NH Fuse Holder Silver-plated Contacts
Products Description
In the high-voltage power distribution architecture of electric vehicles (EVs) and energy storage systems (ESS), the NH Fuse Holder Silver-plated Contacts are not only mechanical support units but also critical transmission nodes for the main circuit current. Their contact resistance, thermal stability, and structural strength directly affect system efficiency, safety redundancy, and long-term service life. Addressing this demanding application scenario, we have launched a stamped and tapped fuse base manufactured from 99.99% high-purity copper T2Y2 (C1100), boasting an ultra-high conductivity of ≥98% IACS. Through precision metal forming and internal thread integration design, we achieve a highly efficient manufacturing path of "one-time stamping + direct tapping."
Product Advantages
Excellent Working Condition Resistance
The Copper Knife Set for NH Fuse material itself possesses excellent resistance to high and low temperatures and corrosion, allowing stable operation within an ambient temperature range of -40℃ to 125℃. It is suitable for complex working conditions such as outdoor driving and extreme climates for electric vehicles, while also exhibiting excellent vibration resistance, meeting EV vehicle vibration testing standards.
Strong Customization and Adaptability
We can customize the thread specifications of Copper Knifes for NH Fuse according to the fuse specifications, installation space, voltage level and other requirements provided by the customer, so as to adapt to different brands and models of EV fuses without the need for the customer to adjust the original circuit design.
Convenient and Efficient Installation
The modular design of Pure Copper Knife for NH Fuse combined with precise dimensional positioning allows for quick assembly and fixing of fuses without the need for complex tools, improving production efficiency, reducing assembly labor costs, and meeting the needs of large-scale electric vehicle production.
Main Functions
Fuse Fixing Function
The precision-designed Red Copper Knife for NH Fuse securely fixes the fuse to the designated position in the electric vehicle's high-voltage circuit, preventing displacement or detachment due to vibration and bumps during vehicle operation, thus ensuring circuit connection stability.
High-Voltage Conductivity Function
The Pure Copper Knife for NH Fuse is made of high-conductivity T2Y2 copper, achieving efficient and low-loss conductivity between the fuse and the high-voltage circuit, ensuring stable current transmission and providing a stable power supply to core components such as the electric vehicle's battery system and motor controller.
Circuit Protection Function
In conjunction with the fuse's overload and short-circuit protection functions, excellent contact performance and sealing design of Copper Knifes for NH Fuse prevent arcing and current leakage, avoiding circuit faults caused by poor contact and protecting the electric vehicle's high-voltage circuit and core components from damage.
Technical Features
Insulation Protection Technology
The Red Copper Knife for NH Fuse adopts an integrated insulation protection design, using high-temperature resistant and aging-resistant insulating materials. Combined with a sealed structure, it effectively prevents current leakage and arc breakdown, achieving an IP65 protection level, ensuring the safe operation of the circuit system and adapting to complex industrial environments.
Vibration Resistance and Anti-Loosening Technology
The Red Copper Knife for NH Fuse employs an anti-loosening thread design and contact locking structure. Combined with the excellent toughness of copper, it effectively resists high-frequency vibrations and equipment start-up and shutdown impacts in industrial settings, preventing fuse loosening and contact detachment, improving product operational stability, and meeting industrial equipment vibration testing standards.
Precision Dimension Control Technology
Using imported precision testing equipment (such as 2D image measuring instruments and thread gauges), key parameters such as product dimensions, thread accuracy, contact spacing, and silver plating thickness are tested throughout the entire process. Dimensional tolerances are controlled within ±0.008mm, ensuring precise fit between the Copper Knifes for NH Fuse and NH fuses and circuit systems, avoiding assembly gaps and poor contact.
