Technical Field
[0001] This utility model relates to the field of computer technology, and in particular to a WiFi module assembly structure. Background Technology
[0002] Based on the demand for network access in modern life and work, existing communication equipment and computers have integrated WIFI modules to achieve wireless network connectivity.
[0003] WiFi modules can be secured to the device's motherboard using methods such as soldering, connectors, threaded fasteners, clips, or adhesives. Soldering includes surface mount technology (SMT) and through-hole soldering. SMT enables smaller packages and higher connection reliability, and is widely used in various miniaturized electronic devices. Through-hole soldering offers higher connection strength and is suitable for devices with high stability requirements. Connector mounting uses specially designed connectors to connect the WiFi module to the motherboard. This method is advantageous because it facilitates installation and removal, and is commonly used in devices that require frequent module replacement or maintenance. Threaded fasteners or clips are suitable for larger WiFi modules or situations requiring stronger mechanical fixation. Threaded fasteners offer a more robust fixation and can withstand certain external impacts. Clips are relatively easy to install and remove, but their fixation strength is inferior to threaded fasteners. Adhesive bonding saves assembly space and is suitable for ultra-thin devices, but its reliability is insufficient.
[0004] In existing technologies, portable computer WiFi modules are mostly secured with threaded fasteners. This ensures the WiFi module remains secure during prolonged use, guaranteeing its normal operation and balancing replaceability and stability. However, assembly structures using threaded fasteners typically require additional slots or brackets to secure and protect the WiFi module, necessitating significant space allocation. As technology advances and user demands increase, users are placing higher requirements on the user experience and aesthetics of portable computers. Consequently, portable computer designs are increasingly leaning towards thinner and lighter designs. To save on WiFi module height, ultra-thin portable computers tend to use adhesives or complex snap-fit structures for securing the WiFi module; however, these methods are complex and lack sufficient reliability. Summary of the Invention

[0007] The thickness of the tablet body is 0.2±0.05mm.
[0008] The adhesive backing layer is a thermally conductive double-sided adhesive layer coated on the contact surface between the tablet body and the WiFi module.
[0009] The thickness of the adhesive backing layer is 0.05~0.1mm.
[0010] The edge of the pressing body extending from one end of the WiFi module extends toward the motherboard and then bends toward the WiFi module to form the mounting part; the mounting part is provided with screw holes, and the pressing body is provided with a first through hole corresponding to the screw holes of the mounting part; the threaded fastener is located between the pressing body and the motherboard after being tightened.

The screw passes through the first through hole and the screw hole and is locked in the threaded hole of the copper stud, thereby fixing the pressure plate to the main board. After the screw is locked, the head of the screw passes through the first through hole and abuts against the mounting part, so that the screw is located between the pressure plate body and the main board.
[0012] The pressure plate also includes a positioning hook extending from the edge of the pressure plate body along the WiFi module toward the motherboard. During assembly, the positioning hook abuts against the side of the WiFi module to achieve positioning.

In addition, the adhesive layer between the clamping plate and the WiFi module of this utility model not only serves to pre-fix the clamping plate, but also provides auxiliary heat dissipation, preventing the material aging of the WiFi module and clamping plate due to temperature rise during long-term use, which would lead to signal attenuation, further improving the signal stability of the WiFi module. The WiFi module assembly structure of this utility model can take into account the requirements of WiFi module strength, signal optimization, and thinness, and is especially suitable for ultra-thin portable computer devices or portable communication devices, with good application prospects.
