Abstract
The utility model discloses a kind of leakage-proof type foamed aluminium electromagnetic casing screen structure, it is characterized in that 45 ° of oblique angle overlap joints of sheet edge, form vertical stratification；The wedge-shaped foamed aluminium feet of increase inside oblique angle, thoroughly to shield electromagnetic path, as shown in the figure.Corner fixed form fixes (nut insertion foamed aluminium) or other modes for riveting, bolt behind gluing, peripheral iron clad skin corner, wherein, if there is such as figure such as rivet, bolt for penetrating foamed aluminium material, the side in case is covered by foamed aluminium feet.Body structure of the present utility model is simple, practical, and good airproof performance can effectively shield electromagnetic path.
Description
Technical field
The utility model is related to electromagnetic shielding box technical field, and in particular to a kind of leakage-proof type foamed aluminium electromagnetic shielding box
Body structure.
Background technology
Electronics, communication, computer and electrical equipment etc. largely enter today's society and family, significantly improve people's
Material, culture and living standard, but at the same time also bring the problem of some are new.Electronic equipment constructs special, working method
It is special, as long as in running order, the electromagnetic wave that just inevitably outside transmitted spectrum composition enriches, what these frequency spectrums enriched
Electromagnetic wave brings substantial amounts of negative effect to information security not only to people, machine, environment.For example electromagnetic interference is brought
Harm of the information security threats and electromagnetic pollution that equipment work is disorderly, electromagnetic exposure is brought to health.
Foam metal is a kind of Combined Electromagnetic Shielding Materials risen in the last few years, compared with traditional web material, and it is shielded
Efficiency is high, can meet the shielding needs of preferable sensitive instrument and equipment；Compared with sheet material, its light weight, weatherability are strong, be easy to peace
Dress, is the superior material for building electronics room.The foam metal material worked out at present has foamed aluminium and its alloy, foam
Nickel, titanium foam etc., wherein it is foamed aluminium to study the most ripe, and have shown before wide application in actual life
Scape.
Foamed aluminium be in pure aluminum or aluminum alloy add additive after, formed by foam process, at the same have concurrently metal and
Bubble feature.Its density is small, high-selenium corn impact capacity is strong, electromagnetic wave shielding is high, weatherability is strong, have filter capacity, easy processing, easily
Install, forming accuracy is high, external coating can be carried out, in addition, the characteristics of also having recyclable concurrently.
Foamed aluminium electromagnetic casing screen structure is for shielding electromagnetic interference, the electricity that electromagnetic equipment is brought in the process of running
The problems such as electromagnetic pollution, by the design of specific structure, it can effectively shield electromagnetic path.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, practicality, good airproof performance anti-leak
Type foamed aluminium electromagnetic casing screen structure.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of leakage-proof type foamed aluminium electromagnetic casing screen structure, the casing is combined by bottom plate and side plate, its midsole
Plate and side plate are foam aluminium plate, and the bottom plate and side board edge are overlapped with 45 ° of oblique angles, vertical stratification are formed, in oblique angle
The wedge-shaped foamed aluminium feet of portion's increase, thoroughly to shield electromagnetic path.
The corner fixed form of the bottom plate and side plate fixes (nut for riveting, bolt behind gluing, peripheral iron clad skin corner
Embedded foamed aluminium) or other modes, wherein, if there is rivet, bolt for penetrating foamed aluminium material etc., the side in case
Covered by foamed aluminium feet；
To avoid the electromagnetic exposure in body structure, foamed aluminium is added in body structure and the corner of body structure is set
Count oblique angle at 45 ° and be overlapped to form vertical stratification.
Steel on the outside of sheet material after one layer of 5mm of parcel.
Board dimension about 40cm × 40cm × 2cm.
The beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design, is being run in electronic equipment
Cheng Zhong, this body structure can effectively shield electromagnetic path, so as to avoid the information security threats, electricity that electromagnetic exposure brings
The equipment work disorder that magnetic disturbance is brought and the harm that electromagnetic pollution is caused to health.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, a kind of leakage-proof type foamed aluminium electromagnetic casing screen structure, the casing is combined by bottom plate 1 and side plate 2
Form, wherein bottom plate 1 and side plate 2 are foam aluminium plate, board dimension about 40cm × 40cm × 2cm.Bottom plate 1 and the side of side plate 2
Edge is overlapped with 45 ° of oblique angles, forms vertical stratification, is increased wedge-shaped foamed aluminium feet 3 inside oblique angle, is led to thoroughly shielding electromagnetism
Road.The corner fixed form of bottom plate 1 and side plate 2 fixes (nut insertion bubble for riveting, bolt behind gluing, peripheral iron clad skin corner
Foam aluminium) or other modes, wherein, if there is rivet, bolt for penetrating foamed aluminium material etc., the side in case is foam
Aluminium feet 3 is covered；To avoid the electromagnetic exposure in body structure, foamed aluminium is added in body structure and by body structure
Design oblique angle at 45 ° and be overlapped to form the steel wrapped up on the outside of vertical stratification, sheet material after one layer of 5mm in corner.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
