Description

Technical Field

[0001] The utility model relates to the technical field of AC contactors, in particular to an AC contactor shell which is convenient to disassemble. Background Art

[0002] AC contactor is an electrical appliance that uses electromagnetic force and spring force to connect and disconnect contacts to control loads. The principle is that when the AC contactor coil is energized, the coil current will generate a magnetic field, which will cause the static iron core to generate electromagnetic attraction to attract the moving iron core and drive the AC contactor contacts to move. When the coil is de-energized, the moving iron core is released under the action of the release spring, causing the contacts to recover.
