Abstract
The invention relates to a neutral optical fiber terminal contact member and a neutral optical fiber connector. The neutral optical fiber connector comprises a plug shell, a socket shell, two neutral optical fiber terminal contact members and an external locking ring. The first neutral optical fiber terminal contact member is closely clamped and connected in the plug shell in a penetration way. The second neutral optical fiber terminal contact member is closely clamped and connected in the socket shell in the penetration way. The plug shell is connected with the socket shell in a locking way by the external locking ring so that the two neutral optical fiber terminal contact members are enabled to be in the elastic abutting connection state. The optical fiber plug cores of the optical fiber terminal contact members have a cylindrical neutral structure with no influence in rotation and installation so as to be clamped and connected by selecting reed claws or staple bolts through cooperation of transverse L-shaped slots. In plugging, the optical fiber plug cores are elastically abutted to each other and completely retracted into centering bushings of the two sides so that connection performance is stable without aligned plugging, plugging mobility is high with no division of the plug and the socket, compatibility is high, and reduction of complex production process and manufacturing and use cost is facilitated simultaneously.
