IEC 395/02 Page6 EN610764108:2002)E(2002:CEI 801-4-67016 7 1 General data This specification describes adapter connectors of modular metric construction in conformance with IEC 60917-1. Interface connectors and cable

37、 connectors are used to make the electrical connection between a closed 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,

38、communications technology, telecommunications engineering and safety 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 cabl

39、e (see also figure 1). The connectors are matched to the 2,5 mm contact 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 contact

40、s match the position of the female contacts. The engaging areas of 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 an

41、d female contacts must be guaranteed. In the case of a subrack, for 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 co

42、nstruction) is pushed over the rear plug-in connections of male contacts 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 th

43、e same way over press-in male contacts. Apart from flange mounting, 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 in

44、to metal-plated holes in the backplane. For application at the front 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

45、 female contacts is secured in a connector housing at which the cable 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 di
