Title: MAGNETIC ASSEMBLY AND ELECTROMAGNETIC RELAY USING THE MAGNETIC ASSEMBLY
Abstract:
A magnetic assembly (1), comprising two permanent magnets (11) arranged with identical poles opposite to each other, and a shielding block (12) connected between the two permanent magnets (11) and used for shielding magnetic fields of the opposite ends of the two permanent magnets (11). An electromagnetic relay using the magnetic assembly (1), comprising a coil (2), the magnetic assembly (1) movably disposed in an inner hole of the coil (2), iron sheets (3) disposed at two ends of the coil (2), a movable contact (5) fixed at one end of the magnetic assembly (1) by means of a fixing assembly (4), and a stationary contact (6) adaptive to the movable contact (5). A gap is reserved between an iron sheet (3) and a corresponding end of the magnetic assembly (1).The electromagnetic relay is able to maintain an on/off state without continuously passing a current therethrough, such that power is saved, the service life is long, and the structure is compact.
