  • Publication number: 20230418000
    Abstract: An optical-fiber connector includes a coupling member, a core component, a sleeve member, a metal retaining member, and a pressing member. The core component is in the receiving space. The metal retaining member is connected to one of two ends of the coupling member. The elastic arm of the metal retaining member inclinedly extends toward the other end of the coupling member. Two sides of the elastic arm have a plurality of retaining structures. The sleeve member is at the other end of the coupling member and is connected to the pressing member. The pressing portion of the pressing member extends toward the elastic arm. The metal retaining member is adapted to be buckled with an adapter, so that the service life of the optical-fiber connector can be prolonged.
