AI Technical Summary
Existing crimp-free plug-in terminals suffer from long-term problems such as failure of elastic elements, uncertainty of contact impedance, and short circuit and electric shock risks caused by the scattering of multiple conductors. In addition, they are complicated to operate and cannot meet the reliability and convenience requirements of applications such as photovoltaic power generation, energy storage and electric vehicle charging.
The terminal body, insulating guide tube, and clamping spring are functionally decoupled. Through the staggered clamping layout of the biting hooks and the pressing part, combined with the formed port of the insulating guide tube and the stop ring surface, the stable clamping and electrical connection of multi-strand core wires are achieved, avoiding direct contact between the elastic element and the terminal body and simplifying the operation process.
It improves the reliability and stability of wiring, reduces contact resistance and short-circuit risk, simplifies the wiring process, adapts to long-term reliability in outdoor exposed conditions, and reduces manufacturing costs and operational complexity.
