BS EN 60917-2-2:1997 用于电子设备实践机械结构开发的模块化订单 剖面规范 接口配合尺寸为25毫米设备实践 详细规格 子架、机箱、背板的尺寸

This section of IEC 917-2 is a detail specification which is to be used in whole or in part in all fields of electronics where devices and systems are designed according to the sectional specification IEC 917-2. The purpose of this publication is the specification of dimensions which will ensure mechanical interchangeability of subracks, chassis, plug-in units, backplanes and front panels. The sectional specification IEC 917-2 has embodied within it a number of subrack systems based on 25 mm three-dimensional modularity and the binary additive principle for subrack heights. The dimensions in the tables of this detail specification are based on one of the subrack systems taken from the sectional specification IEC 917-2. However, all subrack systems within the sectional specification are valid in this detail specification, provided the relation-ship between the dimensions is maintained, i.e. the dimensional difference between the co-ordination dimensions Hs, Ws and Ds and dimensions Hs0, etc.; Ws0, etc., and Ds0, etc., shown in tables 1.2 and 3 are to be maintained. The subrack dimensions are related to certain cabinet/rack dimensions, see IEC 917-2-1. The front panel dimensions are related to the mounting dimensions of certain cabinets and racks, see IEC 917-2-1. Plug-in units are mounted in subracks. They serve as supports for electrical, electronic and mechanical components. The electrical connection between plug-in units and subracks is based on the use of connectors. All dimensions are given in millimetres and the drawings are first angle projections.

This section of IEC 917-2 is a detail specification which is to be used in whole or in part in all fields of electronics where devices and systems are designed according to the sectional specification IEC 917-2. The dimensions in the tables of this detail specification are a selection from the sectional specification IEC 917-2. All other sizes from the sectional specification are valid in this detail specification provided the relationship between the dimensions is maintained, i.e. the dimensional difference between the co-ordination dimensions HC, WC and DC and dimensions HCO, HC1 HC2; WCO, WC1 and DCO, OC1 shown in tables 1, 2 and 3 are to be maintained. The purpose of this publication is the specification of dimensions which will ensure mechanical interchangeability of cabinets and racks, and ensure mechanical interchangeability for sub-rack mounting. Cabinets and racks can be arranged together to form larger operating units. Application of specific cabinets or racks, attachments and accessories, such as heat exchangers, control elements, switches, etc. does not form part of this specification.

BS EN 60917-2:1994 研制电子设备机械构件用模块排序.第2部分:25 mm设备接口配合尺寸规格的实施规程

This part of IEC 917 may be applied to all fields of electronics in which equipment and installations with a modular design are used. The object of this part of IEC 917 is to define a sectional specification for the mechanical structure of a 25 mm equipment practice to provide for dimensional compatibility at mechanical interfaces with related engineering applications, e.g. plug-in units, printed boards, components, instrumentation, furniture, rooms, buildings, etc. It specifies the co-ordination dimensions and pitches for cabinets, racks, subracks and chassis of all types used for electronic equipment in, for example industrial electronics, information technology, measurement and control systems and communications. The chosen co-ordination dimensions for the mechanical structure for heights, widths and depths, lie within a homogeneous, metric modular three-dimensional grid as specified in IEC 917. In this part of IEC 917, the mounting pitches 25 mm and 2,5 mm have been used as a base to determine the interface co-ordination dimensions for the electronic equipment practice. This creates the optimum conditions for the application of computer-aided methods throughout design and manufacture such as, for instance, computer-aided planning, development, manufacturing, testing and installation. The cabinets and racks in this part of IEC 917 represent a specific structural form which takes into consideration for instance the installation of subracks and chassis. The determined interface co-ordination dimensions for the overall outside and aperture dimensions of subracks provide space for independently created plug-in units to be installed. These plug-in unit dimensions shall follow the rules of IEC 917-0 and IEC 917 and are to be determined in detail specifications. The connector system used (0,5; 1,0; 2,0; 2,5 mm, etc. connector grid) and the special application requirements are to be determined in associated detail specifications. Further standards may be used in conjunction with this part of IEC 917: IEC 297-1:1986, Dimensions of mechanical structures of the 482.6 mm (19 inch) series -Part 1: Panels and racks. IEC 297-2:1982, Dimensions of mechanical structures of the 482,6 mm (19 inch) series -Part 2: Cabinets and pitches of rack structures.
