〈産業上の利用分野〉
本発明は光ファイバ同士の接続に用いるコネクタに係わ
り、より詳しくは耐久性に優れた光ファイバ用コネクタ
に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a connector used for connecting optical fibers, and more particularly to an optical fiber connector with excellent durability.
〈従来の技術〉
光ファイバ同士の接続法として、着脱が可能で、接続作
業が簡単なコネクタによる接続法がある。<Prior Art> As a method of connecting optical fibers, there is a method of connecting optical fibers using a connector that is detachable and easy to connect.
このコネクタによる接続法の一つに、ガイドピンをガイ
ドピン固定部材にて一方のコネクタに挾み込んで固定し
、該ガイドピンを他方のコネクタに設けられたガイド孔
に嵌入させることにより、コネクタ同士の接続を行う接
続法がある。One of the connection methods using this connector is to insert and fix a guide pin into one connector using a guide pin fixing member, and then insert the guide pin into a guide hole provided in the other connector. There is a subjunctive method that connects them.
従来、ガイドピン固定部材は、金属材料を精密切削加工
して作製したものが主流を占めていた。Conventionally, guide pin fixing members have been mainly manufactured by precision cutting metal materials.
しかし、ガイドピン固定部材はミクロン単位の寸法精度
で精密加工する必要があるにもががゎらず、金属材料で
は加工誤差によってコアの軸ずれ、角度ずれ等が生じ、
接続部における光伝送損失（以下、「接続損失」という
）が多いものが作製される場合があった。However, the guide pin fixing member needs to be precisely machined with dimensional accuracy in the micron level, and with metal materials, machining errors can cause core axis misalignment, angular misalignment, etc.
In some cases, a device with a large optical transmission loss (hereinafter referred to as "connection loss") at the connection portion was manufactured.
そこで、近年、加工精度を向上させるため、金属材料に
代わるものとして精密加工に好適なシリコン等のセラミ
ックがガイドピン固定部材の材料として実用化されてい
る。Therefore, in recent years, in order to improve machining accuracy, ceramics such as silicon, which are suitable for precision machining, have been put into practical use as materials for guide pin fixing members in place of metal materials.
〈発明が解決しようとする課題〉
しかしながら、上記従来の光ファイバ用コネク夕には、
ガイドピン固定部材の素材として用いるセラミックが脆
くて強度が充分でなく、接続の際、ガイドピンを介して
加えられる外力により簡単にひび割れしたり、表面にク
ラックが生じたりするため、耐久性が良くないと共に、
これらひび割れ等によりコア軸のずれ等が生じ、損失の
少ない光伝送を行うことができないという問題があった
。<Problem to be solved by the invention> However, the conventional optical fiber connector described above has the following problems:
The ceramic used as the material for the guide pin fixing member is brittle and does not have sufficient strength, and when connected, it easily cracks or cracks occur on the surface due to external force applied through the guide pin. With no,
There is a problem in that these cracks cause misalignment of the core axis, making it impossible to perform optical transmission with little loss.
本発明は、上記問題を解決するためになされたものであ
って、その目的とするところは、加工精度を向上させる
ためにセラミック等の精密加工に適した部材にて作製さ
れたガイドビン固定部材の脆さに起因するひび割れ及び
クラックが生じることのないコネクタを提供することに
ある。The present invention has been made in order to solve the above-mentioned problems, and its purpose is to provide a guide bin fixing member made of a material suitable for precision machining, such as ceramic, in order to improve machining accuracy. An object of the present invention is to provide a connector that is free from cracks and cracks caused by the fragility of the connector.
く課題を解決するための手段〉
上記目的を達成するべくなされた本発明に係る光ファイ
バ用コネクタは、少なくとも前記ガイドビン固定部材の
ガイドピンが当接する面に、軟質の有機膜が形成されて
いることを特徴とする。Means for Solving the Problems> The optical fiber connector according to the present invention, which has been made to achieve the above object, has a soft organic film formed at least on the surface of the guide bin fixing member that the guide pin contacts. It is characterized by the presence of
上記有機膜の素材としては、ポリエチレン、ポリテトラ
フルオロエチレン、ポリイミド、ポリフ二二しンサルフ
ァイドが例示されるが、軟質膜を形成し得るものであれ
ば特に限定されない。Examples of the material for the organic film include polyethylene, polytetrafluoroethylene, polyimide, and polyphenylene sulfide, but the material is not particularly limited as long as it can form a soft film.
上記有機膜の膜厚は１〜５０μ−程度が好ましい。The thickness of the organic film is preferably about 1 to 50 μm.
これは、膜厚が１μｍ未満であると、有機膜の緩衝層と
しての効果を充分期待できなくなるからであり、５０μ
ｍを越えると、軸ずれ等が大きくなり接続損失が多くな
るからである。This is because if the film thickness is less than 1 μm, the effect of the organic film as a buffer layer cannot be expected to be sufficient;
This is because if it exceeds m, axis misalignment, etc. will become large and connection loss will increase.
上記有機膜を形成する好適な手段としては、電界脱離法
を例示することができる。塗布法によることも可能では
あるが、ピンホールの少ない高品質の膜を形成し得る点
で電界脱離法が好ましい。An example of a suitable means for forming the organic film is an electric field desorption method. Although it is possible to use a coating method, the electric field desorption method is preferable because it can form a high-quality film with few pinholes.
電界脱離法は、先端の尖鋭部に有機物を塗布した加熱に
耐え得る針金、カミソリ等を一方の電極として配すると
共に、対向電極を空間を隔てて配し、これら両電極間に
高電圧を印加して１０８Ｖ／（至）程度以上の強い電界
を発生させ、徐々に昇温し、発生した電界の吸引力によ
り、加熱溶融した有機物をいわゆる分子イオン又は帯電
粒子として溶融相から気相に飛散させ、この飛散物を上
記電界の作用によりガイドビン固定部材の表面に運び、
そこに膜を析出形成する方法である。In the electric field desorption method, a wire, razor, etc. that can withstand heating and whose sharp tip is coated with an organic substance is placed as one electrode, an opposing electrode is placed with a space between them, and a high voltage is applied between these two electrodes. A strong electric field of about 108 V/(max) is applied, the temperature is gradually raised, and the attractive force of the generated electric field causes the heated and melted organic matter to scatter from the molten phase to the gas phase as so-called molecular ions or charged particles. The scattered objects are carried to the surface of the guide bin fixing member by the action of the electric field,
This method involves depositing and forming a film there.
上記飛散物には、極微細なジェット状の帯電した液滴と
して飛散するものと、分子状のいわゆる分子イオンとし
て飛散するものとがあり、電界脱離法は両爪散物を共に
シリコン等のガイドビン固定部材に導いて膜形成をなす
ので、膜形成効率の高い方法であると言える。The above-mentioned scattered particles include those that scatter as ultrafine jet-shaped charged droplets and those that scatter as molecular ions, and the electric field desorption method can remove both types of scattered particles such as silicon. Since the film is formed by guiding it to the guide bin fixing member, it can be said that it is a method with high film formation efficiency.
く作用〉
本発明に係る光ファイバ用コネクタの有機膜で被覆され
ているガイドビン固定部材にガイドピンを介して外力が
作用すると、有機膜が緩衝層として衝撃を吸収し、これ
によりコネクタのひび割れ、クラック等の亀裂の発生が
阻止される。Effect> When an external force acts on the guide bin fixing member covered with the organic film of the optical fiber connector according to the present invention via the guide pin, the organic film absorbs the impact as a buffer layer, thereby preventing cracks in the connector. , the occurrence of cracks such as cracks is prevented.
