〔産業上の利用分野〕
本発明は、光通信に用いる光ファイバーを接続するコネ
クタに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector for connecting optical fibers used in optical communications.

行われている。The core parts of the two are aligned and connected to guide light.
このようにコネクタの主要部を成す整合スリーブ２は主

求される。As described above, the matching sleeve 2, which forms the main part of the connector, is mainly made of a copper alloy such as phosphor bronze, and the material for forming the ferrule 2 is mainly ceramic or stainless steel. When connecting optical fibers using such a p-connector, in order to minimize the optical connection loss, the deviation between the fibers F+ and Fz should be kept to about 1 μm or less, and the deviation in the end face angles of the fibers F, , F should be kept to 0. In order to make the angle less than 5 degrees, extremely high accuracy is required in terms of surface roughness, straightness, and roundness of the inner wall surface of the sleeve 2.

半径方向のバネ性を備えたものが使用さている。In addition, when inserting the ferrules V, Vt into the matching sleeve 2, it enables smooth insertion, adds an appropriate holding force to the inserted ferrules V, Vt,
Furthermore, in order to absorb external mechanical impact force and maintain stable connection performance, the alignment sleeve 2 is particularly provided with radial spring properties.

かった。However, when the matching sleeve is made of phosphor bronze as described above, when inserting the ferrule, scratches may occur on the inner wall surface of the matching sleeve due to adhesion or contamination of the ferrule, or the insertion angle may be incorrect. This may cause deformation of the alignment sleeve, and if it is repeatedly attached and detached over a long period of time, the retaining force of the alignment sleeve may decrease, and if it is exposed to air for a long period of time, the inner wall surface may become deformed. There is a strong possibility that the above-mentioned phenomena, such as the formation of an oxide film, may degrade connection performance or significantly impair stability, either singly or in combination.

る。FIG. 2(a) is a cutaway view of only the matching sleeve 20, which constitutes the main part of the connector according to the present invention. A ferrule into which a fiber is inserted and fixed is inserted from both opening ends, and the inner wall surface 22 forming this inner space 21 is polished with extremely high precision, and there are slits in the longitudinal direction to generate elasticity. 23 is the formation.

、第１表にこの種のジルコニアセラミックと従来の整合
スリーブを構成していたリン青銅の特性を示す。By the way, the alignment sleeve 20 according to the present invention is made of ceramic materials, especially zirconia ceramic, and this zirconia ceramic contains zirconium oxide (ZrO□) and yttria (Y2O) as a sintering aid.

表面における物理的、化学的変化を来すことはない。In this way, zirconia ceramic is approximately 6 times harder than Rin S, and therefore has a higher hardness than the peeling powder of the nickel plating applied to the connector casing and the dust that scatters and gets mixed in. Therefore, it is difficult for the inner wall surface 22 of the alignment sleeve 20 to suffer from scratches and the accompanying wear. In addition, the Young's modulus of zirconia ceramic is approximately 1.5 times higher than that of phosphor bronze.As for the coefficient of zero-order linear expansion, zirconia ceramic is approximately 0 times higher than that of phosphor bronze.
．． It is six times smaller, so the alignment sleeve 20 made of zirconia ceramic has a stable holding force against temperature. Further, since zirconia ceramic is an oxide, it is not oxidized in the air and has high corrosion resistance, so that no physical or chemical changes occur on the surface of the inner wall surface 22 of the matching sleeve 20.

る接続性能が低下することはない。Due to the above characteristics, by setting the surface roughness, inner diameter, and outer diameter dimensions of the inner wall surface 22 of the alignment sleeve 20, the inserted ferrule is provided with a holding force, and as a result, it is difficult to cause scratches and deformation, and can be used for a long period of time. However, the connection performance will not deteriorate due to a decrease in holding force or deterioration of quality.

たものである。Next, FIG. 2 shows the relationship between the inner diameter dimension of the alignment sleeve 20 and the ferrule removal force. In this case, the outer diameter is 2.499 mm.
Insert a ferrule of +0.001 to 0III11 from one direction, insert a ferrule of the same size from the other open end, and with the tip surfaces of the ferrules in contact with each other at the center of the matching sleeve, - This is a plot of the force required to fix one ferrule and remove the other ferrule. Figure 2 shows the design based on the inner diameter range that has the optimal holding force determined from Figure 3. A matching sleeve 20 of the shape shown and having the specifications described above.

もとに行った結果をそれぞれ第６図、第７図に示した。Next, Fig. 4 shows the surface roughness of the inner wall surface 22 of the matching sleeve 20 made of zirconia ceramic which has been polished to a mirror-like finish using the above-mentioned shape, and the conventional matching sleeve made of phosphor bronze has been polished to a mirror-like finish. Figure 5 shows a comparative example of the inner wall surface. In this way, the casing was set in each matching sleeve made of zirconia ceramic and phosphor copper with each surface roughness, and the optical fiber connection test was repeated under the same conditions as the ceramic ferrule was attached and detached.The results are as follows. It is shown in FIGS. 6 and 7.

定したものであった。As shown in Fig. 6, the variation in optical connection loss when using a zirconia ceramic matching sleeve is similar to that of the conventional phosphor bronze matching sleeve (Fig. 7).
The degree of variation was approximately 1/3 of that of the variation, which was extremely stable.
