Problems solved by technology

[0003] When the existing Hall current sensor performs detection work, the user needs to pass the cable through the hole of the Hall current sensor, but the cable is easy to deviate from the position of the central axis of the Hall current sensor, thereby affecting the position of the Hall current sensor. The measurement e

Abstract

The invention relates to a Hall current sensor with heat dissipation and fixing functions. The sensor includes a main body, a pedestal, a fixing mechanism and a heat dissipation mechanism. The fixingmechanism comprises a support, two first springs and two fixing components. Each fixing component includes a connecting plate, a connecting rod, a fixing plate and several connecting units. The heat dissipation mechanism includes a draught fan and two heat dissipation components. Each heat dissipation component includes a ventilation pipe, a filter screen, a limiting ring and two limiting components. Each limiting component includes a pressing plate, a pressing rod, a limiting rod, a limiting plate and a second spring. By using the Hall current sensor with the heat dissipation and fixing functions, the function of fixing a cable is achieved through the fixing mechanism, the cable and the main body are coaxially arranged, measurement precision is improved, the heat dissipation function is achieved through the heat dissipation mechanism, and a situation that normal work of the main body is affected due to a fact that a temperature in the main body is too high is avoided.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a Hall current sensor with heat dissipation and fixing functions. 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 pot...
