Definitions

  • the invention relates to a key with a bell-shaped or dome-shaped key body made of elastic material, which can be clamped with an edge delimiting its open side between a base plate and a key housing part.
  • Such a button is known from DE-A-30 41 470.
  • the key body designated there as the sealing membrane sits with its flat outer edge on the surface of a base plate referred to there as a support part and is pressed against the base plate by a housing part called a cap there.
  • a housing part called a cap there As a result, the space enclosed by the key body and the base plate, in which the contacts of the key are located, is sealed off from the outside world, in particular from the operating side of the key, so that, at least from this side, no foreign bodies in the contact space formed by the key body and base plate can reach.
  • the key known from DE-A-30 41 470 can also be used as a key module, so that a keyboard can be formed from several such keys, which are attached to a plate.
  • buttons efforts are made to arrange the fixed contacts directly on a plate to which the button is attached. In such a case, the number of parts that make up the key can be further reduced. The outer edge of the key body can then be clamped between a housing part of the key and this plate.
  • the object of the present invention is therefore to design a key of the type mentioned in the introduction in such a way that only a single key part has to be handled when such keys are attached to a plate carrying the fixed contacts of the keys.
  • this object is achieved in that the key housing part in the region of the key body edge on its side facing the key body has niche-like recesses with access openings provided essentially at right angles to the base plate and in that the key body has projections in the region of its edge.
  • the key body and the key housing part can be connected to each other before fixing these parts to a plate carrying the fixed contacts of the key, without special connecting means such.
  • B. adhesive are required. This gives a composite body consisting of the key housing part and the key body, which can be handled in an uncomplicated manner and therefore considerably simplifies the assembly process.
  • the niche-like recesses consist of a coherent circumferential groove of the key housing part and that the key body has a web-like approach corresponding to the groove on its edge.
  • the key housing part is provided on its side parallel to the open side of the key body with snap pins.
  • the composite body consisting of the key housing part and the key body can be particularly easily attached to the plate carrying the fixed contacts of the key.
  • the key body has at its edge a wedge-shaped circumferential web projecting from this edge parallel to the direction of the axis of the key, that the key housing part is provided on the outside in the region of the edge with a circumferential edge attachment, ' which has a wedge-shaped, circumferential web projecting parallel to the axis, and that the key housing part on its side facing away from the open side of the key body has a hollow cylindrical extension, that the extension on its inside is provided with grooves parallel to the axis, and that ramp bodies are arranged in the grooves, each of which has a steeper sliding surface on its side facing the key body than on the side facing away from the key body.
  • the figure shows, enlarged and in section, a side view of the composite body consisting of the key housing part and the key body, which is locked on a plate carrying the fixed contacts of the key.
  • the key housing part 1 which is made of a dimensionally stable plastic and with side walls 3 extending at right angles to a base plate 2, encloses a space 4 in which the key body 5, which is made of an elastic plastic material or rubber, is arranged.
  • the approximately dome-shaped or bell-shaped key body 5 has a thickened edge 6 facing the plate 2, which has a parallel to the plate 2 and to Key housing part 1 facing web-like approach 7 is provided.
  • This approach 7 is fitted into a circumferential groove 8 of the key housing part 1, which is delimited by two webs 9, 10.
  • the webs 9, 10 are directed towards the center of the key body 5 and thereby comprise the projection 7 together with the side walls 3 of the key housing part 1 such that the key body 5 fitted into the groove 8 with the web-like extension 7 in this way with the key housing part 1 is connected.
  • the web 10 of the key housing part 1 which is more distant from the base plate 2 also serves as an abutment to counter the edge 6 of the key body protruding toward the base plate 2 when the composite body 11 consisting of the key housing part 1 and the key body 5 is placed on the base plate 2 to press the base plate 2.
  • radially resilient dowel pins 12 penetrate holes 13 provided in the base plate 2 and adapted to the dowel pins 12. In the radially resilient area of the dowel pins 12, these are provided with a collar 14 which increases their diameter. This collar 14 can pass through the radial compression of the dowel pins 12 through the bore 13 in the base plate 2 and then, by returning to its original circumference, locks the composite body 11 on the base plate 2.
  • the radial compressibility of the dowel pins 12 can e.g. B. caused by a slit 15 of these pins.
  • a contact space 16 is sealed off from the outside world, in particular from the operating side of the key, since the edge of the bell-shaped or dome-shaped key body 5 is pressed against the base plate 2.
  • the sealing effect can be further improved by a wedge-shaped web 17 of the key body 5 projecting from this edge 6 against the base plate 2.
  • the sealing of the contact space 16 with respect to the outside of the key can be further improved if the key housing part 1 is provided in the region of the edge 6 of the key body 5 with an outer circumferential edge attachment 25 which has a circumferential, wedge-shaped web directed towards the base plate 2 28 has.
  • this web 28 presses into an elastic mat 29, indicated in dashed lines in the figure, placed on the plate 2, which for the area of the plate 2, which is delimited by one of the webs 9, Has recesses.
  • Such a mat 29 is, for. B. provided for shielding electrostatic interference from a keyboard.
  • a key cap provided with resilient snap arms, the snap arms of which slide in the grooves 24, can thereby be easily connected to the housing part 1.
  • the axis 21 can be resilient.
  • Retractable snap arms slide the ramp bodies 23 slightly from the sides 26, but are then locked by the sides 27 with projections provided at the ends of the snap arms and directed against the grooves 24.
  • the key cap is pressed in further, it touches the key body 5 with central projections and finally causes it to collapse or collapse. If the key cap is released, it is brought back into the starting position by the key body 5.
  • keyboards can be built in an uncomplicated manner, keyboards can be changed in their structure, and finally key modules can be exchanged.
