[0002] A wireless module is a functional module that integrates chips, memory, power amplifier devices, etc. on a circuit board and provides a standard interface. Various terminals can use wireless modules to achieve communication or positioning functions. As a product with integrated communication functions, wireless communication modules are widely used in smart devices. For example, in smart cars or electric cars, cellular wireless communication modules are an essential component that enables cars to access cellular wireless networks in order to provide car owners with a variety of functions.

[0003] In order to prevent electromagnetic interference and electromagnetic radiation, a shielding cover is usually designed to perform electromagnetic shielding on the wireless communication module, so as to achieve the effect of reducing interference. However, the effect of increasing the anti-interference ability only by adding a shielding cover is poor. The shielding cover often includes a shielding frame and a shielding cover. The side of the shielding cover in the prior art is continuous. When the shielding cover and the shielding frame are assembled, the shielding cover applies a gripping force to the shielding frame from all sides. The gripping force will be transmitted to the circuit board of the wireless communication module through the shielding frame, thereby affecting the flatness of the circuit board of the wireless communication module, affecting the flatness of the circuit board of the wireless module. For this reason, a wireless module with high anti-interference ability is proposed. Utility Model Content

[0004] In view of this, the utility model provides a wireless module with high anti-interference capability to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0014] Further preferably, three mounting holes are provided on the upper surface of the PCB substrate.

[0015] Since the embodiment of the utility model adopts the above technical scheme, it has the following advantages: the utility model inserts the limit plug into the slot and presses the shielding cover, so that the elastic sheet produces elastic deformation. At this time, the limit plug is pulled, and the limit plug drives the bending part to bend. When the shielding cover is released, the elastic sheet is reset and pushes the shielding ring upward.
