Stator assembly of a fuel injector, said stator assembly comprising electrical leads and a positioning feature, the electrical leads having two flat blade terminals (28, 30) protruding from the end of a cylindrical body, itself extending along a main axis and, a flat partition wall integral with the body, said partition wall extending between the blades that are symmetrically arranged on each side of said partition wall, the two terminals (28, 30) being adapted to engage about the main axis in electrical contact with two pins (40, 42) of a connector, said two pins (40, 42) being separated by an inter-pin distance; characterised in that the positioning feature preventing incorrect positioning of the terminals relative to the pins, comprising a first planar member integral to the partition wall and laterally extending on both sides of said partition wall, said partition wall and said planar member having together a "T" cross-section where the vertical leg of the T is the partition wall and the horizontal upper bar of the T is a first member of the positioning feature, said first member having a transverse front face which length extending perpendicular to the main axis is smaller than the inter-pins distance so that, during the engagement process with the connector having its pins extending substantially perpendicular to the main axis, an incorrect angular orientation of the stator assembly is prevented by the front face and, a correct angular orientation is assured by the engagement of the first member between the pins; the positioning feature further comprising a second member arranged around the leads and defining side axial faces so that, during the engagement process with a connector having the pins extending aligned with the main axis, a correct angular orientation of the stator assembly is assured by the engagement of each pin next to a side face. the electrical leads having two flat blade terminals (28, 30) protruding from the end of a cylindrical body, itself extending along a main axis and, a flat partition wall integral with the body, said partition wall extending between the blades that are symmetrically arranged on each side of said partition wall, the two terminals (28, 30) being adapted to engage about the main axis in electrical contact with two pins (40, 42) of a connector, said two pins (40, 42) being separated by an inter-pin distance; characterised in that the positioning feature preventing incorrect positioning of the terminals relative to the pins, comprising a first planar member integral to the partition wall and laterally extending on both sides of said partition wall, said partition wall and said planar member having together a "T" cross-section where the vertical leg of the T is the partition wall and the horizontal upper bar of the T is a first member of the positioning feature, said first member having a transverse front face which length extending perpendicular to the main axis is smaller than the inter-pins distance so that, during the engagement process with the connector having its pins extending substantially perpendicular to the main axis, an incorrect angular orientation of the stator assembly is prevented by the front face and, a correct angular orientation is assured by the engagement of the first member between the pins; the positioning feature further comprising a second member arranged around the leads and defining side axial faces so that, during the engagement process with a connector having the pins extending aligned with the main axis, a correct angular orientation of the stator assembly is assured by the engagement of each pin next to a side face.
