Definitions

  • a keyboard with keys of this type is known, the above deformable means of which consist of a flexible membrane common to all the keys and placed above the support plate to protect the cells and ensure the elastic return of the keys to which said membrane is connected by pinching with an element of the switch.
  • the object of the invention is more particularly to remedy these drawbacks and to provide the user with a fully waterproof keyboard with tactile effect controlled for the duration of the maneuver.
  • the aforesaid membrane, the aforesaid spike and, possibly, the aforementioned touch may form a single piece made of an elastically deformable material such as, for example, an elastomer.
  • the pin may have a cylindrical and / or frustoconical shape whose large base, which merges with the membrane, comes to bear on an elastically deformable member of the switch.
  • the desired tactile effect can be obtained by an appropriate choice of the elastic modulus of the elastomer, the shape and height of the pin, as well as the dimensions and the conformation of the key.
  • the limiting means may in particular consist of a cavity formed in the underside of the key and in which the pin engages, this cavity being shaped so as to allow the free expansion of the pin in the pre-stroke phase and to contain at less partially the expansion at the end of the overtravel phase.
  • the elastically deformable member of the switch may consist of a blade or a cup with a snap effect which deforms elastically only from a predetermined force threshold.
  • the invention also relates to a keyboard produced using the previously defined key.
  • the aforesaid support may be in the form of a plate, for example a printed circuit plate, provided with a plurality of cells capable of each receiving a switch element.
  • This plate is then covered by the aforesaid membrane which comprises, at each of the cells, an elastically deformable pin actuable by a key.
  • the keyboard portion 1 shown in FIG. 1 comprises a support plate 2 constituted by a printed circuit allowing in particular the electrical connection of said keyboard 1 to an apparatus (not shown).
  • the support plate 2 is provided with a plurality of cells 3 arranged in rows and / or columns. Each of these cells 3 constitutes the housing a switch 4 formed of conductive elements or pads 5, 6, 7 arranged at the bottom of the cell 3 and capable of cooperating by electrical contact with a conductive blade 18 elastically deformable and acting by snap-action, this in order to establish the connection of pad 6 with pads 5 and 7.
  • the cells 3 are recessed in the upper plane of the support plate 2 or printed circuit on which is arranged a membrane 8 constituting deformable means which, associated with a set 9 push-button-switch, provide the user with a tactile sensation.
  • the membrane 8 is full, that is to say having no opening to allow the passage of one of the elements of the assembly 9. It is made of an elastomeric material and is bristled as much pins 10 that there are switches 4 to control.
  • the pins 10 are axially deformable in compression. They came integrally with said membrane 8 and are capable of interposing, during the mounting of the latter, between a button 11 and the switch 4 to constitute a pusher.
  • each of the pins is fixed to the support plate 2 so that each of the pins is in the axis of a corresponding cell 3.
  • this fixing is ensured by means of an openwork structure 12 having the shape of a grid, comprising a plurality of cavities 16 separated by partitions 14, 15, this structure 12 being disposed on the membrane 8 and fixed on the support plate 2 thanks to fixing means such as hot crimping elements 13 or even screws (not shown).
  • each of the cavities 16 is intended to receive a corresponding pin 10 and to ensure the axial guidance of the button 11 associated with this pin 10.
  • the pin 10 or pusher thus consists of a mass of elastomer with a variable frustoconical section, the large base of which merges with the membrane 8.
  • the modulus of elasticity of this elastomer is chosen to be relatively low.
  • these means for limiting the expansion of the pin 10 are constituted by a lower cavity 19 of the key 11 in which the pin 10 is housed and centered.
  • the dimensions and the shape of the cavity 19 are such that they allow its free expansion in the precourse phase OF corresponding to the crushing ⁇ (measured relative to the reference plane PP ′ of the top of the pin 10 in the rest position) and to contain said expansion during the overtravel F ′, F ⁇ corresponding to the crushing ⁇ ′ for a predetermined volume of the pin 10 corresponding to that of the cavity 19 whose edges 19 a are in this case chamfered.
  • the button 11 is completely pressed into the cavity 16 of the structure 12.
