Definitions
- the present invention relates to a coil former for an inductive component and an inductive component
- the inductive component is used in a stereo system.
- the desired setpoint is called “adjustment” or “tuning”.
- a coil former is designed as a carrier for a winding wire of an inductive component.
- the coil body has a base body which is wrapped at least in some areas with an electrically insulating film.
- the diameter of the coil body is selectively increased.
- the inductance can be targeted
- the main body of the bobbin is formed in one embodiment from a non-magnetic material.
- the inductive component can thus be designed as an air-core coil, that is to say it can have no magnetic core around which the winding wire is wound.
- the coil body thus functions purely as a carrier for the winding wire, but not for guiding the magnetic flux.
- the inductance is particularly dependent on the geometry, in particular the diameter of the coil, so that precise fine-tuning is possible by changing the diameter.
- the thickness of the film is significantly less than 1 mm.
- the film is, for example, a maximum of 100 ⁇ m thick.
- the thickness of the film can be between 10 and 40 ⁇ m.
- the base body can be formed from a magnetic material.
- it can be a ferrite core.
- the film is, for example, helically around the
- Windings of the film around the base body can be determined depending on a nominal value of the inductance.
- the number of turns is varied between one turn and four turns.
- the film is arranged in particular in such a way that the
- Winding of the winding wire can be arranged over the winding of the film.
- the geometry of the winding of the film corresponds to the geometry of the winding of the
- the winding of the film is preferably shorter than the winding of the wire.
- the wire winding can completely cover the length of the film and extend beyond the film.
- the winding wire can also completely cover the width of the foil.
- the maximum possible, effective length is referred to as the length of the film at which the film is present below the entire winding and thus the entire winding over an enlarged diameter
- the film is applied to half of the possible maximum effective length, then the winding is applied and the inductance of the component is measured. Depending on the measured
- Inductance value is then reduced or increased in the production of further components, the length of the film.
- the film in the resulting component does not extend over the entire length of the base body, in particular not over the maximum possible, effective length of the film.
- the film extends over a maximum of two thirds of the length of the base body or the maximum possible effective length.
- the film extends over a minimum of a third of the length of the
- Basic body or the maximum possible, effective length It is also possible that the film extends initially or over the entire maximum possible, effective length in the case of the coordinated component, or that no film is present.
- the film can be applied to the base body in a single layer. However, to change the thickness further, the film can also be applied in multiple layers. To adjust the inductance, a certain number of layers of the film is initially present, for example, and one or more layers are then used depending on the inductance value measured Layers removed or added. There can also be foils with different thicknesses and it can be used for
- Fine tuning the thickness of the foil can be varied.

- a combination of changing the length and changing the number of layers or thickness of the film is also possible.
- the film is formed from a non-magnetic material.
- it can be a plastic material.
- the film can have the same material as the coil body. Thus, the film is only used to enlarge the diameter of the coil body, but not to guide the magnetic flux.
- the coil body can have a recess in which the film is arranged.
- the recess is designed for the exact placement of the foil and / or for the exact placement of the winding wire.
- the recess is, for example, designed to be circumferential, in particular the recess extends helically around the base body.
- the recess can only run around the base body in sections or continuously around the base body.
- the recess has at least two turns, in particular continuous turns.
- the depression extends, for example, at least over the entire length of the film.
- the recess is not only for the placement of the film, but also for
- the depression preferably extends over a large part of the length of the base body.
- the depression has lateral boundaries so that the film and / or the winding wire are guided so that they cannot slip perpendicular to their course in their main direction of extent.
- the lateral boundaries can be formed by the material of the base body.
- the depressions can be formed directly during the production of the base body, for example in an injection molding process.
- the film is only slightly wider than that
- the film can also have the same width as the depression or be slightly wider than the depression. In this case, the film can be fastened in the recess by clamping.
- an inductive component has the one described above
- the film is at least regionally, in particular over a region of the length of the
- Winding wire arranged between the winding wire and the base body.
- the outer diameter of the coil body and thus the inner diameter of the winding is increased at least in some areas. This leads to an increase in the inductance of the component.

- Boundaries are widened by pressure and heat, so that the foil and the winding wire are at least partially enclosed by the boundaries in the radial direction.

- the length is gradually increased or decreased until the desired target value is reached.
- the number of turns is changed in a range from 1.00 to 4.00 turns.
- the change in length is, for example, less than one turn, for example 0.01 turns.
- a coil former for an inductive component has a
- the delimitation is designed in particular to guide a section of the winding wire in a central region of the winding, that is to say it is a Section to which at least one further turn of the winding wire is adjacent on both sides. It is therefore not an edge section of the winding.
