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 2-1. Sectional specification - Interface co - ordination dimensions for the 25mm equipment detailed specifications and dimensions of the cabinet rack;

--- Part 2-2. Sectional specification - Interface co - ordination dimensions for the 25mm equipment detailed specification into me, chassis, backplane, and panel Size plug-in;

--- Part 2-3. 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 19290 Part 2-1.

This section identical with IEC 60917-2-1:1993 "in the development of electronic equipment - Part 2 isomer mechanical structure number sequence mode. dividers Fan Interface coordination dimensions for the 25mm equipment of the first one. Detailed specifications and dimensions of the cabinet rack "(in English).

1 Scope

This section is full or in part in accordance with all the electronics field specification GB/T 19290.2-2003 design devices and systems A detailed specification.

This section table size selected specification GB/T 19290.2-2003. Retained all the other specification of this section provides foot Effective size inch relations, retains the coordination dimension Hc Tables 1 to 3 represented, Wc and Dc and size Hc0, Hc1, Hc2, Wc0, Wc1 and Dc0, the difference in size between the Dc1.

This part of the purpose is to regulate to ensure that the cabinet or rack, and insert those dimensions box with mechanical interchangeability. Cabinets and racks it can be configured together to form a larger unit of work.

Application specific cabinet or rack, fittings and accessories (such as heat exchangers, control units, switches, etc.), not as an integral part of this section.
