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 61076-4-111 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/1123/FDIS48B/1171/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.Annex A forms an integral part of this standard.

61076-4-111  IEC:2002(E)– 7 –71 General dataThis specification contains modular two-part power connectors having a grid of 2,5 mm forprinted boards and backplanes. The described modules are n x 25 mm with n = 1 and n = 2.The required board mounting spacing is 15 mm or more. The standard power contact has afirst make / last break function in respect to the first make / last break signal contact describedin IEC 61076-4-100. The connector is not intended for mating and unmating under heavy load(non-signal).Throughout this specification, all dimensions are in millimetres.1.1 Recommended method of mountingThe free board connector is provided with compliant press-in terminations. The mounting of thefree board connector is achieved by press-in pivots; the terminations of the free boardconnector fit into holes in the printed board according to IEC 60352-5 located on a grid of2,5 mm. Each contact has five press-in sections.The fixed board connector is provided with compliant press-in terminations. The mounting ofthe fixed board connector is achieved by press-in pivots, the terminations of the fixed boardconnector fit into holes in the printed board according to IEC 60352-5 located on a grid of2,5 mm. Each contact has five press-in sections. Care must be taken that the five terminationsare connected to each other by traces adequate to bear the required current on the backplane,for it might be that, on multispring designs, there are no internal connections within theconnector.For the press-in operation, the tooling recommended by the connector supplier should be used.See annex A for guidance on the application of these connectors in mechanical structuresaccording to IEC 60917-1.1.1.1 Number of contactsStyleABNumber of contacts7171.2 Ratings and characteristicsRated voltage:500 V r.m.s. for pollution degree 1 (according to IEC 60664-1, table 4)100 V r.m.s. for pollution degree 2 (according to IEC 60664-1, table 4)Impulse withstand voltage:2 kV for pollution degrees 1 and 2 (according to IEC 60664-1, table 2)Current rating:15 A at 70 °CInsulation resistance:104 MΩClimatic category:PL1: 55/125/56PL2: 55/125/21Printed board:Hole diameter: plated-through hole 0,94 mm to 1,09 mm accordingto IEC 60352-5.Board thickness: 1,4 mm min.Backplane:Hole diameter: plated-through hole 0,94 mm to 1,09 mm accordingto IEC 60352-5.Board thickness: 1,4 mm min.Contact spacing:2,5 mm
