9、on 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 to other activities, t
10、he 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 with the IEC also partic
11、ipate 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, as nearly as possi
12、ble, 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 standards, technical specif
13、ications, 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 national and regional s
14、tandards. 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 conformity with one
15、 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. International Standard IEC 60313 has been prepared by IEC tec

BSIEC60313:200226130 3 EI:C0022 5 INTRODUCTION The use of a limited selection of connectors has the advantage of facilitating compatibility between instruments and minimizing the types of connecting cable assembl
19、ies required. This edition of IEC 60313 recommends a limited family of preferred standard coaxial connectors for nuclear laboratory instruments. It includes a medium size, a miniature and a sub- miniature connector to accommodate a range of applications for use with peak voltages not exceeding 500 V
20、. Also included is a small high-voltage connector for voltages up to 5 kV. BSIEC60313:200236130 3 EI:C0022 7 COAXIAL CONNECTORS USED IN NUCLEAR LABORATORY INSTRUMENTATION 1 Scope and object This International Standard applies to coaxial connectors for electrical instruments used in nuclear laborator
21、ies. While particularly useful in such applications, the connectors included in this standard are also useful in other applications. However, this standard does not necessarily apply to nuclear power installations where special requirements may necessitate the use of other connectors, some of which
22、(e.g. types N and TNC) are described in various parts of IEC 60169. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced doc
23、ument (including any amendments) applies.

25、29:1982, Multiple controllers in a CAMAC crate 3 Recommended connectors To comply with this standard, nuclear laboratory instruments shall use the connectors listed below for nuclear signal applications. 3.1 Connectors for peak voltages not exceeding 500 V For applications in nuclear laboratory inst
26、ruments, the following connectors should be used for peak voltages not exceeding 500 V: a) type BNC as defined in IEC 60169-8; b) type 50CM as defined in IEC 60729; c) type SMB as defined in IEC 60169-10. BSIEC60313:200246130 3 EI:C0022 9 3.2 High-voltage connector For applications up to 5 kV, type
27、B connectors, as defined in IEC 60498, should be used. These connectors are often termed type SHV connectors (Safe High Voltage). See also 4.3. 4 Descriptions 4.1 BNC connector The BNC connector (3.1a) is a medium size connector that has been in use for a long period of time and continues to be used
28、 in a wide variety of applications and disciplines. 4.2 50CM and SMB connectors The type 50CM (3.1b) (commonly referred to as the LEMO connector) is a miniature connector with a positive securing mechanism while the type SMB (3.1c) is a subminiature snap-on connector. As technology advanced, particu
29、larly with the advent of solid-state circuitry, instrument panel space became both scarce and crowded while the number of input and output connectors continued to increase. Thus, the miniature type 50CM connector (3.1b) and the subminiature type SMB connector (3.1c) came into common use on NIM (see
30、1 1 ), CAMAC (see IEC 60729 and 2) and Fastbus (see 3) instruments as well as in numerous other applications, both in nuclear instrumentation and in many other areas. 4.3 High-voltage connector The high-voltage connector (3.2) is commonly known as type SHV (Safe High Voltage) connector. It is a smal
31、l connector in which the pin and socket contacts are recessed within the con- nector housing and surrounded by insulating sleeves so as to minimize the possibility of the user accidentally coming into contact with high voltage when the connector pair is not mated. _ 1Figures in square brackets refer
