IEC 61169-71:2022

Overview

IEC 61169-71:2022 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the sectional requirements for RF coaxial connectors with an inner diameter of the outer conductor of 5.0 mm and a characteristic impedance of 50 Ohms, specifically the type NEX10®. This standard serves as a guideline for the preparation of detailed specifications used in designing and manufacturing these connectors primarily for use in 50 Ω radio communication systems.

The document covers critical aspects such as mating face dimensions, gauging information, and testing procedures and requirements, providing a comprehensive framework that ensures interchangeability, reliable performance, and quality assessment of RF connectors within the NEX10® series. It caters to connectors operating at frequencies up to 20 GHz, making it particularly relevant for modern radio frequency transmission systems involving RF cables and microstrip circuits.

Key Topics

• Connector Specifications:
  IEC 61169-71:2022 outlines detailed mating face dimensions for general-purpose connectors (Grade 2), including screw type connectors with pin center contacts, quick lock types, and connectors with socket center contacts.

• Gauging and Testing:
  The standard specifies gauge pins and rings, facilitating precision measurement and verification of connector dimensions, ensuring compliance with interface requirements. It adopts test procedures and selected tests from IEC 61169-1, particularly focusing on acceptance and periodic testing which are essential for quality assurance.

• Performance Characteristics:
  Recommended performance parameters are detailed for use when drafting detailed specifications, emphasizing parameters such as electrical, mechanical, and environmental performance to meet high reliability needs.

• Quality Assessment:
  A comprehensive quality conformance framework is included, covering inspection requirements for different assessment levels (M and H), qualification approval processes, and schedules for routine acceptance and periodic testing to maintain connector integrity over time.

• Detailed Specification Guidelines:
  The standard provides instructions for preparing detailed specifications, including identification, marking, ordering information, test selections, and test severities, supporting manufacturers in aligning product development with international benchmarks.
