Electromagnetic fields generated by electronic components may interfere with each other and block, so-called Electro-Magnetic Interference (EMI), which causes electronic components to malfunction and affect signal transmission. Quality. At present, methods for preventing electromagnetic interference on the market include water plating, electric plating, vacuum sputtering, and spraying of conductive paint, or direct use of metal shielding effects, such as stainless steel, aluminum foil, iron or aluminum-magnesium alloy. . Among them, the direct shielding by metal parts is most commonly used because of its low cost and compliance with current environmental regulations.
圖1為習知之一種遮蔽裝置之分解圖，請參照圖1所示，遮蔽裝置1係應用於一電路板P，且包括一支架11以及一遮蔽蓋體12。支架11通常係利用焊接的方式固定於電路板P，而隨所需遮蔽之電子元件的形狀、尺寸及擺放位置，改變支架11之構型，於此支架11係為格子狀。遮蔽蓋體12包括一頂板121及由該頂板四周邊緣向下延伸的側板122，頂板121會與支架11相抵觸以支撐遮蔽蓋體12，側板122則與支架11卡合，使遮蔽蓋體12與電路板P之間形成一容置空間。最後，將遮蔽蓋體12固定於電路板P上，使遮蔽蓋體12穩固地覆蓋於安裝在電路板P上的電子元件外部，進而完成遮蔽裝置1的設置。1 is an exploded view of a conventional shielding device. Referring to FIG. 1 , the shielding device 1 is applied to a circuit board P and includes a bracket 11 and a shielding cover 12 . The bracket 11 is usually fixed to the circuit board P by soldering, and the configuration of the bracket 11 is changed according to the shape, size and placement position of the electronic components to be shielded, and the bracket 11 is lattice-shaped. The shielding cover 12 includes a top plate 121 and a side plate 122 extending downward from the peripheral edge of the top plate. The top plate 121 is in contact with the bracket 11 to support the shielding cover 12, and the side plate 122 is engaged with the bracket 11 to cover the cover 12 An accommodation space is formed between the circuit board P and the circuit board P. Finally, the shielding cover 12 is fixed on the circuit board P, so that the shielding cover 12 is stably covered on the outside of the electronic component mounted on the circuit board P, thereby completing the setting of the shielding device 1.
然而習知技術將遮蔽蓋體12遮蔽罩蓋於電路板P上之電子元件後，不易拆卸，以致倘若日後要維修或更換電子元件時，需要先耗費大量的工時將遮蔽蓋體12拆除，過程頗浪費人力成本。再者，靠近支架11內緣之電子元件因作業迴旋空間有限，另產生不易維修的問題。此外，就材料成本而言，若電路板P之形狀或電子元件擺放位置改變，支架11也必須重新製作，不易量產且耗費成本。However, the conventional technology shields the cover 12 from the electronic components on the circuit board P, and is not easy to disassemble, so that if the electronic components are to be repaired or replaced in the future, it takes a lot of man-hours to remove the shielding cover 12. The process is a waste of labor costs. Moreover, the electronic components near the inner edge of the bracket 11 have a problem of being difficult to maintain due to the limited space of the work swirling. In addition, in terms of material cost, if the shape of the circuit board P or the position of the electronic component is changed, the bracket 11 must be reworked, which is not easy to mass-produce and costly.
因此，如何提供一種可量產且易拆解的遮蔽裝置，其不僅可利於日後更換或維修電子元件，且適於料件標準化的製程設計，同時節省人力及製造成本，已成為一重要課題。Therefore, how to provide a mass-produced and easy-to-disassemble shielding device, which not only facilitates replacement or maintenance of electronic components in the future, but also is suitable for process design of material standardization, and saves manpower and manufacturing costs, has become an important issue.

以下將參照相關圖式，說明依據本發明較佳實施例之遮蔽裝置，其中相同的元件將以相同的參照符號加以說明。The shielding device in accordance with the preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals.
圖2A與圖2B分別為本發明第一實施例之一種遮蔽裝置之組合圖與分解圖。請參照圖2A與圖2B所示，遮蔽裝置2係應用於一電路板P，較佳係為一印刷電路板。遮蔽裝置2包括一遮蔽蓋體21以及多數卡扣件22。2A and 2B are respectively a combined view and an exploded view of a shielding device according to a first embodiment of the present invention. Referring to FIG. 2A and FIG. 2B, the shielding device 2 is applied to a circuit board P, preferably a printed circuit board. The shielding device 2 includes a shielding cover 21 and a plurality of fastening members 22.
遮蔽蓋體21具有多數穿孔211，然其穿孔211數目並無特別限制，端視電路板P之形狀或電子元件擺放位置的需要，而以能確實固定遮蔽蓋體21於所欲覆蓋之位置且能避免不穩或搖晃為原則。在本實施例中，係以遮蔽蓋體21具有四個穿孔211為例，且各側分別具有一穿孔211。然在其他實施例中，遮蔽蓋體21可具有例如2個或8個穿孔211，前者係分別設置於遮蔽蓋體21之對應兩側，而後者則係每側分別具有兩個穿孔211。The shielding cover 21 has a plurality of perforations 211. However, the number of the perforations 211 is not particularly limited, and the shape of the circuit board P or the position of the electronic component is required to be fixed, so as to securely fix the cover 21 to the desired position. And can avoid the principle of instability or shaking. In this embodiment, the shielding cover 21 has four through holes 211 as an example, and each side has a through hole 211. In other embodiments, the shielding cover 21 may have, for example, two or eight perforations 211, the former being respectively disposed on opposite sides of the shielding cover 21, and the latter having two perforations 211 on each side.
遮蔽蓋體21係覆蓋電路板P。在此所稱之覆蓋可指一物體表面積上的一部分即可，而不限面積大小，是以，遮蔽蓋體21可僅覆蓋電路板P上之一電子元件，例如部分地覆蓋，亦可以完全覆蓋電路板P，本發明在此不限。遮蔽蓋體21之一側壁212具有一外延伸部213。請參考圖2B所示，在本實施例中，外延伸部213係例如由側壁212之下緣向遮蔽蓋體21的外側方向水平延伸，是以，外延伸部213可形成類似沿側壁212環繞且水平突出的裙板。在本實施例中，外延伸部213係具有與遮蔽蓋體21相同的長度，以提供較大的接觸面積，然而，在本發明其他實施例中，各外延伸部213可分別具有部分遮蔽蓋體21的長度，例如遮蔽蓋體21的二分之一。The shielding cover 21 covers the circuit board P. The term "covering" as used herein may refer to a portion of the surface area of an object, and is not limited in area. Therefore, the shielding cover 21 may cover only one electronic component on the circuit board P, for example, partially covered or completely Covering the circuit board P, the present invention is not limited thereto. One side wall 212 of the shielding cover 21 has an outer extension 213. Referring to FIG. 2B , in the embodiment, the outer extension portion 213 extends horizontally from the lower edge of the side wall 212 toward the outer side of the shielding cover 21 , so that the outer extension portion 213 can be formed to be similar to surround the side wall 212 . And the horizontally protruding apron. In the present embodiment, the outer extension portion 213 has the same length as the shielding cover body 21 to provide a larger contact area. However, in other embodiments of the present invention, each outer extension portion 213 may have a partial shielding cover, respectively. The length of the body 21, for example, covers one-half of the cover 21.
在本實施例中，穿孔211係形成於外延伸部213。詳細而言，穿孔211可例如為長方形貫穿外延伸部213的通道，且其三面包覆在外延伸部213內，而一面緊貼著側壁212，換言之，穿孔211係設置於外延伸部213與側壁212連結處。In the present embodiment, the through holes 211 are formed in the outer extension portion 213. In detail, the through hole 211 may be, for example, a rectangular passage extending through the outer extension portion 213, and the three sides thereof are covered in the outer extension portion 213, and one surface is in close contact with the side wall 212, in other words, the through hole 211 is disposed on the outer extension portion 213 and the side wall. 212 links.
如前所述，在本實施例中，遮蔽蓋體21之四側壁212分別有一外延伸部213，每一外延伸部213皆有穿孔211。又，外延伸部213接觸電路板P之接地線路。如此，藉由將遮蔽蓋體21覆蓋於一安裝在電路板P上的電子元件外部，配合外延伸部213接觸電路板P之接地線路及適當的固定方式，即可提供電磁波遮蔽效果，以防止電磁波干擾影響電子元件的運作。至於，為能達成上述效果，其中，遮蔽蓋體21之材料可例如但不限於為不鏽鋼、馬口鐵、洋白銅等。As described above, in the embodiment, the four side walls 212 of the shielding cover 21 respectively have an outer extending portion 213, and each of the outer extending portions 213 has a through hole 211. Further, the outer extension portion 213 contacts the ground line of the circuit board P. Thus, by covering the shielding cover 21 to the outside of the electronic component mounted on the circuit board P, the external extension 213 is in contact with the grounding line of the circuit board P and an appropriate fixing manner, thereby providing an electromagnetic wave shielding effect to prevent Electromagnetic interference affects the operation of electronic components. As a result, in order to achieve the above effects, the material of the shielding cover 21 may be, for example but not limited to, stainless steel, tinplate, white copper or the like.
卡扣件22分別具有一彈性部221與一固定部222。其中，固定部222提供適當的構型，以透過例如焊接、黏合、鎖固等方式而固設於電路板P。在本實施例中，固定部222係為例如長方形平板，其對應電路板P之一側具有一平面，此平面係用於焊接或黏合於電路板P。當然，基於可固定的條件下，其他例如半圓形、三角形或其他多邊形之板體或片體亦可為固定部222。The fastening members 22 respectively have an elastic portion 221 and a fixing portion 222. The fixing portion 222 is provided with an appropriate configuration to be fixed to the circuit board P by, for example, soldering, bonding, locking, or the like. In the present embodiment, the fixing portion 222 is, for example, a rectangular flat plate having a plane on one side of the corresponding circuit board P for soldering or bonding to the circuit board P. Of course, other plates or sheets such as semi-circular, triangular or other polygons may be the fixing portion 222 based on the fixable conditions.
在本實施例中，彈性部221係為與固定部222連結且兩者間形成90度夾角，是以，彈性部221與電路板P垂直。其中，需要特別強調的是，在此所稱之彈性部221，係指此卡扣件22的一部分，其因具有選定的材料與結構，故於適當外力下會發生形變，而於外力移除後又可再恢復原貌。舉例而言，請參考圖2B所示，彈性部221係由略具厚度之塑膠片材(如圖中標示223之處)以及長條形部分(如圖中標示224之處)所組成，在供使用者以兩手指分別施以擠壓外力的位置間為中空空間，僅在下端另以長條形部分連結。In the present embodiment, the elastic portion 221 is coupled to the fixing portion 222 and forms an angle of 90 degrees therebetween, so that the elastic portion 221 is perpendicular to the circuit board P. It should be particularly emphasized that the elastic portion 221 referred to herein refers to a portion of the snap member 22, which has a selected material and structure, and is deformed under appropriate external force, and is removed by external force. After that, the original appearance can be restored. For example, referring to FIG. 2B, the elastic portion 221 is composed of a plastic sheet having a slight thickness (indicated at 223 in the figure) and a long strip portion (indicated at 224 in the figure). The space for the user to apply the external force by the two fingers is a hollow space, and only the lower end is connected by the elongated portion.
透過上述特性，彈性部221可變形以穿過遮蔽蓋體21上對應之穿孔211，並恢復以固定該遮蔽蓋體21於電路板P。在本實施例中，卡扣件22的數目及設置之位置並不限定，可依實際需要調整，在本實施例中，係對應遮蔽蓋體21之穿孔211數目而以四個卡扣件22為例。特別值得說明的是，為使彈性部221能基於外力擠壓方式穿過穿孔211，彈性部221可具有大於穿孔211之寬度。進一步說明，彈性部221具有二按壓部223，於此係以半圓形為例，按壓部223由一端至另一端間的最長寬度d1 係大於穿孔211之寬度d2 ，使按壓部223可被按壓變形以通過穿孔211。在組裝或拆解時，可將半圓形之按壓部223向內擠壓，使其兩邊之寬度d1 略小於穿孔211之寬度d2 ，以穿過對應之穿孔211，相當方便於組裝或拆解，且不易損壞遮蔽蓋體21。而按壓部223之形狀包括圓形、半圓形、矩形、三角形、楔形、梯型、菱形或環形，並不以此為限，凡能適於施加外力的形狀均可用之。此外，在其他實施例中，彈性部221亦可具有一連接部，其可為具有弧度的條型料件，連接該些按壓部223，除可增加按壓部223的結構強度，避免斷裂，亦可調整按壓部223受力時的形變程度。當然，本實施例之卡扣件22及其各細部結構可以射出方式一體成型。Through the above characteristics, the elastic portion 221 can be deformed to pass through the corresponding through hole 211 of the shielding cover 21 and restored to fix the shielding cover 21 to the circuit board P. In this embodiment, the number of the latching members 22 and the position of the latching member 22 are not limited, and can be adjusted according to actual needs. In the present embodiment, the number of the punching holes 211 corresponding to the shielding cover body 21 is four latching members 22 For example. It is particularly worth mentioning that the elastic portion 221 may have a width larger than the width of the through hole 211 in order to allow the elastic portion 221 to pass through the through hole 211 in an extrusion manner based on an external force. Further, the elastic portion 221 has two pressing portions 223. Here, the semicircular shape is taken as an example. The longest width d 1 of the pressing portion 223 from one end to the other end is greater than the width d 2 of the through hole 211, so that the pressing portion 223 can be It is pressed and deformed to pass through the through hole 211. When assembling or disassembling, the semi-circular pressing portion 223 may be pressed inwardly so that the width d 1 of both sides thereof is slightly smaller than the width d 2 of the through hole 211 to pass through the corresponding through hole 211, which is quite convenient for assembly or It is disassembled and it is not easy to damage the shielding cover 21. The shape of the pressing portion 223 includes a circular shape, a semicircular shape, a rectangular shape, a triangular shape, a wedge shape, a ladder shape, a diamond shape, or a ring shape, and is not limited thereto, and any shape suitable for applying an external force can be used. In addition, in other embodiments, the elastic portion 221 may also have a connecting portion, which may be a strip-shaped material having a curvature, and the pressing portions 223 may be connected, in addition to increasing the structural strength of the pressing portion 223 to avoid breakage. The degree of deformation of the pressing portion 223 when the force is applied can be adjusted. Of course, the snap member 22 of the embodiment and its various detailed structures can be integrally formed in an injection manner.
當然，在彈性部221變形以穿過穿孔211的條件下，本發明並不限制變形的程度及方式。以變形程度而言，變形量大當然有利於彈性部221通過穿孔211，例如變形後之彈性部221之寬度d1 為穿孔211之寬度d2 之三分之二。至於其他變形方式例如壓縮等。Of course, under the condition that the elastic portion 221 is deformed to pass through the through hole 211, the present invention does not limit the degree and manner of deformation. In terms of the degree of deformation, the large amount of deformation is of course advantageous for the elastic portion 221 to pass through the through hole 211. For example, the width d 1 of the elastic portion 221 after deformation is two-thirds of the width d 2 of the through hole 211. As for other deformation methods such as compression and the like.
此外，在本實施例中，遮蔽蓋體21之外延伸部213可具有對應卡扣件22數目之多數個凸起結構214，其可與電路板P形成一容置空間以容置固定部222。如前所述，固定部222對應電路板P之一側可具有一平面，並以該平面焊接或黏合於電路板P，是以，卡扣件22之固定部222較佳係為如圖所示之平板，其不僅有一平面可黏合或焊接於電路板P，而且較適合卡合於凸起結構214與電路板P間形成的容置空間。如此一來，可增加電路板P、固定部222與遮蔽蓋體21之接觸面積，以提升電路板P、固定部222與遮蔽蓋體21之結合穩定性。其中，再次強調的是，固定部222之形體不以平板為限，亦可為錐體或半球體等等，但與電路板P貼合之一側仍以平面為佳。至於，容置空間則對應固定部222之形體設計，以使固定部222能容置與容置空間中，增加其接觸面積，使遮蔽裝置2的定位能更穩固。In addition, in the present embodiment, the outer cover portion 213 of the shielding cover 21 can have a plurality of protruding structures 214 corresponding to the number of the latching members 22, which can form an accommodating space with the circuit board P to accommodate the fixing portion 222. . As described above, the fixing portion 222 may have a flat surface on one side of the circuit board P and be soldered or bonded to the circuit board P in the plane, so that the fixing portion 222 of the latching member 22 is preferably as shown in the figure. The flat panel has a flat surface that can be bonded or soldered to the circuit board P, and is more suitable for being engaged with the accommodating space formed between the protruding structure 214 and the circuit board P. In this way, the contact area between the circuit board P and the fixing portion 222 and the shielding cover 21 can be increased to improve the bonding stability between the circuit board P, the fixing portion 222 and the shielding cover 21. It is emphasized that the shape of the fixing portion 222 is not limited to a flat plate, and may be a cone or a hemisphere, etc., but one side of the circuit board P is preferably a flat surface. The accommodating space is corresponding to the shape of the fixing portion 222, so that the fixing portion 222 can be accommodated in the accommodating space, and the contact area thereof is increased, so that the positioning of the shielding device 2 can be more stable.
圖3A與圖3B分別為本發明第二實施例之一種遮蔽裝置之組合圖與分解圖。請參照圖3A與圖3B所示，在本實施例中，遮蔽裝置3與前一實施例大致相同，遮蔽蓋體31之一側壁312具有一外延伸部313，外延伸部313亦具有多數個凸起結構314。惟不同的是，電路板P具有多數插槽C，且卡扣件32之固定部322插設於對應之該些插槽C。在本實施例中，固定部322係以一平板322a連結一長方柱體322b為例，對應插設於電路板P之插槽C中。而卡扣件32之彈性部321具有二按壓部323，其係與固定部322之平板322a及長方柱體322b一體成型。實際作業時，係將卡扣件32之長方柱體322b利用卡扣、膠黏、焊接等方式插設於電路板P之插槽C，再例如將平板322a焊接固定於電路板P，以增加電路板P與固定部322之接觸面積，以提升電路板P與固定部322之結合穩定性。接著，按壓彈性部321穿過遮蔽蓋體31之穿孔311，即可完成遮蔽裝置3的設置。值得注意的是，在本發明其他實施例中，卡扣件32之固定部322亦可單獨為一柱體，利用插設的方式固定之。3A and 3B are respectively a combined view and an exploded view of a shielding device according to a second embodiment of the present invention. Referring to FIG. 3A and FIG. 3B, in the present embodiment, the shielding device 3 is substantially the same as the previous embodiment. One side wall 312 of the shielding cover 31 has an outer extending portion 313, and the outer extending portion 313 also has a plurality of portions. Raised structure 314. The difference is that the circuit board P has a plurality of slots C, and the fixing portions 322 of the latching members 32 are inserted into the corresponding slots C. In the embodiment, the fixing portion 322 is connected to a rectangular cylinder 322b by a flat plate 322a, and is inserted into the slot C of the circuit board P. The elastic portion 321 of the latching member 32 has two pressing portions 323 which are integrally formed with the flat plate 322a of the fixing portion 322 and the rectangular cylinder 322b. In the actual operation, the rectangular cylinder 322b of the latching member 32 is inserted into the slot C of the circuit board P by means of snapping, gluing, soldering, etc., and the flat plate 322a is soldered and fixed to the circuit board P, for example. The contact area between the circuit board P and the fixing portion 322 is increased to improve the combination stability of the circuit board P and the fixing portion 322. Then, pressing the elastic portion 321 through the through hole 311 of the shielding cover 31 completes the installation of the shielding device 3. It should be noted that in other embodiments of the present invention, the fixing portion 322 of the latching member 32 can also be a single cylinder and fixed by means of insertion.
綜上所述，因依據本發明之一種遮蔽裝置，利用多數卡扣件對應穿過遮蔽蓋體之穿孔，將遮蔽蓋體固定於電路板上。與習知技術相較，本發明不僅易組裝與拆解，且當電路板之形狀或電子元件擺放位置改變，只要調整卡扣件固定於電路板之位置，即可利用卡扣件將遮蔽蓋體組合於電路板上，完成一可量產且易組裝與拆解的遮蔽裝置。In summary, according to the shielding device of the present invention, the shielding cover is fixed to the circuit board by using a plurality of fastening members corresponding to the through holes of the shielding cover. Compared with the prior art, the present invention is not only easy to assemble and disassemble, but when the shape of the circuit board or the position of the electronic component is changed, as long as the position of the latching member is fixed to the circuit board, the latching member can be used for shielding. The cover body is combined on the circuit board to complete a masking device that is mass-produced and easy to assemble and disassemble.
以上所述僅為舉例性，而非為限制性者。任何未脫離本發明之精神與範疇，而對其進行之等效修改或變更，均應包括於後附之申請專利範圍中。The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
