  Core Principle: Excessive Contact Resistance Terminal overheating is fundamentally caused by abnormally high contact resistance. According to Joule’s law, high resistance generates massive heat when current passes through. Once the terminal contact surface fails to fit tightly, resistance rises sharply, forming a vicious cycle: heat accumulation → increased resistance → more...

Main Causes of Terminal Overheating and Blackening 1. Unqualified Contact & Loose Installation Loose crimping, uneven torque and assembly gaps reduce the effective contact area of terminals. Based on the I²R heating principle, local high resistance generates intense heat, scorching metal surfaces and forming permanent black carbonized marks. Excessive crimping also causes micro-cracks and...

Key Precision Influences of High-Speed Terminal Stamping High-speed stamping usually runs at 1000–6000 strokes per minute. The core precision deviations mainly come from dynamic operation rather than the process itself:   - Equipment Vibration & Position Deviation: Long-term high-frequency impact causes slight body vibration and slider deflection, resulting in step distance errors a...
