Description

【0001】
【発明の属する技術分野】
本発明は、部品着脱自在に接続するため光コネクタハウジングを備えて、主に光通信に用いられる光コネクタおよびその光コネクタと光部品との接続構造に関するものである。
【0002】
【従来の技術】
近年、光ファイバを用いた光通信が盛んに行われており、光ファイバの高密度実装のため、光ファイバを接続するために用いられる光コネクタの小型化や、光モジュールの高密度実装化などが検討されている。
【0003】
この種のタイプの光コネクタ11を図5に示す。12lは光コネクタハウジング部で、該光コネクタハウジング部12lの基端側の面12dより伸長された2本のアーム部12aを有し、該アーム部12aは先端部に係合部12bが形成され内壁には開角駆動カム12cが設けられている。この開角駆動カム部12cは、テ−パ面12eと後端面12fとによりなる突起部12iにより形成されている。13はスライダで被開角駆動カム部13aと当接部13bと把持部13eとが設けられている。光コネクタハウジング12は、前記光コネクタハウジング部12lと前記スライダ13とによりなり、スライダ13は移動可能に設けられている。4はフェルールで、光ファイバが取り付けられている。5はバネで、フェルール4を接続相手側へ付勢するために設けられる。11は光コネクタで、前記光コネクタハウジング12の光コネクタハウジング部12lの2本のアーム部12a間のスライダ13の被開角駆動カム部13aより先端側にフェルール4を収容し、該フェルール4の後端面から前記基端側の面12dにかけてバネ5を設けて形成されている。6は光部品で、被係合部6aを有する。
【0004】
図5(a)は、前記係合部12bとの前記被係合部6aとを係合して、光コネクタ11と光部品6との接続を示したものである。この接続を解除するには把持部13eを把持して、図5(b)に示すように、図5(a)の状態からスライダ13を接続相手側とは反対側へ移動し、被開角駆動カム部13aをテ−パ面12eに当接させ、さらに移動することにより2つのアーム部12aを開角駆動し、これらのアーム部12aの開角の保持は、被開角駆動カム部13aがテ−パ面12eに沿って接続相手側へ移動しないように把持部13eを把持して行われる。
【0005】
【発明が解決しようとする課題】
しかしながら、図6に示すように、接続の解除を行うとき一方のアーム部12aの係合しか外れないことがある。これは、被開角駆動カム部13aをテ−パ面12eに当接させて2つのアーム部12aの開角の保持が行われるので不安定であり、前記係合部12bと被係合部6aとの係合のバランスや摩擦力等により、係合力の弱い方のアーム部12aしか係合が外れないためである。
【0006】
このとき、バネ5はフェルール4を接続相手の光部品6側へ付勢しており、これに伴い他方のアーム部12aの係合部12bは、被係合部6aに係合したまま接続相手側とは反対の方向に付勢されるので、係合部12bと被係合部6aとの係合は強固となる。よって、アーム部12aを開角駆動させようとして把持部13eを接続相手側とは反対方向へ引っ張ってもスライダ13を移動させることは非常に困難であり、その解除は特別な治具を用いる等しないと難しいという問題があった。
【0007】
また、図7に示すように、スライダ13を接続相手の光部品6とは反対方向へ移動させたとき、被開角駆動カム部13aが、開角駆動カム部12cを乗り越えて開角駆動カム部12cと基端側の面12dとの間に入り込んでしまうことがある。この状態になると特別の治具を用いる等してアーム部12aを開角駆動しなければ解除できず、着脱作業が困難となることがあるという問題があった。
【0008】
本発明は、上記従来の課題を解決するためになされたものであり、専用の着脱治具等を用いずに、光コネクタの着脱を容易に、かつ正確に行うことを可能とする光コネクタハウジングを備えた光コネクタおよびその光コネクタと光部品との接続構造を提供することを目的とする。
【0009】
【課題を解決するための手段】
上記目的を達成するために、本発明は次のような構成をもって課題を解決するための手段としている。すなわち、第1の発明の光コネクタは、基端側の面の両端側からそれぞれアーム部を伸長し、該アーム部の先端部には接続相手に係合する係合部が設けられ、かつ、該アーム部の内壁には先端側からテ−パ状に立ち上がる立ち上がり面を備えた突起部が形成された光コネクタハウジング部と、先端部に前記立ち上がり面に当接して前記アーム部を開角駆動する当接部を備えたスライダとからなり、該スライダは当接部をアーム部間に配置して前記光コネクタハウジング部に移動可能に設けられ、該スライダを移動させてこのスライダの当接部と立ち上がり面とを当接させてアーム部を開角駆動する光コネクタハウジングを備え、前記アーム部の突起部には前記立ち上がり面の立ち上がり先端側に隣接した当接面を設け、該当接面に前記スライダの当接部を当接させてアーム部の開角を保持するとともに、前記アーム部間に、接続端面と後端面とを有するフェルールを収容し、該フェルールの後端面から前記光コネクタハウジング部の基端側の面にかけて前記フェルールを接続相手側に付勢する付勢部材を設け、前記スライダをフェルールの後端面と光コネクタハウジング部の基端側の面との間に移動可能に設け、前記スライダを移動させて該スライダの先端部を光コネクタハウジング部の基端側の面に当接させたとき、前記スライダの当接部と前記アームの突起部の当接面は互いに当接してアーム部の開角を保持している構成をもって課題を解決する手段としている。
【0010】
また、第2の発明の光コネクタは、上記第1の発明の光コネクタのスライダの当接部に当接面を設け、このスライダの当接面と前記アーム部の突起部の当接面とを当接させてアーム部の開角を保持する構成をもって課題を解決する手段としている。
【0013】
さらに、第の発明の光コネクタと光部品の接続構造は、上記第1または第2の発明の光コネクタの接続相手側光部品には前記光コネクタハウジング部のアーム部に設けられた係合部と係合する被係合部が設けられ、前記光コネクタの係合部が前記接続相手側光部品の被係合部に係合することにより前記光コネクタと接続相手側光部品とが接続されている構成をもって課題を解決する手段としている。
【0014】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。なお、本実施形態例の説明において、従来例と同一名称部分には同一符号を付す。図1は、本発明に係る光コネクタハウジングを備えた光コネクタの一実施形態例を示す斜視図である。
【0015】
図1に示すように、光コネクタハウジング部2lは、基端部2kの基端側の面2dの両端側からそれぞれアーム部2aを伸長して略コの字状に形成され、このアーム部2aの先端部には、接続相手の光部品6の被係合部と係合する係合部としての爪部2hが設けられている。また、該アーム部2aの内壁には突起部2iを内側に突き出して開角駆動カム部2cが設けられている。この突起部2iは、アーム部2aの内壁のアーム部2aの先端側より立ち上がるテ−パ面2eと、当接面2gと、アーム部2aの内壁からほぼ垂直に立ち上がる後端面2fにより形成されている。両アーム部2a、2aのそれぞれの当接面2g、2gは互いに対向してほぼ平行に設けられている。また、基端部2kには、基端側の面2dから後端面2jにかけてスライダ3を挿通する挿通孔が設けられ、基端側の面2dにはバネ5の端部を収容する収容部2mが形成されている。
【0016】
3はスライダで、長手方向にブーツ8が挿通される挿通孔が形成されている。その先端部には被開角駆動カム部3aが設けられ、該被開角駆動カム部3aの先端側の両側面には当接部3bが外側に突き出されて設けられている。また、駆動カム部3aにはバネ5が挿通される挿通孔が形成されている。3dは被開角駆動カム部3aの後端面である。3eはスライダ3を移動させる際に把持して操作する把持部で、3fは把持部3eの後端面側を片持ち梁状に支持して設けられた突起である。
【0017】
4はMTフェルール等のフェルールで、後端面4bから複数の光ファイバが並設された光ファイバテープ心線7を挿入して取り付けられている。このフェルール4の先端側には図示しない光ファイバ挿通孔が形成されている。この光ファイバ挿通孔に、前記光ファイバテープ心線7の光ファイバを、先端部の被覆を除去して露出して挿通し、接続端面4aが形成されている。また、この接続端面4aには図示しないガイドピン挿入穴が形成されている。図中、8はブーツで前記光ファイバテープ心線7を保護するために設けられている。5はバネで、フェルール4を接続相手側に付勢するために設けられる。
【0018】
6はMTフェルール型のパッケージを備えたMTインタ−フェイス等の光部品で、例えば基板側光モジュール等が接続されている。この光部品6には前記光コネクタハウジング2の係合部としての爪部2hに係合する被係合部としての嵌合凹部6bが設けられている。6cは接続端面で、この接続端面6cに、前記フェルール4の光ファイバと接続される図示しない光ファイバが配置されている。6dはガイドピンで、前記フェルール4に形成されたガイドピン挿入穴に挿入される。
【0019】
本実施形態例の光コネクタに設けられている光コネクタハウジング2は、図1に示されるように前記光コネクタハウジング部2lと前記スライダ3とからなる。スライダ3は、前記光コネクタハウジング部2lの基端部2kに形成された挿通孔に前記基端側の面2d側から把持部3e側を挿通して、被開角駆動カム部3aの当接部3bを前記アーム部2a間に配置して、前記光コネクタハウジング部に長手方向に移動可能に設けられている。
【0020】
この光コネクタハウジング2は、スライダ3を前記基端側の面2d側へ移動させると、このスライダ3の被開角駆動カム部3aに設けられた当接部3bは前記アーム部2aの突起部2iのテ−パ面2eに当接してアーム部2aは開角駆動され、さらにスライダ3を移動させると前記当接部3bと前記当接面2gとが当接してアーム部2aの開角を保持する構成となっている。
【0021】
よって、アーム部2aの開角の保持は、当接部3bを、テ−パ面2eではなく当接面2gに当接させることにより確実に行われるので、容易に解除することができる。
【0022】
そして、前記被開角駆動カム部3aの横断面は基端部2kの挿通孔よりも大きく形成されているため、スライダ3を後方に移動させたとき、後端面3dは光コネクタハウジング部2lの基端側の面2dに当接するので、光コネクタハウジング部2lよりはずれることはない。また、スライダ3を前方に移動させると、突起3fは光コネクタハウジング2の後端面2jに当接するので、スライダ3は光コネクタハウジング部2lよりはずれることはない。
【0023】
さらに、スライダ3を移動して被開角駆動カム部3aの後端面3dを光コネクタハウジング2の基端側の面2dに当接させたとき、被開角駆動カム部3aに設けられた当接部3bは、光コネクタハウジング部2lの突起部2iに形成された当接面2gに確実に当接するように設けられている。よって、スライダ3の当接部3bは、光コネクタハウジング部2lの突起部2iを乗り越えて該突起部2iと基端部2kとの間に入り込むことはない。
【0024】
コネクタハウジング2は以上のように構成されており、次に、本実施形態例の光コネクタ1について図1に基づいて説明する。光コネクタ1は、前記光コネクタハウジング2と前記フェルール4とバネ5とからなる。ブーツ8の外側にバネ5を設け、このブーツ8をスライダ3に形成された挿通孔にアーム部2aの先端側から挿通して、前記アーム部2a間にフェルール4を配置して収容して光コネクタ1が設けられる。このときスライダ3の被開角駆動カム部3aはフェルール4と光コネクタハウジング部2lの基端部2kとの間に配置されて移動可能に設けられ、バネ5はフェルール4の後端面4bから基端側の面2dにかけて配置して設けられる。
【0025】
本実施形態例の光コネクタ1は以上のように構成されており、次に、本実施形態例の光コネクタと光部品との接続構造について図2に基づいて説明する。
1は光コネクタで、6は光部品である。5はバネで、簡略化して図示している。
【0026】
本実施形態例の光コネクタ1を光部品6と接続とその解除は、光コネクタ1に設けられたスライダ3の把持部3eを把持して行われる。尚、光部品6において一部断面図で示されているが、それは被係合部の嵌合凹部6bを表示するためである。まず、図2(a)に示されるように、光コネクタ1の光コネクタハウジング2のアーム部2aの爪部2hを光部品6の嵌合凹部6bに対向させる。そして、光コネクタ1を光部品6側へ移動して、同図の(b)に示すように、フェルール4のガイドピン挿入穴に光部品6のガイドピン6dを挿入してそれぞれの接続端面4aと接続端面6cを当接させてフェルール4と光部品6を接続する。それから同図の(c)に示すように、嵌合凹部6bと爪部2hとを係合して光部品6と光コネクタ1との接続が完了する。
【0027】
このとき、バネ5は、爪部2hと嵌合凹部6bとが係合したまま爪部2hを接続相手の光部品6とは反対方向へ付勢するので、その係合は強固に行われる。また、バネ5は、接続相手側へフェルール4を付勢するので、光コネクタ1と光部品6との光ファイバの接続は確実に行われる。
【0028】
次に、光コネクタ1を光部品6から外すときには、把持部3eを把持して引っ張りスライダ3を後方側に移動して、図3(a)に示すように、被開角駆動カム部3aに設けられた当接部3bを光コネクタハウジング2のアーム部2aに設けられた突起部2iのテ−パ面2eに当接させ、さらにスライダ3を後方に移動してアーム部2aを開角駆動して、図3(b)に示すように前記当接部3bと突起部2iの当接面2gとを当接させてアーム部2aの開角を保持する。
【0029】
このとき、当接部3bは、アーム部2aを開角駆動するテ−パ面2eではなく当接面2gに当接してその開角を保持するためアーム部2aの開角の保持は安定し、図3(c)に示すように、その接続を簡単に解除することができる。
【0030】
また、図4に示すように、一方のアーム部2aの係合が解除されないことがあったとしても、前記当接部3bと前記当接面2gとは当接してアーム部2aの開角は確実に保持されているので、把持部3eを把持しての光コネクタ1の配置の修正は容易であり、その解除は簡単に行うことができる。
【0031】
以上説明したように、本実施形態例によれば、スライダ3を後方側に移動して、被開角駆動カム部3aに設けられた当接部3bと光コネクタハウジング2のアーム部2aに設けられた突起部2iのテ−パ面2eとを当接させてアーム部2aを開角駆動し、さらに、当接部3bと突起部2iの当接面2gとを当接させてアーム部2aの開角を保持するので、アーム部2aの開角の保持は安定し、光コネクタ1と光部品6との接続を容易に解除することができる。
【0032】
したがって、本実施形態例の光コネクタ1は、特別な治具を用いることなく光部品6と着脱自在に接続できるので、それにより、光コネクタ1が有する光ファイバの高密度化を図ることができるため、小型化することができる。
【0033】
さらに、本実施形態例では、光コネクタハウジング2および光コネクタ1の構成は、上記のごとく非常に簡単であるために、光コネクタ1と光部品6との接続を非常に高密度に配設できる。
【0034】
尚、上記実施形態例においては、スライダ3の被開角駆動カム部3aに設けられた当接部3bと、光コネクタハウジング2のアーム部2aに設けられた開角駆動カム部2cとして形成された突起部2iに設けられた当接面2gとを当接させ、アーム部2aの開角を保持したが、図1に示すように当接部3bに当接面3cを形成して、この当接面3cと前記当接面2gとを面で接触するように当接すれば、アーム部2aの開角の保持はより確実に行うことができ好ましい。
【0035】
また、本発明に適用されるフェルールは、MTフェルール等に限らず、円筒型のフェルールを用いてもよい。
【0036】
さらに、本発明の光コネクタ1に接続される接続相手側の光部品は、その仕様等、適宜設定されるものである。
【0037】
また、爪部2hと嵌合凹部6bとを係合して光コネクタ1と光部品6とを接続してから、光コネクタ1にカバー(図示せず)を設けてもよい。例えば光部品6側にネジ止めする等すれば、カバーを簡単に光コネクタ1に設けることができる。両者の接続を解除するときにはこのカバーを取り外して行われる。
【0038】
【発明の効果】
本発明によれば、光コネクタハウジングのアーム部の内壁に形成された突起部に当接面を設け、この当接面と、スライダに設けられた当接部とを当接してアーム部の開角を保持するので、光コネクタと接続相手側の接続の解除を容易に行うことができる。
【0039】
また、本発明によれば、光コネクタハウジング部に設けられたスライダを移動させて光コネクタハウジング部の基端側の面に当接させたとき、前記スライダの当接部と前記アームの突起部の当接面は互いに当接してアーム部の開角を保持するので、当接部が突起部を乗り越えてこの突起部と基端側の面との間に入り込んでしまうことはなく、光コネクタと接続相手側と接続相手側の接続の解除を確実に行うことができる。

BACKGROUND OF THE INVENTION
The present invention includes an optical connector housing for detachably connected to the optical component, to a connection structure between main optical connector and an optical connector and the optical components used in optical communication.
[0002]
[Prior art]
In recent years, optical communication using optical fibers has been actively carried out. For optical fiber high-density mounting, miniaturization of optical connectors used to connect optical fibers, high-density mounting of optical modules, etc. Is being considered.
[0003]
An optical connector 11 of this type is shown in FIG. Reference numeral 12l denotes an optical connector housing portion having two arm portions 12a extending from the proximal end surface 12d of the optical connector housing portion 121, and the arm portion 12a has an engaging portion 12b formed at the distal end portion. An open angle drive cam 12c is provided on the inner wall. The opening angle drive cam portion 12c is formed by a protrusion 12i composed of a taper surface 12e and a rear end surface 12f. Reference numeral 13 denotes a slider provided with an opening angle drive cam portion 13a, an abutting portion 13b, and a gripping portion 13e. The optical connector housing 12 is composed of the optical connector housing portion 121 and the slider 13, and the slider 13 is movably provided. 4 is a ferrule to which an optical fiber is attached. A spring 5 is provided to bias the ferrule 4 toward the connection partner. Reference numeral 11 denotes an optical connector. The ferrule 4 is accommodated on the distal end side of the open angle drive cam portion 13a of the slider 13 between the two arm portions 12a of the optical connector housing portion 12l of the optical connector housing 12, and the ferrule 4 It is formed by providing a spring 5 toward the rear end face or we face 12d of the base end side. An optical component 6 has an engaged portion 6a.
[0004]
5A shows the connection between the optical connector 11 and the optical component 6 by engaging the engaged portion 6a with the engaged portion 12b. To release this connection, the gripping portion 13e is gripped, and as shown in FIG. 5B, the slider 13 is moved from the state of FIG. The drive cam portion 13a is brought into contact with the taper surface 12e, and further moved to drive the two arm portions 12a at an open angle. The opening angle of these arm portions 12a is maintained by the driven angle drive cam portion 13a. Is performed by gripping the grip portion 13e so as not to move toward the connection partner side along the taper surface 12e.
[0005]
[Problems to be solved by the invention]
However, as shown in FIG. 6, only one arm portion 12 a may be disengaged when the connection is released. This is unstable because the opening angle drive cam portion 13a is brought into contact with the taper surface 12e and the opening angle of the two arm portions 12a is maintained, and the engagement portion 12b and the engagement portion are not stable. This is because only the arm portion 12a having the weaker engaging force can be disengaged due to the balance of engagement with the friction member 6a, the frictional force, and the like.
[0006]
At this time, the spring 5 urges the ferrule 4 toward the optical component 6 that is the connection partner, and accordingly, the engagement portion 12b of the other arm portion 12a remains engaged with the engaged portion 6a. Since it is urged | biased in the direction opposite to the side, engagement with the engaging part 12b and the to-be-engaged part 6a becomes firm. Therefore, it is very difficult to move the slider 13 even if the gripping part 13e is pulled in the direction opposite to the connection partner side in order to drive the arm part 12a to open the angle, and a special jig is used for the release. There was a problem that otherwise it was difficult.
[0007]
Further, as shown in FIG. 7, when the slider 13 is moved in the direction opposite to the optical component 6 to be connected, the opening angle driving cam portion 13a gets over the opening angle driving cam portion 12c and the opening angle driving cam. It may enter between the portion 12c and the proximal surface 12d. In this state, there is a problem that the arm portion 12a cannot be released unless the angle is driven by using a special jig or the like, and the attaching / detaching work may be difficult.
[0008]
The present invention has been made to solve the above-described conventional problems, and an optical connector housing capable of easily and accurately attaching / detaching an optical connector without using a dedicated attaching / detaching jig or the like. and to provide a connection structure between the optical connector and an optical connector and an optical component with a grayed.

An opening angle drive cam portion 3a is provided at the tip portion, and contact portions 3b are provided on both side surfaces of the tip angle side of the opening angle drive cam portion 3a so as to protrude outward. The drive cam portion 3a is formed with an insertion hole through which the spring 5 is inserted. 3d is a rear end surface of the opening angle drive cam portion 3a. Reference numeral 3e denotes a gripping part that is gripped and operated when the slider 3 is moved. Reference numeral 3f denotes a protrusion provided by supporting the rear end surface of the gripping part 3e in a cantilever shape.
[0017]
Reference numeral 4 denotes a ferrule such as an MT ferrule, which is attached by inserting an optical fiber ribbon 7 in which a plurality of optical fibers are arranged in parallel from the rear end face 4b. An optical fiber insertion hole (not shown) is formed on the tip side of the ferrule 4. The optical fiber of the optical fiber ribbon 7 is inserted through the optical fiber insertion hole with the coating of the tip portion removed, and a connection end face 4a is formed. Further, a guide pin insertion hole (not shown) is formed in the connection end surface 4a. In the figure, 8 is a boot provided to protect the optical fiber ribbon 7.

[0019]
As shown in FIG. 1, the optical connector housing 2 provided in the optical connector of the present embodiment example includes the optical connector housing portion 21 and the slider 3. The slider 3 is inserted into the insertion hole formed in the base end portion 2k of the optical connector housing portion 2l from the base end side surface 2d side to the gripping portion 3e side, so that the contact portion of the open angle drive cam portion 3a is brought into contact. A portion 3b is disposed between the arm portions 2a, and is provided in the optical connector housing portion so as to be movable in the longitudinal direction.
[0020]
In the optical connector housing 2, when the slider 3 is moved toward the base end surface 2d, the contact portion 3b provided on the open angle drive cam portion 3a of the slider 3 is a projection of the arm portion 2a. 2a is contacted with the taper surface 2e, and the arm portion 2a is driven to open, and when the slider 3 is further moved, the contact portion 3b and the contact surface 2g come into contact with each other to increase the opening angle of the arm portion 2a. It is the structure to hold.
[0021]
Therefore, the holding of the opening angle of the arm portion 2a is reliably performed by bringing the contact portion 3b into contact with the contact surface 2g instead of the taper surface 2e, and can be easily released.
[0022]
Since the cross section of the opening angle drive cam portion 3a is formed larger than the insertion hole of the base end portion 2k, when the slider 3 is moved rearward, the rear end surface 3d is formed on the optical connector housing portion 2l. Since it comes into contact with the base end surface 2d, it is not displaced from the optical connector housing portion 21. When the slider 3 is moved forward, the protrusion 3f contacts the rear end surface 2j of the optical connector housing 2, so that the slider 3 is not displaced from the optical connector housing portion 21.
[0023]
Further, when the slider 3 is moved so that the rear end surface 3d of the angled drive cam portion 3a contacts the surface 2d on the proximal end side of the optical connector housing 2, the contact angle provided on the angled drive cam portion 3a is set. The contact portion 3b is provided so as to surely contact the contact surface 2g formed on the projection 2i of the optical connector housing portion 21. Therefore, the contact portion 3b of the slider 3 does not get over the projection 2i of the optical connector housing portion 21 and enter between the projection 2i and the base end 2k.
[0024]
The optical connector housing 2 is configured as described above. Next, the optical connector 1 of this embodiment will be described with reference to FIG. The optical connector 1 includes the optical connector housing 2, the ferrule 4 and a spring 5. A spring 5 is provided outside the boot 8, and the boot 8 is inserted into an insertion hole formed in the slider 3 from the distal end side of the arm portion 2a, and a ferrule 4 is disposed and accommodated between the arm portions 2a. A connector 1 is provided. At this time, the opening angle drive cam portion 3 a of the slider 3 is disposed between the ferrule 4 and the base end portion 2 k of the optical connector housing portion 2 l so as to be movable, and the spring 5 is provided from the rear end face 4 b of the ferrule 4. It is arranged and provided over the end surface 2d.
[0025]
The optical connector 1 of the present embodiment is configured as described above. Next, a connection structure between the optical connector and the optical component of the present embodiment will be described with reference to FIG.
1 is an optical connector, and 6 is an optical component. Reference numeral 5 denotes a spring, which is illustrated in a simplified manner.
[0026]
The optical connector 1 according to this embodiment is connected to the optical component 6 and released from the optical connector 1 by gripping the grip portion 3e of the slider 3 provided on the optical connector 1. Note that the optical component 6 is partially shown in a cross-sectional view for displaying the fitting recess 6b of the engaged portion. First, as shown in FIG. 2A, the claw portion 2 h of the arm portion 2 a of the optical connector housing 2 of the optical connector 1 is opposed to the fitting recess 6 b of the optical component 6. Then, the optical connector 1 is moved to the optical component 6 side, and the guide pin 6d of the optical component 6 is inserted into the guide pin insertion hole of the ferrule 4 as shown in FIG. The ferrule 4 and the optical component 6 are connected by bringing the connection end face 6c into contact with each other. Then, as shown in FIG. 5C, the fitting recess 6b and the claw portion 2h are engaged to complete the connection between the optical component 6 and the optical connector 1.
[0027]
At this time, the spring 5 urges the claw 2h in the direction opposite to the optical component 6 to be connected while the claw 2h and the fitting recess 6b are engaged, so that the engagement is firmly performed. Further, since the spring 5 biases the ferrule 4 toward the connection counterpart, the optical fiber connection between the optical connector 1 and the optical component 6 is reliably performed.
[0028]
Next, when the optical connector 1 is removed from the optical component 6, the gripping portion 3e is gripped and the pulling slider 3 is moved to the rear side, as shown in FIG. The provided abutting portion 3b is brought into contact with the taper surface 2e of the protruding portion 2i provided on the arm portion 2a of the optical connector housing 2, and the slider 3 is further moved backward to drive the arm portion 2a to open the angle. Then, as shown in FIG. 3B, the abutment portion 3b and the abutment surface 2g of the projection 2i are brought into contact with each other to hold the open angle of the arm portion 2a.
[0029]
At this time, since the abutting portion 3b abuts against the abutting surface 2g instead of the taper surface 2e for driving the arm portion 2a to open the angle, the opening angle of the arm portion 2a is stably maintained. As shown in FIG. 3C, the connection can be easily released.
[0030]
Further, as shown in FIG. 4, even if the engagement of one arm portion 2a is not released, the contact portion 3b and the contact surface 2g contact each other, and the opening angle of the arm portion 2a is Since it is securely held, it is easy to correct the arrangement of the optical connector 1 by gripping the grip portion 3e, and the release can be easily performed.
[0031]
As described above, according to the present embodiment, the slider 3 is moved rearward and provided on the contact portion 3b provided on the opening angle drive cam portion 3a and the arm portion 2a of the optical connector housing 2. The arm portion 2a is driven to open the angle by contacting the taper surface 2e of the protruding portion 2i, and the arm portion 2a is further contacted by the contact portion 3b and the contact surface 2g of the protruding portion 2i. Therefore, the holding of the opening angle of the arm portion 2a is stable, and the connection between the optical connector 1 and the optical component 6 can be easily released.
[0032]
Therefore, since the optical connector 1 of the present embodiment can be detachably connected to the optical component 6 without using a special jig, it is possible to increase the density of the optical fiber of the optical connector 1. Therefore, the size can be reduced.
[0033]
Furthermore, in the present embodiment, since the configurations of the optical connector housing 2 and the optical connector 1 are very simple as described above, the connection between the optical connector 1 and the optical component 6 can be arranged at a very high density. .
[0034]
In the above embodiment, the contact portion 3b provided on the opening angle drive cam portion 3a of the slider 3 and the opening angle drive cam portion 2c provided on the arm portion 2a of the optical connector housing 2 are formed. The abutment surface 2g provided on the protruding portion 2i is abutted to maintain the opening angle of the arm portion 2a. However, as shown in FIG. 1, the abutment surface 3c is formed on the abutment portion 3b. If the contact surface 3c and the contact surface 2g are in contact with each other so as to contact each other, the opening angle of the arm portion 2a can be more reliably maintained.
[0035]
The ferrule applied to the present invention is not limited to the MT ferrule or the like, and a cylindrical ferrule may be used.
[0036]
Furthermore, the optical component on the connection partner side connected to the optical connector 1 of the present invention is appropriately set such as its specifications.
[0037]
Alternatively, the optical connector 1 may be provided with a cover (not shown) after the claw portion 2h and the fitting recess 6b are engaged to connect the optical connector 1 and the optical component 6. For example, the cover can be easily provided on the optical connector 1 by screwing it to the optical component 6 side. When releasing the connection between the two, this cover is removed.
[0038]
【The invention's effect】
