Sensor assembly for a current sensor, current sensor with such a sensor assembly, holder for such a current sensor, and method for assembling a current sensor

摘要

A sensor assembly for a current sensor is provided having a Hall element and a holder for the Hall element, the holder being rigid and including a retainer for the Hall element, in which it is received with small tolerances, and two contact surfaces for a magnetic core. A current sensor having such a sensor assembly and a magnetic core is also provided which has at least one gap in which the holder is arranged, so that the Hall element extends perpendicularly to a direction in which magnetic field lines pass through the gap. A holder for such a current sensor is also provided wherein it consists of a mechanically hard, non-magnetic material, preferably hard plastics or acrylic glass. Lastly, a method of assembling a current sensor is also provided.
