[0028] 1. Adapting to conductor expansion: The T-shaped structure of the clamping plate 2, together with the movable rod 5 and the compression spring 8, allows the clamping plate 2 to slide along the movable rod 5 when the conductor expands due to heat. The compression spring 8 provides elastic support, ensuring that the connection parts are always tightly fitted, preventing the connection from loosening or failing due to expansion.

[0029] 2. Reduce contact resistance: The contact end of the clamping plate 2 is in direct contact with the conductor. The T-shaped structure design increases the contact area. At the same time, the cooperation of the blocking plate 7 and the compression spring 8 ensures stable pressure at the contact end, effectively reducing contact resistance and reducing the risk of overheating.

[0030] 3. High-efficiency heat dissipation performance: The heat dissipation fins 4 are fitted onto the outer ring of the connecting ring 1 and fixedly connected to the fixed end 6, forming a good heat conduction path. The clamping plate 2, the movable rod 5, and the fixed end 6 are made of metal materials with good thermal conductivity, which further enhances the heat dissipation effect and ensures stable operation of the connection parts in high-temperature environments.

[0031] 4. Enhanced Mechanical Strength: The combined design of the positioning plate 3 and the connecting ring 9 provides additional mechanical support, ensuring the stability of the connection structure under external forces. The cooperation of the locking rod 10 and the locking nut 11 further enhances the robustness of the connection.

[0032] 5. High temperature resistance: The entire structure is made of high temperature resistant materials and optimized design to ensure long-term reliability in high temperature environments, making it particularly suitable for electrical connection scenarios with high temperature and high current density.

[0033] In summary, this device, through innovative structural design and material selection, effectively solves the problems of high contact resistance, poor expansion adaptability, and insufficient heat dissipation performance in existing technologies, and significantly improves the conductor connection performance of insulated high-temperature resistant wires and cables.
