Description

Die Erfindung betrifft eine Steckverbindung mit einem ersten und einem zweiten Steckverbinder. Insbesondere betrifft die Erfindung eine Mehrfachsteckverbindung zur elektrisch leitenden, zur Übertragung von Hochfrequenzsignalen vorgesehenen Verbindung von zwei Leiterplatten.The invention relates to a plug connection with a first and a second connector. In particular, the invention relates to a multi-pin connector for electrically conductive, provided for the transmission of high-frequency signals connection of two printed circuit boards.

Derartige Steckverbindungen sollen eine möglichst verlustfreie Übertragung der Hochfrequenzsignale auch in einem definierten Toleranzbereich bezüglich der Parallelität sowie des Abstands der beiden Leiterplatten sicherstellen. Weitere Anforderungen an solche Kontaktelemente liegen in einer kostengünstigen Herstellung sowie einer einfachen Montage.Such connectors are to ensure a loss-free as possible transmission of high-frequency signals in a defined tolerance range with respect to the parallelism and the distance of the two circuit boards. Other requirements for such contact elements are a cost-effective production and easy installation.

Bekannt ist, eine einfache (d.h. einen Hochfrequenzsignalpfad ausbildende) Verbindung zwischen zwei Leiterplatten mittels zwei, mit den Leiterplatten fest verbundenen Koaxialsteckverbindern sowie einem die beiden Koaxialsteckverbinder verbindenden Adapter, dem sogenannten "Bullet", herzustellen. Dieser Adapter ermöglicht einen axialen und radialen Toleranzausgleich, sowie den Ausgleich von Parallelitätstoleranzen. Typische hierfür eingesetzte Koaxialsteckverbinder sind SMP, Mini-SMP oder FMC.It is known to produce a simple (i.e., a high frequency signal path forming) connection between two printed circuit boards by means of two coaxial connectors fixedly connected to the printed circuit boards and an adapter, the so-called "bullet", connecting the two coaxial connectors. This adapter allows axial and radial tolerance compensation, as well as the compensation of parallelism tolerances. Typical coaxial connectors used for this purpose are SMP, mini-SMP or FMC.

Alternativ werden elektrische Verbindungen zwischen zwei Leiterplatten auch über Federkontaktstifte, sogenannte "Pogopins", in Einzelleiter- und/oder Mehrfachleiteraufbau realisiert. Derartige Federkontaktstifte umfassen eine Hülse und einen teilweise innerhalb der Hülse geführten Kopf sowie eine Schraubenfeder, die sich zwischen dem Kopf und der Hülse abstützt. Die für die Schraubenfeder geforderten Eigenschaften bezüglich Federkraft und Blocklänge erfordern relativ große Federlängen, die sich entsprechend auf die axiale Bauhöhe der Federkontaktstifte auswirken. Die Verwendung von Federkontaktstiften im Einzelleiteraufbau weist zudem das Erfordernis auf, dass diese in einem bestimmten Muster als Signal- und Groundpins angeordnet sein müssen, um eine befriedigende elektrische Leistung zu erzielen. Mehrfachleiter sind dagegen aufgrund ihres komplizierten Aufbaus fehleranfällig und teuer.Alternatively, electrical connections between two printed circuit boards are also realized via spring contact pins, so-called "pogopins", in single-conductor and / or multiple-conductor construction. Such spring contact pins include a sleeve and a partially guided within the sleeve head and a coil spring which is supported between the head and the sleeve. The required properties for the coil spring with respect to spring force and block length require relatively large spring lengths, which have a corresponding effect on the axial height of the spring contact pins. The use of spring contact pins in Einzelleiteraufbau also has the Require that they must be arranged in a specific pattern as signal and ground pins in order to achieve a satisfactory electrical performance. Multiple conductors, however, are prone to error and expensive due to their complicated structure.

Die Druckschrift US 6,471,523 B1 beschreibt eine Steckverbindung aus zwei Steckverbindern, wobei die Kontakte eines der beiden Steckverbinder elastisch auslenkbar ausgebildet sind. Dabei ist ein innerer Kontakt von zwei äußeren Kontakten umgeben.The publication US Pat. No. 6,471,523 B1 describes a connector of two connectors, wherein the contacts of one of the two connectors are formed elastically deflectable. An inner contact is surrounded by two external contacts.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, eine verbesserte Steckverbindung anzugeben. Insbesondere sollte sich die Steckverbindung trotz Toleranzen ausgleichender Eigenschaften durch eine kostengünstige Herstellung, einen einfachen Aufbau und/oder eine einfache Montage auszeichnen.Based on this prior art, the present invention seeks to provide an improved connector. In particular, the connector should be characterized despite tolerances balancing properties by a cost-effective production, a simple structure and / or easy installation.

Diese Aufgabe wird durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Steckverbindung sind Gegenstand der abhängigen Ansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.This object is solved by the subject matter of independent claim 1. Advantageous embodiments of the connector according to the invention are the subject of the dependent claims and will become apparent from the following description of the invention.

Eine gattungsgemäße Steckverbindung, die zumindest einen ersten Steckverbinder und einen zweiten Steckverbinder umfasst, wobei die Steckverbinder jeweils mindestens zwei Kontaktelemente aufweisen und wobei die Kontaktelemente des ersten Steckverbinders die Kontaktelemente des zweiten Steckverbinders im gesteckten Zustand der Steckverbindung an Kontaktstellen kontaktieren, ist erfindungsgemäß dadurch weitergebildet, dass die Kontaktelemente beider Steckverbinder in Form von in einen Freiraum (und vorzugsweise vollständig frei in den Raum) ragenden, elastisch auslenkbaren Kontaktlaschen ausgebildet sind. Die Kontaktlaschen des zweiten Steckverbinders werden jeweils von mehreren Kontaktfederlaschen des ersten Steckverbinders zangenartig kontaktiert. Die Steckverbindung weist die weiteren Merkmale gemäß Patentanspruch 1 auf.A generic connector comprising at least a first connector and a second connector, the connectors each having at least two contact elements and wherein the contact elements of the first connector contact the contact elements of the second connector in the inserted state of the connector at contact points, according to the invention further developed in that the contact elements of both connectors in the form of in a free space (and preferably completely free in the space) projecting, elastically deflectable contact tabs are formed. The contact tabs of the second connector are each contacted by a plurality of contact spring tabs of the first connector pincers. The connector has the further features according to claim 1.

Durch diese Ausgestaltung kann trotz eines einfachen konstruktiven Aufbaus ein Ausgleich auch von vergleichsweise großen Toleranzen erreicht werden, da beide Kontaktseiten, d.h. die Kontaktelemente des einen Steckverbinders und die Kontaktelemente des anderen Steckverbinders, durch die Möglichkeit einer elastischen Auslenkung - so fern erforderlich - zu dem Toleranzausgleich beitragen können.By virtue of this embodiment, compensation can be achieved even for comparatively large tolerances, despite a simple construction, since both sides of the contact, i. the contact elements of a connector and the contact elements of the other connector, by the possibility of elastic deflection - so far required - can contribute to the tolerance compensation.

Unter "Kontaktlasche" wird erfindungsgemäß ein Kontaktelement verstanden, das sich von einer Anbindungsstelle, in der dieses fest mit einem anderen Bauteil verbunden ist, in seiner Längsrichtung in einen (zumindest teilweise, vorzugsweise vollumfänglich freien Raum erstreckt, wobei das Kontaktelemente bei Druck in einer Richtung quer zur Längsrichtung elastisch ausgelenkt wird und dadurch eine funktionale, toleranzausgleichende Federwirkung bereitstellt. Vorzugsweise weist eine solche erfindungsgemäße Kontaktlasche eine flächige Bauform (mit einer Höhe, die nur einen Bruchteil der Breite und der Länge beträgt, wobei die Breite vorzugsweise zudem geringer als die Länge ist) auf."Contact tab" is understood according to the invention as a contact element which extends from a connection point in which it is firmly connected to another component in its longitudinal direction in a (at least partially, preferably fully free space, wherein the contact elements in one direction Preferably, such a contact clip according to the invention has a flat design (with a height which is only a fraction of the width and the length, wherein the width is preferably also smaller than the length ) on.

Die erfindungsgemäße Steckverbindung ist vorzugsweise zur Übertragung von Hochfrequenzsignalen vorgesehen.The connector according to the invention is preferably provided for the transmission of high-frequency signals.

Dabei ist vorgesehen, dass die Kontaktlaschen jedes Steckverbinders in Form von koaxialen Kontaktelementepaaren angeordnet sind, d.h. eine erste Kontaktlasche ist jeweils Teil eines Innenleiters des entsprechenden Steckverbinders und eine zweite Kontaktlasche ist jeweils Teil eines den Innenleiter umgebenden Außenleiters des entsprechenden Steckverbinders. Ferner ist dabei noch vorgesehen, dass auch die Kontaktlaschen der Innenleiter jeweils von den Kontaktlaschen der Außenleiter umgeben sind. Durch diese Ausgestaltung kann auch im Bereich der Kontaktlaschen eine Abschirmung des als Signalleiter dienenden Innenleiters durch den Außenleiter gegen elektromagnetische Störungen und zudem, bei einer vorzugsweise vorgesehenen Ausgestaltung der Steckverbindung als Mehrfachsteckverbindung, ein Übersprechen zwischen den Kontaktelementepaaren verringert werden.It is provided that the contact tabs of each connector are arranged in the form of coaxial pairs of contact elements, ie, a first contact tab is part of an inner conductor of the corresponding connector and a second contact tab is in each case part of an inner conductor surrounding outer conductor of the corresponding connector. Furthermore, it is also provided that the contact tabs of the inner conductor are each surrounded by the contact tabs of the outer conductor. As a result of this configuration, a shielding of the inner conductor serving as a signal conductor by the outer conductor against electromagnetic interference and, in the case of a preferably provided configuration of the plug connection as a multiple plug connection, a crosstalk between the pairs of contact elements can also be reduced.

Ferner ist vorgesehen, dass die Kontaktlaschen des ersten Steckverbinders als Kontaktfederlaschen ausgebildet sind.It is further provided that the contact tabs of the first connector are formed as contact spring tabs.

Als "Kontaktfederlaschen" werden erfindungsgemäß solche Kontaktlaschen verstanden, bei denen eine elastische Auslenkung nicht nur zum Zweck eines Toleranzausgleichs erfolgt, sondern auch bei der Kontaktierung mit dem entsprechenden Gegenkontaktelement vorgesehen ist. Eine Funktion der Federkontaktlaschen ist demnach auch, einen ausreichenden Kontaktdruck an den Kontaktstellen durch eine elastische Rückstellkraft bereitzustellen.As "contact spring tabs" according to the invention such contact tabs understood in which an elastic deflection is not only for the purpose of tolerance compensation, but is also provided in the contact with the corresponding mating contact element. A function of the spring contact tabs is therefore also to provide a sufficient contact pressure at the contact points by an elastic restoring force.

Für eine besonders gute und sichere Kontaktierung der Kontaktelemente der beiden Steckverbinder auch bei sehr großen Toleranzen kann weiterhin vorgesehen sein, dass doppelte Kontaktlaschen eines der Steckverbinder einfache Kontaktlaschen des anderen Steckverbinders zangenartig umgreifen. Besonders bevorzugt sind dabei die doppelten Kontaktlaschen in Form von Kontaktfederlaschen ausgebildet.For a particularly good and secure contacting of the contact elements of the two connectors even with very large tolerances can be further provided that double contact tabs of one of the connectors simple contact tabs of the other connector pincers surround. Particularly preferably, the double contact tabs in the form of contact spring tabs are formed.

Eine einfache und somit kostengünstige Möglichkeit zur Herstellung einer erfindungsgemäßen Steckverbindung kann vorsehen, dass die Kontaktlaschen und insbesondere die gesamten Innen- und Außenleiter in Form von Stanzbiegebauteilen ausgebildet sind.A simple and thus cost-effective way of producing a plug connection according to the invention can provide that the contact tabs and in particular the entire inner and outer conductors are formed in the form of stamped and bent components.

In einer weiterhin bevorzugten Ausgestaltung der erfindungsgemäßen Steckverbindung kann vorgesehen sein, dass jeweils zwischen den Außenleitern und Innenleitern der Steckverbinder Isolationskörper angeordnet sind. Diese Isolationskörper können dabei nicht nur eine Isolationsfunktion haben, sondern auch zur Stabilität der Steckverbinder beitragen und besonders bevorzugt ein die Innen- und Außenleiter (und vorzugsweise auch die Kontaktelemente) zumindest teilweise umgebendes Gehäuse für den einen oder beide Steckverbinder ausbilden. Dabei kann das Gehäuse auch Teil des Steckinterfaces sein, das z.B. die Steckbewegung der Steckverbinder führt, eine solche nur in einer Ausrichtung der Steckverbinder zueinander zulässt und/oder eine mechanische Fixierung der Steckverbinder im gesteckten Zustand bewirkt.In a further preferred embodiment of the connector according to the invention can be provided that are arranged in each case between the outer conductors and inner conductors of the connector insulation body. This insulation body can not only have an insulation function, but also contribute to the stability of the connector and more preferably a the inner and outer conductors (and preferably also the contact elements) at least partially surrounding housing for one or both connectors form. The housing can also be part of it be the plug-in interface, which leads, for example, the plug movement of the connector, such a permitting each other only in an orientation of the connector and / or causes a mechanical fixation of the connector in the inserted state.

Um eine reflexionsarme Übertragung von Hochfrequenzsignalen mittels der erfindungsgemäßen Steckverbindung zu erreichen, sollten Impedanzänderungen für den Signalleiter vermieden werden. Da die Impedanz maßgeblich von dem Signalleiter (Werkstoff und Querschnitt, insbesondere Querschnittsgröße) sowie dem diesen umgebenden Dielektrikum beeinflusst wird, ist in einer weiterhin bevorzugten Ausgestaltung vorgesehen, dass die Querschnitte der von den Innenleitern ausgebildeten Kontaktlaschen gegenüber den Querschnitten der von den Isolationskörpern umgebenden Abschnitte der Innenleiter derart unterschiedlich gewählt sind, dass sich eine im Wesentlichen gleiche Impedanz ergibt. Regelmäßig wird dafür vorgesehen sein, die Querschnittsfläche der regelmäßig von Luft als Dielektrikum umgebenen Kontaktlaschen größer auszubilden, als die Querschnittsflächen der von den Isolationskörpern umgebenen Abschnitte der Innenleiter.In order to achieve a reflection-poor transmission of high-frequency signals by means of the connector according to the invention, impedance changes should be avoided for the signal conductor. Since the impedance is decisively influenced by the signal conductor (material and cross-section, in particular cross-sectional size) and the surrounding dielectric, it is provided in a further preferred embodiment that the cross sections of the contact tabs formed by the inner conductors with respect to the cross sections of the surrounding of the insulating bodies sections Inner conductor are chosen so different that results in a substantially equal impedance. Regularly, it will be provided that the cross-sectional area of the contact plates, which are regularly surrounded by air as a dielectric, is greater than the cross-sectional areas of the sections of the inner conductors surrounded by the insulating bodies.

Die erfindungsgemäße Ausgestaltung ermöglicht in vorteilhafter Weise die Ausbildung einer Mehrfachsteckverbindung, bei der der erste Steckverbinder und der zweite Steckverbinder eine Mehrzahl von Innen-/Außenleiter-Paaren aufweisen. Bei einer solchen Mehrfachsteckverbindung kann vorteilhafterweise dann auch vorgesehen sein, dass sich der vorzugsweise einteilige Isolationskörper sowohl zwischen die Innenleiter und Außenleiter der Innen-/Außenleiter-Paare als auch zwischen die Innen-/Außenleiter-Paare selbst erstreckt. Eine besonders bevorzugte Ausgestaltung kann somit vorsehen, einen oder beide der Mehrfachsteckverbinder aus einem einzigen einteiligen Isolationskörper mit darin angeordneten oder daran befestigten Innen- und Außenleitern auszubilden. Ein solcher Mehrfachsteckverbinder kann besonders kostengünstig herstellbar und montierbar sein.The embodiment of the invention advantageously allows the formation of a multi-pin connector, wherein the first connector and the second connector having a plurality of inner / outer conductor pairs. In such a multi-pin connector can then advantageously be provided that the preferably one-piece insulating body extends both between the inner conductor and outer conductor of the inner / outer conductor pairs and between the inner / outer conductor pairs themselves. A particularly preferred embodiment may thus provide for forming one or both of the multiple plug-in connectors from a single one-piece insulation body with inner and outer conductors arranged therein or attached thereto. Such a multiple connector can be particularly inexpensive to produce and assemble.

Die erfindungsgemäße Steckverbindung eignet sich vorteilhaft zur Verbindung von zwei Leiterplatten, d.h. als sogenannte Board-to-Board- oder B2B-Verbindung. Hierzu kann vorgesehen sein, dass der/die Innenleiter und/oder der/die Außenleiter von zumindest einem der, vorzugsweise von beiden Steckverbindern an ihren den Kontaktlaschen gegenüberliegenden Enden Kontaktbereiche zur Kontaktierung von Leiterbahnen einer Leiterplatte ausbilden. Diese Kontaktbereiche können vorzugsweise in Form von bogenförmig verlaufenden oder abgewinkelten Abschnitten der Innen-und/oder Außenleiter ausgebildet sein.The connector according to the invention is advantageous for Connection of two printed circuit boards, ie as so-called board-to-board or B2B connection. For this purpose, it may be provided that the inner conductor (s) and / or the outer conductor (s) of at least one of the two connectors form contact regions for contacting printed conductors of a printed circuit board at their ends opposite the contact tabs. These contact regions may preferably be in the form of arcuately extending or angled sections of the inner and / or outer conductors.

Weiterhin bevorzugt kann dann auch vorgesehen sein, dass der Isolationskörper Verbindungsmittel zum Verbinden mit einer Leiterplatte ausbildet. Diese Verbindungsmittel können beispielsweise in Form von Rastlaschen ausgebildet sein.Further preferably, it can then also be provided that the insulation body forms connecting means for connection to a printed circuit board. This connecting means may be formed, for example in the form of locking tabs.

Die in den Fig. 1 bis 7 dargestellte Steckverbindung umfasst einen ersten Steckverbinder 1 und einen zweiten Steckverbinder 2. Jeder der Steckverbinder 1, 2 umfasst eine Mehrzahl von (konkret vier) jeweils aus Innenleiter 3 und Außenleiter 4 bestehenden Leiterpaaren, die in einer koaxialen Anordnung vorgesehen sind. Die Innenleiter 3 und Außenleiter 4 der Steckverbinder 1, 2 sind in bzw. an jeweils einem Isolationskörper 5 gehalten, der nicht nur die Innenleiter 3 und Außenleiter 4 der einzelnen Leiterpaare voneinander, sondern auch die Leiterpaare untereinander elektrisch isoliert, alle Leiter mechanisch fixiert und zudem ein Gehäuse mit Befestigungsmitteln ausbildet, das ermöglicht, die Steckverbinder 1, 2 jeweils an einer Leiterplatte (nicht dargestellt) zu befestigen.The in the Fig. 1 to 7 Each of the connectors 1, 2 comprises a plurality of (specifically four) each consisting of inner conductor 3 and outer conductor 4 conductor pairs, which are provided in a coaxial arrangement. The inner conductor 3 and outer conductor 4 of the connector 1, 2 are held in or on each of an insulating body 5, which not only the inner conductor 3 and outer conductor 4 of the individual pairs of conductors from each other, but also the pairs of conductors electrically insulated from each other, mechanically fixed all conductors and also forms a housing with fastening means, which makes it possible to attach the connectors 1, 2 respectively to a printed circuit board (not shown).

Sämtliche Leiter sind als Stanz- oder Stanzbiegebauteile hergestellt, d.h. aus einem elektrisch leitenden Blech ausgestanzt und dann ggf. umgeformt, was eine kostengünstige Großserienfertigung ermöglicht. Sämtliche Leiter weisen zudem Abschnitte auf, in denen diese zumindest einseitig an den dazugehörigen Isolationskörpern 5 angrenzen und zu diesen weitgehend unbeweglich sind. Weiterhin bilden alle Leiter Kontaktbereiche 6 aus, die für einen Kontakt mit einem dazugehörigen Kontaktbereich der entsprechenden Leiterplatte vorgesehen sind. Zudem werden von den Leitern Kontaktlaschen 7 ausgebildet, die Kontaktstellen für einen Kontakt mit den jeweiligen (Gegen-)Kontaktlaschen 7 des jeweils anderen Steckverbinders 1, 2 ausbilden.All conductors are made as stamped or stamped bending components, i. punched out of an electrically conductive sheet and then optionally formed, which allows a cost-effective mass production. All conductors also have sections in which these adjoin at least one side of the associated insulation bodies 5 and these are largely immovable. Furthermore, all conductors form contact areas 6, which are provided for contact with an associated contact area of the corresponding printed circuit board. In addition, contact lugs 7 are formed by the conductors, which form contact points for contact with the respective (counter) contact lugs 7 of the respective other connector 1, 2.

Die Innenleiter 3 des zweiten Steckverbinders 2 sind als einfache Stanzbauteile und somit mit einer besonders einfachen Geometrie ausgebildet. Diese bilden ebene, in einen freien Raum ragende Kontaktlaschen 7 mit relativ großen seitlichen Kontaktflächen aus. An den den Kontaktlaschen 7 entgegengesetzten Enden sind stirnseitig die Kontaktbereiche 6 für die Kontaktierung der entsprechenden Leiterplatte vorgesehen. Die Kontaktlaschen 7 des zweiten Steckverbinders 2 werden jeweils von mehreren (konkret drei) Kontaktfederlaschen 8 des ersten Steckverbinders 1 zangenartig kontaktiert. Die Kontaktfederlaschen 8 weisen dabei einen S-förmigen Verlauf auf. Dadurch wird zum einen ein relativ großer Federweg, d.h. eine Auslenkbarkeit in seitlicher Richtung erzielt. Zudem wird zwischen den drei Kontaktfederlaschen 8 eines Innenleiters 3 ein V-förmiger Einlauf ausgebildet, der das zangenartige Umgreifen der jeweiligen Kontaktlasche 7 des zweiten Steckverbinders 2 auch bei relativ großen Positionierungstoleranzen sicherstellt. Weiterhin werden durch den S-förmigen Verlauf relativ kleinflächige Kontaktstellen der Kontaktfederlaschen 8 ausgebildet. Die in dem Isolationskörper 5 des ersten Steckverbinders 1 befindlichen Abschnitte der Innenleiter 3 verlaufen eben und enden unterseitig in zwei um ca. 90° abgewinkelten Kontaktbereichen 6, mittels derer eine Kontaktierung der dazugehörigen Leiterplatte erfolgt.The inner conductors 3 of the second connector 2 are formed as simple stamping components and thus with a particularly simple geometry. These form flat, projecting into a free space contact tabs 7 with relatively large lateral contact surfaces. At the opposite ends of the contact tabs 7, the contact areas 6 are provided for the contacting of the corresponding printed circuit board. The contact tabs 7 of the second connector 2 are each of a plurality of (specifically three) contact spring tabs 8 of the first connector 1 contacted like a pliers. The contact spring tabs 8 have an S-shaped course. As a result, on the one hand a relatively large spring travel, ie a deflectability in the lateral direction achieved. In addition, a V-shaped inlet is formed between the three contact spring tabs 8 of an inner conductor 3, which ensures the pincer-like gripping the respective contact tab 7 of the second connector 2, even with relatively large positioning tolerances. Furthermore, relatively small-area contact points of the contact spring tabs 8 are formed by the S-shaped course. The located in the insulating body 5 of the first connector 1 sections of the inner conductor 3 are flat and ends at the bottom in two angled by about 90 ° contact areas 6, by means of which a contacting of the associated circuit board.

Die Außenleiter 4 beider Steckverbinder 1, 2 sind gehäuseförmig ausgebildet, wodurch diese die entsprechenden Innenleiter 3 umgeben und durch Umschließen von Abschnitten der Isolationskörper 5 mit diesen mechanisch verbunden sind.The outer conductor 4 of both connectors 1, 2 are formed housing-shaped, whereby they surround the corresponding inner conductor 3 and are mechanically connected by enclosing portions of the insulating body 5 with these.

Die Außenleiter 4 des zweiten Steckverbinders 2 ragen mit einem dreiseitigen Gehäuseabschnitt frei in den Raum, wobei die zwei sich gegenüberliegenden Seiten als Kontaktlaschen 7 dienen, die - wie bei den Innenleitern 3 - zangenartig von mehreren (konkret drei) S-förmigen Kontaktfederlaschen 8 des ersten Steckverbinders 1 kontaktiert werden.The outer conductor 4 of the second connector 2 protrude freely with a three-sided housing portion in the space, the two opposite sides serve as contact tabs 7 - like the inner conductors 3 - pliers like of several (concrete three) S-shaped contact spring tabs 8 of the first Connector 1 can be contacted.

Alle Kontaktlaschen 7 der zwei Steckverbinder 1, 2 sind relativ lang bzw. großflächig ausgebildet, wodurch diese - trotz hinreichender Stärke und somit Belastbarkeit - relativ weit bei den beim Zusammenstecken der Steckverbinder 1, 2 auftretenden Kräften seitlich ausgelenkt werden können. Diese relativ hohe Auslenkbarkeit addiert sich noch durch die besondere Ausgestaltung der Steckverbindung, bei der alle Kontaktelemente entsprechend elastisch auslenkbar ausgestaltet sind. Durch diese Flexibilität können die Toleranzanforderungen für die Steckverbinder 1, 2 gering gehalten werden, was wiederum deren Herstellung vereinfacht.All contact tabs 7 of the two connectors 1, 2 are formed relatively long or large area, whereby these - despite sufficient strength and thus load capacity - can be deflected relatively far at the forces occurring during mating of the connectors 1, 2 forces laterally. This relatively high deflectability is added by the special configuration of the connector, in which all contact elements are designed to be elastically deflectable. Due to this flexibility, the tolerance requirements for the connectors 1, 2 can be kept low, which in turn simplifies their manufacture.

Gleichzeitig ist durch die zangenförmige Kontaktierung der von den Innenleitern 3 des zweiten Steckverbinders 2 ausgebildeten Kontaktlaschen 7 durch die Kontaktfederlaschen 8 des ersten Steckverbinders 1 auch bei sehr großen Toleranzen stets ein ausreichender Kontaktdruck an zumindest einigen der Kontaktfederlaschen 8 und damit eine sichere Übertragung der Hochfrequenzsignale gewährleistet.At the same time, a sufficient contact pressure on at least some of the contact spring tabs 8 and thus a secure transmission of the high-frequency signals is always ensured by the tong-like contacting of the inner conductors 3 of the second connector 2 formed contact plates 7 by the contact spring tabs 8 of the first connector 1 even with very large tolerances.

Die besondere Ausgestaltung der Steckverbindung ermöglicht auch, relativ große Toleranzen in Richtung der Längsachsen der Innenleiter 3 des zweiten Steckverbinders 2 auszugleichen, da die seitlichen Kontaktflächen der von diesen ausgebildeten Kontaktlaschen 7 so groß sind, dass diese von den Kontaktfederlaschen 8 des ersten Steckverbinders in einem entsprechend großen Toleranzbereich kontaktieren werden können.The special configuration of the connector also makes it possible to compensate for relatively large tolerances in the direction of the longitudinal axes of the inner conductor 3 of the second connector 2, since the lateral contact surfaces of the trained by these contact tabs 7 are so large that these of the contact spring tabs 8 of the first connector in a corresponding large tolerance range can be contacted.

Die Isolationskörper 5 beider Steckverbinder 1, 2 sind einteilig aus Kunststoff hergestellt. Weiterhin sind diese so ausgeformt, dass ein Entformen auch aus einer zweiteiligen Form möglich ist. Hinterschnitte bezüglich der Entformungsrichtung (diese entspricht der Längsrichtung der Innenleiter 3 des zweiten Steckverbinders 2) sind vollständig oder weitgehend vermieden. Ein Spritzgießen der Isolationskörper 5 ist somit ohne größeren Aufwand möglich. Diese Herstellungsart ermöglicht ebenso wie das Stanzen bzw. Stanzbiegen aller Leiter eine besonders kostengünstige Herstellung aller Bauteile der Steckverbindung in einer Großserienfertigung.The insulation body 5 of both connectors 1, 2 are made in one piece from plastic. Furthermore, these are shaped so that a demoulding of a two-part mold is possible. Undercuts with respect to the Entformungsrichtung (this corresponds to the longitudinal direction of the inner conductor 3 of the second connector 2) are completely or largely avoided. An injection molding of the insulation body 5 is thus possible without much effort. This production method, like the stamping or punch bending of all conductors, enables a particularly cost-effective production of all components of the plug-in connection in mass production.

Hinzu kommt, dass auch die Montage sehr einfach und insbesondere automatisiert erfolgen kann. Hierzu müssen die bereits weitgehend vorgeformten Innenleiter 3 sowie die Außenleiter 4 des zweiten Steckverbinders 2 lediglich in die entsprechenden Durchgangsöffnungen der Isolationskörper 5 eingeschoben und dann fixiert werden. Bei den Innenleitern 3 des ersten Steckverbinders 1 und bei den Außenleitern 4 des zweiten Steckverbinders 2 werden hierzu die Kontaktbereiche 6 umgebogen. Bei den Innenleitern 3 des zweiten Steckverbinders 2 erfolgt die Fixierung stoffschlüssig durch Kleben. Selbstverständlich ist hier aber auch eine kraftschlüssig Fixierung oder eine formschlüssige Fixierung, beispielsweise durch Rastelemente, möglich. Dann werden noch die Außenleiter 4 des ersten Steckverbinders 1 auf die entsprechenden Abschnitte des Isolationskörpers 5 aufgeschoben und durch das Umbiegen von dann in Vertiefungen des Isolationskörpers 5 eingreifenden Verriegelungslaschen 9 fixiert.In addition, the assembly can be done very easily and in particular automated. For this purpose, the already largely preformed inner conductor 3 and the outer conductor 4 of the second connector 2 must be inserted only in the corresponding through holes of the insulation body 5 and then fixed. In the case of the inner conductors 3 of the first connector 1 and in the outer conductors 4 of the second connector 2, the contact regions 6 are bent over for this purpose. In the inner conductors 3 of the second connector 2, the fixation is made materially by gluing. Of course, here is also one non-positive fixation or a positive fixation, for example by locking elements, possible. Then the outer conductor 4 of the first connector 1 are pushed onto the corresponding portions of the insulating body 5 and fixed by the bending of then engaging in recesses of the insulating body 5 locking tabs 9.

Selbstverständlich kann anstelle von oder zusätzlich zu der formschlüssigen Fixierung durch Umbiegen von Laschen eine stoffschlüssige (z.B. durch Kleben) oder kraftschlüssig Fixierung vorgesehen sein. Auch kann eine formschlüssige Fixierung mittels Rastelementen vorgesehen sein.Of course, instead of or in addition to the positive fixing by bending tabs a cohesive (for example, by gluing) or frictionally fixing can be provided. Also, a positive fixation can be provided by means of locking elements.

Zum mechanischen Verbinden der Steckverbinder 1, 2 mit den entsprechenden Leiterplatten weisen beide Isolationskörper 5 Befestigungsstifte 10 auf, die durch entsprechende Durchgangsöffnungen der Leiterplatten hindurch gesteckt und durch plastische Verformung ihrer freien Enden fixiert werden können.For the mechanical connection of the connectors 1, 2 with the corresponding printed circuit boards, both insulation bodies 5 have fixing pins 10 which can be inserted through corresponding passage openings of the printed circuit boards and fixed by plastic deformation of their free ends.
