Copper Cap For Hybrid Car Fuse
Products Description
In hybrid electric vehicles (HEVs) and new energy electric drive systems, Copper Cap for Hybrid Car Fuse not only provides overcurrent protection, but the conductivity and mechanical reliability of their structural components are also crucial. The copper cap, as a vital connection and encapsulation component at both ends of the fuse, directly affects overall conductivity, temperature rise control, and fusing response accuracy.
This product employs a dual-structure design: an outer cap and an inner cap.
The outer cap is made of high-purity T2Y2 copper to ensure excellent conductivity. The inner cap is primarily made of high-strength brass, balancing mechanical strength and processing stability.
This combined design achieves a balance between conductivity, weldability, and structural stability, representing the mainstream technology in current new energy vehicle fuse components.
Manufacturing Advantages: End-to-End Control from Raw Materials to Finished Products
Vertically Integrated Supply Chain
Raw materials are sourced from top domestic copper groups, with each batch accompanied by a spectral analysis report to ensure the purity of the T2Y2 material for the Copper Outer Cap for Industrial Power Fuse.
Fully Automated Stamping Line
Equipped with 80-160 ton high-speed precision stamping machines, enabling 24-hour continuous operation, with an annual output capable of supporting the needs of millions of new energy vehicles.
Advanced Welding and Assembly
For Copper Outer Cap for Eaton Bussmann Fuses requiring composite welding, we employ laser spot welding or resistance welding technology, resulting in full welds with minimal heat-affected zones, preserving the original crystal structure of the copper.
Key Functions and Application Advantages: Reshaping the Safety Boundaries of Hybrid Systems
| Structural Support Under Extremely High-Speed Disconnection | When a short circuit occurs in a hybrid system, the current rise rate is extremely high. The robust ends formed by the Copper Outer Cap for gG gL Fuse and brass inner cap can withstand the enormous shock wave generated by the instantaneous vaporization of the molten material, preventing the fuse from physically exploding. Its strong mechanical strength provides an indestructible physical container for the smooth melting, arcing, and eventual safe disconnection of the molten material. |
| Adapting to High-Vibration Vehicle Environments | Hybrid engines generate complex spectral vibrations during start-stop operations. The interference fit between the fully stress-relieved brass inner cap and the ceramic tube has extremely strong anti-loosening capabilities, avoiding internal contact problems or abnormal noises caused by long-term vibration, thus improving the overall vehicle NVH (noise, vibration, and harshness) performance and electrical safety. |
| Optimizing Power Distribution Unit (PDU) Space | Thanks to the excellent conductivity and heat dissipation properties of the Outer Cap, system engineers can appropriately reduce the safety heat dissipation gap around the fuse when designing the PDU. The high thermal conductivity copper cap acts as a "miniature heat sink," helping the PDU achieve a more compact design with higher power density. |
Manufacturing Strength and Quality Control System
As a source factory, we deeply understand the zero-tolerance policy for consistency in automotive parts manufacturing.
Independent Mold Development: We possess an independent mold processing center, enabling us to go from drawings to samples in as little as 7 days, supporting rapid switchover from small-batch trial production to large-scale delivery.
Full-Process Testing: Equipped with a 2D imaging system, Rockwell hardness tester, salt spray tester, and continuity tester. Each batch of Copper End Caps Round has a unique traceability code, ensuring full lifecycle traceability from raw materials to finished products.
IATF 16949 System Implementation: Although we are pragmatic and low-key, we strictly implement automotive industry quality management system standards on the production floor, using APQP and PPAP tools to manage project development processes.
