13、dard has been prepared under the direction of the Electronic Components Standards Policy Committee. It is identical with IEC760:1989 Flat, quick-connect terminations including Amendment 1:1993 published by the International Electrotechnical Commission (IEC). It supersedes BS 5057:1988, which was ide
14、ntical with IEC760:1983 and which is withdrawn. IEC 760:1989 was prepared by IEC Sub-Committee 48B: Connectors, of IEC Technical Committee No. 48: Electromechanical components for electronic equipment. The United Kingdom participation in the drafting was provided by Sub-Committee ECL/21/2 “LF Connec
15、tors” of Technical Committee ECL/21 “Electromechanical components for electronic equipment.” Any reference to IEC page numbers in the text should be ignored. Refer to the contents on pages i and ii for the page numbers of the tables and figures. The Technical Committee has reviewed the provisions of
16、 IEC512-2:1985 and IEC512-7:1988, to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsibl
17、e for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

21、uick-connect terminations consisting of male tabs with hole or dimple detents and the mating female connectors. For reasons of safety, it is recommended that quick-connect terminations beyond the scope of this standard shall not be interchangeable with those listed in Clause 4. This standard establi
22、shes uniform requirements for the dimensions, performance characteristics and test program. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.

27、nations an electrical connection consisting of a male tab and female connector which can be readily inserted and withdrawn without the use of tools 3.2 test tab a male tab manufactured to close tolerances for the specific purpose of conducting mechanical tests with production female connectors. The
28、use of test tabs has been found to produce more consistent test results 3.3 male tab that portion of a quick-connect termination which receives the female connector 3.4 female connector that portion of a quick-connect termination which is pushed onto the male tab 3.5 detent a dimple (depression) or
29、hole in the male tab which acts to engage a raised portion on the female connector, thus providing a latch for the mating parts 3.6 reference point a specially marked point, used when making electrical test measurementsIEC760:1989 2 BSI 03-1999 4 Classification into groups Flat quick-connect termina
30、tions are classified into groups according to the nominal width of the male tabs. This standard covers the following groups: 2.8 mm (0.110 in) series. 4.8 mm (0.187 in) series. 5.2 mm (0.205 in) series (not recommended for new designs). 6.3 mm (0.250 in) series. 9.5 mm (0.375 in) series. 5 Values of
31、 current The currents shown in Figure 8, are for test purposes only. Operating values depend upon the application and can be estimated through an analysis of the curves shown on Figure 14, Figure 15, Figure 16, Figure 17, Figure 18 and Figure 19. 6 Marking Each male tab or female connector shall hav
32、e the following information clearly and indelibly marked uponit: Mark of origin (manufacturers name or trade mark). 7 Dimensions The dimensions of the male tabs and female connectors shall comply with those specified herein. Dimensions for male tabs are presented in Figure 1, Figure 2a, Figure 2b an
33、d Figure 3. Dimensions for the female connectors are given in Figure 4 andFigure 4a. The shape of the various parts may deviate from those given in the figures, provided that the specified dimensions are not influenced. The dimensions are intended to permit production in either the millimetre or inc
34、h system of units.IEC760:1989 BSI 03-1999 3 NOTE 1For detent dimensions F, M and N, see Figure 2a, Figure 2b and Figure 3. NOTE 2Bevel A 45 need not be a straight line if it is within the confines shown, or it may be a segment of a circle having a radius P and a segment altitude A. NOTE 3All portion
35、s of the tabs shown shall be flat and free of burrs or raised plateaus, except that there may be a raised plateau over the stock thickness of 0.025 mm (0.001 in) per side, in an area defined by a line surrounding the detent and distant from it by1.3mm (0.051 in). NOTE 4Dimension L is not specified a
36、nd may vary as required by the application. NOTE 5The material shall be half-hard cartridge brass, hardness 62 7 Rockwell 30T, or other material of equivalent hardness.
