IEC 61169-24:2019 pdf download.Radio-frequency connectors – Part 24: Sectional specification
1 Scope
This part of IEC 61 1 69, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connectors with screw coupling, typically for use in 75 Ω cable networks (type F). It describes the interface dimensions with gauging information and the mandatory tests selected from IEC 61 1 69-1 , applicable to all DS relating to type F connectors. This specification indicates the recommended performance characteristics to be considered when writing a DS and covers test schedules and inspection requirements. NOTE Millimetres are original dimensions. All undimensioned pictorial configurations are for reference purposes only.

4 Interface dimensions
4.1 Dimensions 4.1.1 Connector “F” type female socket (indoor) physical dimensions Figure 1 shows a connector “F” type female socket (indoor).
4.2 Mechanical gauges
4.2.1 Mating socket centre conductor acceptance diameter test In order to verify that the centre female contact of the socket does not suffer from mechanical deformation when mated with the full range of indicated inner conductor diameters, a test has been devised. This test measures the force required to insert and withdraw a selection of precision test pins into and out of the “F” female socket under test. The test apparatus should be so designed as to enable accurate alignment of the “F” female socket under test with the precision test pin. The apparatus should hold either the socket or the test pin in a fixed position, and the moving part of the apparatus should be fitted with an instrument capable of measuring the insertion and withdrawal force. Using the test sequence shown below, the insertion and withdrawal force shall be measured and recorded in newtons. Figure 3 shows a gauge for the centre socket conductor.4.2.2 Mating port centre conductor acceptance electrical test After completion of the mechanical tests described in 4.2.1 , the centre conductor contact resistance, when re-mated with a male “F” plug whose centre conductor diameter is 0,635 mm, shall not exceed 1 0 mΩ with an applied test ampere rate of 1 A. 4.2.3 Reference plane electrical contact The electrical contact shall be made by the mating of the reference plane face of the “F” female socket with the mating face of the “F” male plug and not by the threads alone.
5 Quality assessment procedures
5.1 General The following subclauses provide recommended ratings, performance and test conditions to be considered when writing a detail specification (DS). They also provide an appropriate schedule of tests with minimum levels of conformance inspection. 5.2 Ratings and characteristics The RF connectors defined in this document are designed for use with a variety of flexible and semi-rigid coaxial cables and in microwave integrated circuits and similar uncabled applications. Rating and characteristics are given in Table 4.
