Product Description

Product Description

This series of circular electrical connectors is engineered to adhere to the stringent requirements of GJB599A GJB598 (MIL-DTL-38999K) I series and features an innovative snap-on quick connection mechanism. Boasting a compact size and lightweight design, these connectors offer high contact density and exceptional EMI/RFI shielding. The carefully crafted anti-tilt plug design ensures reliability. Equipped with both crimping and welding type contacts, the removable crimping contacts and versatile socket installations—including box, wall, front, rear, and nut fastening types—add flexibility. This product showcases unparalleled high-strength vibration resistance, conforming to the GJB1784A standard tail accessory. Uniquely adapted for special tail accessories with Ti Ni alloy memory rings, these connectors securely clamp shielded cables. Available in nine distinct shell sizes, the mating surfaces feature sealed structures and impressive triple-proof performance. Achieving a protection level of IP65, the connectors utilize a sophisticated five-key guiding mechanism and are safeguarded against misplacement with five distinct anti-misplacement key positions. These connectors are widely deployed across military systems, including aviation, aerospace, weaponry, and other electronic equipment systems.

Behaviour of electricity
- Rated operating voltage

work environment	rated operational voltage	(M)rated operational voltage
normal temperature status	600V	500V
Damp-heat condition	600V	500V
Low pressure condition(4.39KPa)	300V	250V

- withstanding voltage

condition	withstand voltage	(M)withstand voltage
sea level	1500V	1300V

- Insulation resistance: Guaranteed to be no less than 3000MΩ, with damp and hot conditions no less than 100MΩ.

Prevent misplug
Ingenious keyways featuring varied angles on the insulator's outer circle allow manufacturers to transpose and assemble according to user needs. This ensures that plugs and sockets with matching specifications will not mistakenly insert into incorrect counterparts, thereby facilitating the proper connection of plugs and sockets with corresponding assembly numbers while preventing the mismatch of different assembly numbers.
