摘要： PURPOSE:To obtain an optical connector which has low connection loss with high precision by a concentric stepped projection part in the tip of the reference surface of the cylindrical body of the opticl connector. CONSTITUTION:An optical fiber end member 5 has a main cylindrical part 5B and a subordinate cylindrical part 5C while the subordinate cylindrical part 5C is provided at one end part of the main cylindrical part 5B, and the centers of both the subordinate and main cylindrical parts 5B and 5C are coincident with each other. Three spherical bodies 7 are arranged as masters in the inside of the subordinate cylindrical part 5C, and those three spherical bodies form an ampty space, into which an optical fiber wire can be inserted, around the center point of the cylindrical part 5C. In this space, the optical fiber winding is inserted and positioned and a curing material 9 is sealed from an opening part 5A and molded, thus obtaining a precise optical connector body.

摘要： PURPOSE:To effect foam molding with the quality of the products stabilized and with the rate of the foaming and the weight of the products less scattered by adjusting metering stroke of an injection plunger based upon the deviation of the foaming pressure of the melted resin cast in a cavity from the standard foaming pressure. CONSTITUTION:The pressure of the melted resin 8 at the time when foamed is detected by a pressure detector 10, and the pressure signal is inputted via a dynamic strain guage into a metering controlling apparatus 13. The original value of the metering stroke of the injection plunger 4A and standard foaming pressure (there is an allowance in the range of 15) have been previously set in the metering controlling apparatus 13, and it is compared the detected foaming pressure, and when the detected forming pressure is higher than the standard foaming pressure, the metering stroke is reset to be shortened by one unit, while when the detected foaming pressure is lower than the standard foaming pressure, the metering stroke is reset to be increased by one unit.

摘要： PURPOSE:To obtain the plug of an optical fiber connector which has superior productivity and high size precision by constituting such a mold that a cylindrical projection is formed on the end surface of the main cylinder part of the plug. CONSTITUTION:At the end part of the plug 8'A of an optical connector, i.e. a main cylinder part, an annular projection 19'A having a less outer diameter than the main cylinder part of the plug 8'A is formed by a subordinate hollow hole 19 of a mold 7. Thus, air vents, etc., which entail a decrease in external diameter out of roundness are concentrated in plug molding to realize uniform and minimum contraction of the main cylinder part of the plug in hardening, so the plug has high productivity and high size precision.

摘要： PURPOSE:To obtain an optical connector where the precision of dimensions is high and the problem of the step on end faces is solved, by using a composite where 5-30wt% ball-shaped fine particles of an inorganic filler are mixed in the polycarbonate. CONSTITUTION:5-30wt% ball-shaped fine particles of an inorganic filler are mixed in the polycarbonate. In molded goods using this composite, the contraction is uniform, and the precision of dimensions is improved. Specially, since the hardness of molded goods approaches that of optical fibers, the end face step where end faces rise is restrained to a desired value. In respect to the molding method, a movable mold 10' having a slidable movable pin 17 is brought into contact with a fixed mold 10 having a fixed pin 16, and the pin 17 is fitted to the pin 16, and said composite is charged from a runner gate 18 to form a plug. This plug is used to complete an optical connector having said advantages by the conventional method.

摘要： PURPOSE:To assemble an optical connector easily with high accuracy by using a plug formed with a hole for insertion of an optical fiber by a core pin projecting from the end face of a core forming the end face on the butt side of the plug in the stage of forming the plug. CONSTITUTION:A core pin 37 which forms a hole 8 for insertion of the strand 2 of an optical fiber 1 is erected on a core 34 forming the forward end face of a plug 6 in the stage of forming the plug 6; thereafter, said plug is formed, whereby the hole 8 is formed with high accuracy in the position matching to the plug 6. The covering at the end face of the fiber 1 is removed and a cap nut 15 and a spring 19 are inserted onto the fiber, then the fiber 1 is inserted into the holes 7, 8 of the plug 6 injected therein with an adhesive agent until the strand 2 projects from the forward end of the plug 6. The adhesive agent is allowed to set to fix the plug 6 and the fiber 1 to one body, whereafter the strand 2 projecting from the forward end face of the plug 6 is cut and the end face of the plug 6 is polished to a specular surface.
