Die Drehachse des Betätigungshebels erstreckt sich quer zu der durch die Leitereinführungsöffnung definierten Leitereinführungsrichtung und liegt im Raum zwischen der von dem die Klemmstelle bildenden Stromschienenstückabschnitt aufgespannten Ebene und einer hierzu parallelen Ebene, in der die Klemmkante der Klemmfeder bei der durch Umschwenken des Betätigungshebels vollständig geöffneten Klemmfeder liegt.In a generic terminal of the type mentioned in each case two opposite actuating portions for receiving an associated clamping portion of the clamping spring of the associated Federkraftklemmanschlusses are at least partially provided in the space between the opposite actuating portions for each Federkraftklemmanschluss. On at least one operating portion of a pair of opposing operating portions for a spring terminal connection a contour for acting on the associated clamping spring is present. The axis of rotation of the actuating lever extends transversely to the conductor insertion direction defined by the conductor insertion opening and lies in the space between the clamped point of the conductor rail piece section plane and a plane parallel thereto, in which the clamping edge of the clamping spring in by pivoting the actuating lever fully open clamping spring is located.

Durch die Anordnung des Betätigungshebels mit seiner Drehachse in der Leitereinführungsöffnung oder in der Flucht der Leitereinführungsöffnung zur Klemmstelle hin erfolgt die Drehung des Betätigungshebels im Bereich der Klemmstelle oder im davor liegenden Raum. Dies hat den Vorteil, dass der Betätigungshebel überaus platzsparend im Isolierstoffgehäuse aufgenommen werden kann und dabei gleichzeitig als Wand des Leitereinführungskanals zur Führung eines elektrischen Leiters dient. Damit ersetzt der Betätigungshebel einen Teil der Führungswand für einen elektrischen Leiter der Leitereinführungsöffnung.Due to the arrangement of the actuating lever with its axis of rotation in the conductor insertion opening or in the alignment of the conductor insertion opening to the clamping point, the rotation of the actuating lever in the region of the nip or in front of it takes place space. This has the advantage that the operating lever can be accommodated extremely space-saving in the insulating housing and at the same time serves as a wall of the conductor insertion channel for guiding an electrical conductor. Thus, the operating lever replaces a part of the guide wall for an electrical conductor of the conductor insertion opening.

Das Verlegen der Drehachse in den Bereich der Klemmstelle bzw. in die Flucht der davor liegenden Leitereinführungsöffnung hat zudem den kinematischen Vorteil, dass die Betätigung der Klemmfeder relativ nah zur Drehachse erfolgt, was die Hebelkräfte auf das Isolierstoffgehäuse verringert.The laying of the axis of rotation in the region of the nip or in the alignment of the preceding conductor insertion opening also has the kinematic advantage that the actuation of the clamping spring takes place relatively close to the axis of rotation, which reduces the leverage forces on the insulating material.

Vorteilhafterweise stellt der Betätigungshebel beidseits eine seitliche Begrenzungswand zur Führung eines in Leitereinführungsrichtung in eine Leitereinführungsöffnung eingeführten elektrischen Leiters zu einer zugeordneten Klemmstelle bereit. Durch die beidseits eines jeweiligen Federkraftklemmanschlusses angeordneten Betätigungsabschnitte wird ein U-förmiger Betätigungshebel geschaffen, der verdrehfest ist und eine gute Drehlagerung im Isolierstoffgehäuse ermöglicht. Die mindestens eine Klemmfeder ist als eine U-förmig gebogene Klemmfeder ausgestaltet, deren freier Klemmabschnitt schräg in Richtung eines zugeordneten Stromschienenstücks weist. Mit Hilfe einer solchen U-förmig gebogenen Klemmfeder ist ein direktes Einklemmen eines elektrischen Leiters ohne vorheriges Öffnen der Klemmfeder mit dem zugeordneten Betätigungshebel möglich. Dies ist auch als Direktstecktechnik bekannt.Advantageously, the actuating lever on both sides of a lateral boundary wall for guiding an inserted in the conductor insertion direction in a conductor insertion opening electrical conductor to an associated nip ready. By arranged on both sides of a respective Federkraftklemmanschlusses actuating sections, a U-shaped actuating lever is provided, which is rotationally fixed and allows a good pivot bearing in Isolierstoffgehäuse. The at least one clamping spring is designed as a U-shaped bent clamping spring, the free clamping portion has obliquely in the direction of an associated busbar piece. With the help of such a U-shaped clamping spring direct clamping of an electrical conductor without prior opening of the clamping spring with the associated operating lever is possible. This is also known as direct plug-in technology.

Die Stromschiene im Abschnitt, der die Klemmstelle bildet, definiert unbeachtlich etwaiger Erhebungen für eine Kontaktkante eine erste Ebene, zu der eine zweite gedachte Ebene aufgespannt wird. Diese zweite Ebene ist derart von der Ebene des Stromschienenstücks beabstandet, dass die Klemmkante einer geöffneten Klemmfeder diese Ebene berührt. Der Zwischenraum zwischen den Ebenen bildet den bevorzugten Raum, in dem die Drehachse des Betätigungshebels sein sollte, um eine überaus kompakt bauende, mechanisch stabile Anschlussklemme bereitzustellen.The busbar in the section that forms the terminal point, defined irrelevant any elevations for a contact edge a first plane to which a second imaginary plane is spanned. This second plane is spaced from the plane of the bus bar piece in such a way that the clamping edge of an opened clamping spring touches this plane. The gap between the planes forms the preferred space in which the axis of rotation of the actuating lever should be in order to provide a very compact, mechanically stable connection terminal.

Besonders vorteilhaft ist es, wenn mindestens ein Betätigungshebel in einen angrenzend an einen Klemmabschnitt des zugeordneten Stromschienenstücks eingebrachten Ausschnitt des Stromschienenstücks eintaucht. Der Betätigungshebel beaufschlagt dann mit einem Betätigungsabschnitt einen über die Breite einer zugeordneten Klemmfeder gesehen neben dem Klemmabschnitt der Klemmfeder angeordnete Betätigungslasche, um die Klemmfeder zu öffnen. Mit Hilfe des Ausschnitts an einer Seitenkante des Stromschienenstücks gelingt es, den Betätigungshebel platzsparend aufzunehmen. Über die Breite des Stromschienenstücks und der zugeordneten Klemmfeder gesehen, ist dann an dem Klemmabschnitt der Klemmfeder unterhalb dieses Ausschnitts eine Betätigungslasche herausgestellt, die dann von dem Betätigungsabschnitt des Betätigungshebels bei Verschwenken des Betätigungshebels beaufschlagt wird, um die Klemmfeder zu öffnen. Die elektrische Kontaktierung eines elektrischen Leiters erfolgt dann angrenzend an diesen Ausschnitt des Stromschienenstücks bzw. über die Breite gesehen angrenzend an die Betätigungslasche durch den Klemmabschnitt der Klemmfeder und eine vorzugsweise vorgestellte Kontaktkante des Stromschienenstücks.It is particularly advantageous if at least one actuating lever dips into a cutout of the busbar section introduced adjacent to a clamping section of the associated busbar section. The actuating lever then acted upon with an actuating portion, as seen along the width of an associated clamping spring next to the clamping portion of the clamping spring arranged actuating tab to open the clamping spring. With the help of the cutout on one side edge of the busbar piece, it is possible to save the operating lever to save space. Seen over the width of the busbar piece and the associated clamping spring, an actuating tab is then exposed to the clamping portion of the clamping spring below this section, which is then acted upon by the operating portion of the actuating lever upon pivoting of the actuating lever to open the clamping spring. The electrical contacting of an electrical conductor is then adjacent to this section of the busbar piece or across the width seen adjacent to the actuating tab by the clamping portion of the clamping spring and a preferably presented contact edge of the busbar piece.

Die Betätigungslasche ist vorzugsweise von der Klemmfeder freigestellt, z.B. durch Freistanzen oder Freischneiden, und ragt schräg von dem Klemmabschnitt der Klemmfeder ab.The actuating tab is preferably free of the clamping spring, e.g. by free punching or free cutting, and protrudes obliquely from the clamping portion of the clamping spring.

Der mindestens eine Betätigungshebel hat vorzugsweise einen Betätigungsarm, der sich im geschlossenen Zustand des zugeordneten Federkraftklemmanschlusses in Leitereinsteckrichtung erstreckt. Damit endet das freie Ende des Betätigungsarms gegenüberliegend zur Leitereinstecköffnung im Bereich der Rückseite der Anschlussklemme. Damit ist eine sehr kompakte Bauweise der Anschlussklemme möglich.The at least one actuating lever preferably has an actuating arm, which extends in the closed state of the associated Federkraftklemmanschlusses in Leitereinsteckrichtung. Thus ends the free end of the actuating arm opposite to the conductor insertion in the back of the terminal. This makes a very compact design of the terminal possible.

Denkbar ist aber auch, dass der mindestens eine Betätigungshebel einen Betätigungsarm hat, der sich an der Unterseite oder der Oberseite der Anschlussklemme in Leitereinsteckrichtung oder entgegengesetzt hierzu erstreckt. Für möglichst kompakt bauende Varianten der Anschlussklemme sind insbesondere Kombinationen denkbar, bei denen sich Betätigungsarme der Betätigungshebel alternierend in Leitereinsteckrichtung und entgegengesetzt hierzu erstrecken bzw. alternierend auf der Unterseite und Oberseite in gleiche Richtungen oder in alternierend in entgegengesetzte Richtungen erstrecken.It is also conceivable that the at least one operating lever has an actuating arm which extends on the underside or the top of the terminal in Leiterereinsteckrichtung or opposite thereto. Combinations of the connecting terminal which are as compact as possible are conceivable, in particular, in which actuating arms of the actuating lever extend alternately in the conductor insertion direction and in the opposite direction, or extend alternately on the underside and the upper side in the same directions or in alternating directions in opposite directions.

Diese Ausführungsformen sind insbesondere abhängig von der konkreten Kombination von Federkraftanschlussklemmen und deren räumliche Lage zueinander.These embodiments are particularly dependent on the specific combination of spring terminals and their spatial position to each other.

In einer diesbezüglich bevorzugten Ausführungsform hat die Anschlussklemme mindestens ein Paar voneinander gegenüberliegenden Federkraftanschlussklemmen mit aufeinander zulaufenden Leitereinführungsöffnungen an der einander gegenüberliegenden Vorderseite und Rückseite der Anschlussklemme. Bei dieser Ausführungsform können elektrische Leiter somit sowohl von der Vorderseite als auch von der Rückseite der Anschlussklemme in entgegengesetzte Leitereinführungsrichtungen eingesteckt und mit zugeordneten Federkraftanschlussklemmen kontaktiert werden. Jede Federkraftanschlussklemme eines solchen Paares mit einander gegenüberliegenden, gegebenenfalls versetzten Leitereinführungsöffnungen, hat jeweils einen Betätigungshebel mit einem Betätigungsarm, deren Betätigungsarme in entgegengesetzte Richtungen voneinander weisen.In a preferred embodiment, the terminal has at least one pair of opposed spring terminals with converging conductor entry openings at the opposite front and back of the terminal. In this embodiment, electrical conductors can thus be plugged in from both the front and the back of the terminal in opposite conductor insertion directions and contacted with associated spring terminals. Each spring terminal of such a pair with opposing, optionally offset conductor insertion openings, each having an actuating lever with an actuating arm, the actuating arms facing each other in opposite directions.

Die Betätigungsarme werden dabei vorzugsweise in dem Raum zwischen zwei Leitereinführungsöffnungen oberhalb bzw. unterhalb der Leitereinführungsöffnungen an der Oberseite oder Unterseite der Anschlussklemme in zugeordnete Vertiefungen des Isolierstoffgehäuses aufgenommen.The actuating arms are preferably received in the space between two conductor insertion openings above or below the conductor insertion openings at the top or bottom of the terminal in associated recesses of the insulating material.

Bei dieser Ausführungsform ist es besonders vorteilhaft, wenn die Betätigungsarme eines Paares von Betätigungshebeln auf der gleichen Seite oder alternativ auf einander gegenüberliegenden Seiten der Anschlussklemme angeordnet sind.In this embodiment, it is particularly advantageous if the actuating arms of a pair of actuating levers are arranged on the same side or alternatively on opposite sides of the connecting terminal.

So zeigt Figur 1 eine Ausführungsform einer mehrreihigen Anschlussklemme 1 in Form einer Dosenklemme. Diese Anschlussklemme 1 hat mehrere nebeneinander liegende und elektrisch leitend miteinander verbundene Federkraftklemmanschlüsse 3 von denen der linke sichtbar ist. Es ist erkennbar, dass eine Klemmfeder 4 in ein Stromschienenstück 5 angehängt ist. Die Klemmfeder 4 ist U-förmig gebogen, so dass ein Klemmabschnitt 6 mit einer Klemmkante am freien Ende zur Bildung einer Klemmstelle gegen den Stromschienenstückabschnitt 5a ragt. Im unbelasteten Zustand ohne eingeklemmten elektrischen Leiter liegt die Klemmkante an dem Stromschienenstückabschnitt 5a.So shows FIG. 1 an embodiment of a multi-row terminal 1 in the form of a terminal box. This terminal 1 has several side by side lying and electrically conductive interconnected Federkraftklemmanschlüsse 3 of which the left is visible. It can be seen that a clamping spring 4 is attached in a busbar piece 5. The clamping spring 4 is bent in a U-shape, so that a clamping section 6 projects with a clamping edge at the free end to form a clamping point against the busbar section 5a. In the unloaded state without clamped electrical conductors, the clamping edge is located on the busbar section 5a.

Jeder Federkraftklemmanschluss 3 stellt eine Klemmstelle durch einen am freien, beweglichen Ende der Klemmfeder gebildeten Klemmabschnitt 6 und insbesondere durch die Klemmkante am freien Ende der Klemmfeder 4 sowie an dem dem Klemmabschnitt 6 gegenüberliegenden Stromschienenstückabschnitt 5a bereit. Zum Einführen eines elektrischen Leiters zu der Klemmstelle ist für jeden Federkraftklemmanschluss 3 eine zugeordnete Leitereinführungsöffnung 7 in das Isolierstoffgehäuse eingebracht. Die Leitereinführungsöffnung 7 hat einen Durchmesser, der an den größtmöglichen zulässigen Querschnitt mitsamt Isolierstoffmantel eines elektrischen Leiters angepasst ist.Each spring terminal connection 3 provides a nip by a clamping section 6 formed at the free, movable end of the clamping spring and in particular by the clamping edge at the free end of the clamping spring 4 and at the busbar section 5a opposite the clamping section 6. For introducing an electrical conductor to the terminal point, an associated conductor insertion opening 7 is introduced into the insulating material housing for each spring terminal connection 3. The conductor insertion opening 7 has a diameter which is adapted to the maximum permissible cross-section together with insulating jacket of an electrical conductor.

Zum Öffnen der Klemmfedern 4 hat jeder Federkraftklemmanschluss 3a, 3b einen Betätigungshebel 8 mit einem Betätigungsabschnitt 9 sowie einen daran angrenzenden, sich in einer Längsrichtung erstreckenden Betätigungsarm 10.To open the clamping springs 4, each spring terminal connection 3a, 3b has an actuating lever 8 with an actuating portion 9 and an actuating arm 10, which adjoins it and extends in a longitudinal direction.

Die Betätigungshebel 8 sind in Schließstellung der Klemmstellen gezeigt. Die Betätigungshebel 8 können um etwa 90° von der Schließstellung zur Offenstellung umgeschwenkt werden. Hierzu sind die Betätigungshebel 8 mit ihren Betätigungsabschnitten 9 und insbesondere der Drehachse D, um die der jeweilige Betätigungshebel 8 schwenkbar im Isolierstoffgehäuse 2 der Anschlussklemme gelagert ist, im Raum der zugeordneten Leitereinführungsöffnung 7 bzw. in Leitereinführungsrichtung L zur Klemmstelle in der weiterführenden Verlängerung der Leitereinführungsöffnung 7 angeordnet.The actuating lever 8 are shown in the closed position of the clamping points. The actuating lever 8 can be pivoted about 90 ° from the closed position to the open position. For this purpose, the actuating lever 8 with its operating sections 9 and in particular the axis of rotation D, about which the respective operating lever 8 is pivotally mounted in the insulating 2 of the terminal, in the space of the associated conductor insertion opening 7 and in conductor insertion direction L to the nip in the continuing extension of the conductor insertion opening. 7 arranged.

Erkennbar ist weiterhin, dass in Richtung der Breite der Klemmfeder 4 gesehen neben dem Klemmabschnitt 6 jeweils eine Betätigungslasche 11 freigestellt ist und von dem Klemmabschnitt 6 schräg abragt. Eine angepasste Kontur des Betätigungsabschnitts 9 des zugeordneten Betätigungshebels 8 beaufschlagt beim Verschwenken des Betätigungshebels 8 von der Schließstellung zur Offenstellung diese Betätigungslasche 11 während des Bewegungsablaufs mindestens teilweise. Auf diese Weise wird der Klemmabschnitt 6 der Klemmfeder 4 von dem angrenzenden, die Klemmstelle bildenden Stromschienenstückabschnitt 5a weg bewegt, um die Klemmfeder 4 zu öffnen.It can also be seen that, viewed in the direction of the width of the clamping spring 4, in each case one actuating lug 11 is exposed next to the clamping section 6 and protrudes obliquely from the clamping section 6. An adapted contour of the actuating portion 9 of the associated actuating lever 8 acts upon pivoting of the actuating lever 8 from the closed position to the open position, this actuating tab 11 during the movement at least partially. In this way, the clamping portion 6 of the clamp spring 4 is moved away from the adjacent busbar piece portion 5a forming the nip to open the clamp spring 4.

Die Klemmfeder 4 kann bei dieser Ausführungsform beidseits des Klemmabschnitts 6 Betätigungslaschen 11 haben.The clamping spring 4 can in this embodiment on both sides of the clamping portion 6 actuating tabs 11 have.

Deutlich wird, dass der die Klemmstelle bildende Stromschienenstückabschnitt 5a an seinem freien Ende einen Klemmvorsprung 18 hat, durch den eine hinsichtlich seiner Fläche reduzierte, definierte Anlagefläche für einen elektrischen Leiter geschaffen wird. Die Klemmkraft der Klemmfeder 4 wird dann über den elektrischen Leiter auf diese durch den Klemmvorsprung 18 definierte Klemmfläche konzentriert, so dass der Flächendruck im Vergleich zu einer planaren Auflagefläche erhöht ist. Deutlich wird weiterhin, dass das freie Ende des die Klemmstelle bildenden Stromschienenstückabschnitts 5a schräg nach oben abgewinkelt ist, um eine Führung für einen elektrischen Leiter zur Klemmkante 18 bereitzustellen.It is clear that the conductor rail piece section 5a forming the clamping point has at its free end a clamping projection 18, by means of which a defined contact surface, reduced in terms of its area, is created for an electrical conductor. The clamping force of the clamping spring 4 is then concentrated via the electrical conductor to this clamping surface defined by the clamping projection 18, so that the surface pressure is increased in comparison to a planar support surface. It is also clear that the free end of the terminal point forming busbar section 5a is angled obliquely upwards to provide a guide for an electrical conductor to the clamping edge 18.

Der die Klemmstelle bildende Stromschienenstückabschnitt 5a kann optional (nicht dargestellt) seitlich benachbart zur Klemmkante 18 einen Ausschnitt in Form einer Einsenkung haben, in die der Betätigungsabschnitt 9 des Betätigungshebels 8 eintaucht. Über die Breite der Klemmfeder 4 ist dann unterhalb dieses Ausschnitts 19 die Betätigungslasche 11 vom Klemmabschnitt 6 der Klemmfeder 4 freigestellt und erstreckt sich in Richtung der Leitereinführungsrichtung L.The conductor rail piece section 5a forming the clamping point can optionally (not shown) have a cutout in the form of a depression laterally adjacent to the clamping edge 18, into which the actuating section 9 of the actuating lever 8 dips. Over the width of the clamping spring 4 is below this section 19, the actuating tab 11 is released from the clamping portion 6 of the clamping spring 4 and extends in the direction of the conductor insertion direction L.

Deutlich wird, dass die Seitenwände des Betätigungsabschnitts 9 des Betätigungshebels 8 für einen zur Klemmstelle eingeführten elektrischen Leiter eine seitliche Begrenzungswand bilden, die zur Führung des elektrischen Leiters zur Klemmstelle genutzt wird.It is clear that the side walls of the actuating portion 9 of the actuating lever 8 form a lateral boundary wall for an electrical conductor inserted into the terminal point, which is used to guide the electrical conductor to the terminal point.

Die Stromschienenstücke 5 der in Blickrichtung schräg nach rechts hinten nebeneinander angeordneten Federkraftklemmanschlüsse 3 können elektrisch leitend miteinander verbunden sein. Denkbar ist aber auch eine Ausführungsform der Anschlussklemme 1, bei der jeweils zwei nebeneinander liegende Federkraftklemmanschlüsse 3 elektrisch leitend miteinander verbunden sind und zwei oder drei Paare solcher elektrisch leitend miteinander verbundenen Federkraftklemmanschlüsse 3 vorgesehen sind. Damit können jeweils zwei Leiter für einen einphasigen Spannungsversorgungsanschluss mit den Anschlüssen L (Phase), N (Neutralleiter) und PE (Erde) jeweils miteinander verbunden werden, so dass eine Netzanschlussklemme gebildet wird.The busbar pieces 5 of the obliquely to the right rear juxtaposed spring terminal connections 3 can be electrically connected to each other. It is also conceivable, however, an embodiment of the terminal 1, in which two juxtaposed spring terminal connections 3 are electrically connected to each other and two or three pairs of such electrically conductive interconnected Federkraftklemmanschlüsse 3 are provided. In each case two conductors for a single-phase power supply connection with the connections L (phase), N (neutral conductor) and PE (earth) can be connected to one another, so that a mains connection terminal is formed.

Deutlich wird, dass die Betätigungshebel 8 jeweils neben den Klemmstellen, d.h. neben dem Stromschienenstückabschnitt 5a und dem Klemmabschnitt 6 unmittelbar hinter dem Ende der im Isolierstoffgehäuse 2 ausgeformten Leitereinführungsöffnung 7 angeordnet sind. Die Betätigungsabschnitte 9 der Betätigungshebel 8 bilden eine Fortführung der Wand der jeweiligen Leitereinführungsöffnung 7, um einen elektrischen Leiter zur Klemmstelle zu führen. Jeder Betätigungsabschnitt 9 wirkt mit einer zugeordneten Betätigungslasche 11 der Klemmfeder 4 zusammen. Die Drehachse der Betätigungshebel 8 liegt unterhalb des Stromschienenstückabschnitts 5 im Bereich der Klemmstelle. Die Drehachse erstreckt sich quer zur Leitereinsteckrichtung, die durch die Erstreckungsrichtung der Leitereinführungsöffnung 7 vorgegeben ist.It will be appreciated that the actuation levers 8 are respectively adjacent to the nip points, i. are arranged immediately behind the end of the formed in the insulating housing 2 conductor insertion opening 7 next to the busbar piece portion 5a and the clamping portion 6. The operating portions 9 of the operating lever 8 form a continuation of the wall of the respective conductor insertion opening 7, to guide an electrical conductor to the nip. Each actuating portion 9 cooperates with an associated actuating tab 11 of the clamping spring 4. The axis of rotation of the actuating lever 8 is below the busbar piece portion 5 in the region of the clamping point. The axis of rotation extends transversely to the Leiterereinsteckrichtung, which is predetermined by the extension direction of the conductor insertion opening 7.

Deutlich wird auch, dass sich die Betätigungsarme 10 entgegengesetzt zur Leitereinsteckrichtung L erstrecken und an der Oberseite des Isolierstoffgehäuses 2 angeordnet sind. Die freien Enden der Betätigungsarme 10 liegen im Bereich der Vorderseite. Die freien Enden der Betätigungsarme 10 sind von den Begrenzungswänden der Leitereinführungsöffnung 7 bzw. dem Isolierstoffgehäuse 2 derart beabstandet, dass sie von Hand gegriffen und verschwenkt werden können.It is also clear that the actuating arms 10 extend opposite to the conductor insertion direction L and at the top of the insulating material 2 are arranged. The free ends of the actuating arms 10 are in the region of the front. The free ends of the actuating arms 10 are spaced from the boundary walls of the conductor insertion opening 7 and the insulating housing 2 such that they can be grasped and pivoted by hand.

Erkennbar ist weiterhin, dass die Betätigungshebel 8 in Vertiefungen des Isolierstoffgehäuses 2 für zur Aufnahme eines Teils des Betätigungsarmes 10 aufgenommen ist. Dabei erstreckt sich der Betätigungsarm 10 in der Schließstellung entgegengesetzt zur Leitereinführungsrichtung L zur jeweiligen Vorderseite der zugehörigen Leitereinführungsöffnung 7 des Isolierstoffgehäuses 2.It can also be seen that the actuating lever 8 is received in recesses of the insulating housing 2 for receiving a part of the actuating arm 10. In this case, the actuating arm 10 extends in the closed position opposite to the conductor insertion direction L to the respective front side of the associated conductor insertion opening 7 of the insulating material. 2

Optional ist noch eine Ausführungsform denkbar, bei der der Betätigungsarm 10 um 180° gedreht ist und in der Schließstellung in Leitereinführungsrichtung L weist.Optionally, an embodiment is conceivable in which the actuating arm 10 is rotated by 180 ° and points in the closed position in the conductor insertion direction L.

Aus Figur 1 wird insbesondere anhand der mittig dargestellten Leitereinführungsöffnungen 7 mit dem sich daran anschließenden Betätigungshebel 8 deutlich, dass ein Betätigungshebel 8 bei dem Ausführungsbeispiel jeweils zum Öffnen von zwei nebeneinander liegenden Federkraftklemmanschlüssen 3 vorgesehen ist. Alternativ kann auch pro Klemmstelle jeweils ein Betätigungshebel 8 vorgesehen sein.Out FIG. 1 is in particular on the basis of the conductor insertion openings 7 shown in the center with the adjoining operating lever 8 clearly that an operating lever 8 is provided in the embodiment in each case for opening two juxtaposed Federkraftklemmanschlüsse 3. Alternatively, one operating lever 8 can also be provided per clamping point.

Figur 2 lässt eine perspektivische Ansicht eines solchen Betätigungshebels 8 von der Vorderseite erkennen. Deutlich wird aber dabei, dass im mittleren, zentralen Bereich eine Öffnung 24 vorhanden ist, in die eine Führungswand des Isolierstoffgehäuses eintaucht, um den Betätigungshebel 8 kippsicher im Isolierstoffgehäuse 2 zu führen. Die Öffnung 24 ist im oberen Bereich von einem umlaufenden Kragen 25 umgeben. Dieser dient zur Verstärkung und Versteifung des Betätigungshebels 8. FIG. 2 lets a perspective view of such an actuating lever 8 from the front recognize. It is clear, however, that in the middle, central region, an opening 24 is present, into which a guide wall of the insulating housing dips in order to guide the operating lever 8 tilt-proof in the insulating housing 2. The opening 24 is surrounded in the upper region by a circumferential collar 25. This serves to reinforce and stiffen the operating lever eighth

Deutlich ist weiterhin, dass der Betätigungshebel 8 an seinen beiden seitlichen äußeren Enden einen als Lager dienenden Drehzapfen 22 hat. Die Drehzapfen 22 sind in korrespondierende Öffnungen im Isolierstoffgehäuse 2 aufgenommen.It is also clear that the actuating lever 8 has a serving as a bearing pivot pin 22 at its two lateral outer ends. The pivot pins 22 are received in corresponding openings in the insulating housing 2.

Erkennbar ist weiterhin, dass für jeden Federkraftklemmanschluss 3 jeweils zwei einander gegenüberliegende Betätigungsabschnitte 9 vorgesehen sind, so dass ein elektrischer Leiter beidseits an diesen Betätigungsabschnitten 9 zur Klemmstelle geführt wird, nachdem der elektrische Leiter von der seitlich umlaufend begrenzten Leitereinführungsöffnung 7 zur Klemmstelle hin aus der Leitereinführungsöffnung 7 austritt.It can also be seen that two mutually opposite actuating sections 9 are provided for each spring terminal connection 3, so that an electrical conductor is guided on both sides of these actuating sections 9 to the terminal point after the electrical conductor from the laterally circumscribed conductor insertion opening 7 to the clamping point from the conductor insertion opening 7 exit.

Die einander gegenüberliegenden Betätigungsabschnitte 9 dienen somit als Fortsetzung der Leitereinführungsöffnung 7.The opposing actuating portions 9 thus serve as a continuation of the conductor insertion opening. 7

An den einander gegenüberliegenden Seitenkanten der Betätigungsarme 10 können die Betätigungshebel 8 Rastnuten 26 oder vorspringende Rastzapfen haben, um den Betätigungshebel im geschlossenen Zustand mit dem Isolierstoffgehäuse 2 zu verrasten und ein unbeabsichtigtes Öffnen der Betätigungshebel 8 mit reduzierter Kraft zu verhindern.At the opposite side edges of the actuating arms 10, the actuating lever 8 locking grooves 26 or projecting locking pins have to lock the operating lever in the closed state with the insulating 2 and to prevent inadvertent opening of the operating lever 8 with reduced force.

Figur 3 lässt den Betätigungshebel aus Figur 2 in der Rückseitenansicht erkennen. Deutlich wird die als Schlitz ausgeführte Öffnung 24 im Zentrum des Betätigungshebels 8. FIG. 3 lets go of the operating lever FIG. 2 in the back view. The opening 24, which is designed as a slot, becomes clear in the center of the actuating lever 8.

Erkennbar ist auch der an der Oberseite des Betätigungsarms 10 umlaufende Kragen 25, der in die Wände übergeht, die die Betätigungsabschnitte 9 mit der dazwischen liegenden Öffnung 24 (Schlitz) bilden.Visible is also the circumferential on the top of the actuating arm 10 collar 25, which merges into the walls which form the actuating portions 9 with the intermediate opening 24 (slot).

Figur 4 lässt eine perspektivische Ansicht des Betätigungshebels aus Figur 2 und 3 von der Unterseite erkennen. Dabei wird deutlich, dass die Öffnung 24 im unteren Bereich wieder geschlossen ist. Erkennbar ist auch, dass die Wände, die die Betätigungsabschnitte 9 bilden, über Stege 27 an der Unterseite des Betätigungsarms 10 in diesen übergehen, um so den Betätigungsarm 10 zu versteifen und ein Ausfedern relativ zu den Betätigungsabschnitten 9 zu verhindern. Die Betätigungsabschnitte 9 haben eine auf die Drehachse D abgestimmte Kontur derart, dass der geöffnete Betätigungshebel 8 in einer Übertotpunktlage selbsthaltend bleibt. FIG. 4 leaves a perspective view of the actuating lever FIG. 2 and 3 recognize from the bottom. It is clear that the opening 24 is closed again in the lower area. It can also be seen that the walls which form the actuating sections 9 pass over webs 27 on the underside of the actuating arm 10, so as to stiffen the actuating arm 10 and prevent rebounding relative to the actuating sections 9. The actuating sections 9 have a contour tuned to the axis of rotation D such that the opened actuating lever 8 remains self-holding in an over-center position.

Erkennbar ist weiterhin, dass zusätzlich zu den Drehzapfen 22 im mittleren Bereich eine Führungsfläche 22a zur Lagerung vorhanden ist.It can also be seen that, in addition to the pivot pins 22, a guide surface 22a is provided for storage in the middle region.

Figur 5 lässt eine weitere Ausführungsform einer Anschlussklemme 1 mit mehreren in Blickrichtung hintereinander angeordneten Federkraftklemmanschlüssen 3 und zugeordneten Betätigungshebeln 8 erkennen. In der Darstellung ist der Betätigungshebel 8 in der Schließstellung gezeigt, bei der die Klemmfeder 4 des Federkraftklemmanschlusses 3 geschlossen ist. FIG. 5 shows a further embodiment of a terminal 1 with a plurality of view in the direction successively arranged spring terminal connections 3 and associated actuating levers 8 recognize. In the illustration, the operating lever 8 is shown in the closed position, in which the clamping spring 4 of the spring terminal connection 3 is closed.

Figur 6 zeigt denselben Betätigungshebel 8 in der Offenstellung, bei der der Federkraftklemmanschluss 3 geöffnet ist. FIG. 6 shows the same operating lever 8 in the open position, in which the spring force clamping connection 3 is open.

Deutlich wird, dass der Betätigungshebel 8 mit seinen Betätigungsabschnitten 9 unmittelbar hinter der Leitereinführungsöffnung 7 wiederum beidseits seitlich neben dem Stromschienenstück 5 bzw. dem die Klemmstelle bildenden Stromschienenstückabschnitt 5a angeordnet ist. Wiederum liegt die Drehachse D in der Leitereinführungsöffnung 7 bzw. direkt dahinter und in Leitereinsteckrichtung L gesehen kurz vor der Klemmstelle sowie unterhalb des die Klemmstelle bildenden Stromschienenstückabschnitt 5a. Die Betätigungsarme 10 der Betätigungshebel 8 sind in Leitereinsteckrichtung L von den Leitereinführungsöffnungen 7 weg in Richtung der Rückseite der Anschlussklemme 1 gerichtet. Damit wird ein sehr kompakter Aufbau der Anschlussklemme 1 bei einfacher und zuverlässiger Betätigung des Federkraftklemmanschlusses 3 ermöglicht.It is clear that the actuating lever 8 with its actuating portions 9 immediately behind the conductor insertion opening 7 again on both sides laterally next to the busbar piece 5 and the terminal point forming busbar section 5a is arranged. Again, the axis of rotation D is in the conductor insertion opening 7 or directly behind and in Leiterereinsteckrichtung L seen just before the terminal point and below the terminal point forming busbar section 5a. The actuating arms 10 of the actuating lever 8 are directed in Leitereinsteckrichtung L of the conductor insertion openings 7 away towards the back of the terminal 1. This makes a very compact construction of the terminal 1 easier and reliable operation of the spring force terminal 3 allows.

Erkennbar ist weiterhin, dass an der Vorderseite des Isolierstoffgehäuses 2 im unteren Bereich eine Prüföffnung 28 vorgesehen ist, die zur Klemmfeder 4 geöffnet ist. Auf diese Weise kann das an dem Federkraftklemmanschluss anliegenden Spannungspotential mit Hilfe eines in die Prüföffnung 28 eingeführten Prüfstiftes gemessen werden.It can also be seen that a test opening 28, which is open to the clamping spring 4, is provided on the front side of the insulating material housing 2 in the lower region. In this way, the voltage potential applied to the spring terminal connection can be measured by means of a test pin inserted into the test opening 28.

Figur 7 lässt eine Seitenansicht der Betätigungshebel 8 der Anschlussklemme 1 aus Figur 5 und 6 erkennen. Deutlich wird, dass der Betätigungsarm 10 von den Betätigungsabschnitten 9 zunächst schräg nach links und dann in Leitereinsteckrichtung L wegragt. Erkennbar ist auch das Querstück 10c am unteren freien Ende des Betätigungsarms 10. FIG. 7 leaves a side view of the operating lever 8 of the terminal 1 FIGS. 5 and 6 detect. It is clear that the actuating arm 10 projects from the operating sections 9 first obliquely to the left and then in Leitereinsteckrichtung L. Visible is also the crosspiece 10 c at the lower free end of the actuating arm 10th

Durch eine geeignete Kontur des Betätigungsabschnitts in Abstimmung mit der Lage der Drehachse D kann ein Selbsthalten des geöffneten Betätigungshebels 8 in einer Übertotpunktlage erreicht werden.By means of a suitable contour of the actuating section in coordination with the position of the axis of rotation D, self-holding of the opened actuating lever 8 in an over-center position can be achieved.

Die Betätigungsabschnitte 9 haben hierzu z. B. eine Nase 30, die auf die Lage der Drehachse so abgestimmt ist, dass der geöffnete Betätigungshebel 8 in einer Übertotpunktlage selbsthaltend verharrt.The operating sections 9 have z. B. a nose 30, which is tuned to the position of the axis of rotation so that the open operating lever 8 remains self-holding in an over-center position.

Figur 8 lässt eine Aufsicht auf den Betätigungsarm aus Figur 11 von unten erkennen. Dabei wird der Aufbau des Betätigungsarms 10 mit zwei Armabschnitten 10a, 10b und dem die Armabschnitte 10a, 10b am freien Ende verbindenen Querstück 10c deutlich. FIG. 8 11 shows a top view of the actuating arm from FIG. 11 from below. In this case, the structure of the actuating arm 10 with two arm portions 10a, 10b and the arm portions 10a, 10b connecting at the free end crosspiece 10c clearly.

Erkennbar ist auch, dass seitlich an den Außenseiten der Betätigungsabschnitte 9 Drehzapfen 22 herausragen, die in entsprechende Vertiefungen des Isolierstoffgehäuses 2 der Anschlussklemme 1 gelagert sind.It can also be seen that laterally on the outer sides of the actuating sections 9 pivot pins 22 project, which are mounted in corresponding recesses of the insulating housing 2 of the connection terminal 1.

Erkennbar ist weiterhin, dass die einander gegenüberliegenden Innenseiten der Betätigungsabschnitte 9 zum freien Ende hin schräg gestellt sind und Einführungsschrägen 29 zum Führen eines elektrischen Leiters ohne störende Kanten haben.It can also be seen that the opposing inner sides of the actuating portions 9 are inclined towards the free end and have insertion bevels 29 for guiding an electrical conductor without disturbing edges.

Alternativ zu der dargestellten Dosenklemme sind weitere Varianten denkbar. Dies gilt insbesondere für Varianten von Anschlussklemmen, bei denen über die Länge der Anschlussklemme gesehen zwei hintereinander liegende Federkraftklemmanschlüsse 3 vorgesehen sind. Zum Einsparen von Bauraum kann es von Vorteil sein, wenn die Betätigungshebel 8 alternierend über die Breite gesehen an der Oberseite und Unterseite herausragen.As an alternative to the illustrated terminal box, further variants are conceivable. This is especially true for variants of terminals, where seen over the length of the terminal seen two consecutive Federkraftklemmanschlüsse 3 are provided. To save space, it may be advantageous if the operating lever 8 seen alternately over the width protrude at the top and bottom.

Denkbar ist dabei auch eine Variante, bei der die Betätigungsarme 10 alternierend einerseits in Leitereinführungsrichtung und bei dem danebenliegenden Federkraftklemmanschluss 3 entgegengesetzt zur Leitereinführungsrichtung L aus der Rückseite bzw. Vorderseite herausragen.Conceivable here is also a variant in which the actuating arms 10 protrude alternately on the one hand in the conductor insertion direction and the adjacent spring terminal connection 3 opposite to the conductor insertion direction L from the back or front.

Dabei ist noch eine Variante denkbar, dass nicht nur die Richtung der Betätigungsarme 10 alternierend wechseln, sondern auch die Ausrichtung der Betätigungshebel alternierend so sind, dass diese aus der Oberseite und benachbart aus der Unterseite des Isolierstoffgehäuses 2 herausragen bzw. in Vertiefungen an der Oberseite und alternierend der Unterseite aufgenommen sind.In this case, another variant is conceivable that not only change the direction of the actuating arms 10 alternately, but also the orientation of the actuating lever are alternately so that they protrude from the top and adjacent from the bottom of the insulating housing 2 or in recesses on the top and alternately the bottom are added.
