Definitions

  • the invention relates to a polarized tongue contact relay according to the first part of patent claim 1.
  • Such a relay is known from DE-B-1 251 869.
  • This document relates to a protective tube contact relay, in which the contact system is melted into an evacuated glass bulb, over which the relay coil is pushed.
  • the coil must have a relatively large opening, which means that the magnetic field within the coil opening is no longer homogeneous across its cross section and therefore different magnetic forces act on the different tongues to be actuated by the coil field.
  • the relatively large cross-sectional area of the coil opening also means that the field line concentration is lower for the same total flow and therefore the magnetic forces acting on the individual tongues are weakened.
  • the fixed contact pieces are formed on metal tabs, which are soldered to the areas on the connection side on existing metallization strips on opposite surfaces of the ceramic bracket and in other areas connected to these areas by a double offset, close to the contact ends along opposite surfaces of a permanent magnet.
  • the contact distance between the fixed contact pieces is influenced not only by the thickness of the permanent magnet but also by that of the ceramic bracket and the exact shape of the double cranked metal lugs. If these three parameters are not exactly matched to one another, the fixed contact pieces facing each other are more or less spread apart, especially since their position is only defined in one direction by the permanent magnet located between them. Scattering in the distance between the fixed contact pieces, which is particularly important for the switching behavior, not only affects one relay to another, but also influences the synchronicity of the contacts of the same relay arranged next to one another.
  • the tongue contact relay which is also known from DE-B-1 614874, essentially corresponds to the known relay explained above, with the exception that it is not a polarized relay and the two fixed contacts do not have a permanent magnet but rather a non-magnetic intermediate body are separated.
  • the individual contacts are always at the same mutual distance from one another, this relates to the distance between adjacent contacts and not, as in the invention, the critical distance for the switching behavior of the opposite one another and which forms a changeover contact with a contact tongue Fixed contact pieces.
  • the invention has for its object to provide a polarized tongue contact relay, in which a simultaneous opening and closing of all contacts is ensured with the highest possible precision.
  • the measure of claim 2 ensures that the desired precision of the contact actuation can be achieved even with a two-part coil body, while the measure of claim 3 results in a further improvement in the synchronicity of the contact actuation.
  • a permanent magnet 1 preferably made of BaOFe, between four pole shoes 2a, 2b, 2c and 2d which are electrically insulated from one another.
  • a pair of pole shoes is encased with an injection-molded insulating part 7a, 7b, which has a relatively thin layer thickness d on its side facing the magnet and a much thicker layer thickness d 2 on the outside.
  • the layer thickness d should be thin so that there is the best possible coupling between the magnet and the pole piece, but on the other hand it should not be zero because it serves not only for insulation purposes but also as a magnetic air gap.
  • the extrusion coating has the advantage that a semi-cylindrical profile (FIG. 2c) can be formed, with the aid of which tolerances of the pole shoes with the fixed contact pieces or fixed contacts 4a, 4b, 4c and 4d relative to the guide grooves 9a, 9b, 9c, 9d in the bobbin 10 and its contact surfaces 20a, 20b.
  • the fixed contacts could also be replaced by appropriately cranked pole shoes; However, it is expedient to produce them separately, because they can then be subjected to a different surface treatment than is required for the pole shoes and their connections 8a, 8b, 8c, 8d because of the required contact conditions.
  • the two contact tongues arranged parallel to one another are preferably covered with a plastic part 6 for the purpose of parallel guidance. It does not matter whether this sheathing is carried out by ultrasonically welding two plastic films or by extrusion coating. In the case of overmolding, the center contact connections 5a, 5b could also be extrusion-coated with plastic after the spot welding with the contact tongues 3a, 3b in order to increase the security against loosening of the connection point, which is particularly stressed during the adjustment.
  • This part connected to a unit (FIG. 2a) is also positioned in the cutouts 9 of the coil body.
  • the relay assembly assembled in this way is inserted with its connections into the openings 15g of the base body 15 (FIG. 2e) and, after the permanent magnet 1 has been inserted, can be inserted between the two pairs of pole shoes (FIGS. 2c and 2d) positioned in the coil body 10 and after the electrical connection Connection of the coil wire ends with the coil connections 15c, 15d or 15e, 15f located in the base body 15 are adjusted at the connection point of the contact tongues 3a, 3b with the center contact connections 5a, 5b.
  • a ferromagnetic cap which differs from the final cap 16 only by an opening which allows access to the adjustment point.
  • the base body 15 has a shoulder 15b, on which the cap 16 is supported, and one or two openings 15a, which serve or serve both for filling with protective gas and for introducing potting compound 17.
  • the circuit 13 shown in FIG. 1 is used for synchronous contact actuation, even when the excitation voltage increases or decreases, a capacitor in series with the coil and an IC with a trigger and flip-flop according to DE-A-2 747 607 being provided.
  • the contact tongue is set to bistable behavior.
  • the trigger stage only switches at a specified voltage that is sufficient for both changeover contacts to respond suddenly.
  • the capacitor charges and blocks the flow of current through the coil.
  • a relay set to monostable would drop off again immediately, while the bistable relay remained in this position until the supply voltage was interrupted and the capacitor discharged via the coil winding and the flip-flop of the IC, thus instantly returning the relay contacts to their starting position.
  • the bistable relay is impressed with a monostable switching behavior, a synchronous actuation of both changeover contacts is guaranteed and, moreover, control energy is only required during the very short switch-on process of approx. 1 ms.
