The invention discloses a method for allowing a laptop interface to achieve electromagnetic compatibility and to be prevented from getting wet in rain. A silicone rubber door is processed through the wire mesh and conductive coating dual-layer shielding method, the surface of a silicone rubber material is coated with a conductive coating in a spray mode, a wire mesh layer is embedded in the silicone rubber material, a piece of wire mesh extends to the surface layer of the silicone rubber door, and the wire mesh and conductive coating dual-layer shielding is achieved; shielding layers and a machine shell are pressed tightly through the elasticity of silicone rubber; the conductive coating makes contact with the periphery of the machine shell after the silicone rubber door is closed, and the first layer of shielding is formed; the wire mesh makes contact with the machine shell under the preload of the silicone rubber door, and the second layer of shielding is formed. By means of the technology, while the elasticity of the silicone rubber material is fully utilized to achieve interface sealing, the requirement for electromagnetic compatibility of the military laptop interface can be met; due to the elasticity of the silicone rubber material, the requirements for rain prevention and sealing are met.
Description
Technical field
The present invention relates to computer field of electromagnetic compatibility, be specifically related to a kind of method of notebook Interface realization electromagnetic compatibility and rainproof.
Technical background
More military computer is applied in and compares in rugged environment, and to the requirement of electromagnetic shielding in demand fulfillment national military standard, the computer of especially field use, also needs the requirement meeting rainproof.Consider equipment interoperability, military computer often adopts the non-air plug mouths such as standard USB port, audio port, which results in the difficulty of interface electromagnetic compatibility and rainproof.Silicon rubber Men Yinqi is cheap, is easy to usely widely used in the interference prevention of civilian computer, but non-conductive because of it, cannot meet the EMC Requirements of military computer.Employing electric silica gel cost is higher and resistance is comparatively large, and screening effectiveness is low, also cannot meet the requirement of military computer height electromagnetic shielding.
Silicon rubber is transparent or milky granular solids.Have open loose structure, adsorptivity is strong, can adsorb many kinds of substance.As: absorb moisture, hygroscopic capacity about reaches 40%.Silicon rubber has the performances such as excellent thermal endurance, cold resistance, dielectricity, resistance to ozone and resistance to atmospheric aging, and the outstanding performance of silicon rubber is that serviceability temperature is broad, can at-60 DEG C (or lower temperature) to+250 DEG C (or higher temperature) Long-Time Service.But the mechanical performances such as the tensile strength of silicon rubber and tearing toughness are poor, its physical and mechanical properties is not as good as most of synthetic rubber at normal temperatures, and except nitrile silicon, fluorosioloxane rubber, general silicon rubber oil resistant, solvent resistance is not good enough, therefore silicon rubber should not be used for the occasion of usual terms, but be highly suitable for many specific occasions.
Summary of the invention
The technical problem to be solved in the present invention is: in order to meet the requirement of the shielding of military computer interface electromagnetic and rainproof, the invention provides a kind of method that silicon rubber door realizes notebook interface electromagnetic compatibility and rainproof, by the process of the method to notebook interface, electromagnetic compatibility and the rainproof requirement of notebook can be met simultaneously.
The technical solution adopted in the present invention is:
A kind of method of notebook Interface realization electromagnetic compatibility and rainproof, silicon rubber door adopts woven wire to add the process of conductive coating double layer screen method, at silastic material surface spraying conductive coating, and at the inner built-in metal silk screen layer of silastic material, woven wire extends to silicon rubber door top layer, forms the double layer screen that woven wire adds conductive coating; Silicon rubber elastic is utilized to realize screen and casing compresses; After silicon rubber door is closed, conductive coating contacts with casing surrounding, forms one deck shielding; Woven wire forms the second layer with chassis contact and shields under silicon rubber door pretightning force.
Described notebook interface selects the components and parts of band metal screen layer, and metal screen layer, by ground strip, overlaps with casing, realizes good earth.
Ground strip material is spring-piece type structure, and adopt beryllium-bronze material, one end is provided with fixing hole, is fixed on the metal screen layer of interface, and the other end is cantilever, overlap joint interface metal shell.This ground strip directly compresses interface metal screen layer, shortens grounding path, to ensure the good earth of interface screen.
The silicon rubber door of a kind of notebook Interface realization electromagnetic compatibility and rainproof, the structure of described silicon rubber door comprises: the conductive coating on top layer, be arranged at the sealing flange at silicon rubber door edge, be arranged at the woven wire in centre position, woven wire extends to the top layer of silicon rubber door; Conductive coating and woven wire form shielding construction, realize the double layer screen of interface; Sealing flange realizes the sealing of interface.
Beneficial effect of the present invention is: adopt technology of the present invention, while sealing joint can being realized making full use of silicon silastic material elasticity, meet the EMC Requirements of military notebook interface, and utilize the elasticity of silastic material, realize the requirement of weather seal.
