In FIG. 1, the optical connector axial alignment structure of the present invention includes a ferrule, an optical fiber, a frame, a coil spring, a coupling nut, an adapter, a ring, and the like as in FIG. It is characterized by the improvement of. Therefore, except for the frame and the ring, it is the same as that in FIG. 3, and therefore only the drawing of the frame 9 and the ring 10 will be described here.

内部凸部102を形成した構成である。The frame 9 which characterizes the present invention is made of metal such as stainless steel, and has a flange 91, a groove 92, an internal protrusion 93, and a plurality of recesses 94 formed at equal intervals on the circumference. The ring 10 fitted in the frame 9 is made of metal such as stainless steel, and has a positioning projection 101 on the outer circumference and an inner projection 102 corresponding to a plurality of recesses 94 on the inner circumference at equal intervals on the circumference of the frame 9. It is the formed structure.

構成としたものである。When the ring 10 thus configured is inserted into the frame 9 in the direction of the arrow, the plurality of internal convex portions 102 of the ring 10 are first fitted into the grooves 92 of the frame 9. Here, when the adapter 7 (not shown) is inserted into the frame 9, the positioning projection 101 formed on the outer periphery of the ring 10 and the positioning notch 72 of the adapter 7 are fitted to each other, and the adapter 7 can freely rotate with respect to the frame 9. Therefore, after aligning the eccentric direction of the fiber to an appropriate position and pushing the adapter 7 in the axial direction,
The internal convex portion 102 of the ring 10 meshes with the concave portion 94 of the frame 9.

ダプタにより固定）に対し、同一方向（または１８０°
反対方向）にすれば第２図(b)の如くなる。As shown in Fig. 2 (b), when the ferrules 1 are in the same direction, the combination of eccentricity of ε 1 and ε 2 is eccentricity when ε 1 −ε 2 strikes, but Fig. 2 (c) As described above, in the case of eccentricity in the opposite direction to (b), ε 1 + ε 2 increases. (Actually, it is two-dimensional including the 360 ° direction, and three-dimensional when the angle deviation is included.) Therefore, the eccentric direction is the same direction (or 180 °) with respect to the positioning projection of the connector plug (fixed by the adapter).
If the direction is opposite, the result will be as shown in Fig. 2 (b).

通常、組立て時にその方向を測定することは困難であ
