Cage Terminal Mechanical Parts
Products Description
The Cage Terminal Mechanical Parts utilizes a design concept that combines screw-based clamping with a cage-spring structure, allowing for direct integration into electrical equipment as a pre-assembled unit. Users insert the wire into the terminal opening and tighten the screw to establish a secure connection, eliminating the need for additional accessories or complex tools. Functioning as an electromechanical interface component, it provides both mechanical fastening and electrical conductivity, ensuring low contact resistance and high reliability even under conditions of vibration, thermal expansion/contraction, or prolonged loading.
Compared to traditional exposed terminals, the Cage Terminal's pre-assembled nature significantly enhances assembly efficiency and consistency. Its cage structure exerts automatic clamping force, maintaining contact pressure on the wire even if the screw loosens slightly; this effectively prevents issues such as loosening and overheating, thereby meeting the rigorous safety, convenience, and durability standards required by modern electrical equipment.
Advanced Material Advantages
| Cage Matrix | For standard power distribution units and wall switches, we utilize high-rigidity, fatigue-resistant premium brass or precision copper alloys, balancing excellent electrical conductivity with high tensile strength. For extreme operating conditions-such as those involving photovoltaic fuses and high-capacity circuit breakers-we offer solutions using specialized cold-rolled steel, stainless steel, or high-hardness alloy steel, ensuring the cage structure undergoes no yielding or deformation during high-torque closure. |
| High-Tensile Fastening Screws | Our Circuit Breaker Terminals matching screws are manufactured from high-strength alloys, featuring superior thread precision and exceptional tensile and shear strength ratings. This effectively prevents issues such as stripped threads, head breakage, or thread failure during tightening with high-frequency or high-torque power tools. |
| Low-Contact-Resistance Coatings | Components feature advanced composite plating processes (such as overall thick matte nickel plating, electroless tin plating, or selective silver plating). These coatings offer outstanding corrosion and salt-spray resistance, maintaining extremely low contact resistance and robust oxidation resistance even in challenging new energy environments characterized by high humidity, sulfur exposure, or salt-laden air. |
Key Function: Ensuring the Dynamic Stability of Electrical Connections
Dynamic Clamping and Anti-Loosening
Over years or even decades of operation, thermal cycling and system vibrations cause conductors to undergo thermal expansion, contraction, and stress relaxation. Through a specialized mechanical design, the Clamp-Type Screw Terminal for Circuit Components provides a continuous, adaptive clamping force that compensates for conductor deformation, thereby preventing connection loosening.
Creation of a Large-Area Electrical Contact Network
Unlike Steel Cage Screw Terminal Blocks that rely on point contact, the clamp structure causes the conductor to deform slightly and conform to the clamp body during tightening. This establishes a surface-to-surface or multi-point line contact network, significantly reducing contact resistance and suppressing temperature rise at the connection point.
Electrodynamic Resistance Barrier
When a molded case circuit breaker (MCCB) encounters a short-circuit fault, the massive short-circuit current generates intense electrodynamic repulsive forces. The high-strength mechanical structure of the clamp effectively withstands these instantaneous forces, preventing the conductor from being ejected and ensuring safety during the fault interruption process.
