Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic shielding devices, and in particular to a shielding cover. Background Technology

[0002] With the rapid development of modern electronic technology, the functions of portable electronic products such as mobile phones, tablet computers, and GPS navigation systems are becoming increasingly powerful. More and more electronic components are integrated on the printed circuit boards (PCBs) in these devices to meet the growing performance requirements. However, as the density of electronic components increases, the problem of electromagnetic interference (EMI) between them has become increasingly serious. Electromagnetic interference not only affects the normal operation of the components inside the device, but may also interfere with other electronic devices and even have potential effects on human health.

[0003] To solve this problem, shielding covers are widely used in electronic devices to isolate and reduce electromagnetic interference. Traditional shielding covers are usually made of metal materials. Multiple shielding cavities are formed by welding metal partitions inside a shielding frame. Each shielding cavity corresponds to an electronic component or module, thereby achieving effective shielding of each component.

[0004] However, the shielding cover in the prior art has some obvious limitations. First, although the laser welding process can achieve the connection between the metal partition and the shielding frame, the welding quality is affected by many factors, such as the location selection of the welding points, the number of welding points, the welding temperature and the welding speed. Improper control of these factors may lead to loose welding or even cold welding, affecting the overall performance and reliability of the shielding cover. Contents of utility model

[0005] The main purpose of the utility model is to provide a shielding cover with good reliability.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a shielding cover, including

[0007] Metal partition with positioning holes;

[0008] The shielding frame is provided with a positioning protrusion, the positioning protrusion includes a connected positioning portion and a crimping portion, the positioning portion is used to cooperate with the positioning hole, and the crimping portion passes through the positioning hole and is used for processing by an external pressure mechanism;

[0009] The external pressure mechanism applies pressure to the crimping portion, so that the crimping portion is deformed toward the outside thereof, and the deformed crimping portion contacts the side of the metal partition away from the shielding frame.

[0010] Furthermore, the number of the positioning holes is multiple.

[0011] Further, the number of the positioning protrusions is equal to the number of the positioning holes.

[0012] Further, the number of the positioning holes is greater than the number of the positioning protrusions.

[0013] Further, a receiving groove is further provided on a side of the metal partition away from the shielding frame, the receiving groove is communicated with the positioning hole, and the deformed crimping portion abuts against the inside of the receiving groove.

[0014] Further, a crimping slot is provided on a side of the crimping portion away from the shielding frame.

[0015] Further, a deformation groove is provided on a side wall of the crimping portion.

[0016] Further, the positioning protrusion and the shielding frame are of an integrally formed one-piece structure.

[0017] The beneficial effects of the present utility model are as follows: The shielding cover provided by the present utility model significantly improves the assembly efficiency and stability of the shielding cover by innovatively designing the connection mode between the metal partition and the shielding frame. The positioning holes on the metal partition cooperate with the positioning protrusions on the shielding frame, enabling the shielding cover to be accurately positioned to the required position without a complex adjustment process; by applying pressure to the crimping portion through an external pressure mechanism, the crimping portion deforms outward. This deformation not only realizes the tight fit between the shielding cover and the metal partition but also provides a connection method without welding. This design eliminates the risk of thermal damage that may be brought by the traditional welding process and protects the sensitive electronic components on the PCB board; the deformed crimping portion abuts against the side of the metal partition away from the shielding frame, and this abutting effect provides a mechanical locking mechanism, enhancing the overall reliability and durability of the shielding cover. Even under vibration or impact, the shielding cover can maintain the integrity of its structure, thus ensuring the normal operation of the electronic device. Description of the Drawings
