Description

Die Erfindung bezieht sich auf eine Steckverbinderhälfte, wie Dose oder Stecker, vorzugsweise für Audio-Miniatur-Steckverbinder gemäß dem Oberbegriff von Anspruch 1.The invention relates to a connector half, such as socket or plug, preferably for audio miniature connectors according to the preamble of claim 1.

Audio-Miniatur-Stecker oder -Dosen sind aus der Praxis bereits seit längerem bekannt. Es gibt sie als sogenannte Stift-Buchsen-Steckverbinder oder als Druckkontakt-Steckverbinder. Zum Anschluß der Kabel sind auf der Rückseite des Steckverbinders häufig Lötstifte oder -trichter oder auch sog. Crimp-Anschlüsse vorgesehen. Bei der zunehmenden Miniaturisierung einerseits und der Zunahme der Poldichte andererseits wird es immer schwieriger, die Drahtenden eines Kabels anzulöten oder festzucrimpen. Insbesondere die mittleren Kontakte sind nur schwer zugänglich. Dieses Problem wird dann noch verstärkt, wenn zwischen den Drahtenden der Kabel und den Anschlüssen des Steckverbinders noch irgendwelche Filterelemente vorgesehen werden sollen.Audio miniature plugs or sockets have long been known in practice. They are available as so-called pin-socket connectors or as pressure contact connectors. To connect the cables, solder pins or funnels or so-called crimp connections are often provided on the back of the connector. With increasing miniaturization on the one hand and increasing pole density on the other hand, it is becoming increasingly difficult to solder or crimp the wire ends of a cable. The middle contacts in particular are difficult to access. This problem is exacerbated if any filter elements are to be provided between the wire ends of the cables and the connections of the connector.

Ein gattungsgemäßer Steckverbinder ist aus der FR-A-2557381 bekannt, bei dem in ein Kontaktelement, das eine Anschlußröhrchenseite aufweist, ein Stiftkontakt eingesteckt ist. Der Stift führt durch Bohrungen ein einem Gehäuse gehaltenen kapazitiven Block und einem parallel dazu angeordneten weiteren kapazitiven Block. Zwischen den beiden kapazitiven Blöcken ist ein den Stift umgebende Einrichtung und eine zwischen den beiden Blöcken angeordnete Einrichtung angeordnet. Die Einrichtungen sollen an den Stiften Induktanz hervorrufen, was es erlaubt, π-Filter auszubilden.A generic connector is known from FR-A-2557381, in which a pin contact is inserted into a contact element which has a connecting tube side. The pin leads through bores a capacitive block held in a housing and a further capacitive block arranged parallel to it. Between the two capacitive blocks is a device surrounding the pin and one between the device arranged in both blocks. The devices are said to induce inductance on the pins, which makes it possible to form π filters.

Es ist daher Aufgabe der vorliegenden Erfindung, Steckverbinderhälften der eingangs genannten Art so zu verbessern.It is therefore an object of the present invention to improve connector halves of the type mentioned in the introduction.

Diese Aufgabe wird erfindungsgemäß durch einen Steckverbinder gemäß Anspruch 1 gelöst.This object is achieved by a connector according to claim 1.

Die Audio-Miniatur-Steckverbinder werden als sogenannte Filterstecker konfektioniert, um bei der Übertragung bestimmte Signale herauszufiltern. Solche Filterstecker weisen häufig Filterelemente auf, die als einzelne, zumindest einendig mit Anschlußstiften versehene Filterröhrchen ausgebildet sind und deren Mantelflächen durch eine gemeinsame Massenscheibe mit dem Gehäuse der Steckverbinderhälfte verbunden sind. Gerade bei solchen Steckverbinderhälften ist es günstig, wenn die Anschlußröhrchen der Kabelanschlußseite an ihrer Innenwand über den Umfang verteilt mehrere radial nach innen gerichtete Federzungen aufweisen und wenn die Filterröhrchen mit ihren Anschlußstiften einzeln auswechselbar in die Anschlußröhrchen der Kabelanschlußseite der Steckverbinderhälfte eingesetzt sind. Dadurch, daß die Filterröhrchen in den Anschlußröhrchen kraftschlüssig gehalten sind, ist ein Austausch der Filterröhrchen und damit eine andere Befilterung des Steckverbinders möglich.The audio miniature connectors are assembled as so-called filter connectors to filter out certain signals during transmission. Such filter plugs often have filter elements which are designed as individual filter tubes which are provided at least at one end with connecting pins and whose lateral surfaces are connected to the housing of the connector half by a common ground disk. Especially with such connector halves, it is advantageous if the connecting tubes of the cable connection side have a plurality of radially inwardly directed spring tongues distributed over the circumference on their inner wall and if the filter tubes with their connecting pins are individually replaceable in the connecting tubes of the cable connection side of the connector half. The fact that the filter tubes are held in a force-fitting manner in the connecting tubes makes it possible to exchange the filter tubes and thus to filter the connector differently.

Beim Anlöten der Filterröhrchen ist eine solche Austauschmöglichkeit nicht oder nur mit wirtschaftlich nicht mehr vertretbarem Aufwand möglich.When the filter tubes are soldered on, such an exchange option is not possible or is only possible with economically no longer justifiable effort.

Gemäß einer bevorzugten Ausführungsform erstrecken sich die Federzungen entlang der Achse eines Anschlußröhrchens und laufen vom freien Enden des Anschlußröhrchens aus aufeinander zu. Dadurch wird beim Einstecken der Draht- oder Litzenenden von den Federzungen relativ wenig Widerstand entgegengesetzt.According to a preferred embodiment, the spring tongues extend along the axis of a connecting tube and run towards one another from the free ends of the connecting tube. As a result, relatively little resistance is opposed by the spring tongues when the wire or strand ends are inserted.

Günstig ist es in diesem Zusammenhang, wenn die Federzungen an einer Stelle frei enden, an der sie am dichtesten zueinander benachbart sind. Hierdurch ergibt sich ein Widerhakeneffekt, der das Herausziehen der Draht- oder Litzenenden aus den Anschlußröhrchen erschwert, nicht jedoch verhindert. Verhindert werden soll das Herausziehen auch nicht, da erwünscht ist, daß auf einfache Weise auch Anschlüsse vertauscht werden, ohne daß Lötwerkzeug benötigt wird.In this context, it is advantageous if the spring tongues end freely at a point at which they are closest to one another. This results in a barb effect, which makes it difficult, but not prevents, to pull the wire or strand ends out of the connecting tubes. The pulling out should not be prevented either, since it is desired that connections are exchanged in a simple manner without the need for soldering tools.

Eine besonders sichere Verankerung der freien Draht- oder Litzenenden läßt sich erreichen, wenn je Anschlußröhrchen vier Federzungen vorgesehen sind.A particularly secure anchoring of the free wire or strand ends can be achieved if four spring tongues are provided for each connecting tube.

Um einen guten Massekontakt zwischen dem Mantel der Filterröhrchen und dem Gehäuse der Steckverbinderhälfte zu erreichen, kann in bevorzugter Weise vorgesehen sein, daß die Massenscheibe auf einer radial nach innen gerichteten Schulter des Gehäuses aufliegt und durch einen Anpreßring gegen die Schulter gedrückt wird. Der Anpreßring kann durch Verbördeln des kabelanschlußseitigen freien Gehäuserandes gehalten sein.In order to achieve good ground contact between the jacket of the filter tubes and the housing of the connector half, it can be provided in a preferred manner that the ground disc rests on a radially inward shoulder of the housing and is pressed against the shoulder by a pressure ring. The pressure ring can be held by crimping the free edge of the housing on the cable connection side.

Ferner ist es günstig, wenn der Anpreßring eine radial innen liegende Führungsplatte übergreift, in welcher Durchgangsbohrungen für die Filterröhrchen vorgesehen sind, und wenn an der Führungsplatte ein deren Stirnseite abdeckender Deckel lösbar befestigt ist, der konzentrisch zu den Durchgangsbohrungen der Führungsplatte Öffnungen aufweist, deren Durchmesser geringer ist als der der Filterröhrchen. Auf diese Weise werden die Filterröhrchen in axialer Richtung letztlich nur durch den Deckel formschlüssig gehalten, während die Anschlußröhrchen und auch die Massescheibe die Filterröhrchen lediglich kraftschlüssig halten. Es ist daher möglich, nach Abnehmen des Deckels beliebig viele Filterröhrchen zur Rückseite der Steckverbinderhälfte herauszuziehen und durch andere Filterröhrchen oder auch durch einfache Stifte zu ersetzen. Anschließend wird der Deckel wieder aufgesetzt.It is also expedient if the pressure ring engages over a radially inner guide plate, in which through holes are provided for the filter tubes and if a cover which covers the end face of the guide plate is releasably attached and has openings concentric with the through bores of the guide plate, the diameter of which is smaller than that of the filter tubes. In this way, the filter tubes are ultimately held in a positive manner in the axial direction only by the cover, while the connecting tubes and also the ground disk only hold the filter tubes non-positively. It is therefore possible to remove any number of filter tubes from the back of the connector half after removing the cover and to replace them with other filter tubes or with simple pins. Then the lid is put back on.

Eine baulich besonders einfache Befestigungsmöglichkeit für den Deckel ergibt sich, wenn der Deckel durch einen am Rand desselben vorgesehenen und mit einer Hinterschneidung des Randes der Führungsplatte zusammenwirkenden Clipverschluß gehalten ist.A structurally particularly simple fastening option for the cover is obtained if the cover is held by a clip closure provided on the edge of the cover and cooperating with an undercut of the edge of the guide plate.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Es zeigt:

Fig. 1
ein Ausführungsbeispiel einer erfindungsgemäßen Steckverbinderhälfte in einer teilweise geschnittenen Seitenansicht.
An exemplary embodiment of the invention is explained in more detail below with reference to a drawing. It shows:
Fig. 1
an embodiment of a connector half according to the invention in a partially sectioned side view.

Fig. 1 zeigt eine erfindungsgemäße Steckverbinderhälfte am Beispiel einer Dose eines Audio-Miniatur-Druckkontakt-Steckverbinders.Fig. 1 shows a connector half according to the invention using the example of a socket of an audio miniature pressure contact connector.

Es handelt sich hierbei um eine im wesentlichen rotationssymmetrisch aufgebaute Dose, die auf ihrer entsprechend der Darstellung in Fig. 1 rechten Seite ihre Steckseite 1 aufweist, über die der Kontakt zu einem hier nicht dargestellten Stecker zustandekommt. Auf der gegenüberliegenden Seite (links) befindet sich die Kabelanschlußseite 2 der Steckverbinderhälfte. An dieser Seite weist die Steckverbinderhälfte entsprechend der Anzahl ihrer Pole zylinderrohrförmige Anschlußröhrchen 3 auf. An ihrer Innenwand weisen die zylinderförmigen Anschlußröhrchen 3, über ihren Umfang verteilt vier radial nach innen gerichtete Federzungen auf. Die Federzungen 4 weichen beim Einstecken eines Draht- oder Litzenendes radial nach außen aus, um das Draht- oder Litzenende kraftschlüssig festzuhalten. Die Federzungen 4 sind dabei so angeordnet, daß sie zunächst vom freien Ende der Anschlußröhrchen 3, aus parallel zu deren Achse verlaufen und mit Abstand vom freien Ende aufeinander zulaufen. Dabei enden die Federzungen 4 an einer Stelle, an der sie am dichtesten zueinander benachbart sind. Hieraus ergibt sich ein Widerhakeneffekt, der das Herausziehen eines eingesteckten Anschlußstiftes erschwert. Nachzutragen bleibt noch, daß die Anschlußröhrchen 3, in einem Isolierkörper eingelassen sind, der vom Gehäuse 8 der Dose umgeben ist. Bei der in Fig. 1 dargestellten Dose handelt es sich um eine solche, die an einer hier nicht näher dargestellten Frontplatte eines Gerätes mit Hilfe einer Überwurfmutter 9 festgeschraubt werden kann. Dabei stützt sich das Gehäuse 8 mit einem Flanschrand 10 auf der Rückseite der Frontplatte ab. Um eine gute Masseverbindung zwischen dem Gehäuse 8 und der nicht dargestellten Frontplatte zu erreichen, ist am Flanschrand 10 eine umlaufende Ringschneide 11 vorgesehen, die sich beim Anziehen der Überwurfmutter 9 in die Rückseite der nicht dargestellten Frontplatte einschneidet.This is an essentially rotationally symmetrical socket which, on its right-hand side, as shown in FIG. 1, has its plug-in side 1, via which contact is made with a plug (not shown here). On the opposite side (left) is the cable connection side 2 of the connector half. On this side, the connector half has cylindrical connecting tubes 3 corresponding to the number of its poles. On their inner wall, the cylindrical connecting tubes 3 have four radially inwardly directed spring tongues distributed over their circumference. The spring tongues 4 yield radially outwards when a wire or strand end is inserted in order to hold the wire or strand end in a force-locking manner. The spring tongues 4 are arranged in such a way that they initially run from the free end of the connecting tubes 3, parallel to their axis and run towards one another at a distance from the free end. The spring tongues 4 end at a point where they are closest to each other. This results in a barb effect, which makes it difficult to pull out an inserted connector pin. It remains to be added that the connecting tubes 3 are embedded in an insulating body which is surrounded by the housing 8 of the box. The box shown in FIG. 1 is one that can be screwed onto a front plate of a device, not shown here, with the aid of a union nut 9. The housing 8 is supported with a flange 10 on the back of the front panel. To ensure a good earth connection between the housing 8 and the one not shown To reach the front plate, a circumferential annular cutting edge 11 is provided on the flange edge 10, which cuts into the back of the front plate, not shown, when the union nut 9 is tightened.

Die Dose ist mit Befilterung versehen. Hierzu sind in die Anschlußröhrchen 3, von denen nur eines dargestellt ist, Röhrchenfilter 12 eingesteckt. Diese Röhrchenfilter 12 weisen zumindest auf der Seite, auf der sie in die Anschlußröhrchen 3 eingeschoben werden, einen dem Innendurchmesser der Anschlußröhrchen 3 angepaßten Anschlußstift 13 auf. Bei dem hier gezeigten Ausführungsbeispiel ist auch die andere Seite des Röhrchenfilters 12 mit einem Stift versehen, an den Leitungen angelötet werden können. Es ist jedoch günstig, an dieser Seite auch Anschlußröhrchen vorzusehen.The can is provided with filtering. For this purpose, tube filters 12 are inserted into the connecting tubes 3, only one of which is shown. These tube filters 12 have, at least on the side on which they are inserted into the connecting tubes 3, a connecting pin 13 matched to the inside diameter of the connecting tubes 3. In the exemplary embodiment shown here, the other side of the tube filter 12 is also provided with a pin to which lines can be soldered. However, it is favorable to also provide connecting tubes on this side.

Die Röhrchenfilter 12 werden von einer gemeinsamen Massescheibe 14 umgeben, die zu diesem Zweck mit Durchbrüchen versehen ist, an deren Enden zur Steckseite 1 der Dose gerichtete und aufeinander zu laufende Federkrallen 15 vorgesehen sind. Die Massescheibe 14 wird über einen Anpreßring 16 gegen eine radial nach innen gerichtete ringsumlaufende Schulter 17 des Gehäuses 8 gedrückt. Der Anpreßring 16 selbst wiederum wird dadurch gehalten, daß der kabelanschlußseitige frei endende Rand 18 des Gehäuses 8 umgebördelt ist. Auf seiner radial innen liegenden Seite weist der Anpreßring 16 eine Schrägfläche auf, mit der er eine radial innen liegende Führungsplatte 19 für die Röhrchenfilter 12 in Position hält. Diese Führungsplatte 19, die aus einem isolierenden Kunststoff besteht, kann auch, wie in Fig. 1 nicht dargestellt ist, mit der Massescheibe 14, z.B. durch Ultraschallvernieten, verbunden sein. Die Führungsplatte 19 weist einzelne Durchgangsbohrungen 20 auf, deren Innendurchmesser größer ist als der Außendurchmesser der Röhrchenfilter 12, so daß die Röhrchenfilter 12 durch die Durchgangsbohrungen 20 und die Federkrallen 15 der Massescheibe 14 hindurch in die Anschlußröhrchen 3 eingesteckt werden können.The tubular filters 12 are surrounded by a common ground disk 14, which is provided with openings for this purpose, at the ends of which spring claws 15 which are directed towards one another and which run towards one another are provided. The mass disk 14 is pressed via a pressure ring 16 against a radially inwardly directed circumferential shoulder 17 of the housing 8. The pressure ring 16 itself is held in that the free end 18 of the housing 8 is flanged. On its radially inner side, the pressure ring 16 has an inclined surface with which it holds a radially inner guide plate 19 for the tube filter 12 in position. This guide plate 19, which consists of an insulating plastic, can also, as is not shown in FIG. 1, with the ground disk 14, for example by ultrasonic riveting. The guide plate 19 has individual through bores 20, the inside diameter of which is greater than the outside diameter of the tubular filter 12, so that the tubular filter 12 can be inserted through the through bores 20 and the spring claws 15 of the ground disk 14 into the connecting tube 3.

Die außen liegende Stirnseite der Führungsplatte wird durch einen Deckel 21 abgedeckt, der zu den Durchgangsbohrungen 20 der Führungsplatte konzentrisch angeordnete Öffnungen 22 aufweist, deren Durchmsser kleiner ist als der Durchmesser der Röhrchenfilter 12. Der Deckel 21 wird durch einen an seinem Rand ausgebildeten und umlaufenden Halteclip 23 gehalten, der in eine Hinterschneidung 24 der Führungsplatte 12 eingreift.The outer end face of the guide plate is covered by a cover 21 which has openings 22 which are arranged concentrically with the through bores 20 of the guide plate and whose diameter is smaller than the diameter of the tube filter 12. The cover 21 is formed by a retaining clip formed on its edge and encircling it 23 held, which engages in an undercut 24 of the guide plate 12.

Im folgenden wird nun die Wirkungs- und Funktionsweise des soeben anhand der Fig. 1 beschriebenen Ausführungsbeispiels näher erläutert.In the following, the effect and functionality of the embodiment just described with reference to FIG. 1 will now be explained in more detail.

Zunächst legt man die Massescheibe 14 und die Führungsplatte 19 auf die Schulter 17 auf und legt den Anpreßring 16 darüber. Über nicht dargestellte Codiernuten werden die Massescheibe 14 und die Führungsplatte 19 lagegerecht ausgerichtet, so daß ihre Öffnungen mit den Öffnungen der Anschlußröhrchen 3 der Dose fluchten. Dann wird der Rand 18 des Gehäuses 8 verbördelt. Anschließend kann man entsprechend der vorgesehenen Befilterung die Filterröhrchen 12 durch die Durchgangsbohrungen 20 der Führungsplatte 19 hindurch mit ihren Anschlußstiften 13 in die Anschlußröhrchen 3 einschieben. Wenn dieser Vorgang abgeschlossen ist, setzt man den Deckel 21 auf und clipt ihn mit dem Halteclip 23 fest. Die Röhrchenfilter 12 werden nun nicht nur kraftschlüssig durch die Federzungen 4 der Anschlußröhrchen 3 und die Federkrallen 15 der Massescheibe 14, sondern auch noch formschlüssig durch den Deckel 21 gehalten.First, place the mass plate 14 and the guide plate 19 on the shoulder 17 and place the pressure ring 16 over it. The ground disk 14 and the guide plate 19 are aligned in the correct position via coding grooves (not shown) so that their openings are aligned with the openings of the connecting tubes 3 of the can. Then the edge 18 of the housing 8 is crimped. Then you can insert the filter tubes 12 through the through holes 20 of the guide plate 19 with their connecting pins 13 into the connecting tubes 3 according to the filtering provided. When this process is complete, the lid 21 is put on and clips it with the retaining clip 23. The tube filters 12 are now not only held in a force-fitting manner by the spring tongues 4 of the connecting tubes 3 and the spring claws 15 of the mass disk 14, but also in a form-fitting manner by the cover 21.

Das Anschlußkabel kann nun in herkömmlicher Weise mit den nicht näher dargestellten Litzenenden an die aus dem Deckel 21 herausragenden Lötstifte der Röhrchenfilter 12 angelötet werden. Bevorzugt wird jedoch, daß, obgleich nicht dargestellt, die Röhrchenfilter 12 an dieser Seite ebenfalls Anschlußröhrchen tragen, so daß die Litzenenden der Kabel lediglich in diese Anschlußröhrchen eingesteckt zu werden brauchen.The connecting cable can now be soldered in a conventional manner with the stranded ends (not shown) to the soldering pins of the tubular filter 12 protruding from the cover 21. It is preferred, however, that, although not shown, the tube filters 12 also carry connecting tubes on this side, so that the stranded ends of the cables need only be inserted into these connecting tubes.

Soll die Befilterung des Steckers geändert werden, wird der Deckel 21 abgesprengt, wonach sich die einzelnen Röhrchenfilter 12 entgegen dem durch die Federkrallen und die Federzungen bewirkten Kraftschluß herausziehen lassen. Da die Massescheibe 14 von der Führungsplatte 19 abgestützt wird, geschieht dieser Vorgang, ohne daß irgendwelche Beschädigungen hervorgerufen werden. Im Anschluß daran kann die Dose, wie bereits oben beschrieben, neu oder geändert, d.h.mit geänderten Filterwerten oder Filterarten, befiltert werden.If the filtering of the plug is to be changed, the cover 21 is blown off, after which the individual tube filters 12 can be pulled out against the frictional connection caused by the spring claws and the spring tongues. Since the mass disk 14 is supported by the guide plate 19, this process takes place without causing any damage. Subsequently, as already described above, the can can be refiltered or changed, i.e. with changed filter values or filter types.
