Description

【0001】
【発明の属する技術分野】
本発明は、レセプタクルに対し、光プラグを着脱するのに用いられる工具に関する。
【0002】
【従来の技術】
従来、光プラグ着脱専用工具としては、基部を把持部とした本体の上下(左右)両側部に、二個一対のレバーを、その略中間部を枢着して開閉自在に配設すると共に、該一対のレバーには、その先端部のプラグクランプ部が閉じる方向に、介在したバネによるバネ力を付勢してなるものが知られている。
【0003】
【発明が解決しようとする課題】
しかし乍ら、上記従来のプラグ着脱工具は、本体及び一対のレバーが金属製のため絶縁性が悪く、また、一対のレバーが必要である分、構造的に複雑で大型で重く、かつプラグ着脱時、レバーの操作が必要であるため、操作性が悪い上、高価である等の問題がある。
【0004】
【目的】
本発明は、上記した従来のプラグ着脱工具が有するこのような問題点に鑑みてなされたもので、プラスチックで一体成形が可能であるため、絶縁性に優れると共に、大量生産が可能で安価であり、また軽量で操作性が良く、使い勝手の良い光プラグ着脱工具を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記目的を達成するために、本発明に係る光プラグ着脱工具は、光ファイバーケーブルの端部に取り付けられた光プラグをレセプタクルに対して着脱するのに用いられ、プラスチックにて一体に成形された光プラグ着脱工具であって、
上向きの開口部を有する凹溝条に形成した本体の長尺方向先端部に、プラグフレームの左右に対称に開設した係止孔と係合する係合突起を対向突設した弾性を有する二個一対のクランプ板を所定の間隔をおいて平行に突設し、前記各係合突起は、その上部及び後部を前記係止孔の開口縁と各係止すべくクランプ板内面に対して垂直に形成された係止面と、前記各係合突起の前部及び下部を当該係合突起先端側から各クランプ板内面側に向けて前方及び下方へ傾斜下降するように形成された傾斜面とを備え、
プラグフレームに対し、本体を前方へ押し込むことで、前記係合突起の前部傾斜面がプラグフレームにおける後端左右両角部に突き当って滑動し、二個一対のクランプ板が外側へ対称に押し広げられ、各係合突起がプラグフレーム左右の係止孔に嵌合することで本体がプラグフレームに外装され、
各係合突起が各係止孔に係合して本体がプラグフレームに嵌合された状態から、プラグフレームを水平状態に保ったまま本体の開口部上方に引張ることで、プラグフレームの係止孔開口縁が係合突起の下部傾斜面と当接して互いに滑動することで、二個一対のクランプ板は外側へ対称に押し広げられて各係止孔と各係合突起の係合が外され、本体がプラグフレームから取り外されるように各形成したことを特徴とする。
【0006】
【作用】
プラグがレセプタクルに嵌合実装されている状態で、該プラグ後部に対し、工具を同軸上において、その先端部を押し込むと、二個一対のクランプ板に対向突設した二個の係合突起の前部傾斜面がプラグフレーム後端の左右角部と突き当る。そこで、さらに工具を押し込むと、上記傾斜面が上記左右角部を滑動して押し込まれることで、二個一対のクランプ板は外側へ対称に、自体の有する弾発力に抗して押し広げられて押し込まれ、両係合突起はプラグフレーム上に乗り上がり、さらに、工具が押し込まれて両係合突起が、プラグフレームの係止孔に一致すると、クランプ板が内側へ水平に弾性復帰し、各係合突起は、プラグフレーム左右の係止孔に嵌合する。
【0007】
次いで、工具を後方へ引張ることで、当該工具と一体となってプラグはレセプタクルから引き抜かれる。
引き抜かれたプラグを工具から外す際は、プラグを水平状態に保ったまま工具の開口部上方に引張ると、プラグフレームの係止孔開口縁が係合突起の下部傾斜面と当接し、互いに滑動することで、二個一対のクランプ板は外側へ対称に押し広げられ、プラグフレームの左右外側面に各係合突起は乗り上がり、さらにプラグを上方へ引張ることで該プラグを工具の上方開口部から外すことができる。
プラグが工具から取り外されることで、二個一対にクランプ板は、自体の弾性により内側へ水平に復帰する。
【0008】
また、工具の先端にプラグを係合保持した状態で、工具よりプラグをレセプタクルに押し込むことによって、該プラグをレセプタクルに嵌合することができる。
【0009】

BACKGROUND OF THE INVENTION
The present invention relates to a tool used for attaching / detaching an optical plug to / from a receptacle.
[0002]
[Prior art]
Conventionally, as an optical plug attaching / detaching tool, a pair of two levers are pivotally attached to both upper and lower (left and right) side portions of the main body with the base as a gripping portion, and can be freely opened and closed with its substantially middle portion pivoted. As the pair of levers, a lever formed by biasing a spring force by an interposed spring is known in the direction in which the plug clamp portion at the tip end is closed.
[0003]
[Problems to be solved by the invention]
However, the above conventional plug attaching / detaching tool has poor insulation because the main body and the pair of levers are made of metal, and is structurally complex, large and heavy, and requires only a pair of levers. Since the operation of the lever is necessary, there are problems such as poor operability and high cost.
[0004]
【the purpose】
The present invention has been made in view of the above-described problems of the conventional plug attaching / detaching tool described above, and can be integrally molded with plastic, so that it has excellent insulation properties, is mass-produced, and is inexpensive. It is another object of the present invention to provide an optical plug attaching / detaching tool that is lightweight, easy to operate and easy to use.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, an optical plug attaching / detaching tool according to the present invention is used for attaching / detaching an optical plug attached to an end of an optical fiber cable to / from a receptacle, and is a light integrally formed of plastic. A plug detaching tool,
Two elastically projecting engagement protrusions that are engaged with engagement holes provided symmetrically on the left and right sides of the plug frame at the front end in the longitudinal direction of the main body formed in a groove groove having an upward opening. A pair of clamp plates are projected in parallel at a predetermined interval, and each of the engaging projections is perpendicular to the inner surface of the clamp plate so as to lock the upper and rear portions thereof with the opening edge of the locking hole. A locking surface that is formed, and an inclined surface that is formed so that the front and lower portions of each engagement protrusion are inclined downward and forward from the front end side of the engagement protrusion toward the inner surface side of each clamp plate. Prepared,
When the main body is pushed forward against the plug frame, the front inclined surface of the engaging projection slides against the left and right corners of the rear end of the plug frame, and the two clamp plates are pushed symmetrically outward. The main body is externally attached to the plug frame by expanding each engagement protrusion into the engagement holes on the left and right of the plug frame,
From the state where each engaging projection engages with each locking hole and the main body is fitted in the plug frame, the plug frame is locked by pulling the plug frame above the opening of the main body while maintaining the horizontal state. When the hole opening edge abuts against the lower inclined surface of the engagement protrusion and slides on each other, the two clamp plates are symmetrically pushed outward and the engagement between the engagement holes and the engagement protrusions is released. Each body is formed so as to be detached from the plug frame.
[0006]
[Action]
When the tool is coaxially inserted into the rear portion of the plug while the plug is fitted and mounted on the receptacle, the two engaging projections projecting from the two clamp plates are projected. The front slope faces the left and right corners at the rear end of the plug frame. Therefore, when the tool is further pushed in, the inclined surface slides and pushes in the left and right corners, so that the two pairs of clamp plates are symmetrically spread outwardly against the elastic force that they have. When the tool is pushed in and both engaging protrusions match the locking holes of the plug frame, the clamp plate elastically returns to the inside horizontally, Each engagement protrusion fits into the engagement holes on the left and right of the plug frame.
[0007]
Next, by pulling the tool backward, the plug is pulled out of the receptacle together with the tool.
When removing the pulled plug from the tool, if the plug is pulled horizontally above the tool opening while keeping the plug in a horizontal state, the opening edge of the locking hole of the plug frame abuts against the lower inclined surface of the engaging protrusion and slides on each other. As a result, the pair of clamp plates are symmetrically pushed outward, the respective engaging projections ride on the left and right outer surfaces of the plug frame, and the plug is pulled upward to pull the plug upward in the tool opening. Can be removed.
When the plug is removed from the tool, the pair of clamp plates return horizontally inward due to their elasticity.
[0008]
Further, the plug can be fitted into the receptacle by pushing the plug into the receptacle from the tool while the plug is engaged and held at the tip of the tool.
[0009]

Two elastically projecting engagement protrusions that are engaged with engagement holes provided symmetrically on the left and right sides of the plug frame at the front end in the longitudinal direction of the main body formed in a groove groove having an upward opening. A pair of clamp plates are projected in parallel at a predetermined interval, and each of the engaging projections is perpendicular to the inner surface of the clamp plate so as to lock the upper and rear portions thereof with the opening edge of the locking hole. A locking surface that is formed, and an inclined surface that is formed so that the front and lower portions of each engagement protrusion are inclined downward and forward from the front end side of the engagement protrusion toward the inner surface side of each clamp plate. Prepared,
When the main body is pushed forward against the plug frame, the front inclined surface of the engaging projection slides against the left and right corners of the rear end of the plug frame, and the two clamp plates are pushed symmetrically outward. The main body is externally attached to the plug frame by expanding each engagement protrusion into the engagement holes on the left and right of the plug frame,
From the state where each engaging projection engages with each locking hole and the main body is fitted in the plug frame, the plug frame is locked by pulling the plug frame above the opening of the main body while maintaining the horizontal state. When the hole opening edge abuts against the lower inclined surface of the engagement protrusion and slides on each other, the two clamp plates are symmetrically pushed outward and the engagement between the engagement holes and the engagement protrusions is released. And an optical plug attaching / detaching tool formed so that the main body is removed from the plug frame.
