An electromechanical actuator for actuating a parking brake of a motor vehicle, that includes: - an actuator housing including an open rear face and in which the following are housed, at least partially: -- an electric motor including a rear fairing and a rotating shaft of which a rear axial extremity bears an output pinion arranged axially beyond a rear transverse end face of the rear extremity of the fairing; -- a flexible printed circuit board placed on the fairing of the motor that includes an electrical connection part extending in a plane, referred to as the connection plane, that is generally transverse to the axis of rotation of the shaft of the motor and that has at least two electrical connection holes (114a, 114b); - and an electrical connector including at least two internal conductive pins, each of which has a conductive free rear electrical-connection end section (70, 70a, 70b), and in which: - the motor is placed in the housing by inserting it axially from back to front via said open rear face; - in the assembled position of the electric motor in the housing, each electrical connection section (70, 70a, 70b) extends axially through a related connection hole (114a, 114b) of the electrical connection part and is connected electrically to a conductive track formed on a rear face of this electrical connection part, characterized in that, before assembly of the motor in the housing, said electrical connection part extends in a plane, referred to as the assembly plane, that forms an acute angle (a) with said connection plane. - an actuator housing including an open rear face and in which the following are housed, at least partially: -- an electric motor including a rear fairing and a rotating shaft of which a rear axial extremity bears an output pinion arranged axially beyond a rear transverse end face of the rear extremity of the fairing; -- a flexible printed circuit board placed on the fairing of the motor that includes an electrical connection part extending in a plane, referred to as the connection plane, that is generally transverse to the axis of rotation of the shaft of the motor and that has at least two electrical connection holes (114a, 114b); -- an electric motor including a rear fairing and a rotating shaft of which a rear axial extremity bears an output pinion arranged axially beyond a rear transverse end face of the rear extremity of the fairing; -- a flexible printed circuit board placed on the fairing of the motor that includes an electrical connection part extending in a plane, referred to as the connection plane, that is generally transverse to the axis of rotation of the shaft of the motor and that has at least two electrical connection holes (114a, 114b); - and an electrical connector including at least two internal conductive pins, each of which has a conductive free rear electrical-connection end section (70, 70a, 70b), - the motor is placed in the housing by inserting it axially from back to front via said open rear face; - in the assembled position of the electric motor in the housing, each electrical connection section (70, 70a, 70b) extends axially through a related connection hole (114a, 114b) of the electrical connection part and is connected electrically to a conductive track formed on a rear face of this electrical connection part,
