19、t retention in housing (torsional) 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 international co-operation on all question

20、s 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 referred to as “IEC Publication(s)”

21、). 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 this preparation. IEC collabor

22、ates 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 international consensus of opinion on t

23、he 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 efforts are made to ensure th

24、at 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 Publications transparently to the

25、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 and cannot be rendered respon

26、sible 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 experts and members of its technica

27、l 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 Publication or any other IEC Pub

28、lications. 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 Publication may be the subject o

29、f patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60512-15-3 has been prepared by subcommittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. T

30、his standard cancels and replaces test 15c 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. 60512-15-3 IEC:2008 3 The text of this standard is based on the following documents: FDIS R

31、eport on voting 48B/1845/FDIS 48B/1897/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. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 60512 ser

32、ies, 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 site under “http:/webstore.iec.ch

33、“ 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 60512-15-3 IEC:2008 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 15-3: Connector tests (mechanical) Test 15c: Insert retent

34、ion in housing (torsional) 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 specification. The object of this document is

35、 to detail a standard test method to assess the effectiveness of the insert retaining system to withstand torsional stresses likely to be encountered during normal use. NOTE The test method detailed in this document is a companion to the one detailed in IEC 60512-15-2 (see bibliographic reference).

36、2 Normative references The following referenced documents are indispensable for the application 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. IEC 60512-1-1, Connectors

37、for electronic equipment Tests and measurements Part 1-1: General examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a connector with its terminations, and wired if so specified in the detail specification. Cable fittings and accessories

38、shall not be fitted. Any preconditioning given in the detail specification shall be applied. 3.2 Equipment For the application of the torsional loads, a suitable device able to provide the controls on the torque (intensity, rate of increase, time of constant torque application) shall be required (e.

39、g.: a torsion testing machine). NOTE 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 3.3 Mounting Mounting of the specimen shall be as specified in the det

40、ail specification. 60512-15-3 IEC:2008 5 4 Test method Unless otherwise stated in the detail specification, 3 connectors shall be tested. 4.1 Procedure The housing of the connector shall be fixed in such a manner as not to influence the insert retention means. A specified torque shall be applied uti

41、lising the test fixture specified in the detail specification. The torque shall be applied at a rate of 0,5 Nm/s until the specified torque is achieved and held at that value for 1 min. 4.2 Measurements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be done. 4.2.2 During te

42、sting The displacement caused by the specified torque shall be measured. Any residual displacement after the specified torque is removed shall be measured. These displacements shall be recorded. The angular displacement of the insert if any shall not exceed that which may be given in the detail spec

43、ification. 4.2.3 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) the number of connectors to test if other than 3; b) preconditioning required; c) fitme

44、nt of contacts and wiring of the specimen; d) mounting of the specimen; e) test fixture to be used; f) torque to be applied; g) permitted displacement, if any (during and after the test); h) any deviation from the standard test method. 6 60512-15-3 IEC:2008 Bibliography IEC 60512-15-2, Connectors fo
