Screw Clamp Connecting Terminal Block
Products Description
The Screw Clamp Connecting Terminal Block is a mechanical crimping terminal assembly. Its core structure consists of three parts:
Conductor contact area: The metal part used to support and stabilize the contact wire;
Screw fastening system: Applying axial pressure to the conductor by tightening the Crimping Frame;
Insulated terminal frame: Positioning, isolating, and protecting the conductor and fasteners.
This structural design achieves rapid wire fixing and repeated assembly/disassembly without relying on specialized crimping tools, balancing engineering efficiency and long-term reliability.
Core Functions: Tailor-made Connection Guarantee for Electrical Equipment
Reliable Conductor Fixation
A Crimping Frame Screw Color Galvanized-locking mechanism securely clamps single/multi-strand conductors (solid/soft wires), preventing conductor detachment due to vibration or temperature changes and ensuring long-term conductivity stability;
01
Electrical Safety Protection
Integrated insulation, flame retardant, and anti-electric shock design blocks conductive contact between conductors and the equipment housing, reducing the risk of short circuits and leakage, and adapting to different voltage levels (AC/DC). Suitable for 12V-690V scenarios;
02
Ready-to-use compatibility
The pre-assembled structure eliminates on-site assembly, allowing direct embedding into pre-reserved interfaces on the equipment, improving production line assembly efficiency and reducing human error.
03
Easy maintenance
Screw Fastener Terminals can be repeatedly disassembled and adjusted, supporting wire replacement or capacity expansion without damaging the equipment structure, reducing later maintenance costs.
04
Multi-wire diameter compatibility
A single model can adapt to multiple wire specifications (0.5-6mm²), reducing the number of specifications to be purchased and simplifying inventory management.

Manufacturing Advantages: Precision is the sole measure of safety
Precision Collaborative Manufacturing of Components
Our Terminal Screw Combinations and conductive frames are collaboratively designed and manufactured under the same quality system. The screw's thread precision and hardness, along with the frame's threaded holes, material strength, and elasticity, undergo countless matching tests to ensure a seamless fit, like a mortise and tenon joint.
Automated Pre-assembly and Inspection
In a cleanroom, automated robotic arms pre-tighten the Clamp Screw for Circuit Breakers, and high-precision torque sensors calibrate the pre-tightening force. Each component undergoes image inspection and torque sampling before leaving the production line to ensure 100% compliance with design specifications.
Rigorous Joint Performance Testing
We test not only individual components but also the entire "screw + frame" system. This includes temperature rise cycle testing, vibration testing, salt spray testing, and short-circuit thermal stability testing to ensure absolute reliability under real-world operating conditions.
Application Advantages: Empowering Critical Electrical Connections
Residential and Commercial Building Electrical Systems
Wall switches, sockets, and distribution boxes experience frequent daily plugging and unplugging or bear long-term loads. Our Clamp Screw for Contactors provide durable and reliable connections, preventing overheating, arcing, and even fire risks caused by poor contact, forming the cornerstone of building electrical safety.
Industrial Control and Automation Equipment
PLCs, circuit breakers, contactors, and motor terminals. These devices have densely packed internal connection points, and the environment may be filled with vibration and electromagnetic interference. Our junction boxes provide high vibration resistance, stable electrical performance, and can withstand repeated wiring adjustments.
New Energy Power Generation Systems (Photovoltaic/Energy Storage)
Clamp Screw for Air Switches in outdoor photovoltaic combiner boxes, inverters, and energy storage battery cabinets. These face severe challenges from diurnal temperature variations, ultraviolet radiation, and humidity condensation. We use special weather-resistant materials and coatings to ensure that connection points remain stable throughout their 25-year lifespan, preventing power generation loss or safety accidents due to connection failures.
Transportation electrification (electric vehicles/charging stations)
On-board chargers, battery management units, and charging gun sockets require high current carrying capacity, extremely high safety levels, and excellent environmental resistance. Our high-conductivity, high-performance Frame Screw Crimp Terminals series is specifically designed for such high-voltage applications.
