Abstract
The utility model relates to magnetic steel, in particular to NdFeB (neodymium iron boron) magnetic steel used for automobile sensors. The NdFeB magnetic steel comprises a magnetic steel body, four corners of the magnetic steel body are respectively provided with assembling notches, the width between the transverse assembling notches ranges from 7.8mm to 8.2mm, the width between the longitudinal assembling notches ranges from 5.8mm to 6.2mm, the magnetic steel body is made of NdFeB magnetic steel, and a nickel-plated layer covers the surface of the magnetic steel body. The NdFeB magnetic steel used for the automobile sensors is compact in structure, product performance is improved, and service life is prolonged.
Description
Technical field
The utility model is a kind of magnet steel, and particularly a kind of Nd-Fe-B magnet steel for automobile sensor, is applied to automobile sensor.
Background technology
Magnet steel of the prior art, complex structure, and also fixed form is insecure, and result of use is not good, causes reduce its useful life.
Chinese patent 201020150678.5, discloses a kind of magnet, particularly a kind of samarium cobalt magnet with cambered surface that is mainly used in microwave communication technology, audio-visual technology, electrical engineering etc.Comprise magnet, described magnet pack is drawn together contour body and square body, and described contour body and square body are integrated, in described magnet, are provided with intermediate layer, and intermediate layer is coated with nickel coating.This structure relative complex, useful life is relatively low.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, compact conformation, and lifting assembly precision greatly promotes the Nd-Fe-B magnet steel for automobile sensor of transducer serviceability simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of Nd-Fe-B magnet steel for automobile sensor, comprise magnet steel, four jiaos of described magnet steel are respectively equipped with assembling breach, laterally the width between assembling breach is 7.8～8.2mm, longitudinally the width between assembling breach is 5.8～6.2mm, the material of described magnet steel is Nd-Fe-B magnet steel, and the surface of described magnet steel is covered with nickel coating.
As preferably, described magnet steel is cuboid, and the length of described magnet steel is 11.8～12.2mm, and the width of described magnet steel is 9.8～10.2mm, and the thickness of described magnet steel is 3.8～4.2mm.
As preferably, between described assembling breach and magnet steel, by the transition of chamfering phase, in described assembling breach, be provided with circular arc knuckle.
In magnet steel, be provided with displacement transducer, in the time that the displacement of magnet steel generation exceedes certain amount, displacement transducer gives the alarm to control centre.
Therefore, the Nd-Fe-B magnet steel for automobile sensor that the utility model provides, compact conformation, improving product performance, increases the service life.
