  Conventionally, many direct current sensors having a structure in which a ring-shaped gap iron core and a Hall element are combined have been commercialized. In particular, a structure in which a ring-shaped iron core is divided and sandwiched between existing wires is used as a clamp-type current sensor for on-site current monitoring.

  By the way, if the current sensor is not arranged at the center position of the annular magnetic body, the magnetic flux generated in the magnetic body may not be uniform and current measurement errors may occur. In use, if the wiring can be positioned at the center of the hole of the magnetic body of the current sensor, more accurate current measurement can be performed.

  For this reason, the current sensor described in Patent Document 1 has a case having a U-shaped guide groove for guiding the wiring and a U in order to hold the wiring inserted in the guide groove of the case. Magnetic field generated from a holder that has a protruding part that fits into the letter-shaped guide groove and that can be attached to and detached from the case, and wiring that is placed at a position facing the center of the wiring at equal intervals in the case And a detection circuit that converts a magnetic field acting on the magnetic head into a voltage, ensuring electrical insulation between the wiring and the detection head, and of course not cutting the existing wiring. It is characterized by high sensitivity and good linearity without deterioration.
