3、 specialized system for worldwide 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 techni
4、cal com- mittees collaborate in 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 techno!ogy, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1.
5、 Draft International Standards 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. International Standard ISO/IEC 11569 was prepared by Joint Techni

26、ment : The number, spacing and configuration of contacts in a component. 3.3 female contact : A contact intended to make electrical engagement on its inner surface. 3.4 intermateable connectors : Two connectors that are capable of being connected to each other electrically and mechanically. 3.5 latc
27、hing device : A feature incorporated in cer- tain components to provide mechanical retention of their mating parts. 3.6 male contact : A contact intended to make elec- trical engagement on its outer surface. 3.7 seating plane : The surface that the connector bottoms on when it is fully mated. 4 Conn
28、ector A 26-pole connector shall be provided for the DTE/DCE interface. Figures 1 to 4 illustrate the connectors. Only those dimensions that are essential for mating are shown. The DIE-DCE interface point is defined at the point between the cable connector associated with the cable attached to the DT
29、E and the equipment connector associated with the DCE. Figure 1 illustrates the cable connector which has 26 male contacts in a connector housing. Figure 2 illus- trates the equipment connector which has 26 female contacts in a connector housing. The connector housing on the equipment connector is d
30、imensioned to fit inside the connector housing of the cable con- nector (see figures 3 and 4). Figures 3 and 4 give contact numbering and illustrate the dimensions and latching mechanism for the cable and equipment connectors respectively. 5 Assignment of contacts The assignment of contact numbers i
