Description

Die Erfindung betrifft eine HF-Steckverbindung mit einem Steckerkopf und mit einer Buchse, die an ihrem steckerseitigen Ende eine konzentrische Ausnehmung mit einer innenwandigen Ringfläche aufweist.The invention relates to an RF connector with a plug head and with a socket on its plug-side End of a concentric recess with an inner wall Has annular surface.

HF-Steckverbindungen dieser Konstruktion, die als HF-Kontakte zunehmend auch bei Mobilfunktelefonen Verwendung finden, sind vielfach bekannt und bedürfen daher keiner weiteren Erläuterung.RF connectors of this design, called RF contacts increasingly also be used in mobile phones, are often known and therefore require no further explanation.

Bei Steckverbindungen der einleitend angegebenen Gattung wird ein elektrischer Kontakt zwischen Buchse und Stecker typischerweise dadurch erzielt, daß der Steckerkopf in eine eigens dafür vorgesehene Ausnehmung in der Buchse gesteckt wird. Mit derartigen Steckverbindungen läßt sich jedoch der geforderte, sehr niedrige und vor allem auch über die gesamte Lebensdauer des HF-Kontaktes im wesentlichen konstante Kontaktierungswiderstand zwischen Steckerkopf und Buchse nicht erreichen. Mit anderen Worten ist die bisher erzielbare Kontaktierungsgüte nicht immer ausreichend.For connectors of the type initially mentioned is an electrical contact between socket and plug typically achieved in that the plug head in a specially provided recess in the socket plugged becomes. With such connectors, however, can be demanded, very low and above all over the entire Life of the RF contact substantially constant contact resistance not between plug head and socket to reach. In other words, the previously achievable Kontaktierungsgüte not always enough.

Dokument DE-A-4 113473 beschreibt eine Steckverbindung gemäß dem Oberbegriff des Anspruchs 1.Document DE-A-4 113473 describes a plug connection according to the preamble of claim 1.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine HF-Steckverbindung anzugeben, die einen möglichst guten elektrischen Kontakt zwischen Steckerkopf und Buchse gewährleistet. The present invention is therefore based on the object specify an RF connector, the best possible ensures electrical contact between plug head and socket.

Diese Aufgabe wird erfindungsgemäß durch eine HF-Steckverbindung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by an RF connector solved with the features of claim 1.

Demgemäß ist eine HF-Steckverbindung der eingangs genannten Gattung vorgesehen, bei der in der innenwandigen Ringfläche der Buchse mindestens eine ringförmige Ausnehmung vorgesehen ist, in die jeweils ein leitfähiger Federring derart festgeklemmt ist, daß der Steckerkopf unter elektrischer Kontaktgabe des Federrings radial von außen in die konzentrische Ausnehmung der Buchse einsteckbar ist.Accordingly, an RF connector of the aforementioned Species provided, in which in the inner-walled annular surface the sleeve provided at least one annular recess is, clamped in the respective one conductive spring ring in such a way is that the plug head under electrical contact of the spring ring radially from the outside into the concentric recess the socket is inserted.

Die Unteransprüche sind auf bevorzugte Ausgestaltungen und Weiterbildungen der Erfindung gerichtet.The dependent claims are on preferred embodiments and Developments of the invention directed.

In einer in der Buchse eingearbeiteten Ausnehmung ist eine Federring eingeklemmt. Erfindungswesentlich ist hierbei, daß der Federring zumindest teilweise über die innenwandige Ringfläche der Buchse in die für den Steckerkopf vorgesehene Ausnehmung ragt, so daß der Steckerkopf in die Buchse einklipst, wenn er von außen in die Buchse eingeschoben wird. Der erfindungsgemäßen Steckerverbindung liegt die Erkenntnis zugrunde, daß beim Einschieben des Steckerkopfes in die Buchse der Steckerkopf den elastischer ausgebildeten Federring beiseite schiebt, wodurch dieser in die Führung der ringförmige Ausnehmung gedrückt wird. Auf diese Weise kann ein definierter elektrischer Kontakt und damit ein niedriger Kontaktierungswiderstand des Federrings zum Steckerkopf und zur Buchse gewährleistet werden. Insbesondere kann die Forderung eines guten elektrischen Kontaktes auch bei einer langen Lebensdauer des HF-Kontaktes noch gewährleistet werden. In a recess incorporated in the socket is a Pinched spring ring. Essential to the invention here is that the spring ring at least partially over the inner-walled annular surface the socket in the recess provided for the plug head recess protrudes, so that the plug head clasps into the socket, if it is inserted from the outside into the socket. The inventive Plug connection is based on the knowledge that when inserting the plug head into the socket of the plug head the elastic spring ring aside pushes, causing this in the leadership of the annular recess is pressed. In this way, a defined electrical contact and thus a low contact resistance the spring ring ensures the plug head and the socket become. In particular, the requirement of a good electrical contact even with a long life the RF contact still be guaranteed.

Aus Kostengründen ist es ferner vorteilhaft, daß der Federring nicht fest mit der Buchse verbunden ist, sondern wieder aus der Buchse entfernbar ist. Dadurch muß bei einem HF-Kontakt mit einem defekten bzw. durch häufiges Öffnen abgenutzen Federring lediglich dieser Federring und nicht die gesamte Buchse ausgetauscht werden.For cost reasons, it is also advantageous that the spring ring not firmly connected to the jack, but again is removable from the socket. This must be at an RF contact wear with a broken or frequent opening Spring ring only this spring ring and not the entire Replace the socket.

Eine typische HF-Steckverbindung enthält einen Steckerkopf, der eine zylinderförmige Außenleiter-Kontakthülse zur Kontaktierung eines Außenleiters eines Koaxialkabels und einen innerhalb des Außenleiters angeordneten und durch ein Dielektrikum von diesem getrennten Innenleiter aufweist. Besonders vorteilhaft ist es, wenn die Außenleiter-Kontakthülse im Bereich konzentrischen Ausnehmung eine zylindrische Form aufweist. Jedoch wäre auch jede andere Form, wie beispielsweise eine konische, kegelstumpfförmige oder ähnliche Form denkbar.A typical RF connector contains a plug head, the a cylindrical outer conductor contact sleeve for contacting an outer conductor of a coaxial cable and an inside arranged the outer conductor and through a dielectric from this separate inner conductor. Especially It is advantageous if the outer conductor contact sleeve in the area concentric recess has a cylindrical shape. However, any other shape, such as a conical, frustoconical or similar shape conceivable.

Eine deutliche Verbesserung der Kontaktierung kann dadurch erzielt werden, daß der die Buchse und den Stecker kontaktierende Federring einen durchgehenden Schlitz aufweist. Durch diesen Schlitz wird die Elastizität des Federringes und damit die elektrische Kontaktierung signifikant verbessert. Vorzugsweise ist der Schlitz an einer der Ecken des Federringes angeordnet. Bei einem Einschieben des Steckerkopfes in die Buchse kann sich so der Federring, indem sich dessen Schlitz etwas öffnet, optimal an die neue Konstellation anpassen. Auf diese Weise werden zudem zusätzliche Verspannungen des Federringes, die negativen Einfluß auf dessen Lebensdauer haben, weitestgehend vermieden. A significant improvement in the contact can thereby be achieved that the contacting the socket and the plug Spring ring has a continuous slot. By This slot is the elasticity of the spring ring and thus significantly improved the electrical contact. Preferably is the slot at one of the corners of the spring ring arranged. When inserting the plug head in the Socket can become so the spring ring, by itself the slot opens something, optimally adapt to the new constellation. On This way, additional tension of the spring ring, which have a negative influence on its lifetime, largely avoided.

In diesem Zusammenhang ist es besonders vorteilhaft, wenn der Durchmesser der ringförmigen Ausnehmung etwas größer ist als der Querschnitt des Federrings. Durch das Einschieben des Steckerkopfes in die Buchse kann somit der Federring in die ringförmige Ausnehmung gedrückt werden, wobei die ringförmige Ausnehmung als Führung die Bewegungsrichtung des Federringes vorgibt. Durch diese Bewegung des Federringes in die ringförmige Ausnehmung kann der Federring derart verspannt werden, daß ein optimaler elektrischer Kontakt zwischen Buchse und Stecker entsteht.In this context, it is particularly advantageous if the Diameter of the annular recess is slightly larger than the cross section of the spring ring. By inserting the Plug head into the socket can thus the spring ring in the annular recess are pressed, wherein the annular Recess as a guide, the direction of movement of the spring ring pretends. By this movement of the spring ring in the annular Recess of the spring ring can be clamped in such a way that an optimal electrical contact between socket and Plug is created.

In einer bevorzugten Ausgestaltung ist der Federring triangelförmig ausgebildet. Der triangelförmige Federring kontaktiert an seinen Ecken die ringförmige Ausnehmung der Buchse und an seinen Sehnen die zylinderförmige Außenleiter-Kontakthülse des Steckerkopfes. Durch diese je drei Kontaktflächen zur Buchse bzw. zum Steckerkopf wird eine sehr gute Kontaktsicherheit gewährleistet.In a preferred embodiment, the spring ring is triangular educated. The triangular spring ring contacted at its corners, the annular recess of the socket and at its chords the cylindrical outer conductor contact sleeve of the plug head. Through these three contact surfaces to the socket or the plug head is a very good contact reliability guaranteed.

Es wäre selbstverständlich auch von Vorteil, wenn der Federring eine quadratischen, pentagonale, hexagonale, etc. Form aufweist. Insbesondere bei Verwendung von solchen mehreckigen Federringen ließe sich aufgrund der größeren Anzahl von Kontaktflächen im Vergleich zu triangelförmigen Federringen die gesamte Kontaktfläche erhöhen und damit der elektrische Kontakt noch verbessern. Denkbar wären auch an einer Seite geschlitzte Federringe.It would of course also be advantageous if the spring washer a square, pentagonal, hexagonal, etc. shape having. Especially when using such polygonal Circlips could be due to the larger number of contact surfaces compared to triangular spring washers the increase the entire contact surface and thus the electrical contact even better. It would also be possible Slotted spring washers on one side.

Aus herstellungstechnischen Gründen ist es von Nutzen, wenn der Federring aus drahtförmigem Material besteht. In diesem Zusammenhang ist es weiters vorteilhaft, wenn dieser drahtförmige Federring zumindest teilweise aus Federstahl besteht, da Federstahl typischerweise über eine sehr lange Zeitdauer die gewünschte Elastizität behält und darüber hinaus eine sehr gute elektrische Leitfähigkeit aufweist.For manufacturing reasons, it is useful if the spring ring consists of wire-shaped material. In this It is also advantageous if this wire-shaped Spring ring consists at least partially of spring steel, spring steel is typically over a very long period of time maintains the desired elasticity and beyond a has very good electrical conductivity.

Ein weitere Verbesserung der elektrischen Kontaktierung läßt sich durch eine ringförmige Einrastrille, die in die Außenwand der Außenleiter-Kontakthülse des Steckerkopfes eingearbeitet ist, erzielen. Wird der Steckerkopf in die Buchse gesteckt, dann klipst der Federring in diese Einrastrille ein. Eine derartige Einrastrille erweist sich als sehr zweckmäßig, da sich dadurch der Stecker nicht versehentlich, beispielsweise durch Vibrationen oder eine leichte Zugbewegung, wieder aus der Buchse lösen kann und der HF-Kontakt dadurch ungewollt unterbrochen wird. Um den eingeklipsten Federring wieder aus der Einrastrille zu lösen, ist es sodann erforderlich, eine gewisse Zugkraft auf den Steckerkopf entgegen der Einschubrichtung auszuüben.A further improvement of the electrical contact allows through an annular detent groove, which is in the outer wall the outer conductor contact sleeve of the plug head incorporated is, achieve. If the plug head is inserted into the socket, then clip the spring ring into this Einrastrille. Such Einrastrille proves to be very useful, As a result, the plug is not accidentally, for example through vibrations or a slight pulling movement, again can solve the jack and the RF contact unintentionally is interrupted. To the clipped spring ring again from the snap-in groove, it is then necessary a certain tensile force on the plug head against the Exercise insertion direction.

In diesem Zusammenhang ist es besonders vorteilhaft, wenn der Draht des Federringes die Einrastrille maximal in einem Winkel von 120° kontaktiert, da bis zu diesem Winkel die aufzubringende Zugkraft zum Lösen der Steckverbindung nicht zu groß ist.In this context, it is particularly advantageous if the Wire of the spring ring the Einrastrille maximum at an angle contacted by 120 °, since up to this angle to be applied Pulling force to release the connector not to is great.

Eine bestmögliche elektrische Kontaktierung erhält man ferner, wenn der Durchmesser der Einrastrille und der Durchmesser des Drahts des Federrings annähernd gleich groß gewählt sind. In diesem Fall ist die gemeinsame Oberfläche von Einrastrille und Draht am größten, wodurch ein optimaler elektrischer Kontakt erzielt werden kann. A best possible electrical contact is obtained further, if the diameter of the Einrastrille and the diameter the wire of the spring ring chosen approximately equal are. In this case, the common surface of Einrastrille and wire at the greatest, creating an optimal electrical Contact can be achieved.

Schließlich empfiehlt es sich, daß der Durchmesser des Drahts des Federrings und die Höhe der ringförmigen Ausnehmung annähernd gleich groß sind. Auf diese Weise wird gewährleistet, das der Federring in der Führung der ringförmigen Ausnehmung nahezu kein Spiel aufweist und somit ein stabiler HF-Kontakt geschaffen wird.Finally, it is recommended that the diameter of the wire of the spring ring and the height of the annular recess approximately are the same size. This ensures that that of the spring ring in the leadership of the annular recess has almost no play and thus a stable RF contact is created.

Der Steckerkopf 3 besteht hier aus einer Außenleiter-Kontakthülse 4 und einen Steckerkern 5. Der Steckerkern 5 umfaßt einen in Figur 1 nicht gezeigten durch ein Dielektrikum von der Außenleiter-Kontakthülse 4 getrennten Innenleiter. Ferner weist der Steckerkopf 3 eine Einrastrille 6 auf, deren Funktion nachfolgend anhand von Figur 2 noch genau erläutert wird. Damit der Steckerkopf 3 besser in die Buchse 2 eingeführt werden kann, ist eine Einführphase 7 an dem buchsenseitigen Ende des Steckerkopfes 3 vorgesehen.The plug head 3 consists here of an outer conductor contact sleeve 4 and a plug core 5. The plug core 5 includes a not shown in Figure 1 by a dielectric of the Outer conductor contact sleeve 4 separate inner conductor. Further has the plug head 3 a Einrastrille 6, whose function Explained in detail below with reference to FIG 2 becomes. So that the plug head 3 better inserted into the socket 2 can be, is an insertion phase 7 on the socket side End of the plug head 3 is provided.

Die Buchse 2 weist an der zum Steckerkopf 3 entgegengesetzten Seite einen Flansch 8 auf, über den die Buchse 2 beispielsweise mit einem Gehäuse eines HF-Geräts verbunden werden kann. Ferner weist die Buchse 2 einen Buchsenkern 9 auf, in dem ein von der Buchsenhülle 10 durch ein Dielektrikum getrennter Innenleiter vorgesehen ist(in Figur 1 nicht dargestellt). In dem steckerseitigen Ende der Buchse 2 ist eine zum Buchsenkern 9 konzentrische Ausnehmung 11 vorgesehen, in die der Steckerkopf 3 nahezu bündig einsteckbar ist. Durch diese konzentrische Ausnehmung 11 wird eine Innenwandung definiert, die aus einer in Einschubrichtung I des Steckerkopfes 3 befindlichen Stirnfläche 12 und einer seitlich dazu angeordneten Ringfläche 13 besteht.The socket 2 has opposite to the plug head 3 Side a flange 8, over which the socket 2, for example be connected to a housing of an RF device can. Furthermore, the socket 2 a bushing core 9, in one separated from the female shell 10 by a dielectric Inner conductor is provided (not shown in Figure 1). In the plug-side end of the socket 2 is a to the bushing core 9 concentric recess 11 provided in the plug head 3 is almost flush plugged. By this concentric recess 11 is defined an inner wall, from a plug-in direction I of the plug head 3 located end face 12 and one arranged laterally thereto Ring surface 13 is made.

In die Ringfläche 13 ist eine ringförmige Ausnehmung 14 vorgesehen, in die ein Federring 15 eingeschoben ist. Es ist hierbei darauf zu achten, daß die ringförmige Ausnehmung 14 sowie der darin angeordnete Federring 15 und die Einrastrille 6 sich bei eingeschobenem Steckerkopf 3 im wesentlichen in einer Ebene befinden und der Steckerkopf 3 dabei möglichst nicht die Stirnfläche 12 der konzentrische Ausnehmung 14 kontaktiert.In the annular surface 13, an annular recess 14 is provided, in which a spring ring 15 is inserted. It is In this case, make sure that the annular recess 14th and the spring ring 15 disposed therein and the Einrastrille 6 is at inserted plug head 3 substantially in a level and the plug head 3 while possible not the end face 12 of the concentric recess 14 contacted.

Figur 2 zeigt einen Querschnitt der erfindungsgemäßen HF-Steckerverbindung gemäß Figur 1 in der Ebene des Federringes 15. Der Federring 15 in Figur 2 hat die Form einer Triangel, wobei ein Schlitz 16 an einer der Ecken 17 des triangelfömigen Federringes 15 vorgesehen ist. Der so ausgebildete triangelförmige Federring 15 kontaktiert an den Ecken 17 des Federringes 15 über drei Kontaktflächen 18 die Buchse 2 an deren ringförmigen Ausnehmung 14. Ferner kontaktiert der Federring 15 über seine Sehnen 19 drei weitere Kontaktflächen 20 an der Außenwandung der 21 der zylinderförmigen Außenleiter-Kontakthülse 4. Durch diese Kontaktflächen 18, 20 kann eine sehr gute Kontaktsicherheit zwischen Federring 15 und Buchse 2 bzw. Steckerkopf 3 gewährleistet werden.FIG. 2 shows a cross section of the HF plug connection according to the invention according to Figure 1 in the plane of the spring ring 15. The spring ring 15 in Figure 2 has the shape of a triangle, wherein a slot 16 at one of the corners 17 of the triangular Spring ring 15 is provided.

Der Durchmesser d2 der ringförmigen Ausnehmung 14 sollte zumindest minimal kleiner sein als der doppelte Radius r1 des Federringes 15, wobei der Radius r1 des Federringes 15 definiert wird als der Abstand des Mittelpunktes des Federringes 15 zu einem seiner Außenecken 17 bei unbelastetem Zustand des Federringes (vgl. strichlierte Kontur in Fig. 2).The diameter d2 of the annular recess 14 should at least be minimally smaller than twice the radius r1 of the Spring ring 15, wherein the radius r1 of the spring ring 15 defines is considered the distance of the center of the spring ring 15 to one of its outer corners 17 in the unloaded state of the Spring ring (see dashed contour in Fig. 2).

Die Einrastrille 6 dient zum einen der Fixierung des Federringes 15 auf der Außenwandung 21 der Außenleiter-Kontakthülse 4, wodurch die Kontaktflächen 18 dort vergrößert werden und sich ein verbesserter elektrischer Kontakt ergibt. Zum anderen soll die Einrastrille 6 verhindern, daß sich der Steckerkopf 3 versehentlich aus der Buchse 2 löst. Die besten Ergebnisse ergeben sich, wenn der Federring 15 und die Einrastrille 6 denselben Durchmesser d1 aufweisen und der Federring 15 die Einrastrille 6 in einem Umfang von maximal 120° kontaktiert.The Einrastrille 6 serves for a fixation of the spring ring 15 on the outer wall 21 of the outer conductor contact sleeve 4, whereby the contact surfaces 18 are increased there and gives an improved electrical contact. To the another is to prevent the Einrastrille 6, that the plug head 3 accidentally releases from the socket 2. The best Results arise when the spring ring 15 and the Einrastrille 6 have the same diameter d1 and the spring ring 15 the Einrastrille 6 in a maximum of 120 ° contacted.

Typischerweise - jedoch nicht notwendigerweise - weisen zylindrisch ausgebildete Außenleiter-Kontakthülsen 4 an deren buchsenseitigen Außenwandung 21 einen annähernd gleichen Durchmesser d3 wie die innenwandige Ringfläche 13 der Buchse 2 auf.Typically, but not necessarily, they are cylindrical trained outer conductor contact sleeves 4 at the socket-side outer wall 21 is approximately the same Diameter d3 as the inner walled annular surface 13 of the socket 2 on.

Nachfolgend wird die Funktionsweise der erfindungsgemäßen HF-Steckverbindung anhand der Figuren 1 und 2 kurz erläutert:The operation of the RF connector according to the invention will be described below briefly explained with reference to Figures 1 and 2:

Durch eine Bewegung des Steckerkopfes 3 in Einschubrichtung I wird der Federring 15 in die ringförmige Ausnehmung 14 gedrückt. Die ringförmige Ausnehmung 14 dient dabei dem Federring als Führung und gibt die Bewegungsrichtung II des Federringes 15 vor. Durch die Einführphase 7 am Steckerkopf 3 wird gewährleistet, daß der Federring 15 langsam und nicht abrupt in die ringförmige Ausnehmung 14 gedrückt wird. Auf diese Weise läßt sich ein unerwünschtes Verklemmen des Federringes 15 vermeiden.By a movement of the plug head 3 in the insertion direction I. the spring ring 15 is pressed into the annular recess 14. The annular recess 14 serves the spring ring as a guide and indicates the direction of movement II of the spring ring 15 before. Through the insertion phase 7 on the plug head 3 is ensures that the spring ring 15 is slow and not abrupt is pressed into the annular recess 14. To this Way can be an undesirable jamming of the spring ring 15 avoid.

Durch das Eindrücken des Federringes 15 in die ringförmige Ausnehmung 14 wird der Schlitz 16 in bezüglich Bewegungsrichtung III geöffnet. Gleichzeitig mit der Bewegung des Federringes 15 in die ringförmige Ausnehmung 14 rastet der Federring 15 auch in die Einrastrille 6 ein. Durch dieses Einrasten und die entsprechende Verspannung des Federringes 15 legt sich dieser über die Kontaktflächen 18, 20 optimal an die Buchse 2 und den Steckerkopf 3 an, wodurch ein bestmöglicher elektrischer Kontakt gewährleistet ist.By pressing the spring ring 15 in the annular Recess 14, the slot 16 in respect to the direction of movement III opened. Simultaneously with the movement of the spring ring 15 in the annular recess 14 engages the spring ring 15 also in the Einrastrille 6 a. By this snap and the corresponding tension of the spring ring 15th settles this on the contact surfaces 18, 20 optimally the socket 2 and the plug head 3, whereby a best possible electrical contact is ensured.
