參照圖式說明用以實施本發明之光連接器用套接管、 光連接器及光連接器之製造方法之較佳態樣。 第1圖係顯示實施態樣之光連接器用套接管100其構造 之立體圖。第2圖係顯示光連接器用套接管100其各部位之 5 構造及組裝時之狀態的立體圖。第3圖係顯示使用光連接器 用套接管100之光連接器110組裝時之狀態的立體圖。第4圖 係顯示光連接器110之構造的平面圖。第5圖係顯示光連接 為110之B — B截面圖。 如第1圖、第2圖所示，光連接器用套接管100，係由前 10區塊10、後區塊2〇、補強構件30、及作為薄膜狀之折射率 整合劑之折射率整合膜F而構成。 如第3圖所示，於光連接器110使用套接管1〇〇,而該套 接苢100係收谷中繼用光纖之前區塊、及具光纖插入部Μ 及溝部24之後區塊20接著而成者。 15 連接光纖配線時，係讓無導銷之光連接器110與附導銷 之對向側光連接器，經導銷而相互對位再加以連接。 如此’經由導銷進行及解除連接器的連接時，雖前區 塊10與後區塊20之連接面接受一插入拔出負荷，但可藉由 设置補強構件30，防止因插入拔出負荷而讓前區塊1〇與後 20區塊20之連接面剝離。 如第1圖、第2圖所示，前區塊1〇係位於光連接器用套 接官100之$側’且譬如以充填有無機填充物之樹脂材料而 成形。樹脂材料係熱硬化性環氧樹脂、pps(聚苯硫醚）等。 又，無機填充物係使用譬如粒狀二氧化矽。填充量為3〇% 13 200839338 〜95%之範圍。 前區塊10係中央部分設有多數收容光纖1之收容部 11 ’而讓前區塊10位於後區塊20之插入部23的同軸線上， 又’前區塊10在中央部分，以於該收容部11兩侧與收容部 5 11平行，且讓前區塊10位於後區塊20之導銷孔22的同軸線 上方式而設置導銷孔12。 再者，於前區塊10連接後區塊20之側的兩側端上，設 有作為用以安裝補強構件3〇之安裝部其中一部分的切口部 13 °進行補強時，該切口部13上配置有補強構件30其中一 10 部分。 又，收容部11係多數貫通孔。且導銷孔12其中一端上 形成有凹部15。 又’切口部13係於前區塊10連接後區塊2〇之側的兩側 立而上’預先成形為口字形狀。切口部13之深度係對應於補 15強構件30之厚度，且補強構件30並未突出超過光連接器用 套接管100之外形尺寸，而以可維持JIS規格所規定的外形 尺寸來加以設計。 譬如，補強構件30之厚度為〇.lmm時，切口部13之深 度為0.15mm。如此，可確保接著劑塗佈層及尺寸之誤差等 2〇所需之餘裕。且令切口部丨3其長向方向的幅寬為W1。 再者，此例中，收容部丨丨係形成為一列，但並不限於 此。亦可為譬如二列以上。 後區塊20係位於光連接器用套接管1〇〇之後侧，且譬如 以柄J曰成形。後區塊20係於中央部分的後端部，較大地開 14 200839338 有一套件口 21，而中央部分的前端部，係與套件口 21連通 且設置多數插入部23及溝部24，又，方形的短邊方向之側 部部分，其中一側係開有與插入部23連通之窗部21A，而方 形的長邊方向之側部部分中，兩側之前後方向上，係設有 5 導銷孔22。 此例中，插入部23係對應12芯之光纖的12個通孔，但 並不限於此。亦可少於前區塊10之收容部11。又，亦可對 應前區塊10而讓插入部23為二列以上。且插入部23之通孔 長度可為光纖徑的至少二倍以上。藉此，所插入的光纖係 1〇 可穩定地加以固定。 又，後區塊20係前端面的中央部設置有通溝26。且前 端面之側部設置有接著面28。 由於後區塊20之前端面的中央部上設置有通溝26，而 於插入部23之端面與接著面28之間形成一段差，故可防止 I5 塗佈於接者面28上之接著劑流出而阻礙光路徑。 再者’後區塊20連接前區塊1〇之側(接著面28側的兩側 端）上設置有作為用以安裝補強構件30之安裝部其中一部 分的切口（部）25。進行補強時，該切口部25上係配置有補強 構件30其中一部分。 20 切口部25係預先成形為口字形狀之切口狀。切口狀的 深度係對應於補強構件30之厚度，且補強構件3〇並未突出 超過光連接器用套接管100之外形尺寸，而以可維持jis規 格所規定之外形尺寸來加以設計。 套件口 2!可嵌合方塊形之套件(b〇〇ts)4〇，該套件4〇係 15 200839338 將所連接之光纖芯線2插通後，將其緩衝保持於後區塊2〇 者，又，套件口 21具有占後區塊2〇後側約_半之長方體容 積。插入部23係讓光纖成列地插入者，且形成有位於後側 之C形或V形溝24，前述光纖係剝離經套件4〇而緩衝保持於 5 套件口 21之光纖芯線2其外皮者。 窗部21A係用以將光纖芯線2之光纖，固定於插入部之 熱硬化性、常溫硬化性等之固定用樹脂材4的填充空間，且 具有與位於插入部23後部之溝部24相對向的長方體容積。 導銷孔22係以非連通之狀態而貫通套件口 21、插入部^及 10窗部21A。 又，後區塊20連接前區塊10之側的兩側端上，係設置 有作為用以安裝補強構件30之安裝部其中一部分的切口部 25。進行補強時，該切口部25上係配置有補強構件3〇其中 一部分。前區塊10之切口部13與後區塊2〇之切口部乃，構 15 成補強構件30之安裝部。 再者，插入部23係多數之貫通孔。又，導銷孔“其中 端上係形成有凸部29。該凸部29係可嵌入前區塊1〇所對 應之凹部内，負責進行接著時之定位功能，且可增加接著 ^面積並增強接著強度，進而’可防止接著劑流入導銷孔 U，22。又，位於後區塊20表面上之標誌M，係芯線插入方 向定向標誌。 、固部21A係設置於溝部24之上方。且溝部24在配置有光 栽之場合，係形成為光纖之軸線與插入部23位在同轴線上。 補強構件30係使用不銹鋼板，並形成為由彎曲部 16 200839338 31A，31B與直邊部32所形成的^字形狀。此例中，補強構件 30之厚度為0.1mm。又，此時，係使用兩個補強構件30而 進行補強。又，讓補強構件30其長邊方向之幅寬，僅略小 於切口部13與切口部25之幅寬的合計。藉此，安裝補強構 5件30時，可不對前區塊1〇與後區塊20之連接面造成負荷地 進行安裝。又，為易於進行安裝，補強構件3〇之角部係設 置有堰部R或切部。 10 15 折射率整合膜F與光纖具有折射率整合性，且係具有黏 者性抑或無黏著性者。此例中，係使用具黏著性者。折射 率正合膜F宜為即使由於振動等外部因素而讓光纖之間隔 申鈿仍可藉由黏著力而保持於光纖端面之間。因光纖之 之:係在數程度之範圍内變化，故只要是可對應該範圍 之夂化即可，因此，黏著保持距離宜為5#茁以上。 塊之^ M裝時，薄膜的黏著性為可附著於前區塊或後區 一欠士 X 17可。右黏著性過高，於光纖連接後發生必須再

並使其加以密封化者。而其中，由耐環境性、接著性之面 15觀之，一般宜使用矽系、丙醯基系。又，可藉由交聯劑、 添加劑、軟化劑、黏度調節劑、底層貪劑等’自由地調整 接著力、濡濕性，亦可附加耐水性、财濕性、財熱性專。 再者，因材料、製法等而有多孔構造之態樣，但在光學連 接時，若藉由施加按壓力而加以壓締，7 /肖除二氣且不會 2〇 對光損失造成影響。 接著，參照第3圖〜第5圖，說明有關使用光連接器用 套接管100之光連接器的製造方法。 光連接器110之製造係以下述程序進打。首先’以樹脂 造模出前區塊10與後區塊20。進行造模時’分別形成作為 18 200839338 安裝部之切口部13及切口部25。 其次，將中繼用光纖1插入(依需求而使用接著劑）前區 塊10之收容部11内而加以收容後，對前區塊10之前端面及 後端面，與中繼用光纖1之前後側的端面共同進行研磨产 5理。 处 接著，將折射率整合膜F貼附配置於後區塊2〇之通溝 26(參照第3圖）。 再者，將組裝用導銷22A插入後區塊20之導銷孔22，並 於接著面28上塗佈接著劑，且經由直徑699.〇//111自7〇1.〇“ 1〇 m之組I用導銷22A進行定位而與前區塊1〇接著。接著劑可 考慮熱硬化環氧、氰丙烯基系等的接著劑。此處，藉由使 用直徑699.0/zm自701.0/zm之組裝用導銷22A而進行定

Moreover, the optical connector 110 uses the optical connector for the socket 1 and the light In the process of the connector, first, the end surface of the front block 10 after receiving the relay optical fiber is subjected to grinding processing together with the end surface of the relay optical fiber 1, and secondly, the refractive index 15 integrated film F is attached and disposed in the rear region. The through groove 26 of the block 20, and then the front block 1〇 and the rear block 20, the reinforcing member 30 is mounted and fixed by an adhesive, and further, the optical fiber inserted into the rear block 20 is fixed by an adhesive. The optical fiber in the hole 41. Therefore, it is not necessary to inject the integrator twice after fixing the front block and the rear block as in the prior art, thereby suppressing the outflow of the integrator at the time of injection or after injection. In particular, in a warm environment, it is possible to suppress the integrator from flowing out of the connector and by arranging a film-like refractive index integrator, it is possible to reduce the difficulty of the conventional work and the integrator injection process which is difficult in the quality pipe. 20 200839338 The device is also made up of the assembly work towel that is set in the joint ferrule, and the adhesive is heat-hardened. 'The pure fineness of the optical connector makes the fluidity increase. . The agent flows out to the light 5 10 15 Furthermore, after the front block and the back block, the fiber is inserted from the back. The multi-core ribbon fiber is precision-cut and is inserted into the through-hole by means of elastic deformation to absorb the front end == to the refractive conversion film. The money can be really high! , by using 5//m~15G/Zm thin braided refractive index integration sheet! The optical characteristics are maintained in the connection faces of the fibers of the block and the rear block. In addition, the film-like refractive index integration of the adhesive is used for adhesive bonding, whereby the film-like refractive index integrated agent can be attached to the rear block in the case of the front block and the back block. On the surface of the channel. This improves workability. Further, the depth of the groove is the same as the thickness of the film-like refractive index integrator, or is shallower than the thickness of the film-like refractive index integrator, whereby the film-like refractive index can be stably maintained. Integrator. Further, since it is easy to carry the refractive index integrator, it is not necessary to provide a slope at the upper or lower portion of the through groove 26 as is conventional. Further, it is not necessary to form a slit between the end surface of the insertion portion 23 of the rear block 20 and the adhesion surface 28, since it is not necessary to flow out the adhesive applied to the adhesion surface 28 to block the light path. The difference is the segment. Therefore, the configuration is simple and the manufacturing cost can be reduced. 21 200839338 In the case of the embodiment of the invention, the method of attaching the refractive index integrated film F to the through-groove 26 of the rear block 2 is described, but the method is not limited thereto.
