In order to shield the electromagnetic signals of the power board body 1 from the influence of surrounding electronic components, a shielding cover 5 with a shape adapted to the power board body 1 is provided. The shielding cover 5 is composed of an inner metal mesh layer 53 and a middle metal shielding plate 52. When the circuit of the external environment is affected by magnetic field interference, a shielding body can be made of a material with high magnetic permeability, that is, the metal shielding plate 52 corresponding to the shielding cover 5. High magnetic permeability is prone to saturation. A shielding body with low magnetic permeability is made by using a metal mesh, that is, the metal mesh layer 53 corresponding to the shielding cover 5, thereby shielding off part of the electromagnetic information interference. Then, the metal shielding plate 52 is used for secondary shielding.

[0026] The double-layer shielding design is adopted, the first layer attenuates the magnetic field to a proper intensity, so that the second layer is not easy to be saturated and cause shielding failure, when the shielding cover 5 shields the electromagnetic information, the metal shielding plate 52 and the metal mesh layer 53 convert the electromagnetic signal into heat, which is easy to cause the problem of overheating of the shielding cover 5, the metal shielding plate 52 is attached to the heat dissipation coating plate 51, the surface of the heat dissipation coating plate 51 is smeared with heat dissipation coating, which can dissipate the induced heat generated by the shielding cover 5 in time, so that the magnetic shielding protection effect of the power panel main body 1 is more stable, the wire inlet opening 6 is arranged on the outer side of the shielding cover 5, so as to electrically connect the shielding cover 5 with the external electrical elements.

The surface of the ground foot pad 3 is provided with a positioning hole two 10, and the surface of the ground foot pad 7 is provided with a positioning hole one 8. The heat dissipation base plate 2 is arranged between the ground foot pad 3 and the ground foot pad 7. The inner side wall of the baffle 11 is provided with a magnet, and the power panel main body 1 is fixedly connected to the shielding cover 5 through magnetic attraction.

The inner side walls of the positioning hole one 8 and the positioning hole two 10 are provided with threaded inner wires, and the power panel main body 1 and the shielding cover 5 are threadedly connected through screws.

[0028] The effect of the whole embodiment is that, in order to improve the stability of the shielding cover 5 and the power panel main body 1 in cooperation, the magnet is arranged on the inner side wall of the baffle 11, and the shielding cover 5 is installed on the surface of the power panel main body 1 more stably by using the magnetic attraction effect; at the same time, the ground foot pad 7 at the four corners of the shielding cover 5 and the ground foot pad 3 at the four corners of the power panel main body 1 can be positioned, and the positioning hole two 10 with a threaded hole is arranged on the ground foot pad 3, and the positioning hole one 8 with a threaded hole is arranged on the ground foot pad 7, so as to be fixedly connected twice.
