Description

Anschlusseinrichtung zum Anschließen einer elektrischen Leitung  Connecting device for connecting an electrical line
Die Erfindung betrifft eine Anschlusseinrichtung nach dem Oberbegriff des Anspruchs 1. Eine derartige Anschlusseinrichtung dient zum Anschließen einer elektrischen Leitung. Eine solche Anschlusseinrichtung kann beispielsweise an einer elektrischen Anlage, einem Schaltschrank oder einer anderen elektrischen Baugruppe wie zum Beispiel einer Leiterplatte oder dergleichen zum Einsatz kommen, um durch Einstecken eines elektrischen Leiters in eine Stecköffnung den Leiter elektrisch anzuschließen. The invention relates to a connection device according to the preamble of claim 1. Such a connection device is used for connecting an electrical line. Such a connection device can be used for example on an electrical system, a control cabinet or other electrical assembly such as a printed circuit board or the like to electrically connect the conductor by inserting an electrical conductor into a plug-in opening.
Eine solche Anschlusseinrichtung umfasst ein Gehäuse, das eine Stecköffnung zum Einstecken eines elektrischen Leiters aufweist, und ein an dem Gehäuse angeordnetes Federelement, das einen Federschenkel zum Arretieren eines in die Stecköffnung eingesteckten Leiters aufweist. Ein Verstellelement ist verstellbar an dem Gehäuse angeordnet derart, dass durch Verstellen des Verstellelements der Federschenkel zwischen einer Klemmstellung, in der ein in die Stecköffnung eingesteckter Leiter in der Stecköffnung arretierbar ist, und einer Freigabestellung, in der ein Leiter in die Stecköffnung einsteckbar oder ein in die Stecköffnung eingesteckter Leiter aus der Stecköffnung lösbar ist, bewegbar ist. Such a connection device comprises a housing which has a plug-in opening for insertion of an electrical conductor, and a spring element arranged on the housing, which has a spring leg for locking a conductor which is inserted into the plug-in opening. An adjusting element is adjustably arranged on the housing such that by adjusting the adjusting element of the spring leg between a clamping position in which a plugged into the plug opening conductor is locked in the plug opening, and a release position in which a conductor plugged into the plug hole or a in the plug opening plugged conductor is detachable from the insertion opening, is movable.
Bei herkömmlichen Anschlusseinrichtungen dieser Art kann vorgesehen sein, dass mittels eines Werkzeugs auf das Schieberelement einzuwirken ist, um dadurch den Federschenkel des Federelements zu verstellen. Dies kann erforderlich machen, dass ein Nutzer die Anschlusseinrichtung und den gegebenenfalls anzuschließenden elektrischen Leiter genauso wie das Werkzeug gleichzeitig in seinen Händen halten und betätigen muss, was umständlich und unpraktikabel sein kann. In conventional connection devices of this type can be provided that is acted upon by means of a tool on the slider element, thereby to adjust the spring leg of the spring element. This may require that a user must simultaneously hold and operate the connector and any electrical conductor to be connected, as well as the tool, which may be cumbersome and impractical.
Es besteht daher ein Bedürfnis nach einer Anschlusseinrichtung, die eine einfache Handhabung durch einen Nutzer insbesondere zum Einstecken eines elektrischen Leiters oder zum Lösen eines elektrischen Leiters von der Anschlusseinrichtung ermöglicht. There is therefore a need for a connection device which allows easy handling by a user, in particular for inserting an electrical conductor or for releasing an electrical conductor from the connection device.
Bei einer aus der US 8,1 13,858 bekannten Anschlusseinrichtung ist ein Federelement in einem Gehäuse angeordnet und durch ein manuell betätigbares Schieberelement verstellbar. Das Schieberelement ist ausgebildet, auf das Federelement einzuwirken, um ein Anstecken eines Leiters zu ermöglichen, wobei nach Anstecken des Leiters und nach Zurückstellen des Schiebers das Federelement den elektrischen Leiter in elektrisch kontaktierender Weise an dem Gehäuse arretiert. In one known from US 8.1 13,858 connection device, a spring element is arranged in a housing and adjustable by a manually operable slide element. The slider element is adapted to act on the spring element to allow a plugging of a conductor, wherein after plugging the conductor and after Resetting the slider, the spring element locks the electrical conductor in an electrically contacting manner on the housing.
Bei einer aus der DE 20 2009 007 573 U1 bekannten Anschlusseinrichtung ist ein Schieberelement vorgesehen, das zum Verstellen eines Federschenkels eines Federelements verstellbar ist. In one known from DE 20 2009 007 573 U1 connection device, a slide element is provided, which is adjustable for adjusting a spring leg of a spring element.
Bei einer aus der DE 10 2015 1 15 612 A1 bekannten Anschlusseinrichtung in Form einer Anschlussklemme ist an einem Federschenkel eines Federelements ein Verbindungselement geformt, über das der Federschenkel mit einem Betätigungselement in Form eines Schwenkhebels gekoppelt ist derart, dass durch Verschwenken des Betätigungselements der Federschenkel aus einer Klemmstellung in Richtung einer Freigabestellung gezogen werden kann. Bei der aus der DE 10 2015 1 15 612 A1 bekannten Anschlusseinrichtung ist das Verbindungselement einstückig mit dem Federschenkel geformt, durch Umbiegen des als Stanzteil aus Federstahl gefertigten Federelements. Auch abhängig von der Walzrichtung des Federstahls kann für eine solche Umbiegung ein vergleichsweise großer Biegeradius erforderlich sein, was den Bauraum des Federelements erhöhen kann. In one known from DE 10 2015 1 15 612 A1 connection device in the form of a terminal a connecting element is formed on a spring leg of a spring element, via which the spring leg is coupled to an actuating element in the form of a pivot lever such that by pivoting the actuating element of the spring leg a clamping position can be pulled in the direction of a release position. In the connection device known from DE 10 2015 1 15 612 A1, the connecting element is formed integrally with the spring leg, by bending over the spring element produced as a stamped part made of spring steel. Also, depending on the rolling direction of the spring steel, a comparatively large bending radius may be required for such a bend, which may increase the space of the spring element.
Aufgabe der vorliegenden Erfindung ist es, eine Anschlusseinrichtung zum Anschließen eines elektrischen Leiters zur Verfügung zu stellen, die einfach zum Verstellen eines Federelements zwischen einer Klemmstellung und einer Freigabestellung betätigbar ist, bei einfacher Herstellbarkeit des Federelements und bei günstiger Belastbarkeit auch bei wiederholter Betätigung im Betrieb. Object of the present invention is to provide a connection device for connecting an electrical conductor available, which is easy to adjust a spring element between a clamping position and a release position operable, with ease of manufacture of the spring element and favorable load capacity even with repeated operation during operation.
Diese Aufgabe wird durch einen Gegenstand mit den Merkmalen des Anspruchs 1 gelöst. This object is achieved by an article having the features of claim 1.
Demnach weist das Federelement einen an dem Federschenkel angeordneten Betätigungsabschnitt auf, auf den das Verstellelement bei einem Verstellen zum Bewegen des Federschenkels einwirkt und an dem ein Stützabschnitt geformt ist, der ausgebildet ist, bei einem Bewegen des Federschenkels an einem Stützpunkt mit dem Federschenkel in Anlage zu gelangen. Accordingly, the spring element has a arranged on the spring leg operating portion on which the adjusting element acts on an adjustment for moving the spring leg and on which a support portion is formed, which is formed when moving the spring leg at a base with the spring leg in Appendix reach.
Das Verstellen des Federschenkels kann durch Betätigung des Verstellelements erfolgen. Das Verstellelement wirkt hierbei auf den an dem Federschenkel geformten Betätigungsabschnitt ein, um dadurch eine Verstellkraft auf den Federschenkel aufzubringen und den Federschenkel zu verstellen. The adjustment of the spring leg can be done by pressing the adjustment. The adjustment here acts on the formed on the spring leg Operating section, thereby applying an adjusting force on the spring leg and to adjust the spring leg.
Um eine definierte Schwenkachse zum Verstellen des Federschenkels vorzugeben, ist der Stützabschnitt an dem Betätigungsabschnitt geformt. Der Stützabschnitt ist dazu ausgebildet, bei einem Bewegen des Federschenkels mit dem Federschenkel in Anlage zu gelangen, sodass der Stützabschnitt auf den Federschenkel drückt und dadurch einen definierten Schwenkpunkt für den Federschenkel schafft. Dadurch, dass mittels des Stützabschnitts ein definierter Schwenkpunkt an dem Federschenkel geschaffen wird, der vorzugsweise in einem belastbaren Bereich des Federschenkels liegen kann, erfolgt die Belastung an dem Federschenkel auf Biegung an einem definierten Ort in definierter Weise, sodass die Belastung in anderen Bereichen des Federschenkels reduziert sein kann und somit eine Reduzierung der Dimensionierung des Federschenkels in anderen Bereichen ermöglicht wird. In order to predefine a defined pivot axis for adjusting the spring leg, the support section is formed on the actuating section. The support portion is adapted to come into contact with a movement of the spring leg with the spring leg, so that the support portion presses on the spring leg and thereby creates a defined pivot point for the spring leg. Characterized in that by means of the support portion a defined pivot point is provided on the spring leg, which may preferably lie in a resilient region of the spring leg, the load on the spring leg to bending at a defined location in a defined manner, so that the load in other areas of the spring leg can be reduced and thus a reduction of the dimensioning of the spring leg is made possible in other areas.
Insbesondere kann der Federschenkel an dem Ort, an dem sich der Betätigungsabschnitt von dem Federschenkel erstreckt, mit reduziertem Querschnitt dimensioniert werden, was ermöglicht, den Bauraum des Federelements - trotz eines gegebenenfalls erforderlichen großen Biegeradius am Übergang zwischen dem Federschenkel und dem Betätigungsabschnitt - klein zu halten. In particular, the spring leg at the location where the actuating portion extends from the spring leg, be dimensioned with reduced cross-section, which allows the space of the spring element - despite an optionally required large bending radius at the transition between the spring leg and the operating section - to keep small ,
Das Verstellelement kann insbesondere ausgebildet sein, zum Bewegen des Federschenkels in Richtung der Freigabestellung auf den Betätigungsabschnitt einzuwirken. Durch Verstellen des Verstellelements kann der Federschenkel somit aus seiner Klemmstellung in die Freigabestellung überführt werden, indem das Verstellelement auf den Betätigungsabschnitt einwirkt, beispielsweise an dem Betätigungsabschnitt drückt oder an dem Betätigungsabschnitt zieht, sodass dadurch der Federschenkel bewegt wird. Bei Verstellen des Verstellelements wird hierbei der Federschenkel vorzugsweise um eine durch den Stützpunkt weisende Schwenkachse relativ zu dem Gehäuse verschwenkt, sodass der Federschenkel bei Betätigung des Verstellelements eine definierte Schwenkbewegung ausführt. The adjusting element may in particular be designed to act on the actuating section in order to move the spring leg in the direction of the release position. By adjusting the adjustment of the spring leg can thus be transferred from its clamping position to the release position by the adjustment acts on the actuating portion, for example, on the actuating portion presses or pulls on the actuating portion, thereby the spring leg is moved. When adjusting the adjusting element in this case the spring leg is preferably pivoted about a pivot point pointing through the support pivot axis relative to the housing, so that the spring leg performs a defined pivoting movement upon actuation of the adjusting element.
In einer Ausgestaltung ist der Stützabschnitt in der Klemmstellung des Federelements nicht mit dem Federschenkel in Anlage. Erst bei einem Bewegen des Federschenkels, bewirkt durch ein Verstellen des Verstellelements, gelangt der Stützabschnitt an dem Stützpunkt mit dem Federschenkel in Anlage, sodass das Verschwenken des Federschenkels aus der Freigabestellung in Richtung der Klemmstellung um eine durch den Stützpunkt weisende definierte Schwenkachse erfolgen kann. In einer Ausgestaltung ist der Betätigungsabschnitt einstückig mit dem Federschenkel geformt. Das Federelement kann insbesondere insgesamt aus einem Federstahl gefertigt sein. Der Betätigungsabschnitt ist in diesem Fall vorzugsweise durch Umbiegen an dem Federschenkel geformt. Es ergibt sich eine einfache, kostengünstige Herstellbarkeit des Federelements, unter integraler, einstückiger Formung des Federschenkels mit dem Betätigungsabschnitt und dem daran geformten Stützabschnitt. In one embodiment, the support portion in the clamping position of the spring element is not in contact with the spring leg. Only with a movement of the spring leg, caused by an adjustment of the adjusting element, the support section arrives at the Base with the spring leg in Appendix, so that the pivoting of the spring leg from the release position in the direction of the clamping position can be done by a defined by the support point defined pivot axis. In one embodiment, the actuating portion is formed integrally with the spring leg. The spring element can in particular be made entirely from a spring steel. The actuating portion is preferably formed in this case by bending on the spring leg. This results in a simple, inexpensive manufacture of the spring element, under integral, one-piece shaping of the spring leg with the actuating portion and the support portion formed thereon.
In einer Ausgestaltung weist das Federelement einen an den Federschenkel anschließenden Halteschenkel auf. Über den Halteschenkel ist das Federelement relativ zu dem Gehäuse abgestützt, beispielsweise indem der Halteschenkel mit einem Strombalken in Eingriff steht, der den Halteschenkel in Position innerhalb des Gehäuses hält. In one embodiment, the spring element has a holding leg adjoining the spring leg. Via the retaining leg, the spring element is supported relative to the housing, for example by the holding leg is engaged with a current bar, which holds the holding leg in position within the housing.
Der Strombalken kann beispielsweise einen Kontaktabschnitt zum Kontaktieren mit einem in die Stecköffnung eingesteckten Leiter ausbilden. Der Strombalken kann eine L- Form aufweisen, mit einer Basis, zu der der Kontaktabschnitt quer erstreckt ist. An der Basis kann hierbei auch ein Anschluss zum Anschließen eines Steckverbinders zum elektrischen Kontaktieren mit einer an die Anschlusseinrichtung angeschlossenen Leitung geformt sein. Der Halteschenkel kann beispielsweise zu dem Federschenkel umgebogen sein. Der Stützabschnitt des Betätigungsabschnitts kann sich hierbei von dem Betätigungsabschnitt hin zu dem Übergang zwischen dem Federschenkel und dem Halteschenkel erstrecken und an einem von dem Betätigungsabschnitt abliegenden Ende abstützend mit dem Federschenkel zusammenwirken, sodass darüber eine durch den Stützpunkt weisende Schwenkachse zum Verschwenken des Federschenkels vorgegeben wird. The current bar can, for example, form a contact section for contacting with a conductor inserted in the plug-in opening. The current bar may have an L-shape with a base to which the contact portion extends transversely. In this case, a connection for connecting a connector for electrical contacting with a line connected to the connection device can also be formed on the base. The retaining leg can be bent, for example, to the spring legs. The support portion of the actuating portion may in this case extend from the actuating portion to the transition between the spring leg and the retaining leg and cooperating at a distal end of the actuating portion supportingly cooperate with the spring leg, so that above a pointing through the pivot point pivot for pivoting the spring leg is specified.
In einer Ausgestaltung ist der Halteschenkel um eine erste Biegeachse zu dem Federschenkel umgebogen. Der Betätigungsabschnitt ist demgegenüber um eine zur ersten Biegeachse quer gerichtete, zweite Biegeachse zu dem Federschenkel umgebogen. Von dem Betätigungsabschnitt erstreckt sich der Stützabschnitt vorzugsweise in Richtung des Übergangs von dem Federschenkel zu dem Halteschenkel. In one embodiment, the retaining leg is bent around a first bending axis to the spring leg. The actuating portion is in contrast bent around a first bending axis transversely directed, second bending axis to the spring leg. From the operating portion, the support portion extends preferably in the direction of the transition from the spring leg to the retaining leg.
Das Verstellelement kann beispielsweise als Hebelelement ausgebildet sein und um eine Schwenkachse schwenkbar an dem Gehäuse angeordnet sein. In diesem Fall kann das Verstellelement beispielsweise einen zu der Schwenkachse exzentrischen Wirkabschnitt aufweisen, mit dem das Verstellelement bei einem Verstellen auf den Betätigungsabschnitt einwirkt, um darüber den Federschenkel auszulenken und zwischen seiner Klemmstellung und der Freigabestellung zu verstellen. The adjusting element may for example be designed as a lever element and be arranged pivotably about a pivot axis on the housing. In this case, the adjusting element, for example, have an eccentric to the pivot axis effective portion, with which the adjusting element acts on an adjustment on the actuating portion to deflect over the spring leg and adjust between its clamping position and the release position.

Fig. 4 eine gesonderte Ansicht des Federelements. Fig. 1A, 1 B bis 4 zeigen ein Ausführungsbeispiel einer Anschlusseinrichtung 1 , die ein Gehäuse 10 mit einer daran geformten Stecköffnung 100 aufweist. An die Anschlusseinrichtung 1 kann ein elektrischer Leiter 2 in eine Steckrichtung E angesteckt werden, wodurch der Leiter 2 in Eingriff mit der Stecköffnung 100 gelangt, um innerhalb des Gehäuses 10 mit einem Kontaktabschnitt 130 eines Strombalkens 13 elektrisch zu kontaktieren. Fig. 4 is a separate view of the spring element. 1A, 1 B to 4 show an embodiment of a connection device 1, which has a housing 10 with an insertion opening 100 formed thereon. To the Connection device 1, an electrical conductor 2 are plugged into a plug-in direction E, whereby the conductor 2 comes into engagement with the plug opening 100 to electrically contact within the housing 10 with a contact portion 130 of a current bar.
An dem Strombalken 13 ist ein Anschluss 132 geformt, an den ein Steckverbinder einer zugeordneten elektrischen Baugruppe angeschlossen werden kann. Die Anschlusseinrichtung 1 kann beispielsweise Bestandteil einer elektrischen Anlage sein, zum Beispiel an einem Schaltschrank, und ein Anschließen eines elektrischen Leiters 2 an die elektrische Anlage ermöglichen. At the current bar 13, a terminal 132 is formed, to which a connector of an associated electrical assembly can be connected. The connection device 1 may for example be part of an electrical system, for example on a control cabinet, and allow an electrical conductor 2 to be connected to the electrical system.
In dem Gehäuse 10 ist ein Federelement 1 1 eingefasst, das über einen Halteschenkel 1 10 an einer Basis 131 des Strombalkens 13 abgestützt ist und einen Federschenkel 1 1 1 zum Arretieren eines in die Stecköffnung 100 eingesteckten elektrischen Leiters 2 aufweist. Das Federelement 1 1 liegt mit einem Biegeabschnitt 1 16, an dem der Federschenkel 1 1 1 zu dem Halteschenkel 1 10 umgebogen ist, in einer zugeordneten Gehäuseaufnahme 102 des Gehäuses 10 ein und ist darüber in dem Gehäuse 10 eingefasst. Der Federschenkel 1 1 1 ist zwischen unterschiedlichen Stellungen verstellbar. Die mit "A" gekennzeichneten Figuren (Fig. 1A, 2A und 3A) zeigen hierbei das Federelement 1 1 jeweils mit dem Federschenkel 1 10 in einer Klemmstellung, in der ein in die Stecköffnung 100 eingesteckter Leiter 2 in dem Gehäuse 10 arretiert und zudem in elektrisch kontaktierende Anlage mit dem Kontaktabschnitt 130 des Strombalkens 13 gedrückt ist. Die mit "B" gekennzeichneten Figuren (Fig. 1 B, 2B und 3B) zeigen demgegenüber den Federschenkel 1 1 1 in einer Freigabestellung, in der der Federschenkel 1 1 1 von dem Kontaktabschnitt 130 entfernt ist, sodass ein in die Stecköffnung 100 eingesteckter Leiter 2 aus der Stecköffnung 100 entfernt werden kann oder ein elektrischer Leiter 2 ohne große Kraftwirkung in die Stecköffnung 100 zum Kontaktieren mit dem Kontaktabschnitt 130 einsteckbar ist. In the housing 10, a spring element 1 1 is bordered, which is supported on a support leg 1 10 to a base 131 of the current bar 13 and a spring leg 1 1 1 for locking an inserted into the plug opening 100 electrical conductor 2 has. The spring element 1 1 is located with a bending portion 1 16 to which the spring leg 1 1 1 is bent to the holding leg 1 10, in an associated housing receptacle 102 of the housing 10 and is enclosed in the housing 10 above. The spring leg 1 1 1 is adjustable between different positions. The figures marked "A" (FIGS. 1A, 2A and 3A) show the spring element 1 1 in each case with the spring leg 10 in a clamping position in which a conductor 2 inserted into the plug-in opening 100 is locked in the housing 10 and also in FIG electrically contacting system with the contact portion 130 of the current bar 13 is pressed. In contrast, the figures marked "B" (FIGS. 1 B, 2 B and 3 B) show the spring leg 1 1 1 in a release position in which the spring leg 1 1 1 is removed from the contact section 130, so that a conductor inserted into the plug-in opening 100 2 can be removed from the insertion opening 100 or an electrical conductor 2 without great force in the plug-in opening 100 for contacting with the contact portion 130 can be inserted.
Die Anschlusseinrichtung 1 weist ein Verstellelement 12 in Form eines Hebelelements auf, das um eine Schwenkachse 120 schwenkbar an dem Gehäuse 10 gelagert ist. Das Verstellelement 12 weist einen Griffabschnitt 121 auf, an dem ein Nutzer manuell angreifen kann, um das Verstellelement 12 zu dem Gehäuse 10 zu verstellen. Über einen Wirkabschnitt 122, der durch einen exzentrischen Nocken verwirklicht ist, wirkt das Verstellelement 12 bei einem Verstellen auf einen Betätigungsabschnitt 1 12 des Federelements 1 1 1 ein, um darüber den Federschenkel 1 1 1 zu verschwenken. The connection device 1 has an adjusting element 12 in the form of a lever element, which is mounted pivotably on the housing 10 about a pivot axis 120. The adjusting element 12 has a gripping portion 121, on which a user can manually engage in order to adjust the adjusting element 12 to the housing 10. About an effective portion 122, which is realized by an eccentric cam, the acts Adjustment element 12 in an adjustment to an actuating portion 1 12 of the spring element 1 1 1, in order to pivot about the spring leg 1 1 1.
Wie aus der gesonderten Ansicht des Federelements 1 1 gemäß Fig. 4 ersichtlich ist, steht der Betätigungsabschnitt 1 12 von dem Federschenkel 1 1 1 in Richtung des Halteschenkels 1 10 vor und ist einstückig mit dem Federschenkel 1 1 1 geformt. Das Federelement 1 1 ist insgesamt einstückig zum Beispiel aus einem Federstahl geformt und in sich elastisch. Der Betätigungsabschnitt 1 12 ist um eine Biegeachse B2 zu dem Federschenkel 1 1 1 umgebogen. Die Biegeachse B2 am Übergang zwischen dem Betätigungsabschnitt 1 12 und dem Federschenkel 1 1 1 erstreckt sich hierbei quer zu einer Biegeachse B1 , um die der Federschenkel 1 1 1 an dem Biegeabschnitt 1 16 zu dem Halteschenkel 1 10 umgebogen ist. As can be seen from the separate view of the spring element 1 1 according to FIG. 4, the actuating portion 1 12 protrudes from the spring leg 1 1 1 in the direction of the retaining leg 1 10 and is formed integrally with the spring leg 1 1 1. The spring element 1 1 is a total of one piece, for example, formed from a spring steel and elastic in itself. The actuating portion 1 12 is bent around a bending axis B2 to the spring leg 1 1 1. The bending axis B2 at the transition between the actuating portion 1 12 and the spring leg 1 1 1 extends here transversely to a bending axis B1 to which the spring leg 1 1 1 is bent at the bending portion 1 16 to the holding leg 1 10.
An dem Betätigungsabschnitt 1 12 ist ein Flächenabschnitt 1 15 geformt, der eine Anlagefläche für den Wirkabschnitt 122 des Verstellelements 12 bereitstellt, sodass bei einem Verschwenken des Verstellelements 12 der Wirkabschnitt 122 auf den Flächenabschnitt 1 15 einwirkt und darüber eine Hebelwirkung an dem Federschenkel 1 1 1 generiert, aufgrund derer der Federschenkel 1 1 1 aus der Klemmstellung in Richtung der Freigabestellung verschwenkt wird. At the operating portion 1 12, a surface portion 1 15 is formed, which provides a bearing surface for the active portion 122 of the adjusting 12, so that upon pivoting of the adjusting element 12 of the effective portion 122 acts on the surface portion 1 15 and above a lever action on the spring leg 1 1 1 generated, due to which the spring leg 1 1 1 is pivoted from the clamping position in the direction of the release position.
An dem Betätigungsabschnitt 1 12 ist ein Stützabschnitt 1 13 geformt, der sich von dem Betätigungsabschnitt 1 12 in Richtung des Biegeabschnitts 1 16 am Übergang zwischen dem Federschenkel 1 1 1 und dem Halteschenkel 1 10 erstreckt und somit entlang der Biegeachse B2 von dem Betätigungsabschnitt 1 12 vorsteht. Der Stützabschnitt 1 13 ist dazu ausgebildet, bei einem Einwirken des Verstellelements 12 auf den Flächenabschnitt 1 15 an einem Stützpunkt 1 14 mit dem Federschenkel 1 1 1 abstützend in Anlage zu gelangen, um darüber eine Schwenkachse D zum Verschwenken des Federschenkels 1 1 1 aus der Klemmstellung in Richtung der Freigabestellung vorzugeben. On the actuating portion 1 12, a support portion 1 13 is formed, which extends from the actuating portion 1 12 in the direction of the bending portion 1 16 at the transition between the spring leg 1 1 1 and the retaining leg 1 10 and thus along the bending axis B2 of the actuating portion 12th protrudes. The support portion 1 13 is adapted to receive at a contact point of the adjusting element 12 on the surface portion 1 15 at a base 1 14 with the spring leg 1 1 1 abutting to invest about a pivot axis D for pivoting the spring leg 1 1 1 from the Specify clamping position in the direction of the release position.
Wie aus dem Übergang zum Beispiel von Fig. 2A hin zu Fig. 2B ersichtlich ist, wird das Verstellelement 12 zum Verstellen des Federschenkels 1 1 1 aus der Klemmstellung in Richtung der Freigabestellung in eine Schwenkrichtung S1 um die Schwenkachse 120 verschwenkt. Dadurch drückt der Wirkabschnitt 122 des Verstellelements 12 auf den Flächenabschnitt 1 15, sodass eine Hebelwirkung in eine Schwenkrichtung S2 an dem Federschenkel 1 1 1 generiert wird. Aufgrund der Hebelwirkung wird der Stützabschnitt 1 13 an dem Stützpunkt 1 14 in Anlage mit dem Federschenkel 1 1 1 gedrückt, sodass am Orte des Stützpunkts 1 14 eine Abstützung für den Federschenkel 1 1 1 geschaffen wird und der Federschenkel 1 1 1 um die durch den Stützpunkt 1 14 weisende Schwenkachse D verschwenkt wird. As can be seen from the transition, for example, from FIG. 2A to FIG. 2B, the adjusting element 12 is pivoted about the pivot axis 120 for adjusting the spring leg 1 1 1 from the clamping position in the direction of the release position into a pivoting direction S1. As a result, the active section 122 of the adjusting element 12 presses on the surface section 1 15, so that a lever action in a pivoting direction S2 on the Spring leg 1 1 1 is generated. Due to the leverage of the support portion 1 13 at the base 1 14 pressed into contact with the spring leg 1 1 1, so that at the location of the base 1 14 a support for the spring leg 1 1 1 is provided and the spring leg 1 1 1 to the by the Support point 1 14 facing pivot axis D is pivoted.
Weil das Verschwenken des Federschenkels 1 1 1 aus seiner Klemmstellung heraus somit um eine definierte, durch die Abstützung über den Stützabschnitt 1 13 vorgegebene Schwenkachse D erfolgt, erfolgt eine Belastung an dem Federschenkel 1 1 1 auf Biegung insbesondere im Bereich der Schwenkachse D, weniger aber in anderen Abschnitten, insbesondere im Bereich des Übergangs von dem Federschenkel 1 1 1 zum Betätigungsabschnitt 1 12. Dies ermöglicht, wie aus der gesonderten Ansicht des Federelements 1 1 gemäß Fig. 4 ersichtlich, die Breite des Federschenkels 1 1 1 am Orte des Übergangs vom Federschenkel 1 1 1 zum Betätigungsabschnitt 1 12 zu reduzieren, was ermöglicht, den Bauraum des Federelements 1 1 klein zu halten. Because the pivoting of the spring leg 1 1 1 from its clamping position thus takes place around a defined, predetermined by the support on the support portion 1 13 pivot axis D, a load on the spring leg 1 1 1 to bending in particular in the region of the pivot axis D, but less In other sections, in particular in the region of the transition from the spring leg 1 1 1 to the operating portion 1 12. This allows, as can be seen from the separate view of the spring element 1 1 of FIG. 4, the width of the spring leg 1 1 1 at the point of transition from Spring leg 1 1 1 to reduce the operating portion 1 12, which allows to keep the space of the spring element 1 1 small.
Wie aus Fig. 4 ersichtlich, ist zur Fertigung des Federelements 1 1 - insbesondere zur Fertigung des Betätigungsabschnitts 1 12 an dem Federschenkel 1 1 1 - erforderlich, den Betätigungsabschnitt 1 12 zu dem Federschenkel 1 1 1 umzubiegen. Hierzu ist ein vergleichsweise großer Biegeradius erforderlich, der Bauraum in Querrichtung (entlang der Richtung der Biegeachse B1 ) erfordert. Durch Reduzierung der Dimensionierung der Querschnittsfläche des Federschenkels 1 1 1 im Bereich des Übergangs zwischen dem Federschenkel 1 1 1 und dem Betätigungsabschnitt 1 12 kann der Bauraum in Querrichtung reduziert werden, sodass die Umbiegung des Betätigungsabschnitt 1 12 nicht zu einer Vergrößerung des gesamten durch das Federelement 1 1 vereinnahmten Bauraums in Querrichtung führt. As shown in Fig. 4, for the production of the spring element 1 1 - in particular for the production of the actuating portion 1 12 on the spring leg 1 1 1 - required to bend the operating portion 1 12 to the spring leg 1 1 1. For this purpose, a comparatively large bending radius is required, which requires installation space in the transverse direction (along the direction of the bending axis B1). By reducing the dimensioning of the cross-sectional area of the spring leg 1 1 1 in the region of the transition between the spring leg 1 1 1 and the actuating portion 1 12, the space can be reduced in the transverse direction, so that the bend of the actuating portion 1 12 does not increase the total by the spring element 1 1 space taken transversely leads.
Durch Verstellen des Verstellelements 12 zum Bewegen des Federschenkels 1 1 1 aus seiner Klemmstellung heraus wird der Federschenkel 1 1 1 gespannt. Wird das Verstellelement 12 dann zurückgestellt, gelangt der Federschenkel 1 1 1 aufgrund seiner elastischen Spannung selbsttätig zurück in die Klemmstellung und verklemmt einen in die Stecköffnung 100 eingesteckten elektrischen Leiter 2 innerhalb des Gehäuses 10, sodass ein (abisoliertes) Leiterende 20 des Leiters 2 in elektrisch kontaktierende Anlage mit dem Kontaktabschnitt 130 gedrückt wird. Die Anschlusseinrichtung 1 kann auch ein Direktstecken eines elektrischen Leiters 2 ermöglichen, ohne dass das Verstellelement 12 zum Bewegen des Federschenkels 1 1 1 aus der Klemmstellung heraus zu betätigen ist. Hierzu kann ein elektrischer Leiter 2, zum Beispiel mit einer an dem Leiterende 20 angebrachten Aderendhülse, in die Stecköffnung 100 eingesteckt werden, bei in der Klemmstellung befindlichem Federschenkel 1 1 1 . Hierdurch wird, aufgrund der Druckwirkung des Leiters 2, der Federschenkel 1 1 1 ausgelenkt, sodass der Stützabschnitt 1 13 an dem Stützpunkt 1 14 mit dem Federschenkel 1 1 1 in Anlage gelangt und somit wiederum das Verschwenken des Federschenkels 1 1 1 um eine definierte Schwenkachse D erfolgt. By adjusting the adjusting element 12 for moving the spring leg 1 1 1 from its clamping position out of the spring leg 1 1 1 is stretched. If the adjusting element 12 is then reset, the spring leg 1 1 1 automatically returns due to its elastic tension in the clamping position and clamped in the plug opening 100 plugged electrical conductor 2 within the housing 10, so that a (stripped) conductor end 20 of the conductor 2 in electrical contacting system with the contact portion 130 is pressed. The connection device 1 can also allow direct plugging of an electrical conductor 2, without the adjustment element 12 being required to move the spring leg 11 1 out of the clamping position. For this purpose, an electrical conductor 2, for example, with an attached to the conductor end 20 ferrule, are inserted into the insertion opening 100, in befindlichem in the clamping position spring leg 1 1 1. As a result, due to the pressure effect of the conductor 2, the spring leg 1 1 1 deflected, so that the support portion 1 13 at the base 1 14 with the spring leg 1 1 1 comes into abutment and thus turn the pivoting of the spring leg 1 1 1 to a defined pivot axis D takes place.
Der der Erfindung zugrunde liegende Gedanke ist nicht auf die vorangehend geschilderten Ausführungsbeispiele beschränkt, sondern lässt sich auch in gänzlich andersgearteter Weise verwirklichen. Eine Anschlusseinrichtung der hier beschriebenen Art kann zum Anschließen eines elektrischen Leiters an eine beliebige elektrische Baugruppe dienen. Hierbei kann die Anschlusseinrichtung einen (zu dem Federkraftanschluss zusätzlichen) Anschluss zum Anschließen eines Steckverbinders aufweisen. Dies ist jedoch nicht zwingend. Ein Strombalken der Anschlusseinrichtung kann auch auf sonstige Weise an eine elektrische Baugruppe angeschlossen sein. The idea underlying the invention is not limited to the embodiments described above, but can also be realized in a completely different manner. A connection device of the type described here can be used to connect an electrical conductor to any electrical assembly. In this case, the connection device may have a connection (which is additional to the spring force connection) for connecting a connector. However, this is not mandatory. A current bar of the connection device can also be connected in any other way to an electrical assembly.
Bei dem hier beschriebenen Ausführungsbeispiel ist das Verstellelement zum Verstellen des Federelements verschwenkbar. Denkbar und möglich ist aber auch, das Verstellelement zum Beispiel verschiebbar an dem Gehäuse anzuordnen. In the embodiment described here, the adjusting element for adjusting the spring element is pivotable. It is also conceivable and possible, however, to arrange the adjusting element displaceable on the housing, for example.

Bezugszeichenliste In the described embodiment, the adjusting element acts on pressure on an actuating portion on the spring leg. It is also conceivable, however, a coupling with which, for example, a tensile force is transmitted from the adjusting element to the spring leg. LIST OF REFERENCE NUMBERS
