Continued from Application Brief of J599 Series Ⅰ, Ⅱ, Ⅲ in Automotive Industry (Part 1)
J599 Series Ⅲ: Core Task Bearer Under Extreme Environments
Core Features
- Three-start self-locking threaded connection: Boasts the strongest vibration and shock resistance, capable of passing the vibration test of 10Hz~2000Hz, 147m/s².
- High environmental durability: IP67 protection rating, 500-hour salt spray resistance, and an operating temperature range of -55℃~+200℃.
- High-density and mixed-installation capability: Supports 2~61 contact configurations, enabling integrated hybrid transmission of power, signals and optical fibers.
- Electromagnetic shielding: Attenuation ≥ 65dB in the frequency band of 100MHz~10GHz, meeting the requirements of high-precision signal transmission.
Automotive Application Scenarios
1. Battery Management System (BMS) of New Energy Vehicles
Used to connect battery modules and BMS controllers, it is required to transmit high-precision voltage/current data (accuracy ±0.1%) and high-power supply (23A current carrying capacity per contact). Its vibration-resistant design prevents connection loosening of battery packs under complex road conditions, and its temperature resistance adapts to temperature fluctuations during battery charging and discharging.
2. Autonomous Driving Sensor Network
- LiDAR: Supports multi-core optical fiber mixed installation (e.g., 2 optical + 4 electrical contacts), with a transmission rate of up to 10Gbps to ensure real-time transmission of point cloud data.
- Cameras and Millimeter-wave Radars: Provides high-bandwidth signal channels (50Ω impedance per contact), and its anti-electromagnetic interference capability can withstand radio frequency interference (100V/m field strength) from vehicle-mounted radars.
3. Vehicle-mounted High-speed Communication System
Used to connect domain controllers, 5G T-Box and other devices, it supports in-vehicle Ethernet (1000BASE-T1) transmission with a bit error rate of less than 10-9.
4. Powertrain Core Components
Connected to high-voltage components such as motor controllers and inverters, its high-voltage insulation performance (≥5000MΩ@500V DC) and large current carrying capacity (23A for #12 contacts) meet the requirements of 800V high-voltage platforms.
Technical Trends and Innovative Applications
Optoelectronic Hybrid Integration Technology
J599 Series Ⅲ supports hybrid transmission of optical fibers, power and signals. For example, the J599E8 series expanded-beam Fiber Optic Connectors improve the vibration-resistant service life to 1,500 mating cycles through non-contact optical path design, and have been applied to vehicle-mounted LiDAR and avionics equipment.
Material and Process Upgrades
Adopting 316L stainless steel shell and ceramic pins, it can withstand nuclear radiation (10⁶ Gy) and deep-sea high pressure (10MPa). In the future, it is expected to be extended to extreme environment monitoring equipment in intelligent cockpits.
Standardization and Compatibility
The interface of Series Ⅲ is compatible with the MIL-DTL-38999Ⅲ standard, enabling interchangeability with equipment in aviation, naval vessels and other fields, and promoting cross-industry technology reuse.
Conclusion
With its modular design and hierarchical performance, J599 series connectors cover the full-scenario needs of automobiles, from basic electronics to core power systems. Series Ⅰ is characterized by low cost and convenience; SeriesⅡ optimizes space layout through compact and lightweight design; Series Ⅲ supports core tasks of intelligent electrification with ultimate reliability. As automotive electronics moves towards high integration and high reliability, the optoelectronic hybrid integration and extreme environment adaptability of Series Ⅲ will become the key areas of future technological innovation.
