Description

Steckverbinder mit Außenleiterschirm  Connector with outer conductor shield
Die vorliegende Erfindung betrifft Steckverbinder mit mindestens einem Innenleiterteil, welches zum elektrischen und mechanischen Verbinden mit einem Innenleiter eines Kabels, insbesondere eines HF-Kabels oder eines Stromkabels, ausgebildet ist, einem Außenleiterteil, welches zum elektrischen und mechanischem Verbinden mit einem Außenleiter des Kabels ausgebildet ist und eine elektromagnetische Abschirmung des Steckverbinders ausbildet, und einem Isolierteil, welches mindestens eine axiale Durchgangsbohrung zur Aufnahme mindestens eines Innenleiterteiles zum Halten des Innenleiterteils an einer vorbestimmten Position relativ zum Außenleiterteil aufweist, gemäß dem Oberbegriff des Anspruchs 1. The present invention relates to connectors having at least one inner conductor part, which is designed for electrical and mechanical connection to an inner conductor of a cable, in particular an RF cable or a power cable, an outer conductor part, which is designed for electrical and mechanical connection to an outer conductor of the cable and an electromagnetic shield of the connector is formed, and an insulating member having at least one axial through hole for receiving at least one inner conductor part for holding the inner conductor part at a predetermined position relative to the outer conductor part, according to the preamble of claim 1.
Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der o.g. Art hinsichtlich der Montage, Funktionssicherheit und Anwendungsspektrum zu verbessern. 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. The invention has for its object to improve a connector of the type mentioned above in terms of assembly, reliability and range of applications. This object is achieved by a connector of the type mentioned above 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 mindestens ein Innenleiterteil am seinem Außenumfang eine Nut aufweist, wobei das Isolierteil mindestens eine radiale Durchbrechung aufweist, durch die ein Rastmittel in radialer Richtung in mindestes eine der axialen Durchgangsbohrungen für ein Innenleiterteil hinein greift, wobei das Rastmittel derart ausgebildet und angeordnet ist, dass das Rastmittel radial federelastisch ausgelenkt ist, wenn ein Innenleiterteil in der axialen Durchgangsbohrung derart angeordnet ist, dass sich die Nut in axialer Richtung beabstandet von der radialen Durchbrechung des Isolierteils befindet, und dass das Rastmittel in die Nut des Innenleiterteils eingreift, wenn das Innenleiterteil in der axialen Durchgangsbohrung derart angeordnet ist, dass sich die Nut am Außenumfang des Innenleiterteils im Bereich der radialen Durchbrechung des Isolierteils befindet. In a connector of o.g. It is inventively provided that at least one inner conductor part has at its outer periphery a groove, wherein the insulating part has at least one radial opening, engages by a locking means in the radial direction in at least one of the axial through holes for an inner conductor part, wherein the locking means is formed and arranged that the latching means is deflected radially resiliently when an inner conductor part is arranged in the axial through hole such that the groove is spaced from the radial opening of the insulating part in the axial direction, and that the latching means engages in the groove of the inner conductor part, when the inner conductor part is arranged in the axial through hole such that the groove is located on the outer circumference of the inner conductor part in the region of the radial opening of the insulating part.
Dies hat den Vorteil, dass die Kabelhaltekräfte über den Innenleiter abgefangen werden, so dass hohe Haltekräfte dargestellt werden können. Gleichzeitig ist der Steckverbinder einfach zu montieren, da mit der Montage des Innenleiters gleichzeitig eine Zugentlastung eingerichtet ist. Hohe Haltekräfte der Zugentlastung bei gleichzeitig einfacher und funktionssicherer Montierbarkeit ermöglichen eine vielfältige Anwendungsmöglichkeit des Steckverbinders auch für Serienfertigungen von Vorrichtungen mit vielen Steckverbindungen, bei denen eine hohe mechanische Belastung des Steckverbinders bereits bei der Montage zu erwarten ist, wie beispielsweise bei Kraftfahrzeuge, in denen Kabelbäume mit kleinen Biegeradien nahe von Steckverbindungen verbaut werden. This has the advantage that the cable holding forces are intercepted via the inner conductor, so that high holding forces can be displayed. At the same time the connector is easy to assemble, as with the installation of the inner conductor at the same time a strain relief is set up. High holding forces of the strain relief at the same time simple and reliable assembly allow a variety of applications of the connector for mass production of devices with many connectors in which a high mechanical load of the connector is already expected during assembly, such as in motor vehicles in which harnesses with small bending radii are installed near plug connections.
Dadurch, dass das Rastmittel radial über einen Außenumfang des Isolierteils hinaus ragt, wenn ein Innenleiterteil in der axialen Durchgangsbohrung derart angeordnet ist, dass sich die Nut in axialer Richtung beabstandet von der Durchbrechung des Isolierteils befindet, und dass das Rastmittel einen Durchmesser aufweist, welcher kleiner oder gleich dem Außendurchmesser des Isolierteils ist, wenn das Innenleiterteil in der axialen Durchgangsbohrung derart angeordnet ist, dass sich die Nut am Außenumfang des Innenleiterteils im Bereich der radialen Durchbrechung des Isolierteils befindet, ist gleichzeitig sichergestellt, dass das Innenleiterteil richtig innerhalb des Dielektrikums positioniert ist, da ansonsten durch den radialen Überstand das Dielektrikum nicht in ein Außenleiterteil axial einschiebbar ist. Der radiale Überstand vermittelt auch optisch eine Fehlstellung des Innenleiterteils innerhalb des Isolierteiles, so dass eine fehlerhafte Montage sofort ersichtlich ist und korrigiert werden kann. Der Verbau eines fehlerhaft montierten Steckverbinders ist wirksam vermieden. Characterized in that the latching means projects radially beyond an outer circumference of the insulating part, when an inner conductor part in the axial through hole is arranged such that the groove is spaced from the opening of the insulating part in the axial direction, and that the locking means has a diameter which is smaller or equal to the outer diameter of the insulating part, when the inner conductor part is arranged in the axial through hole such that the Groove is located on the outer circumference of the inner conductor part in the region of the radial opening of the insulating part, it is ensured at the same time that the inner conductor part is properly positioned within the dielectric, otherwise the dielectric is not inserted axially into an outer conductor part by the radial supernatant. The radial projection also gives a visually misalignment of the inner conductor part within the insulating part, so that a faulty mounting is immediately apparent and can be corrected. The installation of a faulty mounted connector is effectively avoided.
Eine von der Orientierung in Umfangsrichtung unabhängige Verrastung des Innenleiterteils erzielt man dadurch, dass die Nut an mindestens einem Innenleiterteil radial umlaufend ausgebildet ist. One of the orientation in the circumferential direction independent latching of the inner conductor part is achieved by the fact that the groove is formed on at least one inner conductor part radially encircling.
Eine besonders funktionssichere Verrastung erzielt man dadurch, dass das Rastmittel als Federring, insbesondere Federringsegment, ausgebildet ist und eine der Anzahl der Durchbrechungen im Isolierteil entsprechende Anzahl von Rastnasen derart aufweist, dass bei einer vorbestimmten Position des Rastmittels relativ zum Isolierteil alle Rastnasen in jeweils eine der Durchbrechungen greifen. A particularly functionally reliable locking is achieved in that the locking means as a spring ring, in particular spring ring segment is formed and one of the number of openings in the insulating corresponding number of locking lugs such that at a predetermined position of the locking means relative to the insulating all latches in each one of Breakthroughs grab.
Eine besonders gute Ableitung von auf das Kabel wirkenden Zugkräften in axialer Richtung über das Isolierteil erzielt man dadurch, dass das Isolierteil eine radial umlaufende Nut aufweist, in der das Rastmittel angeordnet ist. A particularly good derivation of tensile forces acting on the cable in the axial direction over the insulating part is achieved in that the insulating part has a radially encircling groove in which the latching means is arranged.
Eine gleichzeitig für eine Stromübertragung und Signalübertragung über die Innenleiterteile besonders geeigneten Steckverbinder erzielt man dadurch, das Isolierteil drei axiale Durchgangsbohrungen aufweist, wobei jeweilige Längsachsen der Durchgangsbohrungen parallel zueinander ausgerichtet sind und in einer Ebene senkrecht zu den Längsachsen an den Ecken eines gleichseitigen Dreiecks angeordnet sind. A connector, which is particularly suitable for current transmission and signal transmission via the inner conductor parts, is achieved by the insulating part having three axial through-holes, wherein respective longitudinal axes of the through-holes are aligned parallel to one another and arranged in a plane perpendicular to the longitudinal axes at the corners of an equilateral triangle.
Eine besonders gute elektromagnetische Abschirmung des Steckverbinders nach außen sowie eine besonders symmetrische Verteilung von elektrischen, magnetischen und elektromagnetischen Feldern innerhalb des Steckverbinders mit entsprechend hochwertigen Eigenschaften hinsichtlich von Hochfrequenzanwendungen erzielt man dadurch, dass das Isolierteil innerhalb des Außenleiterteils derart angeordnet ist, dass ein Mittelpunkt des gleichseitigen Dreiecks auf einer zu den Längsachsen parallelen Geraden liegt, welche koaxial zum Außenleiterteil verläuft. Der Ausdruck "Mittelpunkt" bezeichnet hierbei einen Punkt in einer Ebene und innerhalb des gleichseitigen Dreiecks, welcher von allen Ecken des Dreiecks eine identische Entfernung aufweist. A particularly good electromagnetic shielding of the connector to the outside and a particularly symmetrical distribution of electrical, magnetic and electromagnetic fields within the connector with correspondingly high quality properties in terms of High-frequency applications are achieved in that the insulating part is arranged within the outer conductor part such that a center of the equilateral triangle lies on a straight line parallel to the longitudinal axes, which runs coaxially to the outer conductor part. The term "center point" refers to a point in a plane and within the equilateral triangle, which has an identical distance from all corners of the triangle.
Eine selbsttätige Auslenkung des Rastmittels durch einfaches axiales Einschieben eines Innenleiterteils in eine axiale Durchgangsbohrung des Isolierteils erzielt man dadurch, dass mindestens ein Innenleiterteil an mindestens einem axialen Ende sich konisch verjüngend derart ausgebildet ist, dass ein Außendurchmesser des Innenleiterteils an diesem axialen Ende kleiner ist als ein doppelter Abstand zwischen einer Mittellängsachse der axialen Durchgangsbohrung und einem radial inneren Ende des in die Durchgangsbohrung eingreifenden Rastmittels. Hierdurch kann das Innenleiterteil auf einfache Weise in axialer Richtung in die axiale Durchgangsbohrung des Isolierteils bis zum Einrasten des Rastmittels in die Nut des Innenleiterteils eingeschoben werden. An automatic deflection of the latching means by simply axially inserting an inner conductor part into an axial through bore of the insulating part is achieved in that at least one inner conductor part is conically tapered at at least one axial end such that an outer diameter of the inner conductor part at this axial end is smaller than a double distance between a central longitudinal axis of the axial through-hole and a radially inner end of engaging in the through-hole locking means. In this way, the inner conductor part can be inserted in a simple manner in the axial direction in the axial through hole of the insulating part until the latching of the locking means in the groove of the inner conductor part.
Eine besonders sichere Verrastung zwischen Innenleiterteil und Rastmittel erzielt man dadurch, dass ein Außendurchmesser mindestens eines Innenleiterteils im Bereich benachbart zur Nut größer ausgebildet ist als ein Abstand zwischen einem radial inneren Ende des in die Durchgangsbohrung eingreifenden Rastmittels und einer Wandung der axialen Durchgangsbohrung gegenüber der Durchbrechung in dem Isolierteil. A particularly secure latching between inner conductor part and latching means is achieved in that an outer diameter of at least one inner conductor part in the region adjacent to the groove is formed larger than a distance between a radially inner end of engaging in the through-hole locking means and a wall of the axial through hole opposite the opening in the insulating part.

Die in der Fig. 1 dargestellte, bevorzugte Ausführungsform eines erfindungsgemäßen Steckverbinders umfasst drei Innenleiterteile 10, ein Isolierteil 12, ein Außenleiterteil 14 und ein Gehäuse 16. Das Isolierteil 12 ist radial innerhalb des Außenleiterteils 14 angeordnet. Das Außenleiterteil 14 ist radial innerhalb des Gehäuses 16 angeordnet. Die Innenleiterteile 10 sind in axialen Durchgangsbohrungen 18 des Isolierteiles 12 angeordnet. Auf diese Weise ergibt sich ein koaxialer Aufbau des Steckverbinders hinsichtlich des Isolierteils 12, des Außenleiterteils 14 und des Gehäuses 16. Der erfindungsgemäße Steckverbinder dient zum mechanischen und elektrischen Verbinden mit einem Kabel 20, welches eine der Anzahl der Innenleiterteile 10 entsprechende Anzahl von Innenleitern (nicht dargestellt) und einen Außenleiter (nicht dargestellt) aufweist. Hierbei sind die Innenleiterteile 10 des Steckverbinders jeweils mit einem Innenleiter des Kabels 20 elektrisch und mechanisch verbunden. Weiterhin ist das Außenleiterteil 14 des Steckverbinders mit dem Außenleiter des Kabels 20 elektrisch und mechanisch verbunden. Der erfindungsgemäße Aufbau von Innenleiterteilen 10 und Isolierteil 12 ist aus den Fig. 2 bis 7 ersichtlich. Das Isolierteil 12 weist drei radiale Durchbrechungen 22 auf, die derart ausgebildet und angeordnet sind, dass jeweils eine Durchbrechung 22 einer axialen Durchgangsbohrung 18 zugeordnet ist. Mit anderen Worten stellt jede radiale Durchbrechung 22 jeweils eine Verbindung von einer axialen Durchgangsbohrung 18 zum Außenumfang des Isolierteils 12 her. Die Innenleiterteile 10 weisen jeweils eine radial umlaufende Nut 24 auf, welche derart angeordnet und ausgebildet ist, dass in einer gewünschten, vorbestimmten Position eines jeweiligen Innenleiterteils 10 innerhalb der axialen Durchgangsbohrung 18 des Isolierteils 12 die jeweilige Nut 24 im Bereich der dieser axialen Durchgangsbohrung 18 zugeordneten radialen Durchbrechung 22 angeordnet ist. Mit anderen Worten fluchten die Nut 24 und die radiale Durchbrechung 22 bzw. die Nut 24 ist radial von außen durch die radiale Durchbrechung 22 zugänglich, wenn sich das Innenleiterteil 10 an einer gewünschten, vorbestimmten axialen Position in der axialen Durchgangsbohrung 18 befindet. Dies dient zum axialen Fixieren der Innenleiterteile 10 in den axialen Durchgangsbohrungen 18 des Isolierteils 12, wie nachfolgend näher erläutert wird. The preferred embodiment of a connector according to the invention shown in FIG. 1 comprises three inner conductor parts 10, an insulating part 12, an outer conductor part 14 and a housing 16. The insulating part 12 is arranged radially inside the outer conductor part 14. The outer conductor part 14 is arranged radially inside the housing 16. The inner conductor parts 10 are arranged in axial through holes 18 of the insulating member 12. In this way, a coaxial structure of the connector with respect to the insulating part 12, the outer conductor part 14 and the housing 16. The connector according to the invention is used for mechanical and electrical connection to a cable 20, which corresponds to the number of inner conductor parts 10 corresponding number of inner conductors (not shown) and an outer conductor (not shown). Here, the inner conductor parts 10 of the connector are each electrically and mechanically connected to an inner conductor of the cable 20. Furthermore, the outer conductor part 14 of the connector with the outer conductor of the cable 20 is electrically and mechanically connected. The construction according to the invention of inner conductor parts 10 and insulating part 12 can be seen in FIGS. 2 to 7. The insulating member 12 has three radial openings 22, which are formed and arranged such that in each case an opening 22 is associated with an axial through hole 18. In other words, each radial opening 22 in each case establishes a connection from an axial through-bore 18 to the outer circumference of the insulating part 12. The inner conductor parts 10 each have a radially encircling groove 24, which is arranged and designed such that in a desired, predetermined position of a respective inner conductor part 10 within the axial through hole 18 of the insulating member 12, the respective groove 24 in the region of this axial through hole 18 assigned radial aperture 22 is arranged. In other words, the groove 24 and the radial opening 22 and the groove 24 are radially accessible from the outside through the radial opening 22, when the inner conductor part 10 is located at a desired, predetermined axial position in the axial through hole 18. This serves for the axial fixing of the inner conductor parts 10 in the axial through-holes 18 of the insulating part 12, as will be explained in more detail below.
Es ist ein Rastmittel in Form eines Federringes 26 vorgesehen. Dieser Federring 26 ist an einer Stelle unterbrochen bzw. als Ringsegment ausgebildet und aus einem federelastischen Werkstoff hergestellt. Auf diese Weise kann der Federring 26 aus einer Grundposition heraus radial aufgeweitet werden. An dem Außenumfang der Isolierteils 12 ist im Bereich der radialen Durchbrechungen 22 eine Nut 28 derart ausgebildet, dass der Federring 26 in dieser Nut 28 anordnbar ist bzw. in diese Nut 28 passt, wobei in der Grundposition des Federringes 26 der Außenumfang des Federringes 26 nicht über einen Außenumfang des Isolierteils 12 hinaus ragt. Der Federring 26 weist drei Rastnasen 30 auf, welche derart ausgebildet und angeordnet sind, dass bei in der Nut 28 des Isolierteils 12 angeordnetem Federring 26 in dessen Grundposition jeweils eine Rastnase 30 durch eine radiale Durchbrechung 22 greift und in die jeweilige axiale Durchgangsbohrung 18 radial hinein ragt. Auf diese Weise ist ein Teil der lichten Weite bzw. des Innenumfangs der jeweiligen axialen Durchgangsbohrung 18 durch einen Teil einer Rastnase 30 im Bereich der jeweiligen radialen Durchbrechung 22 versperrt. Die Innenleiterteile 10 weisen an einem axialen Ende 32 eine konische Verjüngung 34 auf. Diese konische Verjüngung 34 ist derart ausgebildet, dass beim axialen Einschieben der Innenleiterteile 10 in die jeweiligen axialen Durchgangsbohrungen 18 die Rastnasen 30 des Federringes 26 von den Innenleiterteilen 10 radial nach außen gedrückt werden und damit der Federring 26 radial aufgeweitet wird. Mit anderen Worten wird der Federring 26 aus seiner Grundposition in eine radial aufgeweitete Position aufgebogen. Der Federring 26 und die Rastnasen 30 sind dabei derart ausgebildet, dass ein Außenumfang des Federringes 26 zumindest teilweise über den Außenumfang des Isolierteils 12 in radialer Richtung nach außen hinaus ragt, wenn die Rastnasen 30 auf der Außenfläche der Innenleiterteile 10 beabstandet von der Nut 24 und beabstandet von der konischen Verjüngung 34 aufliegen. Gleichzeitig ist ein Innendurchmesser des Außenleiterteils 14 derart ausgebildet, dass ein axiales Einschieben des Isolierteils 12 in das Außenleiterteil 14 mechanisch blockiert ist, solange der Federring 26 auch nur teilweise über den Außenumfang des Isolierteils 12 radial hinaus ragt. Hierdurch ist eine Montage des Steckverbinders solange verhindert, solange nicht alle Innenleiterteile 10 an einer gewünschten, vorbestimmten Position in der axialen Durchgangsbohrung 18 des Isolierteils 12 angeordnet sind. Dieser Zustand einer unvollständigen Montage der Innenleiterteile 10 ist auch optisch durch den radial aufgeweiteten Federring 26 erkennbar und sichtbar. Sobald ein jeweiliges Innenleiterteil 10 in der axialen, gewünschten Position angekommen ist, kommen die Nut 24 des Innenleiterteils 10 und die radiale Durchbrechung 22 des Isolierteils in Deckung miteinander und die jeweilige Rastnase 30 des Federringes 26 schnappt in die Nut 24 ein. Sobald alle Rastnasen 30 in jeweilige Nuten 24 eingeschnappt sind, ist der Federring 26 in seine Grundposition zurückgekehrt und überragt das Isolierteil 12 nicht mehr radial nach außen. Dieser Zustand ist aus den Fig. 4 bis 7 ersichtlich. It is a locking means in the form of a spring ring 26 is provided. This spring ring 26 is interrupted at one point or formed as a ring segment and made of a resilient material. In this way, the spring ring 26 can be radially expanded from a basic position out. On the outer circumference of the insulating part 12, a groove 28 is formed in the region of the radial openings 22 such that the spring ring 26 can be arranged in this groove 28 or fits into this groove 28, wherein in the basic position of the spring ring 26, the outer circumference of the spring ring 26 not protrudes beyond an outer periphery of the insulating part 12 also. The spring ring 26 has three locking lugs 30, which are designed and arranged such that in the groove 28 of the insulating 12 arranged spring ring 26 in its basic position in each case a detent 30 engages through a radial opening 22 and radially into the respective axial through hole 18 protrudes. In this way, part of the clear width or the inner circumference of the respective axial through-bore 18 is blocked by a part of a latching lug 30 in the region of the respective radial opening 22. The inner conductor parts 10 have a conical taper 34 at an axial end 32. This conical taper 34 is formed such that the axial insertion of the inner conductor parts 10 in the respective axial through holes 18, the locking lugs 30 of the spring ring 26 are pressed radially outwardly from the inner conductor parts 10 and thus the spring ring 26 is radially expanded. In other words, the spring ring 26 is bent from its basic position to a radially expanded position. The spring ring 26 and the locking lugs 30 are formed such that an outer periphery of the spring ring 26 at least partially beyond the outer periphery of the insulating member 12 in the radial direction outwardly protrudes when the locking lugs 30 on the outer surface of the inner conductor parts 10 spaced from the groove 24 and spaced from the conical taper 34 rest. At the same time an inner diameter of the outer conductor part 14 is formed such that an axial insertion of the insulating member 12 is mechanically blocked in the outer conductor part 14, as long as the spring ring 26 projects only partially beyond the outer periphery of the insulating member 12 radially. As a result, assembly of the connector is prevented as long as not all inner conductor parts 10 are arranged at a desired, predetermined position in the axial through hole 18 of the insulating member 12. This state of incomplete assembly of the inner conductor parts 10 is also visually recognizable and visible by the radially expanded spring ring 26. As soon as a respective inner conductor part 10 has arrived in the axial, desired position, the groove 24 of the inner conductor part 10 and the radial opening 22 of the insulating part come into coincidence with each other and the respective latching lug 30 of the spring ring 26 snaps into the groove 24. Once all locking lugs 30 are snapped into respective grooves 24, the spring ring 26 has returned to its basic position and no longer projects beyond the insulating member 12 radially outward. This state is apparent from FIGS. 4 to 7.
Die Nuten 24 und Rastnasen 30 sind derart ausgebildet, dass eine erneute radiale Aufweitung des Federringes 26 allein durch eine axiale Krafteinwirkung auf die Innenleiterteile 10 nicht möglich ist. Auf diese Weise sind die Innenleiterteile 10 axial in den Durchgangsbohrungen 18 fixiert und es wird eine auf das Kabel 20 wirkende Zugkraft über die Innenleiterteile 10, den Federring 26 und das Isolierteil 12 auf den Steckverbinder übertragen und von diesem abgefangen, ohne das Kabel 20 oder die elektrischen Verbindungen zwischen dem Außenleiter des Kabels 20 und dem Außenleiterteil 14 sowie den Innenleiterteilen 10 und den Innenleitern des Kabels 20 zu beschädigen bzw. deren elektrische Eigenschaften zu beeinflussen. Die Zugentlastung erfolgt somit über die Innenleiterteile 10, die große Kräfte aufnehmen und übertragen können ohne dabei selbst mechanischen Schaden zu nehmen. Diese Zugentlastung mittels des bzw. der Innenleiter des Kabels 20 ist besonders bei großen Querschnitten der Innenleiter des Kabels 20 von beispielsweise 16 mm2 bis 120 mm2 vorteilhaft. Durch diese Ausbildung der Zugentlastung über die Innenleiterteile 10 ist mit der Montage der Innenleiterteile 10 in dem Isolierteil 12 mit dem Einrasten der Rastnasen 30 gleichzeitig die Zugentlastung hergestellt, ohne dass es hierfür zusätzlicher Montageschritte bedarf. Die Montage des Steckverbinders an einem Kabelende ist somit vereinfacht. The grooves 24 and locking lugs 30 are formed such that a renewed radial expansion of the spring ring 26 is not possible solely by an axial force on the inner conductor parts 10. In this way, the inner conductor parts 10 are axially fixed in the through holes 18 and it is transmitted to the cable 20 pulling force on the inner conductor parts 10, the spring ring 26 and the insulating member 12 on the connector and intercepted by this, without the cable 20 or electrical connections between the outer conductor of the cable 20 and the outer conductor part 14 and the inner conductor parts 10 and the inner conductors of the cable 20 to damage or affect their electrical properties. The strain relief thus takes place via the inner conductor parts 10, which can absorb and transmit large forces without taking mechanical damage itself. This strain relief by means of the or the inner conductor of the cable 20 is particularly advantageous for large cross sections of the inner conductor of the cable 20, for example 16 mm 2 to 120 mm 2 . Due to this design of the strain relief via the inner conductor parts 10, the strain relief is simultaneously produced with the assembly of the inner conductor parts 10 in the insulating part 12 with the engagement of the latching lugs 30, without the need for additional assembly steps. The mounting of the connector to a cable end is thus simplified.
Voranstehend ist die Erfindung anhand eines Steckverbinders mit drei Innenleiterteilen 10 dargestellt. Dies ist jedoch lediglich beispielhaft. Der Steckverbinder kann ebenfalls ein, zwei, vier oder mehr Innenleiterteile 10 aufweisen, je nach der Anzahl der Innenleiter des Kabels 20. The invention has been described above with reference to a connector with three inner conductor parts 10. However, this is just an example. The connector may also have one, two, four or more inner conductor parts 10, depending on the number of inner conductors of the cable 20.
