- the first Kleitimstoff 2 is provided with a first receiving space 7 for at least one conductor.

- the clamping piece 8 has a profile with a longitudinal web 10 and a transverse web 11, wherein the second receiving space 9 is given a shape that resembles a horizontally mirrored keyhole.
- the clamping frame 6 is also provided with an opening 12 in which the longitudinal web 10 of the clamping piece 8 is arranged.

ELEKTRISCHE ANSCHLUSSKLEMMEELECTRICAL TERMINAL
Die Erfindung bezieht sich auf eine Anschlussklemme mit einem ersten Klernrnmittel, welches mit einem Druckstück, einer Klemmschraube und einem Klemmrahmen versehen ist, wobei der Klemmrahmen einen ersten Aufnahmeraum für zumindest einen Leiter, und ein darin angeordnetes Klemmstück aufweist.The invention relates to a connecting terminal with a first Klernrnmittel, which is provided with a pressure piece, a clamping screw and a clamping frame, the clamping frame having a first receiving space for at least one conductor, and a clamping piece arranged therein.
Eine Anschluss- oder Verbindungsklemme dient zum Verbinden, Anschließen und Abzweigen eines oder mehrerer Strompfade, der bzw. die betriebsmäßig nicht unterbrochen werden.A connection or connection terminal is used to connect, connect and branch one or more current paths that are not interrupted during operation.
Aus der DE 693 02 103 T2 ist eine Anschlussklemme bekannt, die als universelle Anschlussklemme ausgebildet ist.From DE 693 02 103 T2 a connection terminal is known which is designed as a universal connection terminal.
Der Erfindung liegt die Aufgabe zugrunde eine Anschlussklemme anzugeben, bei der eine weitere Anschlussmöglichkeit gegeben sein soll.The invention is based on the object of specifying a connection terminal in which a further connection possibility is to be given.
Bei der aus dem Stand der Technik bekannten Anschlussklemme wird von einem unterteilten Aufnahmeraum ausgegangen, so dass mehrfache Anschlussmöglichkeiten gegeben sind. Der der neuen Idee zugrundeliegende erfinderische Gedanke besteht darin, innerhalb dieses unterteilten Aufnahmeraums einen weiteren Aufnahmeraum zu bilden, wobei das bislang nur als Festkontakt dienende Klemmstück einbezogen ist.In the case of the connecting terminal known from the prior art, a subdivided receiving space is assumed, so that there are multiple connection options. The inventive idea on which the new idea is based is to form a further receiving space within this subdivided receiving space, the clamping piece which has so far only been used as a fixed contact being included.
Diese Aufgabe wird durch eine Anschlussklemme der eingangs genannten Art gelöst, bei der erfindungsgemäß das Klemmstück einen zweiten Aufnahmeraum für zumindest einen weiteren Leiter aufweist, wodurch ein zweites Klemmmittel gebildet ist.This object is achieved by a connection terminal of the type mentioned at the outset, in which, according to the invention, the clamping piece has a second receiving space for at least one further conductor, as a result of which a second clamping means is formed.
Hieraus ergibt sich neben der Anschlussmöglichkeit eines Leiters im ersten Aufnahmeraum des ersten Klemmmittels die Möglichkeit einen weiteren Leiter, insbesondere mit verschiede- nen Ausführungen, Abmessungen und Lagen im zweiten Aufnahmeraum des zweiten Klemmmittels anzuklemmen. Auf eine standardisierte Klemmenöffnung kann daher verzichtet werden. Das bereits vorhandene Klemmstück erlaubt zudem eine einfache und demnach kostengünstige Ausgestaltung des zweiten Klemmmittels. Grundsätzlich ist dennoch eine konventionelle Anschlussmöglichkeit innerhalb des ersten Aufnahmeraums gegeben. Die Erfindung eignet sich insbesondere für Reiheneinbaugeräte, wie z.B. ein Relais, ein Schütz, ein Leitungsschutz- Schalter, ein Leistungs- oder Motorschutzschalter.In addition to the possibility of connecting a conductor in the first receiving space of the first clamping means, this results in the possibility of a further conductor, in particular with different NEN versions, dimensions and positions to clamp in the second receiving space of the second clamping means. A standardized terminal opening can therefore be dispensed with. The existing clamping piece also allows a simple and therefore inexpensive design of the second clamping means. Basically, there is still a conventional connection option within the first recording room. The invention is particularly suitable for modular devices, such as a relay, a contactor, a circuit breaker, a circuit breaker or motor protection switch.
In einer bevorzugten Ausgestaltung weist das Klemmstück ein Profil mit einem Längssteg und einem Quersteg auf, wodurch mit einfachen Mitteln eine geometrisch günstige Ausgestaltung gegeben ist. Dies bezieht sich insbesondere auf die Bildung des zweiten Aufnahmeraums, auf die Funktion des Querstegs als Gegendruckplatte für das Druckstück und auf die Funktion des Längsstegs als relativbewegbares Abisolier- und Klemmelement.In a preferred embodiment, the clamping piece has a profile with a longitudinal web and a transverse web, which means that a geometrically favorable configuration is provided with simple means. This relates in particular to the formation of the second receiving space, to the function of the crossbar as a counterpressure plate for the pressure piece and to the function of the longitudinal web as a stripping and clamping element which can be moved relatively.
Mit Vorteil weist der zweite Aufnahmeraum eine Form auf, die einem Schlüsselloch ähnelt derart, dass ein in einen Einführungsbereich des Aufnahmeraums einzuführender Leiter auf Grund einer Relativbewegung zwischen dem Klemmrahmen und dem Klemmstück in einen Verjüngungsbereich gepresst wird und da- durch ggf. abisoliert und geklemmt wird.Advantageously, the second receiving space has a shape that resembles a keyhole in such a way that a conductor to be inserted into an insertion area of the receiving space is pressed into a tapering area due to a relative movement between the clamping frame and the clamping piece and is thereby stripped and clamped if necessary ,
Vorteilhafterweise ist der Klemmrahmen mit einer Öffnung zur Durchführung des Längssteges des Klemmstücks versehen. Durch die passgenaue Öffnung ist in Verbindung mit dem Längssteg des Klemmstücks ein wirkungsvolles Scherelement gegeben, welches ein Abisolieren und ein Klemmen eines Leiters begünstigt.The clamping frame is advantageously provided with an opening for the passage of the longitudinal web of the clamping piece. Due to the precisely fitting opening in connection with the longitudinal web of the clamping piece, an effective shear element is provided which promotes stripping and pinching of a conductor.
Zweckmäßigerweise ist das Klemmstück gehäusefest ausgebildet, wodurch sich einerseits die Anschluss lemme in einem Gehäuse positionieren lässt und andererseits eine elektrische Verbindung zu einem Gerät oder ähnlichem gegeben ist. Mit Vorteil ist das Klemmstück als Abisoliermittel ausgebildet, wodurch auch nicht abisolierte Leiter in den zweiten Aufnahmeraum der Anschlussklemme eingeführt und beim Klemm- Vorgang sowohl abisoliert als auch geklemmt werden können.The clamping piece is expediently designed to be fixed to the housing, as a result of which, on the one hand, the connection terminal can be positioned in a housing and, on the other hand, there is an electrical connection to a device or the like. The clamping piece is advantageously designed as a stripping means, so that non-stripped conductors can also be inserted into the second receiving space of the connection terminal and can be stripped and clamped during the clamping process.
Weitere Vorteile und Details der Erfindung werden nachfolgend beispielhaft anhand der Zeichnung näher erläutert. Es zeigen:Further advantages and details of the invention are explained in more detail below by way of example with reference to the drawing. Show it:

Im nachfolgenden Text sind gleiche Teile der Figuren mit gleichen Bezugszeichen oder sinngemäß mit ähnlichen Bezugszeichen versehen.In the following text, identical parts of the figures are provided with the same reference symbols or, analogously, with similar reference symbols.
FIG 1 und FIG 2 zeigen eine Anschlussklemme 1 mit einem ersten und einem zweiten Klemmmittel 2 bzw. 3. Das erste und das zweite Klemmmittel 2 bzw. 3 sind mit einem Druckstück 4 und einer Klemmschraube 5 versehen. Das erste und das zweite Klemmmittel 2 bzw. 3 weisen einen gemeinsamen Klemmrahmen 6 auf. Das erste Kleitimmittel 2 ist mit einem ersten Aufnahme- raum 7 für zumindest einen Leiter versehen.1 and 2 show a connection terminal 1 with a first and a second clamping means 2 and 3. The first and the second clamping means 2 and 3 are provided with a pressure piece 4 and a clamping screw 5. The first and the second clamping means 2 and 3 have a common clamping frame 6. The first Kleitimmittel 2 is provided with a first receiving space 7 for at least one conductor.
Im ersten Aufnahmeraum 7 ist ein Klemmstück 8 angeordnet, welches einen zweiten Aufnahmeraum 9 für zumindest einen wei- teren Leiter aufweist, wodurch das zweite Klemmmittel 3 gebildet ist. Das Klemmstück 8 weist dabei ein Profil mit einem Längssteg 10 und einem Quersteg 11 auf, wobei dem zweiten Aufnahmeraum 9 eine Form gegeben ist, die einem horizontal gespiegelten Schlüsselloch ähnelt. Der Klemmrahmen 6 ist zudem mit einer Öffnung 12 versehen, in dem der Längssteg 10 des Klemmstücks 8 angeordnet ist. Die Öffnung 12 des Klemm- rahmens 6 ist in ihrer Form, Gestalt und in ihren Abmessungen der - ggf. auch variierbaren - Geometrie des Längssteges 10 derart angepasst, dass eine präzise Passform gegeben ist. An der Kontur der Öffnung 12 ist darüber hinaus zumindest eine Schneide 13 ausgebildet.A clamping piece 8 is arranged in the first receiving space 7 and has a second receiving space 9 for at least one white teren conductor, whereby the second clamping means 3 is formed. The clamping piece 8 has a profile with a longitudinal web 10 and a transverse web 11, wherein the second receiving space 9 is given a shape that resembles a horizontally mirrored keyhole. The clamping frame 6 is also provided with an opening 12 in which the longitudinal web 10 of the clamping piece 8 is arranged. The shape, shape and dimensions of the opening 12 of the clamping frame 6 are adapted to the — possibly also variable — geometry of the longitudinal web 10 in such a way that a precise fit is provided. At least one cutting edge 13 is also formed on the contour of the opening 12.
Das Druckstück 4 ist mit einem ersten und einem zweiten Steg 14 bzw. 15 U-förmig ausgebildet, wobei im ersten Steg 14 eine erste Führung 16 für den Kopf 17 der Klemmschraube 5 vorgesehen ist. Der zweite Steg 15 dient als Auflage 18 für das dem Kopf 17 gegenüberliegende Ende 19 der Klemmschraube 5. Hierbei ist die Klemmschraube 5 zwischen den beiden Stegen 14,15 angeordnet. Der zweite Steg 15 greift in den zum Druckstück 4 rechtwinklig angeordneten Klemmrahmen 6 ein. Der Klemmrahmen 6 weist eine zweite Führung 20 mit einem Innengewinde auf, in der die Klemmschraube 5 geführt ist.The pressure piece 4 is U-shaped with a first and a second web 14 or 15, a first guide 16 for the head 17 of the clamping screw 5 being provided in the first web 14. The second web 15 serves as a support 18 for the end 19 of the clamping screw 5 opposite the head 17. The clamping screw 5 is arranged between the two webs 14, 15. The second web 15 engages in the clamping frame 6 arranged at right angles to the pressure piece 4. The clamping frame 6 has a second guide 20 with an internal thread, in which the clamping screw 5 is guided.
Beide Klemmmittel 2 und 3 wie auch die zugehörigen Aufnahmeräume 7 bzw. 9 sind geschlossen, wobei das erste Klemmmittel 2 und der erste Aufnahmeraum 7 im allgemeinen zum Klemmen bzw. zur Aufnahme üblich vorbereiteter Leiter verschiedener Querschnitte dienen. Das zweite Klemmmittel 3 und der zweite Aufnahmeraum 9 können im Vergleich zum ersten Klemmmittel 2 bzw. zum ersten Aufnahmeraum 9 auch zur Aufnahme nichtabiso- lierter Leiter verwendet werden. Da der erste Aufnahmeraum 7 den zweiten Aufnahmeraum 9 beinhaltet, kann der erste Aufnah- meraum 7 zudem in sich unterteilt sein.Both clamping means 2 and 3 as well as the associated receiving spaces 7 and 9 are closed, the first clamping means 2 and the first receiving space 7 generally being used for clamping or for receiving conductors of different cross sections which are usually prepared. In comparison to the first clamping means 2 and the first receiving space 9, the second clamping means 3 and the second receiving space 9 can also be used to receive non-isolated conductors. Since the first recording room 7 contains the second receiving space 9, the first receiving space 7 can also be divided into itself.
Eine weitere Anschlussmöglichkeit bieten auch der Raum vor und hinter dem Längssteg 10 ohne allerdings vom zweiten Aufnahmeraum 9 Gebrauch zumachen.A further connection option is also provided by the space in front of and behind the longitudinal web 10, but without making use of the second receiving space 9.
Durch Verdrehen oder Anziehen der Klemmschraube 5 erfolgt eine synchrone Bewegung mit dem Druckstück 4 in Richtung Klemm- stück 8. Durch weiteres Anziehen der Klemmschraube 5 drückt das Druckstück 4 direkt auf den Quersteg 11 des Klemmstücks 8. Dadurch wird das Klemmstück 8 durch die Öffnung 12 bewegt, wobei sich der Klemmrahmen 6 und das Klemmstück 8 gegeneinander verschieben und so den zweiten Aufnahmeraum 9 verklei- nern. Demnach wird der Klemmvorgang für einen eingelegtenBy turning or tightening the clamping screw 5, a synchronous movement takes place with the pressure piece 4 in the direction of the clamping piece 8. By further tightening the clamping screw 5, the pressure piece 4 presses directly on the crosspiece 11 of the clamping piece 8. This causes the clamping piece 8 to pass through the opening 12 moves, whereby the clamping frame 6 and the clamping piece 8 move against each other and thus reduce the second receiving space 9. Accordingly, the clamping process for an inserted one
Leiter zwangsläufig eingeleitet. Mit Vorteil ist eine Klemmung eines Leiters im zweiten Aufnahmeraum 3 nicht von einer vorausgegangen Klemmung eines Leiters im ersten Aufnahmeraum 2 abhängig. Dies gilt auch für zu klemmende Leiter mit unter- schiedlichen Abmessungen. Die Anschlussklemme 1 bietet somit von Relativbewegungen einflussfreie Anschlussmöglichkeiten.Head inevitably initiated. A clamping of a conductor in the second receiving space 3 is advantageously not dependent on a previous clamping of a conductor in the first receiving space 2. This also applies to conductors to be clamped with different dimensions. Terminal 1 thus offers connection options that are not influenced by relative movements.
Der zweite Aufnahmeraum 9 weist einen Einführungsbereich 21 und einen daran anschließenden Verjüngungsbereich 22 auf. Be- findet sich im Einführungsbereich 21 des zweiten Aufnahmeraums 9 ein nicht abisolierter Leiter, wird dieser durch den vorab beschriebenen Bewegungsablauf derart in den Verjüngungsbereich 22 gepresst, dass die Schneide 13 die Isolation des Leiters unterbricht. Durch den mittels des Klemmstücks 8 und des Klemmrahmens 6 auf den Leiter übertragenen Druck, platzt zudem die Isolation an der dem Verjüngungsbereich 22 gegenüberliegenden Seite, insbesondere längsseits des geklemmten Leiters beidseitig der Berührstellen, auf und fließt seitlich ab. Unter Verformung der Leiterseele führt dies zu einer gasdichten Kontaktierung des Leiters. Die Schneide 13 kann sich vom Einführungsbereich 21 bishin zum Verjüngungsbereich 22 erstrecken, wodurch sie einen zusätzlichen Quasi-Formschluss gegen Herausziehen des Leiters bildet. Die Schneide 13 kann aus einem besonderen Material gefertigt und/oder als Kontaktfläche ausgebildet sein.The second receiving space 9 has an insertion region 21 and a tapering region 22 adjoining it. If there is a non-stripped conductor in the insertion area 21 of the second receiving space 9, the conductor is pressed into the tapered area 22 by the previously described movement sequence in such a way that the cutting edge 13 interrupts the insulation of the conductor. Due to the pressure transferred to the conductor by means of the clamping piece 8 and the clamping frame 6, the insulation also bursts on the side opposite the tapering region 22, in particular along the clamped conductor on both sides of the contact points, and flows off laterally. If the conductor core is deformed, this leads to gas-tight contacting of the conductor. The cutting edge 13 can extend from the insertion area 21 to the tapering area 22, as a result of which it forms an additional quasi-positive connection against pulling out the conductor. The cutting edge 13 can be made from a special material and / or can be designed as a contact surface.
Ist im ersten Aufnahmeraum 7 des ersten Klemmmittels 2 ein Leiter angeordnet drückt bei weiterem Anziehen der Klemmschraube 5 das Druckstück 4 zuerst auf diesen Leiter. Der Leiter gibt im Anschluss daran den Klemmdruck auf das Klemmstück 8 weiter, so dass sowohl das erste wie auch das zweite Klemmmittel 2 bzw. 3 betätigt werden. Dieser Klemmvorgang kann auch ohne einen im zweiten Aufnahmeraum 9 angeordneten Leiter erfolgen. Hierbei wird das Klemmstück 8 mit seinem Längssteg 10 so lange durch die Öffnung 12 geschoben, bis der Quersteg 11 am Boden des Klemmrahmens 6 zum Aufliegen kommt. Dadurch kann sich ein zum Klemmen des Leiters benötigter, ausreichend großer Gegendruck aufbauen. Die Anschlussklemme 1 kann demnach zum Klemmen und ggf. zum Abisolieren und Klemmen von Leitern verwendet werden, wobei der erste Aufnahmeraum 7 auch bei nicht beaufschlagtem zweiten Aufnahmeraum 9 funktionstüchtig ist und umgekehrt.If a conductor is arranged in the first receiving space 7 of the first clamping means 2, when the clamping screw 5 is tightened further, the pressure piece 4 first presses on this conductor. The conductor then passes on the clamping pressure to the clamping piece 8, so that both the first and the second clamping means 2 and 3 are actuated. This clamping process can also take place without a conductor arranged in the second receiving space 9. Here, the clamping piece 8 with its longitudinal web 10 is pushed through the opening 12 until the cross web 11 comes to rest on the bottom of the clamping frame 6. This can build up a sufficiently large counterpressure required to clamp the conductor. Accordingly, the connection terminal 1 can be used for clamping and, if necessary, for stripping and clamping conductors, the first receiving space 7 being functional even when the second receiving space 9 is not acted on, and vice versa.
In der unbetätigten Stellung der Anschlussklemme 1, der so genannten Ruhestellung, kann sich das Klemmstück 8 mittels Federkraft in einer weiteren, hier nicht gezeigten, Ausführungsvariante selbsttätig auf einem für das Einführen eines Leiters erforderlichen Niveaus im Klemmrahmen 6 halten. Wird die Anschlussklemme 1 durch das Anziehen der Klemmschraube 5 betätigt, werden beide Klemmmittel 2 und 3 aktiviert. Beim Lösen der Klemmschraube 5 wird dann das Klemmstück 8 in seine Ausgangsstellung zurückversetzt. Das zweite Klemmmittel 3 ist sozusagen bestrebt, seine ursprüngliche Lage mittels einer federwirksamen Rückstellkraft einzunehmen. In FIG 3 und FIG 4 ist das Klemmstück 8 gemäß FIG 1 als Formteil in einer Seitenansicht bzw. als Abwicklung in der Draufsicht gezeigt.In the unactuated position of the connection terminal 1, the so-called rest position, the clamping piece 8 can hold itself automatically in a further embodiment variant, not shown here, by means of spring force at a level in the clamping frame 6 required for the insertion of a conductor. If the terminal 1 is actuated by tightening the clamping screw 5, both clamping means 2 and 3 are activated. When the clamping screw 5 is loosened, the clamping piece 8 is then returned to its starting position. The second clamping means 3 is, so to speak, endeavoring to assume its original position by means of a resilient restoring force. In FIG. 3 and FIG. 4, the clamping piece 8 according to FIG. 1 is shown as a molded part in a side view or as a development in a top view.
FIG 5 zeigt die Anschlussklemme 1 gemäß FIG 1 in einem Gehäuseabschnitt 23 in einer räumlichen Ansicht. Hierbei ist das erste und das zweite Klemmmittel 2 bzw. 3 geschlossen mit jeweils einem in dem entsprechenden Aufnahmeraum 7 bzw. 9 eingeführten Leitern dargestellt. In FIG 6 und 7 ist die An- schlussklemme 1 gemäß FIG 5 in einer Seitenansicht bzw. in einer Schnittdarstellung gezeigt. Der Quersteg 11 kann beispielsweise als Kontaktfortsatz weitergeführt werden und als orts- oder gehäusefester Anschluss Bestandteil eines Gerätes sein.5 shows the connection terminal 1 according to FIG. 1 in a housing section 23 in a three-dimensional view. Here, the first and the second clamping means 2 and 3 are shown closed, each with a conductor inserted in the corresponding receiving space 7 or 9. 6 and 7, the connection terminal 1 according to FIG. 5 is shown in a side view and in a sectional view. The crosspiece 11 can be continued, for example, as a contact extension and can be part of a device as a fixed or housing-fixed connection.
Aus den vorab beschriebenen Darstellungen ergibt sich, dass beide Aufnahmeräume unabhängig voneinander, beliebig angewendet werden können.It can be seen from the representations described above that the two recording rooms can be used as desired, independently of one another.
Wesentlicher Gedanke der vorliegenden Idee ist es, eine durch das Anziehen der Klemmschraube 5 bedingte Hubbewegung auf zweierlei Arten zur Klemmung und/oder Abisolierung und/oder zur Kontaktierung eines Leiters vorteilhaft zu nutzen.An essential idea of the present idea is to advantageously use a lifting movement caused by tightening the clamping screw 5 in two ways for clamping and / or stripping and / or for contacting a conductor.
Die Anschlussklemme 1 stellt eine Kombination eines herkömmlichen Klemmmittels mit einem weiteren Klemmmittel mit einer Abisolier- oder Kontaktiereinrichtung dar. Diese Kombinationsklemme ist auch im Rahmen eines einzelnen Klemmmittels funktionstüchtig.The connection terminal 1 represents a combination of a conventional clamping means with a further clamping means with a stripping or contacting device. This combination terminal is also functional within the scope of a single clamping means.
Eine derartige Anschlussklemme kann unter anderem bei einem Relais, einem Schütz, einem Reiheneinbaugerät, einem Leitungsschutzschalter, einem Leistungs- oder Motorschutzschalter eingesetzt werden. Such a connection terminal can be used, inter alia, in a relay, a contactor, a modular installation device, a circuit breaker, a circuit breaker or motor circuit breaker.
