Abstract
The invention relates to an coil former and at least one wire winding arranged on the coil former, the coil former (,) having a cylindrical sleeve (,) whose cylinder axis runs parallel to the winding axis (A—A) of the at least wire winding, and at least two side walls (,) arranged perpendicularly to the winding axis (A—A), and the cylindrical sleeve (,) and the side walls (,) forming at least one winding space for the at least one wire winding (,). According to the invention, the at least two side walls (,) each have at least one shoulder (,), which subdivide the at least one winding space into a non-constricted first region (B,) and into at least one constricted second region (B,). In addition, the inductance element has electrical insulation (,), which bears on the at least one shoulder (,) of the side walls (,) and separates the non-constricted first region (B,) from the at least one constricted second region (B,).
