Definitions

  • the invention relates to a control keyboard, in particular for a motor vehicle air conditioning system according to the preamble of the claim.
  • a long-stroke push button is known from EP 0 157 037 A2, which within its Housing is forced.
  • US 5 588 760 discloses a key switch for a computer keyboard. Here is one Forced guidance of the keys using round key holders.
  • a pressure switch as a push button for US 5120 923 describes a data input from a PC.
  • DE 196 27 212 A1 describes an actuation unit for a vehicle component, in particular for a vehicle air conditioning system, described, which can be installed in a front panel and has switch actuators arranged movably in the front.
  • a push button switch with a small overall height is described in US Pat. No. 4,918,271. contacts a base plate are closed by a rubber-elastic switching knob on which a Stylus rests, which can be moved vertically in a guide in the housing of the tact switch is.
  • a button with a liquid crystal display for electric typewriters or computer devices GB 2 150 722 A can be found.
  • a switch is made using the side edges of the Button pressed.
  • PCB, conductive rubber parts as the display element are also on a common base in a U-shaped recess held on resilient tongues.
  • FIG. 1 Another actuation unit for an electrical device, which can be installed in a front panel DE 196 27 231 C1 discloses. Assigned switch actuators Butt elements are relative when exerted on the printed circuit board pressing force movable to the film, switch contact surfaces of the circuit board through contact surfaces on Tappet element are bridged. The circuit board is covered by parts of the front panel held and pressed against the front panel.
  • DE 44 10 512 A1 discloses parts of a carrier plate and device wall via a spring element to seal with each other, so that both sealing surfaces under spring pressure lie on top of each other in order to ensure a contact pressure of the sealing surfaces.
  • the carrier plate has spring elements on two opposite sides, which are made up of a fixed leg and a movable leg. The movable leg reaches through with its free end through the carrier plate, while the fixed leg is attached with its end to the support plate.
  • the invention has for its object to design a control keyboard such that a small Construction depth and simple assembly of the individual parts without the use of connecting elements is achievable.
  • Fig. 1 shows a plan view
  • Fig. 2 shows a side view of a control keyboard 1, in particular for a motor vehicle air conditioning system that can be installed in the front of a dashboard 2, consisting of a housing 3, in which electrical and electronic components are arranged are, with several keys 4 of the keyboard acting on switch 5 (Fig. 9) on a Printed circuit board 6 (Fig. 9) are arranged.
  • the guide stamp 10 and the key guide attachment 7 have a dovetail guide 14 form (Fig. 13) which through recesses 15, 16 of the circuit board 6 and a support plate 17 protrudes (Fig. 9).
  • a dovetail guide 14 form (Fig. 13) which through recesses 15, 16 of the circuit board 6 and a support plate 17 protrudes (Fig. 9).
  • the locking 11 is by a locking projection 20 on the guide stamp 10 and a Recess 21 formed in the guide lug 7, as can be seen from Fig. 9, the Locking lug 20 with elastic deformation of the guide lug wall into the recess 21 snaps into place. This eliminates connecting and securing elements.
  • the control keyboard 1 has a known one LCD display on (Fig. 10), the support plate 17 with bent gripping lugs 32 holds an LCD element 33, which is clamped over conductors 34 with conductors of the Printed circuit board 3 is contacted. Due to the tensioned conductive rubber pieces 34 is permanently elastic Holder of the LCD element 33 has been reached.
  • the support plate 17 has a spring extension encompassing the housing frame 30 35 has (Fig. 7 and 8) in the dashboard 2 with the control keyboard inserted 1 is compressed by the dashboard wall and this dashboard wall clasped with a complementary hook formation 36, the opposite other side of the housing frame 30 (Fig. 2) with a connector receptacle 37 and the Housing front wall 26 forms a receiving groove 38 for the dashboard wall.
  • the control keyboard 1 needs only with the receiving groove 38 in the opening of the dashboard 2 or inserted over the dashboard wall and with the other side in the Opening to be pressed in so that the spring extension 35 compresses and the dashboard wall clasped with the hook formation 36. This makes it easy to attach reached on the control keyboard.
  • FIGS. 9 to 11 which show cross sections of the control keyboard 1, it is provided that that the bent gripping lugs 32 are bent on both sides of the carrier plate 17 Angular lugs 40 exist, with recesses 41 in the bending area 42 (FIGS. 7 and 8) are arranged that leg extensions 43, 44 above and below the bending area 42nd exist, so that the leg extensions 43, 44, the angle extensions 40 with respect to the housing frame walls 45 can align in parallel.
  • the carrier plate 17 can be made in the recesses 16 which protrude through the guide punches 10, have bent locking surfaces 46, on which the circuit board 17 can be supported precisely.
  • FIG. 12 shows an enlarged detail from FIG. 11, from which it can be seen how the Clip approach 27 of the support plate 17 has snapped into the clip slot 31, and just like that Leg approaches 43 and 44, the angle approaches 40 with respect to the housing frame walls Align 45 parallel.
