In the field of avionics, Soulin’s GX aviation connector achieves outstanding power transmission through a precise contact design. Its single-pin rated current can reach 23 amperes, it can withstand a voltage of 600 volts, and the contact resistance is stable below 2.5 milliohms. It adopts a copper alloy gold-plated contact structure with a coating thickness of 0.76 microns, ensuring that the electrical conductivity does not decline by more than 5% after 10,000 insertion and extraction cycles. For instance, during the avionics system test of the domestically produced C919 passenger aircraft, the temperature rise of similar connectors was controlled within 25°C under 2,000 hours of continuous load, and the power transmission efficiency was maintained at a high level of 98.5%.
Innovation in materials science is the cornerstone of reliability. The GX aviation connector housing is made of composite reinforced polymer, with a flame retardant rating reaching UL94 V-0 standard, maintaining mechanical strength in an environment ranging from -55°C to 175°C. The dielectric strength of the internal insulator is as high as 1000 volts per millisecond, and the leakage current is less than 10 microamperes. This characteristic enables the equipment to operate stably in a low-voltage environment at cruising altitude (approximately 10,000 meters). Referring to the research on the power supply network of the Boeing 787, the optimized aviation connector reduces power loss by 3%, saving approximately $12,000 in fuel costs per aircraft annually.
In terms of mechanical structure, the triple locking mechanism can withstand an impact vibration of 50G. The insertion force is precisely controlled within the range of 35-60 Newtons, and the separation force deviation does not exceed ±5%. In the actual measurement of the military aircraft avionics platform, this design enables the impedance fluctuation of the connector to be less than 1% in the random vibration environment of 20-2000Hz, fully conforming to the DO-160G aviation standard. As pointed out in the 2023 Aerospace Industry report, the satellite payload system adopting the enhanced GX aviation connector has reduced its in-orbit failure rate to 0.001 times per thousand hours and extended its lifespan to 15 years.
Environmental adaptability test data shows that after the 48-hour salt spray corrosion test, the contact impedance change rate of the GX series products is less than 3%, and the insulation resistance remains at 10^12 ohms in an environment with a relative humidity of 95%. This stability has enabled a certain drone manufacturer to reduce the signal interruption probability from 10^-5 to 10^-7, and at the same time extend the maintenance cycle from 500 hours to 2000 hours. Industry data shows that systems using high-reliability aviation connectors can reduce the full life cycle cost by 18%, which confirms the strategic value of Soulin’s continuous investment of 8% of its annual R&D budget in the field of connection technology.
