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

Beschreibungdescription
Kaskadierbares KontaktSystem mit Unterbrechungs- und Einspeisemöglichkeit an jedem KontaktelementCascadable contact system with interruption and feeding options on every contact element
Die vorliegende Erfindung betrifft ein kaskadierbares Kontaktsystem zur Potentialweiterleitung und zur Potentialtrennung bzw. Potentialeinspeisung für elektrische Geräte in mo- dularer Aufbautechnik mit mindestens einem elektrisch leitfä- higen Kontaktelement.The present invention relates to a cascadable contact system for the transmission of potential and for the isolation or supply of potential for electrical devices in modular design with at least one electrically conductive contact element.
Bisher wurden bei derartigen elektrischen Geräten zur Ein- speisung 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 mo- dulare elektrische Gerät eingefügte Modul führt jedoch in nachteiliger Weise zu einem erhöhten Platzbedarf des modula- ren elektrischen Gerätes.Up to now, special separate modules have been used in such electrical devices for feeding in potentials and for forming potential islands within the electrical device, but these modules always occupy their own module slot. However, each module inserted for feeding potentials into the modular electrical device disadvantageously leads to an increased space requirement for 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 to provide a cascadable contact system for an electrical device in modular construction technology, with which the potential transfer between adjacent modules as well as the potential separation or potential supply is made possible.
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 Aufbau- technik, 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 an- geordnet 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 solved for a cascadable contact system for potential forwarding and for potential isolation or infeed with at least one electrically conductive contact element for electrical devices with modular construction technology, the modules of which can be placed next to one another, in that in a first module and a second module, the are arranged adjacent and can be contacted by means of the contact system, in each case at least one contact element is arranged, the contact element being essentially U- or is Z-shaped and wherein a resilient leg of the contact element arranged in the first module contacts a rigid leg of the contact element arranged in the second module in an electrically conductive manner.
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 aufge- steckten 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, a potential feed is provided for the contact system in such a way that a potential feed plug which can be detachably attached to the rigid leg of the contact element, in the plugged-on state, provides the contact between the resilient leg of the contact element arranged in the first module and the rigid leg of the second Module arranged contact element interrupts. Thus, at the point at which the potential feed connector is plugged onto the contact element, the potential transmission between adjacent contact elements is interrupted and instead from the contact element to which the potential feed plug was plugged, to all other contact elements that make contact with or with this contact element are electrically conductively connected, the potential fed in with the potential feed plug is passed on.
Wenn an die Module des elektrischen Gerätes z. B. Aktoren oder Sensoren zur Steuerung und/oder Überwachung eines tech- nischen 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. 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 ver- rastbar 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 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 being tapped from the contact elements arranged in the modules, and furthermore a first group of actuators or sensors a first supply voltage and where a second group of actuators or sensors require a second supply voltage different from the first supply voltage, it is furthermore advantageous if a number of contact elements corresponding to the number of different supply voltages is arranged in each module. If the potential feed plug can be locked to the module when it is plugged onto the contact element, if an insulating part can still be detachably connected to the potential feed plug, which can also be locked to the module when plugged in, and the locking of the insulating part to the module is also more difficult to release than the connection to the potential supply plug, then when the plugged-in potential supply plug is removed, the insulating part detaches from the potential supply plug and remains separately between the legs of the adjacent contact elements. This prevents an uncontrolled connection of electrically conductive contact elements of different potential.

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.According to FIG. 1, contact elements KEP are placed in the base parts ST of the modules M, M ', which are each arranged adjacent. As can be seen particularly from FIG. 2, the contact element KEP is essentially U-shaped, one of the legs of the U-shaped contact element KEP being a rigid leg SS in the exemplary embodiment according to FIG. 2 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 weitergeleite- ten 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.For tapping the potential passed on with a contact element KEP, the contact element KEP has further plug contacts SK, which in the exemplary embodiment according to FIG. 2 are arranged on the basis of the U-shaped contact element KEP and z. B. are designed according to FIG. 2 as a direct connector SK or can also be formed as an indirect connector.
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 SchenkelThe contacting of the contact elements KEP arranged in the base parts ST of the modules M, M 'can be seen particularly well with reference to FIG. 3. The arrangement of the contact elements KEP in the base part of the modules M, M 'is selected in the exemplary embodiment such that the base part ST of a first module M has cutouts into which the contact element KEP of this module M engages in such a way that the rigid leg SS makes contact with this contact element KEP is, and that the resilient leg FS of this contact element KEP the rigid leg
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.SS can contact the contact element KEP arranged in the base part ST of the adjacent module M '. For the transmission of potential, the individual contact elements KEP are thus spatially arranged in such a way that a resilient leg FS of a first contact element KEP always bears under moderate pressure on the rigid leg SS of the adjacent contact element KEP.
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 Po- tential zugeführt und über das Modul M, M' an das Nachbarmodul M, M' weitergegeben.Such a spatial arrangement is brought about directly if at least two modules M, M 'of the electrical device are arranged next to one another, for example on a top-hat rail HS, as shown in FIG. 1. This results in a closed chain of contact elements. In this way, applied potentials are passed on from contact element KEP to contact element KEP, that is to say, each individual module M, M 'is fed in with the input tential supplied and passed on via the module M, M 'to the neighboring module M, M'.
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 - in the exemplary embodiment three - identical contact elements KEP can be provided for different potentials, which thus form independent contact element chains or potential chains for the transmission of one potential each. In the exemplary embodiment, the three contact elements KEP, which are each arranged in a base part ST of a module M, M ', are aligned parallel to one another. In the case of several contact elements KEP in a module M, M 'for forwarding different potentials, the contact elements KEP of a module M, M' are of course isolated from one another.
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 aneinandergereih- ten 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.In order to create different potential islands and / or to have different potentials available for these individual potential islands, a new potential must be fed in. For this purpose, the contacting of the contact element chain formed from lined-up contact elements KEP must be specifically interrupted at a defined point. The previous potential is then present up to the point of interruption, after the point of interruption a potential to be fed in continues.
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 darge- stellt 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 Kontaktele- mentekette, d. h. im Verband der aneinandergereihten Module M, M' kein zusätzlicher Steckplatz benötigt.The interruption of the contact element chain and the feeding of a new potential is realized with a special potential feed connector PS, the exemplary embodiment of which is shown in FIG. 4 according to the exemplary embodiment. With the potential supply plug PS, it is possible due to its design to interrupt the contact element chain, to feed a new potential and to maintain the interruption of the contact element chain even when the plug is removed unintentionally. The potential supply within the contact ment chain, ie in the association of the modules M, M 'lined up, no additional slot is 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.5 is plugged onto the rigid leg SS of the contact element KEP, whereby it interrupts the contact point between the rigid leg SS and the resilient leg FS of the adjacent contact element KEP and thus has an insulating effect on the side of the previous potential.
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 Potentialeinspeisestek- kers PS zwischen das aus starrem Schenkel SS eines Kontakte- lements 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 .While the potential supply plug PS has an insulating effect on the side of the previous potential, it has an electrically conductive effect on the side of the potential to be newly built up. In the exemplary embodiment, the conductive part is designed as a socket BU. At the desired location in the contact element assembly, the potential feed plug PS with the socket part BU is pushed onto the rigid leg SS of the contact element KEP. The insulating area of the potential feed connector PS comes between the contact pair formed from rigid leg SS of a contact element KEP and resilient leg FS of an adjacent contact element KEP and presses the resilient leg FS of the adjacent contact element KEP aside. The electrical connection is interrupted at this point.
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 Poten- tialanschlußstecker PS angeordnete Rastnase bzw. Formschluß- aufnähme 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. 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 .The potential feed connector PS locks in the base part ST of the module M, M 'by means of locking elements not shown in the figures. As a locking element z. B. on the potential connector PS arranged locking lug or positive locking receptacles and in the base part ST of the module M, M 'a corresponding locking profile or positive locking element are used. Other detachable mechanical fixings for the potential supply plug PS are conceivable. For example, the latching can also take place between the potential feed connector PS and the rigid leg SS. Via the electrically conductive part of the potential feed plug PS, which is plugged onto the rigid leg SS of the contact element KEP, in the exemplary embodiment the socket BU, a new potential can now be fed in via the electrical line EL connected to the potential feed plug PS and passed on from here via the contact element chain become. The potential is transmitted to the end of the contact element chain or to the 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 mecha- nisch lösbar verbunden. Während des Steckens des Poten- tialeinspeisesteckers 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.In the exemplary embodiment, according to an advantageous embodiment of the invention, on the insulating side of the potential feed connector PS, an insulating part IT is mechanically detachably connected to the latter. While the potential feed connector PS is plugged onto the contact element KEP, this insulating part IT is likewise placed between the two contact element legs SS, FS to be separated and latches in accordance with the above description with the base part ST of the module M, M 'in which the contact element KEP , on the rigid leg SS of which the potential supply plug 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) un- terschiedlicher Potentiale wirksam verhindert.If the potential supply plug PS is removed, the insulating part IT detaches from the potential supply plug PS and remains, regardless of the potential supply plug PS, in the base part ST of the module M, M ', that is to say between the two legs SS, FS of the contact elements KEP to be separated. This effectively prevents uncontrolled connection (short circuit) of different potentials.
Dieser Sachverhalt ist anhand von Fig. 5 besonders deutlich ersichtlich. Fig. 5 zeigt innerhalb der aus benachbarten Kontaktelementen KEP gebildeten Kontaktelementekette einen auf- gesteckten Potentialeinspeisestecker PS mit Isolierteil 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.This fact can be seen particularly clearly on the basis of FIG. 5. 5 shows within the contact element chain formed from adjacent contact elements KEP an attached potential feed plug PS with an insulating part IT. The insulating part IT of the other potential feed plug PS of this figure, which has been released from the contact element chain, however, remains between the adjacent contact elements KEP and prevents their electrically conductive contact.
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 Poten- tialeinspeisestecker PS. Das Stecken des Potentialeinspeise- steckers PS bewirkt eine zwingende Übergabe des Isolierteils IT vom Potentialeinspeisestecker PS an das Sockelteil ST des Moduls M, M' .This is achieved in that the locking of the insulating part IT with the base part ST of the module is much more difficult to solve than the connection between the insulating part IT and the potential supply plug PS. The plugging in of the potential supply plug PS causes the insulating part IT to be transferred from the potential supply plug PS to the base part ST of the module M, M '.
Soll die Verbindung der vorher getrennten Kontaktelementeket- te 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.If the connection of the previously separated contact element chain is to be restored, i. H. If the removal of the potential supply plug PS is deliberately desired, the isolating part IT must be deliberately removed using a tool (e.g. a screwdriver) or - depending on the design - also by hand.
Der Potentialeinspeisestecker PS weist darüber hinaus an seinen Außenflächen in den Figuren nicht dargestellte Rastele- mente 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 Potentialeinspeisestek- kern PS gemeinsam auf die entsprechenden, im Sockelteil ST des Moduls M, M' angeordneten Kontaktelemente KEP aufzustek- ken. Dies führt sowohl zu einer Arbeitserleichterung als auch zu einer Verbesserung der Übersichtlichkeit bei der Führung der elektrischen Leitungen EL, da zusammengehörige elektri- sehe 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 has on its outer surfaces not shown in the figures locking elements or positive locking elements or positive locking receptacles with which several potential feed connectors PS can be releasably connected to one another. With potential supply plugs PS configured in this way, it is advantageously possible to combine a large number of potential supply plugs PS into a jointly manageable unit and then to plug the group of potential supply plugs PS thus formed together onto the corresponding contact elements KEP arranged in the base part ST of the module M, M ' - ken. This not only makes work easier, but also improves the clarity when routing the electrical lines EL, since associated electrical see lines over the group of potential supply plugs PS are combined and can be handled together. The potential feed connector PS is plugged into the contact element KEP of the module M, M 'from which the feed-in of a new potential is to begin. This means that no additional module slot in the group of cascaded modules M, M 'is necessary.
Abweichend vom Ausführungsbeispiel gemäß den zuvor beschrie- benen Figuren kann die Kontaktelementekette auch derart ausgebildet sein, daß das Kontaktelement KEP im wesentlichen Z- för ig 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 exemplary embodiment according to the figures described above, the contact element chain can also be designed such that the contact element KEP is essentially Z-shaped with two essentially parallel legs and a diagonal base, one of the legs being a resilient leg FS and the other leg is designed as a rigid leg SS.
Eine weitere Alternative besteht darin, daß jeweils ein Kontaktelement KEP mit zwei starren Schenkeln SS einem Kontaktelement KEP mit zwei federnden Schenkeln FS benachbart ange- ordnet 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 a contact element KEP with two rigid legs SS is arranged adjacent to a contact element KEP with two resilient legs FS. In this case, too, a resilient leg FS meets a rigid leg SS at the contact point between two contact elements KEP, so that a previously described contact is made possible even in the case of deviating contact elements KEP.
