[0002] With the development of industrial automation and informatization, the requirements for network interface cards (NICs) are becoming increasingly stringent, especially in terms of multi-port functionality, ease of installation, heat dissipation, and security. Existing industrial NICs often face challenges during installation and positioning. Traditional NIC designs require complex steps to ensure the NIC is correctly secured within the casing, which not only increases installation difficulty but also leads to positional misalignment, affecting the NIC's stability and reliability. For applications requiring frequent maintenance or replacement, the lack of a quick disassembly / replacement mechanism reduces work efficiency.
[0003] In terms of heat dissipation, prolonged operation can easily lead to overheating, which threatens the lifespan and stability of the network card and its connected devices. Security is also a crucial factor. Industrial environments present various potential risks, such as dust, moisture, and static electricity, which can damage the network card. Under complex and harsh working conditions, shock and drop resistance becomes an important indicator of a network card's adaptability. Utility Model Content
