16、s and terminations Test 16h: Insulating grip effectiveness (crimped connections) 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

17、a detail specification. The object of this part of IEC 60512 is to detail a standard test method to assess the effectiveness of an insulation grip to hold the insulation of a cable/wire under specified conditions. 2 Normative references The following referenced documents are indispensable for the ap

18、plication 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:

19、 Visual examination 3 Preparations 3.1 Preparation of specimen The specimens shall consist of even quantities of cable with the largest insulation specified for the grip, and the smallest. The specimens shall consist of a crimp contact or terminal end and the specified cable(s); these shall be prepa

20、red (crimped) in the manner given in the relevant detail specification or if none are given, the manufacturers instructions. The crimp contact/terminal end shall be crimped in the manner previously stated, but the cable/wire shall be held by the insulation grip only. NOTE Either crimping a separate

21、piece of wire or cutting the conductor after crimping may achieve this. The un-stripped cable/wire shall be at least 100 mm in length. If lubricant is required by the component detail specification, this shall be applied in the manner so specified. Similarly, if the manufacturers crimping or other a

22、ssembly devices specify a lubricant, this shall be applied. 3.2 Equipment A mandrel having a diameter equal to that as specified for the flexibility test of the relevant wire/cable shall be provided. BS EN 60512-16-8:2008 3 3.3 Pre-conditioning Any pre-conditioning of the samples required by the app

23、licable detail specification shall be applied. 4 Test method 4.1 Temperature It is recognized that temperature has a significant effect on the flexibility of cable insulation. These tests shall be carried out under normal laboratory conditions unless otherwise stated in the relevant detail specifica

24、tion. 4.2 Procedure The crimp(ed) contact/terminal shall be held tangential to the mandrel. The wire shall be wound around the mandrel for at least one complete turn and shall be in contact with the mandrel where it enters the insulation grip. Sufficient tension, as specified in the relevant detail

25、specification, shall be applied to the wire to keep it in contact with the mandrel. A test made by first winding the wire in one direction then in the opposite direction shall be considered one cycle. This cycle shall be done at least ten times. The rotational position of the specimen relative to th

26、e direction of bending shall be varied during each cycle such that forces are applied in at least four directions mutually at right angles to each other relative to the grip. NOTE It is recognized that grip devices have a best and worst direction of support. The above requirement is intended to test

27、 in both the best and worst directions. 4.3 Measurements and requirements 4.3.1 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. 4.3.2 During testing None. 4.3.3 After testing The conductor shall

28、 be withdrawn from the cable/wire and examined for damage (caused by either the grip crimping process or the testing). This may be done by stripping the insulation from the far end of the cable/wire and applying a tensile load between the bared conductor and the crimp terminal. Visual examination ac

29、cording to IEC 60512-1-1 shall be done. There shall be no defects, other than those found under 4.3.1, which would impair the normal functioning of the component. 5 Details to be specified When this test is required by the detail specification, the following details shall be specified: a) whether pr

30、econditioning is required; b) cable/wire/insulation size(s) to be used; c) number of specimens to be tested for each grip size; BS EN 60512-16-8:2008 4 d) details of assembly tooling; e) whether lubricant, including that for application tooling, is to be used; f) whether special mounting of the spec

31、imen is required; g) tension to be applied; h) number of cycles (if other than 10); i) any deviation in from the standard test method. _ BS EN 60512-16-8:2008 5 Annex ZA(normative) Normative references to international publications with their corresponding European publications The following referen
