Embodiment approach

[0031] The preferred implementation mode of the present invention is:

[0032] The conductive plastic substrate of the upper cover 101 and the lower cover 102 uses a mixed material of PC+ABS, and the filler material uses nickel-plated carbon fiber, and the filler is evenly distributed in the middle of the upper cover 101 and the lower cover 102 by injection molding, and the upper cover 101 and the lower cover The cover 102 is directly overlapped with a plane, and is fastened and installed through the screw mounting holes 401, and the distance between the screw mounting holes is controlled at 50 mm.

Abstract

The invention discloses a plastic shield casing, comprising an upper cover and a lower cover, one of which is a conductive plastic piece, the other one is a metal piece or a conductive plastic piece. By adopting the plastic shield casing, the invention has advantages of without need of machining treatment, good moulding consistency, high production efficiency and low cost, overcomes the disadvantages of production complexity of the metal shield casing and simplex appearance in the prior art, also improves the electromagnetic shielding effect of the casing. By utilizing reasonable filler with better performance, the combination form of the upper and the lower covers is more abundant, the lap joint form of the casing is simplified to avoid increase of lap joint gap depth and overlap area. The plastic shield casing can be applied to structure electromagnetic shielding of electronic products.

Description

technical field [0001] The invention relates to structural electromagnetic shielding in the field of electronic products, in particular to a plastic shielding casing. Background technique [0002] At present, electronic products have higher and higher requirements for electromagnetic shielding and product appearance. Traditional plastic casings can give people a satisfactory appearance but have no electromagnetic shielding function; although metal shielding casings have electromagnetic shielding functions, the processing is more complicated. Its shape cannot be changed arbitrarily. [0003] At present, one method of electromagnetic shielding for plastic casings is to put conductive grids in the plastic parts of the casing, or to electroplate or spray conductive paint on the surface, such as the Chinese utility model patent "Household Electrical Appliances with Electromagnetic Shielding Function" with patent number 98249814.4 This method needs to use conductive cloth for shi...
