Description

Die Erfindung betrifft ein Steckerelement gemäß Gattungsbegriff des Anspruchs 1.The invention relates to a plug element according to the preamble of claim 1.

Ein gattungsgemäßes Steckerelement wird von der EP 1 626 463 B1 beschrieben. Das Steckerelement besitzt einen Tragkörper, auf dem eine Überwurfmutter angeordnet ist. Die Überwurfmutter wirkt mit einem Gewindeeingriffsteil zusammen. Wird die Überwurfmutter gedreht, so wird das Gewindeeingriffsteil relativ gegenüber dem Kontaktträger verlagert. Die Gewindevorsprünge des Gewindeeingriffsteils gleiten dabei auf Verdickungen am Trägkörper auf und werden dadurch in Radialrichtung in eine Gewindeeingriffsstellung verlagert.A generic plug element is of the EP 1 626 463 B1 described. The plug element has a support body on which a union nut is arranged. The union nut cooperates with a threaded engagement part. If the union nut is rotated, the threaded engagement member is displaced relative to the contact carrier. The thread projections of the threaded engagement member slide on thickening on the support body and are thereby displaced in the radial direction in a threaded engagement position.

Die EP 1 603 200 A1 beschreibt ein Steckerelement mit von Zungen getragenen Gewindevorsprüngen, welche ebenfalls durch Verlagern einer Betätigungshülse in Radialrichtung in eine Gewindeeingriffsstellung verlagert werden.The EP 1 603 200 A1 describes a male member with tongue projections threaded projections, which are also displaced by displacing an actuating sleeve in the radial direction in a threaded engagement position.

Aus der DE 10 2004 028 060 A1 sind verschiedene Ausführungsformen eines Steckerelementes bekannt, welches mit einem Gegensteckerelement zusammengesteckt werden kann. Durch eine daran anschließende Axialverlagerung einer Betätigungshülse werden Gewindeeingriffsvorsprünge in ein Gegengewinde eines Gegensteckerelementes gebracht. Durch ein anschließendes Verdrehen der Betätigungshülse kann eine Dichtung in Form eines Dichtringes komprimiert werden. Die Gewindeeingriffsvorsprünge werden dort von Federzungen getragen, die durch axiales Verlagern der Betätigungshülse gegen ihre Federspannung von der Freigabestellung in die Verriegelungsstellung verlagert werden. Die Federzungen sind an einem ringförmig den Kontaktträger umgebenden Federzungenträger einstückig angeformt und bestehen aus Metall.From the DE 10 2004 028 060 A1 Various embodiments of a plug element are known, which can be plugged together with a mating connector element. By an adjoining axial displacement of an actuating sleeve threaded engagement projections are brought into a mating thread of a mating connector element. By a subsequent rotation of the actuating sleeve, a seal in the form of a sealing ring can be compressed. The threaded engagement projections are supported there by spring tongues, which are displaced by axial displacement of the actuating sleeve against its spring tension from the release position into the locking position. The spring tongues are integrally formed on a ring-shaped surrounding the contact carrier spring tongue carrier and are made of metal.

Aus der DE 198 14 334 A1 ist ein Stecker bekannt, der mit einem Gegensteckerelement im Wege einer Schnellverriegelung verbunden werden kann. Auch hier werden durch Betätigen einer Betätigungshülse Federzungen im Wesentlichen radial zur Achse des Steckerelementes verlagert. Verriegelungsvorsprünge treten in zugeordnete Verriegelungsnuten.From the DE 198 14 334 A1 a plug is known, which can be connected to a mating connector element by means of a quick-lock. Again, by operating an actuating sleeve spring tongues are displaced substantially radially to the axis of the plug element. Locking projections enter associated locking grooves.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Steckerelement gebrauchsvorteilhaft weiterzubilden.The invention has for its object to further develop a generic connector element nutzsvorteilhaft.

Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung, wobei unabhängiger Anspruch d eine eigenständige Lösung der Aufgabe darstellt und mit jedem abhängigen Anspruch beliebig kombinierbar ist.The object is achieved by the invention specified in the claims, wherein independent claim d represents an independent solution to the problem and can be combined with any dependent claim.

Erfindungsgemäß hat die Betätigungshülse Betätigungsarme. Diese Betätigungsarme ragen axial von der Betätigungshülse ab. An den Enden der Betätigungsarme sind Hubflächen angeordnet. Bei den Hubflächen kann es sich um Keilflächen handeln. Diese greifen an mehreren Umfangsstellen unter die Gewindeeingriffsvorsprünge, um sie beim Verlagern der Betätigungshülse in die Gewindeeingriffsstellung zu bringen. Dabei werden die Gewindeeingriffsvorsprünge in Radialrichtung verlagert. Es sind bevorzugt mindestens drei in Umfangsrichtung gleichmäßig verteilte Betätigungsarme vorgesehen. Diese Betätigungsarme können zwischen den Federzungen angeordnet sein, die an ihren freien Enden die Gewindeeingriffsvorsprünge tragen. Die Gewindeeingriffsvorsprünge können von Bogenstücken ausgebildet sein. Diese Bogenstücke umgeben in Umfangsrichtung jeweils teilweise den Kontaktträger. Die Bogenstücke sind bevorzugt voneinander in Umfangsrichtung beabstandet und bilden gegenüber den Federzungen seitliche Überstände aus. Die keilförmig schrägen Hubflächen können unter diese Überstände greifen, wenn die Betätigungshülse in Achsrichtung von der Freigabestellung und Verriegelungsstellung verlagert wird. Die Gewindeeingriffsvorsprünge gleiten dann auf den schrägen Hubflächen auf, um radial entweder nach außen oder nach innen verlagert zu werden. Die Betätigungsarme können darüber hinaus Keilstücke ausbilden, die sich beim Verlagern der Betätigungshülse zwischen die Bogenstücke schieben, um sie dann umfangsvergrößernd zu verlagern bzw. lagezustabilisieren. Die Betätigungshülse ist drehfest aber axialverschieblich dem Federzungenträger zugeordnet. Der Federzungenträger kann lediglich drehbar dem Kontaktträger zugeordnet sein. Zufolge dieser Ausgestaltung kann in der Freigabestellung das Steckerelement mit einem Gegensteckerelement zusammengesteckt werden. Bei dem Steckerelement kann es sich um einen männlichen oder um einen weiblichen Stecker handeln. Sind die beiden Steckerelemente zusammengesteckt, wird die Betätigungshülse in Achsrichtung verlagert. Dies hat zur Folge, dass sich die Gewindeeingriffsvorsprünge in Radialrichtung in Richtung auf das Gegengewinde zu bewegen. Sie können dabei je nach Ausführung des Steckerelementes entweder radial nach außen verlagert werden, um in ein Innengewinde des Gegensteckerelementes einzutreten, oder sie können radial nach innen verlagert werden, um in ein Außengewinde des Steckerelementes eingreifen zu können. Bei dieser Verlagerung löst sich die Betätigungshülse von einer ersten Raststellung, in welcher sie in der Freigabestellung gehalten ist und tritt in eine zweite Raststellung ein, in welcher sie in der Verriegelungsstellung gehalten ist, in welcher die Gewindeeingriffsvorsprünge in den Gewindegängen des Gegengewindes einliegen. Eine dann erfolgende Drehung der Betätigungshülse schleppt das Gewindeeingriffsteil und damit die Gewindeeingriffsvorsprünge mit. Ein zwischen Steckerelement und Gegensteckerelement liegender Dichtring wird bei dieser Schraubbewegung komprimiert.According to the invention the actuating sleeve actuating arms. These actuating arms protrude axially from the actuating sleeve. At the ends of the actuating arms lifting surfaces are arranged. The lifting surfaces may be wedge surfaces. These engage at several circumferential locations under the threaded engagement projections to bring them in displacing the actuating sleeve in the threaded engagement position. The threaded engagement projections are displaced in the radial direction. There are preferably provided at least three circumferentially uniformly distributed actuating arms. These actuating arms can be arranged between the spring tongues, which carry at their free ends, the threaded engagement projections. The threaded engagement projections may be formed by elbows. These elbows partially surround the contact carrier in the circumferential direction. The curved pieces are preferably spaced apart from one another in the circumferential direction and form lateral projections with respect to the spring tongues. The wedge-shaped oblique lifting surfaces can engage under these projections when the actuating sleeve in the axial direction of the release position and locking position is relocated. The threaded engagement projections then slide on the inclined lifting surfaces to be displaced radially either outwardly or inwardly. The actuating arms can also form wedge pieces that slide during the displacement of the actuating sleeve between the elbows in order to then displace them circumferentially or stabilize the position. The actuating sleeve is rotatably but axially displaceable associated with the spring tongue carrier. The spring tongue carrier can only be assigned rotatably to the contact carrier. According to this embodiment, the plug element can be plugged together with a mating connector element in the release position. The plug element may be a male or a female plug. If the two plug elements are plugged together, the actuating sleeve is displaced in the axial direction. As a result, the threaded engagement projections move radially toward the mating thread. Depending on the design of the plug element, they can either be displaced radially outwards in order to enter an internal thread of the mating plug element, or they can be displaced radially inwards in order to be able to engage in an external thread of the plug element. In this displacement, the actuating sleeve releases from a first detent position in which it is held in the release position and enters a second detent position in which it is held in the locking position in which the threaded engagement projections in the threads of the counter thread einliegen. A subsequent rotation of the actuating sleeve entrains the threaded engagement portion and thus the threaded engagement projections. A lying between the male element and mating connector sealing ring is compressed in this screwing movement.

Das in den Figuren 1 bis 8 dargestellte Ausführungsbeispiel besitzt einen Kontaktträger 3, der eine Einstecköffnung 33 für ein Gegensteckerelement 2 aufweist, welches einen entsprechenden Einstecksockel 35 ausbildet. Das Gewindeingriffsteil 7 besitzt mehrere Federzungen 8. Die insgesamt drei in gleichmäßiger Umfangsverteilung angeordneten und sich in Axialrichtung erstreckenden Federzungen 8 sind materialeinheitlich an einem ringförmigen Federzungenträger 9 befestigt. Eine der Federzungen 8 bildet im Bereich des Federzungenträgers 9 einen Axialschlitz 32 aus. Der Federzungenträger ist hierzu ebenfalls geschlitzt. Der Schlitz 32 ist an seinem Rand von einer U-förmigen Rastrippe 26 umgeben. Die beiden voneinander wegweisenden Umfangsflanken der Rastrippe 26 bilden nebeneinanderliegende Rastaussparungen 12 aus. Zufolge des Schlitzes 32 können sich die beiden U-Schenkel der Rastrippe 26 geringfügig aufeinander zu bewegen.That in the FIGS. 1 to 8 illustrated embodiment has a contact carrier 3, which has an insertion opening 33 for a mating connector element 2, which forms a corresponding plug socket 35. The threaded engagement member 7 has a plurality of spring tongues 8. The total of three arranged in a uniform circumferential distribution and extending in the axial direction of the spring tongues 8 are of the same material attached to an annular spring tongue carrier 9. One of the spring tongues 8 forms an axial slot 32 in the region of the spring tongue carrier 9. The spring tongue carrier is also slotted for this purpose. The slot 32 is at its edge by a U-shaped locking rib 26 surrounded. The two mutually pioneering peripheral edges of the locking rib 26 form adjacent locking recesses 12. As a result of the slot 32, the two U-legs of the locking rib 26 can move slightly towards each other.

Die Betätigungshülse 4 besitzt axial abragende Betätigungsarme 27. Es sind insgesamt drei Betätigungsarme 27 vorgesehen, die in den Zwischenräumen der in Umfangsrichtung voneinander beabstandeten Federzungen 8 liegen. Im Bereich eines Zwischenraumes zwischen zwei Betätigungsarmen 27 besitzt die Innenwandung der Betätigungshülse 4 Führungsstege 31, zwischen denen die U-förmige Rastrippe 26 liegt. Von den beiden einen entsprechenden Abstand aufweisenden Führungsstegen 31 ragen Rastnasen 13 ab. Die Rastnasen 13 ragen aufeinander zugerichtet derart von den Führungsstegen 31 ab, dass sie in die beiden nebeneinanderliegenden Rastaussparungen 12 der Rastrippe 26 eintreten können.The actuating sleeve 4 has axially projecting actuating arms 27. There are a total of three actuating arms 27 are provided, which lie in the interstices of circumferentially spaced spring tongues. In the region of an intermediate space between two actuating arms 27, the inner wall of the actuating sleeve 4 has guide webs 31, between which the U-shaped locking rib 26 lies. Of the two a corresponding distance having guide webs 31 protrude locking lugs 13 from. The detents 13 protrude toward one another in such a way from the guide webs 31, that they can enter into the two adjacent locking recesses 12 of the locking rib 26.

Die Betätigungshülse 4 kann gegenüber dem Gewindeingriffsteil 7 in Achsrichtung verlagert werden, wobei die beiden Verlagerungspositionen durch Eingriff der beiden Rastnasen 13 in die jeweiligen Rastaussparungen 12 fixiert sind.The actuating sleeve 4 can be displaced in the axial direction relative to the threaded engagement part 7, wherein the two displacement positions are fixed by engagement of the two locking lugs 13 in the respective locking recesses 12.

Die Stirnseiten der Betätigungsarme 27 besitzen zwei jeweils am Rand angeordnete Schrägflächen 28, die Hubflächen ausbilden. Zwischen den beiden Hubflächen 28 bildet die Stirnseite eines jeden Betätigungsarmes 27 ein Keilstück 30 aus.The end faces of the actuating arms 27 have two obliquely arranged on the edge 28, the lifting surfaces form. Between the two lifting surfaces 28, the end face of each actuating arm 27 forms a wedge 30 from.

An den freien Enden der Federzungen 8 befinden sich Bogenstücke. Diese Bogenstücke bilden die Gewindeeingriffsvorsprünge 5 aus. Die Gewindeeingriffsvorsprünge 5 verlaufen auf der Konturlinie eines Gewindes. Es handelt sich hier um ein Außengewinde. Die Bogenstücke überragen die Betätigungsarme 27 in Umfangsrichtung und bilden jeweils Überstände aus. Die Innenwandungen der Überstände 29 sind mit Schrägen 45 ausgebildet. Diese Schrägen korrespondieren zu den Hubflächen 28 der Betätigungsarme 27. Vor Kopf der Federzungen 8, unmittelbar angrenzend an die Gewindeeingriffsvorsprünge 5 befindet sich ein Stirnkragen 34 des Kontaktträgers 3.There are elbows at the free ends of the spring tongues 8. These elbows form the threaded engagement projections 5. The thread engagement projections 5 run on the contour line of a thread. It deals here around an external thread. The bow pieces project beyond the actuating arms 27 in the circumferential direction and form protrusions in each case. The inner walls of the projections 29 are formed with bevels 45. These bevels correspond to the lifting surfaces 28 of the actuating arms 27. In front of the head of the spring tongues 8, immediately adjacent to the threaded engagement projections 5, there is a front collar 34 of the contact carrier 3.

Ein rückwärtiges Ende des Kontaktträgers 3 ist mit einer Kunststoffummantelung 20 formschlüssig und dicht verbunden. Die Kunststoffummantelung 20 überfängt den Kontaktbereich der Adern des Kabels 19 mit den Kontaktelementen 18, die sich im Kontaktträger 3 befinden.A rear end of the contact carrier 3 is positively and tightly connected to a plastic casing 20. The plastic sheath 20 traps the contact area of the wires of the cable 19 with the contact elements 18, which are located in the contact carrier 3.

Bei der in den Figuren 5 und 6 dargestellten Freigabestellung liegen die Federzungen 8 und die von ihnen getragenen Gewindeeingriffvorsprünge 5 auf der Außenwandung des zylindrischen Kontaktträgers 3 auf und nehmen somit eine radial rückverlagerte Stellung ein. In dieser Betriebsstellung kann ein Sockel 35 eines Gegensteckerelementes in die Einstecköffnung 33 des Steckerelementes 1 eingesteckt werden. Ein den Sockel 35 mit Abstand umgebendes Innengewindeteil mit einem Gegengewinde 6 verlagert sich dabei über die Gewindevorsprünge 5. Der Abstand zwischen Gegengewinde und Sockelaußenwandung hat eine entsprechende Größe. Diese axiale Zusammensteckbewegung ist beendet, wenn die von dem Stirnkragen 34 gebildete Stirnfläche gegen einen Dichtring 23 des Gegensteckerelementes 2 tritt. Dann kann die Betätigungshülse 4 in Achsrichtung auf das Gegensteckerelement verlagert werden. Dabei treten die angeschrägten Hubflächen 28 unter die Überstandsabschnitte 29 der Bogenstücke, die die Gewindeeingriffsvorsprünge 5 ausbilden. Die Überstandsabschnitte 29 bilden hierfür Schrägen 45 an, an denen die Hubflächen 28 gleiten können. Im Zuge der Axialverlagerung der Betätigungshülse 4 verlässt die Rastnase 13 die ihr zugeordnete Rastaussparung 12. Das Keilstück 30 tritt dabei zwischen die beiden Umfangsstirnflächen zweier benachbarter Bogenstücke, um sie umfangsvergrößernd auseinander zu treiben. Die Schrägflanke 28 des Betätigungsarmes 27 unterläuft dabei die Schrägflanke 45 des Überstandes 29 des Bogenstücks. Dies führt zu einer Radialverlagerung des Bogenstücks. Einhergehend mit dieser Radialverlagerung der federelastischen Federzungen 8 in Radialauswärtsrichtung treten die Gewindeeingriffsvorsprünge 5 in die entsprechenden Gewindegänge des Gegengewindes 6 ein, bis die Betätigungshülse 4 ihre in den Figuren 7 und 8 dargestellte Endstellung erreicht hat, in welcher die Rastnase 13 in die ihr zugeordnete Rastaussparung 12 eingetreten ist.In the in the FIGS. 5 and 6 illustrated release position are the spring tongues 8 and the threaded engagement projections 5 carried by them on the outer wall of the cylindrical contact carrier 3 and thus assume a radially rearward position. In this operating position, a socket 35 of a mating connector element can be inserted into the insertion opening 33 of the plug element 1. A socket surrounding the socket 35 at a distance with an internally threaded part with a mating thread 6 displaced by the thread projections 5. The distance between mating thread and Sockelaußenwandung has a corresponding size. This axial mating movement is completed when the end face formed by the end collar 34 passes against a sealing ring 23 of the mating connector element 2. Then, the actuating sleeve 4 can be displaced in the axial direction on the mating connector element. In this case, the tapered lifting surfaces 28 come under the projecting portions 29 of the elbows, which form the threaded engagement projections 5. The projecting portions 29 form for this purpose slopes 45, on which the lifting surfaces 28 can slide. In the course of the axial displacement of the actuating sleeve 4, the locking lug 13 leaves the associated locking recess 12. The wedge piece 30 occurs between the two peripheral end faces of two adjacent curved pieces to drive them circumferentially enlarging apart. The oblique edge 28 of the actuating arm 27 thereby undermines the inclined edge 45 of the supernatant 29 of the elbow. This leads to a radial displacement of the elbow. Along with this radial displacement of the resilient spring tongues 8 in Radialauswärtsrichtung the threaded engagement projections 5 enter the corresponding threads of the counter-thread 6 until the actuating sleeve 4 their in the FIGS. 7 and 8 has reached the end position in which the latching lug 13 has entered into its associated locking recess 12.

In dieser Position kann die Betätigungshülse 4 gedreht werden. Sie wirkt dann wie eine Gewindehülse und erzeugt eine Schraubkraft, die eine Kompression des Dichtringes 23 zur Folge hat. Das Trennen von Steckerelement 1 und Gegensteckerelement 2 erfolgt durch ledigliches axiales Rückverlagern der Betätigungshülse aus ihrer Verriegelungsstellung in ihre Freigabestellung. Im Zuge dieser Rückverlagerung treten die Gewindeeingriffsvorsprünge 5 aus den Gewindegängen des Gegengewindes 6 heraus. Dies erfolgt zufolge der Rückstellfähigkeit der Federzungen 8. In der Endphase dieser axialen Rückverlagerung der Betätigungshülse 4 verrastet letztere in Bezug auf das Gewindeeingriffsteil 7. Zufolge des fehlenden formschlüssigen Gewindeeingriffs können die Steckerteile 1, 2 voneinander getrennt werden.In this position, the actuating sleeve 4 can be rotated. It then acts like a threaded sleeve and generates a screwing force, which has a compression of the sealing ring 23 result. The separation of plug element 1 and mating connector element 2 is carried out by merely axial relocation of the actuating sleeve from its locking position into its release position. In the course of this return displacement, the threaded engagement projections 5 come out of the threads of the counter thread 6. This is due to the resilience of the spring tongues 8. In the final phase of this axial return displacement of the actuating sleeve 4, the latter latched with respect to the threaded engagement portion 7. Due to the lack of positive threaded engagement, the connector parts 1, 2 are separated.
