The invention discloses a
magnetic circuit mounting structure for a detachable open-loop-type Hall
current sensor, and belongs to the technical field of
magnetic circuit mounting. The magnetic circuitmounting structure comprises a shell, and further comprises a PCB, a
magnetic core and a shielding frame which are mounted in the shell; an upper body of the shell is provided with a
magnetic core mounting area, a baffle and an upper body elastic buckle structure; a
lower body of the shell is provided with a
magnetic core mounting area, two
Hall element mounting areas and a PCB mounting area, wherein the magnetic core mounting area is provided with a
lower body elastic buckle structure; the
Hall element mounting areas are provided with PCB mounting table columns,
Hall element inserting grooves and magnetic core baffles; the PCB mounting area is provided with mounting columns and buckles; and the shielding frame is provided with elastic sheets and grounding pins, and the grounding pins penetrate through grounding
welding holes in the PCB to be welded and grounded. According to the
magnetic circuit mounting structure, during mounting, the magnetic core is flatly pushed to the bottom through the magnetic core baffles and the elastic buckle structures, a ground wire is not welded to the magnetic core, the magnetic core is good in air
gap width consistency and temperature stability, Hall elements do not need to be wrapped with insulation belts, and the PCB is mounted and not skewed.
