19、cal) Test 15g: Robustness of protective cover attachment 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-ope

20、ration 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 referred to a

21、s “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 this pr

22、eparation. 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 international co

23、nsensus 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 effort

24、s 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 Publication

25、s 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 and ca

26、nnot 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 experts and

27、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 Publicati

28、on 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 Publicati

29、on may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60512-15-7 has been prepared by subcommittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for

30、electronic equipment. This standard cancels and replaces test 15g 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. 60512-15-7 IEC:2008 3 The text of this standard is based on the foll

31、owing documents: FDIS Report on voting 48B/1849/FDIS 48B/1901A/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 pa

32、rts 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 site unde

At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition; or amended 4 60512-15-7 IEC:2008 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 15-7: Connector tests (mechanical)

34、Test 15g: Robustness of protective cover attachment 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 o

35、bject of this document is to detail a standard test method to assess the ability of a connector cover and its attachment to withstand mechanical stresses. NOTE Such a cover may be protective in any sense. 2 Normative references The following referenced documents are indispensable for the application

36、 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 for electronic equipment Tests and measurements Part 1-1: General examination Test 1a: Visual e

37、xamination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a cover fixed to its connector or a specified test fixture. Any preconditioning given in the detail specification shall be applied. 3.2 Equipment For the application of the loads, a suitable device able to provide th

38、e controls on the loads (intensity, rate of increase, time of constant load application) shall be required (e.g.: a universal materials testing machine). NOTE If the detail specification requires special preconditioning of the specimen, all the necessary equipment detailed in the relevant documents

39、describing such conditioning would also be required. 3.3 Mounting If mounting of the specimen is appropriate, it shall be as specified in the detail specification. 4 Test method Unless otherwise stated in the detail specification, 3 connectors shall be tested. 60512-15-7 IEC:2008 5 4.1 Procedure The

40、 specified force shall be applied in the direction of the normal removal direction of the cover. In the case of screwed caps, this shall not include an unscrewing torque. The specified force shall then be applied perpendicular to the normal removal axis of the cover. This shall be done in four direc

41、tions in the same plane, mutually at right angles to each other. In the case of screwed caps only, one such force shall be applied. In some designs there may be a disadvantageous or worst case direction for the application of this force. If so at least one of the four directions shall be in this dir

42、ection. The load shall be applied at a rate of 25 mm/min. The maximum load shall be applied for 5 minutes. The force shall then be removed. 4.2 Measurements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be done. 4.2.2 During testing No malfunction of the cover or its attac

43、hment system shall occur. 4.2.3 After testing Visual examination according to IEC 60512-1-1 shall be done. Special attention shall be given to the operation of sealing, coupling and retaining devices. 5 Details to be specified When this test is required by a detail specification the following shall

44、be given therein, a) number of connectors to be tested (if other than 3); b) preconditioning required; c) loads to be applied, point of application may be specified; d) details of test fixture, if corresponding connector is not to be used; e) if any displacement is permitted; f) any deviation from t
