EV Fuse Copper Contact
In the high-voltage electrical architecture of new energy vehicles, the fuse serves as a core safety component for short-circuit and overload protection. Copper contact parts act as one of the most critical current transmission interfaces in its structure. EV Fuse Copper Contact are mainly used to connect the fuse element, external busbars, and the high-voltage circuit of the battery. Under normal operation, they ensure stable current conduction; in the event of a fault, they cooperate with the protection mechanism to achieve rapid circuit breaking.

Product Introduction
This EV Fuse Copper Contact is specially designed for the harsh on-board conditions of new energy vehicles. It is a core conductive contact component for overload and short circuit protection of electrical circuits. Unlike conventional industrial-grade copper contacts, it is designed with the core engineering requirements of electric vehicles, such as high and low temperature cycling, high frequency vibration, high current conduction, and long-term aging resistance. It uses high-purity copper substrate with precision molding and surface treatment processes to achieve the core functions of low contact resistance, high conduction efficiency, and long-term stable contact. It perfectly matches the three core technical indicators of vehicle fuses: melting response, temperature rise control, and mechanical durability. It is a key basic component for the safety redundancy design of new energy electrical systems.
Structural advantages
Integrated Molding, No Weak Points
Utilizing a precision cold heading and fine stamping integrated process, the Blade-type Fuse Contact is made of a single piece of dense oxygen-free copper, eliminating splicing and welding weak points. It resists vehicle vibration and high/low temperature cycling, preventing loosening, cracking, and sudden resistance changes, ensuring structural stability and durability.
Adaptive contact, stable conduction
The end face features a micro-arc surface + flat composite structure, precisely matching the fuse element, optimizing the conductive area to reduce resistance, and eliminating loose connections. Side positioning slots facilitate quick assembly, prevent misalignment, and are compatible with all types of production lines, ensuring consistent conductivity.
Compact Structure, Fits Vehicle Space
The streamlined and lightweight design reduces redundant dimensions and saves space. It features a built-in micro-heat sink for rapid heat dissipation and temperature control without affecting fuse response, perfectly adapting to the confined spaces of vehicle environments such as battery packs and PDUs.
Customized processing flow
Drawing Submission and Process Assessment: The customer provides CAD/3D drawings of the EV copper contacts, and our company conducts a specialized assessment of the Fuse Blade Contact molding process and mass production costs.
Sample Order and Mold Prepayment: Once the quotation is agreed upon, the customer places a sample order and prepays 50% of the copper contact mold fee for Blade Fuse Terminal.
Mold Development and Sample Delivery: Our company initiates the development of automotive-grade precision molds. Upon completion, we send 1-20 Fuse Terminal samples to the customer for performance testing.
Sample Acceptance and Mold Final Payment Settlement: Once the sample's contact resistance and dimensional accuracy meet the standards, the customer settles the remaining 50% of the mold payment for Fuse Knife Contact.
Bulk Order and Mass Production Commencement: The customer places a large-scale order and prepays 30% of the payment. Our company commences mass Fuse Terminal of the copper contacts.
Finished Product Inspection and Final Payment Shipment: After all finished Blade Fuse Terminal pass comprehensive testing and a list is issued, the customer pays the final payment, and our company ships the product via the designated logistics company.
