Description

Schnappscheibenschalter mit BefestigungselementSnap disc switch with fastener
Die Erfindung betrifft einen Schnappscheibenschalter nach dem Oberbegriff des Anspruchs 1 mit einer gewölbten Schnappscheibe, welche über wenigstens zwei Aufla- geelemente auf einem Grundelement abgestützt ist.The invention relates to a snap disk switch according to the preamble of claim 1 with a domed snap disk which is supported on a base element via at least two support elements.
Derartige Schnappscheibenschalter sind im Stand der Technik hinlänglich bekannt und werden überwiegend im Bereich von Tastaturen verwendet. Da einer der Schaltkontakte regelmäßig auf der Schnappscheibe angeordnet ist und sich der ent- sprechende Gegenkontakt auf dem Grundelement befindet, ist es erforderlich, die Schnappscheibe in ihrer Position zu fixieren. Dies geschieht regelmäßig dadurch, daß die Schnappscheibe innerhalb einer Vertiefung angeordnet ist oder um die Schnappscheibe entsprechende Begrenzungen angebracht sind. Denn konstruktionsbedingt können die Auflageelemete nicht fest mit dem Grundelement verbunden sein, da die Auflageelemente beim Betätigen der Schnappscheibe eine geringe Bewegung ausführen. Eine Befestigung der Auflageelemente auf dem Grundelement würde die Funktion der Schnappscheibe daher stark beeinträchtigen und wegen der auf die Befestigung wirkenden Kräfte nicht dauerhaft haltbar sein. Es ist Aufgabe der Erfindung einen eingangs genannten Schnappscheibenschalter derart auszubilden, daß die Schnappscheibe auf einfache Weise auf dem Grundelement fixierbar ist.Such snap disk switches are well known in the prior art and are mainly used in the field of keyboards. Since one of the switch contacts is regularly arranged on the snap disk and the corresponding mating contact is on the base element, it is necessary to fix the snap disk in its position. This happens regularly in that the snap disk is arranged within a recess or appropriate limits are placed around the snap disk. Because of the design, the support elements cannot be firmly connected to the base element, since the support elements make a slight movement when the snap disk is actuated. Fastening the support elements on the base element would therefore seriously impair the function of the snap disk and would not be durable due to the forces acting on the fastening. It is an object of the invention to design a snap disk switch mentioned at the outset in such a way that the snap disk can be fixed in a simple manner on the base element.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des kennzeichnenden Teils des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved from the features of the characterizing part of claim 1. Advantageous further developments of the invention result from the subclaims.
Gemäß der Erfindung weist wenigstens ein Auflageelement ein Befestigungselement auf, mittels dem die Schnappscheibe auf dem Grundelement fixierbar ist. Durch das Befestigungselement kann in vorteilhafter Weise erreicht werden, daß das Auflageelement im geringen Maße beweglich mit dem Grundelement verbunden ist. Das Auflageelement kann somit die durch die Betätigung der Schnappscheibe verursachte Bewegung durchführen. Da die vom Auflageelement vorgenommene Bewegung im wesentlichen eine Torsionsbewegung ist, verbleibt die Schnappscheibe in ihrer Position. Weiter Maßnahmen zur Fixierung der Schnappscheibe auf dem Grundelement sind nicht mehr erforderlich.According to the invention, at least one support element has a fastening element, by means of which the snap disk can be fixed on the base element. By means of the fastening element it can advantageously be achieved that the support element is movably connected to the base element to a small extent. The support element can thus carry out the movement caused by the actuation of the snap disk. Since the movement made by the support element is essentially a torsional movement, the snap disc remains in its position. Further measures for fixing the snap disk on the base element are no longer necessary.
In vorteilhafter Weise ist das Befestigungselement über Ausgleichsstege mit dem Auflageelement verbunden. Durch die Ausgleichsstege wird die Torsionsbewegung des Auflageelements abgefedert, so daß auf das Befestigungselement nur noch eine sehr geringe Torsionskraft wirkt. Da die Größe der Torsionskraft abhängig von der Ausgestaltung der Ausgleichsstege ist, müssen die Ausgieichsstege so dimensioniert werden, daß ein Optimum zwischen der Torsionskraft, die auf die Befesti- gungselemente wirkt, und der Kraft, mit welcher die Schnappscheibe in ihrer Position gehalten wird, besteht. Sind die Ausgleichsstege zu schwach dimensioniert, ist die Torsionskraft, die auf die Befestigungselemente wirkt, zwar sehr gering, jedoch besteht die Gefahr, daß die Schnappscheibe nicht in ihrer genauen Lage gehalten wird, da sich die Ausgleichsstege durchbiegen könnten. Die Ausgleichsstege dürfen aber auch nicht zu stark dimensioniert sein, da zum einen dann die auf die Befestigungselemente wirkenden Torsionskräfte zu groß sind und auch eine lineare Bewegung der Auflageelemente nicht mehr möglich ist. Dies wäre nachteilig, da, wenngleich auch die Auflageelemente im wesentlichen eine Torsionsbewegung durchfüh- ren, die Auflageelemente bei der Betätigung der Schnappscheibe auch eine geringe lineare Bewegung durchführen.The fastening element is advantageously connected to the support element via compensating webs. The torsion movement of the support element is cushioned by the compensating webs, so that only a very low torsional force acts on the fastening element. Since the magnitude of the torsional force depends on the design of the compensating webs, the compensating webs must be dimensioned so that there is an optimum between the torsional force acting on the fastening elements and the force with which the snap disk is held in position . If the compensating webs are dimensioned too weakly, the torsional force acting on the fastening elements is very small, but there is a risk that the snap disk will not be held in its exact position, since the compensating webs could bend. However, the compensating webs must also not be dimensioned too strongly, since on the one hand the torsional forces acting on the fastening elements are too great and a linear movement of the support elements is no longer possible. This would be disadvantageous since, although the support elements also essentially perform a torsional movement. ren, the support elements also perform a slight linear movement when the snap disk is actuated.
Bei einer weiteren besonderen Ausführungsform der Erfindung ist vorgesehen, daß das Befestigungselement eine Fläche aufweist, welche mittels der sogenannten SMD-Technik befestigbar ist. Hierdurch läßt sich die Schnappscheibe in vorteilhafter Weise sehr rationell auf dem Grundelement anbringen.In a further special embodiment of the invention it is provided that the fastening element has a surface which can be fastened by means of the so-called SMD technology. In this way, the snap disk can advantageously be attached very efficiently to the base element.
Das Befestigungselement kann aber auch einen Steckfuß aufweisen, mittels dem es in einer Öffnung befestigbar ist. Eine derartige Ausführungsform ist dann besonders vorteilhaft, wenn die Schnappscheibe auf einer Leiterplatte befestigt werden soll.The fastening element can also have a plug-in foot, by means of which it can be fastened in an opening. Such an embodiment is particularly advantageous when the snap disk is to be attached to a printed circuit board.
Besonders vorteilhaft ist es, wenn die Schnappscheibe und das Befestigungselement gegebenenfalls mit dem Steckfuß einstückig ausgebildet ist, wie dies bei einer weiteren besonderen Ausführungsform der Erfindung vorgesehen ist.It is particularly advantageous if the snap disk and the fastening element are optionally formed in one piece with the plug-in foot, as is provided in a further special embodiment of the invention.
Weitere Merkmale der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines besonderen Ausführungsbeispiels unter Bezugnahme auf die Zeichnung.Further features of the present invention result from the following description of a particular exemplary embodiment with reference to the drawing.

Wie den Figuren 1 und 2 entnommen werden kann, weist eine gewölbte Schnappscheibe 1 eines Schnappscheibenschalters im höchsten Punkt der Wölbung einen Schaltkontakt 10 auf. Der Schaltkontakt 10 ist als kugelförmige Wölbung ausgebildet, welche sich in radialer Richtung der Schnappscheibe nach innen erstreckt.As can be seen from FIGS. 1 and 2, a curved snap disk 1 of a snap disk switch has a switch contact 10 at the highest point of the curvature. The switch contact 10 is designed as a spherical curvature which extends inwards in the radial direction of the snap disk.
Die Schnappscheibe 1 liegt mittels vier Auflageelemente 2, 3, 4, 5 auf einem Grundelement 6 auf. Die Auflageelemente 2, 3, 4, 5 sind als Abbiegung des entsprechen- den Teils der Schnappscheibe 1 ausgebildet. Ausgehend von einem Auflageelement 2 erstreckt sich ein laschenförmiges Befestigungselement 7. Das Befestigungselement 7 besteht im wesentlichen aus zwei ebenen Flächenelementen, welche so ausgebildet sind, daß sie mittels der sogenannten SMD-Technik befestigbar sind. Die Flächenelemente 7 sind über schmale Stege 8 einstückig mit dem Auflageele- ment 2 verbunden.The snap disc 1 rests on a base element 6 by means of four support elements 2, 3, 4, 5. The support elements 2, 3, 4, 5 are designed as a bend in the corresponding part of the snap disc 1. Starting from a support element 2, a tab-shaped fastening element 7 extends. The fastening element 7 essentially consists of two flat surface elements which are designed such that they can be fastened by means of the so-called SMD technology. The surface elements 7 are connected in one piece to the support element 2 via narrow webs 8.
Wird auf die Schnappscheibe 1 Druck ausgeübt, üben die Auflageelemente 2, 3, 4, 5 unter anderem eine Drehbewegung aus. Die Bewegung des Auflageelements 2 wird von den Verbindungsstegen 8 im wesentlichen federnd aufgefangen, so daß auf die Flächenelemente 7 eine sehr geringe Restkraft übertragen wird. Durch die geringe Kraft, die auf die Flächenelemente 7 übertragen wird, wird eine sehr große Haltbarkeit der Befestigungselemente 7 erreicht. Die Schnappscheibe 1 wird durch die Befestigungselemente 7 in ihrer Position festgehalten.If pressure is exerted on the snap disk 1, the support elements 2, 3, 4, 5 exert, among other things, a rotary movement. The movement of the support element 2 is absorbed essentially resiliently by the connecting webs 8, so that a very low residual force is transmitted to the surface elements 7. The low force that is transmitted to the surface elements 7 means that the fastening elements 7 have a very long service life. The snap disk 1 is held in position by the fastening elements 7.
In den Figuren 3 und 4 ist eine zweite Ausführungsform einer erfindungsgemäßen Schnappscheibe dargestellt. Gleiche Elemente sind mit gleichen Bezugszeichen versehen; zur Unterscheidung sind die Bezugszeichen lediglich mit einem Strich versehen. Gegenüber der ersten Ausführungsform weisen die beiden flächigen Ele- mente T jeweils einen Steckfuß 9' auf. Die Steckfüße 9' erstrecken sich in die der Schnappscheibe V abgewandte Richtung und sind einstückig mit den Flächenelementen T als gebogenes Blechteil ausgebildet. Die Steckfüße 9' sind sehr gut geeignet zur Befestigung der Schnappscheibe 1' auf einer Leiterplatte. Hierzu muß die Leiterplatte lediglich Bohrungen aufweisen, in die die Steckfüße 9' eingesteckt werden.3 and 4 show a second embodiment of a snap disk according to the invention. The same elements are provided with the same reference symbols; to distinguish them, the reference symbols are simply provided with a dash. Compared to the first embodiment, the two flat elements elements T each on a plug-in foot 9 '. The plug feet 9 'extend in the direction facing away from the snap disc V and are formed in one piece with the surface elements T as a bent sheet metal part. The plug-in feet 9 'are very suitable for fastening the snap disk 1' on a circuit board. For this purpose, the circuit board only has to have bores into which the plug-in feet 9 'are inserted.
In den Figuren 5 bis 7 ist eine weitere Ausführungsform einer erfindungsgemäßen Schnappscheibe dargestellt; gleiche Elemente sind mit gleichen Bezugszeichen ver- sehen; zur Unterscheidung sind die Bezugszeichen jedoch mit zwei Strichen versehen.FIGS. 5 to 7 show a further embodiment of a snap disk according to the invention; identical elements are provided with the same reference symbols; to distinguish them, however, the reference symbols are provided with two dashes.
Die in den Figuren 5 bis 7 dargestellte Schnappscheibe unterscheidet sich von den zuvor beschriebenen Schnappscheiben dadurch, daß die Auflageelemente 2", 3", 4", 5" nicht gleichmäßig am Umfang der Schnappscheibe 1 " verteilt angeordnet sind sondern paarweise gegenüberliegend angeordnet sind. Jeweils zwei Auflageelemente 2", 3" beziehungsweise 4", 5" erstrecken sich in die selbe Richtung. Hierdurch bedingt ist für jedes Paar der Auflageelemente 2", 3", 4", 5" ein flächiges Element 7" vorhanden. Das flächige Element 7" ist über etwa s-förmig verlaufende Stege 8" mit den Auflageelementen 2", 3", 4", 5" verbunden.The snap disk shown in FIGS. 5 to 7 differs from the snap disks described above in that the support elements 2 ", 3", 4 ", 5" are not arranged evenly distributed over the circumference of the snap disk 1 "but are arranged in pairs opposite one another two support elements 2 ", 3" and 4 ", 5" extend in the same direction. As a result, for each pair of support elements 2 ", 3", 4 ", 5" there is a flat element 7 ". The flat element 7 "is connected to the support elements 2", 3 ", 4", 5 "via approximately S-shaped webs 8".
Durch die besondere Form der Verbindungsstege 8" lassen sich geradlinige Bewegungen der Auflageelemente 2", 3" besonders gut ausgleichen. Hierdurch ist es möglich, daß auch die gegenüberliegenden Auflageelemente 4", 5" über Verbin- dungsstege 8" mit einem weiteren flächigen Element 7" verbunden sind. The special shape of the connecting webs 8 "makes it particularly easy to compensate for linear movements of the support elements 2", 3 ". This makes it possible for the opposite support elements 4", 5 "to be connected to a further flat element 7 via connecting webs 8" " are connected.
