Description
Die vorliegende Erfindung betrifft ein Dichtelement für eine elektrische Leitung gemäß den Merkmalen von Anspruch 1.The present invention relates to a sealing element for an electric line according to the features of
Die vorliegende Erfindung betrifft daher insbesondere ein Dichtelement zur Abdichtung eines Litzenleiterbündels für einen Steckverbinder umfassend einen im Wesentlichen zylinderförmigen Dichtkörper mit wenigstens zwei Litzenleiterkanälen, vorzugsweise mehreren unterschiedlichen Litzenleiterkanälen mit unterschiedlichem Querschnitt, wobei die jeweiligen Litzenleiterkanäle an wenigstens einem Innenabschnitt sich verjüngen bzw. sich in den Litzenleiterkanal hinein erstrecken und dadurch eine den Querschnitt A reduzierende bzw. verjüngende Auswölbungen aufweisen.The present invention therefore relates in particular to a sealing element for sealing a stranded conductor bundle for a connector comprising a substantially cylindrical sealing body with at least two stranded conductor channels, preferably a plurality of different stranded conductor channels with different cross sections, the respective stranded conductor channels tapering at least one inner section or into the stranded conductor channel extend and thereby have a cross-section A reducing or tapering bulges.

Es ist bekannt, elektrische Leitungen zur Übertragung elektrischer Signale in Steckverbinder zu verwenden. Beispielsweise können Elektromotoren oder andere Applikationen durch elektrische Leitung mit Energie versorgt werden.It is known to use electrical lines for transmitting electrical signals in connectors. For example, electric motors or other applications can be powered by electrical power.
Es ist ferner bekannt, dass bei durch einen Mantel nach außen elektrisch isolierten Leitungen, insbesondere bei Litzenleitern ein Flüssigkeitstransport in Längsrichtung entlang der Leitung unerwünscht erfolgen kann.It is also known that in the case of lines which are electrically insulated by a jacket to the outside, in particular in stranded conductors, liquid transport in the longitudinal direction along the line can take place undesirably.
Wird ein Ende einer solchen Leitung mit Wasser beaufschlagt, so kann das Wasser entlang der Litzenleiter zum anderen Ende der Leitung transportiert werden somit auch ggf. in den Steckverbinder hinein. Dies kann beispielsweise durch ein an einem Ende der Leitung am Eingang des Steckverbinders abdichtendes Element verhindert werden, welches den Flüssigkeitseintritt verhindert. Wasser kann darüber hinaus durch Kapillarwirkung entlang der Leitung in den Innenraum des Steckverbinders fließen, was ebenfalls unerwünscht ist. Dieses Problem tritt insbesondere bei Litzenleitern auf, die einen Wassertransport sowohl zwischen den Einzeldrähten der Litzen als auch zwischen dem Litzenleiter und dem umgebenden Mantel ermöglichen können.If water is applied to one end of such a line, the water can be transported along the stranded conductor to the other end of the line, thus possibly also into the connector. This can be prevented for example by a sealing element at one end of the line at the input of the connector, which prevents the liquid from entering. Water can also flow by capillary action along the line into the interior of the connector, which is also undesirable. This problem occurs in particular in stranded conductors, which can enable water transport both between the individual wires of the strands and between the stranded conductor and the surrounding jacket.
in vielen technischen Anwendungen ist ein solcher Flüssigkeitstransport nicht nur unerwünscht, sondern führt zu Schäden oder Ausfall der Applikation.In many technical applications such liquid transport is not only undesirable, but leads to damage or failure of the application.
Mit einer elektrischen Leitung verbundene Steckverbinder und/oder Applikationen müssen vor einem Flüssigkeitseintrag ausreichend geschützt werden.Connectors and / or applications connected to an electrical line must be adequately protected against liquid entry.
Aus der
Weiter ist im Stand der Technik bekannt, bei einem innenleiter, der aus einer einzelnen Litze besteht, eine Flüssigkeitseintrag innerhalb der Litze dadurch zu verhindern, dass ein zusätzliches Dichtmittel in die Litze eingesaugt und ausgehärtet wird.Further, it is known in the art to prevent liquid entry within the strand in an inner conductor consisting of a single strand by sucking and curing additional sealant into the strand.
In nachteiliger Weise ist dazu ein zusätzlicher kostenintensiver Prozess erforderlich.Disadvantageously, this requires an additional costly process.
Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, vorbesagte Nachteile zu überwinden und insbesondere ein Dichtelement geeignet auszubilden, um auch bei einem Litzenleiterbündel die einzelnen Litzenleiter zuverlässig vor Flüssigkeitseintritt oder Flüssigkeitsaustritt in oder aus dem Steckverbinder zu schützen.Against this background, it is an object of the present invention to overcome the aforementioned disadvantages and, in particular, to design a sealing element in order to reliably protect the individual stranded conductors against liquid ingress or liquid leakage into or out of the connector even in the case of a stranded conductor bundle.
Ferner ist es Aufgabe der vorliegenden Erfindung einen Steckverbinder mit einem solchen Dichtelement bereitzustellen.It is another object of the present invention to provide a connector with such a sealing element.
Die zuvor genannte Aufgabe wird gelöst durch ein Dichtelement mit den Merkmalen von Patentanspruch 1 sowie einem Steckverbinder mit den Merkmalen von Patentanspruch 6. Grundgedanke der vorliegenden Erfindung ist es, zunächst ein Dichtelement derart auszugestalten, dass die gewünschten Presskräfte an geeigneten Passagen der Litzenleiterkanäle auf die Litzenleiter wirken und ferner weiterhin Presskräfte auftreten, sobald das erfindungsgemäße Dichtelement in einen bestimmungsgemäßen Steckverbinder bzw. einen Aufnahmeraum eines Steckverbindergehäuses eingesetzt werden.The above object is achieved by a sealing element having the features of
Hierzu werden die Litzenleiterkanäle entsprechend so ausgebildet, dass an wenigstens einem Innenabschnitt eine sich in den Litzenleiterkanal hinein erstreckende Auswölbung vorgesehen ist. Auf diese Weise können die Litzen des Litzenleiterbündels z. B. am Ende eines Steckverbindergehäuses durch das besagte Dichtelement hindurchgeführt werden. Die Litzenleiterkanäle erzeugen an den besagten Stellen der Auswölbungen eine erhöhte Pressung auf die Litzenisolation, was eine besonders wirkungsvolle Dichtung mit sich bringt und insbesondere bestehende Toleranzen bei der Fertigung von Litzenleitern abfängt.For this purpose, the stranded conductor channels are correspondingly formed so that at at least one inner portion, a bulge extending into the strand conductor channel is provided. In this way, the strands of Litzenleiterbündels z. B. at the end of a connector housing are passed through said sealing element. The stranded conductor channels produce an increased pressure on the strand insulation at the said points of the bulges, which entails a particularly effective seal and, in particular, intercepts existing tolerances in the production of stranded conductors.
Erfindungsgemäß wird daher ein Dichtelement zur Abdichtung eines Litzenleiterbündels für einen Steckverbinder vorgeschlagen umfassend einen im Wesentlichen zylinderförmigen Dichtkörper mit wenigstens zwei Litzenleiterkanälen mit einem Querschnitt A, wobei die jeweiligen Litzenteiterkanäle an wenigstens einem Innenabschnitt eines sich in den Litzenleiterkanal hineinerstreckende und dadurch den Querschnitt A verjüngende bzw. reduzierende Auswölbung aufweist. Es ist vorteilhaft weiter vorgesehen, dass die Litzenleiterkanäle eine im Wesentlichen zylinderförmige Form mit einem runden Querschnitt aufweisen.According to the invention, therefore, a sealing element is proposed for sealing a stranded conductor bundle for a connector comprising a substantially cylindrical sealing body with at least two stranded conductor channels with a cross section A, wherein the respective strandedient channels at least an inner portion of a hineinerstreckende in the strand conductor channel and thereby the cross section A tapered or having reducing bulge. It is advantageously further provided that the stranded conductor channels have a substantially cylindrical shape with a round cross section.
In einer besonders vorteilhaften Ausführungsform der Erfindung weist der Dichtkörper an seinem Außenumfang eine umlaufende Nut auf. Die Nut ist in vorteilhafter Weise zwischen zwei umlaufenden Ringsegmentabschnitten in etwa mittig am Dichtelement angeordnet.In a particularly advantageous embodiment of the invention, the sealing body on its outer circumference on a circumferential groove. The groove is arranged in an advantageous manner between two circumferential ring segment sections approximately centrally on the sealing element.
Auf diese Weise kann eine vereinfachte Montage des Dichtelementes in einen Aufnahmeraum mit etwa gleichem Innendurchmesser erfolgen.In this way, a simplified assembly of the sealing element can be carried out in a receiving space with approximately the same inner diameter.
Es ist weiter mit Vorteil vorgesehen, dass die Litzenleiterkanäle im Wesentlichen entlang oder parallel zu einer gedachten Zylinderachse durch den zylinderförmigen Dichtkörper verlaufen. In einer weiter vorteilhaften Ausführungsform der Erfindung ist der Durchmesser der Litzenleiterkanäle bestimmungsgemäß unterschiedlich ausgebildet zum Durchführen unterschiedlicher Litzenleiter eines Litzenleiterbündels.It is further provided with advantage that the stranded conductor channels extend substantially along or parallel to an imaginary cylinder axis through the cylindrical sealing body. In a further advantageous embodiment of the invention, the diameter of the stranded conductor channels is intended differently designed for performing different stranded conductors of a stranded conductor bundle.
Auf diese Weise besteht die Möglichkeit, unterschiedliche Konfigurationen von Litzenleiterbündeln durch entsprechende Ausbildung geeigneter Öffnungsdurchmesser durch ein einziges Dichtelement hindurchzuführen. Erfindungsgemäß weist der Dichtkörper an seinem Außenumfang wenigstens eine umlaufende Auswölbung auf, die über die Hüllfläche der Zylinderform des Dichtelementes hinausragt. Unter "Hinausragen über die Hüllfläche der Zylinderform" ist zu verstehen, dass ein im Wesentlicher umlaufender Abschnitt des Dichtelementes weiter nach außen über eine Hüllkurve hinausragt, die als gedachte Hüllkurve vom eigentlichen Außenumfang des die Zylinderform definierendem Körper gebildet wird. Erfindungsgemäß weist der Dichtkörper an seinem Außenumfang auch eine oder mehrere punktuelle Auswölbungen auf. Erfindungsgemäß sind die Auswölbungen in ihrer Form als Noppen ausgebildet sind und ragen über bzw. aus der Hüllfläche der Zylinderform hinaus. Erfindungsgemäß sind die Noppen als Auswölbungen auf der zuvor genannten umlaufenden Auswölbung ausgebildet und stehen demnach noch weiter als die umlaufende Auswölbung gegenüber der Hüllfläche der Zylinderform nach außen hervor. Diese Noppen können insbesondere als Lagepositionierung des Dichtelementes in einem Steckverbindergehäuse bestimmt sein, so dass diese in korrespondierende Ausnehmungen der Löcher im Steckverbindergehäuse eingreifen können.In this way it is possible to pass different configurations of stranded conductor bundles by appropriate design of suitable opening diameter through a single sealing element. According to the invention, the sealing body has on its outer circumference at least one peripheral bulge, which projects beyond the envelope surface of the cylindrical shape of the sealing element. By "protrude beyond the envelope surface of the cylindrical shape" is to be understood that a substantially circumferential portion of the sealing element protrudes further outward over an envelope, which is formed as an imaginary envelope of the actual outer circumference of the cylinder shape defining body. According to the invention, the sealing body also has one or more punctiform bulges on its outer circumference. According to the invention, the bulges are formed in their shape as knobs and protrude beyond or out of the envelope surface of the cylindrical shape. According to the invention, the nubs are formed as bulges on the aforementioned circumferential bulge and are therefore even further than the circumferential bulge relative to the envelope surface of the cylindrical shape outward. These nubs can be determined in particular as a positional positioning of the sealing element in a connector housing, so that they can engage in corresponding recesses of the holes in the connector housing.
Ein weiterer Aspekt der vorliegenden Erfindung betrifft einen Steckverbinder mit einem erfindungsgemäßen Dichtelement. Es wird daher in einer vorteilhaften Ausbildung der Erfindung ein Steckverbinder mit einem Dichtelement bereitgestellt, wobei der Steckverbinder das Dichtelement in einem zylinderförmigen Aufnahmeraum seines Steckverbindergehäuses aufnimmt und wobei dessen Innendurchmesser kleiner ist als der Außendurchmesser des Dichtelementes, vorzugsweise kleiner als der Außendurchmesser des Dichtelementes im Bereich seiner außen umlaufenden Auswölbung.Another aspect of the present invention relates to a connector with a sealing element according to the invention. It is therefore provided in an advantageous embodiment of the invention, a connector with a sealing element, wherein the connector receives the sealing element in a cylindrical receiving space of its connector housing and wherein the inner diameter is smaller than the outer diameter of the sealing element, preferably smaller than the outer diameter of the sealing element in the region outside circumferential bulge.
Auf diese Weise wird eine Pressung gegen die Innenfläche des Gehäuses im Aufnahmeraum erzeugt und kann ein Festsitz der Dichtung gewährleistet werden. Damit die Dichtung nicht unbeabsichtigt aus dem Gehäuse herausrutschen kann, ragen die Noppen in entsprechende korrespondierende Löcher im Steckverbindergehäuse.In this way, a pressure is generated against the inner surface of the housing in the receiving space and a tight fit of the seal can be ensured. So that the seal can not accidentally slip out of the housing, the knobs protrude into corresponding holes in the connector housing.
Erfindungsgemäß ist der Steckverbinder daher mit Vorteil so ausgebildet, dass im Bereich des Aufnahmeraumes des Steckverbindergehäuses in dessen zylinderförmigen Wand korrespondierende Öffnungen oder Löcher zum Eingriff der noppenartigen Auswölbungen des Dichtelementes ausgebildet sind.According to the connector is therefore advantageously designed so that in the receiving space of the connector housing in the cylindrical wall corresponding openings or holes for engagement of the knob-like bulges of the sealing element are formed.
