Definitions
- the innovation relates to a bobbin for winding with winding wire.
- bobbins for producing the winding are known for various variants of components with cores and at least one winding.
- Such bobbins are in particular in cores from stamped sheets or material cores (made of, for example, ferrite or various powder materials on iron or iron alloy) with divided core shapes such as E cores according to IEC 61246 or RM cores according to IEC 60431 in each of various embodiments used.
- connection pins are laterally offset with respect to the winding space of the copper coil and are usually arranged in two rows along the longitudinal axis of the component. mentes are arranged. Both of these constructions have in common that the winding of the copper wire must be done in a narrow area between the bobbin lower edge and the board surface to be populated and the space available for this is very limited.
- the known constructions quickly reach design limits due to the copper cross sections of the winding wire required there.
- This problem is further exacerbated for devices that are manufactured using copper wire to optimize the RF characteristics, since here the wire cross section through the segmentation in individual cores is clearly above that of a cross-sectionally identical single enameled wire and, secondly, especially at
- the use of stranded wire with very thin single cores (eg ⁇ 0.15 mm) with a simple looping of the connecting pin can not achieve sufficient strength of the connection, so that the stranded wire usually reaches at least twice around the respective terminal pin must be looped which of course increases the space required for the winding of the wire on.
- the novelty is therefore based on the task of proposing an improved bobbin.
- the bobbin according to the invention is optimized on the one hand with regard to the space requirement of the component and offers the Furthermore, the possibility of easier winding even thicker stranded wires to the pins.
- the bobbin which is usually produced by injection molding, is produced in at least two separate partial bodies, of which the first partial body serves as a base or support plate for the connection pins and the second partial body serves as a winding support for supporting the component winding.
- Other bodies may be provided as needed and function.
- the part body serving as a winding support is first wound with the required amount of enameled wire or stranded wire, and the wire ends are led out to the outside of the winding support through an opening on the side of the reel body into which the Anwickelloche are later inserted.
- the two body parts of the bobbin are brought together so that the pins are inserted through corresponding openings in the winding support.
- the bottom plate is fixed by corresponding locking fasteners on the winding support.
- the innovation also allows voluminous solder connections with more than one loop and using HF
- a further advantage of the proposed design is that the terminal soldering of the coil winding is spatially separated from the mounting soldering of the component in the printed circuit board. A re-softening and in extreme cases a loosening of the connection of the winding wire to the soldering pin during the soldering of the component in a printed circuit board can thus be reliably excluded.
- Fig. 1 a bobbin without winding in the unassembled state
- Fig. 2 a bobbin without winding in the assembled state
- Fig. 2 a mounted bobbin without winding in an RM core.
- the basic structure of a bobbin 1 according to the invention is shown in FIG. 1.
- the bobbin 1 consists of two partial bodies, namely a contact carrier 2 designed as a base plate and a winding support 3 for receiving a winding consisting of winding wires.
- the winding carrier 3 has a cylindrical winding section 4 and a ceiling plate 5 extending perpendicularly thereto with two lateral guide segments 6, 7.
- the winding support 3 has a parallel to the ceiling plate 5 arranged base plate 13, for attachment to the bottom plate 2, on.
- the winding section 4 is thus bordered on two opposite sides for better retention of the winding.
- pins 10 are used, which have on the bottom of the bottom plate over the standard length of 5 mm (about 1/5 inch) for attachment to a circuit board.
- the pin length on the opposite side of the base plate 2 depends on the height of the winding carrier 3.
- the pins 10 protrude beyond this by approx. 3 - 6 mm.
- the winding support 3 is first wound with the required amount of enameled wire or strand and the wire ends are guided freely through the openings 14 in the guide segments. After completion of the winding, the two body parts 2, 3 of the bobbin 1 are brought together so that the straight pins 10 are inserted through the openings 11 in the guide segments 6, 7 of the winding support. During the final assembly of the two partial bodies, the base plate 2 is fixed to the winding carrier 3 by corresponding, in particular latching, connecting elements (not shown).
- FIG. 3 shows the assembly of a bobbin 1 using an RM core 12.
