摘要:
An optical connector ferrule and a method for producing such an optical connector ferrule wherein the bonding between a metal sleeve and the main body of the ferrule. which is made of a synthetic resin material, is markedly improved. A rearward end of the metal sleeve is embedded in the synthetic resin material, preferably around a fiange of the main body. The metal sleeve may be provided with irregularities on one or both of the inner and outer surfaces thereof to further improve the adhesion between the resin of the main body and the metal sleeve.

A thermal shrinkage tube 2 is heated for shrinking onto a splice portion 1 between optical fibres 3. for example, the heating being applied first to a central portion of the tube and then successively progressing towards end portions thereof, so that the tube 2 becomes closely adhered to the splice portion 1 along the whole of its length with no trapped air bubbles. Such heating is performed by a single heating device whose heating effect varies along the length of the tube 2, such that the greatest heating density occurs at a central portion 7 of the heating device. The heating device may comprise a wire heating element wound into a helical coil or bent into a saw-tooth shape, with the pitch of the windings or saw teeth decreasing from the central portion 7 to end portions 8 and 9 of the heating device.
摘要:
An optical connector (K1) for joining exposed fiber ends (2) of coated fibers (1) and a method of manufacturing a pair of ferrules (17) for the optical connector (K1). The optical connector (K1) includes a pair of the ferrules (17) each having a flange (16), the coated fiber (1) and a metal pipe (11) molded integrally with one another by using molding resin (12), a coupling pin (10) fitted through holes (8) of the ferrules (17), a sleeve (9) for receiving the metal pipes (11) of the ferrules (17), and a housing member for axially clamping the ferrules (17) to each other.
