Abstract
The invention discloses an optical fiber connector that comprises a casing and at least one optical fiber line. The optical fiber line is imbedded in the casing by flexible sealing material. Two ends of every optical fiber line are provided with an optical fiber terminal. The optical fiber line terminal is fixedly arranged on the two ends of the casing. The connector adopts the flexible optical sealing material to fix the optical fiber line in the casing without stress, thus preventing the optical fiber line from damage caused by external heat stress and chemical stress to ensure that a product can work regularly under various severe environments such as low temperature, moist heat and mould fungus. In addition, as the optical fiber line is precisely located in the optical fiber connector and rigidly fixed by a structural member, the external stress is eliminated to ensure the reliable communication of an optical signal under vibrating and impulsive environments.
