Abstract: An insulated housing, in a cylindrical structure, includes an inner metal layer, an insulating layer and an outer metal coating. The insulating layer is positioned between the inner metal layer and the outer metal coating. In any end of the cylindrical structure, both a distance from the end of the inner metal layer to the end of the cylindrical structure and a distance from the end of the outer metal coating to the end of the cylindrical structure are not equal to zero, and the distance from the end of the inner metal layer to the end of the cylindrical structure is larger than the distance from an end of the outer metal coating to the end of the cylindrical structure. The inner metal layer is composed of one first metal cylinder and two second metal cylinders respectively disposed on the both ends of the first metal cylinder.
