Foreword

GB/T 19290 "in the development of mechanical structures for electronic equipment modulus sequence" is divided into the following five sections.

--- Part 1. Generic specification;

--- Part 2. Sectional specification - Interface coordination dimensions 25mm equipment practice;

--- Part 3. Sectional specification - Interface co - ordination dimensions for the 25mm equipment detailed specifications and dimensions of the cabinet rack;

--- Part 4. Sectional specification - Interface co - ordination dimensions for the 25mm equipment detailed specification into me, chassis, backplane, and panel Size plug-in;

--- Part 5. Sectional specification detailed specification of the interface coordination dimensions for the 25mm equipment expansion subracks, chassis, backplanes, Size panels and plug-ins.

This section GB/T Part of 419,290.

1 Scope

GB/T 19290 in this section is partially or fully applied to all areas of electronics, according to GB/T 19290.2 electrical design specification Detail specification sub-assemblies and systems.

The purpose of this section is to ensure that the plug-in box, chassis, plug-ins, back panel and mechanical interchangeability dimensions specifications.

In the specification GB/T 19290.2, it has been included in the value of three-dimensional model based on the number of 25mm plug box system, as well as into me Doubling the height of the principles.

Size listed in the tables in this section is based on GB/T 19290.2 insertion of a box system. However, as long as the relationship between the size Unchanged, that the table size, etc. Table 1 to coordinate with the given size HS 3 HS0 etc., WS and WS0, and the like DS and DS0 difference between Held constant, the detailed specifications for all plug-in box system containing the specification are valid.

Plug-in box associated with the determined size of the cabinet and rack installation size, see GB/T 19290.3.

Panel size and the determined dimensions associated cabinets and racks, see GB/T 19290.3.

To load a plug-in box support for electric and electronic components and mechanical parts of the plug. Electrical plug and plug connection depends on the connection between the tank it is used.

All dimensions in millimeters Inset first angle projection.
