The utility model relates to an in the flexible shielding case of liquid metal's vaulting pole formula, including upper and lower flexible insulation layer, be located the conducting coating between the upper and lower flexible insulation layer, with conducting coating electrical connection's earth conductor and being located the vaulting pole at shielding case edge, the shielding case rim seal is equipped with and is suitable for the vaulting pole freely to take out the cavity of inserting. Compare in traditional shielding case, shielding case can fold, and characteristics such as portable and use, technology are also comparatively simple.
