Real-World Application Cases

1. RV Energy Storage Power System Project

A US-based RV OEM purchased Yiqi Heavy Duty Ring Terminal Vibration-resistant Circuit Connectors in bulk for use in off-grid RV energy storage systems. RVs frequently encounter bumpy roads and stop-and-go driving, conditions that easily cause battery and inverter wiring to loosen. The product’s ring-locking structure securely fastens cable terminals; during long-distance off-road travel and high-frequency vibration testing, the circuit between the energy storage power supply and the inverter maintained efficient conductivity, eliminating power interruptions to onboard appliances. Additionally, its compact design fits into the cramped electrical compartments of RVs, effectively saving installation space and improving assembly efficiency.

2. Industrial Inverter Power Distribution Project

An industrial engineering firm in Southeast Asia utilized Yiqi RT-02 connectors in their workshop's inverter power distribution system. Industrial equipment often operates continuously for long periods, where mechanical vibration can easily cause standard terminals to loosen and overheat. By adopting these vibration-resistant terminals, the workshop's high-current power distribution system achieved stable year-round operation, free from issues like abnormal heat generation or poor contact. The product's fast-acting characteristics provide effective overcurrent protection for industrial equipment, significantly lowering maintenance costs and reducing losses associated with downtime.
