GIS terminal box and GIS terminal box subassembly

The utility model relates to a GIS terminal box and GIS terminal box subassembly which set up be used for by direct the GIS casing wear the corbel back slab on fix the casing at GIS, it is including the frame component that has the bottom plate. Interior intracavity being surrounded by the frame component is provided with the terminal chamber, and wherein, the bottom plate has the through -hole of arranging at the center and is arranged in wearing to guide to the terminal chamber from wearing the cable that the corbel back slab stretches out. The terminal chamber is limited at its side of surrounding department operation protectorate, and the terminal strip restriction in the inner chamber is arranged at least in part in at least one side wherein, wherein, relatively arranges the apron that can fix with the bottom plate with unclamping, operates the protectorate orientation through the apron and limits the terminal chamber outward. The invention is created and is also related to a GIS terminal box subassembly that has the GIS terminal box of creation according to the invention.
