What are the connector industrial standards?

A connector is an industrial component used to connect electrical equipment and is one of the important components in electronic and electrical engineering. In order to ensure the quality, safety, and interchangeability of connectors, countries and international organizations around the world have developed various standards that specify requirements for the design, manufacturing, testing, and certification of connectors. The following will introduce some major connector standards.
1. IEC (International Electrotechnical Commission) standards
IEC stands for International Electrotechnical Commission and is an international electrical standardization organization. IEC has established numerous standards in the field of electrical engineering, including connector standards. The IEC standard mainly specifies the requirements for the size, electrical performance, environmental adaptability, and other aspects of connectors. The IEC standard is one of the globally recognized connector standards, widely used in various fields such as electronics, power, communication, automotive, etc.
2. ISO (International Organization for Standardization) standards
ISO is the abbreviation of the International Organization for Standardization, which is an international standardization organization. ISO has established standards in various fields, including connector standards. The ISO standard mainly specifies the requirements for the size, electrical performance, environmental adaptability, and other aspects of connectors. The ISO standard is also one of the globally recognized connector standards, widely used in various fields.
3. MIL Spec (Military Specifications) standard
MIL Spec is a standard for military connectors in the United States, developed by the Department of Defense to standardize requirements for the design, manufacturing, testing, and certification of military connectors. MIL Spec connectors have very high performance requirements, such as anti vibration, anti-interference, waterproof and dustproof capabilities, and are therefore widely used in military and aerospace fields.
4. EN (European Norm) standard
EN is an abbreviation for European standards, developed by the European Organization for Standardization to standardize requirements for connector design, manufacturing, testing, and certification within Europe. The EN standard mainly specifies the requirements for the size, electrical performance, environmental adaptability, and other aspects of connectors. EN standards are widely used in Europe.
5. JIS (Japanese Industrial Standards) standards
JIS is the abbreviation for Japanese Industrial Standards, developed by the Japan Industrial Standards Organization to standardize requirements for connector design, manufacturing, testing, and certification within Japan.
