Abstract:
An inductance element having a coil former and at least one wire winding arranged on the coil former, the coil former (1) having a cylindrical sleeve (1a) whose cylinder axis runs parallel to a winding axis (A--A) of the at least one wire winding, and at least two side walls (1b, 1c) arranged perpendicularly to the winding axis (A--A), and the cylindrical sleeve (1a) and the at least two side walls (1b, 1c) forming at least one winding space for the at least one wire winding (2, 3), whereinthe at least two side walls (1b, 1c) each have at least one shoulder (1d, 1e), which subdivide the at least one winding space into a non-constricted first region (B1) having a first length along the winding axis (A--A) and into a constricted second region (B2) having a second length along the winding axis, with the second length being less than the first length,and an electrical insulation (5), which rests and bears on the at least one shoulder (1d, 1e) of the at least two side walls (1b, 1c) and separates the non-constricted first region (B1) from the constricted second region (B2).
