4、de standardization. National bodies that are members of IS0 or IEC participate in the development of international Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical com- mittees collaborate in
5、 fields of mutual interest. Other international organ- izations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards
6、adopted by the joint technical committee are circulated to national bodies for vot- ing. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

10、lity dimensions and contact number assignments 1 Scope This International Standard specifies a SO-pole connector, including the necessary mateability dimensions and the assignment of contact numbers, for use at the interface between data terminal equipment (DTE) and data circuit terminating equipmen
11、t (DCE). It is applicable where the functional characteristics of the interface conform to CCITT Recommendation V.24 and the electrical characteristics conform to ITU-T Recommendation V.12. 2 Normative references The following ITU-T (CCllT) Recommendations and International Standards contain certain
12、 provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All ITU-T (CCllT) Recommendations and International Standards are subject to revision, and parties to agreements based on this Inter
13、national Standard are encouraged to investigate the possibility of applying the most recent editions of the standards/recommendations indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards. The ITU-T Secretariat maintains a list of currently valid ITU-T
14、 (CClrr) Recommendations. CCITT Recommendation V.24: 1988, List of definitions for interchange circuits between data terminal equipment and data circuit-terminating equipment. ITU-T Recommendation V.12: 1995, Electrical characteristics for balanced interchange circuits with data signaling rates up t
15、o 52 Mbit&. ITU-T Recommendation V.130: 1995, /SDN Terminal Adapter Framework. IEC 48B (Sec.): 1993, Detail specification for a range of shielded connectors with trapezoidal shaped shells and non-removable rectangular contacts on a 7,27 x 2,54 mm (0,050 x 0,700 in) centerline. 3 Definitions For the
16、purposes of this standard the following definitions apply: 3.1 connector housing : connector into which the inserts assembled. 3.2 contact arrangement spacing and configuration of component. A part of a and contacts are : The number, contacts in a 3.3 female contact : A contact intended to make elec
17、trical engagement on its inner surface. 3.4 intermateable connectors : Two connectors that are capable of being connected to each other electrically and mechanically without regard to their performance. 3.5 latching device : A feature incorporated in certain components to provide mechanical retentio
18、n of their mating parts. 3.6 male contact : A contact intended to make electrical engagement on its outer surface. 3.7 seating plane : The surface that the connector bottoms on when fully mated. 4 Connector A 50-pole connector shall be provided for the DTUDCE interface. Figures 1 to 4 illustrate the
19、 connector. Only those dimensions that are essential for mating are shown. The DTE-DCE interface point is defined at the point between the cable connector associated with the cable attached or wired to the DTE and the equipment connector associated with the DCE (see figure 5). Figure 1 illustrates t
20、he cable connector which has 50 male contacts in a connector housing. Figure 2 illustrates the equipment connector which has 50 female contacts in a connector housing. The connector housing on the equipment connector is dimensioned to fit inside the connector housing of the cable connector (see figu
21、res 3 and 4). Figures 3 and 4 give contact numbering and illustrate the dimensions and latching mechanism for the cable and equipment connectors respectively. 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545
