Latest Patents

Ichikawa holds a patent for a plastic optical fiber ferrule. This invention features an insert pipe fitted on the outer circumferential surface of the front end of a ferrule, which includes a core wire receiving bore at its axial center. A small-diameter tubular portion is insert molded coaxially with the insert pipe around the core receiving bore, adjacent to the front end. A thin-walled plastic portion is formed inside the small-diameter tubular portion. Additionally, a plastic reservoir may be included in a part of the plastic ferrule that is remote from the front end of the core wire receiving bore. This design prevents the tapering of the core wire receiving bore due to thermal shrinkage that can occur during the injection molding process.
