Description
本創作關於一種天線裝置及無線通訊裝置,尤指一種具有結構簡單且提供可靠下地作用之天線接地結構的天線裝置及無線通訊裝置。The present invention relates to an antenna device and a wireless communication device, and more particularly to an antenna device and a wireless communication device having an antenna grounding structure which is simple in structure and provides reliable grounding action.
在無線通訊裝置中,用來發射接收無線電波以傳遞交換無線電資料訊號之天線,無疑是最重要的元件之一。應用於用戶端裝置(Customer Premise Equipment,CPE)中的CPE天線通常需設置一反射板以增加天線的效能,並提昇無線通訊裝置之主板上晶片的散熱性能。天線裝置以同軸電纜與主板連接,同軸電纜之內芯作為信號線,而同軸電纜之外層則作為接地線,與反射板相連。In wireless communication devices, an antenna for transmitting and receiving radio waves to transmit radio data signals is undoubtedly one of the most important components. A CPE antenna used in a Customer Premise Equipment (CPE) usually needs to be provided with a reflector to increase the performance of the antenna and improve the heat dissipation performance of the chip on the motherboard of the wireless communication device. The antenna device is connected to the main board by a coaxial cable, and the inner core of the coaxial cable is used as a signal line, and the outer layer of the coaxial cable is used as a ground line and connected to the reflector.
在習知技術中,CPE天線的反射板與同軸電纜相接之接地結構有兩種。第一種結構運用特製化的同軸電纜,將同軸電纜上刻製螺紋,用以接合設置於反射板上的螺帽,使同軸電纜可鎖固於反射板上。然而,由於需要特製的同軸電纜,因此價格較昂貴。另一種習知技術係將反射板鉚接銅鉚柱,並以焊接的方式將同軸電纜與反射板連接。然而,由於反射板上的金屬散熱快,易造成焊接不良或焊點不美觀的問題,因此需較高的焊接技術。此外,銅鉚柱之成本相對較高亦為此種習知接地結構的缺點。In the prior art, there are two kinds of grounding structures in which the reflector of the CPE antenna is connected to the coaxial cable. The first structure uses a special coaxial cable to thread the coaxial cable to engage the nut disposed on the reflector so that the coaxial cable can be locked to the reflector. However, due to the need for a special coaxial cable, it is more expensive. Another conventional technique is to rive the reflector to the copper stud and to solder the coaxial cable to the reflector. However, due to the rapid heat dissipation of the metal on the reflector, it is easy to cause poor soldering or unattractive solder joints, so high soldering techniques are required. In addition, the relatively high cost of the copper studs is a disadvantage of such conventional grounding structures.
因此,如何設計符合無線通訊裝置需求的天線接地結構,同時兼 顧美觀及降低成本,已成為業界所努力的目標之一。Therefore, how to design an antenna grounding structure that meets the requirements of wireless communication devices, and Considering beauty and reducing costs has become one of the goals of the industry.

詳細來說,請配合參考第2圖至第6圖,第2圖為本創作實施例之一天線接地結構組裝前的立體圖,第3圖為天線接地結構組裝前的側面剖視圖,第4圖為第2圖中的天線接地結構組裝後的側面剖視圖,第5圖為第4圖中的天線接地結構藉由一沖頭沖壓時的側面剖視圖,而第6圖為第4圖中的天線接地結構沖壓完成後的立體圖。首先,如第2圖及第3圖所示,本創作實施例係在一金屬板200上製作一翻邊孔204,使翻邊孔204於金屬板200之表面延伸出一翻邊206,其中翻邊孔204之內徑可稍大於一同軸電纜 202之外徑(例如比同軸電纜202之外徑大0.03 mm~0.05mm)。接著,如第4圖所示,將同軸電纜202穿設於翻邊孔204中,同軸電纜202之一設置高度H視金屬板200與一天線的距離而定,可使用一治具定義,但不限於此。然後,如第5圖所示,提供一沖頭DR,將沖頭DR套入同軸電纜202之上端並對沖頭DR施以一外力F,使沖頭DR往金屬板200之一垂直方向沖壓(如第5圖中的箭頭所指示的方向)。其中,沖頭DR之一內側壁具有向外擴展之一斜邊2080,當沖頭DR沖壓翻邊孔204時,斜邊2080擠壓具金屬材質的翻邊206,使翻邊206以緊配的方式夾持住同軸電纜202,進而使同軸電纜202與金屬板200電性連接。由於沖頭DR之內側壁具有向外擴展之斜邊2080,使得沖壓完成後翻邊206之一外緣2060受到擠壓變形而形成一斜面。最後,移走沖頭DR,完成如第6圖所示之天線接地結構。In detail, please refer to FIG. 2 to FIG. 6 together. FIG. 2 is a perspective view of the antenna grounding structure before assembly of the present embodiment, and FIG. 3 is a side cross-sectional view of the antenna grounding structure before assembly, and FIG. FIG. 5 is a side cross-sectional view of the antenna grounding structure assembled in FIG. 2, and FIG. 5 is a side cross-sectional view of the antenna grounding structure in FIG. 4 when punched by a punch, and FIG. 6 is an antenna grounding structure in FIG. A perspective view of the finished stamping. First, as shown in FIG. 2 and FIG. 3, in the present embodiment, a flange hole 204 is formed on a metal plate 200, so that the flange hole 204 extends a flange 206 on the surface of the metal plate 200, wherein The inner diameter of the flange hole 204 can be slightly larger than a coaxial cable The outer diameter of 202 (e.g., 0.03 mm to 0.05 mm larger than the outer diameter of the coaxial cable 202). Next, as shown in FIG. 4, the coaxial cable 202 is inserted into the flange hole 204. The height H of one of the coaxial cables 202 depends on the distance between the metal plate 200 and an antenna, and can be defined by using a fixture. Not limited to this. Then, as shown in Fig. 5, a punch DR is provided, the punch DR is fitted over the upper end of the coaxial cable 202, and an external force F is applied to the punch DR to punch the punch DR in one direction perpendicular to the metal plate 200 ( As indicated by the arrow in Figure 5). The inner side wall of one of the punches DR has an outwardly extending beveled edge 2080. When the punch DR punches the flanged hole 204, the beveled edge 2080 presses the flange 160 of the metal material to make the flange 206 tightly match. The coaxial cable 202 is clamped to electrically connect the coaxial cable 202 to the metal plate 200. Since the inner side wall of the punch DR has an outwardly extending beveled edge 2080, one of the outer edges 2060 of the flange 206 is subjected to extrusion deformation to form a slope. Finally, the punch DR is removed to complete the antenna ground structure as shown in FIG.
因此,相較於習知技術中之天線接地結構需在同軸電纜上刻製螺紋以鎖固同軸電纜與金屬板,或需在反射板鉚接銅鉚柱並以焊接的方式固接同軸電纜與金屬板,本創作不需在同軸電纜及金屬板上額外增設零件,且製作方法簡單,因此可降低生產成本。此外,亦可使用模具以實現批量生產,進而有效提高生產效率。Therefore, compared with the antenna grounding structure in the prior art, the coaxial cable needs to be threaded to lock the coaxial cable and the metal plate, or the copper stud is riveted on the reflector and the coaxial cable and the metal are fixed by welding. Board, this creation does not need to add additional parts on the coaxial cable and metal plate, and the production method is simple, so the production cost can be reduced. In addition, molds can also be used to achieve mass production, thereby effectively increasing production efficiency.
需注意的是,本創作之天線接地結構係利用金屬板上的翻邊以緊配的方式夾持住同軸電纜,進而使同軸電纜與金屬板電性連接,本領域具通常知識者當可據以做不同之變化,而不限於此。舉例來說,為了方便製作翻邊孔並考慮天線接地結構及其製程特性(如金屬板之硬度應小於沖頭之硬度以實施沖壓製程、金屬板需有較佳的延展性及適當的硬度,使其沖壓後可變形夾緊同軸電纜但不至於斷裂、金屬板的導電性及導熱性需符合應用需求等等),在金屬板上係較佳地以金屬鋁板所製成,但不限於此。其他金屬材質如鋁合金板材或銅合金板材等亦可用來製作金屬板,只要該金屬材質可方便製 作翻邊孔並符合天線接地結構及其製程特性的考量即可。其他如金屬板之厚度、翻邊之大小、角度等亦未有所限,只要經過流程10後翻邊可夾緊同軸電纜即可。It should be noted that the antenna grounding structure of the present invention uses the flange on the metal plate to clamp the coaxial cable in a tightly fitting manner, thereby electrically connecting the coaxial cable to the metal plate, and the person having ordinary knowledge in the field can To make different changes, not limited to this. For example, in order to facilitate the fabrication of the flanged hole and consider the antenna grounding structure and its process characteristics (such as the hardness of the metal plate should be less than the hardness of the punch to carry out the stamping process, the metal plate needs to have better ductility and appropriate hardness, The stamped and deformable clamping coaxial cable is not deformed, the conductivity and thermal conductivity of the metal plate are required to meet the application requirements, etc., and the metal plate is preferably made of a metal aluminum plate, but is not limited thereto. . Other metal materials such as aluminum alloy plates or copper alloy plates can also be used to make metal plates, as long as the metal material can be easily manufactured. It can be considered as a flanged hole and conforms to the antenna grounding structure and its process characteristics. Others such as the thickness of the metal plate, the size of the flange, the angle, etc. are not limited, as long as the process can be clamped after the process 10 can be clamped.
另外,本創作之天線接地結構可用於無線通訊裝置中。請參考第7圖,第7圖為本創作實施例之一無線通訊裝置70之側面剖視圖。無線通訊裝置70包含有一主板730及一天線裝置72。主板730可為印刷電路板,如樹脂銅箔基板等導電基板,其上包含有一射頻電路,用來產生射頻訊號。天線裝置72包含有一天線720、一金屬板700以及一同軸電纜702。包含有一輻射部及一饋入部722,用來發射及接收射頻訊號。金屬板700設置於天線720之下方,具有一翻邊孔704,用來電性連接天線裝置72之一系統接地件。同軸電纜702之一內芯708電性連接饋入部722及射頻電路之一輸出端,用來傳送射頻訊號,而同軸電纜702之一外層710電性連接至系統接地件,以提供一接地路徑。同軸電纜702係透過流程10以利用金屬板700上之一翻邊706夾持於金屬板700上,進而使同軸電纜702之外層710與金屬板700電性連接。In addition, the antenna ground structure of the present invention can be used in a wireless communication device. Please refer to FIG. 7. FIG. 7 is a side cross-sectional view of the wireless communication device 70 of the present embodiment. The wireless communication device 70 includes a main board 730 and an antenna device 72. The main board 730 can be a printed circuit board, such as a conductive substrate such as a resin copper foil substrate, and includes a radio frequency circuit for generating an RF signal. The antenna device 72 includes an antenna 720, a metal plate 700, and a coaxial cable 702. A radiating portion and a feeding portion 722 are included for transmitting and receiving radio frequency signals. The metal plate 700 is disposed under the antenna 720 and has a flange hole 704 for electrically connecting one of the system grounding members of the antenna device 72. The inner core 708 of the coaxial cable 702 is electrically connected to the input portion of the feeding portion 722 and the RF circuit for transmitting the RF signal, and the outer layer 710 of the coaxial cable 702 is electrically connected to the system grounding member to provide a grounding path. The coaxial cable 702 is passed through the process 10 to be clamped to the metal plate 700 by using a flange 706 on the metal plate 700, thereby electrically connecting the outer layer 710 of the coaxial cable 702 and the metal plate 700.
值得注意的是,在無線通訊裝置70中,天線720可為一指向性天線(Directional Antenna),如應用於室外用戶端裝置(Customer Premise Equipment,CPE)中的CPE天線等,而不限於此。此時,金屬板700可作為天線720之一反射板,以增加天線720的增益(gain)、降低其他電磁波的干擾或將射頻訊號導向一特定方向等等。此外,金屬板700亦可作為主板730之一散熱板,以增加無線通訊裝置70之性能。在此情形下,在金屬板700與主板730之間另可設置一導熱元件,以增加主板730至金屬板700之熱傳導途徑,此皆應屬本創作之適當變化。It should be noted that in the wireless communication device 70, the antenna 720 can be a Directional Antenna, such as a CPE antenna used in an Outdoor Customer Premise Equipment (CPE), and is not limited thereto. At this time, the metal plate 700 can serve as a reflection plate of the antenna 720 to increase the gain of the antenna 720, reduce the interference of other electromagnetic waves, or direct the RF signal to a specific direction, and the like. In addition, the metal plate 700 can also serve as a heat sink for the motherboard 730 to increase the performance of the wireless communication device 70. In this case, a heat conducting element may be disposed between the metal plate 700 and the main board 730 to increase the heat conduction path of the main board 730 to the metal board 700, which should be appropriately changed in the present creation.
綜上所述,在習知技術中,金屬板與同軸電纜相接之天線接地結構價格較高,且可能因焊接不良而接地不確實,或有焊點不美觀的問題。相較之下,本創作之天線接地結構及其天線裝置及無線通訊裝置可透過金屬板上的翻邊以緊配的方式夾持住同軸電纜,進而使同軸電纜與金屬板電性連接。如此一來,製作方法簡單且不需額外增設零件,因而可降低生產成本。此外,亦可使用模具以實現批量生產,進而有效提高生產效率。In summary, in the prior art, the antenna grounding structure in which the metal plate and the coaxial cable are connected is expensive, and the grounding may be unreliable due to poor soldering, or there may be a problem that the solder joint is not beautiful. In contrast, the antenna grounding structure of the present invention, the antenna device thereof and the wireless communication device can hold the coaxial cable in a tight manner through the flange on the metal plate, thereby electrically connecting the coaxial cable and the metal plate. In this way, the production method is simple and no additional parts are required, so that the production cost can be reduced. In addition, molds can also be used to achieve mass production, thereby effectively increasing production efficiency.
