Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic shielding, and particularly relates to a wear-resistant shielding cover. Background Art

[0002] A shielding cover is a device used in electronic equipment to prevent external electromagnetic interference (EMI) or protect internal components from the external environment. Its main functions include isolating electromagnetic interference, protecting electronic components from mechanical damage and chemical corrosion, and enhancing the reliability and performance of the equipment.

[0003] In the existing electromagnetic shielding technology, adding rubber pads is mostly used for wear resistance. However, this method causes the edges and surfaces to be easily worn during long-term use, thus shortening the service life. For example, the Chinese patent discloses "shielding cover" with the application number "CN201821555717.2". It uses nickel plating layer and tin plating layer, which not only greatly improves the wear resistance, corrosion resistance and rust prevention effect of the shielding cover, but also improves the welding convenience of the shielding cover. The small hole group and the large hole group, combined with the heat dissipation gap, contribute to further improving the heat dissipation effect of the shielding cover. However, it depends on the effectiveness of the heat dissipation holes and gaps. In practical applications, these structures may not be able to dissipate heat sufficiently, especially in high-temperature environments. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a wear-resistant shielding cover. Through the cooperation of the first heat dissipation hole, the second heat dissipation hole, the heat dissipation fins and the heat dissipation wings, the hot air inside quickly rises through the heat dissipation holes, effectively improving the heat dissipation capacity of the shielding cover, ensuring that the internal heat can be quickly exported, preventing the damage of electronic components in high-temperature environments. The combination of the anti-wear layer and the buffer layer improves the wear resistance and impact resistance of the shielding cover and extends its service life. The support layer provides good structural stability, and through the cooperation with the edge strip and the wear-resistant strip, further enhances the overall wear resistance of the shielding cover and reduces the shortening of the service life caused by edge wear.

[0005] The present utility model also provides a wear-resistant shielding cover having the above-mentioned features, including: a metal base layer, on the upper surface of the metal base layer, there is fixedly connected a heat sink, and on the lower surface of the metal base layer, there are fixedly connected an anti-wear layer, a buffer layer and a support layer; on the lower surface of the support layer, there is fixedly connected a first edge strip, on the first edge strip, there is provided a first wear-resistant strip, at the bottom of the metal base layer, there is provided a second edge strip, on the second edge strip, there is provided a second wear-resistant strip, inside the metal base layer, there are provided a first heat dissipation hole and a second heat dissipation hole, and on the upper surface of the metal base layer, there is fixedly connected a heat dissipation fin. Through the above device, through the first heat dissipation hole, the second heat dissipation hole, the heat sink and the heat dissipation fin, the heat generated inside the shielding cover is quickly exported, improving the heat dissipation efficiency. The anti-wear layer, the buffer layer and the support layer act together to enhance the wear resistance, impact resistance and the stability of the overall structure of the shielding cover.

Through the above device, through the first edge strip, the wear resistance of the edge of the shielding cover can be significantly improved, extending its service life.

[0009] For a wear-resistant shielding cover according to the present utility model, the second edge strip is located on the lower surface of the base, and the second edge strip is made of a high wear-resistant rubber material. Through the above device, through the second edge strip, the wear resistance of the bottom of the shielding cover is further enhanced, preventing the structural damage caused by the wear of the bottom.

[0010] For a wear-resistant shielding cover according to the present utility model, the first wear-resistant strips are evenly distributed on the first edge strip, and the second wear-resistant strips are evenly distributed on the second edge strip. Through the above device, through the evenly distributed wear-resistant strips, the overall wear resistance of the shielding cover is improved, ensuring its stability during long-term use.

Through the above device, the conical heat dissipation fins can quickly absorb and dissipate heat, improving the heat dissipation efficiency of the shielding cover.

[0013] Beneficial effects

A wear-resistant layer 5, a buffer layer 6 and a support layer 7 are fixedly connected to the lower surface of the metal base layer 1. The wear-resistant layer 5 resists external wear and extends the service life of the shielding cover. The buffer layer 6 provides additional buffer protection, absorbs and disperses external impact forces, and prevents damage to the internal structure.

The buffer layer 6 is fixedly connected to the lower surface of the wear-resistant layer 5, and the support layer 7 is fixedly connected to the lower surface of the buffer layer 6.

[0025] The lower surface of the support layer 7 is fixedly connected with a first edge strip 8. The first edge strip 8 increases the wear resistance of the edge and protects the shielding cover from wear. The first edge strip 8 is located around the support layer 7. The first edge strip 8 is made of a high-wear-resistant rubber material. A first wear-resistant strip 9 is arranged on the first edge strip 8. The first wear-resistant strip 9 further improves the wear resistance of the edge part and extends the service life. A second edge strip 10 is arranged at the bottom of the metal base layer 1. The second edge strip 10 improves the wear resistance of the bottom edge. The second edge strip 10 is located on the lower surface of the base 2. The second edge strip 10 is made of a high-wear-resistant rubber material. A second wear-resistant strip 11 is arranged on the second edge strip 10. The first wear-resistant strips 9 are evenly distributed on the first edge strip 8. The second wear-resistant strips 11 are evenly distributed on the second edge strip 10.

The wear-resistant layer 5 resists external wear, the buffer layer 6 absorbs impact force, the support layer 7 maintains overall stability, and the wear-resistant strips 9 and 11 on the first edge strip 8 and the second edge strip 10 enhance the edge wear resistance of the shielding cover.
