ELECTRICAL RELAY AND RELAY, WHICH INCLUDES FERROMAGNETIC OR MAGNETIC ANCHOR THAT HAS A CONE-SHAPED AREA Russian patent published in 2017 - IPC H01H50/42 H01H51/01 H01H51/22 H01F7/08 

FIELD: electricity.

SUBSTANCE: electrical relay (2; 50; 90; 100) includes ferromagnetic frame (FF) (8) with the first (110) and opposite the second (112) land, ferromagnetic core (33), located between them, magnetic connector (16), with a first v (113) and placed on opposite second phase referred to FF, permanent magnet (12), located on the first sector of the FF, the coil (4) placed around a ferromagnetic core; and ferromagnetic or magnetic anchor (10), which includes the first phase (114), opposite the second plot (116) and swing (118), hosted with the possibility of turning to the core anchors between sites. Opposite second plot of the anchor has complementary second v-shaped area (38). In the first anchor position, the first anchor portion is attracted by the magnetic field by means of a permanent magnet, and the first and second cone-shaped portions are expanded when the coil power is turned off. In the second anchor position, the opposing second anchor portion is attracted by the magnetic field by the opposite second portion of the carcass and the first conical portion moves to the second cone-shaped portion while providing power to the coil. In this case, the magnetic connector (16) and the first airgap providing plate (20) are attached to the end (22) of the FF by two screws.

EFFECT: prevention of power losses and reduction of heating of windings.
