Definitions

  • the invention relates to a bobbin or a coil.
  • Coils are needed as electronic components for a variety of purposes.
  • both wire ends extend substantially radially on the inside of a flange, which serves for mounting on a printed circuit board.
  • the bobbin contains only one winding. The coils can therefore be used as a throttle. If there is now the need to accommodate a transformer with two galvanically separated windings or a reactor with a separate winding start and winding end on a spool core, then the winding must be wound over the radially outgoing wire ends of the first winding. Here is the danger of a rollover.
  • the invention is based on the object to provide a bobbin in which the risk of such a rollover no longer exists.
  • the invention proposes a bobbin with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
  • the serving for attachment to the circuit board flange thus has an opening which is disposed approximately where the top of the spool core extends. Depending on the coil to be wound up, this opening can also be offset somewhat further radially outward. In this way it is possible to guide the end of the coil wire or both ends of the coil wire through this opening on the opposite end face of the flange. A second winding then no longer crosses the beginning of the wire forming the coil.
  • the opening may be formed as a hole closed on all sides.
  • the opening than outgoing from the outer edge of the flange until at least just before reaching the outside of the spool core Slot is formed.
  • the end or the beginning of the wire forming the coil at the point where the outside of the coil ends lead to the opposite end face of the flange.
  • the invention also proposes a bobbin with a coil or two coils insulated from each other wound thereon, wherein at least one connecting wire of a coil is passed through the opening of the flange.
  • a layer of insulating material is arranged between the two coils, for example a strip of insulating material.
  • the FIG. 1 shows in a side view a coil which is wound on a bobbin.
  • the coil has a coil core which is covered by the winding 1 in the lateral representation.
  • the coil core is cylindrical.
  • a flange 2, 3 is formed, of which one of the two flanges, namely the flange 3, in FIG. 1 below, for attachment, for example, formed on a circuit board.
  • Both flanges have in their edge region two notches 4, which extend only slightly opposite to the edge 5 of the flanges inwards. Since the coil is to be electrically connected to the circuit board, lead the two ends of the 6 the coil winding 1 forming wire from the inner surface 7 of the mounting flange 3 to the opposite outer end face 8 of this flange.
  • both the upper flange 2 and the lower flange 3 each have two notches 4 which lead inwardly at diametrically opposite locations from the respective edge 5 of the flange.
  • the depth of the notches 4 is significantly lower than corresponds to the outer circumference of the coil 1.
  • the flange 3 has an opening in the form of an all-round closed hole 10 on a line connecting the two notches 4.
  • the end 11 of the coil winding 1 forming wire is passed through this hole 10 through to the outer end face 8 of the lower flange 3.
  • This hole 10 is arranged to start with the outside of the spool core 9.
  • FIG. 3 shows how the one end 6 of the coil winding 1 forming wire is guided through the outer notch 4 around the edge 5 of the lower flange 3 around.
  • FIG. 4 The perspective view of FIG. 4 that the in FIGS. 1 and 2 Lower flange 3 shows above, can be seen that the end 11 of the coil winding 11 forming wire is passed through the hole 10.
  • FIG. 5 and FIG. 6 show the bobbin from a different perspective. You can especially here in FIG. 5 See the arrangement of the hole 10, which leads from the inner surface 7 of the mounting flange 3 serving for this flange 3 to its outer end face 8.
  • FIGS. 8 to 12 illustrated embodiment differs from the previously discussed embodiment in that instead of a single hole 10 with a closed U m-fang the passage between the inner surface 7 of the mounting flange 3 and the end face 8 is formed as a radial slot 20.
  • a radial slot 20 may optionally facilitate the winding and housing of the end 11 of the wire forming the winding 1.
  • This slot 20 is also from the perspective views of FIGS. 10 to 12 to see.
  • the slot extends along a diameter, that is, exactly radially. But it is also conceivable that the slot is inclined. The important thing is that he reaches inside, the wire does not protrude beyond the outside of the coil winding 1 at the point where it is passed through the opening.
