OPTICAL CORD PROTECTION TUBE

PROBLEM TO BE SOLVED: To provide an optical cord protection tube which can properly prevent a communication failure caused by bending.SOLUTION: A slit 4 which can take in and take out an optical connector 102 and a cord main body 101 is formed over the whole length. An engagement part 41a is arranged at one end part of the slit 4, and an engaged part 42a which is engaged with the engagement part 41a is arranged at the other end part. The engagement part 41a and the engaged part 42a are engaged with each other in a state that the optical connector 102 is accommodated in a connector protection part 2, thereby the optical connector 102 is gripped by the connector protection part 2. A recessed annular groove 31 extending to an entire circumferential direction is continuously formed at a cord protection part 3 over a longitudinal direction, and the cord protection part 3 is not bent smaller than a prescribed bending radius.SELECTED DRAWING: Figure 1 【課題】 曲げによる通信障害を適正に防止可能な光コード用保護チューブを提供する。【解決手段】 光コネクタ１０２およびコード本体１０１を出し入れ可能なスリット４が、全長にわたって形成され、このスリット４の一端部に係合部４１ａが設けられ他端部に係合部４１ａに係合する被係合部４２ａが設けられ、コネクタ保護部２に光コネクタ１０２を収容した状態で係合部４１ａと被係合部４２ａとが係合することで、コネクタ保護部２が光コネクタ１０２を把持し、コード保護部３に、全周方向に延びる凹状の環状溝部３１が、長手方向に沿って連続的に設けられ、コード保護部３が所定の曲げ半径より小さく曲がらないようになっている。【選択図】 図１
