Abstract:
Arrangement for implementing a magnetic circuit on a circuit board, which arrangement includesa printed circuit board (PCB) wherein a conductive pattern of an inductive circuit is formed as well as openings (H1-H3) through the circuit board close to the conductive pattern,two ferrite pieces (F1, F2), at least one of which can be fitted into the openings so that the pieces can be pressed against one another from opposite sides of the circuit board, anda mechanical clamp (CL2, CL3, CL4) which can be fitted around the ferrite pieces to lock them to each other, whereby the clamp extends around ferrite pieces located on both sides of the circuit board, characterized in thatspring-like protrusions (14-16) are formed in the clamp and they are fitted in relation to the openings (H1-H3) in the circuit board so that they press against the inner edges of the openings when the clamp is in its position around the ferrite pieces.
