[0021] Furthermore, the elastic contact piece 3 is an arc-shaped phosphor bronze sheet with a silver-plated surface, and its two ends are fixedly mounted on the conductive post 1 by fixing nuts 7.

[0022] In this embodiment, the elastic contact piece 3 is an arc-shaped phosphor bronze piece, whose good elasticity and conductivity ensure stable contact between the terminal and the wire. At the same time, the surface silver plating further improves its conductivity and corrosion resistance.

[0031] Working Principle: During use, the wire is inserted into the wire slot 9, and the movable pressure block 11, under the action of the pressure spring 13, presses the wire tightly, ensuring a stable connection. Simultaneously, the arc-shaped design and good elasticity of the elastic contact piece 3 ensure a tight contact between the wire and the terminal, reducing contact resistance and heat generation. The double-nut structure of the anti-loosening nut 4 and the design of the compression spring 6 effectively prevent the nut from loosening under long-term vibration or high-current loads, ensuring the stability and safety of the terminal. The insulating fixing base 2 is made of polyphenylene sulfide (PPS) material, which has excellent insulation and high-temperature resistance, effectively preventing insulation failure of the terminal in high-temperature and high-humidity environments.
