Description

Die Erfindung betrifft eine Antennenbuchse für Geräte der Unterhaltungselektronik, die eine mit einem Kabel-Außenleiter zu verbindende Außenhülse, eine mit einem koaxial angeordneten Kabel-Innenleiter zu verbindende Innenkontaktbuchse und in Axialrichtung angeordnete und über den Innenumfang der Außenhülse verteilte Federstege aufweist.The invention relates to an antenna socket for consumer electronics devices, which has an outer sleeve to be connected to a cable outer conductor, an inner contact socket to be connected to a coaxially arranged cable inner conductor, and spring bars arranged in the axial direction and distributed over the inner circumference of the outer sleeve.

Bei handelsüblichen Antennenbuchsen sind die Federstege an ihren beiden Enden mit je einem in Umfangsrichtung verlaufenden Streifen aus demselben Material verbunden. Diese Streifen liegen an der Innenwand der Außenhülse an. Die Federstege sind in ihren mittleren Bereich durchgebogen, so daß sie nach innen gewölbte Kontaktflächen bilden, die an dem Stecker der Antennenkoaxialleitung federnd anliegen, wenn der Stecker in die Antennenbuchse eingeschoben ist.In commercially available antenna sockets, the spring bars are connected at their two ends to a strip of the same material running in the circumferential direction. These strips lie on the inner wall of the outer sleeve. The spring bars are bent in their central region, so that they form inwardly curved contact surfaces which resiliently rest on the plug of the antenna coaxial line when the plug is inserted into the antenna socket.

Eine derart ausgebildete Antennenbuchse ergibt einen guten Halt für den Antennenstecker und erfüllt die strengsten Anforderungen, die von den Fernmeldeverwaltungen an die elektromagnetische Abschirmung eines Antennenanschlusses gestellt werden, wenn der Außendurchmesser des Steckers genau eingehalten wird. Wird aber in die Antennenbuchse ein Antennenstecker mit etwas geringerem Durchmesser, wie er in einigen Ländern verwendet wird, eingesteckt, so kann die geforderte Abschirmung nicht immer erreicht werden. Für den Anschluß eines Koaxialsteckers an Koaxialkabel mit unterschiedlichen Durchmessern des Außenleiters ist es aus der deutschen Gebrauchsmusterschrift DE-U-8334468 bekannt, in einer elektrisch leitenden Einschubhülse für das Kabelende des Koaxialkabels einen Lamellenkäfig mit axialem Bewegungsspielraum seiner Länge zu lagern, der sich durch Verformung seiner Lamellen an den Durchmesser des Außenleiters des in dem Koaxialstecker zu befestigenden Koaxialkabels anpaßt.An antenna socket designed in this way provides a good hold for the antenna connector and fulfills the strictest requirements placed on the electromagnetic shielding of an antenna connection by the telecommunications administrations if the outside diameter of the connector is exactly adhered to. However, if an antenna connector with a somewhat smaller diameter, as used in some countries, is inserted into the antenna socket, the required shielding cannot always be achieved. For the connection of a coaxial connector to coaxial cable with different diameters of the outer conductor, it is known from German utility model DE-U-8334468 to store a lamella cage with an axial range of motion of its length in an electrically conductive insertion sleeve for the cable end of the coaxial cable, which is deformed by its deformation Fins adapts to the diameter of the outer conductor of the coaxial cable to be fastened in the coaxial connector.

Der Erfindung liegt die Aufgabe zugrunde, eine Antennenbuchse für koaxiale Antennenkabel zu schaffen, die auch bei Verwendung von Antennensteckern mit voneinander abweichenden Außendurchmessern die strengsten Anforderungen an die Abschirmung erfüllt.The invention has for its object to provide an antenna socket for coaxial antenna cables that meets the strictest requirements for shielding even when using antenna plugs with differing outer diameters.

Diese Aufgabe wird erfindungsgemäß durch eine eine Antennenbuchse der eingangsgenannten Art gelöst, bei der ein Teil der Federstege an beiden Enden und der Rest der Federstege an nur einem Ende befestigt sind.This object is achieved according to the invention by an antenna socket of the type mentioned at the beginning, in which a part of the spring bars are attached at both ends and the rest of the spring bars at only one end.

Besonders gute Eigenschaften zeigt eine Antennenbuchse, bei der die beidseitig befestigten Federstege nach innen gekrümmt sind. Zweckmäßigerweise sind die einseitig befestigten Federstege so nach innen umgelenkt, daß sie näher an die Antennenbuchsenachse heranreichen, als die beidseitig befestigten Stege. Eine besonders hohe Abschirmung ergibt eine Antennenbuchse, bei der die einseitig befestigten Federstege etwa in ihrer Mitte nach außen umgeknickt sind. Die Abschirmung ist besonders dann gut, wenn die einseitig befestigten Federstege etwa in ihrer Mitte so nach außen umgelenkt sind, daß mit ihrem freien Ende an die Außenhülsen heranreichen.An antenna socket, in which the spring bars fastened on both sides are curved inwards, shows particularly good properties. The spring webs fastened on one side are expediently deflected inwards such that they come closer to the antenna socket axis than the webs fastened on both sides. A particularly high shielding results in an antenna socket in which the spring bars fastened on one side are bent outwards approximately in their middle. The shield is special then good if the spring bars fastened on one side are deflected outwards approximately in their middle so that their free ends reach the outer sleeves.

Andere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den weiteren Unteransprüchen.Other advantageous developments of the invention result from the further subclaims.

Eine erfindungsgemäße Antennenbuchse 1 weist eine metallische Außenhülse 2 auf, in die der Stecker eines -in der Zeichnung nicht dargestellten - koaxialen Antennenkabels eingesteckt wird (Fig.1). Auf ihrer Innenachse weist sie eine längsgeschlitzte metallische Innenbuchse 3 auf, die der Aufnahme des mit dem Innenleiter des Antennenkabels verbunden Steckerstiftes dient. Die Antennenbuchse 1 wird mittels eines Bajonettverschlußes 5 in dem Gehäuse des Gerätes, z.B. eines Fernsehempfängers, befestigt. Eine Lasche oder Lötfahne 6 dient zum Anschluß des Innenleiters in dem Gerät.An antenna socket 1 according to the invention has a metallic outer sleeve 2, into which the plug of a coaxial antenna cable (not shown in the drawing) is inserted (FIG. 1). On its inner axis, it has a longitudinally slotted metallic inner bush 3, which is used to receive the Inner conductor of the antenna cable connected connector pin is used. The antenna socket 1 is fastened in the housing of the device, for example a television receiver, by means of a bayonet catch 5. A tab or solder lug 6 is used to connect the inner conductor in the device.

In der Nähe des offenen Endes 8 der Antennenbuchse 1 sind über die Innenwand der Außenhülse 2 verteilt eine Vielzahl von Federstegen 9 und 10 angeordnet, und zwar in etwa parallel zu der Achse der Außenhülse 2. Dabei sind die Federstege 9 an ihren beiden Enden - in der Zeichnung links und rechts liegend - befestigt, während die Federstege 10 nur an ihrem einen Ende - in der Zeichnung links liegend - befestigt sind. Die Befestigung erfolgt über einen äußeren Ringsteg 11 und einen inneren Ringsteg 12, die zusammen mit den Federstegen 9 und 10 eine Art elastischen Käfigs bilden.In the vicinity of the open end 8 of the antenna socket 1, a large number of spring bars 9 and 10 are distributed over the inner wall of the outer sleeve 2, approximately parallel to the axis of the outer sleeve 2. The spring bars 9 are at their two ends - in the drawing lying on the left and right - fastened, while the spring bars 10 are only attached at one end - lying on the left in the drawing. The attachment takes place via an outer ring web 11 and an inner ring web 12, which together with the spring webs 9 and 10 form a kind of elastic cage.

Im Innern der Außenhülse 2 ist ein Kunststoffkörper 14 angeordnet, der die axiale Lage der Innenhülse 3 fixiert und als Anschlag für den inneren Ringsteg 12 dient. Die Außenhülse 2 ist in dem Bereich des Endes 8 mit mehreren über ihren Umfang verteilten Sicken 15 versehen, die als Anschlag für den äußeren Ringsteg 11 dienen. Die Ringstege 11 und 12 und damit die Federstege 9 und 10 werden durch den Kunststoffkörper 14 und die Sicken 15 in ihrer Lage in der Antennenbuchse 1 fixiert. Weitere Einzelheiten der Federstege 9, 10 werden anhand der Figuren 2 bis 6 erläutert.A plastic body 14 is arranged in the interior of the outer sleeve 2, which fixes the axial position of the inner sleeve 3 and serves as a stop for the inner ring web 12. The outer sleeve 2 is provided in the region of the end 8 with a plurality of beads 15 distributed over its circumference, which serve as a stop for the outer ring web 11. The ring webs 11 and 12 and thus the spring webs 9 and 10 are fixed in their position in the antenna socket 1 by the plastic body 14 and the beads 15. Further details of the spring bars 9, 10 are explained with reference to FIGS. 2 to 6.

Der elastische Käfig oder Federkäfig 16, der wie erwähnt durch die Federstege 9 und 10 sowie die Ringstege 11 und 12 gebildet wird, ist in Fig. 2 in einer ebenen Abwicklung dargestellt. Er kann in einem Arbeitsgang hergestellt werden, indem U-förmige Abschnitte 18 aus einem Weißblechstreifen oder aus rostfreiem Bandstahl ausgestanzt werden. Die Federstege 9 bleiben sowohl mit dem Ringsteg 11 als auch mit dem Ringsteg 12 verbunden, während die Federstege 10 durch einen Spalt 19 von dem Ringsteg 12 getrennt sind, so daß sie nur mit dem Ringsteg 11 verbunden bleiben. Der Federkäfig 16 wird außerdem so verformt, daß die Federstege 9 eine etwa kreisbogenförmige Krümmung nach der einen Seite erhalten, während die Federstege 11 mit ihrem freien Ende nach der gleichen Seite gebogen werden, wie aus den Figuren 3 und 4 ersichtlich ist.The elastic cage or spring cage 16, which, as mentioned, is formed by the spring bars 9 and 10 and the ring bars 11 and 12, is shown in a flat development in FIG. 2. It can be produced in one operation by punching out U-shaped sections 18 from a tinplate strip or from stainless steel strip. The spring bars 9 remain connected to both the ring bar 11 and the ring bar 12, while the spring bars 10 are separated from the ring bar 12 by a gap 19, so that they remain connected only to the ring bar 11. The spring cage 16 is also deformed in such a way that the spring bars 9 are given an approximately arcuate curvature on one side, while the spring bars 11 are bent with their free end on the same side, as can be seen from FIGS. 3 and 4.

Die Fig. 3 entspricht einer Schnittansicht entsprechend der Linie AB in Fig. 2. Der Federsteg 9 ist an seinem einen Ende mit den äußeren Ringsteg 11 und an seinem anderen Ende mit dem inneren Ringsteg 12 fest verbunden. Dazwischen weist er einen kreisförmig gekrümmten Bereich 20 auf, der in montiertem Zustand in das Innere der Außenhülse 2 hineinragt.3 corresponds to a sectional view along the line AB in FIG. 2. The spring bar 9 is fixedly connected at one end to the outer ring bar 11 and at its other end to the inner ring bar 12. In between, it has a circularly curved region 20 which, when assembled, projects into the interior of the outer sleeve 2.

Die Fig. 4 stellt eine Schnittansicht entsprechend der Linie CD der Fig. 2 dar. Der Federsteg 9 weist die vorstehend erläuterte Gestalt auf, während der Federsteg 10 nur mit seinem einen Ende mit dem äußeren Ringsteg 11 verbunden ist. Anschließend ist er in die gleiche Richtung umgebogen, und zwar so, daß er - in montiertem Zustand - weiter in das Innere der Antennenbuchse 1 hineinragt als der gekrümmte Bereich 20 des Federstegs 9 (vergleiche auch Fig.1).FIG. 4 shows a sectional view along the line CD of FIG. 2. The spring bar 9 has the shape explained above, while the spring bar 10 is only connected at one end to the outer ring bar 11. Then it is bent in the same direction, in such a way that - in the assembled state - it projects further into the interior of the antenna socket 1 than the curved region 20 of the spring bar 9 (see also FIG. 1).

Der Federkäfig 16 wird in einem letzten Arbeitsvorgang noch gerollt und erhält seine aus der - in etwa maßstäblichen - Fig. 5 ersichtliche Gestalt einer offenen Hülse. Der Federkäfig 16 wird dann zusammengedrückt und in die Außenhülse 2 der Antennenbuchse 1 eingesetzt. Er bildet dann in etwa eine geschlossene Hülse, die aufgrund seiner Elastizität an der Außenhülse 2 federnd anliegt. In axialer Richtung wird der Federkäfig 16, wie bereits erwähnt, durch den Kunststoffkörper 14 und die Sicken 15 fixiert.The spring cage 16 is still rolled in a last operation and receives its shape of an open sleeve, which can be seen from the - approximately to scale - FIG. 5. The spring cage 16 is then compressed and inserted into the outer sleeve 2 of the antenna socket 1. It then forms approximately a closed sleeve which rests against the outer sleeve 2 due to its elasticity. As already mentioned, the spring cage 16 is fixed in the axial direction by the plastic body 14 and the beads 15.

Eine gute Abschirmung auch bei Antennensteckern kleineren Durchmessers wird insbesondere dann erreicht, wenn - wie in der linken Hälfte von Fig. 2 dargestellt - nur einseitig, d.h. an ihrem einen Ende, befestigte Federstege 22 verwendet werden, die erheblich kürzer sind als die dazwischenliegenden beidseitig befestigten Federstege 9. Sie können etwa halb so lang sein wie die Federstege 9. Hergestellt werden sie, indem großflächigere Abschnitte 23 aus dem Bandmaterial des Federkäfigs 16 ausgestanzt werden.Good shielding is also achieved with antenna connectors of smaller diameter if - as shown in the left half of Fig. 2 - only on one side, i.e. fixed spring bars 22 are used at one end, which are considerably shorter than the intermediate spring bars 9 which are fastened on both sides. They can be approximately half as long as the spring bars 9. They are produced by punching larger-area sections 23 out of the band material of the spring cage 16 will.

Für Anwendungsfälle, in denen eine besonders hohe Abschirmung gefordert ist, empfiehlt sich eine andere Ausführung der Antennenbuchse, bei der die einseitig befestigten Federstege 21 (vgl. Fig. 6) von dem äußeren Ringsteg 11 an nach innen, d.h. in Richtung auf die Achse der Antennenbuchse zu, umgelenkt oder umgebogen sind, dann aber etwa in ihrer Mitte nach außen umgeknickt sind. Mit ihrem freien Ende 25 reichen sie bis an die Außenhülse 2 heran, dabei können sie auch mit einem gewissen elastischen Druck an der Außenhülse 2 anliegen.For applications in which particularly high shielding is required, a different embodiment of the antenna socket is recommended, in which the spring bars 21 (see FIG. 6) fastened on one side from the outer ring bar 11 to the inside, ie in the direction of the axis of the Antenna socket to, deflected or bent, but then are bent outwards about in the middle. With their free end 25 they reach up to the outer sleeve 2, and they can also bear on the outer sleeve 2 with a certain elastic pressure.

Wird der Stecker einer Antennenkoaxialleitung in eine so geformte Buchse eingeschoben, so führt das freie Ende 25 des Federstegs 21 eine reibende oder "schabende" Bewegung entlang der Antennenhülse 2 durch. Beim Herausziehen des Steckers bewegt sich das freie Ende 25 wieder in entgegengesetzter Richtung. Diese beiden Bewegungen entlang der Außenhülse sind in der Zeichnung durch einen Doppelpfeil 23 angedeutet. Bei eingeführtem Stecker ergibt sich also zwischen dem freien Ende 25 und der Antennenhülse ein guter elektrischer Kontakt.If the plug of an antenna coaxial line is inserted into a socket shaped in this way, the free end 25 of the spring bar 21 carries out a rubbing or "scraping" movement along the antenna sleeve 2. When the plug is pulled out, the free end 25 moves again in the opposite direction. These two movements along the outer sleeve are indicated in the drawing by a double arrow 23. With the plug inserted, there is good electrical contact between the free end 25 and the antenna sleeve.

Wird in die Antennenbuchse 1 ein Koaxialstecker mit einem Außendurchmesser von 9,5 mm eingesteckt, so ergeben bereits die Federstege 9 aufgrund ihrer Elastizität eine gute Halterung der Steckerhülse und eine den Vorschriften entsprechende elektromagnetische Abschirmung. Wird aber in eine Antennenbuchse, die nur mit beidseitig befestigten Federstegen 9 versehen ist, ein ebenfalls, insbesondere im Ausland, üblicher Antennenstecker mit einem Außendurchmesser von 9 mm eingesteckt, so wird er nicht ganz einwandfrei in seiner Lage gehalten. Insbesondere kann dann die durch die strengsten Vorschriften geforderte Abschirmung nicht gewährleistet werden. Die nur an ihrem einen Ende befestigten Federstege 10 und 21 ergeben einen größeren Federweg als die beidseitig befestigten Federstege 9. Sie geben auch Antennensteckern mit kleinerem Außendurchmesser einen sicheren Halt. Darüber hinaus hat sich gezeigt, daß der für netzverbundene Geräte geforderte Grenzwert des Schirmungsmaßes von 40 dB einwandfrei eingehalten wird, wobei die Messungen noch einen beachtlichen Sicherheitsabstand zu diesem Grenzwert ergeben haben.If a coaxial plug with an outer diameter of 9.5 mm is inserted into the antenna socket 1, the spring bars 9 already result in a good retention of the plug sleeve and an electromagnetic shield corresponding to the regulations due to their elasticity. However, if an antenna connector with an outer diameter of 9 mm, which is also common, especially abroad, is inserted into an antenna socket, which is only provided with spring bars 9 fastened on both sides, it is not held in its position quite correctly. In particular, the shielding required by the strictest regulations cannot be guaranteed. The spring bars 10 and 21 which are only attached at one end result in a greater spring travel than the spring bars 9 which are attached on both sides. They also provide a secure hold for antenna plugs with a smaller outside diameter. In addition, it has been shown that the limit value of 40 dB required for network-connected devices of the shielding dimension is properly maintained, whereby the measurements have shown a considerable safety margin to this limit value.
