Embodiment
The present invention provides a kind of magnet assembly and the electromagnetic relay using the magnet assembly, for make the purpose of the present invention,
Technical scheme and effect are clearer, clear and definite, and the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should
Understand, specific embodiment described herein only to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1-2, the present invention provides a kind of magnet assembly, including two with homopolarity（S poles or N are extremely）Relative
The permanent magnet 11 that mode is set, and be connected between two permanent magnets 11 and for two opposite ends of permanent magnet 11 of shielding
The shielding slab 12 in magnetic field.When the magnet assembly is set with coil endoporus, one end that two permanent magnets are oppositely arranged is due to screen
The shielding action of block is covered, can be weakened by the active force of coil magnetic field, and one end of opposite setting is small by being influenceed, therefore
Total axial force that each magnet is subject to is not zero, and two magnet are in the same direction by axial force, realize magnet assembly in coil magnetic
The function that stress moves in.
Specifically, the material of the shielding slab 12 is iron.The material of shielding slab can also be the larger gold of other permeabilities
Category.
In order to facilitate the connection of permanent magnet 11 and shielding slab 12, the both ends of shielding slab 12 are each provided with shape and permanent magnet
11 adaptable sets of holes 121, two permanent magnets 11 are separately fixed in two sets of holes 121.Permanent magnet and shielding can so be made
The connection of block is more firm.
Specifically, the permanent magnet 11 is fixed in sets of holes 121 by being glued, welding or be threadedly coupled.
Referring to Fig. 3, the present invention provides a kind of electromagnetic relay of the magnet assembly described in use, including coil 2, it is removable
