Description

Die Erfindung betrifft eine Anschlussklemme zum Verbinden eines elektrischen Leiters mit einer Sammelschiene.The invention relates to a connection terminal for connecting an electrical conductor to a busbar.

Elektrische Anschlussklemmen sind in einer Vielzahl von Ausführungsformen bekannt. Anschlussklemmen können beispielsweise zum Anschluss eines Leiters an eine Leiterplatte als sogenannte Printklemme oder - wie im Rahmen der vorliegenden Patentanmeldung - zum Verbinden eines elektrischen Leiters mit einer Sammelschiene ausgebildet sein. Als ein Anwendungsbeispiel derartiger Anschlussklemmen sind seit vielen Jahren Schirmklemmen bekannt, mit denen der Kabelschirm eines in der Regel mehradrigen Kabels an einer Sammelschiene angeschlossen werden kann. Derartige Schirmklemmen sind aus dem Katalog "Reihenklemmen CLIPLINE 1 2011", Seiten 546 - 548 der Phoenix Contact GmbH & Co. KG bekannt.Electrical connection terminals are known in a large number of embodiments. Connection terminals can be designed, for example, for connecting a conductor to a printed circuit board as a so-called print terminal or - as in the context of the present patent application - for connecting an electrical conductor to a busbar. As an application example of such connection terminals, shield clamps have been known for many years, with which the cable shield of a generally multi-core cable can be connected to a busbar. Such shield clamps are from the Catalog "Terminal Blocks CLIPLINE 1 2011", pages 546 - 548 from Phoenix Contact GmbH & Co. KG known.

Die bekannten Schirmklemmen weisen einen näherungsweise U-förmigen metallischen Anschlusskörper auf, wobei in den beiden Schenkeln des Anschlusskörpers Schlitze ausgebildet sind, mit denen die Schirmklemme auf eine Sammelschiene mit vorgegebener Dicke aufgesteckt werden kann. Zur Kontaktierung des Kabelschirms eines anzuschließenden Kabels ist eine Rändelschraube vorgesehen, über die ein großflächiges, federndes Druckstück höhenverstellbar ist, so dass das anzuschließende Kabel zwischen dem Druckstück und der Sammelschiene eingeklemmt werden kann.The known shield clamps have an approximately U-shaped metallic connection body, with slots being formed in the two legs of the connection body with which the shield clamp can be plugged onto a busbar with a predetermined thickness. To contact the cable shield of a cable to be connected, a knurled screw is provided, via which a large, resilient pressure piece can be adjusted in height so that the cable to be connected can be clamped between the pressure piece and the busbar.

Die bekannten Anschlussklemmen sind aufgrund ihrer Ausgestaltung und ihres Anschlussprinzips ausschließlich zum Anschließen des Kabelschirms eines Kabels an eine Sammelschiene geeignet, die mit Bezugspotential verbunden ist. In der Regel wird dazu die Sammelschiene über Auflageböcke mit einer Tragschiene verbunden, auf der dann auch mehrere Reihenklemmen angeordnet sind, an die die einzelnen Adern des mehradrigen Kabels angeschlossen werden.Due to their design and their connection principle, the known connection terminals are only suitable for connecting the cable shield of a cable to a busbar that is connected to reference potential. As a rule, the busbar is connected to a support rail via support blocks, on which several terminal blocks are then arranged, to which the individual wires of the multi-core cable are connected.

Die DE 201 19 510 U1 offenbart einen Sammelanschluss zum Verbinden mehrerer elektrischer Leiter mit einer Sammelschiene, wobei die Anschlussklemme mehrere Federelement als Leiteranschlusselemente und eine Gruppen-Stromschiene aufweist. Bei dem bekannten Sammelanschluss sind Stahlhaltefedern vorgesehen, die die Stromschiene mit der Sammelschiene verklammern. Um ein ungewolltes Abziehen des Sammelanschlusses von der Sammelschiene zu verhindern, ist am Gehäuse des Sammelanschlusses eine Hinterrastung vorgesehen, die die Sammelschiene hintergreift.the DE 201 19 510 U1 discloses a collective terminal for connecting a plurality of electrical conductors to a busbar, the connecting terminal has a plurality of spring elements as conductor connection elements and a group busbar. In the known collective connection, steel retaining springs are provided which clamp the busbar to the busbar. In order to prevent the collective connection from being pulled unintentionally from the busbar, a rear catch is provided on the housing of the collective connection, which engages behind the busbar.

Die DE 197 53 076 C1 offenbart eine elektrische Anschlussklemme zur Anordnung auf einer Leiterplatte, an die mindestens ein elektrischer Leiter anschließbar ist. Die bekannte Anschlussklemme weist ein Gehäuse auf, in dem ein Leiteranschlusselement und ein Strombalken angeordnet sind. Außerdem sind in dem Gehäuse eine Leitereinführungsöffnung und eine Aufnahme für eine Leiterplatte ausgebildet. Der Strombalken ragt mit einem Ende aus dem Gehäuse hinaus, so dass dieses als Kontaktschenkel dienende Ende eine Kontaktfläche auf einer Leiterplatte kontaktiert, die in die Aufnahme eingesteckt ist. Dadurch kann die Anschlussklemme auf einer Leiterplatte mit SMD-Lötflächen ohne durchgehende Bohrungen angeordnet werden.the DE 197 53 076 C1 discloses an electrical connection terminal for arrangement on a printed circuit board, to which at least one electrical conductor can be connected. The known connection terminal has a housing in which a conductor connection element and a current bar are arranged. In addition, a conductor insertion opening and a receptacle for a circuit board are formed in the housing. One end of the current bar protrudes from the housing, so that this end, which serves as a contact leg, contacts a contact surface on a printed circuit board which is plugged into the receptacle. As a result, the connection terminal can be arranged on a circuit board with SMD soldering surfaces without through-holes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anschlussklemme zum Verbinden eines elektrischen Leiters mit einer Sammelschiene anzugeben, bei der der Anschluss an die Sammelschiene möglichst einfach erfolgt. Dabei soll eine sichere elektrische Verbindung zwischen dem anzuschließenden Leiter und der Sammelschiene auch dann gewährleistet sein, wenn die Sammelschienen in ihrer Dicke gewisse Toleranzen aufweisen.The present invention is based on the object of specifying a connection terminal for connecting an electrical conductor to a busbar, in which connection to the busbar is as simple as possible. A secure electrical connection between the conductor to be connected and the busbar should also be ensured if the busbars have certain tolerances in terms of their thickness.

Diese Aufgabe ist bei einer Anschlussklemme zum Verbinden eines elektrischen Leiters mit einer Sammelschiene mit den Merkmalen des Patentanspruchs 1 gelöst. Die Anschlussklemme weist ein Gehäuse auf, in dem ein Leiteranschlusselement und ein Strombalken angeordnet sind. In dem Gehäuse sind darüber hinaus eine Leitereinführungsöffnung zum Einführen des anzuschließenden elektrischen Leiters und eine Sammelschienenaufnahme zur Aufnahme der Sammelschiene ausgebildet. Ein mittels des Leiteranschlusselements angeschlossener Leiter ist dann über den Strombalken mit der in der Sammelschienenaufnahme angeordneten Sammelschiene elektrisch leitend verbunden.This object is achieved in a connection terminal for connecting an electrical conductor to a busbar with the features of claim 1. The connection terminal has a housing in which a conductor connection element and a current bar are arranged. In addition, a conductor insertion opening for inserting the electrical conductor to be connected and a busbar receptacle for receiving the busbar are formed in the housing. A conductor connected by means of the conductor connection element is then connected in an electrically conductive manner via the current bar to the busbar arranged in the busbar receptacle.

Bei der Erfindung ist von besonderer Bedeutung, dass der Strombalken verschiebbar im Gehäuse gelagert ist, und dass ein Federelement derart im Gehäuse angeordnet ist, dass das Federelement den Strombalken mit einer Kraft in Richtung der Sammelschienenaufnahme beaufschlagt. Durch das Federelement wird gewährleistet, dass stets eine ausreichende und weitestgehend gleichbleibende Kontaktkraft zwischen dem Strombalken und einer in der Sammelschienenaufnahme eingeführten Sammelschiene besteht, so dass ein guter elektrischer Kontakt zwischen den Strombalken und der Sammelschiene gewährleistet ist. Durch die verschiebbare Anordnung des Strombalkens im Gehäuse im Zusammenspiel mit der durch das Federelement auf den Strombalken wirkenden Kraft in Richtung der Sammelschienenaufnahme können Toleranzen bei der Dicke der verwendeten Sammelschiene zuverlässig ausgeglichen werden.In the invention it is of particular importance that the current bar is slidably mounted in the housing, and that a spring element is arranged in the housing in such a way that the spring element applies a force to the current bar in the direction of the busbar receptacle. The spring element ensures that there is always a sufficient and largely constant contact force between the current bar and a busbar inserted in the busbar receptacle, so that good electrical contact between the current bar and the busbar is ensured. Due to the displaceable arrangement of the current bar in the housing in conjunction with the force acting on the current bar through the spring element in the direction of the busbar receptacle, tolerances in the thickness of the busbar used can be reliably compensated for.

Gemäß einer vorteilhaften Ausgestaltung der erfindungsgemäßen Anschlussklemme ist das Federelement als im wesentlichen U-förmige oder V-förmige Schenkelfeder ausgebildet, die zwei Schenkel aufweist. Der erste Schenkel stützt sich dabei als eine Art Anlageschenkel an einem Widerlager im Gehäuse ab, während der zweite Schenkel mit dem Strombalken in Kontakt ist. Der Kontakt zwischen dem zweiten Schenkel der Schenkelfeder und dem Strombalken kann dabei dadurch realisiert sein, dass der zweite Schenkel der Schenkelfeder mit seinem freien Ende in eine entsprechende Ausnehmung im Strombalken eingreift. Dadurch ist der zweite Schenkel mit dem Strombalken formschlüssig verbunden, so dass sich die Position des freien Endes des zweiten Schenkels zum Strombalken nicht verändert.According to an advantageous embodiment of the connection terminal according to the invention, the spring element is designed as an essentially U-shaped or V-shaped leg spring which has two legs. The first leg is supported as a kind of contact leg on an abutment in the housing, while the second leg is in contact with the current bar. The contact between the second leg of the leg spring and the current bar can be implemented in that the second leg of the leg spring engages with its free end in a corresponding recess in the current bar. As a result, the second leg is positively connected to the current bar, so that the position of the free end of the second leg relative to the current bar does not change.

Gemäß einer bevorzugten, weil konstruktiv besonders einfach zu realisierenden Ausgestaltung der Erfindung liegt der zweite Schenkel der Schenkelfeder einfach an dem der Sammelschienenaufnahme abgewandten Ende des Strombalkens an bzw. das Ende des Strombalkens drückt gegen den zweiten Schenkel der Schenkelfeder. Auf die Ausbildung einer Ausnehmung im Strombalken kann hierbei verzichtet werden. Bei dieser Ausgestaltung ist die Schenkelfeder mit ihren beiden Schenkeln zwischen dem Widerlager im Gehäuse und dem Strombalken eingespannt, wobei die Schenkelfeder zusätzlich durch entsprechende Rippen oder Haltedome im Gehäuse in ihrer Position gesichert sein kann. Ist in die Sammelschienenaufnahme eine Sammelschiene eingesteckt, so wird der Strombalken aus seiner Grundposition etwas in Richtung der Schenkelfeder gedrückt, wodurch die Schenkelfeder etwas entgegen ihrer Federkraft zusammengedrückt wird. Aus der Federkraft der Schenkelfeder resultiert dann die Kraft, mit der der Strombalken gegen die Sammelschiene gedrückt wird, so dass ein guter elektrischer Kontakt zwischen dem Strombalken und der Sammelschiene gewährleistet ist.According to a preferred, because structurally particularly easy to implement embodiment of the invention, the second leg of the leg spring is simply on the end of the current bar facing away from the busbar receptacle or the end of the current bar presses against the second leg of the leg spring. The formation of a recess in the current bar can be dispensed with here. In this embodiment, the leg spring is clamped with its two legs between the abutment in the housing and the current bar, and the leg spring can also be secured in its position by corresponding ribs or retaining domes in the housing. If a busbar is plugged into the busbar receptacle, the current bar is pressed slightly out of its basic position in the direction of the leg spring, as a result of which the leg spring is compressed somewhat against its spring force. The force with which the current bar is pressed against the busbar then results from the spring force of the leg spring, so that good electrical contact between the current bar and the busbar is ensured.

Als Leiteranschlusselement, das im Gehäuse der Anschlussklemme angeordnet ist, kann grundsätzlich nahezu jede bekannte Art von Anschlusselementen, wie beispielsweise Schraubanschlüsse oder Zugfedern verwendet werden. Besonders bevorzugt wird bei der erfindungsgemäßen Anschlussklemme als Leiteranschlusselement jedoch eine Schenkelfeder verwendet, die einen Anlageschenkel und einen Klemmschenkel aufweist, wobei der Klemmschenkel zusammen mit dem Strombalken eine Federkraftklemmstelle für den anzuschließenden, abisolierten Leiter bildet. Mit einer derartigen U-förmigen oder V-förmigen Schenkelfeder kann ein starrer Leiter oder ein mit einer Aderendhülse versehener Leiter direkt, d. h. ohne dass die Klemmstelle vorher mit einem Werkzeug geöffnet werden muss, in die Klemmstelle eingesteckt werden. Die Schenkelfeder wirkt dabei als Druckfeder, die den anzuschließenden Leiter mit dem Klemmschenkel gegen den Strombalken drückt.In principle, almost any known type of connection element, such as screw connections or tension springs, can be used as the conductor connection element which is arranged in the housing of the connection terminal. In the connection terminal according to the invention, however, a leg spring is particularly preferably used as the conductor connection element, which has a contact leg and a clamping leg, the clamping leg together with the current bar forming a spring-loaded clamping point for the stripped conductor to be connected. With such a U-shaped or V-shaped leg spring, a rigid conductor or a conductor provided with a ferrule can be inserted directly into the terminal point, ie without the terminal point having to be opened beforehand with a tool. The leg spring acts as a compression spring which presses the conductor to be connected with the clamping leg against the current bar.

Zum Lösen eines angeschlossenen Leiters aus der Klemmstelle muss der Klemmschenkel der Schenkelfeder ausgelenkt werden, wozu im Gehäuse zusätzlich zur Leitereinführungsöffnung eine Betätigungsöffnung zum Einstecken der Spitze eines Werkzeugs, beispielsweise eines Schraubendrehers, ausgebildet sein kann. Gemäß einer bevorzugten Ausführungsform der erfindungsgemäßen Anschlussklemme ist anstelle einer Betätigungsöffnung für ein Werkzeug ein Betätigungsdrücker verschiebbar im Gehäuse angeordnet. Der Betätigungsdrücker kann dabei aus einer ersten Position, in der der Klemmschenkel der Schenkelfeder nicht ausgelenkt ist, in eine zweite Position verschoben werden, in der der Klemmschenkel durch die Spitze des Betätigungsdrückers ausgelenkt ist, so dass ein angeschlossener elektrischer Leiter aus der Klemmstelle und damit auch aus der Leitereinführungsöffnung herausgezogen werden kann.To release a connected conductor from the clamping point, the clamping leg of the leg spring must be deflected, for which purpose an actuating opening for inserting the tip of a tool, for example a screwdriver, can be formed in the housing in addition to the conductor insertion opening. According to a preferred embodiment of the connection terminal according to the invention, instead of an actuation opening for a tool, an actuation lever is arranged displaceably in the housing. The actuating pusher can be moved from a first position in which the clamping leg of the leg spring is not deflected into a second position in which the clamping leg is deflected by the tip of the operating pusher, so that a connected electrical conductor out of the clamping point and thus also can be pulled out of the conductor entry opening.

Zur Halterung und Positionierung der Sammelschiene in der Sammelschienenaufnahme weist die erfindungsgemäße Anschlussklemme vorzugsweise einen Klemmhebel auf, der auf der dem Strombalken gegenüberliegenden Seite der Sammelschienenaufnahme im Gehäuse drehbar gelagert ist. Der Klemmhebel weist mindestens eine in die Sammelschienenaufnahme hineinragende Klemmnase auf, die bei einer in der Sammelschienenaufnahme angeordneten Sammelschiene an der dem Strombalken abgewandten Seite der Sammelschiene an dieser anliegt. Eine in der Sammelschienenaufnahme angeodnete Sammelschiene wird dabei durch den Klemmhebel gegen den Strombalken gedrückt und zwischen dem Strombalken und der Klemmnase des Klemmhebels eingeklemmt, so dass die Sammelschiene gleichzeitig auch in der Sammelschienenaufnahme gehalten wird.To hold and position the busbar in the busbar receptacle, the connection terminal according to the invention preferably has a clamping lever which is rotatably mounted in the housing on the side of the busbar receptacle opposite the current bar. The clamping lever has at least one clamping nose which protrudes into the busbar receptacle and, in the case of a busbar arranged in the busbar receptacle, rests against the busbar on the side of the busbar facing away from the current bar. A busbar arranged in the busbar receptacle is pressed against the current bar by the clamping lever and clamped between the current bar and the clamping lug of the clamping lever, so that the busbar is also held in the busbar receptacle at the same time.

Zusätzlich zur mindestens einen Klemmnase weist der Klemmhebel vorzugsweise noch einen Betätigungsvorsprung auf, dessen freies Ende einen größeren Abstand vom Drehpunkt des Klemmhebels aufweist als die Klemmnase, so dass der Betätigungsvorsprung - bei nicht eingeführter Sammelschiene - weiter in die Sammelschienenaufnahme hineinragt als die Klemmnase. Beim Aufstecken der Anschlussklemme mit der Sammelschienenaufnahme auf eine Sammelschiene bzw. beim Einstecken der Sammelschiene in die Sammelschienenaufnahme der Anschlussklemme wird dadurch automatisch der Klemmhebel verschwenkt, bis die Sammelschiene vollständig in der Sammelschienenaufnahme angeordnet ist, und die Sammelschiene zwischen der Klemmnase und dem Strombalken, der durch die Kraft des Federelements gegen die Sammelschiene gedrückt wird, eingeklemmt ist.In addition to the at least one clamping lug, the clamping lever preferably also has an actuating projection, the free end of which is at a greater distance from the pivot point of the clamping lever than the clamping lug, so that the actuating projection - when the busbar is not inserted - protrudes further into the busbar receptacle than the clamping lug. When the connection terminal with the busbar receptacle is plugged onto a busbar or when the busbar is inserted into the busbar receptacle of the connection terminal, the clamping lever is thereby automatically pivoted until the busbar is completely in the busbar receptacle is arranged, and the busbar is clamped between the clamping lug and the current bar, which is pressed against the busbar by the force of the spring element.

Um eine sicher Befestigung einer Sammelschiene in der Sammelschienenaufnahme zu gewährleisten und so ein ungewolltes Abziehen einer erfindungsgemäßen Anschlussklemme von der Sammelschiene möglichst zu verhindern, kann eine zusätzliche Fixierung vorgesehen sein. Die Fixierung wird gemäß einer bevorzugten Ausgestaltung der Erfindung durch ein weiteres Federelement realisiert, das mindestens einen Schenkel aufweist und derart im Gehäuse angeordnet ist, dass das freie Ende des Schenkels in die Sammelschienenaufnahme hineinragt, wenn keine Sammelschiene in der Sammelschienenaufnahme angeordnet ist. Wird eine Sammelschiene in die Aufnahme eingeführt, so wird das Federelement gegen seine Federkraft ausgelenkt, wobei das freie Ende des Schenkels des Federelements unter einem spitzen Winkel an der Sammelschiene anliegt. Eine in die Sammelschienenaufnahme eingebrachte Sammelschiene wird somit durch Selbsthemmung gegen ein ungewolltes Abziehen der Anschlussklemme von der Sammelschiene entgegengesetzt zur Aufsteckrichtung gesichert.In order to ensure that a busbar is securely fastened in the busbar receptacle and thus as far as possible to prevent an unintentional pulling off of a connection terminal according to the invention from the busbar, an additional fixation can be provided. The fixation is realized according to a preferred embodiment of the invention by a further spring element which has at least one leg and is arranged in the housing such that the free end of the leg protrudes into the busbar receptacle when no busbar is arranged in the busbar receptacle. If a busbar is inserted into the receptacle, the spring element is deflected against its spring force, the free end of the leg of the spring element resting against the busbar at an acute angle. A busbar introduced into the busbar receptacle is thus secured by self-locking against inadvertent removal of the connection terminal from the busbar in the opposite direction to the attachment direction.

Die Verwendung eines Federelements für die Fixierung der Sammelschiene hat dabei den Vorteil, dass das Federelement zum Einen das Einführen der Sammelschiene in die Sammelschienenaufnahme nicht merklich behindert, zum Anderen die Fixierung nach dem Einführen der Sammelschiene wirksam ist, ohne dass es einer Betätigung durch den Benutzer bedarf. Vorzugsweise ist auch das weitere Federelement als Schenkelfeder ausgebildet, die zwei Schenkel aufweist, wobei sich der zweite Schenkel, der nicht mit der Sammelschiene in Berührung steht, als Anlageschenkel an einem Widerlager im Gehäuse abstützt.The use of a spring element for fixing the busbar has the advantage that, on the one hand, the spring element does not noticeably hinder the introduction of the busbar into the busbar receptacle, and on the other hand, the fixation is effective after the busbar has been inserted without the user being actuated requirement. The further spring element is preferably also designed as a leg spring which has two legs, the second leg, which is not in contact with the busbar, being supported as a bearing leg on an abutment in the housing.

Damit auch bei der bevorzugten Ausgestaltung der Anschlussklemme mit einer weiteren, der Fixierung der Sammelschiene dienenden Schenkelfeder die Anschlussklemme von der Sammelschiene abgehoben bzw. die Sammelschiene aus der Sammelschienenaufnahme herausgezogen werden kann, weist die Anschlussklemme gemäß einer weiteren vorteilhaften Ausgestaltung ein Entriegelungselement auf. Das Entriegelungselement ist dabei beweglich am oder im Gehäuse angeordnet, so dass es aus einer Grundstellung in eine Entriegelungsstellung verbracht werden kann. In der Entriegelungsstellung wird der Schenkel des Federelements, der der Sammelschiene zugewandt ist und die Sammelschiene in ihrer Position fixiert, durch das Entriegelungselement so ausgelenkt, dass das freie Ende des Schenkels nicht mehr an der Seite der Sammelschiene anliegt. Die Anschlussklemme kann dann entgegen der Aufsteckrichtung von der Sammelschiene abgehoben bzw. die Sammelschiene entgegen der Einsteckrichtung aus der Sammelschienenaufnahme herausgezogen werden.So that in the preferred embodiment of the connection terminal with a further leg spring serving to fix the busbar, the connection terminal can be lifted off the busbar or the busbar can be pulled out of the busbar receptacle, the connection terminal has an unlocking element according to a further advantageous embodiment. The unlocking element is movable on the or arranged in the housing so that it can be brought from a basic position into an unlocked position. In the unlocked position, the leg of the spring element that faces the busbar and fixes the busbar in its position is deflected by the unlocking element so that the free end of the leg no longer rests on the side of the busbar. The connection terminal can then be lifted off the busbar counter to the plug-on direction or the busbar can be pulled out of the busbar receptacle counter to the plug-in direction.

Grundsätzlich könnte das Entriegelungselement - ähnlich wie der Betätigungsdrücker - verschiebbar im Gehäuse angeordnet sein. Vorzugsweise ist das Entriegelungselement jedoch als Hebel ausgebildet, der über ein Scharnier am Gehäuse verschwenkbar befestigt ist, wobei das Entriegelungselement eine Grifffläche zur Betätigung mit einem Finger aufweist. Dadurch ist die Betätigung des Entriegelungselements von einem Monteur sehr einfach durchführbar, indem er beispielsweise beim Abheben der Anschlussklemme von der Sammelschiene einfach mit einem Finger auf die Grifffläche des Hebels drückt, wodurch der Hebel verschwenkt wird, so dass der Schenkel des Federelements ausgelenkt und dadurch die Verriegelung gelöst wird.In principle, the unlocking element - similar to the actuating lever - could be arranged displaceably in the housing. Preferably, however, the unlocking element is designed as a lever which is pivotably attached to the housing via a hinge, the unlocking element having a gripping surface for actuation with a finger. As a result, the actuation of the unlocking element can be carried out very easily by a fitter, for example by simply pressing with a finger on the gripping surface of the lever when lifting the connection terminal from the busbar, whereby the lever is pivoted so that the leg of the spring element is deflected and thereby the Lock is released.

Im Einzelnen gibt es nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße Anschlussklemme auszugestalten und weiterzubilden. Dazu wird verwiesen sowohl auf die dem Patentanspruch 1 nachgeordneten Patentansprüche als auch auf die nachfolgende Beschreibung eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung.

Die Figuren zeigen ein bevorzugtes Ausführungsbeispiel einer erfindungsgemäßen Anschlussklemme 1 zum Verbinden eines - hier nicht dargestellten - elektrischen Leiters mit einer Sammelschiene 2. Während in Fig. 1 die Anschlussklemme 1 ohne Sammelschiene 2 dargestellt ist, zeigen die Fig. 2, 3 und 4 die Anschlussklemme 1 mit zwei unterschiedlich dicken Sammelschienen 2, nämlich einmal mit einer ersten, dünneren Sammelschiene 2 (Fig. 2 und 4) und einmal mit einer zweiten, dickeren Sammelschiene 2 (Fig. 3). In Fig. 4 ist die Anschlussklemme 1 mit der dünneren Sammelschiene 2 gemäß Fig. 2 dargestellt, wobei im Unterschied zur Fig. 2 die zwischen der Anschlussklemme 1 und der Sammelschiene 2 ausgebildete Fixierung gelöst ist, so dass die Anschlussklemme 1 von der Sammelschiene 2 entgegen der Aufsteckrichtung A abgehoben werden kann.The figures show a preferred exemplary embodiment of a connection terminal 1 according to the invention for connecting an electrical conductor - not shown here - to a busbar 2. While in FIG Fig. 1 the connection terminal 1 is shown without busbar 2, show the Fig. 2 , 3 and 4th the connection terminal 1 with two busbars 2 of different thicknesses, namely one with a first, thinner busbar 2 ( Fig. 2 and 4th ) and once with a second, thicker busbar 2 ( Fig. 3 ). In Fig. 4 is the terminal 1 with the thinner busbar 2 according to Fig. 2 shown, whereby in contrast to Fig. 2 the fixing formed between the connection terminal 1 and the busbar 2 is released, so that the connection terminal 1 can be lifted off the busbar 2 in the opposite direction to the attachment direction A.

Die erfindungsgemäße Anschlussklemme 1 weist ein Gehäuse 3 auf, in dem ein Leiteranschlusselement 4 in Form einer Schenkelfeder und ein L-förmiger Strombalken 5 angeordnet sind. Zum Einführen eines anzuschließenden Leiters in die Klemmstelle ist in dem Gehäuse 3 eine Leitereinführungsöffnung 6 ausgebildet. Darüber hinaus weist das in der Regel aus Kunststoff bestehende Gehäuse 3 noch eine Sammelschienenaufnahme 7 auf, die einseitig offen ist, so dass die Anschlussklemme 1 auf eine ggf. bereits montierte Sammelschiene 2 mit der Sammelschienenaufnahme 7 in Aufsteckrichtung A aufgesteckt bzw. aufgesetzt werden kann. Ist die Anschlussklemme 1 bereits montiert, so besteht die Möglichkeit, eine Sammelschiene 2 aus der zur Aufsteckrichtung A entgegengesetzten Richtung in die Sammelschienenaufnahme 7 einzustecken.The connection terminal 1 according to the invention has a housing 3 in which a conductor connection element 4 in the form of a leg spring and an L-shaped current bar 5 are arranged. To insert a conductor to be connected into the terminal point, a conductor insertion opening 6 is formed in the housing 3. In addition, the housing 3, which is usually made of plastic, also has a busbar receptacle 7, which is open on one side, so that the connection terminal 1 can be plugged or placed on a busbar 2 with the busbar receptacle 7, which may have already been installed, in the plug-in direction A. If the connection terminal 1 has already been installed, there is the possibility of inserting a busbar 2 into the busbar receptacle 7 from the direction opposite to the direction of attachment A.

Wie aus einem Vergleich der Fig. 1 mit den Fig. 2 und 3 ersichtlich ist, ist bei der erfindungsgemäßen Anschlussklemme 1 der Strombalken 5 - senkrecht zur Aufsteckrichtung A - verschiebbar im Gehäuse 3 gelagert. Der Strombalken 5 wird dabei von einem Federelement 8 mit einer Kraft in Richtung der Sammelschienenaufnahme 7 bzw. in Richtung einer in der Sammelschienenaufnahme 7 angeordneten Sammelschiene 2 gedrückt, so dass gewährleistet ist, dass stets eine ausreichende Kontaktkraft und damit ein guter elektrischer Kontakt zwischen dem Strombalken 5 und der Sammelschiene 2 besteht.As from a comparison of the Fig. 1 with the Fig. 2 and 3 As can be seen, in the connection terminal 1 according to the invention, the current bar 5 is mounted in the housing 3 so as to be displaceable - perpendicular to the attachment direction A. The current bar 5 is pressed by a spring element 8 with a force in the direction of the busbar receptacle 7 or in the direction of a busbar 2 arranged in the busbar receptacle 7, so that it is ensured that there is always a sufficient contact force and thus a good electrical contact between the current bar 5 and the busbar 2 consists.

Bei der Darstellung gemäß Fig. 1, bei der keine Sammelschiene 2 in der Sammelschienenaufnahme 7 angeordnet ist, ist der L-förmige Strombalken 5 durch die Kraft des Federelements 8 bis zu dem im Gehäuse 3 ausgebildeten Anschlag 9 in Richtung der Sammelschienenaufnahme 7 - in der Darstellung nach links - verschoben. Im Unterschied dazu ist bei den Darstellungen gemäß den Fig. 2 bis 4, bei den jeweils eine Sammelschiene 2 in der Sammelschienenaufnahme 7 angeordnet ist, der Strombalken 5 durch die Sammelschiene 2 entgegen der Federkraft des Federelements 8 etwas von dem Anschlag 9 - in den Darstellungen nach rechts - weggedrückt, wodurch die gewünschte definierte Kontaktkraft zwischen der Sammelschiene 2 und dem Strombalken 5 gewährleistet ist.When presented in accordance with Fig. 1 , in which no busbar 2 is arranged in the busbar receptacle 7, the L-shaped current bar 5 is displaced by the force of the spring element 8 up to the stop 9 formed in the housing 3 in the direction of the busbar receptacle 7 - to the left in the illustration. In contrast to this, in the representations according to Figs. 2 to 4 , in each of which a busbar 2 is arranged in the busbar receptacle 7, the current bar 5 by the busbar 2 against the spring force of the spring element 8 slightly pushed away from the stop 9 - in the illustrations to the right -, whereby the desired defined contact force between the busbar 2 and the current bar 5 is guaranteed.

Bei dem in den Figuren dargestellten bevorzugten Ausführungsbeispiel der Anschlussklemme 1 ist das Federelement 8, das den Strombalken 5 gegen die Sammelschiene 2 drückt, als Schenkelfeder ausgebildet, die zwei Schenkel 10, 11 aufweist. Der erste Schenkel 10 dient dabei als Anlageschenkel, der sich an einem Widerlager 12 im Gehäuse 3 abstützt, während der zweite Schenkel 11 mit dem Strombalken 5 in Kontakt steht. Dazu liegt der zweite Schenkel 11 an dem der Sammelschienenaufnahme 7 abgewandten Ende 13 des Strombalkens 5 an. Das Federelement 8 ist somit mit seinen beiden Schenkeln 10, 11 zwischen dem Widerlager 12 im Gehäuse 3 und dem Ende 13 des Strombalkens 5 eingeklemmt. Die Montage von Strombalken 5 und Federelement 8 in das Gehäuse 3 ist dabei sehr einfach, da der Strombalken 5 und das Federelement 8 einzeln in das Gehäuse 3 eingesetzt werden können.In the preferred exemplary embodiment of the connection terminal 1 shown in the figures, the spring element 8, which presses the current bar 5 against the busbar 2, is designed as a leg spring which has two legs 10, 11. The first leg 10 serves as a contact leg which is supported on an abutment 12 in the housing 3, while the second leg 11 is in contact with the current bar 5. For this purpose, the second leg 11 rests against the end 13 of the current bar 5 facing away from the busbar receptacle 7. The spring element 8 is thus clamped with its two legs 10, 11 between the abutment 12 in the housing 3 and the end 13 of the current bar 5. The assembly of the current bar 5 and spring element 8 in the housing 3 is very simple, since the current bar 5 and the spring element 8 can be inserted individually into the housing 3.

Ebenso wie das Federelement 8 ist bei dem dargestellten Ausführungsbeispiel der Anschlussklemme 1 auch das Leiteranschlusselement 4 als Schenkelfeder ausgebildet, die zwei Schenkel aufweist, nämlich einen Anlageschenkel 14 und einen Klemmschenkel 15. Ein durch die Leitereinführungsöffnung 6 in das Gehäuse 3 eingeführter abisolierter elektrischer Leiter wird dann durch den Klemmschenkel 15 gegen den Schenkel 16 des Strombalkens 5 gedrückt, der auch an einer eingeführten Sammelschiene 2 anliegt. Der Klemmschenkel 15 bildet somit zusammen mit dem Schenkel 16 des Strombalkens 5 eine Federkraftklemmstelle für den anzuschließenden Leiter.Like the spring element 8, in the illustrated embodiment of the connection terminal 1, the conductor connection element 4 is also designed as a leg spring which has two legs, namely a contact leg 14 and a clamping leg 15. A stripped electrical conductor inserted through the conductor insertion opening 6 into the housing 3 is then through the clamping leg 15 is pressed against the leg 16 of the current bar 5, which is also in contact with an inserted busbar 2. The clamping leg 15 thus forms, together with the leg 16 of the current bar 5, a spring force clamping point for the conductor to be connected.

Um einen angeschlossenen Leiter wieder aus der Anschlussklemme 1 herausziehen zu können, muss die Klemmstelle geöffnet werden, wozu der Klemmschenkel 15 ausgelenkt und damit von dem angeschlossenen Leiter abgehoben werden muss. Hierzu weist die Anschlussklemme 1 einen im Gehäuse 3 verschiebbar angeordneten Betätigungsdrücker 17 auf, der aus einer ersten, in den Figuren dargestellten Position, in eine zweite Position innerhalb des Gehäuses 3 verschoben werden kann. Während der Klemmschenkel 15 in der ersten Position des Betätigungsdruckers 17 nicht ausgelenkt ist, ist der Klemmschenkel 15 in der zweiten Position des Betätigungsdrückers 17 soweit ausgelenkt, dass ein angeschlossener Leiter nicht mehr in der Klemmstelle festgeklemmt ist und somit durch die Leitereinführungsöffnung 6 aus der Anschlussklemme 1 herausgezogen werden kann.In order to be able to pull a connected conductor out of the connection terminal 1 again, the clamping point must be opened, for which purpose the clamping leg 15 must be deflected and thus lifted off the connected conductor. For this purpose, the connecting terminal 1 has an actuating lever 17 which is arranged displaceably in the housing 3 and which can be displaced from a first position shown in the figures into a second position within the housing 3. While the clamping leg 15 is not deflected in the first position of the actuating printer 17, the clamping leg 15 is deflected in the second position of the actuating lever 17 to such an extent that a connected conductor is no longer clamped in the clamping point and thus out of the connection terminal 1 through the conductor entry opening 6 can be pulled out.

Auf der dem Strombalken 5 gegenüberliegenden Seite der Sammelschienenaufnahme 7 ist ein Klemmhebel 18 drehbar im Gehäuse 3 gelagert, durch den die Sammelschiene 2 in der Sammelschienenaufnahme 7 gehalten und insbesondere in Richtung des Strombalkens 5 gedrückt wird. Der Klemmhebel 18 dient somit insbesondere zur richtigen Positionierung der Sammelschiene 2 am Strombalken 5 bzw. dessen erstem Schenkel 16. Gemäß der bevorzugten Ausgestaltung weist der Klemmheben 18 zwei in die Sammelschienenaufnahme 7 hineinragende Klemmnasen 19, 20 und einen Betätigungsvorsprung 21 auf. Je nach Dicke der Sammelschiene kontaktiert dabei entweder die erste Klemmnase 19 (Fig. 2 und 4) oder die zweite Klemmnase 20 (Fig. 3) die Sammelschiene 2.On the side of the busbar receptacle 7 opposite the current bar 5, a clamping lever 18 is rotatably mounted in the housing 3, by means of which the busbar 2 is held in the busbar receptacle 7 and, in particular, is pressed in the direction of the current bar 5. The clamping lever 18 thus serves in particular for the correct positioning of the busbar 2 on the current bar 5 or its first leg 16. According to the preferred embodiment, the clamping lever 18 has two clamping lugs 19, 20 protruding into the busbar receptacle 7 and an actuating projection 21. Depending on the thickness of the busbar, either the first clamping lug 19 ( Fig. 2 and 4th ) or the second clamping lug 20 ( Fig. 3 ) the busbar 2.

Wie insbesondere aus den Fig. 1a und 1b ersichtlich ist, weist das freie Ende des Betätigungsvorsprungs 21 einen größeren Abstand vom Drehpunkt des Klemmhebels 18 auf als die Klemmnase 19 und - einen deutlich größeren Abstand - als die Klemmnase 20. Der Betätigungsvorsprung 21 ragt somit bei freier Sammelschienenaufnahme 7 am weitesten in die Sammelschienenaufnahme 7 hinein, so dass beim Aufstecken des Gehäuses 3 auf eine Sammelschiene 2 die Sammelschiene 2 zunächst am Betätigungsvorsprung 21 anstößt und dadurch den Klemmhebel 18 entgegengesetzt zum Uhrzeigersinn verschwenkt, bis das Gehäuse 3 vollständig auf der Sammelschiene 2 aufgesetzt ist, so dass dann gemäß Fig. 2 die erste Klemmnase 19 bzw. bei dem Ausführungsbeispiel gemäß Fig. 3 die zweite Klemmnase 20 an der Sammelschiene 2 anliegt und diese dadurch gegen den Strombalken 5 drückt.As in particular from the Figures 1a and 1b As can be seen, the free end of the actuating projection 21 is at a greater distance from the pivot point of the clamping lever 18 than the clamping lug 19 and - a significantly greater distance - than the clamping lug 20. The actuating projection 21 thus protrudes farthest into the busbar receptacle 7 when the busbar receptacle 7 is free into it, so that when the housing 3 is plugged onto a busbar 2, the busbar 2 first abuts the actuating projection 21 and thereby pivots the clamping lever 18 counterclockwise until the housing 3 is completely placed on the busbar 2, so that according to FIG Fig. 2 the first clamping lug 19 or in the embodiment according to Fig. 3 the second clamping lug 20 rests against the busbar 2 and thereby presses it against the current bar 5.

Bei der in den Figuren dargestellten bevorzugten Ausgestaltung der erfindungsgemäßen Anschlussklemme 1 ist neben dem den Strombalken 5 gegen eine Sammelschiene 2 drückenden Federelement 8 noch ein weiteres, ebenfalls als Schenkelfeder ausgebildetes Federelement 22 im Gehäuse 3 angeordnet. Insgesamt sind somit drei Schenkelfedern im Gehäuse 3 angeordnet, die alle drei unterschiedlichen Funktionen wahrnehmen. Das Federelement 22 ist dabei derart im Gehäuse 3 unterhalb des Strombalkens 5 angeordnet, dass der erste Schenkel 23 des Federelements mit seinem freien Ende 24 in die Sammelschienenaufnahme 7 hineinragt, wenn dort keine Sammelschiene 2 angeordnet ist (Fig. 1).In the preferred embodiment of the connection terminal 1 according to the invention shown in the figures, a further spring element 22, also designed as a leg spring, is arranged in the housing 3 in addition to the spring element 8 pressing the current bar 5 against a busbar 2. A total of three leg springs are thus arranged in the housing 3, all of which perform three different functions. The spring element 22 is arranged in the housing 3 below the current bar 5 in such a way that the first leg 23 of the spring element protrudes with its free end 24 into the busbar receptacle 7 if no busbar 2 is arranged there ( Fig. 1 ).

Wird das Gehäuse 3 der Anschlussklemme 1 auf eine Sammelschiene 2 aufgesteckt, so wird der Schenkel 23 entgegen der Federkraft des Federelements 22 ausgelenkt, so dass die Sammelschiene 2 an dem freien Ende 24 des Schenkels 23 vorbei gleiten kann. Bei vollständig aufgestecktem Gehäuse 3 liegt das freie Ende 24 des Schenkels 23 unter einem spitzen Winkel α an der Sammelschiene 2 an. Hierdurch wird die Sammelschiene 2 in der Sammelschienenaufnahme 7 durch die Selbsthemmung fixiert und ein ungewolltes Abziehen des Gehäuses 3 von der Sammelschiene 2 bzw. ein ungewolltes Herausziehen der Sammelschiene 2 aus der Sammelschienenaufnahme 7 im Gehäuse 3 verhindert. Der zweite Schenkel 25 des Federelements 22 dient wiederum als Anlageschenkel, wozu sich der Schenkel 25 an einem entsprechenden Widerlager 26 im Gehäuse 3 abstützt.If the housing 3 of the connection terminal 1 is plugged onto a busbar 2, the leg 23 is deflected against the spring force of the spring element 22, so that the busbar 2 can slide past the free end 24 of the leg 23. When the housing 3 is fully attached, the free end 24 of the leg 23 rests against the busbar 2 at an acute angle α. As a result, the busbar 2 is fixed in the busbar receptacle 7 by the self-locking and an unintentional pulling of the housing 3 from the busbar 2 or an unintentional pulling of the busbar 2 out of the busbar receptacle 7 in the housing 3 is prevented. The second leg 25 of the spring element 22 in turn serves as a contact leg, for which the leg 25 is supported on a corresponding abutment 26 in the housing 3.

Soll die Anschlussklemme 1 gewollt entgegengesetzt zur Aufsteckrichtung A von einer in der Sammelschienenaufnahme 7 angeordneten Sammelschiene 2 abgehoben werden, so muss der Schenkel 23 des Federelements 22 entgegengesetzt zur Federkraft des Federelements 22 ausgelenkt werden. Hierzu ist ein als Hebel ausgebildetes Entriegelungselement 27 vorgesehen, das über ein flexibles Scharnier 28 am Gehäuse 3 beweglich angeordnet ist. Zur Betätigung des Entriegelungselements 27 muss der Benutzer nur mit einem Finger auf die Grifffläche 29 drücken, wodurch die Betätigungsnase 30 des Entriegelungselements 27 gegen den Schenkel 23 des Federelements 22 drückt und diesen dadurch von der Sammelschiene 2 abhebt, wie dies in Fig. 4 dargestellt ist. Die Anschlussklemme 1 kann dann ohne Weiteres entgegengesetzt zur Aufsteckrichtung A von der Sammelschiene 2 abgehoben bzw. die Sammelschiene 2 - nach unten - aus der Sammelschienenaufnahme 7 im Gehäuse 3 herausgezogen werden.If the connection terminal 1 is to be lifted from a busbar 2 arranged in the busbar receptacle 7 in the opposite direction to the attachment direction A, the leg 23 of the spring element 22 must be deflected counter to the spring force of the spring element 22. For this purpose, an unlocking element 27 designed as a lever is provided, which has a flexible Hinge 28 is movably arranged on housing 3. To actuate the unlocking element 27, the user only has to press one finger on the gripping surface 29, whereby the actuating lug 30 of the unlocking element 27 presses against the leg 23 of the spring element 22 and thereby lifts it off the busbar 2, as shown in FIG Fig. 4 is shown. The connection terminal 1 can then easily be lifted off the busbar 2 in the opposite direction to the attachment direction A or the busbar 2 can be pulled - downwards - out of the busbar receptacle 7 in the housing 3.
