Abstract
The utility model relates to magnet steel, in particular to circular samarium cobalt magnet steel provided with a trumpet-shaped opening. The circular samarium cobalt magnet steel is applied to electronic elements. The circular samarium cobalt magnet steel comprises a magnet steel body. An isosceles trapezoid hole and a column hole are formed in the middle of the magnet steel body. The column hole is formed on the lower portion of the isosceles trapezoid hole and is communicated with the isosceles trapezoid hole. The open angle of the isosceles trapezoid hole is 90 +/-1 degrees. The magnet steel body is made of samarium cobalt magnet steel and is circular. The circular samarium cobalt magnet steel provided with the trumpet-shaped opening is compact in structure, improves product performance, and prolongs service life.
Description
Technical field
The utility model is a kind of magnet steel, and particularly a kind of circular SmCo magnet steel with horn-like opening is applied to electronic device.
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, is provided with the intermediate layer in the described magnet, and the intermediate layer is coated with nickel coating.This structure relative complex, useful life is relatively low.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and compact conformation promotes the circular SmCo magnet steel with horn-like opening in useful life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of circular SmCo magnet steel with horn-like opening, comprise magnet steel, the interposition of described magnet steel is provided with isosceles trapezoid hole and post hole, the bottom in described isosceles trapezoid hole is provided with and is attached thereto logical post hole, the opening angle in described isosceles trapezoid hole is 90 degree ± 1 degree, the material of described magnet steel is the SmCo magnet steel, and described magnet steel is circular.
As preferably, the diameter on top, described isosceles trapezoid hole is 10.2mm, and the diameter in described post hole is 4.5mm, the equal diameters of the diameter in described post hole and bottom, isosceles trapezoid hole, the thickness of described magnet steel is 4.2mm, and the diameter of described magnet steel is 22.5mm.
As preferably, the density of described magnet steel is 8.2～8.5g/cm
3, the outer knuckle of described magnet steel is that radius is the chamfering of 0.2mm.
Therefore, the circular SmCo magnet steel with horn-like opening that the utility model provides, compact conformation, the improving product performance increases the service life.
