Description

Die Erfindung betrifft eine elektrische Anschlussklemme.The invention relates to an electrical terminal.

Elektrische Anschlussklemmen sind in einer Vielzahl von Ausführungsformen bekannt. Die Anschlussklemmen können dabei beispielsweise zum Anschluss eines elektrischen Leiters an eine Leiterplatte als sogenannte Printklemme oder zur Verbindung mit einem weiteren Leiter als Reihenklemme ausgebildet sein.Electrical terminals are known in a variety of embodiments. The terminals may be formed as a so-called print terminal, for example, for connecting an electrical conductor to a printed circuit board or as a terminal block for connection to another conductor.

Als Klemmfedern werden sowohl schlaufenförmige Klemmfedern, sogenannte Zugfederklemmen, als auch U-förmige oder V-förmige Klemmfedern, sogenannte Schenkelfedern eingesetzt, in die starre Leiter oder mit einer Aderendhülse versehene Leiter direkt, d. h. ohne das die Klemmstelle vorher mit einem Werkzeug geöffnet werden muss, eingesteckt werden können. Bei den bekannten schlaufenförmigen Zugfedern wird - entsprechend ihrem Namen - der anzuschließende Leiter vom Klemmschenkel gegen eine Stromschiene gezogen. Im Unterschied dazu wird bei U-förmigen oder V-förmigen Klemmfedern der anzuschließende Leiter vom Klemmschenkel gegen die Stromschiene bzw. einen Bereich des Metallteils gedrückt.As clamping springs, both loop-shaped clamping springs, so-called tension spring terminals, as well as U-shaped or V-shaped clamping springs, so-called leg springs used in the rigid conductor or conductor with a ferrule provided directly, d. H. without the need to open the nip previously with a tool, can be plugged. In the known loop-shaped tension springs - according to their name - the conductor to be connected pulled by the clamping leg against a busbar. In contrast, in the case of U-shaped or V-shaped clamping springs, the conductor to be connected is pressed by the clamping leg against the busbar or a region of the metal part.

Zum Betätigen der Zugfederklemme benötigt man ein Betätigungswerkzeug, beispielsweise einen Schraubendreher, der zum Öffnen der Klemme in einen Betätigungsschacht eingeführt wird. Dabei spannt die Spitze des Schraubendrehers die Zugfeder, wodurch sich die Klemmstelle öffnet. Ein anzuschließender Leiter kann dann durch eine Ausnehmung in den Klemmschenkel eingeführt werden und wird nach dem Herausziehen des Betätigungswerkzeugs durch die Unterkante der Ausnehmung gegen eine mit der Zugfeder verbundene Stromschiene geklemmt. Dabei sind auch Anschlussklemmen bekannt, bei denen ein Betätigungselement im Gehäuse gelagert ist, um das Öffnen und Schließen der Zugfederklemme zu erleichtern. Das Betätigungselement kann in Form eines Hebels ausgebildet sein, welcher an einer Außenfläche des die Klemmfeder umgebenden Gehäuses angeordnet ist, so dass das Betätigungselement für einen Benutzer leicht zu erreichen und zu bedienen ist. Damit der Benutzer leicht erkennen kann, welche Anschlussklemme und damit welches Betätigungselement er bedienen soll, weist die Anschlussklemme auf der Oberfläche des Betätigungselements, welche von dem Gehäuse wegzeigt, üblicherweise eine Kennzeichnung bzw. Beschriftung auf. Die Kennzeichnung kann beispielsweise derart ausgestaltet sein, dass sie eine Zuordnung der Anschlussklemme zu den anzuklemmenden Leitern ermöglicht. Nachteilig hierbei ist jedoch, dass im geöffneten Zustand des Betätigungselements die Kennzeichnung für den Benutzer nicht lesbar ist, da das Bedienelement in diesem Zustand nach oben geschwenkt ist und die Oberfläche des Betätigungselements damit aus dem Sichtbereich des Benutzers herausgeschwenkt ist.To actuate the tension spring clamp requires an operating tool, such as a screwdriver, which is inserted to open the terminal in an operating shaft. The tip of the screwdriver tensions the tension spring, which opens the clamping point. A conductor to be connected can then be inserted through a recess in the clamping leg and is after pulling out of the actuating tool by the lower edge of the recess against one with the tension spring connected busbar clamped. In this case, terminals are known in which an actuating element is mounted in the housing in order to facilitate the opening and closing of the tension spring clamp. The actuator may be in the form of a lever which is disposed on an outer surface of the housing surrounding the clamping spring, so that the actuator is easy to reach and operate for a user. So that the user can easily recognize which terminal and thus which actuator he should operate, the terminal on the surface of the actuating element, which points away from the housing, usually a label or label on. The marking can for example be designed such that it allows an assignment of the terminal to the conductors to be clamped. The disadvantage here, however, that in the open state of the actuator, the label is unreadable for the user, since the control is pivoted in this state up and the surface of the actuator is thus pivoted out of the field of view of the user.

Aus DE 102 37 701 A1 ist ferner eine Verbindungsklemme, insbesondere für feindrähtige, elektrische Leiter bekannt. Die Verbindungsklemme weist eine Klemmfeder auf, die in einem Gehäuse mit Einführöffnungen angeordnet ist. Das Gehäuse weist dabei ein Gehäuseoberteil mit äußeren Verrastelementen auf. Ein Festklemmen eines Leiters kann dabei durch die Bewegung eines Betätigungshebels erfolgen.Out DE 102 37 701 A1 Furthermore, a connection terminal, in particular for fine-wire, electrical conductors is known. The connection terminal has a clamping spring, which is arranged in a housing with insertion openings. The housing has an upper housing part with outer latching elements. Clamping of a conductor can be done by the movement of an actuating lever.

Die Anschlussklemme umfasst ferner jeweils einem mit dem Federkraftklemmanschluss zusammenwirkendes Betätigungselement, das an einer Drehachse verschwenkbar in dem Isolierstoffgehäuse aufgenommen ist und das einen an dem Federkraftklemmanschluss anliegenden Betätigungsabschnitt hat, um den Federkraftklemmanschluss bei Schwenkbewegungen zu Öffnen beziehungsweise zu schließen. Im Bereich eines Betätigungsarms des Betätigungselements ist ferner ein Wandabschnitt vorgesehen, der als Beschriftungsfläche genutzt werden kann.Out EP 10 2007 050 936 A1 is a terminal for the electrical connection of conductors with an insulating material known.

Die Figuren zeigen eine elektrische Anschlussklemme 1, die zunächst aus einer Klemmfeder 2 und einem Metallteil 3 besteht. Sowohl die Klemmfeder 2 als auch das Metallteil 3 können dabei als einfache Stanz- und Biegeteile ausgebildet sein, wobei es jedoch nicht erforderlich ist, dass für die Klemmfeder 2 und das Metallteil 3 dieselben Materialien verwendet werden. Die Klemmfeder 2 und das Metallteil 3 sind gemeinsam in einem eine Leitereinführungsöffnung 4 aufweisenden Gehäuse 5 angeordnet, welches aus einem Isolierstoffmaterial, insbesondere aus Kunststoff besteht.The figures show an electrical connection terminal 1, which initially consists of a clamping spring 2 and a metal part 3. Both the clamping spring 2 and the metal part 3 may be formed as a simple stamped and bent parts, but it is not necessary that the same materials are used for the clamping spring 2 and the metal part 3. The clamping spring 2 and the metal part 3 are arranged together in a conductor insertion opening 4 having a housing 5, which consists of an insulating material, in particular of plastic.

Die Klemmfeder 2 weist einen Klemmschenkel 6, einen Betätigungsschenkel 7 und einen die beiden Schenkel 6, 7 miteinander verbindenden Rücken 8 auf, wobei der Klemmschenkel 6 mit dem Metallteil 3 eine Klemmstelle 9 für einen - lediglich in Fig. 3 gezeigten - anzuschließenden abisolierten Leiter 10 bilden. Im Gehäuse 5 ist ein Lagerzapfen 11 ausgebildet, an dem die Klemmfeder 2 derart verschwenkbar gelagert ist, dass die Klemmfeder 2 aus einer ersten (geöffneten) Position (Fig. 1 und 3) in eine zweite (geschlossene) Position (Fig. 2, 5 und 6) verschwenkt werden kann. In der ersten Position der Klemmfeder 2 kann ein durch die Leitereinführungsöffnung 4 eingeführter abisolierter elektrischer Leiter 10 in die Klemmstelle 9 eingeführt werden, ohne dass der Klemmschenkel 6 entgegen seiner Federkraft bzw. der Federkraft der Klemmfeder 2 ausgelenkt werden muss. In der zweiten Position der Klemmfeder 2 wird der elektrische Leiter 10 zwischen dem Ende des Klemmschenkels 6 und dem Metallteil 3 elektrisch leitend geklemmt, wobei der Klemmschenkel 6 aus seinem Ruhezustand ausgelenkt ist.The clamping spring 2 has a clamping leg 6, an actuating leg 7 and the two legs 6, 7 interconnecting back 8, wherein the clamping leg 6 with the metal part 3 a nip 9 for a - only in Fig. 3 shown - to be connected stripped conductor 10. In the housing 5, a bearing pin 11 is formed, on which the clamping spring 2 is mounted pivotably such that the clamping spring 2 from a first (open) position ( Fig. 1 and 3 ) to a second (closed) position ( Fig. 2 . 5 and 6 ) pivots can be. In the first position of the clamping spring 2, a stripped electrical conductor 10 introduced through the conductor insertion opening 4 can be introduced into the clamping point 9 without the clamping leg 6 having to be deflected against its spring force or the spring force of the clamping spring 2. In the second position of the clamping spring 2, the electrical conductor 10 is electrically conductively clamped between the end of the clamping leg 6 and the metal part 3, wherein the clamping leg 6 is deflected from its rest state.

Die Betätigung der elektrischen Anschlussklemme 1 erfolgt dadurch besonders benutzerfreundlich, dass in dem Gehäuse 5 ein Betätigungselement 12 an einem zweiten Leiterzapfen 13 schwenkbar gelagert ist. Wird das Betätigungselement 12 aus der in Fig. 1 gezeigten ersten (geöffneten) Position in seine in Fig. 2 gezeigte zweite (geschlossene) Position verschwenkt, so wird die Klemmfeder 2 durch das Verschwenken des Betätigungselements 12 aus ihrer ersten Position in ihre zweite Position verschwenkt. Die elektrische Anschlussklemme 1 kann somit durch ein Herunterdrücken des schwenkbar gelagerten Betätigungselements 12 geschlossen sowie durch ein Verschwenken des Betätigungselements 12 in die entgegengesetzte Richtung - wieder - geöffnet werden. Die Figuren 3 bis 5 zeigen dabei den Schließvorgang der Klemmfeder 2 zu drei aufeinander folgenden Zeitpunkten während die Figuren 6 und 7 den Öffnungsvorgang zu zwei Zeitpunkten zeigen. Bei der in den Figuren 1 bis 7 dargestellten Anordnung und Orientierung der elektrischen Anschlussklemme 1 muss das Betätigungselement 12 zum Schließen im Uhrzeigersinn und zum Öffnen entgegen dem Uhrzeigersinn verschwenkt werden, d. h. das Betätigungselement 12 wird zum Schließen herunter gedrückt und zum Öffnen nach oben verschwenkt. Um das Öffnen und Schließen des Betätigungselements 12 für einen Benutzer zu erleichtern, weist das Betätigungselement 12 einen Griff 27 auf, welcher in Form eines Hebels ausgebildet ist.The actuation of the electrical connection terminal 1 is effected particularly user-friendly, that in the housing 5, an actuating element 12 is pivotally mounted on a second conductor pin 13. If the actuator 12 from the in Fig. 1 shown first (opened) position in his in Fig. 2 shown pivoted second (closed) position, the clamping spring 2 is pivoted by the pivoting of the actuating element 12 from its first position to its second position. The electrical connection terminal 1 can thus be closed by a depression of the pivotally mounted actuating element 12 and by a pivoting of the actuating element 12 in the opposite direction - again - be opened. The FIGS. 3 to 5 show the closing operation of the clamping spring 2 at three consecutive times during the FIGS. 6 and 7 show the opening process at two times. In the in the FIGS. 1 to 7 illustrated arrangement and orientation of the electrical terminal 1, the actuator 12 must be pivoted to close in a clockwise direction and to open counterclockwise, ie, the actuator 12 is pressed down to close and pivoted upwards to open. To facilitate the opening and closing of the actuator 12 for a user, the actuator 12 has a handle 27 which is in the form of a lever.

Zur Markierung bzw. Kennzeichnung der Anschlussklemme 1 ist eine Beschriftungsfläche 28 vorgesehen, welche derart angeordnet ist, dass die Beschriftungsfläche 28 für einen Benutzer zu jeder Zeit sichtbar ist. Die Beschriftungsfläche 28 ist vorzugsweise eine an der Anschlussklemme 1 angeordnete plane Fläche welche mittels einer Farbcodierung oder eines oder mehrerer Zeichen oder Symbolen unmittelbar, d. h. direkt auf der Oberfläche der Beschriftungsfläche, beschriftet werden kann. Diese Beschriftungsfläche 28 ist derart an der Anschlussklemme 1 angeordnet, dass die Beschriftungsfläche 28 und damit die Beschriftung 29 für einen Benutzer zu jeder Zeit sichtbar und erkennbar ist. In Fig. 1 und 2 ist exemplarisch eine derartige Beschriftung 29 auf der Beschriftungsfläche 28 gezeigt.For marking or marking of the terminal 1, a labeling surface 28 is provided, which is arranged such that the labeling surface 28 is visible to a user at any time. The inscription surface 28 is preferably a plane surface arranged on the connection terminal 1, which can be inscribed directly by means of color coding or one or more characters or symbols, ie directly on the surface of the inscription surface. This labeling surface 28 is arranged on the connecting terminal 1 such that the inscription surface 28 and thus the inscription 29 is visible and recognizable to a user at all times. In Fig. 1 and 2 By way of example, such a lettering 29 is shown on the inscription surface 28.

Die Beschriftungsfläche 28 ist an einer Außenfläche des Gehäuses 5 angeordnet. Die Außenfläche des Gehäuses 5 ist die Fläche des Gehäuses 5, welche von der in dem Gehäuse 5 angeordneten Klemmfeder 2 wegzeigt. Die Beschriftungsfläche 28 ist dabei an der Außenfläche des Gehäuses 5 angeordnet, an welcher im geschlossenen Zustand des Betätigungselements 12 der Griff 27 des Betätigungselements 12 anliegt. Das Betätigungselement 12 weist ferner eine Aussparung 30 auf, welcher derart ausgebildet ist, dass im geschlossenen Zustand des Betätigungselements 12 die Beschriftungsfläche 28 in die Aussparung 30 eingreift. Die Aussparung 30 ist vorzugsweise als Durchgangsöffnung ausgebildet und ist an dem Griff 27 des Betätigungselements 12 angeordnet, welcher an der Außenfläche des Gehäuses 5 anliegt. Die Aussparung 30 weist vorzugsweise die Form der Beschriftungsfläche 28 auf, so dass die Beschriftungsfläche 28 passgenau in die Aussparung 30 eingreifen kann. Somit ist die Beschriftungsfläche 28 für den Benutzer jederzeit sichtbar, sowohl wenn das Betätigungselement 12 geschlossen ist als auch wenn das Betätigungselement 12 geöffnet ist. Im Bereich der Beschriftungsfläche 28 ist das Gehäuse 5 vorzugsweise in Form einer Rastnase ausgebildet, so dass die Rastnase in die Aussparung 30 des Griffs 27 des Betätigungselements 12 eingreifen kann. Die Beschriftungsfläche 28 ist mittels Tintenstrahldrucker, Plotter oder Thermotransverfahren beschriftbar. Damit kann die Beschriftung 29 der Beschriftungsfläche 28 einfach und schnell erfolgen.The labeling surface 28 is arranged on an outer surface of the housing 5. The outer surface of the housing 5 is the surface of the housing 5, which faces away from the arranged in the housing 5 clamping spring 2. The labeling surface 28 is arranged on the outer surface of the housing 5, on which in the closed state of the actuating element 12, the handle 27 of the actuating element 12 is applied. The actuating element 12 further has a recess 30, which is designed such that in the closed state of the actuating element 12, the inscription surface 28 engages in the recess 30. The recess 30 is preferably formed as a passage opening and is arranged on the handle 27 of the actuating element 12, which on the outer surface of the housing 5 rests. The recess 30 preferably has the shape of the inscription surface 28, so that the inscription surface 28 can fit precisely into the recess 30. Thus, the labeling surface 28 is visible to the user at all times, both when the actuator 12 is closed and when the actuator 12 is open. In the area of the labeling surface 28, the housing 5 is preferably designed in the form of a latching nose, so that the latching lug can engage in the recess 30 of the handle 27 of the actuating element 12. The labeling surface 28 can be labeled by means of an inkjet printer, plotter or thermotrans process. Thus, the label 29 of the inscription surface 28 can be done easily and quickly.

Wie insbesondere aus den Fig. 2 und 5 ersichtlich ist, ist die Klemmfeder 2 in ihrer zweiten Position verriegelt, so dass die Klemmfeder 2 nach dem Anschließen eines elektrischen Leiters 10 aufgrund ihrer schwenkbaren Anordnung und aufgrund ihrer Federkraft nicht wieder in Richtung der ersten Position zurückschwenkt. Dazu weist der Betätigungsschenkel 7 der Klemmfeder 2 an seinem dem Klemmschenkel 6 fernen Ende einen in Richtung des Klemmschenkels 6 abgebogenen Halteabschnitt 14 auf. Korrespondierend dazu weist auch das Metallteil 3 neben einem Klemmabschnitt 15 einen davon in Richtung des Betätigungsschenkels 7 abgebogenen Halteabschnitt 16 auf. Bei dem in den Figuren 1 bis 7 dargestellten bevorzugten Ausführungsbeispiel der Anschlussklemme 1 wird die Verrastung zwischen dem Halteabschnitt 14 des Betätigungsschenkels 7 und dem Halteabschnitt 16 des Metallteils 3 dadurch realisiert, dass an dem Halteabschnitt 14 des Betätigungsschenkels 7 zwei jeweils seitlich nach außen vorstehende Vorsprünge 17 ausgebildet sind und der Halteabschnitt 16 des Metallteils 3 zwei separate abgebogene Rastenden 18 aufweist. Im verrasteten Zustand der Klemmfeder 2 gemäß Fig. 2 sind dabei die Vorsprünge 17 unter den Rastenden 18 eingerastet, so dass die Klemmfeder 2 in ihrer geschlossenen Position gehalten wird und nicht in ihre geöffnete Position zurückschwenken kann.As in particular from the Fig. 2 and 5 It can be seen, the clamping spring 2 is locked in its second position, so that the clamping spring 2 does not swing back after connecting an electrical conductor 10 due to their pivotal arrangement and due to their spring force in the direction of the first position. For this purpose, the actuating leg 7 of the clamping spring 2 at its end remote from the clamping leg 6 has a holding portion 14 which is bent in the direction of the clamping leg 6. Corresponding to this, the metal part 3 has, in addition to a clamping section 15, a holding section 16 which is bent in the direction of the actuating limb 7. In the in the FIGS. 1 to 7 illustrated preferred embodiment of the terminal 1, the latching between the holding portion 14 of the actuating arm 7 and the holding portion 16 of the metal part 3 is realized by the fact that on the holding portion 14 of the actuating arm 7 two respectively laterally outwardly projecting projections 17 are formed and the holding portion 16 of the metal part 3 has two separate bent detent ends 18. In the locked state of the clamping spring 2 according to Fig. 2 are the projections 17 engaged under the locking ends 18, so that the clamping spring 2 is held in its closed position and can not swing back into its open position.

Wie insbesondere aus den Fig. 1 und 2 ersichtlich ist, weist der Halteabschnitt 14 des Betätigungsschenkels 7 zwei durch einen Schlitz 19 voneinander getrennte Halteschenkel 20 auf, wobei an jedem der beiden Halteschenkel 20 jeweils einer der beiden Vorsprünge 17 ausgebildet ist. Durch die Ausbildung zweier separater Halteschenkel 20 wird die Auslenkung der beiden Halteschenkel 20 beim Verrasten der Klemmfeder 2 in der zweiten Position erleichtert. Darüber hinaus sind die Enden der beiden Halteschenkel 20 nach innen, d. h. in Richtung auf den Klemmschenkel 6 abgebogen, so dass die Halteschenkel 20 beim Herunterdrücken des Betätigungsschenkels 7 durch das Betätigungselement 12 nicht an den Rastenden 18 verkannten.As in particular from the Fig. 1 and 2 it can be seen, the holding portion 14 of the actuating arm 7 has two holding legs 20 separated from each other by a slot 19, one of the two projections 17 being formed on each of the two holding legs 20. Due to the formation of two separate holding legs 20, the deflection of the two holding legs 20 is facilitated when locking the clamping spring 2 in the second position. In addition, the ends of the two holding legs 20 are inwardly, ie bent in the direction of the clamping leg 6, so that the holding legs 20 were not misjudged by pressing the actuating leg 7 by the actuating element 12 at the locking ends 18.

Um das Öffnen der Klemmfeder 2 und damit das Verschwenken der Klemmfeder 2 aus der zweiten Position in die erste Position zu erleichtern, weist das Betätigungselement 2 eine Betätigungswand 21 und zwei seitlich neben der Betätigungswand 21 ausgebildete Entriegelungsabschnitte 22 auf. Die Betätigungswand 21 erstreckt sich dabei in der Ebene des im Halteabschnitt 14 des Betätigungsschenkels 7 ausgebildeten Schlitzes 19, so dass die Bestätigungswand 21 beim Verschwenken der Klemmfeder 2 aus der geschlossenen Position in die geöffnete Position in den Schlitz 19 eintauchen kann. Beim Verschwenken der Klemmfeder 2 aus der geschlossenen Position in die geöffnete Position, wie dies in den Fig. 6 und 7 dargestellt ist, drücken zunächst die beiden Betätigungsabschnitte 22 gegen die beiden Halteschenkel 20 des Halteabschnitts 14, wodurch die Verrastung zwischen den Vorsprüngen 17 und den Rastenden 18 gelöst wird.In order to facilitate the opening of the clamping spring 2 and thus the pivoting of the clamping spring 2 from the second position to the first position, the actuating element 2 has an actuating wall 21 and two unlocking sections 22 formed laterally next to the actuating wall 21. The actuating wall 21 extends in the plane of the formed in the holding portion 14 of the actuating leg 7 slot 19, so that the confirmation wall 21 can dip during pivoting of the clamping spring 2 from the closed position into the open position in the slot 19. When pivoting the clamping spring 2 from the closed position in the open position, as in the Fig. 6 and 7 is shown, first press the two actuating portions 22 against the two holding legs 20 of the holding portion 14, whereby the locking between the projections 17 and the locking ends 18 is released.

Ist in der elektrischen Anschlussklemme 1 ein Leiter 10 eingeführt, so dass der Klemmschenkel 6 entgegen der Federkraft der Klemmfeder 2 ausgelenkt ist, so verschwenkt die Klemmfeder 2 nach dem Lösen der Verrastung aufgrund ihrer Federkraft zunächst selber in eine teilweise geöffnete Position, wie sie in Fig. 7 gezeigt ist. Um die Klemmfeder 2 in die in den Fig. 1 und 3 dargestellte, vollständig geöffnete Position zu verschwenken, muss das Betätigungselement 12 weiter nach oben, d. h. bei der in den Figuren 3 bis 7 dargestellten Orientierung der Anschlussklemme 1 entgegen dem Uhrzeigersinn geschwenkt werden. Dabei gleitet die Betätigungswand 21 des Betätigungselements 12 durch den Schlitz 19 im Halteabschnitt 14 des Betätigungsschenkels 7 bis das Ende der Betätigungswand 21 von innen am Betätigungsschenkel 7 anstößt, so dass beim weiteren Verschwenken des Betätigungselements 12 auch die Klemmfeder 2 weiter in die vollständig geöffnete Position verschwenkt wird. Die vollständig geöffnete Position der Klemmfeder 2 ist dann erreicht, wenn die Klemmfeder 2 mit ihrem Betätigungsschenkel 7 an einem im Gehäuse 5 ausgebildeten Anschlag 23 anschlägt. Dadurch ist die vollständig geöffnete Position der Klemmfeder 2 auch für den Monteur leicht erkennbar.Is in the electrical terminal 1, a conductor 10 is inserted, so that the clamping leg 6 is deflected against the spring force of the clamping spring 2, the clamping spring 2 pivots after loosening the latch due to their spring force initially in a partially open position, as in Fig. 7 is shown. To the clamping spring 2 in the in the Fig. 1 and 3 shown, fully open position to pivot, the actuator 12 must continue upwards, ie when in the FIGS. 3 to 7 shown orientation of the terminal 1 are pivoted counterclockwise. In this case, the actuating wall 21 of the actuating element 12 slides through the slot 19 in the holding portion 14 of the actuating leg 7 until the end of the actuating wall 21 abuts from the inside on the actuating arm 7, so that upon further pivoting of the actuating element 12 and the clamping spring 2 pivots further into the fully open position becomes. The fully open position of the clamping spring 2 is then reached when the clamping spring 2 abuts with its actuating limb 7 on a stop 5 formed in the housing 5. As a result, the fully open position of the clamping spring 2 is easily recognizable even for the fitter.

Bei dem in den Figuren dargestellten Ausführungsbeispiel der erfindungsgemäßen Anschlussklemme 1 handelt es sich um eine Printklemme zum Anschließen eines Leiters 10 an eine Leiterplatte. Hierzu weist das Metallteil 3 mehrere, im dargestellten Ausführungsbeispiel vier Lötanschlussprints 24 auf, die einstückig mit dem Metallteil 3 verbunden sind. Das Metallteil 3 kann somit als einfaches Stanz- und Biegeteil aus einem leitfähigen Flachmaterial hergestellt werden. Ebenso kann die Klemmfeder 2 aus einem Flachmaterial durch Ausstanzen und Abbiegen in ihre in den Figuren dargestellte Form gebracht werden.The exemplary embodiment of the terminal 1 according to the invention shown in the figures is a print terminal for connecting a conductor 10 to a circuit board. For this purpose, the metal part 3 a plurality of, in the illustrated embodiment, four Lötanschlussprints 24, which are integrally connected to the metal part 3. The metal part 3 can thus be made as a simple stamped and bent part of a conductive sheet. Likewise, the clamping spring 2 can be made of a flat material by punching and bending in their shape shown in the figures.

Zur einfachen und bequemen Handhabung des Betätigungselements 12 weist dieses einen über die Stirnfläche 25 des Gehäuses 5 überstehenden Griffabschnitt 26 auf. Das Betätigungselement 12 kann somit einfach mit einem oder zwei Fingern - gemäß den Fig. 3 bis 5 - aus der ersten Position in die zweite Position verschwenkt, d. h. geschlossen werden sowie mit einem oder zwei Fingern - gemäß den Fig. 6 und 7 - aus der zweiten Position in die erste Position verschwenkt, d. h. geöffnet werden.For easy and convenient handling of the actuating element 12, this has a over the end face 25 of the housing 5 projecting handle portion 26. The actuator 12 can thus easily with one or two fingers - according to the Fig. 3 to 5 - pivoted from the first position to the second position, ie closed and with one or two fingers - according to the Fig. 6 and 7 - pivoted from the second position to the first position, that is opened.
