Patent ID: 8330453

Claim:
A current detection apparatus for detection of a current flowing through a conductor ( 1 ) by detection of a magnetic field surrounding the conductor, comprising: at least one sensor element ( 3 ) provided on a carrier portion ( 4 ) for detection of the magnetic field, and a predetermined region (S) of the conductor ( 1 ), at which the at least one sensor element is arranged, wherein the conductor ( 1 ) in the predetermined region (S) has a plurality of conductor portions ( 11 , 12 ; La, Lb) which have the current to be measured flowing therethrough in the same direction and which are spaced from each other by a predetermined spacing and which form an intermediate space ( 2 ), and the carrier portion ( 4 ) is fitted into the intermediate space in such a way that the at least one sensor element ( 3 ) is arranged outside the intermediate space in adjacent relationship therewith in the magnetic field of the conductor ( 1 ), wherein the plurality of conductor portions ( 11 , 12 ; La, Lb) in the predetermined region (S) have two U-shaped formations having three substantially parallel conductor portion parts ( 5 , 6 , 7 ) with a central common conductor portion part ( 6 ) by which at least two field regions ( 8 , 9 ) are formed between the conductor portion parts, the conductor portion parts having open sides which are respectively oriented in opposite directions along a longitudinal extent (R) of the conductor ( 1 ).
