Description

光纖連接器
本發明係關於一種光纖連接器，尤其指一種具有透鏡之光纖連接器。
現有光纖連接器一般包括塑膠本體、與塑膠體一體成型的透鏡及固定於本體內的光纖，透鏡位於塑膠本體前端，而光纖自塑膠本體的後端***塑膠本體內的細長孔以鄰近且對準上述透鏡，如此可完成光信號的傳輸，美國專利第4,534,616號及第6,736,550號均揭示了這樣的光纖連接器。惟，在目前大量生產及成本不斷降低之現實情況下，研發人員針對該等光纖連接器不斷研究，希望在現有的技術及產品上做出更節省成本的結構設計。
本發明的目的在於提供一種降低成本的光纖連接器。
為了實現上述目的，本創作採用的一種技術方案：一種光纖連接器，其包括透鏡、本體及光纖，透鏡之前端具有弧形前端面的光穿透部，本體係組裝於透鏡的後端面，該本體具有與光穿透部對齊的細長孔，光纖係收容於該細長孔內中。
相較先前技術，本創作之分開成型的本體可採用低價格材料製成 ，可節省光纖連接器的成本。

第五圖係第二實施例的光纖連接器的立體圖；第六圖係第二實施例的光纖連接器另一角度的立體圖，其中扣持臂向內變形。
下面結合圖面詳細描述本發明。
本發明揭示了兩個實施例。第一圖至第四圖顯示了第一實施例之光纖連接器100，第五圖至第六圖顯示了第二實施例之光纖連接器200。
參閱第一圖至第四圖所示，光纖連接器100包括組裝於一起的透鏡1及基部2。透鏡1係由高導光材料製成(價格較貴)，其前端面設有向前突出的兩對成圓弧突面的光穿透部10，在光穿透部10的兩外側則分別向前突設有導引柱11，該導引柱11較光穿透部10向前突伸。透鏡1的後端面101呈平面狀，在大致對應導引柱11的位置，該後端面101向後延伸出圓柱定位柱12，兩定位柱之間設有細孔13。本體2係由價格較便宜的LPC等塑膠材料一體成型，其前 端面201係平面，用以跟透鏡1的後端面101相互抵接。本體2設有自前端面201向後凹陷的兩定位口22，該定位口22係貫穿本體的上下表面及前端面201，具有左右相對的內側面221、222，內側面221位於相對內側且為垂直面，另一內側面222位於外側且由兩相交的平面組成，透鏡1的定位柱12***該定位口22而將透鏡1及本體2組合於一起，兩者固定的方式可以為膠合、干涉或其他方式；當然，也可將定位柱12設置在本體2上而將定位口相對的設置在透鏡的後端面101上。分開成型的本體與透鏡也有助於對透鏡製造公差的控制。兩定位口22的內側設有向後貫穿的細長孔21，該等細長孔與透鏡的細孔13及光穿透部10對齊，用以收容光纖6(第一、二圖中僅顯示一根，本實施例具有4根光纖)，來完成光信號的傳輸。本體2設有分別貫穿上下表面的通孔23a、23b，該等通孔係在利用模仁對靠方法行成細長孔21時供模仁的退出。
本體2的兩側設有兩扣持臂24，該兩扣持臂前端連接於本體2，後端則與本體2間隔一定距離，扣持臂24的外側面240設有兩向外突出的扣持部241、242，第一扣持部241具有向後的扣持面，第二扣持部242具有向前的扣持面且與第一扣持部241的扣持面間隔一定距離。本體的後端面的中間向後延伸有一柱狀部。
請參閱第五圖及第六圖，光纖連接器200之透鏡31與本體32係一體成型，當然該連接器亦可參照第一實施例的結構由兩部分形成(於此不再贅述)。該光纖連接器200的本體32兩側設有向後延伸且超出本體後端面321的扣持臂4，扣持臂4的外側面41設有向外突出的兩扣持部42、43，第一扣持部42位於前端，且具有面朝前 的導引面422及與導引面成一定角度且面朝後的扣持面421；第二扣持部具有面朝前的扣持面431，第二扣持部的扣持面431與側面41的角度Q小於90度。該光纖連接器係組裝於外部連接器(未圖示)中，該扣持臂用於將光纖連接器鎖扣在外部連接器中，小於90度的第二扣持面有助於光纖連接器拔出時較不容易鬆脫。
綜上所述，本創作確已符合發明專利之要件，爰依法提出申請專利。惟，以上所述者僅係本發明之較佳實施方式，本發明之範圍並不以上述實施方式為限，舉凡熟習本案技藝之人士援依本發明之精神所作之等效修飾或變化，皆應涵蓋於以下申請專利範圍內。
