Description
Technical field
The utility model belongs to electromangnetic spectrum field, particularly relates to a kind of conductive plastics computer shield shell.
Background technology
The accumulation of static charge and release, electromagnetic interference (EMI) and radio wave interference are two hang-ups that electron trade faces.The accumulation of static charge and release can make various exact instrument, precision electronic element is breakdown and scrap.Electromagnetic interference (EMI) and radio interference directly or indirectly can cause electronic devices and components misoperation or system down.Therefore, in the relating to of the precision components such as electronic equipment, integrated circuit, produce, accumulating, antistatic and electromagnetic screen problem must be considered in operational process.Electromagnetic shielding material mainly contains metal, common engineering plastics and conductive plastics.Metal has excellent electric conductivity, is traditional antistatic, electromagnetic shielding material, but metal material exists that density is large, price, difficult processing, perishable, antistatic and shielding properties are difficult to the shortcomings such as conciliation.Although common engineering plastics have, quality is light, price is low, the feature of corrosion-resistant, easy-formation, but be generally insulator, easy accumulate static charge, and to electromagnetic field almost without any shielding action, especially to below 1GHz and low-frequency electromagnetic wave be almost completely " through ", therefore cannot be applied to antistatic, electromagnetic screen field.Conductive plastics has the advantage of common plastics, has the conductive characteristic of metalloid simultaneously, is a kind of desirable antistatic, electromagnetic shielding material.The structure of current electromagnetic shielding material mainly contains surface conduction type and the large class of filled composite type two.Surface conduction type utilizes the methods such as metal paper tinsel, metallikon and plated by electroless plating to make frosting obtain very thin conductive metal layer.Surface coating and surperficial spraying plating are used widely, but these conductive layers easily occur to peel off and delamination through application year in year out.Compared with surface conduction type shielding material, filled-type is that conductive filler and resin matrix are complex as a whole formation shielding material.Conductive filler is generally the large-size fiber shape or flaky material of selecting electric conductivity excellent, as metal fibre or carbon fiber.But often can there is the dispersion problem of non-uniform of conductive fiber in the preparation process of filled-in composite.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of anticorrosion, the finely dispersed computer shield shell of conductive fiber material, comprise screening can and lower screening can, described upper screening can comprises screen storehouse, screen bulkhead, upper conducting resinl mouth, button storehouse, described screen storehouse to be laterally located on this bottom screening can and to be connected with described button storehouse by button bulkhead, interior limit mounting post is provided with outside described screen bulkhead, described upper conducting resinl mouth is located at screening can wall top surrounding, upper limit erection column is provided with inside described upper screening can wall, described lower screening can comprises battery compartment and lower conducting resinl mouth, it is inner that described battery compartment is located at this lower screening can, described lower conducting resinl mouth is located at lower screening can wall top surrounding, lower limit erection column is provided with inside described lower screening can wall.
Described upper screening can and lower screening can surrounding are equipped with fillet.
The beneficial effects of the utility model are:
The utility model conductive plastics computer shield shell can realize dispersed in plastic substrate of carbon fiber, the even coating to carbon fiber knit body can be realized, make it the high conductivity both with metal, the density again with macromolecular material is low, antiseptic property good, wideband, absorption are large and the feature of easily processing, and its shield effectiveness can reach more than 80dB; And its preparation technology is simpler, be easier to control.
