist die zweite Dreheinheit des Hilfshebels eine abgerundete Außenkontur auf, die an einer angepassten abgerundeten Ausnehmung der Halterung schwenkbar aufgenommen ist. Besonders bevorzugt weisen die Außenkontur und die Ausnehmung jeweils eine kreisrunde Form oder die Form eines Kreissegmentes auf. Insbesondere ist die zweite Dreheinheit des Hilfshebels schwenkbar oder drehbar an der abgerundeten Außenkontur der Halterung aufgenommen und vorzugsweise abgestützt.Preferably, the second rotary unit of the auxiliary lever has a rounded outer contour, which is pivotable on a matched rounded recess of the holder is included. Particularly preferably, the outer contour and the recess each have a circular shape or the shape of a circle segment. In particular, the second rotary unit of the auxiliary lever is pivotally or rotatably received on the rounded outer contour of the holder and preferably supported.
Es ist möglich und bevorzugt, dass die zweite Dreheinheit des Hilfshebels eine Öffnung umfasst, in die eine Führungsachse eingeführt ist. Dabei kann die zweite Dreheinheit über die Führungsachse an der Öffnung drehbar gelagert sein. Möglich ist es aber auch, dass die Führungsachse in der Öffnung nicht zur Übertragung von Kräften, sondern im Wesentlichen nur zur Führung dient. Die Führungsachse kann beispielsweise Teil des Gehäuses sein und beispielsweise aus einem Kunststoffzapfen bestehen, der in die Öffnung eingeschwenkt oder eingeklipst wird. Möglich ist es aber auch, dass die Führungsachse eine Achse an der Halterung ist oder aber separat in die Halterung eingeführt wird, um den Hilfshebel an der zweiten Dreheinheit schwenkbar aufzunehmen und/oder abzustützen.It is possible and preferable that the second rotation unit of the auxiliary lever includes an opening into which a guide shaft is inserted. In this case, the second rotary unit can be rotatably mounted on the guide axis at the opening. But it is also possible that the guide axis in the opening is not used for the transmission of forces, but essentially only for guidance. The guide axis may for example be part of the housing and, for example, consist of a plastic pin which is pivoted or clipped into the opening. However, it is also possible for the guide axis to be an axle on the holder or else to be introduced separately into the holder in order to pivotally receive and / or support the auxiliary lever on the second rotary unit.
In allen Ausgestaltungen ist es bevorzugt, dass die Klemmfeder Teil einer Betätigungseinheit ist. In einer einfachen Ausgestaltung besteht die Betätigungseinheit nur aus der Klemmfeder. Die Klemmfeder hat vorzugsweise eine Doppelfunktion: die Klemmfeder dient zum Aufbringen der Klemmkraft und gleichzeitig auch als Betätigungshebel.In all embodiments, it is preferred that the clamping spring is part of an actuating unit. In a simple embodiment, the actuator unit consists only of the clamping spring. The clamping spring preferably has a double function: the clamping spring serves to apply the clamping force and at the same time as an actuating lever.
An der Betätigungseinheit ist vorzugsweise wenigstens eine Werkzeugöffnung vorgesehen, um ein Werkzeug einzuführen und die elektrische Anschlussklemme zu betätigen, um beispielsweise einen elektrischen Leiter zu klemmen oder die Klemmung wieder aufzuheben.At least one tool opening is preferably provided on the actuating unit to introduce a tool and actuate the electrical connection terminal, for example to clamp an electrical conductor or to release the clamping.
Die Betätigungseinheit weist vorzugsweise eine Werkzeugaufnahme auf. Die Werkzeugaufnahme kann an einem Einsatzteil vorgesehen sein. Möglich und bevorzugt ist es, dass die Klemmfeder beispielsweise einen im Wesentlichen C-förmigen Querschnitt aufweist, und dass der Innenbereich des Querschnittes wenigstens teilweise durch das Einsatzteil ausgefüllt ist. An dem Einsatzteil kann die Werkzeugaufnahme vorgesehen sein, die beim Betätigen als Gegenlager dient, um die Betätigungskräfte zu übertragen.The actuating unit preferably has a tool holder. The tool holder may be provided on an insert part. It is possible and preferred that the clamping spring, for example, has a substantially C-shaped cross section, and that the inner region of the cross section is at least partially filled by the insert part. On the insert part, the tool holder may be provided which serves as an abutment when operating to transmit the actuating forces.
Das Einsatzteil kann beispielsweise aus Kunststoff bestehen. Möglich ist es aber auch, dass die Werkzeugaufnahme und/oder ein Gegenlager durch an der Klemmfeder umgebogene Laschen oder dergleichen zur Verfügung gestellt wird.The insert may for example consist of plastic. But it is also possible that the tool holder and / or an abutment is provided by bent over to the clamping spring tabs or the like.
Vorzugsweise ist ein Innendurchmesser der Werkzeugöffnung größer als ein Innendurchmesser der Werkzeugaufnahme. Dadurch ergeben sich viele Möglichkeiten, da für beispielsweise unterschiedliche Geometrien und Einsatzzwecke der elektrischen Anschlussklemme unterschiedliche Winkel der Werkzeugaufnahme an dem Einsatzteil vorgesehen werden können. Je nach Zugänglichkeit und geometrischen Verhältnissen kann die Ausrichtung der Werkzeugaufnahme an dem Einsatzteil unterschiedliche Winkel zur Oberfläche der Werkzeugöffnung an der Klemmfeder aufweisen. So kann durch unterschiedliche Einsatzteile eine unterschiedliche Konfiguration der gesamten Anschlussklemme ermöglicht werden. Dadurch kann für unterschiedliche Anschlussklemmen nur durch Austausch eines einzigen einfachen Bauteils eine erweiterte Anwendungsmöglichkeit erzielt werden, ohne den Vorratsbedarf an Teilen wesentlich zu erhöhen.Preferably, an inner diameter of the tool opening is larger than an inner diameter of the tool holder. This results in many possibilities, since different angles of the tool holder can be provided on the insert part, for example, different geometries and purposes of the electrical terminal. Depending on the accessibility and geometric conditions, the orientation of the tool holder on the insert part may have different angles to the surface of the tool opening on the clamping spring. Thus, a different configuration of the entire terminal can be made possible by different inserts. As a result, an extended application possibility can be achieved for different terminals only by replacing a single simple component, without significantly increasing the storage requirements for parts.
Die Werkzeugaufnahme erstreckt sich vorzugsweise quer zu dem Strombalken. Der Winkel zwischen der Werkzeugaufnahme und dem Strombalken kann im Öffnungszustand variieren und hängt vom vorgesehenen Einsatzzweck ab.The tool holder preferably extends transversely to the current bar. The angle between the tool holder and the current bar can vary in the open state and depends on the intended use.
Die Betätigungseinheit wirkt vorzugsweise über den Hilfshebel auf den Klemmhebel ein.The actuating unit preferably acts on the clamping lever via the auxiliary lever.
In einfachen Ausgestaltungen besteht die Betätigungseinheit praktisch nur aus der Klemmfeder, an der die Werkzeugöffnung vorgesehen ist. Möglich ist es auch, dass an der Klemmfeder ein Hebelfortsatz oder dergleichen vorgesehen ist, um die Anschlussklemme auch ohne zusätzliches Werkzeug betätigen zu können.In simple embodiments, the actuating unit practically consists only of the clamping spring on which the tool opening is provided. It is also possible that a lever extension or the like is provided on the clamping spring in order to operate the terminal without additional tool can.
In besonders bevorzugten Ausgestaltungen wirkt die Klemmfeder wenigstens im Klemmzustand als Zugfeder. Insbesondere ist die Klemmfeder wenigstens im Öffnungszustand im Wesentlichen entspannt. Besonders bevorzugt ist die Klemmfeder im Öffnungszustand vollständig entspannt. Unter dem Begriff "im Wesentlichen entspannt" wird im Sinne der vorliegenden Erfindung insbesondere eine wirksame Kraft verstanden, die kleiner als 10 % der maximal vorgesehenen Klemmkraft beträgt.In particularly preferred embodiments, the clamping spring acts at least in the clamping state as a tension spring. In particular, the clamping spring is at least substantially relaxed in the open state. Particularly preferably, the clamping spring is completely relaxed in the open state. For the purposes of the present invention, the term "substantially relaxed" means in particular an effective force which is less than 10% of the maximum intended clamping force.
In allen Ausgestaltungen ist es bevorzugt, dass sich der Klemmhebel in dem Klemmzustand hinter einem Totpunkt befindet. Dadurch wird zunächst ein Kraftaufwand benötigt, um den Klemmhebel aus dem Klemmzustand wieder in die Öffnungsstellung zu überführen. Das führt zu einer Selbstsicherung bzw. zu einer Selbsthemmung des Klemmzustands und erhöht die Sicherheit. Realisiert wird dies vorzugsweise dadurch, dass sich die als Zugfeder wirkende Klemmfeder vor dem Erreichen des Klemmzustands wieder etwas zusammenziehen kann, sodass die Spannung etwas nachlässt.In all embodiments, it is preferred that the clamping lever is in the clamping state behind a dead center. As a result, a force is first required to transfer the clamping lever from the clamping state back to the open position. This leads to a self-assurance or self-locking of the clamping state and increases security. This is preferably realized by the fact that as a tension spring acting clamping spring before reaching the clamping state can contract slightly again, so that the tension decreases slightly.
In allen Ausgestaltungen ist es bevorzugt, dass das Ende des ersten Schenkels und/oder das Ende des zweiten Schenkels der Klemmfeder jeweils umgebogen ist, um jeweils die erste und/oder die zweite Achsaufnahme zu bilden. Das ermöglicht eine einfache Fertigung der Klemmfeder und eine zuverlässige Funktion.In all embodiments, it is preferred that the end of the first leg and / or the end of the second leg of the clamping spring is respectively bent to form each of the first and / or the second axle receptacle. This allows easy production of the clamping spring and a reliable function.
In besonders bevorzugten Ausgestaltungen der Erfindung sind wenigstens die Halterung und der Klemmhebel und der Hilfshebel als gestanzte Biegeteile ausgeführt. Das ermöglicht eine besonders einfache und kostengünstige Fertigung und Montage.In particularly preferred embodiments of the invention, at least the holder and the clamping lever and the auxiliary lever are designed as stamped bent parts. This allows a particularly simple and cost-effective production and assembly.
Vorzugsweise ist an dem Strombalken wenigstens eine Nut zur Sicherung eines an dem Strombalken aufgenommenen und dort geklemmten Leiters vorgesehen. Besonders bevorzugt ist die Nut an dem Strombalken quer zur Einführöffnung vorgesehen und ist wenigstens etwa dort angeordnet, wo der Klemmhebel den Leiter gegen den Strombalken klemmt.Preferably, at least one groove for securing a conductor received on the current bar and clamped there is provided on the current bar. Particularly preferably, the groove is provided on the current bar transversely to the insertion opening and is arranged at least approximately where the clamping lever clamps the conductor against the current bar.
Vorzugsweise ist wenigstens ein Durchsteckschutz vorgesehen, welche ein Durchstecken eines aufgenommenen Leiters durch die Anschlussklemme verhindert. Beispielsweise kann ein solcher Durchsteckschutz aus einem in einer weiteren oder anderen Nut des Strombalkens aufgenommenen Teil bestehen, welches von außen durch entsprechende Löcher in der Halterung eingeführt wird und somit an der Halterung gesichert aufgenommen ist.Preferably, at least one push-through protection is provided, which prevents a passage of a recorded conductor through the terminal. For example, such a push-through protection consist of a recorded in another or other groove of the current bar part, which is inserted from the outside through corresponding holes in the holder and thus secured to the holder is added.
Die erfindungsgemäße elektrische Anschlussklemme ermöglicht die Aufbringung einer hohen Klemmkraft bei einem gleichzeitig möglichen großen Öffnungswinkel, der 60 oder 75° erreichen und überschreiten kann. Auch bei Leitern mit großen Querschnitten von 20 mm2, 25 mm2 oder 30 mm2 oder 35 mm2 wird nach einem erstmaligen Klemmen und der Entnahme eines solches Leiters eine Nullklemmung ermöglicht, bei der durch den Klemmhebel ein dünner Leiter mit Durchmessern von 1 mm, 0,5 mm oder weniger noch zuverlässig geklemmt werden kann.The electrical terminal according to the invention enables the application of a high clamping force at a simultaneously possible large opening angle, which can reach and exceed 60 or 75 °. Even with ladders with large cross-sections of 20 mm 2 , 25 mm 2 or 30 mm 2 or 35 mm 2 , a zero clamping is made possible after a first time terminals and the removal of such a conductor, in which by the clamping lever a thin conductor with diameters of 1 mm , 0.5 mm or less can still be reliably clamped.
Bei Überführen der elektrischen Anschlussklemme von dem Öffnungszustand in den Klemmzustand wird zunächst der Klemmhebel kraftlos oder doch nahezu kraftlos weitgehend geschlossen, bevor beim Weiterschwenken des Werkszeugs eine hohe Klemmkraft aufgebracht wird.When transferring the electrical terminal from the open state to the clamping state of the clamping lever is initially largely powerless or almost powerless largely closed before a high clamping force is applied during further pivoting of the tool.
Die elektrische Anschlussklemme ist insbesondere als eine Kniehebelklemme ausgebildet, die das einfache, schnelle und sichere Beschalten von verschiedensten Leiterquerschnitten ermöglicht. Das Prinzip dieser Kniehebelklemme basiert dabei auf einem Hebelmechanismus, an den ein Federmechanismus in Form einer Klemmfeder anschließt, um eine sehr große Kontaktnormalkraft auf den Leiter zu übertragen. Damit eine solch große Kraft erzeugt werden kann, ohne dass die Klemmfeder zu groß dimensioniert werden muss bzw. Schäden an der Klemmfeder auftreten, sollte die Federgeometrie einer bestimmten Formgebung entsprechen. Damit die Dimension der gesamten Kniehebelklemme im Rahmen einer im Schaltschrank eingesetzten Größe bleibt und vorzugsweise ferner der Materialeinsatz für die Klemmfeder gering ausfällt, wird besonders bevorzugt eine optimale Geometrie eingesetzt.The electrical terminal is designed in particular as a toggle clamp, which allows easy, fast and safe wiring of various conductor cross sections. The principle of this toggle clamp is based on a lever mechanism, which is followed by a spring mechanism in the form of a clamping spring to transmit a very large contact normal force on the conductor. In order for such a large force can be generated without the clamping spring must be oversized or damage to the clamping spring occur, the spring geometry should correspond to a specific shape. Thus, the dimension of the entire toggle clamp remains within a size used in the cabinet and preferably also the material used for the clamping spring low, an optimal geometry is particularly preferably used.
Vorteilhafter Weise weist die Klemmfeder wenigstens eine 1,5-fache S-Form auf. Somit wirkt die Klemmfeder wie zwei in Reihe geschaltete Federn mit erhöhter Federsteifigkeit bei gleichem Materialeinsatz und gleicher Baugröße. Die Klemmfeder besitzt an den Enden jeweils eine Achsaufnahme von z. B. der Art einer Öse für anzubindende Bauteile. Zwischen den Achsaufnahmen (Ösen) wird über die 1,5-fache S-Form eine Verbindung hergestellt. Die Biegeradien, sowohl der äußeren Biegung an den beiden Enden, als auch der mittleren Biegung richten sich nach dem Kraftverhältnis und der Federrate, die die Klemmfeder besitzen soll. Bei großer Federrate der Klemmfeder sollten die äußeren Radien kleiner und der mittlere Radius größer gestaltet werden. Für eine kleinere Federrate kann umgekehrt verfahren werden.Advantageously, the clamping spring has at least a 1.5-fold S-shape. Thus, the clamping spring acts as two series-connected springs with increased spring stiffness with the same material and the same size. The clamping spring has at the ends in each case an axle of z. B. the type of eyelet for components to be connected. A connection is made between the axle receptacles (eyelets) via the 1.5-fold S-shape. The bending radii, both the outer bend at the two ends, as well as the middle bend depend on the force ratio and the spring rate, which should have the clamping spring. At high spring rate of the clamping spring, the outer radius should be made smaller and the average radius larger. For a smaller spring rate can be reversed procedure.
Die Kontur kann natürlich auch aus weiteren Federn und aus mehr Radien als dem 1 ,5-fachen eines "S" bestehen und beliebig mehr S-artige-Formen aufweisen. Je mehr S-Formen vorhanden sind, desto steifer wird die Klemmfeder.The contour can of course also consist of other springs and more radii than 1.5 times a "S" and have any number of S-like shapes. The more S-shapes are present, the stiffer the clamping spring becomes.
Vorzugsweise weist die Klemmfeder wenigstens im Wesentlichen wenigstens eine 1,5-fache S-Form auf. Besonders bevorzugt weist die Klemmfeder eine 1,5-fache S-Form auf. Insbesondere weist die Klemmfeder in dem Bereich der 1,5-fachen S-Form einen Krümmungsabschnitt mit einem Außenradius (R2) und zwei Krümmungsabschnitte mit Innenradien (R1) auf, wobei die Krümmungen mit den Innenradien zu der Seite mit dem ersten Schenkel und dem zweiten Schenkel hin geöffnet sind und wobei der Krümmungsabschnitt mit dem Außenradius zu der anderen entgegengesetzten Seite hin geöffnet ist.Preferably, the clamping spring at least substantially at least a 1.5-fold S-shape. Particularly preferably, the clamping spring has a 1.5-fold S-shape. Specifically, in the region of 1.5 times S-shape, the clamp spring has a curvature portion with an outer radius (R2) and two curvature portions with inner radii (R1), with the curvatures having the inner radii to the side with the first leg and the second Leg are opened and wherein the curvature portion is opened with the outer radius to the other opposite side.
Dabei befinden sich die Abschnitte mit den Krümmungen mit Innenradien räumlich zwischen dem ersten Schenkel und dem zweiten Schenkel.In this case, the sections with the curvatures with inner radii are located spatially between the first leg and the second leg.
Besonders bevorzugt besteht die Klemmfeder aus dem ersten Schenkel und dem zweiten Schenkel und mehreren Krümmungsabschnitten dazwischen, nämlich vorzugsweise wenigstens zwei Krümmungsabschnitten mit Innenradien und einem dazwischen vorgesehenem Krümmungsabschnitt mit einem Außenradius.Particularly preferably, the clamping spring consists of the first leg and the second leg and a plurality of curvature sections therebetween, namely preferably at least two curvature sections with inner radii and a curvature section provided therebetween with an outer radius.
Besonders vorteilhaft ist es, wenn der Außenradius (R2) größer ist als die Innenradien (R1).
Weitere Vorteile und Merkmale der vorliegenden Erfindung ergeben sich aus dem Ausführungsbeispiel, welches im Folgenden mit Bezug auf die beiliegenden Figuren erläutert wird.It is particularly advantageous if the outer radius (R2) is greater than the inner radii (R1).
Further advantages and features of the present invention will become apparent from the embodiment, which will be explained below with reference to the accompanying figures.
