Upgrade of Military Standard-Grade Connection Systems, Coordinated Advancement of Domestic Substitution and Supporting Tools

Military-standard electrical connectors are core basic components for electrical interconnection in equipment systems, which directly determine the reliability, safety and maintenance efficiency of equipment. Products including Series I circular electrical connectors of GJB598 and Type I/II/III electrical connectors of GJB599 have gradually realized substitution and supplementation of imported equivalent products by adopting standardized interfaces, environment-resistant structures and reliable contact designs.

Among them, the GJB599 series follows the technical route of the MIL-DTL-38999 series products. Featuring high density, quick connection, vibration resistance and shock resistance, they are widely applied in aviation, aerospace, shipbuilding, weaponry and electronic information equipment fields. The operating instructions and process specifications of matching crimping tools further standardize product installation, maintenance and mass application. The development of military-standard connectors involves not only the upgrading of products themselves, but also the coordinated improvement of interface standards, process tools, testing methods and after-sales service systems.
