Description

Stand der TechnikState of the art

Die vorliegende Erfindung betrifft eine Federklemme, insbesondere eine Frontklemme, wobei ein Leiter in die Federklemme einsteckbar ist und ein Kontaktteil zum Verbinden des Leiters mit einer elektrischen Baugruppe kontaktiert.The present invention relates to a spring terminal, in particular a front terminal, wherein a conductor can be inserted into the spring terminal and a contact part for connecting the conductor contacted with an electrical assembly.

Es sind Federklemmen bekannt, bei denen ein Leiter mittels eines beweglichen Klemmkörpers an eine unbewegliche, stromführende Stromschiene geklemmt wird. In der Regel wird zum Verstellen des Klemmkörpers eine Schraube verwendet, mit der der Klemmkörper in seine Klemmposition verstellt wird.There are known spring terminals, in which a conductor is clamped by means of a movable clamping body to a stationary, current-carrying busbar. As a rule, a screw is used to adjust the clamping body, with which the clamping body is moved to its clamping position.

Eine solche Federklemme zeigt beispielsweise die Druckschrift EP 0 836 242 B1 , bei der ein elektrischer Leiter mit einem schwenkbar gelagerten Druckstück festklemmbar ist. Im Festklemmzustand des Druckstücks kontaktiert der Leiter eine Stromschiene. Für die Rückstellung des Druckstücks ist eine Feder vorgesehen.Such a spring clip shows, for example, the publication EP 0 836 242 B1 in which an electrical conductor with a pivotally mounted pressure piece can be clamped. In the clamping state of the pressure piece, the conductor contacts a busbar. For the provision of the pressure piece, a spring is provided.

Eine Federklemme nach dem Oberbegriff des Anspruchs 1 ist in US 5 494 456 A offenbart.A spring clip according to the preamble of claim 1 is in US 5 494 456 A disclosed.

Offenbarung der ErfindungDisclosure of the invention

Aufgabe der Erfindung ist es, eine sehr platzsparende und sehr kostengünstig herstellbare Federklemme zu schaffen, die für sehr viele Leiterquerschnitte verwendbar ist, und die gleichzeitig sehr leicht montierbar ist.The object of the invention is to provide a very space-saving and very inexpensive to produce spring clamp, which is suitable for many conductor cross sections, and at the same time is very easy to install.

Die Aufgabe wird gelöst mit einer Federklemme nach Anspruch 1.The object is achieved with a spring clip according to claim 1.

Da das Gehäuseteil erfindungsgemäß sowohl die Lagermittel als auch die Sicherungsmittel umfasst, ist die Federklemme mit sehr wenigen Bauteilen sehr kostengünstig herstellbar.Since the housing part according to the invention comprises both the bearing means and the securing means, the spring clip with very few components is very inexpensive to produce.

In einer bevorzugten Ausführungsform ist das Klemmmittel federnd so vorgesehen, dass es den Leiter in der eingesteckten Position hält. Da das Klemmmittel federnd vorgesehen ist, verstellt es sich beim Einstecken des Leiters selbsttätig. Dadurch ist die Federklemme für Leiter verschiedener Leiterquerschnitte in einem großen Leiterquerschnittsbereich verwendbar. Außerdem wirkt dadurch auf den eingesteckten Leiter eine Rückstellkraft des Klemmmittels, die in Richtung des Leiters wirkt und einem Herausziehen des Leiters entgegen der Einsteckrichtung entgegen wirkt.In a preferred embodiment, the clamping means is resiliently provided to hold the conductor in the inserted position. Since the clamping means is provided resiliently, it adjusts itself automatically when plugging in the conductor. This makes it possible to use the spring clip for conductors of different conductor cross sections in a large conductor cross section area. In addition, this acts on the inserted conductor, a restoring force of the clamping means, which acts in the direction of the conductor and counteracts pulling out of the conductor counter to the insertion.

Dabei ist das Klemmmittel bevorzugt sogar so vorgesehen, dass es den eingesteckten Leiter gegen Herausziehen entgegen der Einsteckrichtung sichert. Dadurch kann der eingesteckte Leiter nicht ohne Betätigungsmittel aus der Federklemme herausgezogen werden. Die Federklemme benötigt daher kein zusätzliches Mittel wie beispielsweise eine Verstellschraube, um das Klemmmittel so zu verstellen, dass es den Leiter sicher verklemmt.In this case, the clamping means is preferably even provided so that it secures the inserted conductor against pulling against the direction of insertion. As a result, the inserted conductor can not be pulled out of the spring clamp without actuating means. Therefore, the spring clip does not require any additional means such as an adjusting screw to adjust the clamping means so that it securely clamps the conductor.

Das Gehäuseteil umfasst weiterhin bevorzugt eine quer zu den Schenkelflächen angeordnete und diese verbindende Querfläche, so dass es im Wesentlichen u-förmig ausgebildet ist. Ein solches Gehäuseteil ist sehr schnell, kostengünstig und mit herkömmlichen Mitteln herstellbar, beispielsweise als Stanzbiegeteil. Es hat den Vorteil, dass es mit sehr geringen Herstellungstoleranzen und einer sehr großen Steifigkeit herstellbar ist.The housing part further preferably comprises a transversely arranged to the leg surfaces and connecting them transverse surface, so that it is formed substantially U-shaped. Such a housing part is very fast, inexpensive and can be produced by conventional means, for example as a stamped and bent part. It has the advantage that it can be produced with very low manufacturing tolerances and a very high rigidity.

Bevorzugt erstreckt sich die Kontaktschiene innerhalb des Gehäuseteils entlang der Querfläche, wobei das Klemmmittel ebenfalls bevorzugt zwischen den Schenkelflächen angeordnet ist. In dieser Anordnung sind der Kontakt der Kontaktschiene zum eingesteckten Leiter sowie der Klemmmechanismus durch das Gehäuse geschützt.Preferably, the contact rail extends within the housing part along the transverse surface, wherein the clamping means is also preferably arranged between the leg surfaces. In this arrangement, the Contact of the contact rail to the inserted conductor and the clamping mechanism protected by the housing.

Besonders bevorzugt ist das Klemmmittel symmetrisch zu einer sich im Wesentlichen parallel den Schenkelflächen erstreckenden Mittelebene angeordnet. Ebenfalls bevorzugt ist das Klemmmittel an den Schenkelflächen beidseitig der Mittelebene gelagert und/oder gesichert. Durch diese symmetrische Aufnahme des Klemmmittels im Gehäuseteil bleibt beim Einstecken des Leiters das Kräftegleichgewicht im Gehäuseteil erhalten.Particularly preferably, the clamping means is arranged symmetrically to a substantially parallel to the leg surfaces extending center plane. Also preferably, the clamping means is mounted on the leg surfaces on both sides of the median plane and / or secured. By this symmetrical recording of the clamping means in the housing part, the balance of forces in the housing part is maintained when inserting the conductor.

In einer bevorzugten Ausführungsform weisen die Schenkelflächen jeweils als Lagermittel ein Lagerfenster auf, wobei das Klemmmittel an seinem Lagerschenkel zwei Lagerkanten aufweist, die symmetrisch zur Mittelebene angeordnet sind, und mit denen das Klemmmittel in den Lagerfenstern gelagert ist. Im eingebauten Zustand des Klemmmittels erstrecken sich die Lagerkanten in die Lagerfenster. In einer ebenfalls bevorzugten Ausführungsform ist das Klemmmittel mit seinem Lagerschenkel auf Schenkelkanten der Schenkelflächen gelagert, die sich aus der Schenkelfläche in Richtung des Klemmmittels erstrecken. Im Vergleich der Ausführungsformen ist die Lagerung des Klemmmittels in den Lagerfenstern einerseits vorteilhafter, da bei dieser Ausführungsform die Beweglichkeit des Klemmmittels nicht durch vorstehende Schenkelkanten behindert wird. Außerdem kann sich das Klemmmittel in dieser Ausführungsform nicht Verschieben, sondern es ist sicher positioniert.In a preferred embodiment, the leg surfaces each have a bearing window as a bearing means, the clamping means having on its bearing leg two bearing edges, which are arranged symmetrically to the median plane, and with which the clamping means is mounted in the bearing windows. In the installed state of the clamping means, the bearing edges extend into the bearing window. In a likewise preferred embodiment, the clamping means is mounted with its bearing leg on leg edges of the leg surfaces, which extend from the leg surface in the direction of the clamping means. In comparison of the embodiments, the mounting of the clamping means in the bearing windows on the one hand more advantageous, since in this embodiment, the mobility of the clamping means is not hindered by protruding leg edges. In addition, the clamping means can not move in this embodiment, but it is securely positioned.

In der Ausführungsform der Erfindung weisen die Schenkelflächen jeweils als Sicherungsmittel zumindest einen Sicherungszahn auf, wobei das Klemmmittel zwei Sicherungskanten aufweist, die symmetrisch zur Mittelebene angeordnet sind. Bevorzugt wirkt der Sicherungszahn einer Schenkelfläche jeweils mit einer Sicherungskante des Klemmmittels zusammen. Um die Beweglichkeit des Klemmmittels nicht zu behindern, ist dabei eine Ausführungsform bevorzugt, bei der der Sicherungszahn in einem Sicherungsfenster der Schenkelfläche angeordnet ist, gegenüber einer weiteren Ausführungsform, bei der der Sicherungszahn sich von der Schenkelfläche ausgehend in Richtung des Klemmmittels erstreckt. Besonders bevorzugt sind im Sicherungsfenster mehrere Sicherungszähne vorgesehen, um eingesteckte Leiter verschiedener Leiterquerschnitte gegen Herausziehen zu sichern. Die Sicherungskanten sind bevorzugt an der Verbindungsstrebe angeordnet.In the embodiment of the invention, the leg surfaces each have at least one securing tooth as securing means, wherein the clamping means has two securing edges, which are arranged symmetrically to the median plane. Preferably, the securing tooth of a leg surface cooperates in each case with a securing edge of the clamping means. In order not to hinder the mobility of the clamping means, an embodiment is preferred in which the securing tooth is arranged in a securing window of the leg surface, compared to a further embodiment in which the securing tooth from the Leg surface extending starting in the direction of the clamping means. Particularly preferably, a plurality of securing teeth are provided in the securing window in order to secure inserted conductors of different conductor cross-sections against being pulled out. The securing edges are preferably arranged on the connecting strut.

Bevorzugt ist der eingesteckte Leiter zwischen dem Klemmmittel und der Kontaktschiene angeordnet, so dass das Klemmmittel unmittelbar auf den Leiter wirkt.Preferably, the inserted conductor is arranged between the clamping means and the contact rail, so that the clamping means acts directly on the conductor.

In einer weiteren bevorzugten Ausführungsform ist das Klemmmittel im Wesentlichen u-förmig und weist einen Lagerschenkel zum Lagern des Klemmmittels, einen Klemmschenkel zum Verklemmen des Leiters sowie eine die Schenkel des Klemmmittels verbindende Verbindungsstrebe auf, wobei die Schenkel jeweils in einem spitzen Winkel zur Verbindungsstrebe angeordnet sind. Beim Einstecken des Leiters verringert sich der spitze Winkel zwischen dem Klemmschenkel und der Verbindungsstrebe, wobei sich der spitze Winkel zwischen dem Lagerschenkel und der Verbindungsstrebe vergrößert. Dadurch weicht das Klemmmittel beim Einstecken des Leiters im Bereich der Ecke zwischen dem Klemmschenkel und der Verbindungsstrebe etwa kreisbogenförmig aus, wobei der Kreisbogen einen großen Kreisradius aufweist. Das Klemmmittel weist bevorzugt an seinem Klemmschenkel eine Klemmkante auf, die für einen formschlüssigen Kontakt mit dem Leiter vorgesehen ist. Die u-förmige Form des Klemmmittels ermöglicht, dass sich diese Klemmkante unabhängig vom Leiterquerschnitt beim Einstecken des Leiters nahezu horizontal bewegt und ihre Position am Leiter sich daher nahezu nicht in Abhängigkeit vom Leiterquerschnitt ändert.In a further preferred embodiment, the clamping means is substantially U-shaped and has a bearing leg for supporting the clamping means, a clamping leg for clamping the conductor and a connecting struts connecting the legs of the clamping means, wherein the legs are each arranged at an acute angle to the connecting strut , When inserting the conductor, the acute angle between the clamping leg and the connecting strut decreases, whereby the acute angle between the bearing leg and the connecting strut increases. As a result, the clamping means deviates during the insertion of the conductor in the region of the corner between the clamping leg and the connecting strut approximately circular arc, wherein the circular arc has a large radius of circle. The clamping means preferably has on its clamping leg on a clamping edge, which is provided for a positive contact with the conductor. The U-shaped form of the clamping means allows this clamping edge moves almost horizontally regardless of the conductor cross section when inserting the conductor and their position on the conductor therefore does not change almost as a function of the conductor cross section.

Um die Federklemme gegen das Eindringen von Staub und/oder Feuchtigkeit zu schützen und gleichzeitig elektrisch nach außen zu isolieren, umfasst die Federklemme bevorzugt weiterhin ein Isoliergehäuse. Im Isoliergehäuse sind bevorzugt das Gehäuseteil, das Klemmmittel und zumindest teilweise auch die Kontaktschiene angeordnet. Das Isoliergehäuse weist eine Einstecköffnung auf, durch die der Leiter in die Federklemme einsteckbar ist. Um einen in die Federklemme eingesteckten Leiter aus der Federklemme herausziehen zu können, ist sie weiterhin bevorzugt so ausgebildet, dass der Klemmschenkel bei eingestecktem Leiter mittels eines Betätigungsmittels, beispielsweise einem Schraubenzieher, betätigbar ist, so dass der Leiter der Federklemme entgegen der Einsteckrichtung entnehmbar ist.In order to protect the spring clip against the ingress of dust and / or moisture and at the same time to electrically isolate it to the outside, the spring clip preferably further comprises an insulating housing. In the insulating housing, the housing part, the clamping means and at least partially also the contact rail are preferably arranged. The insulating housing has a Insertion opening, through which the conductor is inserted into the spring clip. To be able to pull out a plugged into the spring clip ladder from the spring clip, it is further preferably designed so that the clamping leg with inserted conductor by means of an actuating means, such as a screwdriver, is actuated, so that the head of the spring clip opposite to the insertion can be removed.

Besonders bevorzugt ist die Federklemme als Frontklemme und/oder Reihenklemme ausgebildet.Particularly preferably, the spring clip is designed as a front terminal and / or terminal block.

Die erfindungsgemäße Federklemme hat den Vorteil, dass sie, obwohl sie sehr klein herstellbar ist, für Leiter unterschiedlicher Leiterquerschnitte verwendbar ist. Für den Kontakt sowie das Verklemmen des Leiters werden lediglich drei Bauteile benötigt, nämlich das Gehäuseteil, die Kontaktschiene und das Klemmmittel. Alle drei Bauteile sind als Stanzbiegeteile sehr kostengünstig herstellbar, und die Bauteile sind sehr leicht montierbar. Außerdem sind die Lagerkosten für die Federklemme aufgrund der geringen Bauteilezahl sehr gering. Schließlich ist die Federklemme auch sehr einfach bedienbar.The spring clip according to the invention has the advantage that, although it is very small to produce, it can be used for conductors of different conductor cross sections. For the contact and the jamming of the conductor only three components are needed, namely the housing part, the contact rail and the clamping means. All three components are produced very cost-effective as stamped and bent parts, and the components are very easy to install. In addition, the storage costs for the spring terminal due to the low number of components are very low. Finally, the spring clip is also very easy to use.

Im Folgenden wird die Erfindung anhand von Figuren beschrieben. Die Figuren sind lediglich beispielhaft und schränken den Erfindungsgedanken nicht ein.

Fig. 1 zeigt die erfindungsgemäße Federklemme ohne eingesteckten Leiter 3, und zwar in den Fig. 1 (a) und (c) in einer perspektivischen Ansicht, und in Fig. 1 (b) einen Schnitt durch die Federklemme 1 in einer Seitenansicht. Fig. 1 shows the spring clip according to the invention without inserted conductor 3, in the Fig. 1 (a) and (c) in a perspective view, and in Fig. 1 (b) a section through the spring clip 1 in a side view.

Die Federklemme 1 weist ein Gehäuseteil 5 auf, in dem eine Kontaktschiene 2 und ein Klemmmittel 4 angeordnet sind. Das Gehäuseteil 5 ist im Wesentlichen u-förmig ausgebildet und weist zwei im Wesentlichen parallel zueinander angeordnete Schenkelflächen 51 auf, in denen jeweils ein Sicherungsfenster 53 und als Lagermittel 54 ein Lagerfenster 54 vorgesehen sind. Im Folgenden werden die Begriffe Lagermittel 54 und Lagerfenster synonym verwendet. In dem Sicherungsfenster 53 sind als Sicherungsmittel 531 mehrere Sicherungszähne angeordnet. Im Folgenden werden die Begriffe Sicherungsmittel 531 und Sicherungszahn synonym verwendet. Die Schenkelflächen 51 sind mittels einer Querfläche 52 miteinander verbunden, die im Wesentlichen quer zu den Schenkelflächen 51 angeordnet ist.The spring clip 1 has a housing part 5, in which a contact rail 2 and a clamping means 4 are arranged. The housing part 5 is formed substantially U-shaped and has two substantially mutually parallel leg surfaces 51, in each of which a securing window 53 and a storage means 54, a bearing window 54 are provided. In the following, the terms storage means 54 and storage windows are used synonymously. In the securing window 53 531 several securing teeth are arranged as securing means. In the following, the terms securing means 531 and safety tooth are used interchangeably. The leg surfaces 51 are connected to each other by means of a transverse surface 52, which is arranged substantially transversely to the leg surfaces 51.

Die Kontaktschiene 2 erstreckt sich innerhalb des von dem Gehäuseteil 5 umbauten Raums entlang der Querfläche 52. Sie ragt an einem Kontaktende 201 aus dem Gehäuseteil 5 heraus und ist dort zu einer Zunge 21 umgebogen, an die eine elektrische Baugruppe 7, hier ein Leiter, der in Fig. 1 (c) beispielhaft und schematisch in gestrichelten Linien gezeigt ist, anschließbar ist. Außerdem ragt sie auch an einem Einsteckende 202 aus dem Gehäuseteil 5 heraus und ist dort so gebogen, dass ein Leiter 3 beim Einstecken in die Federklemme 1 (s. Fig. 1 (c)) in eine Einsteckrichtung 6 entlang der Kontaktschiene 2 geführt wird.The contact rail 2 extends within the space enclosed by the housing part 5 space along the transverse surface 52. It protrudes out of the housing part 5 at a contact end 201 and is bent there to a tongue 21, to which an electrical assembly 7, here a conductor, the in Fig. 1 (c) is shown by way of example and schematically in dashed lines, can be connected. In addition, it also protrudes out of the housing part 5 at a plug-in end 202 and is bent there such that a conductor 3 when plugged into the spring clip 1 (see FIG. Fig. 1 (c) ) is guided in a plug-in direction 6 along the contact rail 2.

Die Federklemme 1 umfasst weiterhin ein Isoliergehäuse 9, dass in Fig. 1 (a) schematisch gezeigt ist.The spring clip 1 further comprises an insulating housing 9, that in Fig. 1 (a) is shown schematically.

Fig. 2 zeigt die Federklemme der Fig. 1 mit eingestecktem Leiter 3, und zwar in Fig. 2 (a) in einer perspektivischen Ansicht, und in Fig. 2 (b) einen Schnitt durch die Federklemme 1 in einer Seitenansicht. Außerdem zeigt Fig. 3 in Fig. 3 (a) einen vergrößerten Ausschnitt aus der Fig. 2 (a) in einer anderen perspektivischen Ansicht und in Fig. 3 (b) den Schnitt A-A durch die Fig. 2 (a) in einer Seitenansicht. Fig. 2 shows the spring clip the Fig. 1 with plugged in conductor 3, in Fig. 2 (a) in a perspective view, and in Fig. 2 (b) a section through the spring clip 1 in a side view. Also shows Fig. 3 in Fig. 3 (a) an enlarged section of the Fig. 2 (a) in another perspective view and in Fig. 3 (b) the cut AA through the Fig. 2 (a) in a side view.

Das Klemmmittel 4 ist symmetrisch zu einer Mittelebene 8 (s. Fig. 3) im Gehäuseteil 5 gelagert, indem es zwei symmetrisch zur Mittelebene 8 angeordnete Lagerkanten 421 aufweist, die sich jeweils in die Lagerfenster 54 der Schenkelflächen 51 erstrecken. Die Lagerfenster 54 sind im Wesentlichen v-förmig vorgesehen, so dass das Klemmmittel 4 um ein spitzes Ende 541 des v-förmigen Lagerfensters 54 rotatorisch bewegbar ist. Andererseits erstreckt sich die Lagerkante 421 über eine gesamte Breite 542 des Lagerfensters 54, so dass ein Verschieben des Klemmmittels 4 quer zur Einsteckrichtung 6 nicht möglich ist.The clamping means 4 is symmetrical to a center plane 8 (s. Fig. 3 ) mounted in the housing part 5 by having two symmetrically arranged to the median plane 8 bearing edges 421, each extending into the bearing window 54 of the leg surfaces 51. The bearing windows 54 are provided substantially V-shaped, so that the clamping means 4 is rotatably movable about a pointed end 541 of the V-shaped bearing window 54. On the other hand, the bearing edge 421 extends over an entire width 542 of the bearing window 54, so that a displacement of the clamping means 4 transversely to the insertion direction 6 is not possible.

Das Klemmmittel 4 weist weiterhin zwei symmetrisch zur Mittelebene 8 angeordnete Sicherungskanten 411 auf, die sich jeweils in die Sicherungsfenster 53 der Schenkelflächen 51 erstrecken und beim Herausziehen des eingesteckten Leiters 3 entgegen die Einsteckrichtung 6 mit den Sicherungszähnen 531 zusammenwirken, die im Sicherungsfenster 53 angeordnet sind.The clamping means 4 further comprises two symmetrically arranged to the median plane 8 securing edges 411, each extending into the securing window 53 of the leg surfaces 51 and cooperate when pulling out the inserted conductor 3 against the insertion direction 6 with the securing teeth 531, which are arranged in the fuse window 53.

Fig. 4 zeigt ein Klemmmittel 4, und zwar in Fig. 4 (a) in einer perspektivischen und in Fig. 4 (b) in einer Seitenansicht. Fig. 4 shows a clamping means 4, in Fig. 4 (a) in a perspective and in Fig. 4 (b) in a side view.

Das Klemmmittel 4 ist im Wesentlichen u- förmig aufgebaut und weist einen Klemmschenkel 43, einen Lagerschenkel 42 sowie eine den Klemmschenkel 43 und den Lagerschenkel 42 verbindende Verbindungsstrebe 41 auf.The clamping means 4 is constructed substantially U-shaped and has a clamping leg 43, a bearing leg 42 and a connection leg 41 connecting the clamping leg 43 and the bearing leg 42.

Dabei sind sowohl der Klemmschenkel 43 als auch der Lagerschenkel 42 in einem spitzen Winkel 40 zur Verbindungsstrebe 41 angeordnet.In this case, both the clamping leg 43 and the bearing leg 42 are arranged at an acute angle 40 to the connecting strut 41.

Am Lagerschenkel 42 sind symmetrisch zur Mittelebene 8 (s. Fig. 3) die zwei Lagerkanten 421 angeordnet. Weiterhin sind an der Verbindungsstrebe 41 symmetrisch zur Mittelebene 8 die zwei Sicherungskanten 411 angeordnet. Schließlich weist der Klemmschenkel 43 eine Klemmkante 431 auf, mit der er an dem eingesteckten Leiter 3 formschlüssig anliegt und diesen verklemmt.On the bearing leg 42 are symmetrical to the median plane 8 (s. Fig. 3 ) the two bearing edges 421 arranged. Furthermore, symmetrically to the center plane 8, the two securing edges 411 are arranged on the connecting strut 41. Finally, the clamping leg 43 has a clamping edge 431 with which it rests positively against the inserted conductor 3 and jams it.

Beim Einstecken des Leiters 3 in die Federklemme 1 wird der spitze Winkel 40 zwischen dem Klemmschenkel 43 und der Verbindungsstrebe 41 verkleinert und der spitze Winkel 40 zwischen dem Lagerschenkel 42 und der Verbindungsstrebe 41 vergrößert, so dass das Klemmmittel 4 im Wesentlichen entlang eines Kreisbogens ausweicht und das Klemmmittel 4 gespannt wird. Dadurch wirkt eine Rückstellkraft des Klemmmittels 4 auf den eingesteckten Leiter 3, die den Leiter 3 in seiner Einsteckposition E hält.When inserting the conductor 3 in the spring clip 1, the acute angle 40 between the clamping leg 43 and the connecting strut 41 is reduced and the acute angle 40 between the bearing leg 42 and the connecting strut 41 increases, so that the clamping means 4 evades substantially along a circular arc and the clamping means 4 is tensioned. As a result, a restoring force of the clamping means 4 acts on the inserted conductor 3, which holds the conductor 3 in its insertion position E.

Da der Kreisbogen (nicht gezeigt) einen großen Radius (nicht gezeigt) aufweist, bewegt sich die Klemmkante 431 unabhängig vom Leiterquerschnitt der eingesteckten Leiter 3 nahezu geradlinig, so dass sich seine Position 10 relativ zur Höhe 11 (s. Fig. 2 (b)) des Gehäuseteils 5 in Abhängigkeit vom Leiterquerschnitt nahezu nicht ändert.Since the circular arc (not shown) has a large radius (not shown), the clamping edge 431 moves almost in a straight line, independently of the conductor cross section of the inserted conductors 3, so that its position 10 relative to the height 11 (see FIG. Fig. 2 (b) ) of the housing part 5 as a function of the conductor cross section almost does not change.

Beim Herausziehen des Leiters 3 entgegen der Einsteckrichtung 6 wird das Klemmmittel 4 angehoben, bis die Sicherungskante 411 an einem der Sicherungszähne 531 anliegt. Der Leiter 3 wird an der Klemmkante 431 verklemmt, so dass er gegen das Herausziehen gesichert ist. Mithilfe eines Betätigungsmittels (nicht gezeigt), mit dem der Klemmschenkel 43 so biegbar ist, dass sich der spitze Winkel 40 zwischen dem Klemmschenkel 43 und der Verbindungsstrebe 41 verringert, ist der Leiter 3 der Federklemme 1 entnehmbar.When pulling out the conductor 3 against the insertion direction 6, the clamping means 4 is raised until the securing edge 411 rests against one of the securing teeth 531. The conductor 3 is jammed at the clamping edge 431 so that it is secured against being pulled out. By means of an actuating means (not shown) with which the clamping leg 43 is bendable so that the acute angle 40 between the clamping leg 43 and the connecting strut 41 is reduced, the conductor 3 of the spring clip 1 can be removed.
