Device for detecting current flowing in an electric wire
First Claim
1. A current detecting device for detecting current flowing in a first electric wire arranged close to a second electric wire having a portion extending in a predetermined direction, said second electric wire extending between a device of an automotive vehicle and a battery of said automotive vehicle, said first electric wire extending from a portion of said second electric wire located in a fuse unit to at least one electrical load, comprising:
- a portion of said first electric wire extending at right angles to said portion of said second electric wire;
a magnetic core arranged around said portion of said first electric wire, said magnetic core having an axis thereof extending at right angles to said portion of said second electric wire; and
magnetic-to-electric transducer means associated with said magnetic core for generating an electric signal indicative of the intensity of a magnetic field generated around said portion of said first electric wire by current flowing in said first electric wire.
