Description

Die vorliegende Erfindung betrifft eine Leuchte mit einem Leuchtengehäuse mit einem Loch und einem Federelement zur Herstellung eines Erdungsanschlusses sowie gegebenenfalls weiteren Teilen der Leuchte, wie zum Beispiel einem Leuchtmittel, einem Treiber, einem EVG (elektronisches Vorschaltgerät), einer Abdeckung, einem Montageelement und/oder einem Geräteträger.The present invention relates to a luminaire with a luminaire housing with a hole and a spring element for producing a grounding connection and possibly other parts of the luminaire, such as a light source, a driver, an EVG (electronic ballast), a cover, an assembly element and / or an equipment carrier.

Leuchten und viele weitere elektrische Betriebsgeräte werden gemäß DIN EN 61140 (VDE 0140-1) in Schutzklassen eingeteilt und müssen Sicherheitsmaßnahmen zum Schutz gegen elektrische Schläge beim Berühren der unter Spannung stehenden Teile im Betriebsfehlerfall aufweisen. Dies ist vor allem bei Leuchtengehäusen aus leitenden Materialien relevant. Um das elektrisch leitfähige Gehäuse mit dem Schutzleitersystem der Leuchte zu verbinden, wird die Verbindung zu dem Leuchtengehäuse durch eine Schraube im Leuchtengehäuse hergestellt. An dieser Schraube wird ein Erdungskabel angeschlossen.Luminaires and many other electrical operating devices are divided into protection classes in accordance with DIN EN 61140 (VDE 0140-1) and must have safety measures to protect against electric shocks when touching live parts in the event of an operating fault. This is particularly relevant for luminaire housings made of conductive materials. In order to connect the electrically conductive housing with the protective conductor system of the light, the connection to the light housing is made by a screw in the light housing. A grounding cable is connected to this screw.

Ein Nachteil dieser Befestigungsart besteht jedoch darin, dass für das zusätzliche Setzen dieser Schraube zur Verbindung mit dem Leuchtengehäuse in der Produktion ein weiterer Arbeitsschritt benötigt wird.A disadvantage of this type of fastening, however, is that a further work step is required for the additional setting of this screw for connection to the lamp housing in production.

Aufgabe der vorliegenden Erfindung ist es, eine Leuchte mit einem Erdungsanschluss bereitzustellen, welche einfach und kostengünstig herstellbar ist.The object of the present invention is to provide a lamp with an earth connection which can be produced simply and inexpensively.

Gelöst wird die Aufgabe durch eine Leuchte nach Anspruch 1.The object is achieved by a lamp according to claim 1.

Eine Besonderheit der erfindungsgemäßen Leuchte besteht in der Art, wie der Erdungsanschluss hergestellt wird. Anstatt eine Schraube einzudrehen, wird einfach ein Federelement in ein Loch eingesteckt, welches sich selbständig darin verspreizt. Durch die Verspreizung der Schenkel des Federelements wird gleichzeitig der mechanische Halt und ein ausreichender elektrischer Kontakt zu dem Material des Leuchtengehäuses hergestellt. Dieser Kontakt genügt, um eine ausreichend niederohmige Verbindung zwischen dem Kontaktelement an dem Federelement und dem Leuchtengehäuse herzustellen. Das Federelement weist den Vorteil auf, dass es durch eine einfache Steckbewegung in das Loch des Gehäuses eingeschoben werden kann. Eine Drehung, wie bei einer Schraube, ist nicht erforderlich. Daher ist der entsprechende Produktionsschritt vereinfacht. Ferner ist das Federelement auch kostengünstiger als eine Schraube herzustellen.A special feature of the lamp according to the invention is the way in which the ground connection is established. Instead of screwing in a screw, a spring element is simply inserted into a hole, which expands by itself. By spreading the legs of the spring element, the mechanical hold and sufficient electrical contact to the material of the lamp housing is produced at the same time. This contact is sufficient to produce a sufficiently low-resistance connection between the contact element on the spring element and the lamp housing. The spring element has the advantage that it can be pushed into the hole in the housing with a simple plug-in movement. Rotation, as with a screw, is not required. The corresponding production step is therefore simplified. Furthermore, the spring element is also cheaper to manufacture than a screw.

Gemäß einer bevorzugten Ausführungsform stehen die Schenkel des Federelements V-förmig oder L-förmig zueinander. Die V- oder L-Form hat den Vorteil, dass die zwei Schenkel bereits eine Spitze definieren, die es erlaubt, das Federelement in das Loch einzustecken, so dass die Schenkel zusammengedrückt werden, um sich in dem Loch zu verspreizen. Dabei ist zu verstehen, dass das offene Ende der V-Form bzw. der L-Form in dem Zustand, welchen die Feder außerhalb des Lochs annimmt, größer als ein Lochdurchmesser ist, in dem das Federelement eingesteckt wird.According to a preferred embodiment, the legs of the spring element are V-shaped or L-shaped to one another. The V- or L-shape has the advantage that the two legs already define a point which allows the spring element to be inserted into the hole so that the legs are pressed together in order to spread apart in the hole. It is to be understood that the open end of the V-shape or the L-shape in the state assumed by the spring outside the hole is larger than a hole diameter into which the spring element is inserted.

Gemäß einer bevorzugten Ausführungsform weisen die wenigstens zwei Schenkel zwei unterschiedliche Längen auf, wobei der längere Schenkel in dem Loch liegt und mindestens bis zu der Kante oberhalb des Lochs reicht und die kürzeren Schenkel im Loch unterhalb der Oberkante des Lochs angeordnet sind. Der kürzere Schenkel ist mit einem Ende mit dem längeren Schenkel verbunden, liegt mit dem entgegengesetzten Ende an der Innenwand des Lochs an und verspreizt sich gegen den langen Schenkel. Die Konstruktion mit einem kürzerem und einem längeren Schenkel hat den Vorteil, dass der kürzere Schenkel mit einer Schneidkante an der Innenwand des Lochs anliegt, um die Halterung des Federelements in dem Loch zu gewährleisten, während der längere Schenkel aus dem Loch herausragt, um an diesem Bereich die Kontaktfläche für den Erdungsanschluss vorzusehen. Außer den beiden Schenkeln mit der Kontaktfläche werden tatsächlich keine weiteren Elemente für das Federelement benötigt. Es ist dadurch besonders einfach herzustellen.According to a preferred embodiment, the at least two legs have two different lengths, the longer leg lying in the hole and at least as far as the edge above the hole and the shorter legs being arranged in the hole below the upper edge of the hole. The shorter leg is one end with the longer leg connected, rests with the opposite end on the inner wall of the hole and expands against the long leg. The construction with a shorter and a longer leg has the advantage that the shorter leg rests with a cutting edge on the inner wall of the hole in order to ensure that the spring element is held in the hole, while the longer leg protrudes from the hole in order to use it Area to provide the contact surface for the earth connection. Apart from the two legs with the contact surface, no further elements are actually required for the spring element. This makes it particularly easy to manufacture.

Gemäß einer bevorzugten Ausführungsform ist an dem Federelement ein Abschnitt mit einer Anschlagskante ausgeprägt, wobei die Anschlagskante an mindestens einem Bereich, vorzugsweise an zwei Bereichen, auf der Oberkante des Lochs aufliegt, wodurch die Anschlagskante einen Tiefenanschlag für das Federelement in dem Loch bildet. Der Tiefenanschlag der Anschlagskante hat den Vorteil, dass die Einstecktiefe des Federelements festgelegt ist. Dies ist vorteilhaft, weil die sich verspreizenden Schenkel in dem Loch eine Bewegung der Feder nur entgegen der Einschubrichtung sichern. Durch den Tiefenanschlag in Kombination mit der Verspreizung der Federschenkel ist daher das Federelement in dem Loch in der Einschubrichtung und entgegengesetzt der Einschubrichtung festgelegt.According to a preferred embodiment, a section with a stop edge is formed on the spring element, the stop edge resting on the upper edge of the hole in at least one area, preferably in two areas, whereby the stop edge forms a depth stop for the spring element in the hole. The depth stop of the stop edge has the advantage that the insertion depth of the spring element is fixed. This is advantageous because the spreading legs in the hole only ensure movement of the spring against the direction of insertion. Due to the depth stop in combination with the expansion of the spring legs, the spring element is therefore fixed in the hole in the direction of insertion and opposite to the direction of insertion.

Gemäß einer bevorzugten Ausführungsform ist der Abschnitt mit der Anschlagskante zwischen dem Ende des längeren Schenkels und der Kontaktfläche ausgeprägt. Bei der Ausführungsform mit zwei unterschiedlich langen Schenkeln ragt der längere Schenkel ohnehin wenigstens bis zur Oberkante des Lochs im Gehäuse. Daher kann dieser Schenkel auch gleich dazu dienen, um die Anschlagkante des Federelements in einer Ausführungsform aufzunehmen.According to a preferred embodiment, the section with the stop edge is formed between the end of the longer leg and the contact surface. In the embodiment with two legs of different lengths, the longer leg protrudes anyway at least to the upper edge of the hole in the housing. Therefore, this leg can also be used to to accommodate the stop edge of the spring element in one embodiment.

Gemäß einer bevorzugten Ausführungsform weisen die zwei Schenkel des Federelements vor dem Einschieben in das Loch ein Winkel von mindestens fünf und höchstens 120° zueinander auf und werden beim Einschieben in das Loch elastisch zusammengedrückt. Die Winkel können abhängig von der Elastizität der Schenkel der Feder variieren. Ein verhältnismäßig spitzer Winkel, z.B. zwischen 5° und 30°, hat den Vorteil, dass die Federkraft auf die Innenwände des Lochs zum Verspreizen der Federn vergleichsweise groß ausgeführt werden kann, da die Schenkel wenig ausgelenkt werden müssen. Ein größerer Winkel, z.B. von 60° bis 120°, hat den Vorteil, dass sich das gleiche Federelement auch für sehr unterschiedliche Lochdurchmesser eignet.According to a preferred embodiment, the two legs of the spring element have an angle of at least five and at most 120 ° to one another before they are inserted into the hole and are elastically compressed when they are inserted into the hole. The angles can vary depending on the elasticity of the legs of the spring. A relatively acute angle, e.g. between 5 ° and 30 °, has the advantage that the spring force on the inner walls of the hole for spreading the springs can be made comparatively large, since the legs have to be deflected little. A larger angle, e.g. from 60 ° to 120 °, has the advantage that the same spring element is also suitable for very different hole diameters.

Gemäß einer bevorzugten Ausführungsform ist das Federelement einstückig in einem Stanzbiegeprozess aus einem Flachmaterial, insbesondere aus einem Federstahl, gebildet. Dies vereinfacht die Herstellung des Federelements. Die Kosten für ein solches Federelement liegen sogar noch unterhalb der Kosten für eine Schraube.According to a preferred embodiment, the spring element is formed in one piece in a stamping and bending process from a flat material, in particular from a spring steel. This simplifies the manufacture of the spring element. The cost of such a spring element is even below the cost of a screw.

Gemäß einer bevorzugten Ausführungsform weist wenigstens einer der Schenkel des Federelements eine Zunge auf, die mit einer zur Kontaktfläche zeigenden Kante oder Spitze an einem Innenwandabschnitt des Lochs anliegt, um das Federelement zusätzlich zu verkrallen. Bei dieser Ausführungsform ist an einem der Schenkel des Federelements oder an beiden Schenkeln je ein zusätzlicher Widerhaken in Form der Zunge gebildet. Diese Zunge kann ggf. in Kombination mit weiteren Kanten des Schenkels ein Zurückschieben des Federelements aus dem Loch verhindern. Beispielsweise kann in der Ausführungsform mit einem längeren und einem kürzeren Schenkel an dem längeren Schenkel eine entsprechende Zunge als Widerhaken vorgesehen sein. Der längere Schenkel liegt an der Innenwand des Lochs nur an, weil sich der längere Schenkel über die Oberkante des Lochs erstreckt. Die zusätzliche Zunge kann hier als Widerhaken wirken, so dass sich auch der längere Schenkel in der Innenwand des Lochs fest verkrallt. Der kürzere Schenkel benötigt nicht unbedingt einen zusätzlichen Widerhaken, weil die Oberkante des kürzeren Schenkels bereits in die Innenwand des Lochs einschneidet, um den Schenkel in dem Loch festzukrallen.According to a preferred embodiment, at least one of the legs of the spring element has a tongue which rests with an edge or point facing the contact surface on an inner wall section of the hole in order to additionally claw the spring element. In this embodiment, an additional barb in the form of the tongue is formed on one of the legs of the spring element or on both legs. This tongue can, if necessary in combination with further edges of the leg, prevent the spring element from being pushed back out of the hole. For example, in the embodiment with a longer leg and a shorter leg a corresponding tongue can be provided as a barb. The longer leg rests against the inner wall of the hole only because the longer leg extends over the top of the hole. The additional tongue can act as a barb, so that the longer leg also clings firmly to the inner wall of the hole. The shorter leg does not necessarily need an additional barb because the upper edge of the shorter leg already cuts into the inner wall of the hole in order to claw the leg in the hole.

Gemäß einer bevorzugten Ausführungsform ist die Kontaktfläche als Flachsteckhülse ausgebildet. Alternativ ist die Kontaktfläche als Flachstecker ausgebildet, auf den gemäß einer anderen bevorzugten Ausführungsform eine Flachsteckhülse aufsteckbar ist, an die eine Erdungsleitung anschließbar ist. Die Verbindung des Federelements mit der Erdungsleitung mittels einer Flachsteckhülse ist einfach und kostengünstig herstellbar. Insbesondere muss die Flachsteckhülse bzw. das Gegenstück der Flachsteckhülse nur auf das Federelement aufgesteckt werden. Gemäß einer Ausführungsform sind keinerlei Schraubverbindungen notwendig, um das Leuchtengehäuse mit der Erdungsleitung zu verbinden. Gemäß einer Weiterbildung dieser Ausführungsformen kann die Kontaktfläche mit einer Vertiefung oder einer Nase ausgeformt sein, um eine Steckverbindung der Flachsteckhülse formschlüssig zu sichern.According to a preferred embodiment, the contact surface is designed as a flat plug-in sleeve. Alternatively, the contact surface is designed as a flat plug, onto which, according to another preferred embodiment, a flat plug-in sleeve can be attached, to which a grounding line can be connected. The connection of the spring element to the grounding line by means of a flat plug-in sleeve can be produced simply and inexpensively. In particular, the flat plug-in sleeve or the counterpart of the flat plug-in sleeve only needs to be plugged onto the spring element. According to one embodiment, no screw connections are necessary in order to connect the lamp housing to the grounding line. According to a further development of these embodiments, the contact surface can be shaped with a recess or a nose in order to secure a plug connection of the flat receptacle in a form-fitting manner.

Gemäß einer bevorzugten Ausführungsform ist das Leuchtengehäuse wenigstens im Bereich des Lochs aus einem metallischen Material ausgebildet, insbesondere aus Aluminium, beispielsweise aus einem Aluminium-Druckguss. Aluminium hat den besonderen Vorteil, dass es einerseits eine sehr gute elektrische Leitfähigkeit bereitstellt und andererseits weich genug ist, so dass eine oder mehrere Kanten der Schenkel des Federelements in das Aluminiummaterial einschneiden, um das Federelement in dem Loch zu halten und einen niederohmigen Kontakt zum Leuchtengehäuse zu bilden.According to a preferred embodiment, the luminaire housing is formed from a metallic material, in particular from aluminum, for example from a die-cast aluminum, at least in the region of the hole. Aluminum has the particular advantage that on the one hand it provides very good electrical conductivity and on the other hand it is soft is enough so that one or more edges of the legs of the spring element cut into the aluminum material in order to hold the spring element in the hole and to form a low-resistance contact with the lamp housing.

Gemäß einer bevorzugten Ausführungsform weist die Mantelfläche des Lochs eine Oberflächentexturierung auf. Die Oberflächentexturierung kann einen verbesserten Halt des Federelements in dem Loch ermöglichen. Beispielsweise können Riffelungen quer zur Längsachse des Loches vorgesehen sein, so dass eine oder mehrere Kanten der Schenkel des Federelements an der Riffelung entgegen der Einsteckrichtung gehalten werden.According to a preferred embodiment, the outer surface of the hole has a surface texturing. The surface texturing can enable an improved hold of the spring element in the hole. For example, corrugations can be provided transversely to the longitudinal axis of the hole, so that one or more edges of the legs of the spring element are held on the corrugation against the direction of insertion.

Gemäß einer bevorzugten Ausführungsform weist das Loch einen runden Querschnitt auf. Der runde Querschnitt lässt sich nicht nur einfach herstellen sondern hat außerdem den Vorteil, dass das gleiche Loch in einer alternativen Anwendung auch als Schraubloch dienen kann. Insbesondere kann vorgesehen sein, dass das Leuchtengehäuse noch weitere, zu dem ersten Loch formgleiche Löcher aufweist. In diese Ausführungsform können variabel Leuchtenbauteile, wie z.B. Vorschaltgeräte, Fassungen oder andere Anbauteile der Leuchte angebracht werden, und in eines der übrigen Löcher noch das erfindungsgemäße Federelement zur Herstellung des Erdungskontakts eingeschoben werden. Das eine oder die mehreren Löcher in dem Leuchtengehäuse können gemäß einer bevorzugten Ausführungsform als Sackloch ausgebildet sein, insbesondere als konisches Sackloch, wobei eine gewindefurchende Schraube in das Sackloch eindringbar ist. Die gewindefurchenden Schrauben sind jedoch für die Herstellung des Erdungsanschlusses nicht erforderlich. Die gewindefurchenden Schrauben sind nur dafür vorgesehen, um ggf. andere elektrische Bauteile, wie z.B. das Vorschaltgerät, an dem Gehäuse zu befestigen.According to a preferred embodiment, the hole has a round cross section. The round cross-section is not only easy to produce but also has the advantage that the same hole can also be used as a screw hole in an alternative application. In particular, it can be provided that the luminaire housing has further holes of the same shape as the first hole. In this embodiment, variable lighting components such as ballasts, sockets or other add-on parts of the lighting fixture can be attached, and the spring element according to the invention for making the grounding contact can be inserted into one of the remaining holes. According to a preferred embodiment, the one or more holes in the lamp housing can be designed as a blind hole, in particular as a conical blind hole, with a thread-forming screw being able to penetrate into the blind hole. However, the self-tapping screws are not required to establish the ground connection. The thread-forming screws are only intended to be used to fasten other electrical components, such as the ballast, to the housing.

In den Figuren 1 bis 3 ist ein Federelement für die Herstellung eines Erdungsanschlusses eines Leuchtengehäuses dargestellt. Das Federelement weist zwei Schenkel 10 und 20 auf, die eine V-Form einnehmen. Die Spitze α der V-Form ist in der dargestellten Ausführungsform etwa 8° (siehe Figur 3). Sie kann in unterschiedlichen Ausführungsformen jedoch bis zu 120° betragen. Die beiden Schenkel sind in einem Stück aus einem flachen Federstahl durch einen Biegestanzprozess hergestellt.In the Figures 1 to 3 shows a spring element for the production of a ground connection of a lamp housing. The spring element has two legs 10 and 20 which assume a V shape. The tip α of the V-shape is about 8 ° in the illustrated embodiment (see Figure 3 ). In different embodiments, however, it can be up to 120 °. The two legs are made in one piece from flat spring steel by means of a bending stamping process.

An dem längeren Schenkel 10 setzt sich ferner ein Abschnitt 30 fort, der eine größere Breite als der Schenkel 10 aufweist. Der Abschnitt 30 bildet einen Anschlag für das Federelement in dem Loch. Die Unterkante des Abschnitts 30 liegt auf einer Oberkante des Lochs im montierten Zustand der Feder auf.A section 30, which has a greater width than the leg 10, also continues on the longer leg 10. The section 30 forms a stop for the spring element in FIG the hole. The lower edge of the section 30 rests on an upper edge of the hole in the assembled state of the spring.

Über dem Abschnitt 30 erstreckt sich ein Kontaktbereich 40. Dieser ist dafür eingerichtet, um ein Erdungskabel (in den Figuren nicht dargestellt) daran anzuschließen. Das Erdungskabel kann beispielsweise mit einem Flachstecker auf dem Kontaktbereich 40 aufgesteckt werden. Alternativ kann das Erdungskabel auch direkt an der Kontaktfläche z.B. durch Punktschweißen oder durch Anlöten angebracht werden. Vorzugsweise ist, wie in den Figuren 1 und 2 dargestellt, in der Kontaktfläche 40 eine Vertiefung, in der dargestellten Ausführungsform ein Loch, vorgesehen. Diese Vertiefung kann mit einer Federnase einer Flachsteckerhülse zusammenwirken, um den Flachsteckerhülse auf der Kontaktfläche 40 zu halten. Alternativ kann das Loch auch dazu verwendet werden, um ein Erdungskabel direkt an der Kontaktfläche anzulöten oder anzuschweißen. Gemäß einer weiteren Alternative kann die Kontaktfläche 40 selbst auch als Flachsteckerhülse ausgebildet sein, in welche ein Flachstecker des Erdungskabels eingeschoben wird.A contact area 40 extends over section 30. This is designed to connect a grounding cable (not shown in the figures) to it. The grounding cable can be plugged onto the contact area 40 with a flat plug, for example. Alternatively, the grounding cable can also be attached directly to the contact surface, for example by spot welding or soldering. Preferably, as in the Figures 1 and 2 shown, in the contact surface 40 a recess, in the embodiment shown, a hole is provided. This recess can cooperate with a spring nose of a flat connector sleeve in order to hold the flat connector sleeve on the contact surface 40. Alternatively, the hole can also be used to solder or weld a grounding cable directly to the contact surface. According to a further alternative, the contact surface 40 itself can also be designed as a flat connector sleeve into which a flat connector of the grounding cable is inserted.

Die Figur 4 stellt im Querschnitt einen Abschnitt des Leuchtengehäuses 110 dar. Das Leuchtengehäuse 110 weist ein Sackloch 100 auf, welches beispielsweise einen Durchmesser aufweist, der für eine DIN-normgemäße Schraube (M3 bis M8) vorgesehen ist. In der vorliegenden Erfindung wird an diesem Loch das Federelement jedoch ohne jegliche Verschraubung nur durch Einstecken und Verspreizen des Federelements gehalten. Wie in der Figur 5 dargestellt, verspreizt sich der kürzere Schenkel 20 gegenüber dem längeren Schenkel 10, wobei eine Oberkante des kürzeren Schenkels 20 in das Material der Innenwand des Lochs einschneidet. Alleine durch dieses Einschneiden ist es gewährleistet, dass das Federelement nicht entgegen der Einschubrichtung aus dem Loch herausgezogen werden kann.The Figure 4 shows a section of the lamp housing 110 in cross section. The lamp housing 110 has a blind hole 100 which, for example, has a diameter that is provided for a DIN-standard screw (M3 to M8). In the present invention, however, the spring element is held at this hole without any screw connection, only by inserting and expanding the spring element. As shown in FIG. 5, the shorter leg 20 spreads relative to the longer leg 10, with an upper edge of the shorter leg 20 cutting into the material of the inner wall of the hole. This incision alone ensures that the spring element does not can be pulled out of the hole against the direction of insertion.

Das das Loch umgebende Material des Leuchtengehäuses ist metallisch, vorzugsweise Aluminium, um eine ausreichende Leitfähigkeit zum Erdungsleiter des Federelements herzustellen. Aluminium ist auch entsprechend weich, so dass ein Einschneiden des Federelements in die Innenwand des Lochs ermöglicht wird. Insbesondere bei härteren Metallen ist jedoch bevorzugt, dass auch eine Oberflächentexturierung in der Innenwand des Lochs vorgesehen ist. Beispielsweise können ein einfaches Gewinde oder andere sich radial erstreckende Riefen in dem Loch vorgesehen sein, so dass der Reibwiderstand zwischen dem Federelement und der Innenwand des Lochs erhöht wird. Durch das Einschneiden der scharfkantigen Seite von wenigstens einem Schenkel des Federelements in die Innenwand des Lochs 100 wird ferner ein ausreichend niedrigohmiger Kontakt zwischen dem Leuchtengehäuse und dem Federelement gebildet.The material of the light housing surrounding the hole is metallic, preferably aluminum, in order to produce sufficient conductivity to the grounding conductor of the spring element. Aluminum is also correspondingly soft, so that it is possible for the spring element to cut into the inner wall of the hole. In the case of harder metals in particular, however, it is preferred that surface texturing is also provided in the inner wall of the hole. For example, a simple thread or other radially extending grooves can be provided in the hole, so that the frictional resistance between the spring element and the inner wall of the hole is increased. By cutting the sharp-edged side of at least one leg of the spring element into the inner wall of the hole 100, a sufficiently low-resistance contact is also formed between the lamp housing and the spring element.

Zahlreiche Abwandlungen der vorhergehend beschriebenen bevorzugten Ausführungsform sind im Rahmen der Erfindung, die durch die Ansprüche definiert ist, möglich. Beispielsweise kann das Federelement in einem oder mehreren der Schenkel eine ausgestanzte Zunge aufweisen, die bezogen auf die Mittelsenkrechte durch das Loch nach außen aufgebogen ist. Die Zunge kann sich mit einer Kante oder einer Spitze ebenso in der Innenwand des Lochs verkeilen. Beispielsweise kann der längere Schenkelabschnitt, welcher in der vorhergehend dargestellten bevorzugten Ausführungsform der Figuren nur an der Innenwand des Lochs flächig anliegt, zusätzlich zur Halterung der Feder eine entsprechende Zunge aufweisen.Numerous modifications of the preferred embodiment described above are possible within the scope of the invention, which is defined by the claims. For example, the spring element can have a punched-out tongue in one or more of the legs, which tongue is bent outward through the hole in relation to the perpendicular through the hole. The tongue can also wedge itself with an edge or a point in the inner wall of the hole. For example, the longer leg section, which in the preferred embodiment of the figures presented above, rests flat only on the inner wall of the hole, can have a corresponding tongue in addition to holding the spring.
