Description

Die Erfindung betrifft ein Anschlußstück eines Filterbeutels für Staubsauger, mit einem feststehenden, im wesentlichen plattenförmigen Grundkörper, der eine dem Beutel zugewandte innere Materiallage und eine dem Beutel abgewandte äußere Materiallage, diese Materiallagen insbesondere aus Kartonmaterial, aufweist, die übereinander angeordnet und beiderseits eines zwischen ihnen vorhandenen, endseitig offenen Führungsschlitzes miteinander verbunden sind, in dem ein aus dem Grundkörper ragender Verschlußschieber geführt ist, wobei der Grundkörper eine von fluchtenden Lochungen der Materiallagen gebildete Anschlußöffnung und der Verschlußschieber eine Durchgangsöffnung aufweist und der Verschlußschieber aus einer die Anschlußöffnung freigebenden Offenstellung, in der seine Durchgangsöffnung fluchtend zur Anschlußöffnung angeordnet ist, in eine die Anschlußöffnung verschließende Schließstellung bewegbar ist und wobei der Grundkörper an seiner dem Beutel abgewandten Außenseite eine um die Anschlußöffnung umlaufende Anlagefläche bildet, die im in den Staubsauger eingesetzten Zustand an einem Dichtkörper des Staubsaugers anliegt. The invention relates to a connector of a filter bag for vacuum cleaners, with a fixed, essentially plate-shaped Basic body, the inner one facing the bag Material layer and an outer material layer facing away from the bag, has these layers of material, in particular of cardboard material, which are arranged one above the other and on both sides one between their existing, open end guide slot are connected to one another in which a protruding from the base body Locking slide is guided, the base body a connection opening formed by aligned perforations in the material layers and the slide valve has a through opening has and the slide valve from a connection opening releasing open position, in its through opening is aligned with the connection opening, in a connection opening closing position is movable and the base body on its outside facing away from the bag forms a contact surface surrounding the connection opening, the one in the state in the vacuum cleaner Sealing body of the vacuum cleaner rests.

Sowohl bei Haushaltsstaubsaugern als auch bei größeren, gewerblich eingesetzten Staubsaugern werden zum Sammeln des anfallenden Staubes Filterbeutel - hierunter sind auch größere Filtersäcke oder dergleichen zu verstehen - verwendet. Dabei wird mittels eines Staubsaugergebläses ein Saugstrom erzeugt, der den Staub in einen Saugkanal, Saugschlauch oder dergleichen zieht und von dort durch die Staubeintrittsöffnung in den betreffenden Filterbeutel fördert. Der in der angesaugten Luft enthaltene Staub wird von der Filterbeutelwand zurückgehalten, während der vom Staub befreite Luftstrom die Filterbeutelwand durchdringt und anschließend in die Umgebung ausgeblasen wird. Ist der Filtersack voll, wird er entnommen und kann weggeworfen werden.Both for household vacuum cleaners and for larger, commercial ones Vacuum cleaners are used to collect the accumulated Dusty filter bags - including larger filter bags or to understand - used. Doing so generates a suction flow by means of a vacuum cleaner fan, which the dust into a suction channel, suction hose or the like pulls and from there through the dust inlet opening in the concerned Filter bag promotes. The one in the sucked air dust contained is retained by the filter bag wall, during the dust-free air flow the filter bag wall penetrated and then blown into the environment. If the filter bag is full, it is removed and can be thrown away become.

Ein Auschlußstück der eingangs genannten Art ist aus der EP-A-0 623 305 bekannt. Dabei erfolgt das Festlegen des Filterbeutels am Staubsauger mittels des am Filterbeutel im Bereich von dessen Eintrittsöffnung befestigten Anschlußstücks, das so angebracht ist, daß sich die von seinem Grundkörper gebildete Anschlußöffnung mit der Eintrittsöffnung des eigentlichen Filterbeutels deckt, so daß die Staubluft eingeleitet werden kann. Mit Hilfe des Verschlußschiebers kann dann die genannte Anschlußöffnung und somit auch die Eintrittsöffnung des Filterbeutels verschlossen werden, wenn der Filterbeutel vom Staubsauger weggenommen wird. Auf diese Weise kann aus dem weggenommenen Filterbeutel kein Staub in die Umgebung entweichen. A exclusion piece of the type mentioned is from the EP-A-0 623 305 known. This is done Fix the filter bag on the vacuum cleaner using the attached to the filter bag in the area of its inlet opening Connector that is attached so that the from its base body formed connection opening with the inlet opening of the actual filter bag, so that the Dust air can be introduced. With the help of the slide can then the mentioned connection opening and thus also the inlet opening of the filter bag is closed, when the filter bag is removed from the vacuum cleaner. On this way no dust can be removed from the removed filter bag escape into the environment.

Auch im in den Staubsauger eingesetzten Zustand soll ein Staubaustritt in den den Filterbeutel aufnehmenden Raum des Staubsaugers vermieden werden. Hierzu dient bei bekannten Anschlußstücken der eingangs genannten Art der staubsaugerseitige Dichtkörper, der so angeordnet ist, daß er außen am Anschlußstück um die Anschlußöffnung herum anliegt, so daß sich eine ringförmige Abdichtung des Staubwegs an dieser Stelle ergibt.Dust should also escape when inserted in the vacuum cleaner into the space of the vacuum cleaner that holds the filter bag be avoided. This is used in known connectors of the type mentioned at the beginning of the vacuum cleaner side Sealing body, which is arranged so that it is on the outside of the connector bears around the connection opening, so that there is a ring-shaped sealing of the dust path results at this point.

Der den Verschlußschieber aufnehmende Führungsschlitz des Anschlußstücks ist jedoch an seinen der Bewegungsrichtung des Verschlußschiebers entsprechenden Enden offen, da der Verschlußschieber hier aus dem Grundkörper ragt, damit er mit der Hand ergriffen werden kann. Es handelt sich zwar um einen sehr flachen, im wesentlichen der Materialdicke des Verschlußschiebers entsprechenden Führungsschlitz. Trotzdem können Staubpartikel, insbesondere wenn es sich um einen feinen Staub handelt, über die offenen Führungsschlitzenden nach außen gelangen und den Filterbeutel-Aufnahmeraum des Staubsaugers verschmutzen.The guide slot of the connector receiving the slide is however at its the direction of movement of the Slider corresponding ends open because of the slider protrudes from the base here so that it Hand can be taken. Although it is a very flat, essentially the material thickness of the slide gate corresponding guide slot. Nevertheless, dust particles, especially if the dust is fine, get out through the open guide slot ends and contaminate the filter bag receiving area of the vacuum cleaner.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Anschlußstück der eingangs genannten Art zu schaffen, bei dem die Dichtheit gegen einen Staubaustritt verbessert wird. Dies soll mit möglichst einfachen Mitteln erreicht werden, was insbesondere auch im Hinblick darauf von großer Bedeutung ist, daß es sich hier um einen Massenartikel handelt.The present invention is therefore based on the object to create a connector of the type mentioned at which improves the tightness against dust leakage. This should be achieved with the simplest possible means, what is particularly important with regard to this, that this is a mass article.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Anschlußöffnung ein von der inneren Materiallage ausgehender, in oder durch die Lochung der äußeren Materiallage ragender Anlagering angeordnet ist, der die Anlagefläche bildet oder ein die Anlagefläche bildendes Dichtteil in Stellung hält, wobei der Grundkörper mit dem Anlagering und/oder der Verschlußschieber so flexibel sind, daß der Verschlußschieber über den Anlagering hinweg in seine Schließstellung bewegbar ist.This object is achieved in that the Connection opening of a starting from the inner material layer bearing ring protruding in or through the perforation of the outer material layer is arranged, which forms the contact surface or a holds the sealing surface forming part in position, whereby the base body with the contact ring and / or the locking slide are so flexible that the locking slide over the bearing ring is movable away into its closed position.

Dieser Anlagering bzw. das von ihm in Stellung gehaltene Dichtteil dichtet also zum einen stirnseitig gegen den staubsaugerseitigen Dichtkörper und zum anderen umfangsseitig rundum den Führungsschlitz des Verschlußschiebers ab, so daß auch über den Führungsschlitz kein Staub in den Staubsauger gelangen kann.This contact ring or the sealing part held by it in position seals on the one hand against the vacuum cleaner side Sealing body and the other around the circumference Guide slot of the slide gate, so that also on the Guide slot no dust can get into the vacuum cleaner.

Zweckmäßigerweise ist der Anlagering einstückig mit der inneren Materiallage des Grundkörpers verbunden, indem die Lochung der inneren Materiallage einen kleineren Durchmesser als die Lochung der äußeren Materiallage aufweist, so daß ein nach radial innen über den Lochrand der Lochung der äußeren Materiallage vorstehender Ringbereich der inneren Materiallage gebildet wird, der zum in oder durch die Lochung der äußeren Materiallage ragenden Anlagering geformt ist. Dies ist eine konstruktiv und kostenmäßig sehr einfache Lösung. Dabei kann der den Anlagering bildende Ringbereich der inneren Materiallage am Lochrand der äußeren Materiallage gedrückt sein. Auf diese Weise kann bei der Herstellung der Lochrand der äußeren Materiallage sozusagen als formgebendes Teil beim Eindrücken des Anlagerings verwendet werden. The bearing ring is expediently in one piece with the inner ring Material layer of the base body connected by the perforation of the inner material layer a smaller diameter than the perforation the outer layer of material, so that a radial inside over the perforated edge of the perforation of the outer material layer protruding ring area of the inner material layer is formed becomes that in or through the perforation of the outer material layer projecting bearing ring is shaped. This is constructive and very simple solution in terms of cost. The ring can forming ring area of the inner material layer at the edge of the hole the outer layer of material. In this way can in the manufacture of the hole edge of the outer layer of material so to speak as a shaping part when pressing the bearing ring be used.

Liegt der Anlagering bei in den Staubsauger eingesetztem Filterbeutel nicht unmittelbar sondern über ein von ihm in Stellung gehaltenes Dichtteil am staubsaugerseitigen Dichtkörper an, kann das Dichtteil eine gelochte Dichtmembran sein, die zwischen den beiden Materiallagen des Grundkörpers festgelegt ist.Is the bearing ring with the filter bag inserted in the vacuum cleaner not immediately but via one of them in position sealing part held on the vacuum cleaner-side sealing body the sealing part can be a perforated sealing membrane which between the two material layers of the base body is.

Between the two material layers 7, 8 are not connected to the two areas 12, 13, so that the slide 6 is added and in Longitudinal direction L can be moved.

Der Verschlußschieber 6 enthält eine der Anschlußöffnung 4 des Grundkörpers 5 zugeordnete Durchgangsöffnung 14. In seiner Ausgangsstellung, die er beim Einsetzen des Anschlußstücks 1 in den Staubsauger einnimmt, befindet sich der Verschlußschieber 6 in seiner Offenstellung (Figur 1), in der seine Durchgangsöffnung 14 an der Stelle der Anschlußöffnung 4 des Grundkörpers angeordnet ist, so daß diese und somit auch die Eintrittsöffnung 3 des Filterbeutels frei ist. Aus dieser Offenstellung kann der Verschlußschieber 6 in eine Schließstellung (Figur 2) bewegt werden, in der er die Anschlußöffnung 4 verschließt. Dieses Bewegen erfolgt beim Ausführungsbeispiel durch Ziehen des Verschlußschiebers 6 in Längsrichtung L.The slide valve 6 contains one of the connection opening 4 of the Main body 5 assigned through opening 14. In its initial position, which he when inserting the connector 1 in occupies the vacuum cleaner, there is the slide 6 in its open position (Figure 1), in the through opening 14 at the location of the connection opening 4 of the base body is arranged so that this and thus also the inlet opening 3 of the filter bag is free. From this open position can the slide 6 in a closed position (Figure 2) are moved in which it closes the connection opening 4. In the exemplary embodiment, this movement is carried out by pulling of the slide 6 in the longitudinal direction L.

Der Verschlußschieber 6 weist in seiner beim Ausführungsbeispiel mit der Längsrichtung L zusammenfallenden Bewegungsrichtung einerseits der Durchgangsöffnung 14 einen Verschlußbereich 15 und andererseits der Durchgangsöffnung 14 einen außerhalb des Grundkörpers 5 angeordneten Handgriff 16 auf, der mit der Hand ergriffen werden kann. Zieht man in Figur 1 am Handgriff 16 nach links, gelangt der Verschlußbereich 15 an die Stelle der Anschlußöffnung 4 des Grundkörpers und verschließt diese. Der Verschlußschieber 6 kann, muß jedoch nicht unbedingt, auch mit seinem Verschlußbereich 15 aus dem Grundkörper 5 ragen, und zwar an der dem Handgriff 16 entgegengesetzten Grundkörperseite.The slide valve 6 has in its in the embodiment direction of movement coinciding with the longitudinal direction L. on the one hand the through opening 14 has a closure area 15 and on the other hand the through opening 14 one outside of the base body 5 arranged handle 16, which with the Hand can be taken. You pull the handle in Figure 1 16 to the left, the closure area 15 comes into place the connection opening 4 of the base body and closes it. The slide 6 can, but not necessarily, also protrude with its closure region 15 from the base body 5, and on the side of the body opposite the handle 16.

In der Querschnittsdarstellung gemäß den Figuren 3 und 4 sind vom Verschlußschieber 6 nur die beiden beiderseits der Durchgangsöffnung 14 liegenden, stegartigen Verschlußschieberbereiche 17, 18 sichtbar.3 and 4 are in the cross-sectional illustration from the slide 6 only the two on both sides of the through opening 14 horizontal, web-like locking slide areas 17, 18 visible.

Damit der Verschlußschieber 6 beim Überführen in die Schließstellung nicht ganz aus dem Grundkörper 5 herausgezogen werden kann, läuft er gegen einen am Grundkörper 5 vorhandenen Anschlag. Beim Ausführungsbeispiel sind hierzu an der äußeren Materiallage 8 im Bereich der Durchgangsöffnung 14 des Verschlußschiebers 6 zwei Stanzzugen 19, 20 vorhanden, die durch die Durchgangsöffnung 14 des Verschlußschiebers 6 hindurch zur inneren Materiallage 7 hin abgebogen sind und dort jeweils in eine entsprechend angebrachte Ausnehmung eingreifen. Diese Stanzzungen 19, 20 durchqueren also den Führungsschlitz 11 für den Verschlußschieber 6. In der Schließstellung gemäß Figur 2 gelangt der betreffende Rand der Durchgangsöffnung 14 zur Anlage an diese Stanzzungen 19, 20 bzw. gleitet auf diese auf. So that the slide 6 when moving into the closed position cannot be completely pulled out of the base body 5 can, it runs against an existing stop on the base body 5. In the exemplary embodiment, this is on the outer material layer 8 in the area of the through opening 14 of the slide gate 6 two punching dies 19, 20 are present, which by the Through opening 14 of the slide 6 through to the inner Material layer 7 are bent and there in each engage a corresponding recess. This Punching tongues 19, 20 thus pass through the guide slot 11 for the locking slide 6. In the closed position according to FIG. 2 the relevant edge of the passage opening 14 comes to rest to these punch tongues 19, 20 or slide on them.

Wie bereits erwähnt, sind die beiden Grundkörper-Materiallagen 7, 8 breiter als der Verschlußschieber 6 und beiderseits von diesem an den Seitenbereichen 12, 13 über die Grundkörperlänge hinweg miteinander verklebt. Um die Reibung zwischen den Grundkörper-Materiallagen 7, 8 und dem Verschlußschieber 6 zu verringern, kann der den Verschlußschieber führende Bereich mindestens einer der Materiallagen mittels beidseitig vom Verschlußschieber angebrachten Prägelinien 21, 22 etwas abgesetzt, d. h. von der jeweils anderen Materiallage etwas entfernt sein. Das Verschiebespiel für den Verschlußschieber könnte man jedoch auch auf andere Weise erreichen. Dies ist im vorliegenden Zusammenhang jedoch nicht weiter von Interesse.As already mentioned, the two basic material layers are 7, 8 wider than the slide 6 and on both sides of this on the side areas 12, 13 over the base body length glued together. About the friction between the base material layers 7, 8 and to reduce the slide 6 the area leading the slide can at least one of the material layers by means of the slide slide on both sides attached embossing lines 21, 22 somewhat offset, d. H. be somewhat distant from the other material layer. The Sliding game for the slide gate could be reach in other ways. This is in the present context but of no further interest.

Der Führungsschlitz 11 ist an seinen beiden Enden 23, 24 offen, d. h. die beiden Materiallagen 7, 8 sind hier nicht aufeinander geklebt, damit der Verschlußschieber 6 austreten kann. Gegebenenfalls, wenn der Verschlußschieber mit seinem dem Handgriff entgegengesetzten Ende nicht aus dem Grundkörper ragen sollte, könnte man den Führungsschlitz an dem betreffenden Ende ebenfalls verschließen. In jedem Falle ist der Führungsschlitz aber zumindest am dem Handgriff 16 zugewandeten Ende offen.The guide slot 11 is open at both ends 23, 24, d. H. the two layers of material 7, 8 are not on top of each other here glued so that the slide 6 can emerge. Possibly, when the slide gate with its handle opposite end should not protrude from the main body, you could also use the guide slot at that end close. In any case, the guide slot is open at least at the end facing the handle 16.

An den Führungsschlitzenden 23, 24 ist also das Filterbeutelinnere nicht staubdicht abgeschlossen, so daß hier bei in den Staubsauger eingesetztem Filterbeutel, wenn sich der Verschlußschieber in seiner Offenstellung befindet, ohne die nachstehend erläuterten Maßnahmen angesaugte Staubpartikel am Verschlußschieber vorbei in den den Filterbeutel aufnehmenden Raum des Staubsaugers gelangen und ihn verschmutzen können.At the guide slot ends 23, 24 is the inside of the filter bag not finished dustproof, so that here in the Vacuum cleaner inserted filter bag when the slide gate is in its open position without the following measures explained dust particles sucked in on the slide over into the filter bag 's room Vacuum cleaner and get dirty.

In diesem Zusammenhang ist zunächst von Bedeutung, daß der Staubsauger, für den der dargestellte Filterbeutel gedacht ist, einen feststehenden Dichtkörper auf weist, dem eine an der Aussenseite des Grundkörpers 5 des Anschlußstücks 1 um die Anschlußöffnung 4 umlaufende Anlagefläche zugeordnet ist, die im in den Staubsauger eingesetzten Zustand an der zugewandten Dichtfläche 25 des am Staubsauger angeordneten Dichtkörpers anliegt, so daß hier eine um die Anschlußöffnung 4 umlaufende Ringdichtung gebildet wird. Beim Einsetzen des Filterbeutels in den Staubsauger wird das Anschlußstück 1 mit seiner Anschlußöffnung 4 auf einen staubsaugerseitigen Anschlußstutzen aufgesteckt, wobei die Grundkörper-Außenseite an der Dichtfläche 25 zur Anlage gelangt.In this context it is important that the Vacuum cleaner for which the filter bag shown is intended, has a fixed sealing body, one on the outside of the base body 5 of the connector 1 around the connection opening 4 circumferential contact surface is assigned, which in inserted in the vacuum cleaner state on the facing Sealing surface 25 of the sealing body arranged on the vacuum cleaner rests, so that here one around the connection opening 4 Ring seal is formed. When inserting the filter bag in the vacuum cleaner becomes the connector 1 with its connection opening 4 plugged onto a connection piece on the vacuum cleaner side, the base body outside on the sealing surface 25 comes to the plant.

Um nun einen endseitigen Staubaustritt an den Führungsschlitzenden zu vermeiden, ist an der Anschlußöffnung 4 des Anschlußstücks 1 an diesem ein von der inneren Materiallage 7 ausgehender, in oder durch die Lochung 10 der äußeren Materiallage 8 ragender Anlagering 26 angeordnet, der die sich gegen die geräteseitige Dichtfläche 25 legende Anlagefläche 27 bildet (Ausführungsbeispiel nach den Figuren 1 bis 3) oder ein die Anlagefläche 27a bildendes Dichtteil 28 in Stellung hält (Ausführungsbeispiel nach Figur 4). Der Anlagering 26 durchgreift also in der Offenstellung des Verschlußschiebers 6 dessen Durchgangsöffnung 14 und ragt bis zur dem Filterbeutel abgewandten Außenseite des Anschlußstücks 1 vor, so daß die Anschlußöffnung 4 über ihre axiale Länge und somit auch über den Führungsschlitz 11 hinweg umlaufend vom Anlagering 26 begrenzt wird, der somit eine den Eintritt von Staubpartikel in den Führungsschlitz 11 verhindernde Abdichtung bildet.Now around an end-side dust outlet at the guide slot ends To avoid, is at the connection opening 4 of the connector 1 on this one, starting from the inner layer of material 7, in or through the perforation 10 of the outer material layer 8 projecting abutment ring 26 which is against the device side Sealing surface 25 forming contact surface 27 forms (embodiment according to Figures 1 to 3) or the contact surface 27a forming sealing part 28 holds in position (embodiment according to Figure 4). The bearing ring 26 thus penetrates in the open position of the slide 6, its through opening 14 and extends to the side facing away from the filter bag Outside of the connector 1 in front, so that the connection opening 4 over its axial length and thus also over the guide slot 11 is delimited all around by the bearing ring 26, which prevents dust particles from entering the guide slot 11 forms a preventive seal.

Der etwa in der Ebene der von der äußeren Materiallage 8 gebildeten Anschlußstück-Außenseite liegende Bereich des Anlagerings 26 bildet also die Anlagefläche, die im in den Staubsauger eingesetzten Zustand an der geräteseitigen Dichtfläche 25 anliegt bzw. das Dichtteil 28 gegen die Dichtfläche 25 hält, so daß auch hier eine staubdichte Anordnung vorliegt. Der die Dichtfläche 25 bildende Dichtkörper kann aus elastischem Dichtmaterial sein.That roughly in the plane of that formed by the outer layer of material 8 Area of the contact ring on the outside of the connector 26 thus forms the contact surface that is used in the vacuum cleaner Condition on the device-side sealing surface 25 is present or the sealing part 28 holds against the sealing surface 25, so that here too there is a dustproof arrangement. The the sealing surface 25 sealing body can be made of elastic sealing material his.

Beim Überführen des Verschlußschiebers 6 aus seiner Offenstellung in die Schließstellung muß sich der Verschlußbereich 15 des Verschlußschiebers 6 über die Anschlußöffnung 4 legen. Hierzu ist der Grundkörper 5 mit dem Anlagering 26 und/oder der Verschlußschieber 6 so flexibel gestaltet, daß der Verschlußschieber 6 über den Anlagering 26 hinweg in seine Schließstellung bewegt werden kann. Der Verschlußschieber lenkt dabei aus seiner ansonsten eingenommenen Ebene der axialen Abmessung des Anlagerings 26 entsprechend aus.When transferring the slide 6 from its open position in the closed position, the locking area 15 place the slide 6 over the connection opening 4. For this purpose, the base body 5 with the contact ring 26 and / or the Locking slide 6 designed so flexible that the locking slide 6 over the bearing ring 26 in its closed position can be moved. The slide gate deflects its otherwise occupied level of the axial dimension of the Bearing rings 26 accordingly.

Der Anlagering 26 bildet also sozusagen einen Ringsitz, der durch die äußere Materiallage 8 hindurch reicht und als Dichtsitz für die geräteseitige Dichtfläche 25 wirkt. The bearing ring 26 thus forms a ring seat, so to speak extends through the outer layer of material 8 and as a sealing seat acts on the device-side sealing surface 25.

Das bei dem Ausführungsbeispiel nach Figur 4 vorhandene Dichtteil 28 wird von einer an der Stelle der Anschlußöffnung 4 gelochten Dichtmembran 29 gebildet, die zwischen den beiden Materiallagen 7, 8 des Grundkörpers 5 festgelegt, zweckmäßigerweise an die Innenseite der äußeren Materiallage 8 geklebt ist. Diese Dichtmembran 29 steht ringartig in die Lochung 10 der äußeren Materiallage 8 vor und überdeckt den Anlagering 26. Die Dichtmembran 29 besteht aus elastischem Dichtmaterial.The sealing part present in the exemplary embodiment according to FIG. 4 28 is perforated at the location of the connection opening 4 Sealing membrane 29 formed between the two layers of material 7, 8 of the base body 5 fixed, expediently is glued to the inside of the outer layer of material 8. This Sealing membrane 29 is ring-like in the perforation 10 of the outer Material layer 8 in front and covers the contact ring 26. The sealing membrane 29 consists of elastic sealing material.

Der Anlagering 26 ist zweckmäßigerweise einstückig mit der inneren Materiallage 7 des Grundkörpers 5 verbunden. In diesem Zusammenhang weist die Lochung 9 der inneren Materiallage 7 einen kleineren Durchmesser als die Lochung 10 der äußeren Materiallage 8 auf, so daß ein nach radial innen über den Lochrand 30 der äußeren Materiallage 8 vorstehender Ringbereich der inneren Materiallage 7 gebildet wird, der zum in oder durch die Lochung 10 der äußeren Materiallage ragenden Anlagering 26 geformt ist. Der Anlagering 26 ist also sozusagen aus der sonstigen Ebene der inneren Materiallage 7 etwas ausgestülpt oder dergleichen. Dabei kann der den Anlagering 26 bildende Ringbereich der inneren Materiallage 7 am Lochrand 30 der äußeren Materiallage 8 in die Lochung 10 der äußeren Materiallage 8 gedrückt sein. Bei der Herstellung kann also so vorgegangen werden, daß man bei ansonsten fertigem Anschlußstück den Lochrand 30 der äußeren Materiallage 8 sozusagen als Form nimmt, in die man den den Anlagering 26 bildenden Ringbereich der inneren Materiallage 7 drückt.The bearing ring 26 is expediently in one piece with the inner one Material layer 7 of the base body 5 connected. In this The perforation 9 of the inner material layer 7 has a connection a smaller diameter than the perforation 10 of the outer layer of material 8 so that a radially inward over the edge of the hole 30 of the outer layer of material 8 projecting ring area of the inner layer of material 7 is formed, the in or through the Perforation 10 of the outer material layer projecting bearing ring 26 is formed is. The bearing ring 26 is, so to speak, from the other Level of the inner layer of material 7 slightly or the like. The ring area forming the abutment ring 26 can the inner layer of material 7 at the hole edge 30 of the outer layer of material 8 pressed into the perforation 10 of the outer layer of material 8 his. The manufacturing process can thus be as follows that with an otherwise finished connector, the hole edge 30 of the outer layer of material 8 takes, so to speak, as a shape in which the ring area of the inner material layer forming the abutment ring 26 7 presses.
