Description

Chassis panel and chassis using the same

technical field

The invention relates to a case panel and a case using the case panel.

Background technique

Electromagnetic interference (EMI) is an extremely important safety specification in the electronics industry. Current electronic industry products, such as PCBA motherboards used in computers, servers, automotive equipment and other fields, must comply with relevant safety regulations. With the advancement of science and technology, the working frequency of various electronic components is getting higher and higher, and if electromagnetic interference occurs, it will lead to system abnormalities. Most of the chassis in the prior art are made of metal panels with grid-like openings to meet the requirements of heat dissipation and EMI suppression. There are also cases made of non-conductive materials in the prior art. Such cases do not have the effect of suppressing EMI. To achieve the effect of suppressing EMI, a conductive material needs to be coated on the non-conductive material, and the thicker the coating, the better the effect of suppressing EMI. The better, the higher the relative cost.

Detailed ways

As shown in FIG. 1 , the chassis 100 includes a plurality of chassis panels 10 . The plurality of chassis panels 10 are enclosed to form an accommodation space for accommodating or installing electronic components.

Referring to FIG. 2 and FIG. 3 at the same time, the chassis panel 10 includes a support plate 101 and an electromagnetic shielding layer 103 . The electromagnetic shielding layer 103 is attached to one side of the support plate 101 .

For example, in a specific implementation, the side of the chassis panel facing the accommodating space in the chassis may be designated as the inside, and the other opposite side of the chassis panel may be designated as the outside. The electromagnetic shielding layer 103 can be attached to the outside of the chassis panel 10 .

The support plate 101 is made of insulating material. In addition, the side of the support plate 101 is provided with grid-like protrusions 102 .

The electromagnetic shielding layer 103 is made of conductive material, and the electromagnetic shielding layer 103 is coated on the outside of the grid-shaped protrusions 102 .

In a specific implementation, the grids formed by the grid-like protrusions 102 may be grids with irregular shapes.

For example, the conductive material of the electromagnetic shielding layer 103 is directly attached to the grid-like protrusions of the support plate 101 , so that after the electromagnetic shielding layer 103 is attached, a conductive film with an irregular grid shape can be formed. The electromagnetic shielding layer 103 of this form can play a relatively uniform shielding effect on electromagnetic radiation through the random disordered grid structure.

It can be understood that, in other embodiments, the grids formed by the grid-like protrusions 102 can also be grids with regular shapes, such as rectangular grids as shown in FIG. 2 , so as to facilitate processing and forming.

In a preferred embodiment, the support plate 101 may be made of glass. The thickness of the glass may be 0.8-6mm, and the optical transmittance of the glass may be 86%-92%.

In another preferred embodiment, the electromagnetic shielding layer 103 may include one or more of a chromium film layer, a copper film layer, an aluminum oxide film layer, an aluminum film layer, and a silver film layer. That is, the electromagnetic shielding layer 103 may be a single-layer shielding layer composed of one of a chromium film layer, a copper film layer, an aluminum oxide film layer, an aluminum film layer, and a silver film layer, or a chromium film layer, a copper film layer, and a single-layer shielding layer. A composite shielding layer composed of any of several layers, aluminum oxide film layer, aluminum film layer, and silver film layer.

In a specific implementation, the thickness of the electromagnetic shielding layer 103 can be set to 50-800 nm according to specific requirements.

In the above case panel 10 and the case 100 using the case panel 10 , the support plate 101 is made of insulating material and the side of the support plate 101 is provided with grid-like protrusions 102 , and the electromagnetic shielding layer 103 The electromagnetic shielding layer 103 is made of conductive material and the electromagnetic shielding layer 103 is coated on the outside of the grid-like protrusions 102, so that the electromagnetic shielding layer 103 forms a grid-like structure after the coating is completed. It has better suppression ability, so that the chassis panel 10 and the chassis 100 using the chassis panel 10 have a good electromagnetic shielding effect, and at the same time, the thickness of the electromagnetic shielding layer 103 can be reduced, which is beneficial to control the cost.
