In the prior art, a transparent shielding glass door is used, which is conducive to the staff to read the data on the screen panel intuitively, and can also shield electromagnetics; the electromagnetic sealing gasket and the door frame are embedded with a structure, which can improve the sealing performance between the electromagnetic sealing gasket and the door frame, and at the same time prevent dust from entering, thereby improving the sealing effect. The receiving groove of the first silicone sheet cooperates with the electromagnetic sealing gasket extending out of the first embedded groove. When the back door is closed, the electromagnetic sealing gasket is deformed by force, filling the receiving groove and the first embedded groove, thereby improving the sealing performance between the back door and the cabinet, preventing electromagnetic leakage, and at the same time preventing external electromagnetic signals from entering the DC current screen, thereby improving the electromagnetic shielding effect.
