Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Steckverbinderanordnung, die einen Steckverbinder und ein daran angeschlossenes Koaxialkabel umfasst, gemäß dem Oberbegriff von Patentanspruch 1. Dabei wird zunächst (a) eine Stützhülse auf ein Ende eines Koaxialkabels aufgeschoben, (b) dann ein Außenleiter des Koaxialkabels um die Stützhülse herum zurückgeschlagen, und (c) schließlich das Ende des Koaxialkabels mit der Stützhülse in einen Hülsenabschnitt eines Außenleitergehäuses des Steckverbinders eingeführt.The invention relates to a method for producing a connector assembly comprising a connector and a coaxial cable connected thereto, according to the preamble of claim 1. In this case, first (a) a support sleeve is pushed onto one end of a coaxial cable, (b) then an outer conductor of the coaxial cable (b) Finally, the end of the coaxial cable with the support sleeve inserted into a sleeve portion of an outer conductor housing of the connector.

Herkömmliche Steckverbinder haben ein steckseitiges Ende zum Verbinden des Steckverbinders mit einem Gegensteckverbinder und ein kabelseitiges Ende, an dem das Kabel (vorzugsweise unlösbar durch Löten oder Crimpen) befestigt ist. Dabei ist zumindest ein Innenleiter des Kabels elektrisch mit einem Innenleiterkontakt wie etwa einem Kontaktstift oder einer Kontaktbuchse verbunden, der in einem Isolierteil des Steckverbinders gehalten ist. Der Außenleiter des Kabels, bspw. ein Folienschirm oder ein Drahtgeflecht, ist elektrisch mit einem den Innenleiterkontakt umlaufenden Außenleitergehäuse des Steckverbinders verbunden, so dass vorzugsweise von dem Koaxialkabel bis hin zu dem steckseitigen Ende des Steckverbinders eine durchgehende Schirmung gebildet ist.Conventional connectors have a male end for connecting the connector to a mating connector and a cable end to which the cable is attached (preferably non-releasably by soldering or crimping). In this case, at least one inner conductor of the cable is electrically connected to an inner conductor contact, such as a contact pin or a contact socket, which is held in an insulating part of the connector. The outer conductor of the cable, for example a foil screen or a wire mesh, is electrically connected to a peripheral conductor housing of the connector so that preferably a continuous shielding is formed from the coaxial cable to the plug-side end of the connector.

Es ist bekannt, zum Herstellen einer Steckverbinderanordnung das aus einem elektrisch leitenden Material bestehende und zumindest abschnittweise hülsenförmige Außenleitergehäuse des Steckverbinders mit dem Außenleiter des Kabels zu vercrimpen bzw. zu verpressen. Dazu wird bei der Herstellung der Steckverbinderanordnung das Kabel an seinem vorderem Ende abisoliert bzw. der vercrimpen bzw. zu verpressen. Dazu wird bei der Herstellung der Steckverbinderanordnung das Kabel an seinem vorderem Ende abisoliert bzw. der Kabelmantel abschnittsweise entfernt, so dass der Außenleiter freigelegt ist. Anschließend wird das den Außenleiter umlaufende Außenleitergehäuse mit dem Kabel-Außenleiter verpresst, wobei eine Crimphülse zum Bereitstellen einer Stützwirkung vorgesehen sein kann.It is known to crimp or press the existing of an electrically conductive material and at least partially sleeve-shaped outer conductor housing of the connector with the outer conductor of the cable for producing a connector assembly. For this purpose, in the manufacture of the connector assembly, the cable is stripped at its front end or the crimp or crimp. For this purpose, in the manufacture of the connector assembly, the cable is stripped at its front end or the cable sheath removed in sections, so that the outer conductor is exposed. Subsequently, the outer conductor housing surrounding the outer conductor is pressed with the cable outer conductor, wherein a crimping sleeve can be provided for providing a supporting action.

Die Druckschrift GB 2 139 018 A beschreibt ein Verfahren zum Herstellen einer Verbindung zwischen einem Koaxialkabel und einem inneren Schaltenteil mittels eines äußeren Schalenteils. Die Druckschrift DE 10 2004 007 357 A1 beschreibt ein Verfahren zum Montieren eines HF-Steckkontakts am Ende eines Koaxialkabels. Die Druckschrift WO 2009/119738 A1 beschreibt ein Verfahren zum Montieren eines Steckers an einem Kabel mittels Klemmring. Die Druckschrift US 4 795 352 A beschreibt ein Verfahren zum Herstellen einer Verbindung zwischen einem Koaxialkabel und einem Steckverbinder, die ohne Vercrimpung auskommen soll.The publication GB 2 139 018 A describes a method for establishing a connection between a coaxial cable and an inner switching part by means of an outer shell part. The publication DE 10 2004 007 357 A1 describes a method of mounting an RF plug at the end of a coaxial cable. The publication WO 2009/119738 A1 describes a method for mounting a plug to a cable by means of a clamping ring. The publication US 4 795 352 A describes a method for establishing a connection between a coaxial cable and a connector, which is to make do without crimping.

Es hat sich allerdings herausgestellt, dass eine auf die beschriebene herkömmliche Art hergestellte Steckverbinderanordnung im Bereich der Verbindung zwischen dem Steckverbinder und dem Kabel regelmäßig nicht optimal elektrisch angepasst ist. Insbesondere kann es im Verbindungsbereich zu ungewollten Abweichungen von dem vorgesehenen Wellenwiderstand wie etwa zu einem unerwünschten Impedanzanstieg kommen.However, it has been found that a connector assembly prepared in the conventional manner described in the region of the connection between the connector and the cable is not regularly optimally adapted electrically. In particular, unintentional deviations from the characteristic impedance provided, such as an undesired increase in impedance, may occur in the connection region.

Um dieses Problem zu lösen, wird in der Druckschrift DE 20 2015 000 750 U vorgeschlagen, ein zusätzliches Hülsenteil im Inneren eines Hülsenabschnitts des Steckverbinders vorzusehen, das sich an ein axiales Ende des Außenleiters anschließt. In der Druckschrift DE 20 2015 000 751 U wird vorgeschlagen, den elektrisch nicht optimal angepassten Bereich zwischen dem axialen Ende des Außenleiters und dem Steckverbinder mit einer radialen Verengung in Form einer zusätzlichen Crimpstelle zu versehen.To solve this problem, is in the document DE 20 2015 000 750 U proposed to provide an additional sleeve member inside a sleeve portion of the connector, which adjoins an axial end of the outer conductor. In the publication DE 20 2015 000 751 U It is proposed to provide the electrically not optimally adapted region between the axial end of the outer conductor and the connector with a radial constriction in the form of an additional crimping.

Durch diese Maßnahmen kann der Wellenwiderstand in dem Verbindungsbereich zwar verbessert werden, allerdings wird dadurch der Aufwand zum Herstellen der Steckverbinderanordnung erhöht.Although the characteristic impedance in the connection region can be improved by these measures, the effort for producing the connector arrangement is thereby increased.

In Anbetracht der beschriebenen Probleme ist es die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Herstellen einer Steckverbinderanordnung dahingehend zu verbessern, dass eine stabil und zugfest eingerichtete Verbindung zwischen dem Steckverbinder und dem Koaxialkabel unter einem möglichst geringen Herstellungsaufwand bereitgestellt werden kann, die ferner möglichst über ihre gesamte Erstreckung in Kabellängsrichtung optimal elektrisch angepasst ist.In view of the described problems, it is the object of the present invention to improve a method for producing a connector assembly in that a stable and zugfest established connection between the connector and the coaxial cable can be provided with the least possible manufacturing effort, as far as possible over their entire extension in the cable longitudinal direction is optimally adjusted electrically.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den in Patentanspruch 1 gekennzeichneten Verfahrensschritten gelöst. Vorteilhafte zusätzliche Verfahrensschritte sind in den abhängigen Ansprüchen beschrieben. Bei dem erfindungsgemäßen Verfahren wird (d) die Stützhülse im Anschluss an Schritt (c) relativ zu dem Koaxialkabel und dem Steckverbinder bis zu einem axialen Anschlag in den Hülsenabschnitt hineinbewegt.This object is achieved by a method with the method steps indicated in claim 1. Advantageous additional method steps are described in the dependent claims. In the method according to the invention, (d) the support sleeve is moved into the sleeve section as far as an axial stop after step (c) relative to the coaxial cable and the connector.

Mit anderen Worten wird in Schritt (c) zunächst das Kabelende zusammen mit der darauf angeordneten Stützhülse bis zu einem (ersten) axialen Anschlag in den Hülsenabschnitt des Steckverbinders eingeführt, und anschließend wird in Schritt (d) die Stützhülse alleine weiter bis zu einem (zweiten) axialen Anschlag in den Hülsenabschnitt hineinbewegt, ohne dass das Koaxialkabel mitbewegt wird, so dass in Schritt (d) die Stützhülse relativ zu dem Kabel bewegt wird.In other words, in step (c), first the cable end is inserted together with the support sleeve disposed thereon up to a (first) axial stop in the sleeve portion of the connector, and then in step (d) the support sleeve alone is further extended to a (second ) axial stop is moved into the sleeve portion without the coaxial cable is moved, so that in step (d) the support sleeve is moved relative to the cable.

Der um die Stützhülse herum zurückgeschlagene Außenleiter des Kabels, der vorzugsweise in Form eines zurückfaltbaren Folienschirms oder Drahtgeflechts ausgebildet ist, kann bei Schritt (d) entweder abschnittsweise elastisch in axialer Richtung gedehnt werden, oder der umgeschlagene Teil des Außenleiters gleitet um das vordere Ende der Stützhülse herum zurück in Anlage an das Koaxialkabel, unter Verkleinerung des außen an der Stützhülse anliegenden Umschlagfalzes des Kabel-Außenleiters.The outer conductor of the cable folded back around the support sleeve, which is preferably designed in the form of a foldable foil screen or wire mesh, can either be elastically stretched in sections in step (d) in the axial direction, or the folded part of the outer conductor slides around the front end of the support sleeve around back in contact with the coaxial cable, while reducing the voltage applied to the outside of the support sleeve Umschlagfalzes the outer cable conductor.

Ein Hineinbewegen der Stützhülse in den Hülsenabschnitt in Schritt (d) kann dadurch vereinfacht werden, dass der Außendurchmesser des um die Stützhülse zurückgeschlagenen Kabel-Außenleiters etwas kleiner ist als der Innendurchmesser des Hülsenabschnitts.Moving the support sleeve into the sleeve section in step (d) can be simplified in that the outside diameter of the cable outer conductor folded back around the support sleeve is slightly smaller than the inside diameter of the sleeve section.

Der Hülsenabschnitt des Steckverbinders ist vorzugsweise mit einem Außenleitergehäuse des Steckverbinders verbunden oder integral bzw. einteilig damit gebildet. Mit anderen Worten weist das Außenleitergehäuse des Steckverbinders am kabelseitigen Ende den rohrförmig vorstehenden Hülsenabschnitt zum Einführen des Koaxialkabels auf, wobei vorzugsweise das Außenleitergehäuse zusammen mit dem Hülsenabschnitt aus einem leitenden Material wie etwa einem Metall besteht. Der den Kabel-Außenleiter umlaufende und ihn elektrisch kontaktierende Hülsenabschnitt des Außenleitergehäuses setzt in diesem Fall die Schirmung in Richtung auf das steckseitige Ende des Steckverbinders fort.The sleeve portion of the connector is preferably connected to an outer conductor housing of the connector or integrally or integrally formed therewith. In other words, the outer conductor housing of the connector at the cable end has the tubular protruding sleeve portion for insertion of the coaxial cable, wherein preferably the outer conductor housing together with the sleeve portion made of a conductive material such as a metal. In this case, the sleeve section of the outer conductor housing which circumscribes the cable outer conductor and makes electrical contact with it continues the shielding in the direction of the plug-side end of the connector.

Die Erfindung geht auf die Erkenntnis zurück, dass nach dem Einführen des Koaxialkabelendes in den Hülsenabschnitt des Steckverbinders in Schritt (c) das vordere axiale Ende des Kabel-Außenleiters noch nicht notwendigerweise an dem Außenleitergehäuse des Steckverbinders anliegt, so dass an dieser Stelle ein Sprung im Abstand zwischen dem Innenleiter und dem die Schirmung des Innenleiters bildenden Hülsenabschnitt auftreten kann. Zum Erhalt einer in Kabellängsrichtung gleichbleibenden Impedanz bei unveränderter Kabelgeometrie ist allerdings ein im Wesentlichen gleichbleibender Abstand zwischen dem Innenleiter und dem Außenleiter erforderlich. So führt eine Vergrößerung des Abstands zwischen Innenleiter und Außenleiter regelmäßig zu einem induktiven Bereich bzw. zu einem ungewollten Impedanzanstieg. Eine unerwünschte sprunghafte Änderung des Abstands zwischen dem Innenleiter und dessen Schirmung liegt bei herkömmlichen Steckverbinderanordnungen regelmäßig an dem vorderen axialen Ende des zurückgefalteten Kabel-Außenleiters vor. Erfindungsgemäß wird dagegen durch das weitere Hineinbewegen des Stützhülse in den Hülsenabschnitt in Schritt (d) bis zu einem (zweiten) Anschlag auf einfache Weise sichergestellt, dass sich die Schirmung auch im Bereich des vorderen axialen Endes des Außenleiters mit gleichbleibender Entfernung zum Innenleiter fortsetzt, so dass kein Impedanzsprung in diesem Bereich auftritt.The invention is based on the finding that after insertion of the coaxial cable end in the sleeve portion of the connector in step (c), the front axial end of the cable outer conductor is not necessarily applied to the outer conductor housing of the connector, so that at this point a jump in Distance between the inner conductor and the shielding of the inner conductor forming sleeve portion may occur. In order to obtain a constant cable length in the same impedance with unchanged cable geometry, however, a substantially constant distance between the inner conductor and the outer conductor is required. Increasing the distance between the inner conductor and outer conductor regularly leads to an inductive region or to an unwanted increase in impedance. An undesirable step change in the distance between the inner conductor and its shield is in conventional connector assemblies at the front axial end of the folded-back outer cable conductor regularly. According to the invention, however, by further advancing the support sleeve in the sleeve portion in step (d) up to a (second) stop easily ensures that the shield also continues in the region of the front axial end of the outer conductor with a constant distance to the inner conductor, so that no impedance jump occurs in this area.

Der Hülsenabschnitt wird anschließend mit dem die Stützhülse tragenden Ende des Koaxialkabels vercrimpt. Mit anderen Worten wird durch eine radiale Presskraft von außen auf den Hülsenabschnitt der um die Stützhülse herum umgeschlagene Außenleiter mit dem Hülsenabschnitt verpresst, so dass eine zugfeste und stabile Verbindung zwischen dem Koaxialkabel und dem Außenleitergehäuse des Steckverbinders hergestellt wird. Im Hinblick auf weitere Details dieser Crimpverbindung wird auf die Druckschrift DE 20 2015 000 751 U verwiesen, deren Inhalt durch Verweis vollumfänglich in die vorliegende Beschreibung aufgenommen wird.The sleeve portion is then crimped with the support sleeve bearing end of the coaxial cable. In other words, by a radial pressing force from the outside of the sleeve portion of the folded around the support sleeve outer conductor is pressed with the sleeve portion, so that a high-tensile and stable connection between the coaxial cable and the outer conductor housing of the connector is produced. With regard to further details of this crimp connection will be to the document DE 20 2015 000 751 U whose content is incorporated by reference in its entirety into the present description.

Vorteilhafterweise wird in Schritt (c) das Ende des Koaxialkabels so weit in den Hülsenabschnitt des Steckverbinders eingeführt, bis zumindest ein mit einem Innenleiter des Koaxialkabels elektrisch verbundener Innenleiterkontakt in ein Isolierteil des Steckverbinders einrastet. Das Einrasten des an dem vorderen Kabelende angebrachten Innenleiterkontakts in das Isolierteil des Steckverbinders kann zu dem oben erwähnten (ersten) axialen Anschlag führen, der ein weiteres Einführen des Koaxialkabels in den Hülsenabschnitt verhindert. Dagegen ist ein weiteres Einführen der Stützhülse in den Hülsenabschnitt relativ zu dem Innenleiter in Schritt (d) bis zu einem (zweiten) axialen Anschlag noch möglich. Gemäß dem erfindungsgemäßen Verfahren kann folglich eine korrekte Positionierung sowohl der Innenleiter als auch der Außenleiter zwischen Kabel und Steckverbinder sichergestellt werden.Advantageously, in step (c), the end of the coaxial cable is inserted so far into the sleeve portion of the connector until at least one of an inner conductor of the coaxial cable electrically connected inner conductor contact engages in an insulating part of the connector. The engagement of the inner conductor contact attached to the front end of the cable into the insulator portion of the connector may result in the aforementioned (first) axial abutment which prevents further insertion of the coaxial cable into the sleeve portion. In contrast, further insertion of the support sleeve in the sleeve portion relative to the inner conductor in step (d) to a (second) axial stop is still possible. Consequently, according to the method of the invention, correct positioning of both the inner conductor and the outer conductor between the cable and the connector can be ensured.

Alternativ befindet sich der Innenleiterkontakt im Anschluss an Schritt (c) noch in einer Vorfügeposition und wird erst anschließend in eine axiale Endlage im Inneren des Isolierteil des Steckverbinders gebracht.Alternatively, the inner conductor contact is still in a Vorfügeposition following step (c) and is only then brought into an axial end position in the interior of the insulating part of the connector.

Im Hinblick auf eine Optimierung des Wellenwiderstands am vorderen Ende des Kabel-Außenleiters hat es sich als zweckmäßig erwiesen, dass in Schritt (d) die Stützhülse so weit relativ zu dem Koaxialkabel und dem Steckverbinder bewegt wird, bis der die axiale Front der Stützhülse umlaufende Abschnitt des Kabel-Außenleiters an dem in Form einer Stufe ausgebildeten Anschlag im Inneren des Hülsenabschnitts anschlägt. Im Hinblick auf eine Weiterführung des Abstands zwischen Außenleiter und Innenleiter unter gleichbleibendem Abstand ist es dabei vorteilhaft, dass der Innendurchmesser des Steckverbinders ab der den axialen Anschlag des Kabel-Außenleiters ausbildenden Stufe im Wesentlichen dem Durchmesser des Außenleiters des Koaxialkabels beträgt.In view of optimizing the characteristic impedance at the front end of the cable outer conductor, it has proven to be expedient that in step (d) the support sleeve is moved so far relative to the coaxial cable and the connector until the axial Front of the support sleeve circumferential portion of the outer cable conductor abuts the formed in the form of a step stop inside the sleeve portion. With regard to a continuation of the distance between the outer conductor and inner conductor at a constant distance, it is advantageous that the inner diameter of the connector from the axial stop of the cable outer conductor forming step is substantially the diameter of the outer conductor of the coaxial cable.

Das Hineinschieben der Stützhülse in den Hülsenabschnitt bis zu dem axialen Anschlag kann dadurch vereinfacht werden, dass die Stützhülse einen radial vorstehenden Abschnitt wie etwa einen umlaufenden Vorsprung oder Bund aufweist, an dem die Stützhülse zum Bewegen in Schritt (d) manuell oder mit einem Werkzeug ergriffen wird. Der radial vorstehende Abschnitt bildet vorzugsweise das kabelseitige Ende der Stützhülse und/oder umläuft das Koaxialkabel in Form eines Ringbunds. Der Außendurchmesser der Stützhülse im Bereich des Vorsprungs ist vorzugsweise größer als der Innendurchmesser des Hülsenabschnitts, so dass der Vorsprung nicht in den Hülsenabschnitt hinein verschiebbar ist.The insertion of the support sleeve into the sleeve portion up to the axial stop can be facilitated by the support sleeve having a radially projecting portion such as a circumferential projection or collar on which the support sleeve for moving in step (d) gripped manually or with a tool becomes. The radially projecting portion preferably forms the cable end of the support sleeve and / or rotates the coaxial cable in the form of a collar. The outer diameter of the support sleeve in the region of the projection is preferably larger than the inner diameter of the sleeve portion, so that the projection is not slidable into the sleeve portion.

Vorzugsweise wird die Stützhülse in Schritt (d) so weit in den Hülsenabschnitt hineinbewegt, bis der radial vorstehende Abschnitt an dem kabelseitigen Ende des Hülsenabschnitts anschlägt, wobei die axiale Abmessung der Stützhülse derart eingerichtet sein kann, dass gleichzeitig das vordere Ende des Kabel-Außenleiters an dem axialen Anschlag im Inneren des Hülsenabschnitts anschlägt.Preferably, the support sleeve in step (d) is moved so far into the sleeve portion until the radially projecting portion abuts the cable end of the sleeve portion, wherein the axial dimension of the support sleeve can be configured such that at the same time the front end of the cable outer conductor strikes the axial stop in the interior of the sleeve portion.

Vorteilhafterweise wird vor dem Aufschieben der Stützhülse auf das Ende des Koaxialkabels die Kabelisolierung des Koaxialkabels abisoliert, um den Außenleiter freizulegen, und in Schritt (a) wird die Stützhülse so weit außen auf den Außenleiter aufgeschoben, bis die Stützhülse an der Kabelisolierung anschlägt.Advantageously, prior to sliding the support sleeve onto the end of the coaxial cable, the cable insulation of the coaxial cable is stripped to expose the outer conductor, and in step (a) the support sleeve is slid so far outward on the outer conductor until the support sleeve abuts the cable insulation.

Die Stützhülse und/oder der Hülsenabschnitt des Steckverbinders sind vorzugsweise im Wesentlichen rotationssymmetrisch und insbesondere jeweils etwa zylindermantelförmig bzw. rohrförmig ausgebildetThe support sleeve and / or the sleeve portion of the connector are preferably substantially rotationally symmetrical and in particular each approximately cylinder jacket-shaped or tubular

Gemäß einem weiteren Gesichtspunkt betrifft die vorliegende Erfindung eine gemäß dem erfindungsgemäßen Verfahren hergestellte Steckverbinderanordnung. Eine Steckverbinderanordnung besteht aus einem Steckverbinder mit einem Außenleitergehäuse, das kabelseitig einen rohrförmigen Hülsenabschnitt aufweist, und einem daran angeschlossenen Koaxialkabel. Ein vorderes Ende des Koaxialkabels mit einer darauf aufgeschobenen Stützhülse, um die herum ein Außenleiter des Koaxialkabels zurückgeschlagen ist, ist so weit in den Hülsenabschnitt des Steckverbinders vorgeschoben, dass die axiale Front des umgeschlagenen Außenleiters an einem Anschlag im Inneren des Hülsenabschnitts anschlägt. Der Anschlag kann als stufenförmiger Absatz im Inneren des Hülsenabschnitts ausgebildet sein. Der Innendurchmesser des Steckverbinders im Bereich des Absatzes sollte im Hinblick auf eine optimale elektrische Anpassung an den Durchmesser des Außenleiters des Koaxialkabels angepasst sein.In another aspect, the present invention relates to a connector assembly made in accordance with the method of the invention. A connector assembly consists of a connector with an outer conductor housing, the cable side has a tubular sleeve portion, and a coaxial cable connected thereto. A front end of the coaxial cable with a support sleeve slid thereabout, around which an outer conductor of the coaxial cable is folded, has advanced so far into the sleeve portion of the connector that the axial front of the folded outer conductor abuts against a stop in the interior of the sleeve portion. The stop may be formed as a stepped shoulder in the interior of the sleeve portion. The inner diameter of the connector in the area of the shoulder should be adjusted for optimum electrical adaptation to the diameter of the outer conductor of the coaxial cable.

Im Hinblick auf die weiteren bevorzugten Merkmale der erfindungsgemäßen Steckverbinderanordnung wird auf die obigen Ausführungen verwiesen.With regard to the further preferred features of the connector assembly according to the invention, reference is made to the above statements.

Vorzugsweise weist die Stützhülse kabelseitig einen radial vorstehenden Abschnitt in Form eines Vorsprungs wie etwa einen Bund, insbesondere einen das Koaxialkabel umlaufenden Ringbund auf. Der Außendurchmesser der Stützhülse an dem radial vorstehenden Abschnitt ist vorzugsweise größer als der Innendurchmesser des Hülsenabschnitts des Steckverbinders, und ist besonders bevorzugt etwa genauso groß wie der Außendurchmesser des Hülsenabschnitts, so dass der radial vorstehende Abschnitt im Wesentlichen mit dem Hülsenabschnitt fluchtet.Preferably, the support sleeve on the cable side has a radially projecting portion in the form of a projection, such as a collar, in particular an annular collar surrounding the coaxial cable. The outer diameter of the support sleeve at the radially protruding portion is preferably larger than the inner diameter of the sleeve portion of the connector, and more preferably is about the same size as the outer diameter of the sleeve portion, so that the radially protruding portion is substantially flush with the sleeve portion.

Bei einer besonders bevorzugten Ausführungsform umfasst die Steckverbinderanordnung zumindest einen in ein Isolierteil des Steckverbinders eingeclipsten Innenleiterkontakt, der mit dem Innenleiter des Koaxialkabels elektrisch verbunden ist, und der zum Übertragen von elektrischen Strömen und/oder Signalen vorgesehen ist.In a particularly preferred embodiment, the plug connector arrangement comprises at least one inner conductor contact which is clipped into an insulating part of the plug connector and which is electrically connected to the inner conductor of the coaxial cable and which is provided for transmitting electrical currents and / or signals.

In der nun folgenden Beschreibung wird die Erfindung unter Bezugnahme auf die beigefügten Zeichnungen im Detail beschrieben. Darin zeigen:

In the following description, the invention will be described in detail with reference to the accompanying drawings. Show:
Fig. 1a to 1e
five steps in the manufacture of a connector assembly according to the manufacturing method of the invention, and
Fig. 2
an exploded view of a connector assembly according to the invention.

Fig. 1a zeigt ein an einem vorderen Ende abisoliertes Koaxialkabel 20, das einen Innenleiter, einen Außenleiter 22 in Form eines Drahtgeflechts, ein zwischen Innenleiter und Außenleiter 22 angeordnetes Dielektrikum und eine Kabelisolierung 24 als Schutzmantel aufweist. Auf das Ende des Koaxialkabels, und zwar außen auf den Außenleiter 22, ist eine Stützhülse 30 aus einem leitenden Material wie etwa Metall aufgeschoben. Fig. 1a shows a coaxial cable 20 insulated at a front end, which has an inner conductor, an outer conductor 22 in the form of a wire mesh, a dielectric disposed between inner conductor and outer conductor 22, and a cable insulation 24 as a protective jacket. On the end of the coaxial cable, outside of the outer conductor 22, a support sleeve 30 made of a conductive material such as metal is pushed.

Die Stützhülse 30 ist rohrförmig ausgebildet (siehe auch Fig. 2) und ihr Innendurchmesser ist an den Außendurchmesser des Kabel-Außenleiters 22 angepasst. An ihrem kabelseitigen Ende weist die Stützhülse 30 einen radial vorstehenden Abschnitt 32 in Form eines das Koaxialkabel ringförmig umlaufenden Vorsprungs ("Ringbund") auf.The support sleeve 30 is tubular (see also Fig. 2 ) and its inner diameter is adapted to the outer diameter of the cable outer conductor 22. At its cable end, the support sleeve 30 has a radially projecting portion 32 in the form of a coaxial cable annular circumferential projection ("ring collar").

Nach dem Aufschieben der Stützhülse 30, bis diese an der Kabelisolierung 24 anschlägt, wird ein Teil des als Drahtgeflecht o.dgl. ausgebildeten Kabel-Außenleiters 22 um die Stützhülse 30 herum zurückgeschlagen. Der zurückgeschlagene Umschlagfalz des Kabel-Außenleiters 22 ist in Fig. 1b dunkel dargestellt. Ferner wird ein Innenleiterkontakt 40 an den Innenleiter des Kabels 20 anmontiert, der dann das vordere Ende der in Fig. 1b dargestellten Kabel-Baugruppe bildet.After pushing the support sleeve 30 until it abuts the cable insulation 24, a part of the wire mesh or the like. trained cable outer conductor 22 is beaten back around the support sleeve 30 around. The folded-back fold of the cable outer conductor 22 is in Fig. 1b shown darkly. Further, an inner conductor contact 40 is mounted on the inner conductor of the cable 20, which then the front end of the in Fig. 1b formed cable assembly forms.

Nun wird das vordere Ende des Koaxialkabels 20 mit dem Steckverbinder 10 verbunden. Der Steckverbinder 10 umfasst ein (leitendes) Außenleitergehäuse mit einem kabelseitig vorstehenden rohrförmigen Hülsenabschnitt 12 und ein darin aufgenommenes Isolierteil 42 mit einem Innenleiterkanal zum Einclipsen des Innenleiterkontakts 40. Der Innendurchmesser des Hülsenabschnitts 12 ist etwas größer als der Durchmesser des um die Stützhülse 30 umgeschlagenen Kabel-Außenleiters 22, so dass dieser problemlos in den Hülsenabschnitt 12 des Außenleitergehäuses einführbar ist (siehe Fig. 1c).Now, the front end of the coaxial cable 20 is connected to the connector 10. The connector 10 includes a (conductive) outer conductor housing having a tube-side projecting tubular sleeve portion 12 and a therein The inner diameter of the sleeve portion 12 is slightly larger than the diameter of the folded about the support sleeve 30 outer cable conductor 22 so that it can be easily inserted into the sleeve portion 12 of the outer conductor housing (see Fig. 1c ).

Die Kabel-Baugruppe wird so weit in den Hülsenabschnitt 12 eingeführt, bis der Innenleiterkontakt 40 in dem Isolierteil 42 des Steckverbinders eingeclipst ist oder auf andere Weise an dem Steckverbinder 10 anschlägt (erster Anschlag). Alternativ ist der Innenleiterkontakt 40 in einer Vorfügeposition angeordnet.The cable assembly is inserted so far into the sleeve portion 12 until the inner conductor contact 40 is clipped in the insulating part 42 of the connector or otherwise abuts the connector 10 (first stop). Alternatively, the inner conductor contact 40 is arranged in a Vorfügeposition.

Nun wird die Stützhülse 30 am radial vorstehenden Abschnitt 32 ergriffen und noch weiter in den Hülsenabschnitt 12 hineinbewegt (siehe Bezugszeichen X), bis die vordere Front des Kabelschirmgeflechts 22 an einem stufenförmigen Absatz 14 im Inneren des Hülsenabschnitts 12 anschlägt, so dass die Schirmung mit gleichbleibenden Abstand in Richtung auf das steckseitige Ende des Steckverbinders fortgeführt werden kann. Wichtig ist, dass am vorderen axialen Ende des Außenleiters 22 kein Freiraum oder Sprung vorhanden ist, was besonders deutlich in Fig. 1d dargestellt ist.Now, the support sleeve 30 is gripped on the radially projecting portion 32 and further moved into the sleeve portion 12 (see reference numeral X) until the front of the cable shield braid 22 abuts a stepped shoulder 14 inside the sleeve portion 12, so that the shield with constant Distance in the direction of the plug-side end of the connector can be continued. It is important that at the front axial end of the outer conductor 22 no clearance or crack is present, which is particularly evident in Fig. 1d is shown.

Schließlich wird der Hülsenabschnitt 12 mit dem Kabel-Außenleiter 22 vercrimpt (siehe Fig. 1e).Finally, the sleeve portion 12 is crimped with the cable outer conductor 22 (see Fig. 1e ).

Fig. 1e zeigt eine gemäß dem erfindungsgemäßen Verfahren hergestellte Steckverbinderanordnung 100. Fig. 1e shows a connector assembly 100 produced according to the method of the invention.

Fig. 2 zeigt die Einzelteile, aus denen eine erfindungsgemäße Steckverbinderanordnung 100 hergestellt wird, nämlich den aus Isolierteil 42 und Außenleitergehäuse mit Hülsenabschnitt 12 bestehenden Steckverbinder, die Stützhülse 30, den Innenleiterkontakt 40 und das Koaxialkabel 20, in einer Explosionsdarstellung. Fig. 2 shows the items from which a connector assembly 100 according to the invention is made, namely consisting of insulating 42 and outer conductor housing with sleeve portion 12 connector, the support sleeve 30, the inner conductor contact 40 and the coaxial cable 20, in an exploded view.
