Abstract
The invention discloses a plastic panel which is characterized in that: the panel comprises a panel substrate and an electromagnetic shielding body, wherein, the substrate is a conductive plastic piece; and the electromagnetic shielding body is fixed on the lateral of the substrate. Compared with the prior art, the plastic panel overcomes the shortcomings that the metal panel of the prior art has a complicated structure, needs a special mould and secondary mechanical processing, has high processing cost and is inconvenient to insert in boxes and transportation due to heavy weight, and the conductive plastic panel substrate is formed by injection, thereby having high production efficiency and reducing the weight of the panel and the processing cost.
Description
Technical field
The present invention relates to the structure electromagnetic shielding in electronic product field, relate in particular to a kind of plastic front board.
Background technology
Subrack structure is used in the telecommunications field in a large number at present, and subrack is for a kind of construction unit of installing in a plurality of plug-in units and connector and can pack into frame, the cabinet etc.But subrack comprises the panel of a plurality of plugs usually, and panel, subrack machine frame and other plug-in units have constituted a complete structure function and electromagnetic shielding integral body.
The matrix of panel is metal material at present, and shielding finger or conductive fabric are installed in the side of matrix, and reed or conductive fabric contact with the side structure good conductive during installation, have formed a complete shield.The deficiency of this version is: because the panel construction complexity, metal decking needs particular manufacturing craft, and needs secondary mechanical processing, and processing cost is higher; Metal decking weight is heavier, and subrack moves transportation etc. and makes troubles.
A kind of mode that solves metal decking at present is that panel base is used plastic material, and plates conductive layer at matrix surface, and shielding finger is installed in the side, is the Chinese patent application " a kind of panel making method " of CN1851828 as publication number.This method has the following disadvantages: plastic material electroplating technology complexity; Manufacturing process is more.
Summary of the invention
Technical problem to be solved by this invention is: overcome that metal decking needs particular manufacturing craft in the prior art, and secondary mechanical processing, processing cost is higher; Metal decking weight is heavier, and subrack moves problem and the defective that transportation waits makes troubles, and a kind of plastic front board that is used for the communication subrack is provided.
The present invention adopts following technical scheme:
The plastic front board that the present invention proposes, comprising: panel base and electromagnetic shield, described matrix are conductive plastic part, and described electromagnetic shield is fixed on the side of matrix.
Preferably, conductive plastic part adopts and to add conductive fiber and particle is made in plastic basis material.
Preferably, described plastic basis material is one of following macromolecular material: polycarbonate PC, engineering plastics ABS, polypropylene PP.
Preferably, described conductive fiber is stainless steel fibre, aluminum alloy fiber, iron fiber, monel metal fiber, carbon fiber or nickel-coated carbon fibers.
Preferably, described particle is carbon dust, graphite, non-metallic fibers metallizing layer, silver powder, copper powder, aluminium powder, non-metallic particle metallizing.
Preferably, described electromagnetic shield is: conductive fabric, reed, conductive rubber or conductive plastics.
Adopt plastic front board of the present invention, compared with prior art, overcome metal decking complex structure of the prior art, need particular manufacturing craft, and need secondary mechanical processing, processing cost is higher; It is heavier to have overcome metal decking weight, and subrack moves transportation etc. and makes troubles; The injection mo(u)lding of conductive plastics panel base, the production efficiency height has reduced panel weight and processing cost.
