Definitions

  • the invention relates to an electrical coil, and in particular to an electrical coil suitable for use in printed circuit boards with a coil body with at least one coil body flange with soldering lugs and with magnetizable cores, in particular ferrite cores, which are pushed or plugged onto the coil body.
  • the invention has for its object to provide for an electrical coil of the type mentioned above, a possibly also automatically effortlessly mountable, the exact alignment of the cores with respect to one another and to the coil former, simple holder which e.g. When using E-cores, pressure is exerted essentially only on the abutting outer legs of the E-cores and thus an undesirable air gap between the facing end faces of the outer legs is largely avoided.
  • the invention provides for an electrical coil according to the preamble of claim that against each core there is an angled spring at its ends, in particular leaf spring or resilient wire bracket, under the effect of which the cores are pressed against each other, and that the ends of the Springs and each bobbin flange are formed with projections or perforations which snap into one another when the springs are assembled.
  • the coil former flanges can optionally be provided with projections and the springs with openings or vice versa.
  • the arrangement of the projections or - if this is expedient - the openings on the coil former flange should advantageously take place on surfaces of the coil former flanges which are at least approximately parallel to the angled ends of the leaf springs. Provided that such inclined surfaces are missing, it is advisable to integrally form projections on the bobbin flanges that are in a common plane with the bobbin flanges.
  • the coil former 1 has integrally molded coil former flanges 2 with solder tab strips 6 on the front ends of the winding former, which are supplemented to form rectangular frames 3 and are equipped with electrical connecting pins 7.
  • projections 15 are integrally formed on the narrow sides of these frames and are turned outwards.
  • the central slugs 9 of the E core halves 8, consisting of ferrite dip into the hollow cylindrical interior of the winding former of the coil former 1 and penetrate the openings 4 in the frame 3 with their outer legs 10.
  • the leaf springs 13 are preferably only against the areas of the surfaces 12 of the E-core halves 8 which are adjacent to the outer legs 10, so that generally only the outer legs 10 of the E-core halves are urged against one another.
  • the perforations 16 formed in the angled ends 14 of the leaf springs 13 engage in the projections 15 and thus ensure a safe hold of the leaf springs, and consequently a sheet secured arrangement of the E-core halves 8.
  • the projections 15 can also be integrally formed on the end edges of the possibly rectangular end flanges 2.
