Description

Technical Field

[0001] This utility model relates to the field of shielding technology, and in particular to a novel 5G shielding cover with a stretching notch. Background Technology

[0002] Shielding devices are present in communication and other terminal products that require shielding functions. These devices are mounted on the PCB board of electronic modules to provide shielding. Applications of shielding covers: Used in conjunction with PCB circuit boards, set-top boxes, mobile phones, telecommunications equipment, etc. Function of shielding covers: Primarily, they block electromagnetic waves from entering the circuit, protecting it from harmful electromagnetic radiation. Shielding covers are tools used to shield electronic signals; their function is to shield external electromagnetic waves from affecting internal circuits and to prevent internally generated electromagnetic waves from radiating outwards.

[0003] With the advent of 5G, there is a greater demand for higher-frequency data transmission. Therefore, numerous notched shielding covers are used to facilitate data transmission on PCBs. Traditionally, data transmission on PCBs involves creating notches in the shielding cover to allow the copper busbars on the PCB to pass through. The shielding cover provides the shielding effect, while the copper busbars on the PCB serve the data transmission function.

[0004] The traditional purpose of shielding notches is to allow unused copper busbars to pass through, facilitating rapid data transmission. However, due to limitations in mold manufacturing processes and cost, the tolerance of these notches is typically around ±0.15 mm. If the notch height (0.3 mm) is unstable, or if the notch shape is inconsistent, failing to meet the required data dimensions and tolerances, it can easily damage the data output copper busbars on the PCB board, leading to defective or substandard products, and severely impacting the quality and delivery of the assembled PCB. Therefore, stabilizing and ensuring the notch dimensions is extremely important.

[0005] With the rapid development of the 5G era, the higher the precision of the notch size, the better, as this can better protect the copper busbars on the PCB board and enable faster and more stable data transmission. This demand for higher notch precision increases manufacturing costs, and the number of copper busbar output lines on the PCB board also increases, correspondingly requiring higher precision in the shielding notch. However, the actual need is for more stable shielding notch precision while reducing manufacturing costs. Utility Model Content

[0006] The purpose of this invention is to overcome the defects of the existing technology and provide a new type of 5G shielding cover with a stretch notch, which improves the production efficiency of PCB boards, enhances the stability and reliability of PCB boards, and completely solves the problem of the copper busbars of the PCB board being damaged by the notch in the shielding cover. It also reduces the cost of manufacturing parts, improves the quality of parts, reduces risks, and reduces the cost of mold manufacturing.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] Reduce manufacturing costs, minimize damage to PCB copper busbar output lines, improve manufacturing technology, and better provide high-quality supporting components for 5G services.

[0009] The original shielding notch was obtained by first punching and then stretching the shielding. This resulted in inconsistent notch size and shape with large tolerances. When the notch height was too small, it became irregular due to stretching, easily damaging or destroying the transmission copper traces on the PCB, causing device instability or breakage. The stretched shielding overcomes both the instability of the notch size and shape.

[0010] This utility model provides a novel 5G shielding cover with a stretch notch. The shielding cover has a box-shaped or cover-shaped structure, with a top plane, four sides and a bottom edge. The sides of the shielding cover are provided with stretch notches. The shape and size of the stretch notches are determined according to their functional requirements and installation layout in 5G equipment.

[0011] Furthermore, the stretch notch is polygonal.

[0012] Furthermore, the stretching notch is trapezoidal.

[0013] Furthermore, the edges of the stretch notch are smooth and continuous, and it is formed in one step through a stretching process.

[0014] Furthermore, the depth of the stretch notch is designed based on the overall thickness of the shield.

[0015] Furthermore, during the stretching process, the metal material undergoes plastic deformation around the stretching notch, forming a naturally transitioning curved or inclined surface that connects the main body of the shield to the stretching notch, making the entire structure more stable in terms of mechanical properties.

[0016] Furthermore, the shielding cover is a copper alloy or stainless steel shielding cover.

[0017] Furthermore, the thickness of the shield is between 0.1 and 0.5 mm.

[0018] Furthermore, the surface of the shielding cover is electroplated and painted.

[0019] Furthermore, the shielding cover is fixed to the housing by rivets.

[0020] The innovative stretched-notch shield fundamentally eliminates the possibility of damage to the PCB copper busbars. It ensures the stability of assembled and soldered components without damaging the copper busbars on the PCB, guaranteeing stable data and signal transmission through the PCB copper busbars. The stretched-notch shield, a significant improvement over the original notched shield, offers greater stability and is more competitive in PCB data transmission than shields with punched notches.

[0021] A 5G shield with stretch notches must have two special functions: First, it must be a shield, possessing all the functions and features of an equivalent shield. Second, the shield must have one or more stretch notches, with their corresponding positions and sizes selected based on the data transmission requirements and dimensions of the PCB board. Third, the shield with stretch notches must not damage the copper busbars transmitting data on the PCB board. Fourth, the copper busbars, to accommodate the stretch notches, are manufactured using a stretching process instead of a punching process.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] This reduces manufacturing costs, minimizes damage to PCB copper busbar output lines, improves manufacturing technology, and provides better high-quality components for 5G services. It ensures the stability of 5G communication components from damage caused by chips, significantly improves the quality of 5G communication components, increases production efficiency, and plays a direct role in enhancing the industry's quality and stability in 5G terminals.
