9、s sectional specification (SS) was prepared by CECC Working Group22: R.F. Connectors. It is based, wherever possible, on the Publications of the International Electrotechnical Commission and in particular on IEC339-2:1972: General purpose rigid coaxial lines and their associated flange connectors. T

10、his SS and its associated blank detail specifications(s) BDS are specific to the six sizes of EIA FLANGE connectors and their related accessories. The text of this specification was circulated to the CECC for voting in the documents listed below and was ratified by the President of the CECC for prin

11、ting as a CECC specification: Series EIA FLANGE connectors of the types covered by this SS are available in six sizes, each size having a different mating face but employing structurally similar principles of mechanical construction. The connections described are derived from EIA and IEC standards,

12、and include versions for both507 and757 systems.

NOTEA detail specification is a “completed” blank detail specification.EN122150:1993 BSI 04-2000 5 Introduction Although EIA FLANGE connectors were originally

14、intended for use with rigid coaxial air lines only, they are currently available in a number of additional styles and variants, suitable for use with semi-flexible cables having convoluted outer conductors. The outer conductor mating interface is sexless, each half of a mated pair having an identica

15、l coupling flange. Two intermateable versions of the coupling flange are available, fixed and rotatable (swivel type). Connectors with fixed flanges have IEC type designations ending2. Swivel type flange connectors have IEC designations ending in3. With both fixed and swivel type flange connectors,

16、the inner conductor connection is by means of a separate coupling element comprising a double-ended male contact and insulator assembly (Bullet). When the connector is used in conjunction with rigid lines, the Bullet may form the only mechanical support for the centre conductor. The connector sizes

17、relate to the nominal outside diameter of the rigid coaxial transmission line with which they were intended to be used. The size was originally expressed in fractional inches, but the IEC type designation for rigid coaxial lines includes both the nominal characteristic impedance, and the outside dia

18、meter in millimetres rounded to a convenient whole number. SUMMARY OF DIMENSIONS 50 7 Line Size 75 7 Line Size UPPER FREQUENCY LIMITS The upper frequency limit of operation is determined by the cut-off frequency of higher order “waveguide” modes of propagation, and the effect which they have on the

19、impedance and transmission characteristics of the normal TEM coaxial transmission line mode. The lowest cut-off frequency occurs with the TE 11waveguide mode, and this cut-off frequency in an air dielectric line is the upper frequency limit of a practical coaxial transmission line. In general it is

20、not advisable to operate coaxial systems at frequencies greater than95% of the TE 11mode cut-off frequency; this particularly applies in the vicinity of discontinuities such as undercuts and support insulators. The table below lists the recommended upper frequency limits for both straight and right-
