Abstract

A winding body for a magnetic assembly of a solenoid valve is disclosed, which comprises a base body, onto which a winding wire is wound, and two electrical connection domes, each of which has a first clamping gap with a first width, into which the winding wire wound onto the base body is inserted, wherein each of the winding wire ends rests on a contact surface of a wire support, which, in the direction of the corresponding winding wire end, is arranged behind the first clamping gap, and to a corresponding magnetic assembly, and to a corresponding solenoid valve comprising such a winding body, and to a corresponding method for winding the winding wire onto the winding body according to the disclosure. In order to receive the corresponding winding wire end, in the region of the contact surface of the wire support, a second clamping gap with a minimal second width is arranged behind the first clamping gap, the width being smaller than the first width of the first clamping gap. The minimum second width of the second clamping gap is adjusted to a diameter of the winding wire such that the corresponding winding wire end is fixed in the second clamping gap.
