Product Overview
Miniature circuit breakers come in a wide variety of models and specifications, resulting in significant differences in the size, material, and performance requirements of the rivets. We reject the "one-size-fits-all" standardized production model and instead focus on customer needs, providing comprehensive customization services to ensure a perfect fit between the rivets and the internal structure of the circuit breaker.
📐
Size Customization: Rivet shank diameters range from 0.8mm to 5mm, and lengths from 1mm to 10mm. All sizes can be precisely machined according to customer-provided drawings or samples, with errors controlled within ±0.01mm, effectively avoiding installation jams and loose connections caused by dimensional deviations.
For circuit breakers with special structures, we can also customize different structural types such as stepped rivets, semi-hollow rivets, and solid rivets to meet diverse functional requirements such as conductive connections, insulation fixation, and component fastening.
🔬
Material Selection: We offer a variety of base materials including copper, copper alloy, stainless steel, and iron, with surface treatments such as silver plating, tin plating, and zinc plating. High-purity copper with silver plating increases conductivity by more than 30%; 304 stainless steel options provide superior corrosion resistance for casing fixation.
Product Features
The safety performance of miniature circuit breakers is directly related to electrical safety, which requires rivets to possess excellent overall performance. Through advanced manufacturing processes and strict quality control, we endow our products with three core advantages:
🔩
High-Strength Connection — Vibration-Resistant & Anti-Loosening
The cold forging process is adopted, and the strength of the rivet rod can reach grade 4.8 or above. After pressing and riveting, a stable connection structure is formed. Even in the vibration environment of long-term circuit breaker operation, the connection remains tight — eliminating hidden dangers of poor contact, overheating, and fire caused by loosening.
🌡️
Stable Performance — Adaptability to Extreme Environments
After passing multiple rounds of rigorous testing including high and low temperature tests (-40℃ to 120℃), aging resistance tests, and salt spray tests, the product maintains stable mechanical and electrical properties in extreme environments such as high temperature, humidity, and dust — suitable for homes, industrial plants, and commercial complexes.
Frequently Asked Questions
What rivet sizes can be customized for miniature circuit breakers?
We offer full customization with shank diameters from 0.8mm to 5mm and lengths from 1mm to 10mm. All dimensions are machined to customer drawings or samples with a tolerance of ±0.01mm.
What structural types of rivets are available?
We provide stepped rivets, semi-hollow rivets, and solid rivets, each suited for specific functions such as conductive connections, insulation fixation, and component fastening within circuit breaker assemblies.
What materials and surface treatments are offered?
Base materials include copper, copper alloy, stainless steel, and iron. Surface treatment options include silver plating, tin plating, and zinc plating, selected based on conductivity and environmental requirements.
How do these rivets perform in high-vibration environments?
Thanks to the cold forging process, rivets achieve grade 4.8 strength or above. Once installed, they form a stable connection that resists loosening even under prolonged vibration, preventing overheating and fire risks.
Are these rivets suitable for outdoor or harsh environment applications?
Yes. Our rivets are tested across temperature ranges from -40℃ to 120℃ and pass aging resistance and salt spray tests, making them reliable for industrial plants, commercial complexes, and other demanding environments.
Can samples or custom drawings be submitted for production?
Absolutely. We accept both customer-provided drawings and physical samples as the basis for customization, ensuring dimensional accuracy and compatibility with your specific circuit breaker model.
