Description

Die Erfindung betrifft einen elektrischen Steckverbinder, mit einem Steckerteil und einem mit dem Steckerteil zusammensteckbaren Gegensteckerteil sowie mit einer vom Steckerteil getragenen Überwurfmutter zum Verschrauben des Steckerteils mit einer Gewindehülse des Gegensteckerteils, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an electrical connector, comprising a plug part and a mating connector part which can be plugged together with the plug part, and a coupling nut carried by the plug part for screwing the plug part to a threaded sleeve of the mating plug part, according to the preamble of claim 1.

Derartige Steckerbindungen sind allgemein bekannt und werden bevorzugt für elektrische Verbindungen verwendet, die einfach und schnell herstellbar und lösbar sein sollen. Durch die Überwurfmutter werden das Steckerteil und das Gegensteckerteil des Steckverbinders nach dem Zusammenstecken gegen unbeabsichtigtes Trennen gesichert. Hierzu wird üblicherweise die Überwurfmutter, die ein Innengewinde aufweist, auf ein gegenseitiges Außengewinde des Gegensteckerteils bis zu einem axialen Anschlag aufgedreht und anschließend fest angezogen, damit sich die Schraubverbindung nicht lösen kann. Nachteilig bei solchen bekannten Steckverbindern mit Normgewinde ist die benötigte Zeit für ein Befestigen oder Lösen einer derartigen Steckverbindung.Such connectors are well known and are preferably used for electrical connections that should be easy and quick to manufacture and solvable. By the union nut the plug part and the mating connector part of the connector are secured after plugging against accidental disconnection. For this purpose, usually the union nut, which has an internal thread, turned on a mutual external thread of the mating connector part up to an axial stop and then tightened, so that the screw can not solve. A disadvantage of such known connectors with standard thread is the time required for attaching or detaching such a connector.

Zur Behebung dieses Mangels sind weiterhin Steckverbinder bekannt, bei denen das Außengewinde des Gegensteckerteils und das Innengewinde der Überwurfmutter in Steckrichtung vorgesehene gewindefreie und gewindetragende Bereiche aufweisen, die derart ausgebildet und angeordnet sind, dass beim Verbinden des Steckerteils mit dem Gegensteckerteil die gewindetragenden Bereiche in die jeweiligen gewindefreien Bereiche des Steckerteils bzw. des Gegensteckerteils einführbar sind. Nach dem Herstellen der elektrischen Verbindung durch Ineinanderstecken des Steckerteils und des Gegensteckerteils ist der Steckverbinder durch Drehen der Überwurfmutter verriegelbar. Die schnelle Montage oder Demontage wird dadurch erreicht, dass die Überwurfmutter zur Verriegelung maximal um eine Umdrehung gedreht werden muss.To remedy this shortage connectors are still known in which the external thread of the mating connector part and the internal thread of the union nut Have thread-free and threaded portions provided in the insertion direction, which are designed and arranged such that when connecting the plug part with the mating plug part, the threaded portions are inserted into the respective unthreaded portions of the plug part and the mating plug part. After establishing the electrical connection by nesting the male part and the mating connector part of the connector can be locked by turning the nut. Quick assembly or disassembly is achieved by turning the union nut a maximum of one turn for locking.

Ein solcher Steckverbinder wird in der DE 102 33 075 B4 offenbart. Die Patentschrift lehrt einen elektrischen Steckverbinder mit einem eine Gewindehülse ausbildenden Steckerteil zum Aufschrauben einer Überwurfmutter eines mit dem Steckerteil zusammensteckbaren Gegensteckerteils, wobei das Außengewinde der Gewindehülse an seinem Außendurchmesser mindestens einen in Steck- bzw. Aufschraubrichtung vorgesehenen gewindefreien Bereich aufweist, und wobei auf den gewindefreien Bereich des Außengewindes ein daran in seinem Umfang angepasstes Innengewinde der Überwurfmutter einsteckbar und fest drehbar ist.Such a connector is in the DE 102 33 075 B4 disclosed. The patent teaches an electrical connector with a threaded sleeve forming a plug part for screwing a nut of a mating with the plug mating connector part, wherein the external thread of the threaded sleeve has at least one provided in male or screw thread-free area at its outer diameter, and wherein the thread-free area of the external thread an adapted in its circumference internal thread of the nut can be inserted and fixedly rotatable.

Als Nachteil bei dem beschriebenem Steckverbinder wird angesehen, dass es möglich ist, die Überwurfmutter auch bei nicht vollständig zusammengesteckten Steckverbinder zu drehen. In einem solchen Fall können das Steckerteil und das Gegensteckerteil zwar durch mehrmaligen Drehen der Überwurfmutter festgezogen und damit sicher miteinander verriegelt werden, wobei der Vorteil der schnellen Montage und Demontage nicht sichergestellt ist.A disadvantage of the described connector is considered that it is possible to turn the nut even if not completely mated connector. In such a case, although the plug part and the mating connector part can be tightened by repeatedly turning the nut and thus securely locked together, the advantage of quick assembly and disassembly is not guaranteed.

Der Erfindung liegt daher die Aufgabe zugrunde, einen elektrischen Steckverbinder vorzuschlagen, bei dem ein Drehen der Überwurfmutter verhindert wird, solange das Steckerteil und das Gegensteckerteil nicht vollständig zusammengesteckt sind.The invention is therefore the object of providing an electrical connector, in which rotation of the nut is prevented, as long as the plug part and the mating connector part are not completely mated.

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

Bei dem erfindungsgemäßen elektrischen Steckverbinder ist in Steckrichtung vor mindestens einem gewindetragenden Bereich der Überwurfmutter mindestens ein erhabener Ringbundabschnitt angeordnet. Der Ringbundabschnitt greift beim Zusammenstecken des Steckerteils mit dem Gegensteckerteil in den gewindefreien Bereich des Außengewindes der Gewindehülse des Gegensteckerteils ein und ermöglicht ein Drehen der Überwurfmutter erst, wenn der Ringbundabschnitt den gewindefreien Bereich passiert hat. Dann kann die Überwurfmutter zur Verriegelung des Steckverbinders gedreht werden, so dass das Innengewinde der Überwurfmutter und das Außengewinde der Gewindehülse in Eingriff miteinander kommen, wobei der Ringbundabschnitt in Steckrichtung einen, vorzugsweise den letzten Gewindegang des Außengewindes der Gewindehülse hintergreift. Idealerweise ist zur Verriegelung des Steckverbinders maximal eine halbe Umdrehung der Überwurfmutter erforderlich, wodurch ein schnelles Herstellen und Lösen der elektrischen Verbindung sichergestellt ist.In the electrical connector according to the invention at least one raised annular collar portion is arranged in the insertion direction in front of at least one threaded portion of the union nut. The collar portion engages when mating the male part with the mating connector part in the unthreaded region of the external thread of the threaded sleeve of the mating connector part and allows rotation of the nut until the collar portion has passed the unthreaded region. Then, the union nut can be rotated to lock the connector, so that the internal thread of the union nut and the external thread of the threaded sleeve come into engagement with each other, wherein the collar portion in the insertion direction engages behind one, preferably the last thread of the external thread of the threaded sleeve. Ideally, a maximum of half a turn of the union nut is required to lock the connector, whereby a rapid establishment and release of the electrical connection is ensured.

Vorteilhafterweise weisen der Ringbundabschnitt und der gewindetragende Bereich des Innengewindes in Umfangsrichtung der Überwurfmutter eine identische Länge auf und fluchten miteinander. Damit ist sichergestellt, dass die Gewindegänge des Innengewindes der Überwurfmutter und des Außengewindes der Gewindehülse beim Zusammenstecken des Steckerteil mit dem Gegensteckerteil nicht unbeabsichtigt seitlich geringfügig in Eingriff gelangen können und ein schnelles Zusammenstecken verhindern. Selbiges gilt für das Trennen der Steckverbindung.Advantageously, the annular collar portion and the threaded portion of the internal thread in the circumferential direction of the union nut on an identical length and are aligned with each other. This ensures that the threads of the internal thread of the union nut and the external thread of the threaded sleeve during mating of the connector part with the mating connector part can not accidentally engage slightly laterally and prevent rapid mating. The same applies to the disconnection of the connector.

Vorzugsweise weist der Ringbundabschnitt und der gewindetragende Bereich der Überwurfmutter in Steckrichtung eine identische Kontur auf. Dies wirkt sich günstig auf die Prozesszeit bei der Herstellung der Gewindemutter aus und reduziert damit die entsprechenden Stückkosten.Preferably, the annular collar portion and the threaded portion of the union nut in the insertion direction on an identical contour. This has a favorable effect on the process time during the production of the threaded nut and thus reduces the corresponding unit costs.

In einer bevorzugten Ausführungsform der Erfindung ist in Steckrichtung hinter einem Gewindegang des gewindetragenden Bereichs des Gegensteckerteils ein Aufnahmeraum für den Ringbundabschnitt der Überwurfmutter vorgesehen. Der Aufnahmeraum kann in dem gewindetragenden Bereich zwischen den Gewindegängen oder nach den Gewindegängen angeordnet sein. Abhängig von seiner Anordnung ist er einseitig oder zweiseitig von einem Gewindegang begrenzt. Vorzugsweise ist der Aufnahmeraum im Anschluss an den in Steckrichtung letzten Gewindegang der Gewindehülse ausgebildet, wobei er von einem umlaufenden Ringbund an einer dem Außengewinde abgewandten Seite begrenzt sein kann. Der Aufnahmeraum muss eine Breite aufweisen, die größer ist als Dicke des Ringbundabschnittes in Steckrichtung, wobei die Dicke des Ringbundabschnitts im wesentlichen von der Gewindesteigung der Gewinde der Überwurfmutter bzw. der Gewindehülse bestimmt ist und mindestens einem 1fachen, vorzugsweise 2fachen eines Gewindeganges (Gewindesteigung, Gewindeteilung) entspricht.In a preferred embodiment of the invention, a receiving space for the annular collar portion of the union nut is provided in the insertion direction behind a thread of the threaded portion of the mating connector part. The receiving space can be arranged in the thread-carrying area between the threads or after the threads. Depending on its arrangement, it is bounded on one or both sides by a thread. Preferably, the receiving space is formed following the last thread in the insertion direction of the threaded sleeve, wherein it may be bounded by a circumferential annular collar on a side facing away from the external thread side. The receiving space must have a width which is greater than the thickness of the annular collar portion in the insertion direction, wherein the thickness of the collar portion is determined substantially by the thread pitch of the threads of the nut or the threaded sleeve and at least a 1, preferably 2 times a thread turn (thread pitch, thread pitch ) corresponds.

In einer Ausgestaltung der Erfindung ist der Ringbundabschnitt parallel zu den Gewindegängen des Innengewindes angeordnet und als Gewindegangabschnitt ausgebildet. Der Gewindegangabschnitt kann dabei entsprechend der Form eines Spitzgewindes, Flachgewindes oder als Trapezgewindes ausgebildet und für einen Eingriff in einen korrespondierenden Gewindeabschnitt des Aufnahmeraumes vorgesehen sein. Wichtig ist dabei, das der als Gewindegang ausgebildete Ringbundabschnitt eine mit den Gewindegängen der Gewindehülse und der Überwurfmutter identische Steigung oder Teilung, bei unterschiedlicher Querschnittsform, aufweist.In one embodiment of the invention, the annular collar portion is arranged parallel to the threads of the internal thread and formed as a thread section. The thread portion may be formed corresponding to the shape of a pointed thread, flat thread or a trapezoidal thread and provided for engagement in a corresponding threaded portion of the receiving space. It is important that the formed as a thread collar portion has an identical with the threads of the threaded sleeve and the union pitch or pitch, with different cross-sectional shape.

In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Steckverbinders ist eine in Umfangsrichtung gemessene Länge des gewindetragenden Bereiches des Außengewindes der Gewindehülse ein Mehrfaches des gewindetragenden Bereiches des Innengewindes der Überwurfmutter. Damit ist der gewindetragende Bereich der Überwurfmutter deutlich kürzer als der gewindetragende Bereich der Gewindehülse ausgebildet, was beim Drehen der Überwurfmutter eine optimale Überdeckung in Umfangsrichtung zur Folge hat. Auf diese Weise sind beim Drehen der Überwurfmutter das Innengewinde und das Außengewinde über einen großen Umfangsbereich miteinander in Eingriff, bevor die gewindetragenden Bereiche wieder außer Eingriff kommen.In an advantageous embodiment of the connector according to the invention, a circumferentially measured length of the threaded portion of the external thread of the threaded sleeve is a multiple of the threaded portion of the internal thread of the union nut. Thus, the threaded portion of the nut is formed significantly shorter than the threaded portion of the threaded sleeve, which has an optimal coverage in the circumferential direction when turning the nut. In this way are at Turning the union nut, the female thread and the male thread engage over a large circumferential area with each other before the threaded portions are disengaged again.

Abhängig von der Gewindesteigung der gewindetragenden Bereiche können damit große Toleranzen des Gegensteckerteils weitgehend ausgeglichen werden, beispielsweise eine in Steckrichtung unterschiedliche Position des gewindetragenden Bereiches des Gegensteckerteils gegenüber einer dem Steckerteil zugewandten Stirnseite der Gewindehülse. Dies stellt sicher, dass nach dem Festdrehen der Überwurfmutter die Gewindehülse mit ihrer Stirnseite an eine der Stirnseite zugeordnete Stirnseite des Steckerteils angelegt und angepresst ist.Depending on the thread pitch of the threaded portions so that large tolerances of the mating connector part can be largely compensated, for example, a different direction in the insertion direction of the threaded portion of the mating connector against a plug part facing the front side of the threaded sleeve. This ensures that after tightening the nut the threaded sleeve is applied and pressed with its end face to one of the front side associated end face of the plug part.

Besonders zweckmäßig erscheint eine Ausführungsform mit je zwei gewindetragenden und gewindefreien Bereichen, wobei die gewindetragenden Bereiche ein Längenverhältnis in Umfangsrichtung von mindestens 3:1 aufweisen. Bei mehr als zwei gewindefreien Bereichen, und/oder einem deutlich kleineren Längenverhältnis ist eine optimale Überdeckung über eine weiten Umfangsbereich beim Drehen der Überwurfmutter nicht sichergestellt.Particularly expedient appears an embodiment with two thread-carrying and thread-free areas, wherein the thread-carrying areas have an aspect ratio in the circumferential direction of at least 3: 1. With more than two unthreaded areas, and / or a much smaller aspect ratio optimal coverage over a wide peripheral area when turning the nut is not guaranteed.

Der erfindungsgemäße Steckverbinder weist mindestens je einen in Steckrichtung vorgesehenen gewindefreien Bereich und mindestens einen daran in Umfangsrichtung anschließenden gewindetragenden Bereich auf, die derart ausgebildet und angeordnet sind, dass beim Zusammenstecken des Steckerteils mit dem Gegensteckerteil die jeweiligen gewindetragenden Bereiche in die zugeordneten gewindefreien Bereiche des Stecker- bzw. Gegensteckerteils in Steckrichtung einführbar sind. Insbesondere können an dem Steckerteil und dem Gegensteckerteil jeweils zwei gewindefreie und gewindetragende Bereiche für das Innengewinde der Überwurfmutter bzw. das Außengewinde der Gewindehülse vorgesehen sein, so dass die Überwurfmutter beim Aufschrauben auf die Gewindehülse nicht verkantet.The plug-in connector according to the invention has at least one thread-free region provided in the plug-in direction and at least one thread-carrying region adjoining it in the circumferential direction, which are designed and arranged such that when the plug part is mated with the mating plug part, the respective thread-carrying regions are inserted into the associated unthreaded regions of the plug connector. or mating connector part can be inserted in the insertion direction. In particular, two thread-free and threaded portions for the internal thread of the nut or the external thread of the threaded sleeve may be provided on the plug part and the mating plug part, so that the nut does not tilt when screwed onto the threaded sleeve.

Das Gegensteckerteil kann ein geschnittenes oder ein gegossenes Gewinde aufweisen. Bei einem gegossenen Gewinde können die zwei herstellungsbedingten abgeflachten Gewindeflächen als gewindefreie Bereiche im Sinne der Erfindung verstanden werden. Typisch erstrecken sich dabei in etwa die gewindetragenden Bereiche des Außengewindes über je 135° und dessen gewindefreie Bereiche über je 45°. Damit sind 75% des Umfangs des Außengewindes als gewindetragender Bereich und 25% als gewindefreier Bereich ausgebildet. Entsprechend umgekehrt ist das Verhältnis bei dem Umfang des Innengewindes der Überwurfmutter. Damit kann die Überwurfmutter für die Verriegelung um circa 135°, bei vollständiger Überdeckung der gewindetragenden Bereiche der Überwurfmutter des Steckerteils und der Gewindehülse des Gegensteckerteils, gedreht werden.The mating connector part may have a cut or a cast thread. In a cast thread, the two production-related flattened thread surfaces are understood as thread-free areas in the context of the invention. Typically, the thread-carrying areas of the external thread each extend over 135 ° and its thread-free areas over 45 °. Thus, 75% of the circumference of the external thread is formed as a thread-carrying area and 25% as a thread-free area. Correspondingly reversed, the ratio in the circumference of the internal thread of the union nut. Thus, the union nut for locking by about 135 °, with complete coverage of the threaded portions of the nut of the male part and the threaded sleeve of the mating connector part, rotated.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Steckverbinders ist zwischen einer die Überwurfmutter tragenden Befestigungshülse des Steckerteils und der Überwurfmutter ein gummielastisches Ringelement angeordnet ist. Das Ringelement ist von der Überwurfmutter übergriffen und gepresst und wirkt als Reibungsbremse. Die Reibungsbremse beaufschlagt die Überwurfmutter in jeder Stellung bezüglich der Befestigungshülse. Die Hemmung der Drehbewegung erfolgt somit unabhängig von der Überdeckung in Steckrichtung des Innengewindes der Überwurfmutter mit dem Außengewinde der Gewindehülse des Gegensteckerteils. Dies bewirkt, dass nach der drehenden Verriegelung des elektrischen Steckverbinders, auch bei nicht festgezogener Überwurfmutter, d.h. wenn die Stirnseiten der Gewindehülse und der Befestigungshülse nicht aneinander gepresst sind, einen gewissen Schutz vor einer ungewollten Trennung des Steckerteils von dem Gegensteckerteil des elektrischen Steckverbinders. Das gummielastische Ringelement verhindert ein ungewolltes Lösen der Überwurfmutter durch Vibrationen und Erschütterungen und kann zudem den Steckerver-binder gegen Umwelteinflüsse abdichten.In a preferred embodiment of the connector according to the invention, a rubber-elastic ring element is arranged between a nut carrying the fastening sleeve of the plug part and the union nut. The ring element is overlapped and pressed by the union nut and acts as a friction brake. The friction brake acts on the union nut in any position with respect to the fastening sleeve. The inhibition of the rotational movement is thus independent of the overlap in the insertion direction of the internal thread of the union nut with the external thread of the threaded sleeve of the mating connector part. This causes after the rotating locking of the electrical connector, even with not tightened union nut, i. if the faces of the threaded sleeve and the mounting sleeve are not pressed together, some protection against accidental separation of the male part of the mating connector part of the electrical connector. The rubber-elastic ring element prevents unwanted loosening of the union nut by vibrations and shocks and can also seal the Steckerver-binder against environmental influences.

Der in den Figuren 1, 2 dargestellte, erfindungsgemäße elektrische Steckverbinder 1 umfasst ein längliches Steckerteil 2 mit einer Überwurfmutter 3 und ein Gegensteckerteil 4, das im Ausführungsbeispiel als Winkelflansch ausgebildet ist. Die Überwurfmutter 3 ist an dem Steckerteil 2 drehbar befestigt und dient zum Aufschrauben auf eine Gewindehülse 5 des Gegensteckerteils 4. Das Steckerteil 2 kann ausschließlich in der in Figur 1 dargestellten Stellung der Überwurfmutter 3 bezüglich dem Korpus 6 des Steckerteils 2 mit dem Gegensteckerteil 4 zusammengesteckt werden. Im zusammengesteckten Zustand können das Steckerteil 2 und das Gegensteckerteil 4 durch Drehen der Überwurfmutter 3, um maximal 135°, miteinander verriegelt werden.The in the FIGS. 1, 2 illustrated, electrical connector 1 according to the invention comprises an elongated plug part 2 with a union nut 3 and a mating connector part 4, which is formed in the embodiment as an angle flange. The union nut 3 is rotatably mounted on the plug part 2 and is used for screwing on a threaded sleeve 5 of the mating connector part 4. The plug part 2 can only in the in FIG. 1 shown position of the union nut 3 with respect to the body 6 of the male part 2 are mated with the mating connector part 4. In the assembled state, the plug part 2 and the mating connector part 4 by turning the nut 3, by a maximum of 135 °, are locked together.

Das Gegensteckerteil 4 weist einen Kontaktträger 7 mit Kontaktelementen 8 und eine Codiereinrichtung 9 auf, die komplementär an den Steckerteil 2 vorgesehen, jedoch in der Zeichnung nicht dargestellt sind. Ein Verbinden des Steckerteils 2 mit dem Gegensteckerteil 4 des Steckverbinders 1 ist nur bei miteinander fluchtenden Codiereinrichtungen möglich, die jedoch beim Zusammenstecken des Steckverbinders 1 durch die Überwurfmutter 3 verdeckt sind. Zum einfachen Ausrichten des Steckerteils 2 bezüglich dem Gegensteckerteil 4 sind jeweils an dem Außenumfang des Steckerteils 2 und des Gegensteckerteils 4 entsprechende Markierungen 10, 10' vorgesehen.The mating plug part 4 has a contact carrier 7 with contact elements 8 and an encoder 9, which are provided complementary to the plug part 2, but not shown in the drawing. A connection of the plug part 2 with the mating connector part 4 of the connector 1 is only possible with mutually aligned coding devices, however, when mating the Connector 1 are covered by the union nut 3. For easy alignment of the plug part 2 with respect to the mating plug part 4 corresponding marks 10, 10 'are respectively provided on the outer periphery of the plug part 2 and the mating plug part 4.

Zum Verschrauben des Steckerteils mit dem Gegensteckerteil 4 sind an der Gewindehülse 5 ein Außengewinde 11 und an der Überwurfmutter 3 ein an das Außengewinde 11 angepasstes Innengewinde 12 vorgesehen. Wie aus den Figuren 3a, b ersichtlich, weisen das Außengewinde 11 und das Innengewinde 12 je zwei gewindefreie Bereiche 13 bzw. 14 und zwei gewindetragende Bereiche 15 bzw. 16 auf. Die in Umfangsrichtung gemessene Länge des gewindetragenden Bereichs 15 der Gewindehülse 5 entspricht im Wesentlichen der ebenfalls in Umfangsrichtung gemessenen Länge des gewindefreien Bereichs 14 der Überwurfmutter 3. Entsprechend sind die Längen der gewindetragenden Bereiche 12 der Überwurfmutter 3 und die gewindefreien Bereiche 13 der Gewindehülse 5 zueinander ausgebildet. Dies ermöglicht, dass beim Zusammenstecken des Steckerteils 2 mit dem Gegensteckerteil 4 die gewindetragenden Bereiche 15, 16 in die jeweiligen zugeordneten gewindefreien Bereiche 13, 14 der Gewindehülse 5 bzw. der Überwurfmutter 3 in Steckrichtung mit geringem Spiel ineinander einführbar sind.For screwing the male part with the mating connector part 4, an external thread 11 and on the union nut 3 to the external thread 11 adapted internal thread 12 are provided on the threaded sleeve 5. Like from the FIGS. 3a, b can be seen, the external thread 11 and the internal thread 12 each have two unthreaded regions 13 and 14 and two threaded portions 15 and 16, respectively. The circumferentially measured length of the threaded portion 15 of the threaded sleeve 5 substantially corresponds to the also measured in the circumferential direction length of the unthreaded portion 14 of the union nut 3. Accordingly, the lengths of the threaded portions 12 of the union nut 3 and the unthreaded portions 13 of the threaded sleeve 5 are formed to each other , This allows that when mating the plug part 2 with the mating connector part 4, the threaded portions 15, 16 in the respective associated thread-free areas 13, 14 of the threaded sleeve 5 and the nut 3 in the insertion direction with little play are inserted into each other.

Ein Zusammenstecken des Steckerteils 2 mit dem Gegensteckerteil 4 ist nur möglich, wenn die gewindefreien Bereiche 13, 14 mit den entsprechenden gewindetragenden Bereichen 15, 16 fluchten. Zur einfachen in Umfangsrichtung lagegenauen Positionierung der Überwurfmutter bezüglich dem Steckerteil 2 und dem Gegensteckerteil 4 weist die Überwurfmutter eine Einstellmarkierung 17 auf, die für das Zusammenstecken, wie in Figur 2 dargestellt, den Markierungen 10, 10' des Steckerteils 2 bzw. des Gegensteckerteils 4 gegenüberliegen muss und durch einen Anschlag festgelegt ist.A mating of the plug part 2 with the mating connector part 4 is only possible if the unthreaded areas 13, 14 are aligned with the corresponding threaded portions 15, 16. For simple in the circumferential direction positionally accurate positioning of the union nut with respect to the plug part 2 and the mating connector part 4, the union nut has a Einstellmarkierung 17, for the mating, as in FIG. 2 shown, the markers 10, 10 'of the plug part 2 and the counter plug part 4 must be opposite and is determined by a stop.

Das Innengewinde 12 und das Außengewinde 11 sind bei dem in der Zeichnung dargestellten Ausführungsbeispiels des erfindungsgemäßen Steckverbinders als Spitzgewinde mit je vier Gewindegängen 18 bzw. 19 ausgeführt. Die Gewinde 11, 12 weisen je zwei gewindetragende Bereiche 15 bzw. 16 und je zwei gewindefreie Bereiche 13 bzw. 14 auf, die in Umfangsrichtung symmetrisch an der Überwurfmutter 3 bzw. der Gewindehülse 5 angeordnet sind. Die in Umfangsrichtung gemessene Länge des gewindetragenden Bereichs 16 des Innengewindes 12 beträgt in etwa 1/3 der Länge des zugeordneten gewindetragenden Bereiches 15 des Außengewindes 11. Entsprechend sind die gewindefreien Bereiche 13, 14 der Gewindehülse 5 und der Überwurfmutter 3 ausgebildet. Damit sind die Gewindegänge 18 des Innengewindes 12 beim Drehen der Überwurfmutter 3 über einen Drehwinkel von nahezu 135°, bei vollständiger radialer Überdeckung, mit den Gewindegängen 19 des Außengewindes 11 in Eingriff. Dies ermöglicht eine entsprechende, allein von der Gewindesteigung abhängige, vergrößerte Bewegungmöglichkeit der Überwurfmutter 3 in Steckrichtung und damit den Ausgleich größer Toleranzen des Gegensteckerteils 4.The internal thread 12 and the external thread 11 are executed in the embodiment of the connector according to the invention shown in the drawing as a pointed thread with four threads 18 and 19 respectively. The threads 11, 12 each have two threaded portions 15 and 16 and two thread-free portions 13 and 14, which are arranged symmetrically in the circumferential direction of the union nut 3 and the threaded sleeve 5. The circumferentially measured length of the threaded portion 16 of the internal thread 12 is approximately 1/3 of the length of the associated threaded portion 15 of the external thread 11. Accordingly, the unthreaded portions 13, 14 of the threaded sleeve 5 and the union nut 3 are formed. Thus, the threads 18 of the internal thread 12 when turning the nut 3 over a rotation angle of almost 135 °, with complete radial overlap, with the threads 19 of the external thread 11 into engagement. This allows a corresponding, solely dependent on the thread pitch, increased movement possibility of the union nut 3 in the insertion direction and thus the compensation of larger tolerances of the mating connector part. 4

Wie aus den Figuren 3b, 4 ersichtlich, ist in Steckrichtung vor dem gewindetragenden Bereich der Überwurfmutter 3 ein erhabener Ringbundabschnitt 20 angeordnet, der in Steckrichtung gesehen eine zu den Gewindegängen 18 identische Kontur aufweist. Der Ringbundabschnitt 20 erstreckt sich in Steckrichtung um etwa zwei Gewindegänge 18 und verhindert ein Drehen der Überwurfmutter 3 während des Zusammensteckens des Steckerteils 2 mit dem Gegensteckerteil 4, solange der Ringbundabschnitt 20 in dem gewindefreien Bereich 13 des Außengewindes 11 der Gewindehülse 5, d.h. zwischen die beiden gewindetragenden Bereiche 15, eingreift. Erst wenn der Ringbundabschnitt 20 beim Zusammenstecken des Steckerteils 2 mit dem Gegensteckerteil 4 nicht mehr zwischen den gewindefreien Bereichen 13 des Außengewindes 11 der Gewindehülse 5 einliegt, lässt sich die Überwurfmutter 3 zum Verriegeln des Steckverbinders 1 in Umfangsrichtung drehen.Like from the FIGS. 3b, 4 can be seen, a raised collar portion 20 is arranged in the insertion direction in front of the threaded portion of the union nut 3, seen in the insertion direction has an identical to the threads 18 contour. The annular collar portion 20 extends in the insertion direction by about two threads 18 and prevents rotation of the union nut 3 during the mating of the male part 2 with the mating connector part 4, as long as the annular collar portion 20 in the unthreaded region 13 of the external thread 11 of the threaded sleeve 5, ie between the two threaded portions 15, engages. Only when the annular collar portion 20 no longer rests between the unthreaded regions 13 of the external thread 11 of the threaded sleeve 5 during mating of the connector part 2 with the mating connector part 4, the union nut 3 can be rotated to lock the connector 1 in the circumferential direction.

Für den Ringbundabschnitt 20 ist anschließend an das Außengewinde 11 an der Gewindehülse 5 ein ringförmiger Aufnahmeraum 21 ausgebildet, der in Steckrichtung von einem Ringbund 22 begrenzt ist. Die Breite des Aufnahmeraumes 21 beträgt in etwa das 2,5fache der Steigung des Außengewindes 11. Beim Drehen hintergreift der Ringbundabschnitt 20 der Überwurfmutter 3 den gewindetragenden Bereich 15 des Gegensteckerteils 4 und wird mit der Bewegung der Überwurfmutter 3 in Steckrichtung zu dem Ringbund 22 der Gewindehülse 5 hin bewegt.For the annular collar portion 20, an annular receiving space 21 is subsequently formed on the external thread 11 on the threaded sleeve 5, which is bounded in the insertion direction by a collar 22. The width of the receiving space 21 is approximately 2.5 times the pitch of the external thread 11. When turning engages the annular collar portion 20 of the union nut 3, the threaded portion 15 of the mating connector part 4 and is moved with the movement of the union nut 3 in the insertion direction to the annular collar 22 of the threaded sleeve 5 out.

Zwischen der Überwurfmutter 3 und einer Befestigungshülse 23 des Steckerteils 2, an der die Überwurfmutter 3 drehbar befestigt ist, ist in Steckrichtung hinter dem Innenwinde 12 der Überwurfmutter 3 ein O-Ring als gummielastisches Ringelement 24 angeordnet. Der in einer Nut einliegende O-Ring 24 ist, wie in der Figur 4 dargestellt, von der Überwurfmutter 3 übergriffen und gepresst. Der von der Überwurfmutter 3 elastische verformte O-Ring 24 wirkt als Rüttel- bzw. Vibrationsbremse für den Steckverbinder 1 und verhindert ein ungewolltes Lösen des Steckerteils 2 von dem Gegensteckerteil 4 und damit ein Trennen des elektrischen Steckverbinders 1 durch Reibungskraft.Between the union nut 3 and a mounting sleeve 23 of the connector part 2, to which the union nut 3 is rotatably mounted, an O-ring is arranged as rubber-elastic ring element 24 in the insertion direction behind the internal winds 12 of the union nut 3. The inset in a groove O-ring 24 is, as shown in Figure 4, overlapped and pressed by the union nut 3. The elastic of the union nut 3 deformed O-ring 24 acts as Rüttel- or vibration brake for the connector 1 and prevents accidental release of the connector part 2 of the mating connector part 4 and thus disconnecting the electrical connector 1 by frictional force.
