參閱圖2至圖4,該適配器1具有一殼體11、沿一前後方向D1(箭頭指向前方,反向為後方)形成於該殼體11內近後端處且沿一左右方向D2(箭頭指向右方,反向為左方)間隔並排的兩個插芯通道12、對應於該兩插芯通道12的後端部且自所述殼體11朝後延伸的兩個連接套筒13,以及由前往後地形成於該殼體11的前側面且分別對應於該兩插芯通道12的兩個插槽10。該兩個插槽10供該光纖連接器200插入,且該兩插芯通道12的前端部分別伸入該兩插槽10內。每一連接套筒13具有位於左右兩側且由後朝前形成的兩個側開槽131,以及被該兩側開槽131沿一上下方向D3(箭頭指向上方,反向為下方)間隔開的兩個保持段132。需要說明的是,所述插芯通道12、所述連接套筒13及插槽10的數量可以依照需求做調整,其可以各為一個或三個以上,不以本第一實施例中的數量作為限制。2 to 4, the
該兩光纖接頭2分別設於該兩連接套筒13,每一光纖接頭2包括適用於設置光纖F1的一插芯21(ferrule),以及設於該插芯21的一保持件22。該插芯21沿該前後方向D1經由對應的連接套筒13對應地插設於對應的插芯通道12的後端部。該保持件22具有套設於該插芯21的後端部且容置所述光纖F1的一管體221,以及凸出且環繞地形成於的外側面的一凸緣222。該保持件22插設於對應的連接套筒13且該凸緣222被保持於該兩保持段132之間。在本第一實施例中,每一連接套筒13的每一保持段132具有形成於內壁面且上下貫穿的一保持孔132a,該保持孔132a對應容置所述光纖接頭2的凸緣222。該凸緣222的橫截面呈多邊形且具有間隔排列的多個角緣部222a、位於該凸緣222後端的一肩部222b(該肩部222b也位於該等角緣部222a後端),以及位於該凸緣222前端且朝前地漸縮的一漸縮部222c。該保持孔132a對應容置所述光纖接頭2的凸緣222的其中一角緣部222a,該肩部222b對應所述保持孔132a的位於後端的內壁面且被所述內壁面所限位,以防止所述光纖接頭2的凸緣222朝後地脫離所述連接套筒13。並且,每一連接套筒13還具有自該插芯通道12的後端朝後地漸擴且對應容置所述凸緣222的漸縮部222c的一推拔部133。在本第一實施例中,該推拔部133的上部分與下部分是分別是形成於該連接套筒13的該兩保持段132。在光纖接頭2組裝於連接套筒13時,通過凸緣222前端的漸縮部222c能夠順勢及順力的先將連接套筒13的兩個保持段132張開,直到凸緣222的角緣部222a進入對應的保持孔132a內後兩個保持段132復位,該肩部222b對應所述保持孔132a的位於後端的內壁面且被所述內壁面所限位,而連接套筒13內的推拔部133能夠導引插芯21朝向插芯通道12插入,以完成光纖接頭2與連接套筒13的組裝。The two fiber
參閱圖2至圖3及圖5至圖6,該兩獨立的固定套筒3套設地組裝在該兩連接套筒13外。每一連接套筒13的每一保持段132還具有位於後端處且朝外形成的一外凸緣132b,在本第一實施例中,位於上方的保持段132是朝上地形成該外凸緣132b,位於下方的保持段132是朝下地形成該外凸緣132b,每一外凸緣132b的前端面構成一擋止部132c。每一固定套筒3具有在朝後的方向被位於該兩保持段132的擋止部132c擋止且在上下方向D3分別佈設的兩個彈性扣件31,以及在朝後的方向上擋止所述光纖接頭2的凸緣222的肩部222b且在左右方向D2分別佈設的兩個擋塊32,該兩擋塊32在本第一實施例中是形成於所述固定套筒3的內壁面。獨立的所述固定套筒3能夠以直接滑入式的套設、扣接、組裝在所述連接套筒13,操作容易簡單。套設地組裝在該兩連接套筒13外的該兩固定套筒3限制了所述連接套筒13的兩個保持段132之間的距離,防止所述連接套筒13的兩個保持段132張開,以使所述光纖接頭2的凸緣222被保持於該連接套筒13的該兩保持段132的保持孔132a內,且藉由在朝後的方向上擋止所述光纖接頭2的凸緣222的所述固定套筒3的擋塊32,以確實地共同防止所述光纖接頭2自所述連接套筒13朝後脫離。Referring to FIGS. 2 to 3 and 5 to 6, the two
需要說明的是,如圖所示的,擋止部132c是延伸到保持孔132a內,所以在其他實施態樣中所述連接套筒13也可以不形成有所述外凸緣132b,此時所述擋止部132c可以是形成於保持孔132a位於後端的內壁面;在另一變化實施例中,可以在保持孔132a後方另外設置一卡合孔用以容置彈性扣件31,擋止部132c可以是形成於卡合孔的後端的內壁面。另外,所述彈性扣件31具有朝後延伸的彈臂以及形成所述彈臂末端的扣塊。It should be noted that, as shown in the figure, the

參閱圖1至圖2及圖6至圖7,詳細來說,該適配器1還具有對應連接於該兩連接套筒13且朝前延伸地形成於該兩插槽10內並圍繞所述插芯通道12伸入插槽10內之部分的對接套筒14,以及分別位於所述插芯通道12內的對齊套管15。每一對齊套管15設置於對應的插芯通道12內,且前述光纖接頭2的插芯21的前端容置所述對齊套管15內。該適配器1的該兩插芯通道12的前端供所述光纖連接器200插入。所述光纖連接器200具有形成有容置所述對接套筒14的一對接凹槽201a的一外殼201、適用於設置光纖F2且凸出於該外殼201的對接凹槽201a並用以插入所述對接套筒14內的對齊套管15的一插芯202、套設於該插芯202且位於該外殼201內的一插芯套203、組裝於該外殼201的一外套204,以及設置於該插芯套203與該外套204之間的一施壓彈簧205。所述對齊套管15使所述光纖連接器200的插芯202與所述光纖接頭2的插芯21相互對準,且該施壓彈簧205將該插芯202與該插芯套203朝所述對齊套管15內施壓推頂,以使所述光纖連接器200的插芯202壓靠所述光纖接頭2的插芯21,以確保所述光纖連接器200的光纖F2與所述光纖接頭2的光纖F1之間的光訊號傳遞。1 to 2 and 6 to 7, in detail, the
參閱圖8,本發明光纖連接組件100之一第二實施例與該第一實施例的不同之處在於,每一固定套筒3還具有連接於該側開縫34的上下兩壁面之間的一連接柱35,通過連接柱35能加強該固定套筒3之結構強度,且使所述固定套筒3能更穩固地組裝設置於所述連接套筒13。當需要拆卸固定套筒3時,可以剪斷連接柱35使固定套筒3能夠自連接套筒13及光纖F1拆離。Referring to FIG. 8, the difference between the second embodiment of the optical
綜上所述,本發明中獨立的所述固定套筒3能夠以直接滑入式的套設、扣接、組裝在所述連接套筒13,操作容易簡單。藉由所述固定套筒3套設在所述連接套筒13外,能確實地限制所述連接套筒13的兩個保持段132的之間的距離以防止兩個保持段132張開,確實地防止所述光纖接頭2自所述連接套筒13朝後脫離。並且,固定套筒3能夠把沒有完全到達定位的光纖接頭2推至定位。In summary, in the present invention, the
惟以上所述者,僅為本發明之實施例而已,當不能以此限定本發明實施之範圍,凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
