Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, a group of Hall sensors are required for phase positioning in the hub motors used in existing small vehicles such as electric vehicles. Vibration and bumps can easily cause the Hall sensor to loosen and fall off, which affects the position detection accuracy of the Hall sensor. A Hall sensor proposed by the present invention

Embodiment approach

[0026]As an embodiment of the present invention, the end of the sleeve 4 away from the body 1 is provided with an annular cavity 6, and a tightening ring 7 is arranged in the annular cavity 6, and a group of pull ropes 8 are evenly distributed on the circumference of the tightening ring 7, The drawstring 8 is fixedly connected to the fixing ring 5 on the side close to the body 1; the drawstring 8 runs through the fixation ring 5 except on the side close to the body 1, and is slidably connected with it; when the pin 2 is bent, the drawstring is driven 8 Tensioning tightens the ring 7 to increase the sealing of the sleeve 4 and further reduce the water ingress corrosion of the pin 2; when the pin 2 bends and drives the sleeve 4 to bend, the part of the sleeve 4 located outside the bend is stretched Long, the sleeve 4 is squeezed and shortened at the inner part of the bend, because the stay rope 8 is fixedly connected with the fixing ring 5 near the body 1 side, so that the stay r...

Abstract

The invention belongs to the technical field of sensors, specifically a Hall sensor, including a main body; a group of pins are provided on one side of the main body, and a protective cover is provided on the side of the main body close to the pins, and the protective cover is sealed and connected with the main body to protect the sensor. The corresponding position of the sleeve and the pin is provided with an insulating sleeve; the invention aligns the pin and inserts it into the sleeve until the body is embedded in the protective sleeve and is sealed with the protective sleeve; the contact short circuit after the pin is bent is avoided by the insulating sleeve , to ensure the normal operation of the body, and because the sleeve has a certain degree of elasticity, it hinders excessive bending of the pins, reduces cracking or even breaking at the root of the pins after excessive bending of the pins, and ensures the normal working performance of the body.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a Hall sensor. Background technique [0002] The Hall sensor is a magnetic field sensor made according to the Hall effect. Hall effect is a kind of magnetoelectric effect. This phenomenon was discovered by Hall (A.H.Hall, 1855-1938) in 1879 when he was studying the conductive mechanism of metals. Later, it was found that semiconductors and conductive fluids also have this effect, and the Hall effect of semiconductors is much stronger than that of metals. Various Hall elements made of this phenomenon are widely used in industrial automation technology, detection technology and information processing, etc. aspect. The Hall effect is a basic method for studying the properties of semiconductor materials. The Hall coefficient measured by the Hall effect experiment can determine important parameters such as the conductivity type, carrier concentration, and carrier mobility of semico...
