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, and particularly relates to a Hall sensor which comprises a body; one side of the body is provided with a group of pins; one side, close to thepins, of the body is sleeved with a protective sleeve, the protective sleeve is hermetically connected with the body, and the protective sleeve is provided with an insulating sleeve at a position corresponding to the pins; the pins are aligned and inserted into the sleeve until the body is embedded into the protective sleeve and is in sealed connection with the protective sleeve; contact short circuit after the pins are bent is avoided through the insulating sleeves, normal work of the body is guaranteed, meanwhile, due to the fact that the sleeves have certain elasticity, excessive bending of the pins is hindered, cracking and even breaking of the pins at the roots of the pins after excessive bending are reduced, and normal work performance of the body is guaranteed.

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...
