Tastatur für KommunikationsendgeräteKeyboard for communication terminals
Die vorliegende Erfindung betrifft eine Tastatur für aus Unterstrich und Oberschale bestehende Kommunikationsendgeräte, wobei in der Oberschale Durchbrüche für die Tasten der Tastatur vorgesehen sind.The present invention relates to a keyboard for communication terminals consisting of underscore and upper shell, openings being provided in the upper shell for the keys of the keyboard.
Bisher wurden als Trägermaterial für die einzelnen Tasten Silikonmatten verwendet. Bei der Verwendung von Silikonmatten ist die Gefahr des Ausreißens von Tasten sehr hoch, da Silikon nicht robust genug ist. Andere Lösungen, bei denen die Tasten beweglich in einem Zusatzbauteil befestigt sind, sind bezüglich der Montage sehr aufwendig und benötigen eine verhältnismäßig hohe Bauhöhe.So far, silicone mats have been used as the carrier material for the individual keys. When using silicone mats, the risk of buttons being torn out is very high, since silicone is not robust enough. Other solutions, in which the keys are movably attached in an additional component, are very complex to assemble and require a relatively high overall height.
Aufgabe der vorliegenden Erfindung ist es, eine Tastatur mit einer geringen Einbauhöhe anzugeben, welche gleichzeitig sehr robust aufgebaut ist.The object of the present invention is to provide a keyboard with a low installation height, which is at the same time very robust.
Diese Aufgabe wird für die eingangs genannte Tastatur erfindungsgemäß dadurch gelöst, dass zwischen der Oberschale und der die Schaltkontakte tragenden Leiterplatte eine Trägerfolie vorgesehen ist, welche auf der der Leiterplatte zugewandten Seite Aktuatoren und auf der anderen Seite Aufnahmen für die Tasten aufweist, wobei die Aufnahmen im eingebauten Zustand durch die Durchbrüche in der Oberschale hindurchragen und mit ihren Rändern an der Unterseite der Oberschale anliegen, und dass die einzelnen Tasten auf den Aufnahmen befestigt sind.This object is achieved according to the invention for the keyboard mentioned at the outset by providing a carrier film between the upper shell and the circuit board carrying the switching contacts, which has actuators on the side facing the circuit board and receptacles for the keys on the other side, the receptacles in the project through the openings in the upper shell and rest with their edges on the underside of the upper shell, and that the individual buttons are attached to the receptacles.
Die erfindungsgemäße Tastatur zeichnet sich durch eine geringe Einbauhöhe aus und ermöglicht eine einfache Montage und ein einfaches Handling bei der Fertigung.
Durch die Verwendung einer PC-Trägerfolie ergibt sich eine im Gebrauch robuste Tastatur, welche aufgrund ihrer geringen Einbauhöhe bei der Gestaltung der eigentlichen Tasten, d. h. beim Design der Tasten, hohe Freiheitsgrade zulässt.The keyboard according to the invention is characterized by a low installation height and enables simple assembly and simple handling during manufacture. The use of a PC carrier film results in a keyboard which is robust in use and which, owing to its low installation height, permits a high degree of freedom in the design of the actual keys, ie in the design of the keys.
Weitere Ausgestaltungen der erfindungsgemäßen Tastatur ergeben sich aus den Unteransprüchen sowie aus einer nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der beigefügten Zeichnung.Further refinements of the keyboard according to the invention result from the subclaims and from a subsequent description of an exemplary embodiment with reference to the accompanying drawing.
In der Zeichnung zeigenShow in the drawing
Figur 1 einen teilweisen Querschnitt durch eine gemäß der vorliegenden Erfindung aufgebaute Tastatur, und1 shows a partial cross section through a keyboard constructed according to the present invention, and
Figur 2 eine schematische Explosionsdarstellung der die Tastatur bildenden Hauptbestandteile.Figure 2 is a schematic exploded view of the main components forming the keyboard.
Bei der Darstellung des Ausführungsbeispiels sind von dem Gehäuse mit der erfindungsgemäßen Tastatur lediglich Teile der Oberschale 1 mit den Durchbrüchen für die einzelnen Tasten dargestellt. Innerhalb des Gehäuses ist zwischen der Unterseite der Oberschale 1 und einer Leiterplatte 2 eine transparente Polycarbonat-Trägerfolie 3 angeordnet. Die transparente Folie dient zusätzlich als Lichtleiter.In the representation of the exemplary embodiment, only parts of the upper shell 1 with the openings for the individual keys are shown of the housing with the keyboard according to the invention. A transparent polycarbonate carrier film 3 is arranged within the housing between the underside of the upper shell 1 and a printed circuit board 2. The transparent film also serves as a light guide.
Diese Trägerfolie 3 weist auf ihrer der Leiterplatte 2 zugewandten Seite Aktuatoren 4 auf. Diese dienen zur Betätigung sogenannter "Knackfrösche" 8, die zur Herstellung des entsprechenden Kontaktes auf der Leiterplatte 2 dienen und gleichzeitig für ein gutes taktiles Verhalten (Klick) sorgen. Auf der anderen Seite der PC-Trägerfolie 3 sind Aufnahmen 5 für die Tastenkörper, z. B. 6, 7, vorgesehen. Hier ist festzustellen, dass die Aktuatoren 4 und die Aufnahmen 5 eine Einheit mit der PC-Trägerfolie 3 bilden und ebenfalls transparent ausgebildet sind.
Die Aufnahmen 5 für die Tastenkörper sind äquivalent zu der Oberschale 1 so ausgebildet, dass sie zum einen durch die Durchbrüche für die einzelnen Tastenkörper in der Oberschale 1 hindurchragen und gleichzeitig an der Unterseite der Oberschale 1 anliegen.This carrier film 3 has actuators 4 on its side facing the printed circuit board 2. These are used to actuate so-called "crack frogs" 8, which are used to produce the appropriate contact on the printed circuit board 2 and at the same time ensure good tactile behavior (click). On the other side of the PC carrier film 3 are recordings 5 for the key body, for. B. 6, 7 provided. It should be noted here that the actuators 4 and the receptacles 5 form a unit with the PC carrier film 3 and are also transparent. The receptacles 5 for the key bodies are equivalent to the upper shell 1 so that they protrude through the openings for the individual key bodies in the upper shell 1 and at the same time rest on the underside of the upper shell 1.
Die Positionsgenauigkeit zwischen PC-Trägerfolie 3, den Tastenkörpern, z. B. 6, 7, und der Leiterplatte 2 wird mit Hilfe von Positionierungsstiften 11, welche auf der Unterseite der Oberschale 1 angebracht sind, und durch die PC-Trägerfolie 3 und die Leiterplatte 2 hindurchragen, gewährleistet.The position accuracy between PC carrier film 3, the key bodies, for. B. 6, 7, and the circuit board 2 is ensured by means of positioning pins 11, which are attached to the underside of the upper shell 1, and protrude through the PC carrier film 3 and the circuit board 2.
Die Tastenkörper 6, 7, welche ebenfalls transparent ausgeführt sein können, werden auf den Aufnahmen 5 der PC- Trägerfolie 3 befestigt, indem sie auf die Aufnahme aufgeklebt, aufgeschweißt, gerastet, geklemmt oder mit der Aufnahme heiß verstemmt werden.The key bodies 6, 7, which can also be made transparent, are fastened to the receptacles 5 of the PC carrier film 3 by being glued, welded, latched, clamped or hot caulked to the receptacle.
Zum Heißverstemmen können die Tastenkörper an ihrer Unterseite Positionierungsstifte 10 aufweisen, welche in entsprechenden Durchbrüchen der Aufnahmen 5 heiß verstemmt werden. Darüber hinaus können aber auch bei einer Befestigung mittels Kleben oder Verschweißen zusätzlich Positionierungsstifte 10 zur besseren Ausrichtung des Tastenkörpers vorgesehen werden.For hot caulking, the key bodies can have positioning pins 10 on their underside, which are hot caulked in corresponding openings in the receptacles 5. In addition, positioning pins 10 can also be provided for better alignment of the key body even when fastened by means of gluing or welding.
Erfindungsgemäß ist zwischen der Oberseite der Oberschale 1 und den Randbereichen der Tastenkörper, z. B. 6, 7 eine gewellte Membran 9, welche z. B. aus Silikon besteht, vorgesehen. Diese Membran dient einmal als Staubschutz und darüber zum Toleranzausgleich, während ihre gewellte Form für die notwendige Rückstellungskraft nach dem Loslassen der Tastenkörper durch den Benutzer sorgt.
According to the invention between the top of the upper shell 1 and the edge regions of the key body, for. B. 6, 7 a corrugated membrane 9, which, for. B. consists of silicone, provided. This membrane serves as dust protection and above all for tolerance compensation, while its corrugated shape provides the necessary restoring force after the user releases the button body.
