  • Excitation core, sensor head, and current sensor
    Patent number: 10782321
    Abstract: An excitation core includes an annular strip-shaped magnetic substance, in which both ends of the strip-shaped magnetic substance are overlapped in a thickness direction and are in contact with one another. A sensor head includes: this excitation core and a magnetism collecting body. The magnetism collecting body includes a strip-shaped first magnetism collector and a strip-shaped second magnetism collector, the first magnetism collector having both ends thereof in contact with both ends of the second magnetism collector to form the annular magnetism collecting body, the magnetism collecting body being disposed on an inside or an outside of the reinforcing body.
    Type: Grant
    Filed: March 16, 2018
    Date of Patent: September 22, 2020

  • Excitation core, sensor head, and current sensor
    Patent number: 10345341
    Abstract: An excitation core includes a first strip-shaped magnetic substance and a second strip-shaped magnetic substance. The first strip-shaped magnetic substance has both ends mutually overlapped with and mutually in contact with both ends of the second strip-shaped magnetic substance in a thickness direction. A sensor head includes this excitation core and a magnetism collecting body. This magnetism collecting body includes strip-shaped first magnetism collector and second magnetism collector. Both ends of the first magnetism collector and both ends of the second magnetism collector are in contact with one another to form the annular magnetism collecting body. This magnetism collecting body is disposed at an inside or an outside of the reinforcing body.
