ある。[Effects of the Invention 1] As described above, the present invention includes a body and a cover formed of an insulating material, a locking piece having a locking hole provided in the cover, and a locking hole of the locking piece being inserted and locked. Since the body is provided with a locking projection that connects the body and the cover, the locking piece provided on the cover is inserted into the locking hole of the body into the locking projection, and the body and cover are connected. By joining, the conventional metal assembly frame is no longer required, reducing component costs and improving assembly workability.Furthermore, since no metal parts of the assembly frame are used externally, Even if the internal insulation performance deteriorates, there is no risk of electrical leakage or the like.
