Definitions
- the present invention relates to a connecting terminal for connecting at least one electrical conductor, comprising a clamping element arranged pivotably about an axis between an open position and a clamping position on a receiving element, the clamping element forming a clamping point for the electrical conductor with a contact element, and one for receiving a Operating tool set-up operating arm, wherein a first free leg of the operating arm is pivotally arranged on the clamping element at a distance from its axis, so that the clamping element can be moved from the open position to the clamping position and vice versa by pivoting the operating arm by means of the operating tool. Furthermore, the invention relates to a method for connecting at least one electrical conductor to a connection terminal.
- Such a terminal is, for example, from the document DE 10 2013 108 116 A1 known from the house of the applicant.
- an actuating arm which is movably mounted via a link guide, is moved via an actuating tool in order to close or open a clamping point,
- connection terminals have the disadvantage that they generally comprise a large number of movable individual parts, which require complex and thus cost-intensive production. It is therefore an object of the present invention to propose a connection terminal whose manufacturing complexity is as low as possible, but at the same time is simple and convenient to use and which ensures a reliable connection with an electrical conductor inserted into the connection terminal. Furthermore, the task is to propose a corresponding method for connecting an electrical conductor.
- the object is achieved by an arrangement with the features mentioned in the introduction in that a second free leg of the actuating arm is guided so as to be movable over at least one control cam. This offers the advantage that a reliable clamping effect is achieved when using a minimal number of individual parts.
- the control curve is designed and set up such that the second leg of the actuating arm automatically in the closed position, ie in the Clamped position.
- the connecting terminal according to the invention thus remains in the clamping position independently, without external force being exerted by the actuating tool. Only by swiveling the actuating arm by means of the actuating tool is the second leg guided over the control curve.
- the connecting terminal according to the invention can be set up and designed to be convertible from the clamping position into the open position and vice versa.
- the control curve or guide curve and the second leg form a self-locking mechanical system in the clamping position.
- An expedient embodiment of the invention is characterized in that the at least one control curve is formed by the receiving element.
- the control curve is an integral part of the receiving element. In this way, the manufacturing effort is reduced even further.
- the receiving element is set up on the one hand to hold other parts, such as the clamping element, and on the other hand serves as a cam control for movably guiding the second leg of the actuating arm.
- a preferred development of the invention is characterized in that the receiving element is at least essentially U-shaped, with one side surface in each case comprising the respective control curve.
- the two side parts each form side walls, which form a receiving space for the electrical conductor inserted into the clamping point.
- each of the side surfaces forms one of the control cams, which preferably have the same contour.
- the axis, about which the clamping element is arranged pivotably is supported on both sides on the side surfaces.
- the second leg of both of the control cams is movably guided. It is therefore advantageously possible to conveniently insert the electrical conductor into the receiving space by swiveling it in.
- the at least one control curve has a continuous course which transitions from an open position section via an elevation section to a clamp position section.
- the aforementioned course of the control curve has the advantage that the connecting terminal according to the invention remains in the clamping position automatically.
- the second free leg of the actuating arm is first to be moved over the cantilever section of the control curve by applying an actuating force by means of the actuating tool.
- a transition region between the elevation section and the clamping position section is designed to fall monotonously.
- the increase in the actuating force of the connecting terminal can be influenced during the transfer from the open position to the clamping position.
- the force curve of the actuating force can be preset by presetting a control curve geometry.
- the sloping transition area thus supports the transfer into the clamping position.
- the transition region is preferably curved, but can also be designed to run linearly at least along a partial section.
- the free second leg bears against the at least one control curve, forming a sliding guide. This means that no further components are required and the total number of individual parts required is reduced to a minimum.
- the second leg is set up so that it rests on the at least one control curve.
- An end region of the second free leg, with which it rests on the control cam, is preferably rounded.
- the end region is further preferably formed by an envelope. More preferably, the second leg is selected to be at least as wide as the width of the U-shaped receiving element, so that the second leg lies on the side surfaces designed as control curves.
- a further expedient embodiment of the invention is characterized in that the free second leg bears against the control curves of the side surface surfaces via a guide axis.
- the leading axis offers further functional advantages.
- the free second leg lies linearly on the control cams over the leading axis and allows precise guidance through them. Possible deformations of the free leg and / or the actuating arm due to the forces acting during the actuation process therefore have no influence on the guidance of the free leg through the control cams, so that an exact control curve guidance is guaranteed at all times.
- the guide axis is preferably rotatably mounted on the second leg.
- the end region of the second leg is further preferred formed by an envelope, which is set up as a receiving warehouse for the leading axis.
- the receiving element and the contact element are integrally and electrically conductive. This results in a further reduction in the total number of components.
- the receiving element is preferably made from one piece, for example as a stamped part.
- the side surfaces are further preferably formed by edging.
- the receiving element thus advantageously also forms the contact element, which together with the clamping element forms the contact point for the electrical conductor. More preferably, either soldering pins for mounting the connecting terminal according to the invention or further connecting elements are provided on the receiving element.
- actuating arm is designed as a spring clip.
- the spring clip is therefore in the clamping position under spring preload on the control cam. On the one hand, this ensures reliable contacting and clamping of the electrical conductor in the clamping position and, at the same time, causes it to remain in the clamping position automatically.
- the spring preload by means of the spring clip also provides support for the automatic transfer of the second free leg from a position in which it is located in the region of the camber section to the open position section of the control curve.
- the connecting terminal comprising a clamping element which is arranged on an accommodating element and can be pivoted about an axis between an open position and a clamping position, and wherein the clamping element with a contact element is a clamping point for the electrical conductor forms, comprising the steps: inserting the electrical conductor into the clamping point in the open position, inserting an actuating tool into an actuating arm of the connecting terminal set up for this purpose, pivoting the actuating arm by means of the actuating tool for transferring the clamping element from the open position into the clamping position by means of a first free leg of the Actuating arm, which is pivotally arranged on the clamping element at a distance from its axis, guiding a second leg of the actuating arm over at least one control curve.
- a terminal according to the invention is shown schematically in perspective in the open position.
- the connection terminal shown is in a position in which the terminal point 10 is open, so that a - in the Figures 4 and 5 shown - electrical conductor 11 inserted into the terminal point 10 or this can be removed again.
- the clamping point 10 is formed by a clamping element 12 and a contact element 13.
- the contact element 13 is preferably designed as a current bar.
- the contact element 13 is also set up to contact further electrical assemblies.

- the clamping element 12 is arranged on a receiving element 16 so as to be pivotable about an axis 15.
- the contact element 13 is between the in Figure 1 shown open position and one in the Figure 2 shown clamped position movably. In the clamping position, the electrical conductor 11 inserted into the clamping point 10 is pressed against the contact element 13 by the clamping element 12. In this way, the electrical conductor 11 is mechanically clamped in the clamping point and secured against unwanted detachment from the clamping point 10, and at the same time an electrical contact between the electrical conductor 11 and the contact element 13 is achieved.
- the connecting terminal according to the invention further comprises an actuating arm 17.

- the at least one control curve 23 is particularly preferably formed by the receiving element 16.
- the at least one control curve 23 is an integral part of the receiving element 16 and is designed as a single part.

Description
Die vorliegende Erfindung betrifft eine Anschlussklemme zum Anschließen mindestens eines elektrischen Leiters, umfassend ein zwischen einer Offenstellung und einer Klemmstellung um eine Achse schwenkbar an einem Aufnahmeelement angeordnetes Klemmelement, wobei das Klemmelement mit einem Kontaktelement eine Klemmstelle für den elektrischen Leiter bildet, sowie ein zur Aufnahme eines Betätigungswerkzeuges eingerichteter Betätigungsarm, wobei ein erster freier Schenkel des Betätigungsarmes an dem Klemmelement von dessen Achse beabstandet schwenkbar angeordnet ist, so dass das Klemmelement durch Verschwenken des Betätigungsarmes mittels des Betätigungswerkzeuges von der Offenstellung in die Klemmstellung und umgekehrt überführbar eingerichtet ist. Des Weiteren betrifft die Erfindung ein Verfahren zum Anschließen mindestens eines elektrischen Leiters an eine Anschlussklemme.The present invention relates to a connecting terminal for connecting at least one electrical conductor, comprising a clamping element arranged pivotably about an axis between an open position and a clamping position on a receiving element, the clamping element forming a clamping point for the electrical conductor with a contact element, and one for receiving a Operating tool set-up operating arm, wherein a first free leg of the operating arm is pivotally arranged on the clamping element at a distance from its axis, so that the clamping element can be moved from the open position to the clamping position and vice versa by pivoting the operating arm by means of the operating tool. Furthermore, the invention relates to a method for connecting at least one electrical conductor to a connection terminal.
Eine derartige Anschlussklemme ist beispielsweise aus dem Dokument
Die bekannten Anschlussklemmen weisen den Nachteil auf, dass diese in der Regel eine Vielzahl an beweglichen Einzelteilen umfassen, die eine aufwändige und damit kostenintensive Fertigung bedingen.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Anschlussklemme vorzuschlagen, deren Fertigungskomplexität möglichst gering ist, zugleich jedoch einfach und komfortabel zu bedienen ist und eine zuverlässige Klemmverbindung mit einem in die Anschlussklemme eingeführten elektrischen Leiter gewährt. Des Weiteren besteht die Aufgabe darin, ein entsprechendes Verfahren zum Anschluss eines elektrischen Leiters vorzuschlagen.
Die Aufgabe wird durch eine Anordnung mit den eingangs genannten Merkmalen dadurch gelöst, dass ein zweiter freier Schenkel des Betätigungsarmes über mindestens eine Steuerkurve beweglich geführt ist. Dies bietet den Vorteil, dass bei Verwendung einer minimalen Einzelteilzahl eine zuverlässige Klemmwirkung erzielt wird. Die Steuerkurve ist derart ausgebildet und eingerichtet, dass der zweite Schenkel des Betätigungsarms selbsttätig in der geschlossenen Position, d.h. in der Klemmstellung, gehalten wird. Die erfindungsgemäße Anschlussklemme verharrt so - ohne äußere Krafteinwirkung mittels des Betätigungswerkzeugs - eigenständig in der Klemmstellung. Erst durch Schwenken des Betätigungsarmes mittels des Betätigungswerkzeugs wird der zweite Schenkel über die Steuerkurve geführt. Auf diese Weise ist die erfindungsgemäße Anschlussklemme von der Klemm- in die Offenstellung und umgekehrt überführbar eingerichtet und ausgebildet. Die Steuerkurve bzw. Leitkurve und der zweite Schenkel bilden ein in der Klemmstellung sich selbst verriegelndes mechanisches System. Besonders vorteilhaft sind die geringe Anzahl erforderlicher Einzelteile und die damit verbundene minimalistische Kinematik, wodurch der Fertigungsaufwand wesentlich reduziert ist.The known connection terminals have the disadvantage that they generally comprise a large number of movable individual parts, which require complex and thus cost-intensive production.
It is therefore an object of the present invention to propose a connection terminal whose manufacturing complexity is as low as possible, but at the same time is simple and convenient to use and which ensures a reliable connection with an electrical conductor inserted into the connection terminal. Furthermore, the task is to propose a corresponding method for connecting an electrical conductor.
The object is achieved by an arrangement with the features mentioned in the introduction in that a second free leg of the actuating arm is guided so as to be movable over at least one control cam. This offers the advantage that a reliable clamping effect is achieved when using a minimal number of individual parts. The control curve is designed and set up such that the second leg of the actuating arm automatically in the closed position, ie in the Clamped position. The connecting terminal according to the invention thus remains in the clamping position independently, without external force being exerted by the actuating tool. Only by swiveling the actuating arm by means of the actuating tool is the second leg guided over the control curve. In this way, the connecting terminal according to the invention can be set up and designed to be convertible from the clamping position into the open position and vice versa. The control curve or guide curve and the second leg form a self-locking mechanical system in the clamping position. The small number of individual parts required and the associated minimalistic kinematics are particularly advantageous, as a result of which the production outlay is significantly reduced.
Eine zweckmäßige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass die mindestens eine Steuerkurve durch das Aufnahmeelement gebildet ist. Anders ausgedrückt ist die Steuerkurve integraler Bestandteil des Aufnahmeelements. Auf diese Weise wird der Fertigungsaufwand noch weiter reduziert. Das Aufnahmeelement ist einerseits eingerichtet, weitere Teile, wie beispielsweise das Klemmelement, zu halten und dient andererseits als Kurvensteuerung zur beweglichen Führung des zweiten Schenkels des Betätigungsarmes.An expedient embodiment of the invention is characterized in that the at least one control curve is formed by the receiving element. In other words, the control curve is an integral part of the receiving element. In this way, the manufacturing effort is reduced even further. The receiving element is set up on the one hand to hold other parts, such as the clamping element, and on the other hand serves as a cam control for movably guiding the second leg of the actuating arm.
Eine bevorzugte Weiterbildung der Erfindung zeichnet sich dadurch aus, dass das Aufnahmeelement zumindest im Wesentlichen u-profilförmig ausgebildet ist, wobei jeweils eine Seitenfläche die jeweilige Steuerkurve umfasst. Die beiden Seitenteile bilden so jeweils Seitenwände, die einen Aufnahmeraum für den in die Klemmstelle eingeführten elektrischen Leiter bilden. Besonders vorteilhaft ist, dass jede der Seitenflächen jeweils eine der Steuerkurven bildet, die vorzugsweise den gleichen Konturverlauf aufweisen. Auf diese Weise ist die Achse, um die das Klemmelement schwenkbar angeordnet ist, beidseitig an den Seitenflächen gelagert. Zugleich wird der zweite Schenkel beider der Steuerkurven beweglich geführt. Vorteilhafterweise ist es daher möglich, den elektrischen Leiter komfortabel durch Einschwenken in den Aufnahmeraum einzubringen.A preferred development of the invention is characterized in that the receiving element is at least essentially U-shaped, with one side surface in each case comprising the respective control curve. The two side parts each form side walls, which form a receiving space for the electrical conductor inserted into the clamping point. It is particularly advantageous that each of the side surfaces forms one of the control cams, which preferably have the same contour. In this way, the axis, about which the clamping element is arranged pivotably, is supported on both sides on the side surfaces. At the same time, the second leg of both of the control cams is movably guided. It is therefore advantageously possible to conveniently insert the electrical conductor into the receiving space by swiveling it in.
Gemäß einer weiteren bevorzugten Ausbildung der Erfindung weist die mindestens eine Steuerkurve einen von einem Offenstellungsabschnitt über einen Überhöhungsabschnitt in einen Klemmstellungsabschnitt übergehenden stetigen Verlauf auf. Der vorgenannte Verlauf der Steuerkurve weist den Vorteil auf, dass die erfindungsgemäße Anschlussklemme selbsttätig der Klemmstellung verharrt. Um von der Offenstellung in die Klemmstellung oder umgekehrt zu gelangen, ist der zweite freie Schenkel des Betätigungsarmes zunächst durch Aufbringen einer Betätigungskraft mittels des Betätigungswerkzeuges über den Überhöhungsabschnitt der Steuerkurve zu bewegen.According to a further preferred embodiment of the invention, the at least one control curve has a continuous course which transitions from an open position section via an elevation section to a clamp position section. The aforementioned course of the control curve has the advantage that the connecting terminal according to the invention remains in the clamping position automatically. To move from the open position in to reach the clamping position or vice versa, the second free leg of the actuating arm is first to be moved over the cantilever section of the control curve by applying an actuating force by means of the actuating tool.
Eine weitere zweckmäßige Ausbildung der Erfindung ist dadurch gekennzeichnet, dass ein Übergangsbereich zwischen dem Überhöhungsabschnitt und dem Klemmstellungsabschnitt monoton fallend ausgebildet ist. Dadurch kann der Anstieg der Betätigungskraft der Anschlussklemme während des Überführens von der Offenstellung in die Klemmstellung beeinflußt werden. Mit anderen Worten ist der Kraftverlauf der Betätigungskraft durch Vorgabe einer Steuerkurvengeometrie voreinstellbar eingerichtet.. Der abfallend ausgebildete Übergangsbereich unterstützt so die Überführung in die Klemmstellung. Der Übergangsbereich ist vorzugweise gekrümmt ausgebildet, kann jedoch auch zumindest entlang eines Teilabschnitts linear verlaufend ausgebildet sein.Another expedient embodiment of the invention is characterized in that a transition region between the elevation section and the clamping position section is designed to fall monotonously. As a result, the increase in the actuating force of the connecting terminal can be influenced during the transfer from the open position to the clamping position. In other words, the force curve of the actuating force can be preset by presetting a control curve geometry. The sloping transition area thus supports the transfer into the clamping position. The transition region is preferably curved, but can also be designed to run linearly at least along a partial section.
Gemäß einer weiteren bevorzugten Ausführungsform liegt der freie zweite Schenkel unter Bildung einer Gleitführung an der mindestens einen Steuerkurve an. So werden keine weiteren Bauteile benötigt und die Gesamtzahl der erforderlichen Einzelteile auf ein Minimum reduziert. Der zweite Schenkel ist so eingerichtet, dass dieser auf der mindestens einen Steuerkurve aufliegt. Vorzugsweise ist ein Endbereich des zweiten freien Schenkels, mit dem dieser auf der Steuerkurve aufliegt, abgerundet ausgebildet. Weiter bevorzugt wird der Endbereich durch einen Umschlag gebildet. Weiter bevorzugt ist der zweite Schenkel mindestens so breit gewählt, wie die Breite des u-profilförmigen Aufnahmeelements, so dass der zweite Schenkel jeweils auf den als Steuerkurven ausgebildeten Seitenflächen aufliegt.According to a further preferred embodiment, the free second leg bears against the at least one control curve, forming a sliding guide. This means that no further components are required and the total number of individual parts required is reduced to a minimum. The second leg is set up so that it rests on the at least one control curve. An end region of the second free leg, with which it rests on the control cam, is preferably rounded. The end region is further preferably formed by an envelope. More preferably, the second leg is selected to be at least as wide as the width of the U-shaped receiving element, so that the second leg lies on the side surfaces designed as control curves.
Eine weitere zweckmäßige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass der freie zweite Schenkel über eine Leitachse an den Steuerkurven der Seitenflächenflächen anliegt. Die Leitachse bietet weitere funktionstechnische Vorteile. So liegt der freie zweite Schenkel über die Leitachse linienförmig auf den Steuerkurven auf und erlaubt eine präzise Führung durch diese. Mögliche Verformungen des freien Schenkels und/oder des Betätigungsarmes aufgrund der wirkenden Kräfte während des Betätigungsvorgangs nehmen daher keinen Einfluss auf die Führung des freien Schenkels durch die Steuerkurven, so dass zu jeder Zeit eine exakte Steuerkurvenführung gewährleistet ist. Vorzugsweise ist die Leitachse an dem zweiten Schenkel drehbar gelagert. Weiter bevorzugt ist der Endbereich des zweiten Schenkels durch einen Umschlag gebildet, der als Aufnahmelager für die Leitachse eingerichtet ist.A further expedient embodiment of the invention is characterized in that the free second leg bears against the control curves of the side surface surfaces via a guide axis. The leading axis offers further functional advantages. The free second leg lies linearly on the control cams over the leading axis and allows precise guidance through them. Possible deformations of the free leg and / or the actuating arm due to the forces acting during the actuation process therefore have no influence on the guidance of the free leg through the control cams, so that an exact control curve guidance is guaranteed at all times. The guide axis is preferably rotatably mounted on the second leg. The end region of the second leg is further preferred formed by an envelope, which is set up as a receiving warehouse for the leading axis.
Gemäß einer weiteren bevorzugten Ausbildung der Erfindung sind das Aufnahmeelement und das Kontaktelement einstückig und elektrisch leitfähig ausgebildet. Hierdurch wird eine weitere Reduktion der Gesamtbauteilanzahl erreicht. Vorzugsweise ist das Aufnahmeelement aus einem Stück, beispielsweise als Stanzteil gefertigt. Weiter bevorzugt sind die Seitenflächen durch Aufkanten gebildet. Das Aufnahmeelement bildet so vorteilhafterweise zugleich das Kontaktelement, das zusammen mit dem Klemmelement die Kontaktstelle für den elektrischen Leiter bildet. Weiter bevorzugt sind an dem Aufnahmeelement entweder Lötpins zur Leiterplattenmontage der erfindungsgemäßen Anschlussklemme oder weitere Anschlusselemente vorgesehen.According to a further preferred embodiment of the invention, the receiving element and the contact element are integrally and electrically conductive. This results in a further reduction in the total number of components. The receiving element is preferably made from one piece, for example as a stamped part. The side surfaces are further preferably formed by edging. The receiving element thus advantageously also forms the contact element, which together with the clamping element forms the contact point for the electrical conductor. More preferably, either soldering pins for mounting the connecting terminal according to the invention or further connecting elements are provided on the receiving element.
Eine weitere zweckmäßige Ausbildung der Erfindung ist dadurch gekennzeichnet, dass der Betätigungsarm als Federbügel ausgebildet ist. Der Federbügel liegt daher in der Klemmstellung unter Federvorspannung an der Steuerkurve an. So wird einerseits ein zuverlässiges Kontaktieren und Klemmen des elektrischen Leiters in der Klemmstellung gewährleistet und zugleich das selbsttätige Verharren in der Klemmstellung bewirkt. Die Federvorspannung mittels des Federbügels bewirkt zudem eine Unterstützung beim selbsttätigen Überführen des zweiten freien Schenkels aus einer Position, in der dieser sich im Bereich des Überhöhungsabschnitts befindet, in den Offenstellungsabschnitt der Steuerkurve.Another expedient embodiment of the invention is characterized in that the actuating arm is designed as a spring clip. The spring clip is therefore in the clamping position under spring preload on the control cam. On the one hand, this ensures reliable contacting and clamping of the electrical conductor in the clamping position and, at the same time, causes it to remain in the clamping position automatically. The spring preload by means of the spring clip also provides support for the automatic transfer of the second free leg from a position in which it is located in the region of the camber section to the open position section of the control curve.
Des Weiteren wird die Aufgabe durch ein entsprechendes Verfahren mit den eingangs genannten Merkmalen gelöst, wobei die Anschlussklemme ein zwischen einer Offenstellung und einer Klemmstellung um eine Achse schwenkbar an einem Aufnahmeelement angeordnetes Klemmelement umfasst, und wobei das Klemmelement mit einem Kontaktelement eine Klemmstelle für den elektrischen Leiter bildet, umfassend die Schritte: Einlegen des elektrischen Leiters in die Klemmstelle in der Offenstellung, Einführen eines Betätigungswerkzeuges in einen dazu eingerichteten Betätigungsarm der Anschlussklemme, Schwenken des Betätigungsarmes mittels des Betätigungswerkzeugs zum Überführen des Klemmelements von der Offenstellung in die Klemmstellung mittels eines ersten freien Schenkels des Betätigungsarmes, der an dem Klemmelement von dessen Achse beabstandet schwenkbar angeordnet ist, Führen eines zweiten Schenkels des Betätigungsarmes über mindestens eine Steuerkurve. Die Vorteile des erfindungsgemäßen Verfahrens ergeben sich in analoger Weise zu den bereits zuvor genannten Vorteilen der erfindungsgemäßen Anschlussklemme, so dass zur Vermeidung von Wiederholung hierauf verwiesen wird.Furthermore, the object is achieved by a corresponding method with the features mentioned at the outset, the connecting terminal comprising a clamping element which is arranged on an accommodating element and can be pivoted about an axis between an open position and a clamping position, and wherein the clamping element with a contact element is a clamping point for the electrical conductor forms, comprising the steps: inserting the electrical conductor into the clamping point in the open position, inserting an actuating tool into an actuating arm of the connecting terminal set up for this purpose, pivoting the actuating arm by means of the actuating tool for transferring the clamping element from the open position into the clamping position by means of a first free leg of the Actuating arm, which is pivotally arranged on the clamping element at a distance from its axis, guiding a second leg of the actuating arm over at least one control curve. The advantages of the method according to the invention result in an analogous manner to the advantages of the connecting terminal according to the invention already mentioned, so that reference is made to avoid repetition.

Ein zweiter freier Schenkel 22 des Betätigungsarms 17 ist über mindestens eine Steuerkurve 23 beweglich geführt. Besonders bevorzugt ist die mindestens eine Steuerkurve 23 durch das Aufnahmeelement 16 gebildet. Anders ausgedrückt ist die mindestens eine Steuerkurve 23 integraler Bestandteil des Aufnahmeelements 16 und als ein einziges Teil ausgeführt.A second
Das Aufnahmeelement 16 ist vorzugsweise zumindest im Wesentlichen u-profilförmig ausgebildet, weist also eine U-Form bzw. eine im Wesentlichen u-förmige Gestalt auf. Das Aufnahmeelement 16 weist Seitenflächen 24 auf, die über ein dazwischenliegendes Basiselement 25 miteinander verbunden sind. Vorzugsweise bildet das Basiselement 25 zugleich das Kontaktelement 13. Das Kontaktelement 13 kann jedoch alternativ auch auf dem Basiselement 25 angeordnet sein (in der Zeichnung nicht gezeigt). Jede der Seitenflächen 24 umfasst vorteilhafterweise jeweils eine der Steuerkurven 23. Der Verlauf bzw. die Kontur jeweils beider der Steuerkurven sind weiter bevorzugt identisch ausgebildet.The receiving
Vorteilhafterweise weist die mindestens eine Steuerkurve 23 einen von einem Offenstellungsabschnitt 26 über einen Überhöhungsabschnitt 27 in einen Klemmstellungsabschnitt 28 übergehenden stetigen Verlauf auf. Wie in der Zeichnung gezeigt umfasst die Steuerkurve einen stetigen Kurvenverlauf, der grob in die vorgenannten Abschnitte eingeteilt ist. Bezüglich des Basiselements 25 als Bezugsebene ist der Verlauf der Steuerkurve 23 in dem Überhöhungsabschnitt 27 überhöht, übersteigt also in jedem Fall das Niveau des Offenstellungsabschnitts 26 sowie des Klemmstellungsabschnitts 28 der Steuerkurve 23. Weiter bevorzugt ist das Niveau des Klemmstellungsabschnitts 28 bezüglich des Basiselements tieferliegend gewählt, als das Niveau des Offenstellungsabschnitts 26, insbesondere ist ein Übergangsbereich 29 zwischen dem Überhöhungsabschnitt 27 und dem Klemmstellungsabschnitt 28 monoton fallend ausgebildet. Mit anderen Worten wird der zweite freie Schenkel 22 beim Schwenken des Betätigungsarmes 17 mittels des Betätigungswerkzeugs 18 ausgehend von dem Offenstellungsabschnitt 26 mittels der Steuerkurve 23 über den Überhöhungsabschnitt 27 geführt, von dem aus dieser über den monoton in Richtung des Klemmstellungsabschnitts 28 fallenden Übergangsbereich 29 geführt wird.Advantageously, the at least one

Die Auflagekraft, mit der der zweite freie Schenkel 22 in Richtung der Steuerkurven 23 drückt, wird so mittels der Leitachse linienförmig auf die Steuerkurven 23 übertragen.The free

Vorzugsweise ist der Betätigungsarm 17 als Federbügel ausgebildet. Mittels des als Federbügel ausgebildeten Betätigungsarms 17 wird der freie zweite Schenkel 22 unter Federvorspannung gegen die mindestens eine Steuerkurve 23 gezogen. Vorzugsweise ist der Federbügel derart eingerichtet, dass in der Offenstellung keine Federvorspannung wirkt, diese jedoch beim Verschwenken in die Klemmstellung stetig zunimmt.

Der elektrische Leiter 11 wird zunächst in die Klemmstelle 10 der Anschlussklemme, die sich in der Offenstellung befindet, eingelegt. Anschließend wird das Betätigungswerkzeug 18 in den dazu eingerichteten Betätigungsarm 17 eingeführt.
