Vehicle-mounted integrated electromagnetic shielding case

Abstract

The utility model relates to a vehicle-mounted integrated electromagnetic shielding case, which belongs to the technical field of communication and filtering and comprises a control board card assembly, an interface board card assembly, a case panel, a case air inlet cover plate, an upper guide rail group, a lower guide rail group, a printed bottom plate, a printed bottom plate insulating pad, a printed bottom plate reinforcing plate, a debugging interface, a baffle, a coil holder, an S7 electric connector and a cooling fan. The integrated EMI power supply filtering unit effectively isolates the electromagnetic interference between the case and the outside through a power line, adopts the design of a sub-cabin section structure and a labyrinth structure, ensures the integrated electromagnetic shielding effect of the working cabin section of the case, effectively isolates the working cabin section from the heat dissipation cabin section, and facilitates the daily disassembly and maintenance of the case; the integrated electromagnetic shielding effect of the case is considered, meanwhile, a low-thermal-resistance heat dissipation path is designed, and a reasonable heat dissipation airflow channel design is matched, so that heat generated by high-power-consumption components on the board card assembly is quickly dissipated into the environment through the case body, and normal operation of an electronic system in the case is guaranteed.
