Die Einrichtung besitzt eine Hülse 1, die aus einem widerstandsfähigen Kunststoffmaterial einstückig gefertigt ist. Diese Hülse 1 besitzt einen zylindrischen Mantel 2. Von der unteren Stirnseite 3 dieser Hülse 1 gehen an diametral liegenden Stellen paarweise vorgesehene, im wesentlichen achsparallele Einschnitte 4 aus, durch welche aus diesem Mantel 2 Laschen 5 freigeschnitten sind, an deren Enden je ein radial auskragender, im Querschnitt hakenförmiger Bund 6 vorgesehen ist. Die der Stimseite 3 zugewandte Begrenzungsfläche des Bundes 6 ist keilartig abgeschrägt. Aus den Figuren 1 und 5 ist ersichtlich, daß sich diese paarweise vorgesehenen Laschen 5 über einen erheblichen Teil der Länge der Hülse 1 erstrecken und daß ihre den Bund 6 aufweisenden Enden gegenüber der Stirnseite 3 der Hülse 1 etwas zurückversetzt sind. Oben ist an dieser Hülse 1 eine radial auskragende Schulter 7 angeformt, welche unter Bildung eines inneren Absatzes 8 und eines äußeren Absatzes 9 in die Hülse 1 übergeht. Die Hülse 1 besitzt einen äußeren und einen inneren kreisförmigen Querschnitt (Fig. 3). Der durch die Schulter 7 und den inneren Absatz begrenzte Aufnahmeraum ist hier oval ausgestaltet (Fig. 2, Fig. 4). In der Schulter 7 der Hülse 1 sind in zueinander diametraler Lage Führungsschlitze 10 ausgespart. Eine gedachte, diese Führungsschlitze 10 beinhaltende Ebene steht dabei rechtwinkelig zur Achse der Hülse 1. An einander gegenüberliegenden Stellen besitzen diese Führungsschlitze 10 gegen das Innere der Hülse 1 hin Öffnungen 12. Diese Führungsschlitze 10 sind nach entgegengesetzten Seiten und radial nach außen hin offen (Fig. 4), und sie dienen zur Aufnahme eines Riegelgliedes, das hier als U-förmige Drahtfeder 11 ausgebildet ist.The device has a sleeve 1 made of a resistant plastic material is made in one piece. This sleeve 1 has a cylindrical Jacket 2. From the lower end face 3 of this sleeve 1 go to diametrically lying Incisions 4, which are provided in pairs and are essentially axially parallel from, through which 2 tabs 5 are cut out of this jacket, at their A radially projecting collar 6 with a hook-shaped cross section is provided at each end is. The boundary surface of the collar 6 facing the front side 3 is wedge-like beveled. From Figures 1 and 5 it can be seen that these are in pairs provided tabs 5 over a significant part of the length of the sleeve 1st extend and that their collar 6 ends opposite the end face 3 of the sleeve 1 are set back somewhat. At the top of this sleeve 1 is a radial cantilevered shoulder 7 which is formed to form an inner shoulder 8 and an outer shoulder 9 merges into the sleeve 1. The sleeve 1 has one outer and an inner circular cross section (Fig. 3). The one through the Shoulder 7 and the inner paragraph limited receiving space is oval here (Fig. 2, Fig. 4). In the shoulder 7 of the sleeve 1 are diametrically opposed to each other Position of guide slots 10 recessed. An imaginary, these guide slots 10 containing plane is perpendicular to the axis of the sleeve 1. At each other opposite points have these guide slots 10 against the inside the sleeve 1 out openings 12. These guide slots 10 are opposite Open sides and radially outward (Fig. 4), and they are used for receiving a locking member, which is designed here as a U-shaped wire spring 11.

Die Schenkel 13 dieser U-förmigen Drahtfeder 11 besitzen gegeneinander gerichtete Ausbiegungen 14 (Fig. 4), die bei eingesetzter Drahtfeder 11 durch die Öffnungen 12 ragen und in den ovalen, von der Schulter 7 und vom inneren Absatz 8 begrenzten Aufnahmeraum vorstehen. Diese Ausbiegungen 14 der Schenkel 13 der in Verriegelungsstellung befindlichen Drahtfeder 11 (Fig. 4) liegen, bezogen auf die Verschieberichtung (Pfeil 15) der Drahtfeder 11, an zu dieser Richtung schräg liegenden Flächen 16 und 17 an. Aus den Figuren 2 und 4 ist auch ersichtlich, daß bei in Verriegelungsstellung befindlicher Drahtfeder 11 der die Schenkel 13 derselben verbindende Steg 18 vom Mantel der Hülse 1 bzw. von deren Schulter 7 distanziert liegt. An der Hülse 1 ist noch eine Längsnut 19 ausgeformt, die einen vertikal verlaufenden Positionierschlitz bildet.The legs 13 of this U-shaped wire spring 11 have mutually directed Bends 14 (Fig. 4), when the wire spring 11 is inserted through the openings 12 protrude and in the oval, from the shoulder 7 and from the inner paragraph 8 project limited space. These bends 14 of the legs 13 the wire spring 11 located in the locking position (FIG. 4) are related on the direction of displacement (arrow 15) of the wire spring 11, to this direction sloping surfaces 16 and 17. FIGS. 2 and 4 also show that when the wire spring 11 is in the locked position, the legs 13 same connecting web 18 from the jacket of the sleeve 1 or from the shoulder 7 is distant. On the sleeve 1, a longitudinal groove 19 is formed, the forms a vertical positioning slot.

Wenn vorstehend von oben und unten gesprochen wird, so beziehen sich diese Angaben auf die Darstellungen in den Figuren.When the above and below are spoken of, they relate Information on the representations in the figures.

Der von dieser Hülse 1 aufzunehmende elektrische oder elektronische Bauteil 20 ist in den Figuren 6 bis 8 in verschiedenen Ansichten gezeigt. Er besitzt hier ein zylindrisches Gehäuse 21 mit einem vorspringenden, leistenartigen, längsverlaufenden Nocken 22 und mit Querschnittsabmessungen, die hinsichtlich ihrer Form und ihrer Größe dem inneren Querschnitt der Hülse 1 (Fig. 3) entsprechen. Nach oben hin schließt an dieses Gehäuse 21 ein Kragen 23 von ovaler Form an, der korrespondierend ausgebildet ist zum oberen Aufnahmeraum der Hülse 1, der von der Schulter 7 und dem inneren Absatz 8 dieser Hülse 1 begrenzt ist. An einander gegenüberliegenden Stellen sind an diesem Kragen 23 Nuten 24 ausgeformt. Über eine oben liegende Tülle 25 sind Kabel 26 und 27 eingeleitet.The electrical or electronic component 20 to be received by this sleeve 1 is shown in Figures 6 to 8 in different views. He owns one here cylindrical housing 21 with a projecting, strip-like, longitudinal Cam 22 and with cross-sectional dimensions in terms of their shape and their size correspond to the inner cross section of the sleeve 1 (Fig. 3). After A collar 23 of oval shape adjoins this housing 21 at the top is designed to correspond to the upper receiving space of the sleeve 1, the the shoulder 7 and the inner shoulder 8 of this sleeve 1 is limited. To each other Opposite points are 23 grooves 24 formed on this collar. over an overhead grommet 25, cables 26 and 27 are introduced.

Dieser Bauteil 20 kann beispielsweise als Stecker ausgebildet sein mit einer offenen Stirnseite 28. Dieser Bauteil 20 kann aber auch topfförmig geschlossen sein und in seinem Inneren Bauelemente aufweisen, die beispielsweise kapazitiv, induktiv oder magnetisch beeinflußbar sind, wenn dieser Bauteil 20 als Sensor ausgebildet ist.This component 20 can be designed, for example, as a plug with an open one Face 28. This component 20 can also be closed in a pot shape and have components inside, for example capacitive, inductive or can be influenced magnetically if this component 20 is designed as a sensor is.

Soll dieser Bauteil 20 nun in einer Durchgangsöffnung 29 eines Maschinenelementes 30 festzulegen sein (Fig. 9 bis 11), so wird in die vorbereitete Durchgangsöffnung 29 die Hülse 1 eingeschoben, und zwar mit ihrer Stirnseite 3 voraus. Die Hülse 1 ist dem Maschinenelement 30 insofern angepaßt, als der Abstand H der Schulter 7 vom Bund 6 der Lasche 5 der Stärke S des Maschinenelementes 30 entspricht. Beim Einschieben der Hülse 1 in die Durchgangsöffnung 29 weichen vorerst die Laschen 5 radial nach innen aus, bis die Schulter 7 am Maschinenelement 30 anliegt und der Bund 6 der beiden Laschen 5 außerhalb der Durchgangsöffnung 29 liegt, so daß die Laschen 5 aufgrund der ihnen innewohnenden Elastizität ihre ursprüngliche Lage wieder einnehmen, wobei die Bünde 6 der Laschen den Rand der Durchgangsöffnung 29 formschlüssig hintergreifen (Fig. 11). Damit ist vorerst die Hülse 1 in der Durchgangsöffnung 29 fixiert.Should this component 20 now be in a through opening 29 of a machine element 30 to be determined (Fig. 9 to 11), it is in the prepared through opening 29 inserted the sleeve 1, with its end face 3 ahead. The sleeve 1 is adapted to the machine element 30 in that the distance H the shoulder 7 from the collar 6 of the tab 5 of the thickness S of the machine element 30 corresponds. When inserting the sleeve 1 into the through opening 29 initially the tabs 5 radially inwards until the shoulder 7 on the machine element 30 abuts and the collar 6 of the two tabs 5 outside the through opening 29 lies, so that the tabs 5 due to their inherent elasticity return to their original position, the frets 6 of the tabs reach behind the edge of the through opening 29 in a form-fitting manner (FIG. 11). For the time being, the sleeve 1 is fixed in the through opening 29.

Nun wird die Drahtfeder 11 zurückgezogen, so daß die Ausbiegungen 14 aus den Öffnungen 12 zurückweichen, wobei dieses Zurückziehen der Drahtfeder 11 dadurch erleichtert wird, daß der Steg 18 leicht faßbar ist aufgrund seiner distanzierten Lage gegenüber der Hülse und aufgrund der Schrägflächen 17, die beim Zurückziehen der Drahtfeder 11 die Schenkel 13 nach außen spreizen. Anschließend wird der Bauteil 20 positionsgerecht in die Hülse eingeführt, wobei der leistenförmige Nocken 22 von der Längsnut 19 aufgenommen wird. Dadurch ist der Bauteil 20 radial positioniert. Der Bauteil 20 wird soweit in die Hülse 1 eingeschoben, bis der Kragen 23 in dem von der Schulter 7 und dem inneren Absatz 8 begrenzten Aufnahmeraum liegt. Nun befinden sich die Nuten 24 am Kragen 23 des Bauteiles 20 in deckungsgleicher Lage mit den Öffnungen 12 in den Führungsschlitzen 10, so daß, wenn nun nachfolgend die Drahtfeder 11 in ihre Verriegelungsstellung geschoben wird, deren Ausbiegungen 14 in die Nuten 24 formschlüssig eingreifen. Damit ist der Bauteil 20 in axialer Richtung in der Hülse 1 festgelegt. Wie aus Fig. 11 ersichtlich, liegt das Gehäuse 21 des Bauteiles 20 direkt an den Laschen 5 rückseitig an, so daß die Laschen nicht mehr radial nach innen ausweichen können. Auf diese Weise ist der Bauteil 20 in der Durchgangsöffnung 29 des Maschinenelementes 30 ohne Zuhilfenahme eines Werkzeuges sicher festgelegt.Now the wire spring 11 is withdrawn so that the bends 14 from the Retreat openings 12, this retraction of the wire spring 11 thereby is facilitated that the web 18 is easy to grasp due to its distance Position opposite the sleeve and due to the inclined surfaces 17, which when retracting the wire spring 11 spread the legs 13 outwards. Subsequently the component 20 is inserted in the correct position in the sleeve, the strip-shaped Cam 22 is received by the longitudinal groove 19. This is the Component 20 positioned radially. The component 20 is inserted into the sleeve 1 until until the collar 23 in the shoulder 7 and the inner paragraph 8 limited recording space. The grooves 24 are now on the collar 23 of the component 20 in a congruent position with the openings 12 in the guide slots 10, so that when the wire spring 11 is now in its locked position is pushed, the bends 14 in the grooves 24 positively intervention. The component 20 is thus in the sleeve 1 in the axial direction fixed. As can be seen from FIG. 11, the housing 21 of the component 20 lies directly on the tabs 5 on the back, so that the tabs no longer radially inwards can dodge. In this way, the component 20 is in the through opening 29 of the machine element 30 safely without the aid of a tool fixed.

Es liegt im Rahmen der Erfindung, die Hülse 1 beispielsweise eckig auszubilden. Anstelle von zwei diametral liegenden Laschen 5 können im Mantel 2 der Hülse 1 eine Vielzahl von Einschnitten 4 vorgesehen werden, so daß der Mantel 2 der Hülse aus zahlreichen Laschen besteht. Anstelle eines verschiebbar gelagerten Riegelgliedes 11 können auch schwenkbare Riegel glieder an der Schulter 7 angelängt sein, oder das Riegelglied kann als Steckbolzen ausgebildet werden, der in einen Führungsschlitz oder in eine Führungsbohrung einschiebbar ist. Bei der paarweisen Anordnung von Laschen 5, wie im Ausführungsbeispiel gezeigt, kann das Gehäuse 21 des Bauteiles 20 bezüglich seines Querschnitte so ausgebildet sein, daß das Gehäuse 21 nur inseitig an den Laschen anliegt, um diese in ihrer Lage zu fixieren. Die Querschnittsform des Gehäuses 21 kann also vom Innenquerschnitt der Hülse 1 abweichen. Das Gehäuse 21 des Bauteiles 20 kann auch länger sein als die Hülse 1, so daß es gegenüber deren Stimseite 3 vorsteht. Die Länge der Hülse 1 und die Länge des Bauteiles 20 werden im allgemeinen aufeinander abgestimmt sein. Die Länge der Laschen 5 hingegen ergibt sich aus der Wandstärke des Chassis oder des Maschinenelementes, an dem der Bauteil festzulegen ist.It is within the scope of the invention to design the sleeve 1, for example, as angular. Instead of two diametrically lying tabs 5, the sleeve 1 can be in the jacket 2 a plurality of incisions 4 are provided so that the jacket 2 of the Sleeve consists of numerous tabs. Instead of a slidably mounted Bolt member 11 can also be pivoted bolt members attached to the shoulder 7 be, or the locking member can be designed as a plug pin, which in a guide slot or can be inserted into a guide bore. In the paired arrangement of tabs 5, as shown in the embodiment can the housing 21 of the component 20 is designed with respect to its cross sections be that the housing 21 rests only on the inside of the tabs to this in their Fix location. The cross-sectional shape of the housing 21 can thus be from the inner cross section the sleeve 1 deviate. The housing 21 of the component 20 can also be longer than the sleeve 1, so that it protrudes from the front side 3. The The length of the sleeve 1 and the length of the component 20 are generally one on the other be coordinated. The length of the tabs 5, however, results from the Wall thickness of the chassis or the machine element on which the component is to be fixed is.

Soll die Einrichtung demontiert werden, so wird im gezeigten Ausführungsbeispiel die Drahtfeder 11 zurückgezogen, so daß deren Ausbiegungen 14 aus den Nuten 24 des Kragens 23 gelangen. Dann kann der Bauteil 20 aus der Hülse herausgezogen werden.
