In the field of electrical protection, miniature circuit breakers (MCBs) are the core guardians of circuit safety. The stability and reliability of their internal structure rely heavily on seemingly tiny yet crucial connecting components—specialized rivets. We specialize in providing circuit breaker manufacturers with customized production services for high-performance, high-precision rivets, striving to become your most reliable hardware component partner.
Miniature circuit breaker rivets are not standard parts; they are special fasteners used inside circuit breakers to precisely secure key components such as contacts, tripping mechanisms, and connecting plates. Their performance directly affects the circuit breaker's contact resistance, breaking capacity, mechanical life, and even its overall safety. Our custom-made rivets are designed to meet the stringent requirements of this specific scenario.
T2 copper, high-conductivity copper alloy or copper-clad steel are typically used to ensure smooth current flow and effectively reduce energy consumption and temperature rise.
Silver plating and tin plating processes are available to enhance conductivity and prevent oxidation.
Our rivets possess excellent shear strength and hardness, capable of withstanding hundreds of thousands of mechanical operations without loosening or deforming during opening and closing impact.
Precision cold heading and CNC machining ensure diameter, length, and head shape are controlled within micron-level tolerances, essential for automated assembly.
Available in solid and semi-hollow types with special head shapes (flat round, countersunk) or knurled structures to enhance anti-rotation and positioning capabilities.
We understand that every circuit breaker is uniquely designed. We offer comprehensive, customized solutions where our engineers work closely with you from early design stages to recommend suitable materials, processes, and riveting solutions based on your circuit load and structural space.
