Abstract

PCT No. PCT/EP90/02017 Sec. 371 Date Aug. 22, 1991 Sec. 102(e) Date Aug. 22, 1991 PCT Filed Nov. 26, 1990 PCT Pub. No. WO91/10270 PCT Pub. Date Jul. 11, 1991.A clamping device for making an electrical connection has a tightening nut which can be screwed on a screw thread and on being axially adjusted exerts a clamping force on a component which cannot be axially moved, e.g., the end of a cable to be clamped. In order to permit particularly easy tightening and releasing in such a clamping device and prevent damage to the axially immovable component, the tightening nut is fitted on the clamping side with a separate pressure member transmitting the clamping force fitted on the clamping nut rotatably about the screw thread axis.

Description

Die Erfindung betrifft einen Cinch (RCA)-Stecker mit Klemmvorrichtung, bestehend aus einem Steckerkörper und einer in axialer Richtung aufschraubbaren, den Steckerkörper umgebenden Abdeckhülse, wobei der Steckerkörper an seiner Kontaktseite einen Kontaktstift und einen den Kontaktstift umgebenden, an seiner Außenseite konischen Außenringkontakt aufweist, der durch axial verlaufende Schlitze unterteilt ist und mittels der Abdeckhülse bei deren axialer Bewegung radial zusammenpreßbar ist. Ein derartiger Cinch (RCA)-Stecker ist beispielsweise aus der WO-A-86 03 895 bekannt. Die von der Klemmvorrichtung derartiger Cinch (RCA)-Stecker erzeugten radial gerichteten Klemmkräfte bewirken einen besonders festen und lockerungsfreien Halt des Außenringkontaktes am Außenringkontakt der zugehörigen Buchse.The invention relates to a cinch (RCA) connector with a clamping device, consisting of a connector body and a cover sleeve which can be screwed on in the axial direction and surround the connector body, the connector body having a contact pin on its contact side and an outer ring contact surrounding the contact pin and conical on the outside thereof. which is divided by axially extending slots and can be radially compressed by means of the cover sleeve during its axial movement. Such a cinch (RCA) connector is known for example from WO-A-86 03 895. The radially directed clamping forces generated by the clamping device of such cinch (RCA) plugs bring about a particularly firm and looseness-free hold of the outer ring contact on the outer ring contact of the associated socket.

Ein Nachteil des bekannten Cinch (RCA)-Steckers mit Klemmvorrichtung besteht darin, daß bei der Erzeugung der Klemmkraft eine starke, gegen die Drehbewegung der Abdeckhülse gerichtete Reibung zwischen der Außenseite des Außenringkontaktes und der Abdeckhülse auftritt. Durch diese Reibung bilden sich an der Außenseite des Außenringkontakes Riefen oder andere Beschädigungen aus, die z. B. zu einer Ablösung der Kontaktvergoldung führen können. Weiterhin behindert die Reibung die Drehbewegung der Außenhülse und beeinträchtigt somit den Spann- und Lösevorgang.A disadvantage of the known cinch (RCA) connector with a clamping device is that when the clamping force is generated, a strong friction against the rotational movement of the cover sleeve occurs between the outside of the outer ring contact and the cover sleeve. This friction causes scoring or other damage to form on the outside of the outer ring cone from the z. B. can lead to a detachment of the contact gold plating. Furthermore, the friction hinders the rotational movement of the outer sleeve and thus impairs the tensioning and loosening process.

Es ist deshalb Aufgabe der Erfindung, den Cinch (RCA)-Stecker mit Klemmvorrichtung der eingangs genannten Art dahingehend weiterzubilden, daß Riefen oder vergleichbare Beschädigungen an der Außenseite des Klemmringkontaktes vermieden werden und der Spann- und Lösevorgang erleichtert wird.It is therefore an object of the invention to further develop the cinch (RCA) connector with a clamping device of the type mentioned at the outset in such a way that scoring or comparable damage to the outside of the clamping ring contact is avoided and the tensioning and loosening process is facilitated.

Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend von dem Cinch (RCA)-Stecker der eingangs genannten Art vor, daß die Abdeckhülse kontaktseitig mit einem Ringelement versehen ist, welches drehbar am Hülsenkörper der Abdeckhülse gelagert ist und mit seiner Innenseite an der konischen Außenseite des Außenringkontaktes anliegt.To achieve this object, the invention proposes, starting from the cinch (RCA) connector of the type mentioned, that the cover sleeve is provided on the contact side with a ring element which is rotatably mounted on the sleeve body of the cover sleeve and with its inside on the conical outside of the outer ring contact is present.

Durch das um die Schraubachse der Abdeckhülse drehbar gelagerte Ringelement wird die den Schraubvorgang behindernde Reibung in Umfangsrichtung erheblich vermindert, so daß der Spann- und Lösevorgang entsprechend erleichtert wird. Da während des Spannvorganges eine Relativverschiebung in Umfangsrichtung zwischen dem feststehenden Außenringkontakt und dem Ringelement nicht mehr stattfindet, werden Riefen und sonstige Beschädigungen an dem Außenringkontakt weitestgehend vermieden.Due to the ring element rotatably mounted about the screw axis of the cover sleeve, the friction that hinders the screwing process is considerably reduced in the circumferential direction, so that the clamping and loosening process is correspondingly facilitated. Since there is no longer any relative displacement in the circumferential direction between the fixed outer ring contact and the ring element during the tensioning process, scoring and other damage to the outer ring contact are largely avoided.

Eine zweckmäßige Weiterbildung der Erfindung sieht vor, daß sich an das Ringelement ein rohrförmiges Teilstück anschließt, welches über die Lagerstelle hinaus in die Abdeckhülse hineinragt und etwa bis zur Lagerstelle mit einem oder mehreren in axialer Richtung verlaufenden Schlitzen versehen ist. Durch dieses rohrförmige Teilstück wird das Ringelement exakt an der Abdeckhülse geführt. Die in axialer Richtung verlaufenden Schlitze am rohrförmigen Teilstücke ermöglichen eine leichte und einfache Montage des Ringelementes in der zugehörigen Aufnahmeöffnung der Abdeckhülse.An expedient development of the invention provides that a tubular section adjoins the ring element, which extends beyond the bearing point into the cover sleeve and approximately to the bearing point one or more slots extending in the axial direction is provided. Through this tubular section, the ring element is guided exactly on the cover sleeve. The slots running in the axial direction on the tubular sections enable the ring element to be easily and simply installed in the associated receiving opening of the cover sleeve.

Zweckmäßig sind weiterhin die Abdeckhülse und das Ringelement außen mit einem isolierenden Überzug, insbesondere einer isolierenden Eloxalschicht versehen. Durch diese Isolierung werden unerwünschte Nebeneffekte vermieden, die besonders bei dicht nebeneinander angeordneten Cinch (RCA)-Steckern auftreten können.The cover sleeve and the ring element are also expediently provided on the outside with an insulating coating, in particular an insulating anodized layer. This insulation avoids undesirable side effects that can occur particularly when cinch (RCA) plugs are arranged close together.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Es zeigen:

einen Schnitt entlang der Linie II-II in Fig. 1.
An embodiment of the invention is explained below with reference to the drawing. Show it:
Fig. 1
a cinch (RCA) connector of the type according to the invention with connected cable in side view and partially in longitudinal section;
Fig. 2
a section along the line II-II in Fig. 1st

Der in der Zeichnung dargestellte Cinch (RCA)-Stecker weist einen Steckerkörper 1 auf, auf den eine Abdeckhülse 2 aufschraubbar ist. Diese Abdeckhülse 2 setzt sich aus einem Hülsenkörper 3 und einem Ringelement 4 zusammen, welches an einer Lagerstelle 5 drehbar mit dem Hülsenkörper 3 verbunden ist. An das Ringelement 4 schließt sich ein rohrförmiges Teilstück 6 an, welches über die Lagerstelle 5 hinaus in den Hülsenkörper 3 hineinragt.The cinch (RCA) connector shown in the drawing has a connector body 1 onto which a cover sleeve 2 can be screwed. This cover sleeve 2 is composed of a sleeve body 3 and a ring element 4 which is rotatably connected to the sleeve body 3 at a bearing 5. A tubular section 6 adjoins the ring element 4 and projects beyond the bearing point 5 into the sleeve body 3.

Etwa bis zur Lagerstelle 5 ist das rohrförmige Teilstück 6 mit einem oder mehreren in axialer Richtung verlaufenden Schlitzen 7 (dargestellt in Fig. 2) versehen. Diese Schlitze 7 dienen dazu, das Ringelement 4 mit seinem rohrförmigen Teilstück 6 zum Zwecke der Montage leicht in den Hülsenkörper 3 einsetzen zu können. Das rohrförmige Teilstücke 6 verleiht dem Ringelement 4 während des Verspannens und Lösens eine sichere und stabile Führung in dem Hülsenkörper 3.Approximately up to the bearing point 5, the tubular section 6 is provided with one or more slots 7 (shown in FIG. 2) extending in the axial direction. These slots 7 serve to enable the ring element 4 with its tubular section 6 to be easily inserted into the sleeve body 3 for the purpose of assembly. The tubular sections 6 give the ring element 4 a secure and stable guidance in the sleeve body 3 during tensioning and loosening.

An der Kontaktseite ist der Steckerkörper 1 mit einem Mittelkontaktstift 8 und einem diesen ringförmig umgebenden Außenringkontakt 9 versehen. Nach außen hin wird der gesamte Steckerkörper 1 über seine gesamte Länge von der Abdeckhülse 2 abgedeckt. Der Hülsenkörper 3 der Abdeckhülse 2 ist kabelanschlußseitig mit einem metallischen Innengewinde 10 versehen, welches auf ein entsprechendes metallisches Außengewinde 11 des Steckerkörpers 1 aufgeschraubt ist. Dieses metallische Außengewinde 11 steht über eine Brücke 12 mit dem Anschluß 13 für einen Abschirmleiter 14 eines Koaxialkabels 15 elektrisch leitend in Verbindung. Mittels einer Klemmschraube 16, die in der Zeichnung strichpunktiert dargestellt ist, wird das Koaxialkabel 15 fest im Stekkerkörper 1 gehalten. Ein weiterer Anschluß 17 des Koaxialkabels 15 steht in elektrischer Verbindung mit dem Kontaktstift 8.On the contact side, the plug body 1 is provided with a center contact pin 8 and an outer ring contact 9 surrounding it in a ring shape. Outwardly, the entire plug body 1 is covered by the cover sleeve 2 over its entire length. The sleeve body 3 of the cover sleeve 2 is provided on the cable connection side with a metallic internal thread 10, which is screwed onto a corresponding metallic external thread 11 of the connector body 1. This metallic external thread 11 is connected via a bridge 12 to the connection 13 for a shielding conductor 14 of a coaxial cable 15 in an electrically conductive manner. The coaxial cable 15 is held firmly in the connector body 1 by means of a clamping screw 16, which is shown in broken lines in the drawing. Another connection 17 of the coaxial cable 15 is in electrical connection with the contact pin 8.

Der Außenringkontakt 9 weist einen oder mehrere sich in axialer Richtung erstreckende Längsschlitze 18 auf, so daß die hierdurch gebildeten Teile des Außenringkontaktes 9 federnd nachgiebig sind und radial nach innen gedrückt werden können. Die Außenseite 19 des Außenringkontaktes 9 ist konisch ausgebildet und verjüngt sich nach vorne zur Kontaktseite hin. Das vordere Ende des Ringelementes 4 ist derart nach innen verjüngt ausgebildet, daß es sich von außen an die konische Außenseite 19 des Außenringkontaktes 9 anlegt. Wie aus Fig. 1 ersichtlich ist, werden die von den Längsschlitzen 18 gebildeten Teile des Außenringkontaktes 9 aufgrund der Konizität der Außenseite 19 radial nach innen gedrückt, wenn der Hülsenkörper 3 realtiv zum Steckerkörper 1 axial in Richtung auf die Kabelanschlußseite verschoben wird. Dabei wird das Ringelement 4 entsprechend in axialer Richtung auf die Außenseite 19 des Außenringkontaktes 9 gezogen, ohne sich selbst zu verdrehen. Die metallische Abdeckhülse 2, bestehend aus dem Hülsenkörper 3 und dem Ringelement 4, stellt einen metallischen Kontakt zwischen dem Außenringkontakt 9 und dem Anschluß 17 des Abschirmleiters 14 des angeschlossenen Koaxialkabels 15 her und schirmt den gesamten Innenraum des Steckers gegen Einfluß von außen ab.The outer ring contact 9 has one or more longitudinal slots 18 extending in the axial direction, so that the parts of the outer ring contact 9 formed thereby are resilient and can be pressed radially inwards. The outer side 19 of the outer ring contact 9 is conical and tapers towards the front towards the contact side. The front end the ring element 4 is tapered inwards in such a way that it lies against the conical outside 19 of the outer ring contact 9 from the outside. As can be seen from Fig. 1, the parts of the outer ring contact 9 formed by the longitudinal slots 18 are pressed radially inward due to the taper of the outer side 19 when the sleeve body 3 is actually displaced axially towards the plug body 1 in the direction of the cable connection side. The ring element 4 is drawn accordingly in the axial direction onto the outside 19 of the outer ring contact 9 without twisting itself. The metallic cover sleeve 2, consisting of the sleeve body 3 and the ring element 4, provides a metallic contact between the outer ring contact 9 and the terminal 17 of the shielding conductor 14 of the connected coaxial cable 15 and shields the entire interior of the plug against external influences.

Zum Aufstecken des Cinch (RCA)-Steckers auf eine entsprechend in der Zeichnung nicht dargestellte Buchse wird zunächst der Außenringkontakt 9 über das entsprechende Gegenstück der Anschlußbuchse geschoben, wobei zugleich der Kontaktstift 8 den vorgesehenen elektrischen Kontakt herstellt. Dann wird durch Verdrehen des Hülsenkörpers 3 der Außenringkontakt 9 durch das sich nicht mitdrehende Ringelement 4 radial zusammengedrückt, so daß der Außenringkontakt 9 sich an dem entsprechenden Gegenstück der Anschlußbuchse festklemmt.To plug the RCA (RCA) connector onto a socket (not shown in the drawing), the outer ring contact 9 is first pushed over the corresponding counterpart of the connection socket, the contact pin 8 simultaneously making the intended electrical contact. Then, by rotating the sleeve body 3, the outer ring contact 9 is radially compressed by the non-rotating ring element 4, so that the outer ring contact 9 is clamped to the corresponding counterpart of the connecting socket.

Bei der in der Zeichnung dargestellten Ausführungsform kann die Abdeckhülse 2, die sich aus dem Hülsenkörper 3 und dem Ringelement 4 zusammensetzt, außen mit einer isolierenden Beschichtung, beispielsweise einer isolierenden Eloxalschicht beschichtet sein. Diese Isolierung verhindert den elektrischen Kontakt zwischen den Abdeckhülsen 2 von dicht nebeneinander angeordneten Cinch (RCA)-Steckern gemäß der Erfindung.In the embodiment shown in the drawing, the cover sleeve 2, which is composed of the sleeve body 3 and the ring element 4, can be externally coated with an insulating coating, for example an insulating one Anodized layer can be coated. This insulation prevents electrical contact between the cover sleeves 2 of cinch (RCA) plugs arranged close to one another according to the invention.
