A Hall plate installation structure based on zero-flux Hall high-current sensor

Abstract

The invention discloses a Hall sheet mounting structure based on zero magnetic flux Hall heavy current sensor, comprising a mounting body and an attachment. The attachment comprises a Hall sheet fixedplate and a Hall sheet installing plate. The mounting body is vertically provided with a magnetic core fixed slot, whose width is equal to that of the magnetic core. The mounting body is transverselyprovided with a Hall sheet installing plate standing groove. The invention is advantageous in that through controlling the thickness of the Hall sheet installing plate and the position of a U-shapedgroove in the Hall sheet installing plate, the problem that the air gap and magnetic flux leakage between magnetic cores are large can be resolved, and the Hall sheet can be guaranteed to be placed inthe central position of the magnetic field; through the cooperation of the mounting body, the Hall sheet installing plate, and the Hall sheet fixed plate, the Hall sheet can be prevented from being extruded, and stability and maneuverability are good; all the structures are placed at the same side of the housing of the sensor, and with the mounting structure of the Hall sheet, the debugging, maintenance and replacing of the Hall sheet of the sensor can be more convenient.

Description

technical field [0001] The invention relates to the technical field of Hall current sensors, in particular to a Hall plate installation structure based on a zero-flux Hall high-current sensor. Background technique [0002] The zero-flux Hall high-current sensor is used to collect high-current signals. Can its structural design function solve the air gap between magnetic cores and large magnetic flux leakage, and ensure that the Hall plate is in the center of the magnetic field, free from extrusion, stable, Operability and other issues will have a crucial impact on its performance. At present, there are many installation structures of the Hall plate of the known zero-flux Hall high-current sensor, but the air gap between the magnetic cores and the magnetic flux leakage are large, and the Hall plate is difficult to be centered, easy to be squeezed, and the installation is unstable. Poor operability and the like cannot meet the demand. Contents of the invention [0003] The...
