Latest Patents: Hideki Hitachi's latest innovations include two distinct designs for electromagnetic relays. The first patent describes an electromagnetic relay of a flat configuration capable of switching electric contacts via a seesaw movement of an armature. This invention features an armature assembly with movable contacts, a coil assembly designed as a coil spool with a core, and an insulating base that supports stationary contacts, coil terminals, and connection terminals. The construction ensures that the coil assembly is affixed to the base, fully isolating the joints of the coil terminals from the contacts.
The second patent presents a miniature flat relay that consists of upper and lower insulating housing members. The lower housing snugly accommodates a coil containing a core with a centrally located permanent magnet. This magnet energizes a U-shaped magnetic structure, creating a fulcrum for seesaw mounting an elongated armature. Movable electrical contacts extend from opposite ends of the armature, while the central sections of the contacts serve as hinge points, securing the armature at its fulcrum. This design allows the armature to function in either a bi-stable or monostable configuration.
