Definitions

  • the invention relates to a connector arrangement for releasably connecting electrically conductive cables, in particular high-frequency cables, to an electrical component.
  • high-frequency cables such as coaxial cables are used. Due to the coaxial arrangement of the inner conductor, dielectric and shielding, a high transmission quality of signals with low attenuation and low susceptibility to interference can be ensured as far as possible, provided that the coaxial structure and the associated line impedance remain largely constant over the entire length of the electrical line.
  • the cable ends are often problematic, to which connection systems are usually attached in order to connect the cable with the components or other cables between which the data transmission is to take place in an electrically conductive and communicative manner.
  • connection systems which can be designed as a plug-in coupling, for example, have the disadvantage that a constant line wave resistance, in particular at the connection point, can only be achieved with great difficulty because, for example, due to tolerances Air gap remains at the connection point between the two connection partners, which can have a negative effect on the return loss and thus the transmission quality.
  • the connection system must have a geometry that minimizes the risk of damage to the often very delicate ends of the cables during the connection process or during normal operation of the cable.
  • a connector arrangement according to the invention is suitable for connecting a cable to an electrical component.

  • the insulator element of the plug-in unit is arranged within the outer conductor element of the plug-in unit.
  • the insulator element of the plug-in unit has an inner conductor channel in which the inner conductor element of the plug-in unit is arranged. Under the inner conductor channel in In this context, a tubular passage in the insulator element can be understood.
  • the mating plug-in unit has a comparable arrangement of outer conductor element, insulator element and inner conductor element.
  • the insulator element of the mating plug-in unit also has an inner conductor channel.

Most preferred, however, is a coaxial arrangement of the inner conductor element, outer conductor element and insulator element both in the plug-in unit and in the mating plug-in unit.
  • the plug-in unit has a first plug-in side.
  • the first plug-in side can be understood to mean the side of the plug-in unit on which the plug-in unit can be connected, preferably detachably, to the mating plug-in unit.

  • the mating plug-in unit has a second plug-in side.
  • the second plug-in side can be understood as the side of the mating plug-in unit to which the mating plug-in unit can be connected, preferably detachably, to which the plug-in unit can be connected.

Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Steckverbinderanordnung zum lösbaren Verbinden von elektrisch leitenden Kabeln, insbesondere Hochfrequenzkabeln, mit einem elektrischen Bauelement.The invention relates to a connector arrangement for releasably connecting electrically conductive cables, in particular high-frequency cables, to an electrical component.

Stand der TechnikState of the art

Aufgrund der zunehmenden Digitalisierung von Komponenten und Systemen und der damit verbundenen steigenden Menge an zu übertragenden Daten werden in der heutigen Zeit immer größere Anforderungen an die zur Übertragung benötigten Kabel gestellt. Insbesondere eine gleichbleibend hohe Übertragungsqualität von Signalen über große Frequenzbereiche, bei geringer oder zumindest über den betreffenden Frequenzbereich konstanter Dämpfung, spielen bei der Übertragung von großen Datenmengen eine immer zentralere Rolle.Due to the increasing digitization of components and systems and the associated increase in the amount of data to be transmitted, more and more demands are placed on the cables required for transmission these days. In particular, a consistently high transmission quality of signals over large frequency ranges, with low attenuation or at least constant attenuation over the relevant frequency range, play an increasingly central role in the transmission of large amounts of data.

Um diesen Anforderungen gerecht zu werden, kommen Hochfrequenzkabel, wie zum Beispiel Koaxialkabel zum Einsatz. Durch die koaxiale Anordnung von Innenleiter, Dielektrikum und Schirmung kann weitestgehend eine hohe Übertragungsqualität von Signalen bei geringer Dämpfung und geringer Störanfälligkeit sichergestellt werden, sofern der koaxiale Aufbau und der damit verbundene Leitungswellenwiderstand über die gesamte Länge der elektrischen Leitung weitestgehend konstant bleiben. Problematisch sind in diesem Zusammenhang jedoch häufig die Kabelenden, an denen in aller Regel Verbindungssysteme angebracht sind, um das Kabel mit den Komponenten oder weiteren Kabeln, zwischen denen die Datenübertragung erfolgen soll, elektrisch leitend und kommunizierend zu verbinden.To meet these requirements, high-frequency cables such as coaxial cables are used. Due to the coaxial arrangement of the inner conductor, dielectric and shielding, a high transmission quality of signals with low attenuation and low susceptibility to interference can be ensured as far as possible, provided that the coaxial structure and the associated line impedance remain largely constant over the entire length of the electrical line. In this context, however, the cable ends are often problematic, to which connection systems are usually attached in order to connect the cable with the components or other cables between which the data transmission is to take place in an electrically conductive and communicative manner.

Solche Verbindungssysteme, die beispielsweise als Steckkupplung ausgeführt sein können, besitzen jedoch den Nachteil, dass ein konstanter Leitungswellenwiderstand, insbesondere an der Verbindungsstelle nur sehr schwer erzielbar ist, da bspw. durch Toleranzen ein Luftspalt an der Verbindungsstelle zwischen beiden Verbindungspartnern verbleibt, der sich negativ auf die Rückflussdämpfung und damit die Übertragungsqualität auswirken kann. Gleichzeitig muss jedoch das Verbindungssystem eine Geometrie aufweisen, die das Risiko einer Beschädigung der oft sehr filigranen Enden der Kabel während des Verbindungsprozesses oder des Normalbetriebes des Kabels möglichst geringhalten.Such connection systems, which can be designed as a plug-in coupling, for example, have the disadvantage that a constant line wave resistance, in particular at the connection point, can only be achieved with great difficulty because, for example, due to tolerances Air gap remains at the connection point between the two connection partners, which can have a negative effect on the return loss and thus the transmission quality. At the same time, however, the connection system must have a geometry that minimizes the risk of damage to the often very delicate ends of the cables during the connection process or during normal operation of the cable.

Beschreibung der ErfindungDescription of the invention

Es ist daher eine Aufgabe der vorliegenden Erfindung, zumindest einen im Stand der Technik genannten Nachteil zu überwinden und eine lösbare Verbindungsanordnung zum Verbinden von Kabeln, insbesondere Hochfrequenzkabeln mit einem elektrischen Bauelement, wie beispielsweise einem weiteren Kabel oder einer Halbleiterplatine herzustellen, bei der die Übertragungsqualität der zu übertragenden Signale möglichst wenig beeinträchtigt wird.It is therefore an object of the present invention to overcome at least one disadvantage mentioned in the prior art and to produce a detachable connection arrangement for connecting cables, in particular high-frequency cables, to an electrical component, such as, for example, another cable or a semiconductor board, in which the transmission quality of the to be transmitted signals is affected as little as possible.

Die erfindungsgemäße Aufgabe wird durch eine Steckverbinderanordnung mit den Merkmalen des unabhängigen Anspruchs gelöst. Weitere vorteilhafte Ausgestaltungsformen der Erfindung lassen sich den Unteransprüchen, der Beschreibung sowie den Zeichnungen entnehmen.The object according to the invention is achieved by a connector arrangement having the features of the independent claim. Further advantageous embodiments of the invention can be found in the subclaims, the description and the drawings.

Eine erfindungsgemäße Steckverbinderanordnung ist zum Verbinden eines Kabels mit einem elektrischen Bauelement geeignet. Unter einem elektrischen Bauelement kann in diesem Zusammenhang beispielsweise eine Halbleiterplatine aber auch ein weiteres Kabel verstanden werden, das mit dem Kabel verbunden werden soll. Die erfindungsgemäße Steckverbinderanordnung umfasst eine Steckeinheit. Die Steckeinheit ist mit dem Kabel oder dem elektrischen Bauelement elektrisch leitend und bevorzugt unlösbar verbindbar und weist ein Außenleiterelement, ein Isolatorelement und ein Innenleiterelement auf. Des Weiteren umfasst die Steckverbinderanordnung eine Gegensteckeinheit, die elektrisch leitend und bevorzugt lösbar mit der Steckeinheit verbindbar ist. Die Gegensteckeinheit ist elektrisch leitend mit dem elektrischen Bauelement oder dem Kabel, bevorzugt unlösbar verbunden, das mit der Steckeinheit verbunden werden soll. Die Gegensteckeinheit umfasst ebenfalls ein Außenleiterelement, ein Isolatorelement und ein Innenleiterelement.A connector arrangement according to the invention is suitable for connecting a cable to an electrical component. In this context, an electrical component can be understood to mean, for example, a semiconductor circuit board, but also another cable that is to be connected to the cable. The connector arrangement according to the invention comprises a plug-in unit. The plug-in unit can be connected to the cable or the electrical component in an electrically conductive manner and preferably non-detachably, and has an outer conductor element, an insulator element and an inner conductor element. Furthermore, the plug-in connector arrangement comprises a mating plug-in unit which can be connected to the plug-in unit in an electrically conductive and preferably detachable manner. The mating plug-in unit is electrically conductively connected to the electrical component or the cable, preferably permanently connected, which is to be connected to the plug-in unit. The mating plug-in unit also comprises an outer conductor element, an insulator element and an inner conductor element.

Das Isolatorelement der Steckeinheit ist innerhalb des Außenleiterelements der Steckeinheit angeordnet. Das Isolatorelement der Steckeinheit weist einen Innenleiterkanal auf, in dem das Innenleiterelement der Steckeinheit angeordnet ist. Unter Innenleiterkanal kann in diesem Zusammenhang ein röhrenförmiger Durchgang im Isolatorelement verstanden werden. Die Gegensteckeinheit weist eine vergleichbare Anordnung von Außenleiterelement, Isolatorelement und Innenleiterelement auf. Das Isolatorelement der Gegensteckeinheit weist also ebenfalls einen Innenleiterkanal auf. Ein beschriebener Aufbau kann beispielsweise realisiert sein, indem das Außenleiterelement von Steckeinheit und Gegensteckeinhalt als Hülse ausgebildet ist, in der das, bevorzugt zylinderförmige, Isolatorelement angeordnet ist. Das Innenleiterelement ist im Innenleiterkanal des Isolatorelements angeordnet. Die Längsachsen von Innenleiterelement, Außenleiterelement und Isolatorelement verlaufen bevorzugt sowohl bei der Steckeinheit als auch bei der Gegensteckeinheit vorzugsweise parallel. Besonders bevorzugt ist dabei, dass sowohl bei der Steckeinheit als auch bei der Gegensteckeinheit der Innenleiterkanal, insbesondere mittig auf der Längsachse des Isolatorelements angeordnet ist. Am meisten ist jedoch eine koaxiale Anordnung von Innenleiterelement, Außenleiterelement und Isolatorelement sowohl bei der Steckeinheit als auch bei der Gegensteckeinheit bevorzugt.The insulator element of the plug-in unit is arranged within the outer conductor element of the plug-in unit. The insulator element of the plug-in unit has an inner conductor channel in which the inner conductor element of the plug-in unit is arranged. Under the inner conductor channel in In this context, a tubular passage in the insulator element can be understood. The mating plug-in unit has a comparable arrangement of outer conductor element, insulator element and inner conductor element. The insulator element of the mating plug-in unit also has an inner conductor channel. A structure described can be implemented, for example, in that the outer conductor element of the plug-in unit and the mating plug-in content is designed as a sleeve in which the, preferably cylindrical, insulator element is arranged. The inner conductor element is arranged in the inner conductor channel of the insulator element. The longitudinal axes of the inner conductor element, outer conductor element and insulator element preferably run parallel both in the plug-in unit and in the mating plug-in unit. It is particularly preferred that both the plug-in unit and the mating plug-in unit have the inner conductor channel, in particular arranged centrally on the longitudinal axis of the insulator element. Most preferred, however, is a coaxial arrangement of the inner conductor element, outer conductor element and insulator element both in the plug-in unit and in the mating plug-in unit.

Die Steckeinheit weist eine erste Steckseite auf. Unter der ersten Steckseite kann in diesem Zusammenhang die Seite der Steckeinheit verstanden werden, an der die Steckeinheit mit der Gegensteckeinheit, bevorzugt lösbar, verbindbar ist. Das Isolatorelement der Steckeinheit bildet an einem Ende, das der Steckseite zugewandt ist, zumindest teilweise ein Steckprofil aus. Das Steckprofil ist dabei besonders bevorzugt an der Stirnseite des Isolatorelements der Steckeinheit angeordnet, die der ersten Steckseite zugewandt ist. Das Steckprofil verläuft zumindest abschnittsweise um den Innenleiterkanal und weist zumindest eine Erhebung und/oder Vertiefung auf. Ebenso ist es möglich, dass das Steckprofil mehrere Erhebungen und Vertiefungen oder einer Kombination von einer oder mehreren Erhebungen und einer oder mehreren Vertiefungen aufweist. Die Erhebungen und/oder Vertiefungen erstrecken sich dabei bevorzugt parallel zur Längsachse des Isolatorelements der Steckeinheit. Das Steckprofil ist des Weiteren bevorzugt ringförmig um den Innenleiterkanal angeordnet und kann entweder im Abstand zum Innenleiterkanal angeordnet sein oder an den Innenleiterkanal angrenzen.The plug-in unit has a first plug-in side. In this context, the first plug-in side can be understood to mean the side of the plug-in unit on which the plug-in unit can be connected, preferably detachably, to the mating plug-in unit. The insulator element of the plug-in unit forms at least partially a plug-in profile at one end facing the plug-in side. The plug-in profile is particularly preferably arranged on the end face of the insulator element of the plug-in unit that faces the first plug-in side. The plug-in profile runs at least in sections around the inner conductor channel and has at least one elevation and / or depression. It is also possible for the plug-in profile to have several elevations and depressions or a combination of one or more elevations and one or more depressions. The elevations and / or depressions preferably extend parallel to the longitudinal axis of the insulator element of the plug-in unit. The plug profile is furthermore preferably arranged in a ring around the inner conductor channel and can either be arranged at a distance from the inner conductor channel or adjoin the inner conductor channel.

Die Gegensteckeinheit weist eine zweite Steckseite auf. Unter der zweiten Steckseite kann in diesem Zusammenhang die Seite der Gegensteckeinheit verstanden werden, mit der die Gegensteckeinheit, bevorzugt lösbar, mit der der Steckeinheit verbindbar ist. Das Isolatorelement der Gegensteckeinheit bildet zumindest teilweise an einem Ende, das der zweiten Steckseite zugewandt ist, ein Gegensteckprofil aus. Das Gegensteckprofil ist bevorzugt auf einer Stirnseite des Isolatorelements der Gegensteckeinheit angeordnet. Das Gegensteckprofil verläuft bevorzugt ebenfalls zumindest teilweise um den Innenleiterkanal des Isolatorelements der Gegensteckeinheit und kann ringförmig ausgebildet sein. Das Gegensteckprofil entspricht zumindest abschnittsweise einer Negativform des Steckprofils.The mating plug-in unit has a second plug-in side. In this context, the second plug-in side can be understood as the side of the mating plug-in unit to which the mating plug-in unit can be connected, preferably detachably, to which the plug-in unit can be connected. The insulator element of the mating plug-in unit at least partially forms a mating plug-in profile at one end facing the second plug-in side. The mating plug-in profile is preferably arranged on an end face of the insulator element of the mating plug-in unit. That Mating plug-in profile preferably also runs at least partially around the inner conductor channel of the insulator element of the mating plug-in unit and can be designed in an annular manner. The mating plug-in profile corresponds at least in sections to a negative shape of the plug-in profile.

Die Steckeinheit und die Gegensteckeinheit sind derart miteinander verbindbar, dass das Steckprofil und das Gegensteckprofil zumindest abschnittsweise aneinander anliegen. Die Verbindung kann dabei beispielsweise erfolgen, indem die Außenleiterelemente der Steckeinheit und Gegensteckeinheit mit einander zugewandter erster und zweiter Steckseite ineinandergeschoben werden und sich die Innenleiterelemente der Steckeinheit und der Gegensteckeinheit elektrisch leitend miteinander verbinden.The plug-in unit and the mating plug-in unit can be connected to one another in such a way that the plug-in profile and the mating plug-in profile abut one another at least in sections. The connection can be made, for example, in that the outer conductor elements of the plug-in unit and mating plug-in unit are pushed into one another with the first and second plug-in sides facing each other and the inner conductor elements of the plug-in unit and the mating plug-in unit are connected to one another in an electrically conductive manner.

Durch die erfindungsgemäße Steckverbinderanordnung wird eine Verbindungsmöglichkeit, insbesondere für Hochfrequenzkabel bereitgestellt, bei der eine vergleichsweise hohe Signalqualität sichergestellt werden kann. Dies begründet sich im Wesentlichen durch das aneinander Anliegen des Steckprofils in das Gegensteckprofils. Auch im Fall von großen Toleranzschwankungen bleibt auf diese Art sichergestellt, dass zwischen beiden Isolatorelementen kein bis zum Außenleiter durchgängiger Luftspalt entstehen kann. Schwankungen im Leitungswellenwiderstand und damit verbunden in der Signalqualität können somit auch bei Toleranzschwankungen geringgehalten werden.The connector arrangement according to the invention provides a connection option, in particular for high-frequency cables, in which a comparatively high signal quality can be ensured. This is essentially due to the fact that the plug-in profile rests against one another in the mating plug-in profile. Even in the case of large tolerance fluctuations, it is ensured in this way that no air gap that is continuous up to the outer conductor can arise between the two insulator elements. Fluctuations in the line impedance and the associated signal quality can thus be kept low even with tolerance fluctuations.

Es kann von Vorteil sein, wenn das Steckprofil teilweise durch das Innenleiterelement der Steckeinheit ausgebildet ist. Es kann also ein Teil des Steckprofils vom Isolatorelement und ein Teil des Steckprofiles vom Innenleiterelement der Steckeinheit ausgebildet werden. Auf diese Weise kann das Gegensteckprofil sich nicht nur besonders dicht am Isolatorelement der Steckeinheit, sondern auch mit möglichst geringen Abstand am Innenleiterelement der Steckeinheit positioniert werden, wenn Steckeinheit und Gegensteckeinheit miteinander verbunden werden. Das Gegensteckprofil kann ebenfalls teilweise durch das Innenleiterelement der Gegensteckeinheit ausgebildet sein.It can be advantageous if the plug-in profile is partially formed by the inner conductor element of the plug-in unit. Part of the plug-in profile can therefore be formed by the insulator element and part of the plug-in profile can be formed by the inner conductor element of the plug-in unit. In this way, the mating plug-in profile can be positioned not only particularly close to the insulator element of the plug-in unit, but also with the smallest possible spacing on the inner conductor element of the plug-in unit when the plug-in unit and mating plug-in unit are connected to one another. The mating plug-in profile can also be partially formed by the inner conductor element of the mating plug-in unit.

Es kann in diesem Zusammenhang von Vorteil sein, wenn das Innenleiterelement der Steckeinheit und/oder der Gegensteckeinheit im Bereich des Steckprofils einen Profilabschnitt aufweist. Innerhalb des Profilabschnitts kann das Innenleiterelement eine gezielte Formgebung aufweisen, die ein besonders konturnahes aneinander Anliegen von Steckprofil und Gegensteckprofil ermöglichen. Es hat sich gezeigt, dass eine kegelförmige, parabolische und oder bauchige Form besonders geeignet ist. Sofern es sich bei dem Innenleiterelement um eine Kontaktspitze handelt hat es sich als besonders vorteilhaft gewiesen, wenn sich das Innenleiterelement im Profilabschnitt in Richtung Steckseite verjüngt. Handelt es sich bei dem Innenleiterelement um eine Kontaktbuchse hat es sich als vorteilhaft erwiesen, wenn sich das Innenleiterelement im Profilabschnitt in Richtung Steckseite aufweitet. Die Form des Profilabschnitts ist dabei besonders bevorzugt rotationssymmetrisch um eine Mittelachse des Innenleiterelements ausgebildet.In this context, it can be advantageous if the inner conductor element of the plug-in unit and / or the mating plug-in unit has a profile section in the area of the plug-in profile. Within the profile section, the inner conductor element can have a specific shape which enables the plug-in profile and mating plug-in profile to rest particularly closely against one another. It has been shown that a conical, parabolic and / or bulbous shape is particularly suitable. If the inner conductor element is a contact tip, it has proven to be particularly advantageous indicated when the inner conductor element tapers in the profile section in the direction of the plug-in side. If the inner conductor element is a contact socket, it has proven to be advantageous if the inner conductor element expands in the profile section in the direction of the plug-in side. The shape of the profile section is particularly preferably designed to be rotationally symmetrical about a central axis of the inner conductor element.

Das Steckprofil und/oder das Gegensteckprofil können eine Fase aufweisen, die den Innenleiterkanal des jeweiligen Isolatorelements zumindest teilweise umläuft. Die Fase kann sowohl an einer Erhebung als auch an einer Vertiefung des Steckprofils und/oder des Gegensteckprofils angeordnet sein. Die Fase kann dabei an einer dem Innenleiterkanal zugewandten und/oder abgewandten Seite der Erhebung und/oder Vertiefung angeordnet sein. Die Fase kann beispielsweise einen Winkel von 20 bis 70 Grad aufweisen. Sofern die Fase den Innenleiter vollständig umläuft, kann durch zwei gegenüberliegende Fasen ein Winkel von 40 bis 140 Grad eingeschlossen werden. Durch die Fase kann das Steckprofil und/oder das Gegensteckprofil während des Verbindungsprozesses als Führung genutzt werden, so dass auch bei einem schrägen Zusammenstecken von Steckeinheit und Gegensteckeinheit sichergestellt ist, dass alle Bauelemente sicher und elektrisch leitend miteinander verbunden werden. Die Fase kann auch an einer Außenkante des Isolatorelements der Steckeinheit oder Gegensteckeinheit angeordnet sein. Besonders bevorzugt ist die Fase dabei an einer Außenkante der Stirnseite des Isolatorelements der Steckeinheit und/oder Gegensteckeinheit angeordnet, die der jeweiligen Steckseite zugewandt ist.The plug-in profile and / or the mating plug-in profile can have a bevel which at least partially runs around the inner conductor channel of the respective insulator element. The bevel can be arranged both on an elevation and on a depression of the plug-in profile and / or the mating plug-in profile. The bevel can be arranged on a side of the elevation and / or depression facing and / or facing away from the inner conductor channel. The bevel can, for example, have an angle of 20 to 70 degrees. If the bevel runs completely around the inner conductor, an angle of 40 to 140 degrees can be enclosed by two opposing bevels. The bevel allows the plug-in profile and / or the mating plug-in profile to be used as a guide during the connection process, so that even if the plug-in unit and mating plug-in unit are plugged together at an angle, it is ensured that all components are connected to one another in a safe and electrically conductive manner. The bevel can also be arranged on an outer edge of the insulator element of the plug-in unit or mating plug-in unit. Particularly preferably, the bevel is arranged on an outer edge of the end face of the insulator element of the plug-in unit and / or mating plug-in unit that faces the respective plug-in side.

Das Innenleiterelement der Steckeinheit kann einen ersten Kontaktierungsabschnitt umfassen, der aus dem Isolatorelement in Richtung erster Steckseite hervorsteht. Sofern das Innenleiterelement einen Profilabschnitt aufweist, ist es bevorzugt, dass der erste Kontaktierungsabschnitt an den Profilabschnitt angrenzt. Der Kontaktierungsabschnitt kann als Kontaktspitze ausgeführt sein und eine Länge von 2,5 bis 5 Millimetern aufweisen. Weiterhin kann der erste Kontaktierungsabschnitt einen kleinsten Durchmesser des Innenleiterelements aufweisen.The inner conductor element of the plug-in unit can comprise a first contacting section which protrudes from the insulator element in the direction of the first plug-in side. If the inner conductor element has a profile section, it is preferred that the first contacting section adjoins the profile section. The contacting section can be designed as a contact tip and have a length of 2.5 to 5 millimeters. Furthermore, the first contacting section can have the smallest diameter of the inner conductor element.

Der erste Kontaktierungsabschnitt kann in den Innenleiterkanal des Isolatorelements der Gegensteckeinheit einbringbar und mit einem zweiten Kontaktierungsabschnitt des Innenleiterelements der Gegensteckeinheit elektrisch leitend verbindbar sein. Sofern der erste Kontaktierungsabschnitt als Kontaktspitze ausgebildet ist, ist es an dieser Stelle von Vorteil, wenn der zweite Kontaktierungsabschnitt als Kontaktbuchse ausgestaltet ist. Es kann von besonderem Vorteil sein, wenn eine elektrisch leitende Verbindung zwischen ersten und zweiten Kontaktierungsabschnitt erst innerhalb des Innenleiterkanals des Isolatorelements der Gegensteckeinheit erzeugbar ist.The first contacting section can be introduced into the inner conductor channel of the insulator element of the mating plug-in unit and can be connected in an electrically conductive manner to a second contacting section of the inner conductor element of the mating plug-in unit. If the first contacting section is designed as a contact tip, it is advantageous at this point if the second contacting section is designed as a contact socket. It can be of particular advantage if an electrically conductive connection between the first and second contacting section can only be produced within the inner conductor channel of the insulator element of the mating plug-in unit.

Das Innenleiterelement der Gegensteckeinheit kann gegenüber dem der zweiten Steckseite zugewandten Ende des Isolatorelements der Gegensteckeinheit zurückstehen. In diesem Fall wird das Innenleiterelement der Steckeinheit zuerst in den Innenleiterkanal des Innenleiterelements der Gegensteckeinheit eingeführt, bevor das Innenleiterelement der Steckeinheit mit dem Innenleiterelement der Gegensteckeinheit elektrisch leitend verbunden wird. Das Innenleiterelement der Gegensteckeinheit kann gegenüber der Stirnseite des der zweiten Steckseite zugewandten Ende des Isolatorelements um 0,4 bis 1,2 Millimeter zurückstehen.The inner conductor element of the mating plug-in unit can stand back in relation to the end of the insulator element of the mating plug-in unit facing the second plug-in side. In this case, the inner conductor element of the plug-in unit is first inserted into the inner conductor channel of the inner conductor element of the mating plug-in unit before the inner conductor element of the plug-in unit is electrically conductively connected to the inner conductor element of the mating plug-in unit. The inner conductor element of the mating plug-in unit can protrude from the end face of the end of the insulator element facing the second plug-in side by 0.4 to 1.2 millimeters.

Das Isolatorelement der Gegensteckeinheit kann an dem der zweiten Steckseite zugewandten Ende im Bereich des Innenleiterkanals eine Trichterform aufweisen. Die Trichterform kann als Führung dienen, um sicherzustellen, dass beim Verbinden der Steckeinheit mit der Gegensteckeinheit die Innenleiterelemente von Steckeinheit und Gegensteckeinheit elektrisch leitend verbunden werden. Die Trichterform ist besonders dann vorteilhaft, wenn das Innenleiterelement zuerst in den Innenleiterkanal der des Isolatorelements der Gegensteckeinheit eingeführt werden muss, um mit dem Innenleiterelement der Gegensteckeinheit elektrisch leitend verbunden zu werden. Vorzugsweise ist die Trichterform rund ausgebildet, wobei der Mittelpunkt der Trichterform auf der Längsachse des Isolatorelements angeordnet sein kann.The insulator element of the mating plug-in unit can have a funnel shape at the end facing the second plug-in side in the region of the inner conductor channel. The funnel shape can serve as a guide to ensure that when the plug-in unit is connected to the mating plug-in unit, the inner conductor elements of the plug-in unit and mating plug-in unit are connected in an electrically conductive manner. The funnel shape is particularly advantageous when the inner conductor element must first be inserted into the inner conductor channel of the insulator element of the mating connector unit in order to be connected in an electrically conductive manner to the inner conductor element of the mating connector unit. The funnel shape is preferably round, it being possible for the center point of the funnel shape to be arranged on the longitudinal axis of the insulator element.

Die Trichterform kann darüber hinaus das Gegensteckprofil zumindest teilweise ausbilden. Die Trichterform kann sowohl lineare als auch gekrümmte Seitenwände aufweisen. Weiterhin ist es bevorzugt, dass die Trichterform zumindest teilweise der Negativform des Innenleiterelements der Steckeinheit im Bereich des Steckprofils entspricht. In einer besonders bevorzugten Ausgestaltung weist das Isolatorelement zusätzlich zur Trichterform an einer Außenkante eine umlaufende Fase auf, die das Gegensteckprofil teilweise ausbildet.In addition, the funnel shape can at least partially form the mating plug-in profile. The funnel shape can have both linear and curved side walls. Furthermore, it is preferred that the funnel shape at least partially corresponds to the negative shape of the inner conductor element of the plug-in unit in the area of the plug-in profile. In a particularly preferred embodiment, in addition to the funnel shape, the insulator element has a circumferential bevel on an outer edge which partially forms the mating plug-in profile.

Das Steckprofil oder das Gegensteckprofil können eine das Innenleiterelement umlaufende Ringvertiefung aufweisen. Besonders bevorzugt liegt hierbei der Mittelpunkt der Ringvertiefung auf der Längsachse des Innenleiterkanals. Weiterhin kann die Ringvertiefung teilweise durch das Innenleiterelement ausgebildet sein. Die Ringvertiefung kann dabei sowohl rund als auch eckig mit geraden oder gekrümmten Flächen ausgebildet sein.The plug-in profile or the mating plug-in profile can have an annular recess running around the inner conductor element. The center point of the annular recess is particularly preferably located on the longitudinal axis of the inner conductor channel. Furthermore, the ring recess be partially formed by the inner conductor element. The annular recess can be designed both round and angular with straight or curved surfaces.

In einer weiteren Ausgestaltung sind das Außenleiterelement, das Innenleiterelement und das Isolatorelement der Steckeinheit und/oder das Außenleiterelement, das Innenleiterelement und das Isolatorelement der Gegensteckeinheit koaxial zu einander angeordnet und weisen eine gemeinsame Mittelachse auf. Es ist an dieser Stelle besonders bevorzugt, dass das Steckprofil und/oder das Gegensteckprofil eine konzentrische Form und/oder radialsymmetrische Form zur Mittelachse aufweisen.In a further embodiment, the outer conductor element, the inner conductor element and the insulator element of the plug-in unit and / or the outer conductor element, the inner conductor element and the insulator element of the mating plug-in unit are arranged coaxially to one another and have a common central axis. It is particularly preferred at this point that the plug-in profile and / or the mating plug-in profile have a concentric shape and / or a radially symmetrical shape with respect to the central axis.

Die Steckeinheit 4 ist mit einem Kabel 2 elektrisch leitend verbunden. Im vorliegenden Ausführungsbeispiel handelt es sich bei dem Kabel 2 um ein Koaxialkabel. Das Gegensteckelement 5 ist mit einem elektrischen Bauelement 3 elektrisch leitend und unlösbar verbunden. Im vorliegenden Ausführungsbeispiel handelt es sich bei der elektrischen Bauelement 3 ebenfalls um ein Koaxialkabel. Die Steckeinheit 4 und die Gegensteckeinheit 5 setzen sich jeweils aus einem Außenleiterelement 6, 7, einem Isolatorelement 8, 9 und einem Innenleiterelement 10, 11 zusammen. Die Isolatorelemente 8, 9 weisen jeweils einen Innenleiterkanal 12, 13 auf. Die Außenleiterelemente 6, 7 sind als Hülsen aus Bronze ausgeführt, so dass die Isolatorelemente, 8, 9 vollständig innerhalb der Außenleiterelemente 6, 7 angeordnet sind. Die Isolatorelemente 8, 9 bestehen aus Kunststoff und weisen eine zylinderförmige Geometrie auf. Die aus Bronze bestehenden Innenleiterelemente 10, 11 sind jeweils im Innenleiterkanal 12, 13 der Isolatorelemente 8, 9 angeordnet. Die Außenleiterelemente 6, 7 sind jeweils elektrisch leitend mit einer Schirmung 27 verbunden und über ein Dielektrikum 29 des jeweiligen Kabels 2, 3 gestülpt. Die Innenleiterelemente 10, 11 sind mit Litzen 28, der Kabel 2, 3 vercrimpt. In der vorliegenden Ausführungsform wird die Schirmung 27 durch ein Drahtgeflecht ausgebildet. Figure 1 shows a first embodiment of a connector arrangement 1 according to the invention in a sectional view. The sectional plane runs along a longitudinal axis of the plug connector arrangement 1. The plug connector arrangement 1 comprises a lancing unit 4 and a mating plug unit 5. The plug unit 4 is provided with a cable 2 electrically connected. In the present exemplary embodiment, the cable 2 is a coaxial cable. The mating plug element 5 is connected to an electrical component 3 in an electrically conductive and non-detachable manner. In the present exemplary embodiment, the electrical component 3 is also a coaxial cable. The plug-in unit 4 and the mating plug-in unit 5 are each composed of an outer conductor element 6, 7, an insulator element 8, 9 and an inner conductor element 10, 11. The insulator elements 8, 9 each have an inner conductor channel 12, 13. The outer conductor elements 6, 7 are designed as sleeves made of bronze, so that the insulator elements 8, 9 are arranged completely within the outer conductor elements 6, 7. The isolator elements 8, 9 are made of plastic and have a cylindrical geometry. The inner conductor elements 10, 11 made of bronze are each arranged in the inner conductor channel 12, 13 of the insulator elements 8, 9. The outer conductor elements 6, 7 are each connected in an electrically conductive manner to a shield 27 and placed over a dielectric 29 of the respective cable 2, 3. The inner conductor elements 10, 11 are crimped with strands 28, the cables 2, 3. In the present embodiment, the shield 27 is formed by a wire mesh.

Die Steckeinheit 4 weist eine erste Steckseite 14 auf, wobei die Gegensteckeinheit 5 eine zweite Steckseite 19 aufweist. Die Steckeinheit 4 und die Gegensteckeinheit 5 sind mit einander zugewandter erster und zweiter Steckseite 14, 19 ineinandergesteckt. Das Außenleiterelement 6 der Steckeinheit 4 weist hierzu in dem Bereich, in dem die Steckeinheit 4 und die Gegensteckeinheit 5 ineinandergesteckt werden, einen Außendurchmesser auf, der kleiner ist als der Innendurchmesser das Außenleiterelement 7 der Gegensteckeinheit 5 in dem gleichen Bereich. Weiterhin weist das Außenleiterelement 7 der Gegensteckeinheit 5 eine Kontaktfeder auf, um die Steckeinheit 4 kraftschlüssig zu fixieren und eine stabile elektrisch leitende Verbindung zwischen beiden Außenleiterelementen 6, 7 herzustellen. In der dargestellten Ansicht sind Steckeinheit 4 und Gegensteckeinheit 5 bereits ineinandergesteckt. Die Außenleiterelemente 6, 7, die Isolatorelemente 8, 9 und die Innenleiterelemente 10, 11 der Steckeinheit 4 und der Gegensteckeinheit 5 sind im vorliegenden Ausführungsbeispiel mit Ihrer Längsachse auf einer gemeinsamen Mittelachse 26 angeordnet.The plug-in unit 4 has a first plug-in side 14, the mating plug-in unit 5 having a second plug-in side 19. The plug-in unit 4 and the mating plug-in unit 5 are plugged into one another with the first and second plug-in sides 14, 19 facing one another. For this purpose, the outer conductor element 6 of the plug-in unit 4 has an outer diameter in the area in which the plug-in unit 4 and the mating plug-in unit 5 are plugged into one another, which is smaller than the inner diameter of the outer conductor element 7 of the mating plug-in unit 5 in the same area. Furthermore, the outer conductor element 7 of the mating plug-in unit 5 has a contact spring in order to fix the plug-in unit 4 in a non-positive manner and to establish a stable, electrically conductive connection between the two outer conductor elements 6, 7. In the view shown, plug-in unit 4 and mating plug-in unit 5 are already plugged into one another. The outer conductor elements 6, 7, the insulator elements 8, 9 and the inner conductor elements 10, 11 of the plug-in unit 4 and the mating plug-in unit 5 are arranged with their longitudinal axis on a common central axis 26 in the present exemplary embodiment.

Figur 2 zeigt eine vergrößerte Darstellung der ersten Ausführungsform der erfindungsgemäßen Steckverbinderanordnung 1 in einer Schnittansicht. Die Steckverbinderanordnung 1 befindet sich in einer Steckposition, wobei die Steckeinheit 4 und die Gegensteckeinheit 5 im größtmöglichen Abstand zueinander positioniert sind. Dieser größtmögliche Abstand kann beispielsweise durch Toleranzen der einzelnen Bauteile oder durch ein gewisses gewünschtes Spiel zwischen den Bauteilen bedingt sein. Das Isolatorelement 8 der Steckeinheit 4 besitzt an einem der ersten Steckseite 14 zugewandten Ende 15 an einer Stirnseite ein Steckprofil 16. Das Steckprofil 16 wird in der vorliegenden Ausführungsform zum einen durch eine an den Innenleiterkanal 12 angrenzende und den Innenleiterkanal 12 ringförmig umlaufende Vertiefung 18 ausgebildet. Zum anderen wird das Steckprofil 16 durch einen Profilabschnitt 22 des Innenleiterelements 10 ausgebildet. Das Isolatorelement 9 der Gegensteckeinheit 5 besitzt an einer Stirnseite eines der zweiten Steckseite 19 zugewandten Ende 20 ein Gegensteckprofil 21. Das Gegensteckprofil 19 entspricht im Wesentlichen der Negativform des Steckprofils 16. Hierzu besitzt das Isolatorelement 9 der Gegensteckeinheit 5 an der Stirnseite eine Erhebung 17, die ringförmig um den Innenleiterkanal 13 verläuft. Figure 2 shows an enlarged illustration of the first embodiment of the connector arrangement 1 according to the invention in a sectional view. the The connector arrangement 1 is in a plug-in position, the plug-in unit 4 and the mating plug-in unit 5 being positioned at the greatest possible distance from one another. This greatest possible distance can be caused, for example, by tolerances of the individual components or by a certain desired play between the components. The insulator element 8 of the plug-in unit 4 has a plug-in profile 16 on one end 15 facing the first plug-in side 14. On the other hand, the plug profile 16 is formed by a profile section 22 of the inner conductor element 10. The insulator element 9 of the mating plug-in unit 5 has a mating plug-in profile 21 on one end 20 facing the second plug-in side 19 runs in a ring around the inner conductor channel 13.

Das Innenleiterelement 10 des Steckelements 4 besitzt einen ersten Kontaktierungsabschnitt 24, der sich an den Profilabschnitt 22 anschließt und als Kontaktspitze ausgebildet ist. Die Kontaktspitze steht von dem Isolatorelement 8 der Steckeinheit 4 in Richtung erster Steckseite 14 hervor. Weiterhin verjüngt sich das Innenleiterelement 10 über den Profilabschnitt 22 zum Kontaktierungsabschnitt 24 auf einen kleineren Außendurchmesser. Das Innenleiterelement 11 der Gegensteckeinheit 5 steht gegenüber der Stirnseite am der zweiten Steckeinheit zugewandten Ende 20 des Isolatorelements 9 zurück, wobei sich der Innenleiterkanal 13 bis zur Stirnseite hin erstreckt. Das Innenleiterelement 11 der Gegensteckeinheit 5 besitzt einen zweiten Kontaktierungsabschnitt 25, der als Kontaktbuchse ausgebildet ist. Die Kontaktbuchse weist einen Innendurchmesser auf, der größer ist als der Außendurchmesser des ersten Kontaktierungsabschnitts 24 des Innenleiterelements 10 der Steckeinheit 4. Um einen elektrisch leitenden Kontakt zwischen den Kontaktierungsabschnitten 24, 25 herstellen zu können, wird der erste Kontaktierungsabschnitt 24 zuerst in den Innenleiterkanal 13 der Gegensteckeinheit 5 eingeführt. Anschließende taucht der erste Kontaktierungsabschnitt 24 in den zweiten Kontaktierungsabschnitt 25 ein.The inner conductor element 10 of the plug element 4 has a first contacting section 24, which adjoins the profile section 22 and is designed as a contact tip. The contact tip protrudes from the insulator element 8 of the plug-in unit 4 in the direction of the first plug-in side 14. Furthermore, the inner conductor element 10 tapers over the profile section 22 to the contacting section 24 to a smaller outer diameter. The inner conductor element 11 of the mating plug-in unit 5 is set back opposite the end face at the end 20 of the insulator element 9 facing the second plug-in unit, the inner conductor channel 13 extending up to the end face. The inner conductor element 11 of the mating connector unit 5 has a second contacting section 25 which is designed as a contact socket. The contact socket has an inner diameter that is greater than the outer diameter of the first contacting section 24 of the inner conductor element 10 of the plug-in unit 4 Mating connector unit 5 introduced. The first contacting section 24 then dips into the second contacting section 25.

Figur 3 zeigt eine weitere Darstellung der ersten Ausführungsform der erfindungsgemäßen Steckverbinderanordnung 1 in einer Schnittansicht. In der gezeigten Darstellung befindet sich die Steckverbinderanordnung 1 ebenfalls in der Steckposition, die Steckeinheit 4 und die Gegensteckeinheit 5 im toleranzbedingten kleinstmöglichen Abstand zueinander positioniert sind. Der erste Kontaktierungsabschnitt 24 ist elektrisch leitend mit dem zweiten Kontaktierungsabschnitt 25 verbunden. Darüber hinaus liegen das Steckprofil 16 und das Gegensteckprofil 21 aneinander an. Die Erhebung 17 des Gegensteckprofils 21 schmiegt sich also an die Formgebung der Vertiefung 18 des Steckprofils 16 an. Das Innenleiterelement 10 der Steckeinheit 4 besitzt im Profilabschnitt 22 eine bauchige, sich zum ersten Kontaktierungsabschnitt 24 verjüngende Form, so dass der Profilabschnitt 22 zusammen mit der Vertiefung 18 im Isolatorelement 8 eine das Innenleiterelement 10 umlaufende Ringvertiefung besitzt, deren Mittelpunkt auf der Mittelachse 26 angeordnet ist. Figure 3 shows a further illustration of the first embodiment of the connector arrangement 1 according to the invention in a sectional view. Located in the illustration shown the connector arrangement 1 is likewise in the plug-in position, the plug-in unit 4 and the mating plug-in unit 5 are positioned at the smallest possible distance from one another due to the tolerance. The first contact section 24 is connected to the second contact section 25 in an electrically conductive manner. In addition, the plug-in profile 16 and the mating plug-in profile 21 rest against one another. The elevation 17 of the mating plug-in profile 21 therefore hugs the shape of the recess 18 of the plug-in profile 16. The inner conductor element 10 of the plug-in unit 4 has a bulbous shape in the profile section 22, tapering towards the first contacting section 24, so that the profile section 22 together with the depression 18 in the insulator element 8 has an annular depression that encircles the inner conductor element 10, the center of which is arranged on the central axis 26 .

Figur 4 zeigt eine weitere vergrößerte Darstellung der ersten Ausführungsform der erfindungsgemäßen Steckverbinderanordnung 1 in einer Schnittansicht im Bereich des Steckprofils 16 und des Gegensteckprofils 21 in der Steckposition. Das Gegensteckprofil 21 besitzt an einer Außenkante des der zweiten Steckseite 19 zugewandten Endes 20 des Isolatorelements 9 eine Fase 23, die sich von einer äußeren Mantelfläche des Isolatorelements 9 bis zu der Erhebung 18 erstreckt. Die Vertiefung 17 des Steckprofils 16 weist eine komplementäre Fase 23 auf. Durch die Fase 23 sowohl an Steckprofil 16 als auch an Gegensteckprofil 21 werden die beiden Isolatorelemente 8, 9 auch bei einem leicht schrägen Zusammenstecken, das beispielsweise toleranzbedingt möglich sein kann, derart zueinander geführt, dass beide Isolatorelemente 8, 9 spätestens bei Erreichen der Steckposition in definierter Position zueinander angeordnet sind. Das Isolatorelement 9 der Gegensteckeinheit 5 besitzt an der Stirnseite eine Trichterform, die sich um den Innenleiterkanal 13 erstreckt. Durch die Trichterform kann zum einen sichergestellt werden, dass das Gegensteckprofil 21 auch in Bereich des Steckprofils 16, der durch den Profilabschnitt 22 des Innenleiterelements 10 ausgebildet wird, zumindest teilweise eine Negativform des Steckprofils 16 ausbilden kann. Weiterhin kann durch die Trichterform sichergestellt werden, dass beim Zusammenstecken von Steckeinheit 4 und Gegensteckeinheit 5 das Innenleiterelement 10 der Steckeinheit 4 ohne Beschädigungen in den Innenleiterkanal 13 des Isolatorelements 9 der Gegensteckeinheit 5 geführt werden kann. Figure 4 shows a further enlarged illustration of the first embodiment of the connector arrangement 1 according to the invention in a sectional view in the area of the plug-in profile 16 and the mating plug-in profile 21 in the plug-in position. The mating plug-in profile 21 has on an outer edge of the end 20 of the insulator element 9 facing the second plug-in side 19 a bevel 23 which extends from an outer jacket surface of the insulator element 9 to the elevation 18. The recess 17 of the plug profile 16 has a complementary bevel 23. Due to the bevel 23 on both the plug profile 16 and the mating plug profile 21, the two insulator elements 8, 9 are guided to one another even when they are plugged together at a slight angle, which may be possible due to tolerances, for example, that both insulator elements 8, 9 are in are arranged in a defined position to each other. The end face of the insulator element 9 of the mating plug-in unit 5 has a funnel shape which extends around the inner conductor channel 13. On the one hand, the funnel shape ensures that the mating plug-in profile 21 can also at least partially form a negative shape of the plug-in profile 16 in the region of the plug-in profile 16, which is formed by the profile section 22 of the inner conductor element 10. Furthermore, the funnel shape ensures that when plug-in unit 4 and mating plug-in unit 5 are plugged together, inner conductor element 10 of plug-in unit 4 can be guided into inner-conductor channel 13 of insulator element 9 of mating plug-in unit 5 without damage.

In Figur 5 ist in einer weiteren Darstellung der ersten Ausführungsform der Steckverbinderanordnung 1 in einer Schnittansicht der Steckprozess des Innenleiterelements 10 der Steckeinheit 4 in den Innenleiterkanal 13 des Isolatorelements 9 der Gegensteckeinheit 5 dargestellt. Obwohl die Steckeinheit 4 und die Gegensteckeinheit 5 nicht genau parallel, sondern leicht schräg ineinandergesteckt werden, wird der erste Kontaktierungsabschnitt 24 durch die Trichterform in den Innenleiterkanal 13 des Isolatorelements 9 geführt. Das Risiko, dass das Innenleiterelement 10 der Steckeinheit 4 gegen das Isolatorelement 9 der Gegensteckeinheit 5 gedrückt und verformt oder gar abgebrochen wird, kann somit deutlich reduziert werden.In Figure 5 is in a further illustration of the first embodiment of the connector arrangement 1 in a sectional view of the plugging process of Inner conductor element 10 of the plug-in unit 4 is shown in the inner conductor channel 13 of the insulator element 9 of the mating plug-in unit 5. Although the plug-in unit 4 and the mating plug-in unit 5 are not plugged into one another exactly parallel, but rather at a slight angle, the first contacting section 24 is guided through the funnel shape into the inner conductor channel 13 of the insulator element 9. The risk that the inner conductor element 10 of the plug-in unit 4 is pressed against the insulator element 9 of the mating plug-in unit 5 and is deformed or even broken off can thus be significantly reduced.
