Description

Die Erfindung betrifft einen Winkelsteckverbinder zum Anbau an ein Aggregatgehäuse, mit einem Steckergehäuse und einem dieses teilweise übergreifenden Gehäuseflansch, der drehsicher an dem Aggregatgehäuse befestigbar ist, wobei das Steckergehäuse drehbar an dem Gehäuseflansch befestigt und zur Festlegung der Abgangsrichtung gegenüber dem Gehäuseflansch mit Drehwiderstand verdrehbar ist.The invention relates to an angle connector for attachment to an aggregate housing, with a connector housing and a partially cross-housing flange which is fastened against rotation on the unit housing, wherein the connector housing rotatably mounted on the housing flange and for determining the outgoing direction relative to the housing flange with rotational resistance is rotatable.

Derartige Winkelsteckverbinder werden beispielsweise zum Anschluss von Motoren eingesetzt. Dabei sollen die Winkelsteckverbinder leicht montierbar und in ihrer Abgangsrichtung einstellbar sein, wobei eine einmal eingestellte Abgangsrichtung sich unter der Einwirkung von Vibrationen, wie sie bei angetriebenen maschinellen Einrichtungen meist unvermeidlich sind, nicht unbeabsichtigt und selbstständig verändern kann. Somit darf die Einstellung der Abgangsrichtung nicht ohne Einwirkung eines gewissen Drehmoments möglich sein, damit das Steckergehäuse, das die Abgangsrichtung des Winkelsteckverbinders bestimmt, nach dem Einstellen in seiner Lage gegenüber dem Gehäuseflansch verbleibt.Such angle connectors are used for example for connecting motors. The angular connectors should be easy to assemble and adjustable in their outgoing direction, with a set outgoing direction can not unintentionally and independently change under the action of vibrations, as they are usually unavoidable in powered machinery. Thus, the adjustment of the outgoing direction must not be possible without the action of a certain torque, so that the connector housing, which determines the outgoing direction of the angle connector, after adjustment remains in its position relative to the housing flange.

Aus der DE 298 13 455 U1 ist ein Winkelstecker gemäß dem Oberbegriff bekannt, bei dem eine Rasteinrichtung zur gegenseitigen Festlegung eines Steckergehäuses und eines Gehäuseflansches in einer auswählbaren Verdrehstellung vorgesehen sind. Die Rasteinrichtung ist im Bereich einer gegenseitigen Überdeckung des Steckergehäuses und des Gehäuseflansches angeordnet, wobei die Verastung dort durch mindestens zwei ebene, aneinander anliegende Flächen zwischen den zu verrastenden Teilen und der Rasteinrichtung derart erfolgt, dass einer Anzahl am Außenumfang des Gehäuseflansches starr angeordnete Flächen eine entsprechende Anzahl unter Federlast radial beweglicher Flächen am Innenumfang des Steckergehäuses zusammen wirken. Die gegen Federlast beweglichen Flächen werden von Blattfederabschnitten gebildet, die, als Einzelteile oder als Verbund ausgebildet, vom Steckergehäuse getragen werden.From the DE 298 13 455 U1 is an angle plug according to the preamble known, in which a locking device for mutual fixing of a plug housing and a housing flange are provided in a selectable rotational position. The latching device is arranged in the region of a mutual overlap of the plug housing and the housing flange, wherein the Verastung done there by at least two flat, abutting surfaces between the parts to be latched and the latching device such that a number on the outer circumference of the housing flange rigidly arranged surfaces a corresponding Number under spring load radially movable surfaces on the inner circumference of the plug housing cooperate. The movable against spring load surfaces are formed by leaf spring sections, which, formed as individual parts or as a composite, are supported by the connector housing.

Bei den Blattfederabschnitten des vorangehend beschriebenen Gebrauchsmusters handelt es sich um filigrane Teile, die aufwendig herstellbar und schwierig; handhabbar sind, was einerseits einen unverhältnismäßig hohen Herstellungsaufwand erfordert und andererseits einen nicht unbeträchtliche Erschwerung im Zusammenbau des Winkelsteckverbinders mit sich bringt.In the leaf spring portions of the utility model described above are filigree parts that are complicated to produce and difficult; are manageable, which on the one hand requires a disproportionately high production cost and on the other hand brings a not inconsiderable difficulty in the assembly of the angle connector with it.

Ausgenehd von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen in seiner Abgangsrichtung einstellbaren Winkelsteckverbinder vorzuschlagen, der mit einem geringst möglichen Aufwand herstellbar ist und der ohne zur Hilfenahme von Werkzeugen in nahezu jeder beliebigen Abgangsrichtung einstellbar und zugleich gegen ein unbeabsichtigtes Verstellen hinreichend gesichert ist.Ausgenehd of this prior art, the present invention seeks to propose an adjustable angle in its outgoing angle connector that can be produced with the least possible effort and without the aid of tools in almost any arbitrary outlet direction adjustable and at the same time adequately secured against unintentional adjustment is.

Ferner sei auf die EP 1 465 293 A2 verwiesen, die ebenfalls die Merkmale des Oberbegriffs von Anspruch 1 offenbart.Furthermore, be on the EP 1 465 293 A2 which also discloses the features of the preamble of claim 1.

Diese Aufgabe wird erfindungsgemäß durch einen Winkelsteckverbinder mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.This object is achieved by an angle connector with the features of claim 1. Further advantageous embodiments can be found in the dependent claims.

Bei dem erfindungsgemäßen Winkelsteckverbinder ist das Steckergehäuse über eine elastische Hülse, die in einer stirnseitigen ringförmigen Ausnehmung des Steckergehäuses oder des Gehäuseflansches drehbar aufgenommen ist und die an dem jeweils zugeordneten Gehäuseflansch bzw. Steckergehäuse drehfest angreift, drehbar an dem Gehäuseflansch befestigt ist. Dabei ist im Bereich des gegenseitigen Übergriffes von dem Steckergehäuse und dem Gehäuseflansch das Steckergehäuse und der Gehäuseflansch in axialer und radialer Richtung zumindest abschnittsweise formschlüssig und in Umfangsrichtung mittels der Hülse kraftschlüssig miteinander verbunden. Die Hülse weist insbesondere eine zylindrische, an den Durchmesser des Steckergehäuses und an die Länge des Gehäuseflansches angepasste Form auf und kann aus Stahl, Kunststoff oder anderen, für Federelemente geeigneten Materialien hergestellt sein.In the angle plug connector according to the invention, the plug housing via an elastic sleeve which is rotatably received in an end-side annular recess of the plug housing or the housing flange and rotatably engages the respectively associated housing flange or plug housing, is rotatably mounted on the housing flange. It is in the area of Mutual encroachment of the connector housing and the housing flange, the connector housing and the housing flange in the axial and radial directions at least partially positively and circumferentially connected by means of the sleeve frictionally with each other. The sleeve has, in particular, a cylindrical shape which is adapted to the diameter of the plug housing and to the length of the housing flange and can be made of steel, plastic or other materials suitable for spring elements.

Die zumindest Abschnittsweise axiale und radiale formschlüssige Verbindung des Steckergehäuses zu dem Gehäuseflansch entsteht durch das Ineinandergreifen der beiden Teile mit geringem axialen und oder radialen Spiel, wobei das Steckergehäuse in dem Gehäuseflansch drehbar festgelegt ist. In radialer Richtung sind Umfangsflächen des Gehäuseflansches und des Steckergehäuses in Anlage aneinander. Zur drehbaren Festlegung in axilaer Richtung sind an dem Steckergehäuse und dem Gehäuseflansch miteinander wirkende Sicherungsmitel vorgesehen, beispielsweise in Form eines radial ausladenden, einer Gegenfläche zugeordneten Kragens und/oder sich radial erstreckender, vorzugsweise federnd ausgebildeter Vorsprünge, die mit einer oder mehreren Nutausnehmungen im formschlüssigen Eingriff stehen. Somit kann sich das Steckergehäuse nicht ungewollt von dem Gehäuseflansch lösen.The at least sectionally axial and radial positive connection of the plug housing to the housing flange is formed by the engagement of the two parts with little axial and or radial play, wherein the plug housing is rotatably fixed in the housing flange. In the radial direction are peripheral surfaces of the housing flange and the plug housing in abutment against each other. For rotatable fixing in axilaer direction cooperating securing Mitel are provided on the plug housing and the housing flange, for example in the form of a radially extending, a counter surface associated collar and / or radially extending, preferably resiliently formed projections, with one or more Nutausnehmungen in positive engagement stand. Thus, the connector housing can not unintentionally come off the housing flange.

In Umfangsrichtung ist das Steckergehäuse über die elastische Hülse kraftschlüssig mit dem Gehäuseflansch verbunden. Die Hülse ist zwischen dem Steckergehäuse und dem Gehäuseflansch angeordnet und drehfest mit dem Gehäuseflansch oder dem Steckergehäuse im Eingriff. Sie wird von dem Steckergehäuse bzw. dem Gehäuseflansch, in dem sie drehbar in einer ringförmigen Ausnehmung aufgenommen ist, über einen Teil Ihrer Innen- und/oder Außenmantelfläche und/oder der zugeordneten Stirnfläche beaufschlagt und hemmt das Steckergehäuse beim Drehen des Steckergehäuses gegenüber dem Gehäuseflansch durch Reibung.In the circumferential direction, the connector housing via the elastic sleeve is positively connected to the housing flange. The sleeve is disposed between the connector housing and the housing flange and non-rotatably with the housing flange or the connector housing in engagement. It is acted upon by the plug housing or the housing flange, in which it is rotatably received in an annular recess, over part of its inner and / or outer lateral surface and / or the associated end face and inhibits the plug housing when rotating the plug housing relative to the housing flange Friction.

Die Hülse wird beim Einstellen der Abgangsrichtung des Winkelsteckverbinders in axialer und/oder radialer Richtung reversibel elastisch verformt. Durch die Form der stirnseitigen ringförmigen Ausnehmung des Steckergehäuses oder des Gehäuseflansches, in dem die elastische Hülse drehbar eingreift, kann der Drehwiderstand gleichmäßig über den gesamten Umfang des Gehäuseflansches oder bereichsweise eingestellt werden. Zudem kann der Drehwiderstand auch durch die Geometrie der Hülse und durch Auswahl geeigneter Materialien für die Hülse beeinflusst werden.The sleeve is reversibly elastically deformed in adjusting the outgoing direction of the angle plug connector in the axial and / or radial direction. By the form the end-side annular recess of the plug housing or the housing flange in which the elastic sleeve rotatably engages, the rotational resistance can be adjusted uniformly over the entire circumference of the housing flange or partially. In addition, the rotational resistance can also be influenced by the geometry of the sleeve and by selecting suitable materials for the sleeve.

Vorteilhafterweise liegt die elastische Hülse in der ringförmigen Ausnehmung, die als stirnseitige Ringnut oder als stirnseitige Ringstufe ausgebildet sein kann, radial wellenförmigen verformt und unter Vorspannung ein. Zur Vorspannung sind an der Ausnehmung an mindestens einer Umfangsfläche mehrere insbesondere in Umfangsrichtung zueinander versetzt angeordnete Nocken vorgesehen, die auf die Hülse verformend einwirken. Dabei wird die Anzahl der Wellen der Hülse von der Anzahl der Nocken der Umfangsfläche bestimmt. Abhängig von der Höhe der Nocken gegenüber der Umfangsfläche, dem Abstand der Nocken zueinander und deren Anordnung an einer oder zwei Umfangsflächen der ringförmigen Ausnehmung variiert der Drehwiderstand des Winkelsteckverbinders.Advantageously, the elastic sleeve is in the annular recess, which may be formed as an end-side annular groove or as an end-side ring stage, deformed radially undulating and under bias. For biasing a plurality of in particular circumferentially offset from each other arranged cams are provided on the recess on at least one circumferential surface, which act on the sleeve deforming. The number of waves of the sleeve is determined by the number of cams of the peripheral surface. Depending on the height of the cam relative to the peripheral surface, the distance between the cams to each other and their arrangement on one or two peripheral surfaces of the annular recess varies the rotational resistance of the angle connector.

Vorzugsweise ist die Hülse während der Drehbewegung des Steckergehäuses gegenüber dem Steckerflansch in radialer Richtung dynamisch elastisch verformbar. Dabei wird die elastische Hülse beim Drehen des Steckergehäuses des Winkelsteckverbinders entlang ihren Umfang, in Drehrichtung des Steckergehäuses sich bewegend, dynamisch in radialer Richtung verformt, wobei eine tangential zur Hülse wirkende Reibungskraft zu überwinden ist.Preferably, the sleeve is dynamically elastically deformable during the rotational movement of the plug housing relative to the plug flange in the radial direction. In this case, the elastic sleeve during rotation of the plug housing of the angle connector along its circumference, in the direction of rotation of the plug housing is moving, dynamically deformed in the radial direction, wherein a tangential force acting on the sleeve friction force is overcome.

In einer bevorzugten Ausführungsform der Erfindung ist die Hülse in dem Gehäuseflansch oder dem Steckergehäuse, an dem die Hülse drehfest angreift, mit radialem Spiel gelagert. Damit kann sich die Hülse über ihre gesamte Länge gleichmäßig verformen, wenn sie beim Drehen des Steckergehäuses gegenüber dem Gehäuseflansch abschnittsweise dynamisch radial ausgelenkt wird, so dass die Verformung problemlos wellenförmig entlang dem Umfang der Hülse fortschreiten kann..In a preferred embodiment of the invention, the sleeve is mounted in the housing flange or the connector housing, on which the sleeve engages against rotation, with radial play. Thus, the sleeve can deform evenly over its entire length, if it is radially deflected when rotating the connector housing relative to the housing flange sections radially, so that the deformation can easily progress undulating along the circumference of the sleeve.

In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Winkelsteckverbinders ist die Hülse aus einem Kunststoffmaterial hergestellt. Zur Herstellung können alle dem Fachmann bekannten Gieß- und Tiefziehverfahren Anwendung finden. Dies ermöglicht geringe Materialkosten und eine kostengünstige Herstellung für eine Serienfertigung.In an advantageous embodiment of the angle plug connector according to the invention, the sleeve is made of a plastic material. For the production, all casting and deep-drawing methods known to the person skilled in the art can be used. This allows low material costs and cost-effective production for mass production.

In einer Ausführungsform ist die Hülse beschichtet. Die Beschichtung dient insbesondere der Reibungsminimierung und kann mit allen zur Oberflächenbeschichtung geeigneten, industrieüblichen Verfahren aufgebracht werden.In one embodiment, the sleeve is coated. The coating serves in particular to minimize friction and can be applied with all industry-standard methods suitable for surface coating.
