Hall current sensor with strong anti-jamming capability

Abstract

The invention belongs to the technical field of sensors and discloses a Hall current sensor with a strong anti-jamming capability. The Hall current sensor comprises a U-shaped silicon steel sheet anda shell; an opening in the top of the shell is of a hollow structure; a supporting plate is movably connected into the shell; the supporting plate is connected with the shell through a buffering mechanism; the upper surface of the supporting plate is fixedly connected with a supporting rod which is close to one end of the supporting plate; one end of the supporting rod is rotationally connected with a PCB through a rotation shaft; the PCB is connected with the supporting plated through a calibration mechanism; the upper surface of the PCB is fixedly connected with two symmetric mounting blocks; grooves are formed in the upper surfaces of the mounting blocks respectively; positions at two ends of the bottom end of the U-shaped silicon steel sheet, which are corresponding to the grooves, arefixedly connected with protruding blocks matched with the grooves; and one side of each protruding block, which is far away from the U-shaped silicon steel sheet, abuts against the groove bottom of the corresponding groove. The installation and current calibration of the Hall current sensor with the strong anti-jamming capability are facilitated; and the Hall current sensor has high impact resistance.
