Elektrische Winkelsteckverbinder der eingangs genannten Art sind aus dem Stand der Technik in vielfältigen Ausführungsformen bekannt. Beispielhaft wird auf die Druckschrift EP 3 089 284 A1 verwiesen. Electrical angle connectors of the type mentioned are known from the prior art in various embodiments. By way of example, reference is made to document EP 3 089 284 A1.
Die EP 3 089 284 A1 offenbart einen gattungsgemäßen Winkelstecker mit einem gewinkelten Steckergehäuse und mit einer Flanschhülse, die das Steckergehäuse im Bereich eines ersten Steckergehäuseabschnitts umfangsseitig umgibt, wobei die Flanschhülse mittels einer in Richtung einer Längsachse des ersten Stecker- gehäuseabschnitts wirkenden Axial-Haltevorrichtung an dem ersten Steckerge- häuseabschnitt befestigt ist, und wobei die Axial-Haltevorrichtung einen Radial- anschlag aufweist, der sich von einer Innenseite der Flanschhülse in Richtung einer Außenseite des ersten Steckergehäuseabschnitts erstreckt und eine Gegen- lagerung aufweist, welche mit dem ersten Steckergehäuseabschnitt zur Festlegung der axialen Position zueinander in Wirkverbindung steht. Dabei weist die Axial- Flaltevorrichtung ein Federelement auf, welches in einem Zwischenraum zwischen der Innenseite der Flanschhülse und einer Außenseite des ersten Stecker- gehäuseabschnitts angeordnet ist und eine axiale Federkraft erzeugt, wobei die Gegenlagerung einen Verrastring aufweist, der mit einer Rasteinrichtung in einer Rastnut in der Außenseite des ersten Steckergehäuseabschnitts verrastet ist. In dem Zwischenraum ist überdies ein Dichtring, vorzugsweise ein O-Ring ange- ordnet, der den Ringspalt zwischen der Innenseite der Flanschhülse und der Außenseite des ersten Steckergehäuseabschnitts abdichtet. Zudem weist die Flanschhülse an einem hinteren Ende des Winkelsteckers eine nach hinten offene Aufnahmenut für eine Dichtung auf, wobei die Aufnahmenut mit einem radial inneren Nutsteg begrenzt ist, der der axial fluchtend mit der den Zwischenraum begrenzenden Innenseite der Flanschhülse ausgebildet ist. EP 3 089 284 A1 discloses a generic angle plug with an angled plug housing and with a flange sleeve which peripherally surrounds the plug housing in the region of a first plug housing section, wherein the flange sleeve is secured to the housing by means of an axial holding device acting in the direction of a longitudinal axis of the first plug housing section first connector housing portion is fixed, and wherein the axial holding device has a radial stop which extends from an inner side of the flange sleeve in the direction of an outer side of the first connector housing portion and a counter-bearing, which with the first connector housing portion for fixing the axial position to each other in Active compound is. In this case, the axial-Flaltevorrichtung a spring element, which is arranged in a space between the inside of the flange sleeve and an outer side of the first plug housing portion and generates an axial spring force, wherein the abutment has a locking ring, which with a locking device in a locking groove in the outside of the first connector housing portion is locked. In addition, a sealing ring, preferably an O-ring, which seals the annular gap between the inside of the flange sleeve and the outside of the first connector housing section, is arranged in the interspace. In addition, the flange sleeve at a rear end of the angle plug on a rearwardly open receiving groove for a seal, wherein the receiving groove is bounded by a radially inner Nutsteg, which is formed axially aligned with the gap defining the inside of the flange sleeve.
Das Steckergehäuse und die Flanschhülse sind dabei üblicherweise aus Metall hergestellt. Der Winkelsteckverbinder wird beispielsweise als Anschlusssteck- verbinder für Elektromotoren verwendet und an das Motorgehäuse angeflanscht. Beim Verdrehen des gewinkelten Steckergehäuses beim Anbringen am dem Motorgehäuse oder durch Vibrationen beim Betrieb des Motors kann es zu metallischen Abrieb kommen, der unmittelbar in das Motorinnere gelangen und zu Betriebsstörungen des Motors bzw. führen bzw. Motorschäden verursachen kann. Dies wird dem vorstehend aufgeführten Stand der Technik als nachteilig angesehen. The plug housing and the flange sleeve are usually made of metal. The angle plug connector is used, for example, as a connection plug connector for electric motors and flanged onto the motor housing. When twisting the angled connector housing when mounted on the motor housing or vibrations during operation of the engine can cause metallic abrasion, which can get directly into the interior of the engine and cause malfunction of the engine or cause engine damage. This is considered disadvantageous to the prior art cited above.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Möglichkeit vorzuschlagen, mit der das Eindringen von metallischem Abrieb aus dem Über- lappungsbereich von Steckergehäuse und die Flanschhülse in das Motorinnere, d.h. das Aggregatgehäuse zu verhindern. Dabei soll die Lösung einfach, kostengünstig und verschleißfest sein. Based on this, the object of the invention is to propose a possibility with which the penetration of metallic abrasion from the overlap region of connector housing and the flange sleeve into the engine interior, ie to prevent the unit housing. The solution should be simple, inexpensive and resistant to wear.
Diese Aufgabe wird erfindungsgemäß durch elektrischen Winkelsteckverbinder mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Weitere vorteilhafte Ausführungsformen sind den rückbezogenen Ansprüchen zu entnehmen. This object is achieved by electrical angle connector with the features of the independent claim 1. Further advantageous embodiments can be found in the dependent claims.
Danach ist bei dem erfindungsgemäßen elektrischen Winkelsteckverbinder zum Anbau an ein Aggregatsgehäuse das ringförmige Dichtelement, das stirnseitig an dem Befestigungsflansch auf einer dem Aggregatsgehäuse zugeordneten Anlageseite angebracht ist, als Formdichtung aus mindestens einem elastischen Material hergestellt und weist einen Axialpressabschnitt und einen Radialpress- abschnitt auf, wobei der Axialpressabschnitt eine Abdichtung zwischen dem Befestigungsflansch und dem Aggregatgehäuse und der Radialpressabschnitt eine Abdichtung zwischen dem Befestigungsflansch und dem endseitigen Schenkelabschnitt des Verbindungsschenkels bewirkt, wenn der Winkelsteck- verbinder über den Flanschsockel mit dem Aggregatgehäuse verbunden, beispielsweise verschraubt ist. Der Radialpressabschnitt liegt einer sich axial erstreckeckenden Mittelachse des Verbindungsschenkels und des Flanschsockels näher als der Axialpressabschnitt und schließt vorzugsweise direkt an diesen an. Der Axialpressabschnitt und der Radialpressabschnitt werden jeweils von einem ringförmigen Teilbereich der Formdichtung gebildet. Diese beiden Teilbereiche können aus einem elastisch verformbaren Material oder aus unterschiedlichen derartigen Materialien bestehen. Thereafter, in the electrical angle plug connector according to the invention for attachment to an aggregate housing, the annular sealing element, which is attached to the end face on the mounting flange on an aggregate housing associated plant side, made as a molded gasket of at least one elastic material and has an Axialpressabschnitt and a Radialpress- section on the Axialpressabschnitt causes a seal between the mounting flange and the unit housing and the Radialpressabschnitt a seal between the mounting flange and the end leg portion of the connecting leg when the angle plug connector is connected via the flange base with the unit housing, for example screwed. The radial pressing section is closer to an axially extending center axis of the connecting leg and the flange base than the axial pressing section and preferably directly adjoins it. The Axialpressabschnitt and the Radialpressabschnitt are each formed by an annular portion of the molded seal. These two sections may consist of an elastically deformable material or of different such materials.
Dabei weist der Winkelsteckverbinder ein gewinkeltes Steckergehäuse und einen Flanschsockel auf, wobei das Steckergehäuse einen Anschlussschenkel für einen elektrischen Steckverbinder sowie einen Verbindungsschenkel für den Flansch- sockel und der Flanschsockel einen Befestigungsflansch für das Aggregats- gehäuse sowie eine Aufnahmehülse für den Verbindungsschenkel auf. In dem Anschlussschenkel ist ein isolierender Kontaktträger mit elektrischen Steck- kontakten angeordnet, die als Steckstifte oder Steckbuchsen ausgebildet sein können. Der Verbindungsschenkel des Steckergehäuses durchsetzt zumindest die Aufnahmehülse des Flanschsockels, steht vorzugsweise mit einem freien endseitigen Schenkelabschnitt über den Befestigungsflansch vor und ist in Um- fangsrichtung drehbar an dem Flanschsockel festgelegt, wobei mindestens eine ringförmige Dichtung zwischen der Aufnahmehülse und dem Verbindungsschenkel angeordnet sind. In this case, the angle plug connector has an angled plug housing and a flange base, wherein the plug housing has a connection leg for an electrical plug connector and a connection leg for the flange socket and the flange socket has a mounting flange for the unit housing and a receiving sleeve for the connection leg. In the connection leg, an insulating contact carrier with electrical plug contacts is arranged, which are designed as plug pins or sockets can. The connecting leg of the plug housing passes through at least the receiving sleeve of the Flanschsockels, preferably projects with a free end leg portion on the mounting flange and is rotatably fixed in the circumferential direction on the Flanschsockel, wherein at least one annular seal between the receiving sleeve and the connecting leg are arranged.
Vorzugsweise ist der Axialpressabschnitt des von der Formdichtung gebildeten ringförmigen Dichtelements in axialer Richtung der Formdichtung höher ausgebildet als der Radialpressabschnitt und damit weniger nachgiebig als der Radialpressabschnitt. Bevorzugt ist der Radialpressabschnitt lamellenförmig ausgebildet und weist eine sich radial nach innen von dem Axialpressabschnitt weg erstreckende umlaufende Dichtlippe auf. Der Radialpressabschnitt ist in radialer Richtung der Formdichtung ähnlich formstabil wie der Axialpressabschnitt in axialer Richtung der Formdichtung. Die Dichtlippe ist an einem Innenrand der Radial- pressabschnittes angeordnet und erstreckt sich in Umfangsrichtung entlang dem Radialpressabschnitt. Preferably, the Axialpressabschnitt of the annular sealing element formed by the molded seal in the axial direction of the molded seal is formed higher than the Radialpressabschnitt and thus less compliant than the Radialpressabschnitt. Preferably, the radial press section is lamellar and has a radially inwardly away from the Axialpressabschnitt circumferential sealing lip. The radial compression section is similar dimensionally stable in the radial direction of the molded seal as the Axialpressabschnitt in the axial direction of the molded seal. The sealing lip is arranged on an inner edge of the radial press section and extends in the circumferential direction along the radial press section.
In einer Ausführungsform weist dass der Befestigungsflansch auf der Anlageseite eine umlaufende Ringnut zur Aufnahme der Formdichtung auf. In einer bevorzugten Ausführungsform der Erfindung weist der Axialpressabschnitt der Formdichtung mindestens zwei radial nach außen abstehende Halteflügel auf und die Ringnut vorzugsweise seitliche radial verlaufende Fortsätze zur Aufnahme der Halteflügel der Formdichtung auf. In one embodiment, the attachment flange has a circumferential annular groove on the abutment side for receiving the molded seal. In a preferred embodiment of the invention, the Axialpressabschnitt the molded seal at least two radially outwardly projecting retaining wings and the annular groove preferably on the side radially extending projections for receiving the retaining wings of the molded seal.
Bei einer vorteilhaften Variante des erfindungsgemäßen Winkelsteckverbinders weist der endseitige Schenkelabschnitt des Verbindungsschenkels des Stecker- gehäuses eine umlaufende Ringausnehmung auf, wobei vorzugsweise zumindest die Dichtlippe des Radialpressabschnittes der Formdichtung in die Ringaus- nehmung des Verbindungsschenkels eingreift und idealerweise am Grund der Ringausnehmung in Anlage ist. Damit dichten der lamellenförmig ausgeführte Radialpressabschnitt und/oder die Dichtlippe des Radialpressabschnitt einen zylinderförmigen Spalt zwischen einer Innenseite der Aufnahmehülse und einer Außenseite des Verbindungsschenkels des Steckergehäuses sowohl radial wie auch axial ab, sodass kein unerwünschter Abrieb mehr in das Aggregatgehäuse geraten kann. In an advantageous variant of the angle plug connector according to the invention, the end leg section of the connecting leg of the plug housing has a circumferential annular recess, wherein preferably at least the sealing lip of the radial pressing section of the molded seal engages in the ring recess of the connecting leg and ideally abuts the bottom of the annular recess. Thus, the lamellar radial section and / or the sealing lip of the radial press section seal one cylindrical gap between an inner side of the receiving sleeve and an outer side of the connecting leg of the plug housing both radially and axially, so that no unwanted abrasion can get into the unit housing.
Die Formdichtung, die stirnseitig an dem Befestigungsflansch auf der dem Aggregatsgehäuse zugeordneten Anlageseite angebracht ist, ist dort vorzugsweise unverlierbar angeordnet. Dazu ist zum einen die auf der Anlageseite vorgesehene umlaufende Ringnut zur Aufnahme der Formdichtung an die Geometrie und die Maße der Formdichtung derart angepasst, dass eine leichte Presspassung vorliegt. Zum anderen greift der ringförmige Radialpressabschnitt der Formdichtung, insbesondere dessen Dichtlippe in die Ringausnehmung des Verbindungs- schenkels ein und verhindert ein ungewolltes Lösen der Formdichtung von dem Befestigungsflansch bis zu der Montage des Winkelsteckverbinder an einem Aggregatsgehäuse. Zusätzlich können die optional vorgesehenen Halteflügel der Formdichtung, die an dem Axialpressabschnitt angeordnet sind, in Verbindung mit den seitlichen Fortsätzen der Ringnut, in dem die Formdichtung einliegt, zu- sätzlichen Halt für die Formdichtung geben. Durch all diese Maßnahmen wird die Formdichtung vor dem Lösen von der Anlageseite des Befestigungsflansches gesichert. The molded seal, which is mounted on the front side of the mounting flange on the plant housing associated plant side, there is preferably arranged captive. For this purpose, on the one hand, provided on the plant side circumferential annular groove for receiving the molded seal to the geometry and the dimensions of the molded seal adapted so that a slight interference fit is present. On the other hand, the annular radial press section of the molded seal, in particular its sealing lip, engages in the annular recess of the connecting leg and prevents unintentional release of the molded seal from the fastening flange until assembly of the angular connector on an aggregate housing. In addition, the optionally provided retaining vanes of the molded gasket, which are arranged on the axial compression section, can give additional hold for the molded gasket in conjunction with the lateral extensions of the annular groove in which the molded gasket rests. Through all these measures, the molded seal is secured against loosening of the plant side of the mounting flange.
