  • Magnetic sensor and current measuring apparatus
    Patent number: 8952680
    Abstract: A magnetic sensor includes two sensor units with curved cores including meshing portions at front and base ends thereof and constructs a ring when the meshing portions mesh together. The meshing portions include main meshing portions that entirely overlap in a completely meshed state where the meshing portions overlap to the greatest extent. Auxiliary meshing portions that protrude inside and/or outside the ring are provided on the main meshing portions at the front and/or the base ends. In the completely meshed state, the auxiliary meshing portions do not overlap the main meshing portions or auxiliary meshing portions of the other core. In a non-completely meshed state where the main meshing portions partially do not overlap, the auxiliary meshing portions at least partially overlap the main meshing portions and/or auxiliary meshing portions of the other core.
