Description

Die Erfindung geht aus von einem Anschlusselement, welches ein Kontaktelement und ein Betätigungselement aufweist und zur mechanischen und elektrischen Kontaktierung eines Leiters dient.The invention is based on a connection element which has a contact element and an actuating element and is used for mechanical and electrical contacting of a conductor.

Derartige Anschlusselemente werden benötigt, um vorzugsweise elektrische Litzen oder Leiter mechanisch sowie elektrisch zu kontaktieren. Dabei sollen einzelne Litzenleiter oder Massivleiter eines Kabels mit einem Gerät, einem Steckverbinder, einer Schaltung oder sonstigen elektrischen Einrichtungen verbunden werden.Such connection elements are required in order to contact preferably electrical strands or conductors mechanically and electrically. Individual stranded conductors or solid conductors of a cable should be connected to a device, a connector, a circuit or other electrical equipment.

Dabei ist das Anschlusselement das Verbindungsglied zwischen dem Leiter oder der Litze und einem weiteren elektrischen Kontakt des Gerätes, des Steckverbinders oder der sonstigen elektrischen Einrichtung. Das Anschlusselement bietet eine reversible Kontaktierung, welches sowohl eine elektrische Verbindung zwischen dem Leiter und der Einrichtung gewährleistet um Signale und Strom zu übertragen, aber auch stellt das Anschlusselement die mechanische Verbindung des Leiters mit dem Gerät sicher. Solche Anschlusselemente sind seit langem aus dem Stand der Technik als Alternativen zu irreversiblen Verbindungen bekannt. So müsste ohne derartige, reversible Anschlusselemente eine Leitung zwangsläufig gelötet oder gecrimpt werden. In beiden Fällen wäre ein Lösen des Leiters oder der Litze ohne größeren mechanischen oder thermischen Aufwand nicht möglich.The connection element is the connecting element between the conductor or the stranded wire and a further electrical contact of the device, the plug connector or the other electrical device. The connection element provides reversible contacting, which ensures both an electrical connection between the conductor and the device in order to transmit signals and power, but the connection element also ensures the mechanical connection of the conductor to the device. Such connection elements have long been known from the prior art as alternatives to irreversible connections. Without such reversible connection elements, a line would inevitably have to be soldered or crimped. In both cases, it would not be possible to loosen the conductor or the stranded wire without major mechanical or thermal effort.

Die DE 10 2007 009 082 C5 zeigt einen mehrpoligen elektrischen Steckverbinder mit einem Federkontakt, wobei für jeden Leiter, der mit dem Steckverbinder verbunden werden soll, eine erste Öffnung vorgesehen ist, die dafür ausgelegt ist, den Leiter aufzunehmen. Eine zweite Öffnung, die parallel zu der ersten Öffnung verläuft, ist dafür ausgelegt ist, einen Betätigungsstift aufzunehmen, der - durch Gleiten in der zweiten Öffnung - entsprechend seiner Position auf einen Federkontakt des Steckverbinders einwirkt, um den Leiter mit dem Steckverbinder zu verriegeln oder ihn vom Steckverbinder zu lösen. Das Lösen des Leiters vom Federkontakt erfolgt mittels eines Werkzeuges, welches zum Aufhebeln des Betätigungsstiftes dient.The DE 10 2007 009 082 C5 shows a multipolar electrical connector with a spring contact, wherein for each conductor to be connected to the connector, a first opening is provided, which is designed to receive the conductor. A second opening, parallel to the first opening, is adapted to hold an actuation pin which - by sliding in the second opening - acts according to its position on a spring contact of the connector to lock the conductor with the connector or to release it from the connector. The conductor is released from the spring contact by means of a tool which is used to pry open the actuating pin.

Aus der DE 10 2013 108 116 A1 ist eine elektrische Anschlussklemme und das dazugehörige Verfahren bekannt. Die Anschlussklemme dient der Kontaktierung eines elektrischen Leiters an eine in einer Halterung aufgenommene Stromschiene. Dafür verfügt die Anschlussklemme über eine Kulissenführung, bestehend aus einer Schließ- und einer Spannkulisse, und einen Betätigungshebel, welcher in der Kulissenführung geführt ist. Die Anschlussklemme wird als eine Art Kipp-Hebelklemme dargestellt. Nachteilig ist dabei, dass der Anschluss des Leiters in zwei Schritten erfolgt.From the DE 10 2013 108 116 A1 an electrical connection terminal and the associated method are known. The connection terminal is used to make contact with an electrical conductor on a busbar received in a holder. For this purpose, the connection terminal has a link guide, consisting of a closing and a clamping link, and an actuating lever which is guided in the link guide. The connector is shown as a kind of toggle clamp. The disadvantage here is that the conductor is connected in two steps.

In der DE 20 2011 050 916 U1 ist ein Gehäuse, insbesondere einer Anschlussklemme oder dgl., mit konturgeführtem Betätigungselement offenbart. Dabei handelt es sich um ein zweitteiliges Gehäuse mit einer Steuer- und einer Gegenkontur, wobei die Steuerkontur an einem Gehäuseteil befestigt ist und die Gegenkontur an einem Betätigungsschenkel. Dabei ist der Betätigungsschenkel dreidimensional beweglich, was jedoch nachteiliger Weise einen höheren Verschleiß zur Folge hat.In the DE 20 2011 050 916 U1 A housing, in particular a connecting terminal or the like, with a contoured actuating element is disclosed. This is a two-part housing with a control contour and a mating contour, the control contour being attached to a housing part and the mating contour to an actuating arm. The actuating leg is movable in three dimensions, which, however, disadvantageously results in greater wear.

Eine Anschlussklemme zum Anschluss von Leiterenden ist aus der DE 20 2008 014 469 U1 bekannt. Die Anschlussklemme weist ein steuerkonturgeführtes Betätigungselement auf, welches ein Verrasten einer Klemmfeder in einer geöffneten Stellung zum leichteren Einführen eines elektrischen Leiters ermöglicht. Dabei ist das Betätigungselement gleichzeitig als Leiterdurchgangsöffnung definiert.A connection terminal for connecting conductor ends is from the DE 20 2008 014 469 U1 known. The connecting terminal has a control contour-guided actuating element which enables a clamping spring to latch in an open position for easier insertion of an electrical conductor. The actuating element is also defined as a conductor passage opening.

Die EP 0 365 888 A1 offenbart einen elektrischen Verbinder für flache, flexible Leiter. Dabei erfolgt die Kontaktierung der elektrischen Leiter mittels eines mehrarmigen Betätigungsmittels, welches in das Gehäuse des elektrischen Verbinders einsetzbar ist. Dies ermöglicht die gleichzeitige Kontaktierung mehrerer elektrischer Leiter, verhindert aber eine individuelle Kontaktierung. Ferner ist eine Kontaktierung von unterschiedlichen Leitern ausgeschlossen, wodurch der elektrische Verbinder nur ein spezielles Einsatzgebiet hat.The EP 0 365 888 A1 discloses an electrical connector for flat flexible conductors. The electrical conductors are contacted by means of a multi-armed actuating means which can be inserted into the housing of the electrical connector. This enables the simultaneous contacting of several electrical conductors, but prevents individual contacting. Furthermore, contacting different conductors is excluded, which means that the electrical connector only has a special field of application.

Nachteilig an den aus dem Stand der Technik bekannten Lösung ist, dass bei diesen zumeist nur ein Betätigungsvorgang - Öffnen oder Schließen - für den Nutzer komfortabel gestaltet ist. Ergonomisch ist es für den Anwender oder Monteur eines Kabels immer zweckmäßig mit einem Werkzeug, oder vorteilhaft ganz ohne Werkzeug, nur mit den bloßen Händen, eine lineare Bewegung auszuführen. So zum Beispiel das Drücken eines Betätiger. Hingegen werden komplexere Bewegungsabläufe, wie das Hebeln mit einem Schraubendreher oder anderem Werkzeug als umständlich und aufwendig erachtet.The disadvantage of the solution known from the prior art is that in these mostly only one actuation process - opening or closing - is designed to be comfortable for the user. From an ergonomic point of view, it is always practical for the user or fitter of a cable to carry out a linear movement with a tool, or advantageously completely without tools, only with their bare hands. For example, pressing an actuator. On the other hand, more complex movement sequences, such as levering with a screwdriver or other tool, are considered cumbersome and time-consuming.

Zudem ist für eine erste Montage eines Leiters eine einfache und schnelle Installation vorteilhaft. Für den Anwender ist es wünschenswert, bei der Installation einer Vielzahl von Leitern an einer Anlage, keine großen Vorbereitungen treffen zu müssen, sondern die Vielzahl der Leiter oder Litzen direkt, im besten Fall ohne Werkzeug anschließen zu können.In addition, quick and easy installation is advantageous for an initial assembly of a conductor. It is desirable for the user not to have to make any major preparations when installing a large number of conductors on a system, but rather to be able to connect the large number of conductors or strands directly, in the best case without tools.

Dies ist mit den aus dem Stand der Technik bekannten Lösungen nicht möglich. Entweder ermöglichen die Anschlusselemente dem Nutzer eine schnelle Erstmontage von Leitungen, sind dann aber bei einer erneuten Demontage und erneutem Anschluss umständlich zu handhaben. Oder für einen ersten Anschluss von Leitern ist eine gewisse Vorarbeit durch den Nutzer nötig, was eine zügige Montage einer Vielzahl von Leitern oder Litzen unmöglich macht.This is not possible with the solutions known from the prior art. The connection elements either enable the user to quickly assemble lines for the first time, but are then cumbersome when they are dismantled and reconnected. Or a certain amount of preparatory work by the user is necessary for the first connection of ladders, which makes rapid assembly of a large number of ladders or strands impossible.

AufgabenstellungTask

Der Erfindung liegt daher die Aufgabe zugrunde ein Anschlusselement vorzustellen, welches sowohl für Litzenleiter, als auch für Massivleiter geeignet ist. Das Anschlusselement soll dem Anwender eine möglichst einfache, schnelle und kraftfreie Erstinstallation ermöglichen. Zudem soll das Anschlusselement bei einer nachträglichen Deinstallation und Neuinstallation möglichst einfach und schnell bedienbar sein, ohne dass Spezialwerkzeug nötig ist oder vom Anwender komplizierte Tätigkeiten dazu erforderlich sind.The invention is therefore based on the object of presenting a connection element which is suitable for both stranded conductors and solid conductors. The connection element should provide the user with the simplest possible, enable quick and force-free initial installation. In addition, the connection element should be able to be operated as simply and quickly as possible in the event of a subsequent deinstallation and reinstallation, without the need for special tools or complicated activities for the user.

Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.The object is achieved by the characterizing features of independent claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous refinements of the invention are given in the subclaims.

Bei der Erfindung handelt es sich um ein Anschlusselement, welches aus einem Kontaktelement und einem Betätigungselement besteht. Das Kontaktelement ist als elektrisches Kontaktelement ausgebildet und zur elektrischen und mechanischen Kontaktierung eines elektrischen Litzen- oder Massivleiters vorgesehen.The invention is a connection element which consists of a contact element and an actuating element. The contact element is designed as an electrical contact element and is provided for electrical and mechanical contacting of an electrical stranded or solid conductor.

Zweckmäßig ist das Anschlusselement in einem Isolierkörper eines elektrischen Geräts, eines Steckverbinders, einer elektrischen Schaltung oder einer sonstigen elektrischen Anlage verbaut, welcher mit einem oder mehreren elektrischen Leitern oder Adern verbunden werden muss. Das Anschlusselement kann somit als Teil einer derartigen Einrichtung ausgebildet werden und zum direkten Anschluss von Leitern oder Adern an der Einrichtung genutzt werden.The connection element is expediently installed in an insulating body of an electrical device, a plug connector, an electrical circuit or some other electrical system, which must be connected to one or more electrical conductors or wires. The connection element can thus be designed as part of such a device and used for the direct connection of conductors or wires to the device.

Zur elektrischen und mechanischen Kontaktierung eines zu kontaktierenden Leiters ist an dem Kontaktelement ein beweglicher Kontaktarm vorgesehen. Je nach Ausführungsform kann dieser als separates Bauteil ausgebildet sein, welcher beweglich mit dem Kontaktelement verbunden, oder einteilig mit dem Kontaktarm ausgeführt ist. Die bevorzugte, einteilige Ausführung des Kontaktarms mit dem Kontaktelement ermöglicht eine kostengünstige Produktion im Stanz-Biege-Verfahren.A movable contact arm is provided on the contact element for electrical and mechanical contacting of a conductor to be contacted. Depending on the embodiment, this can be designed as a separate component, which is movably connected to the contact element, or is designed in one piece with the contact arm. The preferred, one-piece design of the contact arm with the contact element enables inexpensive production using the stamping and bending process.

Das Kontaktelement weist so in einer bevorzugten Ausführungsform einen Klemmbereich auf, der zwischen dem Kontaktarm und einer Kontaktfläche des Kontaktelements gebildet wird. In den Klemmbereich ist ein Leiter einführbar, welcher durch den Kontaktarm an die Kontaktfläche gepresst wird. Dafür ist der Kontaktarm so ausgeführt, dass er unter einer Vorspannung an die Kontaktfläche gepresst wird.In a preferred embodiment, the contact element thus has a clamping area which is formed between the contact arm and a contact surface of the contact element. A conductor, which is pressed against the contact surface by the contact arm, can be inserted into the clamping area. For this purpose, the contact arm is designed in such a way that it is pressed against the contact surface under a pretension.

Dafür bildet der Kontaktarm ein freies Ende sowie ein fixiertes Ende. Das fixierte Ende bildet den Übergang zum restlichen Kontaktelement und ist so ausgestaltet, dass es mechanisch flexibel ist, so dass das freie Ende des Kontaktarms beweglich ist. So kann das freie Ende von der Kontaktfläche weg gebogen werden. Die Federkraft, welche bei der elastischen Verformung im fixierten Ende erzeugt wird, federt das freie Ende selbsttätig wieder zurück und wird gegen die Kontaktfläche gedrückt.For this, the contact arm forms a free end and a fixed end. The fixed end forms the transition to the rest of the contact element and is designed in such a way that it is mechanically flexible, so that the free end of the contact arm is movable. In this way, the free end can be bent away from the contact surface. The spring force, which is generated in the fixed end during the elastic deformation, automatically springs back the free end and is pressed against the contact surface.

Die so erzeugte Bewegungsrichtung des Kontaktarms bildet eine offene Position, in welcher das freie Ende des Kontaktarms entgegen der Federkraft ausgelenkt ist, sowie eine geschlossene Position, in welcher das freie Ende des Kontaktarms durch die Federkraft an die Kontaktfläche gedrückt wird. Erfindungsgemäß sind das Betätigungselement und das Kontaktelement relativ zueinander bewegbar. Das Kontaktelement ist fest mit einem Isolierkörper verbunden, in welchem das Anschlusselement aufgenommen ist. Das Betätigungselement ist in dem Isolierkörper beweglich, vorzugsweise linear beweglich angeordnet.The direction of movement of the contact arm generated in this way forms an open position in which the free end of the contact arm is deflected against the spring force, and a closed position in which the free end of the contact arm is pressed against the contact surface by the spring force. According to the invention, the actuating element and the contact element can be moved relative to one another. The contact element is firmly connected to an insulating body in which the connection element is received. The actuating element is arranged to be movable, preferably linearly movable, in the insulating body.

Eine besondere Ausführungsform sieht vor, dass das Betätigungselement hülsenförmig ausgebildet ist. Das heißt, dass das Betätigungselement eine längliche Grundform hat, welche entlang der Länge eine durchgehende Öffnung aufweist. In dieser Ausführungsform ist das Kontaktelement in der durchgehenden Öffnung des Betätigungselements angeordnet. Das Betätigungselement umgibt somit das Kontaktelement an vier Seiten. Diese Ausführungsform ermöglicht eine besonders platzsparende Bauweise des Anschlusselements.A particular embodiment provides that the actuating element is sleeve-shaped. This means that the actuating element has an elongated basic shape which has a continuous opening along its length. In this embodiment, the contact element is arranged in the through opening of the actuating element. The The actuating element thus surrounds the contact element on four sides. This embodiment enables a particularly space-saving design of the connection element.

Erfindungsgemäß ist am Betätigungselement eine Führungskontur ausgebildet. Ein mit der Führungskontur korrespondierender Mitnehmer ist am freien Ende des Kontaktarms des Kontaktelements ausgebildet. Durch eine Führung des Mitnehmers in der Führungskontur ist die Auslenkung und Bewegung des Kontaktarms in Abhängigkeit von der relativen Position des Betätigungselements und des Kontaktelements zueinander bestimmbar. Diese erfindungsgemäße Ausgestaltung des Anschlusselements ermöglicht es, die Position des Kontaktarms (geöffnet oder geschlossen) durch Bewegung des Betätigungselements zu steuern.According to the invention, a guide contour is formed on the actuating element. A driver corresponding to the guide contour is formed at the free end of the contact arm of the contact element. By guiding the driver in the guide contour, the deflection and movement of the contact arm can be determined as a function of the relative position of the actuating element and the contact element to one another. This configuration of the connection element according to the invention makes it possible to control the position of the contact arm (open or closed) by moving the actuating element.

Eine bevorzugte Ausführungsform sieht vor den Mitnehmer als Stift oder Bolzen auszubilden, welcher quer zur Bewegungsrichtung des Kontaktarms ausgerichtet ist. Die Führungskontur ist dabei als Nut im Betätigungselement ausgebildet. So kann der als Stift oder Bolzen ausgebildete Mitnehmer in der Führungsnut entlanggleiten, wenn das Betätigungselement relativ zum Kontaktelement bewegt wird.A preferred embodiment provides for the driver to be designed as a pin or bolt, which is oriented transversely to the direction of movement of the contact arm. The guide contour is designed as a groove in the actuating element. The driver, designed as a pin or bolt, can slide along in the guide groove when the actuating element is moved relative to the contact element.

Eine Ausführungsform des Anschlusselements sieht vor, dass das freie Ende des Kontaktarms eine teilkreisförmige Bewegung um das fixierte Ende des Kontaktarms ausführt. Dadurch beschreibt die Bewegungsrichtung des Kontaktarms ebenfalls eine Kreisbahn, oder zumindest eine Teilkreisbahn, auf welcher der Kontaktarm sich bewegt.One embodiment of the connection element provides that the free end of the contact arm executes a part-circular movement around the fixed end of the contact arm. As a result, the direction of movement of the contact arm also describes a circular path, or at least a partial circular path, on which the contact arm moves.

Erfindungsgemäß beschreibt die Führungskontur im Betätigungselement zumindest zwei Bereiche, in welchen der Mitnehmer des Kontaktelements geführt ist. Einen ersten Bereich, in welchem der Mitnehmer in der geöffneten Position des Kontaktarms gehalten wird. Der erste Bereich ist dafür als Stufe ausgebildet, welche quer zur Bewegungsrichtung des Kontaktarms ausgerichtet ist. Dabei drückt die Federkraft des Kontaktarms diesen auf die Stufe des ersten Bereichs. Eine besonders bevorzugte Ausführung des ersten Bereichs sieht vor, die Stufe mit einer Vertiefung zu versehen. Der Mitnehmer kann so in der Vertiefung aufgenommen werden und das Betätigungselement dadurch in dieser geöffneten Position einrasten. Eine Bewegung des Betätigungselements kann so nicht unbeabsichtigt erfolgen. Dennoch ist nur ein geringer Kraftaufwand nötig um durch Bewegung des Betätigungselements den Mitnehmer aus der Vertiefung, entgegen der Federkraft, zu bewegen.According to the invention, the guide contour in the actuating element describes at least two areas in which the driver of the contact element is guided. A first area in which the driver is held in the open position of the contact arm. For this purpose, the first area is designed as a step which is oriented transversely to the direction of movement of the contact arm is. The spring force of the contact arm pushes it onto the step of the first area. A particularly preferred embodiment of the first area provides for the step to be provided with a depression. The driver can thus be received in the recess and the actuating element can thereby snap into this open position. A movement of the actuating element cannot take place unintentionally. Nevertheless, only a small amount of force is required to move the driver out of the recess, counter to the spring force, by moving the actuating element.

Der zweite Bereich der Führungskontur ist so ausgebildet, dass der Mitnehmer in diesem Bereich frei beweglich zwischen der geöffneten Position und geschlossenen Position beweglich ist. Der zweite Bereich ist teilkreisförmig ausgebildet, wobei die Form der Bewegungsrichtung und dem Bewegungslauf des Kontaktarms und/oder des Mitnehmers entspricht. Der Kontaktarm wird in diesem Bereich immer die geschlossene Position einnehmen, in welche er durch die Federkraft des Kontaktelements gezwungen wird.The second area of the guide contour is designed so that the driver is freely movable in this area between the open position and the closed position. The second area is partially circular, the shape corresponding to the direction of movement and the course of movement of the contact arm and / or the driver. The contact arm will always assume the closed position in this area, into which it is forced by the spring force of the contact element.

Erfindungsgemäß schließt sich der zweite Bereich direkt an den ersten Bereich der Führungskontur an. Das Anschlusselement kann so in einer geöffneten Position ausgeliefert werden, in welcher das Betätigungselement so angeordnet ist, dass der Mitnehmer sich im ersten Bereich der Führungskontur befindet. Durch eine kurze, leichte Bewegung des Betätigungselements gleitet der Mitnehmer in den zweiten Bereich der Führungskontur und kann sich entlang der teilkreisförmigen Führung frei in die geschlossene Position bewegen.According to the invention, the second area directly adjoins the first area of the guide contour. The connection element can thus be delivered in an open position in which the actuating element is arranged such that the driver is located in the first region of the guide contour. With a short, light movement of the actuating element, the driver slides into the second area of the guide contour and can move freely into the closed position along the part-circular guide.

Eine besondere Ausführungsform der Erfindung sieht vor, dass die Führungskontur einen dritten Bereich aufweist. Der dritte Bereich ist als Rampe ausgebildet und führt den Kontaktarm von der geschlossenen Position bis zur offenen Position bei einer Bewegung des Betätigungselements um die Länge des dritten Bereichs. Dabei fällt das eine Ende der Rampe, welches die geschlossene Position beschreibt, mit dem zweiten Bereich zusammen. Der dritte Bereich ist damit auf der dem ersten Bereich abgewandten Seite des zweiten Bereichs vorgesehen.A particular embodiment of the invention provides that the guide contour has a third area. The third area is designed as a ramp and guides the contact arm from the closed position to the open position when the actuating element is moved by the length of the third area. One end of the ramp, which describes the closed position, coincides with the second area. The third area is thus provided on the side of the second area facing away from the first area.

Durch die Ausführung des Betätigungselements mit einem ersten, einem zweiten und einem dritten Bereich kann das Anschlusselement drei Zustände annehmen:
Ein erster Zustand, welcher als Auslieferungszustand durch den ersten Bereich der Führungskontur definiert ist. Der Mitnehmer liegt im ersten Bereich auf der Stufe auf, wodurch das Anschlusselement in einer geöffneten Position ist. Durch die Stufe, welche quer zur Bewegungsrichtung des Kontaktarms ausgerichtet ist, ist der erste Zustand statisch.By designing the actuating element with a first, a second and a third area, the connection element can assume three states:
A first state, which is defined as the delivery state by the first area of the guide contour. The driver rests on the step in the first area, whereby the connection element is in an open position. The first state is static due to the step, which is oriented transversely to the direction of movement of the contact arm.

Ein zweiter Zustand, welcher durch den zweiten Bereich der Führungskontur definiert ist. In diesem Zustand kann sich der Kontaktarm frei von der geöffneten Position in die geschlossene Position und zurück bewegen. Durch die auf den Kontaktarm wirkende Federkraft ist dieser immer dazu veranlasst möglichst weit in die geschlossene Position zu gelangen und so einen eingeführten Leiter oder eine Litze zwischen dem Kontaktarm und der Kontaktfläche zu verklemmen. Durch die freie Bewegung des Kontaktarms und die auf diesen wirkende Federkraft ist der zweite Zustand ebenfalls statisch.A second state which is defined by the second area of the guide contour. In this condition, the contact arm is free to move from the open position to the closed position and back. The spring force acting on the contact arm causes it to move as far as possible into the closed position and thus to jam an inserted conductor or a stranded wire between the contact arm and the contact surface. Due to the free movement of the contact arm and the spring force acting on it, the second state is also static.

Der dritte Zustand wird durch die Rampe im dritten Bereich der Führungskontur definiert. Durch Bewegung des Betätigungselements wird der Kontaktarm mittels des Mitnehmers über die Rampe von der geschlossenen Position in die geöffnete Position bewegt. Dies geschieht jedoch nur, solange eine Kraft auf das Betätigungselement einwirkt. Sobald diese entfällt, wird das Betätigungselement über die Federkraft des Kontaktarms, den Mitnehmer und die Rampe wieder zurück in den zweiten Zustand gedrückt. Der dritte Zustand ist somit dynamisch.The third state is defined by the ramp in the third area of the guide contour. By moving the actuating element, the contact arm is moved from the closed position to the open position via the ramp by means of the driver. However, this only happens as long as a force is acting on the actuating element. As soon as this is omitted, the actuating element is pushed back into the second state via the spring force of the contact arm, the driver and the ramp. The third state is therefore dynamic.

Eine besondere Ausführungsform sieht vor, dass die Führungskontur einen weiteren, einen vierten Bereich ausbildet. Der vierte Bereich ist dabei ähnlich dem ersten Bereich als Stufe, welche quer zur Bewegungsrichtung ausgerichtet ist, ausgebildet. Der vierte Bereich schließt sich dabei in der geöffneten Position an den dritten Bereich an. So kann das Betätigungselement im dritten Zustand in maximal geöffneter Position weiter bewegt werden, bis der Mitnehmer in den vierten Bereich gleitet. Der vierte Bereich definiert somit, genau wie der erste Bereich, einen statischen, vierten Zustand. Auch kann die Stufe im vierten Bereich durch eine Vertiefung so modifiziert werden, dass das Betätigungselement gegen versehentliches Bewegen in den dritten Bereich gesichert ist.A special embodiment provides that the guide contour forms a further, fourth area. The fourth area is designed as a step, similar to the first area, which is oriented transversely to the direction of movement. The fourth area adjoins the third area in the open position. In the third state, the actuating element can thus be moved further in the fully open position until the driver slides into the fourth area. The fourth area thus defines, just like the first area, a static, fourth state. The step in the fourth area can also be modified by a recess in such a way that the actuating element is secured against inadvertent movement into the third area.

Eine weitere, spezielle Ausführungsform der Erfindung sieht einen fünften Bereich der Führungskontur vor. Dabei ist der fünfte Bereich am ersten Bereich, dem zweiten Bereich abgewandt, angeordnet. Der fünfte Bereich entspricht dabei in seiner Formgebung dem dritten Bereich und ist als Rampe ausgebildet. Über diese Rampe des fünften Bereichs kann der Mitnehmer bei der Montage des Anschlusselements von der kraftbeaufschlagten, geschlossenen Position in die geöffnete Position geführt werden. Durch Aufschieben des Betätigungselements auf das Kontaktelement wird so der Kontaktarm über die Rampe geöffnet bis der Mitnehmer im ersten Bereich der Führungskontur aufliegt und der erste, geöffnete Zustand des Anschlusselements hergestellt ist.Another special embodiment of the invention provides a fifth area of the guide contour. The fifth area is arranged on the first area, facing away from the second area. The shape of the fifth area corresponds to the third area and is designed as a ramp. During the assembly of the connection element, the driver can be guided from the force-loaded, closed position into the open position via this ramp of the fifth area. By sliding the actuating element onto the contact element, the contact arm is opened via the ramp until the driver rests in the first area of the guide contour and the first, open state of the connection element is established.

Eine besonders bevorzugte Ausführungsform der Erfindung sieht vor, die Führungskontur nur aus dem ersten und zweiten Bereich auszubilden. Dabei ist der zweite Bereich nicht teilkreisförmig ausgebildet, sondern rampenförmig. Dadurch kann das Anschlusselement über den zweiten Bereich der Führungskontur sowohl geschlossen als auch wieder geöffnet werden. Dafür muss das Betätigungselement nur entgegen des zweiten Bereichs bewegt werden, so dass der Mitnehmer zurück in den ersten Bereich gelangt.A particularly preferred embodiment of the invention provides for the guide contour to be formed only from the first and second areas. The second area is not designed in the shape of a part of a circle, but in the shape of a ramp. As a result, the connection element can both be closed and reopened via the second area of the guide contour. For this, the actuating element only has to be moved against the second area, so that the driver returns to the first area.

Durch die erfinderische Kombination des Mitnehmers am Kontaktarm und der Führungskontur im Betätigungselement können besonders vorteilhaft Zustände des Anschlusselements definiert werden. Dadurch kann ein für den Anwender zweckmäßiger Auslieferungszustand definiert werden, welcher eine schnelle Montage einer großen Anzahl von Anschlusselementen ermöglicht. Dennoch ist eine einfache, schnelle und ohne spezielle Werkzeuge mögliche Demontage möglich. Alle der Erfindung zu Grunde liegenden Aufgaben werden so besonders vorteilhaft gelöst.Due to the inventive combination of the driver on the contact arm and the guide contour in the actuating element, states of the connection element can be defined in a particularly advantageous manner. In this way, a delivery state that is expedient for the user can be defined, which enables a large number of connection elements to be installed quickly. Nevertheless, it can be dismantled easily, quickly and without special tools. All the objects on which the invention is based are achieved in a particularly advantageous manner.

Die Figuren enthalten teilweise vereinfachte, schematische Darstellungen. Zum Teil werden für gleiche, aber gegebenenfalls nicht identische Elemente identische Bezugszeichen verwendet. Verschiedene Ansichten gleicher Elemente könnten unterschiedlich skaliert sein.The figures contain partially simplified, schematic representations. In some cases, identical reference symbols are used for identical, but possibly not identical elements. Different views of the same elements could be scaled differently.

Die Figur 1 zeigt ein Anschlusselement 1 nach der vorliegenden Erfindung in einer perspektivischen Darstellung (Fig. 1b) sowie einer Schnittdarstellung (Fig. 1a), wobei das Anschlusselement 1 in der Fig. 1a in einem Isolierkörper 10 angeordnet ist.The Figure 1 shows a connection element 1 according to the present invention in a perspective view ( Figure 1b ) as well as a sectional view ( Fig. 1a ), the connection element 1 in the Fig. 1a is arranged in an insulating body 10.

Das Anschlusselement 1 wird aus einem hülsenförmigen Betätigungselement 3 und einem darin aufgenommenen Kontaktelement 2 gebildet. Das Betätigungselement 3 ist länglich und verfügt über eine im Wesentlichen rechteckige Grundform. Die Grundform ist der Länge nach mit einer Öffnung durchzogen. In der Öffnung ist das Kontaktelement 2 angeordnet. Im oben dargestellten Bereich des Betätigungselements 3 ist ein elektrisches Kabel dargestellt, welches zur Kontaktierung in das Anschlusselement 1 eingeführt ist. Die Öffnung des Betätigungselements 3 dient somit auch als Leiteraufnahmeöffnung des Anschlusselements 1.The connection element 1 is formed from a sleeve-shaped actuating element 3 and a contact element 2 received therein. The actuating element 3 is elongated and has an essentially rectangular basic shape. The basic shape is traversed lengthways with an opening. The contact element 2 is arranged in the opening. In the area of the actuating element 3 shown above, an electrical cable is shown, which is inserted into the connection element 1 for contacting. The opening of the actuating element 3 thus also serves as a conductor receiving opening of the connection element 1.

Im oberen Bereich des Betätigungselements 3 sind zwei Betätigungsmulden 31, 32 in das Betätigungselement 3 eingeformt. Diese sind zusätzlich zur Betätigung des Betätigungselements 3 vorgesehen. An den Betätigungsmulden 31, 32 kann beispielsweise mit einem Schraubendreher das Betätigungselement 3 von oben gedrückt oder von der Seite gehebelt werden um es weiter in den Isolierkörper 10 zu bewegen oder aus diesem heraus.In the upper region of the actuating element 3, two actuating recesses 31, 32 are molded into the actuating element 3. These are also provided for actuating the actuating element 3. On the actuating recesses 31, 32, the actuating element 3 can be pressed from above with a screwdriver, for example, or levered from the side in order to move it further into the insulating body 10 or out of it.

Im Gegensatz zum Betätigungselement 3 ist das Kontaktelement 2 nicht beweglich im Isolierkörper 10 aufgenommen. Das Kontaktelement 2 ist fest im Isolierkörper 10 befestigt. So ist eine Relativbewegung zwischen dem Betätigungselement 3 und dem Kontaktelement 2 möglich.In contrast to the actuating element 3, the contact element 2 is not movably received in the insulating body 10. The contact element 2 is firmly attached in the insulating body 10. A relative movement between the actuating element 3 and the contact element 2 is thus possible.

Das Kontaktelement 2 ist bildet eine Kontaktfläche 7 und einen der Kontaktfläche 7 gegenüberliegenden Kontaktarm 4. Der Kontaktarm 4 ist flexibel am Kontaktelement 2 einteilig angeformt. Über die Materialeigenschaft des Kontaktelements 2 definiert sich die Federsteifigkeit und somit die Kontaktkraft, mit welche der Kontaktarm 4 in Richtung der Kontaktfläche 7 gedrückt wird. Zwischen dem Kontaktarm 4 und der Kontaktfläche 7 ist ein Klemmbereich 8 gebildet, welcher zur Verklemmung und Kontaktierung des eingeführten Kabels dient. Ein freies Aderende des Kabels kann so zwischen dem Kontaktarm 4 und der Kontaktfläche 7 verklemmt, sowie mechanisch und elektrisch kontaktiert werden.The contact element 2 forms a contact surface 7 and a contact arm 4 opposite the contact surface 7. The contact arm 4 is flexibly formed in one piece on the contact element 2. The spring stiffness and thus the contact force with which the contact arm 4 is pressed in the direction of the contact surface 7 is defined by the material properties of the contact element 2. A clamping area 8 is formed between the contact arm 4 and the contact surface 7 and is used for clamping and contacting the inserted cable. A free wire end of the cable can thus be clamped between the contact arm 4 and the contact surface 7, and also mechanically and electrically contacted.

Der Kontaktarm 4 beschreibt ein fixiertes Ende und ein freies Ende 4.1. Das fixierte Ende ist der Bereich, an welchem der Kontaktarm 4 an dem Kontaktelement 2 gehalten und einteilig mit diesem verbunden ist. Das freie Ende 4.1, welches frei in Richtung der Kontaktfläche 7 federn kann, ist mit zwei Mitnehmern 5 ausgestattet. Die Mitnehmer 5 des Kontaktarms 4 sind seitlich vorgesehen und greifen in das Betätigungselement 3 ein. Im Betätigungselement 3 sind korrespondierende Führungskonturen 6 eingeformt, in welche die Mitnehmer 5 eingreifen. Die Führungskonturen 6 sind zweiseitig identisch in das Betätigungselement 3 eingebracht.The contact arm 4 describes a fixed end and a free end 4.1. The fixed end is the area in which the contact arm 4 is held on the contact element 2 and is integrally connected to it. The free end 4.1, which can spring freely in the direction of the contact surface 7, is equipped with two drivers 5. The drivers 5 of the contact arm 4 are provided laterally and engage in the actuating element 3. Corresponding guide contours 6, into which the drivers 5 engage, are formed in the actuating element 3. The guide contours 6 are introduced into the actuating element 3 identically on both sides.

Je nach relativer Stellung von Kontaktelement 2 und Betätigungselement 3 zueinander befinden sich die Mitnehmer 5 in einem anderen Bereich des Führungskonturen 6. Je nach Position ist entsprechend das freie Ende 4.1 des Kontaktarms 4 ausgerichtet. So kann eine geöffnete Position, wie auch eine geschlossene Position, des Kontaktarms 4 eingestellt werden. Auch ist eine Position von Kontaktelement 2 und Betätigungselement 3 zueinander vorgesehen, in welcher die Mitnehmer 5 frei beweglich sind. In dieser Position (vgl. Fig. 2) kann die Position des Kontaktarms 4 sich flexibel auf die Stärke eines eingeführten Kabels einstellen.Depending on the relative position of the contact element 2 and the actuating element 3 to one another, the drivers 5 are located in a different area of the guide contour 6. Depending on the position, the free end 4.1 of the contact arm 4 is aligned accordingly. In this way, an open position, as well as a closed position, of the contact arm 4 can be set. A position of the contact element 2 and the actuating element 3 with respect to one another is also provided, in which the drivers 5 are freely movable. In this position (cf. Fig. 2 ) the position of the contact arm 4 can be adjusted flexibly to the strength of an inserted cable.

Der in der Figur 1 dargestellte erste Zustand definiert den Auslieferungszustand des Anschlusselements 1. In dieser Position ist das Anschlusselement 1 weitest möglich geöffnet. Der Kontaktarm 4 hat seine maximale Auslenkung. Die Mitnehmer 5 liegen in einem ersten Bereich 6.1 der Führungskonturen 6 auf.The Indian Figure 1 The first state shown defines the delivery state of the connection element 1. In this position, the connection element 1 is open as much as possible. The contact arm 4 has its maximum deflection. The drivers 5 rest in a first area 6.1 of the guide contours 6.

Die Figur 2 zeigt das Anschlusselement 2 aus der Figur 1 in einem zweiten Zustand. In dem gezeigten, geschlossenen Zustand ist das Betätigungselement 3 weiter in den Isolierkörper 10 geschoben. Dadurch sind die Mitnehmer 5 in einen zweiten Bereich 6.2 der Führungskonturen 6 geglitten. Im zweiten Bereich 6.2 der Führungskonturen 6 können sich die Mitnehmer 5 frei entlang der Bewegungsrichtung des Kontaktarms 4 bewegen. Dadurch kann der Kontaktarm 4 frei beweglich jede Position einnehmen und so durch seine Federkraft einen eingeführten Leiter verklemmen.The Figure 2 shows the connection element 2 from FIG Figure 1 in a second state. In the closed state shown, the actuating element 3 is pushed further into the insulating body 10. As a result, the drivers 5 have slid into a second area 6.2 of the guide contours 6. In the second area 6.2 of the guide contours 6, the drivers 5 can move freely along the direction of movement of the contact arm 4. This allows the Contact arm 4 can move freely in any position and thus clamp an inserted conductor by its spring force.

In der Figur 3 ist das Anschlusselement 2 in einem vierten Zustand dargestellt. In diesem Zustand ist das Anschlusselement 2 identisch dem ersten Zustand geöffnet. Jedoch ist das Betätigungselement 3 noch weiter in den Isolierkörper 10 eingeführt, wodurch die Mitnehmer 5 in einem vierten Bereich 6.4 der Führungskonturen 6 aufliegen. Dieser vierte Zustand ist besonders vorteilhaft, da das Betätigungselement 3 durch eine einfache Drück-Bewegung betätigt werden kann um das Anschlusselement 2 wieder zu öffnen. Das Betätigungselement 3 muss nicht umständlich aus dem Isolierkörper 10 herausgezogen werden. Der Nutzer oder Anwender kann so, mit derselben einfachen Drück-Bewegung, einen elektrischen Leiter anschließen (erster Zustand - zweiter Zustand) und diesen wieder lösen (zweiter Zustand - vierter Zustand).In the Figure 3 the connection element 2 is shown in a fourth state. In this state, the connection element 2 is open identically to the first state. However, the actuating element 3 is inserted even further into the insulating body 10, as a result of which the drivers 5 rest in a fourth area 6.4 of the guide contours 6. This fourth state is particularly advantageous since the actuating element 3 can be actuated by a simple pushing movement in order to open the connecting element 2 again. The actuating element 3 does not have to be laboriously pulled out of the insulating body 10. With the same simple push movement, the user can connect an electrical conductor (first state - second state) and disconnect it again (second state - fourth state).

Um das Anschlusselement 1 vom zweiten Zustand in den vierten Zustand zu überführen ist ein dritter Zustand nötig. Der dritte Zustand beschreibt dabei die Bewegung des Betätigungselements 3 durch welche die Mitnehmer 5 über einen dritten Bereich 6.3 der Führungskonturen 6 in den vierten Bereich 6.4 bewegt werden. Der dritte Bereich 6.3 der Führungskonturen 6 ist dabei als Rampe ausgebildet, welcher den zweiten Bereich 6.2 mit dem vierten Bereich 6.4 verbindet. Über diese Rampe wird der Kontaktarm 4 entgegen der Federkraft in die geöffnete Position bewegt, welche er auch im ersten Zustand einnimmt.In order to transfer the connection element 1 from the second state to the fourth state, a third state is necessary. The third state describes the movement of the actuating element 3 by which the drivers 5 are moved over a third area 6.3 of the guide contours 6 into the fourth area 6.4. The third area 6.3 of the guide contours 6 is designed as a ramp which connects the second area 6.2 with the fourth area 6.4. Via this ramp, the contact arm 4 is moved against the spring force into the open position, which it also assumes in the first state.

Die Führungskonturen 6 weisen im ersten Bereich 6.1 und im vierten Bereich 6.4 jeweils eine Vertiefung 9 auf. Die Vertiefungen 9 sind so ausgelegt, dass die Mitnehmer 5 in diesen aufgenommen werden könne, jedoch nicht fest darin verrasten. Das heißt, dass die Mitnehmer 5 durch Verschieben des Betätigungselements 3 aus den Vertiefungen 9 gehoben werden und in einen anderen Bereich gleiten können. Die Vertiefungen 9 dienen dabei lediglich der Justierung des ersten Zustands und des vierten Zustands. Durch die Vertiefungen 9 und die darin aufgenommenen Mitnehmer 5 kann das Betätigungselement 3 nicht versehentlich mit sehr geringem Kraftaufwand bewegt werden. Der Nutzer oder Anwender muss zumindest eine bewusste, geringe Kraft aufwenden um den Zustand des Anschlusselements 1 zu beeinflussen.The guide contours 6 each have a recess 9 in the first area 6.1 and in the fourth area 6.4. The recesses 9 are designed in such a way that the drivers 5 can be received in them, but do not lock firmly in them. This means that the drivers 5 are lifted out of the recesses 9 by moving the actuating element 3 and can slide into another area. The recesses 9 are used only Adjustment of the first state and the fourth state. Due to the depressions 9 and the drivers 5 received therein, the actuating element 3 cannot be moved inadvertently with very little expenditure of force. The user or user must apply at least a conscious, slight force in order to influence the state of the connection element 1.

Eine Führungskontur 6 ist in der Figur 4 vereinzelt dargestellt. Die Führungskontur 6 ist in dem angedeutete Betätigungselement 3 (gestrichelt) als Nut oder Schlitz eingeformt. Der schematisch dargestellte Mitnehmer 5 führt durch eine relative Verschiebung des Betätigungselements 3 zum Kontaktelement 2 entlang der x-Richtung eine Bewegung entlang der Führungskontur 6 aus. Dabei wirkt eine dauerhafte Kraft in y-Richtung auf den Mitnehmer 5.A guide contour 6 is in the Figure 4 shown sporadically. The guide contour 6 is formed in the indicated actuating element 3 (dashed lines) as a groove or slot. The schematically illustrated driver 5 executes a movement along the guide contour 6 by displacing the actuating element 3 relative to the contact element 2 along the x direction. A permanent force acts on the driver 5 in the y direction.

Der fünfte Bereich 6.5 ist lediglich zu Montagzwecken vorgesehen. In diesem fünften Bereich 6.5 kann der Mitnehmer über eine Rampe in die Ausgangsposition des ersten Zustands in den ersten Bereich 6.1 bewegt werden.The fifth area 6.5 is only intended for assembly purposes. In this fifth area 6.5, the driver can be moved via a ramp into the starting position of the first state in the first area 6.1.

Der erste Bereich 6.1 stellt den ersten Zustand, den Auslieferungszustand, dar. In diesem ersten Bereich 6.1 ist der Kontaktarm 4 maximal ausgelenkt und das Anschlusselement 1 somit geöffnet.The first area 6.1 represents the first state, the delivery state. In this first area 6.1, the contact arm 4 is maximally deflected and the connection element 1 is thus open.

Der zweite Bereich 6.2 bildet den zweiten, geschlossenen Zustand des Anschlusselements 1. Hier kann der Kontaktarm 4 frei eine teilkreisförmige Bewegung um sein fixiertes Ende ausführen. Die Führungskontur 6 ist im zweiten Bereich 6.2 identisch der teilkreisförmigen Bewegung des Kontaktarms 4 ausgebildet. Eine Überführung des Anschlusselements 1 aus dem zweiten Zustand in den ersten Zustand ist nicht durch eine Verschiebung des Betätigungselements 3 möglich.The second area 6.2 forms the second, closed state of the connection element 1. Here, the contact arm 4 can freely execute a part-circular movement around its fixed end. The guide contour 6 is formed in the second area 6.2 identically to the part-circular movement of the contact arm 4. A transfer of the connection element 1 from the second state to the first state is not possible by moving the actuating element 3.

Der dritte Bereich 6.3 bildet eine Rampe identisch des fünften Bereichs 6.5. Über diese Rampe des dritten Bereichs 6.3 kann das Anschlusselement 1 wieder geöffnet werden, indem der Mitnehmer 5 über die Rampe in eine Stellung der maximalen Auslenkung des Kontaktarms 4 überführt wird. Durch die stetig auf den Mitnehmer 5 wirkende Kraft in y-Richtung, nimmt das Anschlusselement 1 in diesem dritten Bereich 6.3 immer wieder die geschlossene Position des zweiten Zustands an.The third area 6.3 forms a ramp identical to the fifth area 6.5. The connection element 1 can be opened again via this ramp of the third area 6.3, in that the driver 5 is moved via the ramp into a position of maximum deflection of the contact arm 4. Due to the force constantly acting on the driver 5 in the y direction, the connection element 1 in this third area 6.3 always assumes the closed position of the second state.

Der vierte Bereich 6.4 schließt sich als optionaler Bereich an den dritten Bereich 6.3 an. In diesem vierten Bereich 6.4 kann das Anschlusselement 1 in einem vierten, geöffneten Zustand, identisch dem ersten Zustand, fixiert bleiben. Für ein erneutes Schließen des Anschlusselements 1 muss das Betätigungselement 3 nur kurz entgegen der x-Richtung verschoben werden, bis der Mitnehmer 5 sich wieder im dritten Bereich 6.3 des Führungskontur 6 befindet und durch die auf ihn wirkende Federkraft das Anschlusselement 1 automatisch in den zweiten, geschlossenen Zustand zwingt.The fourth area 6.4 adjoins the third area 6.3 as an optional area. In this fourth area 6.4, the connection element 1 can remain fixed in a fourth, open state, identical to the first state. To close the connection element 1 again, the actuating element 3 only has to be moved briefly against the x-direction until the driver 5 is again in the third area 6.3 of the guide contour 6 and the spring force acting on it automatically moves the connection element 1 into the second, forcing closed state.
