The purpose of this utility model is achieved through the following technical solutions: a kind of magnetron c-type magnetic assembly, including base
With two yoke assemblies, two yoke assembly symmetries are fixed on the left and right sides above base, and form c-type structure, described yoke
Assembly includes yoke, sealing cylinder, magnet steel and pole-face plate, and the lower end of described yoke is fixed on base, and the side of described magnet steel is solid
Surely having magnet steel seat, magnet steel and magnet steel seat to load in sealing cylinder, the opposite side of described magnet steel is fixed with pole-face plate, and pole-face plate covers
Covering the end at sealing cylinder, magnet steel seat is fixed on yoke, and the pole-face plate of two yoke assemblies is oppositely arranged.
Described magnet steel is bonding integral by structure glue with magnet steel seat.
Described yoke is connected by securing member A is fixing with magnet steel seat.
Circumferentially arranged on the sidewall of described sealing cylinder have multiple securing member B, securing member B to be locked on magnet steel seat.
