21、SSION _ CONNECTORS FOR ELECTRONIC EQUIPMENT Part 3-110: Detail specification for 8 way connectors for frequencies up to 600 MHz FOREWORD A PAS is a technical specification not fulfilling the requirements for a standard, but made available to the public. IEC-PAS 61076-3-110 has been processed by subc
22、ommittee 48B: Connectors, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. The text of this PAS is based on the following document: This PAS was approved for publication by the P-members of the committee concerned as indicated in the fol
23、lowing document: Draft PASReport on voting 48B/1115/PAS48B/1153/RVD Following publication of this PAS, the technical committee or subcommittee concerned will investigate the possibility of transforming the PAS into an International Standard. 1)The IEC (International Electrotechnical Commission) is a
24、 worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition t
25、o other activities, the IEC publishes International Standards. 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 wit
26、h the IEC also participate in this preparation. The 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 the IEC on technical matters express
27、, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3)The documents produced have the form of recommendations for international use and are published in the form of standard
28、s, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4)In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their natio
29、nal and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in co
30、nformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. Copyright 2002, IEC 7 CONNECTORS FOR ELECTRO
31、NIC EQUIPMENT Part 3-110: Detail specification for 8 way connectors for frequencies up to 600 MHz 1 Scope This part of IEC 61076-3 covers 8-way connectors up to 4 pairs to be used up to 600 MHz, when used with an appropriate cable. These cables are specified in the IEC 61156 series and used in cabli
32、ng systems specified in ISO/IEC 11801. The connectors are compatible with the already defined IEC 60603-7-7 connectors.1 The connectors are interoperable with the already defined IEC 60603-7-7 connectors.2 1.1 Normative references The following normative documents contain provisions which, through r
33、eference in this text, constitute provisions of this part of IEC 61076-3. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IEC 61076-3 are encouraged to investigate the possibility of applyin
