Hall current sensor with shock-absorbing function convenient for installation

Abstract

The invention relates to a Hall current sensor with a shock-absorbing function convenient for installation. The Hall current sensor with the shock-absorbing function convenient for installation comprises a mounting base, a main body, a support plate, a shock-absorbing mechanism, two fixing mechanisms and a plurality of pins; each fixing mechanism comprises a fixing component and a limiting component; the fixing component comprises a suction cup, a fixing box, a moving plate, a driving component and two first springs; the shock-absorbing mechanism comprises an air bag and two shock-absorbing components; and each shock-absorbing component comprises a connection box, a connecting tube, a piston and a second spring. According to the Hall current sensor with the shock-absorbing function convenient for installation, the function of installing the main body is realized through the fixing mechanisms, therefore, the convenience of installing the Hall current sensor is improved; and the functionof shock-absorbing to the main body is realized through the shock-absorbing mechanism.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a conveniently installed Hall current sensor with a damping function. Background technique [0002] The Hall current sensor is based on the magnetic balance Hall principle. According to the Hall effect principle, the current Ic is passed through the control current terminal of the Hall element, and a magnetic field with a magnetic induction intensity of B is applied in the normal direction of the Hall element plane. Then in the direction perpendicular to the current and the magnetic field (that is, between the Hall output terminals), a potential VH will be generated, which is called the Hall potential, and its magnitude is proportional to the control current I. and the product of magnetic induction B. That is, in the formula: K is the Hall coefficient, which is determined by the material of the Hall element; I. is the control current; B is the magnetic induction intensity; VH is the Hall...

AI Technical Summary

Problems solved by technology

[0003] Existing Hall current sensors are generally fixed by bolts, which require drilling first, which makes the installation process more cumbersome and reduces the convenience of installation. Not only that, but the existing Hall current sensors generally do not have shock absorbing devices , if the vibration occurs and the vibration is too large, it is easy to affect the normal operation of the electronic components inside the Hall current sensor, reducing the safety of the Hall current sensor
