24、odular pitch of 25 mm and integrated shielding function, applicable for transverse packing density of 15 mm, having a basic grid of 2,5 mm in accordance with IEC 60917-1 FOREWORD 1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all nati
25、onal electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
26、Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collabo
27、rates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion
28、on the relevant subjects since each technical committee has representation from all interested National Committees. 3)The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and th
29、ey are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Sta
30、ndard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to
31、the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61076-4-108 has been prepared by subcommittee 48B: Connectors, of IEC technica
32、l committee 48: Electromechanical components and mechanical structures for electronic equipment. The text of this standard is based on the following documents: FDISReport on voting 48B/1122/FDIS48B/1170/RVD Full information on the voting for the approval of this standard can be found in the report o
33、n voting indicated in the above table. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated when a new edition is prepared. 6 61076-4-108 IEC:2002(E) The QC number that appears on the front cover of this publicat
34、ion is the specification number in the IEC Quality Assessment System for Electronic Components (IECQ). This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. Annex A is for information only. The committee has decided that the contents of this publication will remain unc
35、hanged until 2004. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 61076-4-108 IEC:2002(E) 7 CONNECTORS FOR ELECTRONIC EQUIPMENT Part 4-108: Printed board connectors with assessed quality Detail specification for cable-to-board connectors, wit

IEC 395/02 8 61076-4-108 IEC:2002(E) 1 General data This specification describes adapter connectors of modular metric construction in conformance with IEC 60917-1. Interface connectors and cable connectors are used to make the electrical connection between a clos
40、ed functional unit, for example a subrack, and its environment. The modular construction and the various connector styles enable a suitable connector to be used in equipment practices for electronic equipment such as data systems, communications technology, telecom- munications engineering and safet
41、y and security systems, power engineering and automation technology. Throughout this specification all dimensions are in millimetres. 1.1 Recommended method of mounting The connectors are used for connecting a printed board to a cable (see also figure 1). The connectors are matched to the 2,5 mm con
42、tact grid. They can be mounted in an existing grid coordinate system horizontally or vertically or overlapping from module to module or from subrack to subrack. Care shall be taken to ensure that the contact areas of the male contacts match the position of the female contacts. The engaging areas of
43、the male contacts on the rear of a backplane correspond to the male contact dimensions according to IEC 61076-4-100. NOTE In view of the large number of different mounting and application options, the contact quality between male and female contacts must be guaranteed. In the case of a subrack, for
44、example, there are three mounting options: a)Rear of the backplane b) Module side of the backplane c)Front of the module Fixed connectors: For application on the rear of a backplane, a male connector body (preferably of flanged cons- truction) is pushed over the rear plug-in connections of male cont
45、acts which have already been pressed in, for example over the terminals of a male connector according to IEC 61076-4-100, and secured in position. For use on the module side of a backplane, a male connector body can be mounted in the same way over press-in male contacts. Apart from flange mounting,
46、the male connector body can also be fixed unsupported or directly to the male contacts. For application on the side of a module or at the rear of a backplane, an interface male connector (preferably without flange) can be pressed into metal-plated holes in the backplane. For application at the front
47、 of a module, a male connector body shall be equipped with male contacts which are mounted, for example pressed in, on the module printed board with terminals bent at right angles. Free connectors: The female connector equipped with female contacts is secured in a connector housing at which the cabl
48、e is mounted with strain relief. The shielding braid of a cable shall be conductively connected to the connector housing consisting of shielded metal caps. The individual wires of a cable shall be connected at the female contacts directly by means of crimped or insulation displacement connections. 6
