200816882 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種具有以可重疊且在與重疊方向垂直 方向上相對移動之方式而配置的二個基板，使用同軸電纜 而電氣接續此等基板之同軸電纜接續構造，使用於此構造 之同軸電纜線束及具備前述同軸電纜接續構造之攜帶式終 端機者。 【先前技術】 例如，行動電話之情形，係以可彼此滑動而重疊之二個 框體構成行動電話，並按照行動電話之使用狀況，使此等 二個框體滑動，而可伸長或縮短行動電話之長度。 上述二個框體中設有排列了用於實現各個功能之各種 電路及元件的基板，並設有用於電氣接續此等基板之配線 構件。收納於兩個框體之各基板，爲了因應各框體之動作 而彼此滑動，電氣接續此等基板之配線構件通常使用可彎 曲之軟式基板（FPC)。專利文獻1中揭示有使用此種軟式 基板之一例，如第19圖所示，係以軟式印刷基板104(FPC) 接續設於下側之基板100的連接器101，與設於上側之電路 模組102的連接器103。 已知一種考慮確保低電阻接地導體與EMI對策，係將 FPC之一方之面側的槪略全面作爲接地導體層之全面接地 構造者。但是，此等全面接地之FPC無法確保因應基板滑 動之彎曲性，而可能在彎曲部分發生裂痕而斷線。 爲了解決上述全面接地之FPC的彎曲性方面之問題，如 專利文獻1中揭示有：在彎曲部中局部刪除接地部，且在 200816882 彎曲部之背側’以不與信號線對峙之方式而配置複數條接 地線的結構。 [專利文獻1]日本公開專利：日本特開2004-88020號公 報 【發明內容】 (發明所欲解決之問題） 如上述，FPC在接地之電氣特性方面固然可全面接地， 但是，如此則有彎曲性之問題，此外，排除全面接地情況 下，無論如何都有電氣特性（阻抗匹配及EMI特性）惡化 的問題。 如專利文獻1，在彎曲部之背面配置接地線，以信號線 與接地線不對峙之方式而配置之方法，因資料之高速傳送 及高密度化，而信號線數量增加時，FPC之寬度擴大。連 同在二個基板間須確保FPC滑動用的空間變大。此與機器 之小型化相違背。 本發明之目的爲提供在電氣接續以可重疊且在與重疊 方向垂直方向上相對移動之方式而配置之二個基板間的接 續構造中，彎曲性方面之機械可靠性、減少機器內用於滑 動所佔之空間、阻抗匹配及EMI特性方面之電氣特性優異 的同軸電纜接續構造、使用於此構造之同軸電纜線束及攜 帶式終端機。 (解決問題之手段） 可達成前述目的之本發明的同軸電纜接續構造，係以包 含至少在一處集束之複數條同軸電纜而構成的同軸電纜線 束，接續上下重疊配置而滑動之二個基板間之同軸電纜接 200816882 續構造’其特徵爲：以前述同軸電纜線束整體成爲u字狀 之方式接續。 用於本發明之同軸電纜線束亦可全部並非同軸電纜，而 可包含不具外部導體之絕緣電線。本發明由於信號線中可 使用同軸電纜，因此阻抗匹配及EMI特性方面之電氣特性 良好。不具外部導體之絕緣電線可使用於饋電線及接地 線。集束此等線時，無須與同軸電纜作區別。 使兩基板滑動時，同軸電纜線束之彎曲成U字狀的部分 ^ 移動，而追隨基板之移動。此時同軸電纜線束爲了滑動而 需要之空間（滑動空間），其高度係同軸電纜線束之厚度， 其寬度成爲U字之寬度。將同軸電纜線束形成其剖面橢圓 之扁平形狀時，其厚度可變薄。藉此，可縮小上下基板之 間隙。此外，U字之寬度可比基板之寬度大幅縮小。因此， 可縮小基板間之間隙，且確保同軸電纜線束充分之滑動空 間。 本發明之同軸電纜接續構造，宜在前述同軸電纜線束之 I 至少一部分的終端安裝有共通之連接器。 如此構成之同軸電纜接續構造中，由於在同軸電纜線束 之終端安裝有連接器，因此可輕易進行與基板之連接。另 外，所謂同軸電纜線束之至少一部分的終端，係指同軸電 纜線束中包含之複數條同軸電纜中的一部分（如40條中的 20條）同軸電纜之終端。亦可將另外之連接器裝於其餘之 終端上。 本發明之同軸電纜接續構造，宜形成有複數排前述連接 器。 200816882 如此構成之同軸電纜接續構造中，即使同軸電纜之條數 增加，因爲不增加接續於一個連接器之同軸電纜數，而增 加連接器數，故連接器之寬度不擴大。因此，在基板上接 續連接器之部位的設計自由度提高。 本發明之同軸電纜接續構造，前述同軸電纜線束之端部 宜直接裝於前述基板上。 如此構成之同軸電纜接續構造中，不將同軸電纜線束之 接續限定於連接器，而可直接接續於基板。 ^ 本發明之同軸電纜接續構造，前述同軸電纜線束之兩端 部宜分別接續於前述二個基板寬度方向的相反側。例如， 同軸電纜線束之一端若接續於上方基板之右側時，另一端 宜接續於下方基板之左側。 如此構成之同軸電纜接續構造中，即使二個基板之厚度 尺寸小，仍可確保同軸電纜大的彎曲半徑。因此，可縮小 二個基板間之間隙。 本發明之同軸電纜接續構造，各同軸電纜宜比 AWG42 w 細。 如此構成之同軸電纜接續構造，因同軸電纜係細徑，所 以富於彎曲性，可使兩基板之滑動性提高。此外，集束同 軸電纜線束時可變薄，而可謀求同軸電纜接續構造之薄型 化。 本發明之同軸電纜接續構造，宜具有以特定之寬度收容 前述同軸電纜線束的收容部。收容部可設於各基板上或收 容各基板之框體中。例如，可在至少一方之基板上設置矩 形狀之凹部。或是，亦可在至少一方之基板上設置矩形狀 200816882 之突起’而形成被壁包圍之收容部。或是，亦可將切開於 框體之溝或豎立於框體之壁所包圍的部位作爲收容部。 可將集束之同軸電纜線束的彎曲徑加上同軸電纜線束 之寬度的部分，作爲收容部之寬度。藉由以形成此寬度之 方式而切開溝或豎立壁，可限定同軸電纜線束極小之滑動 空間。滑動空間係無法配置其他零件等之空間。藉由縮小 此滑動空間，可縮小整個機器。或是在滑動空間變小之部 分，配置另外零件，藉此形成高功能化。 本發明之同軸電纜接續構造，前述同軸電纜線束宜集束 將複數個同軸電纜集束之複數個線束而構成。 如此構成之同軸電纜接續構造中，集束複數個同軸電纜 時，藉由分成複數同軸電纜之線束而集束，可減少各線束 之厚度，而可謀求同軸電纜接續構造之薄型化。 本發明之同軸電纜接續構造，在前述同軸電纜線束之至 少一端側，爲了使前述連接器之長度方向與沿著前述U字 之直線部分的方向不正交，而維持前述連接器與前述直線 部分之相對方向，宜分別調整自集束之部位至前述連接器 爲止的各同軸電纜之長度。前述連接器之長度方向與沿著 前述U字之直線部分的方向形成之角度，係藉由在基板上 配置連接器之方向來調整。例如，可將連接器之長度方向 與沿著前述U字之直線部分的方向形成平行。 本發明之同軸電纜接續構造，在直接裝於前述基板之前 述同軸電纜線束的端部安裝有接地棒，爲了使前述接地棒 之長度方向與沿著前述U字之直線部分的方向不正交’而 維持前述接地棒與前述直線部分之相對方向，宜分別調整 200816882 自集束之部位至前述接地棒爲止的各同軸電纜之 常，接地棒之長度方向係與同軸電纜線束端部上 的排列方向平行。在如此構成之同軸電纜接續構 述接地棒之長度方向與沿著前述U字之直線部分 成之角度，藉由在基板上排列各同軸電纜之方向 例如，可將接地棒之長度方向與沿著前述U字之 的方向形成平行。 本發明之同軸電纜接續構造，宜在前述同軸電 兩端部最接近的狀態下，前述同軸電纜線束相對 字之彎曲起點在長度方向兩側3mm之範圍內，未 同軸電纜。 此外，本發明之同軸電纜接續構造，宜在前述 線束之兩端部最遠離的狀態下，前述同軸電纜線 前述U字之彎曲起點在長度方向兩側3mm之範園 束前述同軸電纜。在同軸電纜線束之兩端部最遠 下，亦可說是同軸電纜線束係J字狀，本發明中 電纜線束整體形成U字狀，係亦包含〗字狀者。 同軸電纜線束彎曲成U字狀時，向U字之彎曲 側彎曲之力集中。藉由在此部位不集束，解除同 動而彎曲的負荷，可防止同軸電纜之導體斷開等 使用同軸電纜接續構造時，由於大部分是其兩端 近之狀態或最遠離之狀態的情況，因此’藉由形 狀態下之U字彎曲起點附近不集束各同軸電纜之 部分情況下，可解除施加於各同軸電纜彎曲之力 U字之彎曲起點在兩側3mm之範圍不集束，反覆 長度。通 之各電線 造中，前 的方向形 來調整。 直線部分 纜線束之 於前述U 集束前述 同軸電纜 束相對於 1內，未集 離的狀態 所謂同軸 起點的兩 軸電纜移 的損傷。 部係最接 成在此等 .構造，大 。藉由自 丨使兩基板 -10- 200816882 來回滑動時，同軸電纜斷線前之來回滑動次數大幅增加， 對同軸電纜之彎曲的耐用性大幅提高。藉由自U字之彎曲 起點在兩側5mm之範圍不集束，對同軸電纜之彎曲的耐用 性進一步提高。 本發明之同軸電纜接續構造，前述同軸電纜宜間歇地在 複數處集束。 在如此構成之同軸電纜接續構造中，因爲間歇地複數處 設置不集束部位，所以可輕易解除整體施加於同軸電纜之 彎曲的負荷，不論同軸電纜線束之彎曲位置爲何，均可防 止同軸電纜之損傷。各同軸電纜只須在不致散亂之程度下 間歇地集束即可。 另外，前述同軸電纜可形成藉由以6mm以上之間隔間歇 地集束，而輕易解除彎曲之負荷，以10mm以上之間隔間 歇地集束時，更輕易地解除彎曲之負荷的構造。 本發明之同軸電纜接續構造，前述同軸電纜宜藉由線或 膠帶，以螺旋狀地隔著間隙纏繞之方式而集束。 在如此構成之同軸電纜接續構造中，與間歇地在複數處 集束之構造同樣地，可輕易解除整體施加於同軸電纜之彎 曲的負荷。 本發明之同軸電纜接續構造，前述同軸電纜宜藉由在形 狀上已記憶成筒狀的螺旋狀膠帶，隔著間隙而集束。 在如此構成之同軸電纜接續構造中，與間歇地在複數處 集束之構造同樣地，可輕易解除整體施加於同軸電纜之彎 曲的負荷。此外，因爲形狀上已記憶成筒狀’所以容易維 持集束之狀態。 -11- 200816882 另外，膠帶雖可採用具有接合性而接合於同軸電纜者， 及非接合性者，但是從彎曲時同軸電纜對膠帶滑行，而在 長度方向上移動者容易解除負荷之觀點，宜使用不接合之 膠帶。 本發明之同軸電纜接續構造，前述同軸電纜宜被筒狀編 織套管覆蓋而集束。 在如此構成之同軸電纜接續構造中，如接合膠帶不接合 同軸電纜，而同軸電纜可在長度方向上容易移動之狀態下 集束。再者，可使套管本身扁平化，使集束之部位扁平化 而減少線束之厚度，而可謀求同軸電纜接續構造之薄型化。 本發明之同軸電纜線束，係使用於上述本發明之同軸電 纜接續構造者。 如此構成之同軸電纜線束，成爲用於接續相對地移動之 基板間的同軸電纜線束，其彎曲性方面之機械可靠性、減 少機器內需要之空間、阻抗匹配及EMI特性方面之電氣特 性優異。 本發明之攜帶式終端機，係具備上述本發明之同軸電纜 接續構造者。 如此構成之攜帶式終端機，藉由將上述同軸電纜接續構 造適用於搭載於攜帶式終端，而相對地滑動之基板的接 續，而成爲小型且可實施高密度之資訊處理者。 此外，本發明之同軸電纜線束及同軸電纜接續構造，可 適切組合上述之較佳形態。 (發明之效果） 本發明之同軸電纜接續構造可獲得，使上下之基板滑 -12- 200816882 動時，連繫兩基板之同軸電纜線束彎曲性方面之機械可靠 性優異，隨著上下基板之滑動而滑動的空間小，阻抗匹配 及EMI特性方面之電氣特性優異的效果。本發明比上下重 疊而滑動之二個基板的接續使用FPC之情況，可縮小兩基 板之間隙。 【實施方式】 以下，依據圖式詳細說明本發明之實施形態之例。 如第1圖及第2圖所示，本實施形態之同軸電纜接續構 造10係以包含複數條（20〜60條）之同軸電纜24的同軸電 纜線束20，接續上下重疊配置並前後（第1圖、第2圖之 左右方向）地滑動之二個基板1 1、1 2間者。而後，同軸電 纜線束20除了兩端部2 1 a、21 b之外，將複數之同軸電纜 24集束，整體以成爲U字狀之方式接續於兩基板。藉此， 可將同軸電纜線束20形成在基板11、12之平面觀察方向 上爲U字狀形狀，而配線於兩基板1 1、1 2間。第1圖及第 2圖之另外形態，亦可爲在長度方向上間歇地集束同軸電 纜24。另外，第1圖係同軸電纜線束20之兩端部21a、21b 最遠離之狀態，第2圖係兩端部21a、21b最接近之狀態。 基板1 1、12之滑動行程爲如30mm至60mm程度。 同軸電纜24係在正交於中心軸之徑方向的剖面中，自 中心向外側而具有：中心導體、內部絕緣體、外部導體及 被覆的結構，各個端部2 1 a、2 1 b實施終端處理，外部導體、 內部絕緣體及中心導體係階段性地各以特定長度露出。此 外，同軸電纜線束20中，除了複數條同軸電纜之外，亦可 包含無外部導體之絕緣電纜。另外，圖式中係將同軸電纜 •13- 200816882 24之數量減少顯示以簡略化。 同軸電纜線束20從平面圖觀察，在基板之寬度方向（第 1(A)圖之兩個箭頭W之方向）上彎曲。由於基板寬度爲數 cm，因此可充分確保此方向之彎曲徑。如第1(A)圖所示， 同軸電纜線束20之一方端部2 1 a對滑動方向而接續於上基 板1 1之右側（第1圖中之上側）時，另一方之端部21 b則 對滑動方向，接續於下基板1 2之左側（第1圖中之下側）。 同軸電纜線束20彎曲成U字-狀，不過，爲了縮小收容同軸 電纜線束20之空間（參照第5圖之收容部1 3 )，宜儘量縮 小U字之寬度（直線部分之間隔）。 藉由將同軸電纜線束20大致沿著基板1 1、1 2的平面彎 曲，可在同軸電纜線束20中確保充分之彎曲半徑。使用先 前之FPC時，由於FPC係在兩基板U、12之間彎曲，因此， 爲了確保其彎曲徑，需要擴大兩基板i 1、1 2之間隙，不過， 本發明無須爲了使用FPC般而擴大兩基板1 1、12之間隙， 而可謀求機器之薄型化。 如第3(A)圖及第3(B)圖所示，同軸電纜線束20第係以 捆紮膠帶23將複數條同軸電纜24集束而形成，如第3(C) 圖所示，最好形成使橢圓形剖面之厚度尺寸hi儘量小之形 狀。捆紮膠帶23如將氟樹脂膠帶、PET膠帶或橡膠材料等’ 在複數條同軸電纜24上捲繞成螺旋狀，而形成同軸電纜線 束20。可除兩端部21a、21b之外，整體捲繞捆紮膠帶23, 不過，亦可如第9圖所示，間歇地集束。宜在與基板1 1、 12及收容部13(參照第5圖）之壁面接觸之處，捲繞膠帶 等而集束，藉此，提高同軸電纜線束20對摩擦之耐用性。 -14 - 200816882 在與框體之壁面等的滑動性之點，可涵蓋同軸電纜之大致 全長，而螺旋纏繞摩擦係數低之捆紮膠帶（如PTFE、PFA、 FEP、ETFE等之氟樹脂膠帶），而在柔軟性之點可間歇地集 束。另外，亦可如第17圖所示地包覆軟管，來取代螺旋狀 地捲繞捆紮膠帶23。 同軸電纜24最好使用例如比AWG(美國線規 ;American Wire Gage )之規格的AWG42更細之極細同軸電纜。藉此， 同軸電纜線束20彎曲容易，可減少兩基板11、12滑動時 之抵抗。此外，將複數條同軸電纜24集束而形成同軸電纜 線束20時，可將同軸電纜線束20之厚度hi (參照第3(C) 圖）形成較薄，而可謀求同軸電纜接續構造1〇之薄型化。 如由於AWG42之極細同軸電纜的外徑約爲0.3mm，因此， 在高度方向即使排6層，同軸電纜線束之厚度仍在2mm以 內。另外，FPC如專利文獻1之第5圖（附加於本說明書 之第19圖）所示，由於在上下基板間係將FPC二折之方式 而彎曲，因此基板間隙之高度須確保3mm以上。亦即，使 用本實施形態之同軸電纜線束20的同軸電纜接續構造 1 0，比上下重疊而滑動之二個基板1 1、1 2的接續使用FPC 時，可縮小兩基板1 1、1 2之間隙。 同軸電纜線束20係包含20至60條之同軸電纜24者。 同軸電纜24係AWG42之細度，同軸電纜線束20包含20 條之同軸電纜24情況下，剖面爲接近圓形形狀之線束’而 形成同軸電纜線束20時，其外徑（厚度）約爲1.7mm ’將 此同軸電纜線束20配置成U字狀時，其U字之寬度可限 制在5mm以內。雖隨著芯數（同軸電纜24之條數）之增 -15- 200816882 加，U字的寬度亦擴大，但是，即使集束60條AWG42之 同軸電纜24，仍可使其U字之寬度在l〇mm以內。另外， 須傳送之資訊量多的機器中，係使用包含40條以上之同軸 電纜24的同軸電纜線束20。 此外，如第4圖所示，同軸電纜線束20可將集束複數 條同軸電纜24的複數（此處爲2條）線束20a、20b並列， 進一步捲繞捆紮膠帶23而形成。藉此，如第4(C)圖所示， 可進一步減少同軸電纜線束20之厚度h2(<hl)，而可謀求 (同軸電纜接續構造1 0之薄型化。即使同軸電纜2 4之條數 增加，線束之厚度不致變厚，因此此形態特別有效。 如第1圖至第3圖所示，最好在同軸電纜線束20之一 端或兩端安裝連接器25，以便於接續基板1 1、1 2。將同軸 電纜線束20形成複數線束之情況，而將同軸電纜24之終 端附加連接器時，如第4圖所示，可分成二個，而安裝各 個線束20a、20b共用之連接器25a、25b。第4圖中，二個 線束20 a、20b之長度不同，不過亦可形成大致相同之長度。 ί ^ 如第10圖所示，亦可將二個線束20a、20b接續於一個共 用之連接器25。亦可不將線束20a、20b進一步集束’而將 兩者接續於一個連接器。 如第5圖所示，最好在基板1 1、12中設置以特定之寬 度收容同軸電纜線束20的收容部13。如第5(A)圖所示， 收容部1 3可設置矩形狀之凹部1 3 a。藉此，由於可使同軸 電纜線束20隨著兩基板1 1、1 2之相對滑動的U字狀變形 在收容部1 3內進行，因此可防止同軸電纜線束20接觸或 掛於同軸電纜24安裝於基板11、12之電氣零件，及在基 -16- 200816882 板11、12附近之電氣零件等。此外，兩基板11、12可平 滑地滑動。或是如第5 (B)圖所示，亦可在基板11、1 2上形 成如矩形狀地設置突起13b，而被壁包圍之收容部13° 第6(A)圖係顯示使攜帶式終端機之例的滑動型行動電 話伸長狀態的斜視圖。第6(B)圖係顯示關閉滑動型之行動 電話之狀態的斜視圖。 第6圖所示之行動電話30係應用上述之同軸電纜接續 構造10。此行動電話30具有：彼此可滑動之上框體31及 下框體3 2，兩框體3 1、3 2中分別搭載有前述之基板1 1、 12，此等係藉由同軸電纜線束20而接續。 如此構成之行動電話30中，可兼顧同軸電纜接續構造 之機械可靠性與電氣特性。此外，可減少兩基板之間隙而 減薄行動電話3 0。採用本發明時，此種滑動型之行動電話 的滑動行程爲30至60mm，並宜爲40mm程度，上下基板 間之間隔爲2mm以下，基板間之電氣接續時需要之配線的 收容部寬度可爲20mm以下，進一步可爲10mm以下。 另外，本發明之同軸電纜接續構造1 0及使用於此構造 之同軸電纜線束20，並不限定於前述之實施形態，而可作 適切之變形及改良等。另外，在與前述之部位共同之部位 上註記相同符號，並省略重複之說明。 如，前述之實施形態中，係例示藉由1條同軸電纜線束 20而接續上下之基板1 1、12的情況，不過，亦可如第7 圖所示，使用複數條同軸電纜線束2 0來接續兩基板11、 12。第7(A)圖係顯示兩基板11、12之重疊爲最大狀態（關 閉狀態）之平面圖，第7(B)圖係顯示兩基板11、12之重疊 -17- 200816882 爲最小狀態（打開狀態）之平面圖。將連接器25a、25b接 續於基板1 1、1 2之部位，只要可將同軸電纜線束20形成U 字狀，可爲基板1 1、1 2上之任意部位。 此外，前述之實施形態中，係說明在同軸電纜線束20 之端部21a、21b上安裝有連接器25(25a、25b)之情況，不 過如第8圖所示，亦可將同軸電纜線束20之同軸電纜24 直接裝於基板1 1、1 2。將同軸電纜24直接裝於基板1 1、 1 2之情況下，可將同軸電纜24之終端的中心導體銲接於基 ( 板11、12之接續端子上而接續。亦可直接裝於基板11、12 之一面（第8(A)圖），直接裝於基板11、12之端部時，亦 可直接裝於兩面（第8(B)圖）。接續於上方之基板11時， 係裝於其下面，而接續於下方之基板12時，係裝於其上 面。不限定於直接安裝，以連接器等接續於基板1 1、1 2時， 亦可接續於基板1 1、1 2之兩面。 此外，本發明之同軸電纜線束中可適切地混合不具外部 導體之絕緣電線。而可使用絕緣電線作爲接地，或是使用 V 絕緣電線作爲饋電線。 此外，前述之實施形態中，同軸電纜線束2 0對基板1 1、 1 2之接續部位（連接器25、對基板直接安裝）的同軸電纜 24之方向，係與沿著同軸電纜線束20之U字的直線部分 之方向一致，不過，亦可使接續部位之同軸電纜24的方向 與同軸電纜線束20之U字的直線部分之方向不同。 如第1 1圖所示，亦可不使安裝於同軸電纜線束20之端 部21a、21b的連接器25之長度方向，與沿著同軸電纜線 束20之U字的直線部分之方向（第11圖之左右方向）不 -18- 200816882 正交，而係一致。 此外，如第1 2圖所示，亦可將同軸電纜線束20之 2 1 a、2 1 b直接裝於基板1 1、1 2，使分別安裝於各端部 21b之接地棒26之長度方向，與沿著同軸電纜線束20 字的直線部分之方向（第12圖之左右方向）不正交， 一致。另外，接地棒26共用地接續於各同軸電纜24 終端處理而露出之外部導體，再者，接續於基板1 1、 接地端子。 ^ 第1 1圖或第1 2圖所示之情況，接續部位之同軸電 的方向，係與同軸電纜線束20之U字的直線部分之方 交，不過，這是其中一例，在端部21a、21b上，彎曲 軸電纜24之角度不拘。不過，在端都21a、21b，爲了 電纜24以與到此處之方向（線束之U字的直線方向） 30度以上之方式而彎曲，且爲了維持與連接器25或接 26之U字之直線部分的相對方向，而分別調整自集束 位至連接器25或接地棒26爲止之各同軸電纜24的長 〇 藉此，在端部21a、21b上之各同軸電纜24的長度， 在彎曲之外側者同長。本發明之同軸電纜線束的一形 可如此使各電纜之長度不同作調整，來形成連接器25 地棒26對基板1 1、1 2之方向，亦即將同軸電纜線束 端部朝向希望之方向。可自由設計在基板上安裝同軸 線束20之角度及方向。亦即，基板丨丨、！ 2之設計自 提高。 此形態之同軸電纜線束20，準備藉由在端部彎曲同

如第4圖所示，在一個同軸電纜線束2〇之一端複數安 裝連接器25時，亦是各連接器25或各接地棒26之長度方 向與沿者问軸電續線束20之U字的直線部分之方向不正 交’爲了維持連接器25或接地棒26與前述直線部分之相 對方向，亦可分別調整自各電纜24所集束之部位至前述連 f \ % ； 接器爲止之各同軸電纜24的長度。 在一個同軸電纜線束20之一端，將同軸電纜24分成複 數群，各群安裝連接器25或接地棒26時，或是，將同軸 電纜線束20進一步集束成複數同軸電纜24之線束者，且 各線束安裝連接器25或接地棒26時亦同。 前述之實施形態中，係例示除了同軸電纜線束20之端 部21 a、2 1 b以外的部分，以捆紮膠帶23集束之形態，不 過，集束同軸電纜24之形態並不限定於此。各同軸電纜24 夂 亦可以不覆蓋整體之方式而集束，只須使基板11、12滑動 時，可維持線束形狀之程度而局部集束即可。使基板1 1、 12滑動時，同軸電纜24與基板11、12及設於基板11、12 之壁面接觸的部位，宜纒繞膠帶等，以提高對摩擦之耐用 性。此外，捆紮膠帶23可採用具有接合性而接合於同軸電 纜24者，或是非接合性者，不過，由於彎曲時同軸電纜24 對捆紮膠帶滑行而在長度方向上移動者，容易解除彎曲之 負荷，因此宜爲非接合性者。 將同軸電纜線束20接續於上下之基板11、12，自兩基 -20- 200816882 板11、12之重疊爲最大之位置（第2圖之狀態）至兩基板 1 1、12之重疊爲最小之位置（第1圖之狀態）爲止，反覆 使兩基板11、1 2來回滑動，來調查滑動之來回次數（以下 稱滑動次數）與同軸電纜24之中心導體的斷線之關係。結 果瞭解在同軸電纜24之彎曲起點（U字形狀之直線部與曲 線部的邊界點）附近，同軸電纜24不集束時，斷線前之滑 動次數大幅提高。從實驗瞭解，夾著彎曲起點，宜在兩側 之3mm範圍，不同軸電纜24集束，更宜在兩側之5mm範 ί 圍，不同軸電纜24集束。 其理由係認爲如下： 同軸電纜線束20彎曲時，在彎曲部之內側與外側產生 長度之差。此時若可自由地移動各同軸電纜24時，內側之 同軸電纜24鬆弛而吸收長度之差。 但是，纒繞膠帶等而集束同軸電纜24時，各同軸電纜 24被拘束而無法移動或移動困難，無法吸收長度之差，在 彎曲部之兩端，對同軸電纜24施加彎曲應力。亦即，彎曲 (/ 之負荷容易集中於同軸電纜24之彎曲起點（U字形狀之直 線部與曲線部的邊界點）。使基板1 1、1 2不斷滑動，而在 彎曲應力造成之負荷集中的部位，而認爲造成同軸電纜24 之中心導體等斷裂。因而，容易產生彎曲應力之部位，亦 即彎曲起點附近，同軸電纜24不宜集束而不受到拘束。 由於行動電話通常上下框體是在關閉狀態（縮短之狀 態）或是打開之狀態（伸長之狀態）的其中之一，因此， 行動電話30等使用之基板η、12,通常是在同軸電纜線束 20之兩端部21a、21b爲最接近之狀態或是最遠離之狀態。 -21- 200816882 此狀態如第1 3圖所示，係同軸電纜線束20之兩端部2 1 a、 2 1 b爲最接近之狀態，或是如第1 4圖所示，同軸電纜線束 20之兩端部21a、21b爲最遠離之狀態的其中之一。因此， 如第13圖或第14圖所示，在U字之彎曲起點A、B的附 近，如不集束同軸電纜24時，幾乎不受彎曲之應力，而可 使對應於同軸電纜線束20之彎曲的機械特性（斷線前之滑 動次數）大幅提高。 如使用AWG42〜46之同軸電纜24而形成同軸電纜線束 20時，以捆紮膠帶23集束整個多餘長度22之形態下，基 板1 1、12之滑動進行5萬次程度時，會導致同軸電纜24 之中心導體斷裂。將同軸電纜24不集束之範圍設定爲相對 於U字之彎曲起點A、B而在長度方向兩側3mm之範圍的 情況下，即使基板1 1、12之滑動進行10萬次，同軸電纜 24之中心導體仍不致斷裂，將不集束之範圍設定爲相對於 彎曲起點A、B在長度方向兩側5mm之範圍的情況下，即 使基板1 1、1 2之滑動進行1 5萬次，同軸電纜24之中心導 體仍不致斷裂。 另外，爲了維持同軸電纜線束20之線束形狀，在第1 3 圖及第1 4圖所示之狀態下，U字形狀之曲線部的一部分’ 宜以捆紮膠帶23等集束。 彎曲起點附近不集束之形態，亦包含同軸電纜線束20 之端部安裝有連接器之情況與直接裝於基板之情況。再 者，亦包含在同軸電纜線束20之端部各同軸電纜24分成 數個群，而各群安裝連接器或安裝接地棒之情況。再者’ 亦包含將複數之同軸電纜24的線束進一步集束，而成爲同 -22- 200816882 軸電纜線束20之情況。 此外，如第9圖所示，間歇地在複數處集束同軸電纜2 4 時，由於係間歇地在複數處設置並未集束之部位’因此， 整體可輕易地解除施加於同軸電纜24之彎曲負荷，不論同 軸電纜24之彎曲位置，而可防止同軸電纜24之損傷。此 外，藉由間歇地集束同軸電纜24，在同軸電纜線束20之兩 端部21a、21b爲最接近之狀態與最遠離之狀態兩者，均容 易實現不集束彎曲起點附近之形態。 各同軸電纜24爲了維持線束形狀，只須在不致散亂之 程度間歇地集束即可。如前述，由於只須隔著彎曲起點而 在3mm之範圍不集束即可，因此，間歇地集束時之間隔宜 爲6mm以上。再者，更宜爲以l〇mm以上之間隔間歇地集 束。第9圖係顯示以捆紮膠帶23集束之形態，不過，亦可 以線來集束，亦可以滴下接合劑而予以一體化之方式來集 束。 此外，如第15圖及第16圖所示，同軸電纜24亦可藉 由捆紮膠帶23 (參照第15圖）或線27 (參照第16圖）螺 旋狀地隔著間隙而捲繞來集束。第1 5圖及第1 6圖之同軸 電纜線束20，係與第9圖所示之間歇地在複數處集束之構 造同樣地’可整體輕易地解除施加於同軸電纜24之彎曲負 荷。另外’亦可在以捆紮膠帶23或線27螺旋狀地捲繞之 處的兩端’以不致產生纏繞鬆驰之方式，而以具有接合性 之捆紮膠帶23預先集束。 此外’如第1 7圖所示，亦可藉由在形狀上已記憶成筒 狀之螺旋狀的膠帶28,隔著間隙而集束同軸電纜24。螺旋 -23- 200816882 狀之膠帶28可使用使帶狀之捆紮膠帶23慣於筒狀而在形 狀上已記憶者，或是在筒狀之構件上形成螺旋狀之切槽 者。如可使用將橡膠軟管切成螺旋狀者。第17圖之同軸電 纜線束20，係與第9圖所示之間歇地在複數處集束之構造 同樣地，可整體輕易地解除施加於同軸電纜24之彎曲負 荷。此外，由於螺旋狀之膠帶28在形狀上已記憶成筒狀， 因此，容易維持集束同軸電纜24之狀態。集束時，亦是使 形狀上已記憶之膠帶或軟管包覆於同軸電纜24者，比以特 定之間距纏繞膠帶或線者作業效率高。 此外，如第1 8圖所示，亦可藉由筒狀之編織套管29被 覆集束同軸電纜24。編織套管29可使用如使金屬箔線或化 學纖維編織成筒狀者。第1 8圖之同軸電纜線束20，並非如 接合膠帶般接合同軸電纜24,而係同軸電纜24可在長度方 向上容易移動之狀態下集束。此外，將套管本身形成扁平 之形狀時，如第3(C)圖所示，可使集束之部分容易扁平化， 而可縮小收容空間。如將同軸電纜24集束成直徑爲1.9mm 之剖面圓形者上纏繞捆紮膠帶23之情況下，外徑成爲 2.3 mm，將其加壓使其扁平時，成爲高度爲1.8 mm，寬度爲 2.6mm。另外，將同軸電纜24集束成直徑爲1.9mm之剖面 圓形者，藉由編織套管29覆蓋情況下，外徑成爲2.1mm， 將其加壓使其扁平時，成爲高度爲1.3mm，寬度爲2.8mm。 第9圖、第15圖至第18圖係顯示連接器25之長度方 向的方向與同軸電纜24之長度方向（沿著U字之直線部分 的方向）平行時，亦即在端部各同軸電纜24彎曲90度之 例。此等之情況如前述，各同軸電纜24之長度不同，而分 -24- 200816882 別調整自集束之處至前述連接器25爲止之各同軸電纜24 的長度。此外，連接器25之方向並不限定於上述之圖。連 接器25之長度方向亦可與同軸電纜24之長度方向正交。 端部不裝連接器，係安裝接地棒，而直接裝於基板之同 軸電纜線束20,亦與各同軸電纜24之集束者的端部安裝連 接器時相同。 另外，上述實施形態，係可適切組合。例如，亦可在同 軸電纜線束20之一方端部21a上安裝連接器25而接續於 基板1 1，並將另一方端部2 1 b直接裝於基板1 2。此外，如 第11圖及第12圖所示，亦可適切採用使接續部位之同軸 電纜24的方向與同軸電纜線束20之U字的直線部分之方 向不同，並且爲第9圖、第13圖至第18圖所示之各種集 束的形態。 【產業上之可利用性】

OBJECTS OF THE INVENTION: 1. Field of the Invention The present invention relates to a substrate having two substrates that are overlapped and movable in a direction perpendicular to the direction of overlap, and electrically connected to the substrates using a coaxial cable. The coaxial cable connection structure, the coaxial cable harness using the structure, and the portable terminal having the aforementioned coaxial cable connection structure. [Prior Art] For example, in the case of a mobile phone, two mobile phones that can slide each other and overlap each other constitute a mobile phone, and the two frames are slid according to the use condition of the mobile phone, and the action can be extended or shortened. The length of the phone. The two housings are provided with a substrate on which various circuits and components for realizing the respective functions are arranged, and wiring members for electrically connecting the substrates are provided. Each of the substrates housed in the two frames is slid in accordance with the operation of the respective frames, and a flexible flexible substrate (FPC) is usually used as the wiring member for electrically connecting the substrates. Patent Document 1 discloses an example of using such a flexible substrate. As shown in FIG. 19, the connector 101 is connected to the substrate 100 on the lower side by a flexible printed circuit board 104 (FPC), and the circuit module provided on the upper side. Connector 103 of group 102. In order to ensure a low-resistance grounding conductor and EMI countermeasures, it is known that the one side of the FPC side is fully integrated as a grounding conductor layer. However, such fully grounded FPCs cannot ensure that the bending of the substrate is affected, and cracks may occur in the bent portion. In order to solve the problem of the flexibility of the FPC which is fully grounded as described above, Patent Document 1 discloses that the ground portion is partially removed in the curved portion, and is disposed on the back side of the curved portion of the 200816882 without being aligned with the signal line. The structure of a plurality of grounding wires. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2004-88020 (Draft of the Invention) (Problems to be Solved by the Invention) As described above, the FPC can be completely grounded in terms of electrical characteristics of the ground, but this is curved. In addition, in the case of comprehensive grounding, there is a problem that the electrical characteristics (impedance matching and EMI characteristics) deteriorate. According to Patent Document 1, a ground wire is disposed on the back surface of the bent portion, and the signal line and the ground line are disposed so as not to face each other. The data is transmitted at a high speed and the density is increased, and when the number of signal lines is increased, the width of the FPC is expanded. . It is necessary to ensure a large space for the FPC to slide between the two substrates. This is contrary to the miniaturization of the machine. SUMMARY OF THE INVENTION An object of the present invention is to provide mechanical reliability in terms of flexibility and reduction in sliding in a machine in a continuous structure between two substrates which are arranged to be overlapped and which are relatively movable in a direction perpendicular to the direction of overlap. A coaxial cable connection structure excellent in electrical characteristics in terms of space, impedance matching, and EMI characteristics, a coaxial cable harness and a portable terminal using the same. (Means for Solving the Problem) The coaxial cable connection structure of the present invention which achieves the above-described object is a coaxial cable harness including a plurality of bundled coaxial cables at least one bundle, and is connected between the two substrates which are vertically overlapped and arranged to slide. The coaxial cable is connected to 200816882. The structure is characterized in that the entire coaxial cable harness is connected in a u-shape. The coaxial cable harness used in the present invention may also not be a coaxial cable, but may include an insulated wire having no external conductor. According to the present invention, since the coaxial cable can be used in the signal line, the electrical characteristics in terms of impedance matching and EMI characteristics are good. Insulated wires without external conductors can be used for feeders and ground wires. When clustering these lines, there is no need to distinguish them from coaxial cables. When the two substrates are slid, the portion of the coaxial cable harness bent into a U-shape moves, and follows the movement of the substrate. At this time, the space (sliding space) required for the coaxial cable harness to slide is the thickness of the coaxial cable harness, and the width thereof becomes the U-shaped width. When the coaxial cable harness is formed into a flat shape having an elliptical cross section, the thickness thereof can be made thin. Thereby, the gap between the upper and lower substrates can be reduced. In addition, the width of the U word can be greatly reduced compared to the width of the substrate. Therefore, the gap between the substrates can be reduced, and the coaxial cable harness can be sufficiently slidable. In the coaxial cable connection structure of the present invention, it is preferable that a common connector is mounted at a terminal of at least a part of the aforementioned coaxial cable harness. In the coaxial cable connection structure thus constructed, since the connector is attached to the end of the coaxial cable harness, the connection to the substrate can be easily performed. Further, the terminal of at least a part of the coaxial cable harness refers to a terminal of a coaxial cable of a part of a plurality of coaxial cables (e.g., 20 of 40) included in the coaxial cable harness. Additional connectors can be attached to the remaining terminals. In the coaxial cable connection structure of the present invention, it is preferable to form a plurality of the aforementioned connectors. 200816882 In the coaxial cable connection structure thus constructed, even if the number of coaxial cables is increased, the number of connectors is increased without increasing the number of coaxial cables connected to one connector, so that the width of the connector is not enlarged. Therefore, the degree of freedom in designing the portion where the connector is continued on the substrate is improved. In the coaxial cable connection structure of the present invention, the end portion of the coaxial cable harness is preferably directly mounted on the substrate. In the coaxial cable connecting structure thus constructed, the coaxial cable harness is not limited to the connector, and can be directly connected to the substrate. In the coaxial cable connection structure of the present invention, both ends of the coaxial cable harness are preferably connected to opposite sides of the width direction of the two substrates. For example, if one end of the coaxial cable harness is connected to the right side of the upper substrate, the other end should be connected to the left side of the lower substrate. In the coaxial cable connecting structure thus constructed, even if the thickness of the two substrates is small, the large bending radius of the coaxial cable can be secured. Therefore, the gap between the two substrates can be reduced. According to the coaxial cable connection structure of the present invention, each coaxial cable should be thinner than the AWG42 w. In the coaxial cable connection structure configured as described above, since the coaxial cable has a small diameter, it is rich in flexibility, and the slidability of both substrates can be improved. In addition, the bundled coaxial cable harness can be made thinner, and the coaxial cable connection structure can be made thinner. Preferably, the coaxial cable connection structure of the present invention has a housing portion for housing the coaxial cable harness at a specific width. The accommodating portion may be provided on each of the substrates or in the housing of each of the substrates. For example, a rectangular recess may be provided on at least one of the substrates. Alternatively, the protrusions of the rectangular shape 200816882 may be provided on at least one of the substrates to form a housing portion surrounded by the wall. Alternatively, a portion that is cut into the groove of the frame or that is erected on the wall of the frame may be used as the accommodating portion. The bending diameter of the bundled coaxial cable harness can be added to the width of the coaxial cable harness as the width of the housing portion. By cutting the trench or erecting the wall in such a manner as to form this width, it is possible to define a very small sliding space of the coaxial cable harness. The sliding space cannot be configured with space for other parts and the like. By reducing this sliding space, the entire machine can be reduced. Or, in the part where the sliding space becomes smaller, another part is arranged, thereby forming a high functionality. In the coaxial cable connection structure of the present invention, the coaxial cable harness is preferably formed by bundling a plurality of bundles of a plurality of coaxial cables. In the coaxial cable connection structure configured as described above, when a plurality of coaxial cables are bundled, the bundles of the plurality of coaxial cables are bundled, whereby the thickness of each of the bundles can be reduced, and the coaxial cable connection structure can be made thinner. In the coaxial cable connection structure of the present invention, at least one end side of the coaxial cable harness is configured to maintain the connector and the straight portion in order to prevent the longitudinal direction of the connector from being orthogonal to a direction along a straight portion of the U-shape In the relative direction, it is preferable to adjust the length of each coaxial cable from the portion of the bundle to the connector. The angle formed by the longitudinal direction of the connector and the direction along the straight portion of the U-shape is adjusted by arranging the connector on the substrate. For example, the length direction of the connector may be parallel to the direction along the straight portion of the aforementioned U-shape. In the coaxial cable connection structure of the present invention, a ground rod is attached to an end portion of the coaxial cable harness directly mounted on the substrate, and the longitudinal direction of the ground rod is not orthogonal to a direction along a straight portion of the U-shape. While maintaining the opposite direction of the ground rod and the straight portion, it is preferable to adjust the coaxial cables of the self-assembled portion of the 200816882 to the ground rod, respectively, and the length direction of the ground rod is parallel to the arrangement direction on the end portion of the coaxial cable harness. . In the coaxial cable thus constructed, the length direction of the ground rod is formed at an angle with the straight portion along the U-shape, and the direction of each coaxial cable is aligned on the substrate, for example, the length direction of the ground rod can be along The directions of the aforementioned U words are formed in parallel. In the coaxial cable connection structure of the present invention, it is preferable that the coaxial cable harness has a bending starting point of 3 mm on both sides in the longitudinal direction in a state in which the end portions of the coaxial cable are closest to each other, and the coaxial cable is not coaxial. Further, in the coaxial cable connecting structure of the present invention, it is preferable that the coaxial cable has a bending starting point of the U-shape of 3 mm on both sides in the longitudinal direction in a state where the both ends of the wire harness are farthest from each other. In the farthest end portions of the coaxial cable harness, it can be said that the coaxial cable harness is J-shaped. In the present invention, the cable harness is formed in a U shape as a whole, and also includes a font. When the coaxial cable harness is bent into a U shape, the force of bending toward the curved side of the U-shape is concentrated. By not concentrating at this portion, the load that is bent in the same direction is released, and it is possible to prevent the coaxial cable from being disconnected or the like when the coaxial cable is connected, and most of them are in a state in which both ends are close to each other or the most distant state. Therefore, in the case where the respective coaxial cables are not bundled in the vicinity of the U-shaped bending starting point in the shape state, the bending starting point of the U-shaped force applied to the bending of each coaxial cable can be released without being bundled in the range of 3 mm on both sides, and the length is reversed. Through the various wires, the front direction is adjusted. The straight line portion of the cable bundle is in the U-bundle of the coaxial cable bundle with respect to 1 and is not concentrated. The so-called coaxial starting point of the two-axis cable is damaged. The department is most connected here. The structure is large. By sliding the two substrates -10- 200816882 back and forth, the number of back and forth slides before the coaxial cable is broken is greatly increased, and the durability of the bending of the coaxial cable is greatly improved. The durability of the bending of the coaxial cable is further improved by not bundling the starting point of the U-shape from 5 mm on both sides. In the coaxial cable connection structure of the present invention, the coaxial cable is preferably bundled intermittently at a plurality of points. In the coaxial cable connection structure thus constructed, since the bundle portion is not provided intermittently, the load applied to the bending of the coaxial cable can be easily released, and the damage of the coaxial cable can be prevented regardless of the bending position of the coaxial cable harness. . Each coaxial cable must be bundled intermittently without being scattered. In addition, the coaxial cable can be formed by intermittently bundling at intervals of 6 mm or more, and the bending load can be easily released, and the bending load can be more easily released when the bundle is intermittently stacked at intervals of 10 mm or more. In the coaxial cable connecting structure of the present invention, the coaxial cable is preferably bundled by a wire or a tape so as to be wound in a spiral shape with a gap interposed therebetween. In the coaxial cable connecting structure configured as described above, the load applied to the bending of the coaxial cable can be easily released in the same manner as the structure in which the plurality of bundles are intermittently bundled. In the coaxial cable connecting structure of the present invention, the coaxial cable is preferably bundled by a gap between the spiral fibers which have been memorized in a cylindrical shape. In the coaxial cable connecting structure configured as described above, the load applied to the bending of the coaxial cable can be easily released in the same manner as the structure in which the plurality of bundles are intermittently bundled. Further, since the shape has been memorized in a cylindrical shape, it is easy to maintain the state of the bundle. -11- 200816882 In addition, although the tape can be joined to the coaxial cable by bonding, and the non-joining person can be used, it is preferable that the coaxial cable slides on the tape during bending and the load is easily released in the longitudinal direction. Use unbonded tape. In the coaxial cable splicing structure of the present invention, the coaxial cable is preferably covered by a cylindrical woven sleeve and bundled. In the coaxial cable connecting structure thus constructed, if the bonding tape does not engage the coaxial cable, the coaxial cable can be bundled in a state where it is easy to move in the longitudinal direction. Further, the sleeve itself can be flattened, the portion of the bundle can be flattened, and the thickness of the bundle can be reduced, and the coaxial cable connection structure can be made thinner. The coaxial cable harness of the present invention is used in the above-described coaxial cable connecting structure of the present invention. The coaxial cable harness thus constructed is a coaxial cable harness for continuously moving between the substrates, and is excellent in electrical reliability in terms of flexibility, space required in the machine, impedance matching, and EMI characteristics. The portable terminal of the present invention is provided with the above-described coaxial cable connecting structure of the present invention. The portable terminal device configured as described above is suitable for use as a small-sized and high-density information processor by the above-described coaxial cable connection structure being applied to a portable terminal mounted on a portable terminal. Further, in the coaxial cable harness and the coaxial cable connecting structure of the present invention, the above preferred embodiments can be combined as appropriate. (Effect of the Invention) The coaxial cable connection structure of the present invention can be obtained, and when the upper and lower substrates are slid -12-200816882, the mechanical reliability of the coaxial cable harness connecting the two substrates is excellent, and the sliding of the upper and lower substrates is performed. The sliding space is small, and the electrical characteristics of the impedance matching and EMI characteristics are excellent. In the case where the FPC is used in connection with the two substrates which are overlapped and slid in the present invention, the gap between the two substrates can be reduced. [Embodiment] Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. As shown in Fig. 1 and Fig. 2, the coaxial cable connection structure 10 of the present embodiment is a coaxial cable harness 20 including a plurality of coaxial cables 24 (20 to 60), which are arranged one above the other and are placed one behind the other (first In the figure, the left and right directions of Fig. 2 are slid between the two substrates 1 1 and 1 2 . Then, the coaxial cable harness 20 is bundled with a plurality of coaxial cables 24 in addition to the both end portions 2 1 a and 21 b, and is connected to the two substrates in a U-shape as a whole. Thereby, the coaxial cable harness 20 can be formed in a U-shape in the plane in which the substrates 11 and 12 are viewed in the plane, and can be wired between the two substrates 1 1 and 12. In another form of Fig. 1 and Fig. 2, the coaxial cable 24 may be bundled intermittently in the longitudinal direction. In addition, the first figure is the state in which the both end portions 21a and 21b of the coaxial cable harness 20 are the farthest, and the second figure is the state in which both end portions 21a and 21b are closest to each other. The sliding stroke of the substrates 1 1 and 12 is, for example, about 30 mm to 60 mm. The coaxial cable 24 has a center conductor, an inner insulator, an outer conductor, and a covered structure in a cross section orthogonal to the central axis, and the end portions 2 1 a, 2 1 b are subjected to terminal processing. The outer conductor, the inner insulator and the center conductor are each exposed in a specific length. In addition, the coaxial cable harness 20 may include an insulated cable without an external conductor in addition to a plurality of coaxial cables. In addition, in the figure, the number of coaxial cables • 13-200816882 24 is reduced to show abbreviated. The coaxial cable harness 20 is bent in the width direction of the substrate (the direction of the two arrows W in the first (A) view) as viewed in a plan view. Since the substrate has a width of several cm, the bending diameter in this direction can be sufficiently ensured. As shown in Fig. 1(A), when one end portion 2 1 a of the coaxial cable harness 20 is connected to the right side of the upper substrate 1 1 (the upper side in Fig. 1) in the sliding direction, the other end portion 21 b Then, the sliding direction is continued to the left side of the lower substrate 12 (the lower side in FIG. 1). The coaxial cable harness 20 is bent in a U-shape. However, in order to reduce the space for accommodating the coaxial cable harness 20 (refer to the accommodating portion 13 of Fig. 5), it is preferable to reduce the width of the U-shape (the interval between the straight portions) as much as possible. By bending the coaxial cable harness 20 substantially along the plane of the substrates 1, 1 and 12, a sufficient bending radius can be secured in the coaxial cable harness 20. When the conventional FPC is used, since the FPC is bent between the two substrates U and 12, it is necessary to enlarge the gap between the two substrates i1 and 1 2 in order to secure the bending diameter. However, the present invention does not need to be expanded in order to use FPC. The gap between the two substrates 1 1 and 12 can reduce the thickness of the machine. As shown in the third (A) and third (B) drawings, the coaxial cable harness 20 is formed by bundling a plurality of coaxial cables 24 with a binding tape 23, as shown in Fig. 3(C), preferably formed. Make the thickness dimension hi of the elliptical profile as small as possible. The binding tape 23 is wound into a spiral shape by arranging a fluororesin tape, a PET tape, a rubber material or the like on a plurality of coaxial cables 24 to form a coaxial cable bundle 20. The binding tape 23 may be wound around the entire end portions 21a and 21b. However, as shown in Fig. 9, it may be intermittently bundled. It is preferable to bundle the tape or the like at a position where it contacts the wall surfaces of the substrates 1 1 and 12 and the accommodating portion 13 (see Fig. 5), thereby improving the durability of the coaxial cable harness 20 against friction. -14 - 200816882 A tying tape (such as a fluororesin tape of PTFE, PFA, FEP, ETFE, etc.) that covers the entire length of the coaxial cable and has a low spiral friction coefficient at a point of slidability with the wall surface of the frame, etc. At the point of softness, it can be bundled intermittently. Alternatively, the hose may be wrapped as shown in Fig. 17, instead of spirally winding the binder tape 23. The coaxial cable 24 preferably uses, for example, a very thin coaxial cable that is thinner than the AWG 42 of the AWG (American Wire Gage) specification. Thereby, the coaxial cable harness 20 is easily bent, and the resistance of the two substrates 11 and 12 when sliding can be reduced. Further, when the plurality of coaxial cables 24 are bundled to form the coaxial cable harness 20, the thickness hi of the coaxial cable harness 20 (see FIG. 3(C)) can be made thin, and the coaxial cable connection structure can be thinned. Chemical. For example, since the outer diameter of the ultra-fine coaxial cable of the AWG 42 is about 0.3 mm, even if it is 6 layers in the height direction, the thickness of the coaxial cable harness is still within 2 mm. Further, as shown in Fig. 5 of Patent Document 1 (attached to Fig. 19 of the present specification), the FPC is bent by folding the FPC between the upper and lower substrates, so that the height of the substrate gap must be 3 mm or more. In other words, when the coaxial cable connection structure 10 of the coaxial cable harness 20 of the present embodiment is used, when the two substrates 1 1 and 1 2 that are slid over the upper and lower sides are connected, the two substrates 1 1 and 1 2 can be reduced. gap. The coaxial cable harness 20 is comprised of 20 to 60 coaxial cables 24. The coaxial cable 24 is the fineness of the AWG 42. When the coaxial cable harness 20 includes 20 coaxial cables 24, the cross section is a wire harness close to a circular shape, and when the coaxial cable harness 20 is formed, the outer diameter (thickness) is about 1.7 mm. When the coaxial cable harness 20 is arranged in a U shape, the width of the U word can be limited to 5 mm or less. Although the number of cores (the number of coaxial cables 24) is increased by -15-200816882, the width of the U-word is also expanded, but even if the bundle of 60 AWG42 coaxial cables 24 is bundled, the width of the U-shape can be made l. Within 〇mm. Further, in a machine having a large amount of information to be transmitted, a coaxial cable harness 20 including 40 or more coaxial cables 24 is used. Further, as shown in Fig. 4, the coaxial cable harness 20 can be formed by juxtaposing a plurality of (here, two) bundles 20a and 20b of a plurality of bundled coaxial cables 24, and further winding the binder tape 23. Thereby, as shown in FIG. 4(C), the thickness h2 of the coaxial cable harness 20 can be further reduced ( <hl), and it is possible to reduce the thickness of the coaxial cable connection structure 10. Even if the number of the coaxial cables 24 is increased, the thickness of the wire harness does not become thick, so this form is particularly effective. As shown in Figs. 1 to 3 As shown, it is preferable to mount the connector 25 at one or both ends of the coaxial cable harness 20 to facilitate the connection of the substrates 1 1 and 12. The coaxial cable harness 20 is formed into a plurality of harnesses, and the terminals of the coaxial cable 24 are additionally connected. When the device is as shown in Fig. 4, it can be divided into two, and the connectors 25a and 25b shared by the respective wire harnesses 20a and 20b are mounted. In Fig. 4, the lengths of the two wire harnesses 20a and 20b are different, but they can also be formed. Roughly the same length. ί ^ As shown in Fig. 10, the two wire harnesses 20a, 20b may be connected to a common connector 25. The wire harnesses 20a, 20b may not be further bundled to connect the two to one connection. As shown in Fig. 5, it is preferable to provide the accommodating portion 13 for accommodating the coaxial cable harness 20 with a specific width in the substrates 1 1 and 12. As shown in Fig. 5(A), the accommodating portion 13 can be provided with a rectangular shape. a recess 1 3 a. Thereby, since the coaxial cable harness can be Since the U-shaped deformation of the relative sliding of the two substrates 1 1 and 1 2 is performed in the accommodating portion 13 , it is possible to prevent the coaxial cable harness 20 from coming into contact with or hanging on the electrical components of the coaxial cables 24 mounted on the substrates 11 and 12 . And electrical components in the vicinity of the bases 11 to 200816882, 11 and 12. In addition, the two substrates 11 and 12 can be smoothly slid, or as shown in Fig. 5(B), on the substrates 11, 12 The accommodating portion 13 is formed in a rectangular shape, and the accommodating portion 13 is surrounded by the wall. Fig. 6(A) is a perspective view showing the state in which the slide type mobile phone of the portable terminal is in an extended state. Fig. 6(B) A perspective view showing a state in which the slide type mobile phone is turned off. The mobile phone 30 shown in Fig. 6 applies the above-described coaxial cable connection structure 10. The mobile phone 30 has a frame 31 and a lower frame that are slidable from each other. The body 3 2 and the above-mentioned substrates 1 1 and 12 are respectively mounted on the two frames 3 1 and 3 2 , and these are connected by the coaxial cable harness 20 . In the mobile phone 30 configured as described above, the coaxial cable connection structure can be considered. Mechanical reliability and electrical characteristics. In addition, it can reduce the distance between the two substrates. The mobile phone 30 is thinned and thinned. When the present invention is used, the sliding stroke of the sliding type mobile phone is 30 to 60 mm, and preferably 40 mm, and the interval between the upper and lower substrates is 2 mm or less, and electrical connection between the substrates is performed. The width of the accommodating portion of the wiring to be used may be 20 mm or less, and may be 10 mm or less. The coaxial cable connecting structure 10 of the present invention and the coaxial cable harness 20 using the same are not limited to the above-described embodiments. The same reference numerals will be given to the same parts as the above-mentioned parts, and the overlapping description will be omitted. For example, in the above-described embodiment, the upper and lower substrates 1 1 and 12 are connected by one coaxial cable harness 20, but a plurality of coaxial cable harnesses 20 may be used as shown in FIG. The two substrates 11, 12 are connected. Fig. 7(A) shows a plan view in which the overlap of the two substrates 11 and 12 is in the maximum state (closed state), and Fig. 7(B) shows the overlap of the two substrates 11 and 12 in the minimum state -17-200816882 (open state) ) The plan. The connectors 25a and 25b are connected to the portions of the substrates 1 1 and 1 2, and the coaxial cable harness 20 can be formed in a U shape, and can be any portion on the substrates 1 1 and 1 2 . Further, in the above-described embodiment, the connector 25 (25a, 25b) is attached to the end portions 21a, 21b of the coaxial cable harness 20, but as shown in Fig. 8, the coaxial cable harness 20 may be used. The coaxial cable 24 is directly mounted on the substrates 1 1 and 12. When the coaxial cable 24 is directly mounted on the substrate 1 1 and 1 2, the center conductor of the terminal end of the coaxial cable 24 can be soldered to the base (the connection terminals of the boards 11 and 12 to be connected. It can also be directly mounted on the substrate 11, One of the 12 faces (Fig. 8(A)) can be directly attached to both ends of the substrates 11 and 12 (Fig. 8(B)). When connected to the upper substrate 11, it is attached to When it is connected to the substrate 12 below, it is attached to the substrate 12. It is not limited to direct mounting, and may be connected to both sides of the substrate 1 1 and 1 2 when the connector or the like is connected to the substrate 1 1 and 1 2 . Further, in the coaxial cable harness of the present invention, an insulated wire having no external conductor can be appropriately mixed, and an insulated wire can be used as the grounding or a V insulated wire can be used as the feeding wire. Further, in the above embodiment, the coaxial cable harness is used. The direction of the coaxial cable 24 of the connection portion of the substrate 1 1 and 1 2 (the connector 25 and the substrate is directly mounted) is the same as the direction of the straight line along the U-shape of the coaxial cable harness 20, however, The side of the coaxial cable 24 that can make the connection portion The direction to the straight portion of the U-shape of the coaxial cable harness 20 is different. As shown in Fig. 1, the longitudinal direction of the connector 25 attached to the end portions 21a, 21b of the coaxial cable harness 20 may not be The direction of the straight portion of the U-shape of the coaxial cable harness 20 (the left-right direction of FIG. 11) is not -18-200816882 orthogonal, but is uniform. Further, as shown in FIG. 2, the coaxial cable harness 20 can also be used. 2 1 a, 2 1 b are directly mounted on the substrates 1 1 and 1 2 so as to be respectively attached to the length direction of the ground bar 26 of each end portion 21b and the direction of the straight line portion along the line of the coaxial cable harness (Fig. 12) The left and right directions are not orthogonal to each other. In addition, the ground rods 26 are connected to the external conductors exposed by the respective ends of the coaxial cables 24, and are connected to the substrate 1 1 and the ground terminals. ^ Figure 1 1 or In the case shown in Fig. 2, the direction of the coaxial electric power of the splicing portion intersects with the straight portion of the U-shaped line of the coaxial cable harness 20, but this is an example, and the bent shaft cable is provided at the end portions 21a, 21b. The angle of 24 is not limited. However, at the end 21a, 21b, in order The cable 24 is bent 30 degrees or more in the direction to the direction (the linear direction of the U-shaped wire harness), and is adjusted separately in order to maintain the relative direction of the straight portion of the U-shaped connector 25 or the joint 26 The length of each coaxial cable 24 from the bundle to the connector 25 or the grounding bar 26 is such that the length of each of the coaxial cables 24 on the end portions 21a, 21b is the same as the length of the other side of the bend. The coaxial cable of the present invention The shape of the wire harness can be adjusted such that the lengths of the cables are different to form the direction of the connector 25 to the substrate 1 1 , 1 2 , that is, the end of the coaxial cable harness is oriented in the desired direction. The angle and direction of mounting the coaxial harness 20 on the substrate can be freely designed. That is, the substrate 丨丨,! The design of 2 is self-improvement. In the coaxial cable harness 20 of this form, the coaxial cable 24 of the required length calculated by bending the angle of the cable 24 at the end is prepared, and the end portion 21a, the U is passed through the 12 cable 24 Each will form the part of the ground rod: degrees. When the cable is connected to the coaxial cable 24, the coaxial cable 24 is arranged according to the determined length. Each of the coaxial cables 24 at the mutual position is determined by the assembly of the connector 25 or the ground rod 26 by a bundle such as a tape. As shown in FIG. 4, when the connector 25 is mounted at a plurality of ends of a coaxial cable harness 2, the length direction of each connector 25 or each of the ground bars 26 and the U-shaped wire harness 20 of the edge of the wire are 20 The direction of the straight portions is not orthogonal. In order to maintain the opposite direction of the connector 25 or the ground bar 26 and the straight portion, the respective bundles from the respective cables 24 can be adjusted to the aforementioned f \ %; The length of 24. At one end of a coaxial cable harness 20, the coaxial cable 24 is divided into a plurality of groups, when the groups 25 are mounted with the connector 25 or the ground rod 26, or the coaxial cable harness 20 is further bundled into a bundle of the plurality of coaxial cables 24, and each The same applies to the harness to mount the connector 25 or the ground rod 26. In the above-described embodiment, the portions other than the end portions 21a and 2 1b of the coaxial cable harness 20 are bundled with the binding tape 23, but the form of the bundled coaxial cable 24 is not limited thereto. Each of the coaxial cables 24 集 may be bundled without covering the entire body, and only when the substrates 11 and 12 are slid, the shape of the harness may be maintained to be partially bundled. When the substrates 1 1 and 12 are slid, the coaxial cable 24 and the substrates 11 and 12 and the portions of the substrates 11 and 12 which are in contact with each other are preferably taped or the like to improve the durability against friction. Further, the binding tape 23 may be bonded to the coaxial cable 24 with splicability, or may be non-joining. However, when the coaxial cable 24 slides on the binding tape and bends in the longitudinal direction during bending, the bending load is easily released. Therefore, it should be non-joining. The coaxial cable harness 20 is connected to the upper and lower substrates 11 and 12, and the overlap between the two bases 20-200816882 plates 11 and 12 is the maximum position (the state of FIG. 2) until the overlap of the two substrates 1 1 and 12 is the smallest. At the position (the state of Fig. 1), the two substrates 11 and 12 are repeatedly slid back and forth to investigate the relationship between the number of times of sliding back (hereinafter referred to as the number of times of sliding) and the disconnection of the center conductor of the coaxial cable 24. As a result, it is understood that when the coaxial cable 24 is not bundled in the vicinity of the bending starting point of the coaxial cable 24 (the boundary point between the U-shaped straight portion and the curved portion), the number of slips before the disconnection is greatly improved. It is known from the experiment that the starting point of the bending is sandwiched between the two sides of the 3mm range, and the bundles of different shaft cables 24 are bundled, and it is better to have a bundle of 24 mm on both sides and 24 bundles of different shaft cables. The reason for this is considered as follows: When the coaxial cable harness 20 is bent, a difference in length between the inner side and the outer side of the bent portion occurs. At this time, when the coaxial cables 24 are freely movable, the inner coaxial cable 24 is loosened to absorb the difference in length. However, when the coaxial cable 24 is bundled by a tape or the like, the coaxial cables 24 are restrained from moving or moving, and the difference in length cannot be absorbed, and bending stress is applied to the coaxial cable 24 at both ends of the bent portion. That is, the bending (/load is easily concentrated on the bending starting point of the coaxial cable 24 (the boundary point between the straight portion of the U-shape and the curved portion). The substrate 1 1 and 1 2 are continuously slid, and the load is concentrated by the bending stress. The portion is considered to cause the central conductor of the coaxial cable 24 to be broken. Therefore, the portion where the bending stress is likely to occur, that is, the vicinity of the bending starting point, the coaxial cable 24 is not suitable for bundling without being restrained. Since the mobile phone is usually in the upper and lower frames. One of the closed state (shortened state) or the open state (extended state), therefore, the substrates η, 12 used by the mobile phone 30 or the like are usually at the both end portions 21a, 21b of the coaxial cable harness 20 The closest state or the farthest state. -21- 200816882 This state is shown in Fig. 1 3, which is the closest state to both ends 2 1 a, 2 1 b of the coaxial cable harness 20, or as As shown in Fig. 14, the both end portions 21a, 21b of the coaxial cable harness 20 are one of the farthest from each other. Therefore, as shown in Fig. 13 or Fig. 14, the bending starting points A, B at the U-shape are shown. Nearby, if not bundled When the shaft cable 24 is used, it is hardly subjected to the bending stress, and the mechanical characteristics (the number of times of sliding before the disconnection) corresponding to the bending of the coaxial cable harness 20 can be greatly improved. If the coaxial cable 24 of the AWG 42 to 46 is used, the coaxial cable is formed. In the case of the wire harness 20, when the entire length 22 is bundled by the binding tape 23, when the sliding of the substrates 1 1 and 12 is performed 50,000 times, the center conductor of the coaxial cable 24 is broken. The range in which the coaxial cable 24 is not bundled is set. In the case of a range of 3 mm on both sides in the longitudinal direction with respect to the bending starting points A and B of the U-shape, even if the sliding of the substrates 1 1 and 12 is performed 100,000 times, the center conductor of the coaxial cable 24 is not broken and will not be bundled. When the range is set to be 5 mm on both sides in the longitudinal direction with respect to the bending origins A and B, even if the sliding of the substrates 1 1 and 1 2 is performed 15,000 times, the center conductor of the coaxial cable 24 is not broken. In order to maintain the shape of the harness of the coaxial cable harness 20, in a state shown in Figs. 1 and 4, a part of the curved portion of the U-shape is preferably bundled by the binding tape 23 or the like. The form in which the vicinity is not bundled also includes the case where the connector is attached to the end of the coaxial cable harness 20 and the case where it is directly mounted on the substrate. Furthermore, the coaxial cable 24 included in the end portion of the coaxial cable harness 20 is divided into several groups. In the case where the connectors are installed or the ground rods are installed in each group, the wiring harness of the plurality of coaxial cables 24 is further bundled, and becomes the same as the cable harness 20 of the -22-200816882. In addition, as shown in FIG. As shown, when the coaxial cable 24 is bundled intermittently at a plurality of places, since the portion where the bundle is not bundled is intermittently disposed at the plurality of portions, the bending load applied to the coaxial cable 24 can be easily released as a whole, regardless of the coaxial cable 24 The position of the bend prevents damage to the coaxial cable 24. Further, by intermittently bundling the coaxial cable 24, both the end portions 21a and 21b of the coaxial cable harness 20 are in the closest state and the farthest state, and it is easy to realize the form in the vicinity of the starting point of the bundle bending. In order to maintain the shape of the harness, each of the coaxial cables 24 only needs to be bundled intermittently without being scattered. As described above, since it is only necessary to bundle at a range of 3 mm across the starting point of the bending, the interval at the time of intermittent bundling is preferably 6 mm or more. Further, it is more preferable to intermittently bundle at intervals of 10 mm or more. Fig. 9 shows a form in which the binding tape 23 is bundled. However, it may be bundled by a wire or may be integrated by dropping the bonding agent. Further, as shown in Fig. 15 and Fig. 16, the coaxial cable 24 may be wound by a banding tape 23 (see Fig. 15) or a line 27 (see Fig. 16) in a spiral shape so as to be bundled. The coaxial cable harness 20 of Figs. 15 and 16 is capable of easily releasing the bending load applied to the coaxial cable 24 as a whole in the same manner as the configuration of the plurality of bundles intermittently shown in Fig. 9. Further, the both ends of the portion where the tying tape 23 or the wire 27 is spirally wound may be bundled in advance by the tying adhesive tape 23 so as not to cause entanglement. Further, as shown in Fig. 17, the coaxial cable 24 may be bundled with a gap by a spiral tape 28 which has been memorized in a cylindrical shape. The spiral tape -23-200816882-shaped tape 28 can be used in which the band-shaped binding tape 23 is used in a cylindrical shape and has been stored in a shape, or a spiral groove is formed in a cylindrical member. If the rubber hose is cut into a spiral shape. The coaxial cable harness 20 of Fig. 17 can easily release the bending load applied to the coaxial cable 24 as a whole, similarly to the configuration in which the bundles are intermittently stacked at a plurality of points as shown in Fig. 9. Further, since the spiral tape 28 has been memorized in a tubular shape, it is easy to maintain the state of the bundled coaxial cable 24. At the time of bundling, it is also a case where the tape or the hose which has been memorized in shape is coated on the coaxial cable 24, and the work efficiency is higher than that of wrapping the tape or the wire at a specific distance. Further, as shown in Fig. 18, the bundled coaxial cable 24 can also be covered by the tubular braided sleeve 29. The braided sleeve 29 can be used, for example, by braiding a metal foil wire or a chemical fiber into a tubular shape. The coaxial cable harness 20 of Fig. 18 does not engage the coaxial cable 24 as the bonding tape, and the coaxial cable 24 can be bundled in a state where it is easy to move in the longitudinal direction. Further, when the sleeve itself is formed into a flat shape, as shown in Fig. 3(C), the portion of the bundle can be easily flattened, and the accommodation space can be reduced. When the coaxial cable 24 is bundled into a circular shape having a diameter of 1.9 mm, the outer diameter is 2.3 mm, and when the outer diameter is 2.3 mm, when it is pressed and flattened, the height is 1.8 mm and the width is 2.6 mm. . Further, when the coaxial cable 24 is bundled into a circular cross-section having a diameter of 1.9 mm, the outer diameter is 2.1 mm when the braided sleeve 29 is covered, and when it is pressed flat to have a height of 1.3 mm, the width is set to be 1.3 mm. It is 2.8mm. Fig. 9 and Fig. 15 to Fig. 18 show that the direction of the longitudinal direction of the connector 25 is parallel to the longitudinal direction of the coaxial cable 24 (the direction along the straight portion of the U-shape), that is, the coaxial cable at the end. 24 bending 90 degrees. In the case of the above, the length of each of the coaxial cables 24 is different, and the length of each of the coaxial cables 24 from the bundle to the connector 25 is adjusted from -24 to 200816882. Further, the direction of the connector 25 is not limited to the above. The length direction of the connector 25 may also be orthogonal to the longitudinal direction of the coaxial cable 24. The connector is not attached to the end, and the grounding rod is mounted, and the coaxial cable harness 20 directly mounted on the substrate is also the same as when the connector of the hub of each coaxial cable 24 is mounted. Further, the above embodiments can be combined as appropriate. For example, the connector 25 may be attached to one end portion 21a of the coaxial cable harness 20 to be connected to the substrate 1 1, and the other end portion 2 1 b may be directly attached to the substrate 12. Further, as shown in FIGS. 11 and 12, the direction of the coaxial cable 24 at the joint portion may be appropriately different from the direction of the straight portion of the U-shape of the coaxial cable harness 20, and is a picture of FIG. 9 and FIG. The form of the various bundles shown in Fig. 18. [Industrial Applicability] As described above, the present invention can be used as a coaxial cable splicing structure in which two substrates which are slidably coupled and which are coaxially connected by a coaxial cable On mobile phones, etc. The present invention has been described in detail above with reference to the specific embodiments thereof, and it is understood that various changes and modifications may be made without departing from the spirit and scope of the invention.
