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.

Abstract: A non-electrical device (40) includes first and second half-housings which are produced in a plastic material, are joined fixedly to one another, define an axis along which a passage for an electrical conductor passes through the first and second half-housings, and delimit between them an internal volume, which is separated from the passage and which surrounds the passage all around the axis. The first half-housing incorporates, by moulding, mechanical reinforcing elements which extend substantially parallel to the axis in the internal volume until they are in contact with the second half-housing.

Abstract: A device comprises elements for measuring current, the elements being housed in a casing. The casing includes a first portion and a second portion made of plastic, welded to each other, which together define a housing for receiving the measuring elements. The first portion is opaque in order to absorb a laser beam for welding the portions, and the second portion is transparent in order to let the laser beam pass. The process for manufacturing the device includes a fitting step in which the measuring elements are fitted into the casing and an assembly step in which the portions of the casing are joined together using a laser welding process.

Abstract: A sensor for measuring current of the Rogowski-torus type including a carrier made of a magnetic materials and a secondary winding wound on the carrier in order to deliver an electrical signal representative of a current flowing in a conductor passing through the interior of the torus. The carrier is made essentially of a moulded rigid plastic material and includes at least one exterior recess distributed over the length of the body of the carrier. The recess includes at least two grooves that are separated by a partition. The protecting and measuring device and the electric circuit breaker include such a current sensor.
