Description

Die Erfindung betrifft eine Steckerverbindungsanordnung für feuchtigkeitsgeschützte elektrische Steckverbindungen.The invention relates to a connector connection arrangement for moisture-proof electrical connectors.

Ein Stecker für derartige Steckerverbindungsanordnungen ist aus der DE 197 37 884 A1 bekannt. Dabei bildet das elastische Dichtelement den Steckerkopf aus, in dem die elektrischen Kontakte über eine spezielle Führung geführt und gelagert sind. Je nachdem, welche Art von Stecker hergestellt werden soll und wie dementsprechend die elektrischen Kontakte angeordnet sind, werden unterschiedliche Dichtelemente und unterschiedliche Führungen benötigt. Da das Dichtelement bei den vorbekannten Steckern Hauptbauteil ist, müssen eine Vielzahl unterschiedlicher Teile auf Lager gehalten werden, um verschiedene Steckervarianten zu bauen.A connector for such connector connection arrangements is known from DE 197 37 884 A1 known. In this case, the elastic sealing element forms the plug head, in which the electrical contacts are guided and supported by a special guide. Depending on which type of plug is to be produced and how accordingly the electrical contacts are arranged, different sealing elements and different guides are required. Since the sealing element is the main component in the prior art plugs, a variety of different parts must be kept in stock to build different connector types.

Derartige Steckersysteme werden insbesondere für die Steuerung von komplexen Wasserspielen verwendet und müssen daher eine hohe Anforderung an Dichtigkeit aufweisen. Bevorzugt sollen diese sogar der Klasse IP68 genügen und unter Wasser einsetzbar sein.Such connector systems are used in particular for the control of complex water features and must therefore have a high requirement for tightness. Preferably, these should even meet the IP68 class and be usable underwater.

Aus der EP 1 239 549 A ist eine Steckverbindungsanordnung für feuchtigkeitsgeschützte elektrische Steckverbindungen bekannt, wobei ein Stecker mit einem Grundkörper mit ein rückseitig heraustretendem Leitungskabel und mit elektrische Kontakte aufnehmendem Kontaktträger in eine Muffe einzusetzen ist, die einen Befestigungsflansch mit Verschraubungslöchern und einer Ringdichtung als Wanddurchführung in einer Wandöffnung aufweist.From the EP 1 239 549 A a connector assembly for moisture-proof electrical connectors is known, wherein a plug having a base body with a back herausetretendem cable and with electrical contacts receiving contact carrier is to be inserted into a sleeve having a mounting flange with screw holes and a ring seal as a wall bushing in a wall opening.

Der Erfindung liegt daher die Aufgabe zugrunde, eine vorbekannte Steckerverbindungsanordnung derart zu verbessern, dass bei optimierter Dichtigkeit der Herstellungsaufwand verringert wird. Diese Aufgabe wird erfindungsgemäß durch eine Steckerverbindungsanordnung mit den Merkmalen des Anspruchs 1 gelöst.The invention is therefore based on the object to improve a previously known connector connection arrangement such that with optimized tightness of the manufacturing cost is reduced. This object is achieved by a connector connection arrangement with the features of claim 1.

Durch das formschlüssige Einsetzen eines die elektrischen Kontakte aufnehmenden Kontaktträgers in den Grundkörper wird der Kontaktträger, neben den elektrischen Kontakten selbst, variierbares Bauelement des Steckers bei verschiedenen Steckervarianten. Auch können sich der Grundkörper und die elektrischen Kontakte wegen der formschlüssigen Führung nicht zueinander verschieben, so dass derartige Stecker mit hoher Präzision herstellbar sind. Bevorzugt sind dabei sowohl der Grundkörper als auch der Kontaktträger aus einem starren Material, insbesondere Hartkunststoff, gefertigt, die eine exakte Positionierung aneinander sicherstellen.By the positive insertion of the electrical contacts receiving contact carrier in the body of the contact carrier, in addition to the electrical contacts themselves, variable component of the plug in different connector variants. Also, the base body and the electrical contacts can not move to each other because of the positive guide, so that such connectors can be produced with high precision. Both the base body and the contact carrier are preferably made of a rigid material, in particular hard plastic, which ensure exact positioning to one another.

Neben den Steckern der DE 197 37 884 A1 sind aus der Praxis Stecker bekannt, die mit einem starren Flansch über Schraubverbindungen gegen das umlaufende Areal einer Steckerbuchse gepresst werden. An der Steckerbuchse ist dazu eine Dichtung angeklebt. Diese Verbindung kann eine gute Dichtigkeit erreichen, ist jedoch nicht fehlbedienungssicher, da je nach Anziehen der Schraubverbindung der Stecker verkantet oder gekippt werden kann. Wird eine Seite der Verschraubung zu eng angezogen, entsteht an der flexiblen Dichtung zwangsläufig auf der gegenüberliegenden Seite ein Spalt, der zu Undichtigkeiten führt.In addition to the plugs of DE 197 37 884 A1 are known from practice plug, which are pressed with a rigid flange via screw against the peripheral areal of a socket. A gasket is glued to the socket. This connection can achieve good tightness, but is not safe to misuse, since depending on the tightening of the screw, the plug can be tilted or tilted. If one side of the screw connection is tightened too tightly, a gap will inevitably form on the flexible seal on the opposite side, which leads to leaks.

Der erfindungsgemäße Stecker schafft demgegenüber Abhilfe, indem der Befestigungsflansch einen starren Anlagebereich zur Anlage an einer Steckerbuchse aufweist und das Dichtelement eine Flächendichtung und auf einer Teilfläche davon eine erhöhte Formdichtung hat. Das Dichtelement ist dabei bevorzugt so auszubilden, dass die Flächendichtung im unverbundenen Zustand des Steckers mit der Steckerbuchse den Anlagebereich des Grundkörpers geringfügig überragt. Beim Einstecken des Steckers in die Steckerbuchse und der Verspannung dieser gegenüber durch eine Verschraubung, wird das Dichtelement mit seiner Flächendichtung dann soweit gequetscht, dass der Anlagebereich des Befestigungsflansches an der Steckerbuchse zur Anlage kommt. Die erhöhte Formdichtung wird dabei noch stärker gequetscht und stellt die absolute Dichtigkeit sicher. Die Formdichtung erstreckt sich daher vollständig um die elektrischen Kontakte herum. In einer weiter bevorzugten Ausführungsform hat der Grundkörper an der Rückseite des Dichtelementes einen etwa der Form der Formdichtung entsprechenden Vorsprung, so dass gerade auf den Bereich der Formdichtung ein erhöhter Druck ausgeübt wird.The connector according to the invention provides a remedy by the mounting flange has a rigid contact area for abutment with a socket and the sealing element has a surface seal and on a partial surface thereof has an increased seal shape. The Sealing element is preferably designed so that the surface seal in the unconnected state of the plug with the socket slightly beyond the contact area of the body. When inserting the plug into the socket and the tension of this opposite by a screw, the sealing element is then squeezed with its surface seal so far that the contact area of the mounting flange comes to rest on the socket. The raised seal is even more squeezed and ensures the absolute tightness. The molded gasket therefore extends completely around the electrical contacts. In a further preferred embodiment, the base body at the rear side of the sealing element has a projection which corresponds approximately to the shape of the molded seal, so that an increased pressure is exerted precisely on the area of the molded seal.

Es ist weiter von Vorteil, wenn das Dichtelement lösbar am Grundkörper festgelegt ist. Da das Dichtelement dem höchsten Verschleiß unterliegt, kann dieses dann unproblematisch getauscht werden, ohne dass der ganze Stecker unbrauchbar wird.It is also advantageous if the sealing element is releasably fixed to the base body. Since the sealing element is subject to the highest wear, this can then be easily replaced without the whole plug is unusable.

Insgesamt lässt sich eine besonders gute Dichtigkeit des Steckers erreichen, wenn dieser im Grundkörper einen Hohlraum aufweist, der komplett mit einer Vergussmasse gefüllt wird. Dadurch wird eine Kapilarsperre erreicht. Dies ist insbesondere mit einer dünnflüssigen Vergussmasse möglich, die bevorzugt über eine vorderseitige Öffnung des Kontaktträgers in den Hohlraum des Grundkörpers eingefüllt werden kann, wozu die Öffnung des Kontaktträgers sich bis in diesen Hohlraum hinein erstrecken muss. Damit die Vergussmasse nicht am hinteren Ende aus dem Stecker wieder herausläuft und keine vorherige Sicherung mit einer dickflüssigen Verguss masse von hinten nötig ist, hat der Stecker eine rückseitige Dichtung im Austrittsbereich des Leitungskabels, die das Leitungskabel umschließt. Diese rückseitige Dichtung kann vorzugsweise konisch ausgeformt sein und von hinten in den Grundkörper hineingedrückt sein. Sie sollte ebenfalls aus einem elastischen Material bestehen.Overall, a particularly good tightness of the plug can be achieved if it has a cavity in the main body, which is completely filled with a potting compound. This achieves a capillary lock. This is possible, in particular, with a low-viscosity potting compound, which can preferably be introduced into the cavity of the base body via a front-side opening of the contact carrier, for which purpose the opening of the contact carrier must extend into this cavity. Thus, the potting compound does not run out of the plug at the rear end and no previous backup with a thick grout mass from the rear, the plug has a rear seal in the exit area of the cable which surrounds the cable. This rear seal may preferably be formed conical and be pressed from behind into the body. It should also be made of an elastic material.

Bei bevorzugten Ausführungsformen hat der Kontaktträger einen oder mehrere Kodierungsvorsprünge und/oder Kodierungsausnehmungen, die mit entsprechenden Vorsprüngen oder Ausnehmungen der jeweiligen Steckerbuchse zusammenwirken. Dadurch können verschiedene Leistungsstecker oder auch verschiedene Steuerstecker unterschieden werden, und es wird vermieden, dass Fehlbenutzungen auftreten. Insbesondere werden dadurch bei der Spannungsversorgung Verpolungen vermieden.In preferred embodiments, the contact carrier has one or more coding projections and / or coding recesses which cooperate with corresponding projections or recesses of the respective socket. As a result, different power connectors or different control connectors can be distinguished, and it is avoided that misuse occurs. In particular, reverse polarity is thereby avoided in the power supply.

Zur Vereinfachung der Montage des Steckers, bevor dieser vergossen wird, ist es vorteilhaft, den Kontaktträger mit zumindest einem Führungsvorsprung zu versehen, wodurch dieses sicher geführt in den Grundkörper eingesetzt werden kann. Auch ein Auflageflansch des Kontaktträgers ist sinnvoll, mit dem dieses an einem definierten Anschlag des Grundkörpers zur Auflage kommt, so dass stets bei der Montage eine exakte Positionierung der elektrischen Kontakte erfolgt.To simplify the assembly of the plug before it is cast, it is advantageous to provide the contact carrier with at least one guide projection, whereby this can be safely inserted into the base body. Also, a support flange of the contact carrier is useful, with this comes to rest on a defined stop of the body, so that there is always an exact positioning of the electrical contacts during assembly.

Die Erfindung befasst sich auch mit einer Steckerverbindungsanordnung, die einen elektrischen Verteiler aufweist, wobei dieser Verteiler dadurch gekennzeichnet ist, dass er zumindest mit einem elektrischen Leitungskabel fest verbunden ist, an dessen Ende sich ein vorbeschriebener erfinderischer Stecker befindet.The invention is also concerned with a plug connection arrangement comprising an electrical distributor, this distributor being characterized in that it is fixedly connected at least to an electric cable, at the end of which there is a previously described inventive plug.

In der Praxis sind bisher lediglich so genannte Verteiler- oder Verbindungsboxen im Einsatz, die entweder mit separaten Kabeln und Steckern verbunden werden, wobei an den Verbindungsstellen Undichtigkeiten auftreten können oder bei denen die Kabel vor Ort in der Verteilerbox angeklemmt werden müssen, was zu Fehlern bei der Montage führen kann. Zudem war die Ausfallwahrscheinlichkeit durch Undichtigkeiten bei dem Verschließen der Verteilerboxen sehr hoch. Das wird durch den erfindungsgemäßen Verteiler mit festem Kabel und Stecker vermieden. Bevorzugt ist der erfindungsgemäße Verteiler ebenfalls komplett vergossen, so das eine absolute Dichtigkeit gewährleistet ist.In practice, so far only so-called distribution or connection boxes are used, which are connected either with separate cables and plugs, which can occur at the joints leaks or where the cables must be clamped in place in the distribution box, resulting in errors can lead to the assembly. In addition, the probability of failure due to leaks in closing the distribution boxes was very high. This is avoided by the inventive distributor with a fixed cable and plug. Preferably, the distributor according to the invention is also completely encapsulated, so that an absolute tightness is guaranteed.

Bevorzugt ist eine Steckerverbindungsanordnung aus Verteilern mit zwei fest verbundenen Leitungskabeln aufgebaut, bei denen eines der Leitungskabel ein Leistungskabel mit Leistungsstecker für die Stromversorgung ist und das andere ein Steuerkabel mit Steuerkontaktstecker für die Steuerung des Systems, insbesondere durch ein BUS-System. Mehrere derartiger Verteiler können dadurch in Reihe geschaltet werden, wobei sowohl die Energieversorgung als auch die Steuersignale durch die einzelnen Verteiler zu dem jeweils nächsten durchgeschleift werden. Jeder Verteiler kann dann einen entsprechenden Verbraucher, beispielsweise eine Pumpe, eine Wasserspieldüse oder dergleichen steuern.Preferably, a connector assembly is constructed of distributors with two fixed line cables in which one of the cable is a power cable with power connector for the power supply and the other a control cable with control connector for the control of the system, in particular by a bus system. Several such distributors can thereby be connected in series, with both the power supply and the control signals being looped through the individual distributors to the next. Each distributor can then control a corresponding consumer, for example a pump, a water nozzle or the like.

Der in den Fig. 1 und 2 dargestellte Stecker hat einen Grundkörper 1, aus dem rückseitig ein ummanteltes elektrisches Leitungskabel 2 herausführt. Die Abdichtung an der Rückseite erfolgt durch einen elastischen Dichtstopfen 3. Der Grundkörper hat vorderseitig einen Befestigungsflansch 4. In dem Grundkörper ist ein Kontaktträger 5 bzw. Steckereinsatz formschlüssig eingesetzt. Der Kontaktträger 5 trägt die elektrischen Kontaktstifte 6, die mit dem Leitungskabel 2 verbunden sind.The in the Fig. 1 and 2 shown plug has a base body 1, leading out of the back of a sheathed electrical cable 2. The seal on the back is made by an elastic sealing plug 3. The main body has front side a mounting flange 4. In the main body is a contact carrier 5 or plug insert used positively. The contact carrier 5 carries the electrical contact pins 6, which are connected to the cable 2.

Der Befestigungsflansch 4 hat einen starren Anlagebereich 14 zur Anlage an einer Steckerbuchse, wie später noch anhand Fig. 4 beschrieben wird. Am Befestigungsflansch 4 bzw. in diesem ist ein elastisches Dichtelement 7 aufgenommen, das eine Flächendichtung 17 und eine nach vorne hervorspringende erhöhte Formdichtung 27 aufweist.The mounting flange 4 has a rigid contact region 14 for engagement with a socket, as later still with reference Fig. 4 is described. On the mounting flange 4 and in this an elastic sealing element 7 is added, which has a surface seal 17 and a protruding forward increased molded seal 27.

Die Montage der erfindungsgemäßen Stecker wird anhand Fig. 3 beschrieben. Dazu wird der Kontaktträger 5 mit den elektrischen Kontakten 6 und dem Leitungskabel 2 versehen und in den Grundkörper 1 eingeführt. Dazu hat der Kontaktträger wie dargestellt bevorzugt Führungsvorsprünge 15, die das exakte Einführen in eine entsprechende Öffnung des Grundkörpers 1 erleichtern. Außerdem hat das Kontaktelement 5 einen umlaufenden Auflageflansch 25, der im Montagezustand an einem definierten Anschlag 11 des Grundkörpers 1 zur Anlage gelangt. Damit ist der Kontaktträger 5 exakt positioniert. Der Flansch 25 ist bevorzugt nicht kreisringförmig, sondern an zwei Seitenbereichen abgeflacht, so dass Stecker mit einem geringeren Platzbedarf verwendet werden können und mehrere Stecker auf einfache Weise in einer Mehrfachbuchse nebeneinander montierbar sind. (Siehe Fig. 7.)The assembly of the plug according to the invention is based on Fig. 3 described. For this purpose, the contact carrier 5 is provided with the electrical contacts 6 and the cable 2 and introduced into the base body 1. For this purpose, the contact carrier has as shown preferably guide projections 15, which facilitate the exact insertion into a corresponding opening of the base body 1. In addition, the contact element 5 has a peripheral support flange 25, which comes to rest in the assembled state at a defined stop 11 of the base body 1. Thus, the contact carrier 5 is positioned exactly. The flange 25 is preferably not annular, but flattened on two side areas, so that plugs can be used with a smaller footprint and several plugs are mounted side by side in a simple manner in a multiple jack in a simple manner. (Please refer Fig. 7 .)

Nun wird das in Fig. 3 nicht dargestellte Leitungskabel 2 hindurchgeführt und die Dichtung 3 in die Rückseite des Grundkörpers hineingedrückt. Der Grundkörper ist damit rückwärtig verschlossen. Von der Vorderseite / Oberseite aus kann dann durch eine dafür vorgesehene Öffnung 35 - siehe Fig. 2 - in den inneren Hohlraum des Grundkörpers 1 Vergussmasse 8 hineingefüllt werden, wodurch eine Kapilarwirkung entlang des Leitungskabels 2 und der elektrischen Kontakte 6 und Undichtigkeiten vermieden werden.Now that will be in Fig. 3 not shown line cable 2 passed and the seal 3 is pressed into the back of the body. The body is thus closed back. From the front / top can then through a designated opening 35 - see Fig. 2 - Be poured into the inner cavity of the base body 1 potting compound 8, whereby a capillary action along the cable 2 and the electrical contacts 6 and leaks are avoided.

Zur Abdichtung gegenüber einer Steckerbuchse wird die Vorderseite des Grundkörpers mit dem elastischen Dichtelement 7 versehen, das an dem Grundkörper 1 vorzugsweise nicht verklebt, sondern lediglich in diesen hineingesteckt wird. Auf diese Weise kann das dem größten Verschleiß unterliegende elastische Dichtelement 7 jederzeit ohne großen Aufwand ausgetauscht werden.For sealing against a socket, the front of the body is provided with the elastic sealing element 7, which is preferably not glued to the base body 1, but merely inserted into this. In this way, the greatest wear underlying elastic sealing element 7 can be replaced at any time without much effort.

Fig. 3 zeigt exemplarisch vier verschiedene Varianten von Kontaktträgern 5. Diese haben jeweils Kodierungsvorsprünge 45 oder Kodierungsausnehmungen 55. Diese dienen in Zusammenwirkung mit entsprechenden nicht dargestellten Gegenausnehmungen oder Gegenvorsprüngen in den jeweiligen Steckerbuchsen dazu, dass die Stecker nur in die für sie passenden und zugehörigen Buchsen eingesetzt werden können. Fig. 3 shows exemplarily four different variants of contact carriers 5. These have each coding projections 45 or Codierungsausnehmungen 55. These serve in conjunction with corresponding counter-recesses not shown or counter-projections in the respective sockets to ensure that the plug can only be used in the appropriate for them and associated sockets ,

Fig. 4 zeigt den Stecker aus Fig. 2, eingesteckt in eine Steckerbuchse 9. Dabei ist der Kontaktträger 5 mit seinen elektrischen Kontaktsteckern 6 in eine entsprechende Aufnahme 19 der Steckerbuchse 9 eingeführt. Der Befestigungsflansch 4 des Steckergrundkörpers 1 kommt mit seinem starren Anlagebereich 14 in Kontakt mit einer Anlagefläche 10 der Steckerbuchse 9. Zur Befestigung durchgreifen nicht dargestellte Schrauben Verschraubungsausnehmungen 24 des Befestigungsflansches 4 und greifen in Gewinde 29 der Steckerbuchse 9 ein. Dabei wird die im nicht eingesteckten Zustand gemäß Fig. 1 über den starren Anlagebereich 14 des Befestigungsflansches 4 geringfügig vorstehende Flächendichtung 17 zusammengedrückt, so dass der starre Anlagebereich 14 fest an der Anlagefläche 10 anliegt. Ebenfalls zusammengedrückt wird die vorstehende Formdichtung 27, die dadurch eine absolut wasserdichte Abdichtung im Übergangsbereich zwischen Stecker und Steckerbuchse 9 schafft. Dies wird noch verstärkt, wenn der Grundkörper 1 wie bevorzugt und in Fig. 3 zu sehen an seiner den Dichtelement 7 zugewandten Vorderseite einen der Form der Formdichtung 27 folgenden Vorsprung 31 aufweist, durch den Formdichtung 27 noch fester angepresst wird. Auch wenn die Befestigungsverschraubung ungleichmäßig oder einseitig zu fest angezogen wird, kann dabei wegen des starren Anlagebereiches 14 kein Verkanten des Steckers und keine daraus resultierende Undichtigkeit erfolgen. Fig. 4 shows the plug Fig. 2 Inserted into a socket 9. In this case, the contact carrier 5 is inserted with its electrical contact plugs 6 in a corresponding receptacle 19 of the female connector 9. The fastening flange 4 of the connector base body 1 comes with its rigid contact area 14 in contact with a contact surface 10 of the socket 9. For fastening pass through screws not shown Verschraubungsausnehmungen 24 of the mounting flange 4 and engage in thread 29 of the female connector 9 a. In this case, the not plugged in accordance with Fig. 1 4 slightly protruding surface seal 17 is compressed over the rigid contact region 14 of the mounting flange, so that the rigid contact region 14 rests firmly against the contact surface 10. Also compressed is the protruding molded seal 27, which thereby forms an absolutely watertight seal in the transition region between plug and socket 9 creates. This is further enhanced when the base body 1 as preferred and in Fig. 3 to see at its the sealing element 7 facing the front of the shape of the molded seal 27 following projection 31, is pressed even more firmly by the molded seal 27. Even if the Befestigungsverschraubung unevenly or unilaterally tightened too tight, it can be done because of the rigid contact area 14 no jamming of the plug and no resulting leakage.

Fig. 5 zeigt eine Draufsicht auf die Steckerbuchse 9 ohne eingesteckten Stecker und Fig. 6 einen Schnitt durch den Gegenstand aus Fig. 5, ebenfalls ohne Stecker. In Fig. 7 ist eine anders gestaltete Anlagefläche 10' gezeigt, die gleichzeitig vier Steckerbuchsen übergreift. Fig. 5 shows a plan view of the female connector 9 without plug and plug Fig. 6 make a cut through the object Fig. 5 , also without plug. In Fig. 7 a differently shaped contact surface 10 'is shown, which simultaneously engages over four sockets.

Fig. 8 zeigt die Vorder- und Rückansicht eines elektrischen Verteilers bzw. einer Verteiler- oder Verbindungsbox 12. Diese hat auf der Vorderseite eine Eingangsbuchse 9', in die der Stecker aus Fig. 1 hineingesteckt werden kann, und auf der Vorder- und der Rückseite je eine Ausgangsbuchse 9". Die Verteiler- bzw. Verbindungsbox 12 ist bevorzugt als wasserdichte Einheit komplett vergossen. Da über die erfindungsgemäßen Stecker auf einfache Weise absolut wasserdichte elektrische Verbindungen geschaffen werden können, ist es bei den erfindungsgemäßen entsprechenden Boxen 12 nicht nötig, Öffnungen vorzusehen, bei denen Kabel vor Ort montiert und angeklemmt werden, wie es bei vorbekannten Verteiler- oder Verbindungssystemen der Fall ist. Die in Fig. 8 dargestellte Box 12 dient der Aufnahme und Weiterleitung von elektrischen Steuerspannungen. Diese werden in die Box 12 über die Eingangsbuchse 9' eingespeist und verlassen sie über die rückseitige Ausgangsbuchse 9" zu einem daran angeschlossenen Gerät, beispielsweise zu einer Pumpe oder einem Wasserspiel. Über die weitere, vorderseitige Ausgangsbuchse 9" können Signale durchgeschleift und an eine sich daran anschließende weitere Verteilerbox weitergeleitet werden. Diese Steuerung kann bevorzugt über einen DatenBUS erfolgen. Fig. 8 shows the front and rear view of an electrical distributor or a distribution or junction box 12. This has on the front of an input jack 9 ', in which the plug Fig. 1 The distribution or connection box 12 is preferably completely encapsulated as a watertight unit, since absolutely watertight electrical connections can be created via the plugs according to the invention in a simple manner In the case of the corresponding boxes 12 according to the invention, it is not necessary to provide openings in which cables are mounted and clamped on site, as is the case in previously known distribution or connection systems Fig. 8 illustrated box 12 serves to receive and forward electrical control voltages. These are fed into the box 12 via the input socket 9 'and leave via the rear output socket 9 "to a device connected to it, for example to a pump or a water feature." Via the further, front-side output socket 9 ", signals can be looped through and forwarded to a further distributor box connected thereto. This control can preferably take place via a DatenBUS.

Fig. 9 zeigt schematisch wie derartige Verteiler 12 in Reihe geschaltet werden können, zur Leistungsversorgung oder Steuerung z.B. verschiedener Düsen 20. In Fig. 9a ist nur eine dieser Ketten dargestellt, während Fig. 9b den Anschluss der Geräte 20 über zwei Ketten von Verteilerboxen 12 zeigt, von denen eine der Leistungsversorgung und die andere der Steuerung dient. Fig. 9 schematically shows how such distributors 12 can be connected in series, for power supply or control, for example, various nozzles 20. In Fig. 9a only one of these chains is shown while Fig. 9b shows the connection of the devices 20 via two chains of distribution boxes 12, one of which serves the power supply and the other the control.

Die Abnehmergeräte 20 sind dazu bevorzugt mit zwei fest mit den Geräten 20 verbundenen Kabeln 21 und zwei erfindungsgemäßen Steckern 22 versehen, die jeweils in eine Steckerbuchse 8 der Verteilerbox 12 eingesteckt und dort durch die besondere Ausgestaltung wasserdicht fixiert werden.The pickup devices 20 are preferably provided with two fixedly connected to the devices 20 cables 21 and two connectors 22 according to the invention, each plugged into a socket 8 of the distribution box 12 and there are waterproof fixed by the particular design.

Die erfindungsgemäße Steckerverbindungsanordnung eignet sich auf besondere Weise zur flexiblen Gestaltung von Wasserspielen, wobei die entsprechenden Stecker in großer Varianz kostengünstig herstellbar sind und in Verbindung mit dem elektrischen Verteiler 12, 13 eine leicht montierbare und wasserdichte Einheit bilden, die extrem wenig störanfällig ist.The connector assembly according to the invention is particularly suitable for the flexible design of water features, the corresponding connectors are produced inexpensively in large variance and in conjunction with the electrical distributor 12, 13 form an easily assembled and waterproof unit that is extremely less susceptible to interference.
