21、T TESTS AND MEASUREMENTS Part 16-7: Mechanical tests on contacts and terminations Test 16g: Measurement of contact deformation after crimping 1 Scope and object This part of IEC 60512, when required by the detail specification, is used for testing connectors within the scope of IEC technical committ

22、ee 48. It may also be used for similar devices when specified in a detail specification. The object of this part of IEC 60512 is to detail a standard test method to assess the effectiveness of contacts to resist deformation (damage) from crimping operations. Although this test is intended for cylind

23、rical contacts, especially machined contacts, it is applicable to contacts with other geometries and construction. In which case, the detail specification shall contain sufficient detail, given under clause 4, to enable the test to be done. 2 Normative references The following referenced documents a

25、eneral examination Test 1a: Visual examination 3 Preparations 3.1 Preparation of specimen The specimen shall consist of contact-wire assemblies. The length of cable protruding from the contact shall be at least 100 mm. Number of specimens: 10 specimens for each barrel size (5 for the minimum wire si

26、ze and 5 for the maximum wire size) unless otherwise specified in the detail specification. The crimping tool(s) shall be those specified in the detail specification. If none are so specified, the contact manufacturers instructions for tooling shall be followed. In any case, full details of tooling

27、shall be given in any reports supporting claims of conformance to this part of IEC 60512. Any preconditioning given in the detail specification shall be applied.

28、8 5 3.2 Equipment A mounting collet shall be provided such that the contact may be rotated around its longitudinal axis to permit measurements at the specified points. The precision of the collet shall be such that the run-out of a steel gauge pin of 1,5 to 2,0 mm diameter measured 10 to 15 mm from

29、the collet face shall not exceed 0,1 % of such distance. 4 Test procedure The contact shall be held in a collet in region H as shown in Figure 1, so that the contact can be rotated around the longitudinal axis to permit measurements at the specified points. A suitable test arrangement is shown in Fi

30、gure 2. In the case of cylindrical contacts, readings (preferably with an indicator gauge) of the position of the contact shall be taken before and after crimping. The total excursion of the position when the contact is rotated is halved to give the deformation (or damage). Non-circular contacts sha

31、ll be measured in a similar manner. The deformation (or damage) may be similarly calculated. MX YHIEC 1005/08 Key X Twice the male contact diameter. Also used for corresponding female contact OR If not circular, corresponding characteristic dimension of each contact. Y Mid point between end of crimp

32、 barrel, or end of contact, and beginning of crimp indentation M Measurement points for contact deformation H (Example of) Holding area NOTE This should correspond to the area in which the contact is intended to be held in use.

34、ts 5.1 Before testing Visual examination according to IEC 60512-1-1 shall be carried out. There shall be no defects that would impair the validity of the test. 5.2 After testing The requirements of the detail specification for deformation shall be met. Visual examination according to IEC 60512-1-1 s

35、hall be carried out. There shall be no defects, other than any found under 5.1, that would impair the normal functioning of the component. 6 Details to be specified When this test is required by the detail specification, the following details shall be specified. a) wire type and size; b) specificati

36、on of crimping tool(s) to be used; c) area(s) of contact to be held by the mounting collet; NOTE This should correspond to the housing or insert location point(s). d) points of measurement on the contact; if other than those given in 3.2; e) values of deformation permitted, for each point of measure
