EV Fuse Blade Contact
In high voltage and high current application scenarios such as new energy vehicles (EVs), photovoltaic power generation (PV), and energy storage systems (ESS), fuses are not only the "safety valve" of the circuit, but also the last line of defense for system safety. As the core current carrying and arc extinguishing mechanism inside the fuse, the performance of the EV Fuse Blade Contact directly determines the response speed and breaking ability of the fuse under short-circuit faults.

Product Introduction
As the core conduction and protection component of fuses in high-end power systems such as new energy vehicles and photovoltaic energy storage, EV Fuse Blade Contact focuses on the core requirements of circuit safety protection under high voltage and high current conditions. It is designed specifically for harsh industrial and automotive engineering scenarios, accurately solving industry pain points such as high conductivity loss, unstable contact, insufficient corrosion resistance, and single adaptability of traditional contact blades. It provides customized contact solutions that are reliable, compatible, and cost-effective for global B-end buyers and engineering technical teams, helping customers improve their competitiveness in end products and reduce production and maintenance costs.
Core applicable engineering scenarios
new energy vehicles
Core high-voltage circuits such as power battery pack protection, drive motor control system, on-board charger (OBC), high-voltage distribution box (PDU), etc., are suitable for various new energy vehicle models such as pure electric and hybrid. The EV Fuse Blade Contact meets the strict requirements of high-voltage, vibration, and alternating high and low temperature working conditions in vehicles.
01
Photovoltaic and energy storage
Fuse Knife Contact is suitable for circuit protection of photovoltaic inverters, photovoltaic combiner boxes, energy storage battery modules, energy storage converters (PCS) and other equipment. It is suitable for various photovoltaic energy storage projects such as large ground photovoltaic power stations, distributed photovoltaics, household energy storage, etc. outside the home.
02
Industrial power
Fuse Contact Blade is applied to UPS DC links, industrial distribution boxes, high and low voltage complete equipment, NH fuses, BS fuses, as well as fast fuse systems for industrial equipment such as machine tools, ships, and rail transit. It is suitable for high-frequency start stop, high load, and high dust industrial working conditions.
03
Special electrical
Copper Blade for Fast Fuse is applied in medical equipment, aerospace supporting electrical equipment, emergency power systems and other scenarios that require extremely high reliability and stability of contacts, meeting the low loss and long life requirements of precision electrical equipment.
04
production process
Basic molding process
The basic forming process includes two steps: stamping and stretching. Stamping initially shapes the prototype of the contact blade and ensures the basic dimensions of the Metal Copper Blade, while stretching precisely controls key dimensions to avoid substrate damage.
Connection and molding optimization process
The connection and forming optimization process focuses on the structural stability and adaptability of the Cylindrical Body Contact Knife, covering riveting, metal cold pressing, and hot stamping. Riveting ensures stable connection of multiple components, while cold pressing and hot stamping optimize appearance performance and adapt to complex structures.
welding process
The welding process provides multiple precise solutions that are suitable for different scenarios and production needs of Copper Knife. Various types of welding ensure the quality and efficiency of conventional connections, high-voltage adaptation, precision machining, and large-scale production.
Surface treatment and customized processing technology
Surface treatment and customized processing are the final steps to enhance the performance of Copper Contact and adapt to customized requirements. Electroplating optimizes conductivity and corrosion resistance, and CNC machining can accurately achieve complex customized dimensions.
