Description

Die Erfindung betrifft einen elektrischen Federkraftklemmanschluß gemäß den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to an electrical Spring terminal connection according to the features of the preamble of claim 1.

Ein wesentliches Gattungsmerkmal solcher Federkraftklemmanschlüsse ist ein viereckiger Materialdurchzug durch das aus einem flachen Material gefertigte Stromschienenstück, der als Leiterdurchstecköffnung dient und der einen in die Leiterdurchsteckrichtung sich erstreckenden Lochkragen besitzt, so daß zwischen der Lochkrageninnenwandfläche und einem in den Materialdurchzug sich hineinerstreckenden Ende einer Blattfeder eine Klemmstelle für einen elektrischen Leiter gebildet ist (siehe DE 28 25 291 C2).An essential generic feature of such Spring terminal connections is a quadrangular Material passage through the a track piece made of a flat material, as a Leiterdurchstecköffnung serves and one in the Leiterendurchsteckrichtung extending hole collar has, so that between the Lochkrageninnenwandfläche and one in the Material passage in hineinzerstreckenden End of a leaf spring a nip for an electrical conductor is formed (see DE 28 25 291 C2).

Solche Stromschienenstücke können mit einem, aber auch mit mehreren Materialdurchzügen versehen sein, die bevorzugt in einer Linie angeordnet sind, um eine möglichst schmale Bauform des Stromschienenstücks ( z. B. in Art eines ausgestanzten Materialstreifens) zu erhalten, wie dies z.B. für die Durchgangsstromschienen eng benachbarter Reihenklemmenanordnungen verlangt wird. Solche besonders schmalen Stromschienenstücke besitzen im Bereich der Materialdurchzüge lediglich schmale, in Stromschienenrichtung verlaufende Randstege, deren Stromleitungsquerschnitte im Regelfall nicht ausreichend sind. Dieser Nachteil wird durch die Lochkragen der Materialdurchzüge ausgeglichen, deren Lochkragenquerschnitte zugleich auch Stromleitungsquerschnitte sind, so daß in der Summe die Querschnitte der Randstege und die Lochkragenquerschnitte einen genügend großen Stromleitungsquerschnitt in Richtung des Stromschienenstücks zur Verfügung stellen.Such busbar pieces can with one, but also with several material passages Be provided in preference a line are arranged to one as possible Narrow design of the conductor rail piece (eg in the manner of a punched out Material strip), like this e.g. narrow for the through busbars adjacent terminal block assemblies is required. Such narrow ones Busbar pieces are in the range of Material passages only narrow, in Track direction running edge webs, whose power line cross sections in Usually not enough. This Disadvantage is the hole collar of material passages balanced, whose hole collar cross sections at the same time also power line cross sections are, so that in total the cross sections of the edge bars and the Lochkragenquerschnitte one enough large power line cross section in the direction of the conductor rail piece available put.

Jedoch, die bekannten Federkraftklemmanschlüsse dieser Art haben den Nachteil, daß die Stromübergangswerte zwischen der Lochkrageninnenwandfläche und dem geklemmten elektrischen Leiter nur schwach ausreichend sind. Praktische Versuche, dieses Problem durch eine Erhöhung der Klemmkräfte der Blattfeder zu lösen, waren unbefriedigend, da höhere Klemmkräfte die manuell aufzubringenden Einsteckkräfte für die Klemmung des elektrischen Leiters ungünstig beeinflussen.However, the known Federkraftklemmanschlüsse This type have the disadvantage that the current transfer values between the hole collar inner wall surface and the clamped electrical conductor weak enough are. Practical experiments, this problem by increasing the clamping forces of To solve leaf spring, were unsatisfactory, because higher clamping forces applied manually Insertion forces for the clamping of the electrical conductor unfavorably influence.

Die Aufgabe der Erfindung bestand deshalb darin, die gattungsgemäßen Vorteile eines Federkraftklemmanschlusses, der in seiner Stromschiene einen Materialdurchzug mit einem Lochkragen besitzt, beizubehalten, jedoch die Stromübergangswerte in der Klemmstelle zu verbessern, ohne dabei die Leitereinsteckkräfte zu erhöhen oder in anderer Weise den Leitereinsteckvorgang zu verschlechtern.The object of the invention therefore existed therein, the generic advantages of Spring terminal connection, which in its Busbar a material passage with owns a hole collar to maintain however, the current transfer values in the Improve nip without breaking the Increase conductor insertion forces or in otherwise, the ladder insertion process deteriorate.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Lochkrageninnenwandfläche, die mit dem Klemmschenkelende einer Blattfeder die Klemmstelle bildet, eine gegen den elektrischen Leiter vorstehende und quer zur Leiterdurchsteckrichtung sich erstreckende Querkante vorhanden ist und daß der Klemmschenkel der Blattfeder derart bemessen und geformt ist, daß die endseitige Klemmkante des Klemmschenkelendes in der Position der Klemmung des elektrischen Leiters in etwa der an der Lochkrageninnenwandfläche vorhandenen Querkante gegenüberliegt.This object is achieved according to the invention solved that at the hole collar inner wall surface, with the clamping leg end of a Leaf spring forms the nip, a projecting against the electrical conductor and across the Leiterdurchsteckrichtung itself extending transverse edge is present and that the clamping leg of the leaf spring in such a way dimensioned and shaped is that the end Clamping edge of the clamping leg end in the position of clamping of the electric Ladder approximately at the Lochkrageninnenwandfläche existing transverse edge opposite.

Dabei kann die Querkante in verschiedenen Anordnungspositionen entlang der in Leiterdurchsteckrichtung verlaufenden Erstreckung des Lochkragens angeordnet sein, jedoch sieht eine sehr vorteilhafte und fertigungstechnisch äußerst kostengünstige Ausführungsform der Erfindung vor, daß die Querkante durch die in Leiterdurchsteckrichtung untere Randkante des Lochkragens des Materialdurchzugs gebildet ist, die zu diesem Zweck gegen den zu klemmenden elektrischen Leiter vorgestellt ist, was entweder durch eine Neigungsanordnung des Stromschienenstücks insgesamt oder z. B. durch Anstauchen oder Drücken oder Formpressen des zugeordneten Lochkragenwandbereichs erfolgen kann.Here, the transverse edge in different Arrangement positions along the in Leiterdurchsteckrichtung extending extent the hole collar to be arranged, however looks a very beneficial and manufacturing technology extremely cost-effective Embodiment of the invention that the Transverse edge through the in Leiterdurchsteckrichtung lower edge of the hole collar the material passage is formed to this purpose against the to be clamped electrical conductor is presented what either by a tilt arrangement of the Busbar piece total or z. B. by upsetting or pressing or molding the associated hole collar wall area can be done.

Die anderen Lochkragenwandbereiche, die zur Bildung der Klemmstelle nichts beitragen, sind von dieser Maßnahme nicht betroffen, können jedoch gleichfalls verformt sein, wenn dies die fertigungstechnischen Arbeitsabläufe bei der Herstellung und Formung des Materialdurchzugs und des Lochkragens erleichtern sollte.The other hole collar wall areas used for Forming the nip does not contribute anything are not affected by this measure, however, they may also be deformed, if this is the production engineering Workflows in the production and Forming the material passage and the Hole collar should facilitate.

Die erfindungsgemäße Lösung ist für Federkraftklemmanschlüsse, die in ihrem Stromschienenstück einen Materialdurchzug mit einem Lochkragen aufweisen, neu und verbessert die Stromübergänge und die Kontaktsicherheit in der Klemmstelle ganz erheblich. Dies ergibt sich zum einen aus dem Vorteil der Bildung eines Kontaktpunktes, der sich als Kreuzungspunkt zwischen dem elektrischen Leiter und der vorstehenden Querkante an der Lochkrageninnenwandfläche darstellt und der geometrisch die Kontaktanlagefläche zwischen dem elektrischen Leiter und dem Lochkragen des Materialdurchzugs auf eine kleinere definierte Kontaktanlagefläche minimiert, in Kombination mit einer maximal möglichen Kontaktkraftaufbringung, die sich daraus ergibt, daß der Klemmschenkel der Klemmfeder derart bemessen und geformt ist, daß die endseitige Klemmkante des Klemmschenkelendes in der Position der Klemmung des elektrischen Leiters nahezu direkt auf die geometrisch minimierte Kontaktanlagefläche einwirkt, indem die Klemmkante des Klemmschenkelendes in etwa der an der Lochkrageninnenwandfläche gebildeten Querkante gegenüberliegt. Daraus resultiert eine hohe spezifische Flächenpressung in der Kontaktanlagefläche, die die Stromübergänge verbessert und zudem einen gasdichten Kontakt gewährleistet.The solution according to the invention is for spring-cage connections, in their track piece a material passage with have a hole collar, new and improved the power transitions and the contact safety quite considerably in the nip. This results for one from the Advantage of forming a contact point, which turns out to be a crossing point between the electrical conductor and the above Transverse edge at the hole collar inner wall surface represents and geometrically the contact surface between the electrical Ladder and the hole collar of the material passage to a smaller defined Contact contact area minimized, in combination with a maximum possible Contact force application resulting from it shows that the clamping leg of the clamping spring is sized and shaped so that the end-side clamping edge of the clamping leg end in the position of clamping of the electrical conductor almost directly on the geometrically minimized contact surface acts by the clamping edge of the Klemmschenkelendes approximately at the Lochkrageninnenwandfläche formed transverse edge opposite. This results in a high specific surface pressure in the contact surface, which improves the current transitions and also a gas-tight contact guaranteed.

Die Positionierung des Klemmschenkelendes der Blattfeder in etwa gegenüberliegend der Querkante an der Lochkrageninnenwandfläche hat den weiteren Vorteil, daß auf den geklemmten elektrischen Leiter keine aus der Klemmkraft der Blattfeder resultierenden Kippmomente ausgeübt werden.The positioning of the clamping leg end the leaf spring approximately opposite the Transverse edge at the hole collar inner wall surface has the further advantage that on the clamped no electrical conductor out of the Clamping force of the leaf spring resulting Tipping moments are exercised.

Ist in bevorzugter Weise die "vorstehende Querkante" an der Lochkrageninnenwandfläche durch die "vorgestellte untere Randkante" des Lochkragens des Materialdurchzugs gebildet, dann verlagert sich die Klemmstelle für den elektrischen Leiter maximal in die Tiefe des Materialdurchzugs hinein, woraus sich weitere erhebliche Vorteile ergeben.Is preferably the "above Transverse edge "at the hole collar inner wall surface through the "presented lower edge" the hole collar of the material passage formed, then the nip shifts for the electrical conductor maximum in the Depth of material passage in, from what There are further significant advantages.

So kann gemäß Anspruch 3 der Bereich der Lochkrageninnenwandfläche, der in Leitersteckrichtung der Klemmstelle vorgelagert ist, als relativ große und mit weichen Übergängen stoßfrei geformte (vorzugsweise plan geformte) Schrägfläche ausgebildet sein, die beim Einsteckvorgang das vorlaufende Ende des elektrischen Leiters weich und gleitend (d.h. ohne "hart" stoßende Übergänge) führt, so daß die Leitereinsteckkräfte verringert sind und ggf. vorhandene Oberflächenbeschichtungen, wie z.B. eine Zinnbeschichtung an der Lochkrageninnenwandfläche und im Bereich der Klemmstelle, gegen unerwünschte Abschabungen geschont werden.Thus, according to claim 3, the area the hole collar inner wall surface, which in Lead insertion direction upstream of the terminal point is, as relatively large and with soft transitions bump-shaped (preferably plan shaped) inclined surface formed be that during the insertion process the leading end of the electrical conductor soft and slippery (i.e., without "hard" pushing transitions), so that the Conductor insertion forces are reduced and possibly existing surface coatings, such as. a tin coating on the hole collar inner wall surface and in the field of Nip, against unwanted scraping be spared.

Mit dem Anspruch 5 soll die Aufgabe gelöst werden, für Federkraftklemmanschlüsse dieser Art eine Leiter-Vorfangtasche zu schaffen, damit auch mehrdrähtige elektrische Leiter problemlos gesteckt werden können. ohne daß sie aufspleißen und/oder sonstwie ausweichen können. Diese Aufgabe wird gemäß Anspruch 5 dadurch gelöst, daß sich bei unbelegter und geschlossener Klemmstelle ein endseitiges Teilstück des Klemmschenkels der Blattfeder innerhalb der Kontur des Materialdurchzugs befindet (d.h. in der Tiefe des Materialdurchzugs positioniert ist), und zwar mit einer Flächenerstreckung des Teilstücks, die gleich oder größer als der Nennquerschnitt des zu klemmenden Leiters ist derart, daß die ringförmig geschlossenen Lochkrageninnenwandflächen mit dem endseitigen Teilstück des Klemmschenkels eine allseits metallgefaßte Leiter-Vorfangtasche für das vorlaufende Ende des einzusteckenden elektrischen Leiters bilden.With the claim 5, the problem is solved for spring-cage connections this Kind of creating a ladder-catching bag thus also stranded electrical conductors can be plugged easily. without they splice and / or otherwise evade can. This object is according to claim 5 solved by that in unoccupied and closed nip an end-side Part of the clamping leg of the leaf spring within the contour of the material passage (i.e., in the depth of the material passage is positioned), with a surface extension of the section, the equal to or greater than the nominal cross section the conductor to be clamped is such that the annularly closed hole collar inner wall surfaces with the end portion of the Clamping leg a metalgefaßte on all sides Ladder front pocket for the leading end of the inserted electrical conductor form.

Für die geometrische Form der vorgenannten Leiter-Vorfangtasche ist es zweckmäßig, das endseitige Teilstück des Klemmschenkels der Blattfeder möglichst flachliegend innerhalb der Lochkragenkontur anzuordnen, so daß sich eine möglichst stumpfe Anlage der Stirnseite des Klemmschenkelendes gegen die Oberfläche des elektrischen Leiters ergibt, wodurch beim Auftreten von Leiterauszugskräften eine scharfkantige Leiterklemmung vermieden ist und auch empfindlichere feindrähtige elektrische Leiter beschädigungsfrei geklemmt werden können.For the geometric shape of the aforementioned Ladder front pocket, it is convenient, the end section of the clamping leg of the Leaf spring as flat as possible within to arrange the hole collar contour, so that a dull plant as possible Front side of the clamping leg end against the Surface of the electrical conductor, whereby upon occurrence of Leiterauszugskräften a sharp-edged ladder clamp is avoided and also more delicate finely stranded electrical conductor damage-free can be clamped.

Die Leiter-Vorfangtasche als solche bündelt mehrdrähtige Leiter und hat für alle Arten von elektrischen Leitern den Vorteil, daß bei einem Steckanschluß das vordere Ende des elektrischen Leiters zunächst kraftfrei in die Leiter-Vorfangtasche einzustecken ist und infolgedessen gegen Ausweichbewegungen fixiert ist, bevor mittels einer manuell auf den Leiter aufgebrachten Axialkraft das Öffnen der Klemmstelle eingeleitet wird.The ladder front pocket as such bundles stranded ladder and has for all kinds of electrical conductors the advantage that at a plug connection, the front end of the electrical conductor first force-free to be inserted into the ladder-catching bag is and as a result against evasive movements is fixed before by means of a manually applied to the conductor axial force the opening of the nip initiated becomes.

Mit dem Anspruch 6 soll die Aufgabe gelöst werden, bei Federkraftklemmanschlüssen dieser Art die Klemmstelle auch dann noch gut lösen zu können, wenn sich die Klemmstelle in der Tiefe des Materialdurchzugs befindet. Bei Federkraftklemmanschlüssen der gattungsgemäßen Art ist es immer ein Problem, zum Öffnen der Klemmstelle den Klemmschenkel der Blattfeder so weit entgegen seiner Federkraft zurückdrücken zu können, daß die Klemmstelle optimal, d.h. vollständig geöffnet ist. Insbesondere gilt das dann, wenn aufgrund einer kompakten Verdrahtungssituation die Notwendigkeit besteht, daß das Werkzeug (Schraubendreher) nur axial vorgeschoben werden kann, um die Klemmstelle zu öffnen.With the claim 6, the problem is solved be, with spring-cage connections this type of nip even then good to be able to solve when the nip in the depth of the material passage located. For spring-cage connections of the generic type, it is always a Problem, to open the nip the Clamping leg of the leaf spring so far push back against its spring force that the nip can be optimally, i. is completely open. In particular, applies that if, due to a compact Wiring situation the need exists that the tool (screwdriver) can only be advanced axially to the Open clamping point.

Dieses Problem wird gemäß Anspruch 6 dadurch gelöst, daß ein außerhalb der Kontur des Materialdurchzugs liegendes mittleres Teilstück des Klemmschenkels der Blattfeder eine Vorwölbung in Richtung der Federklemmkraft des Klemmschenkels aufweist derart, daß ein an dieser Vorwölbung und im wesentlichen senkrecht zur Oberfläche des Stromschienenstücks angesetztes Drückwerkzeug den Klemmschenkel bis in eine Position zurückdrückt, in der die Klemmstelle vollständig geöffnet ist.This problem is solved according to claim 6 solved that one outside the contour of material passage lying mid Part of the clamping leg of the leaf spring a protrusion in the direction of the spring clamping force of the clamping leg has such, that one at this bulge and essentially perpendicular to the surface of the busbar piece attached pressing tool the clamping leg to a position zurückpress, in which the nip completely is open.

Grundsätzlich ist darauf hinzuweisen, daß ein nach der Lehre der Erfindung konzipierter Federkraftklemmanschluß sowohl in der Bauart mit einer spiegelbildlich ausgeführten Blattfeder für zwei in einem Stromschienenstück benachbart angeordnete Materialdurchzüge verwirklicht werden kann (siehe hierzu die Bauart in DE 28 25 291 C2) als auch in einer Bauart mit einer Blattfeder, die einen Anlageoder Halteschenkel besitzt, der in beliebiger Weise an dem Stromschienenstück festgelegt sein kann (z.B. durch Vernieten oder Verpressen), oder es wird eine Bauart gewählt, bei der die Blattfeder gemäß Anspruch 4 der vorliegenden Anmeldung U-förmig gebogen ist und an ihrem dem Klemmschenkel entgegengesetzten Ende einen Anlageschenkel besitzt, der sich mit dem Klemmschenkel der Blattfeder in denselben Materialdurchzug des Stromschienenstücks hineinerstreckt und der an der Lochkrageninnenwandfläche anliegt, die der Lochkrageninnenwandfläche, die die Klemmstelle bildet, gegenüberliegt.Basically, it should be noted that a conceived according to the teachings of the invention Spring terminal connection both in of the type with a mirror image Leaf spring for two in a conductor rail piece adjacently arranged Material Durchzüge can be realized (See the type in DE 28 25 291 C2) and in a design with a leaf spring, a plant or Holding leg has, in any Way on the busbar piece fixed (e.g., by riveting or pressing), or it becomes a type chosen, in which the leaf spring according to Claim 4 of the present application U-shaped bent and at her the Clamping leg opposite end one Anlageschenkel owns, which with the Clamping leg of the leaf spring in the same Material passage of the conductor rail piece hineinerstreckt and at the hole collar inner wall surface is present, which the Lochkrageninnenwandfläche, the nip forms opposite.

Für die Stromschiene kann die Form eines schmalen Materialstreifens gewählt werden, der im Bereich der Materialdurchzüge Randstege 12 mit einer geringen Breite aufweist.Shown is (see Fig. 1) a busbar piece 10 with a square material passage 11, like this one more accurate the figure in Fig. 2a (longitudinal section) and Fig. 2b (top view) is removable. This in Fig. 2a and 2b illustrated piece of Bus bar 10 also shows that such material passages tight in any number positioned adjacent to each other in a row can be. For the busbar can be the shape of a narrow one Material strip to be selected in the Area of material passages edge bar 12 having a small width.

Der Materialdurchzug 11 besitzt einen von der Oberseite des Stromschienenstücks durchgezogenen, ringförmig geschlossenen Lochkragen 13 mit den Lochkrageninnenwandflächen 14 und 15. Die Übergänge von der Oberseite des Stromschienenstücks auf die Lochkrageninnenwandflächen können als Einführungsrundungen oder Einführungsschrägen 16 und 17 ausgebildet sein. The material passage 11 has one of the top of the busbar piece solid, annularly closed Hole collar 13 with the hole collar inner wall surfaces 14 and 15. The transitions of the Top of the busbar piece on the Inner hole wall panels can be used as Introductory roundings or introductory bevels 16 and 17 be formed.

In dem Materialdurchzug ist eine im wesentlichen U-förmig gebogene Blattfeder eingesetzt, die bei dem dargestellten Ausführungsbeispiel mit ihrem rückwärtigen Federbogen auf einem Kunststoffdorn 18 eines Isolierstoffgehäuses, in den solche Federkraftklemmanschlüsse eingebaut werden können, aufsitzt und dadurch zusätzlich lagefixiert ist. Die Blattfederbreite entspricht zumindest im Bereich des in dem Materialdurchzug sich hineinerstreckenden Anlageschenkels 19 und des in den Materialdurchzug eintauchenden Klemmschenkels 20 der Breite des viereckigen Durchzugs. Statt der zusätzlichen Lagefixierung durch den Kunststoffdorn 18 können z.B. auch andere Hilfsmittel, wie an der Oberseite des Stromschienenstücks anliegende Anschlagschultern des Anlageschenkels 19 und/oder z.B. ein Preßsitz des Anlageschenkels in dem Materialdurchzug zur zusätzlichen Lagefixierung der Blattfeder dienen. Jedoch kann in vielen Anwendungsfällen eine solche zusätzliche Lagefixierung der Blattfeder auch ganz entfallen, da die Vorspannung der U-förmigen Blattfeder auch eine Selbsthaltung der Blattfeder in dem Materialdurchzug gewährleistet.In the material passage is a substantially U-shaped bent leaf spring inserted, in the illustrated embodiment with her backward Spring bow on a plastic mandrel 18 an insulating material housing in which such Spring terminal connections are installed can, sit and thus additionally is fixed in position. The leaf spring width corresponds at least in the area of in the Material passage in hineinzerstreckenden Plant leg 19 and in the material passage immersed clamping leg 20 the width of the square passage. Instead of the additional position fixing by the Plastic mandrel 18 may e.g. others too Aids, as at the top of the Busbar piece fitting stop shoulders of the plant leg 19 and / or e.g. a press fit of the plant leg in the material passage for additional positional fixation serve the leaf spring. however can be such in many applications additional position fixation of the leaf spring also completely omitted, since the bias of the U-shaped leaf spring also a self-holding the leaf spring in the material passage guaranteed.

Die endseitige Klemmkante 21 des Klemmschenkels 20 liegt bei unbelegter und geschlossener Klemmstelle an der Lochkrageninnenwandfläche 15 an und ist somit in dem Materialdurchzug anschlag-fixiert gehalten.The terminal clamping edge 21 of the clamping leg 20 is empty and closed Clamping point at the hole collar inner wall surface 15 and is thus in the Material passage held stop-fixed.

Gemäß der Lehre der Erfindung ist an der Lochkrageninnenwandfläche 15 eine gegen den elektrischen Leiter, d.h. in Richtung des Zentrums des Materialdurchzugs vorstehende und quer zur Leiterdurchsteckrichtung durch den Materialdurchzug sich erstreckende Querkante ausgebildet, die bei dem dargestellten Ausführungsbeispiel durch die untere Randkante 22 des Lochkragens 13 gebildet ist, die zu diesem Zweck in Richtung des Zentrums des Materialdurchzugs vorgestellt ist.According to the teaching of the invention is at the Lochkrageninnenwandfläche 15 a against the electrical conductor, i. in the direction of Center of the material passage protruding and across the Leiterendurchsteckrichtung by the material passage extending Transverse edge formed in the illustrated Embodiment by the lower edge 22 of the hole collar 13 is formed is that towards that purpose in the direction of the center of material passage is.

Weiterhin ist gemäß der Lehre der Erfindung der Klemmschenkel 20 der Blattfeder derart bemessen und geformt, daß er in der Position der Klemmung des elektrischen Leiters 23 (siehe hierzu Fig. 5) maximal in die Tiefe des Materialdurchzugs eintaucht, wodurch seine endseitige Klemmkante 21 bei der Klemmung des elektrischen Leiters in etwa der unteren Randkante 22 des Lochkragens gegenüberliegt, so daß der elektrische Leiter 23 frei von Kippmomenten in der Klemmstelle 21/22 geklemmt ist.Furthermore, according to the teachings of the invention the clamping leg 20 of the leaf spring in such a way measured and shaped that he was in the Position of the clamp of the electric Conductor 23 (see FIG. 5) maximum in the depth of the material passage dips, whereby its end clamping edge 21 at the clamping of the electrical conductor in about the lower edge 22 of the hole collar opposite, so that the electrical Ladder 23 free from tilting moments in the clamping point 21/22 is clamped.

Das dargestellte Ausführungsbeispiel realisiert auch die Bildung einer sogenannten Leiter-Vorfangtasche 24 (siehe hierzu Fig. 3). Diese entsteht dadurch, daß sich bei unbelegter und geschlossener Klemmstelle das endseitige Teilstück 25 des Klemmschenkels 20 innerhalb der Kontur des Materialdurchzugs befindet, und zwar mit einer Flächenerstreckung, die gleich oder größer als der Nennquerschnitt des zu klemmenden Leiters 23 ist (vergl. Fig. 3). Die allseitig metallgefaßte Leiter-Vorfangtasche 24 erlaubt zunächst ein kraftfreies Einstecken des vorlaufenden Endes des elektrischen Leiters in die Vorfangtasche und verhindert sodann unerwünschte Ausweichbewegungen des vorderen Endes des Leiters, wenn auf diesen manuell eine Axialkraft zum Einstecken des Leiters in die Klemmstelle aufgebracht wird (sogenannter Steckanschluß).The illustrated embodiment implemented also the formation of a so-called Ladder leading pocket 24 (see Fig. 3). This arises from the fact that with blank and closed nip the end portion 25 of the Clamping leg 20 within the contour of the Material passage is located, with an areal extent equal to or greater than the nominal cross section of the clamping conductor 23 (see Fig. 3). The all-round metal-covered ladder front pocket 24 initially allows a force-free Inserting the leading end of the electrical conductor in the Vorfangtasche and then prevents unwanted Evasive movements of the front end of the Ladder, if manually on this one Axial force for inserting the conductor into the nip is applied (so-called Plug-in connection).

Den Funktionsablauf beim Einstecken des elektrischen Leiters in die Klemmstelle demonstrieren die Fig. 4 und 5, wobei die Formgebung der Lochkrageninnenwandfläche 15 als stoßfrei und plan ausgebildete Schrägfläche die für den Steckanschluß auf den elektrischen Leiter aufzubringende Axialkraft verringert.The functional sequence when inserting the electrical conductor in the nip demonstrate Figs. 4 and 5, wherein the Shape of the hole-collar inner wall surface 15 as bump-free and plan trained inclined surface the for the plug connection on the electrical conductor to be applied axial force reduced.

Das dargestellte Ausführungsbeispiel eines erfindungsgemäßen Federkraftklemmanschlusses berücksichtigt auch, daß gefordert ist, Federkraftklemmanschlüsse dieser Art ebenfalls für nicht-steckbare elektrische Leiter (z.B. für feindrähtige flexible Leiter) verwenden zu können und/ oder einen geklemmten elektrischen Leiter wieder aus der Klemmstelle lösen zu können. Zu diesem Zweck besitzt der Klemmschenkel 20 der Blattfeder eine Vorwölbung 26 (vergl. Fig. 5), die außerhalb der Kontur des Materialdurchzugs angeordnet ist derart, daß ein an dieser Vorwölbung und im wesentlichen senkrecht zur Oberseite des Stromschienenstücks angesetztes Drückwerkzeug 27 den Klemmschenkel bis in eine Position zurückdrückt, in der die Klemmstelle vollständig geöffnet ist (siehe Fig. 6).The illustrated embodiment of a spring terminal connection according to the invention also takes into account that demanded is spring-loaded terminals This type also for non-pluggable electrical conductors (for example for fine-wire flexible ladder) and / or a clamped electrical conductor release again from the terminal point can. For this purpose, the clamping leg has 20 of the leaf spring a protrusion 26 (see Fig. 5), the outside the contour of the material passage arranged is such that one at this protrusion and substantially perpendicular to the top of the busbar piece attached pressing tool 27 the clamping leg into a Pushes back position in which the nip is completely open (see Fig. 6).
