6、d ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technica

7、l committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of ele

8、ctrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to th

9、e member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for ide

10、ntifying any or all such patent rights. ISO 11446-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This first edition of ISO 11446-1 cancels and replaces the third edition of ISO 11446:2004, which has been technically revised and

11、 divided into two parts, ISO 11446-1 for vehicles not intended to cross water fords and ISO 11446-2 for vehicles intended to cross water fords. ISO 11446 consists of the following parts, under the general title Road vehicles Connectors for the electrical connection of towing and towed vehicles: Part

12、 1: 13-pole connectors for vehicles with 12 V nominal supply voltage not intended to cross water fords Part 2: 13-pole connectors for vehicles with 12 V nominal supply voltage intended to cross water fords iv ISO 2012 All rights reserved INTERNATIONAL STANDARD ISO 11446-2:2012(E) Road vehicles Conne

13、ctors for the electrical connection of towing and towed vehicles Part 2: 13-pole connectors for vehicles with 12 V nominal supply voltage intended to cross water fords 1 Scope This part of ISO 11446 specifies the dimensional characteristics of, and contact allocation and tests and requirements for,

14、13-pole connectors for the electrical connection of towing and towed vehicles with 12 V nominal supply voltage and intended to cross water fords. It specifies a park socket for receiving and storing the plug when it is disconnected. 2 Normative references The following referenced documents are indis

18、 11446-1. Details not specified are at the manufacturers discretion. The contacts shall be floating and shall align to the datum position when plug and socket are engaged. 5 Application of the connector 5.1 Connector positions and free space The positions of, and free space around, the connectors sh

19、all comply with ISO 1103 and ISO 11446-1. 5.2 Contact allocation and designation The contact allocation and contact designation shall be in accordance with ISO 11446-1.

20、ble of accepting cables as defined in ISO 11446-1. Terminals accepting cables with different cross-sectional areas shall be as agreed between manufacturer and user. 5.4 Connecting cable The connecting cable shall meet the requirements of the applicable part of ISO 4141. 6 Tests and requirements 6.1

21、General Connectors according to this part of ISO 11446 shall be tested in accordance with ISO 4091. The additional immersion test in 6.2 shall be performed directly after the influence of water tests in ISO 4091. The connectors shall fulfil the requirements of ISO 4091 and the immersion of water tes

22、t in 6.2. 6.2 Immersion of water 6.2.1 Purpose This test shall ensure the prevention of water ingress into the plug and socket when the vehicle is crossing a water ford. 6.2.2 Test description Three sockets with the cover closed and three sockets with connected plugs shall be immersed in a water bas

23、in as follows: A cable of 1 000 mm 100 mm length shall be attached to the test samples for each test. The open end of the cable shall be outside of the water basin during the test. To mount the test sample, use an L-shaped support with an overall width the same as the width of the socket mounting ar

24、ea. The support shall not be deformed when used for the test and shall be able to accept the socket mounting to perform the test as required. Mount the test sample to the support according to Figures 1 and 2 and in such a way that the complete mounting surface of the socket rests upon the support an

25、d that the support does not protrude from the socket mounting surface for more than 20 mm. The test sample shall be preconditioned for 30 min at a temperature of 40 C 2 C before immersion. Immersion shall be started within 60 s after the end of preconditioning. Use a basin filled with a minimum 50 l

26、 of water with a water temperature of 15 C 3 C. Immerse the test sample in the basin at a water depth of 300 mm 10 mm as follows: With the closed cover facing upwards, vertically immerse the support with the test sample into the water filled basin to the test depth according to Figure 1 and with a s

27、peed of 1,38 m/s 0,14 m/s. If the plug is inserted, the test sample shall be immersed in the same direction. Rest at maximum depth for an exposure time of 20 min 1 min. Remove support with test sample from the water basin. A 5 A current passing through the cable and across the conductors may be used

28、 during the test to detect ingress of water by flashover. In this case, automatically stop the test. 2 ISO 2012 All rights reserved ISO 11446-2:2012(E) 6.2.3 Requirement Water shall not penetrate into the connector. Check the fulfilment of this requirement. After this requirement is fulfilled, the t

29、est samples shall fulfil the requirements of the influence of water tests of ISO 4091.
