Definitions

  • the invention relates to a conductor connection terminal according to the preamble of claim 1.
  • Such a conductor connection terminal is from the EN 10 2013 107 292 A1 known. From the US9,525,219 B2 A conductor terminal with spring clamp connection is known, which has an internal busbar. From the DE 201 20 811 U1 A busbar terminal is known. From the US 2015/0372402 A1 A conductor terminal with spring clamp connections and a continuous internal busbar is known. JP 2004 165045 A Another busbar connection terminal is known.
  • the invention is based on the object of further optimizing such a conductor connection terminal.
  • the conductor connection terminal serves to connect an electrical conductor by means of spring clamping, wherein the conductor connection terminal is designed to be plugged onto a busbar, wherein the conductor connection terminal has at least one spring clamp connection with a clamping spring for clamping the electrical conductor, a housing at least partially surrounding the spring clamp connection with a conductor insertion opening and a pivotably mounted actuating lever which is designed to actuate at least part of the clamping spring, wherein a receiving space is provided in the housing for receiving at least a section of the busbar onto which the conductor connection terminal can be plugged.
  • the conductor connection terminal according to the invention can be realized with a simple and compact structure. A simple and safe lever operation with secure clamping can be achieved.
  • the conductor connection terminal allows easy snapping or other attachment to the busbar.
  • the electrical conductor to be connected can be introduced into the housing in a conductor insertion direction through the conductor insertion opening and guided to a terminal point of the spring-loaded terminal connection.
  • a conductor insertion channel can be connected to the conductor insertion opening within the housing.
  • the conductor insertion channel and the receiving space are arranged in such a way that they merge into one another, so that a busbar received in the receiving space at least partially protrudes into the conductor insertion channel.
  • the actuating lever adjoins the receiving space of the busbar or protrudes into the receiving space of the busbar.
  • the actuating lever can use the surface of the busbar at least in part as a support and sliding surface during the pivoting movement.
  • the structure of the conductor connection terminal can therefore be simplified, since in particular the bearing of the actuating lever required for the pivoting movement requires less effort with regard to the structural design of the conductor connection terminal.
  • the actuating lever can be supported on the busbar accommodated in the receiving space, at least during a pivoting movement of the actuating lever.
  • the actuating lever can thus slide at least partially along the surface of the busbar during the pivoting movement.
  • the conductor connection terminal has positioning elements for positioning the busbar relative to the receiving space in an installation position in which the busbar is arranged obliquely relative to the conductor insertion direction.
  • the positioning elements determine a specific position of the section of the busbar present in the receiving space relative to the conductor insertion direction and and thus also defined with regard to the clamped-on electrical conductor.
  • the positioning elements can thus be used to fix the busbar in its installation position.
  • the electrical conductor is not arranged parallel to the busbar, but at a certain angle to it, for example at an acute angle.
  • the angle between the conductor insertion direction and the surface of the busbar facing the electrical conductor can, for example, be in the range of 5 to 45 degrees. This allows the electrical conductor to be clamped particularly reliably, whereby the section of the busbar located in the receiving space can be used to clamp the electrical conductor. By guiding the electrical conductor at an angle to the surface of the busbar, the electrical conductor does not come into contact with the busbar.
  • the positioning elements have one or more locking elements, by means of which the conductor connection terminal can be connected to the busbar in a locking manner.
  • the conductor connection terminal can in particular be designed in such a way that no positioning elements have to be separately operated manually in order to connect the conductor connection terminal to the busbar.
  • the housing of the conductor connection terminal can be designed as a housing consisting of one or more components, whereby the housing with its one or more components can be designed to be rigid overall. A joint for opening or closing the housing is not required.
  • the receiving space extends completely through the conductor connection terminal in a transverse direction that runs orthogonal to the conductor insertion direction.
  • the housing of the conductor connection terminal which can be designed as an insulating housing, for example, is thus open at the side in the area of the receiving space. Accordingly, the conductor connection terminal can also be plugged onto a busbar that has a relatively large longitudinal extension.
  • the clamping spring has a contact leg, a spring arch adjoining the contact leg, and a clamping leg adjoining the spring arch for clamping the electrical conductor.
  • the clamping spring can be supported by means of the contact leg on a part of the conductor connection terminal against the clamping force of the clamping leg.
  • the electrical conductor can be clamped by the clamping force of the clamping leg.
  • the conductor connection terminal can have, for example, a busbar against which the electrical conductor is pressed by means of the clamping leg, or an area of the surface of the busbar can be used to clamp the electrical conductor.
  • the clamping leg can act directly on the busbar, or via one or more other elements, for example a busbar and/or the clamped electrical conductor.
  • the conductor connection terminal has a holding frame on which the contact leg is held, e.g. by the contact leg being received, suspended or fixed there.
  • the holding frame can be designed as a metal part, for example.
  • the holding frame can have an opening surrounded by webs on the circumference, through which at least one free end of the electrical conductor to be clamped can be passed.
  • the contact leg can be suspended on the holding frame, for example, on the inner circumference of the opening.
  • the holding frame has a tension element or is coupled to a tension element.
  • the busbar in the receiving space can be supported on the tension element against a clamping force of the clamping leg acting on the busbar.
  • the tension element which can be designed as a pull rod, for example, can transfer a pure tensile force from the busbar to the fastening point of the contact leg.
  • the spring-loaded clamp connection can be held self-supportingly on the busbar via the tension element. In such a self-supporting system, no or only negligible forces of the clamping spring are transferred to the housing. This makes it possible in particular to create a closed Force flow must be created between the tension element, the holding frame and the busbar.
  • the free end of the clamping leg is positioned in such a way that a clamping point for clamping the electrical conductor is formed between a free end and a surface of a busbar located in the receiving space facing the clamping leg.
  • the busbar can be used as a clamping surface for the electrical conductor.
  • the conductor connection terminal can therefore be designed without its own busbar, i.e. without a busbar. This can further simplify the structure of the conductor connection terminal.
  • an electrical conductor clamped to the clamping point can be clamped between the free end of the clamping leg and a corner edge of the busbar.
  • the receiving space can have positioning elements which position the busbar received in the receiving space in such a way that a corner edge is positioned towards the free end of the clamping leg in such a way that a clamped electrical conductor can be clamped between the free end and the corner edge.
  • the clamping leg can have a clamping edge at its free end. This further improves the reliability of the clamping of the electrical conductor.
  • the housing has an insertion opening through which a section of the busbar can be inserted into the receiving space of the conductor connection terminal.
  • the insertion opening can be arranged on the same side of the housing as the conductor insertion opening or on a side of the housing facing away from an actuating side of the conductor connection terminal.
  • the actuating side of the conductor connection terminal is a side on which a manual actuating element of the operating lever is accessible for manual operation. This allows a particularly easy insertion of the section of the busbar into the receiving space or a simple plugging of the conductor connection terminal onto the busbar.
  • the actuating lever is U-shaped when viewed in the conductor insertion direction, with a first and a second bearing disc, which are connected to one another via a connecting region of the actuating lever, with a gap between the first and the second bearing disc for the electrical conductor to be clamped through.
  • the actuating lever can transmit large actuating forces to the clamping spring with a compact design.
  • the conductor connection terminal can be designed to be very compact overall, since the gap between the bearing discs can be used to guide the electrical conductor through.
  • the first and second bearing discs can, for example, be supported on the surface of the busbar and slide thereon when a pivoting movement of the operating lever is carried out.
  • the U-shaped part of the actuating lever has an open side which is positioned such that it can be covered by the surface of the busbar accommodated in the receiving space.
  • the open side of the U-shape can thus be closed by the busbar accommodated in the receiving space.
  • the first and second bearing discs form a guide for the electrical conductor guided through the gap in each actuation position of the actuation lever. Accordingly, a guide for the electrical conductor is already provided by the actuation lever. The guidance can be ensured in every operating state of the conductor connection terminal, in particular in every pivot position of the actuation lever, by the first and second bearing discs.
  • the Conductor connection terminal can have additional conductor guiding elements, as explained below.
  • the conductor connection terminal has only one spring for each spring clamp connection, namely the clamping spring of the spring clamp connection.
  • the conductor connection terminal is simple and has only a few components. This simplifies both the manufacture and the assembly of the conductor connection terminal.
  • the clamping spring is essentially V-shaped.
  • the spring-loaded clamp connection can be designed as a direct corner connection.
  • an electrical conductor if it is sufficiently rigid (for example a single-wire conductor), can be inserted directly into the clamping point without operating the operating lever and can be clamped in place using the clamping leg.
  • the operating lever only needs to be operated to remove the clamped electrical conductor from the clamping point.
  • the operating lever can, for example, have an open position and a closed position.
  • the clamping point In the open position, the clamping point is open, i.e. the clamping leg is far enough away from the counterpart used for clamping (e.g. busbar or busbar) that an electrical conductor can be inserted into or removed from the clamping point without the need for force.
  • the clamping leg In the closed position, the clamping leg is effective in clamping the electrical conductor to the clamping point.
  • the operating lever can be mounted in the conductor terminal in a movable and/or floating manner, particularly in the area of its bearing.
  • the operating lever can assume a slightly different position in the conductor terminal in the area of its bearing if no busbar is arranged in the receiving space, compared to the state of a busbar arranged in the receiving space.
  • the operating lever can be displaced by the busbar in the area of its bearing to a certain (usually relatively small) extent.
  • the indefinite term “a” is not to be understood as a number. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component”. If angles are given in degrees, these refer to a circular dimension of 360 degrees (360°).
  • the conductor connection terminal 1 shown has a housing 2, a clamping spring 4, an actuating lever 5 and a holding frame 6.
  • the housing 2 can, for example, be designed in two parts with a first housing component 20 and a second housing component 21.
  • the first and second housing components 20, 21 can be attached to one another via positioning elements, for example by locking them together.
  • the clamping spring 4 and the holding frame 6 are arranged in the area surrounded by the housing 2.
  • the Figure 1 additionally shows a busbar 3 to which the conductor connection terminal 1 is attached.
  • the housing 2 has a conductor receiving chamber 22, a conductor insertion opening 23, an insertion opening 24, a receiving space 25 for receiving a section of the busbar 3 and positioning elements 26, 27, 28 which serve to position the busbar 3 relative to the receiving space 25 in a defined installation position.
  • the conductor receiving chamber 22 can be formed, for example, by a part of the second housing component 21, the other mentioned elements of the housing 2 can be formed on the first housing component 20.
  • the conductor insertion opening 23 is located on a conductor insertion side 11 of the conductor connection terminal 1.
  • the conductor insertion opening 23 is followed in the interior of the housing 2 by a conductor insertion channel 98 which can, for example, be at least partially surrounded by walls of the housing 2.
  • An electrical conductor that is to be connected to the conductor connection terminal 1 can be guided in a conductor insertion direction L through the conductor insertion opening 23 to a terminal point explained below.
  • the insertion opening 24 is used to insert a section of the busbar 3 into the receiving space 25. If this section of the busbar 3 is completely inserted, the in Figure 1 shown state, in which the receiving space 25 is largely filled by this section of the busbar 3. As can be seen, the busbar 3 protrudes at least a little way into the conductor entry channel 98.
  • the positioning elements 26, 27 can be designed, for example, as mutually opposite sliding edges of the housing 2, on which the busbar is guided during its insertion through the insertion opening 24 into the receiving space 25 and is ultimately held in the installation position.
  • the positioning element 28 can be designed as a locking element that is arranged on a spring-loaded locking tongue of the housing 2. This locking tongue gives way slightly when the busbar 3 is inserted and then snaps back again when the installation position of the busbar 3 in the receiving space 25 is reached, whereby the busbar 3 is fixed in the receiving space 25 by locking.
  • the position of the busbar 3 can be fixed, for example, by the holding frame 6.
  • the clamping spring 4 has a contact leg 41, a spring arch 42 adjoining the contact leg 41 and a clamping leg 43 adjoining the spring arch 42.
  • the contact leg is fixed to the holding frame 6 via its free end 40 and supported there, for example by the free end 40 being suspended there behind a web 60 of the holding frame 6.
  • the web 60 can in this way form a first bearing 60 for receiving the contact leg 41.
  • the clamping leg 43 ends at a free end 44, on which a clamping edge can be present. By means of the free end 44 or the clamping edge, an electrical conductor can be clamped to a surface 30 of the busbar 3.
  • the clamping point of the spring force clamp connection realized in this way is thus formed between the free end 44 or the clamping edge of the clamping leg 43 and the surface 30 of the busbar 3.
  • the clamping point can be formed in particular with the aid of the corner edge 31 of the busbar 3.
  • the holding frame 6 has a recess 61.
  • An electrical conductor to be connected which is inserted through the conductor insertion opening 23, is first through the conductor insertion channel 98 adjoining the conductor insertion opening 23.
  • the electrical conductor is guided by bearing disks 52 arranged on the sides.
  • the clamping leg 43 and the surface 30 of the busbar 3 also play a role in guiding the conductor.
  • the electrical conductor can be inserted through the recess 61 into the conductor receiving space 22, which also forms an end stop to limit the depth of insertion of the electrical conductor.
  • the holding frame 6 is continued below the recess 61 by a tension element 62, behind which the busbar 3 is suspended.
  • the tension element 62 can, for example, end with a bent free end that forms a second bearing 99 on which the busbar 3 rests.
  • the clamping spring 4 transmits a clamping force directly or indirectly to the busbar 3 through the clamping leg 43.
  • the busbar 3 is supported against this clamping force by the tension element 62, which in turn is connected to the contact leg 41 via the holding frame 6. In this way, a self-supporting contact insert of the conductor connection terminal 1 is realized.
  • the actuating lever 5 is accessible for manual actuation on an actuating side 10 of the conductor connection terminal 1.
  • the actuating lever 5 has a manual actuating element 50, on which the actuating lever 5 can be manually actuated.
  • the actuating lever 5 extends from the manual actuating element 50 into an area in which the actuating lever 50 forks into a side cheek 51 arranged on the left and a side cheek 51 on the right.
  • the side cheeks 51 can extend laterally, for example, beyond the holding frame 6.
  • Respective spring actuating bodies are attached to the inner sides of the side cheeks 51 facing one another, on each of which a first and a second bearing disk 52 is arranged.
  • the actuating lever 5 is pivotable, i.e. rotatable, in the conductor connection terminal 1 via the bearing disks 52 and can be supported in particular on the surface 30 of the busbar 3. In this case, the operating lever 5 slides with the bearing discs 52 on the busbar 3 during a pivoting movement.
  • the spring actuating bodies each have a V-shaped notch through which a respective actuating edge 53 is formed.
  • the actuating edge 53 acts on the clamping leg 43. If the actuating lever 5 is released from the Figure 1 shown closed position into an open position by pivoting it counterclockwise through an angle of approximately 90 degrees, the clamping leg 43 is deflected upwards in the direction of the contact leg 41 by the actuating edge 53, whereby the free end 44 or the clamping edge is moved away from the busbar 3.
  • the Figure 2 shows the conductor connection terminal 1 in a plan view of the conductor insertion side 11.
  • the busbar 3 extends completely through the housing 2 in the transverse direction Q, i.e. the receiving space 25 also extends completely through the conductor connection terminal 1 in the transverse direction Q.
  • the Figure 3 shows a sectional view of the conductor connection terminal 1 according to the section line AA of the Figure 1 This also clarifies the elements already explained. This is particularly evident in the Figure 3 that the holding frame 6 has a recess 61 which is delimited by webs 60, 63, 64 and downwards, on the side of the recess 61 opposite the web 60, by the adjoining region of the tension element 62.
  • the Figure 4 shows an alternative embodiment of the locking fastening of the busbar 3 by means of the positioning element 28.
  • the positioning element 28 is guided via a U-shaped arm from the first housing component 20 to a side edge of the busbar 3.
  • the insertion opening 24 is arranged on the same side of the housing 2 as the conductor insertion opening 23, namely on the conductor insertion side 11, the Figures 5 to 7 illustrated embodiment of the conductor connection terminal 1, a variant is explained in which the insertion opening 24 is arranged on the side of the housing 2 facing away from the actuating side 10.
  • the section of the busbar 3 is inserted into the housing 2 from below, so to speak.
  • the busbar 3 is introduced into the receiving space 25 in such a way that it is first pushed between the free end 44 of the clamping leg 43 and the tension element 62 and is then locked in place behind the positioning element 28 by means of a tilting movement.

Aus der US 9,525,219 B2 ist eine Leiteranschlussklemme mit Federkraftklemmanschluss bekannt, die eine interne Stromschiene hat. Aus der DE 201 20 811 U1 ist eine Sammelschienen-Anschlussklemme bekannt. Aus der US 2015/0372402 A1 ist eine Leiteranschlussklemme mit Federkraftklemmanschlüssen und einer durchgehenden internen Stromschiene bekannt. Aus der JP 2004 165045 A ist eine weitere Sammelschienen-Anschlussklemme bekannt.Such a conductor connection terminal is from the EN 10 2013 107 292 A1 known. From the US9,525,219 B2 A conductor terminal with spring clamp connection is known, which has an internal busbar. From the DE 201 20 811 U1 A busbar terminal is known. From the US 2015/0372402 A1 A conductor terminal with spring clamp connections and a continuous internal busbar is known. JP 2004 165045 A Another busbar connection terminal is known.

Der Erfindung liegt die Aufgabe zugrunde, eine solche Leiteranschlussklemme weiter zu optimieren.The invention is based on the object of further optimizing such a conductor connection terminal.

Diese Aufgabe wird durch eine Leiteranschlussklemme gemäß Anspruch 1 gelöst. Die Leiteranschlussklemme dient zum Anschließen eines elektrischen Leiters mittels Federkraftklemmung, wobei die Leiteranschlussklemme zum Aufstecken auf eine Sammelschiene eingerichtet ist, wobei die Leiteranschlussklemme wenigstens einen Federkraftklemmanschluss mit einer Klemmfeder zum Anklemmen des elektrischen Leiters, ein den Federkraftklemmanschluss zumindest teilweise umgebendes Gehäuse mit einer Leitereinführöffnung und einen schwenkbar gelagerten Betätigungshebel aufweist, der zur Betätigung wenigstens eines Teils der Klemmfeder eingerichtet ist, wobei im Gehäuse ein Aufnahmeraum zur Aufnahme wenigstens eines Abschnitts der Sammelschiene vorhanden ist, auf die die Leiteranschlussklemme aufsteckbar ist. Auf diese Weise kann die erfindungsgemäße Leiteranschlussklemme mit einem einfachen und kompakten Aufbau realisiert werden. Es kann eine einfache und sichere Hebelbetätigung mit sicherer Klemmung realisiert werden. Die Leiteranschlussklemme erlaubt ein einfaches Aufrasten oder sonstiges Aufsetzen auf die Sammelschiene.This object is achieved by a conductor connection terminal according to claim 1. The conductor connection terminal serves to connect an electrical conductor by means of spring clamping, wherein the conductor connection terminal is designed to be plugged onto a busbar, wherein the conductor connection terminal has at least one spring clamp connection with a clamping spring for clamping the electrical conductor, a housing at least partially surrounding the spring clamp connection with a conductor insertion opening and a pivotably mounted actuating lever which is designed to actuate at least part of the clamping spring, wherein a receiving space is provided in the housing for receiving at least a section of the busbar onto which the conductor connection terminal can be plugged. In this way, the conductor connection terminal according to the invention can be realized with a simple and compact structure. A simple and safe lever operation with secure clamping can be achieved. The conductor connection terminal allows easy snapping or other attachment to the busbar.

Durch die Leitereinführöffnung kann der anzuklemmende elektrische Leiter in einer Leitereinführrichtung in das Gehäuse eingeführt und zu einer Klemmstelle des Federkraftklemmanschlusses geführt werden. An die Leitereinführöffnung kann sich innerhalb des Gehäuses ein Leitereinführkanal anschließen. Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind der Leitereinführkanal und der Aufnahmeraum derart zueinander angeordnet, dass sie ineinander übergehen, so dass eine im Aufnahmeraum aufgenommene Sammelschiene in den Leitereinführkanal zumindest teilweise hineinragt.The electrical conductor to be connected can be introduced into the housing in a conductor insertion direction through the conductor insertion opening and guided to a terminal point of the spring-loaded terminal connection. A conductor insertion channel can be connected to the conductor insertion opening within the housing. According to an advantageous embodiment of the invention, the conductor insertion channel and the receiving space are arranged in such a way that they merge into one another, so that a busbar received in the receiving space at least partially protrudes into the conductor insertion channel.

Gemäß der Erfindung ist vorgesehen, dass wenigstens ein Bereich des Betätigungshebels an den Aufnahmeraum der Sammelschiene angrenzt oder in den Aufnahmeraum der Sammelschiene hineinragt. Auf diese Weise kann der Betätigungshebel die Oberfläche der Sammelschiene zumindest zum Teil als Abstütz- und Gleitfläche während der Verschwenkbewegung nutzen. Daher kann der Aufbau der Leiteranschlussklemme vereinfacht werden, da insbesondere die für die Verschwenkbewegung erforderliche Lagerung des Betätigungshebels weniger Aufwand hinsichtlich der konstruktiven Gestaltung der Leiteranschlussklemme erfordert.According to the invention, it is provided that at least one area of the actuating lever adjoins the receiving space of the busbar or protrudes into the receiving space of the busbar. In this way, the actuating lever can use the surface of the busbar at least in part as a support and sliding surface during the pivoting movement. The structure of the conductor connection terminal can therefore be simplified, since in particular the bearing of the actuating lever required for the pivoting movement requires less effort with regard to the structural design of the conductor connection terminal.

Gemäß der Erfindung ist vorgesehen, dass wenigstens ein Teil des Betätigungshebels zumindest während einer Verschwenkbewegung des Betätigungshebels auf der in dem Aufnahmeraum aufgenommenen Sammelschiene auflagerbar ist. Der Betätigungshebel kann somit während der Verschwenkbewegung zumindest zum Teil auf der Oberfläche der Sammelschiene entlang geleiten.According to the invention, it is provided that at least a part of the actuating lever can be supported on the busbar accommodated in the receiving space, at least during a pivoting movement of the actuating lever. The actuating lever can thus slide at least partially along the surface of the busbar during the pivoting movement.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Leiteranschlussklemme Positionierelemente zur Positionierung der Sammelschiene relativ zum Aufnahmeraum in einer Einbaulage aufweist, in der die Sammelschiene schräg gegenüber der Leitereinführungsrichtung angeordnet ist. Auf diese Weise wird durch die Positionierelemente eine bestimmte Lage des im Aufnahmeraum vorhandenen Abschnitts der Sammelschiene gegenüber der Leitereinführrichtung und damit auch bezüglich des angeklemmten elektrischen Leiters definiert. Durch die Positionierelemente kann somit die Sammelschiene in der Einbaulage festgelegt werden. Der elektrische Leiter ist durch diese Einbaulage der Sammelschiene insbesondere nicht parallel zur Sammelschiene angeordnet, sondern in einem gewissen Winkel dazu, beispielsweise in einem spitzen Winkel. Der Winkel zwischen der Leitereinführrichtung und der zum elektrischen Leiter gewandten Oberfläche der Stromschiene kann zum Beispiel im Bereich von 5 bis 45 Grad liegen. Dies erlaubt eine besonders zuverlässige Klemmung des elektrischen Leiters, wobei der in dem Aufnahmeraum befindliche Abschnitt der Sammelschiene zum Anklemmen des elektrischen Leiters genutzt werden kann. Durch die schräge Führung des elektrischen Leiters zur Oberfläche der Sammelschiene wird eine Flächenauflage des elektrischen Leiters an der Sammelschiene vermieden.According to an advantageous embodiment of the invention, the conductor connection terminal has positioning elements for positioning the busbar relative to the receiving space in an installation position in which the busbar is arranged obliquely relative to the conductor insertion direction. In this way, the positioning elements determine a specific position of the section of the busbar present in the receiving space relative to the conductor insertion direction and and thus also defined with regard to the clamped-on electrical conductor. The positioning elements can thus be used to fix the busbar in its installation position. As a result of this installation position of the busbar, the electrical conductor is not arranged parallel to the busbar, but at a certain angle to it, for example at an acute angle. The angle between the conductor insertion direction and the surface of the busbar facing the electrical conductor can, for example, be in the range of 5 to 45 degrees. This allows the electrical conductor to be clamped particularly reliably, whereby the section of the busbar located in the receiving space can be used to clamp the electrical conductor. By guiding the electrical conductor at an angle to the surface of the busbar, the electrical conductor does not come into contact with the busbar.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Positionierelemente eines oder mehrere Rastelemente aufweisen, durch die die Leiteranschlussklemme rastend mit der Sammelschiene verbindbar ist. Dies ermöglicht ein einfaches Aufrasten der Leiteranschlussklemme auf die Sammelschiene. Die Leiteranschlussklemme kann insbesondere derart ausgebildet sein, dass keine Positionierelemente gesondert manuell betätigt werden müssen, um die Leiteranschlussklemme mit der Sammelschiene zu verbinden. Das Gehäuse der Leiteranschlussklemme kann als ein aus einem oder mehreren Bauteilen bestehendes Gehäuse ausgebildet sein, wobei das Gehäuse mit seinen einen oder mehreren Bauteilen insgesamt starr ausgebildet sein kann. Ein Gelenk zum Öffnen oder Schließen des Gehäuses ist nicht erforderlich.According to an advantageous embodiment of the invention, the positioning elements have one or more locking elements, by means of which the conductor connection terminal can be connected to the busbar in a locking manner. This enables the conductor connection terminal to be easily locked onto the busbar. The conductor connection terminal can in particular be designed in such a way that no positioning elements have to be separately operated manually in order to connect the conductor connection terminal to the busbar. The housing of the conductor connection terminal can be designed as a housing consisting of one or more components, whereby the housing with its one or more components can be designed to be rigid overall. A joint for opening or closing the housing is not required.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass sich der Aufnahmeraum in einer Querrichtung, die orthogonal zur Leitereinführungsrichtung verläuft, vollständig durch die Leiteranschlussklemme hindurcherstreckt. Das Gehäuse der Leiteranschlussklemme, das zum Beispiel als Isolierstoffgehäuse ausgebildet sein kann, ist somit im Bereich des Aufnahmeraums seitlich offen. Dementsprechend kann die Leiteranschlussklemme auch auf eine Sammelschiene aufgesteckt werden, die eine relativ große Längserstreckung aufweist.According to an advantageous embodiment of the invention, it is provided that the receiving space extends completely through the conductor connection terminal in a transverse direction that runs orthogonal to the conductor insertion direction. The housing of the conductor connection terminal, which can be designed as an insulating housing, for example, is thus open at the side in the area of the receiving space. Accordingly, the conductor connection terminal can also be plugged onto a busbar that has a relatively large longitudinal extension.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Klemmfeder einen Anlageschenkel, einen sich an den Anlageschenkel anschließenden Federbogen und einen sich an den Federbogen anschließenden Klemmschenkel zum Festklemmen des elektrischen Leiters aufweist. Dabei kann die Klemmfeder mittels des Anlageschenkels an einem Teil der Leiteranschlussklemme gegenüber der Klemmkraft des Klemmschenkels abgestützt sein. Durch die Klemmkraft des Klemmschenkels kann der elektrische Leiter festgeklemmt werden. Hierzu kann die Leiteranschlussklemme beispielsweise eine Stromschiene aufweisen, gegen die der elektrische Leiter mittels des Klemmschenkels gepresst wird, oder ein Bereich der Oberfläche der Sammelschiene kann zum Anklemmen des elektrischen Leiters genutzt werden. Der Klemmschenkel kann unmittelbar auf die Sammelschiene einwirken, oder über eines oder mehrere weitere Elemente, beispielsweise eine Stromschiene und/oder den angeklemmten elektrischen Leiter.According to an advantageous embodiment of the invention, the clamping spring has a contact leg, a spring arch adjoining the contact leg, and a clamping leg adjoining the spring arch for clamping the electrical conductor. The clamping spring can be supported by means of the contact leg on a part of the conductor connection terminal against the clamping force of the clamping leg. The electrical conductor can be clamped by the clamping force of the clamping leg. For this purpose, the conductor connection terminal can have, for example, a busbar against which the electrical conductor is pressed by means of the clamping leg, or an area of the surface of the busbar can be used to clamp the electrical conductor. The clamping leg can act directly on the busbar, or via one or more other elements, for example a busbar and/or the clamped electrical conductor.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Leiteranschlussklemme einen Halterahmen aufweist, an dem der Anlageschenkel gehalten ist, z.B. indem der Anlageschenkel dort aufgenommen, eingehängt oder fixiert ist. Der Halterahmen kann zum Beispiel als Metallteil ausgebildet sein. Der Halterahmen kann eine umfangsseitig durch Stege umrandete Öffnung aufweisen, durch die zumindest ein freies Ende des einzuklemmenden elektrischen Leiters hindurchgeführt werden kann. Der Anlageschenkel kann zum Beispiel am Innenumfang der Öffnung an dem Halterahmen eingehängt sein.According to an advantageous embodiment of the invention, the conductor connection terminal has a holding frame on which the contact leg is held, e.g. by the contact leg being received, suspended or fixed there. The holding frame can be designed as a metal part, for example. The holding frame can have an opening surrounded by webs on the circumference, through which at least one free end of the electrical conductor to be clamped can be passed. The contact leg can be suspended on the holding frame, for example, on the inner circumference of the opening.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Halterahmen ein Zugelement aufweist oder mit einem Zugelement gekoppelt ist. An dem Zugelement kann die Sammelschiene in dem Aufnahmeraum gegenüber einer auf die Sammelschiene einwirkenden Klemmkraft des Klemmschenkels abstützbar sein. Durch das Zugelement, das z.B. als Zugstange ausgebildet sein kann, kann eine reine Zugkraft von der Sammelschiene zu der Befestigungsstelle des Anlageschenkels übertragen werden. Der Federkraftklemmanschluss kann dabei über das Zugelement selbsttragend an der Sammelschiene gehalten werden. Bei einem solchen selbsttragenden System werden keine oder nur vernachlässigbare Kräfte der Klemmfeder auf das Gehäuse übertragen. Hierdurch kann insbesondere ein geschlossener Kraftfluss zwischen dem Zugelement, dem Halterahmen und der Sammelschiene geschaffen werden.According to an advantageous embodiment of the invention, the holding frame has a tension element or is coupled to a tension element. The busbar in the receiving space can be supported on the tension element against a clamping force of the clamping leg acting on the busbar. The tension element, which can be designed as a pull rod, for example, can transfer a pure tensile force from the busbar to the fastening point of the contact leg. The spring-loaded clamp connection can be held self-supportingly on the busbar via the tension element. In such a self-supporting system, no or only negligible forces of the clamping spring are transferred to the housing. This makes it possible in particular to create a closed Force flow must be created between the tension element, the holding frame and the busbar.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das freie Ende des Klemmschenkels derart positioniert ist, dass zwischen einem freien Ende und einer dem Klemmschenkel zugewandten Oberfläche einer im Aufnahmeraum befindlichen Sammelschiene eine Klemmstelle zum Anklemmen des elektrischen Leiters gebildet ist. Auf diese Weise kann die Sammelschiene als Klemmfläche für den elektrischen Leiter genutzt werden. Die Leiteranschlussklemme kann dementsprechend ohne eigene Stromschiene ausgebildet sein, das heißt stromschienenlos. Hierdurch kann der Aufbau der Leiteranschlussklemme weiter vereinfacht werden.According to an advantageous embodiment of the invention, the free end of the clamping leg is positioned in such a way that a clamping point for clamping the electrical conductor is formed between a free end and a surface of a busbar located in the receiving space facing the clamping leg. In this way, the busbar can be used as a clamping surface for the electrical conductor. The conductor connection terminal can therefore be designed without its own busbar, i.e. without a busbar. This can further simplify the structure of the conductor connection terminal.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass ein an der Klemmstelle angeklemmter elektrischer Leiter zwischen dem freien Ende des Klemmschenkels und einer Eckkante der Sammelschiene anklemmbar ist. Dies erlaubt eine besonders zuverlässige Klemmung des elektrischen Leiters an der Klemmstelle. Hierzu kann der Aufnahmeraum Positionierelemente aufweisen, welche die im Aufnahmeraum aufgenommene Sammelschiene derart positionieren, dass eine Eckkante zum freien Ende des Klemmschenkels so positioniert ist, dass ein angeklemmter elektrischer Leiter zwischen dem freien Ende und der Eckkante anklemmbar ist.According to an advantageous embodiment of the invention, it is provided that an electrical conductor clamped to the clamping point can be clamped between the free end of the clamping leg and a corner edge of the busbar. This allows a particularly reliable clamping of the electrical conductor at the clamping point. For this purpose, the receiving space can have positioning elements which position the busbar received in the receiving space in such a way that a corner edge is positioned towards the free end of the clamping leg in such a way that a clamped electrical conductor can be clamped between the free end and the corner edge.

Der Klemmschenkel kann an seinem freien Ende eine Klemmkante aufweisen. Hierdurch wird die Zuverlässigkeit der Klemmung des elektrischen Leiters weiter verbessert.The clamping leg can have a clamping edge at its free end. This further improves the reliability of the clamping of the electrical conductor.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Gehäuse eine Einsetzöffnung aufweist, durch die ein Abschnitt der Sammelschiene in den Aufnahmeraum der Leiteranschlussklemme einsetzbar ist. Dabei kann die Einsetzöffnung an der gleichen Gehäuseseite des Gehäuses wie die Leitereinführungsöffnung oder an einer von einer Betätigungsseite der Leiteranschlussklemme abgewandten Gehäuseseite des Gehäuses angeordnet sein. Die Betätigungsseite der Leiteranschlussklemme ist eine Seite, an der ein manuelles Betätigungselement des Betätigungshebels für die manuelle Betätigung zugänglich ist. Dies erlaubt ein besonders einfaches Einsetzen des Abschnitts der Sammelschiene in den Aufnahmeraum beziehungsweise ein einfaches Anstecken der Leiteranschlussklemme an die Sammelschiene.According to an advantageous embodiment of the invention, the housing has an insertion opening through which a section of the busbar can be inserted into the receiving space of the conductor connection terminal. The insertion opening can be arranged on the same side of the housing as the conductor insertion opening or on a side of the housing facing away from an actuating side of the conductor connection terminal. The actuating side of the conductor connection terminal is a side on which a manual actuating element of the operating lever is accessible for manual operation. This allows a particularly easy insertion of the section of the busbar into the receiving space or a simple plugging of the conductor connection terminal onto the busbar.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Betätigungshebel in Leitereinführrichtung gesehen U-förmig ausgebildet ist, mit jeweils einer ersten und einer zweiten Lagerungsscheibe, die über einen Verbindungsbereich des Betätigungshebels miteinander verbunden sind, wobei zwischen der ersten und der zweiten Lagerungsscheibe ein Zwischenraum zur Durchführung des anzuklemmenden elektrischen Leiters vorhanden ist. Durch eine solche Konstruktion kann der Betätigungshebel bei kompakter Bauweise große Betätigungskräfte auf die Klemmfeder übertragen. Zudem kann die Leiteranschlussklemme insgesamt sehr kompakt gestaltet werden, da der Zwischenraum zwischen den Lagerungsscheiben für das Hindurchführen des elektrischen Leiters genutzt werden kann.According to an advantageous embodiment of the invention, the actuating lever is U-shaped when viewed in the conductor insertion direction, with a first and a second bearing disc, which are connected to one another via a connecting region of the actuating lever, with a gap between the first and the second bearing disc for the electrical conductor to be clamped through. With such a construction, the actuating lever can transmit large actuating forces to the clamping spring with a compact design. In addition, the conductor connection terminal can be designed to be very compact overall, since the gap between the bearing discs can be used to guide the electrical conductor through.

Die erste und die zweite Lagerungsscheibe können beispielsweise auf der Oberfläche der Sammelschiene aufgelagert sein und darauf abgleiten, wenn eine Verschwenkbewegung des Betätigungshebels durchgeführt wird.The first and second bearing discs can, for example, be supported on the surface of the busbar and slide thereon when a pivoting movement of the operating lever is carried out.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der U-förmig ausgebildete Teil des Betätigungshebels eine offene Seite hat, welche so positioniert ist, dass sie durch die Oberfläche der im Aufnahmeraum aufgenommenen Sammelschiene abdeckbar ist. Durch die im Aufnahmeraum aufgenommene Sammelschiene kann somit die offene Seite der U-Form geschlossen werden.According to an advantageous embodiment of the invention, the U-shaped part of the actuating lever has an open side which is positioned such that it can be covered by the surface of the busbar accommodated in the receiving space. The open side of the U-shape can thus be closed by the busbar accommodated in the receiving space.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die erste und die zweite Lagerungsscheibe in jeder Betätigungsstellung des Betätigungshebels eine Führung für den durch den Zwischenraum geführten elektrischen Leiter bilden. Dementsprechend wird bereits durch den Betätigungshebel eine Führung für den elektrischen Leiter bereitgestellt. Die Führung kann in jedem Betriebszustand der Leiteranschlussklemme, insbesondere in jeder Verschwenkstellung des Betätigungshebels, durch die erste und die zweite Lagerungsscheibe gewährleistet werden. Die Leiteranschlussklemme kann weitere Leiterführungselemente aufweisen, wie nachfolgend noch erläutert wird.According to an advantageous embodiment of the invention, the first and second bearing discs form a guide for the electrical conductor guided through the gap in each actuation position of the actuation lever. Accordingly, a guide for the electrical conductor is already provided by the actuation lever. The guidance can be ensured in every operating state of the conductor connection terminal, in particular in every pivot position of the actuation lever, by the first and second bearing discs. The Conductor connection terminal can have additional conductor guiding elements, as explained below.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Leiteranschlussklemme für einen jeweiligen Federkraftklemmanschluss nur eine einzige Feder aufweist, nämlich die Klemmfeder des Federkraftklemmanschlusses. Hierdurch ist die Leiteranschlussklemme einfach und mit nur wenigen Bauteilen aufgebaut. Dies vereinfacht sowohl die Herstellung als auch die Montage der Leiteranschlussklemme.According to an advantageous embodiment of the invention, the conductor connection terminal has only one spring for each spring clamp connection, namely the clamping spring of the spring clamp connection. As a result, the conductor connection terminal is simple and has only a few components. This simplifies both the manufacture and the assembly of the conductor connection terminal.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Klemmfeder im Wesentlichen V-förmig ausgebildet ist. Auf diese Weise kann der Federkraftklemmanschluss als Direkteckanschluss ausgebildet sein. Bei einem Direktsteckanschluss kann ein elektrischer Leiter, wenn er ausreichend steif ist (zum Beispiel ein eindrähtiger Leiter), direkt ohne Betätigung des Betätigungshebels in die Klemmstelle eingeführt werden und mittels des Klemmschenkels festgeklemmt werden. Lediglich zum Entfernen des angeklemmten elektrischen Leiters von der Klemmstelle ist eine Betätigung des Betätigungshebels erforderlich.According to an advantageous embodiment of the invention, the clamping spring is essentially V-shaped. In this way, the spring-loaded clamp connection can be designed as a direct corner connection. With a direct plug connection, an electrical conductor, if it is sufficiently rigid (for example a single-wire conductor), can be inserted directly into the clamping point without operating the operating lever and can be clamped in place using the clamping leg. The operating lever only needs to be operated to remove the clamped electrical conductor from the clamping point.

Der Betätigungshebel kann beispielsweise eine Offen-Stellung und eine Geschlossen-Stellung aufweisen. In der Offen-Stellung ist die Klemmstelle geöffnet, das heißt, der Klemmschenkel ist soweit von dem zur Klemmung genutzten Gegenstück (zum Beispiel Stromschiene oder Sammelschiene) entfernt, dass ein elektrischer Leiter ohne Kraftaufwand in die Klemmstelle eingeführt werden oder von dort entfernt werden kann. In der Geschlossen-Stellung ist der Klemmschenkel hinsichtlich des Festklemmens des elektrischen Leiters an der Klemmstelle wirksam.The operating lever can, for example, have an open position and a closed position. In the open position, the clamping point is open, i.e. the clamping leg is far enough away from the counterpart used for clamping (e.g. busbar or busbar) that an electrical conductor can be inserted into or removed from the clamping point without the need for force. In the closed position, the clamping leg is effective in clamping the electrical conductor to the clamping point.

Der Betätigungshebel kann, insbesondere im Bereich seiner Lagerung, beweglich und/oder schwimmend in der Leiteranschlussklemme gelagert sein. Insbesondre kann der Betätigungshebel im Bereich seiner Lagerung eine geringfügig andere Position in der Leiteranschlussklemme einnehmen, wenn keine Sammelschiene im Aufnahmeraum angeordnet ist, im Vergleich zum Zustand einer im Aufnahmeraum angeordneten Sammelschiene. Mit anderen Worten, durch das Einsetzen der Sammelschiene in den Aufnahmeraum kann der Betätigungshebel im Bereich seiner Lagerung um ein gewisses (in der Regel relativ geringes) Maß durch die Sammelschiene verdrängt werden.The operating lever can be mounted in the conductor terminal in a movable and/or floating manner, particularly in the area of its bearing. In particular, the operating lever can assume a slightly different position in the conductor terminal in the area of its bearing if no busbar is arranged in the receiving space, compared to the state of a busbar arranged in the receiving space. In other words, by inserting the busbar In the receiving space, the operating lever can be displaced by the busbar in the area of its bearing to a certain (usually relatively small) extent.

Im Sinne der vorliegenden Erfindung ist unter dem unbestimmten Begriff "ein" kein Zahlwort zu verstehen. Wenn also z.B. von einem Bauteil die Rede ist, so ist dies im Sinne von "mindestens einem Bauteil" zu interpretieren. Soweit Winkelangaben in Grad gemacht werden, beziehen sich diese auf ein Kreismaß von 360 Grad (360°).For the purposes of the present invention, the indefinite term "a" is not to be understood as a number. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component". If angles are given in degrees, these refer to a circular dimension of 360 degrees (360°).

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Verwendung von Zeichnungen näher erläutert.The invention is explained in more detail below using embodiments and drawings.

Die in Figur 1 dargestellte Leiteranschlussklemme 1 weist ein Gehäuse 2, eine Klemmfeder 4, einen Betätigungshebel 5 und einen Halterahmen 6 auf. Das Gehäuse 2 kann beispielsweise kann beispielsweise zweiteilig mit einem ersten Gehäusebauteil 20 und einem zweiten Gehäusebauteil 21 ausgebildet sein. Das erste und das zweite Gehäusebauteil 20, 21 können über Positionierelemente aneinander befestigt werden, beispielsweise indem sie aneinander verrastet werden. In dem vom Gehäuse 2 umgebenen Bereich ist die Klemmfeder 4 und der Halterahmen 6 angeordnet. Die Figur 1 zeigt zusätzlich eine Sammelschiene 3, an der die Leiteranschlussklemme 1 befestigt ist.In the Figure 1 The conductor connection terminal 1 shown has a housing 2, a clamping spring 4, an actuating lever 5 and a holding frame 6. The housing 2 can, for example, be designed in two parts with a first housing component 20 and a second housing component 21. The first and second housing components 20, 21 can be attached to one another via positioning elements, for example by locking them together. The clamping spring 4 and the holding frame 6 are arranged in the area surrounded by the housing 2. The Figure 1 additionally shows a busbar 3 to which the conductor connection terminal 1 is attached.

Das Gehäuse 2 weist eine Leiteraufnahmekammer 22, eine Leitereinführungsöffnung 23, eine Einsetzöffnung 24, einen Aufnahmeraum 25 zur Aufnahme eines Abschnitts der Sammelschiene 3 sowie Positionierelemente 26, 27, 28 auf, die zur Positionierung der Sammelschiene 3 relativ zum Aufnahmeraum 25 in einer definierten Einbaulage dienen. Die Leiteraufnahmekammer 22 kann zum Beispiel durch einen Teil des zweiten Gehäusebauteils 21 gebildet sein, die übrigen erwähnten Elemente des Gehäuses 2 können am ersten Gehäusebauteil 20 ausgebildet sein. Die Leitereinführungsöffnung 23 befindet sich an einer Leitereinführseite 11 der Leiteranschlussklemme 1. An die Leitereinführungsöffnung 23 schließt sich im Inneren des Gehäuses 2 ein Leitereinführungskanal 98 an, der beispielsweise zumindest teilweise durch Wände des Gehäuses 2 umgeben sein kann.The housing 2 has a conductor receiving chamber 22, a conductor insertion opening 23, an insertion opening 24, a receiving space 25 for receiving a section of the busbar 3 and positioning elements 26, 27, 28 which serve to position the busbar 3 relative to the receiving space 25 in a defined installation position. The conductor receiving chamber 22 can be formed, for example, by a part of the second housing component 21, the other mentioned elements of the housing 2 can be formed on the first housing component 20. The conductor insertion opening 23 is located on a conductor insertion side 11 of the conductor connection terminal 1. The conductor insertion opening 23 is followed in the interior of the housing 2 by a conductor insertion channel 98 which can, for example, be at least partially surrounded by walls of the housing 2.

Ein elektrischer Leiter, der an der Leiteranschlussklemme 1 angeschlossen werden soll, kann in einer Leitereinführrichtung L durch die Leitereinführöffnung 23 zu einer nachfolgend noch erläuterten Klemmstelle geführt werden. Die Einsetzöffnung 24 dient zum Einsetzen eines Abschnitts der Sammelschiene 3 in den Aufnahmeraum 25. Ist dieser Abschnitt der Sammelschiene 3 vollständig eingesetzt, ergibt sich der in Figur 1 dargestellte Zustand, in dem der Aufnahmeraum 25 weitestgehend durch diesen Abschnitt der Sammelschiene 3 ausgefüllt ist. Wie man erkennt, ragt die Sammelschiene 3 zumindest ein Stück weit in den Leitereinführungskanal 98 hinein.An electrical conductor that is to be connected to the conductor connection terminal 1 can be guided in a conductor insertion direction L through the conductor insertion opening 23 to a terminal point explained below. The insertion opening 24 is used to insert a section of the busbar 3 into the receiving space 25. If this section of the busbar 3 is completely inserted, the in Figure 1 shown state, in which the receiving space 25 is largely filled by this section of the busbar 3. As can be seen, the busbar 3 protrudes at least a little way into the conductor entry channel 98.

Die Positionierelemente 26, 27 können beispielsweise als einander gegenüberliegende Gleitkanten des Gehäuses 2 ausgebildet sein, an denen die Sammelschiene während ihres Einsetzens durch die Einsetzöffnung 24 in den Aufnahmeraum 25 geführt ist und letztendlich in der Einbaulage gehalten ist. Das Positionierelement 28 kann als Rastelement ausgebildet sein, das an einer federnden Rastzunge des Gehäuses 2 angeordnet ist. Diese Rastzunge gibt beim Einsetzen der Sammelschiene 3 etwas nach und schnappt dann bei Erreichen der Einbaulage der Sammelschiene 3 in dem Aufnahmeraum 25 wieder zurück, wodurch die Sammelschiene 3 durch Verrastung in dem Aufnahmeraum 25 fixiert ist. Auf der dem Positionierelement 28 abgewandten Seite kann die Position der Sammelschiene 3 beispielsweise durch den Halterahmen 6 fixiert sein.The positioning elements 26, 27 can be designed, for example, as mutually opposite sliding edges of the housing 2, on which the busbar is guided during its insertion through the insertion opening 24 into the receiving space 25 and is ultimately held in the installation position. The positioning element 28 can be designed as a locking element that is arranged on a spring-loaded locking tongue of the housing 2. This locking tongue gives way slightly when the busbar 3 is inserted and then snaps back again when the installation position of the busbar 3 in the receiving space 25 is reached, whereby the busbar 3 is fixed in the receiving space 25 by locking. On the side facing away from the positioning element 28, the position of the busbar 3 can be fixed, for example, by the holding frame 6.

Die Klemmfeder 4 weist einen Anlageschenkel 41, einen sich an den Anlageschenkel 41 anschließenden Federbogen 42 und einen sich an den Federbogen 42 anschließenden Klemmschenkel 43 auf. Der Anlageschenkel ist über sein freies Ende 40 an dem Halterahmen 6 fixiert und dort abgestützt, beispielsweise indem das freie Ende 40 dort hinter einem Steg 60 des Halterahmens 6 eingehängt ist. Der Steg 60 kann auf diese Weise ein erstes Lager 60 zur Aufnahme des Anlageschenkels 41 bilden. Der Klemmschenkel 43 endet an einem freien Ende 44, an dem eine Klemmkante vorhanden sein kann. Mittels des freien Endes 44 beziehungsweise der Klemmkante kann ein elektrischer Leiter an einer Oberfläche 30 der Sammelschiene 3 angeklemmt werden. Die Klemmstelle des aus diese Weise realisierten Federkraftklemmanschlusses wird somit zwischen dem freien Ende 44 beziehungsweise der Klemmkante des Klemmschenkels 43 und der Oberfläche 30 der Sammelschiene 3 gebildet. Die Klemmstelle kann insbesondere unter Zuhilfenahme der Eckkante 31 der Sammelschiene 3 gebildet sein.The clamping spring 4 has a contact leg 41, a spring arch 42 adjoining the contact leg 41 and a clamping leg 43 adjoining the spring arch 42. The contact leg is fixed to the holding frame 6 via its free end 40 and supported there, for example by the free end 40 being suspended there behind a web 60 of the holding frame 6. The web 60 can in this way form a first bearing 60 for receiving the contact leg 41. The clamping leg 43 ends at a free end 44, on which a clamping edge can be present. By means of the free end 44 or the clamping edge, an electrical conductor can be clamped to a surface 30 of the busbar 3. The clamping point of the spring force clamp connection realized in this way is thus formed between the free end 44 or the clamping edge of the clamping leg 43 and the surface 30 of the busbar 3. The clamping point can be formed in particular with the aid of the corner edge 31 of the busbar 3.

Der Halterahmen 6 weist eine Aussparung 61 auf. Ein anzuklemmender elektrischer Leiter, der durch die Leitereinführungsöffnung 23 eingeführt wird, wird zunächst durch den sich an die Leitereinführungsöffnung 23 anschließenden Leitereinführungskanal 98 geführt. Im Bereich des Betätigungshebels 5 erfolgt die Führung des elektrischen Leiters durch jeweils seitlich angeordnete Lagerungsscheiben 52. An der Leiterführung sind außerdem der der Klemmschenkel 43 und die Oberfläche 30 der Sammelschiene 3 beteiligt. Der elektrische Leiter kann durch die Aussparung 61 hindurch bis in den Leiteraufnahmeraum 22 eingeführt werden, durch den auch ein Endanschlag zur Begrenzung der Tiefe des Einsteckens des elektrischen Leiters gebildet ist.The holding frame 6 has a recess 61. An electrical conductor to be connected, which is inserted through the conductor insertion opening 23, is first through the conductor insertion channel 98 adjoining the conductor insertion opening 23. In the area of the actuating lever 5, the electrical conductor is guided by bearing disks 52 arranged on the sides. The clamping leg 43 and the surface 30 of the busbar 3 also play a role in guiding the conductor. The electrical conductor can be inserted through the recess 61 into the conductor receiving space 22, which also forms an end stop to limit the depth of insertion of the electrical conductor.

Der Halterahmen 6 wird unterhalb der Aussparung 61 durch ein Zugelement 62 fortgesetzt, hinter dem die Sammelschiene 3 eingehängt ist. Das Zugelement 62 kann zum Beispiel mit einem abgebogenen freien Ende enden, das ein zweites Lager 99 bildet, auf dem die Sammelschiene 3 aufliegt. Die Klemmfeder 4 überträgt durch den Klemmschenkel 43 eine Klemmkraft direkt oder indirekt auf die Sammelschiene 3. Gegenüber dieser Klemmkraft wird die Sammelschiene 3 durch das Zugelement 62 abgestützt, das wiederum über den Halterahmen 6 mit dem Anlageschenkel 41 verbunden ist. Auf diese Weise wird ein selbsttragender Kontakteinsatz der Leiteranschlussklemme 1 realisiert.The holding frame 6 is continued below the recess 61 by a tension element 62, behind which the busbar 3 is suspended. The tension element 62 can, for example, end with a bent free end that forms a second bearing 99 on which the busbar 3 rests. The clamping spring 4 transmits a clamping force directly or indirectly to the busbar 3 through the clamping leg 43. The busbar 3 is supported against this clamping force by the tension element 62, which in turn is connected to the contact leg 41 via the holding frame 6. In this way, a self-supporting contact insert of the conductor connection terminal 1 is realized.

Der Betätigungshebel 5 ist zwecks manueller Betätigung an einer Betätigungsseite 10 der Leiteranschlussklemme 1 zugänglich. Der Betätigungshebel 5 weist ein manuelles Betätigungselement 50 auf, an dem der Betätigungshebel 5 manuell zu betätigen ist. Der Betätigungshebel 5 geht vom manuellen Betätigungselement 50 über in einen Bereich, in dem der Betätigungshebel 50 sich aufgabelt in jeweils eine links und eine rechts angeordnete Seitenwange 51. Die Seitenwangen 51 können sich seitlich beispielsweise noch über den Halterahmen 6 hinaus erstrecken. An denen einander zugewandten Innenseiten der Seitenwangen 51 sind jeweilige Federbetätigungskörper angebracht, an denen jeweils eine erste und eine zweite Lagerungsscheibe 52 angeordnet ist. Über die Lagerungsscheiben 52 ist der Betätigungshebel 5 verschwenkbar, das heißt drehbar, in der Leiteranschlussklemme 1 gelagert und kann dabei insbesondere auf der Oberfläche 30 der Sammelschiene 3 aufgelagert sein. In diesem Fall gleitet der Betätigungshebel 5 mit den Lagerungsscheiben 52 bei einer Verschwenkbewegung auf der Sammelschiene 3 ab.The actuating lever 5 is accessible for manual actuation on an actuating side 10 of the conductor connection terminal 1. The actuating lever 5 has a manual actuating element 50, on which the actuating lever 5 can be manually actuated. The actuating lever 5 extends from the manual actuating element 50 into an area in which the actuating lever 50 forks into a side cheek 51 arranged on the left and a side cheek 51 on the right. The side cheeks 51 can extend laterally, for example, beyond the holding frame 6. Respective spring actuating bodies are attached to the inner sides of the side cheeks 51 facing one another, on each of which a first and a second bearing disk 52 is arranged. The actuating lever 5 is pivotable, i.e. rotatable, in the conductor connection terminal 1 via the bearing disks 52 and can be supported in particular on the surface 30 of the busbar 3. In this case, the operating lever 5 slides with the bearing discs 52 on the busbar 3 during a pivoting movement.

Die Federbetätigungskörper weisen jeweils einen V-förmigen Einschnitt auf, durch den eine jeweilige Betätigungskante 53 gebildet ist. Die Betätigungskante 53 wirkt auf den Klemmschenkel 43 ein. Wird der Betätigungshebel 5 von der in Figur 1 dargestellten Geschlossenen-Stellung in eine Offen-Stellung verschwenkt, indem er um einen Winkel von ca. 90 Grad entgegen dem Uhrzeigersinn verschwenkt wird, wird durch die Betätigungskante 53 der Klemmschenkel 43 nach oben hin in Richtung des Anlageschenkels 41 ausgelenkt, wodurch das freie Ende 44 beziehungsweise die Klemmkante von der Sammelschiene 3 fortbewegt wird.The spring actuating bodies each have a V-shaped notch through which a respective actuating edge 53 is formed. The actuating edge 53 acts on the clamping leg 43. If the actuating lever 5 is released from the Figure 1 shown closed position into an open position by pivoting it counterclockwise through an angle of approximately 90 degrees, the clamping leg 43 is deflected upwards in the direction of the contact leg 41 by the actuating edge 53, whereby the free end 44 or the clamping edge is moved away from the busbar 3.

Die Figur 2 zeigt die Leiteranschlussklemme 1 in einer Draufsicht auf die Leitereinführseite 11. Die Sammelschiene 3 erstreckt sich in Querrichtung Q vollständig durch das Gehäuse 2 hindurch, das heißt der Aufnahmeraum 25 erstreckt sich ebenfalls vollständig durch die Leiteranschlussklemme 1 in der Querrichtung Q hindurch.The Figure 2 shows the conductor connection terminal 1 in a plan view of the conductor insertion side 11. The busbar 3 extends completely through the housing 2 in the transverse direction Q, i.e. the receiving space 25 also extends completely through the conductor connection terminal 1 in the transverse direction Q.

Die Figur 3 zeigt eine Schnittdarstellung der Leiteranschlussklemme 1 gemäß der Schnittlinie A-A der Figur 1. Hierdurch werden zusätzlich die bereits erläuterten Elemente verdeutlicht. Erkennbar ist insbesondere in der Figur 3, dass der Halterahmen 6 eine Aussparung 61 aufweist, die durch Stege 60, 63, 64 sowie nach unten hin, auf der dem Steg 60 gegenüberliegenden Seite der Aussparung 61 durch den sich anschließenden Bereich des Zugelements 62 begrenzt ist.The Figure 3 shows a sectional view of the conductor connection terminal 1 according to the section line AA of the Figure 1 This also clarifies the elements already explained. This is particularly evident in the Figure 3 that the holding frame 6 has a recess 61 which is delimited by webs 60, 63, 64 and downwards, on the side of the recess 61 opposite the web 60, by the adjoining region of the tension element 62.

Die Figur 4 zeigt eine alternative Ausführungsform der Rastbefestigung der Sammelschiene 3 mittels des Positionierelements 28. Bei der Ausführungsform der Figur 4 ist das Positionierelements 28 über einen U-förmig gebogenen Arm von dem ersten Gehäusebauteil 20 zu einer Seitenkante der Sammelschiene 3 geführt.The Figure 4 shows an alternative embodiment of the locking fastening of the busbar 3 by means of the positioning element 28. In the embodiment of the Figure 4 the positioning element 28 is guided via a U-shaped arm from the first housing component 20 to a side edge of the busbar 3.

Während bei den bisher erläuterten Ausführungsformen der Leiteranschlussklemme 1 die Einsetzöffnung 24 an der gleichen Gehäuseseite des Gehäuses 2 wie die Leitereinführungsöffnung 23 angeordnet ist, nämlich an der Leitereinführseite 11, wird anhand der in den Figuren 5 bis 7 dargestellten Ausführungsform der Leiteranschlussklemme 1 eine Variante erläutert, bei der die Einsatzöffnung 24 an der der Betätigungsseite 10 abgewandten Gehäuseseite des Gehäuses 2 angeordnet ist. Mit anderen Worten, bei der Ausführungsform der Figuren 5 bis 7 wird der Abschnitt der Sammelschiene 3 sozusagen von unten her in das Gehäuse 2 eingeführt.While in the previously explained embodiments of the conductor connection terminal 1 the insertion opening 24 is arranged on the same side of the housing 2 as the conductor insertion opening 23, namely on the conductor insertion side 11, the Figures 5 to 7 illustrated embodiment of the conductor connection terminal 1, a variant is explained in which the insertion opening 24 is arranged on the side of the housing 2 facing away from the actuating side 10. In other words, in the embodiment of the Figures 5 to 7 the section of the busbar 3 is inserted into the housing 2 from below, so to speak.

Erkennbar ist, dass in diesem Fall nur die Positionierelemente 26, 28 vorhanden sind. Die Sammelschiene 3 wird derart in den Aufnahmeraum 25 eingeführt, dass sie zunächst zwischen dem freien Ende 44 des Klemmschenkels 43 und dem Zugelement 62 eingeschoben wird und dann mittels einer Verkippbewegung hinter dem Positionierelement 28 eingerastet wird. Um eine ausreichende Beweglichkeit der mit dem Positionierelement 28 verbundenen Rastzunge zu gewährleisten, kann das Gehäuse 2, insbesondere das erste Gehäuseteil 20, eine längliche Einkerbung oder einen Einschnitt 29 aufweisen.It can be seen that in this case only the positioning elements 26, 28 are present. The busbar 3 is introduced into the receiving space 25 in such a way that it is first pushed between the free end 44 of the clamping leg 43 and the tension element 62 and is then locked in place behind the positioning element 28 by means of a tilting movement. In order to ensure sufficient mobility of the locking tongue connected to the positioning element 28, the housing 2, in particular the first housing part 20, can have an elongated notch or an incision 29.

Wie insbesondere durch die in Figur 6 verdeutlicht wird, muss das Positionierelement 28 nicht ein in der Querrichtung Q durchgehendes Rastelement sein, sondern kann durch zwei im Bereich der Seitenwände des Gehäuses 2 einzelne Rastelemente realisiert sein, welche durch einen Quersteg unterhalb der eingesetzten Sammelschiene 3 miteinander verbunden sind. In den so gebildeten Zwischenraum bzw. Durchbruch kann ein Werkzeug, beispielsweise ein Schraubendreher, eingesetzt werden, um das Positionierelement 28 auszulenken und die Rastverbindung zwischen dem Gehäuse 2 und der Sammelschiene aufzuheben, so dass die Leiteranschlussklemme 1 von der Sammelschiene abgenommen werden kann.As shown in particular by the Figure 6 As is made clear, the positioning element 28 does not have to be a locking element that runs through the transverse direction Q, but can be implemented by two individual locking elements in the area of the side walls of the housing 2, which are connected to one another by a crossbar below the inserted busbar 3. A tool, for example a screwdriver, can be inserted into the gap or opening thus formed in order to deflect the positioning element 28 and to remove the locking connection between the housing 2 and the busbar, so that the conductor connection terminal 1 can be removed from the busbar.

Im Übrigen ist die Leiteranschlussklemme gemäß den Figuren 5 bis 7 vergleichbar ausgebildet wie die zuerst beschriebene Ausführungsform.Furthermore, the conductor connection terminal is in accordance with Figures 5 to 7 similar in design to the first described embodiment.
