Definitions
- the invention relates to a Spuleh redesign and a coil for PCB assembly, consisting of a prismatic or cylindrical winding body for at least one coil and from a integrally formed with the winding body foot part, which at least partially protrudes outwardly beyond the winding body.
- 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.
- connection wires for the at least one coil formed by the winding wire are formed with their ends as solder pins, which are received in wire guides of the foot part and held therein.
- the invention can be omitted in the manufacture of the bobbin with the coil, thus the winding material, a single operation, namely the soldering of the coil with its own solder pins. Since the ends of the winding wire are received in the wire guides of the foot part and held therein, there is a defined distance of the solder pins according to the holes provided on the circuit board.
- wire guides are formed in sections of the foot part which lie opposite relative to the coil axis, which results 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. It is advantageous in view of the desired securing of the solder pins when the grooves are narrowed to the outside, wherein the coil wire snaps when inserting.
- 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.
- FIG. 1 is a plan view of a first embodiment of the invention
- FIG. 2 is a side view in the direction of arrow II of FIG. 1,
- FIG. 3 is a side view in the direction of arrow II of FIG. 1,
- FIG. 4 a coil former according to FIGS. 1 to 3, wound and provided with a core in plan view, FIG.
- FIG. 5 shows the arrangement bobbin-coil-core as in FIG. 4, but soldered in side view on a printed circuit board, FIG.
- FIG. 6 is a view like FIG. 5, but seen from the opposite side
- FIG. 7 is a plan view of another possible embodiment of a bobbin in the context of the invention, and 8 shows a further embodiment of a bobbin in a plan view, similar to FIG. 7.
- a bobbin 1 consists of a cylindrical bobbin 2 and a foot part 3 integrally formed therewith.
- the entire bobbin 1 is made of plastic, such as e.g. Polyamide, for example, produced by an injection molding process.
- plastic such as e.g. 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 above 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 suitable diameter 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. made of damaged 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.
- solder pins 9 the winding material can then 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 completed by an E-core 11, which consists of two halves, wherein in the air gap bonded spacers 12 are made of plastic, which mechanically fix the two core halves.
- the winding of the coil 6 can optionally be fixed with adhesive, for example 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. In the context of the invention, all variants of coils or windings are possible. Of course, two connections or solder pins are sufficient for a single, single-wound coil.
- a coil body suitable for this purpose is shown for example in FIG. 7, wherein in the foot part 3 only a groove 5 and a bore 4 are provided as wire guides.
- coil is intended to include tapped windings as well as multiple windings of a transformer or transformer.Also in these cases, three or more solder pins will be required , wherein in the foot part 3, two grooves 5 and two holes 4 are formed as wire guides.
