Screw Connector Block
Products Description
The Screw Connector Block employs a classic mechanical clamping structure, consisting of screws, conductive copper components, an insulating body, and a fixing structure. Mechanical force is transmitted through the screws, ensuring tight contact between the wire and the copper conductive component, forming a low-impedance, safe, and stable electrical connection.
Core structural features include:
Screw Clamping Structure: Standardized Clamp Screws apply uniform pressure, firmly clamping the wire, ensuring high reliability and allowing for repeated assembly and disassembly.
High-Quality Copper Conductive Components: The conductive grooves are precision-machined, resulting in a large contact area, low impedance, and minimal temperature rise.
Flame-Retardant Insulating Shell: Utilizing engineering-grade PA66, PC, or composite flame-retardant materials, improving heat resistance, impact resistance, and structural stability.
Modular Structure Design: Allows for a flexible combination of poles according to project requirements, facilitating layout within control cabinets.
Wide Range of Wire Diameter Compatibility: Adaptable to flexible wires, single-strand wires, and multi-strand wires, meeting wiring needs in various scenarios.
Structural Innovation for Constant Pressure
| Pressure Self-Compensation Architecture | A unique combination of disc springs and Stamping Screw Terminal Block stores precise mechanical potential energy during tightening. When the wire undergoes minor deformation due to thermal expansion and contraction or creep, the spring system automatically releases the stored energy, achieving dynamic compensation of contact pressure. This intelligent compensation mechanism ensures that the connection point maintains constant contact pressure throughout its entire lifespan, eliminating the overheating risk caused by pressure relaxation in traditional connections. |
| Three-Dimensional Force Flow Guiding Design | The conductive path inside the junction box is precisely optimized through mechanical simulation. Wire Connector Electric Terminal Block pressure, through a specially designed force flow guiding structure, forms a uniform three-dimensional pressure distribution on the wire contact surface. This pressure distribution pattern ensures that the entire contact surface of the wire participates in conductivity, eliminating fretting wear caused by localized stress concentration, and improving the long-term stability of the connection resistance by an order of magnitude. |
