[0034] The setting method of the protective layer can be to perform black anodic oxidation treatment on the outer surface of the first carrier body 1, that is, to coat an oxide film on the outer surface of the first carrier body 1, which increases the corrosion resistance of the first carrier body 1 and at the same time can reduce the radiation interference of some external factors on the electronic components inside the first carrier body 1, and realizes shielding the electromagnetic interference of some external components on the shielding device 100.

[0035] There are various setting methods for the first carrier body 1, which can be a box body or a cabinet. There are also various setting methods for the second carrier body 2, such as a shell, a plate, etc. For specific setting methods, please refer to the following specific description.

[0036] The specific form of the receiving portion 21 can be a cavity, that is, opened inside the second carrier body 2.

[0037] The connection method between the first carrier body 1 and the second carrier body 2 can be fixed or movable, such as bolt connection.

[0038] In an embodiment where the second carrier body 2 is configured as a housing, the technical solution of the present utility model is provided with an opening on the second carrier body 2 for placing the electronic components into the accommodating portion 21; thus, by providing an opening on the second carrier body 2, the electronic components can be placed in the accommodating portion 21 through the setting of the opening, achieving the purpose of separating the components in the first carrier body 1 from the electronic components in the second carrier body 2.

[0039] Furthermore, the second carrier body 2 is fixed within the accommodating space 11; thus separating the first carrier body 1 from the second carrier body 2 and improving the shielding effect.

[0040] It should be noted that the opening of the second carrier body 2 is fixed to the inner wall of the first carrier body 1 to isolate the electronic components from each other.

[0041] In addition, the second carrier body 2 includes a plurality of splicing pieces 22, and a gold foil paper is provided at the connection of each of the splicing pieces 22; thus, the housing can be formed by splicing the splicing pieces 22 to carry and protect the electronic components. By providing the gold foil paper, the purpose of reducing the gap at the splicing of the splicing pieces 22 is achieved, and then the housing reaches a completely closed state, placing the electronic components in a closed space.

[0042] The connection method between the gold foil paper and the splicing of each of the splicing pieces 22 is bonding.

[0043] The splicing piece 22 can be arranged as a metal thin sheet, and the electronic components are protected by the closed space formed by the metal thin sheets.

[0044] In addition, considering the issue of convenient use, in the technical solution of the present utility model, the first carrier body 1 includes a plurality of side walls 12 on the periphery of the accommodating space 11, and a placement groove 13 is provided on at least one of the side walls 12; the shielding device 100 further includes at least one cover plate 3, the cover plate 3 is adapted to the placement groove 13, and the cover plate 3 includes the side wall 12; thus, a placement groove 13 is provided on the first carrier body 1, and through the fitting installation of the cover plate 3 and the placement groove 13, the movement between the cover plate 3 and the placement groove 13 is facilitated.

[0045] In this embodiment, the number of the placement groove 13 and the cover plate 3 is not specifically limited.

[0046] It should be explained that the fitting installation of the cover plate 3 and the placement groove 13 can be that the cover plate 3 and the placement groove 13 are in convex-concave fit. The cover plate 3 is covered on the placement groove 13, and the cover plate 3 is fixed to the first bearing body 1 by bolts.

[0047] In this embodiment, the setting method of the second bearing body 2 fixed in the accommodation space 11 can be that the cover plate 3 is fixed to the outer shell composed of each splicing piece 22. Among them, electronic components are placed in the outer shell, that is, the second bearing body 2 and the cover plate 3 can be detachably connected to the first bearing body 1 through bolts. Therefore, multiple cover plates 3 can be selected to isolate multiple electronic components.

[0048] In addition, in order to achieve a good sealing effect, a rubber strip 31 is selected to be arranged on the cover plate 3; and / or a rubber strip 31 is selected to be arranged on the placement groove 13; thus, the rubber strip 31 can be arranged on the cover plate 3; it can be arranged on the placement groove 13, or it can be arranged on both the cover plate 3 and the placement groove 13. In this embodiment, preferably, rubber strips 31 are arranged on both the cover plate 3 and the placement groove 13, which plays a role in achieving a good airtight effect.

[0049] It should be explained that there are various installation methods for the rubber strip 31, which can be bonding or clamping.

[0050] Furthermore, a conductive paint is coated on the outer peripheral wall of the rubber strip 31; thus, through the setting of the conductive paint, electromagnetic waves can be absorbed, conducted, and attenuated, thereby effectively shielding electromagnetic wave interference, and further improving the electromagnetic interference resistance of the shielding device 100.

[0051] In addition, in order to better improve the electromagnetic interference resistance of the shielding device 100, in the technical solution of the present invention, a conductive paint is coated on the outer peripheral wall of the second bearing body 2; thus, the second bearing body 2 has the function of shielding electromagnetic interference.

[0052] In addition, in order to further enhance the shielding effect, in the technical solution of the present invention, a conductive paint is coated on the contact surface where the second bearing body 2 contacts the inner wall of the first bearing body 1; thus, not only can the purpose of fixing the first bearing body 1 and the second bearing body 2 be achieved, and the space in the second bearing body 2 can be isolated from the space in the first bearing body 1, but also the electromagnetic interference resistance of the shielding device 100 can be further enhanced.
