Description

光纖耦合器
本發明是涉及一種光纖連接器,尤其涉及一種光纖耦合器。
光纖耦合器用於實現光纖之間之對接,習知之光纖耦合器一般包括本體,該本體包括耦合件、複數傳輸透鏡及複數傳輸光纖,該複數傳輸透鏡安裝於該耦合件上,且部分凸設於該耦合件,該複數傳輸光纖裝設於該耦合件上,且與該透傳輸鏡耦合設置。由於光纖耦合器之傳輸透鏡凸露於耦合件外,傳輸透鏡處於暴露狀態。是故,傳輸透鏡容易被外部環境污染,造成光信號能量之損耗,降低光傳輸效率。
鑒於以上內容,有必要提供一種能夠防止光纖耦合器之透鏡被污染之光纖耦合器。
一種光纖耦合器,其包括本體,該本體包括耦合件、透鏡、光纖及連接柱,該透鏡與該光纖安裝於該耦合件上,且該透鏡部分凸出於該本體,該光纖之末端與該透鏡耦合,該連接柱凸設於該耦合件上,且該連接柱與該透鏡鄰近設置。該光纖耦合器還包括與該本體拆卸配合之蓋體,該蓋體包括一基體,該基體上開設有與連接柱配合之定位孔及容納透鏡凸出於該本體外之部分之收容孔。
上述光纖耦合器,採用相配合之本體與蓋體,本體之耦合件上設有連接柱,透鏡安裝於耦合件上,且部分凸出於耦合件外。蓋體之基體上開設有並別設置定位孔與收容孔。連接柱分別卡入於定位孔內,且透鏡收容於收容孔內。由於透鏡收容於蓋體之收容孔內,是故避免了透鏡被外部環境污染或碰傷。

下面將結合附圖及具體實施方式對本發明之光纖耦合器進一步之詳細說明。
請參閱圖1,本發明實施方式之光纖耦合器100包括本體10及與本體10可拆卸配合之蓋體30。
請同時參閱圖2及圖4,本體10包括耦合件11、二連接柱13、二透鏡17、複數光纖18及定位蓋19。耦合件11大致呈矩形板狀,其包括第一安裝面111及與第一安裝面111與垂直設置之第二安裝面113。第一安裝面111上有間隔之開設有二容納槽1113,用以安裝二透鏡17。第二安裝面113上凹設有大致為U形之安裝槽1131,用以安裝光纖18,其中U形安裝槽1131之兩凸出部分別朝向對應之容納槽1113。
二連接柱13由耦合件11之第一安裝面111之二端部向同一側延伸 形成,且容納槽1113設置於二連接柱13之間。連接柱13與第一安裝面111垂直設置,連接柱13呈圓臺狀,其直徑朝遠離第一安裝面111方向逐漸減小。二透鏡17分別裝設於二容納槽1113內,且部分凸出於容納槽1113外並與蓋體30相對。光纖18裝設於第二安裝面113之安裝槽1131內,且光纖18之一末端穿過安裝槽1131與透鏡17耦合進行信號傳輸。
定位蓋19之形狀與耦合件11之安裝槽1131相匹配。定位蓋19之底壁兩側上開設有與光纖18相匹配之定位槽191,使光纖18定位於定位蓋19與耦合件11之間。
可理解,定位蓋19可以省略,將光纖18穿設於耦合件11上即可。
可理解,容納槽1113之數至少為二,透鏡17之數至少為二,該至少二透鏡17分別收容於該至少二容納槽1113內。光纖18數至少為一根,且光纖18與透鏡17耦合。
請同時參閱圖3,蓋體30呈矩形板狀,其設置於耦合件11之第一安裝面111上。蓋體30包括一基體31,基體31包括一連接面311,連接面311與耦合件11之第一安裝面111相對。連接面311上開設有並列設置之二定位孔3111及一收容孔3113,且收容孔3113位於二定位孔3111之間。二定位孔3111與耦合件11之二連接柱13分別相對應,用於與連接柱13定位配合,以使耦合件11與蓋體30準確定位連接。定位孔3111之孔徑沿遠離連接面311之方向逐漸減小。收容孔3113與耦合件11之二透鏡17相對,用以收容二透鏡17。
本實施方式之光纖耦合器100採用相配合之本體10與蓋體30,耦合件11之第一安裝面111上設有二連接柱13及二容納槽1113,二 容納槽1113設置於二連接柱13之間。二透鏡17分別安裝於二容納槽1113內,且其部分凸出於容納槽1113。蓋體30之連接面311上設有並別設置之二定位孔3111與一收容孔3113。本體10之二連接柱13分別卡入二定位孔3111內,且二透鏡17收容於收容孔3113內。由於二透鏡17收容於蓋體30之收容孔3113內,是故避免了光纖耦合器100之透鏡17於運送過程中被外部環境污染或碰傷。
綜上所述,本發明確已符合發明專利之要件,遂依法提出專利申請。惟,以上該者僅為本發明之較佳實施方式,自不能以此限制本案之申請專利範圍。舉凡熟悉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。
