Abstract
A magnet core for current sensors composed of a soft-magnetic alloy is disclosed which comprises at least two bent or buckled alloy band sections. A magnet core is also described with a primary leg and a secondary leg, whereby the secondary leg is formed of an alloy band section in single lay and of an alloy band section in double lay. The invention is also directed to a current sensor and to a method for manufacturing a magnet core.

A magnet core for current sensors composed of soft-metallic alloy composed of alloy band sections, said magnet core being composed of a first part of a magnet core and of a second part of a magnet core, the parts being shaped mirror-symmetrically relative to one another, each part having an intermediate section with a primary leg section extending at 90° from one end and at least two secondary leg sections extending at 90° a second end to form a substantially U-shaped structure with one of the at least two secondary leg sections having a different length than the other secondary leg sections, each part being arranged with end edges of the secondary leg sections of the first and second parts facing each other and at least partially abutting one another at a secondary side so that at least one pair of the secondary leg sections forms an air gap between meeting leg sections and one pair are abutting one another free of an air gap.
