Abstract
An LED display screen case includes a module, a HUB plate, a case frame, a power supply and a receiving card. One side of the HUB plate is connected with the module by a plug A and an interface A in a plugging mode. The other side of the HUB plate is connected with the receiving card by a plug B and an interface B in the plugging mode. A through hole is formed at a position corresponding to the plug B on the case frame. The plug B passes through the through hole. The receiving card and the HUB plate are connected by the plug B and the interface B in the plugging mode and fixed to the two sides of the case frame. This kind of connection type reduces the space inside the case for accommodating devices, and also ensures the good radiating effect of the case.
