Description

Die Erfindung betrifft eine Steckverbinderanordnung, die aus einem Steckverbinder und einem daran angeschlossenen Kabel besteht. Das Kabel hat mindestens einen Innenleiter und einen den Innenleiter umlaufenden Außenleiter, wobei der Außenleiter elektrisch mit einem Außenleitergehäuse des Steckverbinders verbunden ist.The invention relates to a connector assembly consisting of a connector and a cable connected thereto. The cable has at least one inner conductor and an outer conductor surrounding the inner conductor, wherein the outer conductor is electrically connected to an outer conductor housing of the connector.

Der Steckverbinder hat 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 der Innenleiter des Kabels elektrisch mit einem Innenleiterteil des Steckverbinders wie etwa einem Kontaktstift oder einer Kontaktbuchse verbunden und der Außenleiter des Kabels ist elektrisch mit dem das Innenleiterteil umlaufenden Außenleitergehäuse des Steckverbinders verbunden, so dass vorzugsweise von dem Kabel bis zu dem steckseitigen Ende des Steckverbinders eine durchgehende Schirmung gebildet ist.The connector has a plug-in end for connecting the connector to a mating connector and a cable-side end to which the cable is attached (preferably non-releasably by soldering or crimping). In this case, the inner conductor of the cable is electrically connected to an inner conductor part of the connector such as a contact pin or a female contact and the outer conductor of the cable is electrically connected to the inner conductor part circumferential outer conductor housing of the connector, so preferably from the cable to the plug-side end of the connector a continuous shield is formed.

Es ist bekannt, zum Herstellen der Verbindung zwischen dem Steckverbinder und dem Kabel das aus einem elektrisch leitenden Material bestehende und zumindest abschnittweise hülsenförmige Außenleitergehäuse mit einem axialen Endabschnitt des Außenleiters zu 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 Außenleiter verpresst.It is known to crimp or compress the existing of an electrically conductive material and at least partially sleeve-shaped outer conductor housing with an axial end portion of the outer conductor for establishing the connection between the connector and the cable. 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 surrounding outer conductor housing is pressed with the outer conductor.

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.

Die Druckschrift US 2003/087553 A1 beschreibt eine Anordnung aus einem Koaxialkabel und einer Verbinder, wobei der Außenleiter des Kabels um eine Hülse zurückgeschlagen ist, und wobei ein weiteres Hülsenteil vorgesehen ist.The publication US 2003/087553 A1 describes an arrangement of a coaxial cable and a connector, wherein the outer conductor of the cable is folded back around a sleeve, and wherein a further sleeve part is provided.

In Anbetracht der beschriebenen Probleme ist es die Aufgabe der vorliegenden Erfindung, eine stabil und zugfest eingerichtete Verbindung zwischen dem Steckverbinder und dem Kabel bereitzustellen, die ferner möglichst über ihre gesamte Erstreckung in Kabellängsrichtung optimal elektrisch angepasst ist.In view of the problems described, it is the object of the present invention to provide a stable and zugfest established connection between the connector and the cable, which is further optimally adapted electrically as possible over its entire extension in the cable longitudinal direction.

Diese Aufgabe wird durch eine Steckverbinderanordnung gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.This object is achieved by a connector assembly according to claim 1. Advantageous developments of the invention are described in the dependent claims.

Die erfindungsgemäße Steckverbinderanordnung weist ein den Innenleiter umlaufendes Hülsenteil auf, das an das vordere axiale Ende des Außenleiters angrenzt und den Außenleiter (bzw. eine Innenleiterschirmung) damit in axialer Richtung (in Richtung auf das steckseitige Ende des Steckverbinders) fortsetzt. Wichtig dabei ist, dass das Hülsenteil etwa denselben Innendurchmesser hat wie der Außenleiter des Kabels. Mit anderen Worten umläuft das Hülsenteil den Innenleiter des Kabels in einem außenleiterfreien Bereich, der an dem vorderen Kabelende vorgesehen ist, um eine Verbindung des Innenleiters mit dem Innenleiterteil des Steckverbinders zu ermöglichen. Vorzugsweise ist das Hülsenteil zwischen dem vorderen axialen Ende des Außenleiters und einem axialen Anschlag des Steckverbinders vorgesehen. Die erfindungsgemäße Steckverbinderanordnung weist die weiteren in Patentanspruch 1 angegebenen Merkmale auf.The connector assembly according to the invention has a sleeve portion surrounding the inner conductor, which adjoins the front axial end of the outer conductor and thus continues the outer conductor (or an inner conductor shield) in the axial direction (in the direction of the plug-side end of the connector). It is important that the sleeve part has approximately the same inner diameter as the outer conductor of the cable. In other words, the sleeve part circumscribes the inner conductor of the cable in an outer conductor-free region, which is provided at the front cable end in order to allow a connection of the inner conductor to the inner conductor part of the connector. Preferably, the sleeve member is provided between the front axial end of the outer conductor and an axial stop of the connector. The connector assembly according to the invention has the further specified in claim 1 features.

Die Erfindung geht auf die Erkenntnis zurück, dass zum Erhalt einer in Kabellängsrichtung gleichbleibenden Impedanz bei unveränderter Kabelgeometrie auch ein im Wesentlichen gleichbleibender Abstand zwischen dem Innenleiter und dem Außenleiter des Kabels erforderlich ist. So führt eine Vergrößerung des Abstands zwischen Innenleiter und Außenleiter des Kabels 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 Außenleiters vor. Erfindungsgemäß wird dagegen durch das Hülsenteil die Schirmung auch im Bereich des vorderen axialen Endes des Außenleiters mit gleichbleibender Entfernung zum Innenleiter fortgeführt, so dass keine Impedanzänderung in diesem Bereich auftritt.The invention is based on the knowledge that in order to obtain a constant impedance in the cable longitudinal direction with unchanged cable geometry, a substantially constant distance between the inner conductor and the outer conductor of the cable is required. Thus, an increase in the distance between the inner conductor and the outer conductor of the cable 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 regularly at the front axial end of the outer conductor before. According to the invention, however, the shield is continued by the sleeve part in the region of the front axial end of the outer conductor with a constant distance to the inner conductor, so that no impedance change occurs in this area.

Vorzugsweise liegt dabei das Verhältnis zwischen dem Innendurchmesser des Hülsenteils und dem Innendurchmesser des Außenleiters zwischen 0,9 und 1,2, besonders bevorzugt zwischen 0,95 und 1,1, insbesondere zwischen 0,98 und 1,05, so dass der Außenleiter an seinem axialen vorderen Ende praktisch stufenfrei in das Hülsenteil übergeht bzw. sogar praktisch stufenfrei daran anliegt. Ein Sprung des Abstands zwischen Innenleiter und dessen Schirmung am vorderen Ende des Außenleiters wird auf diese Weise zuverlässig verhindert.Preferably, the ratio between the inner diameter of the sleeve part and the inner diameter of the outer conductor between 0.9 and 1.2, more preferably between 0.95 and 1.1, in particular between 0.98 and 1.05, so that the outer conductor to its axial front end virtually step-free merges into the sleeve part and even practically rests step-free thereon. A jump in the distance between the inner conductor and its shielding at the front end of the outer conductor is reliably prevented in this way.

Das Hülsenteil kann einteilig als geschlossene Zylindermantelhülse gebildet sein und wird in diesem Fall ausgehend von dem vorderen Kabelende über den Innenleiter (bzw. über mehrere Innenleiter) in Richtung auf das vordere axiale Ende des Außenleiters aufgeschoben. Alternativ kann das Hülsenteil auch als offene Hülse gebildet sein, die erst durch einen Pressvorgang beim Anbringen der Hülse geschlossen wird und den Innenleiter dann ringsum umläuft. Weiter alternativ kann das Hülsenteil aus zwei oder mehr Hülsenschalen bestehen, die von verschiedenen Seiten auf den Innenleiter aufgesetzt werden. Vorzugsweise ist das Hülsenteil in Form eines im Wesentlichen zylindermantelförmigen Rohrabschnitts bzw. Rohrs gebildet und besteht aus einem leitenden Material wie etwa einem Metall, insbesondere aus Kupfer, Silber o.dgl.The sleeve part may be formed integrally as a closed cylinder jacket sleeve and is pushed in this case, starting from the front end of the cable via the inner conductor (or via a plurality of inner conductor) in the direction of the front axial end of the outer conductor. Alternatively, the sleeve part can also be formed as an open sleeve, which is closed only by a pressing operation when attaching the sleeve and then rotates the inner conductor all around. As an alternative, the sleeve part can consist of two or more sleeve shells, which are placed on the inner conductor from different sides. Preferably, the sleeve part is formed in the form of a substantially cylinder-jacket-shaped pipe section and consists of a conductive material such as a metal, in particular of copper, silver or the like.

Zusätzlich zu dem Hülsenteil weist das Kabel eine den Innenleiter umlaufende Stützhülse auf der dem Steckverbinder abgewandten Seite des Hülsenteils auf. Insbesondere wenn die Stützhülse radial außen auf dem Außenleiter angeordnet ist, hat es sich als vorteilhaft erwiesen, dass der Innendurchmesser der Stützhülse etwas größer ist als der Innendurchmesser des Hülsenteils, so die Stützhülse problemlos außen auf den Außenleiter aufbringbar ist, während das Hülsenteil zwar außen auf den Innenleiter, nicht aber außen auf den Außenleiter aufbringbar ist. Dadurch ist über den gesamten Verlauf des Kabelendes ein im Wesentlichen konstanter Abstand zwischen dem Innenleiter und der Schirmung sichergestellt. Anders als die Stützhülse ist das Hülsenteil axial neben dem Außenleiter, vorzugsweise aber nicht in derselben Radialebene wie der Außenleiter angeordnet, so dass sich Außenleiter und Hülsenteil in Kabellängsrichtung nicht überlappen.In addition to the sleeve part, the cable has an inner sleeve surrounding the support sleeve on the side facing away from the connector of the sleeve part. In particular, when the support sleeve is arranged radially outward on the outer conductor, it has proved to be advantageous that the inner diameter of the support sleeve is slightly larger than the inner diameter of the sleeve part, so the support sleeve is easily applied externally on the outer conductor, while the sleeve part while on the outside the inner conductor, but not outside of the outer conductor can be applied. As a result, a substantially constant distance between the inner conductor and the shield is ensured over the entire course of the cable end. Unlike the support sleeve, the sleeve part is arranged axially next to the outer conductor, but preferably not in the same radial plane as the outer conductor, so that outer conductor and sleeve part do not overlap in the cable longitudinal direction.

Die Stützhülse ist zum Halten und Fixieren des vorderen Endes des Außenleiters vorgesehen, insbesondere wenn der Außenleiter in Form eines Drahtgeflechts o.dgl. vorgesehen ist. In diesem Zusammenhang hat es sich als vorteilhaft erwiesen, dass das steckverbinderseitige Ende der Stützhülse in Kabellängsrichtung im Wesentlichen mit dem axialen vorderen Ende des Außenleiters zusammenfällt, so dass die Stützhülse den Außenleiter bis hin zu seinem vorderen axialen Ende stützt und hält.The support sleeve is provided for holding and fixing the front end of the outer conductor, in particular when the outer conductor in the form of a wire mesh or the like. is provided. In this context, it has proven to be advantageous that the connector-side end of the support sleeve in the cable longitudinal direction substantially coincides with the axial front end of the outer conductor, so that the support sleeve supports the outer conductor up to its front axial end and holds.

Im Hinblick auf eine optimale elektrische und mechanische Verbindung zwischen dem Außenleiter, der Stützhülse und dem Außenleitergehäuse ist der Außenleiter um die Stützhülse herum zurückgefaltet. In diesem Fall kann durch Verpressung eine besonders dauerhafte und stabile Crimpverbindung zwischen dem vorzugsweise als Drahtgeflecht gebildeten Außenleiter und der Stützhülse bzw. dem Außenleitergehäuse hergestellt werden.In view of optimum electrical and mechanical connection between the outer conductor, the support sleeve and the outer conductor housing, the outer conductor is folded back around the support sleeve. In this case, by pressing a particularly durable and stable crimp connection between the preferably formed as a wire mesh outer conductor and the support sleeve and the outer conductor housing can be made.

Vorzugsweise ist der Abstand zwischen dem kabelseitigen Ende des Hülsenteils und dem steckverbinderseitigen Ende der Stützhülse bzw. dem daran umgeschlagenen Außenleiter kleiner als 2 mm, insbesondere kleiner als 1 mm. Besonders vorteilhaft ist es, wenn das kabelseitige Ende des Hülsenteils unmittelbar an dem steckverbinderseitigen Ende der Stützhülse bzw. an dem daran umgeschlagenen Außenleiter anliegt. In diesem Fall ist eine elektrische Verbindung zwischen dem Außenleiter und dem Außenleitergehäuse nämlich nicht nur unmittelbar hergestellt, sondern auch mittelbar über das Hülsenteil.Preferably, the distance between the cable-side end of the sleeve part and the connector-side end of the support sleeve or the outer conductor folded over it is less than 2 mm, in particular less than 1 mm. It is particularly advantageous if the cable-side end of the sleeve part rests directly on the connector-side end of the support sleeve or on the outer conductor folded over it. In this case, an electrical connection between the outer conductor and the outer conductor housing is not only directly produced, but also indirectly via the sleeve part.

Bei einer besonders bevorzugten Ausführungsform der Erfindung sind das Hülsenteil und/oder die Stützhülse zumindest abschnittsweise in Form einer zylindermantelförmigen Hülse wie etwa einer Crimphülse gebildet, die entweder als einzelnes Teil gebildet sein kann oder aus mehreren Zylinderschalenteilen besteht. Der Innendurchmesser des Hülsenteils kann an den Außendurchmesser einer den (oder die) Innenleiter umgebenden Isolierung angepasst sein und/oder der Innendurchmesser der Stützhülse kann an den Außendurchmesser des Außenleiters angepasst sein.In a particularly preferred embodiment of the invention, the sleeve part and / or the support sleeve are at least partially formed in the form of a cylinder jacket sleeve such as a crimp sleeve, which may be formed either as a single part or consists of several cylinder shell parts. The inner diameter of the sleeve part can be adapted to the outer diameter of an insulation surrounding the inner conductor (s) and / or the inner diameter of the support sleeve can be adapted to the outer diameter of the outer conductor.

Das Außenleitergehäuse weist einen Hülsenabschnitt zur Aufnahme des Kabelendes auf, wobei eine Wand des Hülsenabschnitts radial außen an dem Hülsenteil und an der Stützhülse anliegt. Mit anderen Worten ist der Hülsenabschnitt zur Aufnahme des Kabelendes zumindest bis hin zu der Stützhülse eingerichtet. Dadurch wird zum einen eine durchgängige Schirmung des Innenleiters sichergestellt. Zum anderen ist auf einfache Weise durch Anwendung eine radialen Presskraft von außen auf die Wand des Hülsenabschnitts eine Verpressung des Hülsenabschnitts mit dem Kabel möglich. Dadurch ist das Kabel zugfest an dem Steckverbinder gehalten.The outer conductor housing has a sleeve portion for receiving the cable end, wherein a wall of the sleeve portion rests radially outward on the sleeve part and on the support sleeve. In other words, the sleeve portion is adapted for receiving the cable end at least up to the support sleeve. As a result, on the one hand a continuous shielding of the inner conductor is ensured. On the other hand, a compression of the sleeve portion with the cable is easily possible by applying a radial pressing force from the outside to the wall of the sleeve portion. As a result, the cable is held tensile strength on the connector.

Gemäß einem besonders wichtigen Gesichtspunkt der Erfindung weist die Steckverbinderanordnung mehrere Crimpverbindungen zwischen dem Hülsenabschnitt des Außenleitergehäuses und dem Kabel auf Höhe des Hülsenteils und auf Höhe der Stützhülse auf. Als besonders vorteilhaft hat es sich erwiesen, eine erste Crimpverbindung im Bereich des Hülsenteils und mindestens eine zweite Crimpverbindung im Bereich der Stützhülse vorzusehen. Dadurch werden zum einen ein guter elektrischer Kontakt und eine stabile mechanische Verbindung zwischen dem Außenleiter und dem Außenleitergehäuse garantiert. Zum anderen wird sichergestellt, dass sowohl die Stützhülse als auch das Hülsenteil sowohl gegenüber dem Außenleiter als auch gegenüber dem Innenleiter ortsfest fixiert sind.According to a particularly important aspect of the invention, the connector assembly has a plurality of crimp connections between the sleeve portion of the outer conductor housing and the cable at the level of the sleeve part and at the height of the support sleeve. It has proven particularly advantageous to provide a first crimp connection in the region of the sleeve part and at least one second crimp connection in the region of the support sleeve. This guarantees, on the one hand, good electrical contact and a stable mechanical connection between the outer conductor and the outer conductor housing. On the other hand, it is ensured that both the support sleeve and the sleeve part are fixed in position both with respect to the outer conductor and with respect to the inner conductor.

Im Hinblick auf einen optimalen Verlauf des Wellenwiderstands hat es sich als zweckmäßig erwiesen, dass das steckverbinderseitige Ende des Hülsenteils unmittelbar an einem axialen Anschlag des Außenleitergehäuses anliegt. Ausgehend von dem axialen Anschlag hat das Außenleitergehäuse in Richtung auf das steckseitige Ende des Steckverbinders vorzugsweise einen Innendurchmesser, der im Wesentlichen demjenigen des Außenleiters des Kabels entspricht. Der Abstand zwischen dem axialen Anschlag des Steckverbinders und dem vorderen axialen Ende des Außenleiters entspricht vorzugsweise im Wesentlichen der axialen Abmessung des Hülsenteils. Im Hinblick auf eine kostengünstige Herstellbarkeit und im Hinblick auf ein vergleichsweise leichtes Kabelgewicht hat es sich als vorteilhaft erwiesen, dass der Außenleiter in Form eines Geflechts wie etwa eines Drahtgeflechts gebildet ist. Ein Drahtgeflecht ist ferner besonders gut zum Herstellen einer Pressverbindung geeignet und eignet sich zum Zurückfalten über die Stützhülse.With regard to an optimal course of the characteristic impedance, it has proved to be expedient that the connector-side end of the sleeve part rests directly against an axial stop of the outer conductor housing. Starting from the axial stop, the outer conductor housing preferably has, in the direction of the plug-side end of the plug connector, an inner diameter which essentially corresponds to that of the outer conductor of the cable. The distance between the axial Stop of the connector and the front axial end of the outer conductor preferably corresponds substantially to the axial dimension of the sleeve part. In view of a cost-effective manufacturability and in view of a comparatively lightweight cable weight, it has proved to be advantageous that the outer conductor is formed in the form of a braid such as a wire mesh. A wire mesh is also particularly well suited for making a press connection and is suitable for folding back over the support sleeve.

Andererseits kann der Innenleiter in Form einer von einem Dielektrikum umgebenen Seele oder eines oder mehrerer jeweils isolierter Adern gebildet sein. Bspw. sind ein oder mehrere Innenleiterpaare zum Übertragen eines oder mehrerer differentieller Signale über das Kabel vorgesehen. Zwei Innenleiterpaare können bspw. in einer Sternviereranordnung verlaufen. Vorzugsweise sind alle Innenleiter von dem gemeinsamen Außenleiter in Form eines Drahtgeflechts umlaufen.On the other hand, the inner conductor may be formed in the form of a core surrounded by a dielectric or one or more respectively insulated wires. For example. For example, one or more inner conductor pairs are provided for transmitting one or more differential signals over the cable. Two pairs of inner conductors can, for example, run in a star quad array. Preferably, all inner conductors of the common outer conductor in the form of a wire mesh circulate.

Das Kabel kann ein Koaxialkabel, ein geschirmtes Twisted-Pair-Kabel, ein geschirmtes Stern-Viererkabel o. dgl. sein. Derartige Kabel sind regelmäßig zur Übertragung von HF-Signalen vorgesehen, wobei in diesem Fall eine optimale elektrische Anpassung besonders wichtig ist, um eine Verfälschung des Signalverlaufs zu vermeiden.The cable may be a coaxial cable, a shielded twisted pair cable, a shielded star quad or the like. Such cables are regularly provided for the transmission of RF signals, in which case optimum electrical adjustment is particularly important in order to avoid distortion of the signal waveform.

In der nun folgenden Beschreibung wird die Erfindung unter Bezugnahme auf die beigefügten Zeichnungen erläutert. Dabei zeigt:

Fig. 2
eine Querschnittansicht durch die in Fig. 1 gezeigte Steckverbinderanordnung (Schnittebene S).
In the following description, the invention will be explained with reference to the accompanying drawings. Showing:
Fig. 1
a partially shown in longitudinal section schematic side view of a connector assembly according to the invention, and
Fig. 2
a cross-sectional view through the in Fig. 1 shown connector assembly (section plane S).

Die in Fig. 1 schematisch dargestellte erfindungsgemäße Steckverbinderanordnung 10 besteht aus eine Steckverbinder 20 wie etwa einem Koaxialstecker und einem daran angeschlossenen Kabel 30 wie etwa einem Koaxialkabel, einem Sternviererkabel o.dgl.In the Fig. 1 schematically illustrated connector assembly 10 according to the invention consists of a connector 20 such as a coaxial connector and a cable connected thereto 30 such as a coaxial cable, a star quad cable or the like.

Der Steckverbinder 20 ist zum Verbinden mit einem Gegensteckverbinder wie etwa einem Buchsenteil an seinem in Fig. 1 links dargestellten steckseitigen Ende eingerichtet. An dem in Fig. 1 rechts dargestellten kabelseitigen Ende des Steckverbinders 20 ist das Kabel 30 zugfest befestigt.The connector 20 is for connecting to a mating connector such as a female connector at its in Fig. 1 on the left side of the plug shown. At the in Fig. 1 shown on the cable-side end of the connector 20, the cable 30 is attached tensile strength.

Das Kabel 30 weist (hier beispielhaft) insgesamt vier verseilte Innenleiter 32 in Form von jeweils mit einer Isolierung versehenen Adern auf. Jeweils zwei Innenleiter 32 bilden ein differentielles Leiterpaar zu Übertragung differentieller Signale wie etwa HF-Signale o.dgl. Die vier Innenleiter 32 sind von einem gemeinsamen Außenleiter 34 in Form eines Drahtgeflechts umgeben, das die Innenleiter 32 nach außen hin abschirmt. Das Drahtgeflecht liegt außen an der Aderisolierung an. Der Außenleiter 34 ist außen koaxial von einem Kabelmantel 80 aus einem nichtleitenden Material wie etwa einem Kunststoff umgeben.The cable 30 has (here by way of example) a total of four stranded inner conductors 32 in the form of cores each provided with an insulation. In each case two inner conductors 32 form a differential pair of conductors for transmission of differential signals such as RF signals or the like. The four inner conductors 32 are surrounded by a common outer conductor 34 in the form of a wire mesh, which shields the inner conductor 32 to the outside. The wire mesh lies on the outside of the core insulation. The outer conductor 34 is externally coaxially surrounded by a cable sheath 80 made of a non-conductive material such as a plastic.

Die Innenleiter 32 sind jeweils an ihrem dem Steckverbinder 20 zugewandten vorderen Ende mit Innenleiterkontakten (nicht gezeigt) des Steckverbinders 20 elektrisch verbunden. Der Außenleiter 34 an seinem dem Steckverbinder 20 zugewandten vorderen Endabschnitt mit einem Außenleitergehäuse 24 des Steckverbinders elektrisch verbunden, der die Schirmung der Innenleiter 32 bis hin zu dem steckseitigen Ende des Steckverbinders 20 fortsetzt.The inner conductors 32 are each electrically connected at their front end facing the connector 20 with inner conductor contacts (not shown) of the connector 20. The outer conductor 34 is electrically connected at its plug connector 20 facing the front end portion with an outer conductor housing 24 of the connector, which continues the shielding of the inner conductor 32 up to the plug-side end of the connector 20.

Das vordere Kabelende ist in einem rohrartigen Hülsenabschnitt 26 des Außenleitergehäuses 24 aufgenommen, der ausgehend von einem Basisabschnitt des Außenleitergehäuses 24 kabelseitig vorsteht. Der Innendurchmesser des Hülsenabschnitts 26 entspricht im Wesentlichen dem Außendurchmesser des Kabelmantels 30, so dass das Kabel 30 in die durch den Hülsenabschnitt 26 gebildete Öffnung einführbar ist.The front cable end is received in a tubular sleeve portion 26 of the outer conductor housing 24, which projects from the cable side, starting from a base portion of the outer conductor housing 24. The inner diameter of the sleeve portion 26 substantially corresponds to the outer diameter of the cable sheath 30, so that the cable 30 is insertable into the opening formed by the sleeve portion 26.

An dem vorderen Ende des Kabels 30 ist der Kabelmantel 80 entfernt, so dass der Außenleiter 34 freigelegt ist und in elektrischen Kontakt mit der Wand des Hülsenabschnitts 26 gebracht werden kann.At the front end of the cable 30, the cable sheath 80 is removed, so that the outer conductor 34 is exposed and can be brought into electrical contact with the wall of the sleeve portion 26.

Zur besseren Fixierung des vorderen axialen Endes A des Außenleiters 34 und insbesondere zum Verhindern einer Beschädigung der Innenleiter 32 bei der Herstellung einer Crimpverbindung zwischen dem Außenleiter 34 und dem Außenleitergehäuse 24 ist eine Stützhülse 60 auf einem vorderen Abschnitt des Außenleiters 34 vorgesehen. Das Drahtgeflecht des Außenleiters 34 ist um das vordere Ende der Stützhülse herum zurückgeschlagen, so dass das Drahtgeflecht des Außenleiters 34 an der Stützhülse 60 innen und außen anliegt. Damit bildet das an dem vorderen Ende der Stützhülse 60 anliegende Drahtgeflecht das vordere axiale Ende A des Außenleiters 34.For better fixing of the front axial end A of the outer conductor 34 and in particular for preventing damage to the inner conductor 32 during manufacture a crimp connection between the outer conductor 34 and the outer conductor housing 24, a support sleeve 60 is provided on a front portion of the outer conductor 34. The wire mesh of the outer conductor 34 is folded back around the front end of the support sleeve around, so that the wire mesh of the outer conductor 34 rests against the support sleeve 60 inside and outside. Thus, the wire mesh at the front end of the support sleeve 60 forms the front axial end A of the outer conductor 34th

Wie in Fig. 1 deutlich dargestellt ist, ist zwischen dem axialen Ende A des Außenleiters 34 und einem Anschlag 25 des Steckverbinders ein Raum ohne Kabelaußenleiter gebildet, in dem der Abstand zwischen den Innenleitern 32 und dem Hülsenabschnitt 26 erheblich ist. Dieser sich am vorderen Ende A des Außenleiters 34 abrupt ändernde Abstand zwischen Innenleiter und Schirmung führt bei herkömmlichen Steckverbinderanordnungen zu einem induktiven Bereich mit unzureichender elektrischer Anpassung.As in Fig. 1 is clearly shown, a space without cable outer conductor is formed between the axial end A of the outer conductor 34 and a stop 25 of the connector, in which the distance between the inner conductors 32 and the sleeve portion 26 is significant. This at the front end A of the outer conductor 34 abruptly changing distance between the inner conductor and shield leads in conventional connector assemblies to an inductive region with insufficient electrical adaptation.

In diesem Raum ohne Kabelaußenleiter ist erfindungsgemäß ein Hülsenteil 50 radial außen an den Innenleitern 32 angeordnet, das aus einem elektrisch leitenden Material besteht. Der Innendurchmesser des Hülsenteils D entspricht im Wesentlichen dem Durchmesser des Außenleiters 34, so dass ausgehend von dem axialen Ende des Außenleiters 34 bis hin zu dem steckverbinderseitigen Ende des Hülsenteils 50 kein Sprung im Innendurchmesser der Abschirmung vorhanden ist. Das kabelseitige Ende des Hülsenteils 50 liegt unmittelbar an dem axialen Ende A des Außenleiters 34 an.In this space without cable outer conductor according to the invention a sleeve member 50 is disposed radially outwardly of the inner conductors 32, which consists of an electrically conductive material. The inner diameter of the sleeve part D substantially corresponds to the diameter of the outer conductor 34, so that starting from the axial end of the outer conductor 34 up to the connector-side end of the sleeve part 50 no jump in the inner diameter of the shield is present. The cable-side end of the sleeve part 50 abuts directly on the axial end A of the outer conductor 34.

Andererseits liegt das steckverbinderseitige Ende des Hülsenteils 60 vorzugsweise an einem axialen Anschlag 25 des Außenleitergehäuses 24 an. Ausgehend von dem Anschlag 25 ist ein Außenleiterbereich 28 des Außenleitergehäuses 24 vorgesehen, in dem der Innendurchmesser des Außenleitergehäuses 24 im Wesentlichen dem Innendurchmesser D des Außenleiters 34 entspricht. Damit wird die Schirmung in Richtung auf das steckseitige Ende des Steckverbinders unter konstantem Abstand zu den Innenleitern fortgesetzt.On the other hand, the connector-side end of the sleeve part 60 preferably abuts against an axial stop 25 of the outer conductor housing 24. Starting from the stop 25, an outer conductor region 28 of the outer conductor housing 24 is provided, in which the inner diameter of the outer conductor housing 24 essentially corresponds to the inner diameter D of the outer conductor 34. Thus, the shielding is continued in the direction of the plug-side end of the connector at a constant distance from the inner conductors.

In Fig. 2 ist die erfindungsgemäße Steckverbinderanordnung in der durch das Hülsenteil 50 verlaufenden Schnittebene S im Querschnitt gezeigt. Es sind deutlich die von dem Hülsenteil 50 umgebenen vier Innenleiter 32 dargestellt. Das Hülsenteil 50 wird wiederum von dem Hülsenabschnitt 26 des Außenleitergehäuses 24 umlaufen. Durch Anwendung einer radialen Presskraft von außen auf den Hülsenabschnitt 26 wird die Wand des Hülsenabschnitts 26 von außen an das Hülsenteil 50 angepresst.In Fig. 2 the connector assembly according to the invention is shown in the plane passing through the sleeve member 50 cutting plane S in cross section. Clearly, the four inner conductors 32 surrounded by the sleeve part 50 are shown. The sleeve part 50 is turn around from the sleeve portion 26 of the outer conductor housing 24. By applying a radial pressing force from the outside to the sleeve portion 26, the wall of the sleeve portion 26 is pressed from the outside to the sleeve part 50.

Die Erfindung ist nicht auf die beschriebene Ausführungsform beschränkt. Insbesondere kann das Hülsenteil auch anders geformt sein. Wichtig ist insbesondere, dass das Hülsenteil den Außenleiter ausgehend von dessen axialem Ende in Richtung auf das vordere Kabelende unter Beibehaltung des Abstands zwischen Innenleitern und Schirmung fortsetzt.The invention is not limited to the described embodiment. In particular, the sleeve part can also be shaped differently. It is particularly important that the sleeve part continues the outer conductor, starting from the axial end in the direction of the front cable end while maintaining the distance between inner conductors and shielding.
