29、TECHNICAL COMMISSION _ CONNECTORS FOR ELECTRONIC EQUIPMENT Part 7: Detail specification for 8-way, unshielded, free and fixed connectors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees

30、 (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Repo

31、rts, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and n

32、on-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements

33、of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are

34、 accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote inter

35、national uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in t

36、he latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or

37、 its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expens

38、es arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attent

39、ion is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60603-7 has been prepared by subcommittee 48B: Connectors, of IEC technic

40、al committee 48: Electromechanical components and mechanical structures for electronic equipment. This third edition cancels and replaces the second edition published in 1996 and constitutes a technical revision. This edition includes the following significant technical change with respect to the pr

41、evious edition: Drawings and test schedules were updated based on the work done developing IEC 60603-7-4. A corrected figure (Figure 10) illustrating a connector de-rating curve has been prepared and inserted in the text. Annex D contains the dimensions that define the panel mounting features on the

42、 connector and panel that were referenced as the Type A, variant 03 connector in the previous edition. 6 60603-7 IEC:2008 The text of this standard is based on the following documents: FDIS Report on voting 48B/1883A/FDIS 48B/1917/RVD Full information on the voting for the approval of this standard

43、can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 60603-7 series, under the general title: Connectors for electronic equipment, can be found on the IEC website. The commit

44、tee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revis

45、ed edition, or amended. 60603-7 IEC:2008 7 INTRODUCTION IEC 60603-7 is the base specification of the whole series. Subsequent specifications do not duplicate information given in the base document, but list only additional requirements. For complete specification regarding a component of a higher nu

46、mber document all lower numbered documents must be considered as well. The following diagram shows the interrelation of the documents: It should be noted that during the preparation of the third edition of IEC 60603-7, the subcommittee 48B Cat 6 therefore, the creepage and clearance distances in IEC

47、 60664-1 are reduced and covered by overall performance requirements. The creepage and clearance distances are given as operating characteristics of mated connectors. In practice, reductions in creepage or clearance distances may occur due to the conductive pattern of the printed board or the wiring

48、 used, and shall duly be taken into account.
