The electromagnetic screen is mainly composed of a pull type storage box, a solenoid, an electromagnetic shielding cover, a front fixed plate, a rear fixed plate and a base plate. The electromagnetic screen possesses the characteristics of simple structure, convenient assembly and disassembly and good electromagnetic shielding effect, and is suitable for the electromagnetic shielding of the solenoid of a magnetic storage medium degausser.
Description
Technical field
The utility model discloses a kind of electromagnetic screen for degausser, belong to electromangnetic spectrum field, for preventing the electromagnetic leakage of magnetic-based storage media degausser.
Technical background
Degausser is a kind of equipment that can eliminate fast all storage information above magnetic-based storage media such as hard disk, floppy disk, tape and magnetic card.While adopting electromagnetic field mode to carry out demagnetization to magnetic-based storage media, in solenoid, can produce moment highfield, other electric device to degausser of highfield of described moment and extraneous people know from experience and have a huge impact.At present, in the mode that mainly adopts other electric device that shields degausser aspect the protection of highfield, but not shielding produces the electromagnetic coil structure of highfield.This kind of protection method is unsatisfactory to the shield effectiveness of described components and parts, often there will be the phenomenon of electronic component failure, what is more important, and this kind of protection method do not considered radiation and the injury of human body to external world of moment highfield.
Summary of the invention
It is a kind of for preventing the electromagnetic screen of degausser electromagnetic leakage that the utility model main purpose is exactly design.This apparatus structure is simple, easy installation and removal, and effectiveness is good.
The utility model solves its technical problem and realizes by the following technical solutions.
A kind of electromagnetic screen for degausser the utility model proposes, is made up of drawing and pulling type storage box, solenoid, electro-magnetic shielding cover, front shoe, rear fixed plate and base plate.Front panel is welded on base plate, and solenoid is arranged on front shoe and rear fixed plate, and rear fixed plate screw thread is fixed on base plate, and position is fine-tuning; One end and the front shoe of electro-magnetic shielding cover are combined closely, and underrun is threaded and is fixed on base plate; Drawing and pulling type storage box can free in and out solenoid by manual pull mode.
In such scheme, described drawing and pulling type storage box forms by storing lid, storage box body, square magnet and zigzag boss, and storage covers two square magnets and a zigzag boss are installed; On described front shoe, be welded with zigzag groove.
In such scheme, on the contact-making surface of described front shoe, rear fixed plate, base plate, solenoid and electro-magnetic shielding cover, install respectively conductive rubber pad additional, electro-magnetic shielding cover adopts the good brass material of electric conductivity, and solenoid, front shoe and rear fixed plate are covered wherein completely.
Can find out its beneficial effect by technical scheme described in the utility model:
1. the sealing of drawing and pulling type storage box described in the utility model and front shoe adopts zigzag emboss pit engage and the mode of magnet, simple in structure, good sealing effect and applied widely, except being applied to the electromagnetic leakage that prevents degausser, can also being applied to general rectangular opening the occasion with seal request.
2. electro-magnetic shielding cover described in the utility model adopts brass material, the mode of pasting conductive rubber pad by bottom surface is fixed on base plate, solenoid, front shoe and rear fixed plate are covered wherein completely, form good shielded enclosure, increased effectiveness.
3. the utility model, take armoured magnetic field source as starting point, adopts various electromangnetic spectrums, and structural design is simple, and shield effectiveness is good, better reaches the object of human body and degausser electronic devices and components protection to external world.
