Definitions

  • the invention relates to a position measuring device with contact sockets for electrical connections to electrically conductive grids on surfaces of relatively movable components - for example in the form of a material measure and a scanning plate of length or angle measuring devices - for direct contacting of the grids to the connections.
  • Measuring devices of this type are known. With the connection technology of such measuring devices deal z. B. DE-AS 12 63 327, DE-AS 12 98 299 and DE-GM 19 85 138.
  • connection of the electrically conductive measuring grid which is in the form of a conductor track, is made with the aid of cables which are soldered to the grid and led through bores to the rear of the carrier bodies or are guided around them to the rear.
  • connection sockets can be torn out when changing the contact pin.
  • the connection sockets can also not be provided with a screw connection, since there is no provision against rotation.
  • FIG. 1 shows a section
  • FIG. 2 shows a top view of an exemplary embodiment of the invention
  • a metallic scale body 1 carries on its surface a measuring graduation 2 made in the form of an electrical conductor etching technique in the form of an electrically conductive grid.
  • the mode of operation of measuring devices with such measuring divisions is adequately described in the prior art mentioned, so that it does not have to be discussed in more detail.
  • the measuring graduation 2 is isolated from the scale body 1.
  • In the scale body 1 there are slot-shaped recesses 3 and 3 'which are connected to through holes 4 in such a way that there are gradations due to the different dimensions. In each of these recesses 3 and 3 ', a part 5 and 5' of a two-part insulating body is inserted.
  • the insulating body part 5 is produced using plastic injection molding technology and has prismatic recesses 6, into which form-fitting contact sockets 7 are inserted.
  • the contact sockets 7 carry prismatic lugs 7 'into which the prismatic recesses 6 are fitted in such a way that a soldering lug 8 can be attached between the lugs 7' and the bottom of the recesses 6 and is in electrical connection with the measuring graduation 2.
  • the electrical connection is made by soldering 9.
  • the insulating body part 5 'molded from plastic has conical recesses 10 on its outer region.
  • the contact sockets 7 can be flared at their ends opposite the prismatic lugs 7 ', so that the expanded conical jacket 7 "after the plug-in assembly pulls the two insulating body parts 5 and 5' into the recesses 3 and 3 'in such a way that the contact socket is released 7 by rotation or by pulling out perpendicular to the scale body 1 is not possible without destroying the contact socket 7.
  • the through hole 11 arranged in the contact socket 7, which can be designed as a tapered bore, serves to receive a contact pin which provides the electrical connection to the evaluation electronics or to A screw connection is also possible with an appropriate design of the bore 11.
  • the contact socket 7 can also be galvanically gold-plated in the through bore 11, which contributes considerably to improving the electrical contact.
  • the measuring graduation 2 is provided with a protective lacquer layer to protect against negative influences.
