Introduction
The mechanical structure of electronic equipment (cabinet, rack, sub-box, chassis and plug-in) is an important part of electronic equipment. For the imperial system
The mechanical structure of electronic equipment for column and metric series modular series and harmonized dimensional standards requires the establishment of a set of climatic, mechanical environment and safety requirements.
The required test specifications and requirements to meet the functional and reliability requirements of electronic equipment. The main problems it solves are.
---Specify the general climate, mechanical environment and safety test specifications and requirements for the mechanical structure of electronic equipment;
---Provide the combination of performance level and protection level of the mechanical structure of electronic equipment;
---Specify the seismic test and requirements for the mechanical structure of electronic equipment;
---Specify the electromagnetic shielding performance test specifications and requirements for cabinets and sub-boxes.
GB/T 18663 "Mechanical structure of electronic equipment metric series and inch series test" is for the mechanical structure of electronic equipment (machine
A series of environmental test standards formulated by cabinets, racks, sub-boxes, chassis and plug-ins), and it is proposed to be composed of five parts.
--- Part 1.Climatic, mechanical testing and safety requirements for cabinets, racks, sub-boxes and chassis. Designed to specify mechanical junctions of electronic equipment
Climatic, mechanical environment, and safety requirements common to organizations (cabinets, racks, sub-boxes, and enclosures).
--- Part 2.Seismic tests of cabinets and racks. Designed to specify seismic test conditions and criteria for cabinets and racks to evaluate cabinets
Or the ability of a rack mechanical structure to withstand a specific seismic intensity.
--- Part 3.Electromagnetic shielding performance test of cabinets and sub-boxes. Designed to regulate empty cabinets and sub-boxes at 30 MHz~
Electromagnetic shielding performance test and class requirements in the frequency range of 3000MHz.
--- Part 4.Combination of performance levels for modular cabinets. Designed for modular cabinets in IP codes, climate classes, static and dynamic loads
Testing, electromagnetic shielding and seismic requirements provide a combination of different protection levels for ease of selection and procurement.
--- Part 5.Seismic tests of enclosures, sub-boxes and plug-ins. Designed to specify seismic test conditions and criteria for enclosures, sub-boxes and plug-ins
standards to assess the ability of chassis, sub-box and plug-in mechanical structures to withstand specific seismic intensities.
This document presents a modular framed structural design reinforced by basic cabinet components such as doors, bottom panels, top panels, side panels and back panels.
The optimal economical solution for the cabinet system helps users to choose the cabinet that matches the performance level of the application.
