Foreword The text of document 48B/1875/FDIS, future edition 1 of IEC 60512-16-18, prepared by SC 48B, Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic
13、equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60512-16-18 on 2008-06-01. 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 whi
14、ch the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2009-03-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-06-01 Annex ZA has been added by CENELEC. _ Endorsement notice The
15、 text of the International Standard IEC 60512-16-18:2008 was approved by CENELEC as a European Standard without any modification. _ BS EN 60512-16-18:2008 2 CONNECTORS FOR ELECTRONIC EQUIPMENT TESTS AND MEASUREMENTS Part 16-18: Mechanical tests on contacts and terminations Test 16r: Deflection of co
16、ntacts, simulation 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing electomechanical components 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 pa
17、rt of IEC 60512 is to detail a standard test method to measure the deflection of a simulated contact in its cavity or housing. Although this test method is intended for cylindrical male contacts, and is particularly applicable to those where the contacts fit into an insert, which may have some elast
18、icity, its use for contacts with other geometries and housing details, is not excluded. In which case, the detail specification should contain sufficient detail, given under Clause 5, to enable the test to be done. 2 Normative references The following referenced documents are indispensable for the a
19、pplication 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.

20、: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of a housing, with an insert or other contact-receiving connector body or device. Any preconditioning given in the component detail specification shall be applied. Five such specimens shall be prepared. 3.2 Eq
21、uipment A test pin (gauge pin) shall be provided, the design of which shall replicate those parts of the contact normally fitted into the cavity that have relevance to this test. A universal testing machine suitable for the test procedure detailed in Clause 4 shall be required, equipped with all rel
22、evant test fixtures needed to hold the specimen under test. 3.3 Mounting If mounting of the specimen is appropriate, it shall be as specified in the component detail specification. The specimen shall not be mated to its corresponding, or other, component. BS EN 60512-16-18:2008 3 Figure 1 and Table

25、, at or near, the centre of the connector insert or housing. For inserts or housings having 3 or less cavities, all shall be tested. A specified force shall be applied in a manner as, or similar to, that shown in Figure 1 (which is an example). The force shall be applied at a rate not exceeding 10 N
26、/s and shall be maintained for 10 s. The foregoing shall be repeated in the opposite direction. An example is shown in Figure 1. In some cases where the geometry of the connector or insert is not symmetrical, the direction or plane of application of the forces will influence the results. In all case
27、s, the plane of application shall be that which causes the greatest deflection. BS EN 60512-16-18:2008 4 4.2 Measurements and requirements 4.2.1 Before testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects, which would impair the validity of the test.
28、4.2.2 During testing Deflection on each direction shall be recorded. The sum of these deflections shall be regarded as the total deflection. It shall not exceed that given in the component detail specification. Observation of the test pin shall be made during the test. The test pin shall not distort
29、, either temporarily or permanently, during the test to a degree that would invalidate the test. 4.2.3 After testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects to the insert or housing, other than those found under 4.2.1 that would impair the normal
30、 functioning of the component, nor shall the test pin be distorted. 5 Details to be specified When this test is required by a detail specification, the following shall be given therein: a) whether preconditioning is required; b) whether special mounting of the specimen is required; c) test pin dimen
31、sions; NOTE 1 Critical dimensions should include lever arm length, pivot point and diameters of the pin. d) force to be applied; e) point of application of force; f) total deflection (see Figure 1); NOTE 2 This may be different for fixed or free, male or female (housing or contacts). g) any deviatio
32、n from the standard test method. _ BS EN 60512-16-18:2008 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.
