Current sensor |
摘要 |
A current sensor includes: a core formed by U-shaped flat plates made of a magnetic body and stacked together; a flat plate-like conductor which is inserted on an interior side of a U-groove of the core and through which a current to be measured flows; a detection element which is arranged on the side of an opening of the U-groove in such a way that a detecting direction extends in a spacing direction of the opening, and which detects a strength of a magnetic field; a housing which supports the core, the conductor and the detection element; and a pair of spacing direction supporting portions which are provided at positions along the spacing direction on both sides of the detection element, in an opening-side end of the core, and which abut on the housing. |

1. A current sensor comprising:
a core formed by U-shaped flat plates made of a magnetic body and stacked together; a flat plate-like conductor which is inserted on an interior side of a U-groove of the core and through which a current to be measured flows; a detection element which is arranged on the side of an opening of the U-groove in such a way that a detecting direction extends in a spacing direction of the opening, and which detects a strength of a magnetic field; a housing which supports the core, the conductor and the detection element; and a pair of spacing direction supporting portions which are provided at positions along the spacing direction on both sides of the detection element, in an opening-side end of the core, and which abut on the housing; wherein in the core, a first flat plate having a U-shaped portion and a protruding portion protruding along the spacing direction from a lateral surface of the U-shaped portion, and a second flat plate having a U-shaped portion with the same shape as the U-shaped portion of the first flat plate are stacked in such a way that the first flat plate is arranged toward a center in a stacking direction, with the U-shaped portions coinciding with each other, and a portion of the housing that enters from the side of the opening abuts on a bottom part of the U-groove, and an opening direction supporting portion on which the housing abuts from a side opposite to the side of the opening and which is thus supported along an opening direction of the U-groove is provided at a shoulder portion which is provided on the protruding portion at a position on the interior side of the opening and coincides with the bottom part along the spacing direction, and a distal end on the side of the opening of the core is spaced away from the housing. |
