れ等が付着していると接続特性が劣化する。<Prior Art> Conventionally, various optical connectors have been used to easily connect and disconnect optical fibers, but the mainstream is, for example, F01 type single-core optical fiber specified in JIS C5970. Like a connector, this is a method in which an optical fiber is fixed to the center of a cylindrical rod (ferrule), this is inserted into a hollow cylinder (alignment sleeve) having a precise inner diameter, and the end faces of the ferrule are abutted against each other. The optical connector of such a method is widely used especially in the field of optical communication because it has excellent connection characteristics.However, since the end faces of the optical fibers are directly abutted with each other, dust or oil stains are attached to the ferrule end face. Connection performance deteriorates.

面に吹き付ける作業を行っている。Therefore, it is necessary to clean the end surface of the ferrule before the connection work. In the conventional case, as shown in FIG.
As shown in (b), first, the ferrule of the optical connector 01.
The end surface of 02 is wiped with a soft cloth or paper piece 03 containing ethanol, and then a freon gas or the like 04 is sprayed on the end surface of the ferrule 02 in order to remove residual ethanol and scraps of the cloth or paper piece.

題がある。<Problems to be Solved by the Invention> However, in the above-described cleaning work, the work is complicated, and water may be attached to the end surface of the ferrule 02 due to the heat of vaporization of ethanol. If the cylinder is used upside down, there is a problem that it spouts in a liquid state and the end surface of the ferrule 02 is replaced and soiled.
本発明はこのような事情に鑑み、簡単な操作で光コネ

Tape-like cleaning cloth made of cloth woven with ultrafine fibers, a cleaning cloth moving part where an unused part is exposed by manipulating the cleaning cloth, and the back side of the cleaning cloth where the ferrule end surface is cleaned. The ferrule has an elastic member that receives a force for pressing the cleaning cloth, and the elastic member is provided with a groove having a width approximately equal to the outer diameter of the ferrule to be cleaned.

As it consists of a cloth woven with ultrafine fibers of 1 denier or less,
Even if a solvent such as ethanol is not used, oil stains such as fingerprints attached to the end surface can be removed by dry wiping. Further, since the elastic member that receives the force pressing the cleaning cloth by the ferrule is in contact with the back surface side of the portion for cleaning the end surface of the ferrule, the contact between the ferrule and the cleaning cloth becomes strong. Further, since the groove is formed in the elastic body, not only the end face of the ferrule but also the side face near the end face can be cleaned.
清浄は清浄布の未使用部分で行うのがよいが、清浄布

る。FIG. 1 is a perspective view showing a cleaning tool for an optical connector according to an embodiment. As shown in the figure, a tape-shaped cleaning cloth 3 for cleaning the end surface of the ferrule 2 of the optical connector 1 is wound around a winding reel 4 and wound around a pair of guide reels 5, 5. After that, the film is taken up by the take-up reel 6. A support member 7 is provided on the back surface side of the cleaning cloth 3 between the pair of guide reels 5, 5.
本実施例では清浄布3として市販のミラクレーション
(東レ株式会社製)のポリエステル系の布を用いてい
る。この清浄布3は約0.1デニール以下の極細繊維で織
られた布であれば材質は特に限定されず、ポリエステル
系の他、ナイロン系などを用いればよい。In this embodiment, as the cleaning cloth 3, a commercially available Miracle (manufactured by Toray Industries, Inc.) polyester cloth is used. The material of the cleaning cloth 3 is not particularly limited as long as it is a cloth woven with ultrafine fibers having a density of about 0.1 denier or less, and nylon or the like may be used in addition to polyester.
このような構成の光コネクタの清浄器具を使用するに
は、まず、巻取りリール6を回動させて清浄布3の未使
用部分を支持部材7の上に位置する。そして、光コネク
タ1を支持板7上の清浄布3に押付けながら前後左右に
動かすことにより、フェルール2の端面を清浄する。In order to use the optical connector cleaning instrument having such a configuration, first, the take-up reel 6 is rotated to position the unused portion of the cleaning cloth 3 on the support member 7. Then, the optical connector 1 is moved to the front, rear, left and right while being pressed against the cleaning cloth 3 on the support plate 7 to clean the end face of the ferrule 2.
この清浄の都度、巻取りリール6を回動するようにし

保証される。また、巻付けリール4及び巻取りリール6
にラチェット機構を設けておき、各リールの逆回転を防
ぐようにして支持部材7上に清浄布3の汚れた部分が移
動しないようにすることもできる。By rotating the take-up reel 6 every time this cleaning is performed so that the unused cleaning cloth 3 is always positioned on the support member 7, the end face of the ferrule can be always cleaned with a new surface. After the cleaning operation, it is guaranteed that the ferrule end surface is surely cleaned without checking the condition of the end face with a microscope or the like. Further, the winding reel 4 and the winding reel 6
It is also possible to provide a ratchet mechanism in the above to prevent the reels from rotating in the reverse direction so that the dirty portion of the cleaning cloth 3 does not move on the support member 7.
ここで、支持部材7はフェルール2の端面を良好に清

ことにより、フェルール2を押し付けながら清浄布3を
動かして清浄作業を行う場合に、清浄布3と支持部材7C
との摩擦を小さくすることができ、有効である。Here, in order to clean the end surface of the ferrule 2 favorably, the support member 7 is preferably made of an elastic body having a large elasticity such as rubber, but of course, even a hard material can be cleaned. The shape of the support member 7 is shown in FIG.
As shown in (c), a plate-shaped support member having a flat surface
In addition to 7A, a groove with the same width as the outer diameter of the ferrule 2 to be cleaned
It may be a support member 7B having 8a. In this case, by moving the ferrule 2 along the groove 8a, not only the end face of the ferrule 2 but also the side face near the tip can be cleaned. Furthermore, since the elongation of the cloth when the ferrule 2 is pressed against the clean cloth 3 can be absorbed by the shape of the groove 8a, when the ferrule 2 is moved while being pressed against the cloth, it is less likely to be caught due to partial slack of the cloth. ,
Cleaning work becomes easier. Further, the support member may have a cylindrical shape, for example, a support member 7C having a groove 8b having the same function as the groove 8a of the support member 7B on the peripheral surface. When such a cylindrical support member 7C is rotatably supported and used, when the cleaning work is performed by moving the cleaning cloth 3 while pressing the ferrule 2, the cleaning cloth 3 and the supporting member 7C are
It is effective because it can reduce the friction with.
なお、このような支持部材7は必ずしも必要でなく、
例えば清浄布3に適当な張力を与えておけば、支持部材
7がないところにフェルール2を押し付けながら前後左
右に動かすことにより清浄作業が可能となる。In addition, such a supporting member 7 is not always necessary,
For example, if an appropriate tension is applied to the cleaning cloth 3, the cleaning work can be performed by pressing the ferrule 2 in the place where the supporting member 7 is not present and moving it back and forth and right and left.

2の端面は清浄される。FIG. 3 shows an example in which a holding tool is provided in a cleaning tool similar to that shown in FIG. 1, and a cleaning mechanism for moving the holding tool and the cleaning cloth relatively. As shown in the figure,
Reference numeral 10 denotes a holder for the optical connector 1, which is fixed to a frame (not shown). On the other hand, a support frame 11 that rotatably supports a pair of guide reels 5, 5 that guide the cleaning cloth 3 is axially movable to a frame (not shown) through a shaft 12 that is fixed through the support frame 11. It is supported.
An engaging member 13 is provided on the side surface of the support frame 11 in a protruding manner, and the engaging member 13 has a long hole long in the direction orthogonal to the shaft 12.
13a is formed, and the eccentric shaft 14 is engaged with the elongated hole 13a. The eccentric shaft 14 is projectingly provided on a peripheral portion of a gear 17 that meshes with a pinion 16 attached to a drive shaft of a motor 15, and is centered on a shaft 18 rotatably provided on a frame (not shown) by driving the motor 15. It moves with the rotating gear 17 and makes a circular motion. The movement of the eccentric shaft 14 causes the support frame 11 to reciprocate in the direction of the shaft 12, and the cleaning cloth 3 guided by the guide reels 5 and 5 reciprocates in the width direction, and the optical connector held by the holder 10. It moves relative to ferrule 2 of 1. As a result, the end surface of the ferrule 2 is cleaned.

2の端面が清浄されるようになっている。A worm 19 is provided on a shaft 18 that supports the gear 17, while a worm wheel 20 is fixed to a shaft (not shown) that rotates together with the take-up reel 6 for the cleaning cloth 3. Therefore, the take-up reel 6 is rotated along with the cleaning work by driving the motor 15, and the end face of the ferrule 2 is constantly cleaned with the new cleaning cloth 3.
