English copy

High-current DC connections must carry power without creating unacceptable heat, voltage loss, or long-term reliability risk. Current rating alone is not enough to approve a connector.

Define continuous current, peak current, voltage, duty cycle, ambient temperature, cable size, enclosure, and cooling conditions. For selected Dajiang power models, product information describes contact resistance below 10 mΩ and standard current support in the 2–8 A range, with customized models available up to 15 A. Confirm the exact rating through a model-specific test report.

Run a representative load test using the final connector, wire, housing, and installation method. Measure temperature rise, voltage drop, and contact stability under the intended load and duration.

FAQ

Question	Answer
Does a higher current rating always mean a better connector?	No. The rating must match the complete system and its thermal conditions.
How can overheating be reduced?	Control contact resistance, mating quality, conductor size, contact force, and thermal conditions.
Can high-current models be customized?	Customized terminal geometry, dimensions, materials, and plating can be reviewed.
