Definitions

  • the invention relates to a holder for an electrical coil with E-core halves made of magnetic material, in particular EC core halves with round central legs and with a coil body with a hollow cylindrical Vickel carrier, which is pushed onto these central legs and carries solder tabs integrally formed on its end faces.
  • the present invention has for its object to provide a holder for an electrical coil of the type mentioned, which is simple in design, is characterized by a high resistance to shaking and is also easy to assemble.
  • the invention provides for a holder of the type mentioned screw bolts, which abut one end directly or indirectly against an outer surface of a first E-core half and with their other ends formed with screw threads through bores of a strip-shaped element and with are screwed, the strip-shaped element abutting against an outer lateral surface of the second E-core half parallel to said outer lateral surface.
  • a further strip-shaped element with bores through which the screw bolts are guided can be arranged between the angled ends of the screw bolts and the adjacent outer lateral surface of the first E core half.
  • a secure mounting is also ensured if, instead of this second strip-shaped element, the screw bolts are replaced by a U-shaped bracket, whose free ends also have screw threads and whose parallel parts are guided in the grooves of the E core halves.
  • This holder is designed so that the two E-core halves are not pressed together in the middle, but on the outside.
  • This electrical coil is fastened to a circuit board by means of the screw bolts or wire clips, the ends of which with screw threads are guided through openings in the circuit board and screwed to the latter.
  • the solder connections of the coil former are plugged into the printed circuit board and soldered there or point upwards by 180 ° and are connected by means of soldered wires or plug connections.
  • the EC core halves 1, 2 according to FIG. 1 have round central limbs 15 and grooves 9. On this central limb is a hollow cylindrical one, designated 17 in FIG. 2 Slid on a bobbin 16. On the flange-like ends of the winding carrier 17, solder tab strips 18, which serve as carriers of solder tabs 19, are integrally formed. The solder tails 19 are optionally contacted with the ends of a winding 20.
  • FIG. 3 shows a U-shaped bracket 14.
  • the mutually parallel parts of the bracket 14 are guided in the grooves 9 of the EC core halves 1, 2.
  • the free ends of the bracket 14, which are designed with screw threads, penetrate bores 5 of a strip-shaped element 3 which bears against the groove-free outer surface of the EC core half 2.
  • the final and shake-proof assembly is then carried out by screwing to a circuit board.
  • the length of the free ends of the brackets is chosen so that these ends penetrate the corresponding bores formed in the circuit board and can additionally be screwed to the circuit board.
  • the hollow cylindrical winding carriers are aligned perpendicular to the circuit board.
  • the holder according to FIG. 3 can, as shown in FIG. 5, be replaced by a holder which has two screw bolts 6 with hook-shaped ends and an additional strip-shaped element 4. As far as this bracket contains the same parts, they are the same Reference numerals.
  • the bolts 6 or brackets 14 can be guided in mutually parallel bores of the E-core halves 1, 2 instead of in grooves 9.
  • a holder is also conceivable, in which the central web of the bracket 14 bears against a further strip-shaped element which is arranged between the adjacent outer jacket surface of the first E core half 1 and the bracket and is provided with bores for the passage of the bracket.
