AMP Terminal Screws
Products Description
AMP terminal screws are essentially precision-designed mechanical components used to establish and maintain stable, low-resistance connections in electrical terminals. Their core characteristic lies in their "functional" properties.
Precise Mechanical Converter: They linearly and predictably convert applied torque into a clamping force perpendicular to the wire. This precise conversion is fundamental to ensuring a stable connection and preventing overtightening or loosening.
Reliable Electrical Conductor: Their materials and surface treatments must possess excellent conductivity to avoid introducing additional series resistance and voltage drop in the connection path.
Long-Term Environmental Resistance: They must be able to withstand long-term exposure to vibration, thermal expansion and contraction, and environmental factors such as humidity and corrosive gases, maintaining their designed clamping force.
Core Technical Features: Breaking Through the Performance Limitations of Traditional Screws
Anti-vibration and Anti-loosening Locking Technology
Utilizing a "serrated anti-loosening thread + head knurling design," the thread engagement surface forms a mechanical self-locking mechanism after tightening.
Precision Adaptive Manufacturing Technology
Thread accuracy reaches 6H grade, shank length tolerance ≤ ±0.02mm, head coaxiality ≤ 0.01mm, and the fit gap with the screw terminal screws hole ≤ 0.015mm, ensuring uniform force on the wire during crimping.
Optimized Conductive Contact
The contact area between the terminal block clamp head and the wire adopts a spherical design + conductive coating treatment, effectively increasing the contact area by 30%, stabilizing contact resistance, and avoiding heat and erosion caused by localized current concentration.
Environmentally Resistant Enhancement Technology
The surface uses a multi-layer anti-corrosion coating (zinc-nickel plating, silver plating, etc.), achieving a salt spray test standard of over 96 hours. It exhibits stable performance in a wide temperature range of 40℃ to 150℃, making it suitable for harsh working conditions.
Design Advantages: A Deep Integration of Engineering Aesthetics and Function
Head Optimization
The flat head design facilitates tooling while providing a larger contact area, reducing installation stress.
01
Thread Geometry Optimization
The thread shape is optimized through electromagnetic field simulation to ensure optimal locking force under vibration.
