Definitions

  • the invention relates to a coil for an electromagnetic relay with response delay with a coil tube for receiving a core and two flanges having flanges connected to the ends of the coil tube and with a coil applied between the flanges on the coil tube, the core and the Winding a short-circuit tube made of copper or another material with good electrical conductivity is arranged.
  • a coil of the type mentioned with a short circuit Pipe made of copper is described for example in DE-OS 1 514 717.
  • the coil body in several parts and to assemble it, in order first to be able to slide a copper tube onto the core tube of the coil body and then to be able to connect the flange to the core tube.
  • this not only means an increased outlay on parts and manufacturing steps, but also the winding space is reduced by the additionally pushed-on copper tube.
  • the object of the invention is to provide a coil for a relay and a relay itself, in which a response delay is achieved with a short-circuit tube without the winding space or the other dimensions of the coil and the relay having to be changed thereby.
  • this object is achieved in that the short-circuit tube forms the load-bearing part of the coil tube and is connected at the ends to the insulating material of the flanges and that only a thin insulating layer is provided between the short-circuit tube and the winding in the area between the flanges.
  • a solid short-circuit tube made of copper or a comparable material thus represents the supporting element of the coil former.
  • This tube replaces the electrically and magnetically inactive plastic coil tube, as is normally present in coil formers.
  • the winding area or the core cross-section are not changed by this. Due to the small diameter that can be achieved in this way and the length over the entire area between the two coil flanges, an AR value (resistance value of the short-circuit winding) in the order of magnitude of the excitation winding can be achieved for the short-circuit tube. With this, response delays of up to two times compared to the coil can be achieved without a short circuit.
  • the short-circuit tube is encased at the ends by embedding, in particular by injection, with the material of the coil flanges.
  • the tight fit between the short-circuit tube and flanges can also be improved by appropriate surface design in this area, for example by knurling the short-circuit tube.
  • a thin spray skin made of the same plastic as the flanges can serve as the insulation layer between the short-circuit tube and the winding wire, for example.
  • Other options are wrapping with a plastic film or subsequent painting of the short-circuit tube.
  • the drawing shows a partly schematic, partly also a sectional illustration of a relay for switching high currents, as is used, for example, in motor vehicles.
  • a relay for switching high currents, as is used, for example, in motor vehicles.
  • it has a base 1 with tabs 2 and a coil 3, which is fastened on the base and serves as a base body for the entire relay system.
  • a yoke 4 with an armature 5 and a contact spring 6 is arranged on the coil, the latter also serving as an armature return spring.
  • the contact piece 7 at the free end of the spring 6 interacts with a mating contact element 8 anchored in the base.
  • a cap 9 forms together with the base 1 a closed and sealable housing.
  • the relay is constructed in a known form.
  • the coil 3 has a coil tube in the form of a short-circuit tube 10 made of copper, which is encapsulated at the ends with a flange 11 and 12, respectively.
  • a short-circuit tube 10 made of copper, which is encapsulated at the ends with a flange 11 and 12, respectively.
  • other materials with good electrical conductivity can also be considered, such as copper alloys or aluminum.
  • a thin insulation layer 13 is provided as a spray skin or as a subsequently applied film.
  • a winding 14 is applied in the usual way.
  • a core 15 is also inserted into the coil tube in a known manner, which is connected to the yoke 4 at one end and forms a pole plate 16 for the armature 5 at the other end.
