Description of the Invention [Technical Field] The present invention relates to an optical connector in which optical fibers are connected to each other. [Prior Art] A conventional optical connector includes a ferrule, a mechanical joint, and a main connector housing (JP-A-2005-140989). The ferrule is cylindrical. A short fiber (bare fiber) is held in the ferrule system. The short optical fiber is fixed to the ferrule by an adhesive or the like. The front end of the ferrule is honed. The mechanical joint is provided with a base portion fixed to the rear end surface of the ferrule, a pressure control portion provided at the base portion, and two holding members that sandwich the base portion and the pressing portion. A fiber groove is formed in the base portion. An extension of the short fiber from the socket is disposed in the fiber trench. The front end of the fiber is also placed in the fiber trench. The end face of the front end of the fiber is overlapped at the rear end face of the short fiber. The pressing portion is configured to cover the front end portion of the optical fiber and the short optical fiber. The clamping member is a U-shaped elastomer. The base portion and the pressing portion are sandwiched by the holding member, whereby the optical fiber and the short optical fiber are fixed. A groove portion is formed in the base portion and the pressing portion to form two slits for inserting a wedge which is pressed between the base portion and the pressing portion. The ferrule and the mechanical joint are housed in a main connector housing having a generally rectangular cross section. The front end portion of the ferrule protrudes only from the front end surface of the main connector housing. Under the main connector housing, there are two long holes for the mechanical joint to be exposed for -4-200916866. Between the main connector housing and the mechanical joint, a spring that pushes the mechanical contact to the front side of the main connector housing is disposed. The connection between the optical fiber of this optical connector and the short optical fiber is as follows. First, the wedge is placed in the slit through the long hole of the main connector housing, and the elastic force against the clamping member presses between the base portion and the pressing portion. Next, in this state, the leading end portion of the optical fiber and the short optical fiber are respectively inserted into the optical fiber grooves of the base portion. Then, pull the wedge out of the slit. As a result, the base member and the pressing portion are brought into contact with each other by the holding member. Through the above operation, the front end portion of the optical fiber and the end surface of the short optical fiber overlap each other in the optical fiber groove, and the optical fiber and the short optical fiber are optically connected. [Problem to be Solved by the Invention] In the conventional optical connector, 'in order to connect the short optical fiber and the optical fiber, the wedge is inserted into the slit against the elastic force of the clamping member. After the base member and the pressing member are pressed, the short fiber and the tip end portion of the optical fiber are inserted into the fiber groove, and the wedge that is firmly held by the base member and the pressing member must be removed. Therefore, the connection between the short optical fiber and the optical fiber in the conventional optical connector is troublesome. The present invention has been made in view of such circumstances, and an object of the invention is to provide an optical connector capable of easily connecting a relay optical fiber supported by a ferrule to an optical fiber connected to -5-200916866. [Means for Solving the Problem] In the first aspect of the present invention, the present invention includes: a casing; and a center fiber housed at one end of the casing; and one end of the relay fiber a ferrule that is provided at one end of the outer casing while being movable in a pulling direction: a sleeve that accommodates the outer casing and combines the other end of the relay optical fiber with the front end portion of the one of the optical fibers; And a front end portion that is connectable to a casing provided on a front side connector of the other optical fiber; and a direction disposed in the casing toward the front end portion from the one end portion of the casing And an elastic body that presses the socket; and is linearly connected between the optical fiber insertable position at which the one end portion can be inserted and the fixed optical fiber fixing position, and is coupled to the other end portion of the outer casing and the aforementioned When the longitudinal direction of the outer casing is obliquely intersected, when the optical fiber position is moved toward the optical fiber fixing position, the one front end portion is moved to the relay light. a fiber fixing means for fixing the front optical fiber to the outer casing; and the outer casing has a supply hole for supplying both end portions of the sleeve, and the opening and closing member for opening and closing the supply hole is provided at the front end Optical connector. As described above, when the optical fiber fixing means is movably disposed at the other end of the outer casing between the fixed position of the optical fiber insertable fiber, a relay optical fiber is inserted and received and connected to the corresponding socket of the outer casing. The optical fiber of the optical fiber is placed along the side of the insertable optical fiber, and the optical fiber -6 - 200916866 fixing means is straight from the optical fiber insertable position to the fixed position of the optical fiber, and the front end portion of one optical fiber is transferred to the relay. The optical fiber fixes one of the optical fibers to the outer casing. Conversely, when the fixed position of the optical fiber solid fiber moves toward the fiber insertable position, the fixed state of the outer casing fiber is released. Therefore, the connection work to one of the optical fibers can be easily performed. Preferably, the optical fiber fixing means moves the opening and closing member when moving forward, and closes the engagement member to the opening and closing member. Preferably, the opening and closing member is preferably attachable to the outer casing, and the outer casing is provided with a pre-compression space portion for allowing the middle curvature. Preferably, the outer casing is provided with a pre-compression space portion for deflecting the one end portion. Preferably, the cam hole provided with the cam wheel pin engaged at the other end of the outer casing to guide the optical fiber fixing means is a fiber fixing means. Preferably, the optical fiber fixing means is provided with a flat surface that contacts the optical fiber while moving from the forward position to the fixed position of the optical fiber. [Effect of the Invention] According to the invention, it is possible to easily perform the connection work of supporting the optical fiber and the optical fiber connected thereto. When the line moves, the other end, the means of light from one of the optical relay fibers, the way the fiber is fixed to the hole. A pin of a fiber which is followed by a fiber of a fiber, and a relay which is formed by inserting the above-mentioned fiber into the above-mentioned connector.

The cam pins 36, 37 utilize the cam hole 72a, 72b are facing the cross direction
Dc相對性地被引導’滑動件7係可沿著交叉方向Dc滑動 〇 當滑動件7離金屬套筒1 0最遠時’滑動件7係爲浮 出基座3的狀態。此時能輕易地進行往第2光纖收容溝槽 33插入光纖18。此時的滑動件7的位置爲光纖可插入位 置。如果從光纖可插入位置將滑動件7往金屬套筒1 0這 方移動的話，凸輪銷36、37則分別相對式地在孔72a、 72b內移動，凸輪銷36、37係分別被卡止在孔72a、72b 的細頸部分。此時，滑動件7係將光纖1 8按壓於基座3， 將光纖1 8固定在基座3。此時的滑動件7的位置爲光纖固 定位置。 在覆蓋板71的下面71b係形成有光纖按壓部73。在 光纖按壓部73的基座3側係形成有平坦面73a與傾斜面 73b。光纖按押壓部73係嵌合於基座3的中央凹部30，其 平坦面7 3 a係與光纖1 8的包覆部1 8 b (參照第1圖）線接 觸，按壓住光纖18。傾斜面73b係爲大致與交叉方向Dc 平行（參照第9A圖）。 第1 1 A圖係擋門的前視圖，第1 1 B圖係同個擋門的俯 視圖，第1 1 C圖係同個擋門的仰視圖，第1 1 D圖係同個擋 門的側視圖。 如第1 1 A圖〜第1 1 D圖所示，擋門（開閉構件）8係 大致爲長板狀。在擋門8的上面8a係形成有兩個凹部81 -17- 200916866 。又，在擋門8的長方向係分別形成有卡合片82、83。卡 合片82、83的肉厚係比擋門8之卡合片82、83以外的部 分的肉厚還薄。 擋門8係可裝脫地被收容在蓋子5的收容溝槽5 6。把 擋門8對著收容溝槽56裝上或拆下，來開閉蓋子5的供 給孔5 8 b。 因爲擋門（開閉構件）9係爲與擋門8同樣的構造， 所以方便上’於第11A圖〜第11D圖將開閉構件9之各 部的符號劃上括號，予以省略擋門9的說明。擋門9的上 面9a、凹部91、卡合片92、93係分別對應於擋門8的上 面8a、凹部81、卡合片82、83。 擋門9係可滑動地被收容在蓋子5的收容溝槽5 7。擋 門9係在收容溝槽5 7內滑動，來開閉蓋子5的孔5 9 b。 在該實施形態中，作爲擋門8的材料，使用可彈性變 形的樹脂。雖然作爲擋門9的材料不一定是可彈性變形的 材料’但爲了達到與擋門8的共用零件化，因此使用與擋 門8相同的材料。 機械接頭1係利用可通過光纖18的套子（boot) 16 包覆。 其次’關於對該實施形態的光連接器進行光纖1 8的 連接作業做說明。 在連接作業之前’事先組合光連接器。又，除去光纖 1 8之未端部的包覆部〗8 b，讓光纖中心部分1 8 a露出來。 在組裝光連接器的作業，係大致分爲兩個作業。一個 -18- 200916866 是在套殻1 4內組裝套接管1 2及線圏彈簧1 5的作業，另 一個作業是組裝機械接頭1的作業。以下針對該等的作業 做具體地說明。 對於在套殼1 4內組裝套接管1 2及線圈彈簧1 5，是先 通過第2套殼構件142的隔間壁142a的孔142b，將套接 管12的套接管本體ih從第！室142c連通到第2室142d 。此時’套接管1 2的凸緣部1 2 2係抵接於隔間壁1 4 2 a， 或留滯在第1室142c。 其次’在第1套殼構件1 4 1的收容部1 4 1 b配置線圏 彈簧1 5。在此狀態，將第1套殼構件1 4丨插入到第2套殼 構件142的第1室142c。其結果，第1套殼構件141的突 起141f會嵌入到第2套殼構件142的鎖定孔I42e，第1 套殼構件141與第2套殼構件M2就會被結合（參照第 3 C 圖）。 其後，將第1、第2套殼構件141、142插入到第3套 殼構件143。其結果，第2套殼構件142的突起142f會嵌 入到第3套殼構件143的缺口 143a(參照第4圖），第2 套殼構件142就會被卡止在第3套殼構件143。 如以上，組裝到套殼1 4的套接管丨2係只能夠沿著套 接管本體121的長方向，在套殼14內移動預定距離。又 ’套接管本體1 2 1的前端部係藉由線圈彈簧1 5的按壓力 ’從套殼1 4的前端突出。 對於組裝機械接頭1，係先在基座3的套筒收容構件 31收容金屬套筒1〇，接著將蓋子5安裝在基座3，最後將 -19- 200916866 檔門9收容到蓋子5的收容溝槽5 7。此時，將擋門9定位 成蓋子5的供給孔5 9 b不會因擋門9而被塞住。 如以i： ’對於將光纖丨8連接到事先所組裝的光連接 器，係將被保持在套接管12的中繼用光纖17，連通到機 械接頭1的一端側部分3 b的心線收容部3 2 b，插入到第1 光纖收容溝槽3 2。 接著’將機械接頭1的一端側部分3 b插入到1套殼 構件141的插入口 14ld，讓一端側部分3b的突起3e嵌合 到插入口 141d的凹部I41h。突起3e與凹部141h就會嵌 合’當一端側部分3 b的全部被插入到插入口 1 4 1 d時，中 繼用光纖17的端部就會到達金屬套筒的窗孔i〇b。又 ’如果突起3 e嵌合於凹部丨4 1 h的話，機械接頭1的一端 側部分3b就不容易從套殼丨4脫落。 中繼用光纖17的長度係設定成插入到金屬套筒1〇的 中繼用光纖1 7的端部的位置是位在金屬套筒1 〇之窗孔 1 0 b的中央。 其後’通過蓋子5的供給孔5 8b，將所謂凝膠狀的瞬 間接著劑注入到凹部5 8。此時，瞬間接著劑會稍微從供給 孔5 8b溢出。作爲瞬間接著劑，以固化之後還稍具柔軟性 者爲佳。 接著，將擋門8的卡合片82插入到蓋子5的凹部5 8 (參照第7C圖、第1 1圖），將力加諸於擋門8，讓擋門 8大致撓曲成U字狀’在該狀態下，將擋門8的卡合片8 3 插入到第1套殼構件1 4 1的插入孔1 4 1 g，釋放加諸在擋門 -20- 200916866 8的力。其結果’擋門8係因其彈性力而恢復到直直的狀 態’被收容到蓋子5的收容溝槽56。又，凹部58內的瞬 間接著劑係因擋門8而被按壓，流動成圍繞著金屬套筒！ 〇 的一端部’其一部分係流入到心線收容孔1 0a的端部。其 結果，中繼用光纖17係強固地被固定在金屬套筒1〇之一 端部的同時，會避免中繼用光纖1 7直接接觸到心線收容 孔l〇a之一端部的開口緣。 其後，使滑動件7被滑動成沿著交叉方向Dc離開蓋 子5。其結果，基座3的凸輪銷3 6、3 7係在滑動件7的凸 輪孔7 2 a、7 2 b內相對性地移動，頂觸在凸輪孔7 2 a、7 2 b 的一端部，或停住滑動件7此時的滑動件7的位置是在光 纖插入位置（光纖18容易往外殻2插入的位置）。在此 位置，滑動件7成爲浮出基座3之上面的狀態，光纖1 8 變得很容易往第2光纖收容溝槽3 3插入。 接著，將光纖1 8收容到第2光纖收容溝槽3 3的同時 ，將光纖1 8的光纖中心部分1 8a插入到金屬套筒1 0的心 線收容孔l〇a內（參照第3A圖）。 其後，通過蓋子5的供給孔5 9b，將凝膠狀的瞬間接 著劑注入到凹部5 9。此時，瞬間接著劑會稍微從供給孔 59b溢出。 接著，將滑動件7沿著長方向L往蓋子5這方推壓， 如第3 A圖、第3 B圖所示，使滑動件7從光纖插入位置被 移動到第2光纖固定位置（光纖1 8利用滑動件7被固定 在外殼2的位置）。 -21 - 200916866 此時，凸輪銷36、37是於凸輪孔72a、72b相對性地 被引導，滑動件7係往交叉方向沿著Dc移動。由於在移 動途中，滑動件7的光纖按壓部73的平坦面73a，係接觸 於光纖18，因此滑動件7係一邊將光纖18往中繼用光纖 17這方移送一邊移動到光纖固定位置。又，光纖18的光 纖中心部分18a的端部係在形成著金屬套筒10的窗孔10b 的部分，搭接於中繼用光纖1 7的端部，進而使中繼用光 纖1 7的端部往一端側部分3 b這方移動。其結果，中繼用 光纖丨7會在第丨預壓空間32a內撓曲，因其恢復力，光 纖18的光纖中心部分18a會在第2預壓空間33a內撓曲 。又，因爲中繼用光纖1 7的端部與光纖1 8的光纖中心部 分1 8 a的端部是在形成有金屬套筒1 〇的窗孔1 〇 b的部分 搭接，存在於中繼用光纖17的端部與光纖中心部分18a 的端部之間的空氣等係從窗孔1 〇b被排出。 又，中繼用光纖17與光纖中心部分18a的端部彼此 搭接之後的中繼用光纖1 7的端部與光纖中心部分1 8 a的 端部，係往一端側部分3 b這邊移動，離開金屬套筒1 0的 窗孔10b。因此’通過窗孔10b進入到金屬套筒10內的外 部光線無法進入到中繼用光纖1 7的端部與光纖中心部分 1 8 a的端部。 當滑動件7從光纖插入位置移動到光纖固定位置時， 滑動件7會頂觸於擋門9，擋門9會往蓋子5的套筒按壓 部5 3這邊移動。此時，利用擋門9關閉蓋子5的供給孔 5 9b的同時’擋門9的卡合片93會相對性地插入到滑動件 -22- 200916866 7的卡合凹部71g。又，因爲擋門9的卡合片92會潛入到 蓋子5的卡合片53b之下，所以擋門9會被蓋子5與滑動 件7卡止。 當利用擋門9關閉蓋子5的供給孔59b時，凹部59 內的瞬間接著劑係因擋門9而被按壓，流動成圍繞著金屬 套筒1 〇的另一端部，其一部分係流入到心線收容孔1 〇a 的端部。藉此，光纖1 8的光纖中心部分1 8 a係強固地被 固定在金屬套筒10之另一端部的同時，會避免光纖中心 部1 8a直接直觸到心線收容孔1 0a的另一端部的開口緣。 又，被注入到凹部5 8、5 9的瞬間接著劑硬化前，因 爲事先被按壓在中繼用光纖17與光纖18，所以在中繼用 光纖1 7的端部與光纖中心部分1 8 a的端部被強固搭接的 狀態下，接著在金屬套筒1 0。 如果凹部5 8、5 9的接著劑硬化的話，即完成中繼用 光纖17與光纖18的連接。 藉由該實施形態光連接器，達到以下的作用效果。 如上述，當滑動件7能夠在光纖可插入位置與光纖固 定位置之間移動地被設置在外殻2的另一端部，且滑動件 7從光纖可插入位置往光纖固定位置移動時，將一方的光 纖18的前端部移送到中繼用光纖17的另一端部，將一方 的光纖1 8固定在外殻2。相反地，當滑動件7從光纖固定 位置往光纖可插入位置移動時，對外殼2之一方的光纖18 的固定狀態被解除。因而，能夠簡單地進行中繼用光纖1 7 與一方之光纖1 8的連接作業。 -23- 200916866 在以往的光連接器中，當拔掉被插入到基座部與按壓 部之間的楔子時，從光纖溝槽拿起短光纖和光纖的端面’ 短光纖和光纖的端面在導槽內錯開，無法正常的連接短光 纖和光纖。對此，在此實施形態中，並沒有拔掉楔子的作 業，且當滑動件7從光纖可插入位置往光纖固定位置移動 時，因爲滑動件7是構成將光纖18的前端部往中繼用光 纖17的另一端部移送，所以能正確地連接中繼用光纖17 與光纖1 8。 因爲滑動件7的光纖按壓部7 3具有平坦面7 3 a，所以 能藉由平坦面73a強固的按壓光纖18，光纖18就難以脫 落。 因爲中繼用光纖1 7被保持在套接管1 2，所以如果正 確地進行中繼用光纖1 7之長度的調整，儘管利用滑動件7 之光纖18的移送精度提高，還是能夠在形成有金屬套筒 1 0的窗孔1 〇b的部分搭接中繼用光纖1 7的端部與光纖中 心部分1 8 a的端部。因此，因爲滑動件7的尺寸精度能夠 低於習知機械接頭之桿（lever )的尺寸精度，所以能達到 降低成本。 因爲利用蓋子5的供給孔58b、59b對金屬套筒1〇的 兩端部供給接著劑，所以能夠避免中繼用光纖丨7及光纖 中心部分1 8a因接著劑而直接接觸到金屬套筒1 〇的心線 收容孔1 〇a的開口緣。其結果，即使在振動較多之處配置 機械接頭1 ’也能夠顯著的降低中繼用光纖！ 7及光纖中心 部1 8 a因金屬套筒1 〇而損傷的可能性。 -24- 200916866 當蓋子5的供給孔58b、59b因擋門8、9而關閉時， 因爲接著劑被按壓在外殼2內，所以能夠確實地將中繼用 光纖17及光纖18接著於金屬套筒10。 接著劑硬化前，因爲藉由滑動件7事先被按壓在中繼 用光纖17與光纖18，所以在中繼用光纖17與光纖18被 強固搭接的狀態下，將中繼用光纖1 7與光纖1 8接著於金 屬套筒1 〇。其結果能夠防止光之傳送效率下降。 又，因爲在滑動件7係形成有光纖按壓部73，光纖按 壓部73的平坦面73a係與光纖1 8直線接觸，所以滑動件 7能夠強固地保持光纖1 8。 而且，因爲中繼用光纖17與光纖18係接著於金屬套 筒1〇’所以即使拉長光纖18也不容易從外殼2脫落。 又，如果將滑動件7從光纖插入位置移動到光纖固定 位置的話，能夠利用擋門9自動性地關閉蓋子5的供給孔 5 9b ’而且能夠自動性地卡止擋門9。 因爲在基座3的下面設置複數個凹部3 f，因所以能夠 防止成形時的基座3變形，還能削減成型時所需要的電能 及使用材料。 再者，擋門8、9也能夠可旋轉地連結在基座3或蓋 子5。 又’在上述實施形態中，雖是針對單芯用的光纖彼此 連接的光連接器做描述，但也能將本發明應用於多芯用的 光連接器。 再者’在上述實施形態中，雖然在滑動件7的光纖按 -25- 200916866 壓部73係形成有平坦面73b，但光纖按壓部73按壓光纖 1 8的面並不限於平坦面73b，爲了提高保持力也可以是朝 光纖1 8之長方向起伏的波形。 又，在上述實施形態中，雖是將中繼用光纖17及光 纖1 8接著於金屬套筒1 0 ’但在減少強行拉起中繼用光纖 1 7及光纖1 8之虞的情形，或者設置在光連接器振動較少 之處的情形等，也可以不將中繼用光纖1 7及光纖1 8接著 於金屬套筒1 0。 再者’雖然在基座3係形成有第1預壓空間部3 2a， 但也可省略第1預壓空間部32a。 又’在上述實施形態中，雖然開閉構件使用兩個擋門 8、9，但開閉構件一個也可以。 再者，在上述實施形態中’雖使用金屬套筒1 〇，但套 筒的材料並不限於金屬。 又’在上述實施形態中’雖是形成利用突起3 e將外 殼2的一端側部分3b固定在套殼14的插入口 i4ld，但也 可以在一端側部分3 b形成母螺紋，在插入口 1 4丨d形成公 螺紋’利用該母螺紋與公螺紋的螺合而固定，或者使用插 銷等將一端側部分3 b固定在插入口 1 4 1 d。 以上是本發明的最佳形態的說明，該業者很清楚在不 脫離本發明之精神及範圍可做各式各樣的變更。 【圖式簡單說明】 第1圖是由斜上方觀看有關本發明之一實施形態的光 -26- 200916866 連接器的分解立體圖。 第2圖是從另一角度觀看第1圖所示的光連接器的分 解立體圖。 第3A圖是表示第1圖所示的光連接器的中繼用光纖 與一方的光纖連接之前的狀態之側視圖。 第3B圖是表示同個光連接器的中繼用光纖與一方的 光纖連接之後的狀態之側視圖。 第3C圖是表示同個光連接器的中繼用光纖與一方的 光纖連接之後的狀態之俯視圖。 第4圖是水平切斷弟1圖所不的光連接器的第3套殼 構件的圖。 第5 A圖是基座的前視圖。 第5B圖是同個基座的俯視圖。 第5C圖是沿著第5B圖之VC-VC線的剖面圖。 第5 D圖是同個基座的右側視圖。 第6A圖是第2圖所示的基座的立體圖。 第6B圖是表示將同個基座翻過來之狀態的立體圖。 第7A圖是第1圖所示的光連接器的機械接頭的外殼 的蓋子之前視圖。 第7B圖是同個蓋子的俯視圖。 第7C圖是沿著第7B圖之VIIC-VIIC線的剖面圖。 第8A圖是第7圖所示的蓋子的立體圖。 第8B圖是表示將同個蓋子翻過來之狀態的1體圖。 第9A圖是第1圖的光連接器的機械接頭的滑動件之 -27- 200916866 前視圖。 第9B圖是同個滑動件的俯視圖。 第9 C圖是同個滑動件的仰視圖。 第9D圖是沿著第9B圖之IXD-IXD線的剖面圖。 第9 E圖是同個滑動件的左側視圖。 第9 F圖是同個滑動件的右側視圖。 桌10A圖是弟8圖所示的滑動件的立體圖。 第10B圖是從與第i〇A圖相反方向觀看同個滑動件的 立體圖。 第1 0 C圖是表示將同個滑動件翻過來之狀態的立體圖 〇 第10D圖是從與第10C圖相反方向觀看同個滑動件的 K體圖。 第1 1 A圖是擋門的前視圖。 第11B圖是同個擋門的俯視圖。 第11C圖是同個擋門的仰視圖。 第1 1 D圖是同個擋門的側視圖。 【主要元件符號說明】 2 :外殼 3 :基座 3 3 a :第2預壓空間部 3 6 :凸輪銷 3 7 :凸輪銷 -28- 200916866 5 :蓋子 58b :供給孔 5 9b :供給孔 7:滑動件（光纖固定手段） 7 2 a :凸輪孔 72b :凸輪孔 7 3 a :平坦面 8 :擋門（開閉構件） 9 ··擋門（開閉構件） 1 〇 :金屬套筒（套筒） 1 2 :套接管 14 :套殼 1 5 :線圏彈簧（彈性體） 17 :中繼用光纖 18:光纖（一方的光纖） -29Dc is relatively guided. The slider 7 is slidable along the intersecting direction Dc. 〇 When the slider 7 is farthest from the metal sleeve 10, the slider 7 is in a state of floating the susceptor 3. At this time, the insertion of the optical fiber 18 into the second optical fiber receiving groove 33 can be easily performed. The position of the slider 7 at this time is the position at which the optical fiber can be inserted. If the slider 7 is moved toward the metal sleeve 10 from the fiber insertable position, the cam pins 36, 37 are moved relative to each other within the holes 72a, 72b, respectively, and the cam pins 36, 37 are respectively locked. The narrow neck portion of the holes 72a, 72b. At this time, the slider 7 presses the optical fiber 18 to the susceptor 3, and fixes the optical fiber 18 to the susceptor 3. The position of the slider 7 at this time is the fiber fixing position. An optical fiber pressing portion 73 is formed on the lower surface 71b of the cover plate 71. A flat surface 73a and an inclined surface 73b are formed on the side of the base 3 of the optical fiber pressing portion 73. The optical fiber pressing portion 73 is fitted into the central concave portion 30 of the susceptor 3, and the flat surface 730a is in line contact with the covering portion 18b (see Fig. 1) of the optical fiber 18, and presses the optical fiber 18 . The inclined surface 73b is substantially parallel to the intersecting direction Dc (see FIG. 9A). Figure 1 1 A is the front view of the door, the 1 1 B is the top view of the same door, the 1 1 C picture is the bottom view of the same door, the 1 1 D picture is the same door Side view. As shown in Figs. 1 1 A to 1 1 D, the shutter (opening and closing member) 8 is substantially long plate-shaped. Two recesses 81 -17- 200916866 are formed on the upper surface 8a of the shutter 8. Further, engaging pieces 82 and 83 are formed in the longitudinal direction of the shutter 8 respectively. The thickness of the engaging pieces 82, 83 is thinner than the thickness of the portions other than the engaging pieces 82, 83 of the shutter 8. The shutter 8 is detachably received in the receiving groove 56 of the cover 5. The shutter 8 is attached or detached to the receiving groove 56 to open and close the supply opening 5 8 b of the cover 5. Since the shutter (opening and closing member) 9 has the same structure as that of the shutter 8, it is convenient to put the symbols of the respective portions of the opening and closing member 9 in the 11A to 11D drawings, and the description of the shutter 9 is omitted. The upper surface 9a, the recessed portion 91, and the engaging pieces 92, 93 of the shutter 9 correspond to the upper surface 8a of the shutter 8, the recess 81, and the engaging pieces 82, 83, respectively. The shutter 9 is slidably received in the receiving groove 57 of the cover 5. The shutter 9 slides in the housing groove 57 to open and close the hole 5 9 b of the cover 5. In this embodiment, as the material of the shutter 8, an elastically deformable resin is used. Although the material as the shutter 9 is not necessarily an elastically deformable material ', in order to achieve common parts with the shutter 8, the same material as the shutter 8 is used. The mechanical joint 1 is covered with a boot 16 that can be passed through the optical fiber 18. Next, the connection operation of the optical fiber 18 of the optical connector of the embodiment will be described. The optical connectors are assembled in advance before connecting the work. Further, the coating portion 8b at the end portion of the optical fiber 18 is removed, and the fiber center portion 18a is exposed. The operation of assembling the optical connector is roughly divided into two operations. One -18- 200916866 is the operation of assembling the ferrule 12 and the coil spring 15 in the casing 14 and the other operation is to assemble the mechanical joint 1. The following is a detailed description of these operations. For assembling the ferrule 12 and the coil spring 15 in the casing 14, the ferrule body ih of the ferrule 12 is first passed through the hole 142b of the partition wall 142a of the second casing member 142. The chamber 142c is connected to the second chamber 142d. At this time, the flange portion 1 2 2 of the ferrule 1 2 abuts against the partition wall 14 2 a or remains in the first chamber 142c. Next, the coil spring 15 is disposed in the accommodating portion 1 4 1 b of the first casing member 141. In this state, the first casing member 14 4 is inserted into the first chamber 142c of the second casing member 142. As a result, the projection 141f of the first casing member 141 is fitted into the locking hole I42e of the second casing member 142, and the first casing member 141 and the second casing member M2 are joined (see FIG. 3C). . Thereafter, the first and second casing members 141, 142 are inserted into the third casing member 143. As a result, the projection 142f of the second casing member 142 is fitted into the notch 143a of the third casing member 143 (see Fig. 4), and the second casing member 142 is locked to the third casing member 143. As described above, the ferrule 2 assembled to the casing 14 can only move a predetermined distance within the casing 14 along the longitudinal direction of the ferrule body 121. Further, the front end portion of the sleeve body 1 2 1 protrudes from the front end of the casing 14 by the pressing force ' of the coil spring 15. For assembling the mechanical joint 1, the metal sleeve 1 is first accommodated in the sleeve receiving member 31 of the base 3, then the cover 5 is attached to the base 3, and finally the -19-200916866 shutter 9 is housed in the cover 5 for accommodation. Groove 5 7. At this time, the shutter 9 is positioned such that the supply hole 5 9 b of the cover 5 is not blocked by the shutter 9 . For example, i: 'For connecting the optical fiber bundle 8 to the optical connector assembled in advance, it is held in the relay optical fiber 17 of the ferrule 12, and is connected to the core wire of the one end side portion 3b of the mechanical joint 1. The portion 3 2 b is inserted into the first fiber receiving groove 3 2 . Then, the one end side portion 3b of the mechanical joint 1 is inserted into the insertion port 14ld of the one sleeve member 141, and the projection 3e of the one end side portion 3b is fitted to the recessed portion I41h of the insertion opening 141d. The projection 3e engages with the recess 141h. When all of the one end side portion 3b is inserted into the insertion port 1 4 1 d, the end portion of the relay optical fiber 17 reaches the window hole i〇b of the metal sleeve. Further, if the projection 3e is fitted to the recessed portion 14 1h, the one end side portion 3b of the mechanical joint 1 does not easily fall off from the casing 丨4. The length of the relay optical fiber 17 is set so that the position of the end portion of the relay optical fiber 17 inserted into the metal sleeve 1 is located at the center of the window hole 1 0 b of the metal sleeve 1 . Thereafter, a so-called gel-like instant adhesive is injected into the concave portion 58 through the supply hole 58b of the cover 5. At this time, the instantaneous adhesive will slightly overflow from the supply hole 58b. As a momentary adhesive, it is preferred to have a slight flexibility after curing. Next, the engaging piece 82 of the shutter 8 is inserted into the recessed portion 58 of the cover 5 (refer to FIG. 7C and FIG. 1), and a force is applied to the blocking door 8 to substantially deflect the blocking door 8 into a U-shape. In this state, the engaging piece 8 3 of the shutter 8 is inserted into the insertion hole 14 1 g of the first casing member 141, and the force applied to the door -20-200916866 8 is released. As a result, the door 8 is returned to the straight state due to its elastic force, and is accommodated in the receiving groove 56 of the cover 5. Further, the transient adhesive in the recess 58 is pressed by the shutter 8 and flows to surround the metal sleeve! A part of the one end portion of the 流入 flows into the end portion of the core wire receiving hole 10a. As a result, the relay optical fiber 17 is strongly fixed to one end portion of the metal sleeve 1b, and the relay optical fiber 17 is prevented from directly contacting the opening edge of one end portion of the core wire receiving hole 10a. Thereafter, the slider 7 is slid to be separated from the cover 5 in the intersecting direction Dc. As a result, the cam pins 36, 37 of the base 3 are relatively moved within the cam holes 7 2 a, 7 2 b of the slider 7, and are in contact with one end of the cam holes 7 2 a, 7 2 b The position of the slider 7 at which the slider 7 is stopped at this time is at the position where the optical fiber is inserted (the position where the optical fiber 18 is easily inserted into the outer casing 2). At this position, the slider 7 is in a state of floating above the susceptor 3, and the optical fiber 18 is easily inserted into the second fiber accommodating groove 3 3 . Next, the optical fiber 18 is housed in the second optical fiber receiving groove 3 3, and the optical fiber center portion 18a of the optical fiber 18 is inserted into the core receiving hole 10a of the metal sleeve 10 (refer to FIG. 3A). ). Thereafter, a gel-like instantaneous adhesive is injected into the concave portion 59 through the supply hole 5 9b of the cover 5. At this time, the instantaneous adhesive will slightly overflow from the supply hole 59b. Next, the slider 7 is pushed toward the cover 5 along the longitudinal direction L, and as shown in FIGS. 3A and 3B, the slider 7 is moved from the fiber insertion position to the second fiber fixing position (fiber 1 8 is fixed to the position of the outer casing 2 by the slider 7. -21 - 200916866 At this time, the cam pins 36, 37 are relatively guided by the cam holes 72a, 72b, and the slider 7 is moved along the Dc in the intersecting direction. Since the flat surface 73a of the optical fiber pressing portion 73 of the slider 7 comes into contact with the optical fiber 18 during the movement, the slider 7 moves to the optical fiber fixing position while transferring the optical fiber 18 to the relay optical fiber 17. Further, the end portion of the optical fiber center portion 18a of the optical fiber 18 is formed at a portion where the window hole 10b of the metal sleeve 10 is formed, and is overlapped with the end portion of the relay optical fiber 17 to further end the end of the relay optical fiber 17 The portion moves toward the one end side portion 3b. As a result, the relay fiber bundle 7 is deflected in the second preload space 32a, and the fiber center portion 18a of the fiber 18 is deflected in the second preload space 33a due to the restoring force. Further, since the end portion of the relay optical fiber 17 and the end portion of the optical fiber center portion 18 a of the optical fiber 18 are overlapped at the portion of the window hole 1 〇b in which the metal sleeve 1 形成 is formed, there is a relay Air or the like between the end of the optical fiber 17 and the end of the optical fiber central portion 18a is discharged from the aperture 1b. Further, the end portion of the relay optical fiber 17 and the end portion of the optical fiber center portion 18 a after the relay optical fiber 17 and the end portion of the optical fiber center portion 18a overlap each other are moved toward the one end side portion 3 b , leaving the window hole 10b of the metal sleeve 10. Therefore, the external light entering the metal sleeve 10 through the window 10b cannot enter the end portion of the relay optical fiber 17 and the end portion of the optical fiber center portion 18a. When the slider 7 is moved from the fiber insertion position to the fiber fixing position, the slider 7 is brought into contact with the shutter 9, and the shutter 9 is moved toward the sleeve pressing portion 53 of the cover 5. At this time, while the supply port 5 9b of the cover 5 is closed by the shutter 9, the engaging piece 93 of the shutter 9 is relatively inserted into the engaging recess 71g of the slider -22-200916866. Further, since the engaging piece 92 of the shutter 9 is submerged under the engaging piece 53b of the cover 5, the shutter 9 is locked by the cover 5 and the slider 7. When the supply hole 59b of the cover 5 is closed by the shutter 9, the instantaneous adhesive in the recess 59 is pressed by the shutter 9, and flows to surround the other end of the metal sleeve 1 ,, and a part thereof flows into the heart. The end of the wire receiving hole 1 〇a. Thereby, the fiber center portion 18 8 of the optical fiber 18 is firmly fixed to the other end of the metal sleeve 10, and the fiber center portion 18 8 is directly prevented from directly contacting the other end of the core receiving hole 10a. The opening edge of the part. Further, before the adhesive is injected into the recesses 5 8 and 59, the adhesive fiber 17 and the optical fiber 18 are pressed beforehand, so that the end portion of the relay fiber 17 and the fiber center portion 1 8 a The ends are strongly lapped, followed by a metal sleeve 10. If the adhesive of the recesses 5 8 and 59 is hardened, the connection of the relay optical fiber 17 to the optical fiber 18 is completed. According to the optical connector of this embodiment, the following effects are obtained. As described above, when the slider 7 is movably disposed at the other end portion of the outer casing 2 between the optical fiber insertable position and the optical fiber fixed position, and the slider 7 is moved from the optical fiber insertable position to the optical fiber fixed position, one side The distal end portion of the optical fiber 18 is transferred to the other end portion of the relay optical fiber 17, and one optical fiber 18 is fixed to the outer casing 2. Conversely, when the slider 7 is moved from the fiber fixing position to the fiber insertable position, the fixed state of the optical fiber 18 to one side of the casing 2 is released. Therefore, the connection work between the relay optical fiber 17 and one of the optical fibers 18 can be easily performed. -23- 200916866 In the conventional optical connector, when the wedge inserted between the base portion and the pressing portion is unplugged, the end face of the short fiber and the optical fiber is picked up from the fiber groove. The guide slots are staggered and the short fibers and fibers cannot be properly connected. On the other hand, in this embodiment, the operation of pulling out the wedge is not performed, and when the slider 7 is moved from the optical fiber insertable position to the optical fiber fixing position, since the slider 7 is configured to relay the front end portion of the optical fiber 18 Since the other end portion of the optical fiber 17 is transferred, the relay optical fiber 17 and the optical fiber 18 can be connected correctly. Since the optical fiber pressing portion 7 of the slider 7 has the flat surface 733a, the optical fiber 18 can be strongly pressed by the flat surface 73a, and the optical fiber 18 is hard to be detached. Since the relay optical fiber 17 is held in the ferrule 12, if the length of the relay optical fiber 17 is correctly adjusted, although the transfer accuracy of the optical fiber 18 by the slider 7 is improved, it is possible to form a metal. A portion of the aperture 1 〇b of the sleeve 10 overlaps the end of the relay optical fiber 17 and the end of the optical fiber central portion 18 a. Therefore, since the dimensional accuracy of the slider 7 can be made lower than that of the conventional mechanical joint lever, the cost can be reduced. Since the adhesive is supplied to both end portions of the metal sleeve 1〇 by the supply holes 58b and 59b of the cover 5, it is possible to prevent the relay optical fiber bundle 7 and the optical fiber center portion 18a from directly contacting the metal sleeve 1 by the adhesive. The opening edge of the 心's heart line receiving hole 1 〇a. As a result, even if the mechanical joint 1' is placed in a place where there is a lot of vibration, the relay fiber can be remarkably reduced! 7 and the possibility of damage to the center of the fiber 1 8 a due to the metal sleeve 1 〇. -24- 200916866 When the supply holes 58b, 59b of the cover 5 are closed by the shutters 8, 9, since the adhesive is pressed into the outer casing 2, the relay optical fiber 17 and the optical fiber 18 can be surely attached to the metal sleeve. Cartridge 10. Before the curing agent is applied, the relay optical fiber 17 and the optical fiber 18 are pressed in advance by the slider 7, so that the relay optical fiber 17 and the optical fiber 18 are strongly overlapped, and the relay optical fiber 17 is The fiber 18 is followed by a metal sleeve 1 〇. As a result, it is possible to prevent the light transmission efficiency from deteriorating. Further, since the optical fiber pressing portion 73 is formed on the slider 7, the flat surface 73a of the optical fiber pressing portion 73 is in linear contact with the optical fiber 18, so that the slider 7 can strongly hold the optical fiber 18. Further, since the relay optical fiber 17 and the optical fiber 18 are attached to the metal sleeve 1', even if the optical fiber 18 is elongated, it is not easily detached from the outer casing 2. Further, if the slider 7 is moved from the optical fiber insertion position to the optical fiber fixing position, the shutter 9 can be automatically closed by the shutter 9 to automatically close the supply opening 5 9b ' of the cover 5 and the door 9 can be automatically locked. Since a plurality of recesses 3f are provided on the lower surface of the susceptor 3, deformation of the susceptor 3 during molding can be prevented, and electric energy and materials used for molding can be reduced. Further, the shutters 8 and 9 can also be rotatably coupled to the base 3 or the cover 5. Further, in the above embodiment, the optical connector in which the optical fibers for the single core are connected to each other has been described, but the present invention can also be applied to the optical connector for a multi-core. In the above embodiment, the flat surface 73b is formed on the optical fiber of the slider 7 in the pressing portion 73 of the -25-200916866. However, the surface of the optical fiber pressing portion 73 that presses the optical fiber 18 is not limited to the flat surface 73b. Increasing the holding force may also be a waveform that undulates toward the length of the optical fiber 18. Further, in the above-described embodiment, the relay optical fiber 17 and the optical fiber 18 are attached to the metal sleeve 10', but the situation in which the relay optical fiber 17 and the optical fiber 18 are forcibly pulled up is reduced, or In the case where the optical connector is less vibrated, the relay optical fiber 17 and the optical fiber 18 may not be attached to the metal sleeve 10. Further, although the first pre-compression space portion 32a is formed in the susceptor 3, the first pre-compression space portion 32a may be omitted. Further, in the above embodiment, the opening and closing members use the two shutters 8 and 9, but the opening and closing members may be provided. Further, in the above embodiment, the metal sleeve 1 is used, but the material of the sleeve is not limited to metal. Further, in the above-described embodiment, the insertion port i4ld for fixing the one end side portion 3b of the outer casing 2 to the casing 14 by the projection 3e is formed, but the female thread may be formed at the one end side portion 3b at the insertion port 1 4丨d forms a male thread 'fixed by the screwing of the female thread and the male thread, or the one end side portion 3b is fixed to the insertion port 141d using a pin or the like. The above is a description of the preferred embodiments of the invention, and it is apparent that various modifications may be made without departing from the spirit and scope of the invention.
