Stator for an electric machine, mold for producing a stator, method for producing a stator and electric machine for a vehicle

A stator for an electric machine, comprising:

• a stator core which has an axial end side;
• a plurality of shaped conductors which protrude from the stator core at the end side and which each have, at the end side, at least one end portion comprising a free end of the shaped conductor, wherein arrangements of at least two of the end portions are connected to one another in an electrically conductive and mechanical manner in such a way that each arrangement forms a connecting portion which has a first cross-sectional area that lies in a predefined cross-sectional plane and that has corner portions and side portions lying between the corner portions;
• and
• a plurality of insulation elements which each envelop at least one of the connecting portions and which are each formed from an electrically insulating material;
• wherein each insulation element has a second cross-sectional area which lies in the cross-sectional plane and which has, for each corner portion of the first cross-sectional area of the connecting portion enveloped by the insulation element, an additional area and sides lying between the additional areas, wherein a respective one of the additional areas extends further in a direction pointing away from the first cross-sectional area than the sides which adjoin the additional area.
