Description
[technical field]
The present invention relates to a kind of portable case of electronic equipment and preparation method thereof, particularly a kind of portable case of electronic equipment and preparation method thereof with electromagnetic wave shielding function.
[background technology]
General regular meeting sent electromagnetic wave when all kinds of portable electron devices were worked, and excessive electromagnetic wave can damage human body.Because mobile phone, notebook computer, personal digital assistant (PDA, Personal Digital Assist) etc. portable electron device uses very extensive in daily life, and more near user's health, therefore may cause more serious harm to the user than general electronic installation.How to prevent of the injury of the electromagnetic wave of portable electron device radiation, become the important technological problems of the industry human body.
[summary of the invention]
In view of this, be necessary to provide a kind of portable case of electronic equipment with electromagnetic wave shielding function.
In addition, be necessary to provide a kind of manufacture method with portable case of electronic equipment of electromagnetic wave shielding function.
A kind of portable case of electronic equipment, it comprises a matrix, a screen and an insulating barrier, and wherein this screen is located at least a portion surface of matrix, and this insulating barrier is located at the surface of screen.
A kind of manufacture method of portable case of electronic equipment, this method may further comprise the steps: form a matrix; Form a screen in the precalculated position of this matrix surface, and make this screen attached to matrix surface; Form an insulating barrier on this screen surface, and make this insulating barrier attached to the screen surface.
Compared with prior art, described portable case of electronic equipment shields by the unwanted electromagnetic wave of its screen to the radiation of portable electron device institute, helps to ensure that the user's is healthy.
[description of drawings]
Fig. 1 is the structural representation of the preferred embodiment of portable case of electronic equipment of the present invention.
Fig. 2 is the cutaway view of Fig. 1 along the II-II line.
[embodiment]
See also Fig. 1 and Fig. 2, the preferred embodiment of portable case of electronic equipment of the present invention is the shell of a mobile phone, and it comprises a matrix 1, a screen 2 and an insulating barrier 3.Wherein screen 2 is located at least a portion inner surface of matrix 1, and insulating barrier 3 is located at the surface of screen 2.
Matrix 1 is made of plastics.The film that screen 2 is made by metal material for one deck, but the alloy of a kind of or above-mentioned more than one metals in its material aluminium (Al), chromium (Cr), silver (Ag), the nickel metals such as (Ni); These screen 2 thickness ranges are that 0.1 micron (μ m) is to 5 microns.The film that insulating barrier 3 is made by insulating material for one deck, its material can be selected one or more the combination in diamond like carbon (DLC), titanium nitride (TiN), the chromium nitride materials such as (CrN) for use; These insulating barrier 3 thickness ranges also are 0.1 micron to 5 microns.
The method that the preferred embodiment of portable case of electronic equipment manufacture method of the present invention is promptly made above-mentioned portable case of electronic equipment, this manufacture method may further comprise the steps:
At first, form the matrix 1 of a mobile phone outer casing, this matrix 1 is made of plastics.When matrix 1 was plastics, this step is mainly and adopts the mode of ejection formation was matrix 1 with plastic shaping directly.Can further carry out surface treatment to this matrix 1 after the moulding, satisfying the outward appearance chromaticness needs of shell, and the evenness that increases matrix 1 makes the follow-up screen 2 that is formed on its inner surface have high tack.This surface-treated method can adopt one or more compound modes that comprise in plating, oxidation, application or the vacuum coating.
Secondly, the precalculated position on this matrix 1 inner surface forms a screen 2, and this screen 2 is made by the alloys a kind of or above-mentioned more than one metals in the metals such as aluminium, chromium, silver, nickel, and its thickness range is 0.1 micron to 5 microns.Adopt the method for sputter on the inner surface of matrix 1, to form this screen 2 in the actual production, make simultaneously on the inner surface of this screen 2 attached to matrix 1.During this screen 2 of sputter, with matrix 1 is base material, alloys a kind of or above-mentioned more than one metals in the metals such as aluminium, chromium, silver, nickel are target, adopt radio frequency (RF) energy source to excite argon gas electricity slurry with 30～100 standard ml/min (StandardCubic Centimeter per Minute, SCCM) mass flow is impacted target, the material splash of target material surface is come out, and being deposited into base material is matrix 1 surface.In addition, other relevant parameter is during sputter: base material meets rf bias (RF bias voltage)-50～200V or AC bias (AC bias voltage)-50～200V, and coating temperature can be controlled between the room temperature to 150 ℃, and coating chamber pressure is 1 * 10
-5～10 * 10
-5Pascal (Pa).
At last, form an insulating barrier 3 on these screen 2 surfaces.This insulating barrier 3 is made by one or more the combination in diamond like carbon (DLC), titanium nitride (TiN), the chromium nitride materials such as (CrN), and its thickness range is 0.1 micron to 5 microns.Can also adopt the method for sputter on the surface of screen 2, to form this insulating barrier 3 in the actual production, on seasonal this insulating barrier 3 surface attached to screen 2.
When use was equipped with the mobile phone of preferred embodiment of portable case of electronic equipment of the present invention, the unwanted electromagnetic wave of screen 2 maskable mobile phone institutes radiation ensured that the user's is healthy.Simultaneously, the insulating barrier 3 that covers screen 2 surfaces can prevent that screen 2 from contacting with the mobile phone intraware, thereby prevents that the mobile phone internal circuit from forming short circuit by the screen 2 that metal material constitutes.In addition, because custom placed headward position with the one side at display screen and keyboard place when most users used mobile phone, therefore can only on the inner surface of display screen on the matrix 1 and keyboard place one side, screen 2 and insulating barrier 3 be set, to reduce manufacturing cost.
The preferred embodiment that is appreciated that portable case of electronic equipment of the present invention is equally applicable to the portable electron device that notebook computer, personal digital assistant (PDA, Personal Digital Assist) wait other kind.
