Customized Aluminum Blind Rivets for Molded Case Circuit Breakers - China Suppliers & Factory
Product Overview
In the safety protection system of power distribution systems, molded case circuit breakers (MCCBs) serve as core protection devices, and the reliability of the connections of their internal components directly determines the operational stability and service life of the equipment. Aluminum blind rivets, as critical internal fasteners of MCCBs, bear multiple responsibilities, including component fixation, circuit insulation, and structural reinforcement. Having cultivated expertise in the field of customized fasteners for many years, we specialize in developing and manufacturing customized aluminum blind rivets for MCCBs, offering enhanced adaptability and more stable performance. These rivets precisely match the structural requirements of different MCCB models, building a solid first line of defense for the safety of power equipment.
Product Features
Made of high-purity 6061, 5052 and other special aluminum alloy materials, combining lightweight characteristics with excellent shear strength. While reducing the overall weight of the circuit breaker, it stably withstands stress caused by component vibration and current thermal effect, avoiding safety hazards from loose connections.
Through professional surface treatment processes such as anodizing and passivation, a dense protective layer is formed on the rivet surface, effectively improving electrical insulation performance and preventing leakage risks. It also resists humid environments and corrosive gases, extending service life by more than 1.5× that of standard parts.
Utilizing an optimized core-pulling structure design, it achieves rapid single-sided riveting without requiring complex operating space. The rivet sleeve expands precisely, forming a tight-fitting "safety lock" structure. After locking, the rivet head flatness error is controlled within 0.01mm, fully meeting precision assembly requirements.
Full-Dimensional Customization
We can precisely customize rivet products with diameters of 2.4mm–6.4mm and lengths of 5mm–35mm according to the riveting hole diameter and interlayer thickness of circuit breaker components. The rivet head style supports multiple options such as convex head and countersunk head, and the clamping range can be accurate to 0.1mm, perfectly adapting to special space installation requirements.
For special working conditions such as high temperature and high humidity, special materials such as high-temperature-resistant aluminum alloy and corrosion-resistant alloy can be customized. By adjusting the alloy composition ratio, strength, toughness, and thermal conductivity can be precisely matched. For example, weather-resistant aluminum rivets customized for outdoor circuit breakers can withstand temperature fluctuations from -40℃ to 120℃.
We offer a variety of surface treatment options, including zinc plating, nickel plating, and black anodizing. Among them, the insulating anodizing process developed for precision circuit breakers can achieve an insulation resistance of over 10¹²Ω on the rivet surface, meeting the requirements for high-voltage applications.
Supports customization for special needs such as vibration resistance, anti-loosening, and color marking. For example, anti-vibration rivets customized for circuit breakers for rail transit can improve connection stability under vibration by adding a rivet sleeve texture design; gold, silver, and other marking colors can be customized according to assembly requirements to facilitate specification differentiation during the production process.
