Abstract: A novel-structure electromagnetic relay containing a permanent magnet. At least three pairs of leading-out rods penetrate through a rectangular base, two pairs of leading-out rods are connected with the lower ends of four static spring plates respectively, an iron core and a coil framework are arranged at a diagonal position on the upper surface of the base, winding connectors of coils are connected with the other pair of leading-out rods respectively, the static spring plates are arranged at the other diagonal position on the upper surface of the base, a support is arranged at the top end of the coil framework, a pole face, a yoke and the permanent magnet are installed on the support, an armature, movable spring plates, the pole face and the yoke are located and connected through a middle shaft, and a sealing casing is covered outside the relay.

Abstract: An electromagnetic structure comprising permanent magnets comprises an outer yoke (a6), a first permanent magnet group (a3, a5), an inner yoke (a8), an armature (a1), and a second permanent magnet group (a2, a4). The outer yoke is in a hollow cylinder shape. The first permanent magnet group comprises multiple permanent magnets arrayed in a round shape, the multiple permanent magnets are connected to the outer yoke, and a magnetizing direction of each permanent magnet is along an axial direction. The inner yoke comprises an inner yoke upper base, an inner yoke sidewall, and an inner yoke lower base. The inner yoke upper base and the inner yoke lower base are separately extended outwards and horizontally from an upper end and a lower end of the inner yoke sidewall to form a circular ring. The armature comprises an armature upper base, an armature lower base, and an armature barrel body.
