ELECTROMAGNETIC RELAY Russian patent published in 2000 - IPC

FIELD: electrical engineering, electromagnetic relays for equipment of railway automatic and teleautomatic devices. SUBSTANCE: electromagnetic relay has yoke fabricated in the form of Z-shaped bent plate. Main panel of yoke has rectangular window drawn along longitudinal axis of panel. End shoulders bent perpendicular to panel and directed to opposite sides border main panel from opposite sides. Rod of magnetic core oriented in parallel to longitudinal axis of main panel of yoke is anchored on one of end shoulders. Two coils, each being independent winding, is put on rod magnetic core. Availability of window in main panel of yoke, its shape and dimensions make it possible to place rod of magnetic core at some distance from surface of main panel that is smaller than radius of coils. Thus each coil is partially put deeper into window and part of its side surface bulges out beyond main panel of yoke from opposite side. EFFECT: simplified structure with preservation of power, reliability and vibration stability. 1 dwg
