Abstract
The utility model relates to the sensor technical field and especially relates to a current sensor comprising an annular magnetic core portion and a magnetic detecting portion. The magnetic core portion comprises a closed magnetic circuit locally comprising a gap and a magnet used for generating magnetic flux of a magnetic field around a detected conductor with flowing current. The magnetic core portion comprises multiple pairs of step portions which are arranged on a pair of end faces forming the gap and which declines along the direction away from the conductor. The magnetic core portion is wrapped in a housing coaxially connected with a cable joint. By mutually cooperative connection and impacts between the annular magnetic core portion and the magnetic detecting portion, the current sensor is provided with characteristics of uniformly-distributed integral magnetic force, miniaturization, low cost, and easy installation. By the magnetic core portion wrapped in the housing and the housing coaxially connected with the cable joint, current information can be accurately detected by the magnetic force under the condition of uniformly-distributed magnetic force.
