Description

Die Erfindung betrifft eine elektrische Steckverbinderbuchse, welche als Radialkontaktbuchse ausgestaltet ist und mehrere Längskontaktelemente zur Kontaktierung eines korrespondierenden Steckerstiftes sowie eine die Längskontaktelemente umgebende Hülse aufweist.The invention relates to an electrical connector socket which is designed as a radial contact socket and has several longitudinal contact elements for contacting a corresponding plug pin and a sleeve surrounding the longitudinal contact elements.

Ferner betrifft die vorliegende Erfindung ein Verfahren zur Herstellung einer elektrischen Steckverbinderbuchse geformten mit mehreren Längskontaktelementen zur Kontaktierung eines korrespondierenden Steckers und mit einer die Längskontaktelemente umgebenden Buchsenhülse.Furthermore, the present invention relates to a method for producing an electrical connector socket shaped with a plurality of longitudinal contact elements for contacting a corresponding plug and with a socket sleeve surrounding the longitudinal contact elements.

In der US 2002/0187686 A1 wird eine Buchse gezeigt mit einem T-förmigen Anschluss sowie die Fertigung eines Lamellenkontaktes, bestehend aus einem Lamellenkäfig und einem gerollten Kontakthalter, die auf komplexe Art und Weise und unter Zuhilfenahme verschiedener Hilfsmittel in einer Art "Sanduhrform" verdreht werden.In the US 2002/0187686 A1 a socket is shown with a T-shaped connection and the production of a lamellar contact, consisting of a lamellar cage and a rolled contact holder, which are twisted in a complex manner and with the help of various aids in a kind of "hourglass shape".

Ebenfalls wird in der US 4,657,335 eine Buchse beschrieben, die durch eine relativ-rotatorische Bewegung der Enden eines Lamellenkäfigs in eine Hülse ausgebildet wird. Zur Festlegung des Lamellenkäfigs in der Hülse werden an den jeweiligen Enden der Hülse Ringe übergestülpt.Also in the U.S. 4,657,335 describes a bushing which is formed by a relatively rotational movement of the ends of a lamellar cage in a sleeve. To fix the lamellar cage in the sleeve, rings are slipped over the respective ends of the sleeve.

Die US 2003/0068931 A1 zeigt eine elektrische Steckverbinderbuchse umfassend eine im wesentlichen zylindrische Buchsenhülse, die an ihren stirnseitigen Enden mit Ausnehmungen versehen ist, um ein hyperbolisch gedrehten Lamellenkäfig mit seinen Anschlusszungen an bzw. in diesen Aüsnehmungen zu befestigen.The US 2003/0068931 A1 shows an electrical connector socket comprising an essentially cylindrical socket sleeve which is provided with recesses at its front ends in order to fasten a hyperbolically rotated lamellar cage with its connecting tongues on or in these recesses.

Aus der DE 10 2011 105 821 B4 ist ferner eine elektrische Steckverbinderbuchse bekannt mit einer zylindrischen Buchsenhülse, wobei die Buchsenhülse mit einem Aufnahmeraum, in dem ein hyperbolisch gedrehter Lamellenkäfig angebracht ist und die Buchsenhülse über eine erste und zweite Stirnfläche verfügt und der Lamellenkäfig mit Anschlusszungen an der ersten und zweiten Stirnfläche der Buchsenhülse mit dieser formschlüssig verbunden ist und dass in dem Übergangsbereich zwischen der Buchsenhülse und der Anschlusszunge Durchbrüche angebracht sind und dass wenigstens eine der Anschlusszungen des Lamellenkäfigs durch einen der Durchbrüche hindurchragt.From the DE 10 2011 105 821 B4 an electrical connector socket is also known with a cylindrical socket sleeve, the socket sleeve with a receiving space in which a hyperbolically rotated lamellar cage is attached and the socket sleeve has a first and second end face and the lamellar cage with connecting tongues on the first and second end face of the socket sleeve this is positively connected and that openings are made in the transition area between the socket sleeve and the connecting tongue and that at least one of the connecting tongues of the lamellar cage protrudes through one of the openings.

In der Druckschrift DE 10 2012 221 384 A1 , die als nächstliegender Stand der Technik angesehen wird, ist eine Buchsenkontaktlösung für eine Photovoltaikanwendung offenbart, bei der ebenfalls ein Kontaktlamellengitter zum Einstecken eines Gegensteckers zum Einsatz kommt.In the pamphlet DE 10 2012 221 384 A1 , which is considered to be the closest prior art, discloses a socket contact solution for a photovoltaic application in which a lamellar contact grid is also used for plugging in a mating connector.

Die im Stand der Technik bekannten Lösungen weisen allesamt den Nachteil auf, dass die Fertigung sehr aufwendig ist, insbesondere auch die geometrischen Abmessungen von Hülsen, endseitigen Hülsen und Lamellenkäfigen aufeinander abgestimmt sein müssen. Fertigungsbedingt kommt es zu einem Toleranzfeld, was erhebliche praktische Probleme aufwirft. Regelmäßig müssen Hochpräzisionsrohre eingesetzt werden, da jeweils das Innenrohr des Lamellenkäfigs in die Rohrform der umgebenen Hülse passen muss und ggf. die umgebene Hülse wiederum in eine weitere Hülsenaufnahme eingebracht werden muss und dort befestigt werden muss.The solutions known in the prior art all have the disadvantage that production is very complex, and in particular the geometric dimensions of sleeves, sleeves at the end and lamellar cages must also be coordinated with one another. Due to the manufacturing process, there is a tolerance field, which raises considerable practical problems. High-precision tubes must be used regularly, since the inner tube of the lamellar cage must fit into the tube shape of the surrounding sleeve and, if necessary, the surrounding sleeve must in turn be inserted into another sleeve receptacle and must be fastened there.

Regelmäßig besteht auch ein Problem darin, dass ein Tordieren des Lamellenkäfigs in der Hülse erfolgt, so dass zwischen der Hülse und dem Lamellenkäfig Haltevorrichtungen geschaffen werden müssen, um einerseits den Käfig drehwirksam in der Hülse festzulegen und andererseits mit einem Werkzeug in den Käfig einzugreifen, um diesen um seine Mittelachse zu tordieren, so dass sich die Kontaktlamellen im Inneren eingeschnürt werden.There is also regularly a problem that the lamellar cage is twisted in the sleeve, so that holding devices must be created between the sleeve and the lamellar cage in order to fix the cage in the sleeve so that it can rotate on the one hand and to engage the cage with a tool on the other hand to twist this around its central axis, so that the contact lamellas are constricted inside.

Ein weiteres ganz erhebliches Problem stellen solche Kontaktsysteme dar, bei der ein zylinderförmiges, insbesondere zylinderförmig gerolltes Kontaktgitter an beiden endseitigen Bundstegen in der das Kontaktgitter umgebenden Hülse, befestigt ist und somit beidseitig eingespannt wird.A further very significant problem are those contact systems in which a cylindrical, in particular cylindrical, rolled contact grid is attached to both ends of the collar webs in the sleeve surrounding the contact grid and is thus clamped on both sides.

In der Regel umfassen daher gattungsgemäße Steckverbinderbuchsen ein eingesetztes Kontaktgitter, welches mittels aufwendiger materialschlüssiger Fügeverfahren (wie z. B. Schweißen) mit der Hülse verbunden ist.As a rule, generic connector sockets therefore comprise an inserted contact grid, which is connected to the sleeve by means of complex material-locking joining processes (such as welding, for example).

Bei einem herkömmlichen und beidseitig angebundenen Kontaktgitter treten in der Anwendung eine Vielzahl von Problemen auf, da das Kontaktsystem mechanisch überbestimmt ist. Dadurch kommt es beim Steckvorgang und im späteren Betrieb durch Vibration, einwirkende Kräfte und thermomechanischen Einwirkungen zu erhöhten Belastungen an beiden Einspannstellen, da der Kontakt, insbesondere nach dem Einstecken eines korrespondierenden Stiftes, so eingespannt ist, dass er keinen der zuvor genannten Kräfte sozusagen ausweichen kann.In the case of a conventional contact grid connected on both sides, a number of problems arise in use, since the contact system is mechanically overdetermined. This results in increased loads at both clamping points during the plugging process and during later operation due to vibration, acting forces and thermomechanical effects, since the contact, especially after inserting a corresponding pin, is clamped in such a way that it cannot avoid any of the aforementioned forces, so to speak .

Aufgabe der vorliegenden Erfindung ist es daher, vorbesagte Nachteile zu überwinden und eine Steckverbinderbuchse wesentlich einfacher und wirtschaftlicher zu fertigen, wobei gleichzeitig die Anzahl der Bauteile reduziert werden soll, aber dennoch eine hohe Stromtragfähigkeit bei hoher Temperaturbelastung gewährleistet ist, insbesondere bei Temperaturen zwischen 150° und 170° und teilweise bei höheren Temperaturen sicher gewährleistet sein muss.The object of the present invention is therefore to overcome the aforementioned disadvantages and to manufacture a connector socket much more simply and economically, while at the same time reducing the number of components, but still ensuring a high current-carrying capacity at high temperature loads, in particular at temperatures between 150 ° and 170 ° and in some cases at higher temperatures must be guaranteed.

Die Erfindung wird durch eine Steckverbinderbuchse mit den Merkmalen von Anspruch 1 gelöst.The invention is achieved by a connector socket having the features of claim 1.

Die Grundidee der vorliegenden Erfindung ist es dabei, den zylinderförmigen Lamellenkäfig nicht wie im Stand der Technik bekannt an beiden Enden einzuspannen, sondern an dem einen (ersten) Ende den Lamellenkäfig zumindest axial und weiter bevorzugt auch drehfest einzuspannen und an dem anderen (zweiten) Ende eine "schwimmende Lagerung" bzw. eine axiale und drehbare Gleitlagerung vorzusehen.The basic idea of the present invention is not to clamp the cylindrical lamellar cage at both ends, as is known in the prior art, but to clamp the lamellar cage at least axially and more preferably also rotationally fixed at one (first) end and at the other (second) end to provide a "floating bearing" or an axial and rotatable sliding bearing.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass der Lamellenkäfig an seinem zweiten Ende um einen geringen Winkel α drehbar an der den Lamellenkäfig umgebenden Hülse befestigt ist.In a preferred embodiment of the invention it is provided that the lamellar cage is fastened at its second end to the sleeve surrounding the lamellar cage so that it can rotate through a small angle α.

Erfindungsgemäß ist demnach eine elektrische Steckverbinderbuchse umfassend eine zylindrische Buchsenhülse vorgesehen, wobei die Buchsenhülse mit einem Aufnahmeraum ausgebildet ist, in dem ein zylinderförmiger Lamellenkäfig mit einer Vielzahl von parallel verlaufenden Kontaktlamellen eingeschoben ist, wobei der Lamellenkäfig über einen ersten und zweiten endseitigen umlaufenden Bundsteg verfügt zwischen denen die Kontaktlamellen verlaufen, wobei der Lamellenkäfig an dem einen (ersten) Ende zumindest axial und bevorzugt auch drehfest in der Buchsenhülse eingespannt und/oder befestigt ist und an dem anderen (zweiten) gegenüberliegenden Ende eine axiale und zumindest um einen gewissen Drehwinkel drehbare Gleitlagerung gegenüber der Buchsenhülse vorgesehen ist.According to the invention, an electrical connector socket comprising a cylindrical socket sleeve is accordingly provided, the socket sleeve being designed with a receiving space in which a cylindrical lamellar cage with a plurality of parallel contact blades is inserted, the lamellar cage having a first and a second end-side circumferential flange between them the contact lamellas run, the lamellar cage being clamped and / or fastened at one (first) end at least axially and preferably also non-rotatably in the socket sleeve and at the other (second) opposite end an axial sliding bearing opposite the Socket sleeve is provided.

Erfindungsgemäß ist der Lamellenkäfig mit seinem einen Bundsteg mittels hülsenseitigen Befestigungsmittel an der Innenwand der Buchsenhülse befestigt.According to the invention, the lamellar cage is fastened with its one collar web by means of fastening means on the sleeve side on the inner wall of the socket sleeve.

In einer bevorzugten Ausführungsform ist der Lamellenkäfig mit seinem zweiten Bundsteg an der Innenwand der Buchsenhülse axialbeweglich gleitend gelagert.In a preferred embodiment, the lamellar cage is mounted with its second collar web on the inner wall of the socket sleeve so that it can slide axially.

Weiter ist erfindungsgemäß vorgesehen, dass am ersten Bundsteg zwei oder mehrere fensterartige Ausnehmungen oder Öffnungen mit je einer in Axialrichtung A betrachteten Länge L vorgesehen sind, in die an der Innenwand der Buchsenhülse jeweils vorgesehene Auswölbungen einer jeweils nahezu identischen Länge L' eingreifen, so dass dadurch eine axiale Bewegung dieses Bundsteges verhindert wird.It is further provided according to the invention that two or more window-like recesses or openings, each with a length L viewed in the axial direction A, are provided on the first flange, into which bulges of an almost identical length L 'provided on the inner wall of the socket sleeve engage, so that an axial movement of this flange is prevented.

Vorteilhaft ist weiter vorgesehen, dass am ersten Bundsteg die genannten fensterartigen Ausnehmungen mit einer quer zur Axialrichtung betrachteten Breite B vorgesehen sind, in die die an der Innenwand der Buchsenhülse vorgesehenen genannten Auswölbungen einer gleichen oder einer geringeren Breite B' eingreifen. Hierdurch wird die Montage erleichtert und wird weiter gewährleistet, dass eine gewisse Drehlagerung des Bundsteges gegenüber der Buchsenhülse gegeben ist, wobei das Ausmaß der Drehung davon abhängt, je nachdem wie groß die Breitendifferenzen zwischen der Breite B und der Breite B' gewählt wurden. Bevorzugt wird ein Drehwinkelabstand von 2° bis 4° gewählt, so dass ein guter Halt einerseits und eine einfachere Montage andererseits gewährleistet sind.Advantageously, it is further provided that the mentioned window-like recesses with a width B viewed transversely to the axial direction are provided on the first collar web, in which the mentioned bulges provided on the inner wall of the socket sleeve engage with the same or a smaller width B '. This facilitates assembly and further ensures that there is a certain rotational bearing of the flange with respect to the socket sleeve, the extent of the rotation depending on how great the width differences between the width B and the width B 'have been selected. A rotation angle distance of 2 ° to 4 ° is preferably selected, so that a good hold on the one hand and easier assembly on the other hand are guaranteed.

Erfindungsgemäß sind die Befestigungsmittel an der Buchsenhülse als Prägungen im Mantel der Buchsenhülse vorgesehen, wobei am Außenmantel der Buchsenhülse Vertiefungen und am Innenmantel der Buchsenhülse hervorstehende Auswölbungen ausgebildet sind. Die Positionen der Auswölbungen werden korrespondierend auf die Positionen der fensterartigen Öffnungen abgestimmt.According to the invention, the fastening means on the socket sleeve are provided as embossings in the jacket of the socket sleeve, with depressions being formed on the outer jacket of the socket sleeve and protruding bulges on the inner jacket of the socket sleeve. The positions of the bulges are matched to correspond to the positions of the window-like openings.

Weiter bevorzugt ist es, wenn die Befestigungsmittel als im Wesentlichen quaderförmige Aufwölbungen mit jeweils zwei gegenüberliegenden Längsseitenkanten und jeweils zwei gegenüberliegenden Querseitenkanten ausgebildet sind, so dass definierte Anschläge und Begrenzungskanten zum Lagern des einen Bundstegs vorhanden sind und die fensterartigen Ausnehmungen mit einer dazu korrespondierenden Form ausgebildet werden können.It is further preferred if the fastening means are designed as essentially cuboid bulges each with two opposing longitudinal side edges and two opposing transverse side edges, so that defined stops and delimiting edges are provided for mounting the one flange and the window-like recesses are designed with a corresponding shape can.

In einer vorteilhaften Ausgestaltung des Lamellenkäfigs, kann dieser in seinem zentralen mittigen Abschnitt in Axialrichtung betrachten einen geringeren Durchmesser aufweisen, als der Durchmesser an den Bundestegen.In an advantageous embodiment of the lamellar cage, it can have a smaller diameter in its central, central section, viewed in the axial direction, than the diameter at the collar webs.

Ein weiterer Aspekt der vorliegenden Offenbarung, der nicht beansprucht wird, betrifft ein Verfahren zur Herstellung einer wie zuvor beschriebenen elektrischen Steckverbinderbuchse mit den folgenden Verfahrensschritten:

  1. a. Herstellen eines Kontaktlamellengitters mit zwei endseitigen Bundstegen mit einer Vielzahl von dazwischen verlaufenden parallelen Kontaktlamellen;
  2. b. Einbringen von zwei oder mehreren fensterartigen Öffnungen (an ausgewählten Positionen) in den einen Bundsteg des Kontaktlamellengitters und Überführen des Kontaktlamellengitters in eine zylindrische Form,
  3. c. Bereitstellen einer passend geformten Buchsenhülse mit einem Aufnahmeraum zur Aufnahme des zylindrischen Kontaktlamellengitters und Anbringen von in den Aufnahmeraum hervorstehende Auswölbungen (korrespondierend zu den Positionen der Öffnungen in Schritt b) an dem Innenmantel der Buchsenhülse, vorzugsweise durch Prägen und
  4. d. Einbringen des zylindrischen Kontaktlamellengitters in den Aufnahmeraum derart, dass die Auswölbungen in die fensterartigen Öffnungen eingreifen und den einen Bundsteg festlegen.
Another aspect of the present disclosure, which is not claimed, relates to a method for producing an electrical connector socket as described above with the following method steps:
  1. a. Production of a contact lamella grid with two end-side collar webs with a plurality of parallel contact lamellae running between them;
  2. b. Introducing two or more window-like openings (at selected positions) in one of the flange webs of the contact lamella grid and converting the contact lamella grid into a cylindrical shape,
  3. c. Providing a suitably shaped socket sleeve with a receiving space for receiving the cylindrical contact lamellar grid and attaching bulges protruding into the receiving space (corresponding to the positions of the openings in step b) on the inner jacket of the socket sleeve, preferably by embossing and
  4. d. Introducing the cylindrical contact lamella grid into the receiving space in such a way that the bulges engage in the window-like openings and define the one flange web.

Bevorzugt ist es, wenn dabei die Länge L der jeweiligen Öffnungen auf die Länge L' der jeweiligen Auswölbungen so abgestimmt wird, dass der eine Bundsteg in Axialrichtung nicht bewegbar ist.It is preferred if the length L of the respective openings is matched to the length L 'of the respective bulges in such a way that the one collar web cannot be moved in the axial direction.

Die Ausgestaltungen der Erfindung ergeben sich aus den Patentansprüchen sowie den Figuren und der dazugehörigen Figurenbeschreibung, wobei die Figuren der Zeichnungen folgendes darstellen:
Im Folgenden wird die Erfindung anhand des folgenden Ausführungsbeispiels, das in den Fig. 1 und 2 dargestellt ist, näher erläutert. Gleiche Bezugszeichen weisen dabei auf gleiche funktionelle oder strukturelle Merkmale hin.The embodiments of the invention result from the patent claims as well as the figures and the associated description of the figures, the figures of the drawings representing the following:
In the following, the invention is based on the following embodiment, which is shown in Figs. 1 and 2 is shown, explained in more detail. The same reference symbols indicate the same functional or structural features.

Dargestellt ist eine halboffene Schnittansicht einer elektrische Steckverbinderbuchse 1 umfassend eine zylindrische Buchsenhülse 2, wobei die Buchsenhülse 2 mit einem Aufnahmeraum 20 ausgebildet ist, in dem ein zylinderförmiger Lamellenkäfig 3 mit einer Vielzahl von parallel verlaufenden Kontaktlamellen 31 eingebracht ist.A half-open sectional view of an electrical connector socket 1 comprising a cylindrical socket sleeve 2 is shown, the socket sleeve 2 being formed with a receiving space 20 in which a cylindrical lamellar cage 3 with a plurality of parallel contact blades 31 is introduced.

Die zylinderförmige und rohrförmige Buchsenhülse 2 weist einen umfangsgeschlossenen Mantel 7 auf und ist an beiden Enden offen.The cylindrical and tubular socket sleeve 2 has a circumferentially closed jacket 7 and is open at both ends.

Der Lamellenkäfig 3 verfügt über einen ersten und zweiten endseitigen umlaufenden Bundsteg 32a, 32b zwischen denen eine Vielzahl von Kontaktlamellen 31 verlaufen. Die Kontaktlamellen 31 verlaufen im Wesentlichen parallel zueinander unter Bildung eines Spaltes zwischen je zwei benachbarten Kontaktlamellen 31.The lamellar cage 3 has a first and second circumferential collar web 32a, 32b at the end, between which a multiplicity of contact lamellas 31 run. The contact lamellae 31 run essentially parallel to one another, forming a gap between each two adjacent contact lamellae 31.

Der Lamellenkäfig 3 ist an dem einen (ersten) Ende zumindest axial und bevorzugt auch drehfest in der Buchsenhülse 2 eingespannt und befestigt und es ist an dem anderen (zweiten) gegenüberliegenden Ende des Lamellenkäfigs 3 eine axiale und drehbare Gleitlagerung gegenüber der Buchsenhülse 2 vorgesehen ist.The lamellar cage 3 is clamped and fastened at one (first) end at least axially and preferably also non-rotatably in the socket sleeve 2 and an axial and rotatable sliding bearing is provided opposite the socket sleeve 2 at the other (second) opposite end of the lamellar cage 3.

Wie in der Fig. 1 und 2 ferner ersichtlich ist der Lamellenkäfig 3 mit seinem einen Bundsteg 32a mittels Befestigungsmittel 25 an der Innenwand 23 der Buchsenhülse 2 befestigt. Hierzu sind in Umfangsrichtung drei Befestigungsmittel 25 vorgesehen.Like in the Figs. 1 and 2 Furthermore, the lamellar cage 3 is fastened with its one collar web 32a by means of fastening means 25 on the inner wall 23 of the socket sleeve 2. For this purpose, three fastening means 25 are provided in the circumferential direction.

Ferner ist der Lamellenkäfig 3 mit seinem zweiten Bundsteg 32b an der Innenwand 23 der Buchsenhülse 2 axialbeweglich gleitend gelagert und daher bestimmungsgemäß nicht eingespannt. Beim Steckvorgang mit einem nicht dargestellten Steckpin werden die Kontaktlamellen 31 in radialer Richtung verformt, da der Lamellenkäfig 3 in seinem mittigen zentralen Abschnitt eine Einschnürung aufweist und demnach einen geringeren Durchmesser aufweist. Der Kontaktpin weist hierzu einen größeren Durchmesser auf als der Lamellenkäfig 3 in seinem mittigen zentralen Abschnitt. Die einseitige Gleitlagerung des Bundstegs 32b erlaubt eine axiale Bewegung desselben. Da die Auslenkung reversibel ist, kehrt der Lamellenkäfig 3 in seine ursprüngliche Form zurück, sobald der Kontaktpin wieder entfernt wurde. Die gleiche Relativbewegung wird bei Erschütterungen, beim thermomechanischen Erhitzen etc. ermöglicht, so dass plastische Verformungen und Schwächungen des Kontaktsystems vermieden werden.Furthermore, the lamellar cage 3 with its second collar web 32b is mounted on the inner wall 23 of the socket sleeve 2 so that it can slide axially and is therefore not clamped as intended. During the plugging process with a plug pin, not shown, the contact lamellae 31 are deformed in the radial direction, since the lamellae cage 3 has a constriction in its central section and accordingly has a smaller diameter. For this purpose, the contact pin has a larger diameter than the lamellar cage 3 in its central central section. The one-sided sliding bearing of the collar web 32b allows it to move axially. Since the deflection is reversible, the lamellar cage 3 returns to its original shape as soon as the contact pin has been removed again. The same relative movement is made possible in the event of vibrations, thermomechanical heating, etc., so that plastic deformation and weakening of the contact system are avoided.

Am ersten Bundsteg 32a sind drei fensterartige Ausnehmungen bzw. Öffnungen 35 vorgesehen, wovon eine in den Ansichten der Figur 1 und 2 erkennbar ist. Die Öffnungen sind je mit einer in Axialrichtung A betrachteten Länge L vorgesehen, in die, die an der Innenwand 23 der Buchsenhülse 2 jeweils vorgesehene Auswölbungen 25 einer jeweils nahezu identischen Länge L' eingreifen, so dass dadurch eine axiale Bewegung dieses Bundsteges 32a verhindert wird.On the first collar web 32a, three window-like recesses or openings 35 are provided, one of which is shown in the views of FIG Figures 1 and 2 is recognizable. The openings are each provided with a length L viewed in the axial direction A, into which the bulges 25 provided on the inner wall 23 of the socket sleeve 2, each of a nearly identical length L ', engage, so that an axial movement of this collar web 32a is prevented.

Die am ersten Bundsteg 32a fensterartigen Ausnehmungen 35 sind ferner mit einer quer zur Axialrichtung A betrachteten Breite B ausgebildet, in die die Auswölbungen 25 einer geringeren Breite B' eingreifen.The window-like recesses 35 on the first collar web 32a are also formed with a width B viewed transversely to the axial direction A, into which the bulges 25 of a smaller width B 'engage.

Am Außenmantel 24 der Buchsenhülse 2 sind ferner Vertiefungen 26 und gegenüberliegend zu den hervorstehende Auswölbungen 25 im Mantel 7 ausgebildet.On the outer jacket 24 of the socket sleeve 2, depressions 26 and opposite to the protruding bulges 25 in the jacket 7 are also formed.
