于是,必须重新设计介面卡上的引线和电子元件的配置,所完成的产品无法使用而报废。 Then, you must re-design configuration leads and electronic components on the interface card, the finished product can not be used and scrapped. 传统的补救方法是额外配置导电泡棉(gasket )、吸波材料(absorber )、铜箔、铝箔等以阻绝电石兹波。 The traditional remedy is additional configuration conductive foam (gasket), absorber (absorber), copper, aluminum, etc. in order to block the calcium carbide Zibo. 然而,这些方法不仅造成产 However, these methods are not only caused production

品销售的延宕,并衍生附加的检修费用,或较为昂贵而难以实施。 Product sales of delays and additional maintenance costs derivative, or a more expensive and difficult to implement. 再者, 上述部分措施效果欠佳,无法直接解决电磁波辐射问题。 Moreover, some of these measures ineffective, can not solve the problem of electromagnetic radiation directly.

对以上现有技术或现有产品所存在的缺陷应设法予以排除。 Of the above prior art or existing product defects deserves to be excluded.

散热组件20由多片散热鳍片21 (heatsink)组成,其设置在芯片组ll 上,用以对芯片组11进行散热。 Cooling assembly 20 by a plurality of pieces of cooling fins 21 (heatsink), whose set on the chipset ll, 11 for chipset cooling. 固定板30装设在印刷电路板10的侧边, 且固定板30上设有螺孔31,可供外部螺钉穿过,以使印刷电路板10插置固定在电脑机壳IOO的介面卡定位槽110处。 A fixing plate 30 mounted on the side of the printed circuit board 10, and the screw 31 is provided on the fixing plate 30, for external screws through to the printed circuit board 10 is fixed interposed interface card located in the computer's chassis IOO slot 110.

接地件40由导电金属制成,其两端分别接触或顶抵于散热组件20和固定板30。 Grounding member 40 is made of a conductive metal, its ends were exposed to heat or top against a fixed plate assembly 20 and 30. 接地件40对应固定板30的一端设有与螺孔31对应的通孔42, 而与散热组件20相接的一端则弯折出抵压部43 ,借以增进抵触连接的效果。 40 corresponding to the fixed end of the ground plate 30 is provided with corresponding holes 31 through holes 42, and one end of the radiator assembly 20 is in contact with the bent portion 43 of the presser, in order to enhance the effect of conflict connected. 接地件40的中段适当处凹陷形成弹性段41,可适应散热組件20和固定板30的组装公差,以使接地件40很好地顶抵两者。 Appropriate middle ground member 40 is recessed to form an elastic section 41 can be adapted to the cooling unit 20 and the fixed plate assembly tolerances 30 to 40 so that the ground well against the top two.

基于电子辐射循最短途径导地的特性,芯片组11工作时所产生的电磁波辐射将通过散热组件20上的散热鳍片21传导至接地件40,继而由接地件40再导通至电脑机壳100,而将电磁波辐射导出。 Based on electron radiation through the shortest way to lead to the characteristic, electromagnetic radiation generated by the chipset will work 11 through the cooling fins 20 on the component 21 is conducted to the ground 40, followed by the ground 40 again turned to the computer chassis 100, and the electromagnetic radiation exported.

接着,参考图4与图5来说明本发明的第二优选实施方式。 Next, with reference to FIGS. 4 and 5 will be described a second preferred embodiment of the present invention. 第二优选实施方式与前一优选实施方式的组成大致相同,主要包括印刷电路板10、 散热组件20、固定板30与接地件50。 The second preferred embodiment is composed of the previous preferred embodiment is substantially the same, including a printed circuit board 10, heat dissipation assembly 20, the grounding member 30 and the fixing plate 50. 印刷电路板IO上设有芯片组11,散热组件20由多片散热鳍片21组成,它们设于芯片组11上。 Is provided on the printed circuit board 11 IO chipset, cooling assembly 20 by a plurality of fin sheet 21 composed of 11 are disposed on the chipset. 固定板30设于印刷电路板10的一侧,以使印刷电路板10插置固定在电脑机壳100的介面卡定位槽110上。 Fixing plate 30 is provided on one side of the printed circuit board 10 to the printed circuit board 10 interposed fixed on computer chassis interface card positioning grooves 110 100. 不同的是,第二优选实施方式中的固定板30于适当处开设有圆孔32,而接地件50优选可选用长轴固定螺钉。 The difference is that the second preferred embodiment of the fixing plate 30 has a hole opened at the appropriate place 32, and the grounding member 50 is preferably the long axis of the fixing screws can be used. 于是,当印刷电路板10装配在电脑机壳IOO的定位槽110上后,将接地件50穿过圆孔32, 以锁接或顶抵的方式与散热组件20接触。 Thus, when the printed circuit board 10 mounted on the computer chassis IOO positioning groove 110 after the grounding member 50 through the hole 32 to lock pick or top manner against cooling components 20 contacts. 因此,芯片组11工作产生的电f兹波可依序经由散热组件20和接地件50而被传导至固定板30和电脑机壳亂 Therefore, the chip set 11 operates to generate electrical f Zibo cooling components can be sequentially via 20 and the ground 50 is transmitted to the fixed plate 30 and the computer chassis chaos

关于本发明的第三优选实施方式,请参考图6至图8,该实施方式是针对介面卡上的散热结构进行改良的设计。 About a third preferred embodiment of the present invention, refer to FIG. 6 to 8, this embodiment is carried out for the improvement of the thermal structure design interface card. 第三优选实施方式应用在印刷电路板10上,而此印刷电路板10上至少设有一芯片组11,并被设置在电脑机壳100内。 The third preferred embodiment applied to the printed circuit board 10, and this printed circuit board with at least one chip set 11 10, and is set in the computer chassis 100. 第三优选实施方式主要披露了一种应用于介面卡的散热组件60,其装配在芯片组ll之上,它主要包括多片散热鳍片61和活动鳍片62。 Disclosure of the third preferred embodiment is mainly applied to a thermal interface card assembly 60, which is fitted on the chipset ll, which mainly comprises a multi-piece fin 61 and fins 62 activity. 散热鳍片61以间隔排列的形式成形设置,以对芯片组11进行散热。 Fin 61 shaped in the form of spaced set to 11 cooling for the chipset. 活动鳍片62的作用等同于散热鳍片,其邻设在最侧边的散热鳍片61的一侧, 活动鳍片62的一端延伸有传导部63。 Action activity fin 62 is equivalent to the heat sink, which is located adjacent the side of the side of the cooling fins 61, one end of the movable fin 62 extends conduction part 63. 特别的是,活动鳍片62必要时可相对芯片组ll旋转。 In particular, can be rotated relative to the chipset ll fin 62 necessary activities. 于是,当对印刷电路板10完成组装操作后,散热组件60上的活动鳍片62即可旋转,直到搭触电脑机壳100为止,以便将芯片组11工作时所产生的电磁波经活动鳍片62而导通至电脑机壳100,活动鳍片62的中段处设有弹性段64,且活动鳍片62的一端弯折有传导部63,借以增进与电脑机壳100的接触效果。 Thus, when the printed circuit board 10 to complete the assembly operations, activities radiating fin assembly 60 to rotate on the 62 until the take-touch computer chassis 100 up to 11 chipsets electromagnetic waves generated by the work through activities fins 62 is turned to the computer chassis 100, activity in the middle of the fin 62 is provided with elastic segment 64, and the bent end of the movable fins 62 with a conductive portion 63, in order to enhance the effect of the computer chassis 100 contacts.

基于电子辐射循最短途径导地的特性,本发明的介面卡使用接地件将电磁波辐射传递至电脑机壳,借以排除产品中过量电磁波辐射的问题。 Based on electron radiation through the shortest way to lead to the characteristics of the present invention uses a ground interface card members will transfer to the computer chassis electromagnetic radiation, in order to exclude the products in question in excess of electromagnetic radiation. 本发明所4皮露的优选实施方式能快速而有效地导出电^兹波辐射,并具有成本低廉、组成元件简单、易于实施等优点。 A preferred embodiment of the present invention can 4 exposed skin quickly and efficiently exporting electricity ^ 兹波 radiation, and having a low cost, simple constituent elements, easy to implement and so on.

以上仅对本发明的优选实施方式进行了描述,显然,本发明不限于所述实施方式,凡在本发明的构思范围内作出的等同变换与修饰皆应落入本发明权利要求所要求保护的范围。 Above is only a preferred embodiment of the present invention have been described, it is clear that the invention is not limited to the embodiment of equivalents and modifications within the spirit where the scope of the invention are made should fall within the claims of the invention claimed range .
