The mechanical structure of electrical and electronic equipment is an important part of electrical and electronic equipment: To realize and improve electrical and electronic equipment Functional elements such as versatility, interchangeability and reliability, GB/T 19520 regulates the dimensions and interfaces of mechanical structures of electrical and electronic equipment: Regulation: The main problems it solves are: ---Specify the basic dimensions of panels, sub-boxes, chassis, racks and cabinets; ---Specify the basic size relationship between the plug-in box and the plug-in; ---Specify the dimensions and interfaces of accessories such as puller handles, coding keys, positioning pins, etc:; ---Specify the interface dimensions related to plug-in boxes, plug-ins and connectors; ---Specify the dimensions of 1U height chassis, miniaturized plug-ins and plug-ins, R-type plug-ins and plug-ins, and chassis of embedded computing equipment; ---Specifies the dimensions of residential racks and cabinets for smart homes: GB/T 19520 is a series of dimensional standards for the mechanical structure of electrical and electronic equipment, and is intended to consist of 11 parts: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-100: panels, plug-in boxes, chassis, Basic dimensions of racks and cabinets: The purpose is to specify 482:6mm (19in) series panels, plug-in boxes, chassis, racks and cabinets basic size: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-101: plug-in boxes and their plug-ins: Head The purpose is to stipulate the basic dimensional relationship of the 482:6mm (19in) series plug-in boxes and their plug-ins to ensure their interchangeability: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-102: Plug and puller handle: Purpose It specifies the size of the puller handle for use with the 482:6mm (19in) series subracks and plug-ins: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-103: Coding keys and positioning pins: The purpose is to specify the interface dimensions of coding keys and locating pins for use with 482:6mm (19in) series subracks and inserts: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-104: Connector-based plug-in box and plug-in interface dimensions: The purpose is to specify the interface dimensions related to the 482:6mm (19in) series of plug-in boxes and plug-ins and connectors: The relationship between the size and the installation spacing of the plug-in box and the printed board type plug-in and the backplane: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-105: 1U height chassis dimensions size and design requirements: The purpose is to specify the dimensions and dimensions of a 1U height chassis installed on a 482:6mm (19in) rack or cabinet: Carrying weight and installation method: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-106: Applicable to compliance with IEC 60917-2-1 Adaptable dimensions for plug-in boxes and chassis in metric cabinets or racks: Intended for installation in metric cabinets or The 482:6mm (19in) plug-in box of the rack and the flange mounting dimensions of the chassis: ---Electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-107: Miniaturized plug-in boxes and plug-ins size of: The purpose is to standardize the use of connectors and other connectors specified by PICMGMicroTCA:0 and IEC 61076-4-116 Dimensions of miniaturized jacks and plug-ins for two-piece connectors and their interface dimensions: --- Electrical and electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-108: R-type plug-in box and The size of the plug-in: The purpose is to specify the specifications of R-type sub-boxes and plug-ins (reinforced sub-boxes and plug-ins) that can be used in harsh environments: size: --- Electrical and electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-109: Embedded computing The device's chassis size: The purpose is to specify the dimensions and physical properties of embedded computing device chassis and their printed boards: ---Electrical and electronic equipment mechanical structure 482:6mm (19in) series mechanical structure dimensions Part 3-110: for smart houses Residential racks and cabinets: The purpose is to specify the dimensions, installation specifications, environmental requirements and safety of residential racks and cabinets for smart homes: All requirements: This document establishes alternative dimensions and characteristics for sub-boxes and their plug-ins by comparison with IEC 60297-3-101: These alternatives are For a stronger design of the load-bearing parts of the plug-in box: The plug-in has positioning pins and is fastened with M3 screws: Integrated chassis is also included in this article part of the package to optimize thermal management performance: Electrical and electronic equipment mechanical structures 482:6mm (19in) series mechanical structure dimensions Part 3-108: Dimensions of Type R sub-boxes and inserts

1 Scope

This document specifies the dimensions and characteristics of type R sub-boxes and plug-ins: R-type plug-in box and plug-in, namely 482:6mm (19in) series mechanical junction Ruggedized versions with enhanced vibration and shock resistance and/or improved electromagnetic compatibility (EMC) performance for use in more severe environments: This results in a plug-in box standard that is externally compatible with IEC 60297-3-100 but internally basically incompatible with IEC 60297-3-101: and Compared with IEC 60297-3-101 (the test configuration and load regulations are selected from IEC 61587-1 and IEC 61587-5), R-type plug-in box, integrated chassis And the dimensions and features covered by the plug-in reflect a higher level of ruggedness:
