61076-2-001 © IEC:2001– 7 –INTERNATIONAL ELECTROTECHNICAL COMMISSION___________CONNECTORS FOR ELECTRONIC EQUIPMENT –Part 2-001: Circular connectors –Blank detail specificationFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61076-2-001 has been prepared by subcommittee 48B: Connectors,of IEC technical committee 48: Electromechanical components and mechanical structures forelectronic equipment.The text of this standard is based on the following documents:FDISReport on Voting48B/1085/FDIS48B/1116/RVDFull information for the approval of this standard can be found in the report on voting indicatedin the above table.Future standards in this series will carry the new general title as cited above. Titles of existingstandards in this series will be updated when a new edition is prepared.This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.Annex A forms an integral part of this specification.The QC number that appears on the front cover of this publication is the specification numberof the IEC Quality Assessment System for Electronic Components (IECQ).

61076-2-001 © IEC:2001– 9 –It should be used in conjunction with the applicable sectional specification, see 1.1 of IEC 61076-2.The committee has decided that the contents of this publication will remain unchanged until2002. At this date, the publication will be•reconfirmed;•withdrawn;•replaced by a revised edition, or•amended.

61076-2-001 © IEC:2001– 11 –INTRODUCTIONIn prior years, IEC subcommittee 48B had prepared detail specifications as part of a two-leveldocument system. When the IECQ system was introduced, SC 48B was urged to considerchanging to the four-level specification system as described in IEC Guide 102. This blank detailspecification is part of that four-level document system.This blank detail specification is a supplementary document to the sectional specificationIEC 61076-2 and contains requirements for style, lay-out, and the minimum content of detailspecifications.For the scope and definition of this blank detail specification, see 1.2 of IEC 61076-1 and 1.1 ofIEC 61076-2.Detail specifications not complying with these requirements should not be considered as beingin accordance with the IECQ system, and should not be so described.The complete requirements for the circular connectors described herein should correspond tothis blank detail specification and the current issues of IEC 61076-1 and IEC 61076-2.In the preparation of detail specifications, the contents of 1.2.3 of IEC 61076-1 should be takeninto account.NOTE
In order to facilitate the use of this standard, ‘Guidance notes’ are provided on the left page and thematching clause numbers are on the right page. French pages are followed immediately by English pages. The‘Guidance notes’ are provided to aid the specification preparer in writing a more complete and accurate document.They represent the minimum information necessary. The specification preparer is encouraged to add figures oradditional text that will make the requirements clearer to the user.

The preparation ofspecimen, type and size of the cable/wire bundle shall be as specified in 5.1.4.As an alternative, on the current-carrying capacity curve, together with the maximum operatingtemperature, one current value at a given temperature may be stated in the detail specification.Derating values in a tabular form are also permitted, providing a minimum of two points whichinclude the ambient and maximum temperatures, are given.Important values, for example the current at 70 °C shall be shown in a derating graph.4.2.4 Contact resistanceThe detail specification shall state the maximum allowable value of the contact resistancein mΩ. Initial resistance, resistance after testing and resistance including terminations (ifapplicable), shall be given. The connecting points shall be as specified in 5.1.1.4.2.5 Insulation resistanceThe detail specification shall state:a) that the connector shall be mounted to the test panel specified in 3.9.4;b)whether test method A, B or C is applicable;c)the d.c. voltage that shall be applied, contact to contact and contact to test panel;d)the minimum allowable value of insulation resistance, in MΩ, initially and after testing.The information may be presented in the form of a table, which shall be numbered in theappropriate sequence.4.3 Mechanical4.3.1 Mechanical operationThe detail specification shall state:a)the frequency of the operations;b)the speed of the operations;c)the number of mechanical operations;d)any pause time, mated or unmated (deviation from the standard method).If the detail specification contains more than one performance level, to which the number ofmechanical operations is linked, the relationship may be clarified by showing the details in atable.

The force to be applied andthe maximum axial displacement after the force is removed shall be stated in the detailspecification.4.3.4 Polarizing methodTo assess the capability of the polarizing method, if applicable, a test shall be conducted tocheck whether the polarizing method prevents the mismating of incorrectly matched connectorhalves.

The detailspecification shall state to which styles of connectors the test sequence is applicable. Most ofthe test program may not be applicable to connectors without contacts (housings).The necessary number of specimens to perform the entire test sequence shall be given in atabular form.5.1.1 Arrangement for contact resistance measurementThe detail specification shall contain details of the mated connectors describing the points ofconnection for the measurement of contact resistance.5.1.2 Arrangement for dynamic stress testsThe detail specification shall contain details of the method of mounting, dimensions of panels,detai
