This in turn leads to a considerable saving in material and production time and to a time savings in the assembly of the connector on the cable, because the number of rotations of the hollow screw until reaching the clamping state is approximately halved.

Description

Die Erfindung betrifft einen Steckverbinder mit einem Stekkerkopf und einer in diesen eindrehbaren Hohlschraube.The invention relates to a connector with a Stekkerkopf and a screwed into this hollow screw.

Ein derartiger Steckverbinder ist in der nichtvorveröffentlichten deutschen Patentanmeldung 197 38 733.0 beschrieben. Dieser Steckverbinder braucht im Gegensatz zu Steckverbindern nach dem Stand der Technik, z.B. nach der DE-C-27 24 862 , vor der Montage auf dem Kabel nicht zerlegt zu werden. Vielmehr kann der Steckverbinder so vormontiert ausgeliefert werden, daß er lediglich auf das wie üblich vorbereitete Kabelende bis zum Anschlag aufgeschoben werden muß. Sodann braucht der Monteur nur noch die Hohlschraube in den Stekkerkopf einzudrehen, bis ein vorgeschriebenes Anzugsdrehmoment erreicht ist, das anzeigt, daß die gewünschte Klemmung des Kabelaußenleiters eingetreten ist. Gewünschtenfalls kann der Monteur den Steckverbinder auch durch vollständiges Herausdrehen der Hohlschraube aus dem Steckerkopf zerlegen. Der Weg, den die Hohlschraube dann beim Eindrehen in die Aufnehmung des Steckerkopfes bis zur Klemmung des Kabelaußenleiters zurücklegen muß, ist der Spannweg. Dieser hat zwei Abschnitte, von denen der erste dem vormontierten Zustand des Steckverbinders und der zweite dessen Endmontage auf dem Kabel entspricht. Da es für eine ordnungsgemäße Montage wichtig ist, daß sich der Steckverbinder beim Aufschieben auf das Kabelende in seinem werksseitig festgelegten Vormontagezustand befindet, hat er eine Einrichtung, die das Ende des ersten und damit den Beginn des zweiten Abschnittes des Spannweges erkennen läßt. In der vorgenannten, älteren deutschen Patentanmeldung wird hierfür eine das Gewinde der Hohlschraube in zwei etwa gleichlange Abschnitte teilende Ringnut vorgeschlagen, in der ein zweiter, dünner O-Ring angeordnet ist. Zwischen dem Ende des Gewindes der Hohlschraube und deren Schraubenkopf befindet sich eine weitere Ringnut, in welcher der erste O-Ring angeordnet ist, der im montierten Zustand des Steckverbinders den Ringspalt zwischen dem Steckerkopf und der Hohlschraube abdichtet. Wegen der Teilung des Gewindes der Hohlschraube in zwei Abschnitte ist ein relativ langes Gewinde erforderlich. Entsprechend lang bauen die Hohlschraube, der Steckerkopf und damit auch der Steckverbinder insgesamt.Such a connector is in the non-prepublished German patent application 197 38 733.0 described. This connector needs, in contrast to connectors according to the prior art, for example after the DE-C-27 24 862 not to be disassembled before mounting on the cable. Rather, the connector can be delivered pre-assembled so that it must be pushed only to the usual prepared cable end to the stop. Then the installer only needs to screw the hollow screw in the Stekkerkopf until a prescribed tightening torque is reached, indicating that the desired clamping of the cable outer conductor has occurred. If desired, the installer can disassemble the connector by completely unscrewing the banjo bolt from the plug head. The path that the hollow screw then has to travel when screwing into the Aufnehmung of the plug head to the clamping of the cable outer conductor, is the clamping path. This has two sections, the first of which corresponds to the preassembled state of the connector and the second whose final assembly on the cable. Since it is important for proper mounting that the connector is in its factory pre-assembled state when pushed onto the cable end, it has a device that can detect the end of the first and thus the beginning of the second section of the clamping path. In the aforementioned, older German patent application for this purpose, a thread of the hollow screw in two approximately equal sections dividing annular groove is proposed, in which a second, thin O-ring is arranged. Between the end of the thread of the hollow screw and the screw head there is a further annular groove, in which the first O-ring is arranged, which seals the annular gap between the plug head and the hollow screw in the assembled state of the connector. Because of the division of the thread of the hollow screw in two sections a relatively long thread is required. Correspondingly long build the hollow screw, the plug head and thus the connector as a whole.

FR 2 682 819 offenbart einen Steckverbinder mit einem Steckerkopf, einer Hohlschraube und einer Kontakthülse, der für eine ringgewelltes Koaxialkabel ausgestaltet ist. Dieser Steckverbinder muss für die Montage zerlegt werden. Ein O-Ring ist zur Abdichtung zwischen der Hohlschraube und dem Steckerkopf vorgesehen. FR 2 682 819 discloses a connector with a plug head, a banjo bolt and a contact sleeve, which is designed for a ring-waved coaxial cable. This connector must be disassembled for assembly. An O-ring is provided for sealing between the banjo bolt and the plug head.

Der Erfindung liegt die Aufgabe zugrunde, die axiale Länge des Steckverbinders der einleitend angegebenen Gattung zu verringern.The invention has for its object to reduce the axial length of the connector of the introductory genus specified.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß bei dem Steckverbinder mit den im Anspruch 1 angegebenen Merkmalen die Einrichtung, die den Spannweg der Hohlschraube in zwei Abschnitte gliedert, aus dem abdichtenden O-Ring besteht, der so angeordnet ist, daß er am Ende des ersten Spannwegabschnittes auf den kabelseitigen Stirnrand des Steckerkopfes aufläuft und daß die Ausnehmung (51) des Steckerkopfes (5) kabelseitig einen innengewindelosen Abschnitt mit einem Innendurchmesser hat, der größer als der Außendurchmesser der Hohlschraube (7) im Bereich ihres Gewindes (72) ist.This object is achieved in that in the connector with the features specified in claim 1, the device which divides the clamping path of the hollow screw into two sections, consists of the sealing O-ring, which is arranged so that it at the end of the first Spannwegabschnittes runs on the cable-side end edge of the plug head and that the recess (51) of the plug head (5) cable side has a innenwindindelosen section with an inner diameter which is greater than the outer diameter of the hollow screw (7) in the region of its thread (72).

Der Kern der Erfindung besteht also darin, auf den zweiten, dünnen O-Ring zu verzichten und stattdessen den ohnehin vorhandenen, ersten O-Ring nicht nur zur Abdichtung zwischen Hohlschraube und Steckerkopf sondern auch als Mittel zur Markierung des korrekten Vormontagezustandes zu verwenden. Diese auf den ersten Blick einfach erscheinende Konstruktion des Steckverbinders hat eine ganze Reihe von Vorteilen, die im wesentlichen daraus resultieren, daß sich die erforderliche Gewindelänge der Hohlschraube im Vergleich zu der einleitend beschriebenen Konstruktion auf etwa die Hälfte vermindert. Damit verringert sich die Baulänge der Hohlschraube, dementsprechend diejenige des Steckerkopfes und im Ergebnis die Baulänge des Steckverbinders insgesamt. Dies wiederum führt zu einer beträchtlichen Einsparung an Material und Fertigungszeit und zu einer Zeitersparnis bei der Montage des Steckverbinders auf dem Kabel, weil die Zahl der Drehungen der Hohlschraube bis zum Erreichen des Klemmzustandes sich etwa halbiert.The essence of the invention is therefore to dispense with the second, thin O-ring and instead to use the already existing, first O-ring not only for sealing between hollow screw and plug head but also as a means for marking the correct pre-assembly state. This seemingly simple design of the connector has a number of advantages, which essentially result from the fact that the required thread length of the hollow screw decreases in comparison to the construction described in the introduction to about half. This reduces the overall length of the hollow screw, accordingly that of the plug head and as a result the overall length of the connector as a whole. This in turn leads to a considerable saving in material and production time and to a time savings in the assembly of the connector on the cable, because the number of rotations of the hollow screw until reaching the clamping state is approximately halved.

Die Erfindung betrifft des weiteren einen Steckverbinder mit einem Steckerkopf und einer auf diesen aufdrehbaren Überwurfhülse. Ein derartiger Steckverbinder ist in den Fig. 9 und 10 der nichtvorveröffentlichten deutschen Patentanmeldung 198 46 440.1 dargestellt. Er bietet die gleichen montagetechnischen Vorteile wie der in der eingangs genannten deutschen Patentanmeldung 197 38 733.0 beschriebene Steckverbinder, umfaßt jedoch nur einen einzigen O-Ring zur Abdichtung des Ringspaltes zwischen dem Steckerkopf und der Überwurfhülse, weil die Gliederung des Spannweges in zwei Abschnitte durch das Zusammenwirken eines das Innengewinde der Überwurfhülse unterbrechenden, gewindelosen Abschnittes und eines höchstens die gleiche Länge wie dieser gewindelose Abschnitt aufweisenden Außengewindeabschnitts des Steckerkopfes realisiert ist. Auch dieser Steckverbinder baut deshalb vergleichsweise lang.The invention further relates to a connector with a plug head and a aufdrehbaren on this cap sleeve. Such a connector is shown in Figs. 9 and 10 of the unpublished German patent application 198 46 440.1 shown. It offers the same mounting advantages as the German patent application mentioned above 197 38 733.0 described connector, but includes only a single O-ring for sealing the annular gap between the plug head and the cap sleeve, because the outline of the clamping path in two sections by the interaction of the internal thread of the cap sleeve interrupting, non-threaded portion and a maximum of the same length as this threaded section having male threaded portion of the plug head is realized. This connector therefore also builds comparatively long.

Zur Lösung der gleichen Aufgabe wie im Fall des einen Stekkerkopf mit eingedrehter Hohlschraube umfassenden Steckverbinders wird bei dem Steckverbinder mit den im Anspruch 2 angegebenen Merkmalen erfindungsgemäß vorgeschlagen, daß die Einrichtung, die den Spannweg der Überwurfhülse in zwei Abschnitte gliedert, aus dem abdichtenden O-Ring besteht, auf den der steckseitige Stirnrand der Überwurfhülse am Ende des ersten Spannwegabschnittes aufläuft.To solve the same problem as in the case of a Stekkerkopf with screwed hollow screw comprehensive connector according to the invention proposed in the connector with the features specified in claim 2, that the device, which divides the tension of the cap sleeve in two sections, from the sealing O-ring exists, on which the plug-side end edge of the cap sleeve runs up at the end of the first Spannwegabschnittes.

Die mit dieser Lösung erzielten Vorteile sind im wesentlichen die gleichen wie vorstehend für die erste Lösung angegeben.The advantages achieved with this solution are essentially the same as stated above for the first solution.

Zur Erleichterung des Montagevorganges hat die Bohrung der Hohlschraube bzw. die Überwurfhülse innenseitig eine radial einspringende Schulter, die einen Anschlag für einen Ringbund der Kontakthülse bildet und im vormontierten Zustand des Steckverbinders den Verschiebeweg der Kontakthülse so begrenzt, daß zwischen der Ringfläche bzw. der Kegelringfläche und den Segmenten der Kontakthülse ein Einführspalt für den Endbereich des Kabelaußenleiters verbleibt (Anspruch 3). Bei den in den beiden genannten deutschen Patentanmeldungen beschriebenen Steckverbinderkonstruktionen konnte es hingegen vorkommen, daß der Stirnrand des Kabelaußenleiters im Zuge des Aufsetzens des vormontierten Steckverbinders auf das Kabel die Kontakthülse bis zur Auflage auf der kontaktierenden Ringfläche oder dem Boden des Steckerkopfes vorschob, in welchem Fall der Steckverbinder wieder abgezogen und von neuem auf das Kabel aufgesetzt werden mußte.To facilitate the assembly process, the bore of the hollow screw and the cap sleeve on the inside has a radially recessed shoulder, which forms a stop for a collar of the contact sleeve and in the preassembled state of the connector, the displacement of the contact sleeve so limited that between the annular surface or the cone ring surface and the segments of the contact sleeve an insertion gap for the end of the cable outer conductor remains (claim 3). In the connector constructions described in the two mentioned German patent applications, it could happen, however, that the front edge of the cable outer conductor in the course of placement of the preassembled connector on the cable, the contact sleeve to the support on the contacting ring surface or the bottom of the plug head advances, in which case Removed connector and again had to be placed on the cable.

Der den Verschiebeweg der Kontakthülse während des Aufsetzens des Steckverbinders auf das Kabel begrenzende Ringbund kann, bezogen auf die axiale Länge der Kontakthülse, so angebracht werden, daß die ohnehin vorhandene, einspringende Schulter der Hohlschraube bzw. der Überwurfhülse die Anschlagfunktion erfüllt, also kein gesonderter Bearbeitungsschritt der Hohlschraube bzw. der Überwurfhülse zur Erzeugung einer weiteren Schulter notwendig ist. In diesem Fall ist die einspringende Schulter der Hohlschraube bzw. der Überwurfhülse eine Ringschulter, deren steckseitige Stirnfläche am Ende des zweiten Spannwegabschnittes die Spannkraft auf an den steckseitigen Enden der Segmente der Kontakthülse ausgebildete Gegenflächen überträgt (Anspruch 4).The displacement of the contact sleeve during the placement of the connector on the cable limiting collar can, based on the axial length of the contact sleeve, are mounted so that the already existing, reentrant shoulder of the hollow screw or the cap sleeve fulfills the stop function, so no separate processing step the hollow screw or the cap sleeve to produce a further shoulder is necessary. In this case, the re-entrant shoulder of the hollow screw and the cap sleeve is an annular shoulder whose plug-side end face at the end of the second Spannwegabschnittes the clamping force on formed on the plug-side ends of the segments of the contact sleeve mating surfaces transfers (claim 4).

In den Fig. 1 bis 3 ist nur der hier interessierende, kabelseitige Teil der ersten Ausführungsform des Steckverbinders dargestellt. Fig. 4 zeigt den vollständigen Steckverbinder, wobei der steckseitige Teil des Steckerkopfes nur ein beliebiges, hier nicht näher interessierendes Ausführungsbeispiel ist. Im übrigen ist der dargestellte Steckverbinder mit Ausnahme der mit der Erfindung vorgeschlagenen Verbesserungen weitgehend identisch mit dem in der deutschen Patentanmeldung 197 38 733.0 dargestellten und erläuterten Steckverbinder.In the Fig. 1 to 3 only the interest here, cable-side part of the first embodiment of the connector is shown. Fig. 4 shows the complete connector, the plug-side part of the plug head is only an arbitrary, not interesting here embodiment. Moreover, the connector shown with the exception of the improvements proposed by the invention is largely identical to that in the German patent application 197 38 733.0 illustrated and explained connectors.

Fig. 1 zeigt den Steckerkopf 5 mit einem über eine nicht dargestellte Kunststoffscheibe gehaltenen Steckerinnenleiter 4. Der Steckerkopf 5 hat an seinem kabelseitigen Ende eine Ausnehmung 51, die an einer Kegelringfläche 52 endet und mit einem Innengewinde 53 versehen ist. Die Ausnehmung 51 ist zur Aufnahme einer Kontakthülse 6 bestimmt, die nach Art einer Spannzange ausgebildet und hierzu durch von ihrem steckseitigen Ende ausgehende, axiale Schlitze 61 in federnde Segmente 62 unterteilt ist, die an ihren freien Ende Verdickungen 63 haben. An ihrem gegenüberliegenden, kabelseitigen Ende 64 hat die Kontakthülse 6 einen etwas größeren Außendurchmesser als im Bereich ihrer federnden Segmente 62. In Höhe der federden Segmente 62 hat die Kontakthülse 6 einen (durch die Schlitze 61 unterbrochenen) Ringbund 65, vgl. Einzelheit "X". Fig. 1 shows the plug head 5 with a held on a plastic disk, not shown plug inner conductor 4. The plug head 5 has at its cable end a recess 51 which terminates at a conical annular surface 52 and is provided with an internal thread 53. The recess 51 is intended to receive a contact sleeve 6, which is designed in the manner of a collet chuck and which is divided from its plug-side end outgoing, axial slots 61 into resilient segments 62, which have thickenings 63 at their free end. At its opposite, cable-side end 64, the contact sleeve 6 has a slightly larger outer diameter than in the region of its resilient segments 62. In the amount of federden segments 62, the contact sleeve 6 has a (interrupted by the slots 61) annular collar 65, see. Detail "X".

Die Kontakthülse 6 ist unter Zusammendrücken der federnden Segmente 62 in eine Hohlschraube 7 von deren kabelseitigem Ende her eingesetzt. Die Hohlschraube 7 hat nahe ihrem steckseitigen Ende eine einspringende Ringschulter 71, deren steckseitige ringförmige Stirnfläche 71a, vgl. Einzelheit "X", zum Zusammenwirken mit entsprechenden Gegenflächen an den Verdickungen 63 der Enden der federnden Segmente 62 bestimmt ist, während ihre kabelseitige, ringförmige Stirnfläche 71b als Anschlag für den Ringbund 65 der Kontakthülse 6 wirkt und die Verschiebung letzterer in Richtung der Steckseite des Steckverbinders begrenzt.The contact sleeve 6 is inserted under compression of the resilient segments 62 in a hollow screw 7 of the cable end side. The hollow screw 7 has near its plug-side end a re-entrant annular shoulder 71, the plug-side annular end face 71 a, see. Detail "X", intended to cooperate with corresponding mating surfaces on the thickenings 63 of the ends of the resilient segments 62, while their cable-side, annular end face 71b acts as a stop for the annular collar 65 of the contact sleeve 6 and the displacement of the latter in the direction of the mating side of the connector limited.

Die Hohlschraube 7 hat des weiteren ein Außengewinde 72, das in einer Ringnut 73 endet, an die sich in Richtung des Schraubkopfes 75 ein glatter Abschnitt 74 anschließt, dessen Durchmesser geringfügig kleiner als der Innendurchmesser der Ausnehmung 51 in deren kabelseitig von dem Innengewinde 53 liegenden Abschnitt ist. In der Ringnut 73 befindet sich ein O-Ring 8.The hollow screw 7 further has an external thread 72 which terminates in an annular groove 73, which is followed in the direction of the screw head 75, a smooth portion 74 whose diameter is slightly smaller than the inner diameter of the recess 51 in the cable side of the internal thread 53 lying section is. In the annular groove 73 is an O-ring. 8

In Fig. 2 ist die Hohlschraube 7 so weit in den Steckerkopf 5 eingedreht, daß der O-Ring 8 gerade auf den angefasten, kabelseitigen Stirnrand des Steckerkopfes 5 aufgelaufen ist. Die ersten Gewindegänge des Außengewindes 72 der Hohlschraube 7 greifen dabei in die ersten Gewindegänge des Innengewindes 53 des Steckerkopfes 5 ein. Diese Stellung der Hohlschraube 7 gegenüber dem Steckerkopf 5, die durch einen fühlbaren Anstieg des zum weiteren Eindrehen der Hohlschraube 7 erforderlichen Drehmomentes gekennzeichnet ist, markiert das Ende des ersten Spannweges und damit auch den Beginn des zweiten Spannweges der Hohlschraube 7. In diesem vormontierten Zustand wird der Steckverbinder normalerweise aus- bzw. zur Montage angeliefert.In Fig. 2 is the hollow screw 7 so far screwed into the plug head 5, that the O-ring 8 has just accumulated on the chamfered, cable-side end edge of the plug head 5. The first threads of the external thread 72 of the hollow screw 7 engage in the first thread of the internal thread 53 of the plug head 5 a. This position of the hollow screw 7 relative to the plug head 5, by a noticeable increase in the torque required for further screwing the hollow screw 7 is marked, marked the end of the first clamping path and thus also the beginning of the second clamping path of the hollow screw 7. In this pre-assembled state, the connector is usually off or delivered for assembly.

In Fig. 3 ist der wie in Fig. 2 gezeigt vormontierte Steckverbinder auf das entsprechend vorbereitete Ende eines ringgewellten Außenleiters 3 eines üblichen Koaxialkabels mit Dielektrikum 2 und rohrförmigem Innenleiter 1 aufgeschoben, uzw. so weit, bis der Stirnrand 31 des Kabelaußenleiters 3 die Kontakthülse 6 in die gezeichnete Position vorgeschoben hat, in der der Ringbund 65 der Kontakthülse 6 gegen die Ringschulter 71 der Hohlschraube 7 anliegt, so daß die Segmente 62 der Kontakthülse 6 durch den Stirnrand 31 des Kabelaußenleiters 3 auseinandergedrückt werden und dessen Endbereich 32 zwangsläufig in den Spalt s zwischen der Kegelringfläche 52 und die dazu im wesentlichen komplementären Gegenflächen der Verdickungen 63 an den Enden der federnden Segmente 62 gelangt. Dann wird bei festgehaltenem Steckerkopf 5 die Hohlschraube 7 in ersteren unter Zurücklegen des zweiten Abschnittes des Spannweges eingedreht, bis der in Fig. 4 dargestellte, endmontierte Zustand erreicht ist, in dem der Endbereich 32 des Kabelaußenleiters fest zwischen die Ringfläche 52 und die Verdickungen 63 der Kontakthülse 6 eingespannt und geklemmt ist.In Fig. 3 is like in Fig. 2 shown preassembled connector on the suitably prepared end of a ring waveguide outer conductor 3 of a conventional coaxial cable with dielectric 2 and tubular inner conductor 1 is pushed, uzw. so far until the end edge 31 of the cable outer conductor 3 has advanced the contact sleeve 6 in the position shown, in which the annular collar 65 of the contact sleeve 6 abuts against the annular shoulder 71 of the hollow screw 7, so that the segments 62 of the contact sleeve 6 through the end edge 31 of Cable outer conductor 3 are pressed apart and the end portion 32 inevitably passes into the gap s between the conical ring surface 52 and the complementary thereto complementary mating surfaces of the thickenings 63 at the ends of the resilient segments 62. Then, while holding the plug head 5, the hollow screw 7 is screwed into the former while covering the second section of the clamping path until the in Fig. 4 shown, final assembled state is reached, in which the end portion 32 of the cable outer conductor firmly between the annular surface 52 and the thickenings 63 of the contact sleeve 6 is clamped and clamped.

Fig. 5 zeigt eine zweite Ausführungsform des Steckverbinder im endmontierten Zustand. Diese zweite Ausführungsform entspricht weitgehend der ersten Ausführungsform gemäß den Figuren 1 bis 4, mit der Maßgabe, daß die Abfangung und Kontaktierung ähnlich wie aus der DE-A-43 44 328 bekannt ausgeführt ist. Die Bezugszeichen haben dieselbe Bedeutung wie in den Figuren 1 bis 4, ausgenommen im Bereich der Abfangung und Kontaktierung des Kabelaußenleiters 3 an bzw. mit dem Steckerkopf 5. Die Ausnehmung 51 des Steckerkopfes 5 hat bei dieser Ausführungsform statt der Kegelringfläche 53 (vgl. z.B. Fig. 1) eine im wesentlichen in einer Radialebene liegende Ringfläche 54, gegen die der flanschartig verformte Endbereich 33 des Kabelaußenleiters 3 verspannt ist. Dieser flanschartige Endbereich 33 bildet sich während des Eindrehens der Hohlschraube 7 um die Strecke des zweiten Abschnittes des Spannweges in die Ausnehmung 51 des Steckerkopfes 5 von selbst, denn die hier mit in einer Radialebene liegenden Stirnflächen ausgebildeten Verdickungen 63 an den Enden der federnden Segmente 62 der Kontakthülse 6 kommen in dem nicht dargestellten, der Fig. 3 entsprechenden Vormontagezustand in das erste Wellental des Kabelaußenleiters 3 zu liegen. Wenn sich der ursprüngliche Stirnrand des Kabelaußenleiters 3 wie im Fall der zuvor beschriebenen Ausführungsform in Höhe eines Wellenscheitels befindet, wird der Endbereich des Kabelaußenleiters einlagig flanschartig nach außen verformt. Befindet sich hingegen der ursprüngliche Stirnrand etwa in Höhe des nächsten steckseitigen Wellentales, so entsteht beim Eindrehen der Hohlschraube 7 über die Länge des zweiten Spannwegabschnittes die zeichnerisch dargestellte, doppellagige flanschartige Verformung des Endbereiches 33 des Kabelaußenleiters 3. Auch in diesem Fall hat das Zusammenwirken des Ringbundes 65 der Kontakthülse 6 mit der Ringschulter 71 der Hohlschraube 7 im Vormontagezustand dafür gesorgt, daß zwischen der kontaktierenden Ringfläche 54 und den Gegenflächen der Verdickungen 63 ein Spalt zur Aufnahme des Endbereiches 33 des Kabelaußenleiters 3 verbleibt. Fig. 5 shows a second embodiment of the connector in the final assembled state. This second embodiment largely corresponds to the first embodiment according to FIGS FIGS. 1 to 4 , with the proviso that the interception and contact similar to that from DE-A-43 44 328 is known known. The reference numerals have the same meaning as in the FIGS. 1 to 4 except in the area of the interception and contacting of the cable outer conductor 3 to or with the plug head 5. The recess 51 of the plug head 5 has in this embodiment, instead of the conical ring surface 53 (see, eg Fig. 1 ) located substantially in a radial plane annular surface 54, against which the flange-shaped end portion 33 of the cable outer conductor 3 is braced. This flange-like end portion 33 is formed during the screwing of the hollow screw 7 by the distance of the second portion of the clamping path in the recess 51 of the plug head 5 by itself, because the here formed in a radial plane end surfaces formed thickenings 63 at the ends of the resilient segments 62 of Contact sleeve 6 come in the not shown, the Fig. 3 corresponding preassembly state to lie in the first trough of the cable outer conductor 3. When the original end edge of the outer cable conductor 3 is at the level of a wave crest, as in the case of the previously described embodiment, the end portion of the outer cable conductor is deformed in a single flange outward manner. If, however, the original end edge is approximately at the level of the next plug-side wave trough, the dowel-shaped screw-shaped deformation of the end region 33 of the cable outer conductor 3 is formed when the hollow screw 7 is screwed in over the length of the second tensioning section. Also in this case, the interaction of the annular collar has 65 of the contact sleeve 6 with the annular shoulder 71 of the hollow screw 7 in Vormontagezustand ensured that between the contacting annular surface 54 and the opposite surfaces of the thickenings 63 a gap for receiving the end portion 33 of the cable outer conductor 3 remains.

Eine dritte Ausführungsform des Steckverbinders ist in Fig. 6 im vormontierten und in Fig. 7 im endmontierten Zustand dargestellt. Die Darstellung entspricht weitgehend derjenigen der Fig. 3 und 4, jedoch ist in Fig. 6 das Kabel weggelassen. Übereinstimmende Teile tragen die gleichen, jedoch gestrichenen Bezugszeichen. Fig. 6 zeigt den Steckerkopf 5' mit einem Außengewinde 53', an das sich eine Ringnut 55' anschließt, in der ein O-Ring 8' liegt. Auf seiner kabelseitigen Stirnfläche hat der Steckerkopf 5' eine Kegelringfläche 52'. Auf den Steckerkopf 5' ist eine Überwurfhülse 7' mit Innengewinde 72' so weit aufgeschraubt, daß ihr steckseitiger Stirnrand auf den O-Ring 8' aufgelaufen ist. Die Überwurfhülse 7' hat eine einspringende Ringschulter 71' und umschließt eine Kontakthülse 6', die den gleichen Aufbau wie die Kontakthülse 6 z.B. in Fig. 1 hat.A third embodiment of the connector is in Fig. 6 in pre-assembled and in Fig. 7 shown in the final assembled state. The presentation largely corresponds to that of 3 and 4 , however, is in Fig. 6 the cable is omitted. Matching parts carry the same but painted reference numerals. Fig. 6 shows the plug head 5 'with an external thread 53', to which an annular groove 55 'connects, in which an O-ring 8' is located. On its cable-side end face of the plug head 5 'has a cone ring surface 52'. On the plug head 5 'is a cap sleeve 7' with internal thread 72 'screwed so far that their plug-side end edge on the O-ring 8' accumulated. The cap sleeve 7 'has a re-entrant annular shoulder 71' and encloses a contact sleeve 6 ', which has the same structure as the contact sleeve 6, for example in Fig. 1 Has.

Der Montagevorgang verläuft, wie anhand der Figuren 1 bis 4 beschrieben. Der endmontierte Zustand ist in Fig. 7 dargestellt.The assembly process proceeds, as based on the FIGS. 1 to 4 described. The final assembled state is in Fig. 7 shown.
