Patent ID: 7375507

Claim:
An assembly group for current measurement, consisting of: a conductor plate and a measuring element; the conductor plate having a flat surface with three cuts wherein the first and third cut start from a first edge of the conductor plate and wherein the second cut starts from an opposing second edge of the conductor plate and is arranged between the first and third cut, so that a first and a second conductor section are formed in the conductor plate wherein a current direction in the second conductor section is opposite to a current direction in the first conductor section, the measuring element having a first and a second magnetic field sensor that are sensitive to a component of the magnetic field that runs parallel to the flat surface of the conductor plate and perpendicularly to the current direction in the first conductor section, wherein the first and the second magnetic field sensor comprise magnetic field sensing elements that are formed in at least one semiconductor chip, that comprise a ferromagnetic material located on an active surface of the at least one semiconductor chip and that are encapsulated in a same housing or in separate housings, the at least one semiconductor chip comprising electronic circuitry for the operation of the magnetic field sensitive sensing elements, wherein the measuring element is placed on the flat surface of the conductor plate in such a way that the first magnetic field sensor is located above the first conductor section and the second magnetic field sensor above the second conductor section.
