Introduction

IEC 60297 (all parts) specifies the mechanical construction and dimensions of 19in cabinets and racks and their compatible bays and cabinets. Cabinet The combined use of 19in, based on rack, subrack and chassis, is widely used in all industrial electronics fields worldwide. IEC 60917 (all parts) is based on metric modular sequence sizes and also specifies the structure and structure of metric cabinets, racks, subracks and enclosures. Connection size. Subsequent development of IEC 60917 (all parts) compared to IEC 60297 (all parts), provided on a metric basis More reasonable design practice for the box and chassis. To meet the needs of the combined use of two mechanical structures, the IEC 60297 series (19in standard) and the IEC 60917 series (metric standard), Caused the requirement to install a 19in subrack or chassis in a metric standard cabinet or rack, and vice versa, ie in a 19in rack or rack Install a metric box or chassis. To address this requirement and need, it is necessary to determine the appropriate flange mounting position for the 19in or metric box or chassis for the cabinet or rack. Interface size. These regulations provide an economical solution for installing electronic equipment in existing cabinets or racks. In addition, for electromechanical Designers have the flexibility to develop a structural system that is suitable for installation in both standard series. In order to meet this market need, this section specifies the size of the 19in box or chassis for metric cabinets or racks. Inch, and the size of the metric box or chassis installed in a 19in cabinet or rack is specified in additional IEC 60917-2-4). Electronic equipment mechanical structure 482.6mm (19in) Series Mechanical Structure Dimensions - Part 3-106. Application In accordance with IEC 60917-2-1 metric cabinets or Fitted dimensions for the chassis and chassis of the rack

1 Scope

This section of GB/T 19520 specifies the flange mounting dimensions for a 19in subrack or enclosure that can be mounted in a metric cabinet or rack. The additional dimensions of the subrack or enclosure comply with IEC 60297 (all parts) and the additional dimensions of the metric cabinet or rack comply with IEC 60917 (all parts). EMC, seismic, climatic, and environmental requirements and tests are specified in IEC 61587 (all parts). The diagrams used in this section are not intended to guide product design, and only those dimensions specified in those standards should be used. The terminology used is in accordance with IEC 60917-1.
