(2) background technology
Generally speaking, an electronic installation has a shell protecting inner electronic component, and has a dismountable door closure on shell usually, to make things convenient for the inner member of replacing electronic device.
At first see also Fig. 1, this figure is the schematic diagram of expression one known electronic device housing.With a known notebook computer is example, as shown in Figure 1, is provided with a plurality of outstanding supporting pad S in a shell 1 bottom, in order to stably to support above-mentioned notebook computer.In addition, have a dismountable door closure 2 in shell 1 central authorities, and door closure 2 is to be locked on the shell 1 by screw 3; Wherein, when the element of desiring to change notebook computer inside (as memory), can open aforementioned door closure 2 and be beneficial to implement the action of installing or dismantling.Generally speaking, known door closure 2 is provided with conduction bubble continuous (Conductive Shielding Gasket) usually around it, conduction bubble silk floss can closely contact with shell 1 when door closure 2 is closed, because general notebook computer is to use the made shells of material such as almag, therefore can by door closure 2 and shell form shielding and lower the electromagnetic interference that internal electronic element produced (Electromagnetic Interference, EMI).
Yet, along with making rapid progress of computer technology and semiconductor technology, the processing speed of known electronic installation (as notebook computer) internal integrated circuit element (as central processing unit, memory etc.) and function also constantly promote, simultaneously its heat energy that is produced of following also more and more higher.Thus,, and cause it to exceed the limiting temperature that standard specification can allow, so will cause the bad of product and be unfavorable for that personnel use in surface temperature lifting apace of electronic device housing owing to be heated easily.As previously mentioned, though known door closure 2 has the consideration that alleviates electromagnetic interference (EMI), and can't solve above-mentioned serious day by day problems of excessive heat effectively.
(3) utility model content
In view of this, the purpose of this invention is to provide a kind of door closure design with multifunctional protection sheet, be applicable to an electronic device housing, not only can prevent electromagnetic interference (Electromagnetic Interference, EMI) and static discharge (Electro Static Discharge, ESD), but uniform heat conduction and have heat insulating function is simultaneously used and is avoided the surface temperature of shell too high.
The invention provides a kind of electronic device housing door closure, comprise a door body, a heat shield, a conductive layer and an insulating barrier.Wherein, described heat shield is laid in the inner surface of door body.In addition, conductive layer is laid in the surface of heat shield, with lower electromagnetic interference (Electromagnetic Interference, EMI) and static discharge (Electro Static Discharge, ESD).In addition, insulating barrier is laid in the surface of aforementioned conductive layer, electrically contacts with conductive layer to intercept the electronic installation inner member.The heat energy that electronic installation produces is intercepted by heat shield, makes the door body surface temperature keep stable.
Yet for above-mentioned purpose of the present invention, characteristics and advantage can be become apparent more, cited below particularlyly go out a preferred embodiment, and conjunction with figs. is elaborated as follows.
(4) description of drawings
Fig. 1 is the schematic diagram of the known electronic device housing of expression;
Fig. 2 is the schematic diagram of electronic device housing door closure among expression the present invention;
Fig. 3 is another schematic diagram of electronic device housing door closure among expression the present invention;
Fig. 4 is the enlarged drawing at A place in the presentation graphs 3.
(5) embodiment
Please consult Fig. 2 and Fig. 3 simultaneously, this two figure is the schematic diagram of electronic device housing door closure among expression the present invention.As shown in the figure, door closure 2 mainly comprises a door body 20 and a multifunctional protection sheet 21, wherein has perforate 201 on the door body 20, passes perforate 201 by screw 3 door closure 2 is locked on the aforementioned electronic.In addition, also be provided with a plurality of protuberances 202, use with the electronic device housing engaging getting loose avoiding in the side of door body 20.
Particularly, aforementioned multifunctional protection sheet 21 is made up of an insulating barrier 211, a conductive layer 212 and a heat shield 213.Heat shield 213 is the inner surfaces that are laid in door body 20, and in present embodiment, above-mentioned heat shield 213 is made by minute aperture PU condensate (PORON) or chlorinated rubber (CR).Wherein, when electronic installation inside has a thermal source (transmission of heat energy is shown in the direction of arrow of Fig. 3), heat shield 213 can block heat energy effectively, causes the too high problem of surface below temperature because of being heated to avoid door body 20.
In addition, please consult Fig. 3 and Fig. 4 simultaneously, in order effectively to prevent known electromagnetic interference (Electromagnetic Interference, EMI) and static discharge (Electro Static Discharge, ESD), the present invention lays a conductive layer 212 in aforementioned heat shield 213 tops, and this conductive layer 212 is an aluminium foil in present embodiment, yet also can use Copper Foil or general known conductive material.When door closure 2 combines with electronic installation, above-mentioned conductive layer 212 not only can form shielding with shell and disturb (Electromagnetic Interference to lower aforementioned electromagnetic effectively, EMI) and static discharge (Electro Static Discharge, ESD), simultaneously can will heat energy be led around the door closure 2 fifty-fifty, avoid because of the heat energy concentrations causes the temperature of regional area too high, therefore have rapidly and the effect of uniform heat conduction.
Fig. 4 is the enlarged drawing at A place in the presentation graphs 3, and wherein conductive layer 212 is to be laid in surface, heat shield 213 top, and insulating barrier 211 then is laid in surface, aforementioned conductive layer 212 top.In present embodiment, the material of aforementioned dielectric layer 211 is polyester film (MYLAR), yet also can use other insulation materials.By above-mentioned insulating barrier 211 is set, can block internal electronic element effectively and contact with conductive layer 212, take place to avoid situation of short circuit.
In sum, the present invention is by a multifunctional protection sheet is set in door body 20, wherein heat shield 213 can effectively block heat energy, has elasticity owing to minute aperture PU condensate (PORON) and chlorinated rubber (CR) are soft, therefore when door closure is closed, can make the aluminium foil of conductive layer 212 can press close to built-in system fully and form good shielding, have the effect that lowers electromagnetic interference (EMI).Wherein, door closure design of the present invention is the memory door closure that is specially adapted to as on the known notebook computer, not only can avoid the surface temperature of shell door closure overheated, simultaneously can conveniently replaced inner member.
In addition, the insulating barrier of aforementioned multifunctional protection sheet, conductive layer and heat shield are the mode combinations that attaches by surface mount, therefore the present invention not only has simple structure and advantage with low cost, and can lower electromagnetic interference (EMI) and Electrostatic Discharge effectively, especially having can be rapidly and the effect of uniform heat conduction, has improved the too high problem of known electronic device housing door closure surface temperature significantly.
Though disclose as above with preferred embodiment by the present invention; yet it is not in order to limit scope of the present invention; any person skilled in the art person without departing from the spirit and scope of the present invention; all equivalence changes or equivalence is replaced when making, so protection scope of the present invention is when looking being as the criterion that accompanying Claim defines.
