    • An optical connector having an optical fiber inserted into a connector main body includes a buckling regulating section whose length in an optical fiber insertion direction is formed variable and which regulates a buckling of the optical fiber while becoming short in an optical fiber insertion direction when the optical fiber is inserted into the connector main body. Even if an insertion area is made long, since no buckling of the optical fiber is generated, the buckling regulating section can sufficiently increase an insertion force of the optical fiber. Thus, even when foreign substances such as dusts enter and an insertion resistance increases, the optical fiber can be securely inserted. Further, the buckling regulating section is very advantageous to realize an end surface preparation of the optical fiber making use of the insertion force of the optical fiber such as a coating removing of the optical fiber, and an end surface grinding preparation of the optical fiber.
    • 具有插入到连接器主体中的光纤的光连接器包括:在光纤插入方向上的长度形成为可变的并且在光纤插入方向变短时调节光纤的翘曲的屈曲调节部, 光纤插入连接器主体。 即使插入区域长,由于不会产生光纤弯曲,因此翘曲调节部能够充分地增加光纤的插入力。 因此,即使当灰尘等异物进入并且插入阻力增加时,也可以牢固地插入光纤。 此外,弯曲调节部非常有利于利用光纤的插入力来实现光纤的端面准备,例如光纤的涂层去除以及光纤的端面研磨准备。
