Abstract
A magnetic current sensor includes a magnetic circuit, an electrical winding, an insulating coil, and two leads respectively mounted on terminal parts of the coil and connected to ends of the winding. Each lead includes a main body, received in complementary fashion in a recess of the coil, and elongate along a body axis transversal to a coil axis. Each lead also includes two tongues protruding from a lateral face of the main body, each running from an end joined to the main body up to a free end. At their joining end, the tongues extend along respective tongue axes, which are parallel and each extend transversely to the coil axis and to the body axis. Between their joining end and their free end, the tongues are folded against the same lateral wall of the recess so as to keep the lead in position.
