The invention relates to an optical cable connector for an environment resistant neutral optical cable, mainly comprising a lock sleeve, a belt locating pin, a locating hole, a plug body for a first and a second optical fiber locating holes, a protective bobbin and two ceramic ferrules; the two ceramic ferrules are positioned in the first and the second optical fiber locating holes through a small pressure spring and a pressure spring sleeve; and the front end of any ceramic ferrule is provided with an optical fiber butt joint assembly. When the connectors of the invention are connected in pairs, the locating pin of a connector matches with the top position of the locating hole of the other connector, and the ceramic ferrule of one connector is connected with the ceramic ferrule of the other connector through the optical fiber butt joint assembly. The optical cable connector has the advantages of stability and firmness for splicing, precise for positioning, small signal attenuation, stable transmission, compact structure, convenience for mounting, dismounting and maintenance, resistance to environmental change, and long service life, thereby satisfying the commercial or military requirement of miniaturization, high performance and field use.
