- Scope
- This part of GB/T 19520 applies to the increased positioning of printed board-type plug-ins and sub-boxes that comply with GB/T 19520.3, GB/T 19520.4 and GB/T 19520.11 with a panel minimum width of 4 times the horizontal grid pitch (4HP) /Ground pin extended features. The requirements for electrical tests are specified in GB/T 18663.1. The function of this positioning/grounding pin also counteracts the pressure exerted by means of plug-in and (or) filling panel shielding pads specified in GB/T 19520.7. A new type of subrack and plug-in (incompatible with the subrack and plug-in specified in GB/T 19520.3 and GB/T 19520.4) will be produced by supplementing this expansion feature with subracks and plug-ins. The purpose of this part is to standardize the relative dimensions of the subracks and their inserts with positioning/grounding pin expansion features added on the basis of GB/T 19520.3, GB/T 19520.4 and GB/T 19520.11, so as to ensure the interchangeability of their dimensions sex. See GB/T 18663.1 for mechanical and climate tests, and IEC/TS 61587-3 for electromagnetic shielding test.
