Definitions

  • the invention relates to a keypad according to the preamble of claim 1.
  • the keypad described there has a supporting frame as the lower housing part, on which a circuit board with the fixed contacts rests. There is a contact mat with domes, in which the movable contacts are attached. The circuit board and switch mat are held in place by a latched button guide that represents the upper part of the housing. In this upper part, the buttons are guided in corresponding openings, which each press when pressed on the corresponding dome and thereby close the respective contacts on the circuit board.
  • the invention has for its object to provide a keypad with a different, simple structure in connection with a display device (display) that can be harmoniously inserted into a communication terminal.
  • This object is achieved by the features specified in claim 1. Further training can be found in the subclaims.
  • the advantage of this construction is the arrangement of the keys on both sides of a display device, the latter being either between or below the keys.
  • additional labeling strips can be attached under the buttons. Since the actuating parts of the keys only protrude from the outer edge over the display or labeling field, on the one hand good legibility is ensured, and on the other hand the space required for the keys and display is as small as possible.
  • Another advantage is the simple mounting of the buttons on the carrier.
  • the keypad shown in FIGS. 1 and 2 has two rows of keys 1, which are arranged on both sides of a display device 2 (display) on a carrier 3.
  • the carrier 3 has in its central part the cross section of an upside-down U and with its free legs 5 stands on a printed circuit board 9 which roughly corresponds in outline to that of the keypad.
  • the display device 2 sits below its crosspiece 4, the connections of which are connected to contacts of the printed circuit board 9 by means of two conductive rubber strips 10, the conductive rubber strips 10 resting against the free legs 5 of the carrier 3 on the inside.
  • the carrier 3 is made of transparent plastic, so that the legibility of the display device 2 is not impaired.
  • the crossbar 4 of the U is extended on both sides beyond the attachment points of the two free legs 5. These extensions 7 form the guides for the buttons 1 and are described in more detail.
  • the keys 1 each have a w-shaped cross-section, the outer free leg 14 being substantially longer than the other two legs 15 and 16.
  • the protruding end is at right angles to the inside, this cross leg being so long that it has at least the other two legs covered.
  • the cross leg is the actuating part 8 of the button 1.
  • the middle leg 15 has a short extension 17 on both sides at the free end, which slides on the guide of the carrier 3.
  • the crossbar 23 of the w-shaped profile of the button 1 acts on the respective switching dome 13 of the switching mat strip 12.
  • the guide on the carrier 3 for the keys 1 is m-shaped in cross-section, the transverse web of this m-shaped profile being the extension 7 already mentioned and the free leg located on the inside in each case also being the one already mentioned with the reference number 5 with which the carrier 3 stands on the printed circuit board 9.
  • the two other legs 19 and 20 each have a short extension 21 and 22 on one side at the free end, these extensions being directed away from one another.
  • the two outer legs 14 and 16 of the button 1 slide on them. In total, four sliding surfaces are thus provided for each button, which prevent tilting when actuated and form a reliable guide.
  • the guide has the advantage that the keys 1 can be easily inserted from the front of the keypad during assembly.
  • buttons 1 are injection molded from transparent plastic, labeling strips 24 can be read, which are inserted under the actuating parts 8 and e.g. can be provided with symbols, names or numbers of other participants.
  • buttons 1 are moved together and a display device 2a is located directly below them, so that symbols, names, numbers etc. can be displayed continuously, pulsating or alternating directly under the keys 1, which at the same time enables simplified user guidance.
  • the carrier 3a is made correspondingly narrower than the one described above in the central part of its transverse web 4a, and the printed circuit board 9a can also be correspondingly smaller than that of the embodiment according to FIGS. 1 and 2. All other parts, in particular the buttons 1 and their guidance, are designed in the same way as in the previously described version.
