Das leiterplattenseitige Ende des Innenleiterstiftes ist so ausgestaltet, dass er eine gewisse seitliche Auslenkung der kontaktierenden Buchse in einem definierten Bereich zulässt. Mit Vorteil weist der Innenleiter an seinem leiterplattenseitigen Ende einen kugelförmigen Endbereich auf, welcher im montierten Zustand in die Buchse hineinragt und diese entlang einer Innenfläche elektrisch leitend kontaktiert. Je nach Anforderungen können anders geformte Endbereiche verwendet werden. Z.B. kann bei einer von einer Kugelform abweichenden Endfläche eine Rückstellkraft erzeugt werden, indem die federelastisch ausgebildete Verbindungshülse bei einer Auslenkung kontrolliert deformiert wird.The circuit board-side end of the inner conductor pin is designed so that it allows a certain lateral deflection of the contacting socket in a defined area. Advantageously, the inner conductor has a spherical end region at its end on the printed circuit board side, which protrudes into the socket in the mounted state and makes it electrically conductive along an inner surface. Depending on the requirements, differently shaped end areas can be used. For example, can be generated at a deviating from a spherical shape end surface, a restoring force by the resiliently formed connecting sleeve is deformed deformed in a deflection.

Isolator, Innenleiterstift und Buchse können als vormontierte Baugruppe in der Frontplatte z.B. durch Einpressen befestigt werden. Die Frontplatte kann als Aussenleiter des Verbinders dienen. Als Hochfrequenzabschirmung zwischen Frontplatte und Leiterplatte wird mit Vorteil eine leitende EMI-Dichtung (Elektromagnetische Interferenz) eingesetzt. In einer Ausführungsform wird diese Abschirmung überstehend in der Frontplatte eingelassen. Die EMI-Dichtung kontaktiert die Masse der Leiterplatte. In wirkverbundenem Zustand wird die Abschirmung in axialer Richtung zusammengedrückt, abhängig vom Abstand zwischen Front- und Leiterplatte.Insulator, inner conductor pin and socket can be used as a preassembled module in the front panel, e.g. be attached by pressing. The front panel can serve as an outer conductor of the connector. As a high-frequency shield between the front panel and circuit board is advantageously a conductive EMI gasket (electromagnetic interference) is used. In one embodiment, this shield is recessed into the front panel. The EMI gasket contacts the ground of the PCB. In an operatively connected state, the shield is compressed in the axial direction, depending on the distance between the front and circuit board.

Aus dem Stand der Technik bekannte Lösungen basieren in der Regel auf einem Steckverbinderpaar mit einem ersten und einem zweiten Verbinderteil, welche durch ein koaxial aufgebautes Übergansstück miteinander wirkverbindbar sind. Sowohl die Verbinderteile als auch das Übergangsstück weisen einen koaxialen, häufig komplizierten Aufbau auf und sind damit vergleichsweise teuer. Andere aus dem Stand der Technik bekannte Verbinder kontaktieren die Leiterplatte ohne genügende HF-Abschirmung oder weisen einen ungenügenden Toleranzausgleich auf. Ein erfindungsgemässer Verbinder weist diese Nachteile nicht auf und beschränkt sich auf ein Minimum an Bauteilen.Solutions known from the prior art are generally based on a connector pair having a first and a second connector part, which are operatively connected to one another by a coaxially constructed transition piece. Both the connector parts and the transition piece have a coaxial, often complicated structure and are therefore relatively expensive. Contact other connectors known in the art the circuit board without sufficient RF shielding or have an insufficient tolerance compensation. A connector according to the invention does not have these disadvantages and is limited to a minimum of components.

In einer Ausführungsform umfasst der Koaxialverbinder ein erstes koaxiales Verbinderteil mit einem Aussenleiter und einem gegenüber diesem mittels eines Isolators gehaltenen Innenleiter. Der Innenleiter ist in einer Öffnung des Isolators angeordnet und weist ein Endstück auf, welches mit einer elektrisch leitfähig ausgestalteten Verbindungshülse elektrisch leitend wirkverbunden ist. Die Verbindungshülse ist mit dem Isolator über erste Wirkverbindungsmittel mechanisch wirkverbunden. Die mechanische Wirkverbindung ist so ausgestaltet, dass die Verbindungshülse in seitlicher Richtung um einen Winkel α gekippt werden kann. Ein Längenausgleich in axialer Richtung (senkrecht zur gegenüberliegenden Leiterplatte) wird z.B. durch die Wirkverbindung mit einem zweiten, stiftförmigen Verbinderteil wie nachfolgend beschrieben ermöglicht.In one embodiment, the coaxial connector comprises a first coaxial connector part with an outer conductor and an inner conductor held with respect to this by means of an insulator. The inner conductor is arranged in an opening of the insulator and has an end piece which is electrically conductively connected to an electrically conductive configured connecting sleeve. The connection sleeve is mechanically operatively connected to the isolator via first operative connection means. The mechanical operative connection is designed so that the connecting sleeve can be tilted in the lateral direction by an angle α. A length compensation in the axial direction (perpendicular to the opposite printed circuit board) is e.g. by the operative connection with a second, pin-shaped connector part as described below.

Das erste Verbinderteil kann ein kugelförmig ausgebildetes Endstück aufweisen, welches in montiertem Zustand mit einer Innenfläche der Verbindungshülse zusammenwirkt. Das Wirkverbindungsmittel kann aus einer an der Verbindungshülse ausgebildeten Verdickung und einer im Innern der Öffnung des Isolators angeordnete Nut bestehen, in welche die Verdickung im montierten Zustand eingreift. Die Verdickung und die Nut sind mit Vorteil so ausgestaltet, dass die Verbindungshülse in seitlicher Richtung bis zu einem gewissen Kippwinkel, resp. Auslenkwinkel, verkippt werden kann. Gute Resultate werden erzielt, wenn die Verdickung oberhalb des Endstückes angeordnet ist, da dadurch der mögliche Kippwinkel nicht negativ eingeschränkt wird. Bei Bedarf kann die Verbindungshülse Schlitze aufweisen, welche die Randbereiche elastisch machen, so dass die Verbindungshülse eingeschnappt werden kann.The first connector part may have a spherically formed end piece, which cooperates in the assembled state with an inner surface of the connecting sleeve. The operative connection means may consist of a thickening formed on the connecting sleeve and a groove arranged in the interior of the opening of the insulator, in which the thickening engages in the mounted state. The thickening and the groove are advantageously designed so that the connection sleeve in the lateral direction up to a certain tilt angle, respectively. Deflection angle, can be tilted. Good results are achieved if the thickening is arranged above the end piece, since this does not negatively restrict the possible tilt angle. If necessary, the connection sleeve may have slots which make the edge regions elastic, so that the connection sleeve can be snapped.

In einer Ausführungsform weist die Verbindungshülse einen nach innen gerichteten Vorsprung mit einer konisch ausgebildeten Leitfläche auf, die in eine Verbindungsöffnung mündet, welche zur Aufnahme eines stiftförmigen zweiten Verbinderteils geeignet ist. Der Aussenleiter kann eine Kontaktfläche aufweisen, welche zum Kontaktieren einer Leiterbahn auf einer Leiterplatte dienen kann. Erfindungsgemäß ist an einem platinenseitigen Ende des Aussenleiters, welches zum Kontaktieren einer Leiterbahn auf einer Leiterplatte geeignet ist, eine elektrisch leitende Dichtung aus deformierbarem Material befestigt. Der erfindungsgemässe Verbinder bietet eine gute Hochfrequenz-Abschirmung und erlaubt es gleichzeitig, Positionsungenauigkeiten in axialer und radialer Richtung auszugleichen. In einer Ausführungsform des Koaxialverbinders, welcher zur Überbrückung einer Distanz von 9 mm zwischen einer Leiterplatte (PCB) und einer Gerätefrontplatte geeignet ist, kann ein Axialversatz von bis zu 1 mm, sowie ein Radialversatz von bis zu 0.5 mm kompensiert werden. Bei entsprechender Ausgestaltung sind andere Bereiche möglich. Der erfindungsgemässe Verbinder eignet sich besonders für eine kostengünstige "schwimmende" Anbindung von Hochfrequenz-Komponenten auf eine Leiterkarte. Auf der Leiterkarte muss in der Regel lediglich ein einfacher Innenleiterstift angelötet werden. Die Hochfrequenzabschirmung kann optimal gewährleistet werden, auch wenn es geometrische Fluchtabweichungen zwischen den zu kontaktierenden Elementen gibt. In einem Anwendungsgebiet wird ein Filter direkt mit einer Platine eines Duplexers in einer Mobilfunkbasisstation wirkverbunden.In one embodiment, the connection sleeve has an inwardly directed projection with a conically shaped guide surface which opens into a connection opening which is suitable for receiving a pin-shaped second connector part. The outer conductor may have a contact surface, which may serve for contacting a conductor track on a printed circuit board. According to the invention, an electrically conductive seal made of deformable material is attached to a board-side end of the outer conductor, which is suitable for contacting a conductor track on a printed circuit board. The connector according to the invention provides a good high-frequency shielding and at the same time makes it possible to compensate for position inaccuracies in the axial and radial directions. In one embodiment of the coaxial connector, which is suitable for bridging a distance of 9 mm between a printed circuit board (PCB) and a device front panel, an axial offset of up to 1 mm and a radial offset of up to 0.5 mm can be compensated. With appropriate design, other areas are possible. The connector according to the invention is particularly suitable for a cost-effective "floating" connection of high-frequency components on a printed circuit board. On the circuit board usually only a simple inner conductor pin must be soldered. The high-frequency shielding can be optimally ensured, even if there are geometric deviations between the elements to be contacted. In one application, a filter is operatively connected directly to a board of a duplexer in a mobile radio base station.

In den Figuren 1 und 2 ist der Koaxialverbinder 1 aufgeschnitten dargestellt, damit das Innenleben des Koaxialverbinders 1 besser sichtbar wird.In the Figures 1 and 2 the coaxial connector 1 is shown cut away, so that the inner life of the coaxial connector 1 is better visible.

Der Koaxialverbinder 1 besteht aus einem ersten Verbinderteil 2 und einem zweiten Verbinderteil 3. Der erste Verbinderteil 2 wird z.B. an einem Gehäuse befestigt oder ist in dieses integriert. Je nach Anwendungsgebiet kann der erste Verbinderteil 2 auch so ausgestaltet werden, dass er auf einer Leiterplatte befestigt werden kann.The coaxial connector 1 consists of a first connector part 2 and a second connector part 3. The first connector part 2 is attached to, for example, a housing or is in this integrated. Depending on the field of application, the first connector part 2 can also be designed such that it can be fastened on a printed circuit board.

Der erste Verbinderteil 2 weist einen Innenleiter 4, einen Aussenleiter 5, sowie einen Isolator 6 auf. Der Isolator 6 dient zur Halterung und Positionierung des Innenleiters 4 gegenüber dem Aussenleiter 5 (teilweise geschnitten dargestellt). Der Innenleiter 4 wird von oben her (z-Richtung) bis zu einem Anschlag in den Isolator 5 eingepresst. Der Isolator 5 ist in der gezeigten Darstellung von unten her in den Aussenleiter 6 eingepresst. Andere Befestigungsarten und Aufbauten sind bei Bedarf möglich. In der gezeigten Ausführungsform gemäss den Figuren 1-5 ist der Aussenleiter 6 Teil eines Gehäuses 18 einer nur schematisch dargestellten grösseren Vorrichtung. Der Aussenleiter 6 ist vorstehend ausgebildet. Er ragt durch eine Öffnung 22 einer Abschirmung 21 hindurch, welche auf einer Platine 14 angeordnet ist. Wie in Figur 3 gezeigt, kann der Aussenleiter 5 auch als separates Teil ausgebildet sein, das sich z.B. durch Einpressen oder Löten zum Wirkverbinden mit einem Gehäuse und/oder einer Leiterplatte eignet.The first connector part 2 has an inner conductor 4, an outer conductor 5, and an insulator 6. The insulator 6 serves for holding and positioning the inner conductor 4 with respect to the outer conductor 5 (shown partially in section). The inner conductor 4 is pressed from above (z direction) to a stop in the insulator 5. The insulator 5 is pressed in the representation shown from below into the outer conductor 6. Other types of mounting and structures are possible if required. In the embodiment shown according to the Figures 1-5 the outer conductor 6 is part of a housing 18 of a larger device shown only schematically. The outer conductor 6 is formed above. It protrudes through an opening 22 of a shield 21, which is arranged on a circuit board 14. As in FIG. 3 shown, the outer conductor 5 may also be formed as a separate part, which is suitable for example by pressing or soldering for Wirkverbinden with a housing and / or a circuit board.

Am unteren, platinenseitigen Ende des Aussenleiters 5 ist hier eine Dichtung (EMI Dichtung) 7 befestigt. Die Dichtung 7 besteht aus elektrisch leitendem Material und bildet eine elektrisch leitende Wirkverbindung zwischen dem Aussenleiter 6 und Leiterbahnen (nicht näher dargestellt) der Platine 14. Bei Bedarf kann die Dichtung 7 aus deformierbarem Material hergestellt sein, welches bei einer vergleichsweise geringen Kontaktkraft eine gut leitfähige Verbindung bildet. Ein weiterer Vorteil besteht darin, dass die Dichtung eine Abschirmung des Innenlebens gegen äussere Einflüsse ermöglicht. Je nach Anwendungsgebiet kann der Aussenleiter 5 auch direkt mit den Leiterbahnen der Platine 14 in Wirkverbindung treten.At the bottom, board-side end of the outer conductor 5 a seal (EMI seal) 7 is attached here. The seal 7 is made of electrically conductive material and forms an electrically conductive operative connection between the outer conductor 6 and printed conductors (not shown in detail) of the board 14. If necessary, the seal 7 may be made of deformable material, which at a comparatively low contact force is a good conductive Compound forms. Another advantage is that the seal allows a shielding of the inner life against external influences. Depending on the field of application, the outer conductor 5 can also be in direct contact with the printed conductors of the printed circuit board 14.

Der Innenleiter 2 weist ein Endstück 8 mit einer hier kugelförmigen Endfläche 9 auf, welche in montiertem Zustand in eine Verbindungshülse 10 eingreift und mit dieser elektrisch leitend in Kontakt steht. Je nach Anwendungsgebiet kann die Endfläche 9 auch eine von einer Kugelfläche abweichende Ausgestaltung aufweisen, sofern die seitliche Bewegung nicht negativ beeinträchtigt wird.The inner conductor 2 has an end piece 8 with a spherical end surface 9, which in the assembled state engages in a connection sleeve 10 and is electrically conductive therewith in contact. Depending on the field of application, the end surface 9 may also have a different design from a spherical surface, provided that the lateral movement is not adversely affected.

Der Isolator 6 weist eine axial durchgehende Öffnung 11 auf, in welcher die Verbindungshülse 10 angeordnet ist. Die Öffnung 11 weist einen Hinterschnitt 12 (umlaufende Nut) auf, in welchen eine am hinteren Ende der Verbindungshülse 10 angeordnete, radial nach aussen vorstehende Verdickung 13 eingeschnappt ist. Die umlaufende Nut 12 und die Verdickung 13 bilden gemeinsam erste Wirkverbindungsmittel. Der Hinterschnitt 11 ist in der gezeigten Ausführungsform oberhalb eines Zentrums 25 der kugelförmigen Endfläche 9 angeordnet, wodurch eine feste mechanische Kopplung und eine guter maximaler Auslenkwinkel erreicht wird. Gegen das untere Ende hin weitet sich die Öffnung 11 trichterförmig auf, so dass die Verbindungshülse 10 - wie in Figur 5 dargestellt - in seitlicher Richtung um einen Auslenkwinkel α auslenkbar ist. Die Öffnung 11 ist in der gezeigten Ausführungsform so ausgestaltet, dass sie die Verbindungshülse 10 bei maximaler Auslenkung seitlich stützt. Der Flansch 13 und der Hinterschnitt 12 sind so ausgebildet, dass sie dem Verkippen der Verbindungshülse 10 nicht ungewollt entgegenwirken.The insulator 6 has an axially continuous opening 11, in which the connecting sleeve 10 is arranged. The opening 11 has an undercut 12 (circumferential groove), in which a arranged at the rear end of the connecting sleeve 10, radially outwardly projecting thickening 13 is snapped. The circumferential groove 12 and the thickening 13 together form the first operative connection means. The undercut 11 is arranged in the embodiment shown above a center 25 of the spherical end face 9, whereby a solid mechanical coupling and a good maximum deflection angle is achieved. Towards the lower end, the opening 11 widens in a funnel shape, so that the connecting sleeve 10 - as in FIG. 5 shown - in the lateral direction by a deflection angle α is deflectable. The opening 11 is configured in the embodiment shown so that it supports the connecting sleeve 10 at maximum deflection laterally. The flange 13 and the undercut 12 are formed so that they do not unintentionally counteract the tilting of the connecting sleeve 10.

Die Verbindungshülse 10 wirkt in wirkverbundenem Zustand (vgl. Figuren 1, 3 und 5 ) mit einem Kontaktstift 3 (zweites Verbinderteil) zusammen, der auf einer dem Gehäuse 18 gegenüberliegenden Platine 14 z.B. durch Auflöten (Variante gemäss Figur 5 ) oder Durchstecken und Verlöten (Variante gemäss Figuren 1-3 ) befestigt wird. In der gezeigten Ausführungsform weist die Verbindungshülse 10 am unteren Ende einen nach innen gerichteten Vorsprung 15 auf, der eine Kontaktöffnung 16 bildet vor der eine trichterförmige Leitfläche 17 angeordnet ist. Der Kontaktstift 3 greift in wirkverbundenem Zustand in die Kontaktfläche 16 ein und bildet mit dieser eine elektrisch leitende Verbindung. Die Leitfläche 17 hilft dabei die Verbindungshülse 10 gegenüber dem Kontaktstift 3 auch bei einem gewissen seitlichen Versatz in die richtige Position zu bringen. Die Verbindungshülse 10 ist in entlang des Kontaktstiftes 3 verschiebbar angeordnet, so dass ein axialer Längenausgleich (z-Richtung) möglich ist. Der maximal mögliche axiale Längenausgleich wird u. a. durch die Länge des Kontaktstiftes, sowie der Ausgestaltung der Kontakthülse 10 bestimmt.The connecting sleeve 10 acts in an operatively connected state (cf. FIGS. 1, 3 and 5 ) with a contact pin 3 (second connector part) together, on a housing 18 opposite the board 14, for example by soldering (variant FIG. 5 ) or insertion and soldering (variant according to Figures 1-3 ) is attached. In the embodiment shown, the connecting sleeve 10 has at the lower end an inwardly directed projection 15, which forms a contact opening 16 in front of which a funnel-shaped guide surface 17 is arranged. The contact pin 3 engages in operatively connected state in the contact surface 16 and forms with this an electrically conductive connection. The guide surface 17 helps the connecting sleeve 10 relative to the contact pin 3 even at a certain to bring lateral offset into the correct position. The connecting sleeve 10 is slidably disposed along the contact pin 3, so that an axial length compensation (z-direction) is possible. The maximum possible axial length compensation is determined inter alia by the length of the contact pin, as well as the configuration of the contact sleeve 10.

Damit die Verdickung 13 am hinteren Ende der Verbindungshülse 10 in die umlaufende Nut 12 eingeschnappt werden kann, weist die Verbindungshülse 10 erste Schlitze 23 auf, welche dafür sorgen, dass das hintere Ende beim Einschnappen federelastisch deformiert werden kann. Am vorderen Ende weist die Verbindungshülse 10 zweite Schlitze 24 auf, die dafür sorgen, dass das vordere Ende der Verbindungshülse 10 im Bereich der Kontaktöffnung 16 elastisch federnd aufgeweitet werden kann, so dass der Kontaktstift 3 in diese eingeschoben werden kann.Thus, the thickening 13 can be snapped into the circumferential groove 12 at the rear end of the connecting sleeve 10, the connecting sleeve 10 has first slots 23, which ensure that the rear end can be resiliently deformed when snapping. At the front end, the connecting sleeve 10 has second slots 24, which ensure that the front end of the connecting sleeve 10 can be elastically resiliently expanded in the region of the contact opening 16, so that the contact pin 3 can be inserted into this.

Der Innenleiter 4, der Aussenleiter 5, sowie die Verbindungshülse 10 sind bevorzugt als Drehteile (Décolletage-Teile) aus Metall hergestellt.The inner conductor 4, the outer conductor 5, and the connecting sleeve 10 are preferably made of metal as turned parts (Décolletage parts).

Das nicht erfindungsgemäße Beispiel gemäss den Figuren 6 und 7 weist vom Prinzip her denselben Aufbau auf wie die Ausführungsform gemäss den Figuren 1-5. Bezüglich der allgemeinen Beschreibung wird auf die entsprechenden Ausführungen verwiesen. Wie in der Schnittdarstellung gemäss Figur 7 zu erkennen ist, sind in dem Beispiel zwei EMI-Dichtungen 7 vorhanden, welche den Aussenleiter 5 mit der Platine über eine Aussenleiterhülse 26 wirkverbinden. In dem gezeigten Beispiel sind die beiden EMI-Dichtungen 7 und die Aussenleiterhülse 26 mit der Platine 14 verklebt und bleiben beim Lösen des ersten Verbinderteils an dieser haften. Bei Bedarf sind andere Trennungen möglich. Z.B. können die obere Dichtung 7, sowie die Aussenleiterhülse 26 am ersten Verbinderteil 1 haften bleiben. In einer weiteren Ausführungsform können beide Dichtungen 7 und die Aussenleiterhülse 26 beim Lösen des ersten Verbinderteils 2 vom zweiten Verbinderteil 3 am ersten Verbinderteil 2 haften bleiben. Der Isolator 6 wird durch eine hier ringförmige Halterung 27 im Aussenleiter 5 fixiert.The non-inventive example according to the FIGS. 6 and 7 has in principle the same structure as the embodiment according to the Figures 1-5 , With regard to the general description, reference is made to the corresponding statements. As in the sectional view according to FIG. 7 can be seen, in the example, two EMI gaskets 7 are present, which operatively connect the outer conductor 5 to the board via an outer conductor sleeve 26. In the example shown, the two EMI seals 7 and the outer conductor sleeve 26 are glued to the circuit board 14 and stick to the release of the first connector part to this. If necessary, others Separations possible. For example, the upper seal 7, as well as the outer conductor sleeve 26 may adhere to the first connector part 1. In a further embodiment, both seals 7 and the outer conductor sleeve 26 when releasing the first connector part 2 from the second connector part 3 on the first connector part 2 adhere. The insulator 6 is fixed by an here annular holder 27 in the outer conductor 5.

Ein weiterer Unterschied besteht darin, dass der Isolator 6 eine kürzere Ausgestaltung aufweist. Die Verbindungshülse 10 ist in seitlicher Richtung um einen Auslenkwinkel α auslenkbar. Sie wird bei maximaler Auslenkung durch die Seitenwand der trichterförmigen Öffnung 11 seitlich gestützt. Der gezeigte Verbinder 1 ist so ausgestaltet, dass ein seitlicher Versatz (radiale Richtung xy-Ebene) zwischen dem ersten und dem zweiten Verbinderteil 2, 3 von bis zu 0.6 mm und in axialer Richtung (z-Richtung) vom 1mm problemlos kompensiert werden kann.

The connecting sleeve 10 is deflectable in the lateral direction by a deflection angle α. It is supported laterally at maximum deflection by the side wall of the funnel-shaped opening 11. The connector 1 shown is designed so that a lateral offset (radial direction xy plane) between the first and the second connector part 2, 3 of up to 0.6 mm and in the axial direction (z-direction) of 1mm can be easily compensated.
