  • OPTICAL CONNECTOR
    Publication number: 20170052327
    Abstract: A cover part of an optical fiber is sandwiched and pressed between a pressure welding blade and a bottom surface part. As a result of this, in a case where an external force which pulls out the optical fiber from a housing, movement of the optical fiber is suppressed by a pressing force, which makes it difficult for a ferrule to go away from a mating optical fiber. Thus, efficiency in communication with the mating optical connector can be improved.
