19、echanical) Test 15e: Contact retention in insert, cable nutation FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote internationa

20、l co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter refer

21、red to as “IEC Publication(s)”). 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

22、this preparation. IEC collaborates 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 IEC on technical matters express, as nearly as possible, an internati

23、onal consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable

24、 efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publ

25、ications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval

26、 and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual exper

27、ts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Pu

28、blication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Pu

29、blication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60512-15-5 has been prepared by subcommittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structur

30、es for electronic equipment. This standard cancels and replaces test 15e of IEC 60512-8, issued in 1993. This standard is to be read in conjunction with IEC 60512-1 and IEC 60512-1-100 which explains the structure of the IEC 60512 series. The text of this standard is based on the following documents

31、: FDIS Report on voting 48B/1847/FDIS 48B/1899/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 60512-15-5 IEC:2008 3 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of

32、all parts of the IEC 60512 series, under the general title Connectors for electronic equipment Tests and measurements, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web sit

33、e under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition; or amended. 4 60512-15-5 IEC:2008 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 15-5: Connector tests (mecha

34、nical) Test 15e: Contact retention in insert, cable nutation 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of technical committee 48. It may also be used for similar devices when specified in a detail specificati

35、on. The object of this document is to detail a standard test method to verify the capability of the contact retention system to withstand dynamic mechanical loading of the contacts that tends to dislodge them. 2 Normative references The following referenced documents are indispensable for the applic

36、ation of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

37、ual examination IEC 60512-2-5: Connectors for electronic equipment Tests and measurements Part 2-5: Electrical continuity and contact resistance tests Test 2e: Contact disturbance 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a connector with its terminations. Any accessor

38、ies, which do not form part of the contact system, may be removed. Any preconditioning given in the detail specification shall be applied. The contacts to be tested shall be attached to a flexible stranded steel cable of a diameter suitable for attachment to the contact under test and to support the

39、 specified mass shown on Figure 1. If specified in the detail specification, a specified copper or other cable may be used. NOTE It may be necessary to enlarge the end of the cable before attachment to the contact(s), in order to prevent the cable pulling out of the contact during testing. Where the

40、 connector has four or more contacts, three contacts shall be selected at random provided that two contacts shall be near periphery and one near the centre of the connector insert or housing. All other contacts shall be installed. In the case where a corresponding connector is to be used, this shall

41、 have all contacts installed. 60512-15-5 IEC:2008 5 3.2 Equipment Test apparatus such as that shown in Figure 1 shall be provided. The mass shall be sufficient to provide tension in the cable without deforming the specimen under test. Unless otherwise stated in the detail specification, this shall b

42、e 1,4 kg 0,02 kg. NOTE 1 If the detail specification requires special preconditioning of the specimen, all the necessary equipment detailed in the relevant documents describing such conditioning would also be required. NOTE 2 Another possible apparatus for this test is that of IEC 60999-1, Figure 1.

43、 If this apparatus is used, the 45 degree angle and the 1,4 kg load shall be used. 45 5 2 3 XXXX1 IEC 722/08 Key 1 connector under test 2 swivel pulley 3 mass e.g. 1,4 kg Figure 1 Example of test apparatus NOTE 3 In this example, the connector is mounted in such a way that axis XX in the figure rema

44、ins in a vertical position as the mounting surface is rotated. 3.3 Mounting Connectors having no suitable mounting flange shall be mated to their corresponding fixed connector, which shall be mounted on the apparatus. In the case of neither connector having suitable mounting means, the corresponding

45、 connector shall be clamped to the apparatus in such a manner that does not affect the validity of the test. NOTE See note under 4.1.2. 6 60512-15-5 IEC:2008 The connector, corresponding connector, or insert which is mounted on the apparatus, shall be prevented from rotating about its longitudinal a

46、xis. 4 Test method Unless otherwise stated in the detail specification, 3 connectors shall be tested. The connector shall be arranged on the apparatus as described in Clause 3 and shown on Figure 1. The apparatus shall be operated such that the connector under test is rotated through 360. This const

47、itutes one cycle. This cycle shall be repeated 100 times at a rate of 10 to 20 cycles per minute. This procedure shall be repeated for the other contacts. 4.1 Measurements and requirements 4.1.1 Before testing Visual examination according to IEC 60512-1-1 shall be done. 4.1.2 During testing The cont

48、act shall not be either temporally or permanently fully or partially dislodged from their normal position. If required by the detail specification, monitoring for electrical continuity may be done. In which case this shall be done according to IEC 60512-2-5. NOTE In the case of continuity monitoring

49、, it will be necessary to mount both the connector under test and its corresponding half, irrespective of the nature of mounting means provided by the connectors. 4.1.3 After testing Visual examination according to IEC 60512-1-1 shall be done. 5 Details to be specified When this test is required by a detail specification, the following shall be given therein: a) number of connectors to
