When the military computer host is used for communication during combat, because the application environment is a field environment, some external signals in the field environment need to be shielded so as to avoid interference of the signals in the field environment on application signals in the computer host. However, when the host computer is set, in order to conveniently realize the quick connection between the main board inside the host computer and the expansion device, the whole host computer cannot be subjected to sealing treatment, so that the position of the insertion hole for installing and connecting the expansion device becomes a main leakage part of electromagnetic interference, and the safe application of the host computer in military is not facilitated.
Because shielding external electromagnetic signals relates to the safety of computer application, the honeycomb type shielding plate can shield the external electromagnetic signals, namely the electromagnetic shielding plate designed by utilizing the waveguide principle has a good electromagnetic shielding function. However, because the application is carried out in the external environment, the problem that sundries in the external environment enter the inside of the honeycomb holes and then enter the inside of the computer host easily occurs; moreover, for special application environments, such as rainy and snowy weather, it is necessary to ensure that the arrangement of the honeycomb holes does not damage the connection board and the main board inside the computer host, so the following arrangements are made here:
