Performance Test of 7 Pin Trailer Connector
Contact resistance test: Below 50mΩ, the current transmission loss is minimal. Use Kelvin testing for batch sampling, and take the maximum value of each pogo pin as the evaluation indicator. Satisfy the mixed transmission of high current signals, verified through 500 sets of samples, with a standard deviation of <0.7mΩ.
Plug and unplug life test: Using an automatic plug and unplug machine to simulate actual working conditions, the change in connection resistance after 10,000 cycles does not exceed ±5%. The pass rate of integrity testing for the gold-plated layer of the plunger is 99.8%. Frequent plugging of cars and industrial trailers require this high-performance 7 pin trailer connector.
IP67 level sealing verification: Conduct full end packaging water tightness testing based on EN 60529, simulating rain and water immersion. 100% batch sealing verification, suitable for heavy-duty trailers and outdoor machinery applications for outdoor operations.
Temperature rise test: At room temperature of 25℃, power on the 7 pin trailer connector for 30A and continue for 60 minutes. The thermal imaging device records temperature rise data and is stable at<30 ° C. It is far superior to the average level of <45℃ for conventional trolley connectors and can operate safely for a long time under high loads.
Misalignment anti insertion design verification: Through 12 typical misplacement angle tests, the anti-mistake structure can effectively avoid incorrect connections. The actual misplacement failure rate is 0.1%. All pogo pins are designed with positioning guide slopes and asymmetric limit structures. Avoid the risk of blind insertion on site.
Vibration reliability test: 10-2,000Hz sine frequency sweep, 10g acceleration, lasting for 8 hours. Simulate transportation and use of high seismic freight carriages and road and bridge construction trailers. The 7 pin trailer connector is stable without open circuits or virtual connections, and the measured impedance fluctuation range is <2mΩ.
Salt spray test: No red rust for ≥96 hours. The spray corrosion test was conducted according to ASTM B117 standard, and the pogo pins maintained good conductivity. The gold plating layer thickness of the Spring loaded pin is ≥0.5μm, and the performance is stable in coastal, rainy, snowy, and winter salt spraying environments.
