In addition, the screen the line must be connected to the coupling element without interruption.

Aus der EP 0 128 472 A2 geht ein Kupplungselement hervor, bei dem die Leiter einer elektrischen Leitung an Endkontakte angeschlossen sind, die innerhalb eines zylindrischen Gehäuses angeordnet und in demselben mittels Isoliermaterials festgelegt sind. Das am Ende der Leitung angebrachte Gehäuse ist von einem gespritzten Schutzkörper umgeben und durch Endkontakte und Isoliermaterial vollständig ausgefüllt. Die Endkontakte liegen unverrückbar im Gehäuse fest. Zusätzlich hat das Kupplungselement einen Block aus Isoliermaterial mit doppelseitigen Kontaktelementen, der lösbar auf das Gehäuse aufgeschraubt ist. Er kann ausgetauscht werden, wenn beschädigte Kontaktelemente ersetzt werden sollen. Die Kontaktelemente greifen im zusammengebauten Kupplungselement in die im Gehäuse befindlichen Endkontakte ein. Bei dem bekannten Kupplungselement nach der eingangs erwähnten DE 30 34 415 A1, die als nächstliegenden Stand der Technik angesehen wird, ist das leitungsseitige Ende eines metallischen Adapters als Ansatz ausgebildet, dessen radiale Abmessungen gegenüber den Abmessungen eines an der Anschlußseite liegenden Griffteils des Adapters kleiner sind. In dem Ansatz ist mit Abstand von seinem leitungsseitigen Ende eine umlaufende, nutförmige Vertiefung angebracht. Der Ansatz weist weiterhin mindestens eine axial verlaufende, vom leitungsseitigen Ende bis zur Vertiefung reichende Ausnehmungen zur Aufnahme eines bis in die Vertiefung geführten Zugorgans der Leitung auf. An dem Ansatz ist außerdem eine bis über die Leitung ragende, fest am Ansatz anliegende metallische Hülse angebracht, welche auch den mit dem Ansatz verbundenen Schirm der Leitung abdeckt. Um das leitungsseitige Ende des Grundkörpers und das Ende der Leitung ist ein aus Isoliermaterial bestehender Griffkörper herumgespritzt. Dieses Kupplungselement ist mit sicherer Kontaktierung des Schirms feuchtigkeitsdicht am Ende der Leitung angebracht. Es kann jedoch nicht zerstörungsfrei vom Leitungsende entfernt werden. Zur Beseitigung von Fehlern und für eine Änderung der Positionen der Kontaktelemente im Kupplungsteil muß dasselbe daher jeweils neu montiert werden.EP 0 128 472 A2 discloses a coupling element in which the conductor has a electrical line connected to end contacts within a cylindrical Housing arranged and fixed in the same by means of insulating material. The most Housing attached to the end of the line is surrounded by an injection-molded protective body and completely filled by end contacts and insulating material. The end contacts are fixed in the housing. In addition, the coupling element has a block Insulating material with double-sided contact elements that can be detached from the housing is screwed on. It can be replaced when damaged contact elements are replaced should be. The contact elements engage in the assembled coupling element the end contacts in the housing. In the known coupling element according to DE 30 34 415 A1 mentioned at the beginning, which is considered the closest prior art, is the line-side end of a metallic adapter designed as an extension, the radial dimensions versus the dimensions of one on the connection side lying handle part of the adapter are smaller. In the approach is at a distance from his a circumferential, groove-shaped recess is attached to the line end. The approach also has at least one axially extending from the line end to Recesses extending recesses for receiving a guided into the recess Zugorgans the line on. At the approach is also one to the line protruding, metal sleeve firmly attached to the neck, which also with the the shield of the line connected to the approach. To the line end of the The base body and the end of the line is an insulating material Handle body sprayed around. This coupling element is with secure contacting of the The moisture-proof shield is attached to the end of the cable. However, it cannot be removed non-destructively from the cable end. To eliminate errors and for a change in the positions of the contact elements in the coupling part must be the same therefore be reassembled.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs geschilderte Kupplungselement mit zugehörigem Verfahren unter Beibehaltung einer feuchtigkeitsdichten Anordnung an der Leitung und der nicht unterbrochenen Schirmung demontierbar auszuführen.The invention has for its object the coupling element described above with associated procedure while maintaining a moisture-tight arrangement the cable and the uninterrupted shielding must be removable.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß der Adapter einen vom Isoliermaterial des Schutzkörpers freien Hohlraum zur Aufnahme von Vorratslängen der Leiter aufweist und
  • daß am Adapter an seinem der Leitung abgewandten Ende eine denselben umgreifende, um ihre Achse frei drehbare metallische Hülse mit einem Innengewinde unverlierbar angebracht ist, in welche ein mit einem Gewindestutzen ausgerüsteter, den Kontaktträger umschließender Steckerkörper mit feuchtigkeitsdichter Anlage am Adapter eingeschraubt ist.
According to the invention, this object is achieved by
  • that the adapter has a cavity free of the insulating material of the protective body for receiving supply lengths of the conductors and
  • that the adapter at its end facing away from the line encompasses a captive metallic sleeve with an internal thread that can be freely rotated about its axis and into which a plug body equipped with a threaded connector and enclosing the contact carrier is screwed into the adapter with a moisture-proof system.

Der Hohlraum zur Aufnahme der Vorratslängen der Leiter wird durch eine Abdeckung erzeugt, welche die Leiter während des Spritzgießens des Schutzkörpers umgibt und an der Wandung des Adapters anliegt. The cavity for receiving the supply lengths of the conductors is covered by a cover generated, which surrounds the conductor during the injection molding of the protective body and on lies against the wall of the adapter.

Dieses Kupplungselement ist durch den aufgespritzten Schutzkörper feuchtigkeitsdicht ausgeführt und mit der Leitung verbunden. Es ist trotzdem ohne Beschädigungsgefahr demontierbar, weil der Steckerkörper mittels der Hülse von Adapter gelöst werden kann. Die beim Zusammenbau des Kupplungselements an sich zu langen Leiter der Leitung sind als Vorratslängen im Hohlraum des Adapters aufgenommen und dort gegen Beschädigungen geschützt. Die Vorratslängen der Leiter gestatten bei geöffnetem Kupplungselement eine problemlose Handhabung der Leiter mit daran angebrachten Kontaktelementen. Das Kupplungselement kann daher im Bedarfsfall jederzeit geöffnet werden, so daß beispielsweise die Positionen der Kontaktelemente im Kontaktträger geändert werden können. Es braucht dazu nur die metallische Hülse so gedreht zu werden, daß der Steckerkörper aus derselben heraus bewegt wird. Der Kontaktträger steht dann für Manipulationen beliebiger Art zur Verfügung. Es können also auch Messungen zur Fehlersuche durchgeführt werden. Anschließend wird der Steckerkörper mit dem Kontaktträger wieder durch Drehung der Hülse in dieselbe hineingeschraubt. Der Kontaktträger wird weder beim Schließen noch beim Öffnen des Kupplungselements gedreht. Er wird jeweils nur in axialer Richtung bewegt. Die angeschlossenen Leiter werden also nicht verdreht, sondern ebenfalls nur in axialer Richtung zu den Vorratslängen zusammengeschoben bzw. wieder in die Länge gezogen.This coupling element is moisture-proof due to the sprayed-on protective body executed and connected to the line. Nevertheless, there is no risk of damage removable, because the plug body can be detached from the adapter by means of the sleeve. The conductor of the line, which is too long when assembling the coupling element are included as supply lengths in the cavity of the adapter and there against Damage protected. The supply lengths of the ladder allow when open Coupling element easy handling of the ladder with attached Contact elements. The coupling element can therefore be opened at any time if necessary so that, for example, the positions of the contact elements in the contact carrier can be changed. All you need to do is turn the metal sleeve so that it is turned be that the plug body is moved out of the same. The contact carrier is then available for manipulations of any kind. So it can too Measurements for troubleshooting are carried out. Then the connector body screwed back into the contact carrier by rotating the sleeve. The contact carrier is neither when closing nor when opening the coupling element turned. It is only moved in the axial direction. The connected conductors are not twisted, but also only in the axial direction to the Supply lengths pushed together or stretched again.

  • Das Kupplungselement K nach den Fig. 1 und 2 ist am Ende einer geschirmten elektrischen Leitung 1 angebracht. Es hat einen durch Spritzgießen hergestellten Schutzkörper 2, welcher die Leitung 1 und einen hülsenförmigen, metallischen Adapter A teilweise feuchtigkeitsdicht umschließt. Der Adapter A besteht aus zwei miteinander verschraubbaren Teilen 3 und 4, zwischen denen im Montagezustand der beispielsweise als Geflecht aus Kupferdrähten bestehende, flexible Schirm 5 der Leitung 1 eingeklemmt ist. Die Leitung 1 hat mindestens zwei isolierte elektrische Leiter 6, die von dem gemeinsamen Schirm 5 umgeben sind. Vorzugsweise ist die Leitung 1 mit einer größeren Anzahl von Leitern 6 ausgerüstet. Über dem Schirm 5 ist ein Mantel aus Isoliermaterial angebracht.The coupling element K according to FIGS. 1 and 2 is shielded at the end electrical line 1 attached. It has one made by injection molding Protective body 2, which the line 1 and a sleeve-shaped, metallic adapter A partially encloses moisture-proof. The adapter A consists of two together screwable parts 3 and 4, between which in the assembled state, for example as a braid made of copper wires, flexible shield 5 of line 1 clamped is. The line 1 has at least two insulated electrical conductors 6, which of the common screen 5 are surrounded. The line 1 is preferably of a larger size Number of conductors 6 equipped. Over the screen 5 is a jacket made of insulating material appropriate.

    Am freien, der Leitung 1 abgewandten Ende des Adapters A ist eine metallische Hülse 7 unverlierbar, aber frei drehbar an demselben angebracht. Die Hülse 7 hat ein Innengewinde. In die Hülse 7 ist im fertigen Kupplungselement K gemäß Fig. 1 ein metallischer Steckerkörper 8 mittels eines zu demselben gehörenden Gewindestutzens 9 eingeschraubt. Zwischen Steckerkörper 8 und Adapter A liegt eine ringförmige Dichtung 10, beispielsweise ein O-Ring. Der Steckerkörper 8 kann außen Teile einer Verriegelung haben, beispielsweise Teile eines Bajonettverschlusses.At the free end of the adapter A facing away from the line 1 is a metallic sleeve 7 captive, but freely rotatable attached to the same. The sleeve 7 has a Inner thread. In the sleeve 7 is in the finished coupling element K according to FIG. 1 metallic plug body 8 by means of a threaded connector 9 belonging to the same screwed. Between the plug body 8 and adapter A there is an annular seal 10, for example an O-ring. The connector body 8 can be part of a lock on the outside have, for example parts of a bayonet lock.

    An den Enden der dort abisolierten Leiter 6 der Leitung 1 sind gemäß Fig. 2 Kontaktelemente 11 angebracht, die im fertigen Kupplungselement K in einen aus mechanisch stabilem Kunststoff bestehenden Kontaktträger 12 eingeschoben sind. Der mit den Kontaktelementen 11 bestückte Kontaktträger 12 liegt im fertigen Kupplungselement K innerhalb des Steckerkörpers 8. Die Kontaktelemente 11 sind dann für Gegenkontakte eines Steckers oder eines Geräts zugänglich.According to FIG. 2, at the ends of the conductors 6 of the line 1 stripped there are stripped Contact elements 11 attached, in the finished coupling element K in one mechanically stable plastic existing contact carrier 12 are inserted. The with the contact elements 11 equipped contact carrier 12 is in the finished Coupling element K within the plug body 8. The contact elements 11 are then accessible for mating contacts of a plug or device.

    Das Kupplungselement K wird beispielsweise wie folgt am Ende der Leitung 1 angebracht:The coupling element K is, for example, as follows at the end of line 1 appropriate:

    Am Ende der Leitung 1 wird deren Mantel auf einer ausreichenden Länge entfernt, so daß der Schirm 5 und die von demselben umschlossenen Leiter 6 zugänglich sind. Der Schirm 5 wird danach zur Freigabe einer größeren Länge der Leiter 6 verkürzt und beispielsweise rosettenförmig aufgeweitet. Anschließend werden die Leiter 6 durch den Adapter A geschoben. Der aufgeweitete Schirm 5 wird dann zwischen den Teilen 3 und 4 des Adapters A eingeklemmt, so daß die Schirmung ununterbrochen bis zur Hülse 7 geführt ist. At the end of line 1, its jacket is removed to a sufficient length, so that the screen 5 and the conductor 6 enclosed by the same are accessible. The Screen 5 is then shortened to release a greater length of the conductor 6 and for example, expanded like a rosette. Then the conductor 6 through the Adapter A pushed. The expanded screen 5 is then between the parts 3 and 4 of the adapter A clamped, so that the shielding continuously up to the sleeve 7 is led.

    Über die Leiter 6 wird anschließend bei dem so vorbereiteten Leitungsende eine rohrförmige Abdeckung 13 geschoben, welche die Leiter 6 möglichst dicht umschließt und an der Wandung des Adapters A, hier also am Teil 3 desselben anliegt. Der aus Fig. 3 ersichtliche Hohlraum H des Adapters A ist dann nahezu vollständig von der Abdeckung 13 ausgefüllt. In einem Spritzgießwerkzeug wird anschließend der Schutzkörper 2 um das Ende der Leitung 1 und das leitungsseitige Ende des Adapters A herumgespritzt. Die Abdeckung 13 sorgt dabei dafür, daß das Spritzmaterial nicht in den Adapter A eindringt. Insbesondere dessen der Leitung 1 abgewandte Öffnung und die Hülse 7 bleiben dadurch frei vom Spritzmaterial. Die der Leitung 1 zugewandte Öffnung des Adapters A, durch welche die Leiter 6 in denselben eingeführt werden, kann vor dem Spritzgießen des Schutzkörpers 2 ebenfalls abgedichtet werden. Dazu kann im Bereich R (Fig. 2) ein Dichtungsmittel aufgebracht werden, bei dem es sich beispielsweise um ein Zweikomponenten-Gießharz oder einen Schmelzkleber handeln kann. Nach Beendigung des Spritzgießvorgangs wird die Abdeckung 13 entfernt, so daß sich der Hohlraum H ergibt, in dem sich die Leiter 6 befinden.The conductor 6 is then used at the line end thus prepared tubular cover 13 pushed, which encloses the conductor 6 as tightly as possible and on the wall of the adapter A, so here on part 3 of the same. The one out Fig. 3 apparent cavity H of the adapter A is then almost completely from the Cover 13 filled out. The is then in an injection mold Protective body 2 around the end of line 1 and the line end of adapter A splashed. The cover 13 ensures that the spray material is not in the Adapter A penetrates. In particular, its opening facing away from line 1 and the Sleeve 7 remain free of spray material. The opening facing line 1 of the adapter A, through which the conductors 6 are inserted into the same, can before Injection molding of the protective body 2 can also be sealed. For this purpose, in area R (Fig. 2) a sealant can be applied, which is for example a Two-component cast resin or a hot melt adhesive can act. After completion the injection molding process, the cover 13 is removed so that the cavity H results in which the conductors 6 are located.

    Die Enden der Leiter 6 werden daraufhin abisoliert. Danach werden die Kontaktelemente 11 an den Leitern 6 elektrisch leitend befestigt, beispielsweise durch Crimpen. Die Kontaktelemente 11 werden dann beispielsweise nach einem vorgegebenem Schema in Durchgangslöcher 14 des Kontaktträgers 12 eingeschoben. Dazu können sowohl die Leiter 6 bzw. deren Kontaktelemente 11 als auch die Durchgangslöcher 14 markiert bzw. codiert sein. Es ist dann eine genaue Zuordnung eines jeden Leiters zu einem Durchgangsloch möglich.The ends of the conductor 6 are then stripped. After that, the contact elements 11 attached to the conductors 6 in an electrically conductive manner, for example by crimping. The Contact elements 11 are then, for example, in accordance with a predetermined scheme Through holes 14 of the contact carrier 12 inserted. Both the Marked conductor 6 or their contact elements 11 and the through holes 14 or be encoded. It is then an exact assignment of each leader to one Through hole possible.

    Der Steckerkörper 8 mit dem darin befindlichen Kontaktträger 12 wird dann an die Hülse 7 herangebracht. Durch Drehung der Hülse 7 wird der Steckerkörper 8 mit dem Kontaktträger 12 in Richtung des Adapters A gezogen. Die Leiter 6 werden dabei in axialer Richtung zusammengeschoben und als Vorratslängen im Hohlraum H des Adapters A gelagert. In der Endposition liegt der Steckerkörper 8 mit seinem Gewindeflansch 9 an der Dichtung 10 an. Um ein unerwünschtes Lösen des Steckerkörpers 8 von der Hülse 7 zu vermeiden, kann vor dem Zusammenbau ein Kleber auf den Gewindestutzen 9 aufgebracht werden. The connector body 8 with the contact carrier 12 located therein is then connected to the Sleeve 7 brought up. By rotating the sleeve 7, the connector body 8 with the Contact carrier 12 pulled in the direction of the adapter A. The head 6 are in axially pushed together and as stock lengths in the cavity H des Adapters A stored. In the end position, the plug body 8 lies with his Threaded flange 9 on the seal 10. To an undesirable loosening of the To avoid plug body 8 from the sleeve 7, an adhesive before assembly be applied to the threaded connector 9.

    Für eine eventuelle Demontage des Kupplungselements K, die beispielsweise für eine Veränderung von Positionen der Kontaktelemente 11 im Kontaktträger 12 erforderlich sein kann, wird zunächst der Kleber durch Wärmezufuhr von außen aufgeweicht. Danach kann der Steckerkörper 8 durch Drehung der Hülse 7 wieder aus derselben herausgedreht werden. Die Leiter 6 werden dabei aus ihrer zusammengeschobenen Vorratsposition wieder in die Länge gezogen. Die Kontaktelemente 11 können dann für eine Veränderung der Position einzelner oder aller Kontaktelemente 11 aus dem Kontaktträger 12 herausgenommen und in geänderter Position wieder in dessen Durchgangslöcher 14 eingesteckt werden. Anschließend wird das Kupplungselement K, wie schon beschrieben, wieder zusammengebaut.For a possible disassembly of the coupling element K, for example for a Change of positions of the contact elements 11 in the contact carrier 12 required may be, the adhesive is first softened by applying heat from the outside. Thereafter, the plug body 8 can be removed from the same by rotating the sleeve 7 be unscrewed. The conductors 6 are pushed together from her Extended the stock position. The contact elements 11 can then for a change in the position of individual or all contact elements 11 from the Contact carrier 12 removed and in the changed position again in its Through holes 14 are inserted. Then the coupling element K, reassembled as already described.
