The metallic shell encloses four sides of the insulated housing and includes a top cover plate, a rear cover plate, and pins. The top cover plate is located atop the base portion. The rear cover plate is extending downwardly to the rear side of the base portion from the rear side of the top cover plate. The rear cover plate includes a bottom surface and a bent sheet substantially perpendicular to an outer wall of the rear cover plate and extended outward from the outer wall of the rear cover plate, and the pins are extending downwardly from the bottom surface.
