Elastische Kontaktzunge und Verfahren zu ihrer Herstel¬ lung aus einer Metallplatte Elastic contact tongue and method for its manufacture from a metal plate
BeschreihnnpDescriptive
Die Erfindung betrifft eine elastische, flexible Kontaktzunge und den Arbeitsvorgang, mit der diese aus einer Metallplatte gewonnen wird, und von der sie heraussteht, um im Arbeitseinsatz mit einer anderen Platte und/oder mit anderen Gegenständen, die sich in ihrer Nähe befinden, einen mechanischen oder elektrischen Kontakt herzustellen. Es sind flexible und elastische Kontaktzungen aus Metall bekannt, durch die ein elektrischer oder mechanischer Kontakt zwischen denThe invention relates to an elastic, flexible contact tongue and the process by which it is obtained from a metal plate and from which it protrudes in order to work mechanically with another plate and / or with other objects that are in its vicinity or make electrical contact. Flexible and elastic metal contact tongues are known, through which an electrical or mechanical contact between the

Die andere Extremität bleibt frei, und steht im Arbeitseinsatz hervor, bis die zu kontaktierende Oberfläche berührt wird.The other extremity remains free and protrudes during work until the surface to be contacted is touched.
In einem zweiten Fall wird die Kontaktzunge direkt aus derIn a second case, the contact tongue is directly from the
Metallplatte gewonnen, von der sie heraussteht, und zwar durch einen Arbeitsvorgang, der aus einer Folge von Stanz- undMetal plate from which it protrudes, by a process that consists of a sequence of stamping and
Fi gurau sschnitts-Arbeitsgängen besteht, einer teilweisen , lokalisierten Prägung, und einer Biegung.Fi gurau cut operations consists of a partial, localized embossing, and a bend.
Bei den Figurausschnitts-Arbeitsvorgängen wird das Metall so entfernt, daß eine Zunge gebildet wird, die an einer Extremität mit der Platte verbunden bleibt, und an drei Seiten freisteht.In the figure-cutting operations, the metal is removed so that a tongue is formed which remains connected to the plate at one extremity and is free on three sides.
Aus dem Vorgang der lokalisierten, teilweisen Prägung inFrom the process of localized, partial embossing in
Korrespondenz zu dem mit der Platte verbundenen Teil erfolgt, daß die hervorstehende Zunge elastische Eigenschaften aufweist.Correspondence to the part connected to the plate is that the protruding tongue has elastic properties.
Mit dem Biegevorgang des Plättchen wird dieses in Form einerWith the bending process of the plate this is in the form of a
Zunge fassoniert, und dem Arbeitsziel entsprechend gebogen, bis es von der Platte, aus der es gewonnen wurde, dermaßen hervorsteht, daß es den Kontakt im gewünschten Punkt mit einer anderen Platte oder einem anderen zu kontaktierenden Element zustande bringt. Die bekannten Zungen und Arbeitsvorgänge, mit denen diese hergestellt werden, weisen einige Nachteile auf.Tongue shaped and bent according to the work objective until it protrudes from the plate from which it was obtained to such an extent that it makes contact with another plate at the desired point or another element to be contacted. The known tongues and operations with which they are made have some disadvantages.
Die Zunge des ersten Typs muß eigens hergestellt werden, erst danach erfolgt ihre Positionierung auf der Platte, auf der sie dann, durch festgelöten, oder, wie es häufiger geschieht, mit Bohrloch versehen und festgenietet, oder per Einschnappen, befestigt werden muß .The tongue of the first type has to be specially manufactured, only then is it positioned on the plate, on which it then has to be soldered, or, as is more frequently the case, drilled and riveted, or snapped into place.
A ußer dem komplexen H erstell u ng s v organg , u nd der darauffolgenden Positionierung und Befestigung, steht die Zunge auch völlig von der Platte, auf der sie befestigt ist, hervor, so daß sie während und nach der Montage anschlagen, und damit auf Grund ihrer geringen Stärke beschädigt werden, oder durch ihre scharfen Kanten Personen, die mit ihr hantieren, Verletzungen beibringen kann.In addition to the complex process and the subsequent positioning and fastening, the tongue also protrudes completely from the plate on which it is fastened, so that it strikes during and after assembly, and therefore on the ground its low strength, or its sharp edges can cause injury to people handling it.
Die Kontaktzunge des zweiten Typs wird direkt mittels eines traditionellen Stanz-Figurausschnitt-Arbeitsganges aus der Platte gewonnen, auf der sie zum Einsatz kommt, und der eine relativ große Öffnung um die Zunge herum schafft, welche jedoch bei einigen Anwendungen aus Platzgründen sehr dünn, und daher schwach ausfällt.The contact tongue of the second type is obtained directly from the plate on which it is used, by means of a traditional punch-figure cutting operation, and which creates a relatively large opening around the tongue, which in some applications is very thin, however, for reasons of space therefore turns out weak.
Der große Zwischenraum an den drei Seiten der Kontaktzunge führt einerseits zur Verhakung der vorstehenden Zunge mit Fremdkörpern und Verletzungen an den Händen des Beschäftigten, andererseits stellt sie eine Ausgangs- und Auslaßöffnung dar, die bei einigen Anwendungen nicht akzeptabel ist. Außerdem kann die durch die Stanzung hervorgerufene offenen Kante bei ungeschicktem Hantieren zu Verletzungen der Bedienungsperson führen.The large space on the three sides of the contact tongue leads on the one hand to the hooking of the protruding tongue with foreign bodies and injuries on the hands of the employee, on the other hand it represents an outlet and outlet opening, the is not acceptable in some applications. In addition, the open edge caused by the punching can lead to injuries to the operator if the handling is unskillful.
Ziel der vorliegenden Erfindung ist es, eine elastische Kontaktzunge zu schaffen, die von einer Metallplatte hervorsteht, die preisgünstig und schnell herzustellen ist, und derart ausgebildet, daß sie sowohl den Kontakt mit einer anderen Metallplatte oder einem anderen metallischen Element garantiert, als auch die Beibehaltung ihrer Eigenschaften während der Produktionsphase und nach ihrer Vermarktung, auch wenn diese ohne besondere Vorkehrungen und Rücksichtnahmen durchgeführt werden. Ein anderes Ziel ist es, die Sicherheit der Bedienungsperson zu gewährleisten, die durch das Hervorstehen der Zunge und deren feiner Struktur keine Handverletzungen erleiden darf.The aim of the present invention is to provide an elastic contact tongue which projects from a metal plate, which is inexpensive and quick to produce, and which is designed in such a way that it guarantees both the contact with another metal plate or another metallic element, as well as the retention their properties during the production phase and after their marketing, even if these are carried out without special precautions and considerations. Another aim is to ensure the safety of the operator, who must not suffer hand injuries due to the protrusion of the tongue and its fine structure.
Ein weiteres Ziel ist es, eine Kontaktzunge zu schaffen, die so gut wie keine Hohlräume oder Öffnungen freiläßt, um dadurch das Durchtreten von Wellen, Objekten oder Körpern zu verhindern. Die Erfindung, die genannte Resultate ermöglicht, besteht aus einer Kontaktzunge, die aus der Platte, aus der sie herausragen soll, mittels eines ersten Stanzarbeitsganges gewonnen wird, durch den die Ausgangsöffnung geschaffen wird, eines Prägearbeitsganges, mit dem innerhalb des Stanzloches (das dadurch teilweise wieder geschlossen wird) eine Prägung und ein hervorstehender Kontaktknopf geschaffen wird, eines zweiten Stanzarbeitsganges längs der Endlinien der Zunge, der von der der Prägung gegenüberliegenden Seite aus durchgeführt wird, und einer Biegung bis zum Herausstehen der Zunge von der Oberfläche der Platte. Die Erfindung weist folgende Vorteile auf:Another goal is to create a contact tongue that leaves virtually no voids or openings, thereby preventing the passage of waves, objects or bodies. The invention, which enables the results mentioned, consists of a contact tongue, which is obtained from the plate from which it is to protrude, by means of a first stamping operation, through which the exit opening is created, an embossing operation, with which inside the stamping hole (which in part is thereby is closed again) an embossing and a protruding contact button is created, a second stamping operation along the end lines of the tongue, which is carried out from the side opposite the embossing, and a bend until the tongue protrudes from the surface of the plate. The invention has the following advantages:
- auf der Kontaktzunge befindet sich ein vorstehender, rundlicher Kontaktknopf, der einen guten elastischen Kontakt mit anderen in der Nähe befindlichen metallischen Elementen gewährleistet, gleichzeitig schließt seine Anwesenheit eine Verletzungsmöglichkeit von Personen aus, die mit der Platte hantieren;- On the contact tongue there is a protruding, round contact button, which ensures good elastic contact with other nearby metallic elements, at the same time its presence precludes the possibility of injury to people handling the plate;
- die verdichtete Kontaktzunge ragt aus der Oberfläche der Metallplatte, aus der sie gewonnen wurde, derart hervor, daß sie sich, wenn sie von der Gegenseite eingedrückt wird, in die durch den Prägearbeitsgang geschaffene Prägung hineinbiegt, und damit im Bedarfsfall flach auf der Platte anliegt;- The compressed contact tongue protrudes from the surface of the metal plate from which it was obtained in such a way that, when it is pressed in from the opposite side, it bends into the embossing created by the embossing process, and thus lies flat on the plate if necessary ;
- die Kontaktzunge zeigt mit der scharfen Kante, die in der zweiten Stanzphase entsteht, gegen das Innere der Prägung, und somit in eine vor der Bedienungsperson geschützte Richtung, so daß Verletzungen vermieden werden;- The contact tongue points with the sharp edge, which arises in the second stamping phase, towards the inside of the embossing, and thus in a direction protected from the operator, so that injuries are avoided;
- die um die Kontaktzunge herum bestehenden Öffnungen sind minimal, und werden bei Einbiegen der Zunge in die Prägeöffnung fast völlig verschlossen.- The openings around the contact tongue are minimal and are almost completely closed when the tongue is bent into the embossing opening.
Die Kontaktzunge ist durch ihre Biegefähigkeit in die Prägeöffnung hinein, durch ihren hervorstehenden Kontaktpunkt in Knopfform, durch ihr normalerweise begrenztes Hervorstehen von der Platte hervor, und durch die Tatsache, daß die scharfen Kanten der Stanzungen versteckt, und von der Bedienungsperson unerreichbar sind, sicher in Funktion und Handhabung, und daher von Vorteil im Hinblick auf den aktuellen Stand der Technik.The contact tongue is characterized by its ability to bend into the embossing opening, by its protruding contact point in the form of a button, by its normally limited protrusion from the plate, and by the fact that the sharp edges of the Die cuts are hidden, and are inaccessible to the operator, safe in function and handling, and therefore advantageous in terms of the current state of the art.
Die Kontaktzunge wird im Folgenden detailliert mit Hilfe der Zeichnungen beschrieben, die sowohl die bevorzugte Form ihrer Realisierung aufzeigen, als auch die Arbeitsgänge, mit denen sie hergestellt wird. Hierbei zeigt:The contact tongue is described in detail below with the aid of the drawings, which show both the preferred form of its implementation and the operations with which it is produced. Here shows:

- Figur 6 zeigt den Schnitt durch zwei gegeneinanderliegende Platten mit Kontakt durch die elastische, flexible Kontaktzunge, die aus einer der beiden Platten hervorsteht. Die Zeichnungen und die entsprechend beschriebenen Teile sind nur zu Illustrationszwecken der Erfindung genannt worden, und stellen in keinem Fall eine Begrenzung derselben dar.- Figure 6 shows the section through two opposing plates with contact thanks to the elastic, flexible contact tongue that protrudes from one of the two plates. The drawings and the correspondingly described parts have been mentioned for the purpose of illustration of the invention only and in no way represent a limitation thereof.
In den Zeichnungen wurde mit 1 die Grundplatte bezeichnet, mit 2 die flexible Kontaktzunge, mit 3 die Kante, die die Prägung 4 begrenzt, mit 5 der hervorstehende Kontaktknopf, mit 6 die Öffnung für den Auswurf des während der Prägephase verdichteten Materials, mit 8 das freie Ende der Kontaktzunge 2, mit 9 die obere Oberfläche der Platte 1 , mit 10 die untere Oberfläche, mit 1 1 der gepreßte Rand zwischen der Kante 3 der Prägung 4 und der umlaufenden Kante der Kontaktzunge 2. Die Erfindung besteht also aus einer besonderen Struktur und Formation der flexiblen und elastischen Kontaktzunge 2, die von einer Platte 1 gewonnen, oder geformt und/oder strukturiert wird, deren Teil sie ist.In the drawings, 1 denotes the base plate, 2 the flexible contact tongue, 3 the edge that defines the embossing 4, 5 the protruding contact button, 6 the opening for the ejection of the material compacted during the embossing phase, 8 the free end of the contact tongue 2, with 9 the upper surface of the plate 1, with 10 the lower surface, with 1 1 the pressed edge between the edge 3 of the embossing 4 and the peripheral edge of the contact tongue 2. The invention therefore consists of a special structure and formation of the flexible and elastic contact tongue 2, which is obtained from a plate 1, or shaped and / or structured, of which it is part.
Die Erfindung besteht weiterhin aus den besonderen Arbeitsgängen, mit denen die Kontaktzunge 2 hergestellt wird, die fester Bestandteil der Platte 1 ist. Die Kontaktzunge steht von der Platte 1 hervor, und hat elastische Eigenschaften, die sich insofern auswirken, als daß sich die Zunge, wenn sie gegen Fremdkörper gedrückt wird, biegt, den Kontakt hält, und gleichzeitig in Richtung der Vertiefung der Prägung 4 gedrückt wir, aus der sie normalerweise bis zu ihrem Hereindrücken hervorsteht, das, falls notwendig, vollständi g durchgeführt werden kann, so daß gleichzeitig die Öffnung, aus der die Zunge 2 entstanden ist, fast vollständig verschlossen wird.The invention also consists of the special operations with which the contact tongue 2 is produced, which is an integral part of the plate 1. The contact tongue protrudes from the plate 1 and has elastic properties which have the effect that the tongue, when pressed against foreign bodies, bends, keeps the contact and at the same time is pressed in the direction of the depression of the embossing 4, out of it normally protrudes up to its pushing in, which, if necessary, can be carried out completely, so that at the same time the opening from which the tongue 2 is formed is almost completely closed.
Die Arbeitsgänge zur Herstellung der Kontaktzunge sehen eine erste Stanzphase vor (Figur 3), mit der auf der Platte 1 eine weite Ausstoßöffnung 6 geschaffen wird, eine Prägephase (Figur 4), durch die an den Kanten der Ausstoßöffnung 6 die Prägung 4 und der hervorstehende Kontaktknopf 5 geschaffen werden, eine zweite Stanz- und Biegephase, in der das Metall, mit reduziertem Durchmesser und in der Prägung 4 verdichtet, entlang der Linie, die den Umfang der Kontaktzunge 2 bestimmt, gestanzt, und auf der Seite herausgedrückt wird, von der die Prägung 4 selbst durchgeführt wurde.The operations for producing the contact tongue provide for a first stamping phase (FIG. 3), with which a wide ejection opening 6 is created on the plate 1, an embossing phase (FIG. 4), through which the embossing 4 and the protruding edge are formed on the edges of the ejection opening 6 Contact button 5 are created, a second stamping and bending phase, in which the metal, with reduced diameter and in the embossing 4, punched along the line that defines the circumference of the contact tongue 2, and is pressed out on the side from which embossing 4 was carried out itself.
Mit dem ersten Stanzarbeitsgang wird Metall entfernt, und die Ausstoßöffnung 6 geschaffen, die von normalerweise länglicher Form ist, und in Korrespondenz zur zu produzierenden Zentralachse der Kontaktzunge 2 liegt.The first stamping operation removes metal and creates the ejection opening 6, which is normally elongated in shape and is in correspondence with the central axis of the contact tongue 2 to be produced.
Mit dem darauf folgenden Prägearbeitsgang wird das gesamte Metall der Prägung 4 unter Druck verformt und verdichtet, bis es derart elastisch ist, daß die realisierte Kontaktzunge um ihre Ruheposition herum flexibel und elastisch wird, während die Stärke der Platte 1 lokal begrenzt reduziert ist. In dieser Phase wird eine Verlagerung des Metalls bewirkt, das sich zur Öffnung 6 hin bewegt, die sich dadurch verengt, weshalb sie anfangs so dimensioniert sein muß, daß eine Verdichtung, und damit die Verwirklichung der gewünschten Pressung 4, gewährleistet wird. Die Tiefe der Pressung beträgt normalerweise etwa die Hälfte der Originalstärke der Platte 1 , um dem Endprodukt der Kontaktzunge 2 zu erlauben, sich einzubiegen, wenn sie gedrückt wird, bis sie die Pressung selbst ausfüllt, und ohne von der Oberfläche 9 der Platte hervorzuragen, und ohne in die Form, aus der sie während der zweiten Stanzung hervorgegangen ist, zurückzuschnappen, und darin festgehalten zu werden.With the subsequent embossing operation, the entire metal of the embossing 4 is deformed and compressed under pressure until it is so elastic that the contact tongue realized becomes flexible and elastic around its rest position, while the thickness of the plate 1 is reduced locally to a limited extent. In this phase, a shift of the metal is effected, which moves towards the opening 6, which thereby narrows, which is why it is initially so must be dimensioned so that compression, and thus the realization of the desired pressure 4, is ensured. The depth of the pressure is normally about half the original thickness of the plate 1 to allow the end product of the contact tongue 2 to bend when pressed until it fills the pressure itself and without protruding from the surface 9 of the plate, and without snapping back into the shape from which it emerged during the second punching and without being held in it.
Während des Preßarbeitsvorgangs wird also die Verdünnung der Platte 1 in Korrespondenz zur Prägung 4 erreicht, sowie in reduzierter Form in dem Punkt, zu dem sich auf Grund einer Kavität auf dem Prägestempel das Metall hin verlagert, damit auf der Kontaktzunge 2 der Kontaktknopf 5 geschaffen wird, der dem Kontakt der Zunge selbst mit anderen Körpern dient. Die Prägung 4 wird in größeren Dimensionen (Länge, Breite) realisiert, als die der zu produzierenden flexiblen Kontaktzunge 2, indem sich die Linie, auf der die Prägung für die Kontaktzunge gestanzt wird, im Inneren der Kante 3 befindet, die die Prägung 4 begrenzt, so daß auf diese Weise die Krone 1 1 mit reduzierter Stärke entsteht.During the pressing operation, the thinning of the plate 1 is achieved in correspondence with the embossing 4, and in a reduced form at the point to which the metal shifts due to a cavity on the stamping die, so that the contact button 5 is created on the contact tongue 2 which serves the contact of the tongue itself with other bodies. The embossing 4 is realized in larger dimensions (length, width) than that of the flexible contact tongue 2 to be produced, in that the line on which the embossing for the contact tongue is punched is located inside the edge 3, which delimits the embossing 4 , so that the crown 1 1 is created with reduced strength.
Der Prägestempel, der die Prägung 4 prägt, soll einen Prägekopf aufweisen, der derart gestaltet ist, daß der Boden der Prägung 4, außer dem vorstehenden Kontaktknopf 5, in gleichmäßiger Stärke ausgeführt wird, wenn eine Zunge gewünscht wird, die auf ihrer gesamten Länge eine konstante Biegefähigkeit aufweisen soll. Der Prägestempel soll hingegen einen geformten Kopf zur Prägung einer nicht einheitlichen Vertiefung aufweisen, wenn eine Kontaktzunge mit größerer Biegefähigkeit geschaffen werden soll, die in der Lage ist, sich je nach den auf ihrer Länge befindlichen Elementen unterschiedlich zu biegen, so daß eine Kontaktzunge mit minimaler Stärke in Korrespondenz der Punkte entsteht, in der sie die größere Biegekapazität aufweisen soll.The embossing stamp which embosses the embossing 4 is intended to have an embossing head which is designed in such a way that the bottom of the embossing 4, apart from the above contact button 5, is of uniform thickness if a tongue is desired which is on it entire length should have a constant bendability. The stamp, on the other hand, should have a shaped head for embossing a non-uniform recess if a contact tongue with greater flexibility is to be created, which is able to bend differently depending on the elements located along its length, so that a contact tongue with minimal Strength arises in the correspondence of the points in which it should have the greater bending capacity.
Die Kontaktzunge 2 wird also auf Grund der Stanzung von drei Seiten der Prägung 4 geschaffen, und resultiert damit als eine einseitig befestigte Struktur. Ihre Stanzung erfolgt mittels eines Prägestempels, der von Seite 10 der Platte 1 aus eingesetzt wird, auf der Rückseite der Prägung 4, so daß die scharfe Kante der Kontaktzunge 2 zur Prägung 4 hin ausgerichtet ist, und die scharfe Kante der Platte 1 im Inneren der Prägung 4 verbleibt. Im Falle einer Kontaktzunge 2 mit wenig geringeren Abmessungen als die Prägung 4, wenn also die Krone 1 1 nur eine minimale Breite aufweist, ist während des Stanzvorgangs nicht unbedingt ein der Grundform genau entsprechender Prägestempel notwendig. Beim Stanzvorgang wird die Kontaktzunge gegen die Außenseite der Platte 1 gedrückt, ihr Ansatzpunkt bleibt verbunden mit dem Rand der Vertiefung, aus der die Zunge gebildet wurde, und verbleibt in der gewünschten Ruheposition, aus der wenigstens ihr Kontaktknopf 5 aus der Oberfläche 9 herausragt. Der scharfe Rand der Kontaktzunge 2 bleibt somit von der Materialstärke der Platte 1 geschützt, so daß der Kontakt zwischen scharfem Rand und Bedienungsperson verhindert wird, während die Öffnung von kleiner Abmessung bleibt, und durch das Hineindrücken der Zunge gegen die Prägung 4 fast völlig verschlossen wird.The contact tongue 2 is thus created on the basis of the stamping from three sides of the embossing 4, and thus results as a structure fastened on one side. They are stamped by means of an embossing stamp which is inserted from page 10 of plate 1 on the back of embossing 4, so that the sharp edge of contact tongue 2 is aligned with embossing 4, and the sharp edge of plate 1 inside the Embossing 4 remains. In the case of a contact tongue 2 with slightly smaller dimensions than the embossing 4, that is to say if the crown 11 has only a minimal width, an embossing stamp which corresponds exactly to the basic shape is not absolutely necessary during the stamping process. During the stamping process, the contact tongue is pressed against the outside of the plate 1, its starting point remains connected to the edge of the depression from which the tongue was formed, and remains in the desired rest position from which at least its contact button 5 protrudes from the surface 9. The sharp edge of the contact tongue 2 thus remains from the Material thickness of the plate 1 protected, so that the contact between the sharp edge and the operator is prevented while the opening remains small, and is almost completely closed by pressing the tongue against the embossing 4.
Die so strukturierte und geformte Kontaktzunge erscheint also als integrierter Bestandteil der Platte 1 , weist eine längliche zentrale Öffnung von kleiner Abmessung auf, die von der Prägung der Platte 1 herrührt, bei der das geprägte Material teilweise die Originalöffnung 6 ausfüllt, verfügt gegen ihren freistehenden und Rand hin über einen hervorstehenden Knopf 5, und ist gegen das Äußere der Prägung 4 hin orientiert.The thus structured and shaped contact tongue thus appears as an integral part of the plate 1, has an elongated central opening of small dimensions, which results from the embossing of the plate 1, in which the embossed material partially fills the original opening 6, has against its free-standing and Edge over a protruding button 5, and is oriented towards the outside of the embossing 4.
Bei anderen Ausführungen kann die Kontaktzunge 2 an ihrem freistehenden Ende 8 mehr als einen Kontaktknopf 5 aufweisen. Bei wieder anderen Ausführungen kann die Zunge so geformt sein, daß sie bei Seitenansicht derart über die Platte 1 heraussteht, daß ihr Kontakt mit anderen Körpern erleichtert wird, und daher keine hervorstehenden Kontaktknöpfe notwendig sind. In other embodiments, the contact tongue 2 can have more than one contact button 5 at its free-standing end 8. In still other designs, the tongue can be shaped so that it protrudes from the plate 1 when viewed from the side in such a way that its contact with other bodies is facilitated and therefore no protruding contact buttons are necessary.
