TastenknopfKey button

Die Neuerung betrifft einen Tastenknopf für Kommunikations-Endgeräte und dessen Führung in der Aufnahmekammer der Gerätekappe.The innovation concerns a button for communication devices and its guide in the receiving chamber of the device cap.

Die Entwicklung von Tastaturen von Kommunikations-Endgeräten führte von Kontaktfedertasten über Leiterplatten mit aufgesetzten Kontaktmatten zur Verwendung von Schaltfolien anstelle doppelseitig kaschierter Leiterplatten. Dabei besteht eine Tastatur prinzipiell aus den erforderlichen Tastenknöpfen einer Schaltmatte, einer Kontaktfolie und einer Druckplatte. In dieser Reihenfolge wird auch die Montage der Tastatur in der Endgerätekappe vorgenommen, wobei die Montage durch Automaten gesteuert und nur in Ausnahmefällen manuell vorgenommen wird. Durch das Montieren der Bodenwanne des Endgerätes wird die Druckplatte in ihrer Endlage fixiert und somit die Tastatur in ihre Betriebsstellung gebracht.The development of keyboards for communication devices has led from contact spring keys to circuit boards with attached contact mats to the use of switching foils instead of double-sided laminated circuit boards. A keyboard basically consists of the required buttons on a switching mat, a contact foil and a pressure plate. The keyboard is also mounted in the terminal cap in this order, with the assembly being controlled by machines and only carried out manually in exceptional cases. By mounting the base tray of the terminal, the pressure plate is fixed in its end position and the keyboard is thus brought into its operating position.

Der Neuerung lag die Aufgabe zugrunde, die für eine Tastatur von Kommunikations-Endgeräten erforderlichen Tastenknöpfe und deren Halterungen bzw. Führungen in der Gerätekappe derart zu gestalten, daß deren automatische Montage ermöglicht und bei einer manuellen Montage ein falsches Einsetzen der Tastenknöpfe ausgeschlossen ist.The innovation was based on the task of designing the key buttons required for a keyboard of communication terminals and their holders or guides in the device cap in such a way that they can be installed automatically and that incorrect insertion of the key buttons is excluded during manual installation.

Diese Aufgabe ist durch die Neuerung gelöst, wie sie im Kennzeichnungsteil des Schutzanspruches dargelegt ist.This problem is solved by the innovation as set out in the characterising part of the protection claim.

Anhand einer Zeichnung wird die Neuerung nachfolgend näher erläutert. Die Zeichnung stellt eine Teilansicht auf die Rückseite einer Kappe eines Kommunikations-Endgerätes dar, als vergrößterter Ausschnitt als Führung eines Tastenknopfes.The innovation is explained in more detail below using a drawing. The drawing shows a partial view of the back of a communication device cap, as an enlarged section showing the guide of a key button.

Eine Vielzahl rechtwinklig zueinander liegender Wände 11 bilden Aufnahmekammern 10 für die Tastenknöpfe 20. Die Tastenknöpfe 20, im gezeigten Beispiel rund geformt, die aber ebenso oval oder rechteckig ausgeführt sein können, weisen zwei diametral gegenüberliegende Führungsnuten 21 auf. Die Wände 11 sind mit entsprechenden Führungsstegen 12 versehen, an denen die Tastenknöpfe 20 gleiten. Durch diese Maßnahme sind die Tastenknöpfe 20 gegen ein Verdrehen gesichert. Diese Maßnahme ist außerdem erforderlich bei einer möglichen manuellen Montage. Außerdem dienen die Führungsnuten 21 auch dem Leiten der Tastenknöpfe in der Tastentrennvorrichtung des Bestückungsautomaten beim Zusammenbau des Kommunikations-Endgerätes. Jeder Fallkanal des Bestückungsautomaten hat durchgehende Führungsstege, die auf die Führungsstege 12 der Kappe aufsetzen und bis zum Einfallen der Knöpfe 20 in die Aufnahmekammern 11 wirksam sind.A large number of walls 11 lying at right angles to one another form receiving chambers 10 for the key buttons 20. The key buttons 20, which are round in the example shown but can also be oval or rectangular, have two diametrically opposed guide grooves 21. The walls 11 are provided with corresponding guide webs 12 on which the key buttons 20 slide. This measure secures the key buttons 20 against twisting. This measure is also necessary if manual assembly is possible. The guide grooves 21 also serve to guide the key buttons in the key separator of the placement machine when assembling the communication terminal. Each drop channel of the placement machine has continuous guide webs that rest on the guide webs 12 of the cap and are effective until the buttons 20 fall into the receiving chambers 11.

Die Tastenknöpfe 20 tragen am Umfang weiterhin drei um jeweils 120 Grad versetzte Anschlagstege 22. Diese Anschlagstege 22 dienen dem Höhenanschlag der Tastenknöpfe 20 an den Kappendurchbrüchen 13. Ein gegenüber den zwei Führungsstegen 12 je Aufnahmekammer 10 um 90 Grad versetzter kürzerer Steg 14 verhindert ein falsches Einsetzen der Tastenknöpfe 20. Bei einem Verdrehen des Tastenknopfes um 180 Grad setzt ein Anschlagsteg 22 auf den kürzeren Steg 14 auf, so daß der Tastenknopf 20 in seiner Endlage die Wände 11 überragt. Dies wird als Bestückungsfehler erkannt.The key buttons 20 also have three stop bars 22 on the circumference, each offset by 120 degrees. These stop bars 22 serve to stop the height of the key buttons 20 at the cap openings 13. A shorter bar 14 offset by 90 degrees from the two guide bars 12 per receiving chamber 10 prevents the key buttons 20 from being inserted incorrectly. If the key button is rotated by 180 degrees, a stop bar 22 rests on the shorter bar 14 so that the key button 20 protrudes beyond the walls 11 in its final position. This is recognized as an assembly error.

Kreissegmentförmige, seitliche im Winkel von 90 Grad zu den Führungsnuten 21 angeordnete Hubstege 23 dienen der Hubbegrenzung der einzelnen Tasten. Die Hubbälge der Schaltmatte liegen an der Fläche zwischen den Hubstegen an.Circular segment-shaped lifting bars 23 arranged at the sides at an angle of 90 degrees to the guide grooves 21 serve to limit the stroke of the individual keys. The lifting bellows of the switch mat rest on the surface between the lifting bars.
