Definitions

  • the invention relates to a bobbin and a coil for PCB assembly, consisting of a prismatic or cylindrical bobbin for at least one coil and from an integrally formed with the winding body foot part, which projects at least partially outwardly beyond the bobbin.
  • the coils located on a bobbin are usually connected to solder pins by connecting the wire ends of one or more coils to corresponding solder pins, wrapping them and then soldering them become.
  • the coil consists of a wide and relatively rigid sheet-metal strip, which is directly soldered to a conductor track of a printed circuit board.
  • An object of the invention is to simplify the construction of the winding material with simple mounting on a circuit board and thereby reduce costs.
  • wire guides are formed in sections of the foot part which lie opposite relative to the coil axis, resulting in increased stability of the winding material arranged on the printed circuit board.
  • the wire guides are formed as holes in the foot part, in which one end of the coil wire can be pushed through. This results in a simple way an immovable fixing of the solder pins.
  • the wire guides are formed as outwardly open grooves in the foot part, in which one end of the coil wire from the outside can be inserted. This design is especially useful when the wire is relatively stiff due to its diameter or its material properties, so that after winding a threading through holes could encounter difficulties.
  • At least one wire guide is formed as a bore in a section of the foot part and at least one wire guide is formed as an open groove in an opposite section.
  • the coil wire has a diameter of 1 to 4 mm and the coil wire is advantageously designed as a copper wire.
  • a bobbin 1 consists of a cylindrical bobbin 2 and an integrally formed with this foot part 3.
  • the entire bobbin 1 is made of plastic, such. Polyamide, for example, produced by an injection molding process.
  • plastic such as Polyamide, for example, produced by an injection molding process.
  • all materials can be used, which are suitable for the particular application of their electrical, thermal and mechanical properties.
  • the foot part 3 is rectangular in the present case and is - not seen in plan view - anywhere on the winding body 2 before.
  • the coil axis 1 opposite portions 3a, 3b, in which wire guides are formed, namely here two holes 4 in the one section 3b and two outwardly open grooves 5 in the other section 3a.
  • the grooves 5 are narrowed outwardly, so that a diameter suitable for a wire which is pressed into the grooves from the outside, there is a snap fit.
  • the holes 4 and the grooves 5 are parallel to the coil axis a.
  • FIGS. 4 to 6 show the wound bobbin according to FIGS. 1 to 3.
  • a winding or coil 6 is formed of two parallel wound wires 7, 8, e.g. from loaded copper wire.
  • the wires 7, 8 are inserted with their beginning through the holes 4 (Fig. 5), then the coil 6 is wound on the winding body 2 and then the ends of the wires 7, 8 are guided down and placed in the grooves 5.
  • the downwardly projecting ends of the wires 7, 8 are shortened so far that protrude a few millimeters above the holes 4 and grooves 5 and thereby form solder pins 9 With the help of these solder pins 9 then the winding material can be mounted in a known manner on a printed circuit board 10 and soldered, which is indicated in Fig. 5.
  • the otherwise customary connecting wires for the soldering pins (pins) in the invention are formed by the winding wire of the coil and pass directly, integrally into the soldering pins.
  • the coil 6 is completeness completeness by an E-core 11, which consists of two halves, which are glued in the air gap spacers 12 made of plastic, which mechanically fix the two core halves and the Winding the coil 6 can optionally be fixed with adhesive, such as a synthetic resin. Due to the asymmetrical arrangement of the solder pins 9 a correct mounting of the entire winding material on a circuit board 10 is ensured.
  • the coil 6 is a single winding, but double wound to allow a high current with reduced spin effect and modest wire diameter.
  • all variants of coils or windings are possible.
  • two connections or solder pins are sufficient for a single, single-wound coil.
  • a coil former suitable for this purpose is e.g. shown in Fig. 7, wherein in the foot part 3, only a groove 5 and a bore 4 are provided as wire guides.
  • Fig. 8 shows an embodiment in which the winding body 2 has approximately square cross-section, wherein in the foot part 3, two grooves 5 and two holes 4 are formed as wire guides.
