Definitions
- the document DE 101 96 259 T1 relates to the arrangement of filling material in the passages of an electronic substrate, such as e.g. by placing an electrically conductive, thermally conductive or non-conductive paste in and on electronic boards, ceramic substrates and "packages".
- the stray magnetic field of a conductor which passes through the coil core is reduced. It is particularly advantageous if all the first turn sections pass through the coil core, since then the lateral stray field of the coil is greatly reduced and the external magnetic field generated by the coil concentrates on the end faces of the coil. Another advantage here is that the homogeneity of the magnetic field, which is generated at the end faces in the outer region of the coil, is improved.
- inductive sensors in particular inductive proximity sensors.
- coils according to the invention bring greater resilience and reliability, since it can be dispensed with the usual air gap in inductive sensors.
- air gap is disadvantageous that its dimensions may vary due to temperature fluctuations or due to mechanical stress.
- miniaturization of the coil is not limited by the size or manufacturing tolerances of the cavity, since preferably all first turn sections through the cavity and thus through the core material pass, so that the enclosed by the first turn sections Kernmateria! forms the spool core.
- the invention turns away from the paradigm that the core material must be completely inside the coil.
- the cover layer 122 bridges the open side 108 of the cavity 106 and compensates for any unevenness in the transition region between the surface 02 and the surface of the paste on the open side 108, so that a planar surface 124 results, which covers the surface 102 over the entire surface.
- FIG. 10 shows, as an alternative to FIG. 2, a rectangular configuration of the cross section of the cavity 106 and FIG. 1 shows, as a further embodiment, a cavity 106 with a semicircular profile. Other geometric shapes for the cavity 06 are also possible depending on the application.
- the diameter of the coil 140 may be less than 5 mm, such as 3.5 mm.
- This structure is then applied with a contact pressure and heated to a temperature of, for example 70-80 ° C. This can be done in a vacuum.
