Die Erfindung betrifft eine elektrische Anschlußanordnung zum elektrischen Anschluß eines elektrischen Geräts, insbesondere eines elektrischen Motors, mit einem Unterteil zur Aufnahme wenigstens eines geräteseitigen Kabels, mit einem Oberteil zur Aufnahme wenigstens eines anschlußseitigen Kabels und mit einem Kontaktkörper zur elektrischen Verbindung des geräteseitigen Kabels mit dem anschlußseitigen Kabel, wobei das Unterteil und das Oberteil im wesentlichen aus elektrisch isolierendem Material bestehen und in eine gemeinsame Fügeposition verbringbar sind, wodurch eine Verbindung zwischen dem anschlussseitigen Kabel und dem geräteseitigen Kabel herstellbar ist, wobei in dem Unterteil wenigstens ein Befestigungsmittel zur Befestigung wenigstens eines geräteseitigen Kabels ausgebildet ist, wobei der Kontaktkörper in dem Oberteil angeordnet ist und ein erstes Kontaktmittel und ein zweites Kontaktmittel aufweist, und wobei in der Fügeposition des Unterteils mit dem Oberteil der Kontaktkörper mit dem ersten Kontaktmittel das geräteseitige Kabel kontaktiert und mit dem zweiten Kontaktmittel das anschlussseitige Kabel kontaktierbar ist.The invention relates to an electrical connection arrangement for the electrical connection of an electrical device, in particular an electric motor, with a lower part for receiving at least one device-side cable, with an upper part for receiving at least one connection-side cable and with a contact body for electrical connection of the device-side cable to the connection side Cable, wherein the lower part and the upper part consist essentially of electrically insulating material and can be brought into a common joining position, whereby a connection between the connection-side cable and the device-side cable can be produced, wherein in the lower part at least one fastening means for fastening at least one device-side cable is formed, wherein the contact body is arranged in the upper part and having a first contact means and a second contact means, and wherein in the joining position of the lower part with the upper part d he contact body with the first contact means contacted the device side cable and the connection side cable is contactable with the second contact means.

Elektrische Anschlußanordnungen der in Rede stehenden Art sind bekannt und werden zu ganz unterschiedlichen Kontaktierungs- und Anschlußzwecken eingesetzt. Aus dem Anlagenbau sind beispielsweise Reihenklemmen bekannt, die üblicherweise in einem Schaltschrank zur Hutschienen-Montage vorgesehen sind und aus einem Unterteil und einem Oberteil bestehen (Phoenix Contact Produktkatalog " COMBICON - Leiterplattenanschluß", 2000/01, Seiten 198-212 ). Nach Aufrasten des Unterteils der Anschlußanordnung wird ein geräteseitiges Kabel, das endseitig von seiner Isolierung befreit worden ist, in das Unterteil eingesteckt und dort mit einem im Unterteil angeordneten Kontaktkörper durch eine Klemm- oder Schraubverbindung elektrisch verbunden. Anschlußseitige, abisolierte Kabel werden dann an bzw. in einem Kontaktkörper befestigt, der in dem als Steckerleiste ausgebildeten Oberteil angeordnet ist. Wenn das Oberteil und das Unterteil in die gemeinsame Fügeposition verbracht werden, wird gleichzeitig der Kontakt zwischen dem Kontaktkörper im Oberteil und dem Kontaktkörper im Unterteil und damit eine Verbindung zwischen dem anschlußseitigen und dem geräteseitigen Kabel hergestellt.Electrical connection arrangements of the type in question are known and are used for very different Kontaktierungs- and connection purposes. Terminal blocks, for example, are commonly known in plant engineering and are usually provided in a control cabinet for top hat rail mounting and consist of a base and a top section (Phoenix Contact Product Catalog). COMBICON - PCB connection ", 2000/01, pages 198-212 ). After snapping the lower part of the connection arrangement, a device-side cable, which has been freed from its end insulation, inserted into the lower part and there electrically connected to a arranged in the lower part of the contact body by a clamping or screw connection. Connection-side, stripped cable are then attached to or in a contact body, which is arranged in the upper part designed as a plug strip. When the upper part and the lower part are brought into the common joining position, at the same time the contact between the contact body in the upper part and the contact body in the lower part and thus a Connection made between the connection side and the device side cable.

Die US 4,262,985 A offenbart eine Verbindungsklemme für eine Mehrzahl von Leitern, die ein Unterteil aufweist, in dem ein Kabel von flexiblen Halteannen aufgenommen werden kann. Das Kabel wird von den Haltearmen umgriffen und in der entsprechenden Position gehalten. Des Weiteren umfasst die Verbindungsklemme ein Oberteil, in dem Kontaktelemente angeordnet sind, wobei die Kontaktelemente jeweils ein erstes und ein zweites Kontaktmittel in Form von Schneidklemmen ausweisen. Das Oberteil ist auf das Unterteil aufsteckbar, so dass jeweils ein Kontaktelement mit seinem ersten Kontaktmittel in Form der Schneidklemme ein im Unterteil gehaltenes Kabel kontaktiert, Mit dem zweiten Kontaktmittel, d.h. der zweiten Schneidklemme, kann ein weiteres Kabel kontaktiert werden. Das Oberteil und das Unterteil werden im Montagezustand von einem Abdeckelement abgedeckt.The US 4,262,985 A discloses a connection terminal for a plurality of conductors having a base in which a cable can be received by flexible retaining rings. The cable is gripped by the retaining arms and held in the appropriate position. Furthermore, the connection terminal comprises an upper part, in which contact elements are arranged, wherein the contact elements each identify a first and a second contact means in the form of insulation displacement terminals. The upper part is attachable to the lower part, so that in each case a contact element contacted with its first contact means in the form of insulation displacement cable held in the lower part, With the second contact means, ie the second insulation displacement terminal, another cable can be contacted. The upper part and the lower part are covered in the assembled state by a cover.

Die DE 102 01 495 A1 offenbart ebenfalls eine elektrische Anschlussklemme zur Kontaktierung von elektrischen Leitern. Innerhalb der Anschlussklemme ist ein schwenkbares Deckelteil an einem Basisteil fixiert, wobei das schwenkbar gelagerte Deckelteil ein von der Schwenkachse radial beabstandetes Kontaktelement aufweist. Das Deckelteil umfasst eine Mehrzahl von Kontaktelementen, die derart im Deckelteil angeordnet sind, dass bei einem Verschwenken des Deckelteils um die Schwenkachse eine Kontaktierung der im Basisteil gehaltenen Leiter, beispielsweise über Kontaktmesser, erfolgt.The DE 102 01 495 A1 also discloses an electrical terminal for contacting electrical conductors. Within the terminal a pivotable cover part is fixed to a base part, wherein the pivotally mounted cover part has a radially spaced from the pivot axis contact element. The cover part comprises a plurality of contact elements which are arranged in the cover part in such a way that upon pivoting of the cover part about the pivot axis a contacting of the conductors held in the base part takes place, for example via contact blades.

Aus der DE 102 32 281 A1 ist eine weitere elektrische Anschlußanordnung bekannt, die allerdings auf die spezielle Verwendung zum Verbinden eines Anschlußkabels an die Stator-Wicklungsenden eines Außenläufermotors zugeschnitten ist. Das Unterteil dieser Anschlußanordnung ist dabei zur Montage an dem Motorgehäuse vorgesehen, wobei die geräteseitigen Kabel - also die motorseitigen Wicklungsenden - mit in dem Unterteil angeordneten Kontaktkörpem elektrisch verbunden werden, die als Schneidkontakte ausgebildet sind; die Notwendigkeit einer vorbereitenden Abisolierung der geräteseitigen Kabelenden besteht folglich nicht. Die verteilten Kontaktkörper erstrecken sich jeweils bis zu einer in dem Unterteil ausgebildeten Steckeraufnahme, in die das als Steckerleiste ausgebildete Oberteil gesteckt werden kann. In dem Oberteil sind wiederum korrespondierende Kontaktkörper angeordnet, die mit den anschlußseitigen Kabeln elektrisch verbindbar sind. Über Steckbrücken, die in das Oberteil einsteckbar sind, können verschiedene im Oberteil angeordnete Kontaktkörper miteinander elektrisch verbunden werden, was insbesondere zu der wunschgemäßen Verschaltung der Motorwicklungen zu einer Stern- oder Dreiecksanordnung dient.From the DE 102 32 281 A1 However, a further electrical connection arrangement is known which, however, is tailored to the specific use for connecting a connection cable to the stator winding ends of an external rotor motor. The lower part of this connection arrangement is provided for mounting on the motor housing, wherein the device-side cable - so the motor-side coil ends - are electrically connected to arranged in the lower part Kontaktkörpem, which are designed as cutting contacts; the necessity of a preliminary stripping of the device-side cable ends does not exist. The distributed contact bodies each extend as far as a plug receptacle formed in the lower part into which the upper part designed as a plug strip can be inserted. By doing Upper part are in turn arranged corresponding contact body, which are electrically connected to the connection-side cables. About jumpers that can be inserted into the upper part, arranged in the upper part contact body can be electrically connected to each other, which is used in particular to the desired interconnection of the motor windings to a star or triangular arrangement.

Auch wenn der elektrische Anschluß eines Geräts mit der vorstehend beschriebenen Anschlußanordnung gegenüber dem erstgenannten Beispiel aus dem Stand der Technik aufgrund des Einsatzes von Schneidkontakten vereinfacht worden ist, ist der Anschlußvorgang trotzdem noch vergleichsweise aufwendig. Insbesondere beim Kontaktieren der geräteseitigen Kabel mit den Schneidkontakten besteht die Gefahr der mechanischen und elektrischen Verletzung, da nach Kontaktierung des geräteseitigen Kabels ein geräteseitig vorhandenes Potential - beispielsweise von einem Pufferkondensator - an den Schneidklemmen anliegt.Although the electrical connection of a device has been simplified with the above-described terminal arrangement compared to the first-mentioned example of the prior art due to the use of cutting contacts, the connection process is still relatively expensive. In particular, when contacting the device-side cable with the cutting contacts there is a risk of mechanical and electrical injury, since after contacting the device-side cable a device-side potential present - for example, from a buffer capacitor - is applied to the insulation displacement terminals.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Anschlußanordnung mit verbesserten und vereinfachten Anschlußeigenschaften zur Verfügung zu stellen, wobei insbesondere eine Mehrzahl von Leitern unabhängig voneinander kontaktierbar sein soll,The invention is therefore based on the object to provide an electrical connection arrangement with improved and simplified connection properties available, wherein in particular a plurality of conductors should be contacted independently of each other,

Die erfindungsgemäße elektrische Anschlußanozdnung, bei der diese Aufgabe gelöst ist, ist mit den Merkmalen des Patentanspruchs 1 dadurch gekennzeichnet, daß das Oberteil modular aus einzelnen Oberteilsegmenten aufgebaut ist, wobei jedes Oberteilsegment wenigstens einen Kontaktkörper umfasst.The electrical Anschlussanozdnung invention, in which this object is achieved, is characterized by the features of claim 1, characterized in that the upper part is modularly constructed of individual shell segments, each upper segment segment comprises at least one contact body.

Die erfindungsgemäße elektrische Anschlußanordnung ist in mehrfacher Hinsicht vorteilhaft. Dadurch, daß der Kontaktkörper im Oberteil der Anschlußanordnung angeordnet ist, entfällt eine Kontaktstelle gegenüber der aus der DE 102 32 281 A1 bekannten Anschlußanordnungen, nämlich die Kontaktstelle zwischen dem im Unterteil und dem im Oberteil angeordneten Kontaktkörper. Ferner wird der Kontaktierungsvorgang des geräteseitigen Kabels erheblich einfacher und sicherer, da der Kontakt zwischen Kontaktkörper und geräteseitigem Kabel erst in der Fügeposition des Unterteils und des Oberteils hergestellt wird. Damit besteht weder die Gefahr einer mechanischen Verletzung an dem die Verbindung herstellenden ersten Kontaktmittel noch die Gefahr eines elektrischen Schlages durch Berühren des möglicherweise unter Spannung stehenden ersten Kontaktmittels.The electrical connection arrangement according to the invention is advantageous in several respects. The fact that the contact body is arranged in the upper part of the terminal arrangement, eliminates a contact point with respect to the from DE 102 32 281 A1 known connection arrangements, namely the contact point between the arranged in the lower part and the upper body contact body. Furthermore, the contacting process of the device-side cable is much easier and safer, since the contact between the contact body and device-side cable is made only in the joining position of the lower part and the upper part. There is thus no danger of mechanical injury the connection means producing first contact means still the risk of electric shock by touching the possibly under tension first contact means.

Dadurch, daß das Oberteil aus mehreren Oberteilsegmenten besteht, wobei jedes Oberteilsegment wenigstens einen Kontaktkörper aufweist und separat mit dem Unterteil verbindbar ist, kann jeder Leiter separat über ein separates Oberteilsegment mit entsprechendem Kontaktkörper kontaktiert werden. Die einzelnen Oberteile können außerdem als Anschlußblock miteinander verbunden werden.Characterized in that the upper part consists of several upper segments, each upper segment having at least one contact body and is separately connectable to the lower part, each conductor can be contacted separately via a separate upper segment with a corresponding contact body. The individual tops can also be connected together as a terminal block.

Die erfindungsgemäße Anschlußanordnung läßt sich hinsichtlich ihrer Verwendbarkeit noch weiter verbessern, indem das erste Kontaktmittel des Kontaktkörpers als Schneidkontakt ausgebildet wird. Dies hat den Vorteil, daß die geräteseitigen Kabel vollständig isoliert verarbeitet werden können und nach Kontaktierung durch die Schneidkontakte eine sichere und rüttelfeste elekttische Verbindung hergestellt ist.The connection arrangement according to the invention can be further improved in terms of their usability by the first contact means of the contact body is formed as a cutting contact. This has the advantage that the device-side cable can be processed completely isolated and after contacting by the cutting contacts a secure and vibration-proof electrical connection is made.

Nach weiteren vorteilhaften Ausgestaltungen der Erfindung ist das zweite Kontaktmittel zur Kontaktierung des anschlußseitigen Kabels als Federklemme oder als Schraubklemme ausgeführt. Hierdurch ist die elektrischen und mechanischen Verbindung des anschlußseitigen Kabels mit dem Kontaktkörper nahezu beliebig oft und leicht wieder lösbaren, wobei dennoch eine sichere elektrische Verbindung gewährleistet ist.According to further advantageous embodiments of the invention, the second contact means for contacting the connection-side cable is designed as a spring clamp or as a screw terminal. As a result, the electrical and mechanical connection of the connection-side cable with the contact body is almost as often and easily detachable again, yet a secure electrical connection is ensured.

Vorzugsweise ist der Kontaktkörper ferner so ausgebildet, daß er einen Schenkel einer Steckbrücke kontaktierend aufnehmen kann, so daß wenigstens zwei Kontaktkörper elektrisch miteinander verbindbar sind. Dadurch wird insbesondere auch die Verwendbarkeit der erfindungsgemäßen Anschlußanordnung zum Anschluß eines elektrischen Motors sichergestellt, um die schon zuvor genannte Verschaltung verschiedener Wicklungen elektrischer Mehrphasenmotoren zu ermöglichen.Preferably, the contact body is further formed so that it can receive a leg of a jumper contacting, so that at least two contact bodies are electrically connected to each other. As a result, in particular the usability of the terminal arrangement according to the invention for connecting an electric motor is ensured in order to enable the previously mentioned interconnection of different windings of electric polyphase motors.

Besonders vorteilhaft ist in diesem Zusammenhang, wenn zur Aufnahme einer Steckbrücke in dem Unterteil oder dem Oberteil der Anschlußanordnung eine Ausnehmung ausgebildet ist, insbesondere derart, daß eine Berührung elektrisch leitender Teile der Steckbrücke oder eine mechanische Beeinflussung der Steckbrücke in ihrer Montageposition nicht ohne weiteres möglich ist.It is particularly advantageous in this context, if a recess is formed for receiving a jumper in the lower part or the upper part of the terminal arrangement, in particular such that a contact electrically conductive parts of the jumper or a mechanical influence on the jumper in its mounting position is not readily possible.

Bei einer weiteren Ausgestaltung der erfindungsgemäßen Anschlußanordnung hat es sich als vorteilhaft erwiesen, wenn das Befestigungsmittel in dem Unterteil in Form einer Klammer ausgebildet ist, die das Einklemmen eines geräteseitigen Kabels ohne Zuhilfenahme von Werkzeug ermöglicht. Dies vereinfacht den Anschlußvorgang an schwer zugänglichen Stellen, vor allem dort, wo nicht beidhändig gearbeitet werden kann, beispielsweise eine Hand zur Lagesicherung verwendet werden muß.In a further embodiment of the terminal arrangement according to the invention, it has proved to be advantageous if the fastening means is formed in the lower part in the form of a clamp which allows the clamping of a device-side cable without the aid of tools. This simplifies the connection process in hard to reach places, especially where you can not work both ways, for example, a hand must be used to secure the position.

In einer weiteren vorteilhaften Ausgestaltung der elektrischen Anschlußanordnung ist das Oberteil mit dem Unterteil bzw, jedes Oberteilsegment mit dem Unterteil in der Fügeposition verriegelbar, insbesondere durch dem Oberteil bzw. dem Oberteilsegment zugeordnete Rastelemente, die in Fügeposition mit korrespondierenden Rastelementausnehmungen im Unterteil der Anschlußanordnung in Eingriff bringbar sind, Besonders bevorzugt sind das Rastelement und die Rastelementausnehmung so ausgestaltet, daß sie beim Zusammenfügen des Unterteils und des Oberteils bzw. des Unterteils und des Oberteilsegments gleichsam wie eine Führung wirken und so eine exakte Positionierung des ersten Kontaktmittels gegenüber dem im Befestigungsmittel des Unterteils fixierten geräteseitigen Kabels und damit eine sichere Kontaktierung gewährleisten.In a further advantageous embodiment of the electrical connection arrangement, the upper part with the lower part or each upper segment with the lower part in the joining position can be locked, in particular by the upper part or the upper part segment associated locking elements, which can be brought into engagement with corresponding Rastelementausnehmungen in the lower part of the terminal arrangement Particularly preferably, the latching element and the Rastelementausnehmung are configured so that they act as a guide during assembly of the lower part and the upper part or the lower part and the upper part segment and so an exact positioning of the first contact means relative to the fixed in the fastening means of the lower part of the device side Cable and thus ensure a secure contact.

Im folgenden wird die erfindungsgemäße elektrische Anordnung anhand mehrerer bevorzugter Ausführungsbeispiele zum Anschluß eines Elektromotors beschrieben. Genausogut könnte die Erfindung auch anhand anderer Verwendungen zum Anschluß anderer elektrischer Geräte beschrieben werden; die erfindungsgemäße elektrische Anschlußanordnung ist vollkommen unabhängig von dem speziellen Anwendungsfall und der Funktion des elektrischen Geräts, das mit der elektrischen Anschlußanordnung kontaktiert wird.In the following, the electrical arrangement according to the invention will be described with reference to several preferred embodiments for connecting an electric motor. The invention could just as well be based on other uses be described for connecting other electrical equipment; the electrical connection arrangement according to the invention is completely independent of the specific application and the function of the electrical device which is contacted with the electrical connection arrangement.

Fig. 1 zeigt in Explosionsdarstellung anhand eines bevorzugten Ausführungsbeispiels die wesentlichen Bestandteile der erfindungsgemäßen Anschlußanordnung, aufweisend ein Unterteil 1, das der Aufnahme eines geräteseitigen Kabels 2 dient, ein Oberteil 3 zur Aufnahme eines - hier nicht dargestellten - anschlußseitigen Kabels und einen Kontaktkörper 4, durch den eine elektrische Verbindung zwischen dem geräteseitigen Kabel 2 und dem anschlußseitigen Kabel hergestellt wird. In dem Unterteil 1 sind ferner Befestigungsmittel 5 ausgebildet, mit denen das geräteseitige Kabel 2 an bzw. in dem Unterteil 1 fixiert werden kann. Die Befestigung des geräteseitigen Kabels 2 in dem Unterteil 1 mit Hilfe der Befestigungsmittel 5 erfolgt dabei ohne elektrische Kontaktierung des geräteseitigen Kabels 2. Fig. 1 shows an exploded view of a preferred embodiment, the essential components of the terminal assembly according to the invention, comprising a lower part 1, which serves to receive a device-side cable 2, an upper part 3 for receiving a - not shown here - connection side cable and a contact body 4, through which an electrical Connection between the device-side cable 2 and the connection-side cable is made. In the lower part 1 fastening means 5 are further formed, with which the device-side cable 2 can be fixed to or in the lower part 1. The attachment of the device-side cable 2 in the lower part 1 by means of the fastening means 5 takes place without electrical contact of the device-side cable. 2

Der Kontaktkörper 4 ist dem Oberteil 3 zugeordnet und in dem Oberteil 3 in seiner Einbauposition funktionsgerecht fixiert, was in den Fig. 3, 5, 7 und 9 dargestellt ist. Der Kontaktkörper 4 ist dabei so in dem Oberteil 3 angeordnet, daß der Kontaktkörper 4 mit einem ersten Kontaktmittel 6 das in dem Unterteil 1 befestigte geräteseitige Kabel 2 in der Fügeposition des Unterteils 1 mit dem Oberteil 3 kontaktiert. Die Fügeposition des Unterteils 1 und des Oberteils 3 ist wiederum in den Fig. 3, 5, 7 und 9 dargestellt. Der Kontaktkörper 4 weist ein zweites Kontaktmittel 7, 8 auf, über das das anschlußseitige Kabel mit dem Kontaktkörper 4 elektrisch verbindbar und an dem Kontaktkörper 4 mechanisch ausreichend befestigbar ist, so daß der elektrische Anschluß auch unter Wirkung bestimmter Auszugkräfte auf das anschlußseitige Kabel sichergestellt ist.The contact body 4 is assigned to the upper part 3 and fixed functionally in the upper part 3 in its installation position, which in the Fig. 3 . 5 . 7 and 9 is shown. The contact body 4 is arranged in the upper part 3, that the contact body 4 contacted with a first contact means 6 attached in the lower part 1 device side cable 2 in the joining position of the lower part 1 with the upper part 3. The joining position of the lower part 1 and the upper part 3 is again in the Fig. 3 . 5 . 7 and 9 shown. The contact body 4 has a second contact means 7, 8, via which the connection-side cable to the contact body 4 is electrically connectable and mechanically sufficiently fastened to the contact body 4, so that the electrical connection is ensured even under certain Auszugkräfte on the connection side cable.

In allen dargestellten Ausführungsbeispielen ist das erste Kontaktmittel 6 als Schneidkontakt ausgestaltet. Der besondere Vorteil der Verwendung eines als Schneidkontakt ausgebildeten ersten Kontaktmittels 6 besteht gerade im Zusammenhang mit der erfindungsgemäßen Anschlußanordnung darin, daß das geräteseitige Kabel 2 zur Kontaktierung nicht freigelegt werden muß, so daß auch die Handhabung des geräteseitigen Kabels 2 bei dessen Befestigung am Unterteil 1 der Anschlußanordnung mit den Befestigungsmitteln 5 gefahrlos möglich ist.In all illustrated embodiments, the first contact means 6 is designed as a cutting contact. The particular advantage of using a trained as a cutting contact first contact means 6 is just in connection with the terminal arrangement according to the invention is that the device-side cable 2 must not be exposed for contacting, so that the handling of the device-side cable 2 in its attachment to the Lower part 1 of the connection arrangement with the fastening means 5 is safely possible.

Das zweite Kontaktmittel 7, 8 des Kontaktkörpers 4 kann grundsätzlich in beliebiger Weise ausgestaltet sein. Dargestellt sind in den Fig. 1 und 5 bis 10 jeweils Ausführungsbeispiele unter Verwendung von Federkraftklemmen 7 und in den Fig. 3 und 4 ein Ausführungsbeispiel unter Verwendung einer Schraubklemme 8 als zweites Kontaktmittel. Die erfindungsgemäße elektrische Anschlußanordnung ist jedoch nicht auf diese Varianten beschränkt, sondern es können auch andere Anschlußtechniken verwendet werden.The second contact means 7, 8 of the contact body 4 can in principle be configured in any desired manner. Shown in the Fig. 1 and 5 to 10 each embodiments using spring clamps 7 and in the Fig. 3 and 4 an embodiment using a screw 8 as a second contact means. However, the electrical connection arrangement according to the invention is not limited to these variants, but other connection techniques can be used.

In den Fig. 1 und 5 bis 10 sind die Federkraftklemmen 7 in bekannter Weise als schlaufenförmig gebogenen Zugfedern ausgestaltet, mit einem Anlageschenkel 9 zur Anlage an einer Stromschiene 10 und mit einem Federschenkel 11, dessen freies Ende in Richtung Anlageschenkel 9 abgewinkelt ist, wobei das freie Ende des Anlageschenkels 9 eine Öffnung im Federschenkel 11 beweglich durchdringt. Die Fig. 1, 5, 6, 9 und 10 zeigen Ausführungsbeispiele, bei denen der Federschenkel 11 der Federkraftklemmen 7 der Einsteckrichtung des anschlußseitigen Kabels zugewandt ist. In den Figuren ist die Federkraftklemme jeweils in ihrer ausgelenkten, geöffneten Position dargestellt, die durch äußere Kraftwirkung hervorgerufen werden kann, beispielsweise durch Betätigen der Federkraftklemme 7 mit einem Betätigungswerkzeug. Das Betätigungswerkzeug wird dabei in gewohnter Weise über eine Betätigungsöffnung im Oberteil 3 der Anschlußanordnung an die Federkraftklemme 7 herangeführt.In the Fig. 1 and 5 to 10 are the spring terminals 7 in a known manner designed as a loop-shaped tension springs, with a plant leg 9 for contact with a busbar 10 and a spring leg 11, the free end is angled towards the plant leg 9, wherein the free end of the abutment leg 9 an opening in the spring leg 11 mobile penetrates. The Fig. 1 . 5 . 6 . 9 and 10 show exemplary embodiments in which the spring leg 11 of the spring-loaded terminals 7 faces the insertion direction of the connection-side cable. In the figures, the spring terminal is shown in each case in its deflected, open position, which can be caused by external force, for example by pressing the spring terminal 7 with an operating tool. The operating tool is thereby brought in the usual way via an actuating opening in the upper part 3 of the terminal assembly to the spring terminal 7.

In einem anderen Ausführungsbeispiel gemäß den Fig. 7 und 8 ist die schlaufenförmig gebogene Federkraftklemme 7 mit ihrem Federschenkel 11 von der Einsteckrichtung des anschlußseitigen Kabels abgewandt in dem Oberteil 3 der Anschlußanordnung angeordnet. Das Funktionsprinzip ist vergleichbar dem der zuvor beschriebenen Federkraftklemmen 7, jedoch gestattet die Ausgestaltung der Federkraftklemme 7 gemäß den Fig. 7 und 8 eine kompaktere Bauweise des Oberteils 3 als es bei den zuvor beschriebenen Ausführungsbeispielen möglich ist.In another embodiment according to the Fig. 7 and 8th the loop-shaped bent spring terminal 7 is arranged with its spring leg 11 facing away from the insertion direction of the connection-side cable in the upper part 3 of the connection arrangement. The operating principle is similar to that of the spring-loaded terminals 7 described above, but allows the design of the spring-loaded terminal 7 according to the Fig. 7 and 8th a more compact design of the upper part 3 than is possible in the embodiments described above.

Bei anderen hier nicht dargestellten Ausführungsbeispielen ist die Federkraftklemme als U-förmig gebogene Sperrhaken-Feder ausgestaltet, bei der der festzuklemmende Leiter durch das freie Ende eines Federschenkels gegen eine Stromschiene gedrückt wird und den Leiter in Auszugrichtung sperrt.In other embodiments not shown here, the spring clamp is designed as a U-shaped pawl spring in which the festzuklemmende conductor is pressed by the free end of a spring leg against a busbar and locks the conductor in the extension direction.

Bei dem Ausführungsbeispiel gemäß den Fig. 9 und 10 ist der Kontaktkörper 4 nicht im wesentlichen geradlinig gestreckt wie bei den anderen dargestellten Ausführungsbeispielen, sondern der Anlageschenkel 9 der Federkraftklemme 7 und die Stromschiene 10 sind gegenüber dem ersten Kontaktmittel 6 im wesentlichen rechtwinklig abgewinkelt angeordnet, wodurch eine insgesamt flachere Bauweise - gemessen von der Unterseite 1 der Anschlußanordnung-erzielt wird.In the embodiment according to the Fig. 9 and 10 is the contact body 4 is not substantially rectilinearly stretched as in the other illustrated embodiments, but the plant leg 9 of the spring terminal 7 and the busbar 10 are arranged at right angles to the first contact means 6 at right angles, creating a flatter overall construction - measured from the bottom. 1 the connection arrangement is achieved.

Bei allen dargestellten Ausführungsbeispielen ist der Kontaktkörper 4 stets so ausgebildet, daß er einen Schenkel einer Steckbrücke 12 aufnehmen kann. Dazu ist der Kontaktkörper 4 in den Ausführungsbeispielen gemäß den Fig. 1 6 und 10 jeweils so ausgebildet, daß an ihn ein Kontaktschenkel 14 angeformt ist, der eine Öffnung zur Aufnahme eines vorzugsweise elastisch oder konisch ausgeformten Schenkels einer Steckbrücke 12 dient. Bei dem Ausführungsbeispiel gemäß den Fig. 3 und 4 ist der Kontaktschenkel 14 nicht an den Kontaktkörper 4 angeformt, sondern in die Schraubklemme 8 des Kontaktkörpers 4 eingeführt, wobei ein sicherer Kontakt zwischen der Schraubklemme 8, der Stromschiene 10 und dem Kontaktschenkel 14 durch Festziehen der Schraubklemme 8 hergestellt wird.In all the illustrated embodiments, the contact body 4 is always formed so that it can receive a leg of a jumper 12. For this purpose, the contact body 4 in the embodiments according to the Fig. 1 6 and 10 each formed so that a contact leg 14 is formed on it, which serves an opening for receiving a preferably elastically or conically shaped leg of a jumper 12. In the embodiment according to the Fig. 3 and 4 the contact leg 14 is not formed on the contact body 4, but introduced into the screw 8 of the contact body 4, wherein a secure contact between the screw 8, the busbar 10 and the contact leg 14 is made by tightening the screw 8.

Besonders vorteilhaft ist in diesem Zusammenhang das Ausführungsbeispiel nach den Fig. 7 und 8. Durch die besondere Orientierung der Federkraftklemme 7 in bezug auf die Einführrichtung des anschlußseitigen Kabels ist es möglich, daß der Schenkel der Steckbrücke 12 zwischen den Anlageschenkel 9 und die Stromschiene 10 eingesteckt werden kann, so daß keine weiteren konstruktiven Maßnahmen notwendig sind, um einen elektrischen Kontakt zwischen dem Kontaktkörper 4 und dem Schenkel der Steckbrücke 12 herzustellen.Particularly advantageous in this context is the embodiment according to the Fig. 7 and 8th , Due to the particular orientation of the spring terminal 7 with respect to the insertion of the connection-side cable, it is possible that the leg of the jumper 12 between the plant leg 9 and the bus bar 10 can be inserted so that no further design measures are necessary to make an electrical contact make between the contact body 4 and the leg of the jumper 12.

Wie in den Fig. 1, 3, 5 und 9 dargestellt, ist zur Aufnahme der Steckbrücke 12 eine Ausnehmung 13 in dem Oberteil 3 der Anschlußanordnung ausgebildet ist. Zum einen wird dadurch die Gefahr des ungewollten elektrischen Kontakts mit den leitenden Teilen der Steckbrücke 12 vermindert bzw. ausgeschlossen und zum anderen wird dadurch die Gefahr einer versehentlichen Entfernung der Steckbrücke 12 aus dem Oberteil 3 der Anschlußanordnung minimiert.As in the Fig. 1 . 3 . 5 and 9 shown, a recess 13 is formed in the upper part 3 of the terminal assembly for receiving the jumper 12 is. On the one hand, this reduces or eliminates the risk of unwanted electrical contact with the conductive parts of the jumper 12 and, on the other hand, minimizes the risk of accidental removal of the jumper 12 from the upper part 3 of the terminal arrangement.

Die Figuren 2a und 2b stellen das Unterteil 1 der Anschlußanordnung separat dar. Das der Fixierung des geräteseitigen Kabels 2 dienende Befestigungsmittel 5 im Unterteil 1 ist hier jeweils als ein Paar von Klammern ausgebildet. In dem dargestellten Ausführungsbeispiel ist das Befestigungsmittel 5 in dem Unterteil 1 ausgeformt und besteht insofern aus dem gleichen isolierfähigen Material wie das gesamte Unterteil 1. Eine besonders gute Befestigung des geräteseitigen Kabels 2 durch das Befestigungsmittel 5 wird dann erreicht, wenn das Unterteil 1 im Bereich der Kabelaufnahme muldenartig ausgeformt ist, so daß das geräteseitige Kabel 2 nicht nur flach auf dem Unterteil 1 aufliegt, sondern zumindest bereichsweise von dem Unterteil 1 umfangen wird. In den dargestellten Ausführungsbeispielen sind die als Klammer ausgebildeten Befestigungsmittel 5 derart elastisch, daß das von ihnen zu fixierende geräteseitige Kabel 2 werkzeuglos in das Befestigungsmittel 5 eingedrückt werden kann.The FIGS. 2a and 2b represent the lower part 1 of the terminal assembly separately. The fixing of the device-side cable 2 serving fastening means 5 in the lower part 1 is here each formed as a pair of brackets. In the illustrated embodiment, the fastening means 5 is formed in the lower part 1 and insofar consists of the same isolierfähigen material as the entire lower part 1. A particularly good attachment of the device-side cable 2 by the fastener 5 is achieved when the lower part 1 in the region of Cable receptacle is formed trough-like, so that the device-side cable 2 not only flat on the lower part 1 rests, but at least partially surrounded by the lower part 1. In the illustrated embodiments, the fastening means 5 designed as a clamp are so elastic that the device-side cable 2 to be fixed by them can be pressed into the fastening means 5 without tools.
