Patent ID: 7891884

Claim:
An optical receptacle comprising: a cylindrical sleeve into which a ferrule holding an end section of an optical fiber is inserted; and an optical receptacle main body in which a cylindrical sleeve holding section is formed, the cylindrical sleeve holding section holding the cylindrical sleeve by an outer circumferential surface of the cylindrical sleeve, wherein the cylindrical sleeve is formed using a material having higher elasticity than that of the optical receptacle main body, and is held within the cylindrical sleeve holding section by being press-fitted; and a sum of a press-fitted sleeve thickness (t 2 ) and a press-fitted holding section thickness (t 1 ) meets a predetermined standard dimension, the press-fitted sleeve thickness being a dimension in a radial direction from an inner circumferential surface of the cylindrical sleeve to the outer circumferential surface of the cylindrical sleeve in a sleeve press-fitted state in which the cylindrical sleeve is press-fitted into the cylindrical sleeve holding section, and the press-fitted holding section thickness being a dimension in the radial direction from an inner circumferential surface of the cylindrical sleeve holding section to an outer circumferential surface of the cylindrical sleeve holding section in the sleeve press-fitted state, and the predetermined standard dimensions satisfy: 0.836 mm≦t 1 +t 2 ≦0.849 mm wherein 0.36 mm<t 1 <0.60 mm; t 1 : press-fitted holding section thickness, and t 2 : press-fitted sleeve thickness.
