What international or domestic industry standards do military electrical connectors need to comply with?

Military electrical connectors need to comply with a series of international and domestic industry standards to ensure their reliability and performance in harsh environments. Here are some common standards and their specific requirements:

International Standards
MIL-DTL-38999
Definition: A military circular connector standard developed by the U.S. Department of Defense for high-density, environment-resistant electrical connectors in the aerospace and defense fields.

Requirements:
Mechanical properties: including vibration resistance (up to 50 g), shock resistance (300 g, 3 ms) and high plugging and unplugging times (more than 500 times).
Environmental adaptability: extreme temperature resistance (-65°C to +200°C), salt spray resistance (up to 2000 hours), chemical corrosion resistance (such as hydraulic oil, aviation fuel, etc.).
Electrical performance: shielding effect is greater than 90 dB at 100 MHz and greater than 65 dB at 10 GHz.
Structure: Provide a variety of coupling methods (such as threaded, bayonet, bolt-on) and shell materials (such as aluminum alloy, stainless steel, composite materials).

MIL-STD-810
Definition: US military standard used to test the reliability of equipment under various environmental conditions.
Requirements:
Including temperature, humidity, vibration, shock, sand and dust, salt spray and other environmental tests.
This standard emphasizes customizing the test plan according to the actual use environment of the equipment, rather than simple environmental simulation.

IEC Standard
IEC 60068 series: Environmental test standards, which specify the test methods for connectors under conditions such as temperature, humidity, and salt spray.
IEC 60512 series: Involving the testing of mechanical properties (such as plugging and unplugging force, mechanical life) and electrical properties (such as contact resistance and insulation resistance) of connectors.

Domestic Standard
National Military Standard (GJB)
GJB 150A: my country's military equipment environmental test standard, adapted from the US military standard MIL-STD-810G, covering climate and mechanical environmental testing.
GJB 2889: Circular connector standard applicable to aviation, aerospace and other fields.

Industry standards
my country's electrical connector standards are divided into three levels: national military standards, industry military standards, and enterprise military standards.
High-reliability wire spring structure electrical connector standards: including printed circuit electrical connectors and rectangular electrical connectors, suitable for internal signal transmission of airborne equipment.
