Abstract
The utility model relates to a cabinet for placing electronic equipment, in particular to a nine-edge bending section cabinet with the function of electromagnetic shielding. The cabinet is formed by the split joint of a frame, a front door, a back door and a side plate. The cabinet is characterized in that the frame is a conductor which is welded by a standard nine-edge bending section, the standard nine-edge bending section is formed by bending an aluminum-covered zinc plate, the seal of the section is sewn by means of spot welding, and the front door, the back door and the side plate are formed by bending the aluminum-covered zinc plate. The cabinet has the advantages of keeping the structural features and the carrying capacity of the existing nine-edge bending cabinet, having good magnetic permeability, electric conductivity and corrosion resistance, and leading the shielding performance of the cabinet to meet the requirement of the electromagnetic compatibility of equipment.
Description
Technical field
The utility model relates to the rack that is used to place electronic equipment, is specifically related to a kind of nine Edge Bend section bar racks with electro-magnetic screen function.
Background technology
Along with the high speed development of electronic technology and the extensive use on electronic product thereof, cause electromagnetic environment constantly to tend to worsen, and this electromagnetic pollution has been not limited only to the problem between equipment and the equipment, also to further relate to human living environment itself.For the equipment fault problem that reduces or avoid causing owing to electromagnetic interference, electromagnetic shielding (EMC) is must solve important step in the electronic device design process, and the electromagnetic shielding of rack structure (EMC) design is to realize one of important means of product electromagnetic shielding (EMC).
Electromagnetic-field-shielded principle mainly is based on electromagnetic wave and passes the mechanism that the metallic shield body produces wave reflection and ripple absorption.Electromagnetic wave transmits in metal material and can puberty decay, and attenuation degree depends on permeability, the conductance of material.For electric field, the material decay that conductance is high is big; For magnetic field, the material decay that permeability is high is big.Obviously, make the rack structural design satisfy the electromagnetic shielding requirement, material selection, version, slit and perforate are the keys of problem.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of nine Edge Bend section bar racks with electro-magnetic screen function are provided, nine fold-type materials of the Qianmen of this rack, side plate and formation framework form by covering the bending of aluminium zine plate, have good permeability, conductance and corrosion resistance.
The utility model purpose realizes being finished by following technical scheme:
A kind of nine Edge Bend section bar racks with electro-magnetic screen function, described rack includes framework, Qianmen, back door and side plate and is spliced to form, it is characterized in that: described framework is a conductor that is welded to form by standard nine Edge Bend section bars, described standard nine Edge Bend section bars adopt and cover aluminium zine plate bending and molding, its section bar sealing part adopts spot welding to sew up, and described Qianmen, back door and side plate form by covering the bending of aluminium zine plate.
The surface of described Qianmen, back door and side plate has the powder sprayed coating.
Described Qianmen, back door connect by 4 hinging manners with described framework.
4 locks are installed on described Qianmen, the back door, when the Qianmen is closed, can realize 4 lockings up and down.
Offer the identical regular hexagon louvre of a plurality of sizes on the described side plate.
Described louvre evenly, be staggered.
The surface of described framework weld has the cold galvanizing processing layer.
The utility model has the advantages that: kept the design feature and the bearing capacity of former nine Edge Bend racks, had good permeability, conductance and corrosion resistance again, the rack shielding properties satisfies the electromagnetic compatibility requirement of equipment.
