Description

【０００１】
【発明の属する技術分野】
本発明は、光コネクタをアダプタに着脱するためのコネクタ着脱工具に関する。
【０００２】
【従来の技術】
従来のコネクタ着脱工具は、グリップの先端に１対の挟持片が枢軸を支点に回転可能に設けられ、挟持片と一体に形成されたレバー部を握ることによって挟持片の先端が開放し、緩めるとバネの力によって挟持片の先端が閉塞するようになっている。そこで、レバー部を握って挟持片の先端を開放した状態で光コネクタに差し込み、レバー部から手を放して挟持片によって光コネクタを挟持させ、コネクタ着脱工具を引き抜くことによりアダプタから光コネクタを取り外すようになっていた（例えば、特許文献１参照。）。

特開２００２−２３０１２号公報（第３−４頁、第１図）
【０００４】
【発明が解決しようとする課題】
従来のコネクタ着脱工具は複数のアダプタが高密度に設けられている場合、誤って目的と違う光コネクタを引き抜いてしまったり、光コードが邪魔になって光コネクタの位置が見づらいために光コネクタ手前のコード部分を挟持して引き抜いて損傷させたり、工具が他の光コネクタや光コードに当たって損傷させる虞があった。
【０００５】
そこで上記問題点に鑑み、本発明の目的は、複数のアダプタが高密度に設けられている場合でも目的の光コネクタを間違えることがなく、コード部分を挟持する誤操作を防止し、隣接する光コネクタや光コードを損傷させることなく目的の光コネクタを確実に着脱することができるコネクタ着脱工具を提供することである。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、光コネクタをアダプタに着脱するためのコネクタ着脱工具において、光コネクタの両側面を挟持するための１対の挟持片と、挟持片を開閉操作するためのレバー部と、光コードを挿通させて工具を光コネクタまで案内させるためのガイド部と、挟持片の間に前後動可能に設けられ、前部に位置する場合は挟持片が閉塞できないようにし、後部に位置する場合は挟持片が閉塞できるようにするストッパー部と、ストッパー部を挟持片の前部方向に付勢する弾性部材と、挟持片の開放幅を制限する係止腕部とを備えたことを特徴とする。
【０００７】
【発明の実施の形態】
コネクタ着脱工具は光コネクタの両側面を挟持するための１対の挟持片と、挟持片を開閉操作するためのレバー部と、光コードを挿通させてコネクタ着脱工具を光コネクタまで案内させるためのガイド部と、挟持片の間に前後動可能に設けられ、前部に位置する場合は挟持片が閉塞できないようにし、後部に位置する場合は挟持片が閉塞できるようにするストッパー部と、ストッパー部を挟持片の前部方向に付勢する弾性部材と、挟持片の開放幅を制限する係止腕部とを備えている。
【０００８】
【実施例】
本発明に係るコネクタ着脱工具の実施例を図１〜図３の添付図面に基づいて説明する。
【０００９】
コネクタ着脱工具１は、光コネクタ２の両側面を挟持するための１対の挟持片３と、挟持片３の基端に一体に設けられ、挟持片３を開閉操作するためのレバー部４と、挟持片３を開閉する際に支点となる枢軸５と、挟持片３の間に前後動可能に設けられたストッパー部６と、ストッパー部６に形成され、光コード７を挿通させる凹溝状のガイド部８と、ストッパー部６と一体に棒状に形成され、枢軸方向に延びる可動軸部９と、可動軸部９を摺動可能に保持するために可動軸部９の端部が挿入される挿入穴１０を形成した保持部１１と、可動軸部９の外周に突設された鍔部１２と、この鍔部１２と保持部１１の挿入穴１０の穴奥部との間に可動軸部９を貫通させて設けられ、ストッパー部６を挟持片３の前部方向（先端方向）へ付勢するための弾性部材としてのコイルバネ１３と、挟持片３と一体に形成され、可動軸部９の鍔部１２に係止して可動軸部９が保持部１１の挿入穴１０から飛び出さないようにするための突起部１４と、保持部１１の左右両側から突設され、挟持片３の側面に係止して挟持片３の開放幅を制限するための係止腕部１５とで構成している。
【００１０】
ストッパー部６はコイルバネ１３の力によって挟持片３の前部（先端側）に位置する場合は挟持片３が閉塞できないようにし、ストッパー部６の先端をコイルバネ１３の力に抗して押し込み、ストッパー部６が挟持片３の後部（基端側）に位置する場合は挟持片３が閉塞できるようになっている。このため、挟持片３の先端側の間隔はストッパー部６の側面に当接するように狭く形成され、基端側の間隔はストッパー部６を逃がすために広く形成されている。また、挟持片３の開放幅は係止腕部１５により制限しているが、この開放幅は光コネクタ２の幅寸法より僅かに大きく、隣接する光コネクタ２に接触しない寸法としている。
【００１１】
アダプタ１６から光コネクタ２を抜き取るには、まず、光コード７に表示されている系統番号を見ながら目的の光コネクタ２の光コード７を探してストッパー部６のガイド部８に挿通させる。そして、光コード７に沿ってコネクタ着脱工具１を光コネクタ２に当接するまで移動させ、コネクタ着脱工具１のストッパー部６が光コネクタ２まで到達したら、そこからストッパー部６の先端面を光コネクタ２に当接させた状態で更にコネクタ着脱工具１を押し込む。すると、コイルバネ１３の力に抗して保持部１１の挿入穴１０に可動軸部９が引き込まれ、ストッパー部６が挟持片３の前部から後部に移動する。これにより、レバー部４を操作して挟持片３を閉塞できるようになる。そこでレバー部４を握ると挟持片３が光コネクタ２の側面を挟持し、その状態のままコネクタ着脱工具１を引き抜くとアダプタ１６から光コネクタ２を取り外すことができる。その後、レバー部４を開くと挟持片３が開放してコネクタ着脱工具１から光コネクタ２が外れ、同時にストッパー部６がコイルバネ１３のバネ力によって元の位置に戻る。
【００１２】
また、アダプタ１６に光コネクタ２を接続するには、光コード７をストッパー部６のガイド部８に挿通させてからストッパー部６を指で押し込み、レバー部４を握って光コネクタ２を挟持片３で挟持する。そして、その状態で光コネクタ２を目的のアダプタ１６に差し込んで接続する。
【００１３】
尚、光コネクタ着脱工具の形状について限定はなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００１４】
【発明の効果】
以上説明したように、光コネクタをアダプタに着脱するためのコネクタ着脱工具において、光コネクタの両側面を挟持するための１対の挟持片と、挟持片を開閉操作するためのレバー部と、光コードを挿通させて工具を光コネクタまで案内させるためのガイド部と、挟持片の間に前後動可能に設けられ、前部に位置する場合は挟持片が閉塞できないようにし、後部に位置する場合は挟持片が閉塞できるようにするストッパー部と、ストッパー部を挟持片の前部方向に付勢する弾性部材と、挟持片の開放幅を制限する係止腕部とを備えたことにより、光コネクタまでガイド部によって案内するので目的の光コネクタを間違えることがなく、工具が光コネクタに到達しないと挟持できないのでコード部分を挟持する誤操作を防止でき、隣接する光コネクタに挟持片が当たらないので光コネクタや光コードを損傷させることがなく、よって複数のアダプタが高密度に設けられている場合でも目的の光コネクタを確実に着脱することができるという効果がある。

[0008]
【Example】
An embodiment of a connector attaching / detaching tool according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0009]
The connector attaching / detaching tool 1 includes a pair of sandwiching pieces 3 for sandwiching both side surfaces of the optical connector 2, and a lever portion 4 that is integrally provided at the proximal end of the sandwiching piece 3 and that opens and closes the sandwiching piece 3. The pivot 5 serving as a fulcrum when the clamping piece 3 is opened and closed, the stopper portion 6 provided between the clamping pieces 3 so as to be movable back and forth, and the concave groove shape into which the optical cord 7 is inserted. The guide portion 8 and the stopper portion 6 are integrally formed in a rod shape, and the movable shaft portion 9 extending in the axial direction and the end portion of the movable shaft portion 9 are inserted to hold the movable shaft portion 9 slidably. The movable portion 11 is formed between the holding portion 11 in which the insertion hole 10 is formed, the flange portion 12 protruding from the outer periphery of the movable shaft portion 9, and the deep portion of the insertion hole 10 of the holding portion 11. For urging the stopper portion 6 in the front direction (front end direction) of the sandwiching piece 3 provided through the portion 9 In order to prevent the movable shaft portion 9 from jumping out from the insertion hole 10 of the holding portion 11 by being integrally formed with the coil spring 13 as the elastic member and the sandwiching piece 3 and being locked to the flange portion 12 of the movable shaft portion 9. And a locking arm portion 15 that protrudes from the left and right sides of the holding portion 11 and is locked to the side surface of the holding piece 3 to limit the opening width of the holding piece 3.
[0010]
When the stopper portion 6 is positioned at the front portion (front end side) of the holding piece 3 by the force of the coil spring 13, the holding piece 3 is prevented from being closed, and the tip of the stopper portion 6 is pushed against the force of the coil spring 13 to stop the stopper piece 6. When the part 6 is located at the rear part (base end side) of the sandwiching piece 3, the sandwiching piece 3 can be closed. For this reason, the space | interval of the front end side of the clamping piece 3 is formed so that it may contact | abut to the side surface of the stopper part 6, and the space | interval of the base end side is formed widely in order to let the stopper part 6 escape. Further, the opening width of the sandwiching piece 3 is limited by the locking arm portion 15, but this opening width is slightly larger than the width dimension of the optical connector 2 and does not contact the adjacent optical connector 2.
[0011]
In order to remove the optical connector 2 from the adapter 16, first, the optical cord 7 of the target optical connector 2 is searched while looking at the system number displayed on the optical cord 7, and is inserted into the guide portion 8 of the stopper portion 6. Then, the connector attaching / detaching tool 1 is moved along the optical cord 7 until it abuts against the optical connector 2. When the stopper portion 6 of the connector attaching / detaching tool 1 reaches the optical connector 2, the tip end surface of the stopper portion 6 is moved from there to the optical connector. Further, the connector attaching / detaching tool 1 is pushed in a state where it is brought into contact with 2. Then, the movable shaft portion 9 is drawn into the insertion hole 10 of the holding portion 11 against the force of the coil spring 13, and the stopper portion 6 moves from the front portion of the sandwiching piece 3 to the rear portion. Thereby, the lever part 4 can be operated and the clamping piece 3 can be obstruct | occluded. Therefore, when the lever portion 4 is grasped, the holding piece 3 holds the side surface of the optical connector 2, and the optical connector 2 can be detached from the adapter 16 by pulling out the connector attaching / detaching tool 1 in this state. Thereafter, when the lever portion 4 is opened, the clamping piece 3 is opened, the optical connector 2 is detached from the connector attaching / detaching tool 1, and at the same time, the stopper portion 6 is returned to the original position by the spring force of the coil spring 13.
[0012]
In order to connect the optical connector 2 to the adapter 16, the optical cord 7 is inserted into the guide portion 8 of the stopper portion 6, and then the stopper portion 6 is pushed with a finger, and the lever portion 4 is grasped to hold the optical connector 2. 3 to hold. In this state, the optical connector 2 is inserted and connected to the target adapter 16.
[0013]
The shape of the optical connector attaching / detaching tool is not limited, and can be appropriately changed without departing from the spirit of the present invention.
[0014]
