What is the national standard for connectors? How to choose the right connector?

Connector is a component widely used in electronic equipment and industrial equipment for connecting and disconnecting electrical signals and power. In order to ensure the interchangeability, reliability and safety of connectors between different devices, many countries and regions have issued relevant national standards for connectors. In China, national standards are mainly formulated and issued by the National Standards Committee and the Standardization Technical Committee of various industries. The national standards for connectors include: 1. GB/T 6098.1-2008 General Specifications for Electronic Components and Connectors specifies the general requirements and test methods for connectors, including the type, size, contact resistance, voltage resistance, heat resistance, water resistance, corrosion resistance, etc. The standard applies to all types of connectors. 2. GB/T 5095-2014 Fasteners, Threaded Joints and Connectors for Mechanical Engineering specifies the types, dimensions, materials, mechanical properties, heat treatment requirements and test methods of connectors for mechanical engineering. 3. GB/T 15116. 1-2017 "Automotive Electronic System Connectors. General Principles" This standard specifies the general requirements, terms, definitions, classifications, specifications, quality, testing, etc. Of automotive electronic system connectors. 4. GB/T 2408-2018 Circular Multi-core Cable Plug and Socket System for Connectors-General Specifications This standard specifies the general specifications for circular multi-core cable plug and socket systems for connectors, including dimensions, contact resistance, voltage resistance, heat resistance, corrosion resistance, etc. When selecting a connector, you should first understand the electrical and mechanical requirements required to determine the type and specification of connector required. Then, according to the application scenarios and environmental requirements, select the connectors that meet the relevant national and industrial standards. In addition, attention should be paid to the brand of the connector, the reputation of the manufacturer and supplier, and the quality control system. Proper connector selection can help ensure the performance, reliability, and safety of electronic and industrial equipment and reduce the risk of equipment failure and damage.
