Definitions

  • the invention relates to a key cap for a keyboard arranged in a device of the electrical communication technology, in particular the operating device of a telephone device, which is inserted into a housing opening of the device and can be pressed via a pin against a keyboard arranged inside the housing to actuate it.
  • dialing devices which have so far mostly been provided with a rotating dial.
  • dialing devices there are also devices of this type, and in particular car telephone devices, which have operating devices with dialing keyboards, by means of which the dialing process is made considerably easier.
  • the keyboards are provided with numbers or symbols according to their function, most of which are printed.
  • the operating device of a telephone device can either be a separate device with an associated handset, as is generally the case, or a handset in which the dialing and display units are integrated. In both cases keyboards are required, which are actuated by means of key caps inserted into the housing openings.
  • the invention has for its object to provide a stable and reliable guide for such key caps in the housing and to ensure good recognition or readability in different lighting conditions for numbers and symbols.
  • the key cap which can be inserted into the housing opening with lateral play and has a correspondingly configured pin on at least one side running parallel to the housing opening has a prestressed spring element which is inclined at an acute angle to the housing and which is on is supported on a stop surface in the housing and rests on the inside wall of the housing with the upper side of the laterally projecting contact surfaces formed by the spring elements and enlarged in diameter compared to the housing opening.
  • the key cap 1 consists of a downwardly open, half-shell-shaped plastic part of rectangular shape, on the longitudinal and transverse sides of which spring elements 2 are attached, preferably molded on. These spring elements 2 are fastened to the corners of the key cap 1 and run at an acute angle against the horizontal plane downwards, that is to say towards the housing 6 in which they are inserted.
  • the key cap 1 is stepped at the top, the middle, raised part 3 being provided with a recess corresponding to the number or symbol with which the key cap 1 is to be identified.
  • the number or the symbol exist made of a translucent plastic.
  • a light-collecting, fluorescent-colored plastic is used, which combines the advantageous properties that it is easily legible both during the day and sufficiently illuminated from inside and thus legible at night.
  • Fig. 5 shows the key cap 1 described above in the installed state.
  • Several keycaps are expediently arranged in a grid and provided with the symbols corresponding to their function.
  • the associated buttons 8 are mounted in the same grid, for example on a printed circuit board 10 and soldered in the example shown via solder connections 9.
  • the key cap 1 is inserted into the opening of a housing 6.
  • a lateral play is provided to prevent the key cap 1 from jamming.
  • the spring elements 2 are supported on a stop surface which is formed by a light guide 7 which has a correspondingly designed bore for receiving the pin 5 of the key cap 1.
  • the light guide 7 serves to supply the light to the numbers or symbols in the key cap 1.
  • the key cap 1 is pressed with its pin 5 onto the key 8 and is reset by the four spring elements 2 attached laterally to the key cap 1 in the exemplary embodiment.
  • the four spring elements 2 attached laterally to the key cap 1 in the exemplary embodiment.
  • the integrated spring elements simplify assembly considerably. The elimination of a separate spring not only simplifies assembly, but also reduces costs.
