[0002] Shielding devices are present in terminal products such as communication devices that require shielding functions. Shielding covers are tools used to shield electronic signals. Shielding covers are mainly used in mobile phones, GPS and other fields. They are designed to prevent electromagnetic interference (EMI) and to shield components and LCMs on PCBs.

[0003] The shielding cover is used in conjunction with PCB circuit boards, set-top boxes, mobile phones, telecommunications equipment, etc. Its function is primarily to block electromagnetic waves, protecting them from harmful electromagnetic radiation. Its purpose is to shield external electromagnetic waves from their influence on internal circuitry and to prevent harmful electromagnetic radiation emanating from within the device.

[0004] Due to the rapid development of 5G technology, there is a need for more efficient blocking of harmful electromagnetic waves. This requires using multiple enclosed, bent edges on the same product to shield the influence of external electromagnetic waves on internal circuits, while also shielding the outward radiation of internally generated electromagnetic waves. However, as... Figures 1-2 As shown, the existing shielding cover is made by first punching and then bending the shielding cover. There will be fold seams between the bends, which makes it difficult to achieve a sealing effect and has a certain impact on shielding electronic signals. Summary of the Invention

[0005] The purpose of this invention is to overcome the defect of existing shielding covers having fold seams between bends, making it difficult to achieve a sealing effect, and to provide a shielding cover with a circumferential edge.

[0008] The edging portion includes an edging provided on the lower part of one side of the first side, and the edging is bent and closely attached to the outer side wall of one side of the second side.

[0009] In some specific embodiments, a clearance area is provided on the lower part of one side of the second side, and the edging is bent beyond the clearance area so that the edging is in close contact with the outer wall of the second side.

[0010] In some specific embodiments, the width of the edging is greater than the width of the avoidance area.

[0011] In some specific embodiments, the top of the edging is flush with the top of the clearance area.

[0012] In some specific embodiments, the thickness of the edging is the same as the thickness of the first side edge.

[0013] In some specific embodiments, the top projection of the cover is an irregular polygon.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0033] Example 1:

[0034] like Figures 3-4 As shown, a shield with a circumferential edging is provided, including a shield body 1. The shield body 1 is provided with a plurality of side portions, including a first side portion 2 and a second side portion 3. The first side portion 2 and the second side portion 3 are closely fitted together and connected by the edging portion.

[0035] The edging portion includes an edging 4 located on the lower part of one side of the first side 2, and the edging 4 is bent and closely attached to the outer side wall of one side of the second side 3.

[0036] In this technical solution, by designing a lining 4 on the first side 2, the lining 4 is bent and tightly adheres to the outer wall of one side of the second side 3, effectively sealing the fold seam between adjacent sides and overcoming the difficulties in sealing and the interference of electromagnetic waves on internal equipment. The cover 1 is also a closed structure that can completely cover or enclose important functional components such as relays, chips, microcontrollers, and circuit boards that need protection, ensuring that electromagnetic waves cannot bypass the shielding cover and enter the protected area. This effectively prevents the radiation interference generated by the wireless module from spreading outwards and also prevents external interference sources from interfering with the normal operation of the wireless module. This fundamentally solves the problems of electromagnetic wave radiation and interference, thereby ensuring the normal operation and stability of the internal equipment.

[0037] More specifically, a clearance area 5 is provided on the lower part of one side of the second side 3, and the edging 4 is bent beyond the clearance area 5, so that the edging 4 is in close contact with the outer wall of the second side 3.

[0038] The width of the edging 4 is greater than the width of the avoidance area 5.

[0039] The top of the edging 4 is flush with the top of the clearance area 5.

[0040] The thickness of the edging 4 is the same as the thickness of the first side 2.

[0041] The top projection of the cover 1 is an irregular polygon. Examples include quadrilaterals, pentagons, and hexagons.

[0042] The cover 1 has several cutouts for copper busbar output lines that transmit data on a PCB board to pass through.

[0043] The shielding cover is formed by stamping.

[0044] The shielding cover is a metal or conductive polymer shielding cover. For example, the shielding cover is an aluminum or copper shielding cover. This material can absorb or reflect electromagnetic waves, thereby reducing or eliminating interference with internal equipment. When electromagnetic waves pass through the shielding cover, the shielding cover produces a shielding effect; for example, a metal shielding cover can reflect electromagnetic waves on its surface, preventing them from penetrating into the internal area, acting like a wall blocking electromagnetic waves.

[0045] The surface of the shielding cover is electroplated and painted.

[0046] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
