Foreword The text of document 48B/1846/FDIS, future edition 1 of IEC 60512-15-4, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic equipment, was sub

13、mitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60512-15-4 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 be

14、 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or by endorsement (dop) 2009-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-07-01 Annex ZA has been added by CENELEC.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 Intern

15、ational Standard IEC 60512-15-4:2008 was approved by CENELEC as a European Standard without any modification. _ BS EN 60512-15-4:2008 2 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 15-4: Connector tests (mechanical) Test 15d: Contact insertion, release and extraction force 1 Scope

16、 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 to detail a standard test method

17、to determine the forces required to insert contact into, and extract them from, their normal position in the intended connector. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For

18、 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 3 Preparations 3.1 Preparation of specimen The specimen shall con

19、sist of a connector with its terminations, wired as specified in the detail specification. Any accessories, which do not form part of the contact system, may be removed. Any preconditioning given in the detail specification shall be applied. Any contact retention device shall be placed in such a pos

20、ition as not to influence the test, except where the use of such devices is part of the normal insertion and extraction process. All contacts shall be installed except for those to be used for the test. 3.2 Lubricant or sealing substance For the application and measurement of the forces a suitable d

21、evice able to provide the controls on the loads 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 describing such conditioning would also b

22、e required. 3.3 Equipment Insertion and extraction tools, when specified by the detail specification, shall be provided. 3.4 Mounting If mounting of the specimen is appropriate, it shall be as specified in the detail specification. BS EN 60512-15-4:2008 3 4 Test method 4.1 Procedure Unless otherwise

23、 stated in the detail specification, 3 connectors shall be tested. 4.1.1 Selection of contact for test 20 % of the contacts, but not less than 6, shall be selected at random provided that at least one contact is near the periphery, and one near the centre of the connector. For connectors having six

24、or less contacts, all contacts shall be used. 4.1.2 Insertion A contact shall be inserted into its cavity using the insertion tool, lubricant and any other aid specified in the detail specification. Instructions for this procedure given, or referred to, in the detail specification, shall be followed

25、. It shall be ascertained that the contacts are in the intended position and are latched or locked into place. The foregoing procedure shall be applied to the selected contacts in turn. 4.1.3 Extraction In a similar manner to the insertion, the selected contacts shall be removed. In the case of non-

26、removable contacts, this part of the test shall not apply. 4.1.4 Repeated insertion and extraction The foregoing constitutes one insertion and extraction cycle. If specified in the detail specification, it shall be repeated a specified number of times. 4.2 Measurements 4.2.1 Before testing Visual ex

27、amination according to IEC 60512-1-1 shall be done. 4.2.2 During testing The forces required to achieve insertion and extraction (release) of the contact shall be measured and recorded. The insertion and extraction forces shall not exceed those given in the detail specification. 4.2.3 After testing

28、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) wiring of the specimen; d) mounting

29、of the specimen, if required; e) specification and application method of any lubricant or sealant to be used; BS EN 60512-15-4:2008 4 f) maximum insertion and extraction forces; g) number of insertion and extraction, if other than one; h) if the contact is non-removable; i) any deviation from the st

30、andard test method. _ BS EN 60512-15-4:2008 5 Annex ZA (normative) Normative references to international publications with their corresponding European publications The following referenced documents are indispensable for the application of this document.
