Description

Die vorliegende Erfindung betrifft einen Steckverbinder zum Übertragen von elektrischen Strömen mit einem steckseitigen Ende, welches zum Zusammenstecken mit einem Gegenstecker ausgebildet ist, einem kabelseitigen Ende, welches zum elektrischen und mechanischen Verbinden mit einem Kabel, insbesondere einem Kabel mit Abschirmung und mindestens zwei Leitungen innerhalb der Abschirmung, ausgebildet ist, einem Gehäuse, und mit mindestens zwei Innenleiterteilen, die von einem Isolierteil mindestens teilweise innerhalb des Gehäuses gehalten und voneinander elektrisch isoliert sind und jeweilige Kontaktflächen zum elektrischen Kontaktieren mit entsprechenden Leiterteilen in dem Gegenstecker ausbilden, wobei jedes Innenleiterteil einen Kontaktabschnitt aufweist, welcher sich von der Kontaktfläche in Richtung des kabelseitigen Endes des Steckverbinders in axialer Richtung erstreckt und zum elektrischen und mechanischen verbinden mit jeweils einer Leitung des Kabels ausgebildet ist, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a connector for transmitting electrical currents with a plug-side end, which is designed for mating with a mating connector, a cable end, which for electrical and mechanical connection to a cable, in particular a cable with shielding and at least two lines within the Shield is formed, a housing, and having at least two inner conductor parts which are held by an insulating at least partially within the housing and electrically insulated from each other and form respective contact surfaces for electrical contacting with corresponding conductor parts in the mating connector, each inner conductor part having a contact portion, which extends from the contact surface in the direction of the cable-side end of the connector in the axial direction and is designed for electrical and mechanical connection with one line of the cable, according to the preamble of claim 1.

Zwei- oder Mehrpolige Steckverbinder für elektrische Steckverbindungen benötigen eine genaue Ausrichtung von Stecker und Gegenstecker, damit die jeweiligen Leiter des Steckverbinders mit dem jeweils richtigen Leiter des Gegensteckers in elektrischen und mechanischen Kontakt kommen. Hierbei sind Steckverbinder und Gegensteckverbinder nicht frei relativ zueinander drehbar. In manchen Anwendungen kommt es jedoch nach dem Zusammenstecken von einem an einem Kabelende angeordneten Steckverbinder mit einem beispielsweise fixiert an einem Gehäuse angeordneten Gegensteckverbinder zu einer Bewegung des Kabels oder der Steckverbinder muss mit dem Kabel entsprechend verdreht werden, damit dieser in den Gegensteckverbinder entsprechend der richtigen Polung einsteckbar ist. Dies führt zu unerwünschten mechanischen Spannungskräften im Steckverbinder und im Kabel, die beispielsweise zu einem Bruch einer Abschirmung des Kabels führen und somit eine elektromagnetische Abschirmung der Steckverbindung beeinträchtigen können.Two-pole or multi-pole connectors for electrical connections require precise alignment of the plug and mating connector, so that the respective conductors of the connector come into electrical and mechanical contact with the respectively correct conductor of the mating connector. In this case, connectors and mating connectors are not freely rotatable relative to each other. In some Applications, however, it comes after mating of a arranged at one end of a cable connector with an example fixed to a housing mating connector to a movement of the cable or the connector must be rotated accordingly with the cable so that it can be inserted into the mating connector according to the correct polarity , This leads to undesirable mechanical stress forces in the connector and in the cable, for example, lead to a breakage of a shield of the cable and thus can affect an electromagnetic shielding of the connector.

Zum Herstellen von mehrpoligen Steckverbindungen, wobei Stecker und Gegenstecker frei relativ zueinander drehbar sind, ist beispielsweise aus der DD 236420 A1 ein mehrpoliger Klinkenstecker bekannt. Hierbei ist am Klingenstecker eine in Umfangsrichtung umlaufende Nut ausgebildet, in die eine in einem Gegensteckverbinder angeordnete Kontaktfeder einrastet und dadurch eine entsprechende Kontaktkraft herstellt sowie den Klinkenstecker im Gegensteckverbinder verriegelt. Die Kontaktfeder ist dabei einer der Leiter im Gegensteckverbinder und die Nut ist in einer der Kontaktflächen des Klinkensteckers ausgebildet. Vorteile der Klinkenverbindung sind die einfache Handhabung bei Platz sparender Bauform. Nachteile sind vor allem der kurzschließende Steckvorgang und die relativ schlechte Kontaktqualität. Wenn die Federspannung der Kontaktfeder im Gegensteckverbinder mit der Zeit nachlässt, dann wird nicht nur der elektrische Kontakt schlechter, sondern auch die mechanische Steckfestigkeit. Die fehlende mechanische Verriegelung kann im Einzelfall ein Nachteil sein, wenn die sich unerwünscht lösende Steckverbindung zu Schäden führen kann, wie beispielsweise beim Lautsprecheranschluss eines Röhren-Gitarrenverstärkers.For the manufacture of multipolar connectors, wherein plug and mating connector are freely rotatable relative to each other, for example, from DD 236420 A1 a multipole jack known. Here, a circumferentially circumferential groove is formed on the blade connector into which a arranged in a mating connector contact spring engages and thereby produces a corresponding contact force and locks the jack plug in the mating connector. The contact spring is one of the conductors in the mating connector and the groove is formed in one of the contact surfaces of the jack plug. Advantages of the latch connection are the ease of use in a space-saving design. Disadvantages are above all the short-circuiting plugging operation and the relatively poor contact quality. If the spring tension of the contact spring in the mating connector deteriorates over time, then not only the electrical contact is worse, but also the mechanical plug strength. The lack of mechanical locking can be a disadvantage in individual cases, if the undesirable loose connector can cause damage, such as the speaker connection of a tube guitar amplifier.

Die Kontaktbelastung einer Klinkensteckverbindung beträgt beispielsweise bei den 6,35-mm-Buchsen und -Kupplungen bis zu 3 A, die Schaltlast 0,5 A bei 50 V. Daher sind Klinkenstecker nicht für die Übertragung von hohen elektrischen Strömen mit Stromstärken von beispielsweise 20A oder mehr bei hohen elektrischen Spannungen von 100 V oder mehr geeignet.The contact load of a jack connector, for example, in the 6.35 mm sockets and couplings up to 3 A, the switching load 0.5 A at 50 V. Therefore, jack plugs are not for the transmission of high electrical currents with currents of, for example 20A or more suitable at high electrical voltages of 100 V or more.

Aus der EP 0 067 727 A1 ist eine Kabelabschlussvorrichtung bekannt, mit dem ein Doppelkoaxialkabel mit einem Steckverbinder verbunden wird. Diese Kabelabschlussvorrichtung weist zwei Innenleiterteile auf, die von einem Isolierteil innderhalb eines Gehäuses gehalten und elektrisch voneinander isoliert sind.From the EP 0 067 727 A1 a cable termination device is known, with which a Doppelkoaxialkabel is connected to a connector. This cable termination device has two inner conductor parts, which are held by an insulating part within a housing and are electrically insulated from each other.

Within the plug portion, an inner conductor contact is arranged and radially on the plug portion, a C-shaped outer conductor contact is arranged.

Aus der WO 2008/060470 A2 ist ein Mehrfachsignal-Steckverbinder mit einem einzelnen Kontakt bekannt. Der einzelne Kontakt weist zwei elektrisch voneinander isolierte elektrische Leiter auf, die zwei getrennte elektrische Kontaktflächen zur Verfügung stellen. Hierdurch können zwei verschiedene elektrische' Signale gleichzeitig über den einzelnen Kontakt übertragen werden.From the WO 2008/060470 A2 For example, a single-contact multi-signal connector is known. The single contact has two electrically insulated electrical conductors which provide two separate electrical contact surfaces. As a result, two different electrical 'signals can be transmitted simultaneously via the individual contact.

In einer Hülse ist ein rohrförmiges Element angeordnet, welches elektrische Verbinder aus einem federelastischen Werkstoff trägt. Jeweilige Leitungsdrähte sind über Nuten am Außenumfang der Hülse zu den elektrsichen Verbindern geführt. Ein in die Klinkensteckerbuchse eingesteckter und die elektrischen Verbinder elektrisch kontaktierender Klinkenstecker kann relativ zur Klinkensteckerbuchse frei gedreht werden.From the US 3,246,282 an electrical connector in the form of a jack socket known. In a sleeve, a tubular element is arranged, which carries electrical connector made of a resilient material. Respective lead wires are routed via grooves on the outer circumference of the sleeve to the electrical connectors. An inserted into the jack socket and the electrical connector electrically contacting jack plug can be freely rotated relative to the jack socket.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder o.g. Art zur Verfügung zu stellen, welcher relativ zu einem Gegensteckverbinder frei drehbar ist und gleichzeitig die Übertragung von hohen Stromstärken erlaubt.The invention has the object of providing a connector o.g. Art to provide, which is freely rotatable relative to a mating connector while allowing the transmission of high currents.

Diese Aufgabe wird erfindungsgemäß durch einen Steckverbinder der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a connector of o.g. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.

Bei einem Steckverbinder der o.g. Art ist es erfindungsgemäß vorgesehen, dass die Innenleiterteile das Gehäuse an dem steckseitigen Ende in axialer Richtung überragen, wobei die Innenleiterteile derart angeordnet und ausgebildet sind, dass diese am steckseitigen Ende in dem Bereich, in dem diese das Gehäuse überragen, in axialer Richtung voneinander beabstandet die Kontaktflächen zum elektrischen Kontaktieren mit entsprechenden Leiterteilen in dem Gegenstecker ausbilden, wobei die Kontaktfläche von mindestens einem ersten Innenleiterteil als ein in Umfangsrichtung durch eine Lücke unterbrochener erster Kontaktflächenhohlzylinder ausgebildet ist, wobei der Kontaktabschnitt von mindestens einem zweiten Innenleiterteil derart ausgebildet und angeordnet ist, dass dieser durch die Lücke des ersten Kontaktflächenhohlzylinders in axialer Richtung und elektrisch isoliert von dem ersten Kontaktflächenhohlzylinder hindurch greift, so dass die Kontaktfläche des zweiten Innenleiterteils in axialer Richtung näher am steckseitigen Ende des Steckverbinders angeordnet ist, als die Kontaktfläche des ersten Innenleiterteils.In a connector of the aforementioned type, it is inventively provided that the inner conductor parts of the housing at the plug-side end in the axial direction project beyond, wherein the inner conductor parts are arranged and formed such that they at the plug-side end in the region in which they project beyond the housing, spaced from each other in the axial direction form the contact surfaces for electrical contacting with corresponding conductor parts in the mating connector, wherein the contact surface of at least a first inner conductor part is formed as a first contact surface hollow cylinder interrupted by a gap in the circumferential direction, wherein the contact portion of at least one second inner conductor part is formed and arranged such that it engages through the gap of the first contact surface hollow cylinder in the axial direction and electrically isolated from the first contact surface hollow cylinder in that the contact surface of the second inner conductor part is arranged closer to the plug-side end of the plug connector in the axial direction than the contact surface of the first inner conductor part.

Dies hat den Vorteil, dass der Steckverbinder im zusammengesteckten Zustand mit einem Gegensteckverbinder bzgl. dieses Gegensteckverbinders frei drehbar ist, so dass mechanische Spannungen in dem Steckverbinder und dem mit diesem verbundenen Kabel in gestecktem Zustand wirksam vermieden sind, und gleichzeitig hohe elektrische Ströme von beispielsweise 20 Ampere oder mehr über diesen Steckverbinder funktionssicher übertragen werden können. Zusätzlich ist eine mechanische Verriegelung des Steckverbinders im Gegensteckverbinder mit hohen Haltekräften einfach und funktionssicher über die Innenleiterteile realisierbar, da diese in axialer Richtung mechanisch belastbar von dem Isolierteil gehalten sind. Der offene Hohlzylinder der Kontaktfläche ermöglicht eine einfache Montage durch Aufstecken des Innenleiterteils in radialer Richtung auf das Isolierteil. Hierdurch ist eine automatisierte, maschinelle Fertigung der Verbindung von Steckverbinder und Kabel möglich.This has the advantage that the connector in the assembled state with a mating connector with respect. This mating connector is freely rotatable so that mechanical stresses in the connector and connected to this cable in the plugged state are effectively avoided, and at the same time high electrical currents of example 20 Amperes or more can be transmitted functionally safe over this connector. In addition, a mechanical locking of the connector in the mating connector with high holding forces is easy and reliable on the inner conductor parts feasible, since they are held mechanically strong in the axial direction of the insulating part.

For electrical and mechanical connection of the cable-side end 22 of the connector, a support sleeve 32 is provided. The two parts 16, 18 of the insulating part are designed such that they can be inserted into the housing 10 in the axial direction. The second part 18 of the insulating part has a portion with a circumferentially circumferential groove 34 and a cover 36 which projects beyond the housing 10 in the axial direction and in the direction of the plug-side end of the connector. In this groove 34, a slotted locking ring 38 can be arranged, which fixes the housing 10 at the plug-side end 20 in the axial direction.

Das erste Innenleiterteil 12 weist eine erste Kontaktfläche 40 zum elektrischen und mechanischen Kontaktieren eines entsprechenden Kontaktes in dem Gegensteckverbinder sowie einen sich von der ersten Kontaktfläche 40 in Richtung des kabelseitigen Endes 22 des Steckverbinders in axialer Richtung erstreckenden ersten Kontaktabschnitt 42 auf, welcher zum elektrischen und mechanischen verbinden mit dem ersten Leiter 28 des Kabels 24 ausgebildet ist. Das zweite Innenleiterteil 14 weist eine zweite Kontaktfläche 44 zum elektrischen und mechanischen Kontaktieren eines entsprechenden Kontaktes in dem Gegensteckverbinder sowie einen sich von der zweiten Kontaktfläche 44 in Richtung des kabelseitigen Endes 22 des Steckverbinders in axialer Richtung erstreckenden zweiten Kontaktabschnitt 46 auf, welcher zum elektrischen und mechanischen verbinden mit dem zweiten Leiter 30 des Kabels 24 ausgebildet ist.The first inner conductor part 12 has a first contact surface 40 for electrically and mechanically contacting a corresponding contact in the mating connector and a first contact section 42 extending from the first contact surface 40 in the direction of the cable-side end 22 of the connector in the axial direction, which electrical and mechanical connected to the first conductor 28 of the cable 24 is formed. The second inner conductor part 14 has a second contact surface 44 for electrically and mechanically contacting a corresponding contact in the Mating connector and extending from the second contact surface 44 in the direction of the cable-side end 22 of the connector in the axial direction extending second contact portion 46 which is formed for electrical and mechanical connection to the second conductor 30 of the cable 24.

Das erste Teil 16 des Isolierteils bildet am steckseitigen Ende 20 des Steckverbinders eine Stirnseite 48 aus.The first part 16 of the insulating part forms an end face 48 at the plug-in end 20 of the plug connector.

An einer Aussenwandung des Gehäuses 10 ist eine in Umfangsrichtung umlaufende Nut 50 ausgebildet. Diese dient ggf. als Rasteinrichtung für einen entsprechenden Verriegelungs- oder Rastmechanismus am Gegensteckverbinder, um den Steckverbinder und den Gegensteckverbinder in zusammengestecktem Zustand gegen ein unerwünschtes axiales auseinander ziehen miteinander mechanisch zu verriegeln bzw. zu verraste.On an outer wall of the housing 10, a circumferentially circumferential groove 50 is formed. This optionally serves as a latching device for a corresponding locking or locking mechanism on the mating connector to pull the connector and the mating connector in the assembled state against an undesirable axial pull apart mechanically lock or lock.

Die erste und zweite Kontaktfläche 40, 44 der Innenleiterteile 12, 14 ist jeweils als ein in Umfangsrichtung durch eine Lücke 52 bzw. 54 unterbrochener erster bzw. zweite Kontaktflächenhohlzylinder ausgebildet, so dass sich im Wesentlichen für die Kontaktflächen 40, 44 eine ringförmige Struktur mit einer offenen Seite bzw. Lücke 52, 54 ergibt. Die Hohlzylinder 40, 44 sind dabei als gerade Hohlkreiszylinder ausgebildet. Die Anordnung der Innenleiterteile 12, 14 ist dabei derart gewählt, dass der zweite Kontaktabschnitt 46 des zweiten Innenleiterteils 14 durch die Lücke 52 des ersten Innenleiterteils 12 hindurch greift. Die Anordnung ist dabei derart getroffen, dass eine gedachte Vervollständigung des ersten in Umfangsrichtung unterbrochenen Hohlzylinders 40 im Bereich der Lücke 52 zu einem vollständigen Hohlzylinder bzw. Ring den zweiten Kontaktabschnitt 46 des zweiten Innenleiterteils 14 zumindest schneidet. In der Dargestellten Ausführungsform befindet sich der zweite Kontaktabschnitt 46 des zweiten Innenleiterteils 14 auf einer Mantelfläche eines geraden Kreiszylinders, welcher von dem ersten Hohlzylinder 40 des ersten Innenleiterteils 12 aufgespannt wird. Die Durchführung des zweiten Kontaktabschnitts 46 des zweiten Innenleiterteils 14 durch die Lücke 52 des ersten Kontaktflächenhohlzylinder 40 des ersten Innenleiterteils 12 ist dabei derart, dass eine elektrische Kontaktierung zwischen diesen beiden Bauteilen vermieden ist. Durch einen entsprechenden Abstand zwischen dem zweiten Kontaktabschnitts 46 des zweiten Innenleiterteils 14 und dem ersten Kontaktflächenhohlzylinder 40 des ersten Innenleiterteils 12 auch im Bereich der Lücke 52 bleiben erstes und zweites Innenleiterteil 12, 14 elektrisch voneinander isoliert.The first and second contact surfaces 40, 44 of the inner conductor parts 12, 14 are each formed as a circumferentially interrupted by a gap 52 and 54 first and second contact surface hollow cylinder, so that substantially for the contact surfaces 40, 44 an annular structure with a open side or gap 52, 54 results. The hollow cylinder 40, 44 are formed as a straight hollow cylinder. The arrangement of the inner conductor parts 12, 14 is selected such that the second contact portion 46 of the second inner conductor part 14 engages through the gap 52 of the first inner conductor part 12 therethrough. The arrangement is made such that an imaginary completion of the first circumferentially interrupted hollow cylinder 40 in the region of the gap 52 to a complete hollow cylinder or ring the second contact portion 46 of the second inner conductor part 14 at least intersects. In the illustrated embodiment, the second contact portion 46 of the second inner conductor part 14 is located on a lateral surface of a straight circular cylinder, which is spanned by the first hollow cylinder 40 of the first inner conductor part 12. The passage of the second contact portion 46 of the second inner conductor part 14 through the gap 52 of the first contact surface hollow cylinder 40 of the first inner conductor part 12 is such that an electrical contact between these two components is avoided. By a corresponding distance between the second contact portion 46th of the second inner conductor part 14 and the first contact surface hollow cylinder 40 of the first inner conductor part 12 also in the region of the gap 52 remain first and second inner conductor part 12, 14 electrically insulated from each other.

Das erste Teil 16 des Isolierteils weist entsprechende Aufnahmen für die Kontaktflächenhohlzylinder 40, 44 der Innenleiterteile 12, 14 auf. Durch die jeweilige Lücke bzw. offene Seite 52, 54 der Kontaktflächenhohlzylinder 40, 44 der Innenleiterteile 12, 14 können diese einfach radial von außen auf das erste Teil 16 des Isolierteils aufgeschoben bzw. aufgesteckt werden. Durch eine entsprechende federelastische Ausbildung der Innenleiterteile 12, 14, werden die Kontaktflächenhohlzylinder 40, 44 beim radialen Aufstecken auf das erste Teil 16 des Isolierteils etwas radial aufgeweitet und rasten auf dem ersten Teil 16 des Isolierteils ein, indem diese unter einer federelastischen Kraft zurück in ihre Grundstellung schnappen. Die Kontaktflächen bzw. die Kontaktflächenhohlzylinder 40, 44 sind in axialer Richtung voneinander beabstandet auf dem ersten Teil 16 des Isolierteils angeordnet. Dieser Abschnitt des ersten Teil 16 des Isolierteils mit den Kontaktflächen 40, 44 überragt das Gehäuse 10 in axialer Richtung, wie aus Fig. 1 ersichtlich, so dass diese Kontaktflächen 40, 44 am steckseitigen Ende 20 des Steckverbinders zum elektrischen und mechanischen Kontaktieren von entsprechenden Kontakten im Gegensteckverbinder frei liegen. Durch die sich ergebende Geometrie am steckseitigen Ende 20 ist der Steckverbinder in einem in den Gegenstecker eingesteckten Zustand frei bzgl. des Gegensteckverbinders drehbar. Hierbei kontaktiert beispielsweise ein Kontakt im Gegensteckverbinder die erste Kontaktfläche 40 radial von außen. Damit dieser Kontakt im Gegensteckverbinder nicht auch gleichzeitig den zweiten Innenleiter 14 im Bereich der Durchführung des Kontaktabschnittes 46 durch die Lücke 52 kontaktiert, ist die Abdeckung 36 vorgesehen, die diesen Abschnitt des Kontaktabschnittes 46 im Bereich der Lücke 52 radial nach außen elektrisch isoliert. Auf diese Weise kann der entsprechende Kontakt im Gegensteckverbinder für die erste Kontaktfläche 40 in Umfangsrichtung vollständig umlaufend ausgebildet sein, ohne dass dabei in unerwünschter Weise auch der zweite Innenleiter 14 elektrisch und mechanisch von diesem Kontakt im Gegensteckverbinder kontaktiert wird.The first part 16 of the insulating part has corresponding receptacles for the contact surface hollow cylinder 40, 44 of the inner conductor parts 12, 14. Through the respective gap or open side 52, 54 of the contact surface hollow cylinder 40, 44 of the inner conductor parts 12, 14, these can simply be pushed or plugged radially from the outside onto the first part 16 of the insulating part. By a corresponding resilient design of the inner conductor parts 12, 14, the contact surface hollow cylinder 40, 44 are slightly radially expanded during radial attachment to the first part 16 of the insulating part and engage on the first part 16 of the insulating part by these under a resilient force back into their Grab basic position. The contact surfaces or the contact surface hollow cylinders 40, 44 are arranged spaced apart in the axial direction on the first part 16 of the insulating part. This portion of the first part 16 of the insulating part with the contact surfaces 40, 44 projects beyond the housing 10 in the axial direction, as seen from Fig. 1 can be seen, so that these contact surfaces 40, 44 are exposed at the plug-side end 20 of the connector for electrical and mechanical contacting of corresponding contacts in the mating connector. Due to the resulting geometry at the plug-in end 20 of the connector in a plugged into the mating connector state is free with regard to. The mating connector rotatable. Here, for example, contacted a contact in the mating connector, the first contact surface 40 radially from the outside. So that this contact in the mating connector does not simultaneously contact the second inner conductor 14 in the region of the passage of the contact section 46 through the gap 52, the cover 36 is provided which electrically insulates this section of the contact section 46 radially outward in the region of the gap 52. In this way, the corresponding contact in the mating connector for the first contact surface 40 in the circumferential direction may be formed completely circumferentially without undesirably also the second inner conductor 14 is electrically and mechanically contacted by this contact in the mating connector.

Zur Montage des Steckverbinders mit dem kabelseitigen Ende 22 an dem Kabel 24 wird dieses Abisoliert, so dass das Außenleitergeflecht 26 sowie die Leiter 28, 30 freigelegt sind. Die Stützhülse 32 wird über das Kabel 24 geschoben und das Außenleitergeflecht 26 wird darüber gelegt. Die Stützhülse 32 wird ggf. auf das Kabel 24 aufgecrimpt. Die Innenleiterteile 12, 14 werden jeweils mit einer der Leitungen 28, 30 elektrisch und mechanisch beispielsweise mittels Löten oder Schweißen verbunden. Diese so mit den Leitungen 28, 30 verbundenen Innenleiterteile 12, 14 werden radial von außen auf das erste Teil 16 des Isolierteils aufgesteckt bzw. aufgeclipst. Entsprechende Aufnahmen des ersten Teils 16 des Isolierteils für die Kontaktflächen 40, 44 isolieren diese elektrisch in axialer Richtung gegeneinander. Anschließen wird das zweite Teil 18 des Isolierteils axial auf das erste Teil 16 des Isolierteils aufgeschoben. Hierdurch ist der freie Bereich des zweiten Kontaktabschnittes 46 in der Lücke 52 radial nach außen durch die Abdeckung 36 elektrisch isoliert. Gleichzeitig fixiert das zweite Teil 18 des Isolierteils die Innenleiterteile 12, 14 in radialer Richtung und schafft eine elektrische Isolierung der Innenleiterteile 12, 14 radial nach außen gegen das später noch anzubringende Gehäuse 10. Ein entsprechender Rastmechanismus fixiert das zweite Teil 18 des Isolierteils an dem ersten Teil 16 des Isolierteils in axialer Richtung. Nun wird das Gehäuse 10 axial über das zweite Teil 18 des Isolierteils aufgeschoben, bis es an der Stützhülse 32 anschlägt. Über die Stützhülse 32 ist das Gehäuse 10, welches ebenso wie die Stützhülse 32 aus einem elektrisch leitenden Werkstoff hergestellt ist, mit dem Außenleitegeflecht 26 des Kabels 24 elektrisch und mechanisch verbunden. Der Sicherungsring 38 wird in der Nut 34 angeordnet, so dass das Gehäuse 10 axial fixiert und gegen ein Abziehen in Richtung des steckseitigen Endes gesichert ist. Hiermit ist der erfindungsgemäße Steckverbinder vollständig montiert und mit dem Kabel 24 elektrisch und mechanisch verbunden.To mount the connector with the cable-side end 22 to the cable 24, this is stripped, so that the outer conductor mesh 26 and the conductors 28, 30 are exposed. The support sleeve 32 is pushed over the cable 24 and the outer conductor braid 26 is placed over it. The support sleeve 32 is possibly crimped onto the cable 24. The inner conductor parts 12, 14 are each connected to one of the lines 28, 30 electrically and mechanically, for example by means of soldering or welding. These so connected to the lines 28, 30 inner conductor parts 12, 14 are radially plugged or clipped onto the first part 16 of the insulating part from the outside. Corresponding recordings of the first part 16 of the insulating part for the contact surfaces 40, 44 electrically insulate them against each other in the axial direction. Subsequently, the second part 18 of the insulating part is pushed axially onto the first part 16 of the insulating part. As a result, the free area of the second contact portion 46 is electrically isolated in the gap 52 radially outwardly through the cover 36. At the same time, the second part 18 of the insulating part fixes the inner conductor parts 12, 14 in the radial direction and provides an electrical insulation of the inner conductor parts 12, 14 radially outward against the later still to be attached housing 10. A corresponding locking mechanism fixes the second part 18 of the insulating part to the first Part 16 of the insulating part in the axial direction. Now, the housing 10 is pushed axially over the second part 18 of the insulating part until it abuts against the support sleeve 32. About the support sleeve 32, the housing 10, which is made as well as the support sleeve 32 made of an electrically conductive material, electrically and mechanically connected to the outer braid 26 of the cable 24. The securing ring 38 is arranged in the groove 34, so that the housing 10 is fixed axially and secured against removal in the direction of the plug-side end. Hereby, the connector according to the invention is fully assembled and connected to the cable 24 electrically and mechanically.
