OPTICAL FIBER CONNECTOR

摘要

In the connection of the optical fiber wires, it is required to align each axis of two optical passages to be connected, to minimize the connection space, and to include a retaining mechanism capable of preventing any invasion of foreign materials, such as dust, vapor and water. A pair of ferrule holders 2 for retaining a pair of optical fiber wires 21 positioned opposed to each other through an adapter B are rotated simultaneously by rotating an outer ring 4 to correct the displacement of the axes of the optical fiber wires. Further, a rotating stopper portion 33 on the shaft of the ferrule holder 2 is moved in conjunction with an elastic rotating stopper plate 13 disposed at the adapter B to retain the corrected position. A silicone low crosslinking-density gel 41 having the refractive index substantially equal to that of the optical fiber wires 21 is filled in a connection space 32, to minimize the connection space 32. The function of the silicone low crosslinking-density gel 41 can cope with any variance of external environment to retain the junction of the optical fiber wires 21 and prevent any deterioration of optical transmittance. <IMAGE>
