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.
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.
Considering the working environment of the circuit breaker, we offer a variety of base materials and surface treatment options:
⚠️ Conductive circuit rivets are made of high-purity copper with silver plating, increasing conductivity by more than 30%.
🛡️ Casing fixing rivets are made of highly corrosion-resistant 304 stainless steel, extending the service life of the equipment.
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 two core advantages:
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 operation of circuit breakers, the connection stays tight — eliminating hidden dangers of poor contact, overheating, and fire caused by loosening.
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.
