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.

Product Features

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.
  • Surface treatment: Silver plating, tin plating and other processes to enhance conductivity and prevent oxidation.

Mechanical strength and wear resistance

Our rivets possess excellent shear strength and hardness, capable of withstanding hundreds of thousands of operations without loosening or deforming.

Precise dimensions and tolerances

Precision cold heading and CNC machining ensure diameter, length, and head shapes are controlled within micron-level tolerances.

Optimized structural design

  • Various types available: solid rivets and semi-hollow rivets.
  • Special head shapes: flat round head, countersunk head, grooved or knurled structures for anti-rotation.

Customized Service Advantages

We understand that every circuit breaker is uniquely designed. Therefore, we offer much more than just products; we provide comprehensive, customized solutions. Our team of engineers works closely with clients from the early design stages to recommend the most suitable materials and riveting solutions based on circuit load and assembly technology.
