Latest Patents
One of Nakae's latest inventions is an optical fiber cutting device. This device operates on the principle of stress rupture, allowing for stable cutting of optical fibers under predetermined conditions. It effectively eliminates damage to the blade or the cut end face, which can occur due to failure or excessive movement. The device utilizes a chuck to grip the optical fiber and applies tension through a lever mechanism, converting relative movement into precise control of the cutting blade's position.
Another significant patent is for an optical connector designed for a two-core optical fiber cord. This connector features a housing main body that holds ferrule portions fitted to the ends of paired optical fiber cores. The design includes a cord receiving portion that accommodates the covering member's end. The cord receiving portion is equipped with split members and core-guiding-path forming concave portions, which guide the optical fiber cores to separate into an almost Y-shape. This innovative design prevents the holding pieces from contacting the optical fiber cores, ensuring optimal performance.
