- US 4,300,338 describes a method of manufacturing a coaxial cable.
- the shield of the prior art cable consists of strip-shaped conductor elements of different width, which are helically wound in opposite directions around the inner conductor and the dielectric. This creates a coaxial cable with incomplete shielding. This results in a stray field surrounding the cable whose parameters are dictated by the geometry of the incomplete shielding.
- a socket for a coaxial connector is previously known.
- This socket has a circular-cylindrical, sleeve-shaped outer plug, which consists of electrically insulating material. Inside the outer plug, a contact element with a resilient, electrically conductive wire is arranged.

- a particularly simple and cost-manufacturability of the socket according to the invention results from the fact that this has a consisting of electrically insulating material body, which is integrally formed with the outer connector, wherein the outer contact element is embedded as a metallic stamped and bent part in the body.
- the socket can be easily manufactured either as a cable jack or socket for housing installation.
- the contact strip of the outer contact element is inserted into a mounted on the outside of the outer plug helical groove in the socket according to the invention. In this way, it is ensured that the outer contact element is securely fixed to the outer plug, even if forces act on the contact strip of the outer contact element when inserting a plug into the socket in the axial direction.
- the inner contact element is embedded in a carrier body of electrically insulating material which is axially insertable into a corresponding bore of the base body.
- the carrier body which thus forms together with the inner contact element, the inner life of the socket, for example, can be inserted from behind into the main body of the socket, without the arranged at the front end of the socket outer connector must be dismantled.
- the pitch of the helix corresponds substantially to the length of the outer plug. Accordingly, by making it possible to contact the outer contact element on the outer surface of the outer plug in the circumferential direction at any point and to minimize the total area of the contact strip made of electrically conductive material, it is ensured that the capacitance of the bushing is as low as possible and that the jack is also compatible with any commercially available RCA plug.

This ensures on the one hand a flat contact of the clamping tongues on the outer plug of the socket, which is advantageous for the mechanical stability of the connection between the plug and socket. Further, if the contact tongue and the clamping tongues have on their outer sides conically shaped end portions, this is advantageous for the contact pressure of the contact tongue and the clamping tongues against the outer surface of the outer plug of the socket.
- the clamping sleeve comes with its inner surface in the region of the conically shaped end portions on the outer sides of the contact tongue and the clamping tongues to the plant and is clamped in the axial direction against the plug body.
- the clamping sleeve consists of a base member and a ring member which is rotatably mounted on the base member, wherein the ring member with its inside at the conically shaped end portions the contact tongue and the clamping tongues attacks.
- the clamping tongues are formed on the plug body.
- the plug body and the clamping tongues may for example consist of anodized aluminum.
- This material is electrically insulating and has a particularly hard surface, which is advantageous in terms of occurring at the clamping tongues wear.
- the clamping tongues may also be formed on the carrier element for the inner contact pin. It is possible to fix the clamping tongues by means of a releasable latching or plug connection to the support element. Since the carrier element can be made of plastic material, it is not excluded that the molded on the support member clamping tongues break off inappropriate handling of the plug. It is accordingly useful if the terminal tongues can be replaced by means of the releasable latching or plug connection.
- the outer contact element of the plug by means of a releasable latching or plug connection to the support member can be fixed.
- the outer contact element is replaceable, which can be exploited, for example, to use outer contact elements with different large contact tongues to vary the impedance of the connector and so to optimize the adaptation to the characteristic impedance of the cable used.
- the outer contact element can be detached from the support element, for example, to solder the outer contact element with a cable. It is thereby avoided that the possibly made of a low-melting plastic material carrier element is destroyed by the heat transferred during soldering via the external contact element.

Description
Die Erfindung betrifft eine Buchse für eine koaxiale elektrische Steckverbindung, mit einer Innenkontaktöffnung, einem darin angeordneten Innenkontaktelement und mit einem die Innenkontaktöffnung umgebenden, kreiszylindrisch ausgebildeten Außenstecker aus elektrisch isolierendem Material, welcher ein Außenkontaktelement aufweist.The invention relates to a socket for a coaxial electrical plug-in connection, having an inner contact opening, an inner contact element arranged therein and having a circular-cylindrical outer plug of electrically insulating material surrounding the inner contact opening and having an outer contact element.
Des weiteren betrifft die Erfindung einen elektrischen Verbindungsstecker mit einem Steckerkörper, an dem ein elektrisch isolierendes Trägerelement für einen Innenkontaktstift befestigt ist, und mit einem von dem Innenkontaktstift in Bezug auf die Längsachse des Steckers radial beabstandeten Außenkontaktelement.Furthermore, the invention relates to an electrical connector with a plug body to which an electrically insulating support member is fixed for an inner contact pin, and with a radially spaced from the inner contact pin with respect to the longitudinal axis of the plug outer contact element.
Derartige koaxiale Steckverbinder sind unter der Bezeichnung "Cinch-Stecker" oder auch "RCA-Stecker" bekannt und dienen zur Herstellung einer lösbaren Kabelverbindung zwischen Geräten der Unterhaltungselektronik zum Zwecke der asymmetrischen Übertragung eines Audiosignals oder eines Videosignals. Herkömmliche RCA-Stecker weisen üblicherweise einen hohlzylindrisch ausgebildeten, koaxial zu dem Innenkontaktstift angeordneten Außenkontakt auf. Dieser Außenkontakt besteht in der Regel aus einem ringförmigen Metallstreifen, welcher in axialer Richtung verlaufende Schlitze aufweist. Mittels dieses geschlitzten Metallstreifens rastet der Stecker an dem ebenfalls kreiszylindrisch ausgebildeten Außenstecker einer zugehörigen Cinch- oder RCA-Buchse ein. Zur Herstellung einer kraftschlüssigen Verbindung des Steckers mit der Buchse werden bei derartigen RCA-Steckverbindungen die federelastischen Eigenschaften des geschlitzten Metallstreifens des Außenkontakts ausgenutzt.Such coaxial connectors are known as "RCA plugs" or "RCA plugs" known and are used to make a detachable cable connection between consumer electronics devices for the purpose of asymmetric transmission of an audio signal or a video signal. Conventional RCA plugs usually have a hollow cylindrical, coaxial with the inner contact pin arranged external contact. This external contact is usually made of an annular metal strip, which has slits extending in the axial direction. By means of this slotted metal strip of the plug engages the likewise circular cylindrical outer plug of an associated RCA or RCA socket. To produce a frictional connection of the plug with the socket are used in such RCA connectors, the resilient properties of the slotted metal strip of the external contact.
Aus der EP 1 049 206 A2 ist eine Buchse für eine koaxiale elektrische Steckverbindung bekannt, welche ein kreiszylindrisch ausgebildetes Außenkontaktelement aufweist. An der Innenseite des Außenkontaktelementes ist ein federelastischer Kontaktdraht angebracht, dessen Verlauf an der Innenseite des Außenkontaktelementes helixförmig sein kann. Durch den Kontaktdraht wird die Einsteck- und Auszugskraft bei der Verbindung der vorbekannten Buchse mit einem entsprechenden Stecker bestimmt.From
Eine Einbaubuchse für eine koaxiale elektrische Steckverbindung ist des Weiteren aus der JP 08-306443 A bekannt. Bei dieser Buchse ist ebenfalls das Außenkontaktelement insgesamt kreiszylindrisch ausgebildet, wobei auf der Außenseite des Außenkontaktelementes Erhebungen vorgesehen sind, die auf der Außenseite des Außenkontaktelementes kreisringförmig oder nach Art einer unterbrochenen Schraubenlinie verlaufen. Durch diese Erhebungen sollen die Kontakteigenschaften des Außenkontaktelementes der Buchse mit dem entsprechenden Außenkontaktelement eines zugehörigen Steckers verbessert werden.A female connector for a coaxial electrical connector is further known from JP 08-306443 A. In this socket, the outer contact element is also formed as a whole circular cylindrical, wherein elevations are provided on the outer side of the outer contact element, which extend on the outside of the outer contact element annular or in the manner of an interrupted helix. These projections are intended to improve the contact properties of the outer contact element of the socket with the corresponding outer contact element of an associated plug.
Eine weitere Buchse zur Aufnahme eines Koaxialsteckers ist aus der DE 199 08 469 A1 bekannt. Der in die vorbekannte Buchse einzusteckende Stecker weist eine umlaufende Nut auf, so dass es zu einem Verrasten des Steckers in der Buchse kommt.Another socket for receiving a coaxial connector is known from DE 199 08 469 A1. The plugged into the previously known connector has a circumferential groove, so that it comes to a locking of the plug in the socket.
Ferner ist aus der DE 199 27 713 C1 ein Mehrfachkuppler für koaxiale geschirmte Buchsen bekannte, welcher für den Einsatz in der Hochfrequenztechnik bestimmt ist. Bei dem vorbekannten Kuppler ist eine Spanneinrichtung vorgesehen, die dazu dient, die Kontaktierung bewirkende Klemmkräfte zwischen federnden Kontaktelementen der Stecker und den dazu korrespondierenden Außenkontaktelementen der zu kontaktierenden Buchsen aufzubringen.Furthermore, from DE 199 27 713 C1 discloses a multiple coupler for coaxial shielded sockets, which is intended for use in high-frequency engineering.

Es ist bekannt, dass Steckverbindungen der vorbeschriebenen Art suboptimale Eigenschaften im Hinblick auf die Qualität der Übertragung von Audio- und Videosignalen haben. Die koaxiale Anordnung aus Innenkontaktstift und Außenkontakt bestimmt wesentlich die Impedanz bei üblichen Steckverbindungen. Dabei ist vor allem problematisch, dass die Impedanz des Steckers in keiner Weise an den Wellenwiderstand des verwendeten Kabels angepaßt ist, so dass es zu Reflektionen des übertragenen Signals an der Verbindungsstelle kommt. Besonders relevant wird dieses Problem, wenn über die Steckverbindung digitale Audio- oder Videosignale mit einer hohen Datenrate übertragen werden. Es kann in diesem Fall aufgrund von nichtlinearen Signalverzerrungen zu Bitfehlern und erheblichen Datenverlusten kommen, so dass die Qualität der Wiedergabe der über die Steckverbindung übertragenen Audio- oder Videosignale stark herabgesetzt ist. Nachteiligerweise kommt es aber bereits bei der Übertragung von analogen Audio- und Videosignalen zu linearen Verzerrungen, welche sich spürbar auf die Qualität der Wiedergabe auswirken. Desweiteren ist bekannt, dass sich durch den Stromfluss über den Innenkontaktstift in dem kreiszylindrischen Metallstreifen des Außenkontaktes induzierte Wirbelströme bilden können, die in schwer vorhersehbarer Weise mit dem Signal interferieren und so die Signalübertragung beeinträchtigen.It is known that connectors of the type described above have sub-optimal characteristics with regard to the quality of the transmission of audio and video signals. The coaxial arrangement of inner contact pin and outer contact significantly determines the impedance in conventional connectors. It is especially problematic that the impedance of the plug is in no way adapted to the characteristic impedance of the cable used, so that it comes to reflections of the transmitted signal at the junction. This problem becomes particularly relevant when digital audio or video signals with a high data rate are transmitted via the plug connection. In this case, due to non-linear signal distortion, bit errors and significant data loss may occur, so that the quality of reproduction of the audio or video signals transmitted through the connector is greatly reduced. Unfortunately, even when transmitting analog audio and video signals, linear distortion occurs, which has a noticeable effect on the quality of the reproduction. Furthermore, it is known that can be formed by the current flow through the inner contact pin in the circular cylindrical metal strip of the external contact induced eddy currents, which interfere with the signal in a difficult predictable manner and thus affect the signal transmission.

Daraus resultiert ein das Kabel umgebendes Streufeld, dessen Parameter durch die Geometrie der unvollständigen Abschirmung vorgegeben sind.US 4,300,338 describes a method of manufacturing a coaxial cable. The shield of the prior art cable consists of strip-shaped conductor elements of different width, which are helically wound in opposite directions around the inner conductor and the dielectric. This creates a coaxial cable with incomplete shielding. This results in a stray field surrounding the cable whose parameters are dictated by the geometry of the incomplete shielding.
Aus der EP 1 049 206 A2 ist eine Buchse für eine koaxiale Steckverbindung vorbekannt. Diese Buchse weist einen kreiszylindrisch ausgebildeten, hülsenförmigen Außenstecker auf, der aus elektrisch isolierendem Material besteht. Im Inneren des Außensteckers ist ein Kontaktelement mit einem federnden, elektrisch leitenden Draht angeordnet.From
Aus der WO 00/70717 ist ein RCA-Stecker bekannt, welcher es ermöglicht, eine Steckverbindung mit einer üblichen RCA-Buchse herzustellen, wobei die zuvor skizzierten Nachteile zum Teil vermieden werden.From WO 00/70717 an RCA plug is known, which makes it possible to produce a plug connection with a conventional RCA socket, the disadvantages outlined above are partly avoided.
Der vorbekannte RCA-Stecker weist statt des üblichen geschlitzten Metallstreifens ein axial ausgerichteten, stiftförmig ausgebildetes Außenkontaktelement auf, welches relativ zu dem Innenkontaktstift mittels eines Trägerelements aus Plastikmaterial in einer für die Herstellung des elektrischen Kontakts erforderlichen Funktionsstellung festgelegt wird. Zur Halterung des Steckers an der zugehörigen Buchse ist an das Trägerelement ein ebenfalls aus Plastikmaterial bestehender Kragenabschnitt angeformt, welcher an dem kreiszylindrischen Außenkontakt der Buchse einrastet. Der stiftförmige Außenkontakt ist in das Plastikmaterial des Kragenabschnitts eingebettet, so dass der Kontaktstift beim Einstecken des Steckers in die Buchse von außen gegen den Außenkontakt der Buchse gepreßt wird. Der stiftförmige Außenkontakt ist bei dem vorbekannten RCA-Stecker in seinem Kontaktbereich zylinderförmig oder auch kugel- oder ellipsoidförmig ausgebildet.The prior art RCA plug has, instead of the usual slotted metal strip on an axially aligned, pin-shaped outer contact element, which is set relative to the inner contact pin by means of a support element made of plastic material in a required for the production of electrical contact functional position. For holding the plug to the associated socket, a likewise made of plastic existing collar portion is integrally formed on the support member, which engages the circular cylindrical outer contact of the socket. The pin-shaped outer contact is embedded in the plastic material of the collar portion, so that the contact pin is pressed during insertion of the plug into the socket from the outside against the outer contact of the socket. The pin-shaped outer contact is formed in the prior art RCA connector in its contact area cylindrical or spherical or ellipsoidal.
Zwar ist das Impedanzverhalten des aus der genannten Druckschrift bekannten RCA-Steckers deutlich anders als bei den oben beschriebenen herkömmlichen RCA-Steckern, was insbesondere auf den Verzicht auf den bisher üblichen koaxial zu dem Innenkontaktstift angeordneten Metallstreifen als Massekontakt zurückzuführen ist. Bei der Herstellung einer elektrischen Steckverbindung mit einem RCA-Stecker dieser Art besteht jedoch das Problem, dass auf Seiten der Buchse, in die der Stecker eingesteckt wird, nach wie vor die oben beschriebenen negativen Eigenschaften gegeben sind. Die Innenkontaktöffnung, in der sich der Innenkontaktstift des in die Buchse eingesteckten Steckers befindet, ist bei einer herkömmlichen RCA-Buchse nämlich vollständig von dem das Außenkontaktelement bildenden, metallischen Körper des Außensteckers der Buchse umgeben. Der kreiszylindrische Metallmantel des Außensteckers bestimmt wesentlich die nicht unerhebliche Kapazität der Steckverbindung. Außerdem können in dem metallischen Mantel des Außensteckers die oben beschriebenen Wirbelströme induziert werden, die sich negativ auf die Signalübertragung auswirken.Although the impedance behavior of the mentioned RCA connector is significantly different than in the conventional RCA plugs described above, which is due in particular to the waiver of the usual coaxial with the inner pin arranged metal strip as ground contact. In the manufacture of an electrical connector with an RCA connector of this type, however, there is the problem that on the side of the socket into which the plug is inserted, the above-described negative properties are still given. The inner contact opening in which the inner contact pin of the plug inserted into the socket is, in a conventional RCA socket namely completely surrounded by the outer contact element forming metallic body of the outer plug of the socket. The circular cylindrical metal shell of the outer connector significantly determines the not inconsiderable capacity of the connector. In addition, in the metallic shell of the outer plug, the above-described Eddy currents are induced, which have a negative effect on the signal transmission.
Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabenstellung zugrunde, eine koaxiale Steckverbindung bereit zu stellen, bei der die beschriebenen Nachteile und Probleme soweit wie möglich vermieden werden. Insbesondere soll durch die Erfindung eine Buchse für eine koaxiale elektrische Steckverbindung geschaffen werden, welche einen im Hinblick auf die Signalübertragung zwischen Geräten der Unterhaltungselektronik verbessertes Impedanzverhalten aufweist und bei welcher insbesondere das Auftreten von Wirbelströmen auf dem Außenkontaktelement vermieden wird.Against this background, the present invention has for its object to provide a coaxial connector, in which the disadvantages and problems described are avoided as much as possible. In particular, to be provided by the invention, a socket for a coaxial electrical connector, which has an improved in terms of signal transmission between devices of consumer electronics impedance behavior and in which in particular the occurrence of eddy currents is avoided on the outer contact element.
Diese Aufgabenstellung wird ausgehend von einer Buchse der eingangs genannten Art dadurch gelöst, dass das Außenkontaktelement des Außensteckers in seinem Kontaktbereich als Kontaktstreifen ausgebildet ist, dessen Verlauf auf der Außenfläche des Außensteckers eine kreiszylindrische Schraubenlinie bildet.This object is achieved on the basis of a socket of the type mentioned above in that the outer contact element of the outer plug is formed in its contact region as a contact strip whose course forms a circular cylindrical helix on the outer surface of the outer plug.
Gemäß der Erfindung wird der bei herkömmlichen RCA-Steckern übliche kreiszylindrisch ausgebildete Metallmantel durch den aus elektrisch isolierendem Material bestehenden Außenstecker ersetzt. Zur Herstellung des elektrischen Kontakts mit dem Außenkontaktelement eines Steckers dient der schraubenlinienförmige Kontaktstreifen der erfindungsgemäßen Buchse, welcher auf der Außenfläche des Außensteckers angeordnet ist. Auf diese Weise wird die Fläche des koaxial zu der Innenkontaktöffnung der Buchse angeordneten Außenkontaktelements minimiert, was zu einer deutlichen Reduzierung der Kapazität führt. Dadurch dass das Außenkontaktelement schraubenlinienförmig ausgebildet ist, ist eine Kontaktierung überall auf dem Außenumfang des Außensteckers möglich, wodurch sichergestellt ist, dass die Buchse zusammen mit herkömmlichen RCA-Steckern verwendet werden kann. Die erfindungsgemäße Ausbildung des Außenkontaktelements verhindert jedoch, dass sich in diesem Wirbelströme bilden können, da das Außenkontaktelement - anders als bei herkömmlichen RCA-Buchsen - keinen die Innenkontaktöffnung umgebenden zusammenhängenden flächigen Metallkörper bildet.According to the invention, the usual conventional RCA plugs circular cylindrical metal jacket is replaced by the existing of electrically insulating material male connector. To produce the electrical contact with the outer contact element of a plug, the helical contact strip of the socket according to the invention, which serves on the outer surface of the outer plug is arranged. In this way, the area of the outer contact element disposed coaxially with the inner contact opening of the socket is minimized, resulting in a significant reduction in capacitance. Characterized in that the outer contact element is helical, a contacting is possible anywhere on the outer circumference of the outer plug, thereby ensuring that the socket can be used together with conventional RCA plugs. However, the inventive design of the outer contact element prevents eddy currents can form in this, since the outer contact element - unlike conventional RCA sockets - does not form the inner contact opening surrounding contiguous sheet metal body.
Eine besonders einfache und kostengünstige Herstellbarkeit der erfindungsgemäßen Buchse ergibt sich dadurch, dass diese einen aus elektrisch isolierendem Material bestehenden Grundkörper aufweist, der mit dem Außenstecker einstückig ausgebildet ist, wobei das Außenkontaktelement als metallisches Stanzbiegeteil in den Grundkörper eingebettet ist. Auf diese Weise kann die Buchse problemlos entweder als Kabelbuchse oder als Buchse für den Gehäuseeinbau hergestellt werden.A particularly simple and cost-manufacturability of the socket according to the invention results from the fact that this has a consisting of electrically insulating material body, which is integrally formed with the outer connector, wherein the outer contact element is embedded as a metallic stamped and bent part in the body. In this way, the socket can be easily manufactured either as a cable jack or socket for housing installation.
Zweckmäßigerweise wird bei der erfindungsgemäßen Buchse der Kontaktstreifen des Außenkontaktelements in eine an der Außenseite des Außensteckers angebrachte schraubenförmige Nut eingelegt. Auf diese Weise ist gewährleistet, dass das Außenkontaktelement sicher an dem Außenstecker fixiert ist, auch wenn beim Einstecken eines Steckers in die Buchse in axialer Richtung Kräfte auf den Kontaktstreifen des Außenkontaktelements einwirken.Conveniently, the contact strip of the outer contact element is inserted into a mounted on the outside of the outer plug helical groove in the socket according to the invention. In this way, it is ensured that the outer contact element is securely fixed to the outer plug, even if forces act on the contact strip of the outer contact element when inserting a plug into the socket in the axial direction.
Es ist des weiteren vorteilhaft für die einfache und kostengünstige Herstellung der erfindungsgemäßen Buchse, wenn das Innenkontaktelement in einen Trägerkörper aus elektrisch isolierendem Material eingebettet ist, welcher in eine entsprechende Bohrung des Grundkörpers axial einsetzbar ist. Der Trägerkörper, der demgemäß zusammen mit dem Innenkontaktelement das Innenleben der Buchse bildet, kann beispielsweise von hinten in den Grundkörper der Buchse eingesetzt werden, ohne dass der am vorderen Ende der Buchse angeordnete Außenstecker demontiert werden muß.It is also advantageous for the simple and cost-effective production of the socket according to the invention, when the inner contact element is embedded in a carrier body of electrically insulating material which is axially insertable into a corresponding bore of the base body. The carrier body, which thus forms together with the inner contact element, the inner life of the socket, for example, can be inserted from behind into the main body of the socket, without the arranged at the front end of the socket outer connector must be dismantled.
Besonders sinnvoll ist es, wenn bei der erfindungsgemäßen Buchse die Ganghöhe der Schraubenlinie im wesentlichen der Länge des Außensteckers entspricht. Dadurch dass demgemäß eine Kontaktierung des Außenkontaktelements auf der Außenfläche des Außensteckers in Umfangsrichtung an jeder beliebigen Stelle möglich ist und dass die Gesamtfläche des aus elektrisch leitendem Material bestehenden Kontaktstreifens minimiert wird, ist dafür gesorgt, dass die Kapazität der Buchse so gering wie möglich ist und dass die Buchse außerdem zu jedem im Handel erhältlichen RCA-Stecker kompatibel ist.It is particularly useful if in the socket according to the invention, the pitch of the helix corresponds substantially to the length of the outer plug. Accordingly, by making it possible to contact the outer contact element on the outer surface of the outer plug in the circumferential direction at any point and to minimize the total area of the contact strip made of electrically conductive material, it is ensured that the capacitance of the bushing is as low as possible and that the jack is also compatible with any commercially available RCA plug.
Es ist zweckmäßig, bei der erfindungsgemäßen Buchse das Innenkontaktelement und/oder das Außenkontaktelement aus hoch leitfähigem Elektrolyt-Kupfer herzustellen. Dadurch ergibt sich eine besonders rauscharme Verbindung, und Signalverluste werden minimiert.It is expedient to produce the inner contact element and / or the outer contact element of highly conductive electrolyte-copper in the socket according to the invention. This results in a particularly low-noise connection, and signal losses are minimized.
Besonders zweckmäßig ist es, das elektrisch isolierende Material des Außensteckers einzufärben, da sich bei Geräten der Unterhaltungselektronik eine bestimmte Farbkodierung für die Zuordnung der Anschlüsse durchgesetzt hat. So ist es beispielsweise üblich, die Farben rot und weiß bei stereophonen Audiosignalen für den rechten bzw. linken Kanal zu verwenden. Die Farbe gelb bezeichnet einen Videoanschluss.It is particularly useful to color the electrically insulating material of the outer plug, since in consumer electronic devices a certain color coding for the assignment of the connections has prevailed. For example, it is common to use the colors red and white in stereo audio signals for the right and left channels, respectively. The color yellow indicates a video connection.
Ferner ist es bei der erfindungsgemäßen Buchse sinnvoll, wenn der Außenstecker und/oder der Grundkörper aus PTFE-Kunststoffmaterial bestehen. Dieses unter der Marke "Teflon" gehandelte Material ist besonders temperaturbeständig, was vorteilhaft ist, wenn beispielsweise an dem Außenkontaktelement eine elektrische Leitung durch Löten befestigt wird. Die dabei entstehende Aufheizung des Außenkontaktelements könnte bei Verwendung eines weniger temperaturbeständigen Kunststoffs dazu führen, dass der Außenstecker bzw. der Grundkörper der Buchse beschädigt werden. Andere temperaturbeständige Kunststoffe, wie beispielsweise PEEK-Materialien, kommen ebenfalls in Frage.Furthermore, it makes sense in the socket according to the invention, when the outer plug and / or the base body made of PTFE plastic material. This traded under the brand "Teflon" material is particularly resistant to temperature, which is advantageous if, for example, at the outer contact element, an electrical line is fixed by soldering. The resulting heating of the outer contact element could result in the use of a less temperature-resistant plastic cause the outer plug or the main body of the socket to be damaged. Other temperature-resistant plastics, such as PEEK materials, are also suitable.
Eine vorteilhafte Weiterbildung der erfindungsgemäßen Buchse besteht darin, dass der Kontaktstreifen auf der Außenfläche des Außensteckers in zwei oder mehr Helixabschnitte unterteilt ist, welche über Kontaktstege mit einer Lötlasche verbunden sind. Diese Ausgestaltung ist fertigungstechnisch besonders günstig, wenn das Außenkontaktelement als metallisches Stanzbiegeteil hergestellt wird. Die erfindungsgemäße Schraubenlinienform des Kontaktstreifens liegt dann in Form der zwei oder mehr Helixabschnitte vor, wobei die oben beschriebenen technischen Vorteile ebenso erreicht werden wie im Falle einer durchgehenden Schraubenlinienform des Kontaktstreifens.An advantageous development of the socket according to the invention is that the contact strip is divided on the outer surface of the outer plug into two or more helix sections, which are connected via contact webs with a solder tab. This embodiment is particularly favorable in terms of production engineering, when the external contact element is produced as a metallic stamped and bent part. The inventive helical shape of the contact strip is then in the form of two or more helix sections, wherein the technical advantages described above are achieved as well as in the case of a continuous helical shape of the contact strip.
Um die der Erfindung zugrunde liegende Aufgabenstellung, nämlich eine gegenüber dem Stand der Technik verbesserte koaxiale Steckverbindung zu schaffen, zu lösen, ist es erforderlich, nicht nur eine geeignete Buchse, sondern auch einen dazu passenden elektrischen Verbindungsstecker bereitzustellen, da die für die Signalübertragung relevanten Eigenschaften der Verbindung durch das aus Stecker und Buchse bestehende Gesamtsystem bestimmt werden.In order to solve the object underlying the invention, namely to provide a coaxial connector which is improved over the prior art, it is necessary to provide not only a suitable socket, but also a matching electrical connector, since the properties relevant to signal transmission the connection can be determined by the overall system consisting of plug and socket.
Ausgehend von einem elektrischen Verbindungsstecker der eingangs beschriebenen Art löst die Erfindung die genannte Aufgabenstellung also ferner dadurch, dass das Außenkontaktelement des Steckers in seinem Kontaktbereich als elektrisch leitende Kontaktzunge ausgebildet ist, wobei zur Halterung des Steckers an einer Buchse von dem Innenkontaktstift radial beabstandete, elektrisch isolierende Klemmzungen vorgesehen sind, welche zusammen mit der Kontaktzunge mittels einer an dem Steckerkörper beweglich geführten Klemmhülse nach innen gegen die Außenfläche eines kreiszylindrisch ausgebildeten Außensteckers der Buchse gepreßt werden.Starting from an electrical connector of the type described above, the invention solves said task thus further characterized in that the outer contact element of the plug is formed in its contact region as an electrically conductive contact tongue, wherein for holding the plug to a socket radially spaced from the inner contact pin, electrically insulating Clamping tongues are provided, which are pressed together with the contact tongue by means of a movably guided on the plug body clamping sleeve inwardly against the outer surface of a circular cylindrical outer plug of the socket.
Der erfindungsgemäße Stecker ist zwar geeignet, für die Herstellung einer koaxialen Steckverbindung mit herkömmlichen RCA-Buchsen verwendet zu werden. Eine im Sinne der Erfindung verbesserte Steckverbindung kommt jedoch zustande, wenn der Stecker zusammen mit einer erfindungsgemäßen Buchse ein koaxiales Steckverbindungssystem bildet.Although the plug according to the invention is suitable to be used for the production of a coaxial connector with conventional RCA jacks. However, in the context of the invention improved connector comes off when the plug forms a coaxial connector system together with a socket according to the invention.
Bei dem erfindungsgemäßen Stecker wird als Außenkontaktelement die elektrisch leitende Kontaktzunge verwendet, so dass das Außenkontaktelement - anders als bei herkömmlichen RCA-Steckern - den Innenkontaktstift nicht vollständig umgibt. Dadurch wird wiederum die Kapazität der Steckverbindung reduziert und gleichzeitig das Auftreten von Wirbelströmen verhindert. Damit eine sichere Halterung des Steckers an der Buchse gewährleistet ist, sind elektrisch isolierende Klemmzungen vorgesehen, welche mittels der Klemmhülse gegen die Außenfläche des Außensteckers der Buchse gepreßt werden. Gemäß der Erfindung ist somit eine besonders feste kraftschlüssige Verbindung des Steckers mit der Buchse gewährleistet. Anders als bei dem aus der oben erwähnten WO 00/70717 bekannten Stecker, wird bei dem erfindungsgemäßen Stecker das Außenkontaktelement durch die Klemmhülse gewissermaßen aktiv gegen die Außenfläche des Außensteckers der Buchse gepreßt. Bei dem vorbekannten Stecker wird die für die Herstellung des elektrischen Kontakts benötigte Anpreßkraft ausschließlich durch das federelastische Plastikmaterial aufgebracht, in welches der stiftförmige Außenkontakt des Steckers eingebettet ist. Bei der mechanischen Halterung des erfindungsgemäßen Steckers an der Buchse wirken die Kontaktzunge und die Klemmzungen, welche mittels der Klemmhülse gegen den Außenstecker der Buchse gepreßt werden, zusammen. Bei dem vorbekannten Stecker beruht die mechanische Halterung des Steckers an der Buchse wiederum allein auf der Federelastizität des Plastikmaterials. Durch die Erfindung wird somit ein sowohl in elektrischer als auch in mechanischer Hinsicht gegenüber dem Stand der Technik verbessertes koaxiales Steckverbindungssystem geschaffen.In the plug according to the invention, the electrically conductive contact tongue is used as the outer contact element, so that the outer contact element - unlike conventional RCA plugs - does not completely surround the inner contact pin. This in turn reduces the capacity of the connector while preventing the occurrence of eddy currents. So that a secure mounting of the plug is ensured on the socket, are electrically insulating clamping tongues provided, which are pressed by means of the clamping sleeve against the outer surface of the outer plug of the socket. According to the invention thus a particularly strong non-positive connection of the plug is ensured with the socket. Unlike the plug known from WO 00/70717 mentioned above, in the plug according to the invention, the outer contact element is pressed by the clamping sleeve effectively active against the outer surface of the outer plug of the socket. In the previously known connector, the contact pressure required for the production of the electrical contact is applied exclusively by the resilient plastic material, in which the pin-shaped outer contact of the plug is embedded. In the mechanical mounting of the plug according to the invention on the socket, the contact tongue and the clamping tongues, which are pressed by means of the clamping sleeve against the outer plug of the socket, together. In the prior art connector, the mechanical support of the plug on the socket in turn is based solely on the spring elasticity of the plastic material. The invention thus provides an improved both in electrical and in mechanical terms over the prior art coaxial connector system.
Ein besonderer Vorteil des erfindungsgemäßen Steckers besteht ferner darin, dass die Fläche der Kontaktzunge derart gewählt werden kann, dass die Impedanz der Steckverbindung an den Wellenwiderstand des verwendeten Kabels angepaßt ist. Die Fläche der Kontaktzunge beeinflußt nämlich maßgeblich die Impedanz des Steckers. Insbesondere wenn der erfindungsgemäße Stecker zusammen mit einer erfindungsgemäßen Buchse ein koaxiales Steckverbindungssystem bildet, kann bereits bei der Herstellung des Steckers durch geeignete Vorgabe der Fläche der Kontaktzunge für ein optimiertes Impedanzverhalten der koaxialen elektrischen Steckverbindung gesorgt werden.A particular advantage of the connector according to the invention further consists in that the surface of the contact tongue can be selected such that the impedance of the connector is adapted to the characteristic impedance of the cable used. The area of the contact tongue namely significantly affects the impedance of the plug. In particular, when the plug according to the invention forms a coaxial plug connection system together with a socket according to the invention, an optimized impedance behavior of the coaxial electrical plug connection can already be ensured during production of the plug by suitable predetermination of the surface of the contact tongue.
Eine sinnvolle Weiterbildung des erfindungsgemäßen Verbindungssteckers ergibt sich dadurch, dass die Kontaktzunge an ihrer Innenseite eine linienförmige Erhebung aufweist. Dabei wird über die linienförmige Erhebung der elektrische Kontakt mit dem Außenkontaktelement der Buchse an einer genau definierten Stelle hergestellt, was insbesondere vorteilhaft ist, wenn der Stecker zusammen mit einer erfindungsgemäßen Buchse verwendet wird. In diesem Fall überlappt sich die linienförmige Erhebung der Kontaktzunge und der schraubenlinienförmige Kontaktstreifen der Buchse an wenigstens einer Stelle auf der Außenfläche des Außensteckers der Buchse. Durch den Überlappungsbereich ist die Kontaktfläche der Steckverbindung präzise und reproduzierbar definiert, und insbesondere hängt die Impedanz der Steckverbindung nicht etwa davon ab, wie weit der Stecker in die Buchse eingesteckt wird.A useful development of the connector according to the invention results from the fact that the contact tongue has a line-shaped elevation on its inside. In this case, the electrical contact with the outer contact element of the socket is made at a precisely defined point on the linear survey, which is particularly advantageous when the plug is used together with a socket according to the invention. In this case overlaps the line-shaped elevation of the contact tongue and the helical contact strip of the socket at at least one point on the outer surface of the outer plug of the socket. Due to the overlap region, the contact surface of the connector is defined precisely and reproducibly, and in particular the impedance of the connector does not depend on how far the plug is plugged into the socket.
Um eine sichere Kontaktierung des schraubenlinienförmigen Kontaktstreifens der erfindungsgemäßen Buchse zu gewährleisten, ist es zweckmäßig, wenn auf Seiten des Steckers die Längsachse der Kontaktzunge und/oder die linienförmige Erhebung in Bezug auf die Längsachse des erfindungsgemäßen Verbindungssteckers schräg ausgerichtet sind. In diesem Fall ist es vorteilhaft, wenn sich die linienförmige Erhebung des Steckers und der Kontaktstreifen der Buchse unter einem Winkel von im wesentlichen 90° überlappen.In order to ensure a secure contacting of the helical contact strip of the socket according to the invention, it is expedient if the longitudinal axis of the contact tongue and / or the linear elevation are aligned obliquely with respect to the longitudinal axis of the connector according to the invention on the side of the plug. In this case, it is advantageous if the linear projection of the plug and the contact strip of the socket overlap at an angle of substantially 90 °.
Zweckmäßigerweise weisen bei dem erfindungsgemäßen Verbindungsstecker die Kontaktzunge und/oder die Klemmzungen einen an die kreiszylindrische Form des Außensteckers der Buchse angepasste Krümmung auf. Damit wird einerseits eine flächige Anlage der Klemmzungen an dem Außenstecker der Buchse gewährleistet, was für die mechanische Stabilität der Verbindung zwischen Stecker und Buchse vorteilhaft ist. Wenn ferner die Kontaktzunge und die Klemmzungen an ihren Außenseiten konisch geformte Endabschnitte aufweisen, ist dies vorteilhaft für die Anpressung der Kontaktzunge und der Klemmzungen gegen die Außenfläche des Außensteckers der Buchse. Hierzu kommt nämlich die Klemmhülse mit ihrer Innenfläche im Bereich der konisch geformten Endabschnitte an den Außenseiten der Kontaktzunge und der Klemmzungen zur Anlage und wird in axialer Richtung gegen den Steckerkörper verspannt. Um bei diesem Vorgang auftretenden Verschleiß an der Kontaktzunge und an den Klemmzungen zu vermeiden, ist es sinnvoll, wenn die Klemmhülse aus einem Grundelement und einem Ringelement besteht, welches drehbar an dem Grundelement gelagert ist, wobei das Ringelement mit seiner Innenseite an den konisch geformten Endabschnitten der Kontaktzunge und der Klemmzungen angreift.Conveniently, in the connector according to the invention, the contact tongue and / or the clamping tongues have a curvature adapted to the circular-cylindrical shape of the outer plug of the socket. This ensures on the one hand a flat contact of the clamping tongues on the outer plug of the socket, which is advantageous for the mechanical stability of the connection between the plug and socket. Further, if the contact tongue and the clamping tongues have on their outer sides conically shaped end portions, this is advantageous for the contact pressure of the contact tongue and the clamping tongues against the outer surface of the outer plug of the socket. For this purpose, namely the clamping sleeve comes with its inner surface in the region of the conically shaped end portions on the outer sides of the contact tongue and the clamping tongues to the plant and is clamped in the axial direction against the plug body. In order to avoid wear occurring in this process on the contact tongue and on the clamping tongues, it makes sense if the clamping sleeve consists of a base member and a ring member which is rotatably mounted on the base member, wherein the ring member with its inside at the conically shaped end portions the contact tongue and the clamping tongues attacks.
Eine kostengünstige und einfache Herstellbarkeit des elektrischen Verbindungssteckers gemäß der Erfindung ergibt sich, wenn die Klemmzungen an den Steckerkörper angeformt sind. In diesem Fall können der Steckerkörper und die Klemmzungen beispielsweise aus eloxiertem Aluminium bestehen. Dieses Material ist elektrisch isolierend und weist eine besonders harte Oberfläche auf, was vorteilhaft im Hinblick auf an den Klemmzungen auftretenden Verschleiß ist. Alternativ können die Klemmzungen auch an das Trägerelement für den Innenkontaktstift angeformt sein. Dabei besteht die Möglichkeit, die Klemmzungen mittels einer lösbaren Einrast- oder Steckverbindung an dem Trägerelement festzulegen. Da das Trägerelement aus Kunststoffmaterial bestehen kann, ist nicht ausgeschlossen, dass die an das Trägerelement angeformten Klemmzungen bei unsachgemäßer Handhabung des Steckers abbrechen. Es ist dementsprechend sinnvoll, wenn die Klemmzungen mittels der lösbaren Einrast- oder Steckverbindung ausgewechselt werden können.An inexpensive and easy manufacturability of the electrical connector according to the invention results when the clamping tongues are formed on the plug body. In this case, the plug body and the clamping tongues may for example consist of anodized aluminum. This material is electrically insulating and has a particularly hard surface, which is advantageous in terms of occurring at the clamping tongues wear. Alternatively, the clamping tongues may also be formed on the carrier element for the inner contact pin. It is possible to fix the clamping tongues by means of a releasable latching or plug connection to the support element. Since the carrier element can be made of plastic material, it is not excluded that the molded on the support member clamping tongues break off inappropriate handling of the plug. It is accordingly useful if the terminal tongues can be replaced by means of the releasable latching or plug connection.
Es ist ferner vorteilhaft, wenn auch das Außenkontaktelement des Steckers mittels einer lösbaren Einrast- oder Steckverbindung an dem Trägerelement festlegbar ist. Auf diese Weise ist das Außenkontaktelement auswechselbar, was beispielsweise ausgenutzt werden kann, um Außenkontaktelemente mit unterschiedlichen großen Kontaktzungen zu verwenden, um die Impedanz der Steckverbindung zu variieren und so die Anpassung an den Wellenwiderstand des verwendeten Kabels zu optimieren. Außerdem ist vorteilhaft, dass das Außenkontaktelement von dem Trägerelement gelöst werden kann, um beispielsweise das Außenkontaktelement mit einem Kabel zu verlöten. Es wird dadurch vermieden, dass das ggf. aus einem niedrigschmelzenden Kunststoffmaterial bestehende Trägerelement durch die beim Löten über das Außenkontaktelement übertragene Wärme zerstört wird.It is also advantageous if the outer contact element of the plug by means of a releasable latching or plug connection to the support member can be fixed. In this way, the outer contact element is replaceable, which can be exploited, for example, to use outer contact elements with different large contact tongues to vary the impedance of the connector and so to optimize the adaptation to the characteristic impedance of the cable used. In addition, it is advantageous that the outer contact element can be detached from the support element, for example, to solder the outer contact element with a cable. It is thereby avoided that the possibly made of a low-melting plastic material carrier element is destroyed by the heat transferred during soldering via the external contact element.
Im Sinne einer hohen mechanischen Stabilität der Verbindung zwischen Stecker und Buchse ist es zweckmäßig, wenn bei dem erfindungsgemäßen Verbindungsstecker die Klemmzungen und die Kontaktzunge am Außenumfang des Trägerelements in Umfangsrichtung gleichmäßig voneinander beabstandet angeordnet sind. Insbesondere wenn der Verbindungsstecker zwei Klemmzungen aufweist, ist zusammen mit der Kontaktzunge eine über drei Punkte erfolgende Anlage des Steckers an der Buchse gewährleistet. Durch diese Dreipunkt-Halterung ist sichergestellt, dass sowohl die beiden Klemmzungen als auch die Kontaktzunge durch die Klemmhülse gleichmäßig gegen den Außenstecker der Buchse gepreßt werden. Es ergibt sich somit eine unter mechanischen und elektrischen Gesichtspunkten sichere Verbindung.In terms of a high mechanical stability of the connection between the plug and socket, it is expedient if the clamping tongues and the contact tongue on the outer circumference of the support element in the circumferential direction uniformly spaced apart in the connector according to the invention. In particular, when the connector has two clamping tongues, together with the contact tongue over a three-point location of the connector is ensured at the socket. Through this three-point bracket It is ensured that both the two clamping tongues and the contact tongue are pressed by the clamping sleeve uniformly against the outer plug of the socket. It thus results in a secure mechanical and electrical connection.
Gemäß einer sinnvollen Weiterbildung der Erfindung weist der Verbindungsstecker eine Rastverbindung auf, mittels welcher das elektrisch isolierende Trägerelement an dem Steckerkörper lösbar befestigt ist. Daraus ergeben sich Vorteile bei der Montage des Verbindungssteckers und beim Anlöten eines Kabels an das Außenkontaktelement bzw. an den Innenkontaktstift.According to a useful development of the invention, the connector has a latching connection, by means of which the electrically insulating support member is releasably secured to the plug body. This results in advantages in the assembly of the connector and when soldering a cable to the outer contact element or to the inner contact pin.

Die Figuren 1, 2 und 3 zeigen eine für den Gehäuseeinbau bestimmte Buchse, welche als Ganzes mit der Bezugsziffer 1 bezeichnet ist. Die Buchse 1 weist am vorderen Ende eine Innenkontaktöffnung 2 auf, in welche der Innenkontaktstift eines zu der Buchse 1 passenden Steckers eingesteckt wird. Im Inneren der Innenkontaktöffnung 2 ist ein Innenkontaktelement 3 zur Herstellung des elektrischen Kontakts mit dem Innenkontaktstift des Steckers angeordnet. Die Innenkontaktöffnung 2 ist von einem kreiszylindrisch ausgebildeten Außenstecker 4 umgeben, welcher aus elektrisch isolierendem Material, beispielsweise aus PTFE-Kunststoffmaterial besteht. Der Außenstecker 4 ist mit einem Grundkörper 5 der Buchse 1 einstückig ausgebildet. Als Außenkontaktelement weist die Buchse 1 einen Kontaktstreifen 6 auf, dessen Verlauf auf der Außenfläche des Außensteckers 4 eine kreiszylindrische Schraubenlinie bildet.
