BUS BAR MODULE EQUIPPED WITH CURRENT SENSORS

摘要

A bus bar module equipped with current sensors is provided. The module includes a plurality of bus bars, a current sensor, and shield plates. The current sensor is formed of a magneto-resistive element. The plurality of bus bars are arrayed along a width direction (X direction) of the bus bars that is at right angles to both the thickness direction (Z direction) and the extension direction (Y direction) of the bus bars. The current sensor is arranged being spaced apart from the bus bars, while being adjacent to the bus bars in the Z direction. The bus bars and the current sensor are covered from both sides in the Z direction, by the shield plates.

1. A current sensor-equipped bus bar module wherein that the module comprises:
a plurality of bus bars in which currents flow; a current sensor which measures a value of current in at least a part of the plurality of bus bars; and a shield plate which shields magnetic fields generated around the bus bars, wherein: the current sensor comprises a magneto-resistive element, and measures the value of current in a bus bar by detecting a strength of the magnetic field which is generated around the bus bar by the flow of the current in the bus bars: the plurality of bus bars are arrayed along a width direction that is at right angles to an extension direction of the bus bars and to a thickness direction of the bus bars; the current sensor is disposed adjacent to the bus bars in the thickness direction, and spaced apart from the bus bars; and the current sensor and the bus bars are covered from both sides, in the thickness direction, by shield plate.
