Latest Patents
One of his latest patents is the L-type coaxial connector. This invention features a housing that includes a cylinder portion, a back portion, crimping portions, and supporting portions. The cylinder portion has a first opening, a second opening, and a cut, allowing it to contact an external conductor of a receptacle inserted from the first opening. The back unit effectively covers the second opening, while each supporting portion is strategically placed on the cylinder portion. The crimping portions extend from the back portion and are bent to face the back portion, ensuring that the supporting portion is positioned between the crimping portion and the back portion. An elastic portion is also integrated between the crimping portion and the supporting portion.
Another notable patent is a coaxial connector designed with locking projections. This connector can be press-fitted and detached from a receptacle groove multiple times with reduced load, thereby extending its lifespan without increasing the height of the connector. The tubular portion of the housing is rounded, featuring a gap formed by the opposite ends of the tubular portion. A first locking projection is positioned diametrically opposite the gap, while the second and third locking projections are spaced approximately 90° or more from the first projection in a circumferential direction. The circumferential length of each projection is intentionally set smaller than the length of the interval between the first locking projection and the second or third locking projection.
