Description

Die Erfindung betrifft eine Kontaktvorrichtung mit mehreren Kontaktelementen zum elektrisch leitenden Verbinden von sich gegenüberliegenden Kontaktbereichen.
Derartige Kontaktelemente sollen eine möglichst verlustfreie Übertragung der Hochfrequenzsignale auch in einem definierten Toleranzbereich bezüglich der Parallelität sowie des (axialen) Abstands von zwei Leiterplatten sicherstellen. Auch ein radialer Versatz der Kontaktbereiche ist ggf. auszugleichen. Weitere Anforderungen an solche Kontaktelemente liegen in einer kostengünstigen Herstellung sowie ggf. einer einfachen Montage. Zudem sollen die axialen und radialen Abmessungen der Kontaktelemente möglichst klein sein.
The invention relates to a contact device with a plurality of contact elements for the electrically conductive connection of opposing contact areas.
Such contact elements are intended to ensure that the high-frequency signals are transmitted with as little loss as possible, even within a defined tolerance range with regard to parallelism and the (axial) distance between two circuit boards. A radial offset of the contact areas may also have to be compensated for. Further requirements for such contact elements are inexpensive production and possibly simple assembly. In addition, the axial and radial dimensions of the contact elements should be as small as possible.

Bekannt ist, eine 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 establish a connection between two circuit boards by means of two coaxial connectors firmly connected to the circuit boards and an adapter, the so-called "bullet", which connects the two coaxial connectors. This adapter enables an axial and radial tolerance compensation, as well as the compensation of parallelism tolerances. Typical coaxial connectors used for this are SMP, Mini-SMP or FMC.

Alternativ werden elektrische Verbindungen zwischen zwei Leiterplatten auch über Federkontaktstifte in Einzelleiter- und/oder Mehrfachleiteraufbau realisiert.Alternatively, electrical connections between two circuit boards are also implemented using spring contact pins in a single-conductor and / or multiple-conductor structure.

Aus der US 6,776,668 B1 ist weiterhin ein Koaxialkontaktelement bekannt, über das Hochfrequenzsignale zwischen zwei Leiterplatten übertragen werden sollen. Dabei dient ein Innenleiter, der in Form eines Federkontaktstifts ausgebildet ist, als Signalleiter, während ein den Innenleiter umgebender Außenleiter die Funktion eines Rückleiters sowie einer Schirmung für den Innenleiter aufweist. Der Außenleiter umfasst einen hülsenförmigen Grundkörper der in Längsrichtung mehrfach geschlitzt ist. Das nicht geschlitzte Ende des Grundkörpers bildet stirnseitig eine Kontaktstelle zur Kontaktierung eines Kontaktbereichs einer der Leiterplatten aus. Auf dem Grundkörper ist eine Hülse des Außenleiters verschiebbar geführt, die an einem Ende stirnseitig eine Kontaktstelle zur Kontaktierung eines Kontaktbereichs der anderen Leiterplatte ausbildet. Zwischen dem Grundkörper und der Hülse stützt sich eine vorgespannte Feder ab. Bei der Verbindung der beiden Leiterplatten, werden sowohl der Kopf des in Form eines Federkontaktstifts ausgebildeten Innenleiters als auch die Hülse des Außenleiters unter weiterer Vorspannung der jeweiligen Federn verschoben, wodurch trotz möglicher Toleranzen hinsichtlich des Abstands der Kontaktbereiche der Leiterplatten voneinander ein sicherer Kontaktdruck bereitgestellt werden kann. Durch die Schlitzung des Grundkörpers weist dieser zudem eine gewisse Flexibilität in seitlicher Richtung auf, wodurch erreicht werden soll, dass auch relativ große Nichtparallelitäten zwischen den beiden Kontaktbereichen ausgeglichen werden können.From the US 6,776,668 B1 a coaxial contact element is also known via which high-frequency signals are to be transmitted between two printed circuit boards. An inner conductor, which is designed in the form of a spring contact pin, serves as a signal conductor, while an outer conductor surrounding the inner conductor has the function of a return conductor and a shield for the inner conductor. The outer conductor comprises a sleeve-shaped base body which is slotted several times in the longitudinal direction. The end of the base body, which is not slotted, forms a contact point at the end for making contact with a contact area of one of the circuit boards. A sleeve of the outer conductor is displaceably guided on the base body and, at one end, forms a contact point for contacting a contact area of the other printed circuit board. A pretensioned spring is supported between the base body and the sleeve. When connecting the two circuit boards, both the head of the inner conductor in the form of a spring contact pin and the sleeve of the outer conductor are displaced under further preload of the respective springs, whereby a reliable contact pressure can be provided despite possible tolerances with regard to the distance between the contact areas of the circuit boards . Due to the slotting of the base body, it also has a certain flexibility in the lateral direction, which is intended to ensure that even relatively large non-parallelisms between the two contact areas can be compensated for.

Bekannt ist auch die Verwendung von einfachen Federlaschen als Kontaktelemente oder als Teil von Kontaktelementen. Diese weisen den Vorteil eines konstruktiv einfachen Aufbaus und einer kostengünstigen Herstellung als z.B. Stanzbiegebauteil auf. Gleichzeitig übernehmen Federlaschen integral die wesentlichen Funktionen derartiger Kontaktelemente, nämlich zum einen die Übertragung des Stroms bzw. der Signale sowie die elastische Deformation zur Erzielung eines ausreichenden Kontaktdrucks in den Kontaktstellen und zum Ausgleich von Lage- und Positionstoleranzen der zu verbindenden Bauteile. Nachteilig ist jedoch, dass Federlaschen prinzipbedingt bogenförmig oder abgewinkelt verlaufen müssen und die elektrisch zu verbindenden Kontaktbereiche somit nicht auf direktem Weg verbinden. Die relativ große Länge der Federlasche geht mit einer relativ großen Impedanz und auch Induktivität einher, die sich nachteilig insbesondere auf die Qualität der Übertragung von Hochfrequenzsignalen auswirken kann.
Aus der US 2007/0287315 A1 ist eine Kontaktvorrichtung mit einer Mehrzahl von Kontaktelementen bekannt, die über jeweils eine erste und eine zweite Kontaktstelle eines Außenleiters der Kontaktvorrichtung elektrisch verbunden werden, wobei die erste und die zweite Kontaktstelle zum Kontaktieren von Kontaktbereichen von Bauteilen vorgesehen sind. Die Kontaktelemente weisen jeweils einen ersten Abschnitt auf, der die Kontaktstellen elektrisch verbindet und der zumindest teilweise die Form einer Federlasche aufweist. Ferner weisen die Kontaktelemente zweite Abschnitte mit zwei Teilabschnitten auf, die zumindest abschnittsweise von einem gemeinsamen Leiter ausgebildet werden, die ebenfalls die erste und zweite Kontaktstelle elektrisch verbinden. Dabei bildet der erste Abschnitt einen ersten Verbindungspfad und die beiden Teilabschnitte bilden einen zweiten Verbindungspfad, wobei der zweite Verbindungspfad kürzer als der erste Verbindungspfad ist.
Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, eine verbesserte Kontaktvorrichtung zum elektrischen Verbinden von Bauteilen anzugeben. Insbesondere sollte sich das Verbindungselement durch eine gute Hochfrequenzsignalübertragung, Toleranzen ausgleichende Eigenschaften und/oder eine kostengünstige Herstellung auszeichnen. Diese Aufgabe wird durch eine Kontaktvorrichtung gemäß dem unabhängigen Anspruch gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Kontaktvorrichtung sind Gegenstand der abhängigen Ansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.
The use of simple spring tabs as contact elements or as part of contact elements is also known. These have the advantage of a structurally simple structure and cost-effective production as, for example, a stamped and bent component. At the same time, spring tabs take over the essential functions of such contact elements integrally, namely on the one hand the transmission of the current or the signals and the elastic deformation to achieve a sufficient Contact pressure in the contact points and to compensate for positional and positional tolerances of the components to be connected. However, it is disadvantageous that spring tabs have to run in a curved or angled manner due to the principle involved and thus do not connect the contact areas to be electrically connected in a direct way. The relatively large length of the spring clip is associated with a relatively large impedance and also inductance, which can have a disadvantageous effect, in particular on the quality of the transmission of high-frequency signals.
From the US 2007/0287315 A1 a contact device with a plurality of contact elements is known which are electrically connected via a first and a second contact point of an outer conductor of the contact device, the first and the second contact point being provided for contacting contact areas of components. The contact elements each have a first section which electrically connects the contact points and which at least partially has the shape of a spring tab. Furthermore, the contact elements have second sections with two partial sections, which are formed at least in sections by a common conductor, which also electrically connect the first and second contact points. The first section forms a first connection path and the two subsections form a second connection path, the second connection path being shorter than the first connection path.
Proceeding from this prior art, the invention was based on the object of specifying an improved contact device for electrically connecting components. In particular, the connecting element should be distinguished by good high-frequency signal transmission, properties that compensate for tolerances and / or inexpensive manufacture. This object is achieved by a contact device according to the independent claim. Advantageous configurations of the contact device according to the invention are the subject matter of the dependent claims and result from the following Description of the invention.

Der vorliegenden Anmeldung liegt der Gedanke zugrunde, ein in Form einer Federlasche ausgebildetes Kontaktelement dadurch zu verbessern, dass ein zusätzlicher - neben dem Verbindungspfad über die Federlasche selbst - Verbindungspfad vorgesehen wird, der die Kontaktbereiche der elektrisch zu verbindenden Bauteile auf möglichst direktem Weg verbindet und daher eine möglichst kurze Länge aufweist.The present application is based on the idea of improving a contact element designed in the form of a spring tab by providing an additional connection path, in addition to the connection path via the spring tab itself, which connects the contact areas of the components to be electrically connected as directly as possible and therefore has the shortest possible length.

Ein Kontaktelement zum elektrisch leitenden Verbinden von Bauteilen weist demnach Kontaktstellen zum Kontaktieren dieser Kontaktbereiche auf und umfasst weiterhin einen ersten, die Kontaktstellen elektrisch verbindenden Abschnitt, der zumindest teilweise in Form einer Federlasche ausgebildet ist. Weiterhin ist ein zweiter, die Kontaktstellen elektrisch verbindender Abschnitt vorgesehen, wobei der von diesem ausgebildete Verbindungspfad kürzer als derjenige des ersten Abschnitts ist.A contact element for the electrically conductive connection of components accordingly has contact points for contacting these contact areas and furthermore comprises a first, the contact points electrically connecting portion which is at least partially in the form of a spring tab. Furthermore, a second section is provided which electrically connects the contact points, the connection path formed by this being shorter than that of the first section.

Unter "Federlasche" wird erfindungsgemäß ein vorzugsweise flächiges Bauteil (mit einer Höhe, die nur einen Bruchteil der Breite und der Länge beträgt, wobei die Breite vorzugsweise zudem nur ein Bruchteil der Länge beträgt) verstanden, das sich von einer Anbindungsstelle, in der dieses fest mit einem anderen Bauteil verbunden ist, in einen freien Raum erstreckt, wobei das Bauteil bei Druck auf die von der Länge und der Breite aufgespannten Fläche elastisch ausgelenkt wird und dadurch eine funktionale Federwirkung bereitstellt.According to the invention, "spring tab" is understood to mean a preferably flat component (with a height that is only a fraction of the width and length, the width preferably also only a fraction of the length) that extends from a connection point in which it is fixed is connected to another component, extends into a free space, wherein the component is elastically deflected when pressure is applied to the surface spanned by the length and width and thereby provides a functional spring effect.

Durch die erfindungsgemäße Ausgestaltung eines Kontaktelements wird ein Verbindungspfad geschaffen, der kurz ist und sich daher durch eine geringe Impedanz auszeichnet. Auch ist die Induktivität des Kontaktelements vergleichsweise gering, was einen positiven Einfluss auf die Übertragung von Hochfrequenzsignalen hat.The configuration of a contact element according to the invention creates a connection path which is short and is therefore characterized by a low impedance. The inductance of the contact element is also comparatively low, which has a positive influence on the transmission of high-frequency signals.

Trotz dieser guten elektrischen Eigenschaften kann sich das Kontaktelement durch einen äußerst einfachen Aufbau und eine kostengünstige Herstellbarkeit, insbesondere als Stanzbiegebauteil, auszeichnen. Dies gilt insbesondere dann, wenn, wie in einer bevorzugten Ausgestaltung vorgesehen, der erste Abschnitt und der zweite Abschnitt des Kontaktelements integral in Form einer Federlasche ausgebildet sind. Das Kontaktelement kann somit in Form einer einzelnen Federlasche ausgebildet sein, die infolge ihrer Formgebung einen ersten Abschnitt aufweist, der primär durch eine elastische Deformation den Kontaktdruck in den Kontaktstellen sowie einen Toleranzausgleich sicherstellt, während ein zweiter, kürzerer Abschnitt primär der Strom- oder Signalübertragung dient.Despite these good electrical properties, the contact element can have an extremely simple structure and an inexpensive one Manufacture, especially as a stamped and bent component. This applies in particular when, as provided in a preferred embodiment, the first section and the second section of the contact element are designed integrally in the form of a spring tab. The contact element can thus be designed in the form of a single spring tab which, due to its shape, has a first section that primarily ensures the contact pressure in the contact points and tolerance compensation through elastic deformation, while a second, shorter section is primarily used for power or signal transmission .

Eine Relativbewegung der Kontaktstellen des Kontaktelements infolge einer elastischen Deformation des ersten Abschnitts muss von dem zweiten Abschnitt ausgeglichen werden können. Dies kann durch eine entsprechende elastische Deformation des zweiten Abschnitts erfolgen. Vorzugsweise vorgesehen ist jedoch, dass der zweite Abschnitt Teilabschnitte umfasst, die bei einer Deformation des ersten Abschnitts aneinander abgleiten. Diese Ausgestaltung kann den Vorteil haben, dass sich die Länge des Verbindungspfads stets an den tatsächlichen Abstand der Kontaktstellen anpasst.A relative movement of the contact points of the contact element as a result of an elastic deformation of the first section must be able to be compensated for by the second section. This can be done by a corresponding elastic deformation of the second section. However, it is preferably provided that the second section comprises subsections which slide off one another when the first section is deformed. This configuration can have the advantage that the length of the connection path always adapts to the actual distance between the contact points.

Eine erfindungsgemäße Kontaktvorrichtung ist dadurch gekennzeichnet, dass diese eine Mehrzahl von Kontaktelementen umfasst.A contact device according to the invention is characterized in that it comprises a plurality of contact elements.

Die Kontaktelemente sind dabei derart angeordnet, dass deren erste Abschnitte deren zweite Abschnitte (zumindest abschnittsweise) ringförmig umgeben. Dadurch kann ein guter Kontakt von vergleichsweise großen Kontaktbereichen der zu kontaktierenden Bauteile gewährleistet werden. Da dabei zudem jede Kontaktstelle durch eine entsprechende Deformation des dazugehörigen ersten Abschnitts individuell ausweichen kann, können durch eine solche Kontaktvorrichtung auch vergleichsweise große Toleranzen (insbesondere hinsichtlich der Parallelität) der zu verbindenden Kontaktbereiche ausgeglichen werden.The contact elements are arranged such that their first sections surround their second sections (at least in sections) in an annular manner. In this way, a good contact of comparatively large contact areas of the components to be contacted can be guaranteed. Since each contact point can also evade individually by a corresponding deformation of the associated first section, comparatively large tolerances (in particular with regard to parallelism) of the contact areas to be connected can also be compensated for by such a contact device.

Bei einer Ausgestaltung der Kontaktvorrichtung als Koaxialkontaktvorrichtung, bei der die Kontaktelemente einen Außenleiter ausbilden, der einen Innenleiter umgibt, kann durch eine (vorzugsweise kreis-) ringförmige Anordnung der ersten Abschnitte der Kontaktelemente eine Abschirmung für den Innenleiter ausgebildet werden.In an embodiment of the contact device as Coaxial contact device, in which the contact elements form an outer conductor which surrounds an inner conductor, a shield for the inner conductor can be formed by a (preferably circular) annular arrangement of the first sections of the contact elements.

Insbesondere zur weiteren Verbesserung der Schirmwirkung durch die ersten Abschnitte der Kontaktelemente kann weiterhin vorgesehen sein, dass diese doppelringförmig um die zweiten Abschnitte herum angeordnet sind und dadurch in gewisser Weise einen Doppelschirm ausbilden. Demnach würden die ersten Abschnitte einer ersten Teilmenge der Kontaktelemente die zweiten Abschnitte der Kontaktelemente ringförmig umgeben und die ersten Abschnitte einer zweiten Teilmenge der Kontaktelemente die ersten Abschnitte der ersten Teilmenge ringförmig umgeben.In particular, to further improve the shielding effect through the first sections of the contact elements, it can furthermore be provided that these are arranged in a double-ring shape around the second sections and thereby form a double shield in a certain way. Accordingly, the first sections of a first subset of the contact elements would surround the second sections of the contact elements in a ring and the first sections of a second subset of the contact elements would surround the first sections of the first subset in a ring.

Vorzugsweise können dabei die (weiterhin bevorzugt jeweils in gleichmäßiger Teilung angeordneten) ersten Abschnitte des einen Rings rotatorisch (vorzugsweise um eine halbe Teilung) zu den ersten Abschnitten des zweiten Rings versetzt sein, so dass die zwischen den ersten Abschnitten eines Rings ausgebildeten Lücken (aus Sicht der zweiten Abschnitte) von den ersten Abschnitten des anderen Rings (zumindest teilweise) verdeckt sind.Preferably, the first sections of one ring (preferably each arranged in a uniform pitch) can be rotatably offset (preferably by half a pitch) to the first sections of the second ring, so that the gaps formed between the first sections of a ring (from of the second sections) are (at least partially) covered by the first sections of the other ring.

Es ist vorgesehen, dass die zweiten Abschnitte der Kontaktelemente zumindest abschnittsweise von einem gemeinsamen Leiter ausgebildet sind. Dies kann insbesondere fertigungs- und montagetechnische Vorteile aufweisen.It is provided that the second sections of the contact elements are formed at least in sections by a common conductor. This can have advantages in terms of production and assembly in particular.

Dabei kann weiterhin vorgesehen sein, dass der gemeinsame Leiter starr ausgebildet ist und an einem ersten (längsaxialen) Ende eine Kontaktstelle für einen Kontakt mit einem ersten der Kontaktbereiche ausbildet und an dem gemeinsamen Leiter die zweiten Abschnitte der Kontaktelemente in Form von Federlaschen befestigt sind. Die Federlaschen bilden dann vorzugsweise die Kontaktstellen für den Kontakt mit (mindestens) einem zweiten Kontaktbereich aus.It can also be provided that the common conductor is rigid and at a first (longitudinally axial) end forms a contact point for contact with a first of the contact areas and the second sections of the contact elements are attached to the common conductor in the form of spring tabs. The spring tabs then preferably form the contact points for contact with (at least) one second contact area.

Dabei kann weiterhin vorgesehen sein, dass die ersten Abschnitte der Kontaktelemente ein zweites (längsaxiales) Ende des gemeinsamen Leiters überragen, wobei die Kontaktstellen weiterhin bevorzugt von den überragenden Abschnitten der Federlaschen ausgebildet werden. Dadurch wird bei einer in einer Ebene liegenden, von den Kontaktstellen der Federlaschen zu kontaktierenden Kontaktfläche sichergestellt, dass ein ausreichender Deformationsweg für die Federlaschen bereitgestellt wird und ein Kontakt des entsprechenden zweiten längsaxialen Endes des gemeinsamen Leiters mit dem Kontaktbereich vermieden wird.It can further be provided that the first sections of the contact elements protrude beyond a second (longitudinally axial) end of the common conductor, the contact points furthermore preferably being formed by the protruding sections of the spring tabs. With a contact surface lying in one plane and to be contacted by the contact points of the spring tabs, this ensures that a sufficient deformation path is provided for the spring tabs and contact of the corresponding second longitudinal axial end of the common conductor with the contact area is avoided.

In einer weiterhin bevorzugten Ausgestaltung der erfindungsgemäßen Kontaktvorrichtung kann vorgesehen sein, dass die Federlaschen an (mindestens) einem Abschnitt des gemeinsamen Leiters relativbeweglich und unter Federbelastung anliegen.In a further preferred embodiment of the contact device according to the invention, it can be provided that the spring tabs rest on (at least) one section of the common conductor in a relatively movable manner and under spring loading.

In einer Ausführungsform der Federlaschen kann zudem vorgesehen sein, dass deren freie Enden in Richtung des ersten Endes des gemeinsamen Leiters weisen (und somit in Richtung desjenigen Endes des gemeinsamen Leiter, an dem diese an diesem befestigt sind) und mittlere Abschnitte der Federlaschen die Kontaktstellen ausbilden. Dann kann weiterhin bevorzugt vorgesehen sein, dass die Federlaschen im Bereich ihrer freien Enden an dem gemeinsamen Leiter anliegen.In one embodiment of the spring tabs it can also be provided that their free ends point in the direction of the first end of the common conductor (and thus in the direction of that end of the common conductor to which they are attached) and middle sections of the spring tabs form the contact points . Then it can furthermore preferably be provided that the spring tabs bear against the common conductor in the region of their free ends.

In einer alternativen Ausführungsform der Federlaschen kann vorgesehen sein, dass die freien Enden der Federlaschen in Richtung des zweiten Endes weisen und im Bereich der freien Enden die Kontaktstellen zur Kontaktierung des dazugehörigen Kontaktbereichs ausbilden. Dann kann weiterhin vorgesehen sein, dass mittlere Abschnitte der Federlaschen an dem gemeinsamen Leiter anliegen.In an alternative embodiment of the spring tabs it can be provided that the free ends of the spring tabs point in the direction of the second end and in the area of the free ends form the contact points for making contact with the associated contact area. Then it can also be provided that middle sections of the spring tabs rest on the common conductor.

Selbstverständlich besteht die Möglichkeit, beide dieser Ausführungsformen der Federlaschen in einer erfindungsgemäßen Kontaktvorrichtung zu kombinieren.There is of course the possibility of using both of these embodiments of the spring tabs in a contact device according to the invention combine.

Zur Vereinfachung der Herstellbarkeit eines erfindungsgemäßen Kontaktelements oder einer erfindungsgemäßen Kontaktvorrichtung kann vorgesehen sein, dass die Federlaschen der Kontaktelemente zwei seitlich versetzte, sich in einem längsaxialen Abschnitt überlappende und dort (vorzugsweise einstückig) verbundene Federläschenabschnitte umfassen. Dies vereinfacht insbesondere den Einsatz eines Biegewerkzeugs bei der Herstellung eines die Federlaschen ausbildenden Federlaschenkorbs als Stanzbiegebauteil.To simplify the producibility of a contact element according to the invention or a contact device according to the invention it can be provided that the spring tabs of the contact elements comprise two laterally offset spring tab sections that overlap in a longitudinal axial section and are connected there (preferably in one piece). This in particular simplifies the use of a bending tool in the production of a spring tab cage forming the spring tabs as a stamped and bent component.

Die erfindungsgemäße Kontaktvorrichtung ist vorzugsweise als Koaxialkontaktvorrichtung mit einem Innenleiter und einem den Innenleiter umgebenden Außenleiter ausgebildet. Dabei ist besonders bevorzugt vorgesehen, dass der Außenleiter erfindungsgemäß ausgebildet ist, während weiterhin bevorzugt der Innenleiter als Federkontaktstift ausgebildet sein kann.The contact device according to the invention is preferably designed as a coaxial contact device with an inner conductor and an outer conductor surrounding the inner conductor. It is particularly preferably provided that the outer conductor is designed according to the invention, while the inner conductor can furthermore preferably be designed as a spring contact pin.

Das Kontaktelement und die erfindungsgemäße Kontaktvorrichtung können vorteilhafterweise zur Übertragung von Hochfrequenzsignalen zwischen Bauteilen und insbesondere Leiterplatten verwendet werden, wobei bei einer Ausgestaltung als Koaxialkontaktvorrichtung vorzugsweise der Innenleiter als Signalleiter und der Außenleiter als Rückleiter und/oder Schirmung genutzt wird.The contact element and the contact device according to the invention can advantageously be used for the transmission of high-frequency signals between components and in particular circuit boards, with the inner conductor being used as the signal conductor and the outer conductor as the return conductor and / or shielding in a configuration as a coaxial contact device.

Das in den Fig. 1 bis 5 dargestellte Kontaktelement ist einteilig in Form einer Federlasche 11 aus elektrisch leitendem Werkstoff (insbesondere einem Metall) ausgebildet. Das Kontaktelement bildet zwei Kontaktstellen 17 aus, die für einen Kontakt mit Kontaktbereichen von zwei elektrisch über eines oder mehrere der Kontaktelemente zu verbindenden Bauteile, insbesondere Leiterplatten, vorgesehen sind. Eine der Kontaktstellen 17 (die untere in den Fig. 1 bis 5) ist vergleichsweise großflächig ausgebildet. Über diese Kontaktstelle 17 soll das Kontaktelement fest mit dem dazugehörigen Kontaktbereich eines Bauteils verbunden, insbesondere verlötet werden. Die zweite Kontaktstelle 17, die eher punkt- oder linienförmig ausgebildet ist, soll den dazugehörigen Kontaktbereich eines Bauteils dagegen frei kontaktieren, d.h. lediglich unter einem durch eine elastische Deformation des Kontaktelements ausgeübten Kontaktdruck.That in the Figs. 1 to 5 The contact element shown is designed in one piece in the form of a spring tab 11 made of electrically conductive material (in particular a metal). The contact element forms two contact points 17, which are provided for contact with contact areas of two components, in particular printed circuit boards, to be connected electrically via one or more of the contact elements. One of the contact points 17 (the lower one in the Figs. 1 to 5 ) is designed to be comparatively large. About these Contact point 17, the contact element is intended to be firmly connected to the associated contact area of a component, in particular to be soldered. The second contact point 17, which is more punctiform or linear, is intended to make free contact with the associated contact area of a component, ie, only under a contact pressure exerted by an elastic deformation of the contact element.

Ein erster, die zwei Kontaktstellen 17 elektrisch verbindender Abschnitt des Kontaktelements ist primär für die Erzeugung des Kontaktdrucks zuständig. Ein Aufeinanderzubewegen der Kontaktstellen führt zu einer elastischen Deformation dieses ersten Abschnitts, wie dies insbesondere in der Fig. 5 zu erkennen ist.A first section of the contact element that electrically connects the two contact points 17 is primarily responsible for generating the contact pressure. Moving the contact points towards one another leads to an elastic deformation of this first section, as in particular in FIG Fig. 5 can be seen.

Ein zweiter Abschnitt umfasst zwei Teilabschnitte, von denen jeder eines der freien Enden der Federlasche 11 umfasst. Nach einer ersten, vergleichsweise kleinen Deformation des ersten Abschnitts kontaktieren die beiden Teilabschnitte und verbinden somit die beiden Kontaktstellen 17 ebenfalls elektrisch miteinander. Hierdurch wird ein primärer Pfad für die über das Kontaktelement zu übertragenden Hochfrequenzsignale geschaffen, der deutlich kürzer als derjenige Pfad ist, der von dem ersten Abschnitt ausgebildet ist. Bei einer weiteren Deformation des ersten Abschnitts gleiten die beiden Teilabschnitte aneinander ab. Dabei verringert sich die Länge des Verbindungspfads.A second section comprises two sub-sections, each of which comprises one of the free ends of the spring tab 11. After a first, comparatively small deformation of the first section, the two subsections make contact and thus also electrically connect the two contact points 17 to one another. This creates a primary path for the high-frequency signals to be transmitted via the contact element, which path is significantly shorter than that path formed by the first section. In the event of a further deformation of the first section, the two subsections slide off one another. This reduces the length of the connection path.

Die in den Fig. 6 bis 11 dargestellten Kontaktvorrichtungen umfassen jeweils einen Innenleiter 1, einen Außenleiter 2 sowie ein zwischen dem Innenleiter 1 und dem Außenleiter 2 angeordnetes Isolationselement 3.The ones in the Figures 6 to 11 The contact devices shown each include an inner conductor 1, an outer conductor 2 and an insulation element 3 arranged between the inner conductor 1 and the outer conductor 2.

Der Innenleiter 1 ist jeweils in Form eines Federkontaktstifts ausgebildet, d.h. dieser umfasst eine elektrisch leitende Hülse 4 sowie einen teilweise innerhalb der Hülse 4 beweglich geführten, elektrisch leitenden Kopf 5 mit sphärischer Kontaktfläche. Innerhalb der Hülse 4 ist eine Feder 6 angeordnet, die sich zwischen dem Kopf 5 und dem Grund der Hülse 4 abstützt. Der Innenleiter 1 ist unbeweglich innerhalb einer Aufnahmeöffnung des Isolationselements 3 gelagert. Dabei kann der Innenleiter 1 insbesondere stoffschlüssig, z.B. durch Verkleben, mit dem Isolationskörper 3 verbunden sein. Die dem Kopf 5 abgewandte Bodenseite der Hülse 4 bildet eine Kontaktfläche aus, die als Kontaktstelle 17 zur Kontaktierung eines Kontaktbereichs einer (nicht dargestellten) Basisleiterplatte dientThe inner conductor 1 is designed in the form of a spring contact pin, ie it comprises an electrically conductive sleeve 4 and an electrically conductive head 5 with a spherical contact surface, which is partially movably guided within the sleeve 4. A spring 6 is arranged inside the sleeve 4 and is supported between the head 5 and the base of the sleeve 4. The inner conductor 1 is immovable within a receiving opening of the insulation element 3 stored. The inner conductor 1 can in particular be connected to the insulation body 3 in a materially bonded manner, for example by gluing. The bottom side of the sleeve 4 facing away from the head 5 forms a contact surface which serves as a contact point 17 for contacting a contact area of a base circuit board (not shown)

Der Außenleiter 2 besteht prinzipiell aus einer Mehrzahl von erfindungsgemäßen Kontaktelementen und umfasst einen gemeinsamen Leiter 7, der die Mantelfläche des Isolationskörpers 3 vollständig und dessen Stirnflächen teilweise umgibt. Dadurch ist auch der gemeinsame Leiter 7 unbeweglich mit dem Isolationselement 3 verbunden. Neben dieser Möglichkeit einer formschlüssigen Verbindung kann alternativ oder zusätzlich auch eine kraft- oder stoffschlüssige Verbindung vorgesehen sein.The outer conductor 2 consists in principle of a plurality of contact elements according to the invention and comprises a common conductor 7, which completely surrounds the jacket surface of the insulation body 3 and partially surrounds its end faces. As a result, the common conductor 7 is also immovably connected to the insulation element 3. In addition to this possibility of a positive connection, alternatively or additionally a non-positive or material connection can also be provided.

Der gemeinsame Leiter 7 umfasst ein Bodenteil 8 sowie ein damit fest (insbesondere stoffschlüssig durch z.B. Löten oder Schweißen) verbundenes Hülsenteil 9.The common conductor 7 comprises a bottom part 8 as well as a sleeve part 9 firmly connected to it (in particular in a materially bonded manner by, for example, soldering or welding).

Das Bodenteil 8 bildet auf der dem Isolationskörper 3 abgewandten Seite eine Kontaktfläche aus, die als Kontaktstelle 17 zur Kontaktierung eines Kontaktbereichs einer Basisleiterplatte dient.On the side facing away from the insulation body 3, the bottom part 8 forms a contact surface which serves as a contact point 17 for contacting a contact area of a base circuit board.

Das mit dem Bodenteil 8 verbundene Ende des Hülsenteils 9 umfasst einen umlaufenden Vorsprung 10, an dem ein elektrisch leitender Federlaschenkorb (vorzugsweise stoffschlüssig, insbesondere durch Löten) befestigt ist. Der Federlaschenkorb bildet eine Mehrzahl von (konkret acht) Federlaschen 11 aus, die sich ausgehend von einem ringförmigen, radial bezüglich des Hülsenteils 9 ausgerichteten Abschnitt 12, über den der Federlaschenkorb mit dem gemeinsamen Leiter 7 verbunden ist, in gleichmäßiger Teilung über dem Umfang dieses ringförmigen Abschnitts 12 verteilt, bogenförmig in Längsrichtung der Kontaktvorrichtung erstrecken.The end of the sleeve part 9 connected to the base part 8 comprises a circumferential projection 10 to which an electrically conductive spring tab cage is attached (preferably in a materially bonded manner, in particular by soldering). The spring tab cage forms a plurality of (specifically eight) spring tabs 11 which, starting from an annular section 12, which is aligned radially with respect to the sleeve part 9 and via which the spring tab cage is connected to the common conductor 7, are evenly spaced over the circumference of this annular Section 12 distributed, extend arcuately in the longitudinal direction of the contact device.

Die drei in den Fig. 6 bis 11 dargestellten Ausführungsformen erfindungsgemäßer Kontaktvorrichtungen unterscheiden sich hinsichtlich der Form ihrer Federlaschen 11 sowie der Position der von diesen ausgebildeten Kontaktstellen 17.The three in the Figures 6 to 11 illustrated embodiments of contact devices according to the invention differ with regard to the Shape of their spring tabs 11 and the position of the contact points 17 formed by them.

Bei der Ausführungsform gemäß den Fig. 6 und 7 verlaufen die Federlaschen 11 - beginnend am äußeren Rand des ringförmigen Abschnitts 12 - jeweils in einem nahezu halbkreisförmigen Bogen, der in eine Abwinkelung von ca. 90° übergeht. In den sich daran anschließenden Abschnitten der Federlaschen 11, in denen diese den gemeinsamen Leiter 7 bereits überragen, verlaufen diese annähernd parallel. Die freien Enden der Federlaschen 11 sind schließlich noch nach außen gebogen ausbildet. Diese gebogenen Enden bilden Kontaktstellen 17 aus, mit denen der Außenleiter 2 einen ebenen, im Wesentlichen senkrecht zur Längsachse der Kontaktvorrichtung ausgerichteten Kontaktbereich einer (nicht dargestellten) Zielleiterplatte kontaktieren kann.In the embodiment according to Figures 6 and 7 the spring tabs 11 - beginning at the outer edge of the annular section 12 - each run in an almost semicircular arc that merges into an angled portion of approximately 90 °. In the adjoining sections of the spring tabs 11, in which they already protrude beyond the common conductor 7, they run approximately parallel. The free ends of the spring tabs 11 are finally formed bent outwards. These bent ends form contact points 17 with which the outer conductor 2 can contact a flat contact area of a target circuit board (not shown) that is oriented essentially perpendicular to the longitudinal axis of the contact device.

In den parallel zueinander verlaufenden Abschnitten der Federlaschen 11 liegen diese an einem umlaufenden Vorsprung 13 (mit halbkreisförmigem Querschnitt) des Hülsenteils 9 des gemeinsamen Leiters 7 an. Dieses Anliegen erfolgt unter Federbelastung, die durch die Federlaschen 11 selbst aufgebracht wird.In the sections of the spring tabs 11 that run parallel to one another, they rest against a circumferential projection 13 (with a semicircular cross section) of the sleeve part 9 of the common conductor 7. This concern takes place under spring loading, which is applied by the spring tabs 11 themselves.

Bei der Ausführungsform gemäß den Fig. 8 und 9 verlaufen die Federlaschen 11 - beginnend am äußeren Rand des ringförmigen Abschnitts 12 - zunächst in einem 90°-Bogen und gehen dann in einen Abschnitt über, in dem diese nahezu parallel verlaufen. Dieser Abschnitt geht, ungefähr in Höhe des oberen Endes des gemeinsamen Leiters 7, in einen 180°-Bogen über. Die Kontaktstellen 17, mit denen der Außenleiter 2 einen Kontaktbereich der Zielleiterplatte kontaktieren kann, sind ca. mittig des den 180°-Bogen ausbildenden Abschnitts gelegen. Ein Anliegen der Federlaschen 11 unter Federbelastung an dem gemeinsamen Leiter 7 erfolgt im Bereich bzw. in der Nähe ihrer freien Enden.In the embodiment according to Figures 8 and 9 the spring tabs 11 - beginning at the outer edge of the annular section 12 - initially run in a 90 ° bend and then merge into a section in which they run almost parallel. This section merges into a 180 ° bend approximately at the level of the upper end of the common conductor 7. The contact points 17 with which the outer conductor 2 can contact a contact area of the target circuit board are located approximately in the center of the section forming the 180 ° bend. The spring tabs 11 bear against the common conductor 7 under spring loading in the area or in the vicinity of their free ends.

Bei der Ausführungsform gemäß den Fig. 10 und 11 verlaufen die Federlaschen 11 ähnlich zu denjenigen der Ausführungsform gemäß den Fig. 8 und 9, wobei jedoch kein mittiger Abschnitt vorgesehen ist, in dem diese annähernd parallel ausgerichtet sind. Vielmehr verlaufen die Federlaschen 11 - beginnend am äußeren Rand des ringförmigen Abschnitts 12 - in einem Bogen mit mehr oder weniger kontinuierlicher Krümmung, der sich über annähernd 270° erstreckt.In the embodiment according to Figures 10 and 11 run the spring tabs 11 similar to those of the embodiment according to FIG Figures 8 and 9 , but no central section is provided in which they are aligned approximately parallel. Rather, the spring tabs 11 - beginning at the outer edge of the annular section 12 - run in an arc with a more or less continuous curvature which extends over approximately 270 °.

Weiterhin unterscheiden sich die Federlaschen 11 der Ausführungsform gemäß den Fig. 10 und 11 noch in ihrer Flächenform von denjenigen der Ausführungsform gemäß den Fig. 8 und 9. Während die letztgenannten jeweils aus einem einzelnen gebogenen Streifen mit im Wesentlichen konstanter Breite ausgebildet sind, weisen die Federlaschen 11 der Kontaktvorrichtung gemäß den Fig. 10 und 11 eine Flächenform auf, bei der zwei gebogene Teilstreifen seitlich versetzt angeordnet sind, die sich zudem in einem längsaxialen Abschnitt überlappen, wo diese einstückig miteinander verbunden sind. Diese Ausführungsform kann die Herstellung des Federlaschenkorbs als Stanzbiegebauteil vereinfachen, da durch den seitlichen Versatz jeweils Platz für das Hineinfahren eines Biegewerkzeugs zum Bearbeiten eines der Teilstreifen geschaffen wird.Furthermore, the spring tabs 11 of the embodiment according to FIGS Figures 10 and 11 nor in their surface shape from those of the embodiment according to FIGS Figures 8 and 9 . While the latter are each formed from a single curved strip with a substantially constant width, the spring tabs 11 of the contact device according to FIGS Figures 10 and 11 a surface shape in which two curved partial strips are arranged laterally offset, which also overlap in a longitudinal axial section, where they are integrally connected to one another. This embodiment can simplify the production of the spring clip cage as a stamped and bent component, since the lateral offset creates space for a bending tool to be inserted in order to process one of the partial strips.

Die in den Fig. 12 und 13 dargestellte Kontaktvorrichtung weist Federlaschen 11 auf, die hinsichtlich ihres Verlaufs im Wesentlichen denjenigen der Kontaktvorrichtung der Fig. 8 und 9 entsprechen. Wesentlicher Unterschied dieser Kontaktvorrichtung zu denjenigen der Fig. 6 bis 11 ist die Verbindung des gemeinsamen Leiters 7 mit einem Anschlussleiter 14, der eine Mutter 15 sowie ein Außengewinde 16 ausbildet. Über dieses Außengewinde 16 kann die Kontaktvorrichtung in einer Öffnung eines Gehäuses (nicht dargestellt) fixiert werden. Die Hülse 4 des Innenleiters 1 ist entsprechend verlängert ausgebildet und überragt das freie Ende des Anschlussleiters 14.The ones in the Figures 12 and 13 The contact device shown has spring tabs 11 which, in terms of their course, are essentially that of the contact device of Figures 8 and 9 correspond. Essential difference between this contact device and those of the Figures 6 to 11 is the connection of the common conductor 7 with a connection conductor 14, which forms a nut 15 and an external thread 16. The contact device can be fixed in an opening of a housing (not shown) via this external thread 16. The sleeve 4 of the inner conductor 1 is designed to be correspondingly elongated and projects beyond the free end of the connection conductor 14.

Bei den in den Fig. 6 bis 13 dargestellten Kontaktvorrichtungen bilden die Federlaschen 11 jeweils einen Teil eines ersten Abschnitts eines erfindungsgemäßen Kontaktelements aus. Über diese werden die zwei Kontaktstellen 17 des Außenleiters 2 der Kontaktvorrichtung elektrisch verbunden, wobei die primäre Funktion die Erzeugung eines Kontaktdrucks in den oberen Kontaktstellen und der Ausgleich von Toleranzen bezüglich der Lage und Ausrichtung der Kontaktbereiche der zu verbindenden Bauteile ist. Da die untere Kontaktstelle 17 von der Unterseite des Bodenteils 8 (bzw. von dem Anschlussleiter 14 bei der Kontaktvorrichtung gemäß den Fig. 12 und 13) ausgebildet ist, ist das Bodenteil 8 (bzw. der Anschlussleiter 14), ein Teil des Hülsenteils 9 sowie der ringförmige Abschnitt 12 ebenfalls Teil des ersten Abschnitts jedes der Kontaktelemente. Ein zweiter, primär der elektrischen Verbindung dienender Abschnitt der einzelnen Kontaktelemente wird durch den gemeinsamen Leiter 7 sowie die jeweiligen Teile der Federlaschen 11, die sich zwischen dem umlaufenden Vorsprung 13 des Hülsenteils 9 und den jeweiligen Kontaktstellen 17 der Federlaschen 11 erstrecken, gebildet.In the Figs. 6 to 13 The contact devices shown form the spring tabs 11 each part of a first section of a contact element according to the invention. The two contact points 17 of the outer conductor 2 of the contact device are electrically connected via these, the primary function being the generation of a contact pressure in the upper contact points and the compensation of tolerances with regard to the position and alignment of the contact areas of the components to be connected. Since the lower contact point 17 from the underside of the base part 8 (or from the connection conductor 14 in the contact device according to FIGS Figures 12 and 13 ) is formed, the bottom part 8 (or the connection conductor 14), part of the sleeve part 9 and the annular section 12 are also part of the first section of each of the contact elements. A second section of the individual contact elements, primarily used for electrical connection, is formed by the common conductor 7 and the respective parts of the spring tabs 11, which extend between the circumferential projection 13 of the sleeve part 9 and the respective contact points 17 of the spring tabs 11.

Ein wesentlicher Vorteil der erfindungsgemäßen Kontaktvorrichtung gemäß den Fig. 6 bis 13 ist, dass der Verbindungspfad, der von den zweiten Abschnitten der den Außenleiter 2 ausbildenden Kontaktelemente gebildet wird, im Wesentlichen stets genauso lang ist wie der Signalweg über den Innenleiter 1, wodurch ein entsprechend gleicher Signalweg erreicht werden kann.A major advantage of the contact device according to the invention according to the Figs. 6 to 13 is that the connection path which is formed by the second sections of the contact elements forming the outer conductor 2 is essentially always as long as the signal path via the inner conductor 1, whereby a correspondingly identical signal path can be achieved.

Der Abstand zwischen den zwei Leiterplatten, die mittels eines oder mehrerer der in den Fig. 6 bis 13 dargestellten Kontaktvorrichtungen elektrisch leitend verbunden werden sollen, ist vorzugsweise so groß gewählt, dass sowohl der Innenleiter 1 als auch der Außenleiter 2 des oder der dazwischen angeordneten Kontaktvorrichtung(en) gestaucht ist/sind. Demnach ist zum einen der Kopf 5 des Innenleiters 1 entgegen der Kraft der dadurch weiter vorgespannten Feder 6 ein Stück weit in Richtung des Grunds der Hülse 4 verschoben, während die Federlaschen 11 des Außenleiters 2 in Richtung der Längsachse der Kontaktvorrichtung gestaucht sind, was mit einer Verkleinerung ihres Krümmungsradius bzw. ihrer Krümmungsradien und daher mit einer zunehmenden Vorspannung der Federlaschen 11 verbunden ist. Die vorgesehene Stauchung der Kontaktteile zwischen den Leiterplatten ist dabei vorzugsweise nicht so groß gewählt, dass die Zielleiterplatte die oberen Ränder der Hülse 4 des Innenleiters 1 sowie des Hülsenteils 9 des Außenleiters 2 berührt.The distance between the two circuit boards, which is determined by one or more of the in the Figs. 6 to 13 The contact devices shown are to be connected in an electrically conductive manner, is preferably selected so large that both the inner conductor 1 and the outer conductor 2 of the contact device (s) arranged between them is / are compressed. Accordingly, on the one hand, the head 5 of the inner conductor 1 is shifted a bit in the direction of the base of the sleeve 4 against the force of the spring 6, which is thereby further pretensioned, while the spring tabs 11 of the outer conductor 2 are compressed in the direction of the longitudinal axis of the contact device, which is a A reduction in their radius of curvature or their radii of curvature and therefore associated with an increasing prestress of the spring tabs 11. The intended compression of the contact parts between the circuit boards is preferably not selected so large that the target circuit board touches the upper edges of the sleeve 4 of the inner conductor 1 and the sleeve part 9 of the outer conductor 2 touches.

Insgesamt wird somit ein "Federweg" in beide Richtungen für sowohl den Innenleiter 1 als auch den Außenleiter 2 der Kontaktteile vorgesehen, durch den Abweichungen von dem Abstandssollmaß in beide Richtungen (größer oder kleiner) ausgeglichen werden können. Solche Abweichungen können insbesondere toleranzbedingt sein, wobei neben Positionierungstoleranzen auch Lagetoleranzen, d.h. insbesondere Abweichungen von der vorgesehenen Parallelität der beiden Leiterplatten bzw. der darauf angeordneten, der jeweiligen Kontaktvorrichtung zugeordneten Kontaktbereiche ausgeglichen werden können. Durch die erfindungsgemäße Ausgestaltung des Außenleiters 2 der Kontaktvorrichtungen mit einer Mehrzahl von individuell deformierbaren Kontaktelementen können diese Lagetoleranzen zudem vergleichsweise groß sein. Der punktförmige Kontakt, den der sphärische Kopf 5 des Innenleiters 1 ausbildet, ist ebenfalls unempfindlich hinsichtlich solcher Abweichungen.Overall, a "spring travel" in both directions is thus provided for both the inner conductor 1 and the outer conductor 2 of the contact parts, by means of which deviations from the nominal distance can be compensated for in both directions (larger or smaller). Such deviations can in particular be due to tolerances, whereby in addition to positioning tolerances also position tolerances, i.e. In particular, deviations from the intended parallelism of the two circuit boards or the contact areas arranged on them and assigned to the respective contact device can be compensated for. As a result of the configuration according to the invention of the outer conductor 2 of the contact devices with a plurality of individually deformable contact elements, these positional tolerances can also be comparatively large. The point-like contact that the spherical head 5 of the inner conductor 1 forms is also insensitive to such deviations.

Bei der Deformation der Federlaschen 11 erfolgt ein Abgleiten und somit eine Relativbewegung zwischen dem Hülsenteil 9 des Außenleiters 2 und den Federlaschen 11 an denjenigen Stellen, an denen diese aneinander anliegen. Dabei sind die Anlagestellen bei der Ausführungsform gemäß den Fig. 6 und 7 stets auf dem umlaufenden Vorsprung 13 des Hülsenteils 9 des Außenleiters 7. Dieser kontaktiert, je nach Deformation der Federlaschen 11, somit unterschiedliche Stellen der Federlaschen 11, wobei vorgesehen ist, dass das Anliegen nur innerhalb desjenigen Abschnitts erfolgt, in dem die Federlaschen 11 parallel verlaufen. Bei den Ausführungsformen gemäß den Fig. 8 bis 11 werden die Anlagestellen dagegen stets von den abgerundeten Endabschnitten der Federlaschen 11 ausgebildet, die die Außenseite des Hülsenteils 9 des Außenleiters 2, je nach Deformation der Federlaschen 11, an unterschiedlichen Stellen berühren.When the spring tabs 11 are deformed, there is a sliding off and thus a relative movement between the sleeve part 9 of the outer conductor 2 and the spring tabs 11 at those points where they rest against one another. The contact points in the embodiment according to FIGS Figures 6 and 7 always on the circumferential projection 13 of the sleeve part 9 of the outer conductor 7. Depending on the deformation of the spring tabs 11, this contacts different points of the spring tabs 11, whereby it is provided that the contact occurs only within that section in which the spring tabs 11 run parallel . In the embodiments according to Figs. 8-11 however, the contact points are always formed by the rounded end sections of the spring tabs 11, which touch the outside of the sleeve part 9 of the outer conductor 2, depending on the deformation of the spring tabs 11, at different points.

Bei den Ausführungsformen gemäß den Fig. 8 bis 11 ist noch vorgesehen, dass der umlaufende Vorsprung 13 auf dem Hülsenteil 9 des gemeinsamen Leiters 7 einen Anschlag für die Aufweitung der Federlaschen 11 ausbildet. In Verbindung mit der Kraftkomponente, die die Federvorspannung der Federlaschen 11 in radialer Richtung gegen das Hülsenteil 9 des Außenleiters 2 ausüben, können die Federlaschen 11 dadurch auch im unbelasteten Zustand, d.h. wenn diese nicht zwischen zwei entsprechend beabstandeten Leiterplatten angeordnet sind, vorgespannt gehalten sein.In the embodiments according to Figs. 8-11 it is also provided that the circumferential projection 13 on the sleeve part 9 of the common conductor 7 forms a stop for the widening of the spring tabs 11. In conjunction with the force component that exerts the spring preload of the spring tabs 11 in the radial direction against the sleeve part 9 of the outer conductor 2, the spring tabs 11 can thereby be kept biased even in the unloaded state, ie when they are not arranged between two appropriately spaced printed circuit boards.
