Abstract
The utility model relates to an on-site movable connector for an optical fiber of a loosely-shielded optical cable. The structure of the on-site movable connector comprises an outer shell 1, a pin assembly 2, a spring 3, an inner sleeve 4, a fixing member 5, a tail sleeve 6, a soft tail 7 and a loosely-shielded optical cable 8, wherein the outer shell 1 sleeves the head end of the pin assembly 2, the spring 3 is arranged between the pin assembly 2 and the inner sleeve 4, the inner sleeve is connected with one end of the tail sleeve 6 through the fixing member 5, the other end of the tail sleeve is connected with one end of the soft tail 7, and the other end of the soft tail is connected with the loosely-shielded optical cable 8. The on-site movable connector has the advantages that the optical fiber of the loosely-shielded optical cable and an inner sheath are fastened on the pin assembly, the pin assembly retracts axially when being stressed, and the optical fiber of the loosely-shielded optical cable and the inner sheath retracts along with the pin assembly when the connector is being coupled, thus the optical fiber cannot bend inside the connector, thereby avoiding optical signal loss caused by bending the optical fiber; and an outer sheath of the loosely-shielded optical cable and a reinforcer are fastened on the inner sleeve to bear the tension of the optical fiber, so as to prevent the pin assembly from being stressed directly to generate a gap with a butt-joint end surface, thereby ultimately realizing the low-loss connection of the optical fiber connector.
