立の際に発生する。2. Description of the Related Art When an open type iron core is used, the coil winding is wound on a winding frame made of a plastic material and is entirely fitted on the iron core, as in the case of a closed type iron core. . The coil thus produced is then molded to secure and protect its components. If maintaining a certain inductance value or external magnetic field distribution is a problem in its use, this depends on the exact positioning of the winding with respect to the core. In the case of short coils, this placement effect is even greater than the effect caused by variations in the material permeability. This disposition variation actually occurs during winding and during assembly of the components due to mechanical tolerances in the manufacture of the core and reel.

【０００５】これによりコイル巻線が鉄心に関して一定

われる。FIG. 1 shows a cross section of the winding support 1. The winding support 1 is in this case formed with two protrusions 2, 3 which surround a chamber 4 in which the winding of the coil is mounted.
Since the winding is directly attached by forming the winding support 1 with a coil integrated in the iron core, there is no effect on the consistency of the magnetic action of the mechanical tolerances of the divided components. The winding support 1 is produced by simultaneous production of the iron core and the winding frame, preferably by known injection molding.

もできる。The winding support 1 is preferably formed of one component, for example FPC. However, the winding support 1 can also consist of at least two different constituents, all of which are magnetic or magnetizable, at least one of which is an electrically insulating, non-magnetic material.

場合よりも好ましくないものと考えられるべきである。
何故なら、両突起部を磁性材もしくは磁化可能な材料で
形成することにより、磁力線の集中、従って磁界の減衰
が予想されるからである。In a conventional winding support consisting of two parts, one of the protrusions 2 or 3 belongs to the winding frame and is therefore made of a non-magnetic material. Therefore, the magnetic field distribution around the coil made of the winding support according to the invention should normally be considered less favorable than in the case of a conventional winding support consisting of two parts.
This is because by forming both protrusions with a magnetic material or a magnetizable material, concentration of lines of magnetic force, and thus attenuation of the magnetic field, is expected.
