Description

Die Erfindung betrifft einen Steckverbinder für elektrische Kabel, bestehend aus einem im wesentlichen zylindrischen Gehäuse, das mit dem Kabel verbundene Kontaktelemente aufnimmt, und einer flexiblen Schutzummantelung am Übergang des Kabels in das Gehäuse.The invention relates to a connector for electrical cables, consisting of a substantially cylindrical housing which receives contact elements connected to the cable, and a flexible protective sheath at the transition of the cable into the housing.

Bei derartigen Steckverbindern dient die Schutzummantelung einerseits dazu, das Eindringen von Feuchtigkeit oder Dämpfen in das Steckergehäuse zu verhindern; andererseits hat sie die Aufgabe, eine feste, nicht mehr lösbare Verbindung zwischen dem Gehäuse und dem Kabel herzustellen. Derartige Schutzummantelungen werden bisher durch eine Vergussmasse gebildet, die vom Hersteller mit üblichen Verfahren der plastischen Umformung angebracht werden. Der Anwender hat damit keine Möglichkeit, Ummantelungen seiner Wahl vorzusehen, beispielsweise mit einer Beschriftung oder einer besonderen Farbgebung.In such connectors, the protective sheath serves on the one hand to prevent the ingress of moisture or vapors into the connector housing; On the other hand, it has the task of making a solid, no longer detachable connection between the housing and the cable. Such protective sheaths are previously formed by a potting compound, which are attached by the manufacturer with conventional plastic deformation methods. The user has no way to provide sheathing of his choice, for example, with a label or a special color.

Der Erfindung liegt die Aufgabe zugrunde, einen Steckverbinder der eingangs umrissenen Bauart zur Verfügung zu stellen, bei der die Schutzummantelung eine individuelle Konfektionierung gestattet, z. B. hinsichtlich Farbe oder Beschriftung, die gleichwohl Sicherheit gegen jegliche Manipulationen bietet.The invention has for its object to provide a connector of the type outlined at the outset, in which the protective coating allows individual assembly, z. B. in terms of color or lettering, which nevertheless provides security against any manipulation.

Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, dass die Schutzummantelung aus einer auf das Kabel aufgeschobene Schutztülle besteht, die mit einer das Gehäuse übergreifenden Schutzhülse axial fest verbunden ist, welche ihrerseits axial fest am Gehäuse fixiert ist.To achieve this object, it is provided according to the invention that the protective casing consists of a pushed onto the cable protective sleeve, which is axially fixedly connected to the housing cross-protective sleeve, which in turn is fixed axially fixed to the housing.

Mit dieser Lösung steht ein Steckverbinder zur Verfügung, bei dem der Anwender die Möglichkeit hat, vor dem Einsatz Schutzhülsen und gegebenenfalls auch Schutztüllen seiner Wahl anzubringen, wobei nach der Fixierung eine nicht mehr lösbare Verbindung zwischen Gehäuse, Schutzhülse und Schutztülle geschaffen ist. Beim Versuch, einen derartigen Steckverbinder zu öffnen, würde die Ummantelung zerstört.With this solution, a connector is available, in which the user has the opportunity, before use protective sleeves and possibly also protective sheaths of his Choice to install, wherein after fixing a no longer detachable connection between the housing, protective sleeve and protective sleeve is created. Attempting to open such a connector would destroy the shroud.

Für die formschlüssige Verbindung zwischen der Schutztülle und der Schutzhülse einerseits und der Schutzhülse und dem Gehäuse andererseits ist in Weiterbildung der Erfindung ein stufenförmige Klemmring vorgesehen, der mit seiner radial kleineren Stufe in eine Ringnut der Schutztülle eingreift und eine Außenverzahnung hat, die in Rasteingriff mit einer Innenverzahnung der Schutzhülse ist, während seine radial größere Stufe mit einer Innenverzahnung in eine Außenverzahnung des Gehäuses einrastet. Zur unlösbaren Verbindung zwischen diesen drei Bauteilen ist somit nur ein einziges Bauelement in Form des stufenförmigen Klemmrings erforderlich, der die gegenseitige Fixierung der Bauelemente gewährleistet.For the positive connection between the protective sleeve and the protective sleeve on the one hand and the protective sleeve and the housing on the other hand, a step-shaped clamping ring is provided in the invention, which engages with its radially smaller step in an annular groove of the protective sleeve and has an external toothing, which in latching engagement with a Internal toothing of the protective sleeve, while its radially larger step engages with an internal toothing in an outer toothing of the housing. For permanent connection between these three components thus only a single component in the form of the stepped clamping ring is required, which ensures the mutual fixation of the components.

Es ist besonders vorteilhaft, wenn in Weiterbildung der Erfindung die Schutztülle Entlastungsaussparungen aufweist. Eine derartige Schutztülle übernimmt damit die Funktion eines Knickschutzes am kritischen Übergang zwischen dem Gehäuse und dem Kabel.It is particularly advantageous if, in a further development of the invention, the protective sleeve has relief recesses. Such a protective sleeve thus assumes the function of a kink protection at the critical transition between the housing and the cable.

Nach einem weiteren Merkmal der Erfindung ist das in das Gehäuse eingreifende Ende der Schutztülle formschlüssig mit einem Kronenring verbunden, dessen axial zungenförmig abstehende Zacken in einen Ringraum eines ringförmigen Schirmelementes mit im Querschnitt einem U-Profil eingreifen, wobei der Ringraum die aufgewickelten Enden eines Kabelschirms aufnimmt.According to a further feature of the invention engaging in the housing end of the protective sleeve is positively connected to a crown ring, the axially tongue-shaped protruding teeth engage in an annular space of an annular shield member having a U-profile in cross-section, wherein the annulus receives the wound ends of a cable shield ,

Eine derartige, aus Kronenring und Schirmelement bestehende Wickelvorrichtung für die Enden eines Kabelschirms sind grundsätzlich bekannt, beispielsweise aus DE 199 44 167 B4 der Anmelderin.Such, consisting of crown ring and shield element winding device for the ends of a cable shield are basically known, for example DE 199 44 167 B4 the applicant.

In weiterer Ausgestaltung dieses Lösungsmerkmals ist in dem Kronenring ein vom radial inneren Profilschenkel des Schirmelementes beaufschlagter Klemmkonus angebracht, der beim Aufschieben des Schirmelementes in seine Endstellung den vorzugsweise segmentierten Klemmkonus gegen den Mantel des Kabels drückt, so dass damit eine Zugentlastung hergestellt ist.In a further embodiment of this feature, a solution acted upon by the radially inner profile leg of the shield element clamping cone is mounted in the crown ring, which pushes the preferably segmented clamping cone against the jacket of the cable when pushing the shield element into its end position, so that thus a strain relief is made.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Schutzansprüchen und aus der folgenden Beschreibung eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist. Es zeigen:

  • Figur 1 eine Explosionsdarstellung eines Steckverbinders in einer ersten Phase des Zusammenbaus,
  • Figur 2 den Steckverbinder der Figur 1 in einer anschließenden Montagephase und
  • Figur 3 einen Längsschnitt durch den zusammengebauten Steckverbinder der Figuren 1 und 2.
Further features and advantages of the invention will become apparent from the claims and from the following description of an embodiment, which is illustrated in the drawing. Show it:
  • FIG. 1 an exploded view of a connector in a first phase of the assembly,
  • FIG. 2 the connector of FIG. 1 in a subsequent assembly phase and
  • FIG. 3 a longitudinal section through the assembled connector of FIGS. 1 and 2 ,

Der in den Figuren insgesamt mit 10 bezeichnete Steckverbinder hat eine metallisches, im wesentlichen zylindrisches Gehäuse 12, das stiftförmige Kontaktelemente 14 aufnimmt, die mit einem Kabel 16 verbunden sind. Die Kontaktelemente 14 sind in bekannter Weise in einem Isolierkörper 18 aus Kunststoff formschlüssig fixiert, welcher seinerseits in einem Haltezylinder 20 angebracht ist. Wie Figur 3 weiter zeigt, sitzt diese Haltezylinder 20 in dem Gehäuse 12, auf dessen in Figur 3 rechtes Ende eine zylindrische Hülse 22 aufgesetzt ist, welche durch einen Sprengring 24 axial fixiert ist.The generally designated 10 in the figures connector has a metallic, substantially cylindrical housing 12 which receives pin-shaped contact elements 14 which are connected to a cable 16. The contact elements 14 are positively fixed in a known manner in an insulating body 18 made of plastic, which in turn is mounted in a holding cylinder 20. As FIG. 3 further shows, this holding cylinder 20 is seated in the housing 12, on the in FIG. 3 right end, a cylindrical sleeve 22 is placed, which is axially fixed by a snap ring 24.

Im gegenüberliegenden Endbereich nimmt das Gehäuse 12 ein ringförmiges Schirmelement 26 auf, das im Querschnitt die Profilform eines liegenden U hat, dessen radial innerer und längerer Profilschenkel 28 in einen Kronenring 30 eingreift, während sich der in Figur 3 radial verlaufende Boden 32 des Schirmelementes 26 am Haltezylinder 20 abstützt.In the opposite end portion of the housing 12 receives an annular shield member 26 which has the profile shape of a horizontal U in cross section, the radially inner and longer profile leg 28 engages in a crown ring 30, while the in FIG. 3 radially extending bottom 32 of the shield element 26 on the holding cylinder 20 is supported.

Wie in der erwähnten DE 199 44 167 ausführlich erläutert, dient das Schirmelement 26 beim Aufsetzen auf den Kronenring 30 und einer Drehung relativ zu diesem zum Aufwickeln der Enden eines Kabelschirms 34.As in the mentioned DE 199 44 167 explained in detail, the shield member 26 serves when placed on the crown ring 30 and a rotation relative thereto for winding the ends of a cable shield 34th

Nach einem Merkmal der Erfindung ist in dem Kronenring 30 mit seinen axial abstehenden Zacken 36 ein Klemmkonus 38 angebracht oder einstückig mit diesem ausgebildet, der - wie die Figuren 1 und 2 zeigen - in einzelne Klemmsegmente 40 unterteilt ist. Im zusammengebauten Zustand des Steckverbinders 10 werden dieses Klemmsegmente 40 durch den radial inneren und längeren Profilschenkel 28 des Schirmelementes 26 über einen Sperrring 42 radial gegen den Mantel des Kabels 16 gedrückt, wodurch eine Zugentlastung hergestellt ist. Aus Figur 2 geht hervor, dass der Sperrring 42 an seiner dem Klemmkonus 38 zugewandten Seite eine Verzahnung 44 aufweist, die in Rasteingriff mit einer Stirnverzahnung 46 kommt, welche am Klemmkonus 38 ausgebildet ist.
Im Beispiel der Figur 1 ist zu erkennen, dass beim Zusammenbau der Klemmkonus 38 zwischen dem eigentlichen Kronenring 30 und einer diesen ergänzenden Ringhälfte 38' eingeklemmt wird.According to a feature of the invention, a clamping cone 38 is mounted in the crown ring 30 with its axially projecting teeth 36 or formed integrally therewith, which - like the FIGS. 1 and 2 show - is divided into individual clamping segments 40. In the assembled state of the connector 10 of this clamping segments 40 are pressed by the radially inner and longer profile leg 28 of the shield member 26 via a locking ring 42 radially against the jacket of the cable 16, whereby a strain relief is made. Out FIG. 2 It is apparent that the locking ring 42 at its the clamping cone 38th facing side has a toothing 44 which comes into latching engagement with a spur gear teeth 46, which is formed on the clamping cone 38.
In the example of FIG. 1 It can be seen that during assembly of the clamping cone 38 between the actual crown ring 30 and a supplementary ring half 38 'is clamped.

Wie die Figuren weiter zeigen, ist gemäß der Erfindung am Übergang des Kabels 10 in das Gehäuse 12 eine flexible Schutztülle 48 aus elastischem Werkstoff vorgesehen, deren in Figur 3 rechtes Ende in das Gehäuse 12 eingreift. Im zusammengebauten Zustand der Steckverbindung 10 gemäß Figur 3 ist die Schutztülle 48 axial fest mit einer Schutzhülse 50 verbunden, die ebenfalls aus Kunststoff hergestellt sein kann und ihrerseits axial fest am Gehäuse 12 fixiert ist. Zur gegenseitigen Fixierung dient ein stufenförmiger Klemmring 52. Der Klemmring 52 greift mit seiner radial kleineren Stufe 54 in eine Ringnut 56 der Schutztülle 48 ein und hat eine Außenverzahnung 58, die in Rasteingriff mit einer Innenverzahnung 60 der Schutzhülse 50 ist. Die radial größere Stufe 62 des Klemmrings 52 rastet mit einer Innenverzahnung in eine Außenverzahnung 64 des Gehäuses 12 ein.As the figures further show, according to the invention at the junction of the cable 10 in the housing 12, a flexible protective sleeve 48 made of elastic material is provided, whose in FIG. 3 right end engages in the housing 12. In the assembled state of the connector 10 according to FIG. 3 the protective sleeve 48 is axially fixedly connected to a protective sleeve 50, which may also be made of plastic and in turn is fixed axially fixed to the housing 12. For mutual fixation is a stepped clamping ring 52. The clamping ring 52 engages with its radially smaller step 54 in an annular groove 56 of the protective sleeve 48 and has an external toothing 58 which is in locking engagement with an internal toothing 60 of the protective sleeve 50. The radially larger step 62 of the clamping ring 52 engages with an internal toothing in an external toothing 64 of the housing 12.

In Figur 3 ist schließlich angedeutet, dass zur weiteren axialen Sicherung das in das Gehäuse 12 eingreifende Ende der Schutztülle 48 einen nach innen vorspringenden Absatz 66 hat, der in eine Ringnut 68 (vgl. Figur 2) des Kronenrings 30 mit Schnappsitz eingreift.In FIG. 3 Finally, it is indicated that for further axial securing the engaging in the housing 12 end of the protective sleeve 48 has an inwardly projecting shoulder 66 which in an annular groove 68 (see. FIG. 2 ) of the crown ring 30 engages with snap fit.

Erfindungswesentlich ist schließlich, dass die elastische Schutztülle 48 Entlastungsaussparungen 70 aufweist, so dass sie einen wirksamen Knickschutz für das Kabel 16 am Übergang in das Gehäuse 12 herstellt.Finally, it is essential to the invention that the elastic protective sleeve 48 has relief recesses 70, so that it produces an effective kink protection for the cable 16 at the transition into the housing 12.

Beim Zusammenbau des Steckverbinders 10 wird in der folgenden Weise vorgegangen:When assembling the connector 10, the procedure is as follows:

In einem ersten Schritt wird der den Klemmkonus 38 einschließende Kronenring 30 über seine Ringnut 68 auf den Absatz 66 der Schutztülle 48 aufgesteckt, wonach die Enden des Kabelschirmes 34 zwischen die Zacken 36 des Kronenrings 30 gelegt werden. Anschließend wird durch Drehen und gleichzeitig axiales Aufschieben des Schirmelementes 26 der Kabelschirm in den Ringraum des Schirmelementes 26 gewickelt, bis dieses durch Schnappeingriff axial in einer Ringnut des Kronenrings 30 fixiert ist.In a first step, the crown ring 30 enclosing the clamping cone 38 is slipped over its annular groove 68 onto the shoulder 66 of the protective sleeve 48, after which the ends of the cable shield 34 are placed between the teeth 36 of the crown ring 30. Subsequently, the cable screen is wound into the annular space of the shielding element 26 by turning and at the same time axially pushing the shielding element 26 until it is fixed axially by snap engagement in an annular groove of the crowned ring 30.

In dieser Endstellung des Schirmelementes 36 drückt dessen radial innerer, längerer Profilschenkel 28 über den Sperrring 42 gegen die Klemmsegmente 40 des Klemmkonus 38, so dass diese aus ihrer konischen Ausgangsposition in eine in Figur 3 gezeigte Stellung gelangen, in der sie in einer Ebene liegen und gegen den Mantel des Kabels 16 drücken. Damit ist eine Zugentlastung hergestellt.In this end position of the shield element 36 presses its radially inner, longer profile leg 28 on the locking ring 42 against the clamping segments 40 of the clamping cone 38, so that these from its conical starting position in an in FIG. 3 shown position in which they lie in a plane and press against the jacket of the cable 16. This is a strain relief is made.

In einem weiteren Schritt wird nun die so hergestellte Baugruppe in das Gehäuse 12 eingeschoben, worauf, wie sich aus Figur 3 ergibt, der stufenförmige Klemmring 52 mit seiner größeren Stufe 62 und seiner darin ausgebildeten Innenverzahnung, die in die Außenverzahnung 64 des Gehäuses 12 eingreift, eine axial feste Verbindung mit dem Gehäuse 12 herstellt. Gleichzeitig schnappt die kleinere Stufe 54 des Klemmringes 52 in die Ringnut 56 der Schutztülle 48 ein.In a further step, the assembly thus produced is now inserted into the housing 12, whereupon, as is apparent from FIG. 3 shows, the stepped clamping ring 52 with its larger step 62 and its internal teeth formed therein, which engages in the external toothing 64 of the housing 12, an axially fixed connection with the housing 12 produces. At the same time, the smaller step 54 of the clamping ring 52 snaps into the annular groove 56 of the protective sleeve 48.

In einem letzten Schritt wird die Schutzhülse 50 auf das Gehäuse 12 aufgeschoben, bis deren Innenverzahnung 60 in die Außenverzahnung 58 des Klemmringes 52 einrastet.In a final step, the protective sleeve 50 is pushed onto the housing 12 until its internal toothing 60 engages in the external toothing 58 of the clamping ring 52.
