Abstract

PURPOSE:To simplify the structure and to maintain high connection performance which is stable for a long period by forming both a sleeve and a core of zirconia ceramic. CONSTITUTION:The connector consists of a 1st plug P1, a 2nd plug P2, and the sleeve S. The main body 3 of the 1st plug P1 is formed of synthetic resin by casting outside a zirconia-made ceramic core 2. wherein a through hole 2a into which an optical fiber is inserted is bored, so that almost half of the ceramic core 2 projects. A through hole 3a into which the fiber is inserted is bored in the main body 3, which is equipped with a screw ring 4 having a flange 4a at one end so that a step part 3b is engaged and also having a screw groove 4b formed at the inner peripheral part on the other end part. A 2nd plug P2 has the same constitution with the 1st plug P1. The main body of the sleeve S has a screw groove 6 made of synthetic resin outside the zirconia-made ceramic sleeve 5 containing the ceramic cores 2 and 7.

2. Description of the Related Art As shown in FIG. 3, a conventional optical fiber connector (hereinafter simply referred to as a "connector") has a structure in which a fiber F1 and a fiber F2 are connected to each other with their tips completely aligned with each other. It is necessary to reduce the difference between the outer diameters of F1 and F2 and the diameters of the pores H formed in the cores N1 and N2 made of metal or ceramic into which the fibers F1 and F2 are inserted, and this core is also required. N1,
After making the center of the pore H opened in N2 and the center of the outer diameter of the cores N1, N2 coincident with each other, two fibers F are simultaneously formed.
In order to match the centers of 1 and F2 to the sleeve B,
The cores N1 and N2 are inserted in a state in which the cores N1 and N2 are in a highly precise positional relationship and the tip end surfaces of the cores N1 and N2 are in close contact with each other with a proper pressure by the spring D, and are fixed to connect the fibers F1 and F2. Connector is used.

The conventional sleeve B is mainly made of a copper alloy such as phosphor bronze, and the cores N1 and N2 are mainly made of alumina ceramic or stainless steel. In connecting optical fibers to each other with such a connector, the deviation between the fibers F1 and F2 is set to about ± 1 μm or less in order to minimize the optical connection loss, and the fibers F1 and F2 are
In order to reduce the deviation of the end face angle of 2 from 0.5 degrees or less, the inner wall surface of the sleeve B is required to have extremely high accuracy in terms of surface roughness, straightness, and roundness.

As described above, according to the present invention, in the optical fiber connector having a structure in which the core having the optical fiber mounted in the pore on the central axis is inserted into the sleeve, the sleeve and the core are formed of zirconia ceramic. , The inner diameter tolerance of the pores into which the fibers are inserted and the coaxiality of the inner and outer diameters can be machined with high precision, and in the case of ceramics, since it is a polycrystal, the wall surface of the pores has minute protrusions. Since it is composed of (crystal), the friction surface with the fiber is small, and therefore the fiber can be easily inserted into the pores.

Although zirconia ceramic has a high hardness, its Young's modulus is 1 as compared with alumina ceramic.
It has moderate elasticity at about / 3. Therefore, when the core is fitted into the sleeve integrally formed of zirconia ceramic, the sleeve does not crack due to the appropriate elasticity. Moreover, since the hardness is higher than that of the metal such as phosphor bronze used for the conventional sleeve, the inner wall surface of the sleeve is less likely to be scratched or worn by the insertion of the core, and the holding force is not reduced due to deformation or the like. Therefore, this optical fiber connector can maintain stable and high connection performance for a long period of time.

Further, if the core is integrally formed of zirconia ceramic, the tip surfaces of the pair of cores fitted in the sleeve are elastically deformed by the appropriate elasticity of the zirconia ceramic, and the cores are easily adhered to each other. Connections can be made without interposing an air layer between the optical fibers mounted on the central axis of the child.

Therefore, in the optical fiber connector in which the sleeve and the core are integrally formed of zirconia ceramic, the tip surfaces of the cores coincide with each other in the center axis in the sleeve which is processed with high accuracy and is free from wear and deformation for a long period of time. Since they are brought into close contact with each other in a state in which they are brought into contact with each other, it is possible to maintain extremely high connection performance for a long period of time with less end face reflection and less connection loss.
