發進出該無線模組mini卡的一無線射頻訊號。 【實施方式】 有關本發明之前述及其他技術内容、特點與功效，在 以下配合參考圖式之兩個較佳實施例的詳細說明中，將可 清楚的呈現。 參閱圖1所示，是本發明無線模組轉接裝置的第一較 佳實施例，本實施例之無線模組轉接裝置1包括一電路基 板11、一 new卡連接器12、一 mini卡連接器13、一天線 單元 14 及一 SIM(Subscriber Identify Module，用戶識別模 組）卡連接器15。 200841537 電路基板11是一印刷電路板，其尺寸大小約為 139mm(長）x47.5mm(寬）。 new卡連接器12設在電路基板11的一側邊，用以與一 主機（例如筆記型電腦）2之一 new卡連接器21電性對接。 new卡連接器12在本實施例中是一 PCI-E規格的連接器（目 前稱做PCI-E卡連接器），其除了具有PCI-E介面外，亦具 備USB介面（USB2.0)，可供傳輸PCI-E訊號或USB訊號。 mini卡連接器13設在電路基板11上靠近中間位置， 並與new卡連接器12電連接。在本實施例中，mini卡連接 器13是一 PCI-E規格的連接器（目前稱做mini PCI-E卡連 接器），它是供無線模組mini卡（或稱mini PCI_E卡）3，例 如前述之3G mini卡、無線網路mini卡及電視選台器（TV-Tuner)mini卡等插置使用，mini卡連接器13的外觀結構雖 然較new卡連接器12小，但其基本的訊號接腳及電氣特性 仍與new卡連接器12相同，所以其與new卡連接器12之 接腳是一對一地電連接。 天線單元14與電路基板11電連接，用以收發無線射頻 訊號，且天線單元14透過電路基板11與插設在mini卡連 接器13上的無線模組mini卡3電連接，以收發進出無線模 組mini卡3的無線射頻訊號。 在本實施例中，天線單元14是可替換地組設在電路基 板11上，以配合無線模組mini卡3使用。因為不同的無線 模組mini卡3所使用的天線頻段及天線數量不同，所以， 為配合不同的無線模組mini卡3，在此所謂之天線單元14 200841537 可能是代表單一天線或複數天線，端視mini卡連接器13所 插置之無線模組mini卡3而定。為了方便替換不同天線單 元，本實施例之天線單元14是以外接方式固定在電路基板 11上，例如在電路基板11的一側邊以及天線單元14的末 端分別設置可相螺接的一螺鎖接頭110、141，使天線單元 14可螺設在電路基板11上，並且設在電路基板11上的螺 鎖接頭110更朝mini卡連接器13方向延伸一導線111，並 於導線111末端設一導接點112。 因此，當無線模組mini卡3插設在mini卡連接器13 上時，由於無線模組mini卡3是平躺在電路基板11上，所 以設於無線模組mini卡3底面的一接點（圖未示）就會與電 路基板11上的導接點112電性導接，而使天線單元14與無 線模組mini卡3之間可以傳送無線射頻訊號。 SIM卡連接器15設在電路基板11上，與mini卡連接 器13電連接，並供一 SIM卡4插置，藉此，SIM卡4上的 資料可透過SIM卡連接器15及mini卡連接器13傳送給插 置在mini卡連接器13上的無線模組mini卡3。 因此，當mini卡連接器13上插置之無線模組mini卡 是一 3G mini卡，且一與該3G mini卡搭配之天線單元14 螺設在電路基板11上，並且SIM卡連接器15插置使用者 之一 SIM卡4時，無線模組轉接裝置1即構成一可收發3G 訊號之3G行動通訊裝置，所以，將new卡（PCI-E)連接器 12插置在主機2(例如筆記型電腦）預設的PCI-E連接器插槽 ，筆記型電腦即可透過無線模組轉接裝置1收發3G訊號（ 10 200841537 κ 例如行動電話語音、多媒體影音訊號、影音電話等）。 • 而當mini卡連接器13上插置之無線模組mini卡是一 無線網路mini卡，且一與該無線網路mini卡配合之天線單 元14螺設在電路基板11上時（此時，SIM卡連接器15無作 用），無線模組轉接裝置1即構成一無線網路模組，所以 new卡連接器12插置在筆記型電腦之預設的PCI-E連接器 插槽時，筆記型電腦即可透過無線模組轉接裝置1無線上 網而瀏覽網頁資訊、收發電子郵件等。 再者，當mini卡連接器13上插置之無線模組mini卡 是一電視選台器（TV-Tuner)mini卡，且一與該電視選台器 (TV-Tuner)mini卡配合之天線單元14螺設在電路基板11上 時，無線模組轉接裝置1即構成一電視頻道選台器裝置， 因此，new卡連接器12插置在筆記型電腦之預設的PCI-E 連接器插槽時，筆記型電腦即可透過無線模組轉接裝置1 收看電視頻道節目。 此外，本實施例之無線模組轉接裝置1更包括一判斷 i 電路16，其連接在new卡連接器12與mini卡連接器13之 間，並根據new卡連接器12與mini卡連接器13之間連接 的一時脈要求接腳CLKREQ，判斷插置在mini卡連接器13 上的無線模組mini卡的使用介面是PCI-E介面還是USB介 面，並送出一判斷訊號（CPUSB或CPPE)給new卡連接器 12，以透過new卡連接器12送給主機2。 判斷電路16之細部電路如圖2所示，亦即，當無線模 組mini卡使用介面是PCI-E介面時，無線模組mini卡3會 11 200841537 透過時脈要求接腳CLKREQ會送出一 CLKREQ訊號給new 卡連接器12(送至主機2)，此時，判斷電路16經過内部邏 輯電路判斷後，送出一 CPUSB訊號。而當無線模組mini卡 使用介面是USB介面時，無線模組mini卡3則不會送出 CLKREQ訊號給new卡連接器12(送至主機2)，判斷電路 16經過内部邏輯電路判斷後，送出一 CPPE訊號。 再參見圖3所示，是本發明無線模組轉接裝置的第二 較佳實施例，本實施例與第一實施例主要不同處在於，本 實施例之天線單元54是内建在無線模組轉接裝置5的電路 基板51上，並由天線單元54延伸一導線541至鄰近mini 卡連接器53處，且於導線541末端設一導接點542。且本 實施例之天線單元54是一多頻段天線，亦即當無線模組 mini卡3插置在mini卡連接器53上時，設於無線模組 mini卡3底面的一接點（圖未示）會與電路基板51上的導接 點542電性連接，且無線模組mini卡3於傳送訊號時，會 自動根據其使用頻段，選擇天線單元54上的某一或某幾個 操作頻段來傳送訊號（無線射頻訊號）。 綜上所述，上述實施例藉由在無線模組轉接裝置之電 路基板11(51)上設置相互間適當電性連接之new卡連接器 12(52)、mini卡連接器13(52)及SIM卡連接器，可供不同 的無線模組mini卡及相配合之SIM卡組接，並透過外接或 内建方式搭配適當的天線單元15(55)，讓無線模組轉接裝置 1(5)可構成不同功能的無線模組，而方便使用者彈性運用， 而且適用於現有廣泛預設有PCI-E連接器（插槽）但未内建 12 200841537 #卡連接杰的筆§己型電腦或桌上型電滕。此外，由於無

The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. As shown in FIG. 1 , it is a first preferred embodiment of the wireless module switching device of the present invention. The wireless module switching device 1 of the present embodiment includes a circuit substrate 11 , a new card connector 12 , and a mini card . The connector 13, an antenna unit 14, and a SIM (Subscriber Identify Module) card connector 15. 200841537 The circuit substrate 11 is a printed circuit board having a size of about 139 mm (length) x 47.5 mm (width). The new card connector 12 is disposed on one side of the circuit board 11 for electrically interfacing with a new card connector 21 of a host (e.g., notebook computer) 2. In this embodiment, the new card connector 12 is a PCI-E type connector (currently referred to as a PCI-E card connector), which has a USB interface (USB2.0) in addition to the PCI-E interface. Can be used to transmit PCI-E signals or USB signals. The mini card connector 13 is disposed on the circuit substrate 11 near the intermediate position and is electrically connected to the new card connector 12. In this embodiment, the mini card connector 13 is a PCI-E type connector (currently referred to as a mini PCI-E card connector), which is a wireless module mini card (or mini PCI_E card) 3, For example, the aforementioned 3G mini card, wireless network mini card and TV tuner (TV-Tuner) mini card are inserted, and the appearance structure of the mini card connector 13 is smaller than that of the new card connector 12, but its basic The signal pins and electrical characteristics are still the same as the new card connector 12, so that they are electrically connected one-to-one with the pins of the new card connector 12. The antenna unit 14 is electrically connected to the circuit board 11 for transmitting and receiving wireless RF signals, and the antenna unit 14 is electrically connected to the wireless module mini card 3 inserted in the mini card connector 13 through the circuit board 11 to transmit and receive the wireless module. Group radio card 3 radio frequency signal. In the present embodiment, the antenna unit 14 is alternatively assembled on the circuit board 11 for use with the wireless module mini card 3. Because the antenna band and the number of antennas used by different wireless module mini cards 3 are different, so to match different wireless module mini cards 3, the so-called antenna unit 14 200841537 may represent a single antenna or a plurality of antennas. It depends on the wireless module mini card 3 inserted in the mini card connector 13. In order to facilitate the replacement of the different antenna units, the antenna unit 14 of the present embodiment is fixed to the circuit substrate 11 in an external manner.

In addition, the wireless module switching device 1 of the present embodiment further includes a determining i circuit 16 connected between the new card connector 12 and the mini card connector 13, and according to the new card connector 12 and the mini card connector. A clock connection between the 13 requests a pin CLKREQ, and determines whether the wireless module of the mini card connector 13 is used in the PCI-E interface or the USB interface, and sends a judgment signal (CPUSB or CPPE). The new card connector 12 is supplied to the host 2 via the new card connector 12. The detailed circuit of the judging circuit 16 is as shown in FIG. 2, that is, when the wireless module mini card use interface is a PCI-E interface, the wireless module mini card 3 will 11 200841537 through the clock request pin CLKREQ will send a CLKREQ The signal is sent to the new card connector 12 (sent to the host 2). At this time, the judging circuit 16 sends a CPUSB signal after being judged by the internal logic circuit. When the wireless module mini card use interface is a USB interface, the wireless module mini card 3 will not send the CLKREQ signal to the new card connector 12 (sent to the host 2), and the judgment circuit 16 is sent after the internal logic circuit judges A CPPE signal. Referring to FIG. 3 again, it is a second preferred embodiment of the wireless module switching device of the present invention. The main difference between this embodiment and the first embodiment is that the antenna unit 54 of the embodiment is built in the wireless module. On the circuit substrate 51 of the group switching device 5, a wire 541 extends from the antenna unit 54 to the adjacent mini-card connector 53, and a conductive contact 542 is disposed at the end of the wire 541.
