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.

Wall.
Compared with prior art, it is an advantage of the invention that；
1st, the fiber stub of fibre-optic terminuss contact is cylinder mesomorphism, and rotation is installed no to be affected, and is easily installed, tears open
Unload, fiber stub both fix by optional spring pawl, also optional bail coordinates horizontal l shape groove clamping, fixed in contact；Plug together
The visible fiber stub in face exposes outside front insulated mounting plate, and easily clear wiping is it is ensured that electrically connect transmission performance.
2nd, when the neutral union plugs together, the two fiber stub mutually elasticity exposing front insulated mounting plate push against and contract completely
Enter in the centring sleeve on both sides, switching performance is stable, need not be aligned and plug together, plug together that mobility is high, and no plug, socket point,
Compatibility is strong, advantageously reduces production complicated technology simultaneously and manufactures use cost.
