Method for achieving electromagnetic compatibility of tablet computer with plastic shell

Abstract

The invention provides a method for achieving electromagnetic compatibility of a tablet computer with a plastic shell. The shell of the reinforced tablet computer comprises a lower cover and an upper cover which are manufactured through injection molding. Six screw through holes are formed in the periphery of the upper cover, and the periphery of the lower cover is correspondingly provided with six screw holes. The upper cover and the lower cover are fastened together through self-tapping screws. In order to allow the plastic shell of the reinforced tablet computer to be conductive, and the surface of the shell, the inner surface of the lower cover, the contact edges of the upper cover and the lower cover, the outer surface of the lower cover, the inner surface of the upper cover, the contact edges and grooves of the upper cover and the lower cover and the outer surface of the upper cover are electroplated. The method has the advantages that the shell of the reinforced tablet computer is made of plastics, overall weight of the tablet computer is reduced effectively, the surface of the plastic shell is plated, the gap between the lower cover and the upper cover after the two are assembled is sealed, touch screen positions with large electromagnetism leakage is shielded, and the reinforced tablet computer with the plastic shell can satisfy the electromagnetic compatibility requirements of national military standard.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method for realizing electromagnetic compatibility of a tablet computer with a plastic casing. Background technique [0002] Tablet computers can be divided into two types: civilian use and reinforcement. Among them, the casings of civilian tablet computers are mostly made of plastic materials. Plastics are non-conductive and cannot meet the electromagnetic shielding properties of computers. In order to make the tablet computers with plastic casings meet this characteristic , the usual way is to carry out vacuum coating or spray conductive paint on the surface of the plastic case, so that the plastic case becomes a conductor to achieve the effect of electromagnetic shielding. Electromagnetic shielding only meets the requirements of ordinary civilian standards, but a tablet computer with a plastic casing is very light in weight. [0003] Reinforced tablet computer...

[0002] Tablet computers can be divided into two types: civilian use and reinforcement. Among them, the casings of civilian tablet computers are mostly made of plastic materials. Plastics are non-conductive and cannot meet the electromagnetic shielding properties of computers. In order to make the tablet computers with plastic casings meet this characteristic , the usual way is to carry out vacuum coating or spray conductive paint on the surface of the plastic case, so that the plastic case becomes a conductor to achieve the effect of electromagnetic shielding. Electromagnetic shielding only meets the requirements of ordinary civilian standards, but a tablet computer with a plastic case is very light in weight

[0003] Reinforced tablet computers are mostly used in relatively harsh environments. The machine needs to meet the requirements of the national military standard for electromagnetic shielding. The casing of the reinforced tablet computer is mostly made of metal, and metal is an electrical conductor, so the metal casing itself has good Conductivity to achieve electromagnetic shielding effect, and the tablet computer with metal casing can meet the requirements of the national military standard for electromagnetic compatibility, but the weight of the machine with metal casing is relatively heavy
