Definitions

  • the invention relates to a coil for an electromagnetic relay with a coil body, which forms a coil tube, which is cylindrical in its basic form as a carrier for a winding package, and two flanges as respective axial boundaries of the winding space.
  • a round magnetic soft iron core is often used for flux guidance within the field winding, which is why the coil former, which is made of insulating material and carries the winding, also has a coil tube in the shape of a cylinder.
  • the winding made of thermoplastic coated copper round wires is applied to this coil tube under tension in the winding space between the two flanges, so that the winding package initially sits firmly and immovably on the coil tube.
  • the winding ends are connected, for example, to connecting wires in the coil flanges, with strain relief usually being provided so that the winding ends under tension do not tear under changes due to temperature or mechanical stress.
  • the winding package on the coil tube is loose and can be moved in the axial and radial directions. Due to additional external forces such as vibrations, shock loads and temperature changes, there is a risk of the winding wire ends between the winding and the connection ends being interrupted, which are, for example, firmly anchored in a coil former flange. Such vibrational stresses occur in particular then when a relay is installed in a moving device, for example in a motor vehicle.
  • the object of the invention is to design a coil of the type mentioned in such a way that such external forces cannot lead to displacements or twists of the winding, even when the winding package shrinks, and thus endanger the winding ends.
  • this object is achieved in that at least one projection engaging in the winding package is formed on the outer circumference of the coil tube.
  • a plurality of nose-shaped or conical projections is preferably arranged in a common radial plane distributed over the circumference of the coil tube. The arrangement of the projections in a single radial plane prevents stresses within the winding package from being caused by the projections.
  • the outer circumference of the coil tube has at least one flattened portion from which a protrusion in the form of a bead protrudes.
  • This bead can be formed, for example, as a continuation of the circular cross section of the other coil tube circumference.
  • the coil shown in FIGS. 1 and 2 has a coil body 1 which has a coil tube 2 and two flanges 3 and 4.
  • the coil tube 2 has a circular cross section and an inner bore for receiving an iron core, not shown.
  • a winding 5 made of thermoplastic coated copper wire is wound on the outer circumference of the coil tube 2. The beginning of the winding 6 is first fastened to a connecting pin 7 which is anchored in the coil flange 3.
  • a compact winding package 5 is formed by baking the wire insulation, which can sit loosely on the coil tube 2 after a certain time.
  • the coil tube 2 has conical knobs 8, which are arranged near the start of the winding 6 on a common radial plane. These knobs 8 already drill into the winding package from the inside when the winding is applied and thus prevent later movement. Since the knobs 8 are in the vicinity of the coil flange 3, the shrinking winding package is pulled in the direction of the end of the winding 6 at risk, so that stress in the longitudinal direction is avoided.
  • FIGS. 3 and 4 A somewhat modified embodiment is shown in FIGS. 3 and 4.
  • a coil former 11 has a coil tube 12 with flanges 13 and 14.
  • a winding 15 is applied to the coil tube, with a winding start 16 being fastened to a connecting pin 17 in the coil flange 13.
  • the coil tube 12 has lateral flats 18, so that the winding package 15, which is adapted to the outer circumference of the coil tube, cannot be rotated on the coil tube even with a certain shrinkage.
  • the flattening 18 is interrupted in each case by a bead 19 in the vicinity of the start of the winding 16, in which case the bead is designed as a continuation of the circular jacket surface of the coil tube 12.
