    摘要: An interlocking fastening upper electrode assembly having an improved fastening force is proposed. The assembly is configured such that a bush inserted into a silicon electrode protrudes above the silicon electrode, and the protruding portion is inserted into and coupled to an anodizing plate so as to suppress rotation of the bush, the assembly including: an inner and outer tab composite nut coupled to an assembly groove of the silicon electrode and an anodizing plate so as to prevent rotation; an inner and outer tab nut assembled in the assembly groove of the silicon electrode and fitted to the outside of the inner and outer tab composite nut; and an assembly module coupled through the inside of a through part of the anodizing plate and assembled with the inner and outer tab composite nut in order to fix the anodizing plate provided above the silicon electrode.
