---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:

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:
