used for high speed serial data (HSSDC)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (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 Reports, 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 non-
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 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 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 international 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
the 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 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
expenses 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) Attention 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 61076-3-103 has been prepared by subcommittee 48B: Connectors,
of IEC technical committee 48: Electromechanical components and mechanical structures for
electronic equipment.
The text of this standard is based on the following documents:
FDIS Report on voting
48B/1373/FDIS 48B/1402/RVD
Full information on the voting for the approval of this standard 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.

Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated when a new edition is prepared.
The committee has decided that the contents of this publication will remain unchanged until
2007. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this standard may be issued at a later date.

1.7 Ordering information
For ordering connectors according to this detail specification, the type designation described in
1.6 shall be used.
2 Technical information
2.1 Terminology
2.1.1 Free connector (Plug connector)
A connector for attachment to the free end of the wire or cable. (Used to describe the gender of
the mating side of the connector that penetrates its mate upon mating. This gender is
frequently, but not always, associated with the common terminology “free”. Other terms
commonly used are “male” and “pin connector.)
2.1.2 Fixed connector (Receptacle connector)
A connector for attachment to a rigid surface. (Used to describe the gender of the mating side
of the connector that accepts its mate upon mating. This gender is frequently, but not always,
associated with the common terminology “fixed”. Other terms commonly used are “female” and
“socket” connector.)
2.1.3 Ribbon cable
A copper conductor cable in which the copper conductors are aligned in a flat ribbon.

3.4 Mating Information
The process of mating an HSSDC connector pair should be accomplished in a “free fit” manner
where no excessive mechanical stresses are placed on the connectors during or after the
mating process. The mating process should be considered in the context of the packaging
surrounding the device, and cable harnessing and management after connection is made.
Stresses considered include those transmitted to the mated connector interface: for example,
cable weight, cable harnessing, and interference with enclosure parts.
The positional requirements in Figure 25 are those existing in the fully mated condition.
3.4.1 Mating direction
Reliable electrical contact is ensured when the free and fixed locking latches are fully engaged
as indicated in Figure 25.
