Description
本創作是關於一種防電磁干擾結構,尤指一種具有散熱功能的電子元件防電磁干擾之遮蔽結構。 The present invention relates to an anti-electromagnetic interference structure, and more particularly to an anti-electromagnetic interference shielding structure for an electronic component having a heat dissipation function.
一般的電子設備例如手機、平板電腦或其他的電子裝置等等都會安裝許多電子元件,當電子設備運作或操作時,這些電子元件就會產生一定程度的電磁場,該等電子元件所產生的電磁場之間就會產生相互干擾、阻隔,進而影響電子設備的正常運作,而且電磁波還會向外輻射對人體造成傷害,這種現象即被稱為EMI(Electro Magnetic Interference;電磁波干擾)。 A general electronic device such as a mobile phone, a tablet computer or other electronic device or the like is equipped with a plurality of electronic components. When the electronic device operates or operates, the electronic components generate a certain degree of electromagnetic field, and the electromagnetic field generated by the electronic components Interference and blocking will occur, which will affect the normal operation of electronic equipment, and electromagnetic waves will also cause external damage to the human body. This phenomenon is called EMI (Electro Magnetic Interference).
目前一般防止EMI的方式有水電鍍、電氣電鍍、真空濺鍍及噴塗導電漆等,或直接係在電子元件的外部加上適當的金屬件材質之電磁遮罩以屏蔽電磁波,而由於金屬件遮蔽的方法成本較低且符合當前的環保法規,故最常被使用;常見的電磁遮罩結構為金屬材質如不銹鋼、鋁箔、鐵件或鋁鎂合金等一體成型的罩體或蓋體,該罩體具有頂壁及自頂壁周緣垂直延伸而出的支撐(側)壁。使用時將該罩體罩設(或蓋設)於所需屏蔽的電子元件外側,並透過銲接或其他等方式將支撐壁\固定在電路板上。 At present, the general methods for preventing EMI include water plating, electric plating, vacuum sputtering, and spraying of conductive paint, or directly attached to the outside of the electronic component and an appropriate electromagnetic mask of the metal material to shield the electromagnetic wave, and the metal component is shielded. The method is the most costly and complies with current environmental regulations, so it is most commonly used; the common electromagnetic shielding structure is a one-piece cover or cover made of metal such as stainless steel, aluminum foil, iron or aluminum-magnesium alloy. The body has a top wall and a support (side) wall extending perpendicularly from the periphery of the top wall. In use, the cover is covered (or covered) outside the electronic component to be shielded, and the support wall is fixed to the circuit board by soldering or the like.
但習知的電磁遮罩結構,其僅單純具有遮蔽電磁波的功能。但事實上,電子元件在操作或使用時,除會產生電磁波外,實際使用上,在運作時電子元件仍也會產生熱量,這些熱量被聚集在罩體內無法向外散逸,且金屬材質的電磁遮罩結構的熱傳導速度又太慢,也就是罩體無法有效率的將電子元件產生的熱量向外傳遞出去,將導致電子元件產生的熱量持續增高,造成被罩體罩設的電子元件的壽命短或效能降低。因此如何達到最佳的電磁屏蔽效果及又具有極佳的散熱效果是本創作的課題。 However, the conventional electromagnetic shielding structure has only a function of shielding electromagnetic waves. But in fact, when the electronic components are operated or used, in addition to electromagnetic waves, in actual use, the electronic components will still generate heat during operation, and the heat is concentrated in the cover body and cannot be dissipated outward, and the metal material is electromagnetic. The heat transfer speed of the mask structure is too slow, that is, the cover body cannot efficiently transfer the heat generated by the electronic components outward, which will cause the heat generated by the electronic components to continuously increase, resulting in a short life of the electronic components covered by the cover. Or reduced performance. Therefore, how to achieve the best electromagnetic shielding effect and excellent heat dissipation effect is the subject of this creation.
有鑑於上述問題,本創作之目的在於提供一種達到最佳的電磁屏蔽效果,並具有極佳散熱效率的電子元件防電磁干擾之遮蔽結構。 In view of the above problems, the purpose of the present invention is to provide an anti-electromagnetic interference shielding structure for an electronic component that achieves an optimal electromagnetic shielding effect and has excellent heat dissipation efficiency.
為達上述目的,本創作提供一種電子元件防電磁干擾之遮蔽結構係包括:一蓋體,該蓋體具有一第一側及一第二側,該第一側位置處貼附有至少一熱傳元件,而該第二側接觸至少一電子元件;藉此,透過所述蓋體除可屏蔽電子元件的電磁波外,並可經由熱傳元件將電子元件熱量予以迅速散熱者。 In order to achieve the above object, the present invention provides a shielding structure for preventing electromagnetic interference of an electronic component, comprising: a cover body having a first side and a second side, the first side position being attached with at least one heat The component is transmitted, and the second side contacts the at least one electronic component; thereby, the cover body is shielded from electromagnetic waves of the electronic component, and the heat of the electronic component can be quickly dissipated via the heat transfer component.
