Definitions

  • the present invention relates to a keyboard for a communication terminal consisting of a lower and upper shell, openings being provided in the upper shell for the keys of the keyboard and the individual keys having webs on their undersides for actuating corresponding contacts on a printed circuit board.
  • the object of the present invention is to provide a keyboard that is as flat and seamless as possible, in which the gap dimensions between the individual keys are small and even, in order to allow greater design freedom than in the previous keyboards.
  • an elastic film is arranged between the top of the upper shell and the undersides of the keys, which beads have beads which essentially limit the areas corresponding to the individual keys and serve as a reset device.
  • the keyboard according to the invention is distinguished by an extremely flat structure, the individual keys being protected against contamination, e.g. B. are protected by dust. At the same time, the required ESD resistance is guaranteed.
  • FIG. 1 shows a cross-sectional view through a partially sectioned perspective of a first embodiment of the keyboard according to the invention
  • Figure 2 is a plan view of the elastic film of the keyboard shown in Figure 1, and
  • FIG. 3 shows a cross-sectional view through a partially sectioned perspective of a second embodiment of the keyboard according to the invention
  • the illustrated keyboard of the first embodiment essentially consists of the individual keys, e.g. 1, 2, 3, and the elastic film 4.
  • the elastic film can e.g. be a silicone mat.
  • buttons 1, 2, 3 lie flat with their undersides on parts of the top of the silicone mat 4, as can be clearly seen from FIG.
  • the individual areas of the silicone mat 4 corresponding to the buttons are each delimited by beads 11, which are formed in the shape of an rim and are directed downwards. These beads rest on parts of the upper housing shell 5.
  • the parts of the upper housing shell 5 below the keyboard and the silicone mat 4 have openings 12, 13 lying one above the other, through which a vertical web 6, which is firmly connected to the single button protrudes. These webs serve to actuate corresponding contacts arranged on a printed circuit board in the mobile radio device.
  • resilient hooks 8, 9, 10 are fastened, which likewise protrude through openings in the upper housing shell 5 and the silicone mat 4 and come into engagement with the upper housing shell 5 in order to prevent the individual keys from jumping off.
  • FIG. 3 shows a second embodiment of the keyboard according to the invention.
  • FIG. 3 also shows only part of a keyboard for a mobile radio device.
  • the keyboard shown the second embodiment consists essentially of the individual keys, for. B. 21, 22, 23, and the elastic film 24.
  • This elastic film 24 can, for. B. be a silicone mat.
  • buttons e.g. B. 21, 22, 23, lie with their lower edge regions on the bead 31 delimiting their key region.
  • the elastic film 24 serves to seal the interior of the housing against dust and to provide the restoring forces for the individual keys.
  • the parts of the upper housing shell 25 and the silicone mat 24 below the keyboard have openings 32, 33 one above the other, through which a vertical web 26, which is firmly connected to the individual key, projects.
  • resilient hooks 28, 29, 30 are fastened to the respective keys, which likewise protrude through openings in the upper housing shell 25 and the silicone mat 24 and come into engagement with the upper housing shell 25 in order to prevent the individual keys from jumping off.

Abstract

L'invention concerne un clavier destiné à un terminal de communication, composé d'une coque supérieure et inférieure (5). Une feuille élastique (4) est placée entre la face supérieure de la coque supérieure et la face inférieure des touches (1, 2, 3) du clavier. Cette feuille présente des bourrelets (11), qui délimitent sensiblement les surfaces correspondant à chaque touche (1, 2, 3) et servent de dispositif de rappel.
