Description

Die Erfindung betrifft einen Steckverbinder zur Verbindung von Abschnitten einer mehrphasigen Durchgangsverdrahtung, mit einem Steckgehäuse, welches einen Steckfortsatz aufweist und mit einem Buchsengehäuse, welches einen Aufnahmeraum für den Steckfortsatz des Steckgehäuses ausbildet, mit Kammern im Steckfortsatz, die der Aufnahme von Kontakten dienen.The invention relates to a connector for connecting sections of multi-phase through wiring, with a plug-in housing which has a plug-in extension and with a socket housing which forms a receiving space for the plug-in extension of the plug-in housing, with chambers in the plug-in extension which are used to accommodate contacts.

In sehr großen Räumen, beispielsweise in industriell genutzten Gebäuden wie Lagerhallen oder Produktionshallen, in Räumen des Groß- und Einzelhandels oder auch in Großraumbüros wird mit einer Vielzahl von Leuchten für eine dem jeweiligen Zweck dienende Beleuchtung gesorgt. Insbesondere finden linienartige Lichtbänder Verwendung, die von in der Regel unmittelbar hintereinander angeordneten Leuchten gebildet werden. Alternative Lösungen realisieren die Beleuchtung mit zueinander beabstandeten Leuchten. Diesen Installationen ist gemein, dass sie in der Regel an einem durchgehenden Leitungsstrang angebunden werden, der sogenannten Durchgangsverdrahtung. Diese versorgt die einzelnen Leuchten mit Elektrizität.In very large rooms, for example in industrially used buildings such as warehouses or production halls, in wholesalers and retailers or in open-plan offices, a large number of lights are used to provide lighting for the respective purpose. In particular, line-like light strips are used, which are formed by lights that are usually arranged directly one behind the other. Alternative solutions implement the lighting with spaced apart luminaires. What these installations have in common is that they are usually connected to a continuous line of cables, the so-called through wiring. This supplies the individual lights with electricity.

Die Durchgangsverdrahtung ist in der Regel mehrphasig, so dass neben einem Neutralleiter und einem Erdungsleiter wenigstens zwei, in der Regel jedoch drei Phasen, bezeichnet als L1, L2 und L3, den Leitungsstrang bilden. Dies hat zunächst den Vorteil, dass die durch die Vielzahl der Verbraucher hervorgerufene Abnahmelast auf mehrere Phasen verteilt werden kann. Aber auch unabhängig hiervon bietet die Verteilung der Abnehmer, hier insbesondere der Leuchten, auf verschiedene Phasen die Möglichkeit, Leuchtengruppen zu bilden, die getrennt schaltbar sind.The through-wiring is usually multi-phase, so that in addition to a neutral conductor and a grounding conductor, at least two, but usually three phases, designated as L1, L2 and L3, form the wiring harness. This initially has the advantage that the acceptance load caused by the large number of consumers can be distributed over several phases. But also independently of this, the distribution of the consumers, in this case the lights in particular, to different phases offers the possibility of forming groups of lights that can be switched separately.

Die Durchgangsverdrahtung verfügt entsprechend der geplanten Lichtinstallation über verschiedene Abschnitte, die über Steckverbinder gekoppelt sind. Im Bereich eines jeden Steckverbinders besteht darüber hinaus die Möglichkeit der Anbindung eines elektrischen Verbrauchers, insbesondere einer Leuchte.The through wiring has different sections that have connectors, depending on the planned light installation are coupled. In the area of each connector there is also the possibility of connecting an electrical consumer, in particular a lamp.

Insbesondere ist es bei zu Lichtbändern zusammenfügbaren Leuchten bekannt, dass die Steckverbinder an den Leuchtenstirnseiten angeordnet sind und durch Herstellung einer Steckverbindung zwischen den Leuchten bei gegenseitiger Anordnung eine elektrische wie auch mechanische Kopplung herbeigeführt wird. Bei solchen Systemen bildet die in der Leuchte vorhandene, interne Verdrahtung jeweils einen Abschnitt der Durchgangsverdrahtung aus.In particular, it is known in the case of lights that can be joined together to form strips of light that the plug connectors are arranged on the front sides of the lights and that an electrical and mechanical coupling is brought about by establishing a plug connection between the lights when they are mutually arranged. In such systems, the internal wiring in the luminaire forms a section of the through wiring.

Aus dem Stand der Technik ( DE 10 2012 002 588 A1 ) ist es bekannt, in dem Leitungsstrang der Durchgangsverdrahtung Phasenwahlelemente einzufügen. Mit diesen ist es möglich, bei einer bestehenden Installation im Nachhinein für nachgeschaltete Verbraucher, insbesondere Leuchten, die die Leuchte versorgende Phase umzukonfigurieren, beispielsweise einem Phasenwechsel von der Phase L1 auf die Phase L2 durchzuführen. Auf diese Weise ist es im Nachhinein möglich, das Beleuchtungssystem hinsichtlich beispielsweise seiner Schaltbarkeit oder aber auch hinsichtlich der Abnahmelast auf einzelnen Phasen neu zu konfigurieren.From the state of the art ( DE 10 2012 002 588 A1 ) It is known to insert phase selection elements in the wiring harness of the through wiring. With these it is possible, in the case of an existing installation, to reconfigure the phase supplying the lamp, for example a phase change from phase L1 to phase L2, for downstream consumers, in particular lamps. In this way it is possible retrospectively to reconfigure the lighting system with regard to, for example, its switchability or also with regard to the acceptance load on individual phases.

Je nach Art der gewerblichen Nutzung werden an die Elektroinstallationen bestimmte Anforderungen gestellt. Hierzu zählt beispielsweise der Schutz gegen Feuchtigkeit oder im Zweifelsfall auch der Schutz gegen Gaseintritt. Bei besonders zu schützenden Elektroinstallationen stellt jeder Koppelpunkt zwischen den Leitern oder der Übergabepunkte an einem elektrischen Verbraucher ein Risiko dar, so dass hier aufwändige Schutzmaßnahmen zur Abdichtung erforderlich sind.Depending on the type of commercial use, certain requirements are placed on the electrical installations. This includes, for example, protection against moisture or, in case of doubt, protection against gas entry. In the case of electrical installations that require special protection, each coupling point between the conductors or the transfer points on an electrical consumer represents a risk, so that complex protective measures are required for sealing.

Auch wenn der Phasenwähler gemäß DE 10 2012 002 588 A1 eine sehr gute Möglichkeit darstellt, bestehende Elektroinstallationen im Nachhinein hinsichtlich der Phasenbelastung zu konfigurieren, so ist doch gleichzeitig diese Phasenwahleinrichtung gesondert abzudichten, um speziellen Sicherheitsanforderungen gerecht zu werden. Darüber hinaus ist bei jeder Nutzung des Phasenwahlelementes darauf zu achten, die geforderte Dichtigkeit wiederherzustellen.Even if the phase selector according to DE 10 2012 002 588 A1 represents a very good possibility to retrospectively replace existing electrical installations to be configured with regard to the phase load, this phase selection device has to be sealed separately at the same time in order to meet special safety requirements. In addition, every time the phase selection element is used, care must be taken to restore the required tightness.

Aufgabe der Erfindung ist es deshalb, in einem mehrphasigen elektrischen Leitungsstrang die Möglichkeit einer einfachen, nachträglichen Phasenwahl zu ermöglichen und gleichzeitig gesondert zu schützende Koppelpunkte im Leitungsstrang zu minimieren.The object of the invention is therefore to enable the possibility of a simple, subsequent phase selection in a multiphase electrical wiring harness and at the same time to minimize coupling points in the wiring harness that need to be protected separately.

Gelöst wird die Aufgabe von einem Steckverbinder mit den Merkmalen des Anspruches 1, insbesondere mit dessen kennzeichnenden Merkmalen, wonach der Steckfortsatz eine zusätzliche Phasenwahlkammer aufweist, in welcher Phasenkontakte und zumindest ein Versorgungskontakt angeordnet sind und in welcher ein Phasenwahlelement aufgenommen ist.The object is achieved by a connector with the features of claim 1, in particular with its characterizing features, according to which the plug extension has an additional phase selection chamber in which phase contacts and at least one supply contact are arranged and in which a phase selection element is received.

Der wesentliche Vorteil der Erfindung ist darin zu sehen, dass das Phasenwahlelement in einem ohnehin bestehenden und erforderlichen Verbindungselement im Leitungsstrang enthalten ist, der den erforderlichen Normen für die Betriebssicherheit der jeweiligen Elektroinstallation entspricht. Auf ein Zusatzbauteil, beispielsweise ein solches gemäß DE 10 2012 002 588 A1 , welches eine separate Anpassung und Prüfung im Hinblick auf die Schutznormen unterläge, kann verzichtet werden.The main advantage of the invention can be seen in the fact that the phase selection element is contained in an already existing and required connecting element in the wiring harness, which corresponds to the required standards for the operational safety of the respective electrical installation. On an additional component, for example one according to DE 10 2012 002 588 A1 , which would be subject to a separate adaptation and test with regard to the protection standards, can be dispensed with.

Die Elektroinstallation erhält dadurch eine geringere Komplexität und eine höhere Betriebssicherheit.The electrical installation is less complex and more reliable.

Vorgesehen ist ferner, dass die Wand der Phasenwahlkammer eine Kodierkontur aufweist, das Phasenwahlelement eine mit der Kodierkontur zusammenwirkende Kodierstruktur aufweist, das Zusammenwirken von Kodierkontur und Kodierstruktur wenigstens zwei vom Phasenwahlelement wahlweise einnehmbare Positionen bestimmt, in welchen jeweils unterschiedliche Phasenkontakte mit dem Versorgungskontakt verbunden werden.It is also provided that the wall of the phase selection chamber has a coding contour, the phase selection element one with the coding contour having cooperating coding structure, the interaction of coding contour and coding structure determines at least two positions which the phase selection element can selectively assume, in each of which different phase contacts are connected to the supply contact.

Das Zusammenspiel von Kodierkontur und Kodierstruktur gewährleistet nicht nur eine fehlerfreie Kontaktierung bei der Phasenwahl. Es ist darüber hinaus auch Voraussetzung bei einer schlecht zugänglichen Installationssituation, die Phasenwahl blind durchführen zu können.The interaction of the coding contour and the coding structure not only ensures error-free contacting when selecting phases. In addition, it is also a prerequisite for an installation situation that is difficult to access to be able to carry out the phase selection blindly.

Konkret ist vorgesehen, dass die Kodierstruktur der Phasenwahlkammer von Nuten gebildet ist, wohingegen die Kodierstruktur des Phasenwahlelementes von mit den Nuten zusammenwirkenden Stegen gebildet ist.Specifically, it is provided that the coding structure of the phase selection chamber is formed by grooves, whereas the coding structure of the phase selection element is formed by webs that interact with the grooves.

Des Weiteren sieht eine konkrete Ausführungsform vor, dass die Phasenkontakte L1, L2, L3 in der Phasenwahlkammer in einem ersten Raster angeordnet sind, welches für einen zumindest zweiphasige Leiter wenigstens drei nebeneinander angeordnete Felder, bevorzugt jedoch für einen dreiphasigen Leiter sieben nebeneinander angeordnete Felder aufweist, wobei in den zwei ersten Feldern je ein Phasenkontakt L1, L2, L3 einsitzen, das dritte Feld freigehalten ist, im vierten Feld der Versorgungskontakt L einsitzt, die Felder 5 und 6 wiederum freigehalten sind und ein weiterer Phasenkontakt L1, L2, L3 im Feld 7 einsitzt.Furthermore, a specific embodiment provides that the phase contacts L1, L2, L3 are arranged in the phase selection chamber in a first grid which has at least three fields arranged next to one another for an at least two-phase conductor, but preferably seven fields arranged next to one another for a three-phase conductor, where one phase contact L1, L2, L3 is located in each of the first two fields, the third field is kept free, the supply contact L is located in the fourth field, fields 5 and 6 are in turn kept free and another phase contact L1, L2, L3 is in field 7 incarcerated.

Vorgesehen ist ferner, dass das Phasenwahlelement einen Brückenkontakt mit drei Kontaktzungen ausbildet, dass das Phasenwahlelement ein zweites Raster mit zum ersten Raster identischem Rastermaß aufweist und die Kontaktzungen im ersten, dritten und vierten Rasterfeld des zweiten Rasters einsitzen.It is also provided that the phase selection element forms a bridge contact with three contact tongues, that the phase selection element has a second grid with a pitch identical to the first grid, and the contact tongues sit in the first, third and fourth grid field of the second grid.

In einer weiteren Ausführungsform der Erfindung ist vorgesehen, dass das Steckgehäuse und das Buchsengehäuse jeweils Teil eines Koppelelementes eines Leuchtengehäuses einer Linienleuchte sind und an gegenüberliegenden Stirnseiten des Leuchtengehäuses angeordnet sind.In a further embodiment of the invention it is provided that the plug housing and the socket housing are each part of a coupling element of a lamp housing of a line lamp and are arranged on opposite end faces of the lamp housing.

In den Figuren ist ein erfindungsgemäßer Steckverbinder insgesamt mit der Bezugsziffer 10 versehen.In the figures, a plug connector according to the invention is provided overall with the reference number 10.

Der Steckverbinder 10 ist in Figur 1 in seiner Gesamtheit dargestellt. Er verfügt über ein Steckgehäuse 11 und ein Buchsengehäuse 12, die ineinander steckbar sind und so eine mechanische und elektrische Verbindung miteinander eingehen.The connector 10 is in Figure 1 shown in its entirety. It has a plug housing 11 and a socket housing 12, which can be plugged into one another and thus enter into a mechanical and electrical connection with one another.

Das Buchsengehäuse 12 ist lediglich in Figur 1 dargestellt. Es bildet einen Aufnahmeraum aus, in welchem elektrische Kontakte angeordnet sind und welcher der Aufnahme des Steckfortsatzes 13 des Steckgehäuses 11 dient. Der Steckfortsatz 13 oder der Aufnahmeraum kann über geeignete, nicht weiter dargestellte Dichtmittel verfügen, um eine Abdichtung beider Teile gegeneinander entsprechend bestimmter Sicherheitsnormen zu realisieren. Eine solche Abdichtung verhindert insbesondere das Eindringen von Feuchtigkeit oder Gasen in den Steckbereich, in welchem freiliegenden Kontakte angeordnet sind.The socket housing 12 is only in Figure 1 shown. It forms a receiving space in which electrical contacts are arranged and which is used to receive the plug-in extension 13 of the plug-in housing 11. The plug-in extension 13 or the receiving space can have suitable sealing means, not shown, in order to seal both To realize parts against each other according to certain safety standards. Such a seal prevents in particular the penetration of moisture or gases into the plug-in area in which exposed contacts are arranged.

Für die Erfindung wesentlich ist insbesondere das in Figur 2 und 3 dargestellte Steckgehäuse 11. Dessen Steckfortsatz 13 bildet zunächst Kammern 14 und 15 aus, in welchen Steckkontakte 16 angeordnet sind. Diese Steckkontakte 16 dienen der elektrischen Verbindung von Leitungssträngen.What is particularly important for the invention is that in Figure 2 and 3 illustrated plug housing 11. Its plug extension 13 initially forms chambers 14 and 15 in which plug contacts 16 are arranged. These plug contacts 16 are used for the electrical connection of cable strands.

Zusätzlich verfügt das Steckgehäuse 11 in seinem Steckfortsatz 13 über eine sogenannte Phasenwahlkammer 17. In dieser sind Kontakte L1, L2, L3 als sogenannte Phasenkontakte angeordnet. Zusätzlich hält die Phasenwahlkammer 17 einen sogenannten Versorgungskontakt L bereit.In addition, the plug-in housing 11 has a so-called phase selection chamber 17 in its plug-in extension 13. In this, contacts L1, L2, L3 are arranged as so-called phase contacts. In addition, the phase selection chamber 17 has a so-called supply contact L ready.

In die Phasenwahlkammer 17 ist darüber hinaus das Phasenwahlelement 18 einsetzbar. In das Phasenwahlelement 12 ist ein Isolierstoffteil, welches einen Brückenkontakt 19 trägt. Dieser Brückenkontakt 19 verfügt über drei Kontaktzungen 20, 21 und 22.In addition, the phase selection element 18 can be inserted into the phase selection chamber 17. In the phase selection element 12 there is an insulating material which carries a bridge contact 19. This bridge contact 19 has three contact tongues 20, 21 and 22.

Darüber hinaus bildet die Wand 23 der Phasenwahlkammer 17 eine Kodierkontur 24 in Form von nicht näher bezeichneten Nuten aus. Diese Kodierkontur 24 wirkt mit einer Kodierstruktur 25 des Phasenwahlelementes 18 zusammen, die von nicht näher bezeichneten Stegen gebildet ist.In addition, the wall 23 of the phase selection chamber 17 forms a coding contour 24 in the form of unspecified grooves. This coding contour 24 interacts with a coding structure 25 of the phase selection element 18, which is formed by webs that are not designated in any more detail.

Nachfolgend wird ein Ausführungsbeispiel mit einem gängigen, dreiphasigen Leiter bzw. einer dreiphasigen Durchgangsverdrahtung beschrieben. Die Erfindung lässt sich jedoch auch auf Leiter mit lediglich zwei Phasen oder mehr als drei Phasen anwenden.An exemplary embodiment with a common three-phase conductor or three-phase through wiring is described below. However, the invention can also be applied to conductors with only two phases or more than three phases.

Kodierstruktur 25 und Kodierkontur 24 sind derart ausgebildet, dass im hier vorliegenden Ausführungsbeispiel das Phasenwahlelement 18 in drei unterschiedlichen, eindeutigen Positionen in der Phasenwahlkammer 17 aufgenommen werden kann. In jeder der drei Positionen verbindet der Brückenkontakt 19 des Phasenwahlelementes 18 den Versorgungskontakt L mit einem der Phasenkontakte L1, L2 oder L3. Je nach Anordnung des Phasenwahlelementes 18 in einer der drei Positionen in der Phasenwahlkammer 17 lässt sich der am Versorgungskontakt L angebundene elektrische Verbraucher, insbesondere eine nicht weiter dargestellte Leuchte, über eine der drei Phasen L1, L2 oder L3 speisen.The coding structure 25 and the coding contour 24 are designed in such a way that, in the present exemplary embodiment, the phase selection element 18 can be accommodated in three different, unique positions in the phase selection chamber 17. In each of the three positions, the bridge contact 19 of the phase selection element 18 connects the supply contact L to one of the phase contacts L1, L2 or L3. Depending on the arrangement of the phase selection element 18 in one of the three positions in the phase selection chamber 17, the electrical consumer connected to the supply contact L, in particular a lamp (not shown), can be fed via one of the three phases L1, L2 or L3.

Bei einem zweiphasigen Leiter genügt es, zwei Positionen für das Phasenwahlelement 18 über die Kodierkontur 24 und die Kodierstruktur 25 zu definieren. Weist die Durchgangsverdrahtung mehr als 3 Phasen auf, werden entsprechend mehr Positionen für das Phasenwahlelement definiert.In the case of a two-phase conductor, it is sufficient to define two positions for the phase selection element 18 via the coding contour 24 and the coding structure 25. If the through wiring has more than 3 phases, more positions are defined for the phase selection element accordingly.

Die Phasenwahlkammer 17 weist sieben nebeneinander, in einem definierten Rastermaß angeordnete Kontaktkammern auf. Zwei Phasenkontakte L2 und L3 sind nebeneinander in den ersten beiden Rasterfeldern 1 und 2 eingesetzt. Das danebenliegende Rasterfeld 3 ist frei gehalten. Im Rasterfeld 4 folgt der Versorgungskontakt L. Daneben sind die zwei Rasterfelder 5 und 6 freigehalten. Der letzte Phasenkontakt L1 sitzt im siebten Rasterfeld. Eine zweiphasige Durchgangsverdrahtung fordert wenigstens 3 Kontaktkammern mit einer entsprechenden Kontaktbestückung. Für mehr als drei Phasen ist eine höhere Anzahl an Kontaktkammern erforderlich.The phase selection chamber 17 has seven contact chambers arranged next to one another in a defined grid dimension. Two phase contacts L2 and L3 are used next to one another in the first two grid fields 1 and 2. The adjacent grid field 3 is kept free. The supply contact L follows in the grid field 4. In addition, the two grid fields 5 and 6 are kept free. The last phase contact L1 is in the seventh grid field. A two-phase through-wiring requires at least 3 contact chambers with a corresponding number of contacts. A higher number of contact chambers is required for more than three phases.

Das Phasenwahlelement 18 verfügt ebenfalls über Kontaktkammern, über welche die Kontaktzungen 20, 21 und 22 des Brückenkontakts 13 ausgeführt werden. Diese Kontaktkammern sind im selben Rastermaß voneinander beabstandet, welches den Kontaktkammern in der Phasenwahlkammer 17 zugrunde liegt. Im Phasenwahlelement 18 sind vier Kontaktkammern vorgehalten, wobei die erste Kontaktzunge 20 in der ersten Kontaktkammer einliegt, die danebenliegende Kontaktkammer freigehalten ist und die Kontaktkammern 3 und 4 jeweils wieder mit einer Kontaktzunge 21 und 22 bestückt sind. Auf diese Weise der Anordnungen der Phasenkontakte L1, L2, L3 sowie der Kontaktzungen 20, 21, 22 ist es möglich, mit drei Einschubpositionen auf vergleichsweise kleinem Raum die Wahl von drei unterschiedlichen Phasen zu ermöglichen. Bei einer zweiphasigen Leitung reicht ein Brückenkontakt mit zwei Kontaktzungen. Eine Durchgangsverdrahtung mit mehr als drei Phasen erfordert eine Anpassung zumindest in der Belegung der Kontaktkammern bzw. des Rasters des Brückenkontaktes 13.The phase selection element 18 also has contact chambers via which the contact tongues 20, 21 and 22 of the bridge contact 13 are carried out. These contact chambers are spaced from one another in the same grid dimension, which the contact chambers in the Phase selection chamber 17 is based. Four contact chambers are provided in the phase selection element 18, the first contact tongue 20 lying in the first contact chamber, the adjacent contact chamber being kept free and the contact chambers 3 and 4 each again being equipped with a contact tongue 21 and 22. In this way of the arrangements of the phase contacts L1, L2, L3 and the contact tongues 20, 21, 22, it is possible to select three different phases with three insertion positions in a comparatively small space. With a two-phase line, a bridge contact with two contact blades is sufficient. Through wiring with more than three phases requires an adaptation at least in the assignment of the contact chambers or the grid of the bridge contact 13.

Schließlich ist die Tiefe des Phasenwahlelementes 18 derart abgestimmt, dass es mit einem Widerlager 26, welches im bevorzugten Ausführungsbeispiel gleichzeitig als Betätigungshandhabe dient, bei gestecktem Steckverbinder 10 auf dem Boden des Buchsengehäuses 12 anliegt und so in seinem einen Phasenkontakt L1, L2, L3 und den Versorgungskontakt L kontaktierenden Steckzustand gehalten wird. Ein Lösen des Phasenwahlelementes 18 oder eine aufgrund nicht korrekter Einstecktiefe schlechte Kontaktierung wird auf diese Weise sicher vermieden.Finally, the depth of the phase selection element 18 is coordinated such that it rests with an abutment 26, which in the preferred exemplary embodiment also serves as an actuating handle, on the bottom of the socket housing 12 when the plug connector 10 is inserted and so in its one phase contact L1, L2, L3 and the Supply contact L contacting plugged state is held. A loosening of the phase selection element 18 or poor contacting due to incorrect insertion depth is reliably avoided in this way.

Es ist vorgesehen, dass das Steckgehäuse 11 einerseits und das Buchsengehäuse 12 andererseits stirnseitige Verschluss- bzw. Koppelbauteile einer Linienleuchte bilden. So lassen sich mehrere Linienleuchten mechanisch und elektrisch durch zusammenstecken von Steckgehäuse 11 und Buchsengehäuse 12 untereinander verbinden, was die Verdrahtung erheblich vereinfacht.It is provided that the plug housing 11, on the one hand, and the socket housing 12, on the other hand, form end-face closure or coupling components of a line light. Several line lights can be connected to one another mechanically and electrically by plugging the plug housing 11 and socket housing 12 together, which considerably simplifies the wiring.

Das Buchsengehäuse 12 und das Steckgehäuse 11 sind vorteilhafter Weise gegenüber dem Leuchtengehäuse gegen Fremdkörper, Feuchtigkeit und/ oder Gasen abgedichtet, um entsprechende Schutznormen zu erfüllen.The socket housing 12 and the plug housing 11 are advantageous compared to the lamp housing against foreign bodies, Sealed moisture and / or gases to meet appropriate protection standards.

Für die Einspeisung von Elektrizität existiert ein nicht naher dargestelltes Einspeiseelement, welches zur Kopplung mit dem Steckgehäuse 11 oder dem Buchsengehäuse 12 angepasst ist und die elektrische Verbindung zur Elektroinstallation des Gebäudes herstellt. Um das an dem dem Einspeiseelement abgewandten Ende der Leuchteninstallation sicher zu verschließen, existiert eine ebenfalls nicht dargestellte Endkappe. Auch diese ist entweder zur Kopplung mit dem Buchsengehäuse 12 oder dem Steckgehäuse 11 ausgebildet. Sowohl das Einspeiseelement wie auch die Endkappe können über eine Dichtung gegen Fremdkörper, Feuchtigkeit und/oder Gase verfügen.For the supply of electricity, there is a feed element, not shown in detail, which is adapted for coupling with the plug housing 11 or the socket housing 12 and establishes the electrical connection to the electrical installation of the building. In order to securely close the end of the luminaire installation facing away from the feed element, there is an end cap, also not shown. This is also designed either for coupling with the socket housing 12 or the plug housing 11. Both the feed element and the end cap can have a seal against foreign bodies, moisture and / or gases.
