Definitions

  • the invention is based on an input device of the type of the independent claim.
  • the input device according to the invention with the features of the independent Claim has the advantage that a simple low-cost membrane keyboard can be used can, their electrical and mechanical connection at any time easy to separate.
  • the membrane keyboard can according to the invention be replaced without parts of the mechanical Connection must be destroyed or renewed.
  • the seal which advantageously ensures that penetration water or moisture in the input device prevents so shorts can be avoided to be used again.
  • the seal is from a Elastomer produced that resistant to ultraviolet Radiation and ozone is.
  • the input device with a Mounting frame is installed in a chamber, the chamber has at least one pin or a socket in the The plug is inserted to make an electrical connection manufacture.
  • connection lugs are used. At connection lugs If no plug is necessary, here is a direct connection, wherein the conductor tracks in the plug-in area of the Terminal lugs formed with Silberleit laminate and graphite are.
  • the plug either on the flexible film outlet crimped or glued becomes.
  • the plug can be used as a female connector or as Pin connector be formed. Both are common stekker executions, which are available by default and thus also to a simple embodiment of the invention Lead input device.
  • Membrane keyboards for entering a code or other information are often used in home and time management. This can be an access system or a time recording system will be realized. These membrane keypads can especially in outdoor areas, but also indoors be used with a humid climate. humidity must not penetrate into such membrane keyboards, because then it can cause corrosion and u. U. also come to short circuits.
  • a membrane keyboard is used where a foil is the electronics and sensors of the keyboard encloses and a seal the film outlet waterproof seals.
  • the seal via connecting means which are attached to the film exit, arranged.
  • These Seal is preferably made flexible.
  • the seal is here formed as an elastomer, wherein silicone rubber can be used. The material must be resistant to be ultraviolet radiation or ozone.
  • connecting means connecting lugs or plugs be used.
  • the plug is thereby on the film exit crimped or glued or clamped.
  • the foil usually consists of a polyester material.
  • a mounting frame is used to install the membrane keyboard, wherein the membrane keyboard thereby introduced into a chamber which has a receptacle for the plug. This recording is either with at least one pen or one Jack realized.
  • FIG. 1 shows in a first exploded view which components formed the input device according to the invention becomes.
  • a membrane keyboard 1 with the necessary electronics is in a slide that also has a slide exit 2 wrapped.
  • the film exit 2 can also be a conductor foil be.
  • LEDs are for display and / or lighting integrated. It is also possible Here is a display panel, such as a liquid crystal display provided.
  • the electrical cables that of the membrane keyboard 1 and its electronics lead away.
  • a plug 4 is crimped, over which now a flexible seal 3 is slipped.
  • the plug 4 is used to connect to another electronics, to forward signals from the membrane keyboard 1 or the membrane keyboard with control signals and energy too supply.
  • the membrane keyboard 1 with the film outlet 2, the seal 3rd and the plug 4 are guided in a mounting frame 5, which is used for installation on a wall and a certain protection Before observations of inputs provides by the mounting frame 5 has an elevated fold, which is a lateral observation prevented. It is here depending on the application the input device according to the invention also other mounting frame without such a fold possible.
  • a chamber 7 which has a socket 6 into which the plug 4, the seal 3 and the flexible film exit 2 introduced become.
  • the chamber 7 and the seal 3 together form the waterproof area.
  • the chamber has one more Input unit on which is shed and internally with a also potted cable is wired.
  • the plug 4 is, for example, connected to a bus to the forward electrical signals.
  • the use of a Busses is particularly when using multiple membrane keyboards of interest to save cables. However, it is also possible to use a two-wire line. Also the Connection to a radio module can be useful here to a Completely avoid wiring.
  • the mounting frame 5, the Chamber 7 and the membrane keyboard 1 are all made of plastic executed.
  • the mounting frame 5 may alternatively made of metal be made. This also applies to the chamber 7, in which case the chamber must have 7 plastic inserts to provide insulation to reach.
  • the membrane keyboard also receives its electrical Energy. If, for example, a bus is used for connection, then a power line transmission can be used d. H. over the bus can by a Gleichstromomanteil a Supply of connected bus stations are carried out, wherein a modulation of the DC component for the transmission of Data serves. Since the membrane keyboard 1 here only for input serves, it can only be performed as a transmitter. It is then in a figurative sense a taxable Power source. It can alternatively also separate cables for the power supply or a battery can be used.
  • the membrane keyboard 1 is integrated in an input device, which also has a Issue has, for example, a display. In this case, that must be Input device then have its own signal processing, or it must also data via the connector 4 receivable be. Are such output means as an indicator or a Speaker provided, then is also a corresponding To form control.
  • FIG. 2 shows a second exploded view of the invention Input device.
  • the viewing angle is now 180 ° rotated to Figure 1. Therefore, it is now possible to use the components also seen from the back.
  • This Plug 6 is used for connection to a line or a processing Electronics.
  • connection lug In Figure 3, the direct insertion by means of a connection lug shown.
  • the keyboard 1 has a terminal lug 20, which is stiff here. It is possible, however also to make them flexible.
  • the terminal lug 20 is in a socket 10 inserted to the electrical connection manufacture. This represents a particularly simple embodiment the connecting means.
  • the on the connecting lug illustrated interconnects are silver conductive paint and graphite produced.
