Technical Field

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

Background

Electromagnetic interference (EMI) is an extremely important safety specification in the electronics industry. Many current electronic industry products, such as PCBA motherboards used in the fields of computers, servers, and vehicle-mounted devices, must comply with relevant safety standards. With the progress of science and technology, the operating frequency of each electronic component is higher and higher, and if electromagnetic interference occurs, system abnormality is caused. The chassis in the prior art is mostly made of a metal panel with a latticed opening, so as to meet the requirements of heat dissipation and EMI suppression. The chassis made of non-conductive materials also exists in the prior art, the chassis does not have an EMI (electro-magnetic interference) inhibiting effect, if the EMI inhibiting effect is required to be achieved, a conductive material needs to be coated on the non-conductive materials, the thicker the coating is, the better the EMI inhibiting effect is, and the higher the relative cost is.

Detailed Description

As shown in fig. 1, the chassis 100 includes a plurality of chassis panels 10. The plurality of chassis panels 10 enclose a housing space for housing or mounting electronic components.

Referring to fig. 2 and fig. 3, the chassis panel 10 includes a supporting plate 101 and an electromagnetic shielding layer 103. The electromagnetic shield layer 103 is attached to one side of the support plate 101.

For example, in a specific implementation, one side of the case panel facing the accommodating space in the case may be referred to as an inner side, and the other opposite side of the case panel may be referred to as an outer side. The electromagnetic shielding layer 103 may be attached to the outside of the chassis panel 10.

The support plate 101 is made of an insulating material. Further, the one side of the support plate 101 is provided with a grid-like protrusion 102.

The electromagnetic shielding layer 103 is made of a conductive material, and the electromagnetic shielding layer 103 is coated on the outer side of the grid-shaped protrusion 102.

In a specific implementation, the plurality of grids formed by the grid-shaped protrusions 102 may be irregularly-shaped grids.

For example, the conductive material of the electromagnetic shielding layer 103 is directly attached to the grid-shaped protrusions of the supporting board 101, so that the electromagnetic shielding layer 103 can form a conductive film with an irregular grid shape after being attached. The electromagnetic shielding layer 103 in this form can perform a relatively uniform shielding effect on electromagnetic radiation through a randomly disordered grid-like structure.

It is understood that in other embodiments, the plurality of grids formed by the grid-shaped protrusions 102 may also be regular grids, such as rectangular grids as shown in fig. 2, so as to facilitate the processing.

In a preferred embodiment, the support plate 101 may be made of glass. The thickness of the glass can be 0.8-6mm, and the optical transmittance of the glass can 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 formed by 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 may be a composite shielding layer formed by any several of a chromium film layer, a copper film layer, an aluminum oxide film layer, an aluminum film layer, and a silver film layer.

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

In the case panel 10 and the case 100 using the case panel 10, the supporting plate 101 is made of an insulating material, the grid-shaped protrusions 102 are arranged on one side of the supporting plate 101, the electromagnetic shielding layer 103 is made of a conductive material, the electromagnetic shielding layer 103 is coated on the outer side of the grid-shaped protrusions 102, so that the electromagnetic shielding layer 103 forms a grid-shaped structure after coating is completed, high-frequency and low-frequency electromagnetic radiation is well inhibited, the case panel 10 and the case 100 using the case panel 10 have a good electromagnetic shielding effect, the thickness of the electromagnetic shielding layer 103 can be reduced, and cost control is facilitated.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
