Description

Die Erfindung bezieht sich auf eine Einrichtung zur Festlegung eines elektrischen oder elektronischen Bauteiles mit einem Gehäuse, beispielsweise eines Steckerteiles, eines Kupplungsteiles, eines Sensors oder dergleichen in einer Durchgangsöffnung einer Chassiswand oder eines Maschinenelementes.The invention relates to a device for fixing an electrical or electronic component with a housing, for example a plug part, a coupling part, a sensor or the like in a through opening of a chassis wall or a machine element.

Bislang wurden in solchen Fällen am Gehäuse des Bauteiles Laschen vorgesehen mit Aufnahmebohrungen für Befestiger wie Schrauben, Nieten od. dgl. Mit diesen Befestigern wurde das Gehäuse des Bauteiles in der Durchgangsöffnung festgeschraubt oder festgelegt. Der damit verbundene Montageaufwand ist nicht unerheblich. In diesem Zusammenhang ist beispielsweise die DE-PS 11 35 069 zu nennen, die eine solche Konstruktion zeigt oder auch das DE-GM 18 23 748, das die Festlegung eines Kondensators an einem Gehäusedurchgang veranschaulicht, wobei am Rand des Gehäusedurchganges festschraubbare Klemmlaschen einen am Kondensatorgehäuse radial vorspringenden Bund formschlüssig und klemmend fassen.So far, in such cases, tabs have been provided on the housing of the component with mounting holes for fasteners such as screws, rivets or the like. With these fasteners, the housing of the component has been screwed or fixed in the through opening. The associated assembly effort is not insignificant. In this connection, for example, DE-PS 11 35 069 is to be mentioned, which shows such a construction, or also DE-GM 18 23 748, which illustrates the fixing of a capacitor to a housing passage, with clamp tabs which can be screwed onto the edge of the housing passage, one on the capacitor housing grasp the radially projecting collar in a form-fitting and clamping manner.

Auch das DE-GM 94 10 147 ist hier zu erwähnen, das ein elektrisches Anschlußsystem veranschaulicht, insbesondere zum Anschluß eines Verschleißanzeigesensors einer Bremse. Hier ist ein Steckverbinderhalter vorgesehen, der in einer Bohrung eines Gehäuseteiles festlegbar ist, wobei er in dieser Bohrung durch eine stirnseitige Anlageschulter einerseits und durch Rasthaken andererseits gehalten ist. Es sind hier keine Maßnahmen vorgesehen, die den Steckverbinderhalter in seiner Lage sichern. Dieser Steckverbinderhalter bildet im Anschlußsystem eine Schnittstelle und dient zur Aufnahme von Steckkontaktelementen.DE-GM 94 10 147 is also to be mentioned here, which illustrates an electrical connection system, in particular for connecting a wear indicator sensor of a brake. Here, a connector holder is provided, which can be fixed in a bore in a housing part, wherein it is held in this bore by an end-side contact shoulder on the one hand and by locking hooks on the other. No measures are provided here to secure the connector holder in place. This connector holder forms an interface in the connection system and serves to accommodate plug contact elements.

Ausgehend von diesem Stand der Technik zielt die Erfindung darauf ab, eine Einrichtung vorzusehen, die die Montage eines solchen Bauteiles, seine Festlegung in einer Durchgangsöffnung einer Chassiswand oder eines Maschinenelementes erleichtert, und zwar vor allem in der Weise, daß die Montage ohne Zuhilfenahme von Werkzeugen bewerkstelligt werden kann, und die vor allem in ihrer betriebsmäßig vorgesehenen Lage ohne zusätzlichen konstruktiven Aufwand gesichert ist. Zur Lösung dieser Aufgabe schlägt die Erfindung jene Maßnahmen vor, die Inhalt und Gegenstand des kennzeichnenden Teiles des Patentanspruches 1 sind. Zweckmäßige Ausführungsformen der Erfindung sind in den Unteransprüchen festgehalten.Based on this prior art, the invention aims to provide a device that facilitates the assembly of such a component, its fixing in a through opening of a chassis wall or a machine element, especially in such a way that the assembly without the use of tools can be accomplished, and which is secured especially in its operationally intended location without additional design effort.

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 Stirnseite 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 which is made in one piece from a resistant plastic material. This sleeve 1 has a cylindrical jacket 2. From the lower end face 3 of this sleeve 1, pairs of substantially axially parallel incisions 4 are provided at diametrically lying locations, through which 2 tabs 5 are cut free from this jacket, at the ends of which a radially projecting one , in cross section hook-shaped collar 6 is provided. The boundary surface of the collar 6 facing the end face 3 is chamfered like a wedge. It can be seen from FIGS. 1 and 5 that these pairs of tabs 5 extend over a considerable part of the length of the sleeve 1 and that their ends having the collar 6 are set back somewhat from the end face 3 of the sleeve 1. A radially projecting shoulder 7 is integrally formed on this sleeve 1, which merges into the sleeve 1 to form an inner shoulder 8 and an outer shoulder 9. The sleeve 1 has an outer and an inner circular cross section (Fig. 3). The receiving space delimited by the shoulder 7 and the inner shoulder is oval here (FIG. 2, FIG. 4). In the shoulder 7 of the sleeve 1, guide slots 10 are recessed in a position diametrically opposite one another. An imaginary plane containing these guide slots 10 is at right angles to the axis of the sleeve 1. At opposite locations, these guide slots 10 have an interior the sleeve 1 out openings 12. These guide slots 10 are open on opposite sides and radially outwards (Fig. 4), and they serve to receive 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) which protrude through the openings 12 when the wire spring 11 is inserted and protrude into the oval receiving space delimited by the shoulder 7 and the inner shoulder 8. These bends 14 of the legs 13 of the wire spring 11 in the locked position (FIG. 4) are in relation to the direction of displacement (arrow 15) of the wire spring 11 on surfaces 16 and 17 which are inclined to this direction. It can also be seen from FIGS. 2 and 4 that when the wire spring 11 is in the locked position, the web 18 connecting the legs 13 thereof is distanced from the jacket of the sleeve 1 or from the shoulder 7 thereof. A longitudinal groove 19 is also formed on the sleeve 1 and forms a vertically extending positioning slot.

Wenn vorstehend von oben und unten gesprochen wird, so beziehen sich diese Angaben auf die Darstellungen in den Figuren.If the above and below are spoken of, this information relates to 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 FIGS. 6 to 8 in different views. It has a cylindrical housing 21 with a projecting, strip-like, longitudinal cam 22 and with cross-sectional dimensions which correspond in terms of their shape and size to the inner cross-section of the sleeve 1 (FIG. 3). At the top of this housing 21 is a collar 23 of oval shape, which is designed to correspond to the upper receiving space of the sleeve 1, which is delimited by the shoulder 7 and the inner shoulder 8 of this sleeve 1. At opposite points, 23 grooves 24 are formed on this collar. Cables 26 and 27 are introduced through an overhead grommet 25.

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 end face 28. However, this component 20 can also be closed in a pot shape and have components in its interior that can be influenced, for example, capacitively, inductively or magnetically, if this component 20 is designed as a sensor.

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.If this component 20 is now to be fixed in a through opening 29 of a machine element 30 (FIGS. 9 to 11), the prepared through opening is inserted 29 inserted the sleeve 1, with its end face 3 ahead. The sleeve 1 is adapted to the machine element 30 insofar as the distance H of the shoulder 7 from the collar 6 of the tab 5 corresponds to the thickness S of the machine element 30. When inserting the sleeve 1 into the through opening 29, the tabs 5 initially deflect radially inwards until the shoulder 7 abuts the machine element 30 and the collar 6 of the two tabs 5 lies outside the through opening 29, so that the tabs 5 are inherent Resilience resume their original position, the collars 6 of the tabs engage positively behind the edge of the through opening 29 (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 retracted so that the bends 14 withdraw from the openings 12, this retraction of the wire spring 11 being facilitated by the fact that the web 18 is easy to grasp due to its distant position relative to the sleeve and due to the inclined surfaces 17 which when Withdrawing the wire spring 11, spread the legs 13 outwards. The component 20 is then inserted into the sleeve in the correct position, the strip-shaped cam 22 being received by the longitudinal groove 19. As a result, the component 20 is positioned radially. The component 20 is pushed into the sleeve 1 until the collar 23 lies in the receiving space delimited by the shoulder 7 and the inner shoulder 8. Now the grooves 24 are located 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 then pushed into its locking position, the bends 14 engage the grooves 24 in a positive manner. The component 20 is thus fixed in the sleeve 1 in the axial direction. As can be seen from FIG. 11, the housing 21 of the component 20 bears directly on the back of the tabs 5, so that the tabs can no longer deflect radially inwards. In this way, the component 20 is securely fixed in the through opening 29 of the machine element 30 without the aid of a tool.

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 Riegelglieder 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 Stirnseite 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, a plurality of incisions 4 can be provided in the jacket 2 of the sleeve 1, so that the jacket 2 of the sleeve consists of numerous tabs. Instead of a displaceably mounted locking element 11, pivoting locking elements can also be attached to the shoulder 7, or the locking element can be designed as a plug pin which can be inserted into a guide slot or into a guide bore. In the Arrangement of tabs 5 in pairs, as shown in the exemplary embodiment, the housing 21 of the component 20 can be designed with respect to its cross sections such that the housing 21 only rests on the inside of the tabs in order to fix them in their position. The cross-sectional shape of the housing 21 can therefore deviate from the inner cross section of the sleeve 1. The housing 21 of the component 20 can also be longer than the sleeve 1, so that it protrudes from the end face 3 thereof. The length of the sleeve 1 and the length of the component 20 will generally 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.

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. Werden in der Folge die Laschen 5 der Hülse 1 gegeneinander gedrückt, so kann auch die Hülse aus der Durchgangsöffnung 29 herausgezogen werden. Auch für diese Demontageschritte sind keine Werkzeuge notwendig.If the device is to be dismantled, the wire spring 11 is retracted in the exemplary embodiment shown, so that its bends 14 pass out of the grooves 24 of the collar 23. The component 20 can then be pulled out of the sleeve. If the tabs 5 of the sleeve 1 are subsequently pressed against one another, the sleeve can also be pulled out of the through opening 29. No tools are required for these disassembly steps either.
