Description

Die Erfindung betrifft einen Steckverbinder für einen ringgewellten Außenleiter aufweisende Koaxialkabel, mit einem Steckerkopf, der eine Ausnehmung mit einer Ringfläche hat, durch die der in Höhe einer Erweiterung des Kabelaußenleiters von einem Wellental in Richtung auf einen Wellenscheitel liegenden Stirnrandbereich des Kabelaußenleiters innenseitig kontaktierbar ist, sowie mit einer gegen den Steckerkopf verspannbaren Kontakthülse, die den Kabelaußenleiter im montierten Zustand umschließt und die durch von ihrem steckseitigen Ende ausgehende, axiale Schlitze in radial federnde Segmente unterteilt ist, die an ihren freien Enden Verdickungen haben, die im montierten Zustand in dem ersten vollständigen Wellental des Kabelaußenleiters liegen und den über die Kontakthülse steckseitig überstehende Endbereich des Kabelaußenleiters gegen die Ringfläche in der Ausnehmung des Steckerkopfes klemmen, wobei die Ausnehmung einen Innendurchmesser mindestens gleich dem Außendurchmesser der Kontakthülse im Bereich der Verdickungen an den freien Enden der Segmente zuzüglich etwa der zweifachen Wellungshöhe des Kabelaußenleiters hat und wobei eine die Kontakthülse umschließende Hohlschraube im montierten Zustand nach dem Zurücklegen eines Spannweges durch Eindrehen in die Ausnehmung des Steckerkopfes die Verdickungen der Kontakthülse umgibt und in Spannrichtung belastet.The invention relates to a connector for a ring-corrugated Coaxial cables having outer conductors, with a Plug head, which has a recess with an annular surface, through which in the amount of an extension of the outer cable from a wave trough towards a wave crest lying front edge area of the cable outer conductor is contactable on the inside, as well as with one against the Plug head clampable contact sleeve, which the outer cable encloses in the assembled state and by by outgoing axial slots in its plug end radially resilient segments is divided at their free Ends have thickenings that when assembled in the first complete wave trough of the cable outer conductor lie and the protruding over the contact sleeve on the plug side End area of the cable outer conductor against the ring surface clamp in the recess of the plug head, the recess an inner diameter at least equal to the outer diameter the contact sleeve in the area of the thickened areas the free ends of the segments plus about twice Corrugation height of the outer cable has and where one Hollow screw enclosing the contact sleeve when assembled after covering a span by screwing in in the recess of the plug head the thickening of the Contact sleeve surrounds and loaded in the clamping direction.

Ein derartiger Steckverbinder ist aus der FR 2 682 819 A1 bekannt. Der bekannte Steckverbinder wird komplett vormontiert geliefert und kann nach dem Einführen des Koaxialkabels in die Ausnehmung des Steckerkopfes durch Eindrehen der Hohlschraube in die Ausnehmung auf dem Koaxialkabel befestigt werden. Die Vormontage ist insbesondere dann von Vorteil, wenn der Steckverbinder an exponierten Montageorten mit dem Koaxialkabel verbunden werden muß, da der Steckverbinder aufgrund der Vormontage mit Hilfe eines einfachen Schraubvorgangs mit dem Kabel verbunden werden kann. Außerdem braucht der bekannte Steckverbinder nicht wie andere herkömmliche Steckverbinder erst am Montageort zusammengesetzt werden. Es besteht also nicht die Gefahr, daß bei der Montage vor Ort Teile verloren gehen.Such a connector is from FR 2 682 819 A1 known. The known connector is completely pre-assembled supplied and can be inserted after inserting the coaxial cable by screwing into the recess of the plug head the banjo bolt into the recess on the coaxial cable be attached. The pre-assembly is especially of Advantage if the connector is in exposed installation locations must be connected to the coaxial cable, since the Connector due to pre-assembly using a simple Screwing process can be connected to the cable. In addition, the known connector does not need like others conventional connectors are only assembled at the installation site become. So there is no danger that Parts are lost during assembly on site.

Allerdings ist es gelegentlich erforderlich, einen vormontierten Stecker am Montageort zu zerlegen und erneut zusammenzubauen. Bei dem bekannten Steckverbinder kann dies zu Schwierigkeiten führen. Insbesondere beim Zusammenbau kann es vorkommen, daß der Steckverbinder nicht mehr in den werksseitig definierten vormontierten Zustand gebracht wird, so daß es bei der Montage auf das Kabel zu Schwierigkeiten kommt.However, it is sometimes necessary to have a pre-assembled one Disassemble the connector at the installation site and reassemble it. In the known connector this can be done Cause difficulties. Especially when assembling it happens that the connector is no longer in the brought pre-assembled state defined in the factory becomes so that it is difficult to assemble on the cable comes.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der einleitend angegebenen Gattung zu schaffen, der sich einfach, schnell und zuverlässig montieren läßt.The invention has for its object a connector to create the genus specified in the introduction, the can be installed easily, quickly and reliably.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß der Steckverbinder eine Einrichtung aufweist, die den Spannweg der Hohlschraube in zwei Abschnitte gliedert, von denen der erste einem vormontierten Zustand des Verbinders und das Ende des zweiten Abschnitts (L) des Endmontage des Verbinders auf dem Kabelende entspricht.This object is achieved in that the Connector has a device that the span the banjo bolt is divided into two sections, of which the first a pre-assembled state of the connector and the end of the second section (L) of final assembly of the connector on the cable end.

Der Monteur kann dann den vormontierten Steckverbinder, falls aus irgendwelchen Gründen notwendig, vor der Montage auf dem Kabel zerlegen und anschließend wieder in den vormontierten Zustand bringen. Dabei gelangt er stets wieder in den vormontierten Zustand. The fitter can then use the pre-assembled connector, if necessary for any reason, before assembly Disassemble on the cable and then back into the pre-assembled Bring condition. He always comes back in the pre-assembled state.

Im weiteren Verlauf der Montage braucht der Steckverbinder lediglich auf das wie üblich vorbereitete Kabelende bis zum Anschlag aufgeschoben werden. Sodann braucht der Monteur nur noch die Hohlschraube in den Steckerkopf einzudrehen, bis ein vorgeschriebenes Anzugsdrehmoment erreicht ist, das anzeigt, daß die gewünschte Klemmung des Außenleiters eingetreten ist. Das einzige gegebenenfalls getrennt zu handhabende Teil ist damit der wie bei dem Steckverbinder nach dem Stand der Technik als erstes auf den Kabelaußenleiter aufzuziehende O-Ring. Auch auf diesen kann jedoch verzichtet werden, wenn zur Abdichtung ein flüssiger, z.B. über eine Radialbohrung in der Hohlschraube eingespritzter Dichtungswerkstoff verwendet wird oder die Abdichtung zwischen dem Steckverbinder und dem Kabel mittels eines Schrumpfschlauches vorgenommen wird. Wenn während des Eindrehens der Hohlschraube der Steckerkopf festgehalten wird, hat der vorgeschlagene Steckverbinder gegenüber demjenigen nach dem Stand der Technik den weiteren Vorteil, daß die kontaktierenden Flächen nicht gegeneinander verdreht werden, weil die Hohlschraube die Kontakthülse nur in axialer Richtung verschiebt.In the further course of the assembly the connector needs only on the cable end prepared as usual up to Stop being pushed on. Then the fitter needs just screw the banjo bolt into the plug head, until a prescribed tightening torque is reached, which indicates that the desired clamping of the outer conductor has occurred is. The only one that can be handled separately if necessary Part is the same as for the connector state of the art first on the cable outer conductor O-ring to be fitted. However, this can also be dispensed with if a liquid, e.g. about a radial hole in the hollow screw injected sealing material is used or the seal between the connector and the cable using a shrink tube is made. If during screwing in the banjo bolt of the plug head is held proposed connector compared to that after State of the art has the further advantage that the contacting Surfaces cannot be twisted against each other because the banjo bolt only in the axial direction shifts.

Um sicherzustellen, daß die Kontakthülse bei der Montage des Steckverbinders auf dem Kabel ihre korrekte Stellung einnimmt, ist es zweckmäßig, wenn an den Verdickungen an den freien Enden der Segmente der Kontakthülse jeweils eine auf einer Kegelmantelfläche liegende Auflauffläche für den Stirnrand des Kabelaußenleiters ausgebildet und der Kegelwinkel so gewählt ist, daß die Segmente bei Überschreitung einer gewissen, von dem Stirnrand des Kabelaußenleiters auf die Auflaufflächen ausgeübten Axialkraft radial auffedern (Anspruch 2). Hierdurch wird erreicht, daß der Stirnrand des Kabelaußenleiters beim Aufschieben des Steckverbinders auf das Kabelende die Kontakthülse in eine definierte Stellung schiebt, in der sich die Verdickungen an den freien Enden der Segemente der Kontakthülse im wesentlichen in Höhe der Ringfläche in der Ausnehmung des Steckerkopfes befinden. Die definierte Stellung kann insbesondere durch einen den axialen Verschiebeweg der Kontakthülse begrenzenden Anschlag bestimmt sein. Z.B. kann die Kontakthülse an ihrem kabelseitigen Ende einen Umfangsbereich mit vergrößertem Außendurchmesser haben, der in der vormontierten Stellung mit einem steckseitig davon liegenden Innenbund in der Hohlschraube zusammenwirkt.To ensure that the contact sleeve during assembly the correct position of the connector on the cable takes, it is useful if the thickening the free ends of the segments of the contact sleeve one each on a conical outer surface for the Front edge of the cable outer conductor and the cone angle is selected so that the segments are exceeded a certain amount, from the front edge of the cable outer conductor radially spring up the thrust surfaces (Claim 2). This ensures that the front edge the outer cable when pushing on the connector on the cable end the contact sleeve in a defined position in which the thickenings on the free Ends of the segments of the contact sleeve essentially in Height of the ring surface in the recess of the plug head are located. The defined position can in particular by a limiting the axial displacement of the contact sleeve Be determined. For example, can the contact sleeve its cable-side end a circumferential area with an enlarged Have outside diameter, that in the pre-assembled Position with an inner collar in the the banjo bolt interacts.

Die den Vormontagezustand kennzeichnende Einrichtung kann aus einer Markierung der Stellung der Hohlschraube am Ende des ersten Abschnitts bestehen (Anspruch 3). The device characterizing the pre-assembly state can from a marking of the position of the banjo bolt at the end of the first section (claim 3).

Die Einrichtung kann auch so ausgebildet sein, daß sich das zum Eindrehen der Hohlschraube in der Ausnehmung des Steckverbinderkopfs erforderliche Drehmoment am Ende des ersten Abschnittes fühlbar erhöht (Anspruch 4).The device can also be designed so that the for screwing in the banjo bolt in the recess of the connector head required torque at the end of the first Section noticeably increased (claim 4).

Insbesondere kann die Einrichtung aus einem zwischen dem Steckerkopf und der Hohlschraube am Ende des ersten Abschnitts angeordneten O-Ring oder dergl. bestehen (Anspruch 5).In particular, the device from one between the Connector head and banjo bolt at the end of the first section arranged O-ring or the like. (Claim 5).

Zusätzlich oder alternativ kann die Einrichtung aus einer am Ende des ersten Spannwegabschnittes befindlichen Materialverformung zwischen den relativ zueinander verschiebbaren Teilen bestehen (Anspruch 6).Additionally or alternatively, the device can be made from an am Material deformation located at the end of the first span section between those that are slidable relative to each other Share exist (claim 6).

Zweckmäßig ist die Kontakthülse unverlierbar in der Hohlschraube gehalten (Anspruch 7). Hierzu können z.B. der größte Außendurchmesser der Kontakthülse in Höhe der Verdickungen an den freien Enden der Segmente und die Breite der Schlitze zwischen den Segmenten so aufeinander abgestimmt sein, daß sich die Verdickungen radial ausreichend weit zusammendrücken lassen, um die Kontakthülse in die Hohlschraube von deren kabelseitigen Ende her einführen zu können und die Verdickungen unter dem oben erwähnten Innenbund der Hohlschraube hindurchgleiten zu lassen.The contact sleeve is expediently captive in the banjo bolt kept (claim 7). For this, e.g. the largest outer diameter of the contact sleeve in the amount of the thickening at the free ends of the segments and the width the slots between the segments matched to each other be that the thickenings are sufficient radially allow to squeeze far enough to insert the contact sleeve into the Insert the banjo bolt from the cable end can and the thickening under the inner waistband mentioned above to let the banjo bolt slide through.

Zur Übertragung des Axialschubes der Hohlschraube auf die Kontakthülse können die Verdickungen an den freien Enden der Segmente der Kontakthülse kabelseitig eine Ringschulter haben, die mit einem Innenbund der Hohlschraube zusammenwirkt (Anspruch 8). To transmit the axial thrust of the banjo bolt to the The thickening at the free ends of the contact sleeve Segments of the contact sleeve have an annular shoulder on the cable side, which cooperates with an inner collar of the banjo bolt (Claim 8).

Der in Figur 1 im Vormontagezustand, also so, wie er vom Hersteller ausgeliefert wird, dargestellte Steckverbinder umfaßt einen Steckerkopf 5 in dem ein Steckerinnenleiter 60 über eine Isolierstoffscheibe 70 gehalten ist. Der Steckerkopf 5 trägt einen nicht näher bezeichneten Schraubüberwurf. An seinem kabelseitigen Ende hat der Steckerkopf 5 eine Ausnehmung 51, die von einer Kegelringfläche 52 begrenzt wird. In der Ausnehmung 51 befindet sich eine Kontakthülse 6, die durch von ihrem steckseitigen Ende ausgehende, axiale Schlitze 61 in federnde Segmente 62 unterteilt ist, die an ihren freien Enden Verdickungen 63 haben. Die Kontakthülse 6 ist in dem dargestellten Vormontagezustand in einer Hohlschraube 7 frei verschiebbar, deren Außengewinde in ein Innengewinde in der Wand der Ausnehmung 51 des Steckerkopfs eingreift. Die Hohlschraube 7 trägt einen O-Ring 8, der bei in den Steckerkopf eingedrehter Hohlschraube die Abdichtung der Ausnehmung 51 sicherstellt. Außerdem kann zu dem Steckverbinder ein Dichtring 9 gehören.The in Figure 1 in the pre-assembled state, so as it from Manufacturer shipped, illustrated connectors comprises a plug head 5 in which a plug inner conductor 60 is held over an insulating disk 70. The plug head 5 carries a screw cap, not specified. At its cable end, the plug head 5 has one Recess 51, which is bounded by a conical ring surface 52 becomes. A contact sleeve is located in the recess 51 6, the axial from its mating end Slits 61 is divided into resilient segments 62 that are attached to their free ends have thickenings 63. The contact sleeve 6 is in the pre-assembled state in a banjo bolt 7 freely movable, the external thread in one Internal thread in the wall of the recess 51 of the plug head intervenes. The banjo bolt 7 carries an O-ring 8 which the sealing screw screwed into the plug head the recess 51 ensures. In addition to that Connectors include a sealing ring 9.

Gemäß den Figuren 2 und 3 sitzt der Steckverbinder auf dem passend hergerichteten Ende eines Koaxialkabels, hat aber noch nicht seine endgültige Stellung erreicht. Das Koaxialkabel umfaßt wie üblich einen Innenleiter 1, ein Kabeldielektrikum 2, einen ringgewellten Außenleiter 3 und einen Kabelmantel 4. Zuvor wurde der Dichtring 9 auf den Kabelaußenleiter 3 so weit aufgezogen, daß er in das erste freie Wellental im Anschluß an den Kabelmantel 4 zu liegen kommt. Der Dichtring 9 dichtet den Spalt zwischen dem Kabelaußenleiter 3 und der Innenfläche der Hohlschraube 7 ab. Das gleiche läßt sich auch auf andere Weise, z.B. durch nachträgliches Einspritzen eines elastischen Dichtungsmittels in den Ringspalt und/oder den Raum, den vorliegend der Dichtring 9 einnimmt, erreichen.According to Figures 2 and 3, the connector sits on the suitably prepared end of a coaxial cable, but has has not yet reached its final position. The coaxial cable comprises, as usual, an inner conductor 1, a cable dielectric 2, a ring-corrugated outer conductor 3 and one Cable sheath 4. Previously, the sealing ring 9 was on the outer cable 3 raised so far that he is in the first free Wave trough comes to rest after the cable sheath 4. The sealing ring 9 seals the gap between the cable outer conductor 3 and the inner surface of the banjo bolt 7. The The same can also be done in other ways, e.g. through subsequent Inject an elastic sealant into the annular gap and / or the space, in the present case the sealing ring 9 takes, reach.

In der in den Fig. 1 und 2 dargestellten Stellung ist die Hohlschraube 7 nur etwa bis zur Hälfte der Länge ihres Außengewindes in den Steckerkopf 5 eingedreht. Diese Stellung der Hohlschraube 7 relativ zu dem Steckerkopf 5 ist durch eine Markierung in Form einer flachen Ringnut 71 definiert. In der Ringnut 71 könnte sich ein kleiner O-Ring befinden, so daß sich das zum weiteren Eindrehen der Hohlschraube 7 in den Steckerkopf 5 erforderliche Drehmoment etwas erhöhen würde. Die Markierung 71 gliedert also die Eindrehlänge der Hohlschraube 7 in zwei Abschnitte. Die Länge des zweiten Abschnittes ist mit L bezeichnet. Die Markierung kann statt aus der gezeichneten Ringnut auch aus einem Farbring, einer kleiner Materialverformung entweder am Steckerkopf oder an der Hohlschraube sowie aus jeder anderen Einrichtung bestehen, die an beliebiger Stelle zwischen dem Steckerkopf 5 und der Hohlschraube 7 dafür sorgt, daß der gezeichnete Vormontage- zustand des Steckverbinders hergestellt und eingehalten wird.In the position shown in FIGS. 1 and 2, the Banjo bolt 7 only up to about half the length of their External thread screwed into the plug head 5. This position the hollow screw 7 is relative to the plug head 5 by a mark in the form of a flat annular groove 71 Are defined. A small O-ring could be in the ring groove 71 are so that it is for further screwing in the banjo bolt 7 required torque in the plug head 5 would raise something. The marker 71 thus divides the Screw-in length of banjo bolt 7 in two sections. The The length of the second section is designated by L. The Marking can also be made from the drawn ring groove a color ring, a small material deformation either on Plug head or on the banjo bolt as well as from any other Establishment that exist anywhere between the Plug head 5 and the hollow screw 7 ensures that the shown pre-assembled state of the connector and is observed.

Im Vormontagezustand ist die Kontakthülse 6 zunächst in der Hohlschraube 7 frei verschiebbar (vgl. Fig. 1), wird jedoch nach dem Aufsetzen des Steckverbinders auf das Kabelende (Fig. 2) zwangsläufig in die gezeichnete Stellung gebracht. Wie die Figuren 2 und 3 verdeutlichen, liegt nämlich der Stirnrand 31 des Kabelaußenleiters 3 in Höhe einer Erweiterung des letzteren von einem Wellental in Richtung auf einen Wellenscheitel und läuft zunächst gegen eine Auflauffläche 63a an der Innenseite der Verdickungen 63 an den Enden der Segmente 62 der Kontakthülse 6. Diese Auflauffläche 63a ist Teil einer umlaufenden Kegelfläche, die gleichzeitig das einspringende Profil der Verdickungen begrenzt, das in etwa an das Wellungsprofil des Kabelaußenleiters 3 angepaßt ist. Wenn sich also beim Aufsetzen des Steckverbinders auf das Kabelende die Kontakthülse 6 zunächst in irgendeiner anderen als der gezeichneten Stellung befindet, sorgt der Stirnrand 31 des Kabelaußenleiters in Verbindung mit der Auflauffläche 63a dafür, daß die Kontakthülse 6 mitgenommen wird, bis sie die gezeichnete Stellung erreicht hat. Fig. 3 zeigt weiter, daß jede der Verdickungen 63 innenseitig eine zu der Auflauffläche 63a gegenläufige Kegelfläche 63b hat, die im wesentlichen parallel zu der Ringfläche 52 des Steckerkopfes verläuft. Außenseitig ist jede Verdickung 63 von einer Zylindersegmentfläche 63c begrenzt, an die sich eine in einer Radialebene Ringschulter 63d anschließt. Die beiden letztgenannten Flächen sind zum Zusammenwirken mit dem sich an einen Innenbund 72 der Hohlschraube 7 anschließenden, rohrförmigen Vorderende 73 bestimmt, wie unten erläutert werden wird.In the pre-assembled state, the contact sleeve 6 is initially in the Banjo bolt 7 can be moved freely (see FIG. 1), however after placing the connector on the cable end (Fig. 2) inevitably brought into the position shown. As shown in FIGS. 2 and 3, the Front edge 31 of the outer cable 3 at the level of an extension the latter from a trough towards one Wave apex and initially runs against a run-up surface 63a on the inside of the thickenings 63 at the ends of the Segments 62 of the contact sleeve 6. This ramp surface 63a is Part of a circumferential conical surface, which at the same time the re-entrant profile of the thickenings limited, that roughly is adapted to the corrugation profile of the cable outer conductor 3. So if when fitting the connector on the Cable end, the contact sleeve 6 first in any other than the drawn position, the forehead edge provides 31 of the cable outer conductor in connection with the contact surface 63a for the contact sleeve 6 being taken along until it has reached the position shown. 3 further shows that each of the thickenings 63 inside one to the ramp surface 63a has opposite conical surface 63b, which in substantially parallel to the annular surface 52 of the plug head runs. On the outside, each thickening 63 is one Cylinder segment surface 63c bounded by an in connects a radial plane annular shoulder 63d. The two the latter areas are to interact with yourself adjoining an inner collar 72 of the hollow screw 7, tubular front end 73 determines, as explained below will be.

Beim weiteren Aufschieben des Steckverbinders auf das Kabelende federn, wie in Fig. 4 gezeigt, die Segmente 62 in radialer Richtung auseinander, so daß der Steckverbinder nun bis zum Anschlag aufgedrückt werden kann. Hierzu hat die Ausnehmung 51 einen ausreichend groß bemessenen Innendurchmesser. Anschließend federn die Segmente 62 wieder zusammen, so daß nun die Verdickungen 63 an deren freien Enden in das erste vollständige Wellental des Kabelaußenleiter 3 eingreifen. Gleichzeitig liegt der an den Stirnrand 31 des Kabelaußenleiters 3 anschließende Bereich auf der Ringfläche 52 auf und wird von dieser innenseitig kontaktiert (vgl. Fig 5). Dann wird die Hohlschraube 7 in den festgehaltenen Stekkerkopf 5 eingedreht, bis sie sich in der in Fig. 5 gezeigten Stellung befindet. Währenddessen verhindert das rohrförmige Vorderende 73 der Hohlschraube 7 ein radiales Ausweichen der Segemente 62 der Kontakthülse 6, denn der Innendurchmesser des rohrförmigen Vorderendes 73 ist nur geringfügig größer als der Außendurchmesser der Kontakthülse in Höhe der Flächen 63c (vgl. Fig. 3) der Verdickungen 63. Sobald deshalb die einspringende Ringfläche des Innenbundes 72 der Hohlschraube 7 zur Anlage an die Ringschultern 63d der Verdickungen 63 kommt, wird die Kontakthülse 7 in axialer Richtung auf die Ringfläche 52 aufgeschoben. Das Eindrehen der Hohlschraube 7 wird dann fortgesetzt, bis ein vorgeschriebenes Anzugsdrehmoment erreicht ist, das eine sichere Kontaktierung und Klemmung des zwischen die Kegelringfläche 52 und die etwa gleichlaufende Fläche 63b eingespannten Bereichs des Kabelaußenleiters 3 anzeigt.When pushing the connector further onto the cable end 4, segments 62 in radial direction apart, so that the connector is now can be pushed on as far as it will go. For this, the Recess 51 has a sufficiently large inner diameter. Then the segments 62 spring back together, so that the thickenings 63 at their free ends in the engage the first complete wave trough of the outer cable 3. At the same time lies on the front edge 31 of the Cable outer conductor 3 adjoining area on the ring surface 52 and is contacted by the inside (see FIG 5). Then the banjo bolt 7 is held in the connector head 5 screwed in until it is shown in FIG Position. Meanwhile, the tubular prevents Front end 73 of the hollow screw 7 a radial evasion the segments 62 of the contact sleeve 6, because the inner diameter the tubular front end 73 is only slight larger than the outer diameter of the contact sleeve in Height of the surfaces 63c (see FIG. 3) of the thickenings 63. As soon as the ring surface of the inner collar is inserted 72 of the hollow screw 7 to rest against the ring shoulders 63d the thickening 63 comes, the contact sleeve 7 in the axial Pushed onto the ring surface 52. The screwing in the banjo bolt 7 is then continued until a specified tightening torque is reached, the one Secure contacting and clamping between the conical ring surface 52 and the approximately co-rotating surface 63b Area of the outer cable 3 displays.
