Abstract
A bobbin for a solenoid. The bobbin includes a main body for receiving wire windings of a wire, wherein the main body extends hollow-cylindrically along an axial direction and has a wall having a wall thickness, wherein at least one opening is formed in the wall, wherein the wall thickness becomes smaller along the axial direction toward the opening, and/or wherein the geometric shape of the opening is designed to vary along the axial direction, at least in sections. A solenoid having such a bobbin and at least one wire winding, is also described.
