Description

Die Erfindung betrifft eine Leiteranschlussklemme zum Anschließen eines elektrischen Leiters.The invention relates to a conductor terminal for connecting an electrical conductor.

Eine Leiteranschlussklemme mit einem Kontakteinsatz ist bspw. aus der DE 10 2005 014 075 B3 bekannt. Aus der JP H04 82174 A und der JP H07 22084 A sind jeweils Leiteranschlussklemmen ohne Betätigungselement bekannt. JP H04 82174 A offenbart eine Leiteranschussklemme nach dem Oberbegriff des Anspruchs 1.A conductor terminal with a contact insert is, for example, from the DE 10 2005 014 075 B3 known. From the JP H04 82174 A and the JP H07 22084 A are each conductor terminals without actuator known. JP H04 82174 A discloses a conductor terminal according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, eine Leiteranschlussklemme sowie einen Kontakteinsatz dafür weiter zu verbessern.The object of the invention is to further improve a conductor connection terminal and a contact insert for it.

Diese Aufgabe wird gelöst durch eine Leiteranschlussklemme nach Anspruch 1, mit wenigstens einem Gehäuse und wenigstens einer Klemmfeder, die einen zur Fixierung der Klemmfeder dienenden Anlageschenkel, einen sich an den Anlageschenkel anschließenden und vom Anlageschenkel fortgebogenen Verbindungsschenkel, einen sich an den Verbindungsschenkel anschließenden Federbogen und einen sich an den Federbogen anschließenden Klemmschenkel aufweist, der zum Festklemmen eines elektrischen Leiters an einer Klemmstelle eingerichtet ist, und wobei der Verbindungsschenkel wenigstens einen Leiter-Durchgangsöffnungsbereich aufweist, durch den ein elektrischer Leiter von einer Leitereinführungsöffnung des Gehäuses durch den Leiter-Durchgangsöffnungsbereich zur Klemmstelle geführt werden kann, wobei die Leiteranschlussklemme ein Betätigungselement zum Betätigen des Klemmschenkels aufweist, das einen außerhalb des Gehäuses manuell betätigbaren manuellen Betätigungsbereich und einen zum Auslenken des Klemmschenkels eingerichteten Betätigungsstößel aufweist, wobei der Betätigungsstößel sich durch einen Betätigungsstö-ßel-Durchgangsöffnungsbereich im Verbindungsschenkel hindurcherstreckt. Der Be-Die Erfindung betrifft eine Leiteranschlussklemme zum Anschließen eines elektrischen Leiters. tätigungsstößel-Durchgangsöffnungsbereich im Verbindungsschenkel kann bspw. als fensterartige Durchgangsöffnung ausgebildet sein.This object is achieved by a conductor connection terminal according to claim 1, with at least one housing and at least one clamping spring, which has a contact leg serving to fix the clamping spring, a connecting leg adjoining the contact leg and bent away from the contact leg, a spring bow adjoining the connecting leg and a has a clamping limb adjoining the spring bow, which is designed for clamping an electrical conductor at a clamping point, and wherein the connecting limb has at least one conductor through-opening area, through which an electrical conductor can be guided from a conductor insertion opening of the housing through the conductor through-opening area to the clamping point wherein the conductor terminal has an actuating element for actuating the clamping leg, which has a manual actuating area that can be actuated manually outside the housing and an actuating plunger designed to deflect the clamping leg, the actuating plunger extending through an actuating plunger through-opening area in the connecting leg. The invention relates to a conductor connection terminal for connecting an electrical conductor. actuation tappet through-opening area in the connecting leg can be designed, for example, as a window-like through-opening.

Der Klemmschenkel befindet sich somit in Leitereinsteckrichtung gesehen auf der dem Verbindungsschenkel abgewandten Seite. Auf diese Weise kann eine Leiteranschlussklemme mit rückwärtiger Leitereinführungsmöglichkeit in fertigungstechnischer und anwendungsfreundlicher Weise weiterentwickelt werden. Als rückwärtige Leitereinführungsmöglichkeit bezeichnet man dabei eine Ausgestaltung einer Leiteranschlussklemme, bei der der elektrische Leiter von der Federbogen-Seite der Klemmfeder eingeführt wird und sich eben durch einen Teil der Klemmfeder hindurcherstreckt. Die vorliegende Erfindung hat den Vorteil, dass eine solche Leiteranschlussklemme auf einfache und komfortable Weise manuell betätigt werden kann. Sofern das Betätigungselement im nicht betätigten Zustand aus dem Gehäuse herausragt, ist insbesondere kein gesondertes Zubehör wie ein Schraubendreher für diese Betätigung erforderlich, stattdessen kann die gesamte Betätigung durch das Betätigungselement erfolgen, das Teil der Leiteranschlussklemme ist und somit daran befestigt ist.The clamping limb is thus located on the side facing away from the connecting limb, viewed in the conductor insertion direction. In this way, a conductor connection terminal with the possibility of rear conductor entry can be further developed in a production-related and user-friendly manner. A configuration of a conductor connection terminal in which the electrical conductor is inserted from the spring arc side of the clamping spring and extends straight through a part of the clamping spring is referred to as a rearward conductor insertion possibility. The present invention has the advantage that such a conductor terminal can be operated manually in a simple and convenient manner. If the actuating element protrudes from the housing in the non-actuated state, no separate accessory such as a screwdriver is required for this actuation, instead the entire actuation can be carried out by the actuating element, which is part of the conductor terminal and is therefore attached to it.

Da ein manueller Betätigungsbereich des Betätigungselementes von außen, d.h. an einer Position außerhalb des Gehäuses, manuell betätigbar ist, ist eine angenehme und bequeme Betätigung der Leiteranschlussklemme möglich. Der manuelle Betätigungsbereich kann z.B. als Betätigungsdrücker, der aus dem Gehäuse ragt, ausgebildet sein. Der manuelle Betätigungsbereich ist mechanisch direkt oder indirekt mit dem Betätigungsstößel gekoppelt. Das Betätigungselement erstreckt sich mit seinem Betätigungsstößel dann durch die Aussparung im Verbindungsschenkel hindurch, z.B. vom manuellen Betätigungsbereich in Richtung zum Klemmschenkel, und kann daher bei entsprechender manueller Betätigung den Klemmschenkel mechanisch beaufschlagen und dementsprechend auslenken. Der Betätigungsstößel kann im Wesentlichen bis zum Klemmschenkel hin ragen und je nach Ausführungsform auch im unbetätigten Zustand des Betätigungselementes daran anliegen oder zumindest kurz davor enden. Durch die Betätigung des Klemmschenkels kann die Klemmstelle geöffnet werden, sodass ein elektrischer Leiter von der Klemmstelle entfernt werden kann oder auf einfache Weise eingeführt werden kann. Die Klemmfeder und insbesondere der Klemmschenkel kann dabei als mechanisches Rückstellelement des Betätigungselementes fungieren, sodass keine gesonderte Rückstellfeder erforderlich ist.Since a manual operating area of the operating element can be operated manually from the outside, ie at a position outside the housing, the conductor connection terminal can be operated comfortably and conveniently. The manual actuation area can be designed, for example, as an actuation button that protrudes from the housing. The manual actuation area is mechanically coupled directly or indirectly to the actuation plunger. The actuating element then extends with its actuating plunger through the recess in the connecting leg, for example from the manual actuating area in the direction of the clamping leg, and can therefore mechanically act on the clamping leg with corresponding manual actuation and deflect it accordingly. The actuating plunger can essentially protrude as far as the clamping leg and, depending on the embodiment, also rest against it in the non-actuated state of the actuating element, or at least end just before it. The terminal point can be opened by actuating the terminal leg, so that an electrical conductor can be removed from the terminal point can or can be easily introduced. The clamping spring and in particular the clamping leg can act as a mechanical restoring element of the actuating element, so that no separate restoring spring is required.

Die Klemmfeder kann unterschiedlich ausgestaltet sein. Sie kann bspw. im Wesentlichen schlaufenförmig ausgebildet sein. Der Verbindungsschenkel kann von dem Anlageschenkel in einem schrägen Winkel oder nahezu im rechten Winkel fortgebogen sein. Der Klemmschenkel kann sich dabei wiederum zurück in Richtung zum Anlageschenkel erstrecken. Der Klemmschenkel kann am freien Ende eine Klemmkante aufweisen, die, zumindest wenn kein elektrischer Leiter in die Klemmstelle eingeführt ist, nahe des Anlageschenkels angeordnet sein kann. Die Klemmstelle kann zumindest teilweise durch die Klemmkante des Klemmschenkels gebildet sein.The clamping spring can be designed in different ways. It can, for example, be designed essentially in the form of a loop. The connection leg can be bent away from the abutment leg at an oblique angle or almost at a right angle. The clamping leg can in turn extend back in the direction of the contact leg. At the free end, the clamping leg can have a clamping edge which, at least when no electrical conductor is inserted into the clamping point, can be arranged close to the contact leg. The clamping point can be formed at least partially by the clamping edge of the clamping leg.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass der Leiter-Durchgangsöffnungsbereich und der Betätigungsstößel-Durchgangsöffnungsbereich eine gemeinsame Öffnung im Verbindungsschenkel ausbilden, z.B. eine Öffnung, die vollständig vom Material des Verbindungsschenkels umgeben ist. Auf diese Weise kann ein und dieselbe Aussparung im Verbindungsschenkel für das Durchführen des elektrischen Leiters und des Betätigungsstößels genutzt werden. Eine unnötige Schwächung des Verbindungsschenkels kann damit vermieden werden. Ein weiterer Vorteil ist, dass nur eine Aussparung für die Erfüllung dieser Funktionen hergestellt werden muss.According to an advantageous development of the invention, it is provided that the conductor through-opening area and the actuating plunger through-opening area form a common opening in the connecting leg, e.g. an opening that is completely surrounded by the material of the connecting leg. In this way, one and the same cutout in the connecting leg can be used for leading through the electrical conductor and the actuating plunger. An unnecessary weakening of the connecting leg can thus be avoided. Another advantage is that only one recess has to be made to fulfill these functions.

Alternativ kann außer der Leiter-Durchgangsöffnungsbereich eine gesonderte Aussparung für das Hindurchführen des Betätigungsstößels im Verbindungsschenkel vorhanden sein, z.B. derart, dass die Aussparung für das Hindurchführen des Betätigungsstößels durch einen Quersteg von dem Leiter-Durchgangsöffnungsbereich getrennt ist.Alternatively, in addition to the conductor through-opening area, there can be a separate recess for the passage of the actuating plunger in the connecting leg, e.g. such that the recess for the passage of the actuating plunger is separated from the conductor through-opening region by a crossbar.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Leiteranschlussklemme wenigstens einen Kontakteinsatz aufweist, der z.B. separate, zur Kontaktierung eines elektrischen Leiters eingerichtete Kontaktelemente aufweist, die zumindest die Klemmfeder und eine Stromschiene umfassen, wobei zwischen dem Klemmschenkel und der Stromschiene die Klemmstelle zum Festklemmen des elektrischen Leiters gebildet ist. Dies erlaubt eine zuverlässige elektrische Kontaktierung des elektrischen Leiters und eine widerstandsarme Stromführung. Je nach Ausführungsform kann sich die Stromschiene durch den Leiter-Durchgangsöffnungsbereich hindurcherstrecken oder bereits davor enden. Die Klemmfeder kann mit ihrem Anlageschenkel an der Stromschiene oder an einem anderen Bauteil der Leiteranschlussklemme befestigt sein. Beispielsweise kann der Anlageschenkel auf der dem Klemmschenkel abgewandten Seite der Stromschiene angeordnet sein, sodass die Stromschiene sich zumindest mit einem Teilbereich zwischen dem Anlageschenkel und dem Klemmschenkel hindurcherstreckt.According to an advantageous further development of the invention, it is provided that the conductor connection terminal has at least one contact insert which, for example, has contact elements set up for contacting an electrical conductor, which comprise at least the clamping spring and a busbar, the clamping point for clamping the electrical conductor being formed between the clamping leg and the busbar. This allows reliable electrical contacting of the electrical conductor and low-resistance current conduction. Depending on the embodiment, the busbar can extend through the conductor through-opening area or end in front of it. The clamping spring can be fastened with its contact leg to the conductor rail or to another component of the conductor connection terminal. For example, the contact leg can be arranged on the side of the busbar facing away from the clamping leg, so that the busbar extends through at least a partial area between the contact leg and the clamping leg.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement einen Führungsabschnitt zur definierten mechanischen Führung des Betätigungselements aufweist, der zumindest zum Teil vom Verbindungsschenkel aus gesehen hinter dem Federbogen angeordnet ist. Mit anderen Worten, der Führungsabschnitt befindet sich zumindest zum Teil oberhalb des Federbogens, wenn der Anlageschenkel unten angeordnet ist. Der Führungsabschnitt des Betätigungselementes ermöglicht es, das Betätigungselement in definierter Weise mechanisch zu führen, z.B. in einem Führungskanal des Gehäuses. Ist das Betätigungselement als linear bewegliches Betätigungselement, z.B. als Betätigungsdrücker ausgebildet, so kann durch den Führungsabschnitt und den im Gehäuse zur Aufnahme des Führungsabschnittes vorgesehenen Führungskanal eine Linearführung für das Betätigungselement gebildet sein. Durch diese mechanische Führung des Betätigungselementes wird ein Verkanten bei der manuellen Betätigung vermieden, sodass die manuelle Betätigung einfacher und störungsfrei durchgeführt werden kann. Das innere Ende des Führungskanals im Gehäuse bildet zudem einen Tiefenanschlag für den in dem Führungskanal aufgenommenen Führungsabschnitt des Betätigungselements. Auf diese Wiese wird vorteilhaft ein Schutz gegen ein übermäßiges Aufschwenken bzw. Überdrücken des Klemmschenkels der Klemmfeder gewährleistet.According to an advantageous development of the invention, it is provided that the actuating element has a guide section for defined mechanical guidance of the actuating element, which is arranged at least partially behind the spring bow as seen from the connecting leg. In other words, the guide section is located at least partially above the spring bow when the contact leg is arranged at the bottom. The guide section of the actuating element makes it possible to mechanically guide the actuating element in a defined manner, for example in a guide channel of the housing. If the actuating element is designed as a linearly movable actuating element, eg as an actuating push button, a linear guide for the actuating element can be formed by the guide section and the guide channel provided in the housing for receiving the guide section. This mechanical guidance of the actuating element prevents tilting during manual actuation, so that manual actuation can be carried out more easily and without problems. The inner end of the guide channel in the housing also forms a depth stop for the guide section of the actuating element accommodated in the guide channel. In this way, protection against excessive swinging open or overpressing of the clamping leg of the clamping spring is advantageously ensured.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass sich zumindest ein Teilbereich des Führungsabschnittes in eine schlitzförmige Aussparung der Klemmfeder, insbesondere eine im Bereich des Federbogens angeordnete schlitzförmige Aussparung, hineinerstreckt. Der in die schlitzförmige Aussparung der Klemmfeder sich hineinerstreckende Teilbereich des Führungsabschnittes kann bspw. als sich vertikal nach unten hin, d.h. in Richtung Anlageschenkel hin, erstreckender Längssteg ausgebildet sein, sodass der Führungsabschnitt zusammen mit dem Längssteg im Querschnitt eine T-Form aufweist. Hierdurch wird die Führung des Betätigungselementes weiter verbessert, da auch die Klemmfeder hierzu zusätzlich beiträgt. Zudem kann die mechanische Stabilität des Betätigungselementes, insbesondere im Führungsabschnitt, mit wenig Aufwand erhöht werden. Hierdurch wird eine Versteifung des Betätigungselementes bewirkt, durch die das Betätigungselement im oberen Bereich, d.h. im Bereich des Federbogens, flach gehalten werden kann. Dies hat wiederum den Vorteil, dass bei der Realisierung der Leiteranschlussklemme Bauraum gespart werden kann und das Gehäuse klein gehalten werden kann.According to an advantageous development of the invention, it is provided that at least a partial area of the guide section extends into a slit-shaped recess of the clamping spring, in particular a slit-shaped recess arranged in the area of the spring bow. The portion of the guide section that extends into the slot-shaped recess of the clamping spring can be designed, for example, as a longitudinal web that extends vertically downwards, i.e. in the direction of the contact leg, so that the guide section together with the longitudinal web has a T-shape in cross section. This further improves the guidance of the actuating element, since the clamping spring also contributes to this. In addition, the mechanical stability of the actuating element, particularly in the guide section, can be increased with little effort. This results in a stiffening of the actuating element, as a result of which the actuating element can be kept flat in the upper area, i.e. in the area of the spring bow. This in turn has the advantage that space can be saved when realizing the conductor connection terminal and the housing can be kept small.

Gemäß einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass das Betätigungselement einen Basisabschnitt aufweist, von dem insbesondere U-förmig und beabstandet voneinander der Betätigungsstößel und der Führungsabschnitt in Richtung zur Klemmfeder hin abragen. Dies erlaubt eine einfache Herstellung des Betätigungselementes, z.B. einstückig aus einem Material, z.B. aus einem Isolierstoffmaterial. Der manuelle Betätigungsbereich des Betätigungselementes ist mechanisch im Wesentlichen starr mit dem Betätigungsstößel gekoppelt, z.B. über den Basisabschnitt des Betätigungselementes.According to an advantageous development of the invention, it is provided that the actuating element has a base section from which the actuating plunger and the guide section protrude in the direction of the clamping spring, in particular in a U-shape and at a distance from one another. This allows a simple production of the actuating element, for example in one piece from one material, for example from an insulating material. The manual actuation portion of the actuator is mechanically substantially rigidly coupled to the actuator plunger, eg, via the base portion of the actuator.

Gemäß der Erfindung ist vorgesehen, dass das Gehäuse aus wenigstens zwei separaten Teilen gebildet ist, die miteinander zur Bildung des Gehäuses verbindbar sind, wobei zumindest ein Teil des Gehäuses einen Leiterführungsfortsatz aufweist, der sich durch den Leiter-Durchgangsöffnungsbereich hindurcherstreckt. Auf diese Weise kann die Leiteranschlussklemme in fertigungstechnischer Sicht und im Hinblick auf die Anwendungsfreundlichkeit weiter verbessert werden. Ein Fehleinstecken des elektrischen Leiters oder ein unerwünschtes Ausfasern einzelner Litzen eines litzenförmigen Leiters kann wirkungsvoll vermieden werden. Zudem ist die Montage der Leiteranschlussklemme weiterhin einfach möglich, da der Leiterführungsfortsatz nicht als separates Element montiert werden muss, sondern bereits Bestandteil des Gehäuses ist, sodass beim Zusammensetzen der Teile des Gehäuses automatisch der Leiterführungsfortsatz an der richtigen Stelle angeordnet wird.According to the invention it is provided that the housing is formed from at least two separate parts which can be connected to one another to form the housing, wherein at least one part of the housing has a conductor guide extension which extends through the conductor passage opening region. In this way, the conductor connection terminal can be further improved in terms of production technology and in terms of user-friendliness. Incorrect insertion of the electrical conductor or undesired unraveling of individual strands of a stranded conductor can be effectively avoided. In addition, the assembly of the conductor terminal is still easy, since the conductor routing extension does not have to be installed as a separate element, but is already part of the housing, so that when the parts of the housing are assembled, the conductor routing extension is automatically arranged in the correct place.

Gemäß einer Ausführungsform, die nicht unter den Anspruchsgegenstand fällt, ist vorgesehen, dass der Leiterführungsfortsatz axial fluchtend zum Leiter-Durchgangsöffnungsbereich angeordnet ist. Hierdurch wird das anwendungsfreundliche Einstecken eines elektrischen Leiters weiter gefördert.According to one embodiment, which does not fall under the subject matter of the claim, it is provided that the conductor guide extension is arranged in axial alignment with the conductor through-opening area. This further promotes the user-friendly insertion of an electrical conductor.

Gemäß einer Ausführungsform, die nicht unter den Anspruchsgegenstand fällt, ist ein Kontakteinsatz einer Leiteranschlussklemme vorgesehen, insbesondere einer Leiteranschlussklemme der zuvor erläuterten Art, wobei der Kontakteinsatz zumindest eine Stromschiene und eine Klemmfeder aufweist, wobei die Klemmfeder einen Anlageschenkel aufweist, der mit der Stromschiene mechanisch gekoppelt ist, wobei die Stromschiene wenigstens eine Kontaktzunge und wenigstens eine Befestigungszunge aufweist, zwischen denen der Anlageschenkel festgeklemmt ist. Dies hat den Vorteil, dass ein selbsttragender und Schüttgut-tauglicher Kontakteinsatz bereitgestellt werden kann. Die Teile des Kontakteinsatzes können auf einfache Weise miteinander verbunden werden, nämlich durch die Klemmbefestigung des Anlageschenkels an der Stromschiene. Die Befestigungszunge kann gegenüber der Kontaktzunge über einen mit zwei Biegeabschnitten, die in entgegengesetztem Biegesinn gebogen sind, gebildeten Bereich derart beabstandet sein, dass ein Teil der Befestigungszunge im Wesentlichen parallel zur Kontaktzunge verläuft und einen Befestigungsfreiraum zwischen Kontaktzunge und Befestigungszunge bildet, in die der Anlageschenkel einsteckbar ist.According to an embodiment that does not fall under the subject matter of the claim, a contact insert of a conductor terminal is provided, in particular a conductor terminal of the type explained above, wherein the contact insert has at least one busbar and a clamping spring, the clamping spring having a contact leg with the busbar is mechanically coupled, wherein the busbar has at least one contact tongue and at least one fastening tongue, between which the contact leg is clamped. This has the advantage that a self-supporting contact insert suitable for bulk goods can be provided. The parts of the contact insert can be connected to one another in a simple manner, namely by clamping the contact leg to the busbar. The fastening tongue can be spaced apart from the contact tongue over an area formed with two bending sections, which are bent in opposite bending directions, in such a way that a part of the fastening tongue runs essentially parallel to the contact tongue and forms a fastening space between the contact tongue and the fastening tongue, into which the contact leg can be inserted is.

Gemäß einer Ausführungsform, die nicht unter den Anspruchsgegenstand fällt, ist vorgesehen, dass die Stromschiene entlang einer Leitereinsteckrichtung L links und rechts seitlich von der Kontaktzunge jeweils eine Befestigungszunge aufweist und der Anlageschenkel eine endseitig abragende Haltezunge aufweist, die sich zwischen den Befestigungszungen der Stromschiene hindurcherstreckt. Auf diese Weise wird die Fixierung der Klemmfeder an der Stromschiene weiter verbessert. Die Fixierung des Anlageschenkels an der Stromschiene kann durch die zwei Befestigungszungen symmetrisch erfolgen. Auch die Montage wird vereinfacht, da der Anlageschenkel mit seiner abragenden Haltezunge einfach zwischen die Befestigungszungen eingesteckt werden kann.According to one embodiment, which does not fall under the subject matter of the claim, it is provided that the busbar has a fastening tongue to the left and right of the contact tongue along a conductor insertion direction L, and the contact leg has a retaining tongue that protrudes at the end and extends between the fastening tongues of the busbar. In this way, the fixation of the clamping spring on the conductor rail is further improved. The attachment leg can be fixed symmetrically to the busbar by the two attachment tongues. Assembly is also simplified since the contact leg with its protruding holding tongue can simply be inserted between the fastening tongues.

Gemäß einer Ausführungsform, die nicht unter den Anspruchsgegenstand fällt, ist vorgesehen, dass die Klemmfeder eine Zusatzaussparung im Anlageschenkel aufweist, durch die der Klemmschenkel oder zumindest eine Klemmkante des Klemmschenkels hindurchführbar ist. Dies hat den Vorteil, dass die Herstellung der Klemmfeder mit der notwendigen Vorspannung in der Ausgangslage vereinfacht wird. Bei der Herstellung kann der Klemmschenkel bis durch die Zusatzaussparung im Anlageschenkel überbogen werden, sodass er nach dem Rückfedern seine in der Ausgangslage vorhandene Vorspannung erhält.According to an embodiment that does not fall under the subject matter of the claim, it is provided that the clamping spring has an additional recess in the contact leg, through which the clamping leg or at least one clamping edge of the clamping leg can be passed. This has the advantage that it simplifies the production of the clamping spring with the necessary prestressing in the starting position. During production, the clamping limb can be bent over through the additional cutout in the contact limb, so that after springing back it receives its pretension that is present in the starting position.

Gemäß einer Ausführungsform, die nicht unter den Anspruchsgegenstand fällt, ist vorgesehen, dass der Klemmschenkel im Übergangsbereich zum Federbogen einen Verjüngungsbereich aufweist, in dem die Materialbreite des Klemmschenkels geringer ist als in vom Federbogen entfernteren Bereichen des Klemmschenkels. Auf diese Weise kann dieAccording to one embodiment, which does not fall under the subject matter of the claim, it is provided that the clamping leg has a tapering area in the transition area to the spring bow has, in which the material width of the clamping leg is smaller than in areas of the clamping leg that are further away from the spring arc. In this way, the

Federkonstante der Klemmfeder im Bereich des Klemmschenkels zumindest im Wesentlichen an die Federkonstante der Klemmfeder im Bereich des Verbindungsschenkels, wo der Leiter-Durchgangsöffnungsbereich vorhanden ist, angepasst werden. Der Klemmschenkel kann insbesondere im Bereich seiner Klemmkante eine größere Breite haben als im Verjüngungsbereich. Auf diese Weise wird eine relativ breite Klemmkante bereitgestellt, die das Festklemmen eines elektrischen Leiters vereinfacht.The spring constant of the clamping spring in the area of the clamping leg can be adapted at least essentially to the spring constant of the clamping spring in the area of the connecting leg where the conductor through-opening area is present. In particular, the clamping leg can have a greater width in the area of its clamping edge than in the narrowing area. In this way, a relatively wide clamping edge is provided, which simplifies the clamping of an electrical conductor.

Gemäß einer Ausführungsform, die nicht unter den Anspruchsgegenstand fällt, ist vorgesehen, dass der Klemmschenkel auch außerhalb des Verjüngungsbereiches eine geringere Materialbreite aufweist als die Klemmfeder im Bereich des Federbogens hat. Auf diese Weise ist der Federbogen im Vergleich zu anderen Bereichen der Klemmfeder relativ breit und damit biegesteif ausgebildet und verformt sich bei einer Auslenkung des Klemmschenkels nur wenig.According to one embodiment, which does not fall under the subject matter of the claim, it is provided that the clamping leg also has a smaller material width outside of the narrowing area than the clamping spring has in the area of the spring bow. In this way, the spring bow is relatively wide in comparison to other areas of the clamping spring and is therefore designed to be rigid and deforms only slightly when the clamping leg is deflected.

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°). Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen unter Verwendung von Zeichnungen näher erläutert.For the purposes of the present invention, the indefinite term "a" is not to be understood as a numeral. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component". If angles are specified in degrees, these refer to a circular measurement of 360 degrees (360°). The invention is explained in more detail below on the basis of exemplary embodiments using drawings.

Der in Figur 1 links dargestellte Kontakteinsatz weist eine Stromschiene 3 und eine Klemmfeder 4 auf. Die Stromschiene 3 ist aus einem elektrisch gut leitfähigen Material ausgebildet. Die Klemmfeder 4 ist ebenfalls aus elektrisch leitendem Material ausgebildet, weist aber zusätzlich besondere Federeigenschaften im Sinne eines Federstahls auf.the inside figure 1 The contact insert shown on the left has a busbar 3 and a clamping spring 4 . The conductor rail 3 is made of a material with good electrical conductivity. The clamping spring 4 is also made of electrically conductive material formed, but also has special spring properties in the sense of a spring steel.

Die Stromschiene 3 weist einen Basisbereich 30 auf, von dem eine Kontaktzunge 31 und jeweils seitlich links und rechts davon zwei gebogene Befestigungszungen 33 abragen. Die Kontaktzunge 31 weist einen nach oben gebogenen erhabenen Bereich 32 auf, der zusammen mit einer Klemmkante 44 der Klemmfeder 4 eine Klemmstelle für einen elektrischen Leiter bildet. Die Kontaktzunge 31 erstreckt sich noch etwas über den erhabenen Bereich 32 hinaus.The conductor rail 3 has a base region 30 from which a contact tongue 31 and two curved fastening tongues 33 protrude laterally to the left and right of it. The contact tongue 31 has an upwardly bent raised area 32 which, together with a clamping edge 44 of the clamping spring 4, forms a clamping point for an electrical conductor. The contact tongue 31 still extends somewhat beyond the raised area 32 .

Die Klemmfeder 4, die in der Figur 1 zusätzlich rechts etwas verkleinert als Einzelbauteil dargestellt ist, weist einen Anlageschenkel 40, einen Verbindungsschenkel 41, einen Federbogen 42 und einen Klemmschenkel 43 auf, die in der zuvor genannten Reihenfolge hintereinander entlang der Klemmfeder 4 angeordnet sind. Der Klemmschenkel 43 hat am freien Ende eine Klemmkante 44. Ausgehend von dem Anlageschenkel 40 ist der Verbindungsschenkel 41 nach oben abgebogen, z.B. schräg nach oben. Der über den Federbogen 42 mit dem Verbindungsschenkel 41 verbundene Klemmschenkel 43 kann ungefähr parallel zum Verbindungsschenkel 41 verlaufen, zumindest wenn kein elektrischer Leiter angeklemmt ist.The clamping spring 4 in the figure 1 is also shown on the right somewhat reduced as an individual component, has a contact leg 40, a connecting leg 41, a spring bow 42 and a clamping leg 43, which are arranged one behind the other along the clamping spring 4 in the aforementioned order. The clamping leg 43 has a clamping edge 44 at the free end. Starting from the contact leg 40, the connecting leg 41 is bent upwards, eg obliquely upwards. The clamping leg 43 connected to the connecting leg 41 via the spring bow 42 can run approximately parallel to the connecting leg 41, at least when no electrical conductor is clamped.

Der Verbindungsschenkel 41 weist eine innere fensterartige Aussparung auf, die als gemeinsame Öffnung 46 ausgebildet ist, die einen Leiter-Durchgangsöffnungsbereich 46a und einen Betätigungsstößel-Durchgangsöffnungsbereich 46b aufweist. Durch den Leiter-Durchgangsöffnungsbereich 46 kann ein elektrischer Leiter in Leitereinsteckrichtung L sozusagen rückwärtig durch den Verbindungsschenkel 41 zur Klemmstelle zwischen der Klemmkante 44 und dem erhabenen Bereich 32 eingeführt werden. Wie erkennbar ist, ist die gemeinsame Öffnung 46 relativ langerstreckend ausgebildet, z.B. im Wesentlichen über die gesamte Länge des Verbindungsschenkels 41. Eine solche Längserstreckung wird für die Durchführung eines elektrischen Leiters eigentlich nicht benötigt. Wie nachfolgend noch erläutert wird, wird ein Teil der gemeinsamen Öffnung 46, nämlich der Betätigungsstößel-Durchgangsöffnungsbereich 46b, zugleich als Durchführungsöffnung für einen Teil eines Betätigungselements 5 genutzt.The connecting leg 41 has an inner window-like recess formed as a common opening 46 having a conductor through-hole portion 46a and an operating plunger through-hole portion 46b. Through the conductor passage opening area 46, an electrical conductor can be inserted backwards in the conductor insertion direction L, so to speak, through the connecting leg 41 to the clamping point between the clamping edge 44 and the raised area 32. As can be seen, the common opening 46 has a relatively long extension, for example essentially over the entire length of the connecting leg 41. Such a longitudinal extension is actually not required for the passage of an electrical conductor. As will be explained later, a part of the common opening 46, namely the actuating rod through opening area 46b, at the same time used as a feed-through opening for part of an actuating element 5.

Die Klemmfeder 4 weist im Bereich des Anlageschenkels 40 eine Zusatzaussparung 47 auf. Diese Zusatzaussparung 47 dient dem Herstellprozess der Klemmfeder 4 in einer Biegevorrichtung. Durch die Zusatzaussparung 47 wird es möglich, die notwendige Vorspannung der Klemmfeder 4 in der in Figur 1 links dargestellten Position, wenn kein elektrischer Leiter eingeführt ist, zu erzeugen. Der Klemmschenkel 43 wird bei diesem Biegevorgang bis durch die Zusatzaussparung 47 überbogen, damit er seine in der gewünschten späteren Ausgangslage notwendige Vorspannung erhält.The clamping spring 4 has an additional recess 47 in the area of the contact leg 40 . This additional recess 47 is used in the manufacturing process of the clamping spring 4 in a bending device. The additional recess 47 makes it possible to apply the necessary pretensioning of the clamping spring 4 in the figure 1 position shown on the left when no electrical conductor is inserted. During this bending process, the clamping leg 43 is bent over through the additional recess 47 so that it receives the prestressing required in the later desired initial position.

Erkennbar ist ferner ein hinsichtlich der Materialbreite der Klemmfeder 4 schmaler als die übrigen Bereiche des Anlageschenkels 40 ausgebildeter Bereich des Anlageschenkels 40, der eine Haltezunge 48 bildet. Wird die Klemmfeder 4 mit der Stromschiene 3 in der in Figur 1 links dargestellten Weise zusammengesteckt, so liegt die Kontaktzunge 31 mit ihrer Unterseite auf der Oberseite des Anlageschenkels 40 auf. Die Haltezunge 48 erstreckt sich dabei zwischen den Befestigungszungen 33 hindurch. In dieser Position liegen die Befestigungszungen 33 zudem auf der der Kontaktzunge abgewandten Unterseite des Anlageschenkels 40 an, und zwar in dem gegenüber der Haltezunge 48 verbreiterten Bereich des Anlageschenkels 40. Wie beispielsweise in der Figur 2 auch erkennbar ist, verlaufen die freien Endbereiche der Befestigungszungen 33 nach dem abgekröpften S-förmigen Biegebereich in etwa parallel zur Steckzunge 31.A region of the contact leg 40 which is narrower in terms of the material width of the clamping spring 4 than the other areas of the contact leg 40 and which forms a retaining tongue 48 can also be seen. If the clamping spring 4 with the busbar 3 in the in figure 1 Put together in the manner shown on the left, the contact tongue 31 rests with its underside on the upper side of the contact leg 40 . The retaining tongue 48 extends between the fastening tongues 33 therethrough. In this position, the fastening tongues 33 also rest on the underside of the contact leg 40 facing away from the contact tongue, specifically in the area of the contact leg 40 that is widened in relation to the retaining tongue 48. As, for example, in FIG figure 2 As can also be seen, the free end areas of the fastening tongues 33 run approximately parallel to the plug-in tongue 31 after the offset S-shaped bending area.

Erkennbar ist ferner, dass die Klemmfeder 4 im Übergangsbereich von dem Federbogen 42 zum Klemmschenkel 43 einen Verjüngungsabschnitt 45 aufweist, der als Abschnitt mit verringerter Materialbreite im Vergleich zur Materialbreite der übrigen Teile des Klemmschenkels 43 ausgebildet ist.It can also be seen that the clamping spring 4 has a tapered section 45 in the transition area from the spring arc 42 to the clamping leg 43 , which is designed as a section with a reduced material width compared to the material width of the remaining parts of the clamping leg 43 .

Damit der Kontakteinsatz zum Entfernen oder Einführen eines elektrischen Leiters in die Klemmstelle geöffnet werden kann, d.h. der Klemmschenkel 43 mit seiner Klemmkante 44 von dem erhabenen Bereich 32 fortgebogen werden kann, ist ein Betätigungselement 5 vorhanden, das in der Figur 2 erkennbar ist. Das Betätigungselement 5 kann bspw. in Form eines linear verschieblichen Drückers ausgebildet sein. Das Betätigungselement 5 kann auch anders ausgebildet sein, z.B. als verschwenkbares Betätigungselement, z.B. als Betätigungshebel. In den nachfolgenden Ausführungsbeispielen wird von einem Betätigungselement 5 in Form eines linear verschieblichen Drückers ausgegangen.So that the contact insert for removing or inserting an electrical conductor can be opened in the terminal point, ie the terminal leg 43 with its Clamping edge 44 can be bent away from the raised area 32, an actuating element 5 is present, which is in the figure 2 is recognizable. The actuating element 5 can be designed, for example, in the form of a linearly displaceable pusher. The actuating element 5 can also be designed differently, for example as a pivotable actuating element, for example as an actuating lever. In the following exemplary embodiments, an actuating element 5 in the form of a linearly displaceable pusher is assumed.

Das Betätigungselement 5 weist einen Basisabschnitt 50 auf, von dem in Seitenansicht ungefähr U-förmig im unteren Bereich ein Betätigungsstößel 51 und im oberen Bereich ein Führungsabschnitt 52 abragen. Von dem Basisabschnitt 50 ragt ferner nach rechts hin ein manueller Betätigungsbereich 53 ab. Wie in der Figur 2 erkennbar ist, ragt der Betätigungsstößel 51 durch den oberen Bereich der Betätigungsstö-ßel-Durchgangsöffnungsbereich 46 hindurch bis zum Klemmschenkel 43. Alternativ wäre es auch möglich, den Leiter-Durchgangsöffnungsbereich 46 nur im unteren Bereich, wo ein elektrischer Leiter zur Klemmstelle geführt werden soll, vorzusehen und eine gesonderte obere Aussparung vorzusehen, die als Durchführungsöffnung für den Betätigungsstößel 51 dient.The actuating element 5 has a base section 50 from which, in a side view, an approximately U-shaped protrudes in the lower area and an actuating plunger 51 and in the upper area a guide section 52 . Furthermore, a manual actuation area 53 protrudes from the base section 50 to the right. Like in the figure 2 As can be seen, the actuating plunger 51 protrudes through the upper area of the actuating plunger through-opening area 46 to the clamping leg 43. Alternatively, it would also be possible to have the conductor through-opening area 46 only in the lower area, where an electrical conductor is to be routed to the clamping point. to be provided and to provide a separate upper recess, which serves as a passage opening for the actuating plunger 51.

Die Figur 3 zeigt eine Leiteranschlussklemme 1 mit einem Gehäuse 2. Im Gehäuse 2, oder zumindest weitgehend im Gehäuse 2, sind die zuvor anhand der Figur 2 erläuterten Elemente angeordnet, nämlich der Kontakteinsatz mit der Stromschiene 3 und der Klemmfeder 4, sowie das Betätigungselement 5. Das Gehäuse 2 weist eine Leitereinführungsöffnung 20 auf, durch die ein elektrischer Leiter in das Gehäuse 2 eingeführt werden kann und zur Klemmstelle geführt werden kann. Das Gehäuse 2 weist außerdem eine Betätigungselementdurchführungsöffnung 21 auf, durch die der manuelle Betätigungsbereich 53 hindurchragt und in dem in Figur 3 dargestellten unbetätigten Zustand des Betätigungselementes 5 aus dem Gehäuse 2 herausragt. In diesem Zustand liegt die Klemmkante 44 der Klemmfeder 4 an dem erhabenen Bereich 32 der Stromschiene 3 an. In diesem Zustand ist somit die Klemmstelle geschlossen. Soll die Klemmstelle geöffnet werden, so ist manuell eine Betätigungskraft auf den manuellen Betätigungsbereich 53 auszuüben, sodass das gesamte Betätigungselement 5 nach links hin verschoben wird, wie die Figur 4 zeigt. Durch dieses Verschieben des Betätigungselementes 5 nach links wird der Klemmschenkel 43 durch den Betätigungsstößel 51 ausgelenkt und von dem erhabenen Bereich 32 entfernt. Es kann nun durch die Leitereinführungsöffnung 20 ein elektrischer Leiter 10 eingeführt werden, sodass dieser zumindest mit seinem abisolierten Bereich 11 sich bis zur Kontaktzunge 31 erstreckt und durch die Klemmkante 44 der Klemmfeder gegen die Stromschiene, insbesondere gegen den erhabenen Bereich 32, gedrückt werden kann, wenn das Betätigungselement 5 nicht mehr betätigt wird.The figure 3 shows a conductor terminal 1 with a housing 2. In the housing 2, or at least largely in the housing 2, the previously based on figure 2 explained elements are arranged, namely the contact insert with the busbar 3 and the clamping spring 4, and the actuating element 5. The housing 2 has a conductor insertion opening 20 through which an electrical conductor can be inserted into the housing 2 and can be guided to the terminal point. The housing 2 also has an actuating element passage opening 21 through which the manual actuating portion 53 protrudes and in which figure 3 illustrated unactuated state of the actuating element 5 protrudes from the housing 2. In this state, the clamping edge 44 of the clamping spring 4 rests against the raised area 32 of the busbar 3 . In this state, the clamping point is closed. If the clamping point is to be opened, an actuating force must be exerted manually on the manual actuating area 53 so that the entire actuating element 5 is shifted to the left, like the figure 4 shows. As a result of this displacement of the actuating element 5 to the left, the clamping leg 43 is deflected by the actuating plunger 51 and removed from the raised area 32 . An electrical conductor 10 can now be inserted through the conductor insertion opening 20 so that it extends at least with its stripped area 11 to the contact tongue 31 and can be pressed against the busbar, in particular against the raised area 32, by the clamping edge 44 of the clamping spring. when the actuating element 5 is no longer actuated.

Im Gehäuse 2 ist ferner ein Führungskanal 22 vorhanden, in dem der Führungsabschnitt 52 des Betätigungselementes 5 geführt ist. Auf diese Weise ist das Betätigungselement 5 im Gehäuse 2 sicher gelagert und kann mit geringem Kraftaufwand und ohne Verkanten betätigt werden.In the housing 2 there is also a guide channel 22 in which the guide section 52 of the actuating element 5 is guided. In this way, the actuating element 5 is securely mounted in the housing 2 and can be actuated with little effort and without tilting.

Gemäß der Erfindung ist das Gehäuse mehrteilig ausgebildet. Im dargestellten Ausführungsbeispiel ist das Gehäuse 2 zweiteilig ausgebildet, und zwar mit einem Hauptgehäuseteil 23 und einem Verschlussteil 24. Das Verschlussteil 24 weist Rastelemente 25 auf, mit denen das Verschlussteil im Sinne einer Rastbefestigung am Hauptgehäuseteil 23 fixiert werden kann. Erkennbar ist ferner, dass das Betätigungselement 5 mit seiner in der Ansicht erkennbaren Unterseite zumindest abschnittsweise auf dem Verschlussteil 24 aufliegt und an diesem zusätzlich geführt wirdAccording to the invention, the housing is designed in several parts. In the exemplary embodiment shown, the housing 2 is designed in two parts, namely with a main housing part 23 and a closure part 24. The closure part 24 has latching elements 25 with which the closure part can be fixed to the main housing part 23 in the sense of a latching attachment. It can also be seen that the actuating element 5 rests with its underside, which can be seen in the view, at least in sections on the closure part 24 and is additionally guided on it

Die Figur 5 zeigt eine Ausführungsform des Kontakteinsatzes, bestehend aus einer Stromschiene 3 und einer Klemmfeder 4, der sich von dem zuvor erläuterten Kontakteinsatz dadurch unterscheidet, dass die Klemmfeder 4 eine schlitzförmige Aussparung 49 im Bereich des Federbogens 42 aufweist. Der Federbogen 42 ist durch die schlitzförmige Aussparung 49 in zwei nebeneinander verlaufende Federbogenschenkel aufgeteilt.The figure 5 shows an embodiment of the contact insert, consisting of a busbar 3 and a clamping spring 4, which differs from the previously explained contact insert in that the clamping spring 4 has a slot-shaped recess 49 in the area of the spring arc 42. The spring bow 42 is divided by the slit-shaped recess 49 into two spring bow legs running next to one another.

Die Figur 6 zeigt eine vergleichbare Ansicht wie die Figur 2, wobei von dem Kontakteinsatz der Figur 5 ausgegangen wird. Das in der Figur 6 dargestellte Betätigungselement 5 unterscheidet sich von der zuvor erläuterten Ausführungsform dadurch, dass im Bereich zwischen dem Führungsabschnitt 52 und dem Betätigungsstößel 50, insbesondere überwiegend am Führungsabschnitt 52 innerhalb des U-förmigen Bereiches, ein Längssteg 54 vorhanden ist. Dieser Längssteg 54 dient der Versteifung des Betätigungselementes 5, sodass das Betätigungselement 5 nicht aufgedrückt werden kann. Durch diese Versteifung kann das Betätigungselement 5 zudem in dem Bereich oberhalb des Federbogens 42 relativ flach gehalten werden, sodass Bauraum eingespart werden kann. Wie erkennbar ist, kann der Längssteg 54 zumindest im betätigten Zustand des Betätigungselementes 5 in die schlitzförmige Aussparung 49 eintauchen und wird dort aufgenommen.The figure 6 shows a view similar to that figure 2 , where from the contact insert the figure 5 is assumed. That in the figure 6 Actuating element 5 shown differs from the previously explained embodiment characterized in that in the area between the guide section 52 and the actuating plunger 50, in particular predominantly on the guide section 52 within the U-shaped area, a longitudinal web 54 is present. This longitudinal web 54 serves to reinforce the actuating element 5 so that the actuating element 5 cannot be pressed open. As a result of this stiffening, the actuating element 5 can also be kept relatively flat in the area above the spring bow 42, so that installation space can be saved. As can be seen, the longitudinal web 54 can dip into the slot-shaped recess 49 at least in the actuated state of the actuating element 5 and is received there.

Die Figur 7 zeigt eine Leiteranschlussklemme 1 in einer mit der Figur 4 vergleichbaren Darstellung, wobei die anhand der Figur 6 zuvor erläuterten Elemente innerhalb des Gehäuses 2 angeordnet sind.The figure 7 shows a conductor terminal 1 in a with the figure 4 comparable representation, the basis of which figure 6 previously explained elements are arranged within the housing 2.

Die Figur 8 zeigt eine Leiteranschlussklemme, die im Wesentlichen der Figur 3 entspricht, wobei in einer perspektivischen Ansicht schräg auf die Leitereinführungsöffnung 20 geblickt wird. Wie erkennbar ist, weist das Verschlussteil 24 einen Leiterführungsfortsatz 26 auf, von dem in der Darstellung der Figur 8 nur die eine (rechte) Hälfte erkennbar ist. Der Leiterführungsfortsatz 26 ist hülsenförmig. Der Leiterführungsfortsatz 26 erstreckt sich durch die Leiter-Durchgangsöffnungsbereich 46 hindurch. Der Leiterführungsfortsatz 26 bildet eine Art Verlängerung der Leitereinführungsöffnung 20. Erkennbar ist in der Figur 8 ferner, dass das Betätigungselement 5, insbesondere der Betätigungsstößel 51 sowie der Basisabschnitt 50 an ihrer der Leitereinführungsöffnung 20 zugewandten Seite eine Wölbung aufweisen, welche einen Abschnitt der Leitereinführungsöffnung 20 bilden.The figure 8 shows a conductor terminal, which is essentially the figure 3 corresponds, wherein the conductor insertion opening 20 is viewed obliquely in a perspective view. As can be seen, the closure part 24 has a conductor guide extension 26, from which in the representation of figure 8 only one (right) half is recognizable. The conductor guide extension 26 is sleeve-shaped. The conductor guide extension 26 extends through the conductor through-opening area 46 . The conductor guide extension 26 forms a kind of extension of the conductor insertion opening 20. Can be seen in FIG figure 8 furthermore, that the actuating element 5, in particular the actuating plunger 51 and the base section 50, have a bulge on their side facing the conductor insertion opening 20, which forms a section of the conductor insertion opening 20.

Die Figur 9 zeigt das Verschlussteil 24 in Einzelteildarstellung. Erkennbar ist der einstückig am Verschlussteil 24 angeformte Leiterführungsfortsatz 26, der einen Leiterführungskanal bildet, der im Bereich 27 eine Verjüngung aufweisen kann.The figure 9 shows the closure part 24 in detail. The conductor guide extension 26 which is integrally formed on the closure part 24 and forms a conductor guide channel which can have a narrowing in the region 27 can be seen.
