Die Aufgabe wird erfindungsgemäß gelöst mit einer Steckverbinderanordnung mit den Merkmalen des Anspruches 1.The object is achieved with a connector arrangement the features of claim 1.

Eine solche Ausgestaltung weist eine verhältnismäßig geringe Anzahl an Bauteilen auf und lässt sich dadurch einfach und kostengünstig montieren. Einen wesentlichen Beitrag hierzu leistet daneben die lösbare Befestigung des Steckerstifts an der Abdeckung, die zudem eine einer modernen Modulbauweise entsprechenden Vormontage ermöglicht.Such a configuration has a relatively small number of components and can be installed easily and inexpensively. An essential one The detachable attachment of the connector pin to the cover also contributes to this, which is also a pre-assembly corresponding to a modern modular design allows.

Der an der Abdeckung befestigte Steckerstift erfährt während des Kontaktierens einen sicheren Halt, da die auftretenden Belastungen von der Abdeckung aufgenommen werden. Zum anderen gestattet die Verbindung der elektrischen Leitung mit dem einen Ende des Steckerstifts einen gegen Lösen gesicherten, zum Beispiel durch Verlöten oder Crimpen gebildeten, und damit verlässlichen Anschluss des elektrischen Leiters, wohingegen das andere, den Kontaktbereich der Vorrichtung kontaktierende Ende des Steckerstifts der jeweiligen Ausgestaltung des Kontaktbereichs entsprechend ausgebildet sein kann, um variabel für unterschiedliche Konstruktionen Anwendung zu finden.The connector pin attached to the cover experiences one during contacting secure hold, since the occurring loads are absorbed by the cover become.

Durch die Aufnahme lässt sich auf einfache Weise eine unkompliziert und kostengünstig herzustellende Crimpverbindung vorsehen, um das Ende der elektrischen Leitung gegen Lösen gesichert an das eine Ende des Steckerstifts anzuschließen und damit eine zuverlässige Kontaktierung zu gewähren.It when the rear end of the connector pin in the insertion direction is particularly advantageous to form an electrically conductive crimp connection a receptacle for the Has line. The inclusion makes it easy to find an uncomplicated one and provide inexpensive crimp connection to the end the electrical line secured against loosening at one end of the connector pin connect and thus ensure reliable contacting.

Von Vorteil kann es ferner sein, wenn das in Einführrichtung vordere Ende des Steckerstifts mit wenigstens einer konzentrischen Ausnehmung zur Aufnahme einer im Wesentlichen ringförmigen Kontaktfeder versehen ist. Die Ausnehmungen stellen einen beständigen Sitz der Kontaktfeder sicher. Das Vorsehen der Kontaktfeder führt zu einer Entkoppelung der komplementären Ausgestaltung von Steckerstift und Kontaktbereich und trägt damit zu einer variablen Verwendung der Steckverbinderanordnung bei. So lässt sich die Steckverbinderanordnung beispielsweise durch den Austausch unterschiedlich großer Kontaktfedern für verschieden dimensionierte Kontaktbereiche verwenden. Ferner bietet die Kontaktfeder die Möglichkeit eines guten Toleranzausgleiches.It can also be advantageous if the front end of the plug pin in the direction of insertion with at least one concentric recess for receiving an im Essentially annular contact spring is provided. Make the recesses a permanent seat of the contact spring. The provision of the contact spring leads to a decoupling of the complementary design of the connector pin and Contact area and thus contributes to a variable use of the connector assembly at. For example, the connector arrangement can be Exchange of different sized contact springs for different sized Use contact areas.

In einer besonders nutzbringenden Weiterbildung der erfindungsgemäßen Steckverbinderanordnung weist die Abdeckung im Bereich der Öffnung einen im Wesentlichen rohrförmigen Durchgang auf, in dem der Steckerstift einrastbar ist. Durch die Anordnung des Steckerstifts in dem Durchgang lässt sich ein wirksamer Schutz des Steckerstifts gegen Umgebungseinflüsse erreichen. Darüber hinaus lässt sich auf diese Weise ein sicherer Halt des Steckerstifts in der Abdeckung gewährleisten.In a particularly useful development of the connector arrangement according to the invention the cover essentially has one in the region of the opening tubular passage in which the connector pin can be snapped into place. Through the Arrangement of the connector pin in the passage can be an effective protection of the Reach connector pin against environmental influences. In addition, this ensures a secure hold of the connector pin in the cover.

Besonders vorteilhaft kann die Mantelfläche des Durchgangs in zumindest einem Befestigungsabschnitt mit Schlitzen versehen sein. Dies bietet den Vorteil, dass sich der Durchgang im Bereich des Befestigungsabschnitts nachgiebig gestalten lässt, um auf überaus einfache Art und Weise den Steckerstift im Durchgang festzulegen.The lateral surface of the passage can be particularly advantageous in at least one Fastening section to be provided with slots. This offers the advantage that the passage in the area of the fastening section can be made flexible, to fix the connector pin in the passage in a very simple way.

Zweckmäßig kann es ferner sein, wenn der Durchgang nach oben und/oder nach unten aus der Ebene der Abdeckung herausragt. Damit lässt sich einerseits eine überwiegend flache und damit kompakte Gestaltung der Abdeckung und andererseits eine zum sicheren Halt des Steckerstifts erforderliche Länge des Durchgangs erreichen. So kann sich der Durchgang beispielsweise auf der der elektrischen Vorrichtung zugewandten Seite bis zum Kontaktbereich hin erstrecken oder auf der dem elektrischen Leiter zugewandten Seite ein Stück weit die Ader der elektrischen Leitung aufnehmen, um etwa eine Zugentlastung der Ader und/oder einen geforderten Kabelabgang zu gewähren.It can also be expedient if the passage is upwards and / or downwards protrudes below the level of the cover. On the one hand, this allows one predominantly flat and thus compact design of the cover and on the other hand a length of passage required to hold the connector pin securely to reach. For example, the passage can be on that of the electrical device side facing to the contact area or on the side facing the electrical conductor to a certain extent the core of the electrical line record about a strain relief of the wire and / or a required Grant cable outlet.

Eine überaus vorteilhafte Ausgestaltung ist ferner dann gegeben, wenn die Öffnung mit einer Dichtung abdichtbar ist, um eine wirkungsvoll vor Umgebungseinflüssen geschützte Kontaktierung und damit eine wartungsfreie Ausgestaltung zu erzielen. Je nach Art der Dichtung lassen sich auf diese Weise Dichtigkeiten der Klasse IP 65 oder höher ermöglichen.A very advantageous embodiment is also given when the opening can be sealed with a gasket in order to be effective against environmental influences to achieve protected contacting and thus a maintenance-free design. Depending on the type of seal, this allows seals of class IP 65 or higher enable.

In Weiterbildung der Steckverbinderanordnung wird darüber hinaus vorgeschlagen, die Abdeckung durch eine Schraubverbindung an dem Gehäuse zu befestigen, so dass eine automatische Montage problemlos möglich ist.In a further development of the connector arrangement, it is also proposed that to attach the cover to the housing by means of a screw connection, so that automatic assembly is possible without any problems.

Schließlich wird vorgeschlagen, die Abdeckung aus Kunststoff zu fertigen, um eine in wirtschaftlicher Hinsicht einfache und kostengünstige Fertigung sicherzustellen.Finally, it is proposed to manufacture the cover from plastic to a to ensure simple and inexpensive production in economic terms.

Die hinsichtlich ihrer Erstreckung ober- und unterhalb der Ebene der Abdeckung 30 unterschiedlich lang ausgebildeten und damit etwa zur Aufnahme von elektrischen Leitern unterschiedlicher Polarität dienenden Durchgänge 32 weisen in einem Befestigungsabschnitt auf der dem Motor 40 zugewandten Seite der Abdeckung 30 Schlitze 33 auf, die eine nachgiebige Gestaltung der Durchgänge 32 bewirken.The in terms of their extension above and below the level of the cover 30 trained for different lengths and thus for receiving electrical Passages 32 serving different polarities point in a fastening section on the side of the cover 30 facing the motor 40 Slits 33, which cause a flexible design of the passages 32.

Der Steckverbinder ist außerdem mit mehreren Steckerstiften 20 versehen, die durch die Öffnung 31 in das Innere der Durchgänge 32 der Abdeckung 30 einführbar sind und bei Erreichen einer Endstellung im Befestigungsabschnitt aufgrund dessen nachgiebiger Gestaltung verrastet werden.The connector is also provided with a plurality of connector pins 20 which insertable into the interior of the passages 32 of the cover 30 through the opening 31 are due to and when reaching an end position in the fastening section its resilient design can be locked.

Die Steckerstifte 20 sind an ihrem in Einführrichtung hinteren Ende jeweils mit einem abisolierten Abschnitt der Adern 11 elektrisch leitend verbunden. Hierfür weisen die Steckerstifte 20 jeweils eine Aufnahme 21 für die abisolierten Abschnitte der Adern 11 auf, wobei die Adern 11 durch Crimpen in der Aufnahme 21 befestigt werden. Die Crimpverbindung kann dabei in Anlehnung an DIN 46235 mit Preßwerkzeugen nach DIN 48083 erzeugt werden und gasdicht ausgebildet sein.The connector pins 20 are each with a at their rear end in the insertion direction stripped section of the wires 11 electrically connected. Show for this the connector pins 20 each have a receptacle 21 for the stripped sections of the Veins 11, the veins 11 being fastened in the receptacle 21 by crimping. The crimp connection can be based on DIN 46235 with pressing tools generated according to DIN 48083 and designed to be gastight.

Um einen Kabelabgang von 180 ° zu erreichen, erstreckt sich ein an den Steckerstift 20 sich unmittelbar anschießender, mit einem isolierenden Mantel versehener Abschnitt der Adern 11 ein Stück weit durch den auf der dem Motor 40 abgewandten Seite der Abdeckung 30 geradlinig hervorstehenden Teil der Durchgänge 32 hindurch. Je nach Anforderung können die Durchgänge 32 in diesem Teil auch gekrümmt ausgebildet sein, um andere Neigungen für den Kabelabgang zu bilden.To achieve a cable outlet of 180 °, extend to the connector pin 20 immediately following, provided with an insulating jacket Section of the wires 11 a little way through that on the side facing away from the motor 40 Side of the cover 30 straight part of the passages 32 therethrough. Depending on the requirements, the passages 32 can also be curved in this part be designed to form other inclinations for the cable outlet.

In dem vorgenannten Teil der Durchgänge 32 ist in einem topfartig erweiterten Bereich eine Dichtung 12 angeordnet, welche die Öffnung 31 abdichtet, um das Innere des Gehäuses 41 vor Umgebungseinflüssen zu schützen, und zugleich eine wirksame Zugentlastung der Leitung 10 bewirkt. Die im Querschnitt etwas ringförmige Dichtung 12 ist auf die Leitung 10 aufgeschoben.In the aforementioned part of the passages 32 is in a pot-like expanded area a seal 12 is arranged which seals the opening 31 to the inside to protect the housing 41 from environmental influences, and at the same time an effective one Strain relief of line 10 causes. The somewhat circular in cross section Seal 12 is pushed onto line 10.

Das der Aufnahme 21 gegenüberliegende, in Einführrichtung vordere Ende der Steckerstifte 20 ist mit zwei hintereinander angeordneten konzentrischen Ausnehmungen 22 versehen. Diese dienen zur Aufnahme von im wesentlichen ringförmigen Kontaktfedern 23. Mittels der Kontaktfedern 23 sind die Steckerstifte 20 in einem als Kontaktblock ausgebildeten Kontaktbereich 42 des Motors 40 eingeklemmt, wodurch sich eine zuverlässige elektrische Kontaktierung ergibt. Die Kontaktfedern 23 ermöglichen einen guten Ausgleich der Fertigungstoleranzen.The opposite end of the receptacle 21 in the direction of insertion of the connector pins 20 has two concentric recesses arranged one behind the other 22 provided. These are used to accommodate essentially annular Contact springs 23.

In der in den Figuren 1a, b dargestellten montierten Stellung hintergreift der Rastabsatz 24 den Raststeg 34, so dass beide Elemente zusammen eine mit bestimmten Kraftaufwand lösbare Rastverbindung bilden. Diese wird hergestellt, wenn der Steckerstift 20 vollständig in die Öffnung 31 und den Durchgang 32 eingeführt ist.The connector pin 20 has approximately in its front third and seen in the longitudinal direction approximately between the area of the recess 22 and the receptacle 12 annular, radially projecting locking paragraph 24. In appropriate training the cover 30 has a corresponding location on the passage 32 radially inwardly projecting, annular locking web 34. In the in the figures 1a, b shown mounted position engages behind the locking paragraph 24 Locking web 34, so that both elements together with a certain effort Form releasable locking connection. This is made when the connector pin 20 is complete is inserted into the opening 31 and the passage 32.

Der zuvor beschriebene Steckverbinder zeichnet sich durch eine überaus einfache und automatisierbare Montage aus. Die einzelnen Montageschritte lassen sich dabei wie folgt charakterisieren: Die Adern 11 der Leitung 10 auf die gewünschte Länge ablängen; die Adern 11 zur Bildung von Anschlußlitzen abisolieren und die Dichtungen 12 auf die Adern 11 aufschieben; die Crimpverbindung zwischen dem abisolierten Abschnitt der Adern 11 und dem einen Ende des Steckerstifts 20 herstellen; die Steckerstifte 20 in den Durchgängen 32 der Abdeckung 30 verrasten; den so vormontierten Steckverbinder auf das Gehäuse 41 des Motors 40 aufsetzen und mit den Schrauben 50 befestigen.The connector described above is characterized by an extremely simple and automated assembly. The individual assembly steps can be done characterize as follows: The wires 11 of the line 10 to the desired length Cut; strip the wires 11 to form connecting leads and the Slide seals 12 onto the wires 11; the crimp connection between the produce the stripped section of the wires 11 and one end of the connector pin 20; engage the connector pins 20 in the passages 32 of the cover 30; place the pre-assembled connector on the housing 41 of the motor 40 and fasten with the screws 50.

Darüber hinaus tragen die geringe Anzahl an Bauelementen und die Möglichkeit der Vormontage zu reduzierten Montagezeiten und einem insgesamt relativ geringen Fertigungsaufwand im Vergleich zu herkömmlichen Steckverbindern bei. Die durch die Dichtungen 12 für Dichtigkeiten der Klasse IP 65 und höher geeignete Ausgestaltung ermöglicht überdies eine wartungsfreie Kontaktierung. Nicht zuletzt wird mit dem auf diese Weise robusten und damit langlebigen Steckverbinder einer variablen Kontaktierung modifiziert ausgestalteter Klemmbereiche 42 des Motors 40 Rechnung getragen, indem die Kontaktfedern 23 den jeweiligen Anforderungen entsprechend austauschbar sind.In addition, the small number of components and the possibility of Pre-assembly at reduced assembly times and a relatively low overall Manufacturing effort compared to conventional connectors. By the seals 12 are suitable for seals of class IP 65 and higher also enables maintenance-free contacting. Last but not least, with the robust and thus durable connector of a variable Contacting modified clamping areas 42 of the motor 40 Taken into account by the contact springs 23 according to the respective requirements are interchangeable.
