Circuit Breaker Terminal
Products Description
Circuit Breaker Terminals, as indispensable connection components in electrical control systems, play a crucial role in industrial automation, power distribution, and equipment manufacturing. Since 1990, we have specialized in silver contacts, contact riveting, contact welding, and metal stamping processes, accumulating over thirty years of professional technical experience. We focus on providing high-quality connection solutions for electrical components such as relays, switches, contactors, and circuit breakers.
Superior Electrical Performance
High Conductivity Materials
The conductive components are made of high-quality electrolytic copper or copper alloy. Some surfaces are plated with silver or tin, significantly reducing contact resistance, enhancing current-carrying capacity, and minimizing energy consumption and heat generation.
Reliable Insulation Protection
The Screw-on Terminal's insulating shell is made of PC material, possessing excellent dielectric strength and arc resistance, effectively preventing safety hazards such as leakage and short circuits.
Constant Contact Pressure
The screw crimping structure of the Fuse Terminal Block provides sustained and balanced contact pressure through precisely designed torque control, preventing loosening due to vibration or thermal expansion and contraction, ensuring long-term power supply stability.
Wide Range of Applicable Wire Diameters
The M5 Electrical Crimping Frame product design is compatible with various wire cross-sectional areas, meeting the connection requirements of different current ratings and flexibly adapting to various electrical systems.
Metal Body Forming Stage
Cold Forging Process
A multi-station cold heading machine is used to sequentially complete the stamping, bending, and drilling processes of the Screw on Terminals clamp body. The processing error at each station is controlled within ±0.05mm to ensure the dimensional accuracy of the clamp.
Wire Clamp Spring Machining
The springs inside the clamp are machined separately. After stamping, they undergo aging treatment to improve the elasticity and fatigue strength of the springs, ensuring the long-term stable preload of the M5 Electrical Crimping Frame.
Spring Assembly and Adjustment
The springs are embedded in the cold-forged wire clamp body. A specialized fixture is used to adjust the spring preload, ensuring stable contact pressure after the wire is connected.
Full Inspection of Body Dimensions
The formed metal body undergoes a full inspection, including the clamp opening size, screw hole position accuracy, and mounting foot size. Non-standard Wire Frames that do not meet the requirements are directly rejected.
