AI Technical Summary
When a traditional wedge clamp holds a conductor, the rigid wedge block makes a fixed contact with the conductor, resulting in an extremely uneven distribution of clamping pressure. This creates extremely high local pressure, causing harmful local stress concentrations that affect the mechanical properties and long-term safety of the conductor.
The anti-loosening tension clamp is adopted. By setting reinforcement parts and separation plates in the positioning shell, and using the rotational connection between the two inclined pressure plates and the clamping plate, adaptive clamping is achieved, improving the distribution of contact pressure. Through the cooperation of the separation plate and spring, preload and self-locking anti-loosening capability are provided to ensure clamping stability.
It improves the contact pressure distribution of the conductor, reduces local stress concentration, reduces the risk of strand damage, ensures the mechanical properties and long-term safety of the conductor, and reduces the entry of external contaminants, thus avoiding clamping instability.
