Abstract

In modules (M, M') adjacent to each others, fitted with an electric apparatus, contact elements (KEP) are mounted which engage matching recesses in the module casing, so that contact elements (KEP) can be contacted from outside, i.e. by a similar contact element (KEP) of the adjacent module (M, M'). The substantially U-shaped contact element (KEP) has a spring rod (SS) and a fixed rod (FS), while the spring rod (FS) of a first contact element (KEP) extends to touch the fixed rod (SS) of an adjacent contact element (KEP).

Description

Die vorliegende Erfindung betrifft ein kaskadierbares Kontaktsystem zur Potentialweiterleitung und zur Potentialtrennung bzw. Potentialeinspeisung für elektrische Geräte in modularer Aufbautechnik mit mindestens einem elektrisch leitfähigen Kontaktelement (siehe zum Beispiel EP-A-0 364 618).The present invention relates to a cascadable contact system for potential transmission and isolation or potential feed for electrical devices in modular Construction technology with at least one electrically conductive Contact element (see for example EP-A-0 364 618).

Bisher wurden bei derartigen elektrischen Geräten zur Einspeisung von Potentialen und zur Bildung von Potentialinseln innerhalb des elektrischen Gerätes spezielle separate Module verwendet, die jedoch stets einen eigenen Modulsteckplatz beanspruchen. Jedes zur Einspeisung von Potentialen in das modulare elektrische Gerät eingefügte Modul führt jedoch in nachteiliger Weise zu einem erhöhten Platzbedarf des modularen elektrischen Gerätes.So far, such electrical devices have been used for feeding of potentials and for the formation of potential islands special separate modules within the electrical device used, but which always occupy their own module slot. Each for feeding potentials into the modular electrical device inserted module leads however in disadvantageous to an increased space requirement of the modular electrical device.

Aufgabe der Erfindung ist es daher, für ein elektrisches Gerät in modularer Aufbautechnik ein kaskadierbares Kontaktsystem zu schaffen, mit dem sowohl die Potentialweiterleitung zwischen benachbarten Modulen als auch die Potentialtrennung bzw. Potentialeinspeisung ermöglicht ist.The object of the invention is therefore for an electrical device a cascadable contact system in modular design to create with both the potential forwarding between adjacent modules as well as the potential isolation or potential supply is enabled.

Die Aufgabe wird für ein kaskadierbares Kontaktsystem zur Potentialweiterleitung und zur Potentialtrennung bzw. Potentialeinspeisung mit mindestens einem elektrisch leitfähigen Kontaktelement für elektrische Geräte mit modularer Aufbautechnik, deren Module nebeneinander plazierbar sind, dadurch gelöst, daß in einem ersten Modul und einem zweiten Modul, die benachbart angeordnet sind und mittels des Kontaktsystems kontaktierbar sind, jeweils mindestens ein Kontaktelement angeordnet ist, wobei das Kontaktelement im wesentlichen U- oder Z-förmig ausgebildet ist und wobei ein federnder Schenkel des im ersten Modul angeordneten Kontaktelementes einen starren Schenkel des im zweiten Modul angeordneten Kontaktelementes elektrisch leitend kontaktiert.The task is for a cascadable contact system for potential transmission and for potential isolation or potential feed with at least one electrically conductive Contact element for electrical devices with modular construction technology, whose modules can be placed next to each other solved that in a first module and a second module, which are arranged adjacent and by means of the contact system are contacted, at least one contact element is arranged is, the contact element is essentially U- or Z-shaped and with a resilient leg of the contact element arranged in the first module rigid leg of the contact element arranged in the second module contacted electrically conductive.

In einer vorteilhaften Ausgestaltung der Erfindung ist für das Kontaktsystem eine Potentialeinspeisung in der Form vorgesehen, daß ein auf den starren Schenkel des Kontaktelementes lösbar aufsteckbarer Potentialeinspeisestecker im aufgesteckten Zustand die Kontaktierung zwischen federndem Schenkel des im ersten Modul angeordneten Kontaktelementes und starrem Schenkel des im zweiten Modul angeordneten Kontaktelementes unterbricht. Damit wird an der Stelle, an der der Potentialeinspeisestecker auf das Kontaktelement aufgesteckt wird, die Potentialweiterleitung zwischen benachbarten Kontaktelementen unterbrochen und statt dessen ab dem Kontaktelement, auf das der Potentialeinspeisestecker aufgesteckt wurde, an sämtliche weiteren Kontaktelemente, die mit diesem Kontaktelement kontaktiert bzw. mit diesem elektrisch leitend verbunden sind, das mit dem Potentialeinspeisestecker eingespeiste Potential weitergeleitet.In an advantageous embodiment of the invention is for the contact system provides a potential feed in the form, that one on the rigid leg of the contact element Detachably pluggable potential feed connector in the plugged on Condition the contact between the resilient leg of the contact element arranged in the first module and rigid leg of the contact element arranged in the second module interrupts. Thus, at the point where the Potential feed connector plugged onto the contact element the potential transfer between adjacent contact elements interrupted and instead from the contact element, onto which the potential feed connector is attached was to all other contact elements with this Contacted contact element or electrically conductive with this are connected, which is fed in with the potential feed connector Potential passed on.

Wenn an die Module des elektrischen Gerätes z. B. Aktoren oder Sensoren zur Steuerung und/oder Überwachung eines technischen Prozesses angeschlossen sind, wobei die Versorgungsspannung dieser Aktoren bzw. Sensoren von den in den Modulen angeordneten Kontaktelementen abgegriffen wird und wobei weiterhin eine erste Gruppe von Aktoren bzw. Sensoren eine erste Versorgungsspannung benötigen und wobei eine zweite Gruppe von Aktoren bzw. Sensoren ein zweite, von der ersten Versorgungsspannung verschiedene Versorgungsspannung benötigen, ist es weiterhin von Vorteil, wenn in jedem Modul eine der Anzahl der unterschiedlichen Versorgungsspannungen entsprechende Anzahl von Kontaktelementen angeordnet ist. If the modules of the electrical device such. B. actuators or sensors for controlling and / or monitoring a technical Process are connected, the supply voltage of these actuators or sensors from those in the modules arranged contact elements is tapped and wherein continues a first group of actuators or sensors a first Need supply voltage and being a second group a second of actuators or sensors, of the first supply voltage need different supply voltage is it is still an advantage if each module has one of the number number corresponding to the different supply voltages of contact elements is arranged.

Wenn der Potentialeinspeisestecker beim Aufstecken auf das Kontaktelement mit dem Modul verrastbar ist, wenn weiterhin mit dem Potentialeinspeisestecker lösbar ein Isolierteil verbindbar ist, welches beim Aufstecken auch mit dem Modul verrastbar ist, und weiterhin die Verrastung des Isolierteils mit dem Modul schwerer lösbar ist als die Verbindung mit dem Potentialeinspeisestecker, dann löst sich beim Entfernen des aufgesteckten Potentialeinspeisesteckers das Isolierteil vom Potentialeinspeisestecker und verbleibt separat zwischen den Schenkeln der benachbarten Kontaktelemente. Somit wird ein unkontrolliertes Zusammenschließen elektrisch leitfähiger Kontaktelemente unterschiedlichen Potentials verhindert.If the potential feed connector is attached to the Contact element can be locked to the module if continued an isolating part can be releasably connected to the potential feed connector which can also be locked to the module when plugged in and the locking of the insulating part is more difficult to solve with the module than the connection with the Potential feed connector, then detaches when the plugged-in potential supply plug the insulating part from Potential feed connector and remains separately between the Legs of the adjacent contact elements. Thus a uncontrolled interconnection of electrically conductive Contact elements of different potential prevented.

Gemäß Fig. 1 sind in den Sockelteilen ST der Module M, M', die jeweils benachbart angeordnet sind, Kontaktelemente KEP plaziert. Wie besonders aus Fig. 2 ersichtlich ist, ist das Kontaktelement KEP im wesentlichen U-förmig ausgebildet, wobei im Ausführungsbeispiel gemäß Fig. 2 einer der Schenkel des U-förmigen Kontaktelementes KEP als starrer Schenkel SS und der andere Schenkel des U-förmigen Kontaktelementes KEP als federnder Schenkel FS ausgebildet ist.1 are in the base parts ST of the modules M, M ', which are each arranged adjacent, contact elements KEP placed. As can be seen particularly from FIG. 2, this is Contact element KEP essentially U-shaped, wherein in the embodiment of FIG. 2 one of the legs of the U-shaped contact element KEP as a rigid leg SS and the other leg of the U-shaped contact element KEP is designed as a resilient leg FS.

Zum Abgreifen des mit einem Kontaktelement KEP weitergeleiteten Potentials weist das Kontaktelement KEP weitere Steckkontakte SK auf, die im Ausführungsbeispiel gemäß Fig. 2 auf der Basis des U-förmigen Kontaktelementes KEP angeordnet sind und z. B. gemäß Fig. 2 als direkter Steckverbinder SK ausgebildet sind oder auch als indirekte Steckverbinder ausgebildet sein können.To tap the one forwarded with a contact element KEP Potential, the contact element KEP has further plug contacts SK on which in the embodiment of FIG. 2 on the Base of the U-shaped contact element KEP are arranged and e.g. B. as shown in FIG. 2 as a direct connector SK are or also be designed as indirect connectors can.

Die Kontaktierung der in den Sockelteilen ST der Module M, M' angeordneten Kontaktelemente KEP ist besonders gut anhand von Fig. 3 ersichtlich. Die Anordnung der Kontaktelemente KEP im Sockelteil der Module M, M' ist beim Ausführungsbeispiel derart gewählt, daß das Sockelteil ST eines ersten Moduls M Aussparungen aufweist, in die das Kontaktelement KEP dieses Moduls M derart eingreift, daß der starre Schenkel SS dieses Kontaktelements KEP kontaktierbar ist, und daß der federnde Schenkel FS dieses Kontaktelements KEP den starren Schenkel SS des im Sockelteil ST des benachbarten Moduls M' angeordneten Kontaktelements KEP kontaktieren kann. Zur Potentialweiterleitung sind damit die einzelnen Kontaktelemente KEP räumlich derart angeordnet, daß immer ein federnder Schenkel FS eines ersten Kontaktelementes KEP unter mäßigem Druck am starren Schenkel SS des Nachbarkontaktelementes KEP anliegt.The contacting of the base parts ST of the modules M, M ' arranged contact elements KEP is particularly good on the basis of Fig. 3 can be seen. The arrangement of the contact elements KEP in Base part of the modules M, M 'is such in the embodiment chosen that the base part ST of a first module M recesses has, in which the contact element KEP of this module M engages such that the rigid leg SS this Contact element KEP is contactable, and that the resilient Leg FS of this contact element KEP the rigid leg SS arranged in the base part ST of the adjacent module M ' Contact element KEP can contact. For transmission of potential are the individual contact elements KEP spatial arranged such that always a resilient leg FS a first contact element KEP under moderate pressure on rigid leg SS of the adjacent contact element KEP is present.

Eine derartige räumliche Anordnung wird unmittelbar bewirkt, wenn mindestens zwei Module M, M' des elektrischen Gerätes z.B. auf einer Hutschiene HS, wie in Fig. 1 dargestellt, nebeneinander angeordnet sind. Damit ergibt sich eine geschlossene Kontaktelementekette. Anliegende Potentiale werden so von Kontaktelement KEP zu Kontaktelement KEP weitergeleitet, d. h. jedem einzelnen Modul M, M' wird das eingespeiste Potential zugeführt und über das Modul M, M' an das Nachbarmodul M, M' weitergegeben.Such a spatial arrangement is immediately effected if at least two modules M, M 'of the electrical device e.g. on a top-hat rail HS, as shown in Fig. 1, side by side are arranged. This results in a closed one Contact element chain. This is how existing potentials become forwarded from contact element KEP to contact element KEP, d. H. Each individual module M, M 'is the potential fed fed and via the module M, M 'to the neighboring module M, M 'passed on.

Für jedes Modul M, M' des elektrischen Gerätes können mehrere - im Ausführungsbeispiel drei - gleichartige Kontaktelemente KEP für unterschiedliche Potentiale vorgesehen sein, die damit unabhängige Kontaktelementeketten oder Potentialketten zur Weiterleitung jeweils eines Potentials bilden. Im Ausführungsbeispiel sind die drei Kontaktelemente KEP, die jeweils in einem Sockelteil ST eines Moduls M, M' angeordnet sind, zueinander parallel ausgerichtet. Im Falle mehrerer Kontaktelemente KEP in einem Modul M, M' zur Weiterleitung unterschiedlicher Potentiale sind die Kontaktelemente KEP eines Moduls M, M' untereinander selbstverständlich isoliert.For each module M, M 'of the electrical device, several can - In the exemplary embodiment three - identical contact elements CEP can be provided for different potentials independent contact element chains or potential chains form a potential for each transmission. In the embodiment are the three contact elements KEP, each are arranged in a base part ST of a module M, M ', aligned parallel to each other. In the case of multiple contact elements KEP in a module M, M 'to forward different Potentials are the contact elements KEP one Module M, M 'of course isolated from each other.

Um verschiedene Potentialinseln zu schaffen und/oder aber unterschiedliche Potentiale für diese einzelnen Potentialinseln zur Verfügung zu haben, muß ein neues Potential eingespeist werden. Dazu muß die Kontaktierung der aus aneinandergereihten Kontaktelementen KEP gebildeten Kontaktelementekette gezielt an einer definierten Stelle unterbrochen werden. Bis zur Unterbrechungsstelle liegt dann das bisherige Potential an, nach der Unterbrechungsstelle geht ein neu einzuspeisendes Potential weiter.To create different potential islands and / or different ones Potentials for these individual potential islands To have available a new potential become. To do this, the contacting of the lined up Contact elements KEP specifically formed contact element chain be interrupted at a defined point. To the previous potential then lies at the point of interruption on, after the point of interruption a new one goes into the grid Potential further.

Die Unterbrechung der Kontaktelementekette und die Einspeisung eines neuen Potentials wird mit einem speziellen Potentialeinspeisestecker PS realisiert, dessen exemplarische Ausgestaltung gemäß dem Ausführungsbeispiel in Fig. 4 dargestellt ist. Mit dem Potentialeinspeisestecker PS ist es aufgrund dessen konstruktiver Ausgestaltung möglich, die Kontaktelementekette zu unterbrechen, ein neues Potential einzuspeisen und die Unterbrechung der Kontaktelementekette auch bei ungewolltem Entfernen des Steckers aufrechtzuerhalten. Dabei wird zur Potentialeinspeisung innerhalb der Kontaktelementekette, d. h. im Verband der aneinandergereihten Module M, M' kein zusätzlicher Steckplatz benötigt.The interruption of the contact element chain and the infeed a new potential is created with a special potential connector PS realized, its exemplary design according to the embodiment shown in Fig. 4 is. With the potential supply plug PS it is due its constructive design possible, the contact element chain to interrupt to inject a new potential and the interruption of the contact element chain too if the plug is removed unintentionally. The potential supply within the contact element chain, d. H. in the association of lined up modules M, M 'no additional slot required.

Der Potentialeinspeisestecker PS wird gemäß Fig. 5 auf den starren Schenkel SS des Kontaktelements KEP aufgesteckt, wobei er die Kontaktstelle zwischen starrem Schenkel SS und anliegendem federndem Schenkel FS des benachbarten Kontaktelements KEP unterbricht und damit zur Seite des bisherigen Potentials isolierend wirkt.The potential feed connector PS is shown in FIG. 5 on the rigid leg SS of the contact element KEP, where he the contact point between rigid leg SS and the adjacent resilient leg FS of the adjacent contact element KEP interrupts and thus to the side of the previous potential has an insulating effect.

Während der Potentialeinspeisestecker PS zur Seite des bisherigen Potentials isolierend wirkt, wirkt er zur Seite des neu aufzubauenden Potentials elektrisch leitend. Der leitfähige Teil ist im Ausführungsbeispiel als Buchse BU ausgeführt. An der gewünschten Stelle im Kontaktelementeverband wird der Potentialeinspeisestecker PS mit dem Buchsenteil BU auf den starren Schenkel SS des Kontaktelements KEP geschoben. Dabei gelangt der isolierende Bereich des Potentialeinspeisestekkers PS zwischen das aus starrem Schenkel SS eines Kontaktelements KEP und federndem Schenkel FS eines benachbarten Kontaktelements KEP gebildete Kontaktpaar und drückt den federnden Schenkel FS des benachbarten Kontaktelements KEP zur Seite. Die elektrische Verbindung wird damit an dieser Stelle unterbrochen.During the potential feed connector PS to the side of the previous one Potential isolating, he acts on the side of the new potential to be built electrically conductive. The conductive In the exemplary embodiment, part is designed as a socket BU. On The potential feed connector becomes the desired position in the contact element assembly PS with the socket part BU on the rigid leg SS of the contact element KEP pushed. Here reaches the isolating area of the potential feed connector PS between the rigid leg SS of a contact element KEP and resilient leg FS of an adjacent contact element KEP formed contact pair and presses the resilient Leg FS of the adjacent contact element KEP to the side. The electrical connection is at this point interrupted.

Der Potentialeinspeisestecker PS verrastet im Sockelteil ST des Moduls M, M' mittels in den Abbildungen nicht dargestellter Rastelemente. Als Rastelement kann z. B. eine am Potentialanschlußstecker PS angeordnete Rastnase bzw. Formschlußaufnahme und im Sockelteil ST des Moduls M, M' ein dazu korrespondierendes Rastprofil bzw. Formschlußelement zum Einsatz kommen. Andere lösbare mechanische Fixierungen für den Potentialeinspeisestecker PS sind denkbar. Zum Beispiel kann die Verrastung auch zwischen Potentialeinspeisestecker PS und starrem Schenkel SS erfolgen. The potential feed connector PS snaps into the base part ST of the module M, M 'by means of not shown in the figures Locking elements. As a locking element z. B. one at the potential connector PS arranged locking lug or positive locking and in the base part ST of the module M, M 'a corresponding one Locking profile or form-locking element for use come. Other detachable mechanical fixings for the potential feed connector PS are conceivable. For example, the Locking also between the PS and rigid leg SS.

Über den elektrisch leitenden Teil des auf den starren Schenkel SS des Kontaktelementes KEP aufgesteckten Potentialeinspeisesteckers PS, im Ausführungsbeispiel die Buchse BU, kann jetzt über die an den Potentialeinspeisestecker PS angeschlossene elektrische Leitung EL ein neues Potential eingespeist werden und von dieser Stelle aus über die Kontaktelementekette weitergeleitet werden. Die Potentialweiterleitung erfolgt bis zum Ende der Kontaktelementekette oder bis zur nächsten Unterbrechungs- bzw. Einspeisungsstelle.Over the electrically conductive part of the on the rigid leg SS of the contact element KEP plugged potential feed connector PS, in the exemplary embodiment the BU socket, can now via the connected to the potential feed connector PS electrical line EL fed a new potential be and from this point on the contact element chain to get redirected. The transmission of potential takes place up to the end of the contact element chain or up to next interruption or feed point.

Im Ausführungsbeispiel ist gemäß einer vorteilhaften Ausgestaltung der Erfindung auf der isolierenden Seite des Potentialeinspeisesteckers PS mit diesem ein Isolierteil IT mechanisch lösbar verbunden. Während des Steckens des Potentialeinspeisesteckers PS auf das Kontaktelement KEP wird dieses Isolierteil IT gleichfalls zwischen den beiden zu trennenden Kontaktelementeschenkeln SS,FS plaziert und verrastet entsprechend der obigen Beschreibung mit dem Sockelteil ST desjenigen Moduls M, M', in dem sich das Kontaktelement KEP, auf dessen starren Schenkel SS der Potentialeinspeisestecker PS gesteckt wurde, befindet.The exemplary embodiment is according to an advantageous embodiment the invention on the insulating side of the potential feed connector PS with this an insulating part IT mechanically releasably connected. While plugging in the potential feed connector PS on the contact element KEP will this Isolating part IT also between the two to be separated Contact element legs SS, FS placed and locked according to the description above with the base part ST of the module M, M 'in which the contact element KEP, on its rigid leg SS the potential feed connector PS was inserted.

Wird der Potentialeinspeisestecker PS entfernt, löst sich das Isolierteil IT vom Potentialeinspeisestecker PS und verbleibt weiterhin, unabhängig vom Potentialeinspeisestecker PS, im Sockelteil ST des Moduls M, M', also zwischen den beiden zu trennenden Schenkeln SS,FS der Kontaktelemente KEP. Somit wird ein unkontrolliertes Zusammenschließen (Kurzschluß) unterschiedlicher Potentiale wirksam verhindert.If the potential supply plug PS is removed, this will be solved Insulating part IT from the potential supply plug PS and remains continue, regardless of the potential feed connector PS, in Base part ST of the module M, M ', that is between the two separating legs SS, FS of the contact elements KEP. Consequently an uncontrolled connection (short circuit) becomes different Potentials effectively prevented.

Dieser Sachverhalt ist anhand von Fig. 5 besonders deutlich ersichtlich. Fig. 5 zeigt innerhalb der aus benachbarten Kontaktelementen KEP gebildeten Kontaktelementekette einen aufgesteckten Potentialeinspeisestecker PS mit Isolierteil IT. This fact is particularly clear on the basis of FIG. 5 evident. Fig. 5 shows inside of adjacent contact elements KEP formed contact element chain an attached Potential supply plug PS with insulating part IT.

Das Isolierteil IT des anderen Potentialeinspeisestecker PS dieser Abbildung, der aus der Kontaktelementekette gelöst wurde, verbleibt dagegen weiterhin zwischen den benachbarten Kontaktlementen KEP und verhindert deren elektrisch leitende Kontaktierung.The insulating part IT of the other potential supply plug PS this figure, which is released from the contact element chain on the other hand remains between the neighboring ones Contact elements KEP and prevents their electrically conductive Contacting.

Dies wird erreicht, indem die Verrastung des Isolierteils IT mit dem Sockelteil ST des Moduls wesentlich schwerer lösbar ist, als die Verbindung zwischen Isolierteil IT und Potentialeinspeisestecker PS. Das Stecken des Potentialeinspeisesteckers PS bewirkt eine zwingende Übergabe des Isolierteils IT vom Potentialeinspeisestecker PS an das Sockelteil ST des Moduls M, M'.This is achieved by locking the insulating part IT with the base part ST of the module much more difficult to solve is as the connection between the isolating part IT and the potential supply connector PS. The insertion of the potential feed connector PS causes the insulating part to be transferred IT from the potential feed connector PS to the base part ST of the Module M, M '.

Soll die Verbindung der vorher getrennten Kontaktelementekette wiederhergestellt werden, d. h. ist die Entfernung des Potentialeinspeisesteckers PS bewußt gewünscht, muß das Isolierteil IT mittels eines Werkzeugs (z. B. eines Schraubendrehers) oder - je nach konstruktiver Ausführung - auch per Hand bewußt entfernt werden.Should the connection of the previously separated contact element chain be restored, d. H. is the removal of the potential feed connector PS deliberately desired, the insulating part IT using a tool (e.g. a screwdriver) or - depending on the design - also by Hand deliberately removed.

Der Potentialeinspeisestecker PS weist darüber hinaus an seinen Außenflächen in den Figuren nicht dargestellte Rastelemente oder Formschlußelemente bzw. Formschlußaufnahmen auf, mit denen mehrere Potentialeinspeisestecker PS lösbar miteinander in Verbindung gebracht werden können. Mit derart ausgestalteten Potentialeinspeisesteckern PS ist es vorteilhafterweise möglich, eine Vielzahl von Potentialeinspeisesteckern PS zu einer gemeinsam handhabbaren Einheit zusammenzufassen und dann die so gebildete Gruppe von Potentialeinspeisestekkern PS gemeinsam auf die entsprechenden, im Sockelteil ST des Moduls M, M' angeordneten Kontaktelemente KEP aufzustekken. Dies führt sowohl zu einer Arbeitserleichterung als auch zu einer Verbesserung der Übersichtlichkeit bei der Führung der elektrischen Leitungen EL, da zusammengehörige elektrische Leitungen über die Gruppe von Potentialeinspeisesteckern PS zusammengefaßt sind und gemeinsam handhabbar sind. Der Potentialeinspeisestecker PS wird auf das Kontaktelement KEP desjenigen Moduls M, M' gesteckt, von welchem aus die Einspeisung eines neuen Potentials beginnen soll. Damit ist kein zusätzlicher Modulsteckplatz im Verband der kaskadierten Module M, M' notwendig.The potential feed connector PS also points to its External surfaces not shown in the figures or positive locking elements or positive locking receptacles, with which several potential feed plugs PS releasably together can be associated. With such a design It is advantageous for PS power supply plugs possible, a variety of potential supply plugs Combine PS into a jointly manageable unit and then the group of potential feed plugs thus formed PS together on the corresponding, in the base part ST of the module M, M 'arranged contact elements KEP. This leads to both easier work as well to improve the clarity of the management of the electrical lines EL, since related electrical Cables via the group of potential supply plugs PS are summarized and can be handled together. The potential feed connector PS is on the contact element KEP of the module M, M 'inserted from which the Feeding a new potential should begin. So that is no additional module slot in the cascaded association Modules M, M 'necessary.

Abweichend vom Ausführungsbeispiel gemäß den zuvor beschriebenen Figuren kann die Kontaktelementekette auch derart ausgebildet sein, daß das Kontaktelement KEP im wesentlichen Z-förmig mit zwei im wesentlichen parallelen Schenkeln und einer diagonalen Basis ausgebildet ist, wobei einer der Schenkel als federnder Schenkel FS und der andere Schenkel als starrer Schenkel SS ausgebildet ist.Deviating from the embodiment according to the previously described Figures, the contact element chain can also be designed in this way be that the contact element KEP substantially Z-shaped with two substantially parallel legs and one diagonal base is formed, one of the legs as a resilient leg FS and the other leg as rigid leg SS is formed.

Eine weitere Alternative besteht darin, daß jeweils ein Kontaktelement KEP mit zwei starren Schenkeln SS einem Kontaktelement KEP mit zwei federnden Schenkeln FS benachbart angeordnet ist. Auch in diesem Fall trifft an der Kontaktstelle zwischen zwei Kontaktelementen KEP jeweils ein federnder Schenkel FS auf einen starren Schenkel SS, so daß auch bei abweichend ausgestalteten Kontaktelementen KEP eine zuvor beschriebene Kontaktierung ermöglicht ist.Another alternative is that each have a contact element KEP with two rigid legs SS a contact element KEP with two resilient legs FS arranged adjacent is. In this case also meets at the contact point between two contact elements KEP each a resilient Leg FS on a rigid leg SS, so that at deviatingly designed contact elements KEP a previously described Contacting is possible.
