Definitions
- 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.
- electrical connections between two circuit boards are also implemented using spring contact pins in a single-conductor and / or multiple-conductor structure.
- 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.
- spring tabs as contact elements or as part of contact elements are 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.
- a contact device with a plurality of contact elements 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- a contact device is characterized in that it comprises a plurality of contact elements.
- 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.
- a shield for the inner conductor can be formed by a (preferably circular) annular arrangement of the first sections of the contact elements.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the 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)
- 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.
- 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 °.
- 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.
- 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.
- a second section of the individual contact elements 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

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.

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.

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
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.

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
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

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
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

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
