Abstract
The utility model relates to the technical field of sensors, in particular to a current sensor. The current sensor comprises a ring-shaped magnetic core part and a magnetic detection part, wherein the magnetic core part comprises a closed magnetic circuit partially comprising a gap, and a magnet used for converging magnetic flux of magnetic fields produced around a conductor through which a current to be detected flows; multiple pairs of step parts descending in a direction deviated from the conductor are arranged on a pair of end surfaces of the magnetic core part, which is provided with the gap; and a shell is coated on the magnetic core part and is coaxially connected with a cable joint. The current sensor has the advantages that through mutually-matched connection and action of the ring-shaped magnetic core part and the magnetic detection part, magnetic force of the whole sensor is evenly distributed, the miniaturization is realized, the cost is low and the mounting is convenient; and the shell is coated on the magnetic core part and is coaxially connected with the cable joint, so under the circumstance that the magnetic force is evenly distributed, current information can be accurately detected through the magnetic force.
