Description

Die Erfindung geht aus von einem elektrischen Installationsbausatz nach der Gattung des unabhängigen Patentanspruchs. Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Installationsbausatz dieser Gattung so auszubilden, daß eine möglichst schnelle, übersichtliche und fehlerfreie elektrische Installation von Maschinen und Anlagen möglich ist, und zwar nach Wahl direkt am Schaltschrank oder am Aufstellungsort. Dabei soll der Installationsbausatz eine Montage und auch eine Wartung ermöglichen, die kein besonders geschultes Fachpersonal erfordert.The invention is based on an electrical installation kit according to the type of the independent claim. The invention has for its object to design an electrical installation kit of this type so that the quickest possible, clear and error-free electrical installation of machines and systems is possible, directly at the control cabinet or at the installation site. The installation kit should enable assembly and maintenance that does not require specially trained specialist personnel.

Aus der US-A 4 179 179 ist ein mehrpoliger elektrischer Steckverbinder bekannt, der zur Durchführung eines Kabelbaumes durch die Trennwand zwischen Motor- und Fahrgastraum eines Fahrzeugs dient. Der bekannte Steckverbinder hat als Grundelement ein in die Durchführungsöffnung der Trennwand einsetzbares und diese dicht verschließendes mehrpoliges Steckeraufnahmeteil, das fest mit dem einen Strang des Kabelbaums verbunden und derart mit Kontaktbuchsen und Kontaktstiften bestückt ist, daß je nach Fahrzeugtyp bedarfsweise ein oder mehrere, mit dem oder mit weiterführenden Abschnitten des Kabelbaums verbundene Steckerteile in der richtigen Lage einsteckbar sind. Diese Ausführung bietet nur eine beschränkte Anzahl von Steckplätzen, die wegen der unterschiedlichen Ausbildung der Kontaktelemente offenbar auch nicht beliebig vergrößtert werden kann, ohne daß die Übersichtlichkeit verloren geht. Außerdem könnte ein aus den gezeigten Steckverbindungselementen zusammengestellter Installationsbausatz die bei Maschinen und Anlagen erforderte Vielfältigkeit bezüglich der Installationsaufgaben offenbar nicht bieten.From US-A 4 179 179 a multi-pole electrical connector is known, which is used to lead a wiring harness through the partition between the engine and passenger compartments of a vehicle. The known connector has as a basic element an insertable into the through opening of the partition and this tightly closing multi-pin connector receptacle, which is firmly connected to one strand of the wiring harness and is equipped with contact sockets and contact pins such that, depending on the vehicle type, one or more, with or plug parts connected to further sections of the wiring harness can be inserted in the correct position. This version offers only a limited number of slots, which obviously cannot be enlarged arbitrarily because of the different design of the contact elements, without the clarity being lost. In addition, an installation kit composed of the plug-in connection elements shown could obviously not offer the variety of installation tasks required for machines and systems.

Eine ähnliche Ausführung zeigt und beschreibt die GB-A 13 93 059, bei welcher mehrere leistenförmige Steckmodule mit jeweils in Reihe angeordneten Steckeraufnahmen nebeneinander auf einem flachen Träger befestigbar sind und gemeinsam ein Raster von Kontaktbuchsen mit in beiden Koordinatenrichtungen des Rasters gleichen Teilungsabständen bilden. Einzelne Kontaktelemente sind entsprechend einer bestimmten Kontaktierungsaufgabe mit einem oder mehreren anderen Kontaktelementen verbunden, wobei jedoch offenbar keine Maßnahmen zum Sicherstellen der richtigen Zuordnung von Steckerteilen und Steckeraufnahme getroffen sind. Auch dieser Ausführung würde es bei einer größeren Anzahl von Steckplätzen an der für die elektrische Installation von Maschinen und Anlagen im erhöhten Maß geforderten Übersichtlichkeit fehlen.A similar embodiment shows and describes GB-A 13 93 059, in which a plurality of strip-shaped plug-in modules, each with a row of connector receptacles, can be fastened next to one another on a flat support and together form a grid of contact sockets with the same spacing in both coordinate directions of the grid. Individual contact elements are connected to one or more other contact elements in accordance with a specific contacting task, but apparently no measures have been taken to ensure the correct assignment of plug parts and plug receptacles. This version would also lack the clarity required for the electrical installation of machines and systems with a greater number of slots.

Aus der DE-A 21 32 123 ist eine elektrische Steckverbindungsvorrichtung mit mehreren, vielpoligen Steckeraufnahmen bekannt, bei welcher die innere Verdrahtung zwischen den Steckeraufnahmen leicht geändert werden kann. Diese Vorrichtung hat ein behälterartiges Gehäuse, an dessen Seitenwänden die Steckeraufnahmen sitzen, deren einzelne Kontakte über auf gebogenen Trägerplättchen aufgebrachte gedruckte Schaltungen mit am Gehäuseboden befestigten Steckkontakten verbunden sind. Diese sind gruppenweise zu Steckermodulen zusammengefaßt und werden über Einzeldrähte, deren Enden mit Kontaktstiften versehen sind, je nach Vorschrift des Anwendungsfalles miteinander verbunden. Diese Ausführung benötigt spezialisierte Fachkräfte für die Einzelverdrahtung und ist offensichtlich für Installationen, über die auch höhere elektrische Leistungen übertragen werden sollen, nicht geeignet.From DE-A 21 32 123 an electrical connector device with several, multi-pole connector receptacles is known, in which the internal wiring between the connector receptacles can be easily changed. This device has a container-like housing, on the side walls of which the plug receptacles are seated, the individual contacts of which are connected to plug contacts fastened to the housing base via printed circuits mounted on curved carrier plates. These are grouped together into plug modules and are connected to each other via individual wires, the ends of which are provided with contact pins, depending on the specification of the application. This version requires specialized specialists for individual wiring and is obviously not suitable for installations via which higher electrical power is also to be transmitted.

Vorteile der ErfindungAdvantages of the invention

Darin ist ein mit entsprechenden Buchsen versehener, bekannter Stecker einsteckbar, der über Kabel mit einem nicht gezeigten Schaltschrank elektrisch verbunden ist. Fig. 1 zeigt, daß alternativ zum Anschlußstecker 22 auch ein Kabel 23 direkt in den Steckverteiler 20 führen kann. Die Anschlüsse sowohl des Anschlußsteckers 22 als auch aller acht Steckeraufnahmen 21 sind auf einer gemeinsamen Leiterplatte 24 zusammengefaßt. Das insbesondere aus Kunststoff bestehende, zweiteilige Gehäuse 25 des Steckverteilers 20 trägt auf seiner Oberseite 26 für jeweils vier Steckeraufnahmen 21 eine durchlaufende Dichtung 27, die aufgeklebt ist. Die Dichtung 27 ist für den Durchlaß jedes Steckerteiles zum Inneren jeder Steckeraufnahme 21 im wesentlichen rechteckig bei 28 ausgespart. Jeder einzelnen Steckeraufnahmen 21 des Steckverteilers 20 ist eine etwa viereckige Schutzkappe 29 zugeordnet, die bei Nichtgebrauch der einzelnen Steckeraufnahme 21 auf diese aufgesetzt wird und diese unter Zusammenpressung der Dichtung 27, der jeweiligen geforderten Schutzart entsprechend, feuchtigkeitsdicht abdeckt. Zwei angeformte, z. B. diametral angeordnete, Zentrierstifte 19 greifen dabei formschlüssig in zwei zugeordnete Kontaktbuchsen 30 ein und sorgen für einwandfreien Sitz.The central element of the kit 10 is a plug distributor 20, which carries a total of eight 7-pin plug receptacles 21 as well as a 40-pin connector 22 common to all plug receptacles 21 or a corresponding socket, which is centered between two parallel rows with four plug receptacles 21 each is arranged. The connector plug 22 is of a conventional type. A known plug, which is provided with corresponding sockets, can be inserted therein and is electrically connected to a switch cabinet, not shown, via cables. Fig. 1 shows that, as an alternative to the connector 22, a cable 23 can lead directly into the plug distributor 20. The connections of both the connector 22 and all eight connector receptacles 21 are combined on a common circuit board 24. The two-part housing 25 of the plug distributor 20, which is made of plastic in particular, has a continuous seal 27 on its upper side 26 for four plug receptacles 21, which is glued on. The seal 27 is recessed substantially at 28 for the passage of each connector part to the interior of each connector receptacle 21. Each individual plug receptacle 21 of the plug distributor 20 is assigned an approximately square protective cap 29, which is placed on the individual plug receptacle 21 when it is not in use and covers it with compression of the seal 27, in accordance with the respective required degree of protection, in a moisture-proof manner. Two molded, z. B. diametrically arranged, centering pins 19 engage positively in two associated contact sockets 30 and ensure a perfect fit.

Die einzelnen Kontaktbuchsen 30 jeder einzelnen Steckeraufnahme 21 befinden sich im Gehäuse 25 und enden kurz vor dessen Oberseite 26. Die jeweils sieben Kontaktbuchsen 30 jeder einzelnen Steckeraufnahme 21 des Steckverteilers 20 sind entlang einer Rechtecklinie gruppiert. Im Zentrum der Steckeraufnahme befindet sich eine fest eingebrachte Gewindebuchse 31. Sind die Steckeraufnahmen 21 mittels Schutzkappen 29 verschlossen, so greift in jede Gewindebuchse 31 eine an der Schutzkappe 29 gehaltene Gewindeschraube 32 mit ihrem Gewindeabsatz ein. Bei angezogener Gewindeschraube 32 ist die Dichtung 27 zusammengepreßt und die Schutzkappe 29 unter dichtem Abschluß der Steckeraufnahme 21 gehalten. Die Gewindeschraube 32 ist mittels eines Sprengringes 33 axial verschiebesicher und zugleich unverlierbar an der Schutzkappe 29 gehalten.The individual contact sockets 30 of each individual plug receptacle 21 are located in the housing 25 and end shortly before the upper side 26 thereof. The seven contact sockets 30 of each individual plug receptacle 21 of the plug distributor 20 are grouped along a rectangular line. In the center of the plug receptacle there is a firmly inserted threaded bushing 31. If the plug receptacles 21 are closed by protective caps 29, a threaded screw 32 held on the protective cap 29 engages with its threaded shoulder in each threaded bushing 31. When the threaded screw 32 is tightened, the seal 27 is pressed together and the protective cap 29 is held tightly against the plug receptacle 21. The threaded screw 32 is axially secured against displacement and at the same time captive on the protective cap 29 by means of a snap ring 33.

Vom grundsätzlichen Aufbau her ähnlich gestaltet ist als weiterer, zum Bausatz 10 gehörender Steckmodul eine Kupplung 12 (Fig. 16-18), die mit einer elektrischen Zuleitung 13 (Fig. 1) versehen ist. In Fig. 16-18 fehlt die Zuleitung noch. Sie ist dort durch einen Gehäusedurchbruch 14 in das Innere des Gehäuses 15 zu führen und elektrisch anzuschließen. Die Kupplung 12 ist mit lediglich einer 7-poligen Steckeraufnahme 21 versehen, die genauso gestaltet ist, wie jede Steckeraufnahme 21 des Steckverteilers 20. Auf der Oberseite verläuft rings um die Steckeraufnahme 21 eine Dichtung 27 mit rechteckförmiger Aussparung. Im Zentrum der Steckeraufnahme befindet sich in gleicher Weise eine fest eingesetzte Gewindebuchse 31. Man kann die Steckeraufnahme 21 der Kupplung 12, wenn nötig, mittels der Schutzkappe 29 bei Nichtgebrauch verschließen. Alternativ dazu wird in die Steckeraufnahme 21 ein Stecker eingesteckt, dessen Steckposition dann zusätzlich noch durch Einschrauben emer Gewindeschraube in die Gewindebuchse 31 gesichert wird. Für die Steckeraufnahme 21 der Kupplung 12 sowie deren Einzelteile sind deshalb die gleichen Bezugszeichen wie für die Steckeraufnahme 21 des Steckverteilers 20 verwendet, um dadurch besonders deutlich zu machen, daß jede Steckeraufnahme 21 des Steckverteilers 20 hinsichtlich der Ausbildung und Anordnung der Kontaktbuchsen 30 der Steckeraufnahme 21 der Kupplung 12 völlig entsprechend ausgebildet ist.The basic structure is similarly designed as a further plug-in module belonging to the kit 10, a coupling 12 (Fig. 16-18), which is provided with an electrical supply line 13 (Fig. 1). In Fig. 16-18 the feed line is still missing. It is to be led through a housing opening 14 into the interior of the housing 15 and to be electrically connected. The coupling 12 is provided with only a 7-pin plug receptacle 21, which is designed in exactly the same way as each plug receptacle 21 of the plug distributor 20. A seal 27 with a rectangular recess extends around the plug receptacle 21 on the upper side. In the same way, a fixed threaded bushing 31 is located in the center of the plug receptacle. If necessary, the plug receptacle 21 of the coupling 12 can be closed by means of the protective cap 29 when not in use. Alternatively, a plug is inserted into the plug receptacle 21, the plug position of which is then additionally secured by screwing the threaded screw into the threaded bushing 31. For the plug receptacle 21 of the coupling 12 and its individual parts, the same reference numerals are therefore used as for the plug receptacle 21 of the plug distributor 20, in order to make it particularly clear that each plug receptacle 21 of the plug distributor 20 with regard to the design and arrangement of the contact sockets 30 of the plug receptacle 21 the clutch 12 is designed entirely accordingly.

Zum Bausatz 10 gehören außerdem Adapter 34 (Fig. 1) und 35 (Fig. 12-15). Der Adapter 34 weist einen gehäusefesten 7-poligen Steckerteil mit aus dem Adaptergehäuse vorstehenden Kontaktstiften auf. Der Adapter 34 ist mit einer elektrischen Zuleitung versehen, die beim Beispiel in Fig. 1 aus der zur Kupplung 12 führenden Zuleitung 13 im einen Fall bzw. aus der Zuleitung 36 besteht, die zu einem nur schematisch angedeuteten Motor 37 führt. Der Adapter 34 mit 7-poligem Steckerteil ist beim Beispiel gemäß Fig. 1 in eine zugeordnete 7-polige Steckeraufnahme 21 des Steckverteilers 20 eingesteckt.The kit 10 also includes adapters 34 (Fig. 1) and 35 (Fig. 12-15). The adapter 34 has a 7-pin connector part fixed to the housing with contact pins protruding from the adapter housing. The adapter 34 is provided with an electrical supply line, which in the example in FIG. 1 consists of the supply line 13 leading to the coupling 12 in one case or of the supply line 36 which leads to a motor 37, which is only indicated schematically. In the example according to FIG. 1, the adapter 34 with a 7-pin plug part is inserted into an assigned 7-pin plug receptacle 21 of the plug distributor 20.

Beim Ausführungsbeispiel nach Fig. 12-15 weist der Adapter 35 zwei oder auch vier gleichartig ausgebildete Steckerteile 38 auf, die jeweils sieben aus dem Adaptergehäuse 39 vorstehende Kontaktstifte 40 aufweisen. Die Kontaktstifte 40 jedes Steckerteils 38 sind ebenfalls entlang einer Rechtecklinie gruppiert (Fig. 13), so daß die Kontaktstifte 40 eines Steckerteils 38 beim Anbringen eines Adapters 34 oder 35 am Steckverteiler 20 paßgenau in eine Steckeraufnahme 21 oder zwei nebeneinander befindliche Steckeraufnahmen eingreifen, wobei der Adapter 35 dann parallel zur Reihe mit vier Steckeraufnahmen 21 des Steckverteilers 20 ausgerichtet ist. Im Zentrum des Steckerteils 38 trägt der Adapter 35 eine zumindest endseitig mit Gewinde versehene Schraube 41, die beim Einstecken des Adapters 35 in eine Gewindebuchse 31 der Steckeraufnahme 21 einschraubbar ist. Durch Festziehen der Gewindeschraube 41 wird der eingesteckte Adapter 35 in der Steckstellung gesichert. Die Gewindeschraube 41 ist mittels eines Sprengringes 42 axial verschiebesicher und unverlierbar gehalten. Beim Ablösen des Adapters 35 vom Steckverteiler 20 hilft die Schraube 41 in der Weise, daß beim Lösen der Schraube 41 der Adapter 35 mit seinen Kontaktstiften 40 aus den Kontaktbuchsen 30 einer Steckeraufnahme 21 des Steckverteilers 20 herausgedrückt wird, bis der Gewindeeingriff der Schraube 41 aufhört. Dies erleichert das Herausziehen und verhindert Verkanten und Verbiegen oder Abbrechen der Kontaktstifte 40. Der Adapter 34 (Fig. 1) hat nur ein Steckerteil 38 mit sieben Kontaktstiften 40. Der Adapter 35 gemäß Fig. 12-15 hat in einem Gehäuse 39 zwei derartige Steckerteile 38 vereinigt. Die elektrische Zuleitung kann wählbar an zwei verschiedenen Stellen des Gehäuses 39 in dieses eingeführt werden. Hierzu sind nach Wahl die kreisförmig markierten Gehäuseteile 43 oder 44 herauszubrechen.In the exemplary embodiment according to FIGS. 12-15, the adapter 35 has two or even four plug parts 38 of identical design, each of which has seven contact pins 40 protruding from the adapter housing 39. The contact pins 40 of each connector part 38 are also grouped along a rectangular line (FIG. 13), so that the contact pins 40 of a connector part 38 when attached gene of an adapter 34 or 35 on the plug distributor 20 engage in a precise fit in a plug receptacle 21 or two plug receptacles located next to one another, the adapter 35 then being aligned parallel to the row with four plug receptacles 21 of the plug distributor 20. In the center of the plug part 38, the adapter 35 carries a screw 41, which is threaded at least at the end and which can be screwed into a threaded socket 31 of the plug receptacle 21 when the adapter 35 is inserted. By tightening the threaded screw 41, the inserted adapter 35 is secured in the plugged position. The threaded screw 41 is held axially securely and captively by means of a snap ring 42. When detaching the adapter 35 from the plug distributor 20, the screw 41 helps in such a way that when the screw 41 is loosened, the adapter 35 with its contact pins 40 is pressed out of the contact sockets 30 of a plug receptacle 21 of the plug distributor 20 until the threaded engagement of the screw 41 stops. This facilitates pulling out and prevents the contact pins 40 from tilting and bending or breaking off. The adapter 34 (FIG. 1) has only one plug part 38 with seven contact pins 40. The adapter 35 according to FIGS. 12-15 has two such plug parts in a housing 39 38 united. The electrical feed line can be inserted into the housing 39 at two different locations. For this purpose, the circularly marked housing parts 43 or 44 are to be broken out.

Ein weiteres wesentliches Element des Bausatzes 10 ist eine Steckleiste 50, die zum einen einen 7-poligen Steckerteil 51 völlig gleicher Art wie der Steckerteil 38 des Adapters 35 sowie vier 4-polige, als Steckdosen ausgebildete Steckeraufnahmen 52 aufweist. Die 4-poligen Steckeraufnahmen 52 sind zum Einstecken besonders angepaßter Einzelstecker 80 (Fig. 19-22) ausgebildet. Der Steckerteil 51 ist hinsichtlich der Ausbildung und Anordnung seiner Kontaktstifte 53 genauso aufgebaut, wie jeder Steckerteil 38 des Adapters 35. Im Zentrum der Rechtecklinie, auf der die Kontaktstifte 53 liegen, ist eine Schraube 54 angeordnet, die zumindest endseitig mit einem Gewindeabsatz versehen ist und die mittels eines Sprengringes 55 axial verschiebesicher und unverlierbar gehalten ist. Die Steckleiste 50 ist mit ihrem Steckerteil 51 in eine der Steckeraufnahmen 21 des Steckverteilers 20 einsteckbar, wobei dann die Steckleiste 50 etwa rechtwinklig zur Reihe mit vier Steckeraufnahmen 21 verläuft, also in Fig. 1 nach links oder nach rechts hin etwa rechtwinklig absteht, wie rechts angedeutet ist.Another essential element of the kit 10 is a connector strip 50, which has a 7-pin connector part 51 of the same type as the connector part 38 of the adapter 35 and four 4-pin connector receptacles 52 designed as sockets. The 4-pin connector receptacles 52 are designed to insert specially adapted individual connectors 80 (FIGS. 19-22). The connector part 51 is constructed in terms of the design and arrangement of its contact pins 53 in exactly the same way as each connector part 38 of the adapter 35. In the center of the rectangular line on which the contact pins 53 lie, a screw 54 is arranged, which is provided at least at the end with a threaded shoulder and which is held axially displaceably and captively by means of a snap ring 55. The plug-in strip 50 can be inserted with its plug part 51 into one of the plug receptacles 21 of the plug distributor 20, in which case the plug-in strip 50 extends approximately at right angles to the row with four plug receptacles 21, that is to say it projects approximately at right angles in FIG. 1, as on the right is indicated.

Der Steckerteil 51 sowie die vier Steckeraufnahmen 52 der Steckleiste 50 sind entlang einer Reihe und hintereinander folgend angeordnet. Alle Anschlüsse der Steckeraufnahmen 52 sowie des Steckerteils 51 sind auf einer gemeinsamen Leiterplatte 56 zusammengefaßt, die ein flexibles Leiterelement 57 aufweist, das eine stufige Anordnung überbrückt. Die Kontaktstifte 53 des Steckerteils 51 ragen aus dem Gehäuse 58 heraus und stehen zu einer Seite hin vor. Die vier Steckeraufnahmen 52 befinden sich auf der gegenüberliegenden Seite des Gehäuses 58 und sind dort vertieft angeordnet. Dabei ist jeder Steckeraufnahme 52 eine Aufnahmeöffnung 59 vorgelagert, in die ein Einzelstecker 80 hineinpaßt. Die vier Kontaktbuchsen 60 jeder Steckeraufnahme 52 sind längs einer Vierecklinie, z. B. einer Rechtecklinie, symmetrisch gruppiert. Im Zentrum der Steckeraufnahme 52 ist im Gehäuse 58 eine Gewindebuchse 61 fest angeordnet.The connector part 51 and the four connector receptacles 52 of the connector strip 50 are arranged along a row and in succession. All connections of the connector receptacles 52 and of the connector part 51 are combined on a common printed circuit board 56 which has a flexible conductor element 57 which bridges a step arrangement. The contact pins 53 of the plug part 51 protrude from the housing 58 and protrude to one side. The four connector receptacles 52 are located on the opposite side of the housing 58 and are arranged there in a recessed manner. Each connector receptacle 52 is preceded by a receiving opening 59 into which a single connector 80 fits. The four contact sockets 60 of each connector receptacle 52 are along a square line, e.g. B. a rectangular line, grouped symmetrically. A threaded bushing 61 is fixedly arranged in the housing 58 in the center of the plug receptacle 52.

Die nicht benötigten Steckeraufnahmen 52 der Steckleiste 50 lassen sich mittels Abdeckkappen 62 feuchtigkeitsdicht verschließen. Jede Abdeckkappe 62 weist einen der Kontur der Aufnahmeöffnung 59 entsprechenden, in diese hinein etwas vorstehenden Abschnitt 63 auf. Dort, wo die Aufnahmeöffnung 59 in die Oberseite des Gehäuses 56 übergeht, ist eine ringsum laufende Vertiefung 64 vorgesehen. Die Abdeckkappe 62 trägt einen Dichtungsring 65, der hier als 0-Ring ausgebildet ist. Der Dichtungsring 65 sitzt im Kehlbereich der Abdeckkappe dort, wo der in die Aufnahmeöffnung 59 formgenau hineinpassende Abschnitt 63 in einen größeren Flanschbereich 66 übergeht. Der dortige Kehlbereich verläuft bogenförmig und ist an die Kontur des Dichtungsringes 65 gut angepaßt. Im Zentrum enthält die Abdeckkappe 62 eine Gewindeschraube 67, die in schon erläuterter Weise mittels eines Sprengringes 68 axial gesichert und unverlierbar gehalten ist. Die Gewindeschraube 67 greift dabei in die Gewindebuchse 61 ein, wobei beim Anziehen der Gewindeschraube 67 der Dichtungsring 65 unter dichtender Pressung zwischen dem Flanschbereich 66 und der Vertiefung 64 und der Oberseite des Gehäuses 58 verformt wird. Jede Abdeckkappe 62 trägt zwei damit einstückige, z. B. diametral angeordnete, Zentrierstifte 73, die in zwei zugeordnete Kontaktbuchsen 60 eingreifen. Die Zentrierstifte 73 geben ebenfalls die richtige Stellung für die Abdeckkappe 62 vor und erleichtern deren richtiges Aufsetzen.The connector receptacles 52 of the connector strip 50 that are not required can be closed moisture-tight by means of cover caps 62. Each cover cap 62 has a section 63 corresponding to the contour of the receiving opening 59 and projecting into it. Where the receiving opening 59 merges into the top of the housing 56, an all-round recess 64 is provided. The cover cap 62 carries a sealing ring 65, which is designed here as an 0-ring. The sealing ring 65 is seated in the throat area of the cover cap where the section 63 that fits into the receiving opening 59 merges into a larger flange area 66. The throat area there is arched and is well adapted to the contour of the sealing ring 65. In the center, the cover cap 62 contains a threaded screw 67 which, in the manner already explained, is axially secured by means of a snap ring 68 and held captive. The threaded screw 67 engages in the threaded bushing 61, the sealing ring 65 being deformed when the threaded screw 67 is tightened under sealing pressure between the flange region 66 and the depression 64 and the upper side of the housing 58. Each cap 62 carries two integral, z. B. diametrically arranged, centering pins 73 which engage in two associated contact sockets 60. The centering pins 73 also provide the correct position for the cover cap 62 and facilitate its correct placement.

Die Aufnahmeöffnungen 59 einerseits und die in diese hineinpassenden Abschnitte 63 der Abdeckkappen 62 andererseits sind jeweils im Querschnitt unsymmetrisch, z. B. unrund oder unsymmetrisch oval ausgebildet. Letzteres ist beim gezeigten Ausführungsbeispiel der Fall. Das Oval hat zwei zueinander etwa parallele Längsseiten, die auf der einen Hälfte über eine andere Bogenlinie verbunden sind als auf der gegenüberliegenden Seite. Durch diese Formgebung ist nur eine einzige Einsteckposition vorgegeben. Zur Erleichterung der Orientierung bei anzubringender Abdeckkappe 62 ist außerdem das Gehäuse 58 und in zugeordneter Weise die Abdeckkappe 62 noch mit einer Kerbe 69 bzw. 70 versehen. Jeder Steckeraufnahme 52 der Steckleiste 50 sind zwei zu einem Bauteil 71 vereinigte Leuchtdioden zugeordnet, die im Gehäuse 58 enthalten sind.The receiving openings 59 on the one hand and the sections 63 of the cover caps 62 fitting into them on the other hand are each asymmetrical in cross section, for. B. out of round or asymmetrical oval. The latter is the case in the embodiment shown. The oval has two long sides that are roughly parallel to each other and that are connected on one half by a different arc line than on the opposite side. This shape means that only a single insertion position is specified. To facilitate orientation when the cover cap 62 is to be attached, the housing 58 and, in an associated manner, the cover cap 62 are also provided with a notch 69 and 70, respectively. Each connector receptacle 52 of the connector strip 50 is assigned two light-emitting diodes which are combined to form a component 71 and which are contained in the housing 58.

Einzelheiten des in eine Steckeraufnahme 52 passenden Einzelsteckers 80 zeigen Fig. 19-22. Der Einzelstecker 80 stellt z. B. ein einstückiges, vergossenes Bauteil mit eingegossener Zuleitung 82 dar. Der Einzelstecker 80 trägt am Ende vier vorstehende Kontaktstifte 82, die in ihrer Ausbildung und Anordnung den Kontaktbuchsen 60 einer Steckeraufnahme 52 der Steckleiste 50 entsprechen. Die Kontaktstifte 82 sitzen in einem Formabschnitt 83, der in die Aufnahmeöffnung 59 hineinpaßt und hinsichtlich seines Querschnittes demjenigen der Aufnahmeöffnung 59 entspricht. Der Formabschnitt 83 hat also die gleiche Form wie z. B. der Abschnitt 63 der Abdeckkappe 62. Er trägt einen Dichtungsring 84 in Gestalt eines 0-Ringes. Der Dichtungsring 84 ist dabei in gleicher Weise wie der Dichtungsring 65 der Abdeckkappe 62 in einem Kehlbereich aufgenommen, wobei dort auch eine zusätzliche Rille vorgesehen sein kann, in der der Dichtungsring 84 lagert. Der Einzelstecker 80 enthält im Zentrum der Kontaktstifte 82 eine Gewindeschraube 85, die zumindest auf dem aus dem Formabschnitt 83 vorstehenden Ende ein Gewinde trägt. Die Gewindeschraube 85 ist axial verschiebesicher und unverlierbar gehalten. Beim Einstecken eines Einzelsteckers 80 in eine zugeordnete Steckeraufnahme 52 der Steckleiste 50 wird die Steckverbindung durch Einschrauben der Gewindeschraube 85 in die zentrale Gewindebuchse 61 zusätzlich gesichert. Ist die Gewindeschraube 85, wie zuvor erläutert, z. B. mittels eines Sprengringes axial gesichert, so führt ein Herausdrehen der Gewindeschraube 85 zum Herausdrücken der Kontaktstifte 82 aus den Kontaktbuchsen 60. Das Herausziehen wird dadurch erleichert.Details of the individual plug 80 which fits into a plug receptacle 52 are shown in FIGS. 19-22. The single plug 80 provides z. B. is a one-piece, molded component with molded lead 82. The single connector 80 carries four at the end protruding contact pins 82, which correspond in their design and arrangement to the contact sockets 60 of a plug receptacle 52 of the connector strip 50. The contact pins 82 are seated in a shaped section 83 which fits into the receiving opening 59 and corresponds in cross section to that of the receiving opening 59. The mold section 83 thus has the same shape as z. B. the section 63 of the cap 62. It carries a sealing ring 84 in the form of an 0-ring. The sealing ring 84 is accommodated in the same way as the sealing ring 65 of the cover cap 62 in a throat area, an additional groove in which the sealing ring 84 is supported can also be provided there. The single plug 80 contains in the center of the contact pins 82 a threaded screw 85 which carries a thread at least on the end protruding from the molded section 83. The threaded screw 85 is axially displaceable and captive. When a single plug 80 is inserted into an associated plug receptacle 52 of the plug connector 50, the plug connection is additionally secured by screwing the threaded screw 85 into the central threaded bushing 61. Is the threaded screw 85, as previously explained, for. B. axially secured by means of a snap ring, unscrewing the threaded screw 85 leads to pushing the contact pins 82 out of the contact sockets 60. The removal is thereby facilitated.

Beim Steckerteil 51 der Steckleiste 50, bei jedem Steckerteil 38 des Adapters 34 oder 35 sowie beim Einzelstecker 80 ist jeweils ein Kontaktstift länger als die übrigen Kontaktstifte 53 bzw. 40 bzw. 82. Er steht über die übrigen vor. An diesen längeren Kontaktstift ist das Erdungskabel angeschlossen. Diese Ausbildung führt dazu, daß beim Einstecken zuerst die Erdung erfolgt und daß diese beim Herausziehen bis zuletzt und dann noch erhalten bleibt, wenn die demgegenüber kürzeren Kontaktstifte schon aus den Kontaktbuchsen entfernt sind.In the case of the plug part 51 of the plug connector 50, each plug part 38 of the adapter 34 or 35 and the single plug 80, one contact pin is longer than the other contact pins 53 or 40 or 82. It projects above the others. The earth cable is connected to this longer contact pin. This training leads to the fact that the earthing takes place first when plugging in and that it is retained until the end when it is pulled out and then when the contact pins, which are shorter in comparison, have already been removed from the contact sockets.

Alle beschriebenen Steckmodule tragen Bezeichnungsschilder. Beim Ausführungsbeispiel ist derartiges lediglich für den Steckverteiler 20 nicht dargestellt.All plug-in modules described have labels. In the exemplary embodiment, such is only shown for the plug distributor 20.

Die Steckleiste 50 (Fig. 6-8) weist im Gehäuse 58 dort, wo der Steckerteil 51 und ferner auch die vier Steckeraufnahmen 52 sitzen, eine im Querschnitt etwa T-förmige Halterungsnut 72 auf, in die ein entsprechend geformtes Bezeichnungsschild vom offenen Ende her einschiebbar ist. Entsprechende Halterungsnuten 72 weist auch das Gehäuse 39 des Adapters 35 (Fig. 14) auf, und zwar je Steckerteil 38 eine Halterungsnut 72. Auch die Kupplung 12 (Fig. 17) sowie der Einzelstecker 80 (Fig. 20) sind mit einer derartigen Halterungsnut 72 versehen.The connector strip 50 (Fig. 6-8) has in the housing 58 where the connector part 51 and also the four connector receptacles 52 are located, a cross-sectionally approximately T-shaped mounting groove 72, into which a correspondingly shaped label from the open end can be inserted. Corresponding mounting grooves 72 also have the housing 39 of the adapter 35 (FIG. 14), namely a mounting groove 72 for each plug part 38. The coupling 12 (FIG. 17) and the individual plug 80 (FIG. 20) are also provided with such a mounting groove 72 provided.

Beim Beispiel in Fig. 1 ist beim Steckverteiler 20 die in Fig. 1 rechte, obere Steckeraufnahme 21 dadurch belegt, daß in diese eine Steckleiste 50 mit ihrem Steckerteil 51 eingesteckt ist. Darunterfolgend sind gestrichelt zwei weitere, eingesteckte Steckleisten 50 angedeutet. Die beiden äußeren Steckeraufnahmen 52 der Steckleiste 50 sind mittels aufgesetzter und festgeschraubter Abdeckkappen 62 feuchtigkeitsdicht verschlossen. Bei einer Steckeraufnahme 52 ist die Abdeckkappe 62 abgenommen und von der Innenseite zu sehen. In die beiden offenen Steckeraufnahmen 52 können also jeweils Einzelstecker 80 eingesteckt werden. Fig. 1 zeigt ferner eine Steckleiste 50, die fernab vom Steckverteiler 20 an diesen angeschlossen ist. Hierzu ist z. B. in eine Steckeraufnahme 21 der in Fig. 1 linken Reihe des Steckverteilers 20 ein Adapter 34 eingesteckt, an den über die Zuleitung 13 die Kupplung 12 angeschlossen ist. In die 7-polige Steckeraufnahme 21 (Fig. 16-18) der Kupplung 12 ist eine Steckleiste 50 mit ihrem Steckerteil 51 eingesteckt. In die einzelnen Steckeraufnahmen der Steckleiste 50 sind jeweils Einzelstecker 80 (Fig. 19-22) eingesteckt, die über Kabel z. B. zu schematisch angedeuteten Motoren führen.In the example in FIG. 1, the upper connector receptacle 21 on the right in FIG. 1 is occupied in that a connector strip 50 with its connector part 51 is inserted into it. Below this, two further inserted plug-in strips 50 are indicated by dashed lines. The two outer connector receptacles 52 of the connector strip 50 are closed moisture-tight by means of attached and screwed-on cover caps 62. In the case of a plug receptacle 52, the cover cap 62 is removed and can be seen from the inside. Individual plugs 80 can thus be inserted into the two open plug receptacles 52. Fig. 1 also shows a header 50, which is connected far from the plug distributor 20 to this. For this purpose, e.g. B. inserted into a plug receptacle 21 of the left row of the plug distributor 20 in FIG. 1, an adapter 34 to which the coupling 12 is connected via the feed line 13. In the 7-pin connector receptacle 21 (Fig. 16-18) of the coupling 12, a connector strip 50 is inserted with its connector part 51. In the individual plug receptacles of the connector strip 50, individual plugs 80 (FIGS. 19-22) are inserted, which are connected via cables, for. B. lead to schematically indicated engines.

Der 40-polige Anschlußstecker 22 am Steckverteiler 20 hat als 41. Pol die Erde, die an den metallischen Rahmen des Anschlußsteckers 22 angeschlossen ist. Von diesen insgesamt 41 Polen dienen 8 x 4 = 32 Pole als Ein- und Ausgänge zur Steuerung. 4 x 2 = 8 Pole dienen der Stromversorgung, mit Wechselstrom oder mit Gleichstrom.The 40-pin connector 22 on the plug distributor 20 has the 41st pole as the earth, which is connected to the metallic frame of the connector 22. Of these 41 poles in total, 8 x 4 = 32 poles serve as inputs and outputs for control. 4 x 2 = 8 poles are used for power supply, with alternating current or with direct current.

Zu jeder Steckeraufnahme 52 gehört eine schaltungstechnisch damit verbundene Kontrollanzeige in Form des beschriebenen Bauteils 71, wonach dieses Bauteil eine rote Leuchtdiode und eine grüne Leuchtdiode hat, die zu einer Baueinheit zusammengefaßt sind. Die elektrische Verbindung des Bauteils 71 mit der zugehörigen Steckeraufnahme 52 ist so getroffen, daß das Bauteil 71 dann aufleuchtet, wenn in die Steckeraufnahme 52 ein Stecker 80 eingesteckt ist und in diesem Zweig ein Strom fließt. Bei Wechselstrom leuchten die grüne und die rote Leuchtdiode des Bauteils 71 auf. Bei Gleichstrom, und zwar plusschaltend, leuchtet die rote LED auf. Bei Gleichstrom, minusschaltend, leuchtet statt dessen die grüne LED auf. Sind die Phasen vertauscht, erkennt man dies an unterschiedlichem Aufleuchten der LED. Das Bauteil 71 dient also als Kontrollanzeige bei richtiger Polung und Stromfluß. Es erleichtert die richtige Polung beim Anschluß. Auch später noch zeigt das Bauteil 71 an, ob der jeweils angeschlossene Pfad stromlos ist oder unter Spannung steht.Each plug receptacle 52 has a control display connected to it in terms of circuitry in the form of the described component 71, according to which this component has a red light-emitting diode and a green light-emitting diode, which are combined to form a structural unit. The electrical connection of the component 71 with the associated connector receptacle 52 is made such that the component 71 lights up when a connector 80 is inserted into the connector receptacle 52 and a current flows in this branch. With alternating current, the green and red LEDs of component 71 light up. In the case of direct current, namely positive switching, the red LED lights up. With direct current, minus switching, the green LED lights up instead. If the phases are reversed, you can see this by the different lighting of the LED. The component 71 thus serves as a control display with correct polarity and current flow. It facilitates the correct polarity when connecting. Even later, component 71 indicates whether the path connected in each case is de-energized or under voltage.
