Definitions

  • the invention relates to a control device electric, push button type, especially for printed circuits.
  • Control devices of this type which are known, have the disadvantage of being bulky because they use as push buttons elements in form of two-arm levers, which are pivotally mounted around an axis supported by a fixed structure, between a rest position and a control position, at against a return spring. So the advantage of small footprint provided by printed circuits, is lost due to the bulky control device.
  • the object of the present invention is to provide a control device, of the type indicated above, which does not does not have the disadvantage of the state of the art and allows the production of printed circuit assemblies and small control device.
  • an organ of control consists of a cup in the form of a curved membrane, comprising rim portions and a central part in mutual electrical contact and placed on one side of a printed circuit board, on the one hand, so that at least a portion of the rim portion in electrical contact with the central part is in support on a metallized area of the printed circuit and the part central or opposite another metallized zone of the printed circuit and, on the other hand, so as to be deformable between a state of rest to which the party central is far from said metallized zone opposite of the printed circuit, and a position pressed in which the central area is in contact with said metallized part, and in that a sheet of material flexible is glued to the face of the circuit board printed carrying said cup to fix it in its rest position.
  • the device control comprises a plurality of control elements in the shape of a cup, and these elements are arranged on an area of the printed circuit board, which does not include no electrical components, the material sheet flexible positioning of the cups being bonded to this component-free area.
  • a diode is associated with each element of cup-shaped control and plate and sheet aforementioned positioning respectively have a hole and a transparent area to indicate the operator of the control device the state of the element control.
  • reference numbers 1, 2 and 3 respectively illustrate a support frame, a plate printed circuit and a sheet of flexible material intended to be glued to the upper face 4, which is visible, from plate 2.
  • the latter is configured to be received in support frame 1, like the shows figures 2 and 3 by resting on pins support 6 integral with bottom elements 7 of the frame.
  • the figure also shows that the upper side 4 of the printed circuit board on which the cover sheet 3 only has areas and metallized printed circuit tracks 9 while the electrical components of the printed circuit are mounted on the underside 10 of the plate 2.
  • the components are schematically indicated in 12.
  • the reference number 13 designates the connection wires electric outdoor, connected to connection points appropriate from the underside 10 of the plate 2.
  • the control device comprises four control elements 15, each consisting a cup 15 formed by a curved membrane and made of an electrically conductive material, advantageously metallic.
  • the cups 15 have a square shape, with cut corners and arc-shaped edges circle, to form a leg at each corner support 16 by which the cups bear on metallized areas 17 of the printed circuit, which make part of the track system 9.
  • the legs 16 are straightened, as clearly shown in Figure 4.
  • the printed circuit includes a portion metallized and thus conductive 20 connected by a track conductive 21 to a metallized hole 22 which crosses the plate 2 to be electrically connected to a component 12 located on the other side of the plate 2.
  • the cup 15 is deformable between two states, namely the rest state or normal to which the cup has the shape illustrated on Figure 4 and to which the central part 18 is distant of the conductive area 20 of the printed circuit, and the state pressed by pressing on the central part 19, to which this last comes in electrical contact with the area conductive 20. When the operator releases the pressure on the central part of the cup, this amounts to his state of rest.
  • Each control cup 15 is associated with a diode light emitting 24 arranged in a through hole 25 practiced in plate 2. This diode is visible from outside through a transparent circular area 27 of the covering and positioning sheet 3 of cups 15. The diode 24 serves as a means of displaying the condition of the cup. When the cup is in its state diode 24 is not energized. However, at the following the insertion of the cup, the diode is excited and the light it emits crosses the area transparent 27 of the covering sheet 3.
  • cover sheet 3 it is still note that it adheres to the upper side 4 of the plate printed circuit by being retained by a layer of glue which has been previously applied to this face 4. Consequently, the cups 15 are positioned and retained on plate 2 without being glued to the sheet 3. It can also be seen that on the external face 29 of this sheet, the support area for actuating a cup is indicated by a rectangle 30. The display area 27 of the diode 24 associated with the cup 15 surrounded by the corresponding rectangle 3 is located inside the rectangle, as clearly seen in Figure 1.
  • the bottom elements 7 could be configured so as to have a sufficient surface near the edge of the frame to allow drilling of through holes for fixing screws on a support structure.
  • the support pins 6 could be removed.
  • plate 2 could be fixed in the frame advantageously removably for example by lugs provided on the internal face of the frame and the recesses in the lateral face of the plate or vice versa. It is also possible to confer on at least some of the internal side faces of the frame an inclined shape widening towards the bottom and the face side of the plate a complementary shape for get the plate retainer in the frame by interlocking. In general, we could plan in top of side face of frame retainers of the plate, projecting towards the center of the frame.
  • the device according to the invention allows the exit of the wires external electrical connection through the bottom of the frame since this one is open. We could however also consider passing the wires from connection through a window in the wall side of the frame, if this would be beneficial for installation of the device.
