Description

Technical Field

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

[0002] Shielding covers can effectively shield electromagnetic fields and are usually used to reduce the electromagnetic interference of circuits from the external environment, and to suppress the electromagnetic interference generated by circuits to the external environment. Since the electromagnetic waves emitted by circuits of different specifications have different wavelengths, the ability of electromagnetic waves of different wavelengths to radiate to the external environment can be suppressed by adjusting the size of the holes through which the electromagnetic waves pass. In addition, holes at different positions have different abilities to suppress electromagnetic waves emitted by the circuit. However, most existing shielding covers adopt a one-time stamping structure. After stamping, the size and position of the holes in the shielding cover cannot be adjusted, and it cannot be compatible with circuits of different specifications, resulting in poor compatibility of the shielding cover.

[0006] Furthermore, the first shielding plate and the second shielding plate both include a horizontal section, the end of the horizontal section is integrally connected to an arc-shaped elastic section, and the end of the elastic section facing away from the plate body is integrally connected to a vertical section.

[0007] Furthermore, a latching protrusion is formed on the outer side wall of the vertical section, and a plurality of latching holes adapted to the latching protrusion are evenly distributed on the support frame.
