The performance and durability of MCBs heavily depend on the quality of their internal components, particularly specialized rivets. As a leading China supplier and factory, we provide customized production services for high-performance, high-precision rivets tailored for circuit breaker manufacturers. Our commitment is to deliver reliable hardware components, making us your trusted partner in enhancing circuit safety and efficiency.

Product Description

Product Overview

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.

Key Product Features
1. Excellent Conductivity and Low Resistance
  • High-quality materials: T2 copper, high-conductivity copper alloy or copper-clad steel are typically used to ensure smooth current flow and effectively reduce energy consumption.
  • Surface treatment: Silver plating, tin plating and other processes are available to further enhance conductivity and prevent oxidation.
2. Extremely High Mechanical Strength and Wear Resistance

Circuit breakers generate tremendous impact during opening and closing. Our rivets possess excellent shear strength and hardness, capable of withstanding hundreds of thousands of operations without deformation.

3. Precise Dimensions and Geometric Tolerances

Precision cold heading and CNC machining technologies ensure that the diameter, length, and head shape of each rivet are controlled within micron-level tolerances for seamless automated assembly.

4. Optimized Structural Design
  • Available in solid rivets and semi-hollow rivets depending on your circuit breaker structure.
  • Special head shapes (flat round, countersunk) and knurled structures are available to enhance anti-rotation and positioning.
