Diese Aufgabe wird mit einer Anschlussleiste nach Anspruch 1 gelöst, welche sich neben den eingangs genannten Merkmalen dadurch auszeichnet, dass jeder Federklemmadapter ferner ein Anschlusselement zur Herstellung einer lösbaren Verbindung mit einem hierzu korrespondierenden Anschlusselement der Elektronik aufweist und dass das Gehäuse zu jedem Federklemmadapter einen zweiten Durchbruch aufweist, durch welchen das entsprechend angeordnete Anschlusselement des Federklemmadapters zugänglich ist, wobei die Federklemmadapter und das Gehäuse derart gestaltet sind, dass die die Anschlusselemente zugänglich machenden zweiten Durchbrüche in wenigstens zwei Reihen alternierend versetzt angeordnet sind.This object is achieved with a terminal block according to claim 1, which in addition to the features mentioned above is characterized in that each spring terminal adapter further comprises a connection element for producing a detachable connection with a corresponding thereto connection element of the electronics and that the housing for each spring terminal adapter a second breakthrough has, through which the correspondingly arranged connection element of the spring clamp adapter is accessible, wherein the spring clamp adapter and the housing are designed such that the terminal elements making accessible second openings are arranged alternately offset in at least two rows.

Mit der vorliegenden Erfindung wird ermöglicht, dass die erfindungsgemäße Anschlussleiste bzw. die darin verbauten Federklemmadapter durch entsprechende (zweite) Durchbrüche des Gehäuses hindurch mit geeigneten Anschlusselementen einer (zur Anschlussleiste externen und ggfs. in einem separaten Gehäuse angeordneten) Elektronik verbindbar sind, wobei hierzu selbstverständlich elektronikseitig für jedes Anschlusselement des Federklemmadapters der Anschlussleiste ein hierzu in Gestaltung und Anordnung korrespondierendes Anschlusselement vorgesehen sein muss bzw. sollte. Aufgrund der erfindungsgemäß vorgesehenen alternierenden Anordnung der die Anschlusselemente freigebenden Durchbrüche in wenigstens zwei Reihen kann dabei unter gleichzeitiger Einhaltung der aus Sicherheitsgründen erforderlichen Mindestabstände zwischen je zwei benachbarten Anschlüssen eine besonders kompakte Bauform der Anschlussleiste sichergestellt werden. Die alternierende Anordnung der Durchbrüche erlaubt nämlich größere Abstände der je zwei benachbarten Federklemmadaptern zugeordneten (zweiten) Durchbrüche, als dies bei bloßer linearer Aneinanderreihung der jeweiligen Durchbrüche in einer Reihe gewährleistet wäre.With the present invention it is possible that the terminal block according to the invention or built therein spring terminal adapter by appropriate (second) openings of the housing through with suitable connection elements of a (external to the terminal block and possibly. In a separate housing arranged) electronics are connected, of course On the electronics side for each connection element of the spring terminal adapter of the terminal block, a connection element corresponding thereto in design and arrangement must or should be provided. Due to the inventively provided alternating arrangement of the connection elements releasing openings in at least two rows can thereby be ensured while maintaining the required safety reasons minimum distances between each two adjacent terminals a particularly compact design of the terminal block. The alternating arrangement of the apertures allows namely greater distances of each two adjacent spring clamp adapters associated (second) breakthroughs, as would be ensured by merely linear juxtaposition of the respective apertures in a row.

Somit kann im Rahmen der Erfindung - selbst bei sehr eng innerhalb des Gehäuses der Anschlussleiste benachbarten Federklemmadaptern - zum Zwecke der Herstellung der Verbindung zwischen den einzelnen Anschlusselementen der Federklemmadapter und der Elektronik auf besonders einfach und kostengünstig herstellbare Steckverbindungen (z.B. mittels nicht isolierter Flachstecker bzw. Messerkontakte und diese aufnehmende Buchsen bzw. Klemmen) zurückgegriffen werden, die einfach durch die entsprechenden Gehäusedurchbrüche hindurch kontaktiert werden können. Die hierfür erforderlichen Mindestabstände (Luftstrecken und Kriechstrecken) können dabei selbst unter gleichzeitiger Realisierung einer besonders kompakten Bauform der Anschlussleiste auf einfache Weise realisiert werden.Thus, in the context of the invention - even with very close within the housing of the terminal block spring terminal adapters - for the purpose of establishing the connection between the individual connection elements of the spring terminal adapter and the electronics on particularly simple and inexpensive to produce connectors (For example, by means of non-insulated tabs or blade contacts and these female receptacles or terminals) can be used, which can be contacted easily through the corresponding housing openings therethrough. The minimum distances required for this purpose (clearances and creepage distances) can be realized in a simple manner, even with the simultaneous realization of a particularly compact design of the connection strip.

In einer ersten bevorzugten Weiterbildung der vorliegenden Erfindung kann vorgesehen sein, dass die zur Durchführung eines gegen die Kontaktfläche zu klemmenden Drahtes vorgesehenen ersten Durchbrüche im Gehäuse der Anschlussleiste in einer Reihe nebeneinander angeordnet sind. Denn für die lediglich endseitig abisolierten Drähte sind wegen der in der Regel außerhalb der Anschlussleiste gegebenen Isolierung des anzuschließenden Drahts bzw. Kabels geringere Abstände durchaus tolerabel. Dass dabei für die ersten Durchbrüche des Gehäuses der Anschlussleiste nicht auch eine alternierende Anordnung vorgesehen ist, erweist sich letztlich im Hinblick auf eine besonders einfache Gestaltung der Federklemmadapter als vorteilhaft, ist jedoch nicht zwingend. Denn vielmehr könnte im Rahmen der vorliegenden Erfindung auch für die ersten Gehäusedurchbrüche eine entsprechend alternierende Anordnung in zwei (oder mehr) Reihen vorgesehen sein.In a first preferred development of the present invention, it can be provided that the first openings provided in the housing of the connection strip for carrying out a wire to be clamped against the contact surface are arranged next to one another in a row. Because for the only end stripped wires smaller distances are quite tolerable because of the given usually outside the terminal strip insulation of the wire or cable to be connected. That for the first openings of the housing of the terminal block is not provided an alternating arrangement, ultimately proves to be advantageous in view of a particularly simple design of the spring terminal adapter, but is not mandatory. Rather, in the context of the present invention, a correspondingly alternating arrangement in two (or more) rows could also be provided for the first housing openings.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist vorteilhaft vorgesehen, dass alle Federklemmadapter identisch aufgebaut sind und je zwei benachbarte Federklemmadapter zur Erzielung der alternierenden Anordnung der Anschlusselemente in verschiedenen Orientierungen, vorzugsweise um jeweils 180° verdreht, in das Gehäuse eingesetzt sind. Dies erleichtert maßgeblich die Herstellung erfindungsgemäßer Anschlussleisten, da somit keine bauartverschiedenen, sondern ausschließlich bauartidentische Federklemmadapter Verwendung finden können.In a further preferred embodiment of the invention, it is advantageously provided that all spring clamp adapters are constructed identically and each two adjacent spring clamp adapters are inserted into the housing in order to achieve the alternating arrangement of the connecting elements in different orientations, preferably by 180 ° in each case. This significantly facilitates the production of terminal strips according to the invention, since thus no design-different, but only design identical spring terminal adapter can be used.

Hierfür ist es von besonderem Vorteil, wenn die Federklemmadapter derart symmetrisch ausgebildet sind, dass sie sich zur Klemmung eines abisolierten Drahtes von zwei gegenüberliegenden Seiten des Federklemmadapters eignen. Denn dadurch wird sichergestellt, dass ein und derselbe Federklemmadapter in zwei verschiedenen Orientierungen in das Gehäuse der Anschlussleiste einsetzbar ist, dabei jedoch stets einen durch den ersten ihm zugeordneten Gehäusedurchbruch hindurchgeführten Draht gegen eine geeignete Kontaktfläche klemmen kann.For this purpose, it is of particular advantage if the spring terminal adapters are formed so symmetrical that they are suitable for clamping a stripped wire from two opposite sides of the spring terminal adapter. Because this ensures that one and the same spring terminal adapter can be inserted in two different orientations in the housing of the terminal block, but it can always clamp a passed through the first associated housing breakthrough wire against a suitable contact surface.

Bei einem entsprechend symmetrisch ausgestalteten Federklemmadapter mit der Möglichkeit zum Klemmanschluss eines (endseitig abisolierten) Drahts von zwei verschiedenen Seiten könnte im Übrigen auch vorgesehen sein, dass das Gehäuse hierfür auf verschiedenen Seiten je einen Durchbruch zur Durchführung eines an den Federklemmadapter anzuschließenden Drahts aufweist, wodurch sich die Herstellung einer elektrischen T-Verbindung zwischen der (an das Anschlusselement des Federklemmadapters angeschlossenen) Elektronik einerseits und zwei (von gegenüberliegenden Seiten) an den Federklemmadapter angeschlossenen Drähten andererseits ergibt, sofern eine solche gewünscht ist. Dies ist jedoch keinesfalls zwingend.In a correspondingly symmetrically designed spring clamp adapter with the possibility for terminal connection of a (end stripped) wire from two different sides could also be provided that the housing for this purpose on each side each have a breakthrough for performing a to be connected to the spring clamp adapter wire, thereby the production of an electrical T-connection between the (connected to the terminal of the spring terminal adapter) electronics on the one hand and two (from opposite sides) connected to the spring terminal adapter wires on the other hand, if such is desired. However, this is by no means mandatory.

Weiterhin ist- bei entsprechend symmetrischer Gestaltung der Federklemmadapter - vorteilhaft vorgesehen, dass das (zum Anschluss der Elektronik dienende) Anschlusselement in Bezug auf die längliche Erstreckung des Federklemmadapters zwischen den zur Klemmung eines Drahts geeigneten gegenüberliegenden Seiten außermittig an diesem angeordnet ist. Hierdurch wird - wenn dann je zwei benachbarte Federklemmadapter um 180° zueinander verdreht in das Gehäuse der Anschlussleiste eingesetzt werden - die alternierende Anordnung der Anschlusselemente und der ihnen zugeordneten zweiten Gehäusedurchbrüche möglich, wobei der Abstand der Anschlusselemente zweier benachbarter Federklemmadapter umso größer ist, je weiter die Anschlusselemente von der Mitte des Federklemmadapters entfernt angeordnet sind.Furthermore, with a correspondingly symmetrical design of the spring clamp adapter, it is advantageously provided that the connection element (serving to connect the electronics) is arranged eccentrically therewith in relation to the elongated extent of the spring clamp adapter between the opposite sides suitable for clamping a wire. In this way - if then two adjacent spring clamp adapter rotated by 180 ° to each other in the housing of the terminal block are used - the alternating arrangement of the connecting elements and their associated second Gehäusedurchbrüche possible, the distance between the connecting elements of two adjacent spring clamp adapter is greater, the farther the Connection elements are located away from the center of the spring clamp adapter.

Eine besonders zweckmäßige Ausgestaltung der erfindungsgemäßen Anschlussleiste bzw. der darin verbauten Federklemmadapter sieht vor, dass jeder Federklemmadapter wenigstens (oder bevorzugt genau) zwei Teile, nämlich ein Federelement und einen Grundkörper, aufweist, wobei der Grundkörper wenigstens eine Kontaktfläche zur Klemmung eines abisolierten Drahtes aufweist und wobei das zur Herstellung einer Verbindung mit der Elektronik dienende Anschlusselement am Grundkörper angeordnet oder durch diesen ausgebildet ist. Falls jeder Federklemmadapter, wie dies bereits vorstehend als vorteilhaft erörtert wurde, von zwei gegenüberliegenden Seiten zur Klemmung eines Drahts geeignet gestaltet sein soll, so muss dann der Grundkörper entsprechend auf beiden Seiten eine entsprechende Kontaktfläche aufweisen bzw. ausbilden. Ferner sollte dann entweder ein einziges Federelement zur Klemmung eines von verschiedenen Seiten eingesteckten Drahts gegen die jeweilige Kontaktfläche geeignet sein, wobei alternativ hierzu selbstverständlich auch zwei - auf den verschiedenen Seiten des Federklemmadapters vorgesehene - Federelemente vorgesehen sein können.A particularly expedient embodiment of the terminal strip according to the invention or the spring terminal adapter installed therein provides that each spring terminal adapter has at least (or preferably exactly) two parts, namely a spring element and a base body, wherein the base body has at least one contact surface for clamping a stripped wire, and wherein the connecting element serving to establish a connection with the electronics is arranged on the base body or is formed by the same. If each spring clamp adapter, as has already been discussed above, should be designed to be suitable for clamping a wire from two opposite sides, then the base body must accordingly have or form a corresponding contact surface on both sides. Furthermore, then either a single spring element should be suitable for clamping a wire inserted from different sides against the respective contact surface, alternatively, of course, two - provided on the different sides of the spring clamp adapter - spring elements can be provided.

In besonders bevorzugter Weise kann dabei im Rahmen der vorliegenden Erfindung vorgesehen sein, dass das (wenigstens eine) Federelement unter Vorspannung stehend in den Grundkörper eingesetzt, jedoch nicht mit diesem verbunden ist. Hierdurch wird wiederum eine besonders einfache und günstige Herstellung und Montage der erfindungsgemäßen Anschlussleiste ermöglicht, da somit auf die Herstellung einer separaten Befestigung der Feder durch Schweißen, Nieten, Schrauben oder Ähnliches verzichtet werden kann.In a particularly preferred manner can be provided in the context of the present invention that the (at least one) spring element is used under bias standing in the body, but not connected to this. As a result, in turn, a particularly simple and inexpensive production and assembly of the terminal block according to the invention is made possible, since thus can be dispensed with the production of a separate attachment of the spring by welding, riveting, screws or the like.

In einer abermals bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass das an dem Federklemmadapter vorgesehene Anschlusselement eine Klemme mit im Wesentlichen U-förmigem Profil ist, in welche durch den ihr zugeordneten Durchbruch des Gehäuses hindurch ein Flachstecker lösbar eingesteckt werden kann. Diese U-Klemme kann ggfs. einteilig mit dem Grundkörpers ausgebildet sein, der in einer besonders bevorzugten Weise (inkl. der daran ausgebildeten U-Klemme) aus einem einzigen flachen Blechzuschnitt hergestellt werden kann, wie dies weiter unten anhand der Zeichnung noch näher erläutert wird.In a again preferred embodiment of the invention, it is provided that the connection element provided on the spring clamp adapter is a clamp with a substantially U-shaped profile into which a flat plug can be detachably inserted through the aperture of the housing assigned to it. This U-clamp may optionally be integrally formed with the base body, which can be made in a particularly preferred manner (including the U-clamp formed thereon) from a single flat sheet metal blank, as will be explained in more detail below with reference to the drawing ,

Ferner ist im Rahmen der vorliegenden Erfindung vorteilhaft vorgesehen, dass die Federklemmadapter innerhalb des Gehäuses durch isolierende Trennwände (z.B. aus Kunststoff) voneinander getrennt sind. Vorteilhaft kann dann - bei geeignet zweiteiliger Gestaltung des Gehäuses der Anschlussleiste - gewährleistet werden, dass die einzelnen Federklemmadapter auf besonders einfache Weise einfach von oben in durch die Trennwände begrenzte Aufnahmen einsetzbar sind, wobei ggfs. auch der Bodenbereich des die Federklemmadapter aufnehmenden Gehäuses der Anschlussleiste so gestaltet sein kann, dass die Federklemmadapter beim Einsetzten von oben automatisch in ihrer richtigen Lage zentriert bzw. stets lagerichtig gehalten werden, was z.B. durch geeignete Schrägen, Anschläge etc. sichergestellt werden kann.Furthermore, it is advantageously provided in the context of the present invention that the spring terminal adapters within the housing by insulating partitions (eg made of plastic) are separated from each other. Advantageously then - with a suitable two-part design of the housing of the terminal block - be ensured that the individual spring clamp adapter in a particularly simple manner from above in the limited by the partitions receptacles are used, where appropriate. Also the bottom portion of the spring terminal adapter housing receiving the terminal block so It can be designed that the spring clamp adapter when inserted from above automatically centered in their correct position and always kept in the correct position, which can be ensured, for example, by appropriate bevels, stops, etc.

Weiterhin umfasst die vorliegende Erfindung in bevorzugter Weise ein elektrisches Steuersystem, welches einen an einer Montageschiene (z.B. an einer Hutschiene bzw. einem DIN-Rail) anbaubaren Basiskörper und einen die Elektronik des Steuersystems beinhaltenden Aufsteckkörper aufweist, wobei basiskörperseitig eine erfindungsgemäße Anschlussleiste der vorstehend beschriebenen Art ausgebildet ist und wobei aufsteckkörperseitig eine Mehrzahl an mit der Elektronik verbundenen Anschlusselementen vorgesehen ist, die derart angeordnet und ausgestaltet sind, dass sie mit den basiskörperseitig durch die jeweils zweiten Durchbrüche des Gehäuses der Anschlussleiste zugänglichen Anschlusselementen der Federklemmadapter eine Steckverbindung herstellen können.Furthermore, the present invention preferably comprises an electrical control system which has a base body which can be attached to a mounting rail (for example on a top hat rail or a DIN rail) and a plug-in body containing the electronics of the control system, wherein the base body side is a terminal block according to the invention of the type described above is formed and wherein on the plug body side is provided a plurality of connection elements connected to the electronics, which are arranged and configured so that they can make a plug connection with the base body side accessible through the respective second openings of the housing of the terminal block connection elements of the spring terminal adapter.

Dabei dienen die durch die Federklemmadapter (mit den zugeordneten ersten Durchbrüchen des Gehäuses der Anschlussleiste) vorteilhaft realisierten Push-In Klemmen dem Anschluss verschiedener endseitig abisolierter Drähte, die zu Aktoren und/oder Sensoren (oder sonstigen Geräten) führen, die dann ihrerseits mittels der - aufsteckkörperseitig verbauten - Elektronik des Steuersystems angesteuert und/oder ausgelesen werden können. Selbstverständlich ist hierbei von Vorteil, wenn über die Basiskörper - unter Verwendung sonstiger z.B. ebenfalls als Steckverbinder ausgeführter Verbindungselemente zwischen Basis- und Aufsteckkörper - auch die Stromversorgung der Elektronik sowie ggfs. eine Anbindung der Elektronik an ein (Feld-) Bussystem erfolgt.The push-in terminals advantageously realized by the spring clamp adapters (with the associated first openings of the housing of the terminal block) serve the connection of various end stripped wires leading to actuators and / or sensors (or other devices), which then in turn by means of - plug-in body side mounted - electronics of the control system can be controlled and / or read. Of course, in this case is advantageous if on the base body - using other, for example, also designed as a connector connecting elements between base and Aufsteckkörper - also the power of the electronics and possibly. A connection of the electronics to a (field) bus system.

Selbstverständlich kann bei einem solchen System das Gehäuse der Anschlussleiste gleichzeitig auch einen Gehäuseteil des Basiskörpers darstellen.Of course, in such a system, the housing of the terminal block simultaneously represent a housing part of the base body.

Außerdem betrifft die Erfindung in nochmals bevorzugter Weiterbildung eines solchen Steuersystems eine Systemgestaltung, bei der der Aufsteckkörper zum Zwecke des Herstellens und Lösens der Steckverbindungen um eine parallel zu den durch die zweiten Durchbrüche gebildeten Reihen verlaufende Achse derart schwenkbar an dem Basiskörper gelagert ist, dass während eines solchen Schwenkvorgangs die Steckverbindungen der zueinander korrespondierenden Anschlusselemente, die in verschiedenen Reihen angeordnet sind, nacheinander hergestellt bzw. gelöst werden.Moreover, the invention in a further preferred embodiment of such a control system relates to a system design in which the plug-on body is mounted for the purpose of producing and releasing the connectors about a parallel to the rows formed by the second rows extending axis pivotally mounted on the base body that during a Such pivoting operation, the connectors of the mutually corresponding connection elements, which are arranged in different rows, successively manufactured or solved.

Die im vorstehend genannten Sinne durch eine Schwenkbewegung erfolgende Herstellung der Steckverbindung zwischen allen basiskörperseitigen (d.h. anschlussleistenseitigen) Anschlusselementen der Federklemmadapter und den hierzu korrespondierenden aufsteckkörperseitigen Anschlusselementen der Elektronik nutzt dabei ebenfalls die in mehreren Reihen gegebene Anordnung der einzelnen Anschlusselemente aus, indem sich hierdurch die Steckverbindungen der in verschiedenen Reihen befindlichen Anschlusselemente sukzessive herstellen bzw. lösen. Hierdurch verringert sich die zum Herstellen bzw. Lösen der Steckverbindungen insgesamt erforderliche Kraft, da nicht alle Steckverbindungen gleichzeitig hergestellt bzw. gelöst werden müssen.The above-mentioned meaning by a pivoting movement producing the connector between all basiskörperseitigen (ie terminal strip side) connection elements of the spring clamp adapter and the corresponding thereto plug-side connector elements of the electronics also exploits the given in several rows arrangement of the individual connection elements by thereby the connectors of successively establish or dissolve connection elements located in different rows. This reduces the total force required to produce or release the connectors, since not all connectors have to be made or released at the same time.

Und schließlich betrifft die vorliegende Erfindung nicht nur eine Anschlussleiste bzw. ein System der vorstehend beschriebenen Art, sondern auch einen zum Einbau in solche Anschlussleisten geeigneten Federklemmadapter. Der erfindungsgemäße Federklemmadapter umfasst wenigstens ein Federelement, welches von zwei gegenüberliegenden Seiten zur Klemmung eines endseitig abisolierten Drahtes gegen eine (vorteilhaft durch den Federklemmadapter ausgebildete) Kontaktfläche geeignet ist, und ein Anschlusselement zur Herstellung einer Verbindung mit einem hierzu korrespondierenden Anschlusselement einer Elektronik, wobei das Anschlusselement in Bezug auf die längliche Erstreckung des Federklemmadapters zwischen den zur Klemmung eines Drahts geeigneten gegenüberliegenden Seiten außermittig an diesem angeordnet ist.Finally, the present invention not only relates to a terminal block or a system of the type described above, but also to a spring terminal adapter suitable for installation in such terminal blocks. The spring clamp adapter according to the invention comprises at least one spring element, which is suitable for clamping a wire stripped endwise against a contact surface (advantageously formed by the spring clamp adapter), and a connection element for establishing a connection to a connection element of an electronics corresponding thereto, wherein the connection element with respect to the elongated extension of the spring clamp adapter between the suitable for clamping a wire opposite sides eccentrically disposed thereon.

Selbstverständlich gelten alle bereits vorstehend in Zusammenhang mit der erfindungsgemäßen Anschlussleiste genannten Aspekte, Vorteile und deren bevorzugte Ausgestaltungen, soweit sich diese auf die darin verbauten Federklemmadapter beziehen, in gleicher Weise für die erfindungsgemäßen Federklemmadapter, so dass insoweit zur Vermeidung von Wiederholungen hierauf verwiesen wird.Of course, all mentioned above in connection with the terminal block according to the invention aspects, advantages and their preferred embodiments, insofar as these relate to the built-in spring clamp adapter apply in the same way for the spring terminal adapter according to the invention, so that reference is made in this respect to avoid repetition thereof.

Erfindungsgemäße Federklemmadapter können in alternierend um jeweils 180° verdrehter Orientierung in das Gehäuse einer erfindungsgemäßen Anschlussleiste eingesetzt werden und erlauben so - bei Verwendung bauartidentischer Federklemmadapter - eine alternierende Anordnung derjenigen Gehäusedurchbrüche, durch die die (außermittig an den verschiedenen Federklemmadaptern angeordneten) Anschlusselemente zugänglich sind, in (genau) zwei Reihen. Somit kann auch bei enger Aneinanderreihung der Federklemmadapter innerhalb des Gehäuses der Anschlussleiste ein ausreichender Abstand (Luft- und Kriechstrecken) zwischen den durch entsprechende Gehäusedurchbrüche erfolgenden Elektronikanschlüssen sichergestellt werden.Inventive spring terminal adapter can be used in alternately rotated by 180 ° orientation in the housing of a terminal block according to the invention Thus, when using design-identical spring clamp adapters, an alternating arrangement of those housing breakthroughs through which the connection elements (arranged off-center at the various spring clamp adapters) are accessible, in (exactly) two rows. Thus, even with close juxtaposition of the spring terminal adapter within the housing of the terminal block a sufficient distance (creepage distances and clearances) can be ensured between taking place through corresponding housing openings electronic connections.

Fig. 1 zeigt ein Ausführungsbeispiel einer erfindungemäßen Anschlussleiste 1 mit einem aus zwei Gehäuseschalen 2a, 2b hergestellten Gehäuse 2 und einer Mehrzahl an innerhalb des Gehäuses 2 in linearer Reihe nebeneinander angeordneten Federklemmadaptern 3, die in ihrer Bauart jeweils identisch und alternierend in um jeweils 180° verdrehten Orientierungen innerhalb des Gehäuses 2 angeordnet sind. Fig. 1 shows an embodiment of a erfindungemäßen terminal block 1 with a housing 2 made of two housing shells 2a, 2b and a plurality of within the housing 2 in a linear row juxtaposed spring terminal adapters 3, each identical in their design and alternately in rotated by 180 ° orientations within of the housing 2 are arranged.

Jeder Federklemmadapter 3, der in den Fig. 3a-3d in verschiedenen Ansichten (Fig. 3a: perspektivische Ansicht; Fig. 3b: Seitenansicht auf Längsseite; Fig. 3c: Seitenansicht auf Querseite; Fig. 3d: Draufsicht) nochmals detailliert dargestellt ist, besteht aus einem Grundkörper 4 und einem darin - ohne feste Verbindung - eingesetzten Federelement 5 mit zwei Federschenkeln 5a, 5b, die endseitig gegen die am Grundkörper 4 ausgebildeten Kontaktflächen 4a bzw. 4b vorgespannt und jeweils derart auslenkbar sind, dass damit ein endseitig abisolierter Draht 6, wie dies in Fig. 1 dargestellt ist, gegen die dem betreffenden Federschenkel 5a, 5b zugeordnete Kontaktfläche 4a, 4b zur Herstellung einer elektrisch leitenden Verbindung mit demselben festgeklemmt werden kann.Each spring clip adapter 3, which in the Fig. 3a-3d in different views ( Fig. 3a : perspective view; Fig. 3b : Side view on the long side; Fig. 3c : Side view on lateral side; Fig. 3d : Plan view) is again detailed, consists of a base body 4 and a therein - without firm connection - inserted spring element 5 with two spring legs 5a, 5b, the end against the formed on the base body 4 contact surfaces 4a and 4b biased and are each such deflected in that with it an end stripped wire 6, as in Fig. 1 is shown, against the respective spring leg 5a, 5b associated contact surface 4a, 4b can be clamped to produce an electrically conductive connection with the same.

Das Gehäuse 2 der Anschlussleiste 1 weist dabei für jeden Federklemmadapter 3 (wenigstens) einen ersten Durchbruch 7 auf, durch welchen ein an den betreffenden Federklemmadapter (durch geeignete Klemmung) anzuschließender Draht 6 hindurchführbar ist. Im vorliegenden Ausführungsbeispiel der Erfindung sind alle ersten Durchbrüche 7 des Gehäuses 2 in einer linearen Reihe R1 (d.h. auf gleicher Höhe des Gehäuses 2) angeordnet, und zwar jeweils derart, dass ein durch den entsprechenden Durchbruch 7 hindurchgeführter Draht 6 direkt zum Kontaktbereich zwischen Federelement 5 (bzw. dessen Federschenkel 5a bzw. 5b) und Kontaktfläche 4a bzw. 4b geführt wird, so dass er beim Einstecken in die solchermaßen realisierte "Push-In Klemme" unter Auslenkung des betreffenden Federschenkels 5a, 5b nach innen schließlich zwischen dem endseitigen Rand des Federschenkels 5a, 5b und der hierzu korrespondierenden Kontaktfläche 4a, 4b mittels einer Keilklemmung gegen ein Herausziehen gesichert ist.The housing 2 of the terminal block 1 has for each spring terminal adapter 3 (at least) on a first opening 7, through which a to the relevant spring terminal adapter (by suitable clamping) to be connected wire 6 can be passed. In the present embodiment of the invention, all first openings 7 of the housing 2 in a linear row R 1 (ie, at the same height of the housing 2) are arranged, in each case such that a guided through the corresponding opening 7 wire 6 directly to the contact area between the spring element 5 (or its spring legs 5a and 5b) and contact surface 4a and 4b is guided, so that when inserting into the thus realized "push-in clamp" under deflection of the relevant spring leg 5a, 5b inwardly finally between the end edge of the spring leg 5a, 5b and the corresponding thereto contact surface 4a, 4b is secured by a wedge clamp against pulling out.

Vorliegend ist jeder Federklemmadapter 3 derart symmetrisch ausgebildet, dass er sich prinzipiell zur Klemmung eines Drahts 6 von zwei gegenüberliegenden Seiten des Federklemmadapters 3 eignet, wenngleich das Gehäuse 2 der Anschlussleiste 1 bzw. die darin für jeden Federklemmadapter 3 vorgesehenen ersten Durchbrüche 7 diesen lediglich von einer Seite zum Anschluss eines Drahts 6 zugänglich machen. Die symmetrische Gestaltung der Federklemmadapter 3 gestattet jedoch, dass je zwei benachbarte Federklemmadapter 3 in zwei verschiedenen, um 180° zueinander verdrehten Orientierungen in das Gehäuse 2 einsetzbar sind, wobei in beiden Orientierungen gewährleistet ist, dass ein durch den dem jeweiligen Federklemmadapter 3 zugeordneten Durchbruch 7 hindurchgeführter Draht 6 entsprechend - entweder durch den in Fig. 3b rechts dargestellten Federschenkel 5a gegen die Kontaktfläche 4a oder durch den in Fig. 3b links dargestellten Federschenkel 5b gegen die Kontaktfläche 4b - klemmbar ist.In the present case, each spring clamp adapter 3 is formed symmetrically such that it is suitable in principle for clamping a wire 6 from two opposite sides of the spring clamp adapter 3, although the housing 2 of the terminal block 1 or provided therein for each spring clamp adapter 3 first breakthroughs 7 this only from one Access side for connecting a wire 6. However, the symmetrical design of the spring clamp adapter 3 allows each two adjacent spring clamp adapter 3 in two different, to Orientations rotated 180 ° to one another can be inserted into the housing 2, wherein it is ensured in both orientations that a wire 6 passed through the aperture 7 associated with the respective spring clamp adapter 3 is replaced either by the in Fig. 3b shown spring leg 5a against the contact surface 4a or through the in Fig. 3b shown spring leg 5b against the contact surface 4b - is clamped.

In vorteilhafter - vorliegend jedoch nicht dargestellter Weise - lässt sich der nicht dem jeweiligen Durchbruch 7 zugewandte (hintere) Klemmmechanismus 4a, 5a bzw. 4b, 5b verschiedener Federklemmadapter 3 jedoch ggfs. selbst dann nutzten, wenn diesem kein hierzu korrespondierender Gehäusedurchbruch zugeordnet ist. So könnte z.B. das Signal eines an einen ersten Federklemmadapter 3 angeschlossenen Drahts 6 innerhalb des Gehäuses 2 auf einen oder mehrere andere Federklemmadapter 3 und somit an den oder die hieran angeschlossenen Drähte verteilt werden, indem innerhalb des Gehäuses 2 eine ggfs. mehrteilige Brücke aus leitfähigen Elementen vorgesehen wird, die verschiedene Federklemmadapter 3 miteinander verbindet und die hierzu an die jeweiligen Federklemmadapter 3 jeweils durch eine Klemmung mittels der hinteren Federschenkel 5a bzw. 5b gegen die ihnen zugeordnete Kontaktfläche 4a bzw. 4b angeschlossen ist. So lässt sich unter Einbau einer entsprechenden Brücke in das Gehäuse 2 auf einfache Weise ein Signal von einem ersten an die Anschlussleiste 1 angeschlossenen Draht 6 auf wenigstens einen weiteren an die Anschlussleiste 1 angeschlossenen Draht 6 verteilen, wenn dies gewünscht ist.In an advantageous - but not shown here way - can not the respective breakthrough 7 facing (rear) clamping mechanism 4a, 5a and 4b, 5b different spring terminal adapter 3, however, if necessary. Even then used, if this is not associated with this corresponding housing breakthrough. Thus, for example, the signal of a wire 6 connected to a first spring clamp adapter 3 could be distributed within the housing 2 to one or more other spring clamp adapters 3 and thus to the wires or wires connected thereto, by a possibly multi-part bridge of conductive elements inside the housing 2 is provided, the various spring terminal adapter 3 connects to each other and this is connected to the respective spring terminal adapter 3 respectively by clamping by means of the rear spring legs 5a and 5b against their associated contact surface 4a and 4b. Thus, by installing a corresponding bridge in the housing 2 in a simple manner, a signal from a first to the terminal block. 1 distribute the connected wire 6 on at least one other connected to the terminal block 1 wire 6, if desired.

Jeder Federklemmadapter 3 weist ein Anschlusselement 8 in Art einer im Wesentlichen U-förmig profilierten Klemme mit gegen Federkraft spreizbaren Schenkeln 8a, 8b auf, welches zum Anschluss einer (externen) Elektronik an den Federklemmadapter 3 dient. Hierbei kann an das Anschlusselement 8 des Federklemmadapters 3, wie dies in Fig. 3c exemplarisch dargestellt ist, unter Herstellung einer einfach wieder lösbaren Steckverbindung ein hierzu korrespondierendes Anschlusselement 9 in Art eines (aus elektrisch leitfähigem Material bestehenden und nicht isolierten) Flachsteckers 9 angeschlossen werden, indem dieser gemäß Pfeil E zwischen die beiden Klemmschenkel 8a, 8b der U-Klemme 8 gesteckt wird. Der Flachstecker 9 wiederum kann z.B. aus einem die Elektronik aufnehmenden Gehäuse (z.B. durch hierzu korrespondierende Gehäusedurchbrüche) hervorstehen und auf geeignete Weise mit einem Ein- und/oder Ausgang der Elektronik verbunden sein. Es versteht sich jedoch von selbst, dass im Rahmen der vorliegenden Erfindung z.B. auch elektronikseitig entsprechende U-Klemmen vorgesehen sein könnten, die von an den Federklemmadaptern geeignet angeordneten Flachsteckern kontaktiert werden. Ferner können im Rahmen der vorliegenden Erfindung ersichtlich auch sonstige Arten von zueinander korrespondierenden Anschlusselementen Verwendung finden, um die einzelnen Federklemmadapter mit der (externen) Elektronik zu verbinden.Each spring terminal adapter 3 has a connection element 8 in the manner of a substantially U-shaped profiled clamp with legs 8a, 8b which can be spread apart by spring force and which serves to connect an (external) electronics to the spring clamp adapter 3. This can be connected to the connection element 8 of the spring clamp adapter 3, as in Fig. 3c is shown as an example, while producing a simply re-releasable connector a corresponding thereto connecting element 9 in the manner of (consisting of electrically conductive material and non-insulated) tab 9 are connected by this according to arrow E between the two clamping legs 8a, 8b of the U-terminal 8 is plugged. The tab 9, in turn, for example, from a housing accommodating the electronics (eg, by corresponding housing openings) protrude and be connected in a suitable manner with an input and / or output of the electronics. However, it goes without saying that in the context of the present invention, for example, corresponding U terminals can be provided on the electronics side, which are contacted by flat plugs suitably arranged on the spring terminal adapters. Furthermore, in the context of the present invention, other types of connecting elements corresponding to one another can be used, as the case may be single spring clamp adapter to the (external) electronics to connect.

Das Gehäuse 2 der Anschlussleiste 1 weist hierfür zu jedem Federklemmadapter 3 einen zweiten Durchbruch 10 auf, durch welchen das Anschlusselement 8 des betreffenden Federklemmadapters 3 (zur Herstellung der gewünschten Verbindung mit einem hierzu korrespondierenden Anschlusselement) zugänglich ist, wobei die Federklemmadapter 3 und das Gehäuse 2 der Anschlussleiste 1 derart gestaltet sind, dass die die Anschlusselemente 8 zugänglich machenden Durchbrüche 10 (sowie die Anschlusselemente 8 selbst) in zwei Reihen R2, R3 alternierend versetzt angeordnet sind. Hierdurch lassen sich - im Vergleich zu einer rein linearen Anordnung der Durchbrüche 10 in einer Reihe - die Abstände zwischen benachbarten Durchbrüchen (bzw. den durch die Durchbrüche 10 hindurch geführten Anschlusselementen 8 bzw. 9) vergrößern, womit sich die aus Sicherheitsgründen einzuhaltenden Kriechstrecken und Luftstrecken selbst bei innerhalb des Gehäuses 2 dicht nebeneinander angeordneten Federklemmadapter 3 einhalten lassen.The housing 2 of the terminal block 1 has for this purpose for each spring terminal adapter 3, a second opening 10, through which the connection element 8 of the respective spring clamp adapter 3 (for producing the desired connection with a corresponding thereto connecting element) is accessible, wherein the spring clamp adapter 3 and the housing. 2 the terminal block 1 are designed such that the terminal elements 8 making access openings 10 (and the connection elements 8 itself) in two rows R 2 , R 3 are arranged alternately offset. This allows - in comparison to a purely linear arrangement of the apertures 10 in a row - the distances between adjacent openings (or through the apertures 10 guided through connecting elements 8 and 9) increase, bringing the creepage distances and clearances to be respected for safety reasons even when inside the housing 2 tightly juxtaposed spring clamp adapter 3 can be maintained.

Eine an die erfindungsgemäße Anschlussleiste 1 anzuschließende Elektronik bzw. ein die Elektronik aufnehmendes Modul (Aufsteckkörper) mit geeigneten Anschlusselementen kann somit vorteilhaft über eine der geometrischen Anordnung der Anschlusselemente 8 (bzw. der Durchbrüche 10 am Gehäuse 2 der Anschlussleiste 1) entsprechende Anordnung an Anschlusselementen (Flachsteckern 9) aufweisen, wodurch vorteilhaft mittels eines einzigen Steckvorgangs eine Verbindung zu allen Anschlusselementen 8 der verschiedenen Federklemmadapter 3 (und letztlich die gewünschte elektrisch leitende Verbindung zwischen den an die Federklemmadapter 3 angeschlossenen Drähten 6 und der Elektronik) herstellbar ist. Zur Verminderung der dabei erforderlichen Kraft, die sich bei gleichzeitig erfolgender Herstellung aller Steckverbindung aus der Summe der zur Herstellung aller einzelnen Steckverbindungen notwendigen Kräfte ergibt, könnte dann vorteilhaft vorgesehen sein, dass ein die zu den Anschlusselementen 8 der Federklemmadapter 3 korrespondierenden Anschlusselemente 9 aufweisendes (Aufsteck-)Modul relativ zur Anschlussleiste 1 verschwenkbar ist, wie dies weiter unten noch in Zusammenhang mit Fig. 4 erläutert wird.An electronics to be connected to the terminal strip 1 according to the invention or a module accommodating the electronics (plug-in body) with suitable connection elements can thus advantageously have an arrangement of connection elements corresponding to the geometrical arrangement of the connection elements 8 (or the openings 10 on the housing 2 of the terminal strip 1). tabs 9), whereby advantageously by means of a single plug connection to all connection elements 8 of the various spring terminal adapter 3 (and ultimately the desired electrically conductive connection between the connected to the spring terminal adapter 3 wires 6 and the electronics) can be produced. To reduce the force required thereby, which results in the simultaneous production of all plug-in connection from the sum of the forces necessary for the production of all individual connectors, then it could be advantageously provided that one of the terminal elements 8 of the spring terminal 3 corresponding terminal elements 9 exhibiting (attachment -) Module is pivotable relative to the terminal block 1, as further below in connection with Fig. 4 is explained.

In Fig. 1 ist außerdem erkennbar, dass eine stets korrekte Positionierung der einzelnen Federklemmadapter 3 innerhalb der hierfür im Gehäuse 2 vorgesehenen Aufnahmen, welche jeweils seitlich durch (isolierende) Trennwände 11 begrenzt sind, auch durch einen sich vom Boden der jeweiligen Aufnahme vertikal erstreckenden Steg 12 gewährleistet wird, welcher durch eine hierzu korrespondierende Öffnung 13 (vgl. Fig. 3b) in der Unterseite des jeweiligen Federklemmadapters 3 hindurchgeführt ist und somit einen Anschlag bildet, der einer Verschiebung des jeweiligen Federklemmadapters 3 in Längsrichtung entgegenwirkt. Ferner sind die die Kontaktflächen 4a, 4b ausbildenden Querstege des Grundkörpers 4 der Federklemmadapter 3 leicht schräg zueinander orientiert und in ihrer Neigung an einen entsprechenden Verlauf des Bodens der Aufnahmen angepasst. Außerdem kann z.B. auch in der oberen Gehäuseschale 2b für jeden Federklemmadapter 3 ein - in Fig. 1 nicht dargestellter - Anschlagszapfen oder Anschlagssteg vorgesehen sein, welcher dem korrekt in das Gehäuse 2 eingesetztem Federklemmadapter 3 oberseitig anliegt und mit welchem der jeweilige Federklemmadapter 3 gegen eine Verschiebung nach oben gesichert wird, was ansonsten z.B. beim Herausziehen eines Steckers 9 aus dem Anschlusselement 8 bei einem nicht anderweitig innerhalb des Gehäuses 2 befestigtem Federklemmadapter 3 in nachteiliger Weise möglich wäre.In Fig. 1 It can also be seen that an always correct positioning of the individual spring terminal adapters 3 within the receptacles 2 provided for this purpose in the housing 2, which are laterally bounded by (insulating) partitions 11, is also ensured by a web 12 extending vertically from the bottom of the respective receptacle. which by a corresponding opening 13 (see. Fig. 3b ) is guided in the bottom of the respective spring clamp adapter 3 and thus forms a stop which counteracts a displacement of the respective spring clamp adapter 3 in the longitudinal direction. Furthermore, the transverse webs of the base body 4 forming the contact surfaces 4a, 4b are the spring clamping adapter 3 slightly inclined to each other oriented and adapted in their inclination to a corresponding course of the bottom of the images. In addition, for example, in the upper housing shell 2b for each spring terminal adapter 3 a - in Fig. 1 not shown - stop pin or stop web be provided, which is the top correctly abuts the inserted into the housing 2 spring terminal 3 and with which the respective spring terminal adapter 3 is secured against displacement upwards, which otherwise eg when pulling out a connector 9 from the connection element 8 at a not otherwise within the housing 2 fixed spring terminal adapter 3 would be possible in a disadvantageous manner.

Schließlich zeigt Fig. 1 noch, dass jedem Federklemmadapter 3 ein weiterer Gehäusedurchbruch 13 zugeordnet ist, durch welchen hindurch mittels eines externen Werkzeugs der einen Draht klemmende Federschenkel 5a, 5b zugänglich ist, um (durch weitere Auslenkung des Federschenkels 5a, 5b nach Innen) die gegebene Keilklemmung des Drahts 6 zu lösen und diesen wieder herausziehen zu können.Finally shows Fig. 1 Still, that each spring terminal adapter 3 is associated with a further housing opening 13, through which by means of an external tool of a wire clamping spring legs 5a, 5b is accessible to (by further deflection of the spring leg 5a, 5b inward) given the wedge clamping of the wire. 6 to solve and to be able to pull this out again.

Fig. 2 zeigt eine Teildarstellung der unteren Gehäusehälfte 2a der Anschlussleiste 1 mit darin eingesetzten Federklemmadaptern 3, um deren in linearer Reihe nebeneinander erfolgende Anordnung in verschiedenen Orientierungen, bei denen wechselweise die verschiedenen Federschenkel 5a, 5b nach vorne weisen, zu veranschaulichen. Ferner ist in Fig. 2 gut erkennbar, dass die Federklemmadapter 3 innerhalb des Gehäuses 2 durch isolierende Trennwände 11 voneinander getrennt sind. Fig. 2 shows a partial view of the lower housing half 2a of the terminal block 1 with spring clamp adapters 3 inserted therein to illustrate their arrangement in a linear row next to each other arrangement in different orientations, in which alternately the different spring legs 5a, 5b point forward. Furthermore, in Fig. 2 clearly seen that the spring terminal adapter 3 are separated from each other within the housing 2 by insulating partitions 11.

Die Fig. 3a - 3d zeigen schließlich noch in verschiedenen vorstehend bereits erläuterten Ansichten ein Ausführungsbeispiel einer erfindungsgemäßen Federklemme 3, wie dieses bereits bei der Anschlussleiste 1 gemäß den Fig. 1 und 2 zur Verwendung kam.The Fig. 3a - 3d Finally, in various views already explained above an embodiment of a spring clip 3 according to the invention, as this already in the terminal block 1 according to the Fig. 1 and 2 came to use.

Der z.B. aus einer Kupferlegierung (beispielsweise CuSn6) herstellbare Grundkörper 4 eines solchen Federklemmadapters 3, welcher einteilig auch das außermittig hieran angeordnete Anschlusselement 8 ausbildet, kann aus einem einzigen Blechzuschnitt hergestellt werden. Hierzu müssen lediglich die die beiden Kontaktflächen 4a, 4b ausbildenden und den Grundkörper 4 nach unten begrenzenden Querstege sowie der als obere Anlagefläche 4c für das Federelement 5 dienende Quersteg 4c (um ca. 90°) geeignet abgekantet werden. Das als U-Klemme ausgestaltete Anschlusselement 8 kann dabei ebenfalls aus demselben Blechzuschnitt geformt werden, weshalb eine seitliche Wand 4d des Grundkörpers 4, welche den oberen Quersteg 4c mit den die Kontaktflächen 4a, 4b bildenden Querstege verbindet, eine entsprechende Aussparung 4e aufweist (vgl. Fig. 3b).The example of a copper alloy (for example, CuSn 6 ) producible base body 4 of such a spring clamp adapter 3, which also integrally forms the eccentrically arranged thereon connecting element 8 can be made from a single sheet metal blank. For this purpose, only the two contact surfaces 4a, 4b forming and the base body 4 downwardly limiting transverse webs and serving as the upper abutment surface 4c for the spring element 5 crosspiece 4c (approximately 90 °) to be bent suitable. The designed as a U-terminal connection element 8 can also be formed from the same sheet metal blank, which is why a side wall 4d of the base 4, which connects the upper crossbar 4c with the contact surfaces 4a, 4b forming transverse webs, a corresponding recess 4e has (see. Fig. 3b ).

Das Federelement 5, welches mit seinen nach innen gerichteten Federschenkeln 5a, 5b von gegenüberliegenden Seiten die Klemmung eines Drahts gegen die jeweilige (durch den Grundkörper 4 ausgebildete) Kontaktfläche 4a, 4b ermöglicht, kann vorzugsweise aus Federstahl hergestellt sein.The spring element 5, which with its inwardly directed spring legs 5a, 5b from opposite sides of the clamping of a wire against the respective (formed by the main body 4) contact surface 4a, 4b, may preferably be made of spring steel.

Die Draufsicht auf den Federklemmadapter 3 aus Fig. 3d zeigt schließlich noch, dass das Anschlusselement 8, bezogen auf die längliche Erstreckung L des Federklemmadapters 3 zwischen den zum Anschluss eines Drahts geeigneten und gegenüberliegenden Seiten, außermittig an dem Federklemmadapter 3 angeordnet ist.The top view of the spring clamp adapter 3 off Fig. 3d shows finally that the connection element 8, relative to the elongated extension L of the spring clamp adapter 3 between the suitable for connecting a wire and opposite sides, is arranged eccentrically on the spring clamp adapter 3.

Die insgesamt sehr kompakte und einfache Bauweise des Federklemmadapters 3 aus Grundkörper 4 und Federelement 5 ermöglicht aufgrund kurzer Verbindungswege eine besonders niederinduktive Verbindung zwischen einem mittels einem Federschenkel geklemmten Draht einerseits und der - über das Anschlusselement 8 anzuschließenden - Elektronik andererseits.The overall very compact and simple design of the spring clamp adapter 3 of the base body 4 and spring element 5 allows due to short connection paths a particularly low-inductive connection between a clamped by a spring leg wire on the one hand and - to be connected via the connection element 8 - electronics on the other.

Fig. 4 zeigt schließlich noch ein Ausführungsbeispiel eines ebenfalls erfindungsgemäßen elektrischen Steuersystems 14, welches in zweiteiliger Ausgestaltung einen Basiskörper 15 und einen Aufsteckkörper 16 aufweist, wobei der mittels geeigneter Befestigungsmittel an eine Hutschiene 17 anbaubare Basiskörper 15 eine erfindungsgemäße Anschlussleiste 1 ausbildet bzw. aufweist. Die Anschlussleiste 1 umfasst, wie bereits das in den Fig. 1 - 3 veranschaulichte Ausführungsbeispiel, ein zweiteiliges Gehäuse 2 aus Gehäuseunterschale 2a und Gehäuseoberschale 2b, in welchen - in einer Reihe angeordnete - erste Durchbrüche 7 zum Anschluss absolierter Drähte an innerhalb des Gehäuses 2 angeordneter Federklemmadapter 3 (vgl. Fig. 3) vorgesehen sind. Durch die unmittelbar darüber angeordnete Reihe von Durchbrüchen 13 kann die innerhalb des Gehäuses 2 erfolgende Klemmung eines Drahts wieder gelöst werden. Ferner ist in dem Gehäuse 2 für jeden darin angeordneten Federklemmadapter 3 jeweils ein zweiter Durchbruch 10 vorgesehen, durch welchen das jeweilige Anschlusselement 8 des betreffenden Federklemmadapters 3 zugänglich ist, wie dies in Fig. 4 erkennbar ist. Die zweiten Durchbrüche 10 im Gehäuse 2 der basiskörperseitig ausgebildeten Anschlussleiste 1 sind, wie gehabt, in zwei Reihen R2, R3 alternierend versetzt zueinander angeordnet. Fig. 4 Finally, shows an embodiment of an electrical control system 14 according to the invention, which has a base body 15 and a plug-in body 16 in two-part design, wherein the base body 15, which can be attached to a DIN rail 17 by means of suitable fastening means, forms or has a connection strip 1 according to the invention. The terminal block 1 comprises, as already in the Fig. 1-3 illustrated embodiment, a two-part housing 2 of housing lower shell 2a and upper housing shell 2b, in which - arranged in a row - First openings 7 for connection of the wires to the arranged inside the housing 2 spring clamp adapter 3 (see. Fig. 3 ) are provided. By means of the directly above arranged row of openings 13, the taking place within the housing 2 clamping of a wire can be solved again. Further, in each case a second opening 10 is provided in the housing 2 for each spring clamp adapter 3 arranged therein through which the respective connection element 8 of the relevant spring clamp adapter 3 is accessible, as shown in FIG Fig. 4 is recognizable. The second openings 10 in the housing 2 of the base body side formed terminal block 1 are, as before, arranged in two rows R 2 , R 3 alternately offset from one another.

Innerhalb des Aufsteckkörpers 16, welcher um eine Achse S schwenkbar an dem Basiskörper 15 gelagert ist, ist die eigentliche Steuerelektronik (nicht dargestellt) des Steuersystems 14 angeordnet. Die Steuerelektronik ist mit - in Richtung zum Basiskörper 15 weisenden - Anschlusselementen 9 (hier: nicht isolierte Flachstecker) verbunden, die ihrerseits mit den hierzu korrespondierenden Anschlusselementen 8 (hier: U-Klemmen wie in Fig. 3) der einzelnen Federklemmen 3 unter Herstellung einer Steckverbindung verbindbar sind und hierzu korrespondierend - d.h. ebenfalls in zwei Reihen - an dem Aufsteckkörper 16 angeordnet sind bzw. durch dessen Gehäuse hindurch in Richtung zum Basiskörper 15 hervorstehen. Die in Form von Flachsteckern ausgestalteten aufsteckkörperseitigen Anschlusselemente 9 können z.B. unmittelbar an einer Platine der Elektronik befestigt sein.Within the plug-on body 16, which is mounted pivotably about an axis S on the base body 15, the actual control electronics (not shown) of the control system 14 is arranged. The control electronics is connected to - in the direction of the base body 15 facing - connecting elements 9 (here: non-insulated tabs), which in turn with the corresponding thereto connecting elements 8 (here: U-terminals as in Fig. 3 ) of the individual spring terminals 3 are connected to produce a plug connection and corresponding thereto - ie also in two rows - are arranged on the plug-16 and project through the housing in the direction of the base body 15. The plug-in body-side connection elements 9, which are designed in the form of tabs, can, for example, be be attached directly to a board of the electronics.

Beim Herstellen der gewünschten Steckverbindung zwischen den basiskörperseitig und aufsteckkörperseitig vorgesehenen Anschlusselementen 8, 9 unter geeigneter Verschwenkung des Aufsteckkörpers 16 um die zu den Reihen R2, R3 parallele Achse S werden - aus geometrischen Gründen - zunächst die in Fig. 4 in einer hinteren Reihe angeordneten Flachstecker 9 mit den hierzu korrespondierenden U-Klemmen 8 in der hinteren Reihe R3 in Steckverbindung gebracht und erst anschließend die in den jeweils vorderen Reihen angeordneten Anschlusselemente miteinander verbunden, was eine schonende Herstellung der Steckverbindungen ermöglichst. Gleichermaßen erfolgt auch das Lösen der Steckverbindungen sukzessive für die beiden Reihen, womit das Lösen der Steckverbindungen ebenfalls weniger ruckartig durchführbar ist. Ferner garantiert die schwenkbare Lagerung des Aufsteckkörpers 16 am Basiskörper 15 eine stets lagerichtige Positionierung der verschiedenen Anschlusselemente 8, 9 relativ zueinander.When producing the desired plug connection between the base body side and plug body side provided connecting elements 8, 9 under suitable pivoting of the plug 16 about the parallel to the rows R 2 , R 3 axis S - for geometric reasons - first in Fig. 4 arranged in a rear row of flat plug 9 with the corresponding U-terminals 8 in the rear row R3 brought into plug connection and only then arranged in the respective front rows connecting elements connected to each other, which enables a gentle production of the connectors. Similarly, the release of the connectors is successively for the two rows, whereby the release of the connectors is also less jerky feasible. Furthermore, the pivotable mounting of the plug-on body 16 on the base body 15 guarantees an always positionally correct positioning of the various connecting elements 8, 9 relative to each other.
