Foreword The text of document 48B/1847/FDIS, future edition 1 of IEC 60512-15-5, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic equipment, was s
13、ubmitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60512-15-5 on 2008-07-01. This standard is to be read in conjunction with EN 60512-1 and EN 60512-1-100 which explains the structure of the EN 60512 series. The following dates were fixed: latest date by which the EN has to
14、be implemented at national level by publication of an identical national standard or by endorsement (dop) 2009-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-07-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the Inte
15、rnational Standard IEC 60512-15-5:2008 was approved by CENELEC as a European Standard without any modification. _ BS EN 60512-15-5:2008 2 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 15-5: Connector tests (mechanical) Test 15e: Contact retention in insert, cable nutation 1 Scope a
16、nd 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 to detail a standard test method to
17、 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 application of this document. For dated references, only the edition cited a
18、pplies. 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 examination IEC 60512-2-5: Connectors for electronic equipment Tes
19、ts 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 accessories, which do not form part of the contact system, may be removed. Any
20、 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 specified mass shown on Figure 1. If specified in the detail specific
21、ation, 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 connector has four or more contacts, three contacts shall be selected
22、 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 have all contacts installed. BS EN 60512-15-5:2008 3 3.2 Equipment Te
23、st 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 be 1,4 kg 0,02 kg. NOTE 1 If the detail specification requires specia
24、l 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. If this apparatus is used, the 45 degree angle and the 1,4 kg load
25、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 remains in a vertical position as the mounting surface is rotated. 3.3 M
26、ounting 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 connector shall be clamped to the apparatus in such a manner that d
27、oes not affect the validity of the test. NOTE See note under 4.1.2. BS EN 60512-15-5:2008 4 The connector, corresponding connector, or insert which is mounted on the apparatus, shall be prevented from rotating about its longitudinal axis. 4 Test method Unless otherwise stated in the detail specifica
28、tion, 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 constitutes one cycle. This cycle shall be repeated 100 times at a rate
29、 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 contact shall not be either temporally or permanently fully or partial
30、ly 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, it will be necessary to mount both the connector under test and
31、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) n
32、umber of connectors to be tested (if other than 3); b) preconditioning required; c) wiring of the specimen, if other than a steel cable given on Clause 3; d) if continuity monitoring is required; e) when c (above) is specified, criteria for discontinuity; f) voltage and current requirements; g) mass
33、 to be used if other than 1,4 kg; h) any deviation from the standard test method.
