<p>METHOD FOR PRODUCTION OF OPTICAL FIBER CONNECTORS Disclosed are methods for production of plastic optical fiber connectors specifically for production of plastic plug ferrules employable for plastic optical fiber connectors, wherein improvements are realized to decrease the production cost thereof, to enable accurate finished dimension therefor, to enhance the advantage of mass production therefor, and to decrease the connection loss thereof. The method comprises (1) a step to produce a round hole at the center of one end of a rod, the round hole having a diameter approximately identical to that of a bare fiber of optical fibers to be connected with each other, (2) a step to insert a pin to the round hole to produce a master mold, (3) a step to employ an electroform process such as a nickel plating process to plate a metal layer to a predetermined thickness on the external surface of the master mold for the purpose to produce an electroformed mass, (4) a step to draw the master mold from the electroformed mass, remaining the pin alone in the electroformed mass, for` the purpose to produce an electroformed mold, (5) a step to produce a metal mold by assembling the electroformed mold, a pipe and a pair of upper and lower metal dies, and (6) a step to fill a molten resin or plastic into the cavity of the metal mold for the ultimate purpose to produce a plastic plug ferrule to be assembled in a plug employable for a plastic optical fiber connector.</p> |
