Description

Die Erfindung betrifft einen Klemmkontakt zur elektrischen Anbindung von Leitern, mit einer Klemmstelle, die ein Kontaktfeld zur Anlage des elektrischen Leiters und einen Federschenkel umfasst, der bei geschlossenem Klemmkontakt den elektrischen Leiter zwischen sich und dem Kontaktfeld hält, wobei der elektrische Leiter in die Klemmstelle einschiebbar ist und der Federschenkel - gegebenenfalls unter Einschluss eines Winkels mit dem Kontaktfeld - in Einschubrichtung des Leiters orientiert ist.The invention relates to a terminal contact for the electrical connection of conductors, with a terminal point, which includes a contact pad for contacting the electrical conductor and a spring leg, which holds the electrical conductor between them and the contact pad with closed terminal contact, wherein the electrical conductor can be inserted into the terminal point is and the spring leg - optionally including an angle with the contact field - oriented in the insertion direction of the conductor.

Aus dem druckschriftlich nicht belegbaren Stand der Technik sind derartige Klemmkontakte hinlänglich bekannt und haben in der elektrischen Anschlusstechnik enorme Verbreitung gefunden. Beispielsweise werden Sie für die werkzeugloseVerdrahtung von Lampenfassungen genutzt.From the non-assignable prior art, such terminal contacts are well known and have found enormous use in electrical connection technology. For example, they are used for tool-free wiring of lamp sockets.

Üblicherweise verfügt ein Fassungskörper über mehrere Öffnungen zum Einstecken von Anschlusskabeln. Hinter diesen Öffnungen ist ein Kontaktfeld angeordnet. Ein Federschenkel liegt vorgespannt mit seinem freien Ende auf dem Kontaktfeld auf und ist - einen Winkel zwischen sich und dem Kontaktfeld einschließend - in Leitereinschubrichtung orientiert. Wird nun zur Verdrahtung der Fassung ein Leiter mit seinem abisolierten Ende in die Anschlussöffnungdes Fassungskörpers eingeschoben, so schiebt er sich unter den Federschenkel und lenkt diesen federrückstellelastischaus. In Folge dessen ist nach Abschluss des Einschubvorgangs das abisolierte Ende der Anschlussleitung zwischen Kontaktfeld und Federschenkel geklemmt. Die Orientierung des Federschenkels in Einschubrichtung und schräg auf das Kontaktfeld zulaufend hat den wesentlichen Vorteil einer einfachen, werkzeuglosen Montage, einer sicheren Kontaktierung und einer Rückzugssicherung.Usually, a socket body has a plurality of openings for the insertion of connecting cables. Behind these openings, a contact field is arranged. A spring leg is biased with its free end on the contact pad and is - including an angle between itself and the contact field - oriented in the conductor insertion direction. Now, if a conductor is inserted with its stripped end into the connection opening of the socket body for wiring the socket, it slides under the spring leg and deflects this spring return resiliently. As a result, after completion of the insertion process, the stripped end of the connecting lead between the contact field and spring leg is clamped. The orientation of the spring leg in the insertion direction and obliquely tapered to the contact field has the significant advantage of a simple, tool-free installation, a secure contact and a retraction protection.

Diese Art von Klemmkontakt hat sich in der Anschlusstechnik hinlänglich bewährt und wird vielfältig eingesetzt, da er sich sehr gut für den werkzeuglosen Anschluss elektrischer Leiter eignet. Es gibt jedoch spezielle Anwendungen, insbesondere in der Beleuchtungstechnik, bei denen der Einsatz solcher Klemmkontakte mitunter Schwierigkeiten bereitet. Hierzu zählen beispielsweise Lampenfassungen für Halogenniedervoltlampen, bei welchen hohe Ströme vom Anschlussleiter auf den Fassungskontakt zu übertragen sind. Hierzu bedarf es eines erheblich gegen das Kontaktfeldvorgespannten Federschenkels um die notwendigen Kontaktkräfte sicherzustellen. Das Einschieben des Leiters zwischen Federschenkel und Kontaktfeld für den elektrischen Anschluss bedarf deshalb entsprechender Kräfte. Um diese aufbringen zu können, sind die Anschlussleiter als Massivdraht ausgeführt. Flexible feindrähtige Leiter sind regelmäßig durch Aderendhülsen oder Verzinnung versteift. Anderenfalls besteht die Gefahr, dass der Leiter selbst aufgrund der hohen Einschubkräfte abknickt und eine sichere Kontaktierung nicht zustande kommt.This type of terminal contact has proven itself in the connection technology and is widely used because it is very well suited for the tool-free connection of electrical conductors. However, there are special applications, especially in lighting technology, where the use of such terminal contacts sometimes causes difficulties. These include, for example, lampholders for low-voltage halogen lamps, in which high currents are to be transferred from the connection conductor to the socket contact. For this purpose, it requires a considerably against the contact field biased spring leg to ensure the necessary contact forces. The insertion of the conductor between the spring leg and contact pad for the electrical connection therefore requires appropriate forces. To apply these, the connecting conductors are designed as solid wire. Flexible fine-stranded conductors are regularly stiffened by wire end sleeves or tin plating. Otherwise, there is a risk that the conductor itself kinks due to the high insertion forces and secure contact does not come about.

Um diesem Problem in der Praxis zu begegnen, werden dort, wo hohe Ströme zu übertragen sind, die elektrischen Leiter unter anderem mittels sogenannter Käfigzugfedern auf dem zugehörigen Kontaktfeldgehalten. Eine solche Käfigzugfeder ist beispielsweise in DE 102007047327 A1 offenbart. Wesentlicher Unterschied zum eingangs genannten Stand der Technik besteht darin, dass der Leiter quasi kraftfrei in die Klemmstelle des Kontaktes eingeführt werden kann. Hierbei durchtaucht das abisolierte Leiterende berührungslos eine Öffnung in einer Zugfeder, bis sie auf einen Spannhebel trifft. Die Einschubbewegung führt zu einem Lösen von Spannhebel und Zugfeder. Die Zugfeder schnappt in ihre Geschlossen-Stellung, wobei der Käfig den Leiter gegen das Kontaktfeld drängt. Durch eine gesonderte Eingriffsöffnung lässt sich die Feder mit einem geeigneten Werkzeug, beispielsweise einem Schraubendreher, wieder öffnen. Die Käfigzugfeder gemäß DE 102007047327 A1 gestattet lediglich bei Erstmontage einen widerstandslosen Einschub des Leiters. Im Anschluss an die Erstmontage - bzw. bei erneutem Anschluss im Servicefall - ist das Öffnen der Käfigzugfeder mit einem Werkzeug erforderlich.In order to meet this problem in practice, where high currents are to be transmitted, the electrical conductors are held, inter alia, by means of so-called cage tension springs on the associated contact field. Such a cage tension spring is for example in DE 102007047327 A1 disclosed. Significant difference from the prior art mentioned above is that the conductor can be introduced into the nip of the contact virtually without force. In this case, the stripped conductor end passes without contact through an opening in a tension spring until it encounters a tension lever. The insertion movement leads to a release of tensioning lever and tension spring. The tension spring snaps into its closed position, with the cage urging the conductor against the contact pad. By a separate engagement opening, the spring with a suitable tool, such as a screwdriver, open again. The cage tension according to DE 102007047327 A1 only allowed at initial installation a resistance insertion of the conductor. Following initial assembly - or re-connection in case of service - it is necessary to open the cage tension spring with a tool.

Käfigzugfedern sind in der Regel in der Lage, die erforderlichen Kontaktkräfte zwischen Leiter und Kontaktfeld sicherzustellen. Von Nachteil ist jedoch der durch die Käfigzugfeder bedingte, gegenüber dem gattungsgemäßen Stand der Technik größere Bauraum. Ferner von Nachteil ist, dass in eine geschlossene Käfigzugfeder ein Leiter nur eingeführt werden kann, nachdem die Käfigzugfeder mit einem gesonderten Werkzeug in Offen-Stellung bewegt wurde.Cage tension springs are usually able to ensure the required contact forces between the conductor and contact pad. The disadvantage, however, is the conditional by the cage clamp, compared to the generic state of the art larger space. Another disadvantage is that in a closed cage tension spring a conductor can only be introduced after the cage clamp was moved with a separate tool in the open position.

Aufgabe der Erfindung ist es, einen neuartigen Klemmkontakt zu schaffen, der den Leiter mit der für die Übertragung hoher Ströme erforderlichen Kraft auf dem Kontaktfeld hält und eine werkzeuglose Montage der Anschlussleitungen auch bei geschlossenem Kontakt ermöglicht.The object of the invention is to provide a novel clamping contact, which holds the conductor with the force required for the transmission of high currents on the contact field and allows tool-free installation of the connection lines even when the contact is closed.

Gelöst wird die Erfindung von einem Klemmkontakt mit den Merkmalen des Anspruchs 1, insbesondere mit den kennzeichnenden Merkmalen, wonach der Klemmkontakt einen Auslösehebel umfasst, der in der Bewegungsbahn des elektrischen Leiters angeordnet ist und mit dem Federschenkel in einer den Federschenkel in einer Offenstellung haltenden Wirkverbindung steht, wobei ein erstes Einschieben des Leiters in die Klemmstelle die Wirkverbindung zwischen Auslösehebel und Federschenkel trennt und den Klemmkontakt schließt, so dass der Federschenkel den Leiter zwischen sich und dem Kontaktfeld hält.The invention is achieved by a clamping contact with the features of claim 1, in particular with the characterizing features, according to which the clamping contact comprises a release lever, which is arranged in the path of movement of the electrical conductor and is in an open position with the spring leg holding active connection wherein a first insertion of the conductor into the nip separates the operative connection between the trigger lever and the spring leg and closes the clamping contact, so that the spring leg holds the conductor between itself and the contact field.

Der wesentliche Vorteil des erfindungsgemäßen Klemmkontakts ist zunächst einmal darin zu sehen, dass eine raumsparende und kompakte Bauform erhalten geblieben ist. Darüber hinaus gestattet der durch den Auslösehebel in einer Offenstellung gesicherte Federschenkel ein quasi kraftfreies Einführen des elektrischen Leiters in die Klemmstelle. Lediglich zum Lösen der Wirkverbindung zwischen Auslösehebel und Federschenkel ist ein gewisser Kraftaufwand erforderlich. Der Federschenkel selbst kann in seiner Vorspannung ohne Berücksichtigung der Montageerfordernisse einzig und allein auf eine ausreichende Andruckkraft optimiert werden. Im Gegensatz zum gattungsgemäßen Stand der Technik muss nicht darauf geachtet werden, dass die Andruckkraft des Federschenkels bei Erstmontage noch ein Einschieben des Anschlussleiters in die Klemmstelle ermöglicht. Dies ist insbesondere im Hinblick auf die manuelle Vorkonfektionierung von Fassungen mit Anschlussleitungen in der Massenfertigung vorteilhaft.The main advantage of the terminal contact according to the invention is first of all to be seen in that a space-saving and compact design has been preserved. In addition, the spring leg secured by the release lever in an open position allows a quasi force-free insertion of the electrical conductor into the clamping point. Only to release the operative connection between the trigger and spring legs a certain amount of force is required. The spring leg itself can be optimized in its bias without taking into account the mounting requirements solely on a sufficient pressure force. In contrast to the generic state of the art, care must be taken that the pressure force of the spring leg during initial assembly still allows insertion of the connecting conductor in the nip. This is particularly advantageous in view of the manual prefabrication of sockets with connection lines in mass production.

Dennoch ist es möglich, einen ausreichend steifen Leiter weiterhin auch bei geschlossener Klemmstelle unter den Federschenkel zu schieben wie es beispielsweise im Fall eines Leitungswechsels oder einer Reparatur der Fassung erforderlich sein kann. Insoweit ist auch bei geschlossenem Klemmkontakt weiterhin ein werkzeugloses Anschließen elektrischer Leiter möglich, wobei der erhöhte Kraftaufwand für beispielsweise Reparaturarbeiten problemlos handhabbar ist.Nevertheless, it is possible to continue to push a sufficiently rigid conductor even when the nip is closed under the spring leg as it may be necessary, for example, in the case of a line change or repair of the socket. In that regard, a tool-free connection electrical conductors is also possible with closed terminal contact, the increased force required for example repair work is easy to handle.

Besonders bevorzugt ist eine Ausführungsform, die sich dadurch kennzeichnet, dass das Kontaktfeld, der Federschenkel und der Auslösehebel werkstoffeinheitlich- stoffschlüssig miteinander verbunden sind.Particularly preferred is an embodiment which is characterized in that the contact field, the spring leg and the release lever material material are materially connected to each other.

Ein derart ausgestalteter Klemmkontakt lässt sich beispielsweise durch Stanzen und anschließendes Aufrichten besonders einfach und effizient herstellen.A Klemmkontakt designed in this way can be produced in a particularly simple and efficient manner, for example by punching and subsequent erection.

Ein besonders einfacher Aufbau des Klemmkontakts sieht vor, dass der Auslösehebel den Federschenkel unmittelbar in seiner Offenstellung hält. Weiterhin ist vorgesehen, dass das den Leiter haltende freie Ende des Federschenkels v-förmig eingeschnitten ist. Der wesentliche Vorteil ist darin zu sehen, dass eine Zwei-Punkt-Anlage zwischen Federschenkel und Leiter und somit eine gute Übertragung des Anpressdrucks gewährleistet ist. Zudem verhindert das den Leiter so überfangende freie Ende ein seitliches Wegrutschen des Leiters.A particularly simple design of the terminal contact provides that the release lever holds the spring leg directly in its open position. Furthermore, it is provided that the conductor holding the free end of the spring leg is cut in a V-shape. The main advantage is the fact that a two-point system between the spring leg and conductor and thus a good transmission of the contact pressure is ensured. In addition, prevents the head so catching free end sideways slipping of the conductor.

Konkret ist vorgesehen, dass der Federschenkel eine Basis aufweist, an welcher der Auslösehebel einstückig-stoffschlüssig angeordnet ist.Specifically, it is provided that the spring leg has a base on which the release lever is integrally-cohesively arranged.

Weiterhin ist vorgesehen, dass der Auslösehebel einen zum freien Federschenkelende gerichteten Haltezapfen zur Auflage des freien Federschenkelendes in der Offenstellung aufweist.Furthermore, it is provided that the release lever has a free spring leg end directed retaining pin for supporting the free spring leg end in the open position.

Besonders vorteilhaft ist es, wenn der Federschenkel zwischen seiner Basis und seinem freien Ende eine Materialschwächungszone aufweist, die eine Verlagerung von Basis und Auslösehebel in Einschubrichtung des Leiters gestattet, insbesondere wenn die Verlagerung zumindest dem notwendigen Lösehub des Auslösehebels zum Abgleiten des freien Federschenkelendes von dem Haltezapfen entspricht.It is particularly advantageous if the spring leg has a material weakening zone between its base and its free end, which permits a displacement of the base and release lever in the direction of insertion of the conductor, in particular if the displacement at least the necessary release stroke of the release lever for sliding of the free spring leg end of the retaining pin equivalent.

Der wesentliche Vorteil dieser Ausführungsform ist darin zu sehen, dass sie hinsichtlich des Auslösehebels ohne separat zu lagernde bewegliche Teile auskommt, sondern der Federschenkel lediglich durch eine leichte Verlagerung seiner Basis lösbar ist.The main advantage of this embodiment is the fact that it does not need to be stored separately with respect to the trigger lever movable parts, but the spring leg is only solvable by a slight displacement of its base.

Schließlich ist daran gedacht, dass das Kontaktfeld Leitglieder aufweist, die den elektrischen Leiter auf einer Bewegungsbahn in Richtung Auslösehebel halten und zentrieren, wodurch ein seitliches Abgleiten des Leiters vom Kontaktfeld verhindert wird.Finally, it is envisaged that the contact pad has guide members which hold and center the electrical conductor on a path of travel in the direction of the trip lever, thereby preventing lateral slippage of the conductor from the contact pad.

Die Ausgestaltung des Kontaktfeldes in der vorgenannten Form stellt sicher, dass der Leiter direkt dem Auslösehebel zugeführt wird.The design of the contact field in the aforementioned form ensures that the conductor is fed directly to the release lever.

Nach Bestückung des Fassungskopfes 11 wird dieser unterseitig durch einen Fassungsboden 14 verschlossen.The recess 12 is accessible from the underside of the socket head ago, so that the terminal contact 13 can be inserted into the socket head 11. After assembly of the socket head 11, this is closed on the underside by a socket bottom 14.

Der Anschlusskontakt 13 umfasst zunächst ein Kontaktfeld 15 mit Führungsgliedern 16 für das abisolierte Ende 17 des Anschlussleiters 18, welches speziell bei flexiblen Leitern gegebenenfalls durch eine Aderendhülse 19 verstärkt ist.The terminal contact 13 initially comprises a contact pad 15 with guide members 16 for the stripped end 17 of the connecting conductor 18, which is reinforced, especially in flexible conductors optionally by a ferrule 19.

Weiterhin umfasst der Anschlusskontakt 13 einen Federschenkel 20, dessen freies Ende 21 der Halterung und Kontaktierung des Anschlussleiters 18 auf dem Kontaktfeld 15 dient. Ein v-förmiger Einschnitt 22 am freien Ende 21 des Federschenkels 20 gewährleistet eine Zwei-Punkt-Anlage des Federschenkels 20 am Leiter 18.Furthermore, the terminal contact 13 comprises a spring leg 20, the free end 21 of the holder and contacting the terminal conductor 18 on the contact pad 15 is used. A V-shaped notch 22 at the free end 21 of the spring leg 20 ensures a two-point contact of the spring leg 20 on the conductor 18th

Der Federschenkel 20 des Anschlusskontakts 13 geht über eine Materialschwächungszone 23 in eine Basis 24 über, an welcher ein Auslösehebel 25 angeordnet ist. Über ein Verbindungsglied 26 ist das Kontaktfeld 15 mit Federschenkel 20 verbunden, so dass der in seiner Gesamtheit mit 13 bezeichnete Klemmkontakt ein einstückig stoffschlüssiges Bauteil bildet und beispielsweise aus einem Stanzling aufgerichtet werden kann. Alternativ kann das Kontaktfeld 15 ein separates Bauteil mit besserem elektrischen Leitwert oder mit einer veredelten Oberfläche sein, welches mit dem Federschenkel 20 mechanisch verbunden ist.The spring leg 20 of the terminal 13 passes through a material weakening zone 23 in a base 24 on which a release lever 25 is arranged. Via a connecting member 26, the contact pad 15 is connected to the spring leg 20, so that the designated in its entirety by 13 clamping contact forms an integral cohesive component and can be erected for example from a stamped product. Alternatively, the contact pad 15 may be a separate component with better electrical conductance or with a finished surface which is mechanically connected to the spring leg 20.

Die Darstellung in Fig. 2 entspricht im Wesentlichen derjenigen in Fig. 1. Der elektrische Leiter 18 ist durch einen vom Fassungsboden 14 ausgebildeten Einsteckkanal 27 in das Fassungsgehäuse 10 eingeschoben worden. Das abisolierte Ende 17 mit seiner Aderendhülse 19 ist im Wirkbereich des Klemmkontaktes 13 auf dem Kontaktfeld 15 angeordnet. Die Führungsglieder 16 unterstützen die Einschubbewegung des Leiters 18 und helfen, diesen zentriert auf den Auslösehebel 25 hin zu bewegen.The representation in Fig. 2 is essentially the same as in Fig. 1 , The electrical conductor 18 has been inserted into the socket housing 10 through a plug-in channel 27 formed by the socket bottom 14. The stripped end 17 with its wire end sleeve 19 is in the effective range of the clamping contact 13 on the contact pad 15th arranged. The guide members 16 support the insertion movement of the conductor 18 and help to move it centered on the release lever 25 back.

Der Leiter 18 lässt sich quasi kraftfrei in die von Kontaktfeld 15 und Federschenkel 20 gebildete Klemmstelle einführen, da der Federschenkel 20, insbesondere dessen freies Ende 21, von Haltezapfen 28 des Auslösehebels 25 in einer Offen-Stellung gehalten ist. Hierzu liegt das freie Ende 21 auf den Haltezapfen 28 (hier zwei) des Auslösehebels 25 auf. In dieser Lage ist das freie Ende 21 des Federschenkels 20 außerhalb der Bewegungsbahn des Leiters 18 angeordnet. Der Federschenkel 20 ist entgegen seiner Federrückstellkraft auf den Haltezapfen 28 des Auslösehebels 25 gelagert.The conductor 18 can be virtually force-free in the contact pad 15 and spring leg 20 formed clamping point, since the spring leg 20, in particular its free end 21, held by retaining pin 28 of the trigger lever 25 in an open position. For this purpose, the free end 21 rests on the holding pin 28 (here two) of the release lever 25. In this position, the free end 21 of the spring leg 20 is disposed outside the path of movement of the conductor 18. The spring leg 20 is mounted against the spring restoring force on the retaining pin 28 of the release lever 25.

In Fig. 3 wurde die Einschubbewegung des Leiters 18 in Richtung des Pfeils x gegenüber der Darstellung in Fig. 2 fortgesetzt. In Folge dessen trifft die Stirnfläche 29 des abisolierten Leiterendes 17 gegen den Auslösehebel 25. Bei weiter fortgesetzter Bewegung x wird auch der Auslösehebel 25 und mit diesem bewegungseinheitlich die Basis 24 in Einschubrichtung x verlagert. Dies führt zu einer Relativverschiebung der Haltezapfen 28 gegenüber dem freien Ende 21 des Federschenkels 20. In Folge dessen rutschen die Haltezapfen 28 des Auslösehebels 25 unter dem freien Ende 21 des Federschenkels 20 weg und geben diesen frei.In Fig. 3 was the insertion movement of the conductor 18 in the direction of the arrow x with respect to the representation in Fig. 2 continued. As a result, meets the end face 29 of the stripped conductor end 17 against the release lever 25. With continued movement x and the release lever 25 and with this movement unit, the base 24 is displaced in the insertion direction x. This leads to a relative displacement of the retaining pin 28 relative to the free end 21 of the spring leg 20. As a result, slip the retaining pin 28 of the trigger lever 25 under the free end 21 of the spring leg 20 away and give it free.

Zu beachten ist hierbei, dass bereits eine geringe Verlagerung - ein geringer Lösehub - des Auslösehebels 25 ausreichend ist, um das freie Ende 21 des Federschenkels 20 zu lösen. Die Führungsglieder 16 unterstützen und stabilisieren die Einschubbewegung x. Der Lösehub des Auslösehebels 25 bedarf lediglich einer geringen Einschubkraft.It should be noted here that even a small displacement - a small release stroke - the release lever 25 is sufficient to release the free end 21 of the spring leg 20. The guide members 16 support and stabilize the insertion movement x. The release stroke of the release lever 25 requires only a small insertion force.

Bedingt durch den geringen Lösehub und den geringen Kraftaufwand zur Ausführung desselben ist eine Aderendhülse auf dem abisolierten Ende des Leiters 18 nicht unbedingt erforderlich. Auch ohne zusätzliche Aussteifung besteht beim Auftreffen der Stirnfläche 29 des Leiters 18 keine Gefahr, dass dessen abisoliertes Ende 17 abknickt. Hinzu kommt, dass bei einer maschinellen Montage der Anschlussleitungen 18 diese mit einer vergleichsweise hohen Geschwindigkeit in die Klemmstelle eingeführt werden und auf den Auslösehebel 25 treffen. Die hierdurch erreichte Impulsenergie im Zusammenhang mit der durch Massenträgheit begründeten, verspäteten Verformung ermöglicht einen ausreichenden Lösehub auch bei vergleichsweise labilen Leiterenden 17. Die Materialschwächungszone 23 zwischen Basis 24 und Federschenkel 20 vermindert den Kraftaufwand zum Ausführen des Lösehubes weiter.Due to the low Lösehub and the low effort to perform the same is a wire end ferrule on the stripped end of the conductor 18 is not essential. Even without additional stiffening there is no danger that its stripped end 17 kinks when hitting the end face 29 of the conductor 18. In addition, with a mechanical assembly of the connection lines 18, these are introduced into the clamping point at a comparatively high speed and strike the release lever 25. The pulse energy thus achieved in connection with the delayed deformation due to inertia allows a sufficient release stroke even with comparatively unstable conductor ends 17. The material weakening zone 23 between base 24 and spring leg 20 further reduces the force required to carry out the release stroke.

Als Folge des Lösehubes des Auslösehebels 25 in Fig. 3 schnappt der Federschenkel 20 mit seinem freien Ende 21 in Richtung Kontaktfeld 15 und schließt so den Klemmkontakt 13 bzw. die Klemmstelle. Das Leiterende 17 wird mit einem ausreichenden Anpressdruck durch den Federschenkel 20 auf dem Kontaktfeld gehalten. Gleichzeitig bildet der in Leitereinschubrichtung x orientierte und einen Winkel mit dem Kontaktfeld 15 einschließende Federschenkel 20 eine Rückzugssicherung für den Leiter 18. Der v-förmige Einschnitt 22 des Federschenkels 20 bewirkt eine Zwei-Punkt-Anlage zwischen dem freien Ende 21 und dem Leiterende 17.As a result of the release stroke of the release lever 25 in Fig. 3 snaps the spring leg 20 with its free end 21 in the direction of the contact pad 15 and thus closes the terminal contact 13 and the terminal point. The conductor end 17 is held with a sufficient contact pressure by the spring leg 20 on the contact pad. At the same time, the spring leg 20 oriented in the conductor insertion direction x and enclosing an angle with the contact field 15 forms a retraction securing device for the conductor 18. The V-shaped recess 22 of the spring leg 20 effects a two-point contact between the free end 21 and the conductor end 17.

Der erfindungsgemäße Klemmkontakt 13 hat folglich den erheblichen Vorteil, dass ein Anschlussleiter 18 kraftfrei in die Klemmstelle eingeführt werden kann, sofern der Federschenkel 20 sich in Offen-Stellung befindet.The inventive clamping contact 13 thus has the considerable advantage that a connection conductor 18 can be inserted force-free into the clamping point, provided that the spring leg 20 is in the open position.

Lediglich ein geringer Kraftaufwand ist erforderlich, um bei der Erstmontage des Leiters den Lösehub des Auslösehebels 25 auszuführen. Hierdurch wird die Verbindung zwischen Haltezapfen 28 und freiem Ende 21 des Federschenkels 20 gelöst, welche den Federschenkel 20 in seiner Offen-Stellung hält. Der Federschenkel 20 schnappt federrückstellelastisch in seine Geschlossen-Stellung und hält das freie Ende 17 des Leiters 18 mit der zur Übertragung hoher Ströme notwendigen Kraft auf dem Kontaktfeld 15.Only a small amount of force is required in order to carry out the release stroke of the release lever 25 during the initial assembly of the conductor. As a result, the connection between the retaining pin 28 and the free end 21 of the spring leg 20 is released, which holds the spring leg 20 in its open position. The spring leg 20 snaps spring return elastic in its closed position and holds the free End 17 of the conductor 18 with the force necessary for the transmission of high currents on the contact field 15th

Bei Erstmontage ist der Kraftaufwand zum Festlegen des Leiterendes 17 in der Klemmstelle somit erheblich geringer als bei Klemmkontakten aus dem Stand der Technik, bei welchen das Leiterende 17 gegen die Federrückstellkraft des Federschenkels 20 zwischen diesen und das Kontaktfeld 15 eingeschoben werden muss.At initial installation of the force required to set the conductor end 17 in the nip is thus considerably lower than in prior art terminal contacts, in which the conductor end 17 must be inserted against the spring restoring force of the spring leg 20 between them and the contact pad 15.

Der erfindungsgemäße Klemmkontakt 13 ermöglicht in Folge dessen ein einfaches und schraubenloses Konnektieren des elektrischen Leiters.As a result, the clamping contact 13 according to the invention enables a simple and screwless connection of the electrical conductor.

Im Hinblick auf Fig. 5 offenbart sich jedoch ein weiterer wesentlicher Vorteil des Klemmkontaktes 13 der Erfindung. In Fig. 5 ist der Klemmkontakt 13 in Geschlossen-Stellung dargestellt, ohne dass ein Leiter 18 zwischen Federschenkel 20 und Kontaktfeld 15 angeordnet ist. In Fig. 5 nimmt der Federschenkel insoweit die in Einschubrichtung x orientierte und einen Winkel mit dem Kontaktfeld 15 einschließende Stellung eines Klemmkontaktes gemäß Oberbegriff des Hauptanspruchs ein. Im Gegensatz zu den eingangs beschriebenen, heterogenen Käfigzugfedern ist es beim erfindungsgemäßen Klemmkontakt 13 jedoch auch in Geschlossen-Stellung möglich, einen Leiter 18 ohne zusätzliches Werkzeug zum Öffnen des Klemmkontaktes 13 in die Klemmstelle einzuschieben. Hierzu muss lediglich die Federrückstellkraft des Federschenkels 20 überwunden werden.With regard Fig. 5 however, another significant advantage of the clamping contact 13 of the invention is disclosed. In Fig. 5 the clamping contact 13 is shown in the closed position, without a conductor 18 between spring leg 20 and contact pad 15 is arranged. In Fig. 5 takes the spring leg so far in the insertion direction x oriented and an angle with the contact field 15 enclosing position of a terminal contact according to the preamble of the main claim. In contrast to the above-described, heterogeneous Käfigzugfedern it is possible in the clamping contact 13 according to the invention, however, also in the closed position, to insert a conductor 18 without additional tool for opening the clamping contact 13 in the nip. For this purpose, only the spring restoring force of the spring leg 20 must be overcome.
