Patent ID: 7555190

Claim:
An optical fiber ferrule retainer for retaining a ferrule fixed to an end part of an optical fiber in a state in which the ferrule is inserted into a ferrule insertion hole for fixing the ferrule in an axial direction of the ferrule insertion hole, the optical fiber ferrule retainer comprising: a retainer base part; and a retention member replaceably attached to the retainer base part, wherein the retention member comprises: a tubular sleeve part and a fixing part fixed to the retainer base part, the tubular sleeve part and the fixing part being formed in one piece; the ferrule insertion hole formed piercing the sleeve part and the fixing part; a split groove formed in an axial direction of the ferrule insertion hole or in a circumferential direction orthogonal to the axial direction; and a press part that is displaced so as to be able to press a peripheral surface of the ferrule inserted into the ferrule insertion hole with a partial inner face of the ferrule insertion hole defined by the split groove, wherein the retainer base part comprises an operation member that applies an external force for displacing the press part of the retention member, and wherein while the ferrule inserted into the ferrule insertion hole is retained by pressing of the press part, the fixing part can be removed from the retainer base part so as to detachably replace the retention member.
