る。2. Description of the Related Art In recent years, in the field of optical connectors, a plastic ferrule integrally formed of a resin material has been developed from the viewpoint of promoting mass production and cost reduction. A conventional plastic ferrule is configured to include a cylindrical centering portion having an optical fiber wire exposure port on a distal end surface, and a flange portion protruding radially outward at a base end of the centering portion. . The centering portion is open along the central axis to the optical fiber bare opening, and has a wire holding hole for accommodating the optical fiber wire with the coating removed, and a diameter larger than the wire holding hole. A core holding hole for accommodating the attached optical fiber core is formed so as to communicate with each other in the axial direction. The flange portion is provided integrally with the centering portion as a portion for receiving an urging force in the optical connector in the axial direction forward by the spring.

出し基準面となる。An optical connector usually includes a cylindrical positioning member called a split sleeve, and the centering portions of a pair of ferrules each having an optical fiber attached thereto are axially aligned within one split sleeve so as to be aligned with each other. By abutting the end surfaces, a pair of optical fibers can be connected concentrically. At this time, the split sleeve is pushed and expanded by the centering portion of each ferrule to exhibit elastic restoring force, and centering and supporting both ferrules at predetermined positions under the pressure. Therefore, the cylindrical outer peripheral surface of the centering portion of the ferrule serves as a centering reference surface of the optical fiber wire accommodated in the wire holding hole.

めて高い各種寸法精度が要求される。[0004] This type of plastic ferrule is integrally molded from a resin material having excellent moldability through an injection molding step and a transfer molding step, but conventionally there is no practical problem in dimensional accuracy and mechanical strength of the molded product. The challenge is how to improve it to the standard. In particular, in order to reduce as much as possible the relative eccentricity of the wire holding holes of the pair of ferrule centering portions abutted in the split sleeve during the connection operation by the optical connector, the dimensions of the centering portions of the ferrules are particularly small. It is necessary to improve the accuracy (outer diameter tolerance, cylindricity, roundness, eccentricity of the wire holding hole with respect to the outer peripheral surface, etc.). For example, in the case of an optical connector used for connecting a single mode optical fiber, a very high dimensional accuracy of the order of 1 μm is required for the centering portion of the ferrule.

And a stepped cylindrical core pin 6 that is arranged on the central axis 4 a of the third molding surface 4 and fixedly supported by the upper mold 5. The lower mold 3 and the upper mold 5 are positioned and combined with each other such that the first and second molding surfaces 1 and 2 and the third molding surface 4 cooperate with each other to define the outer shape of the plastic ferrule, Thereby, a cavity 7 is formed between the two dies 3 and 5. In the cavity 7, the first and second molding surfaces 1, 2 of the lower mold 3 define the outer shape of the centering portion and the flange portion of the plastic ferrule, and the third molding surface 4 of the upper mold 5 is located behind the flange of the plastic ferrule.

ことになる。In the conventional mold for molding a plastic ferrule, as described above, the second mold of the lower mold is used.
Since the supporting groove for positioning and holding the core pin tip portion on the molding surface is provided, the amount of eccentricity of the wire holding hole at the centering portion of the molded plastic ferrule is the core pin in the cavity, that is, the supporting groove, The position accuracy of the first molding surface with respect to the center axis is affected. For example, if the plastic ferrule is required to have extremely high dimensional accuracy with the eccentricity of the wire holding hole being 1 μm or less, the supporting groove is formed with such high positional accuracy in the second die of the lower die.
It is generally considered difficult to form on a molding surface. Moreover, the lower mold is usually used to form a support groove on the second molding surface.
As shown, the mold portion having the second molding surface is separate from the mold portion having the first molding surface. As a result, the assembly accuracy of these mold portions also affects the eccentric amount of the wire holding hole. Will have an effect.

In order to facilitate the
A small gap on the order is formed. Therefore, in the process of forming the plastic ferrule, when trying to achieve extremely high dimensional accuracy of the eccentricity of the wire holding hole of 1 μm or less as described above, a small gap of the order of μm in the support groove is required. When the tip of the core pin is slightly displaced under the flow pressure of the molten resin material, the eccentricity of the wire holding hole may be affected.

部材を採用することができる。It will be understood that the high-precision molding die 120 having the above-described configuration also provides the same operational effects as the high-precision molding die 90 described above. In particular, in this embodiment, since the spindle head 124 of the micrometer 126 is employed as the driving member 124, there is an advantage that the minute moving operation of the contact member 116 is facilitated. Note that the micrometer 126 can be attached to a simple through hole formed in the first mold 94 instead of the female screw 112 by other means such as bonding. Further, in the above-described fourth and fifth embodiments, the distal end surfaces 118a and 124a of the driving members 118 and 124 are illustrated as flat surfaces orthogonal to the axis of the driving members 118 and 124. However, the present invention is not limited thereto. A drive member having a tip surface of various other shapes such as an edge shape can be employed.
