Description

Technical Field

[0001] The utility model relates to the technical field of shielding covers, in particular to a shielding cover component. Background Art

[0002] A shielding cover is a device used to limit and isolate the electromagnetic field of a circuit element or system. It is usually a frame or box made of conductive material that can completely or partially surround a circuit element or the entire system. The main function of the shielding cover is to reduce the impact of external interference on the circuit elements and improve the working reliability, performance and stability of the circuit elements.

[0003] At present, a shielding cover or a shielding frame is usually installed on the circuit board to cover the corresponding electronic components to achieve a shielding effect. However, since the electronic components generate heat during operation, if the electronic components cannot dissipate heat in time, they will be damaged due to overheating. Therefore, we propose a shielding cover assembly. Utility Model Content

By assembling the upper cover onto the lower cover, when the electronic components dissipate heat during operation, the heat dissipating fins extending into the inner side of the shielding cover and forming a Y-shaped portion absorb the heat dissipated by the electronic components, and then the heat dissipating fins extending out of the shielding cover and forming a T-shaped portion dissipate the absorbed heat outside the shielding cover, thereby ensuring normal heat dissipation inside the shielding cover and effectively shielding signals, thereby avoiding damage to the electronic components due to overheating.
