 1, the network cabinet components: network cabinet framework and cover (door), and generally has a rectangular shape, landing placed. The normal working of the electronic equipment to adapt to the environment and security. This is second only to the system level of an assembly. Do not have the closed structure of the cabinet known as the rack. 2, network cabinets, quality requirements: network cabinet should have good technical performance. The structure of the cabinet should be based on the equipment's electrical, mechanical, performance and use of environmental requirements, the necessary physical and chemical design to ensure that the structure of the cabinet has good stiffness and strength, and good electromagnetic isolation, grounding, noise isolation, ventilation and other properties. In addition, network cabinets should have anti-vibration, shock, corrosion, dust, water, radiation and other performance, in order to ensure that equipment is stable and reliable work. The network cabinet should have good usability and security facilities, ease of operation, installation and maintenance, and to ensure the safety of the operator. The network cabinet should be easy to manufacture, assemble, debug, and packing and shipping. The network cabinet should be in line with the requirements of the standardized, normalized, serialized. Cabinet shape and beautiful, for color coordination. 3, network cabinets, production and development: network cabinet early casting or angle by screws, rivets, connections or welded into the cabinet framework, coupled with cover made of thin steel plate (gate) is made. This cabinet bulky, heavy, shabby appearance, and have been eliminated. With the use and the various components of the transistors, integrated circuits, ultra-small devices, the structure of the cabinet to the direction of miniaturization, the building blocks of development. The network cabinet has been in the past development of the whole panel structure has a certain size range of subracks, plug-in structure. Subracks, plug-in assembly of the arrangement are arranged horizontally and vertically arranged in two categories. The network cabinet materials commonly used thin steel plates, steel sections of various sectional shapes, aluminum and various engineering plastics. The framework of the network cabinet welded, screw connection, but also the bonding process. Produced the network cabinet for the computer network engineering, building wiring, telecommunications, paging stations, broadcasting, sound engineering, financial, intelligence community, airport and schools and other projects.
