Abstract
The utility model discloses a kind of board-like magnetic field shielding device and comprise board-like radome, the distance member that described radome comprises multilayer laminated thin plate and is arranged between adjacent thin plate, described thin plate adopts permeability magnetic material to make, and described distance member adopts non-magnetic material to make; Described radome has at least a side upwards to bend, and radome is provided with trough.The utility model is rational in infrastructure, is applicable to multiple different installation requirements, and can shield electromagnetic interference effectively.
Description
Technical field
The utility model relates to a kind of magnetic shielding device, particularly relates to a kind of board-like electromagnetic screen.
Background technology
Electromagnetic interference is very large on the impact of sensing instrument equipment and electronic component, and it normally works the environmental magnetic field around equipment must to be shielded in certain scope guarantee.At present, for the anti-strong magnetic requirement on intelligent electric energy meter, nearly all adopting the protection of device level, as carried out independent iron-clad lock shield to on-load switch, independent iron-clad lock shield being carried out to instrument transformer.It is comparatively large that this mode increases cost, technique inconvenience, and band metal-back device outside magnetic field effect lower stress is yielding.Especially, in recent years, also occurred a kind of polyhedron electromagnetic screen, not only production cost is high, and structure is comparatively complicated, can not change to be applicable to multiple different installation requirements.
Utility model content
Goal of the invention of the present utility model is the limitation solving above-mentioned existing a kind of board-like electromagnetic screen, provides a kind of rational in infrastructure, is applicable to multiple different installation requirements, and can the board-like electromagnetic screen of shield electromagnetic interference effectively.
The utility model comprises board-like radome, the distance member that described radome comprises multilayer laminated thin plate and is arranged between adjacent thin plate, and described thin plate adopts permeability magnetic material to make, and described distance member adopts non-magnetic material to make; Described radome has at least a side upwards to bend, and radome is provided with trough.
After adopting above structure, the utility model compared with prior art, has the following advantages:
The utility model comprises board-like radome, described radome has at least a side upwards to bend, the face that can freely shield on demand and the shape area of installation place carry out flexible bending and arrangement, more effectively utilize installing space, and bending arrangement in each side can absorb magnetic force.Adopt the thin plate made of multilayer permeability magnetic material interval, substitute one block of traditional slab, the permeability magnetic material that Spaced the is arranged thin plate shielding of making is diamagnetic can reach better effect.Adopt distance member to be arranged in multilayer permeability magnetic material, the thin plate of radome is combined into one.The utility model is rational in infrastructure, is applicable to multiple different installation requirements, and can the board-like electromagnetic screen of shield electromagnetic interference effectively.
As preferably, the permeability magnetic material that described thin plate adopts is electrical pure iron thin plate.Electrical pure iron is Armco iron again, is the high-quality steel of a kind of iron-holder more than 99.5%, is a kind of low-carbon and low-sulphur low phosphor iron.Electrical pure iron irony ground is soft, and toughness is large, has good electromagnetic performance.
As preferably, described distance member comprises copper post or aluminium post, described copper post or the axis of aluminium post mutually vertical with described thin plate.Copper and aluminium are non-magnet materials, and sound construction is cheap, copper post and aluminium post can be adopted to be combined into one by the thin plate of multilayer magnetic conduction at this.
As preferably, the non-magnetic material that described distance member adopts is plastics.Plastics low cost of manufacture, resistance to corrosion is strong, is good non-magnet material, is easily moulded and make difformity.
As improvement, the one side of described radome is provided with clasp.It is more convenient that described clasp can make the utility model install, and button can be adopted firmly to snap in panel.
As improvement, the side of the upwards bending of described radome is provided with holddown groove.Can be used for fixedly mounting the assembly into radome.
As improvement, described trough is the elasticity draw-in groove of strip.Wire on the equipment that described elasticity draw-in groove is installed in this screening arrangement passes through.
The utility model adopts radome to carry out concentrating shielding, and conventional components and parts still used by components and parts device, and portable construction is reasonable, and make simple, cost is low; Easy installation, dismounting, convenient and reliable, not by Magnetic force tracting under outside magnetic field.
