High-Performance J30 Series Mini-Rectangular Connectors | China Suppliers & Factory for Military Electronics
Features and Advantages
-
1A core feature of this series is its high-density contact arrangement, available in two standard grid patterns: 1.27mm × 2.54mm and 2.54mm × 2.54mm.
-
2This configuration allows for a significantly high number of signal and power contacts within a compact footprint, directly supporting system miniaturization.
-
3The connectors utilize wire twisting pin (twisted-pin) contacts, a design that provides multiple, redundant points of electrical contact.
-
4This yields key advantages: superior electrical conductivity with low and stable contact resistance, excellent resilience against vibration and shock, and enhanced durability over numerous mating cycles.
-
5The series offers versatility in construction with both metal and plastic shell options.
-
6Metal shells provide robust EMI shielding and maximum mechanical strength, while plastic shells offer a lighter-weight alternative for applications where weight reduction is critical.
-
7This flexibility allows designers to optimize the connector for specific performance, weight, and cost targets without sacrificing the inherent reliability mandated by the GJB2446A standard.
Application
These connectors are widely used for electrical circuit connections in military electronic equipment. Their primary application is in systems where small installation space and light weight are non-negotiable design drivers. This includes:
Man-pack radios, handheld terminals, and surveillance devices.
Onboard mission computers, flight control systems, and sensor pods in aircraft and unmanned aerial vehicles.
Electronics within missiles, smart ordnance, and targeting modules.
Dense electronic suites in armored vehicles, command posts, and other mobile platforms.
Frequently Asked Questions (FAQ)
This series is available in two standard grid patterns: 1.27mm × 2.54mm and 2.54mm × 2.54mm. These options allow engineers to select the appropriate pitch based on space constraints and signal density requirements of their specific application.
Twisted-pin contacts create multiple redundant points of electrical contact, resulting in low and stable contact resistance, superior electrical conductivity, and excellent resistance to vibration and mechanical shock. This design also significantly enhances durability across a high number of mating and unmating cycles.
Choose a metal shell when your application requires robust electromagnetic interference (EMI) shielding and maximum mechanical strength — common in avionics, weapon systems, and harsh military environments. Opt for a plastic shell when minimizing overall system weight is a priority, such as in portable or man-pack equipment.
These connectors are designed and manufactured in compliance with the GJB2446A standard, which is a Chinese military standard governing the performance, reliability, and testing requirements for rectangular electrical connectors used in defense electronics.
Yes. The compact footprint, high contact density, and robust mechanical performance of this connector series make it well-suited for UAV onboard systems, flight control electronics, missile guidance modules, and smart ordnance — all environments where space, weight, and reliability are critical.
Yes. The high-density grid arrangement supports a large number of both signal and power contacts within a single compact connector body. This makes the series highly efficient for mixed-signal applications found in military communication systems, vehicle electronics, and reconnaissance equipment.
