Performance Test of 8 Pin Power Connector
Contact resistance stability verification: Measure the resistance change of each pogo pin of the 8 pin power connector using the 4-wire method. The initial contact resistance is 50mΩ, which remains <55mΩ after 10,000 cycles and fluctuates within ± 5mΩ.
Current carrying performance limit test: Apply a constant current of 50A to a single pogo pin at room temperature of 25°C. The temperature rise measured within 30 minutes is controlled within 29.6°C. No melting, annealing or PIN elasticity attenuation.
High voltage withstand test: Apply 1,500V DC voltage to the housing and adjacent pins on all pogo pins for 60 seconds. Leakage current <1μA, safe isolation under high voltage in industrial control systems.
IP67 protection level verification: Soak the 8 pin power connector in a water depth of 1.00m for 30 minutes, then mate it to test its electrical performance again. Contact resistance change <1mΩ, no signs of water ingress. The protection level meets the requirements of IEC standard IP67.
Insertion error prevention tolerance detection: The 8-Pin design has a physical error prevention positioning structure, and any non design direction insertion will automatically reject the connection. Prevent the risk of misconnection and incorrect power on, blind insertion or non line of sight automation applications.
Simulate vibration disengagement test between UAV and mobile terminal: Run for 1 hour under X/Y/Z 3-axis 50Hz sine vibration and peak acceleration of 5g. Continuous power supply without interruption, and pogo pins have not undergone significant deformation or slippage.
Accelerated test of working life: temperature variation of -40℃~85℃, 1,000 cycles of high and low temperature testing of 8 pin power connector. Use X-ray + pogo pin spring force + contact resistance for joint evaluation. Maintain a connection integrity of over 99.9% for use in extreme temperature zones.
High humidity and high salt corrosion testing in industrial and marine scenarios: ASTM B117 standard conducts 96 hour neutral salt spray test with 8 pin power connector. After testing, no green rust was found, the elasticity of the pogo pin was normal, and the resistance fluctuation of the pogo pin was within ± 1.5mΩ.
