Copper Outer Cap For Eaton Bussmann Fuse
Products Description
The Copper Outer Cap for Eaton Bussmann Fuse is a conductive protective component specifically designed for fuse applications. Fabricated from high-purity T2Y2 red copper through precision stamping and annealing processes, it serves to enclose the fuse body, providing mechanical protection, electrical connectivity, and environmental isolation. This component acts as a critical auxiliary element in ensuring the safe interruption of industrial power distribution systems during overcurrent faults, and is widely utilized in high-voltage, high-current electrical protection circuits.
Design Advantages
Cross-Sectional Optimization for Current Flow and Heat Dissipation
Through current density and thermal simulations, the Copper Fuse End Cap for New Energy Vehicles's wall thickness, internal cavity geometry, and contact area with the ceramic body are optimized. This ensures optimal current distribution and heat dissipation pathways while fully satisfying mechanical strength requirements.
Structural Reinforcement to Withstand Short-Circuit Electrodynamic Forces
Critical stress-bearing zones-such as the base and neck of the Copper End Caps Round-are structurally reinforced through localized thickening and the incorporation of reinforcing ribs. This enhances their resistance to bending and torsion, enabling them to withstand the immense electrodynamic shock generated by anticipated short-circuit currents.
Interface Design Optimized for Automated Assembly
The Copper End Cap for New Energy Fuse's external geometry, gripping features, and error-proofing markings are all meticulously designed with automated assembly requirements in mind. This facilitates rapid, precise gripping, alignment, and subsequent crimping or welding operations within automated fuse production lines.
Material Composition
| Purity Assurance | The oxygen content of T2Y2 red copper for PV Fuse Copper Outer End Cap is controlled to an extremely low level (<0.003%), with a copper content of ≥99.95%. This high purity eliminates the negative impact of impurities on electrical conductivity, ensuring that resistivity approaches its theoretical limit (approximately 1.724 × 10⁻⁸ Ω·m). |
| Mechanical Properties | Utilizing a soft-temper (Y2) material, it exhibits excellent ductility and toughness. During the stamping and forming process, the material is resistant to cracking; furthermore, through cold working, it develops appropriate hardness in critical contact zones. This dual characteristic ensures the tightness of the crimped connection while simultaneously mitigating the risk of brittle fracture caused by excessive hardness for Copper End Caps for PV Fuse. |
| Corrosion Resistance | In atmospheric environments, red copper for Copper Cap for Hybrid Car Fuse forms a dense oxide film (patina) that effectively prevents deep-seated corrosion, making it particularly well-suited for long-term use in industrial settings. |
Working Principle
Current Path
The Copper End Caps Round is directly welded or crimped to the terminal of the fuse element inside the device. Current flows from the external terminal, through the end cap, into the fuse element, and then exits through the end cap at the opposite end. The use of oxygen-free copper-a material characterized by low resistivity (≤ 0.017241 Ω·mm²/m)-serves to minimize contact resistance and temperature rise.
Mechanical Fixing
The Copper Fuse End Cap for New Energy Vehicles securely fasten the fuse tube, quartz sand filler, and fuse element assembly into a single, cohesive unit, thereby preventing the internal structure from shifting or becoming displaced due to vibration or thermal expansion.
Environmental Sealing
A protective barrier is established between the Copper End Caps for PV Fuse and the fuse tube through either an interference fit or the application of sealing compound. This barrier prevents the ingress of moisture, salt spray, and dust into the interior of the fuse, thereby safeguarding the fuse element against oxidation or moisture-induced damage.
