Description

Electrical connection device

本揭露係關於一種電連接裝置。The present disclosure relates to an electrical connection device.

電連接裝置廣泛用於各種電子資訊產品中，用以連接不同的傳輸端以傳遞訊號。由於數據傳輸量日益增長及複雜化，電連接裝置需要提高傳輸頻率以及具備更多密集分布的傳輸端子才能滿足大量數據傳輸的需求。然而高頻傳輸容易面臨密集端子之間訊號的耦合串擾(cross talk)的問題，另外，於該電連接裝置與外部傳輸端(例如一主機板)藉由例如表面黏著(SMT, Surface-mount technology)等技術結合時，多數端子亦容易產生共面性不良的問題。中國專利申請號201510514802.9號（中國專利公開號：CN106469863A）揭示一電連接裝置，其利用插座單元中之複數個訊號端子以連接不同的傳輸端，並利用間隔於該複數個訊號端子間的接地端子以降低訊號端子之間的串擾問題。惟，當該電連接裝置具有複數個插座單元時，該複數個插座單元將互相堆疊，則距離所要連接的傳輸端較遠的插座單元將需要較長的訊號端子以傳輸訊號，對於該較長的訊號端子而言，間隔於其中的接地端子的降低串擾效果有限。此外，該中國專利中的端子與電路板之結合是藉由端子的針腳狀尾部插入電路板上之穿孔而結合，穿孔將破壞電路板並使電路板設計的彈性與自由度降低。如欲避免電路板穿孔而將端子與電路板之結合改成藉由例如表面黏著技術結合時，則複數個端子將容易產生共面性問題，較難將複數個端子共面且確實地連接到電路板上正確位置。上文之「先前技術」說明僅係提供背景技術，並未承認上文之「先前技術」說明揭示本揭露之標的，不構成本揭露之先前技術，且上文之「先前技術」之任何說明均不應作為本案之任一部分。Electrical connection devices are widely used in various electronic information products to connect different transmission terminals to transmit signals. Due to the increasing and complicated data transmission volume, electrical connection devices need to increase the transmission frequency and have more densely distributed transmission terminals to meet the demand for a large amount of data transmission. However, high-frequency transmission is prone to the problem of coupling cross talk of signals between dense terminals. In addition, the electrical connection device and the external transmission end (for example, a motherboard) are adhered by, for example, surface adhesion (SMT, Surface-mount technology). When a technology is combined, many terminals are prone to problems of poor coplanarity. Chinese Patent Application No. 201510514802.9 (Chinese Patent Publication No.: CN106469863A) discloses an electrical connection device that utilizes a plurality of signal terminals in a socket unit to connect different transmission terminals and utilizes a ground terminal spaced between the plurality of signal terminals To reduce crosstalk between signal terminals. However, when the electrical connection device has a plurality of socket units, the plurality of socket units will be stacked on each other, and the socket unit farther from the transmission end to be connected will require a longer signal terminal to transmit signals, which is longer. For the signal terminals, the crosstalk effect of the ground terminals spaced therein is limited. In addition, the combination of the terminal and the circuit board in the Chinese patent is combined by the insertion of the pin-shaped tail of the terminal into the perforation on the circuit board, which will damage the circuit board and reduce the flexibility and freedom of the circuit board design. If the circuit board is to be perforated and the combination of the terminal and the circuit board is changed to be combined by, for example, surface adhesion technology, a plurality of terminals will easily cause coplanarity problems, and it is difficult to connect a plurality of terminals coplanarly and surely to The correct position on the board. The above description of the "prior art" is merely an indication of the prior art and does not constitute a prior art description of the disclosure, and does not constitute a prior art of the disclosure, and any description of the "previous technique" above. Neither should be part of this case.

alignment)，使安裝部320與基板800能更精確地組合。在一些實施例中，基板800可為硬性電路板。兩固定件700位於第三方向D3上，用以固定基座200、蓋體600以及基板800之組合。各固定件700包括兩端部710。基座200更包括位於第三方向D3上之兩第一插孔250。蓋體600更包括位於第三方向D3上之兩第二插孔650。基板800在第三方向D3上之兩端各更包括兩第三插孔850。各固定件700之兩端部710分別穿過第一插孔250與第二插孔650，再分別插入且固定於兩第三插孔850，藉此加強蓋體600與基座200結合的強度，並將蓋體600與基座200一起安裝固定到基板800上。在其他實施例中，各固定件700之兩端部710插入第三插孔850後可再藉由焊接等技術加強固定。圖8A、8B、8C係本揭露之不同實施例之電連接裝置之連接器與柔性電路板之組合的側視圖。參照圖8A，其所示之柔性電路板300為圖1至圖7之實施例之柔性電路板300。詳細來說，第一對接部310與第二對接部330皆位於柔性電路板300之一第一端351，安裝部320位於柔性電路板300之相對於第一端351之一第二端352，連接部350連接第一對接部310與安裝部320且用以圍繞包覆基座200(參照圖1至圖7)。參照圖8B，其顯示在另一實施例之柔性電路板300A中，第一對接部310與第二對接部330皆位於柔性電路板300之一第一端351，安裝部320位於柔性電路板300之相對於第一端351之一第二端352。在本實施例中，柔性電路板300不包括圖8A顯示的圍繞包覆基座200之連接部350，安裝部320則是先連接到第二對接部330再連接到第一對接部310，且該柔性電路板300A之側視為一L型。參照圖8C，其顯示在另一實施例之柔性電路板300B中，第一對接部310位於柔性電路板300B之第一端351，第二對接部330位於柔性電路板300B之第二端352，安裝部320則配置於第一對接部310與第二對接部330之間，並具有用以圍繞包覆基座200且連接第一對接部310與安裝部320之連接部350。相較於柔性電路板300A或柔性電路板300B，柔性電路板300由於不具備直接連接第二對接部330與安裝部320之L型構造，其在第二方向D2上之高度可較低，具備整體結構可較小之優點。另，在柔性電路板300B之設計中，第一對接部310至安裝部320的佈線與第二對接部330至安裝部320的佈線由於是走不同方向不會重疊，因此可設計在柔性電路板300B中的同一層中，亦即，連接第一連接器400之訊號至安裝部320之第一導電跡線與連接第二連接器500之訊號至安裝部320之第二導電跡線可配置於柔性電路板300B中的同一層。相較之下，柔性電路板300或柔性電路板300A中，由於第一對接部310至安裝部320的佈線與第二對接部330至安裝部320的佈線會重疊，因此需要比柔性電路板300B多一層的電路板。圖11係本揭露之一實施例之電連接裝置100之部分立體示意圖。圖12係圖11之電連接裝置100之部分分解立體示意圖。參照圖11及圖12，此實施例之電連接裝置100中，柔性電路板300更包括兩導光管900，用以導引並集中安裝於柔性電路板300上之發光二極體元件(未圖示)所發出的代表訊號傳輸狀態的光，蓋體600更包括兩導光孔901，當蓋體600與柔性電路板300、基座200等組合時，兩導光管900將穿過兩導光孔901而外露，進而可觀察兩導光管900的發光狀態以偵測電連接器是否在工作中。圖13係本揭露之一實施例之柔性電路板300展開狀態之俯視示意圖。參照圖13，複數個第一焊墊314與複數個第一錫球324是藉由複數個第一導電跡線380相連接，複數個第二焊墊334與複數個第二錫球326是藉由複數個第二導電跡線390相連接。更具體來說，各第一導電跡線380具有一第一線本體3801、一第一表面焊接端3802以及一第一轉接焊接端3803。第一線本體3801配置於柔性電路板300中，第一表面焊接端3802連接第一焊墊314，第一轉接焊接端3803連接第一錫球324，藉此達成各第一焊墊314與各第一錫球324之連接。同樣地，各第二導電跡線390具有一第二線本體3901、一第二表面焊接端3902以及一第二轉接焊接端3903。第二線本體3901配置於柔性電路板300中，第二表面焊接端3902連接第二焊墊334，第二轉接焊接端3903連接第二錫球326，藉此達成各第二焊墊334與各第二錫球326之連接。請注意，本實施例之圖示中，第一焊墊314、第二焊墊334、第一錫球324以及第二錫球326所標號之數量及位置僅為示例，其相對的連接關係可跟據實際需求配置，本揭露並不限於此，例如在其他實施例中，第一焊墊314也可能連接至本實施例中標示324之錫球。在本揭露之一實施例中，電連接裝置100之第一連接器400之第一端子440與第二連接器500之第二端子540並無直接與基板800相連接，而是藉由柔性電路板300之第一對接部310、第二對接部330、第一與第二導電跡線以及安裝部與基板800相連接。相較於傳統利用接地端子以降低訊號端子間串擾的作法，在本揭露的該實施例中，由於柔性電路板300中固有接地層可提供較好的接地參考以及屏蔽，以更大範圍地吸收第一與第二導電跡線傳輸訊號時所發出的例如電磁波等干擾，因此可較佳地降低第一與第二導電跡線之間的串擾。此外，利用柔性電路板300以降低串擾的效果不受連接器的堆疊數目影響，因此電連接裝置100之設計可更有彈性，例如可進一步擴充以包含更多連接器。在本揭露之一實施例中，電連接裝置100之柔性電路板300是藉由複數個第一錫球324以及第二錫球326與基板800做連接。相較於傳統利用端子直接與電路板連接的做法，該實施例中複數個第一錫球324以及第二錫球326可在藉由例如表面黏著技術與基板800連接時提供較好的共面性，使複數個第一錫球324以及第二錫球326能確實地安裝到基板800上之正確位置。在本揭露之一實施例中，電連接裝置100之基座200、蓋體600以及基板800是藉由固定件700以強化該組合之固定。前述內容概述一些實施方式的特徵，因而熟知此技藝的人士可更加理解本申請案揭示內容的各方面。熟知此技藝的人士應理解可輕易使用本申請案揭示內容作為基礎，經配置設計或修飾其他製程與結構而實現與本申請案所述的實施方式具有相同目的與/或達到相同優點。熟知此技藝的人士亦應理解此均等架構並不脫離本申請案揭示內容的精神與範圍，以及熟知此技藝的人士可進行各種變化、取代與替換，而不脫離本申請案揭示內容的精神與範圍。The

In this embodiment, the base body 220, the first support portion 244, and the second support portion 242 are independent of each other, and thus may each comprise different materials. For example, the base body 220 includes a plasticized material, and the first support portion 244 Or the second support portion 242 contains a metal material. In some embodiments, the first support portion 244 and the second support portion 242 can be integrated.
