Patent ID: 7355381

Claim:
Current sensor adapted to measure the value of the current flowing in a conductor ( 4 ), comprising a support ( 11 ) adapted to be positioned about the conductor through which the current to be measured flows, several components ( 6 ) sensitive to the magnetic field, disposed on said support ( 11 ) so as to be distributed about said conductor ( 4 ), and a processing circuit ( 9 ) receiving an output signal from said components ( 6 ) sensitive to the magnetic field, each component sensitive to the magnetic field comprising at least one first and one second terminal, the first terminals ( 6 a ) of all the components ( 6 ) sensitive to the magnetic field being connected by respective summing resistances ( 7 ) to a summing point ( 8 ) connected to a first input terminal ( 9 a ) of the processing circuit ( 9 ), the second terminals ( 6 b ) of all the components ( 6 ) sensitive to the magnetic field being connected to a second input terminal ( 9 b ) of the processing circuit, characterized in that all the summing resistances ( 7 ) are connected to a first conductor ( 31 ) connected to the summing point ( 8 ), all the second terminals ( 6 b ) of the components ( 6 ) sensitive to the magnetic field are connected to a second conductor ( 14 ) connected to the second input terminal ( 9 b ) of the processing circuit ( 9 ), the support ( 11 ) is constituted by a printed circuit, and the first and second conductors ( 13 and 14 ) are constituted respectively by first and second conductive tracks of the printed circuit which are arranged in zigzag on the printed circuit ( 11 ) so as to form a twist or a braid.
