    • Zunächst sei auf Fig. 1 bis 6 Bezug genommen, die sich auf eine erste Ausführungsform der Erfindung beziehen. Fig. 3 zeigt eine Draufsicht auf ein ebenes Blechstanzteil 2, das zur Herstellung einer Stromschiene 4 einer im ganzen mit 6 bezeichneten Anschlußklemme dient. Wie Fig. 1 und 2 zeigen, wird hierfür ein Zwischenbereich 8 des Blechstanzteils 2 näherungsweise S-förmig abgekröpft, so daß ursprünglich in der Blechebene (Darstellungsebene) liegende Anschlußlaschen 10 senkrecht zu ihrer ursprünglichen Lage und senkrecht zur Erstreckungsebene der nunmehr gebildeten Stromschiene 4 liegen.Reference is first made to Figs. 1 to 6, which relate to a first embodiment relate to the invention. Fig. 3 shows a plan view of a flat sheet metal stamping 2, for the manufacture of a busbar 4 a designated as a whole with 6 Terminal serves. As shown in FIGS. 1 and 2, this is an intermediate area 8 of the sheet metal stamping part 2 bent approximately S-shaped, so that originally in the sheet metal plane (plane of representation) lying terminal lugs 10 vertically to its original position and perpendicular to the plane of extension of the now formed Busbar 4 are.

    Das Blechstanzteil 2 bzw. die daraus hergestellte Stromschiene 4 weisen anschließend an den Zwischenbereich 8 einen zentralen Abschnitt 12 auf, an den sich einerseits ein Sockelabschnitt 14 und andererseits zwei fingerartige, federnde Abschnitte anschließen, nämlich ein Rastabschnitt 16 und ein Verriegelungsabschnitt 18.The stamped sheet metal part 2 or the bus bar 4 made therefrom then have to the intermediate region 8 a central portion 12, on the one hand on the one hand a base portion 14 and on the other hand, two finger-like, resilient portions connect, namely a locking portion 16 and a locking portion 18th

    Sämtliche genannten Bereiche der Stromschiene bzw. des Blechstanzteils 2 sind wie erwähnt durch Stanzen aus einem ebenen Blechmaterial hergestellt. All said areas of the busbar or sheet metal stamping part 2 are like mentioned by punching made of a flat sheet material.

    Fig. 4 bis 6 erläutern die erfindungsgemäße Anschlußklemme 6 der ersten Ausführungsform, wobei in diesem Fall die Mittel zum Kontaktieren der anzuschließenden Leiter durch Schraubklemmelemente 22 gebildet sind, die auf die Anschlußlaschen 10 aufgeschoben sind. Klemmschrauben 24 dienen einer klemmenden Halterung eines eingeschobenen Leiters (nicht dargestellt) zwischen einer Bodenwand 26 eines Schraubklemmelements 22 und einer Anschlußlasche 10.4 to 6 illustrate the terminal 6 according to the invention of the first embodiment, in which case the means for contacting the one to be connected Ladder are formed by Schraubklemmelemente 22, which on the connecting lugs 10 are deferred. Clamping screws 24 serve for a clamping holder of a inserted conductor (not shown) between a bottom wall 26 of a Schraubklemmelements 22 and a connecting strap 10th

    Wie insbesondere Fig. 6 zeigt, ist die Breite b der Anschlußklemme 6, d.h. deren Abmessung in einer Anreihrichtung 30, aufgrund der gewählten Konstruktion relativ gering und beträgt in diesem Beispiel nur etwa das Vierfache der Blechstärke d des zur Herstellung der Stromschiene 4 verwendeten Blechmaterials.Referring particularly to Fig. 6, the width b of the terminal 6, i. their Dimension in a direction of arrangement 30, relative to the chosen construction low and in this example is only about four times the plate thickness d of for producing the busbar 4 used sheet metal material.

    Fig. 4 und 5 zeigen, wie die Anschlußklemme 6 an einer profilierten Schutzleiterschiene 32 gehalten ist. Die Schutzleiterschiene 32 hat ein topfförmiges bzw. im wesentlichen U-förmiges, mit abgewinkelten, flanschartigen Randabschnitten 34 versehenes Querschnittsprofil und stimmt mit ihrer Längsrichtung mit der bereits genannten Anreihrichtung 30 überein bzw. legt diese fest.Figs. 4 and 5 show how the terminal 6 on a profiled protective conductor rail 32 is held. The protective conductor rail 32 has a pot-shaped or substantially U-shaped, provided with angled, flange-like edge portions 34 Cross-sectional profile and agrees with its longitudinal direction with the aforementioned Arrangement 30 match or sets this.

    Der Sockelabschnitt 14 der Stromschiene 4 liegt mit zwei Kontaktvorsprüngen 20 (Fig. 1) jeweils gegen einen der Randabschnitte 34 an. Der Verriegelungsabschnitt 18 weist zwei parallele Stege 36 auf, die einenends mit dem zentralen Abschnitt 12 verbunden sind und anderenends ein Verriegelungsende 38 tragen, das einen der Randabschnitte 34 hintergreift und auf dem ein Anlagevorsprung 40 ausgebildet ist, der seitlich gegen den Randabschnitt 34 anliegt und dadurch die Position der Anschlußklemme 6 quer zur Anreihrichtung 30 festlegt. Dadurch, daß das Verriegelungsende 38 über zwei relativ schmale Stege 36 mit dem zentralen Abschnitt 12 verbunden ist, besteht eine gewisse Nachgiebigkeit bzw. Federelastizität zwischen dem Verriegelungsende 38 und dem zentralen Abschnitt 12, die sich durch Länge und Breite der Stege 36 einstellen bzw. vorgeben läßt. Ein Kontaktvorsprung 42 ist auf dem Verriegelungsende 38 ausgebildet, um die Flächenpressung an der Schutzleiterschiene 32 zu vergrößern und einen guten Kontakt herzustellen. The base portion 14 of the busbar 4 is located with two contact projections 20th (Fig. 1) in each case against one of the edge portions 34 at. The locking section 18 has two parallel webs 36, the one end with the central portion 12th are connected and the other end a locking end 38 wear, the one of the Engages behind edge portions 34 and on which a plant projection 40 is formed, the side bears against the edge portion 34 and thereby the position of the terminal 6 defines transversely to the direction of assembly 30. Characterized in that the locking end 38 via two relatively narrow webs 36 with the central portion 12th is connected, there is a certain flexibility or spring elasticity between the locking end 38 and the central portion 12 extending through length and adjust the width of the webs 36 or let pretend. A contact projection 42 is formed on the locking end 38 to the surface pressure on the protective conductor rail 32 to enlarge and make a good contact.

    Der Rastabschnitt 16 weist im Gegensatz zu dem Verriegelungsabschnitt 18 lediglich einen Steg 44 auf, so daß ein freier Endabschnitt 46 des Rastabschnitts 16 stärker federelastisch ist als das Verriegelungsende 38 des Verriegelungsabschnitts 18. Wie insbesondere Fig. 3 zeigt, weist der Rastabschnitt 16 an seinem freien Endabschnitt 46 einen Rastvorsprung 48 auf, der den anderen Randabschnitt 34 der Schutzleiterschiene 32 hintergreift. Damit auch in diesem Bereich eine möglichst große Kontaktkraft gegen den Kontaktvorsprung des Sockelabschnitts 14 erzielt wird, weist der Rastvorsprung 48 eine geneigt verlaufende Rastfläche 50 auf, die im aufgerasteten Zustand gegen den Randabschnitt 34 anliegt und in Zusammenwirken mit der Federkraft, die aufgrund der Ausbildung des Rastabschnitts 16 erzielt wird, ein verstärktes Anpressen des Randabschnitts gegen den Kontaktvorsprung bewirkt. Die Neigung der schrägen Rastfläche 50 ist in Fig. 3 mit einer gestrichelten Linie 52 angedeutet.The locking portion 16, in contrast to the locking portion 18 only a web 44, so that a free end portion 46 of the locking portion 16 is more resilient is as the locking end 38 of the locking portion 18. Like In particular Fig. 3 shows, the latching portion 16 at its free end portion 46, a locking projection 48, the other edge portion 34 of the protective conductor rail 32 takes hold. So that as much contact force as possible in this area is achieved against the contact projection of the base portion 14, the Detent projection 48 an inclined locking surface 50, which in the latched Condition rests against the edge portion 34 and in cooperation with the spring force, which is achieved due to the formation of the locking portion 16, a reinforced Pressing the edge portion against the contact projection causes. The inclination the oblique locking surface 50 is indicated in Fig. 3 with a dashed line 52.

    Ein Erfassungsabschnitt 54 am äußersten Ende des freien Endabschnitts 46 des Rastabschnitts 16 ermöglicht das Ansetzen eines Lösewerkzeugs, z.B. eines Schraubendrehers, um den Rastabschnitt 16 elastisch in Löserichtung 56 zu bewegen, so daß der Rastvorsprung 48 von dem Randabschnitt 34 gelöst wird und die Anschlußklemme 6 von der Schutzleiterschiene 32 abgenommen werden kann. Eine Aufsetzschräge 58 ermöglicht ein einfaches und werkzeugloses Aufsetzen bzw. Aufrasten der Anschlußklemme 6 auf die Schutzleiterschiene 32. Hierzu wird die Anschlußklemme 6 zunächst auf der Seite des Verriegelungsabschnitts 18 auf einen der Randabschnitte 34 aufgesetzt, wobei der Verriegelungsabschnitt 18 mit seinem Verriegelungsende 38 den Randabschnitt untergreift und mit dem Anlagevorsprung 40 gegen diesen zur Anlage gebracht wird. Danach wird die Anschlußklemme 6 um den Anlagebereich (Anlagevorsprung 40 bzw. Kontaktvorsprung 42) geschwenkt, bis die Aufsetzschräge 58 mit dem gegenüberliegenden Randabschnitt 34 in Berührung kommt, und weiter, wobei der Rastabschnitt 16 elastisch geöffnet wird, bis der Rastabschnitt 16 mit dem Rastvorsprung 48 zurückfedert und mit der Rastfläche 50 den Randabschnitt 34 hintergreift. In diesem Zustand ist die Anschlußklemme 6 sicher auf der Schutzleiterschiene 32 gehalten, bis sie durch Zurückbiegen des Rastabschnitts 16 gelöst wird. A detecting portion 54 at the extreme end of the free end portion 46 of the locking portion 16 allows the attachment of a release tool, e.g. a screwdriver, to move the latching portion 16 elastically in the release direction 56, so that the locking projection 48 is released from the edge portion 34 and the terminal 6 can be removed from the protective conductor rail 32. A touchdown slope 58 allows easy and tool-free placement or snapping the terminal 6 on the protective conductor rail 32. For this purpose, the terminal 6 first on the side of the locking portion 18 on one of Edge portions 34 mounted, wherein the locking portion 18 with its locking end 38 engages under the edge portion and with the investment projection 40th is brought against this to the plant. Thereafter, the terminal 6 to the Investment area (investment projection 40 and contact projection 42) pivoted until the Aufsetzschräge 58 with the opposite edge portion 34 in contact comes, and further, wherein the latching portion 16 is elastically opened until the Resting portion 16 springs back with the locking projection 48 and the locking surface 50th engages behind the edge portion 34. In this state, the terminal 6 is safe held on the protective conductor rail 32 until it by bending back of the locking portion 16 is solved.

    Der Verriegelungsabschnitt 18 und insbesondere dessen Kontaktvorsprung 42 ist so ausgebildet, daß sein Abstand, senkrecht zu einer die Kontaktvorsprünge 20 des Sokkelabschnitts 14 verbindenden Linie, im unbelasteten Zustand geringer ist als die Dickenabmessung des Randabschnitts 34, so daß im aufgerasteten Zustand der Verriegelungsabschnitt 18 federnd vorgespannt ist und eine gewünschte Kontaktkraft erzeugt. Entsprechendes gilt für die geneigte Rastfläche 50 des Rastabschnitts 16, so daß auch hier im aufgerasteten Zustand der Rastabschnitt 16 federnd gespannt ist und aufgrund der Neigung der Rastfläche 50 eine Kontaktkraft erzeugt.The locking portion 18 and in particular its contact projection 42 is so formed such that its distance, perpendicular to one of the contact projections 20 of the Sokkelabschnitts 14 connecting line, in the unloaded state is less than that Thickness of the edge portion 34, so that in the locked state of the locking portion 18 is resiliently biased and generates a desired contact force. The same applies to the inclined locking surface 50 of the locking portion 16, so that here in the latched state of the locking portion 16 is spring-loaded and due to the inclination of the locking surface 50 generates a contact force.

    Fig. 7 und 8 zeigen eine alternative Ausführungsform einer erfindungsgemäßen Anschlußklemme, die im ganzen mit 106 bezeichnet ist und mit einer ebenen Stromschiene 104 und zwei Federklemmelementen 110 versehen ist. Die Federklemmelemente 110 weisen jeweils einen Federschenkel 180 und einen Kontaktschenkel 182 auf und sind mit der Stromschiene 104 leitend verbunden. Die Kontaktschenkel 182 sind mittels Nietvorsprüngen 184, die an der Stromschiene 104 ausgebildet sind, leitend mit dieser verbunden.7 and 8 show an alternative embodiment of a terminal according to the invention, which is indicated as a whole by 106 and with a flat busbar 104 and two spring clips 110 is provided. The spring clamp elements 110 each have a spring leg 180 and a contact leg 182 on and are conductively connected to the busbar 104. The contact legs 182 are conductive by rivet projections 184 formed on the bus bar 104 connected to this.

    Wie bei der ersten Ausführungsform weist die Anschlußklemme 106 einen Rastabschnitt 116 und einen Verriegelungsabschnitt 118 auf, die ähnlich wie bei der ersten Ausführungsform ausgebildet sind und in entsprechender Weise die Schutzleiterschiene 32, die in Fig. 8 dargestellt ist, federnd hintergreifen.As in the first embodiment, the terminal 106 has a latching portion 116 and a locking portion 118 which are similar to the first Embodiment are formed and in a corresponding manner the protective conductor rail 32, which is shown in Fig. 8, resiliently engage behind.

    Fig. 9 und 10 erläutern eine weitere Ausführungsform einer erfindungsgemäßen Anschlußklemme 206, bei der ebenfalls Federklemmelemente 210 vorgesehen sind. Im Unterschied zur Stromschiene 104 der zweiten Ausführungsform gemäß Fig. 7 und 8 ist die Stromschiene 204 der dritten Ausführungsform nicht völlig eben, sondern weist zwei senkrecht zu einer Erstreckungsebene der Stromschiene (Darstellungsebene in Fig. 10) abgewinkelte Bereiche 270 auf, durch die Kontaktflächen 271 gebildet werden, die der Kontaktierung eines zwischen diesen und Federschenkeln 280 des Federklemmelements 210 eingeschobenen Leiters dienen. Der Kontaktschenkel 182 der zweiten Ausführungsform ist hier somit durch die abgewinkelten Bereiche 270 ersetzt. Figs. 9 and 10 illustrate another embodiment of a terminal according to the invention 206, in which also spring clamp elements 210 are provided. in the Difference to the busbar 104 of the second embodiment according to FIGS. 7 and 8 the bus bar 204 of the third embodiment is not completely flat, but has two perpendicular to an extension plane of the busbar (representation level in Fig. 10) angled regions 270, formed by the contact surfaces 271 are the contacting of a between these and spring legs 280 serve the Federerklemmelements 210 inserted conductor. The contact leg 182 of the second embodiment is thus here by the angled regions 270 replaced.

    Ein eine gekrümmte Anlagefläche 291 aufweisender Anschlag 290 ist einteilig zusammen mit der Stromschiene 204 ausgebildet, wodurch sich eine Vergrößerung der Federkonstanten des Federklemmelements 210 ergibt, da sich der Federschenkel 280 bei zunehmender Durchbiegung in Richtung auf den Anschlag 290 zunehmend an die Anlagefläche 291 anlegt, so daß eine Verkürzung der effektiven Länge des Schenkels und somit eine stärkere Federwirkung resultiert. A curved surface 291 having a stop 290 is integrally together formed with the bus bar 204, whereby an enlargement of the Spring constant of the spring clamp element 210 results because the spring leg 280 with increasing deflection in the direction of the stop 290 increasingly the contact surface 291 applies, so that a shortening of the effective length of the Leg and thus a stronger spring action results.
